[Unreleased]

Fixed

• extract-zip eliminated from the dependency graph (Dependabot #86, GHSA-7pqw-9j4j-h8q3 / GHSA-jmr9-qjv8-65gv): the vulnerable package was reachable only via @lhci/cli's hard-pinned lighthouse@12.6.1 → puppeteer-core → @puppeteer/browsers@2.x chain. A pnpm-workspace.yaml override exact-pins lighthouse to 13.4.1, whose modern @puppeteer/browsers@3.x dependency replaced extract-zip with modern-tar entirely — the package now has zero occurrences in the resolved graph. Lighthouse 13.4.1 requires Node >=22.19, so the repository's own engines.node floor is raised to match. PR #682.
• Tauri release build now fails fast on a plugin version mismatch: tauri-build.yml's cross-platform bundle matrix (~45 min) previously started right after tag-signature verification, with no cheap check for the exact Rust/npm plugin mismatch that broke every platform's v1.28.5 release build. Added a parity-preflight job (checkout + one dependency-free Node script, no pnpm install) that runs check-tauri-plugin-versions.mjs before the bundle matrix starts, gated behind verify-release-tag so no repository code runs on an unverified release tag. On both workflow_dispatch and tag pushes. PR #684.
• PWA: a failed precache can no longer displace a working service-worker generation (#525): install previously caught a cache.addAll()/admission-marker failure without rethrowing, so the browser still recorded the worker as successfully installed; it could later activate and claim clients with an incomplete cache and no working fallback. install now rethrows on failure so the whole installation rejects — a worker that never reaches installed can never activate, claim clients, or receive an update message. The activate-side admission check is kept as defense in depth, returning immediately (no pruning, no clients.claim()) if it is ever reached without a completed marker. Also fixed a duplicate-precache-request risk the lifecycle fix would otherwise have turned fatal: VitePWA's injected manifest independently discovers index.html/offline.html/favicon.svg, colliding with the same files already listed explicitly in PRECACHE_URLS; these are now resolved and deduplicated at runtime (against each other too, not just the explicit list) before reaching cache.addAll(), while the manifest keeps its content-hash revision tracking for update detection. PR #699.
• A governed PR can no longer merge without a CHANGELOG reference to itself: the completeness gate in check-doc-metrics.mjs only enforced a PR-number reference in [Unreleased] after squash-merge, once the commit already carried (#N) — nothing stopped a governed PR from merging without ever adding the entry, even though its real PR number is knowable before merge. Recurred three times (#678→#679, #684→#685, #699→#700). A new pre-merge admission gate (.github/workflows/pr-changelog-reference.yml + check-pr-changelog-reference.mjs, run from the PR's base ref to prevent self-weakening) now fails a governed PR's CI unless [Unreleased] already references it as PR #<N>. PR #705.

Documentation

• Post-release v1.28.6 truth sync: removed the now-stale release-candidate markers from README.md and CHANGELOG.md now that the v1.28.6 tag and GitHub Release are published, and recorded real release-gate evidence in AUDIT.md for both v1.28.6 (main CI/CD run, CodeQL, the pre-tag exact-SHA Tauri qualification, tag-triggered Tauri/CI/Docker runs, published release assets) and v1.28.5 (the desktop-build failure and its independently-successful Docker/GHCR publish). PR #681.

[1.28.6] — 2026-09-09

Fixed

• Tauri plugin Rust/npm version parity restored: tauri-plugin-http and tauri-plugin-notification had drifted ahead of their npm counterparts (@tauri-apps/plugin-http, @tauri-apps/plugin-notification) after #661 bumped only the Rust side, failing every platform's Tauri release build. Bumped the npm packages to match; added check-tauri-plugin-versions.mjs, a cheap CI guard catching this class of mismatch before the next release tag instead of at tag-triggered release time. PR #678.
• CHANGELOG completeness-gate PR-number reference restored: the Tauri plugin-parity entry above passed PR-branch CI but failed on resulting-main right after squash-merge. PR #678's number was already known before merge; only the final squash commit's SHA/subject did not exist yet. The PR-branch check does not enforce the current PR's own already-known number against [Unreleased], only resulting-main's commit history — so PR CI stayed green, and only after the squash commit landed on main did docs:check correctly flag the missing reference. PR #679.

[1.28.5] — 2026-09-09

This tagged release's desktop build never completed. The tag-triggered Tauri desktop release workflow failed on every platform (Windows/Linux/macOS) with the Rust/npm plugin version mismatch fixed in [1.28.6] above, so no GitHub desktop Release or installer/updater assets were ever published for v1.28.5 — those bundle jobs failed before producing assets. This was a desktop-build-specific failure: the separate Docker/GHCR publish workflow for this tag succeeded, so a container image for v1.28.5 does exist. The v1.28.5 git tag itself is intentionally never deleted, moved, or re-tagged; it remains permanently bound to its original commit as the historical failed/incomplete desktop-release cut. v1.28.6 is the corrected, complete release.

Added

• Project schema-version classification (Slice A, #553): PROJECT_SCHEMA_V1 as a fresh production version marker, disjoint classification (LEGACY_UNVERSIONED/SUPPORTED_OLDER/UNSUPPORTED_OLDER/CURRENT/FUTURE/MALFORMED), raw/header parsing before typed parsing so a FUTURE document with a breaking shape still classifies FUTURE rather than MALFORMED, and the LEGACY_TO_V1 in-memory admission primitive. PR #618.
• Schema-version classification observed on IDB project load (Slice B, 1/N, #553): the first ingress path wired to Slice A's classifiers, observation-only (classify and log, never alter load behavior, never throw), matching the established Core shadow-validation pattern. PR #619.
• Canonical document projection foundation: establishes the canonical parser/import/admission boundary that retains the original JSON text alongside a bounded typed projection, the foundation Slice C's admission primitive builds on.
• Explicit legacy-to-v1 admission primitive (#653): the non-destructive LEGACY_TO_V1 in-memory admission path recognizes, fully validates, losslessly overlays the V1 version marker, and revalidates the destination. PR #653.
• Filesystem admission converged after #654 (#658): carries forward canonical filesystem admission and closes legacy editable-admission authority gaps. PR #658.

Fixed

• schemaVersion now enforces raw integer grammar (#553): rejects rounded fractional schema versions and non-number schema-version tokens instead of silently coercing them. PR #621.
• Canonical document projection now reuses its own parsed input instead of re-parsing, removing a redundant-parse divergence risk between the raw and typed projections.
• Projection failure now retains the raw header verdict instead of discarding the already-classified version header when the typed projection itself fails.
• Unsupported-project startup copy added alongside the existing migration-gap copy, so a project whose schema version this build cannot open at all gets its own distinct startup message rather than reusing the migration-gap wording.
• Migration-gap startup copy now distinguished from the unsupported-project case (#656): the two failure classes previously shared wording; each now gets copy specific to its actual cause. PR #656.
• PR-size exception governance hardened (#657): closes control gaps in how per-PR size-ceiling exceptions are recorded and validated. PR #657.
• Security docs no longer cite closed PR #356 as active desktop-encryption remediation: docs/SECURITY-THREAT-MODEL.md and docs/IDB-ENCRYPTION.md both asserted PR #356 was the active/pending remediation for desktop plaintext storage after it was closed as superseded on 2026-08-18. Rewritten to anchor on the living Ledger-row-9/R-15 state instead of a PR number, and check-doc-metrics.mjs now mechanically rejects an unqualified live/pending-remediation claim tied to a bare PR number in these two files. PR #673.
• CHANGELOG completeness-check upgrade, backfill Unreleased (audit F-2, PR #674): scanUnreleasedTruth previously accepted any non-empty [Unreleased] section forever, so a single unrelated bullet let arbitrarily many later feat/fix/perf commits go completely undocumented — 13 real commits since v1.28.4 had gone unrecorded. It now requires every governed commit to be individually referenced by PR number or subject slug, naming any that aren't; this section was backfilled with all 13 currently-undocumented entries above.
• Completeness-check review findings addressed: PR-number matching now requires a non-digit boundary (a bare substring check let #65 satisfy #656), subject-slug matching is scoped to one changelog entry at a time instead of the whole section, each matched entry is claimed so one generic bullet can't simultaneously "document" multiple different commits, a numbered commit now requires its exact PR number rather than ever falling back to a slug match, and full per-commit completeness is enforced only outside pull_request CI context (an un-numbered commit there is exempted — a PR's own git-log range enumerates every commit unique to that branch, not the one commit that will exist after squash-merge, so a review-fix follow-up commit can't reference itself in advance — while an already-numbered commit from a separate, already-merged PR sitting in the same range stays fully enforced).
• Stop reading the GitHub event name as the completeness check's own default: the pull_request-context parameter defaulted to reading GITHUB_EVENT_NAME directly, but that environment variable is ambiently visible to the Vitest test process too when the whole suite runs inside a pull_request-triggered job — the pure function's default is now hardcoded false; only the real CLI invocation reads the actual environment.

Security

• AI/session attribution now rejected in commits and PRs: a fail-closed guard (check-commit-attribution.mjs, a commit-msg hook, a pre-push scan of outgoing commits, and a CI check on the commit range and PR title/body) blocks Claude/Anthropic attribution trailers, session URLs, and generated-by footers before they can land in repository history. PR #672.

Documentation

• Post-release v1.28.4 truth sync: removed the now-stale release-candidate markers from README.md and CHANGELOG.md now that the v1.28.4 tag and GitHub Release are published, and recorded real release-gate evidence in AUDIT.md (main CI/CD run, CodeQL, GitHub Pages deploy, tag-triggered Tauri/CI/Docker runs, published release assets).

[1.28.4] — 2026-09-05

Fixed

• PWA first-install unprompted reload: clients.claim() on activation fired controllerchange on the very first-ever page load, not only on genuine updates, causing every first-time visitor to undergo one automatic reload shortly after landing. Fixed via absolute-URL own-worker identification, shared-origin foreign-worker exclusion, persistent installation history, event queuing during classification, and recovery when getRegistration() fails. A narrow residual — two tabs racing the very first-ever activation of this origin's service worker so closely that one tab's evidence reads as "already installed" — requires real cross-tab coordination and remains open as #614. Fixes #585, PR #613.
• Service-worker cache reads are now positively ownership-scoped: every caches.match() call in the fetch handler and offline fallback now specifies its owning cache by name, closing a shared-origin (e.g. qnbs.github.io hosting multiple projects) cache-read isolation gap. Fixes #514, PR #612.
• Factory Reset could reboot back into Settings instead of Welcome Portal: a stale view-carrying URL hash survived wipeAllAppData()'s reload, and readInitialView() read it with higher priority than checking whether a project still existed. PR #592.
• Desktop project corruption is now preserve-first: a corrupt desktop project is quarantined (moved to quarantined-projects with a collision-safe name) rather than risking deletion; the destructive IndexedDB-reset action is no longer offered for project-load failures. PR #542.
• Desktop filesystem I/O errors now get a distinct, truthful recovery action: separated from corruption-quarantine and generic-storage-reset, so each failure class only exposes the action that's actually safe for it. PR #545.
• Intentionally cleared project metadata no longer reappears: an empty title/logline set by the user could be silently repopulated during returning-user bootstrap. PR #546.
• Factory Reset could report success while user data remained: deleteDatabase() treated a genuine onerror or an onblocked event (another connection still open) as success, so wipeAllAppData() could resolve without every database actually being deleted. onerror now rejects, and onblocked waits for the connection to close before giving up. PR #596.

Accessibility

• Welcome/Home dashboard WCAG AA contrast and a repaired prefers-reduced-motion cascade (the override now correctly wins over equal-specificity base rules); default appearance preset is now default for new and invalid-legacy sessions. Fixes #565, PR #609.
• ManuscriptEditor deferred-mirror contrast raised from 4.45:1 to ~5.10:1. PR #560.

Security

• fflate ZIP64-parsing DoS, used by this app's export path: overridden to 0.8.3. PR #595.
• Routine dependency maintenance: xmldom/fast-uri/qs floor bumps (PR #587), log crate in src-tauri (PR #561), codeql-action group (PR #562), actions/setup-node (PR #594).

Documentation

• R-15 secure desktop storage — design contract admitted, implementation not started: the full storage/migration/recovery contract (S5-A, S5-B1, S5-B2, S5-B3) is now defined and its cross-contract consistency audited. No code has shipped yet; desktop project files remain documented as plaintext until this implementation lands. PRs #564, #580, #581, #582, #584.

Tests

• Visual regression testing repaired: VRT baselines were directory listings, not the application — the gate was not protecting against real visual regressions. Now reaches actual app routes with real baselines and a proven negative control demonstrating a visible regression fails the gate. PR #610.
• Async, generation/epoch-based IDB reset-quiescence contract across 9 service modules, closing every long-lived connection before a factory reset deletes anything (PR #596; issue #532's own WelcomePortal entry-nondeterminism root cause is a related but distinct class and remains open). WelcomePortal E2E recovery navigation made locale-independent (PR #590).

[1.28.3] — 2026-08-27

Documentation

• Post-release v1.28.2 truth sync: removed the now-stale release-candidate markers from README.md and CHANGELOG.md, and corrected AUDIT.md's release-gate entry (macOS artifacts don't each get a Minisign .sig — only .app.tar.gz does; and issue #527's release-relevance wording was overstated — the affected code shipped in v1.28.2 even though the main-push verification run (33064552219) that gated this release didn't trigger it; only the separate, later tag-triggered CI/CD run did).

Fixed

• Onboarding bootstrap-effect race that could skip the welcome portal: hooks/useApp.ts initialized isPortalActive to false and only flipped it true via a mount effect, even though isNewUser is already resolved synchronously before <App> mounts. A separate project-bootstrap effect (repairs raw-i18n-key project fields, or seeds a fresh blank project) only guarded on isPortalActive/isI18nReady/project, missing the isInitialLoad guard a sibling effect in the same file already uses — occasionally letting a blank project get auto-seeded before the portal-activation state change landed, skipping the welcome portal for a new user. Fixed both: synchronous isPortalActive initialization, and the missing isInitialLoad guard (extracted into hooks/useProjectBootstrapEffect.ts for direct test coverage). Fixes #527, PR #530.
• export.spec.ts E2E precondition assumed WelcomePortal unconditionally: waitForSpaReady() succeeds on either WelcomePortal or an already-mounted main shell, but the test's beforeEach clicked "Start a New Project" unconditionally, causing spurious CI failures whenever a cold boot landed in the main shell instead — a startup-state precondition gap, not a #527/#530 regression. Added ensureWelcomePortalEntry() (tests/e2e/helpers.ts), which recovers via the real Settings → Data & Backups → Factory Reset flow when needed — including re-checking both startup shapes after its own internal reload, since that reload can itself race a pending ~1s debounced autosave — and a stable data-testid="welcome-portal" on WelcomePortal.tsx's root so portal detection no longer depends on translated button text. Regression coverage for both startup shapes, a non-English persisted-language boot, and the internal-reload race. This fixes the test-harness symptom, PR #533; issue #532's root cause (how a persisted project can appear before any test action runs) remains open and unexplained.

[1.28.2] — 2026-08-27

Fixed

• Service-worker cache deletion is now positively ownership-scoped: every service-worker-managed cache-deletion site (non-Tauri activation cleanup, the Tauri unregister path, the user-initiated "clear cache" action, and Factory Reset) now matches against an exact, closed set of this app's own cache-name families before deleting anything, closing a shared-origin data-deletion risk where an unrelated cache could be swept up by a blanket prefix or unconditional caches.keys() sweep. Local AI model caches (Settings → AI → Clear Local Models) are a separate deletion authority and are addressed by the next entry; Factory Reset does not yet clear them — tracked in #526.
• Local AI model cache clearing now matches exact vendor bucket names, not a loose substring: "Clear Local Models" previously matched any cache whose name merely contained webllm, mlc, tvmjs, or transformers — broad enough to catch an unrelated cache like other-transformers-assets on the shared origin. It now matches only the exact CacheStorage bucket names these two vendor libraries actually create.
• Desktop filesystem corruption/I-O failures now fail closed, not silently absent: a corrupted or unreadable saved project file used to decompress/parse into a fake empty object and be treated as "no saved project" — risking a subsequent autosave silently overwriting the only remaining copy. Corruption and I/O failure are now distinct, typed, thrown errors the caller must handle explicitly; genuine absence is unaffected.
• PWA service-worker updates flush pending state before reloading: the visible tab now retry-flushes in-flight persistence (with a bounded final attempt and timeout) before a forced update reload, instead of reloading unconditionally on the assumption that autosave alone made it safe. This is a bounded mitigation, not a closed invariant — full cross-tab write coordination remains tracked separately (#480/#485); the residual risk after this fix is documented in #518.
• DOCX export now produces a real DOCX file everywhere it's offered: selecting DOCX in the in-app export dialog, the Writer export view, and the desktop file-save export path all previously silently wrote a Markdown-shaped file with a .docx extension. All three now build a genuine docx-package document and write real binary output.
• GitHub Pages deploy no longer silently skips on main pushes: the deploy job's default admission gate inherited GitHub Actions' skip-propagation from unrelated, legitimately-skipped upstream jobs (PR-only governance checks, path-scoped Rust gates) even when the real required aggregator had genuinely succeeded — the live GitHub Pages mirror had been intermittently stale since 2026-08-20 and consistently stale since 2026-08-26. Now gated explicitly on the aggregator's own result.

Documentation

• Onboarding install command corrected: README/CONTRIBUTING pointed contributors at a bare pnpm install, which skips --frozen-lockfile and this repo's own dependency-fingerprint check. All onboarding paths now point at the frozen-lockfile reconcile command.
• Desktop installer signing language narrowed to match reality: README claimed desktop installers were generically "signed"; only the auto-update manifest's per-platform Minisign signatures are produced by default — OS-level code signing (Authenticode, notarization) is not currently configured in CI.

Added

• Structural workflow-policy YAML authority: a real-parser (not regex) validator for every .github/workflows/*.yml and .github/actions/**/action.yml — top-level permissions, the needs: graph, SHA-pinned action references, and the publishing boundary. Runs first in CI, before any job invokes the governed setup composite action.
• Tiered PR-size governance: advisory target/hard/docsGovernance limits and a blocking absolute ceiling on changed files, meaningful lines, and commits, with a dedicated profile for all-documentation PRs. Excludes generated locale bundles, the pnpm-lock.yaml churn, and content-guard's own mirrored community-templates/index.json from the size calculation so an atomic i18n or lockfile change can't be falsely flagged; runs the base ref's own copy of the checker so a PR touching it can't raise its own limits.
• Intel macOS qualification-only build lane: a workflow_dispatch-only, non-publishing verification lane for the macos-15-intel runner class (GitHub's current replacement for the retired macos-13 label), with no signing secrets and no release artifacts.

Changed

• Pre-push evidence and local-admission tooling reconstructed as smaller, independently reviewed slices: canonical path-evidence completeness, change-aware local checks, bounded subprocess lifecycle for the pre-commit/pre-push runners, working-tree-vs-push divergence detection, and exact-localSha dependency-manifest compatibility proof.
• Qt/PWA native desktop architecture-governance roadmap reconciled: Wave 2.5 amendment, gates G1.5/G2.5, and reuse-ownership authority folded into the canonical roadmap and ledger docs.

Security

• google/osv-scanner-action 2.5.0 → 2.5.1.
• docker/setup-buildx-action 4.2.0 → 4.3.0.

Quality and governance

• The frozen reconstruction-source PR was fully reconciled: every still-required piece was rebuilt fresh against current main and merged through small, independently reviewed PRs; every other piece was already shipped through a separate implementation or is a deliberately deferred architecture question with durable issue tracking.

[1.28.1] — 2026-08-23

Added

• Scenario/Screenplay canonical projection workspace: the new workspace exposes a renderer-neutral projection for scenario and screenplay work while keeping the existing TypeScript authority intact.
• Core project validation shadow caller: desktop loads now observe the bounded Rust project validation verdict through DesktopPlatform; this is observation-only and does not switch authority from the existing TypeScript path.

Fixed

• Writing-overlay immediacy: overlay feedback is now visible without waiting for a later render cycle.
• Serialized persistence protection: overlapping persistence writes are coordinated so a later save cannot race an earlier save and corrupt the durable project state.

Security

• Verified release source history: signing doctor, local commit/push enforcement, exact-range verification, annotated-tag enforcement, and GitHub Verified checks now form the release-source trust boundary.
• Supply-chain monitoring: the daily OSV workflow and hardened pnpm bootstrap/version pinning extend the existing dependency and CI security controls.

Quality and governance

• Policy and mutation coverage: CI authority, selector/AI-core mutation oracles, and the packaged editor readability oracle were strengthened for this release line.
• Native lifecycle truth: the #332 lifecycle evidence and Qt early-killer gates are documented without claiming packaged closure.

Release boundaries

• Packaged Linux lifecycle/Alt+Tab validation for #332 remains pending; reporters should validate the new .deb using the documented lifecycle, Alt+Tab, and persistence protocol.
• Packaged dark/sepia/PWA-versus-packaged readability validation for #341 remains pending; publication or CI does not close that issue.
• PWA remains first-class, Tauri remains transitional, and Qt remains the future native target behind its evidence gates.
• No unsupported macOS Intel artifact is claimed; only artifacts actually produced by the release workflow belong in updater metadata.

[1.28.0] — 2026-08-21

Added

• Cloud model catalog defense-in-depth: current Anthropic, OpenAI, and xAI model IDs now share one typed catalog across settings, fallbacks, and the Claude proxy allowlist.
• Native bundle and translation-quality floors: bundle budgets now distinguish entry, vendor, regular JS, and WASM assets; CI also enforces the existing translation coverage/outlier floor.
• Renderer-neutral Rust Core seed: crates/worldscript-project now provides headless project schema, validation, migration, plain JSON I/O, and a test/CLI harness, with one narrow Tauri validation command wired through the cross-workspace path dependency.
• Rust TaskSupervisor bounded text proof: adds bounded renderer-neutral text.analyze and text.diff tasks, typed qualification wrappers, deterministic LCS/whitespace contracts, and explicit fallback to the existing TypeScript path; no production caller is switched yet.

Fixed

• Release-truth guard: docs:check now verifies the release-tag frontier, package/tag relationship, README release badges, and non-empty [Unreleased] history without treating tagless or shallow checkouts as a false failure.
• Spotlight tour theme: the post-rebrand driver.js popover now binds to its WorldScript CSS selector, with a regression test protecting the binding.
• Desktop encryption scope truth: desktop project files remain explicitly documented as plaintext until the renderer-neutral R-15 storage work ships; the IndexedDB passphrase flow no longer presents itself as a project-file encryption gate on Tauri.
• CI authority closure: Core path changes now select the Tauri consumer gate, workflow-policy tests protect local path-dependency coverage and aggregate deployment gating, and Pages deployment waits for ci-success.
• Accessibility contrast: command-palette heading contrast was corrected to meet the intended WCAG threshold.

Deprecated

• storycraft:// deep links: the legacy scheme remains accepted for this release and displays a migration notice; it is scheduled for removal in the next release.

Changed

• CSP egress parity: Web/PWA and Tauri now use one explicit provider, local-service, and Yjs signaling origin allowlist; arbitrary HTTPS egress and the contradictory loopback upgrade policy are no longer accepted. New BYOK endpoints require an explicit CSP policy update.

• Qt Early Killer-Gate qualification: the native roadmap now requires cheap, evidence-backed lifecycle, accessibility/input, packaging/update-trust, crash/recovery, and security checks before substantial Qt UI work can create sunk cost.

• Diagnostics sink boundary: structured log construction and recursive redaction now remain portable before serialized IDB, Tauri JSONL, and development-console adapters receive the record; legacy logger APIs remain compatible and no sink authority switch is claimed.

• Coverage scope and threshold calibration: coverage now measures the root application/PWA shell; CI recalibrated floors to L80/F72/B66/S78 from the expanded-scope measurement, and the token audit baseline was ratcheted down from 160 to the verified current count of 159.

• Native desktop strategy: ADR-0021 adopts Qt 6/Qt Quick as the future primary native product, keeps React/PWA first-class, makes Tauri transitional, admits GPUI later behind a gate, and retires CEF from the target architecture.

• DesktopPlatform boundary: direct Tauri imports are mechanically constrained by the zero- tolerance guardrail while the renderer-neutral contract becomes the native transition surface.

• Diagnostics parity and task contracts: Rust/TypeScript wire-shape and redaction fixtures now cover the diagnostics boundary, and TaskSupervisor requests/results reject unsupported contract versions before native execution (#437, #439, #440).

• Native maturity evidence: the G1 qualification ledger now records the partial, evidence-backed status of the native migration without claiming a production authority switch (#438).

• Mutation-test plumbing: the manual Stryker workflow now uses explicit per-module incremental files, preserves module report identity, validates aggregate metrics, fails closed on missing shards, and propagates aggregation failures through the summary pipeline.

• Quality-gate truth: Vitest CI no longer retries the suite, the suppression ratchet was reduced from 52 to 48 through real test-mock cleanup, and docs checks now validate README test file/case metrics against the current Vitest source set.

Security

• CI supply-chain policy: CodeQL action references and token permissions were hardened and Dependabot grouping was corrected so related action paths move together.
• Diagnostics redaction: sensitive nested diagnostic context is recursively redacted before serialized IDB, Tauri JSONL, or development-console sinks receive it.

[1.27.1] — 2026-08-14

Desktop persistence/security stabilization (#363) — atomic writes and fail-closed key routing across every Tauri filesystem-backed store, a factory-reset UI/logic consolidation, and three new required CI gates (Rust compile/lint/test, E2E, Visual Regression) that previously let native-code and UI-regression risk merge unchecked — plus a nanoid security-advisory patch.

Fixed

• Atomic writes across all Tauri filesystem-backed stores (services/fs/{assetFsStore, codexFsStore,fsCore,projectFsStore,settingsFsStore,snapshotFsStore}.ts) — writes are now serialized, and an orphaned temp file left behind by a failed write is retried on cleanup (with a warning logged, not silently dropped) instead of risking corruption of concurrently-written project data.
• Unified, fail-closed desktop API-key routing. Desktop key storage now routes unconditionally through the same encrypted IndexedDB path used on the web, with recovery-reset hardened to fail closed rather than leaving a partially-wiped state; docs/SECURITY-THREAT-MODEL.md corrected to describe the unconditional routing and the best-effort (not guaranteed) nature of legacy-key-file cleanup.
• Factory reset / danger-zone UI consolidated. New hooks/useFactoryReset.ts + components/settings/FactoryResetDangerZone.tsx replace three near-duplicate confirm/wipe/error/ busy implementations across ApiKeySection, IdbUnlockModal, and EncryptionRecoveryModal; also fixes a bug where the stuck "recovery-required" branch had no error paragraph to render a failed reset's error state.
• Packaged-build factory reset was broken. The Tauri fs capability glob for fs:allow-exists and fs:allow-read-dir only covered $APPDATA/**, rejecting exists()/readDir() on the $APPDATA root itself; the capability now grants the exact root path too (src-tauri/capabilities/default.json).
• Corrupt binder-asset detection fixed. A binary/metadata byte-size mismatch is now treated as corruption instead of silently pairing two independent atomic writes from different save generations as if they were one transaction.
• Legacy API-key file cleanup no longer provider-list-bound. Scans the config directory by the *_key.enc.json naming convention instead of a hardcoded 5-provider list, so a future or unlisted provider's legacy key file is no longer left behind after migration.
• Rust: Builder::on_menu_event gated #[cfg(desktop)]. The call was unconditional despite the crate itself restricting that method to desktop, which would have failed to compile for the mobile targets src-tauri/src/lib.rs already anticipates (#[cfg_attr(mobile, ...)]).
• Re-wired the dead Rust menu-action event bridge. registerTauriMenuHandler is back as a pre-paint-window fallback, self-unregistering once the JS-owned menu (installDesktopMenu) takes over — the native fallback menu's items were previously silently inert, and the two menus can no longer double-dispatch a single click.

Security

• nanoid security advisory patched (PR #362) — nanoid@3.3.17 → 3.3.18, added to minimumReleaseAgeExclude in pnpm-workspace.yaml so the fix isn't held back by the 10,080-minute (7-day) minimumReleaseAge policy.

Changed

• CI: Rust compile/lint/test, E2E, and Visual Regression Testing are now required merge gates (rust-tauri, e2e, vrt join the ci-success aggregator's needs). Previously native Rust code and UI regressions could merge into main with no automated check beyond an advisory OSV vulnerability scan.

Tests

• Added coverage for the new clearTauriAppData branch and the factory-reset danger-zone UI (tests/unit/factoryResetService.test.ts, tests/unit/settings/{EncryptionRecoveryModal, IdbUnlockModal}.test.tsx, tests/unit/services/fs/{fsCore,fsStores}.test.ts, tests/unit/tauriServices.test.ts, tests/unit/ApiKeySection.test.tsx) — codecov/patch had dropped to 52.75% before this pass.

[1.27.0] — 2026-08-13

Added

• Durable encryption migration journal (services/storage/encryptionMigrationJournal.ts) — persisted, versioned, no-secret coordination metadata (phase, per-store checkpoints, a compare-and-swap owner lease) for cross-database at-rest encryption migrations, which cannot be wrapped in a single atomic IndexedDB transaction. Protected access is blocked while a migration is active or requires recovery, and a durable transaction prevents competing migration owners. This is a recovery foundation — see below for what still isn't wired to a production trigger. (#337)
• Resumable protected-store migration runner (protectedStoreMigration.ts) with registered adapters for the two secondary stores (scene revisions, AI inference cache): batch conversion, interruption/resume from the last durable checkpoint, and verification that distinguishes a genuine shortfall from records legitimately deleted by cache eviction or history retention. (#337)
• Cross-tab admission for protected writes vs. active migrations (services/storage/protectedWriteAdmission.ts) — a Web Locks API shared/exclusive lock closes the race where an ordinary protected write could commit after a migration had already claimed ownership of the same store, which could otherwise land ciphertext under a superseded key/generation. (#339)
• Manual "Reduce transparency effects" accessibility toggle (Settings › Accessibility, accessibility.reducedTransparency, default off) — strips backdrop-blur-* GPU compositing everywhere, for desktop/Linux users whose window manager doesn't expose the OS-level prefers-reduced-transparency preference that the existing automatic mitigation relies on. (#332)
• Downloaded/total size and speed in both model-download progress UIs (#333 item 1). VoiceModelDownloadModal now shows real byte counts and transfer speed, sourced directly from transformers.js's own progress payload (loaded/total fields it was already receiving but discarding). LocalAiDownloadProgress (WebLLM text models) shows an approximate downloaded/ total MB and speed, derived from the existing 0-1 progress fraction × a new per-model known-size table (WEBLLM_MODEL_APPROX_MB) — the installed @mlc-ai/web-llm's own progress callback exposes no structured byte counts, so this is clearly labeled as an estimate, not measured telemetry.
• Disabling at-rest encryption and rotating the storage passphrase are now live in Settings › Privacy — the production wiring the prior release's migration journal was built for. Both flows run through the same resumable, crash-recoverable migration journal, verify identity via a durable AES-GCM sentinel/verifier before touching any data, and surface an EncryptionRecoveryModal on next startup if a migration was interrupted mid-flight. Closes issue #338. (#342, #343)

Changed

• IndexedDB at-rest encryption now fails closed instead of silently downgrading to plaintext. Protected reads and writes are rejected with a typed locked-storage error whenever encryption is configured but the session key is missing, closing several Time-Of-Check-To-Time-Of-Use gaps where an intervening await (opening a transaction, awaiting encryption) could let Lock Session race a write into plaintext. Every previously-unguarded destructive/listing path (deleteImage, deleteBinderAsset, listBinderAssetIds, deleteStoryCodex, listSnapshots, deleteSnapshot, deleteProject) now has the same guard. At the time of this change, disabling encryption or rotating the passphrase was intentionally unavailable pending the migration journal's resumable conversion protocol being wired to a production trigger — see the "Added" section above for the production wiring that shipped in this same release. (#335)
• Desktop AI provider and Python integration hardening, addressing user-reported release-quality issues #332/#333: removed the brittle Gemini AIza-prefix key rejection in favor of minimal syntax checks plus real provider validation; Local AI cancel/retry now operates on the actual in-flight acquisition instead of a detached handle, and terminal failures stay visible instead of silently resetting to idle; LM Studio discovery/testing now uses the correct OpenAI-compatible /v1/models endpoint with sanitized diagnostics surfaced in the UI; desktop Python discovery, executable selection, and version/error reporting were centralized for consistency across commands. (#336)

Fixed

• Secure-record codec no longer silently corrupts unsupported structured-clone types. Map, Set, RegExp, and non-Uint8Array typed arrays previously fell through to a generic object-entries encoder that lost their type and often all content; they now fail closed instead of being encrypted as a different, wrong value. (#337)
• Encryption migration journal rejects illegal phase transitions — completing a migration from a freshly prepared journal (skipping conversion and verification entirely) is no longer possible; only a committing or cleanup phase may terminate. (#337)
• Migration verification no longer re-scans already-verified stores on resume, and a batch that reports progress without advancing its durable cursor is now rejected instead of being able to replay the same records indefinitely. (#337)
• Desktop (Tauri) build never read persisted state back at cold boot. The app's boot-time hydration called the raw IndexedDB-only dbService.loadState() unconditionally, with zero Tauri branching, while every save path already routed through the Tauri-aware storageService — every desktop launch loaded as a brand-new user regardless of what was actually saved to disk (a strict superset of the reported "appearance preference doesn't persist" symptom). Boot-time hydration (services/appBootstrap.ts) now mirrors the save path, branching on isTauriRuntime(). The first-ever-launch settings default (appearancePreset) is also reconciled between idbProjectStore.ts's normalizer and settingsSlice.ts's deliberate 'sepia' initial state, and quitting the desktop window now awaits any pending 1s-debounced project/settings autosave (services/desktop/desktopTray.ts) before the process actually exits, instead of allowing a quit to land mid-debounce and silently drop the last edit. (#332)
• SettingsView re-rendered its entire tree on every unrelated Redux state change — useSettingsView's return value was a fresh object every render (no memoization), so any background write anywhere in the app (autosave, AI copilot, progress tracker) forced every Settings component to re-render even while a completely different view was in the foreground. The context value is now memoized against its actual dependencies. (#332)
• AI Writing Studio manuscript text was unreadable, with selection/caret position drifting from the visible text. ContextPanel.tsx's real (input-handling) textarea sat invisibly over a separate visible text-mirror layer; the shared Textarea primitive's unconditional backdrop-blur-md blurred the mirror text underneath, the two layers resolved different concrete font stacks for the same font setting (different glyph metrics → position drift), and neither layer synced its scroll position with the other. components/manuscript/ManuscriptEditor.tsx (the primary writing surface) used the same fragile pattern and carried the same blur/scroll-sync defect. Fixed via a new Textarea variant="overlay" (no glass background/blur/reserved padding/mic button) and a single shared services/editorTypography.ts font-stack resolver used by both the real textarea and its mirror in both components, plus one-directional scroll sync from each real textarea to its mirror. (#341)
• Overlay-variant textareas dropped RTL font resolution, custom-font selection, and dictation. resolveEditorFontFamily now also takes the active text direction and settings.customFont?.name (previously every editorFont: 'custom' silently rendered as JetBrains Mono, and RTL sessions used LTR font stacks); the new DictationButton component restores the microphone entry point that variant="overlay" had unconditionally removed from both Writer Studio and the manuscript editor, rendered as a sibling above the mirror instead of inside Textarea itself. Also fixes two related scroll-sync gaps: the mirror now resets to the top on a section switch instead of showing a stale offset, and re-syncs after debounced/deferred content growth instead of staying clamped to a since-invalid scroll range. (#341, #344)
• Voice model download progress bar looked stuck at ~95% for most of the download. voiceCommandService.ts's download progress handler treated transformers.js's progress field as if it were already a 0-1 fraction; it's actually 0-100 (percent), so the existing Math.min(0.95, pct) safety clamp kicked in almost immediately (any progress value over 0.95%, i.e. after the very first chunk of the download) and stayed there until the download's final "complete" dispatch. Now derives the fraction from the payload's real loaded/total byte counts (falling back to progress / 100 only when those are absent). (#333 item 1)

Docs

• Closed out the PR #310 reconciliation ledger as superseded — #335/#336/#337 are merged into main, satisfying the one condition its merge decision previously left open. PR #310 itself was never merged; its own branch remained non-resumable throughout.
• Opened, then closed in this same release, issue #338 tracking the Phase-4 work: wiring the migration journal to a real disable/passphrase-rotation UI flow, primary IDB-store adapters, and the two above race-condition fixes' production reachability — all landed via #342/#343 (see "Added" above).

[1.26.0] — 2026-08-01

Added

• Opt-in native desktop notifications now report completed encrypted-library and manuscript exports, updater readiness, and ProForge stage completion through the Tauri notification plugin. Permission is requested only after the user enables the setting, web builds remain a no-op, and the settings migration defaults existing installations to disabled. (#306)

Changed

• Local-inference worker capacity now follows the detected memory tier: low-memory devices use one inference worker, the default remains two, and high-memory devices may use three. Detection failures safely retain the two-worker default. (#305)
• WorkerBus is now an authoritative, event-driven priority scheduler. Tasks dispatch only after leaving the bounded queue; worker availability events replace animation-frame polling; retries re-enter the scheduler without duplicating logical handles; and an eight-task critical reserve bounds total queue growth while retaining emergency capacity. (#307)

Fixed

• Worker tasks can no longer remain pending indefinitely after queue saturation or inactivity. The progress-rearmed inactivity watchdog now starts at enqueue, covers both queue wait and active execution, retries recoverable timeouts, and replaces presumed-wedged workers without returning them to the idle pool. Worker-construction, replacement, cancellation, retry-backpressure, shutdown, and pool-termination failures all settle through one cleanup path. (#305, #307)
• Completed tasks are removed from live scheduler state, so more than 32 lifetime submissions no longer trigger false BACKPRESSURE; priority order and FIFO-within-tier are preserved under saturation, and completed progress iterators terminate instead of hanging. (#307)
• The E2E API-key setup helper uses an exact configured-status match, avoiding strict-locator ambiguity between the status badge and its descriptive label. (#307)

Tests

• Added direct regressions for queue drain and reuse, priority ordering, critical reserve bounds, queued and active timeouts, fresh retry tokens, cancellation, shutdown, pool termination, constructor/replacement failures, listener/timer cleanup, and progress-iterator completion.

[1.25.0] — 2026-07-31

Added

• Grok (xAI) wired into the primary provider dropdown — the backend (streamGrok(), BYOK key storage, /v1/models connection test) already worked; it just wasn't reachable from AiProviderCard.tsx's main flow. Added the key input + model selector (grok-3/grok-3-mini), a providerToKind() case for the newer Vercel-AI-SDK layer, and fixed the whole provider array's i18n (several labels were hardcoded literals). See ADR-0016.
• Claude (Anthropic) now works on desktop — streamAnthropic() threw unconditionally on every platform; CORS is a browser-only restriction, so desktop now calls Anthropic directly via the same native-HTTP escape hatch ADR-0012 established for Ollama. Desktop Settings now shows a real key input + model selector (Opus 4.7/Sonnet 4.6/Haiku 4.5) instead of a warning-only block.
• Claude (Anthropic) now works on the web/PWA (Vercel, Cloudflare Pages) via a new stateless serverless proxy (api/claude-proxy.ts + functions/api/claude-proxy.ts) — this app's first backend dependency ever. Schema-validated, body-size-capped, same-origin-checked, rate-limited, and timeout-bounded; never logs the API key, prompt, or response. GitHub Pages (static-only, can't host the proxy) shows an honest "not available on this deployment" state instead of a silent failure. This is the one provider whose BYOK key transits WorldScript's own infrastructure in the web build — documented plainly in docs/SECURITY-THREAT-MODEL.md and README's privacy framing, not folded into the general "direct browser→provider" claim every other provider gets.
• Opt-in direct browser→Ollama connection in the web/PWA build (enableBrowserOllama, default off, Settings → Experimental) — for users who start their own Ollama server with OLLAMA_ORIGINS covering the page's exact origin, matching NovelCrafter's real (non-proxy) browser-Ollama model. Not a bypass and not the default: desktop remains the recommended, zero-config path. The Settings UI renders the exact OLLAMA_ORIGINS=<origin> ollama serve command for the current deployment. See ADR-0017 (Issue #266 follow-up).

Security

• DuckDB codex_mentions.excerpt — the one analytics column holding literal manuscript prose — is now cell-level encrypted (SEC-6) when enableIdbAtRestEncryption is active. duckdbCodexWrite() (services/duckdb/duckdbAnalytics.ts) encrypts new excerpts via services/duckdb/duckdbEncryption.ts (AES-256-GCM, reusing the IDB at-rest encryption key) into a new excerpt_enc BLOB column and nulls the plaintext excerpt column; a new backfill migration (services/duckdb/codexExcerptEncryptionMigration.ts) re-encrypts any pre-existing plaintext rows once encryption is unlocked, without blocking the schema's other migrations when encryption isn't active this session. Full OPFS file-level encryption remains infeasible — DuckDB-WASM owns the OPFS file handle directly, leaving no app-level interception point — so the other DuckDB metadata columns (title/logline/name/character_names/label) stay intentionally plaintext by design, not manuscript prose.
• SEC-6 backfill migration marker was a single global key, not scoped per project — once any project completed the excerpt-encryption backfill, every other project's plaintext codex_mentions.excerpt rows were silently never migrated. isCodexExcerptEncryptionMigrationDone() now takes a projectId and scopes the _meta done-marker key per project. Also fixed duckdbCodexWrite()'s ON CONFLICT clause for codex_mentions so an unencrypted write (a session where IDB encryption isn't unlocked yet) can no longer clobber an existing ciphertext row back to plaintext — it now preserves any prior excerpt_enc via COALESCE/CASE instead of overwriting it. Added a two-project regression test proving the marker-scoping fix and a test asserting the ON CONFLICT clause never downgrades ciphertext. (CodeRabbit + Copilot review, PR #303)
• A failed per-row UPDATE during the SEC-6 excerpt-encryption backfill could still let the migration write its done-marker — the row's plaintext excerpt would then never be retried or encrypted on any future run. runCodexExcerptEncryptionMigration() now tracks row-level failures (a failed UPDATE, or encryptDuckDbData() throwing) and skips the done-marker, returning { aborted: true } so the still-plaintext rows are retried next run instead of being silently left unencrypted forever. (CodeRabbit outside-diff-range finding, PR #303)

Fixed

• event-listener (Rust, transitive via Tauri) bumped 5.4.1 → 5.4.2 — the OSV/RUSTSEC scan flagged 5.4.1 as vulnerable (RUSTSEC-2026-0221), fixed upstream in 5.4.2; Cargo.lock only, no other dependency churn.
• Doc-drift gate (scripts/check-doc-metrics.mjs) had a blind spot for still-open checklist bullets inside dated/historical sections: stripHistoricalSections() blanked every line in a historical section indiscriminately, including a genuinely still-open - ⬜ bullet — exactly how a stale "Tag v1.24.2" bullet escaped the gate in a same-day doc edit (dc14bc0). OPEN_BULLET now gets the same "always present-tense, never stripped" treatment DONE_BULLET already had for the opposite polarity. scanForDrift() also gains a new check: a surviving open bullet mentioning tag/release/publish (including inflected forms — "Tagging"/"Releasing"/"Publishing") of a version <= the latest git tag is now flagged as drift. (#293)

Docs

• CLAUDE.md codifies three merge-discipline lessons learned during the PROMPT-WSS-v1.24.x recovery sprint: never commit directly to main (always branch + PR, even for a single-file change); wait for the full CI suite — including non-required/advisory jobs like E2E, Storybook, Lighthouse, and Visual Regression — to go green before merging, not just the branch-protection-required checks; and group related small workstreams into the fewest reviewable PRs by natural/documented boundaries rather than one PR per tiny item, while keeping one commit per logical concern. Also adds a "Known merge-gate quirks" section distinguishing GitHub's real pending-check block from this repo's own stricter wait-for-pass policy and the mergeable-state cache-lag symptom, plus documents the stacked-PR auto-close-on-squash-merge side effect and its recovery steps; and strengthens the CodeAnt Correction Loop policy to explicitly cover CodeRabbit's collapsed nitpick and outside-diff-range comment sections. (#294)
• .github/SECURITY.md / docs/SECURITY-THREAT-MODEL.md SEC-6 status corrected to reflect the DuckDB excerpt-encryption wiring above, and the Claude serverless proxy section gains an explicit monitoring recommendation (platform-native Vercel/Cloudflare request analytics — no in-app logging, which would violate the proxy's zero-console-call stateless guarantee).
• docs/history/GROK-PROVIDER-INTEGRATION-PLAN.md status header updated from "Plan only — do not implement yet" to reflect that all phases shipped; retained as the historical design record.
• TODO.md reworded the open tag/publish bullet so it no longer embeds the literal v1.25.0 version string on the - ⬜ bullet line itself, removing the risk that scripts/check-doc-metrics.mjs's scanForDrift() would flag it as stale drift once the v1.25.0 tag is actually pushed (verified via a scanForDrift() simulation with latestVersion: '1.25.0' — zero findings).
• docs/SECURITY-THREAT-MODEL.md now names the specific platform observability products (Vercel Function Logs / Vercel Observability; Cloudflare Workers Metrics/Analytics and Workers Logs) instead of a vague "platform-native analytics" reference, and notes that Cloudflare Workers Logs is opt-in and must be enabled via the Wrangler observability config.

Tests

• Closed 3 Codecov patch-coverage gaps found on PR #303: the DuckDB analytics migration listener in app/listenerMiddleware.ts was never exercised by any test at all (stale mocks — loadDuckdbMigration's mock returned runIfNeeded, but the real listener calls runMigrationWithRollback; loadRagVectorMigration's mock resolved undefined where the listener reads .aborted) — fixed the mocks and added 2 tests covering both branches of the codexEncResult.aborted gate. Added 5 tests for codexExcerptEncryptionMigration.ts (a post-loop privacy-gate abort distinct from the existing mid-loop-abort case, a failed row UPDATE that now aborts without writing the done-marker, a row-encryption throw that aborts the same way, and the migrated % 10 === 0 yield-point). Added a test for useDuckDb.ts's new v3 migration DDL failure branch.

[1.24.3] — 2026-07-30

Worker-generation consolidation sprint: the v1/WorkerBus-v2 duplication ADR-0014 deferred is now closed out. Executed as 5 stacked PRs (#286–288, #290–291), plus the independent #289 (Vercel auto-deploy pause); see ADR-0015 for the full decision record. This release also recovers a merge queue interrupted mid-session by a local editor crash — all five PRs required a fresh sync-merge conflict resolution against the accumulated fixes below before landing; see docs/audit/ for the run log.

Changed

• DuckDB analytics and local inference (embeddings + NLP) now route through WorkerBus v2, replacing dedicated new Worker(...) instances per service. services/duckdb/duckdbClient.ts, services/ai/localEmbeddingService.ts, and services/ai/localNlpService.ts keep their exact public APIs — an adapter pattern, not a consumer rewrite, so none of their real callers needed changes. ensureDuckDbPool()/ensureInferencePool() added to services/workerBusManager.ts, decoupled from enableWorkerBusV2 (mirrors the existing ensureWebLlmPool() pattern — these are core features, not experimental infra).
• The shared inference WorkerBus pool's maxWorkers capped at 2 (was 4) — each replica independently loads its own transformers.js pipeline with no cross-replica cache sharing, so 4 concurrent workers under a burst could mean 4x the model memory footprint.
• Vercel auto-deploy paused mid-term after 2 consecutive preview-deployment failures with only a generic "Deployment has failed" message and no reproducing local failure — GitHub Pages and Cloudflare Pages remain live and unaffected while the platform-side cause is investigated.

Fixed

• DuckDB query/exec parameters were silently dropped, executing an unbound query — already live and breaking services/ai/telemetryService.ts's parameterized INSERT writes. Fixed via DuckDB-WASM prepared statements.
• WorkerBus.terminatePool() could leave tasks hanging forever — removing a pool didn't settle tasks already routed to it. Fixed by tracking task→pool assignment and cancelling matching tasks before removal; a pool removed this way is now also transparently re-registered on next use instead of failing every subsequent call.
• A respawned DuckDB worker lost its connection, failing every query after an idle timeout with "DuckDB not initialized." Fixed by transparently re-initializing once and retrying.
• DuckDB's OPFS-unavailable fallback silently swallowed the failure, giving users no warning their analytics wouldn't persist across reloads (private browsing, old Safari) — restored via the existing progress channel. A follow-up fix made the fallback's own cleanup step best-effort, so a secondary failure there can no longer block the fallback path itself.
• A missing ensureInferencePool export broke production builds on Vercel (rolldown's [MISSING_EXPORT]) — not caught by Vitest (the consumer test mocks the whole module) or by local tsgo typecheck. Root-caused by reproducing Vercel's exact build command (pnpm run build:edge, which differs from the plain pnpm run build used for an earlier, misleading local repro attempt) and fixed by adding the missing function.
• A reused AbortSignal leaked one 'abort' listener per call in duckdbClient.ts's send() — {once: true} only self-removes once the signal actually fires, so a caller reusing one signal across many non-aborted queries (a common hook/thunk pattern) accumulated listeners for the signal's whole lifetime. Fixed with an explicit finally-block removeEventListener.
• ensureDuckDbPool()/ensureInferencePool() could reject instead of degrading gracefully — their pool re-registration helpers awaited a lazy import and called registerPool() without a catch, so a re-registration failure after the bus was already live broke the documented "returns null only if init failed" contract. Both now log the failure and return the live bus instead of propagating the rejection.

Removed

• workers/duckdbWorker.ts and workers/inference.worker.ts (the v1 worker generation) — both workloads now exclusively use workers/v2/duckdb.worker.ts and workers/v2/inference.worker.ts.

[1.24.2] — 2026-07-29

CSP functional-truth, desktop crypto, and documentation-truth hardening sprint (PROMPT-WSS-v1.24.x). Headline fix: script-src shipped without 'wasm-unsafe-eval' for two months (2026-05-27 → 2026-07-29), silently blocking WebAssembly.instantiate in every deployed Chromium browser — the entire advertised local-inference stack (WebLLM, ONNX Runtime Web, Transformers.js, DuckDB-WASM, Whisper-STT, Kokoro-TTS) never functioned in production. No gate caught it because the only CSP tests that existed checked cross-surface consistency, never functional correctness. See docs/adr/0013-csp-wasm-and-blob-frames.md and docs/audit/WS-RUN-LOG-2026-07-29.md for the full record.

Security

• F-01/F-02 — CSP functional truth. 'wasm-unsafe-eval' (never the broader 'unsafe-eval') and frame-src 'self' blob: added to all 5 deployment surfaces (index.html, vercel.json, public/_headers, nginx.conf ×3, src-tauri/tauri.conf.json). The unhashed inline aurora-disabled script that shipped alongside the broken CSP moved into index.tsx as a same-origin module. New 3-layer test architecture (tests/unit/cspCorrectness.test.ts + a hardened scripts/smoke-prod-build.mjs with real CSP-violation and WASM-instantiate probes) so this class of defect can't silently recur.
• F-05/F-06 — desktop API-key encryption. services/fs/fsCore.ts's key derivation used a single unsalted SHA-256 digest of publicly-derivable material — fixed to PBKDF2 (600,000 iterations) + a random 32-byte salt, matching the existing storageEncryptionService.ts pattern. Pre-existing key files are discarded (not migrated) with a one-time notification prompting re-entry. Correction (2026-08-13): this hardened the KDF against rainbow-table and multi-target reuse, but the derivation input itself — ${appDataPath}|${provider}|WorldScriptStudio|v1 — remained fully public/reconstructible, so the root "obfuscation, not encryption" finding was never actually closed. Tracked as an open gap — see docs/IDB-ENCRYPTION.md § Tauri Desktop Layer and AUDIT.md's F-05/F-06 row for current status. Review-loop follow-up (2026-08-13): docs/SECURITY-THREAT-MODEL.md's Desktop Local File-Read Attack Tree and document header still called this "fixed" and said reading the ciphertext no longer reveals the key material, directly contradicting the corrected Mitigation Mapping row above it — reconciled to say "not resolved" consistently throughout. Also documented a separate, unrelated functional bug surfaced while fact-checking this row: components/ApiKeySection.tsx never adopted the storageService/ FsSettingsStore path this desktop API-key row describes — it still reads/writes the Gemini key through dbService (IndexedDB) even on desktop, while services/geminiService.ts reads through storageService (filesystem on desktop), so a Gemini key saved via Settings → AI on desktop is invisible to the code that actually uses it. Tracked in #358; not fixed by this entry. Second review-loop follow-up (2026-08-13): tightened the attacker-capability wording (needs both the ciphertext and the public derivation inputs, not the ciphertext alone) in both the Mitigation Mapping row and the attack tree; added the same Gemini-exception note to the attack tree (previously only in the table row); and added a new Mitigation Mapping row for desktop project/settings/snapshot/Codex/RAG/image/binder-asset data, which this threat model previously didn't mention at all despite it having neither confidentiality nor authentication on disk — real fix in progress on PR #356.
• F-08 — Tauri/web connect-src completeness. Added LanguageTool's default self-hosted port (missing on all 5 surfaces, not just Tauri) and the Hugging Face hosts WebLLM/Transformers.js actually resolve models from, including the Xet CDN bridge (us.aws.cdn.hf.co) that real model weight downloads redirect to — traced empirically, not assumed.
• F-09 — DuckDB-WASM self-hosted. Replaced an unversioned, unreachable (already CSP-dead) third-party CDN with assets copied from the pinned @duckdb/duckdb-wasm npm dependency at build time (scripts/copy-duckdb-assets.mjs), never committed to git.

Fixed

• F-07 — doc truth-up. README/CLAUDE.md no longer make a blanket "encrypted at rest" claim; a fabricated tauri-plugin-stronghold reference (no trace of that dependency anywhere in the repo) removed and replaced with the actual mechanism per platform.
• F-10 — canonical production URL unified. A dead preview-deployment domain (worldscript-studio-indol.vercel.app, confirmed 404) had drifted into the in-app link and the Italian locale; both now reference a single PRODUCTION_URL constant. New drift gate in scripts/check-doc-metrics.mjs.
• F-12 — CI Storybook deduplication + a genuine broken test-runner invocation. Storybook was built 3× per CI run; deduped to 1×. While evaluating whether the Storybook test-runner's || true could be made blocking, found the invocation was calling flags (--max-workers/--retries/--screenshot-on-failure) the installed CLI version doesn't support — every prior run failed on argument parsing before executing a single story, silently turned green by || true. Fixed the invocation and moved the non-blocking behavior to step-level continue-on-error: true, which still surfaces genuine failures in the Actions UI.
• F-13 — coverage ratchet raised to CI-measured values (L79/F72/B65/S77, from L74/F67/B60/S72).
• Pre-existing a11y color-contrast failure (out of scope, fixed proactively). The CI a11y E2E gate caught WriterViewUI.tsx's Writer/ProForge version-control and Focus Mode toggles using --sc-accent-derived text on a tinted --sc-accent background — 4.47:1 on the sepia theme, below WCAG AA's 4.5:1. All 4 occurrences (2 desktop, 2 mobile, across two different broken token combos) now use the pre-vetted --nav-background-active/--nav-text-active pair already used for nav active-states elsewhere.

Documentation

• F-04 — CSP gate governance. docs/CI.md gains a "which layer catches which failure class" table and a post-mortem on why cross-surface-consistency tests alone were never sufficient.
• F-14 — worker-generation duplication documented (docs/adr/0014-worker-generation-duplication.md). Both a v1 and a WorkerBus-v2 generation of the DuckDB and local-inference workers are live via real call chains; consolidating them is a properly-scoped migration effort of its own, tracked but out of scope for this sprint.

[1.24.1] — 2026-07-28

Local-AI reliability (desktop Ollama/LM Studio/vLLM discovery, misleading browser status badge), the AI heuristic-fallback foundation + Outline/Character/World/Plot-Board generators, real self-hosted LanguageTool integration, a 20-PR Dependabot backlog triage (16 merged directly, 4 closed as superseded after the AI SDK v4 family/biome 2.5.x/dev-tooling-Babel-8 blockers were root-caused and fixed), the Issue #60 vendor-fork audit closeout, and security/build hardening (persist-credentials CWE-522, ltr/rtl Tailwind fix, 3 ineffective dynamic imports, 2 CWE-209 fixes).

Added

• Heuristic fallback for Plot-Board "suggest next beat". Completes offline coverage of the structured generators: when AI is unavailable, the Plot Board now offers localized, framework-based next-move suggestions (raise the stakes / introduce a complication / add a reversal) with rationale, instead of an error. See docs/AI-HEURISTIC-FALLBACKS.md.

• Heuristic fallback for Character & World profiles. When AI is unavailable, the Character and World generators now produce a schema-valid, localized starting profile (structured fields with the user's concept woven in; empty timeline/locations for World) instead of an error toast — extending the offline heuristic coverage to two more structured generators. Same pure-generator + hook-resolved-labels pattern as the Outline fallback. See docs/AI-HEURISTIC-FALLBACKS.md.

• Heuristic fallback for the Outline Generator. The first per-feature heuristic on the fallback foundation: when AI is unavailable the outline generator now produces a structurally-sound, schema-valid chapter skeleton — a three-act beat sheet scaled to the requested chapter count (setup → inciting incident → rising action / midpoint / complications → optional twist → climax → resolution) with the user's idea woven in — instead of just showing an error. Fully offline and localized (the hook resolves outline.heuristic.* labels; the generator stays pure). See docs/AI-HEURISTIC-FALLBACKS.md.

• AI heuristic-fallback foundation. Groundwork so AI features can degrade gracefully (offline, quota, error, Eco/Heuristics-only mode) instead of hard-failing. A pluggable heuristic-generator registry (services/ai/heuristicFallback/, modeled on the Copilot rule engine) + a shared HeuristicFallbackResult envelope (reuses ProForge's isFallback + a calibrated confidence), wired into the provider choke points that previously had no degrade path — generateText's terminal, generateJson (Gemini-direct), and streamText. A useHeuristicFallback() hook + reusable AssistedModeBadge surface the "Assisted (offline)" state and record fallbacks to telemetry. Ships inert (no per-feature generators yet → unchanged behavior); see ADR 0011. Per-feature generators (Outline/Character/World, Writing Studio tools, analysis tools) land in follow-up PRs.

• Real LanguageTool grammar & spelling integration (self-hosted, privacy-first). Replaces the hardcoded fake-typo list with a real, multilingual proofreader running on the user's own machine. Two surfaces share one offset-safe apply path (hooks/useLanguageToolCheck.ts): an on-demand "Check this scene" panel in the Writer tools sidebar (findings list → apply / ignore / add-to-dictionary) and a live inline overlay in the manuscript editor (debounced underline + suggestion popover, reusing the existing aligned-overlay infrastructure). New services/languageToolService.ts (checkText → parse matches[], text-hash cache, abortable, silent offline degrade, never logs text); the privacy gate (assertLanguageToolAllowed) keeps cloud servers blocked under local-only mode. Locale coverage is encoded in the SSOT i18n/locales.ts (languageToolSupport + languageToolCode, verified against dev.languagetool.org) and the feature is hidden for unsupported locales (tr/he/fi/hu/is/eu/ko). Opt-in via Settings → Connections; run a server with docker run -p 8010:8010 erikvl87/languagetool. See docs/LANGUAGETOOL.md and ADR 0010.

• Native Intel-Mac (x86_64) desktop builds — added, then reverted within this release. tauri-build.yml briefly added macos-13 (Intel) to the build matrix alongside macos-latest (Apple Silicon). In practice the macos-13 hosted runner never provisions: the job sits in GitHub's queue indefinitely instead of starting, so its own timeout-minutes: 45 never applies — and because the release job's needs: [bundle] only resolves once every matrix leg reaches a terminal state, this blocked the entire release for the full ~24h GitHub Actions queue ceiling even though Ubuntu/Windows/macOS-ARM finished in ~12 minutes. Removed macos-13 from the matrix; Intel Mac builds are tracked as a re-opened follow-up in TODO.md pending a working Intel runner option. The latest.json generator's per-arch warning / hard-fail-only-if-no-arch-signs logic (added alongside the original matrix change) is unaffected and already tolerates the missing arch. See docs/TAURI-CI.md.

• New Help article — "AI execution modes & OpenRouter". Documents the four live-switchable execution modes (Hybrid / Cloud / Local / Eco) and OpenRouter's free tier + circuit breaker (4×429 → 5 min pause, RPM tracking), which shipped without a Help entry. Added to the AI Studio help category, deep-linking to Settings; translated into the five Production locales, English fallback for the other 14 (per the tag-dense-HTML help-body policy).

• DeepSource static-analysis integration (token-free). Added .deepsource.toml (analysis-only — no autofix transformers, so it never fights Biome and needs no repo token; activates once the free DeepSource OSS app is installed). Auto-detects JavaScript/Rust/Docker/CSS analyzers. Complements the existing CI gate as a second review layer while CodeAnt's free-tier quota is exhausted. Process: docs/DEEPSOURCE-REVIEW-LOOP.md (living runbook, complements the CodeAnt one); backlog tracking: docs/DEEPSOURCE-REMEDIATION-PLAN.md (prioritised P0-security→P5-docs, with the triage principle: rule-ignore findings already governed by Biome/strict-TS/test convention, fix DeepSource-unique real issues).

Changed

• AI SDK family upgraded to v4/v7 (ai 6→7, @ai-sdk/google/@ai-sdk/openai/@ai-sdk/react 3→4). Bumped as one coordinated unit rather than merging the four Dependabot PRs individually — @ai-sdk/google@4 emits the new LanguageModelV4 spec, which the ai package's LanguageModel type only recognizes from v7 onward, so upgrading @ai-sdk/google alone (as Dependabot's #255 proposed) left services/ai/providerFactory.ts with a real tsc error. No application code changes were needed beyond the version bump — streamText/toTextStreamResponse/onFinish's usage shape in services/ai/worldScriptCompletionFetch.ts and createLanguageModelForWorldScript's LanguageModel return type in services/ai/providerFactory.ts are unaffected. Verified with pnpm run typecheck, pnpm run lint, and the full AI-provider/completion-fetch test suites (all passing).

• Biome upgraded to 2.5.4 (from 2.4.16), migrated cleanly. Two new rules the version enables required real fixes, not suppressions: lint/correctness/noUnsafeOptionalChaining (4 test files — (x?.[n] as T).prop-style patterns split into a separate variable assignment so an optional-chain short-circuit can no longer throw at the point of use) and lint/suspicious/noUndeclaredEnvVars (16 environment variables used across scripts/config/tests weren't declared in turbo.json's globalEnv, so Turborepo's cache correctness couldn't account for them — now declared). Also ran biome migrate for the linter.rules.recommended → linter.rules.preset config rename ahead of Biome's next major version.

• Settings hygiene. Removed stale Experimental-category search hints (plot board, codex, cross project — retired/promoted flags) in favor of current features; ProForgeDashboard now uses the catalog-driven MaturityBadge instead of a hard-coded Experimental pill, keeping the v1.24 maturity-label convention consistent.

• Desktop settings "minimize to tray" is now a proper switch. DesktopSection used the only raw <input type="checkbox"> left in Settings, with its hint not programmatically associated. It now renders the design-system ToggleSwitch (role="switch", aria-labelledby + aria-describedby hint, focus-visible ring, RTL-aware), matching every other Settings control — consistent styling and screen-reader behaviour. Added a DesktopSection component test (web no-op, accessible switch, state reflection, dispatch on toggle).

• Help content truthfulness pass (post-release). Two stale Help articles were corrected against code reality: Languages now states the real 19 interface languages with their Production / Near-Production / Beta status tiers + the quality dashboard (was "seven languages — German, English, French, Spanish, Italian, plus Arabic and Hebrew"); Feature flags now states 22 flags (16 default-on / 6 opt-in), explains the grouped-by-maturity Experimental UI with dependency-aware disabling, and drops the bullet for the removed enableWebnnInference flag (the WebNN execution provider is still described as an adaptive-engine backend). Refreshed in the five Production locales.

• ProForge is now opt-in (default off). The experimental 8-stage agentic editing pipeline (enableProForge) shipped on by default; it is token-heavy and carries loop risk, so it is now a user opt-in like Voice and the Global Copilot. New installs get 16 default-on / 6 default-off flags. Existing users who enabled or relied on it are unaffected (the persisted value wins); everyone can still turn it on under Settings → Experimental.

• Settings → Experimental features are grouped by category (Writing, AI, Editing Pipeline, Performance, Voice, …) with maturity + risk hints, dependency-aware disabling (a flag whose prerequisite is off — e.g. Voice WASM without Voice Support — is disabled with an explanation), a "Desktop app only" note for Rust Compute, and a Reset to defaults action.

• Voice-nightly annotation cleanup. The informational voice-nightly.yml real-Whisper job no longer surfaces a red "Process completed with exit code 1" annotation when the HF-CDN model download times out (a known transient). The download step is now step-level continue-on-error with a bounded 2-attempt retry, and a summary step writes the pass/fail signal to $GITHUB_STEP_SUMMARY, so the nightly signal is preserved without the misleading error annotation.

Fixed

• pnpm run build warnings: invalid [dir:ltr]/[dir:rtl] Tailwind arbitrary variants and 3 ineffective dynamic imports. ToggleSwitch's thumb translate used a malformed custom variant ([dir:ltr]:translate-x-5 [dir:rtl]:-translate-x-5) that Tailwind compiled to the invalid CSS pseudo-class :is(dir:ltr) (lightningcss minify warning on every production build) — replaced with Tailwind's built-in ltr:/rtl: direction variants, which correctly target the dir attribute App.tsx already sets on <html>. Separately, Rolldown flagged 3 dynamic import() calls (app/transientUiStore.ts, services/ai/ecoModeService.ts, services/spotlightTour.ts) as unable to move their module into a separate chunk because each was also statically imported elsewhere in the eager bundle — converted all three call sites to plain static imports, removing the dead-weight async indirection with no bundle-size change.

• PR #274 review findings that failed to post inline (CodeRabbit/GitHub API error). A rate-limited re-review posted its 10 findings as review-body text instead of inline comments; the 2 that did post (missing persist-credentials: false) were already fixed. Of the 7 that only existed in the review body text: AiProviderCard's status badge now has role="status" aria-live="polite"; a stale in-flight connection-test result (CWE-209) could overwrite testError after switching to Ollama-in-browser — added a monotonic request-id guard in handleTest and gated the action-row error span with the same !ollamaUntestable check the paragraph above it already used; ollamaService.ts's plugin_unavailable branch returned LocalServerError.message directly (a public class whose message isn't guaranteed safe for every kind) — now builds its own fixed safe string, matching the timeout/unreachable branches; and a scan-endpoint test asserted a loose /models substring instead of the exact /v1/models path. The remaining findings (missing // QNBS-v3: comments on several already-commented files/lines; services/CLAUDE.md's LanguageTool wording) were verified already covered by existing file-level rationale comments or already fixed in an earlier commit — not re-applied to avoid redundant/stale documentation.

• Ollama / LM Studio / vLLM discovery & connectivity on desktop, CORS noise in the PWA (#266). Root cause: all local-server traffic (services/ollamaService.ts, scanLocalOpenAiCompatibleEndpoints()) used the WebView's fetch, so inside the Tauri shell the cross-origin localhost requests died on CORS/PNA, and in the PWA the settings auto-effect probed localhost:11434 on every visit (loud CORS console errors). All local-server calls now go through the new thin services/localServerHttp.ts, which routes via @tauri-apps/plugin-http (native, CORS-free) on desktop and keeps browser fetch on the web, with shared URL normalization, timeout composition and unreachable/timeout classification (user aborts still propagate unchanged). The Settings → AI card no longer auto-probes localhost in the PWA — it shows a quiet "desktop app required" banner with a download CTA instead — and the desktop scan gained per-endpoint status badges (reachable / no response / timeout / HTTP error) plus a one-click Use this URL action. All new strings localized in 19 locales. See ADR 0012 and docs/LOCAL-AI.md.

• Desktop Ollama/LM Studio/vLLM discovery still broken in packaged builds after #269 (#266). Root cause: vite.config.ts's rollupOptions.external unconditionally externalized every @tauri-apps/* package from every vite build, including the exact build Tauri's beforeBuildCommand invokes to produce the .deb/.msi. Since services/localServerHttp.ts's @tauri-apps/plugin-http import is dynamic, this left an unresolvable bare module specifier in the shipped desktop bundle — every caller's catch classified the resulting load failure identically to a genuinely-down server (no CORS noise, no discovery, even with Ollama/LM Studio running). tauri dev was unaffected (Vite's dev server doesn't apply rollupOptions), so the regression only surfaced in packaged builds. Fixed by extracting the existing Tauri-build detection (resolveViteBase.ts's TAURI_ENV_PLATFORM/TAURI_PLATFORM check) into a shared isTauriBuild() export and making the external array conditional on it; the web/PWA build is unaffected. localServerHttp.ts's resolveFetch() also now classifies a plugin load failure as a distinct LocalServerError('plugin_unavailable') (logged), instead of folding it into 'unreachable'. See the 2026-07-28 update in ADR 0012.

• Misleading "Ready" status badge for Ollama in the browser (#266). The generic connection-status badge in AiProviderCard and the "desktop app required" banner were driven by two independent, never-reconciled state signals — testStatus (defaults to idle → "Ready"/"Bereit") and isDesktop. Since the auto-test effect and the manual "Test connection" button are both disabled for Ollama in a browser, testStatus could never leave its idle default there, so the badge always read "Ready" right next to a banner saying the opposite. It now shows a distinct "Not available in browser" label instead whenever provider === 'ollama' && !isDesktop, localized in all 19 locales; desktop is unaffected. Also: scanLocalOpenAiCompatibleEndpoints() now tries Ollama's native /api/tags first, falling back to the OpenAI-compat /v1/models shim only on failure (mirrors testOllamaConnection/listOllamaModels's existing native-first approach), so an older Ollama install without the compat shim isn't missed by the scan.

• Feature-catalog / slice default drift made structurally impossible. features/featureCatalog.ts now covers all 22 flags (was 16) and derives each entry's defaultOn from the slice's defaultFeatureFlagsState instead of hand-keying it — the class of bug where the catalog said false while the slice said true for ~12 flags can no longer recur (guarded by the new tests/unit/featureCatalog.test.ts). Added risk-level / desktop-requirement / dependency metadata.

Security

• GitHub Actions workflows drop persisted checkout credentials (CWE-522, zizmor/CodeRabbit). actions/checkout leaves the GITHUB_TOKEN in the local git config by default so later steps can push; none of the jobs across ci.yml (8 checkout steps), codeql.yml, docker.yml, mutation.yml, storybook-debug.yml, tauri-build.yml, or voice-nightly.yml push or commit after cloning, so the token had no reason to persist beyond the checkout step. All 14 checkout steps now set persist-credentials: false.
• @babel/core security override bounded to the 7.x line, fixing a broken Storybook build. The pnpm-workspace.yaml override for GHSA-4x5r-pxfx-6jf8 (>=7.29.6) had no upper bound, unlike every sibling override in the same block. When Babel 8.0.1 was published, pnpm resolved it for every consumer — including react-docgen@8.0.3 (via the Storybook toolchain), which declares its own "@babel/core": "^7.28.0" and calls the synchronous loadPartialConfig(), removed in Babel 8 in favor of loadPartialConfigSync(). This crashed every Storybook build (Error: Starting from Babel 8.0.0, the 'loadPartialConfig' function expects a callback). Bounded to >=7.29.6 <8, matching the pattern the undici override right below it already documents for the identical failure class. Verified: pnpm run build-storybook completes successfully again.
• Tauri HTTP-plugin capability scope pinned (#266). http:default alone grants no URL scope — every plugin-http call (including AI-SDK cloud calls on desktop) was silently denied by the plugin's allow-list check. The capability now explicitly allows loopback any-port (http://localhost:*/*, http://127.0.0.1:*/* — Ollama/LM Studio/vLLM + custom ports) and the cloud endpoints mirroring the Tauri CSP connect-src (Gemini, OpenAI, x.ai, OpenRouter, Groq).
• y-webrtc vendor-fork audit + CI invariant guard (#60). Full-file diff of packages/collab-transport against upstream y-webrtc@10.3.0: no deviations beyond the three documented SC patches (PBKDF2 600k iterations, extractable: false, return promise.reject) plus the DataChannel E2E encryption — recorded in packages/collab-transport/AUDIT.md, fork bumped to 10.3.0-sc2. The deprecated patches/y-webrtc@10.3.0.patch and the dead root y-webrtc dependency (zero imports) are removed, and the previously-referenced-but-missing scripts/verify-vendor-fork.mjs now exists and runs in the CI security job (verify:vendor).
• Advisory batch remediated (2026-07-26, CI security gate). Cargo.lock: quick-xml 0.39.4 → 0.41.0 via plist 1.10.0 (RUSTSEC-2026-0194/0195, CVSS 7.5), anyhow → 1.0.104, crossbeam-epoch → 0.9.20, serde_with → 3.21.0. pnpm overrides raised: dompurify → 3.4.12, protobufjs → 8.7.1, body-parser → 1.20.6 (bounded <2 for express-4 compat). The two stale no-longer-matching OSV ignores (dompurify GHSA-x4vx-rjvf-j5p4, js-yaml-3.x GHSA-h67p-54hq-rp68) were dropped from src-tauri/osv-scanner.toml. The pnpm audit CI step is now advisory (continue-on-error): some npm CDN edge nodes force-gzip the bulk-advisories response which pnpm cannot decode (ERR_PNPM_AUDIT_BAD_RESPONSE, deterministic per edge — retries useless); the OSV scan of both lockfiles remains the enforced gate.

Removed

• Dead enableWebnnInference feature flag removed. The flag shipped default-on but no runtime gate ever read selectEnableWebnnInference — toggling it had no observable effect (a ghost/stub, flagged by audit-feature-parity.ts). It is removed from the slice, featureCatalog, the Settings → Experimental UI (now 22 flags / 21 user-toggleable), the i18n label (19 locales) and the parity audit. WebNN execution-provider selection remains available internally in packages/ai-core/src/webnnBridge.ts (always attempted when the browser exposes WebNN); only the no-op user toggle is gone.
• Dead Settings toggles removed (19 no-op toggles across 6 sections). A full audit found settings that persisted a value no service or hook ever read. Removed the whole Notifications, Performance, and Backup sections (all no-ops; the real one-click encrypted backup lives in Settings → Data, untouched), the dead sync/import card in Integrations (Notion/Evernote/Google Docs/Scrivener — the LanguageTool integration is real and kept), the 4 dead Collaboration toggles (the WebRTC signaling URLs field is real and kept), and Privacy's crashReporting / shareUsageData (analytics/encryption/data-residency stay). Also cleaned settingsSearchHints.ts (stale hints for the removed categories; retargeted Integrations hints to grammar/spell). Each was a stacked PR with its own tests + i18n removal across 19 locales.

[1.24.0] — 2026-06-21

Critical & Immediate hardening sequence — six stacked PRs (privacy, experimental labeling, coverage, voice consent, local-AI, hygiene/docs) plus the 11→17 locale expansion, shipped as a minor release.

Security

• Privacy → Analytics is now a real opt-out (SEC-6). The Settings → Privacy "Analytics" toggle was cosmetic — only the enableDuckDbAnalytics flag controlled persistence. A single enforcement point (app/analyticsGate.ts isAnalyticsPersistenceAllowed) now gates every DuckDB write path (project dual-write, codex, cross-project mirror, RAG vector mirror, seed + RAG migrations, and inference telemetry) on both the flag and the privacy toggle. The gate is re-evaluated at the last synchronous moment before each async write (no opt-out race); migrations abort without writing their done-marker (so re-opt-in retries) and recover from a transient error state; a one-time analyticsGateMigrated marker preserves existing-install behavior on upgrade. Analytics remain local-only metadata (never manuscript prose, never leaves the device). Full DuckDB OPFS/cell encryption stays deferred to v2.0 (docs/SECURITY-THREAT-MODEL.md).
• Voice consent clarity. Corrected the misleading "all voice processing runs locally" intro (the default STT path is the cloud Web Speech API) and added a per-engine cloud-vs-on-device privacy note beside the STT engine selector (settings.voice.engine.privacyNote, 17 locales).

Added

• Device-aware Ollama recommendation + one-click pull. pullOllamaModel streams POST /api/pull progress with cancel + error-retry (surfaces Ollama's in-band {error} lines, propagates AbortError for cancel, releases the reader on every path); getOllamaModelForDevice picks a tiered model (qwen2.5:7b / llama3.2:3b / llama3.2:1b) from the device profile and steps down a size on low battery; new OllamaDevicePull settings UI with a recommendation chip + progress/cancel/retry.
• Reusable Badge design-system atom (variant experimental | beta | new | neutral, theme-token driven, accessible) with a Storybook story; applied as maturity badges (driven by FEATURE_CATALOG) in the Experimental flags list and an "Experimental" badge in the ProForge dashboard header. New "Limitations, Token Cost & Loop Risks" section in docs/PROFORGE-PIPELINE.md.
• Test coverage for newer subsystems (+101 tests): collab-transport E2E crypto (the vendored y-webrtc C-1 fork), the ProForge Core Capability Layer + adapters (proForgeCapabilityCore, schemas, agentRegistry, nodeInferenceGateway, browserProForgeCapability), and the 5 previously-untested Copilot components (CopilotPanel, CopilotLauncher, InlineAnnotationLayer, InsightSection, HeuristicsModeToggle).
• Language expansion — 6 new locales (11 → 17): Finnish (fi), Swedish (sv), Hungarian (hu), Icelandic (is), Basque (eu) and Persian/Farsi (fa, RTL, Arabic script). All ship as Beta. The high-traffic chrome (portal, sidebar, dashboard, top common.* verbs) plus native cold-start strings (i18nBootstrap) and glossary blocks are hand-translated; the remaining modules were then completed via the glossary-anchored bulk translator (see the bulk-translation entry below). fa direction/fonts are automatic via RTL_LOCALES + the existing [dir="rtl"] Noto Arabic swap — no App/CSS/font changes. New guide: docs/LANGUAGE-EXPANSION-2026.md.
• Bulk-translate hardening (scripts/bulk-translate-locales.mjs): placeholder masking ({{token}} → sentinel → restore, so MT can't mangle interpolation) and a --dry-run mode (per-file key + glossary-hit counts, no network calls, no writes). The 6 new languages are added to SUPPORTED_LANGS, check-i18n-keys.mjs, and build-i18n.mjs. The i18nPlaceholders guard now covers all 17 locale bundles.
• Localized language picker: LanguageSelector now resolves each language's exonym label (e.g. "Finnish", "Swedish") through t('portal.language.names.<code>') at render time instead of a hardcoded string — the native endonym (Suomi, Svenska, …) stays hardcoded by design so users always find their own language regardless of the active UI locale. Adds portal.language.names.* (17 names) to all 17 locales, hand-translated for the 5 core + 6 new languages (other Beta locales' exonyms filled by the bulk translator). portal chrome is now fully localized for the 6 new languages.
• Beta-locale bulk translation (10 languages): ran the glossary-anchored, placeholder-masked bulk-translate-locales.mjs pipeline for fi/sv/hu/is/eu/fa (full) and topped up ja/zh/pt/el, lifting the 6 new locales from ~8 % to 90-93 % coverage (machine-translated, Beta quality, human native review tracked as follow-up). help.json (long-form rich HTML) stays English fallback for the new langs and is excluded from --all — its tag-dense markup is not safely machine-translatable. Glossary expanded to v2.0 (~44 anchor terms/locale: + Co-Pilot, ProForge, Subplot, Timeline, Snapshot, Synopsis, Mind Map, Word Count, Continue Writing, Improve Writing, Consistency Checker, Plot Hole, …). Two bulk-script bugs fixed: glossaryTranslate partial-match (→ exact-match only) and --all mangling help.json HTML (→ excluded).
• New docs/TRANSLATION-GUIDE.md: end-to-end localization guide — architecture/build flow, placeholder/token rules, tone-by-category, RTL guidelines + per-locale verification checklist, glossary usage, native-review checklist, common pitfalls, and the new-language contribution workflow. docs/I18N-GLOSSARY.md updated for the v2.0 anchor set.

Fixed

• enableIdbAtRestEncryption default drift: featureCatalog declared defaultOn: false, contradicting the slice (true, the source of truth) — reconciled.
• README metric drift: scripts/sync-readme-metrics.mjs hard-coded the locale count to 11, so its regexes stopped matching after the 11→17 expansion and silently froze the i18n key count. Locale count is now dynamic and the regexes match any digit count — README reads the live 17 locales / 2786 keys with the drift guard green.

Changed

• Dependency hygiene + onboarding + docs truth-up: documented the joi accepted-risk override (GHSA-q7cg-457f-vx79; still required via wait-on) and the SBOM deferral in AUDIT.md (pnpm audit --audit-level=high clean); corrected the stale public/sw.js "must hand-sync APP_VERSION" note in CLAUDE.md; added a "Do NOT run heavy suites locally" callout + Minimal Change Checklist to CONTRIBUTING.md and mirrored the heavy-suite warning into .github/copilot-instructions.md.

• Docs completion (language-expansion pass): README i18n badge, language list, capability table and metrics line updated to 17 locales / 2716 keys; Persian added to the RTL-Beta section; AUDIT.md follow-up chain + quality-gate entry for 2026-06-17.

[1.23.1] — 2026-06-17

Fixed

• Tauri desktop app stuck on "WorldScript Studio ist offline.": the PWA Service Worker was registering inside the Tauri WebView (WebView2 supports SWs) and hijacking the root navigation. When its versioned caches were empty (precache fails under the tauri.localhost custom protocol while a version bump had already pruned the previous caches), the SW's network-first navigation strategy fell through to the hardcoded inline offline fallback (public/sw.js), rendering a bare " ist offline." page instead of the app. A Service Worker has no place in Tauri — the desktop app is already served locally and offline-first. Two-layer fix: (1) register-sw.ts now detects the Tauri runtime and never registers, additionally unregistering any SW + deleting worldscript-* caches so already-broken installs self-heal; (2) public/sw.js detects the Tauri origin (tauri:// / tauri.localhost) and becomes a no-op — it precaches nothing, never intercepts fetch, and self-unregisters on activate. The browser PWA path is unchanged.

[1.23.0] — 2026-06-16

Changed

• v1.23 P0 tracker reconciliation (docs): ROADMAP.md, TODO.md, and AUDIT.md brought into agreement after a drift where ROADMAP marked all v1.23 P0 items done while TODO still listed three as open. Each item is now evidence-backed (audit output, CI run, file existence). The manual smoke-test run is split out as a tracked human-only step (the protocol document itself is complete).
• AUDIT.md Known Overrides table refreshed: added the just-merged esbuild >=0.28.1 override (GHSA-67mh-4wv8-2f99, dev-server CORS), replaced placeholder advisory strings with verified GitHub Advisory IDs (re-checked 2026-06-13), and labelled preventive-only pins honestly. Dependency hygiene re-verified: pnpm audit high and moderate → 0 vulnerabilities.
• Dependency maintenance (Dependabot): bumped @ai-sdk/openai, @ai-sdk/google, yjs, tailwindcss, turbo, lint-staged, and the log crate to current patch/minor releases (web CI green on each).

Added

• Plugin sandbox adversarial test coverage: tests/unit/workers/plugin.worker.test.ts gains WebAssembly-denial, GeneratorFunction/AsyncGeneratorFunction constructor-escape, and guard-restoration (success + error path) tests for the v1.22 plugin-isolation hardening. New living audit artifact docs/AUDIT-PERFECTION-PLAN-v1.23.md tracks the 6-phase perfection engagement and its follow-ups.
• AI error taxonomy (services/ai/aiErrorTaxonomy.ts): pure classifyAiError(err) → { category, retryable, messageKey } across transient / rateLimit / auth / network / offline / policy / invalidRequest / canceled / permanent (cancellations via AbortError fail fast — never retried). Consumed by the retry layer.
• Actionable AI error messages in the Copilot: when an AI call fails, the Copilot now shows a localized, recovery-oriented message (e.g. "Invalid or missing API key — open Settings → AI & Models to add or update it.") instead of a generic "Something went wrong". Maps each taxonomy category to a new error.ai.* key (9 keys × 11 locales; translated in de/en/es/fr/it, English fallback in Beta/RTL) via a reusable getAiErrorMessage(err, t) helper.
• AI request correlation IDs: each AI generation now gets one opaque correlation id (newCorrelationId, services/logger.ts) shared by the request-start log (useWorldScriptAI), the fetch-side failure log (worldScriptCompletionFetch, propagated via the request body), and the retry seam (withTransientRetry) — for end-to-end traceability. No prompts or keys are logged.
• Rebrand to WorldScript Studio: rename StoryCraft Studio → WorldScript Studio across user-facing code, assets, PWA manifest, Tauri config, i18n (11 locales), docs, and CI/CD. New identifiers: worldscript-studio package, com.worldscript.studio Tauri identifier, /WorldScript-Studio/ GitHub Pages base, worldscript:// deep-link scheme, .worldscript/.wsst file associations. PWA service-worker cache names bumped to worldscript-* v1.23.0 to invalidate stale caches. Feature-Flags localStorage key, IndexedDB database names, and accessibility CSS class tokens all renamed to worldscript-*. This is a pre-release rebrand with no existing installs, so no storage migration is required (the storycraft-driver-popover onboarding-tour token is the one intentionally unchanged token, as its class usage was not renamed).
• Test coverage — Tauri filesystem backend (Phase 2): services/fs/ (the desktop FS storage chain — project/snapshot/asset/settings/codex stores + fsCore) went from 0% to ~81% line / ~66% branch coverage via an in-memory fake-TauriApis harness that drives real round-trips (LZ-String compression, AES-GCM API-key encryption, JSON, import/export). 37 new tests (tests/unit/services/fs/).
• Local-first data model foundation (behind enableLocalFirstSync, off by default): a perf baseline harness (pnpm bench, A0.1), a Y.Doc proof-of-concept (services/localFirst/projectDoc.ts, B0.1), and an incremental write-through doc binding + debounced shadow-sync (docBinding.ts / docPersistence.ts, B1.1) that keeps a Yjs shadow in lockstep with Redux without affecting users — Redux stays the source of truth during the shadow phase. ADR-0008. (#140)

Fixed

• Desktop app no longer launches to a blank window: the Tauri build resolved Vite's base from TAURI_PLATFORM — the Tauri 1.x env var, which Tauri 2.x never sets — so every desktop build fell through to the GitHub Pages base (/WorldScript-Studio/) and 404'd its hashed assets under tauri://localhost/, leaving only the native file/help menu over an empty webview (Windows/macOS). Base resolution now checks TAURI_ENV_PLATFORM (legacy name kept as a fallback) and is extracted into a unit-tested config/resolveViteBase.ts so the regression can't return. Note: the Linux .deb/AppImage require webkit2gtk-4.1 (Ubuntu 22.04+) — a Tauri 2 platform minimum, not a bug.
• AI retry no longer backs off doomed calls: withTransientRetry now classifies the error and fails fast on non-retryable categories (invalid API key, policy block, malformed request, offline) instead of retrying with exponential backoff. Transient / rate-limit / network errors still retry (honoring Retry-After). Each retry decision emits a structured ai.retry log line with a per-call correlation id (no payloads or keys). A shouldRetry option allows callers to override the default.
• Plugin worker no longer leaks a sandbox guard across runs (FU-1): workers/plugin.worker.ts restored Function.prototype.constructor through the bare Function identifier, which install had reassigned to the denied stub — so the real constructor stayed neutered after a plugin run. Restoration now routes through the module-captured native Function, keeping the dedicated worker's global scope clean between tasks. Restoration is also hardened: the self.* bindings are restored first and unconditionally, and each constructor is force-redefined via Object.defineProperty (best-effort), so a plugin that locks a property descriptor cannot abort the restore and poison subsequent runs. Isolation during execution is unchanged.
• Command Palette fully localized: ~20 command labels and category headers (AI Execution Modes, editor modes, appearance presets, accessibility toggles, Navigation/Editor/Global/etc.) were showing English in de/es/fr/it because the keys existed but the values were never translated. All are now translated for the core locales (de/en/es/fr/it). A new guard test (tests/unit/i18n/paletteLocalization.test.ts) fails if any palette.* key reverts to English fallback in a core locale (with a small allowlist for loanwords). Beta/RTL locales remain English-fallback by policy.
• Writer shows localized, classified AI errors: the Writer's generation-failure handler dispatched a hardcoded English string ("Error generating content…") and a hardcoded [Cancelled] tag. It now uses getAiErrorMessage(err, t) (same actionable, localized messages as the Copilot) and a localized writer.cancelledTag.
• OpenRouter cloud-policy block is now reactive: the OpenRouter settings panel derives its blocked state from live Redux (aiMode + privacy.localStorageOnly) instead of a one-shot async check, so toggling Local storage only or switching the AI mode updates the banner and the test-connection / catalog-fetch guards instantly. Split into distinct policyBlocked.mode / policyBlocked.localOnly messages (translated across the 8 non-stub locales) and fixed an infinite render-loop in the policy-blocked catalog path. (#163)
• Local AI settings localized: the 40 English-only settings.ai.localAi.* keys (WebGPU capability, model downloads, storage usage, fallback chain, throughput) translated for de/es/fr/it/el/ja/pt/zh (ar/he stay English stubs; model names unchanged). (#164)
• Real WorldScript app icons: replaced the placeholder icons — generic 16-bit RGBA PNGs that broke the macOS/Windows Tauri bundler (unsupported ColorType: Rgba16) and blocked the desktop release — with a new "W" quill-nib monogram, regenerated as 8-bit across favicon.svg, the PWA icons, and the full Tauri icon set (incl. a newly generated icon.icns). Also fixed remaining StoryCraft URLs in robots.txt / sitemap.xml / _redirects / CNAME.example and renamed the Cloudflare Pages project in wrangler.toml. (#165)

[1.22.0] — 2026-06-11

Added

• OpenRouter provider (Cloud 5): Unified gateway to 100+ open-source models. services/ai/providers/openrouterProvider.ts — circuit breaker (4 × 429 → 5 min pause), RPM tracking, free-tier catalog (deepseek/deepseek-r1:free, meta-llama/llama-3.3-70b-instruct:free, qwen/qwen2.5-72b-instruct:free, google/gemma-3-27b-it:free, mistralai/mistral-7b-instruct:free). Settings → OpenRouter panel with enable toggle, API key (AES-encrypted), model selector. Sign up at openrouter.ai/keys — no credit card for :free models.

• AI Execution Modes: AiMode = 'hybrid' | 'cloud' | 'local' | 'eco' — four routing strategies exposed in Settings → AI & Models → AI Execution Mode:

  • Hybrid (default): local models when preloaded → cloud fallback
  • Cloud: all requests to configured cloud provider
  • Local: on-device only via Ollama / WebLLM / ONNX — nothing leaves the device
  • Eco: battery-saving tiny 0.5B model + heuristics only; no cloud, no GPU aiModeService.ts persists the active mode to settings.aiMode; listenerMiddleware syncs without page reload. AiModeIndicator chip in the Copilot header shows the active mode and turns amber when the OpenRouter circuit breaker is open.

• Ultimate Copilot AI v2 — Phase 2+3 (PR #110, #111):

  • Markdown rendering in CopilotMessageList — assistant messages rendered as sanitised HTML (DOMPurify + inline micro-markdown renderer; headings, bold, italic, code blocks, lists). No new runtime dependency.
  • Sidebar/dialog mode toggle — panel can be docked to the right edge on desktop (≥ 768 px); preference persisted in localStorage. Mobile always uses dialog mode.
  • Apply-to-chapter — "Apply to chapter" button on the last assistant code block rewrites the active manuscript chapter via applyTextEdit (offset-safe, dispatched into redux-undo for Ctrl+Z reversal). Gated to blocks ≥ 70 % of section length to prevent partial-snippet overwrites.
  • InlineAnnotationLayer — absolute-positioned badge inside ManuscriptEditor showing the heuristic-insight count for the active chapter. Clicking opens the Copilot and auto-expands the Insights section.
  • ProForge "Ask Copilot" chip — each ReviewItemCard in the ProForge Review Panel shows an ✦ Ask Copilot button (gated by enableGlobalCopilot) that pre-fills the Copilot composer with the item's context.
  • docs/COPILOT.md — user-facing feature guide (architecture, modes, Apply-to-chapter, ProForge integration).
  • docs/HEURISTIC-RULES.md — per-rule reference (8 rules, how-to-satisfy, i18n key pointers).
  • 2 new E2E tests — heuristics-only toggle and sidebar mode toggle in copilot-flags.spec.ts.

• WebLLM worker offload (P1-1, ADR-0005): @mlc-ai/web-llm (WebGPU) inference now runs in a dedicated WorkerBus v2 webllm pool (workers/v2/webllm.worker.ts, capability inference.webllm) instead of inline on the main thread. Worker-first with an automatic main-thread fallback on NO_WEBGPU / worker-spawn failure / circuit-open, decoupled from enableWorkerBusV2. GPU mutex + tab-leader election stay on the main thread; loading progress bridges to inferenceProgressEmitter so the UX is unchanged.

• Whisper WASM STT end-to-end tests (P1-2): A deterministic, deep-E2E suite (tests/e2e/deep/voice/whisper-stt.spec.ts) exercises the full voice orchestration — simulated model download (progress / cancel / error → retry), STT → intent → command-dispatch navigation, and stop-listening stability — via a guarded test seam (services/voice/voiceTestSeam.ts). A non-blocking nightly workflow (voice-nightly.yml) runs the real Whisper download + pipeline init against the live CDN.

Changed

• Voice hardening (v1.21 follow-up): Transcript redacted from the intent-engine debug log (C-P0 — user speech is PII and the IDB log sink persists it); single-flight guard on VoiceCommandService.startListening against re-entrant push-to-talk / wake-word starts; download modal progress is now an accessible role="progressbar" with a polite live region (Progress atom + VoiceModelDownloadModal).
• i18n: 2 594 keys × 11 locales (+62 keys for AI Execution Modes, OpenRouter settings, Copilot v2 actions).

Fixed

• Prompt injection & plugin isolation hardening (PR #114):
  • services/proForge/applyReviewEdits.ts now rejects C0 control characters (except \t, \n, \r), null bytes, and lone surrogates in AI-proposed edits; invalid items are skipped individually instead of aborting the whole batch.
  • services/copilot/actionApplier.ts whole-section replacement on empty chapters now works by passing an explicit full-range edit.
  • services/pluginRegistry.ts enforces stricter storage-key validation: maximum length, allowed suffix characters, anti-traversal (..), and a 2 MiB serialized value size cap.
  • components/copilot/CopilotMessageList.tsx DOMPurify config hardened with ALLOW_DATA_ATTR: false, FORBID_ATTR: ['style'], and SANITIZE_DOM: true.
• PWA blank screen on update: SW APP_VERSION bumped 1.20.0 → 1.21.2 so the activate handler correctly prunes the stale storycraft-static-v1.20.0 cache after deployment.

---

[1.21.0] — 2026-06-10

Added

• Sepia dark mode — "Candlelit Manuscript" variant: New warm low-light theme variant joining the light/dark/sepia families; body-class themed via --sc-* tokens (no dark: prefix). (1321478)
• Deep E2E coverage layer: Non-blocking e2e-deep job — feature-flag matrix (tests/e2e/deep/feature-flag-matrix.spec.ts) parametrized across test-matrix.ts, plus error-path specs (offline AI, rapid nav, all-flags-on). Explicit per-flag specs seed state via setFeatureFlags(). (663ca2f)
• Chinese (zh) locale + pt/el Beta translation batches: zh Simplified brought under the 5% English-placeholder target; pt/el Beta translation batches landed. (364025e, e8cddcb)
• Whisper WASM STT download UI + VAD→Whisper bridge: VoiceModelDownloadModal ships; VoiceActivityCoordinator wires WebRtcVadEngine PCM frames into WasmSttEngine (MIN_SPEECH_CHUNKS gate + MAX_BUFFER_MS flush) behind enableVoiceWasm. (e8cddcb, 364025e)

Changed

• CSP connect-src — documented BYOK tradeoff (ADR-0004): Explicit cloud-provider endpoints in index.html connect-src removed as redundant; the intentional https: scheme-source (required by the shipped openAiCompatibleBaseUrl BYOK feature) is retained and documented. Tauri CSP stays strict (no https: blanket). Regression test in tests/unit/csp.test.ts.
• Coverage batches A–C: Incremental unit-test coverage additions; thresholds held at lines 74 / functions 67 / branches 60 / statements 72. (364025e)
• Dependency bumps: @huggingface/transformers 3.8.1 → 4.2.0 — major bump verified (WS-3): the APIs ai-core/voice consume are unchanged in v4.2.0 (pipeline(task, model, { dtype, device }), env.backends.onnx.wasm.proxy, RawAudio/read_audio exports); pnpm typecheck clean and 63 ai-core/voice integration tests green; no source changes required. Production bundling (rolldown tree-shaking / vendor-ai-onnx chunk) is exercised by the CI build + smoke:prod jobs. Also @biomejs/biome → 2.4.16, @mlc-ai/web-llm → 0.2.84, vite → 8.0.16, @google/genai → 2.8.0, @tanstack/react-virtual → 3.14.2.

Fixed

• Command palette footer contrast (a11y): text-muted → text-secondary for WCAG 2.2 AA contrast. (672e56d)
• Voice settings tab + auto-save false-positive + help locale cleanup. (e049f08)
• E2E / CI stabilization: viewport-aware nav locators, ProForge empty-state visibility on Desktop Chrome, Voice WASM section, Early-Access hyphenated German label, and 17 unit-test fixes across SettingsView/HelpView/VoiceSettingsSection. (43602c2, f16ba42, 3cf9387, fe598ed, d73397e)

Docs

• Integrity & hardening cycle (v1.21, audit F-1…F-9): README badge → released v1.20.0 + refreshed metrics (433 test files / 2 357 i18n keys); 28 misfiled v1.19-era CHANGELOG entries migrated to [1.19.0]; TODO sprint rollover. ADR-0004 (CSP/BYOK). New suppression-count ratchet gate (scripts/check-suppressions.mjs, wired into CI quality) + first abatement tranche — 22 noExplicitAny suppressions removed, baseline ratcheted 181 → 159. Bundle-budget single source of truth (bundle:budget = --max-kb 6500 --max-entry-kb 4000, script defaults aligned). Governance docs: VENDOR-FORKS.md gains a CVE/OSV-coverage section (the vendored y-webrtc source is invisible to OSV — manual upstream-advisory process documented), new docs/COVERAGE-POLICY.md (threshold ratchet rule).

---

1.20.0 — 2026-06-07

Added

• UI Modernization Phase 1 — LanguageSelector, RadioGroup, Tabs:
  • LanguageSelector.tsx — Modern combobox with search functionality, flag emojis, RTL support, and reduced-motion awareness. Replaces inline language buttons in WelcomePortal with a searchable dropdown.
  • RadioGroup.tsx — Accessible radio group component with proper ARIA attributes (role="radiogroup"), individual option descriptions, and glassmorphism styling.
  • Tabs.tsx — WAI-ARIA compliant tabs component with three variants: default, pills, and underline. Includes TabPanel component for content association.
  • SettingsShared.tsx — ToggleSwitch optimized for RTL layouts with reduced-motion support.
  • docs/UI-MODERNIZATION.md — Comprehensive guide for UI component usage, migration patterns, and design principles.
• Phase 3 i18n Expansion — ja/zh/pt/el Beta languages + Intl APIs:
  • Added Japanese (ja), Chinese Simplified (zh), Portuguese (pt), and Greek (el) as Beta languages with English placeholder text
  • Extended Language type and VALID_LANGS array in I18nContext.tsx
  • Added SUPPORTED_LOCALES metadata array with BCP47 codes, native names, direction, and font script hints
  • Integrated native Intl APIs with caching: Intl.PluralRules, Intl.NumberFormat, Intl.RelativeTimeFormat, Intl.Collator, Intl.ListFormat, Intl.DisplayNames
  • Added getPluralCategory(), formatNumber(), formatRelativeTime(), getCollator(), formatList(), formatDisplayName() to I18nContextType
  • Auto-formatting of {{count}} placeholders in t() function
  • Fonts: Noto Sans JP via Google Fonts CDN for Japanese/Chinese; Greek uses system fallback
  • CSP updated to allow fonts.googleapis.com and fonts.gstatic.com
  • Documentation: docs/I18N-PLURALS.md, docs/I18N-NUMBERS.md, docs/I18N-LOCALE.md, docs/I18N-RELATIVETIME.md, docs/I18N-COLLATION.md, docs/I18N-LISTFORMAT.md, docs/I18N-DISPLAYNAMES.md, docs/I18N-GLOSSARY.md
  • 2339 keys × 11 locales (up from 2259 × 7)
  • 53 unit tests covering all Intl APIs

Fixed

• World Building "Add Manually" now opens the atlas editor (2026-06-03): useWorldView.handleAddNewManually only dispatched addWorld and left the user on the grid with a silent "New World" card and no editor — inconsistent with Characters, whose manual-add was deliberately fixed to open the dossier. Now mirrors that flow (create → select → open atlas) with fully-formed defaults (timeline/locations as []). Adds real-browser tests/e2e/world.spec.ts (was none) + a hook-level regression assertion.
• CI unblock — OSV paste advisory + Vercel rate-limit noise (2026-06-03):
  • src-tauri/osv-scanner.toml — ignore RUSTSEC-2024-0436 (paste 1.0.15 unmaintained; build-time proc-macro helper, no runtime exposure, no fix release). The advisory was newly published and was failing the required Security Audit check on every branch (e.g. Dependabot PR #78).
  • vercel.json — "github": { "silent": true } so Vercel still deploys but no longer posts commit statuses; the free-tier "Deployment rate limited — retry in 24 hours" preview failure can no longer show as a hard fail on PRs. (Vercel was never a required status check, so this is purely cosmetic-noise removal.)

Added

• Tauri Desktop Pipeline — P0-1 complete (2026-06-06):

  • pnpm-workspace.yaml migration — moved overrides, peerDependencyRules, onlyBuiltDependencies, patchedDependencies, ignoredBuiltDependencies, and allowBuilds from deprecated package.json "pnpm" field to pnpm-workspace.yaml; resolves ERR_PNPM_LOCKFILE_CONFIG_MISMATCH on CI
  • tauri-build.yml — shell: bash for Windows compatibility; skips TAURI_SIGNING_PRIVATE_KEY for workflow_dispatch test builds; jq-disables createUpdaterArtifacts when no signing key is available (prevents "public key found, but no private key" error)
  • macOS: removed invalid exceptionDomain object and signingIdentity: "-" from bundle config; added Entitlements.plist with hardened-runtime permissions
  • Release profile hardening: lto = true, codegen-units = 1, strip = true, panic = "abort"
  • Bundle metadata: category, publisher, copyright, shortDescription, longDescription
  • Verified: ubuntu-22.04 (deb, rpm, AppImage), windows-latest (MSI), macos-latest (DMG) all build successfully

• Coverage C-7 — 96 new unit tests (2026-06-06):

  • tests/unit/loraDatasetBuilder.test.ts (19) — scene pair extraction, quality scoring, synthetic generation, JSONL export (Alpaca/ChatML/ShareGPT), quality report estimation
  • tests/unit/loraEvaluationService.test.ts (16) — cosine similarity, mean similarity, style consistency scoring, score labels, prompt output comparison
  • tests/unit/intentEngine.test.ts (17) — exact template matching, fuzzy Jaccard scoring, navigation slot extraction, view context filtering, command replacement
  • tests/unit/feedbackService.test.ts (23) — TTS queue processing, feedback level filtering (minimal/standard/verbose), mute behavior, event emission, confirm/error/info helpers
  • tests/unit/audioNavigator.test.ts (21) — ARIA landmark scanning (main/nav/aside/region/search), focus cycling, tabindex management, live region announcements with priority switching

Security

• Accidentally committed signing keys removed (2026-06-06): ~/.storycraft-tauri.key and ~/.storycraft-tauri.key.pub were committed in da7653b; rotated in GitHub Secrets, files removed, .gitignore hardened with *.key, *.pem, *.p12, *.pfx, *.cer, *.der, *.sig.key
• aiohttp CVE remediation (2026-06-06): bumped aiohttp==3.11.16 → 3.14.0 in scripts/ci-analyzer/requirements.txt; resolves 21 Dependabot CVEs (GHSA-...)

1.19.0 — 2026-05-28

Added

• B-1 — IDB At-Rest Encryption (services/storage/storageEncryptionService.ts): Full AES-256-GCM passphrase-derived encryption for IndexedDB stores. PBKDF2 (600 000 iterations, SHA-256, 32-byte random salt stored in app-data as idb_kdf_salt_v1). CryptoKey is { extractable: false }. Feature-flagged behind enableIdbAtRestEncryption (off by default). Tauri build uses tauri-plugin-stronghold for OS-keychain-backed passphrase (zero user friction). Web build shows passphrase unlock modal on cold start (session-scoped in-memory key wiped on tab close). GDPR threat model: encrypted blobs unreadable without passphrase from browser profile or malicious extension. Storage decomposition in services/storage/ (idbCore, idbProjectStore, idbSnapshotStore, idbKeyStore, idbCodexStore, idbAssetStore).

• B-2 — Voice WASM Engine Scaffold (services/voice/wasmSttEngine.ts, services/voice/sileroVadEngine.ts): Whisper.cpp WASM STT engine interface scaffold (model download, chunked inference, 99+ language detection). Silero VAD v4 via ONNX Runtime Web (~2 MB model, lazy-loaded). Both implement the existing abstract SttEngine / VadEngine interfaces from voiceTypes.ts. Feature-flagged behind enableVoiceWasm (off by default); falls back to WebSpeechSttEngine / WebRtcVadEngine when off.

• B-3 — collab-transport Vendor Fork (packages/collab-transport): Vendor fork of y-webrtc 10.3.0 with RTCDataChannel in-flight E2E encryption baked into the package source. Replaces the pnpm-patch approach (patches/y-webrtc@10.3.0.patch). All Yjs sync updates and awareness protocol messages over peer-to-peer WebRTC data channels are encrypted via AES-256-GCM using room.key. Workspace package consumed as workspace:*.

• B-4 — axe-core E2E Accessibility Gate (tests/e2e/a11y-axe.spec.ts): 8-view axe-core WCAG 2.2 AA Playwright scan run in CI on every push. Views covered: Dashboard, Writer, SceneBoard, Characters, Worlds, BookPreview, ProgressTracker, Settings. Zero violations enforced (expect(violations).toHaveLength(0)); known non-blocking notices logged but not failed.

• B-5 — RTL Layout Beta: Arabic (ar) and Hebrew (he) locale stub files added to locales/. enableRtlLayout feature flag activates html[dir="rtl"] and a BiDi context provider for bidirectional text layout. Full RTL translation content and Persian (fa) support are v2.0 milestones. Existing enableRtlLayout flag wired to html[dir] control in App.tsx.

• B-6 — StructuredLogger (services/logger.ts rewrite): Ring-buffer replaced with a multi-sink structured logger:

  • IDB sink — storycraft-logs-db / logs store, 1 000-entry LRU cap, auto-eviction via forward cursor.
  • Tauri JSONL sink — $APPDATA/logs/storycraft-YYYY-MM-DD.jsonl, lazy-loaded Tauri FS modules, date-rotated, { append: true, create: true }.
  • Console sink — DEV-only, prefixed [StoryCraft:LEVEL:module].
  • GDPR sanitization — sanitizeLogContext(ctx) redacts values whose key matches /key|token|password|passphrase/i.
  • New API — createLogger(module): ModuleLogger factory with .debug()/.info()/.warn()/.error() and .withContext(ctx) for structured context injection. Default logger export and getRecentLogs() / formatLogsForReport() / clearLogs() retained for backward compatibility.

• B-7 — Coverage Thresholds Raised: Vitest gate: Lines ≥ 71 / Functions ≥ 63 / Branches ≥ 57 / Statements ≥ 69. Measured: 73.06% L / 65.18% F / 58.79% B / 71.29% S — all green.

• B-8 — Stryker Gate Raised: thresholds.break raised 70 → 75. mutate targets expanded from 34 → 40 source files to cover new services introduced in B-1..B-6.

• Sequential shell execution rule codified in all 4 instruction files (CLAUDE.md project root, .github/copilot-instructions.md, .cursorrules, infra/low-end-ci/DAILY-DRIVER.md) — ONE Bash call per response, no parallel shell calls on this 3.7 GB RAM hardware.

• WebGPU detector service (2026-05-18): New services/ai/webGpuDetectorService.ts — detectWebGpuDetails() queries navigator.gpu.requestAdapter(), reads adapter.limits.maxBufferSize for VRAM tier heuristic (≥8 GB = high, ≥4 GB = medium, else low). AiProviderCard gains live GPU status badge, WebLLM model dropdown, and ONNX model dropdown. LOCAL_INFERENCE_PROVIDERS + isLocalInferenceProvider() added to orchestrationProviders.ts. 12 new settings i18n keys across all 5 locales (1408 → 1414 total).

• ONNX Runtime Web Layer-2 in ai-core (2026-05-18): packages/ai-core/src/index.ts adds an ONNX WASM fallback layer between WebLLM and Transformers.js. LocalAiLayer type includes 'onnx'. ONNX_SUPPORTED_MODELS exported. vite.config.ts gains vendor-ai-onnx manual chunk to keep onnxruntime-web + @xenova/transformers under Workbox's 8 MiB SW cache limit.

• Yjs AES-256-GCM encryption foundation (2026-05-18): collaborationService.ts gains encryptUpdate(), decryptUpdate(), deriveEncryptionKey() (PBKDF2 600 000 iterations, SHA-256, AES-256-GCM), and getEncryptionStatus() ('encrypted' | 'psk-only' | 'plaintext'). CollaborationPanel.tsx shows green/amber encryption status badge post-connect. 3 new collab i18n keys.

• Tauri v2 auto-updater pipeline (2026-05-18): tauri-build.yml gains a Generate latest.json step that builds the Tauri v2 update manifest from signed .sig files and uploads it to GitHub Release. docs/TAURI-UPDATER.md extended with a full GitHub Secrets table. docs/TAURI-CI.md gains a 7-step first-release checklist.

• Cross-Project-Search v2 (2026-05-18): DB_VERSION 7→8 with new projects-index-store. New crossProjectIndexService.ts — indexProject(), listIndexedProjects(), removeProjectIndex() (privacy-preserving: no manuscript plaintext). searchAcrossProjectIndex() added to crossProjectSearchService.ts. CrossProjectSearchPanel.tsx runs two-phase search (index first, then current project). 3 new crossSearch.* i18n keys (1414 total).

• Mobile-aware E2E helpers (2026-05-17): clickNavItem(page, name) in tests/e2e/helpers.ts — tries desktop #sidebar (hidden md:flex), then mobile bottom-tab-bar ([data-tour="nav-mobile"]), then the "More" sheet; eliminates all sidebar(page) calls that fail on Pixel 5 viewport. selectFirstEnabledWriterSection now switches to the context tab on mobile before locating the section selector.

• ARIA tablist on WriterView mobile segmented control: Each tab button gains role="tab", aria-selected, aria-controls, data-testid="writer-tab-{context|tools|result}"; container gains role="tablist"; panel divs gain role="tabpanel" + aria-labelledby — axe-compliant and stably selectable in Playwright.

• Mobile VC button in WriterViewUI: md:hidden version of the version-control toggle button with data-testid="writer-version-control-btn" and aria-expanded — mirrors the desktop button that is hidden on Pixel 5 viewport.

• Stable test anchors: data-testid="snapshot-label-input" on the snapshot-label <Input> in VersionControlPanel.tsx; data-testid="export-preview" on the <pre> export preview in ExportView.tsx.

• OSV vulnerability scan in CI security job: google/osv-scanner-action@v2 step wired after pnpm audit — osv-scanner.toml existed but was never executed; advisories now caught on every push/PR.

• JUnit E2E artifact: Playwright JUnit reporter output (tests/e2e/results/junit.xml) uploaded as e2e-junit artifact — enables per-test check annotations on GitHub PRs.

Changed

• services/logger.ts — backward-compat logger export, getRecentLogs(), formatLogsForReport(), and clearLogs() retained; in-memory cache kept at 200 entries as fast path for formatLogsForReport.

• packages/collab-transport replaces pnpm-patched y-webrtc dependency; patchedDependencies entry removed from package.json.

• i18n Comprehensive Sweep (2026-05-18): All remaining hardcoded user-facing strings eliminated across 5 locales — 1 440 keys total (up from 1 414). Fixes include: help.tryTour (was rendering raw key "try.Help" in the command palette), initialProject.chapter1 ("Chapter 1" in projectSlice + AdvancedImportExport — extended resetProject payload with optional chapter1Title), manuscript.resizer.left/right (hardcoded German string "Linkes Panel anpassen" remained in source), writer.stopGenerating / tools.selectLabel / versionControl.tooltip, settings.ai.temperature.precise/balanced/creative, export.pasteSection.heading ("Google Docs / Notion"), outline.result.body, characters.uploadImage / editorTabsAriaLabel, worlds.uploadImage / editorTabsAriaLabel, templates.tabs.myTemplates / community, error.boundary.title/description/reset/reload/report, manuscript.spellcheck.didYouMean/applyFix, manuscript.grammar.checkButton, manuscript.zenMode.enter/exit/label, and writer.studio.controls.custom/customTonePlaceholder.

• ErrorBoundary fully localized (2026-05-18): components/ui/ErrorBoundary.tsx refactored with inner ErrorFallback functional component — accesses useTranslation() hook to render title, description, and all buttons (Reset View, Reload Page, Report issue) in the active locale. Import path corrected to hooks/useTranslation; onReset passed conditionally to satisfy exactOptionalPropertyTypes.

• Unit-test coverage — 1 641 tests / 150 test files (2026-05-18): Measured 62.86 % statements · 49.06 % branches · 54.10 % functions · 64.68 % lines. Vitest thresholds at statements 53 / branches 37 / functions 50 / lines 55 — all passing.

• Unit-test coverage — Phase 4.5 thresholds met (2026-05-17): Measured 63.32 % lines · 61.5 % statements · 47.1 % branches · 53.2 % functions (1 561 tests). Vitest thresholds at lines 55 / statements 53 / branches 37 / functions 50.

• Stryker mutation gate enforced: thresholds.break raised null → 30; timeoutMS lowered 180 000 → 120 000 ms; CI mutation job continue-on-error → false, timeout-minutes: 20 → 30.

• Lighthouse performance promoted to error: categories:performance warn:0.5 → error:0.4; categories:seo added as warn:0.8; FCP tightened 6 000 → 5 000 ms; LCP tightened 8 000 → 7 000 ms.

• CI concurrency fix: cancel-in-progress restricted to PRs only — main-branch deploys no longer cancelled by a concurrent push.

• Artifact retention aligned: dist 7 → 3 days; lighthouse-report and storybook 14 → 7 days.

• Unit-test coverage — Phase 1 thresholds met: 17 new test files added (733 tests total); Vitest coverage thresholds bumped to { lines: 35, functions: 30, branches: 22, statements: 33 } (previously 25/21/17/24). Measured coverage: 36.47 % lines · 35.53 % statements · 24.96 % branches · 30.22 % functions — all Phase 1 targets exceeded. New files cover: commands/ (fuzzyScore, palettePreferences, commandSystem), project thunks (writing, character, binder, management), hooks (useDashboard, useManuscriptView, useGlobalKeyboardShortcuts, useCharacterView, useOutlineGenerator), aiProviderService fallback chain, dbService snapshots, dbService binder assets, and crossProjectSearchService.

• Stryker mutation targets expanded (Phase 4): stryker.conf.json mutate array now includes services/commands/fuzzyScore.ts, services/commands/palettePreferences.ts, and services/commands/commandBuilder.ts in addition to the existing codexService.ts and dbMigration.ts.

Fixed

• TypeScript 6 strict hardening (2026-05-18): 'grok-3' and 'grok-3-mini' added to AiModel union in types.ts (TS2322 in aiProviderService.test.ts); double-cast (x as unknown as Record<string, unknown>)['key'] pattern for CollaborationService private member access (TS2352); bracket notation ['gpu'] / ['__TAURI__'] required by TypeScript 6 index-signature enforcement (TS4111); PBKDF2 Uint8Array<ArrayBuffer> generic in collaborationService.ts for Web Crypto API strict typing.

• Test mocks (2026-05-18): tests/unit/ErrorBoundary.test.tsx gains vi.mock('../../hooks/useTranslation', …) with an EN string map so rendered-text assertions survive the i18n refactor. tests/unit/AdvancedImportExport.test.tsx heading assertion updated from hardcoded 'Google Docs / Notion' to 'export.pasteSection.heading' (consistent with the t: (k) => k mock pattern already used in that file).

• E2E Desktop + Mobile Chrome (2026-05-17): writer, snapshots, a11y, export spec files migrated to 2026 Golden Hierarchy selectors (getByRole > getByTestId; no CSS, no XPath). Fixes CI exit-code 1 after WriterView component split.

• WebLLM model selector (Phase 3B): packages/ai-core now exports WEBLLM_SUPPORTED_MODELS (4 curated MLC-packaged checkpoints: Llama 3.2 1B, Llama 3.2 3B, Phi-3.5 Mini, Gemma 2 2B), WebLlmModelId, and WebLlmProgressReport types. runLocalTextGeneration accepts an optional modelId and onProgress callback for per-model download-progress tracking. services/localAiFacade.ts forwards both parameters. types.ts expands the AiModel union with the four specific MLC model IDs. Settings → AI (Advanced) now shows a dynamic model dropdown populated from WEBLLM_SUPPORTED_MODELS, a pre-download button, a WCAG 2.2 role="progressbar" progress bar, and a useRef mounted guard that prevents setState-on-unmount. All 5 locale settings.json files gain the 3 new i18n keys (settings.ai.webllm.model, settings.ai.webllm.downloadProgress, settings.ai.webllm.downloading).

• Cross-project search service (Phase 3A): New services/crossProjectSearchService.ts — searchAcrossProjects(query, projectData) fuzzy-searches project title, logline, manuscript sections, and character names/fields using normalizeSearch() from fuzzyScore.ts; returns CrossProjectSearchResult[] sorted by score. Results include projectId, projectTitle, matchType, excerpt (truncated to 120 chars with …), and score. v1 scope is single-project (multi-project search requires a DB_VERSION bump + IDB migration — deferred to v2). app/transientUiStore.ts gains isCrossProjectSearchOpen + setCrossProjectSearchOpen. The labs-cross-project-search command in services/commands/commandDefinitions.tsx now opens the search panel instead of a stub toast. All 5 locale common.json files gain 7 crossSearch.* keys.

• Collaboration security warning (Phase 3C): CollaborationPanel.tsx displays a pre-connection security-warning banner (role="alert", aria-live="polite", WCAG 2.2 AA) that is only visible before connecting. The banner explains that the public y-webrtc signaling relay can observe connection metadata, includes a keyboard-accessible self-hosting link, and disappears once connected. All 5 locale common.json files gain collab.securityWarning, collab.securityWarningDetail, and collab.selfHostLinkLabel.

• E2E tests for new features: tests/e2e/commands.spec.ts — palette open/close (Ctrl+K / Escape), "dashboard" text search surfaces nav command, Enter-to-navigate, fuzzy "wrt" match. tests/e2e/collaboration.spec.ts — security warning [role=alert] is visible pre-connection and non-empty. Both specs are CI-only (test.skip(!isCI)).

1.18.1 — 2026-05-27

Fixed

• TypeScript strict-mode compliance sweep — Zero tsc --noEmit errors across all 47 changed files:
  • ProForge pipeline agents: AIRequestOptions requires model + provider; added buildAiOpts() protected helper to BaseAgent that derives provider/model from PipelineConfig.aiProvider with sensible defaults. Applied to all 7 pipeline agents + selfReflect() in BaseAgent.
  • productionAgent.ts: EpubExportOptions.author (required field) — added author: project.author ?? 'Unknown'.
  • services/proForge/pipelineTools/toolRegistry.ts: Wrong module paths ('../../app/store') → '../../../app/store'; same for features/proForge/types.
  • features/proForge/proForgeSlice.ts: exactOptionalPropertyTypes — optional properties assigned via conditional spread instead of explicit undefined.
  • features/proForge/types.ts: Array index access (PIPELINE_STAGES[idx]) returns T | undefined with noUncheckedIndexedAccess — coalesced to ?? null.
  • features/versionControl/versionControlSlice.ts: Added stub restoreSnapshot reducer (cross-slice signal, no self-state mutation).
  • hooks/useProForgeOrchestrator.ts: aiCreativity is on root Settings, not AdvancedAiSettings.
  • Voice components (VoicePrivacyConsentModal, VoicePrivacyStatus): Wrong useTranslation import path; Modal named export; setVoiceSettings action (not updateSettings); selectVoiceSettings selector.
  • Test fixtures (35+ test files): Corrected for noUncheckedIndexedAccess ([i]!), removed non-existent StorySection.type/order fields, act: 1 as const for literal union, AiModel/Theme/MindMapNodeType/StoryObjectType valid enum values, PrivacySettings with all 6 required fields, DeviceHealthReport correct shape, FlatHelpArticle.contentKey (not bodyKey), FeatureFlagsState.enableProForge in mock objects.

1.18.0 — 2026-05-27

Added

• ProForge Humanization & Refinement Sprint (Phases H/A/P/X) — Full editorial-quality overhaul of the ProForge pipeline:
  • Phase H — UX Polish: Author-facing stage labels and loading messages (no implementation jargon); RAG chunk count renamed to "context passages"; feature flag descriptions rewritten for non-technical readers; behavioral tests replacing implementation-detail tests.
  • Phase A — Architecture: BaseAgent abstract class eliminates ~200 LOC of duplicated scaffold across all 8 pipeline agents; services/ai/aiConstants.ts consolidates CREATIVITY_TO_TEMPERATURE, LOCAL_BACKEND_PRESET_DEFAULT_URL, and ORCHESTRATION_READY_PROVIDERS into a single source; addDebouncedListener factory in listenerMiddleware.ts replaces repeated RootState cast dance.
  • Phase P — Quality Supervision: SupervisorAgent — heuristic quality gates (no AI calls) that detect fallback sentinels and trigger retries via executeStageWithSupervision; hard gate blocks pipeline if intake qualityScore < 30; BaseAgent.selfReflect() — self-evaluation loop flags INCOHERENT output in DiagnosticAgent and StructuralAgent for re-run; all createFallback* methods now produce 0 scores + isFallback: true instead of fake data; reflectionNotes, supervisorDecision, and maxRetries fields added to relevant types.
  • Phase P-5 — PipelineReviewPanel Redesign: Critical Actions summary card; severity-grouped view (Critical / Warnings / Suggestions); Quick Accept High-Confidence button (confidence ≥ 0.85, non-critical, pending items only).
  • Phase X-1 — Settings Nav Grouping: Semantic NAV_GROUPS with NavGroupHeader component (Writing, AI Models, Appearance & Accessibility, Privacy & Data, Connections, System).
  • Phase X-2 — Flow Mode: Distraction-free writing mode via Zustand transientUiStore (flowMode / setFlowMode); WriterViewUI shows full-screen editor on toggle; Escape key exits.
  • Phase X-3 — Empty States: <EmptyState> components for Characters, World, SceneBoard, and ProForge views — contextual guidance when collections are empty.
• i18n: 2055 keys × 5 locales (added proforge.pipeline.title, proforge.pipeline.noneActive, loading messages, stage labels, empty-state strings across DE/EN/ES/FR/IT).
• .gitignore: Added .continue/ (Continue IDE local config directory).

Fixed

• listenerMiddleware.ts: getOriginalState() captured synchronously before the first await inside addDebouncedListener factory (RTK constraint — calling after any await throws at runtime).
• WriterViewUI.test.tsx: Added vi.mock for useWriterViewContext (component now requires the context after X-2 Flow Mode integration).
• ProForgeDashboard.test.tsx: Assertion updated to use i18n key string (mock t() returns key; component uses t('proforge.pipeline.noneActive')).
• writingAndCharacterThunks / outlineAndWorldThunks / plotBoardAiThunks tests (pre-existing): Added vi.mock('../../../services/ai/aiPolicy', ...) — settingsReducer defaults localStorageOnly: true, causing assertCloudAiAllowedSync to throw "Cloud provider blocked" and reject all 31 AI thunk tests at the gate.

1.17.1 — 2026-05-26

Fixed

• TypeScript errors in ProForge test suite — Fixed 30+ type errors across 15 ProForge test files: EntityState mock completeness (ids: []), full ProForgeState shape (isActive, activeView, defaultConfig, isLoading, error), PipelineStage / ReviewItemType / ReviewItemSeverity union casts in test helpers, activeStageResult.stage as PipelineStage, creativity as const / ragMode as const for union literal narrowing, generic t<T>(k) => k as unknown as T translation mock, versionControlActions.restoreSnapshot biome-ignore cast.
• Test failures in Coverage Sprint test files — NotificationsSection.test.tsx: getAllByRole('checkbox') → getAllByRole('switch') (ToggleSwitch uses ARIA role="switch"); Progress.test.tsx: querySelector('div > div') returned outer div (no inline style) → querySelector('[style]') targets the inner bar div; ManuscriptEditor.test.tsx: word count badge renders "7 common.words" not "7" — fixed to regex \b7\b; AnalyticsBootstrap.test.tsx: missing beforeEach(vi.clearAllMocks) caused stale call count; ragPromptAssembly.test.ts: token budget 50 too small for 500-char body (≈173 tokens) — corrected to 200.

Changed

• Dependencies (patch) — @ai-sdk/google 3.0.75→3.0.79, @ai-sdk/openai 3.0.64→3.0.65, @ai-sdk/react 3.0.187→3.0.193, ai 6.0.185→6.0.191, dompurify 3.4.5→3.4.6, @tanstack/react-virtual 3.13.25→3.13.26, vite 8.0.13→8.0.14, vitest + @vitest/coverage-v8 4.1.6→4.1.7, storybook suite 10.4.0→10.4.1, @types/node 25.9.0→25.9.1, @types/react 19.2.14→19.2.15.

1.17.0 — 2026-05-24

Added

• Voice Full Support Foundation — Abstract Engine Interfaces (SttEngine, TtsEngine, VadEngine, WakeWordEngine, IntentEngine), Web Speech API Fallbacks, Hybrid Intent Engine (exact → Jaccard → slot extraction), VoiceCommandService with State Machine (idle → listening → processing → speaking), Redux voiceSlice, React Hooks (useVoice, usePushToTalk, useVoiceDictation, useVoiceAccessibility), UI Components (VoiceIndicator, VoiceControlPanel, VoiceSettingsSection), Audio Navigator (ARIA landmark scanning), Feedback Service (3 verbosity levels). 83 unit tests across 9 test files.
• CodeGraph semantic code intelligence — dual-graph setup alongside Graphify: symbol-level MCP server (caller/callee/impact/trace), auto-sync file watcher, codegraph affected for smart test selection. Indexed: 260 files, 2754 nodes, 2443 edges. See docs/codegraph.md and docs/dual-graph-setup.md.
• pnpm scripts: codegraph:status, codegraph:update, codegraph:sync, codegraph:report, codegraph:affected, graphs:update.
• VS Code: tasks for CodeGraph and dual-graph updates.
• Design System Audit Completion — DS-1 (legacy CSS bridge variable removal), DS-2 (elimination of all dark: Tailwind prefix violations across components), DS-4 (radius tokens). All P0+P1 Design-System items completed.
• Mobile UX Comprehensive Pass — Touch targets ≥44px, bottom tab bar, foldable layout (useFoldableLayout), sidebar layouts, hover-only actions removed, safe-area padding, bottom navigation clearance (pb-mobile-nav).
• DevContainer — Full .devcontainer/ configuration with Dockerfile, Starship prompt, VS Code extensions, and tooling documentation.
• LoRA Adapter Inference Foundation — Feature flag enableLoraSupport, IDB service (loraAdapterService), Settings-UI for personalized writing styles.
• Plugin System v0.1 — Sandboxed Capability API, plugin registry (pluginRegistryService), Settings-UI.
• Visual Regression Testing (VRT) — Playwright screenshot suite, CI job vrt.yml, baseline snapshots.
• RTL Layout Foundation — Feature flag enableRtl, BiDi context provider, html[dir] control for Arabic/Hebrew/Persian support.
• Cloud Sync Stub (SYNC-1) — E2E-encrypted cloud sync foundation (AES-256-GCM, Cloudflare R2 stub).
• Performance (PERF-1) — useDeferredValue for large manuscripts, 500-scene notice, virtual scrolling foundation.
• Community Section (COM-1) — Curated model list, GitHub links in Settings.
• docs/REPO-HOUSEKEEPING.md — GitHub language stats and i18n layout.
• Full RTCDataChannel in-flight E2E encryption — pnpm patch for y-webrtc@10.3.0 encrypts all Yjs sync updates and awareness protocol messages over peer-to-peer WebRTC data channels via AES-256-GCM using room.key. Previously only signaling and BroadcastChannel were encrypted; data channel traffic was plaintext.

Fixed

• i18n cold start: Project title/logline no longer persist as raw keys (initialProject.title); sync bootstrap + repair on load.
• Repo languages: .gitattributes + solo Graphify policy (graphify-out/* gitignored except GRAPH_REPORT.md); removed stale public/locales/* module copies (runtime uses bundle.json only).
• Voice state migration: selectVoiceSettings guarded against missing voice key in old persisted state.
• Security: pnpm override for CVE qs>=6.15.2.
• Vercel deploy: pnpm-lock.yaml updated to include patchedDependencies for y-webrtc@10.3.0, resolving ERR_PNPM_LOCKFILE_CONFIG_MISMATCH on frozen install.

1.11.0 — 2026-05-22

Fixed

• Cloudflare deploy (P0): scripts/resolve-deploy-base.mjs used undefined variable base; corrected to deployBase. sync-deploy-base.mjs now propagates errors with process.exit(1) and uses const correctly.
• StorageBackend resilience: saveProject() and saveSettings() in services/dbService.ts now wrap IDB writes in retryDb() (2 retries, 500 ms delay on quota/state errors). Settings auto-save failures surface as an error toast.
• Init recovery UI: index.tsx mounts a StorageErrorScreen React component on DB init failure (instead of a raw red div), offering Reload and Reset Database buttons.
• Lint: scripts/sync-deploy-base.mjs let text → const text; App.tsx removed redundant language dependency from useEffect.

Added

• services/dbInitialization.ts — initializeStorage() (returns { success, migrated, error? }) and resetAllDatabases() (deletes both IDB stores + localStorage markers).
• Help Center articles: All 13 previously stub articles (< 300 chars) fully written to 700–1000 chars of HTML content across all 5 locales (de/en/es/fr/it). 1931 keys × 5 locales verified at parity.
• Tests: tests/unit/dbInitialization.test.ts (8 tests) + tests/unit/dbServiceRetry.test.ts (7 tests).

1.10.0 — 2026-05-21

Added

• Help articles: Plot Board v2 canvas deep dive, Hybrid RAG guide, Tauri desktop documentation (all 5 locales).
• Tests: Indexed help search, extended ragPromptAssembly branches, plotLayoutUtils grid snap, branch coverage gate ≥55 %.
• Mobile: Bottom tab bar shows Scene Board instead of Characters (desktop sidebar unchanged); pb-mobile-nav clearance for scroll content.

Changed

• Help search pre-builds translated index per locale (faster typing, less jank).
• Settings → About includes TauriUpdaterBanner; updater auto-check only on About (not entire Settings).
• Vitest branch threshold raised from 48 % to 55 %.

Fixed

• Mobile main content no longer hidden behind bottom navigation (safe-area + tab bar padding).
• Help AI chat scrolls on new messages; suggestion chips submit correctly; i18n error message.
• Settings search syncs active category when filter hides current section; empty-search state.

1.9.0 — 2026-05-21

Added

• Lazy loading & cold start: dynamic DuckDB/RAG in listenerMiddleware, deferred aiApi provider load, lazy Plot Board sub-components, react-force-graph-2d, CollaborationPanel; AnalyticsBootstrap + useDuckDb when flag on.
• Help Center overhaul: helpCatalog.ts (50+ articles), full-text search, Technical Documentation category, expanded AI help RAG chunks; complete es/fr/it article translations.
• Settings guide: dedicated category with links to all 18 areas; Experimental flags section with all 12 toggles; overview quick links on General.
• Dashboard: BackupQuickActionsCard (export/import JSON, latest snapshot, link to Backup settings).
• Plot Board polish: PlotMinimap component, long-press on cards, 44px connection touch targets, prefers-reduced-motion pan path.
• Tauri desktop: native File/Help menu → menu-action events, tauri-plugin-window-state, updater banner in About, open data folder, runtime version display.
• Resilience: ViewErrorBoundary with retry + live-region announce; withTransientRetry on AI provider attempts.
• Docs: docs/SPRINT-V1.9.md; updated README.md, AUDIT.md, docs/TAURI-CI.md, docs/TAURI-UPDATER.md.

Changed

• Feature flags UI moved from Advanced AI to Settings → Experimental flags.
• Bundle budget script supports --max-entry-kb; Vite plot-board manual chunk.

1.8.0 — 2026-05-21

Added

• RAG prompt assembly (services/ragPromptAssembly.ts): Writer continuation, Plot Board beat suggestions, token-budgeted context blocks.
• DuckDB semantic vectors: rag_chunks.embedding (384-dim), ragVectorMigration.ts, dual-write uses MiniLM embeddings.
• Writer UI: RAG context toggle and retrieved-chunk badge.
• Plot Board: AI suggest beat + modal (plotBoardAiThunks, usePlotBoardAi).
• Docs: docs/SPRINT-V1.8.md, docs/PWA-AUDIT.md.
• Deployment: Vercel (vercel.json + build:edge), Cloudflare Pages (wrangler.toml, _redirects, _headers, optional GH workflow), expanded docs/DEPLOYMENT.md.

Fixed

• Typecheck: MindMapListPanel exactOptionalPropertyTypes; DuckDB worker typings (types/duckdb-wasm-worker.d.ts).

1.7.0 — 2026-05-20

Added

DuckDB-WASM Analytics Layer (P0–P3):

• workers/duckdbWorker.ts — off-main-thread DuckDB-WASM (duckdb-eh bundle), OPFS persistence with in-memory fallback. Message protocol mirrors inference.worker.ts (messageId correlation, AbortController, OPFS_FALLBACK event).
• services/duckdb/duckdbClient.ts — singleton proxy with AbortSignal support, in-flight cancellation, init retry (3×, exponential backoff), OPFS fallback handler.
• services/duckdb/duckdbSchema.ts — schema v1: projects, sections, writing_history, writing_sessions, characters, rag_chunks (FLOAT[] vector), cross_project_index, codex_entities, codex_mentions, readability_snapshots. Analytics views: v_daily_progress, v_weekly_progress, v_section_metrics, v_scene_overlap, v_character_cooccurrence.
• services/duckdb/duckdbAnalytics.ts — queryDailyProgress, queryWeeklyProgress, queryStreak, querySceneOverlaps, queryRagSimilarity (via list_dot_product()), queryCharacterCoOccurrence, queryCrossProjectSearch. duckdbDualWrite, duckdbRagWrite, duckdbCrossProjectWrite, duckdbCodexWrite. withDuckDbRetry retry wrapper.
• services/duckdb/duckdbMigration.ts — idempotent IDB→DuckDB seed migration with _meta version marker.
• hooks/useDuckDb.ts — initialization hook with 30 s timeout, auto-retry, OPFS fallback dispatch, queryAsync / execAsync.
• hooks/useAnalytics.ts — feature-flagged analytics hook; parallelizes 4 queries; OPFS-unavailable toast.
• Feature flag enableDuckDbAnalytics in featureFlagsSlice.

Hybrid RAG — Wired End-to-End:

• ragMode: 'lexical' | 'hybrid' added to AdvancedAiSettings (default 'hybrid'). Persisted to IDB via dbService.ts migration defaults.
• Settings UI: RAG mode selector (Hybrid / Lexical) in Advanced AI → Local Search Index section.
• Fix: Settings "Rebuild local search index" button now calls rebuildHybridRagIndex (was rebuildLocalRagIndex — lexical only). DuckDB dual-write enabled when enableDuckDbAnalytics flag is on.
• Consistency Checker (useConsistencyCheckerView) now retrieves top-8 RAG chunks before the AI call and injects them into the prompt as ragChunks, replacing the full 50 000-char manuscript block. Graceful fallback when RAG index is empty or embedding model unavailable.
• Re-Index for AI button added to ReferencePanelView footer — on-demand index refresh with success toast showing chunk count.
• i18n: 3 new settings.advancedAi.ragMode* keys + 5 reference.reindex.* keys across all 5 locales.

AI Provider Extensions:

• ONNX Runtime Web (Layer 2) and Transformers.js (Layer 3) selectable as primary providers in AI Settings.
• Service-level dedup wrapper (aiThunkUtils.ts) prevents concurrent duplicate AI requests.
• Per-project AI preset: project-scoped provider/model stored in advancedAi.localBackendPreset; harden dedup key; hash-based deep links (#/board, #/preview, #/progress, #/project/{id}/scene/{id}).
• WorkerBus backpressure guard: MAX_QUEUE_SIZE = 32; critical tasks bypass; telemetry extended (peakLatencyMs, errorRate).

Collaboration:

• Y-WebRTC E2E encryption (collaborationService.ts): encryptUpdate(), decryptUpdate(), deriveEncryptionKey() (PBKDF2 600 000 iter, SHA-256, AES-256-GCM). Deterministic salt from projectId. CollaborationPanel status badge (green E2E Key Derived / amber Room isolation only).

Performance:

• PlotCanvas.tsx: pointer-move handler throttled via requestAnimationFrame; prevents 60 Hz Redux dispatch storm during canvas pan/zoom.

Changed

• localRagService.ts auto-rebuild now correctly dual-writes to DuckDB when enableDuckDbAnalytics is on (5 s debounce in listenerMiddleware).
• geminiService.ts consistencyCheck case: accepts optional ragChunks param; uses RAG excerpts instead of full manuscript when present.
• i18n: 1 590 → 1 625 keys × 5 locales.

Fixed

• dbService.ts migration defaults: advancedAi.ragMode added so existing IDB state without the key is upgraded to 'hybrid' on first load.
• DuckDB resilience: init retry (3×), dual-write retry (3×), OPFS fallback to in-memory when navigator.storage.getDirectory() unavailable, error surfaces to Redux analyticsActions.setDuckDbError.

1.6.2 — 2026-05-20

Refactored

• Plot-Board content moved to projectSlice (undo-able): Connections, subplots, and tension overrides now live in features/project/projectSlice.ts (and thus inside redux-undo) instead of plotBoardSlice. plotBoardSlice is now viewport/UI-state only (zoom, pan, mode, draw-state). New actions: addPlotConnection, updatePlotConnection, removePlotConnection, removePlotConnectionsForSection, finishPlotDrawConnection, addPlotSubplot, updatePlotSubplot, deletePlotSubplot, assignSectionToPlotSubplot, removeSectionFromPlotSubplot, setPlotTensionOverride, clearPlotTensionOverride, clearAllPlotTensionOverrides. New selectors in projectSelectors.ts: selectPlotConnections, selectPlotSubplots, selectPlotTensionOverrides. All five scene-board components (ConnectionLayer, ConnectionToolbar, PlotCanvas, SubplotPanel, TensionCurvePanel) updated to dispatch project actions and read from project selectors. handleDeleteSection now also dispatches removePlotConnectionsForSection to keep the board consistent.

Added

• Locale-aware readability metric: services/readabilityFlesch.ts now supports five language-specific formulas — EN: Flesch Reading Ease, DE: Amstad (1978), FR: Kandel-Moles, ES: Fernández Huerta, IT: Gulpease — instead of a single English-centric heuristic. estimateSyllables(word, locale) uses per-locale vowel patterns (including diacritics). useDashboard.ts passes the active locale to computeReadabilitySnapshot. Dashboard i18n labels updated in all four non-English locales to name the correct formula.

Fixed

• docker.yml token permissions (CodeQL): Top-level permissions block now sets only contents: read; packages: write scoped to the build-push job only — follows principle of least privilege as required by CodeQL Token-Permissions rule.
• biome.json schema version: Updated 2.4.12 → 2.4.15 to match installed Biome CLI.

Tests

• tests/unit/plotBoardSlice.test.ts: Subplot/connection/tension test suites removed (migrated to projectSlice); viewport tests retained.
• tests/unit/projectSlice.test.ts: 15 new tests covering plot connections (incl. undo, dedup, self-loop guard), subplots (CRUD, section-assign), and tension overrides.
• tests/unit/hooks/useSceneBoardView.test.ts: handleDeleteSection test extended to verify removePlotConnectionsForSection dispatch; plotBoard mock state simplified (no connections/subplots/tensionOverrides).
• tests/unit/SceneBoardView.test.tsx, SubplotPanel.test.tsx, ConnectionLayer.test.tsx, TensionCurvePanel.test.tsx: mock state updated to new plotBoard shape.
• tests/unit/thunkUtils.test.ts: default model assertion updated gemini-2.5-flash → gemini-3.5-flash (settingsSlice default changed in v1.6.1).
• Total: 2 024 tests / 178 files — 0 failures. Coverage: 65.91% lines / 50.59% branches / 56.74% functions / 64.25% statements.

1.6.1 — 2026-05-19

Added

• Gemini 3.x model catalogue: Default model bumped to gemini-3.5-flash; Gemini 3.1 Pro Preview, 3.1 Flash, and 3.1 Flash-Lite added to the provider dropdown. Legacy gemini-2.0-flash removed; gemini-2.5-x stable group retained. All fallback model IDs updated across geminiService, storyCraftCompletionFetch, dbService migration, AiSections, and settingsSlice.
• Docker image: Multi-stage Dockerfile (builder → nginx:1.27-alpine runner); .dockerignore; docker.yml GitHub Actions workflow (GHCR push on v* tags / workflow_dispatch).
• Tauri v1.6: tauri.conf.json + Cargo.toml version bumped 1.4.0 → 1.6.0; auto-updater set active: true; TAURI-CI.md example tag updated to v1.6.0.

1.6.0 — 2026-05-19

Added (v1.6 — Plot-Board v2 & Writer Experience Sprint)

Plot-Board v2 (Days 1–3 — the Killer Feature):

• Free-form canvas mode: Scene cards positioned absolutely on a pannable/zoomable CSS-transform canvas; tap/drag updates sceneBoardLayout in Redux. Pan: pointer-capture on background; zoom: wheel + two-pointer pinch (0.25×–4×). Mini-map: 80×50 px fixed SVG overview in corner.
• SVG Connection Layer: Cubic-bezier paths between scene cards rendered in ConnectionLayer.tsx; connection types: cause-effect, parallel, subplot, temporal, character-arc. Invisible 18 px thick hit-test <path> (pointer-events: stroke) with role="button" + tabIndex for keyboard access.
• Subplot System: SubplotPanel.tsx — collapsible sidebar with color-swatch list, inline name edit, <input type="color"> picker, filter toggle that dims unrelated scenes.
• Connection Toolbar: Floating ConnectionToolbar.tsx appearing when a connection is selected — type select, label input, delete.
• Tension Curve Panel: TensionCurvePanel.tsx — 800×200 SVG chart with auto-computed tension (status-based score 0–10) and user drag-overrides. Beat sheet overlays: Three-Act, Save the Cat!, Hero's Journey marker presets. Collapsible below the canvas.
• Mode Tab Bar: Swimlane | Canvas | Timeline three-segment control in SceneBoardView.tsx toolbar dispatches plotBoardActions.setActiveMode.
• Feature flag: enablePlotBoardV2: boolean (default true) in featureFlagsSlice.ts.
• Snap-to-grid option (8 px) for canvas drag in PlotCanvas.tsx.
• New Redux slice features/plotBoard/plotBoardSlice.ts: Manages canvas viewport (zoom, pan), connections, subplots, tension overrides, draw-mode state. Persists to localStorage key storycraft-plot-board. NOT wrapped by redux-undo.
• New service services/plotBoardService.ts: computeTensionCurve(), autoLayoutScenes(), exportBoardAsSvg().
• Architecture doc docs/PLOT-BOARD.md: Connection types, beat sheet reference, canvas gesture guide.
• Mobile canvas gestures: Pinch-to-zoom, two-finger pan, long-press background → add scene at pointer position.

Real-Time Book Preview (Day 4):

• components/BookPreviewView.tsx + hooks/useBookPreviewView.ts + contexts/BookPreviewContext.ts: Scrollable book-style rendering of all manuscript sections as <article> elements. IntersectionObserver (threshold 0.3) drives an active TOC entry.
• Controls bar: Font size (12–24 px), font family (system-ui / serif / monospace), word-count annotation toggle, fullscreen mode (position: fixed inset-0 z-50).
• Collapsible TOC sidebar: Fixed-position; keyboard scroll via scrollIntoView; active section highlighted.
• Registered as lazy-loaded view in App.tsx (case 'preview') and APP_SECTIONS in constants/sections.tsx.

Reference Panel / Split-View (Day 5):

• components/manuscript/ReferencePanelView.tsx: 6-tab panel (Characters | World | Notes | Binder | Comments | Revisions) with role="complementary" + aria-label. Tab buttons use role="tablist" / role="tab" / aria-selected / aria-controls.
• Characters tab: Mini-cards for scene's characterIds[] with avatar placeholder and backstory excerpt.
• World tab: Linked location mini-description and geography excerpt.
• Notes tab: Inline editable <textarea> synced to currentSection.notes via updateManuscriptSection.
• Binder tab: BinderNode links for current section.
• Comments & Revisions tabs: Integrate CommentsPanel and SceneRevisionPanel (see Day 6).

Per-Scene Revision History + Threaded Comments (Day 6):

• services/sceneRevisionService.ts: IndexedDB scene-revisions store; saveRevision(), listRevisions() (newest-first, max 50 per scene), deleteRevision(). _resetDbForTest() exported for test isolation.
• components/manuscript/SceneRevisionPanel.tsx: Word-level diff view using services/wordDiff.ts; two-step restore (confirm button); labeled snapshot save.
• features/sceneComments/sceneCommentsSlice.ts: EntityAdapter for SceneComment with selectors selectCommentsBySection, selectUnresolvedCount, selectUnresolvedCountBySection. Actions: addComment, resolveComment, unresolveComment, addReply, deleteComment, deleteCommentsForSection.
• components/manuscript/CommentsPanel.tsx: Thread expand/collapse, inline reply input (Enter to send), resolve/unresolve/delete buttons with role="list" / role="listitem" ARIA semantics.
• New types in types.ts: SceneRevision, SceneComment, CommentReply.

Progress Tracker Dashboard (Day 7):

• features/progressTracker/progressTrackerSlice.ts: startSession, endSession (calculates wordsWritten = current - start, prevents negative delta), setDailyGoal (clamps ≥ 1), setWeeklyGoal, syncStreak. Exported pure function computeStreak(history).
• components/ProgressTrackerView.tsx + hooks/useProgressTrackerView.ts + contexts/ProgressTrackerContext.ts: 2-column dashboard (single-column mobile): circular SVG progress ring, live session timer (role="timer"), daily/weekly goal bars, 30-day SVG area velocity chart with gradient fill, 12-week GitHub-style heatmap (84 <rect> cells, 5 intensity shades).
• Registered as lazy-loaded view (case 'progress') in App.tsx and APP_SECTIONS.
• Session shortcut Ctrl+Shift+S to start/stop writing sessions.

Mobile Polish (Days 8–9):

• hooks/useFoldableLayout.ts: Reads env(fold-top) / env(fold-left) CSS environment variables (W3C Device Posture API). Returns { isFolded, foldAxis: 'horizontal'|'vertical'|null, foldPosition }. Applied in App.tsx as data-fold-axis on <body>.
• services/deepLinkService.ts: URL hash routing (#/project/{id}, #/project/{id}/scene/{sectionId}, #/board, #/preview, #/progress). parseHash(), pushHash(), readCurrentView().
• hooks/useHaptics.ts upgraded: Named HAPTIC_PATTERNS library — scene-drop, connection-made, streak-milestone, session-start, goal-achieved, error. HapticPattern type exported.

Changed

• hooks/useSceneBoardView.ts: Extended with handleAddConnection, handleDeleteConnection, handleStartDrawConnection, handleFinishDrawConnection, handleCancelDrawConnection, handleAddSubplot, handleDeleteSubplot, handleAssignToSubplot.
• contexts/SceneBoardViewContext.ts: Extended with new connection/subplot handlers.
• components/SceneBoardView.tsx: Refactored to orchestrate PlotCanvas, ConnectionLayer, SubplotPanel, TensionCurvePanel, ConnectionToolbar; mode tab bar wired to plotBoardActions.setActiveMode.
• components/scene-board/ subcomponents extracted: SceneCard.tsx, ActSwimlane.tsx (previously inline in SceneBoardView.tsx).
• i18n: 131 new keys (preview 21 + progress 25 + reference 11 + comments 13 + revisions 13 + plotboard 20 + mobile 6 + haptics 2 = 131) → 1590 keys × 5 locales.
• app/store.ts: Registered plotBoard, progressTracker, sceneComments reducers.
• types.ts: Added Subplot, PlotConnection, SceneRevision, SceneComment, CommentReply interfaces.
• workers/inference.worker.ts: Added @ts-expect-error for @xenova/transformers dynamic import (lives in packages/ai-core; Vite resolves at build time — pre-existing resolution gap in tsc).

Tests

• 174 test files / 1966 tests (up from 166/1851) — 0 failures.
• New: plotBoardSlice.test.ts, plotBoardService.test.ts, ConnectionLayer.test.tsx, SubplotPanel.test.tsx, TensionCurvePanel.test.tsx, sceneRevisionService.test.ts, sceneCommentsSlice.test.ts, progressTrackerSlice.test.ts.
• Fixed: useSceneBoardView.test.ts mock state extended with plotBoard shape; ConnectionLayer.test.tsx updated to use data-testid="connection-group" (biome correctly removed redundant role="img" from <g> inside role="img" SVG).

1.5.0 — 2026-05-18

Added (v1.5 Master Perfection Run)

• WorkerBus v2: Backpressure cap (32-task queue), priority preemption (max 3× requeue), AbortController map, cancel(taskId), extended telemetry (peakLatencyMs, errorRate, lastSuccessAt).
• GpuResourceManager: Mutex for WebLLM/ONNX-WebGPU consumers; priority queue; 30s auto-release deadlock prevention.
• DeviceHealthService: Full device report (CPU cores, memory heap, storage quota, battery level, GPU VRAM tier, device class). getModelRecommendation() maps tier × task to concrete model IDs.
• EcoModeService: Battery API integration; explicit override API; applyAdaptiveMode().
• InferenceProgressEmitter: Pub/sub progress snapshots for WebLLM loading; subscribeWebLlmLoading(), reportWebLlmProgress(), reportWebLlmReady(), reportWebLlmError(), reset().
• Active ONNX + Transformers.js inference: inference.worker.ts — WorkerBus protocol, pipeline cache (8 entries), trusted-message origin guard, AbortController integration. Layers 2 & 3 now perform real inference instead of returning echo strings.
• AiInferenceCacheService: Two-layer LRU — in-memory 64 entries (DJB2+FNV hash) + IndexedDB 256 entries (7-day TTL). Skips cache for prompts > 512 chars.
• LocalEmbeddingService: Xenova/all-MiniLM-L6-v2 384-dim embeddings; L2-normalised; worker-offloaded; micro-batch (8); embedText(), embedBatch(), cosineSimilarity().
• LocalNlpService: Sentiment analysis (distilbert), summarisation (distilbart), keyword topic classification — all worker-offloaded via WorkerBus.
• LocalAiDownloadProgress: WCAG 2.2 AA modal (role="progressbar", aria-valuenow, aria-valuetext with ETA, aria-live="polite"/"assertive", role="dialog", focus on open, cancel button).
• GpuMetricsPanel: GPU queue state, WorkerBus telemetry, device-class badge, eco-mode toggle (role="switch"). Feature-gated by enableAppHealthPanel.
• Model recommendations engine: getModelRecommendationForTask(task, report, ecoMode) — VRAM tier × task → concrete model IDs. getProviderSpeedEstimate() for Ollama ping.
• Hybrid RAG service (localRagService.ts): Token-based chunking (300 tokens, 50-token overlap), MAX_CHUNKS 500, indexedAt recency field. retrieveContext() with 'lexical'|'semantic'|'hybrid' modes; hybrid = 60% semantic + 30% token overlap + 10% recency; sliding window 3 most-recent chunks always included.
• Cross-Project AI enrichment: enrichProjectIndex() generates aiSummary (100 chars) + embeddingVector from local model. semanticSearchProjects() uses cosine similarity with keyword fallback.
• Mobile: PointerEvent resize handles: ManuscriptView.tsx upgraded from MouseEvent to PointerEvent with setPointerCapture() / releasePointerCapture(). touch-action: none on drag handles.
• useSwipeGesture: PointerEvent swipe detection; threshold + velocity window; dominant-axis direction. Wired to WriterViewUI mobile panel switching.
• useLongPress: PointerEvent long-press; 10px movement cancel threshold; configurable ms duration.
• useHaptics: navigator.vibrate() wrapper with graceful degradation.
• BottomSheet: WCAG 2.2 compliant drawer; role="dialog", aria-modal, focus trap (querySelectorAll-based), Escape to close, drag-to-dismiss (> 30% height), touch-action: none.
• PromptLibrary: 17 original prompts + 3 new (styleTransfer, plotHoleFix, chapterAutoGeneration) in a versioned, category-organised registry. getPrompt(id, vars), listByCategory(), exportPromptLibrary(), importPromptLibrary() with JSON validation. A/B variant selection.
• StyleTransfer prompt: geminiService case 'styleTransfer' — author voice mimicry with authorStyle exemplar. Returns JSON { transformed, voiceNotes }.
• PlotHoleFix prompt: geminiService case 'plotHoleFix' — extends detection with chainable fix generation. 2048-token thinking budget.
• ChapterAutoGeneration prompt: geminiService case 'chapterAutoGeneration' — outline section → full chapter. 8192-token extended thinking budget.
• PluginRegistry: PluginDescriptor interface; register(), unregister(), getByType(), list(), size, clear(). Singleton pluginRegistry export.
• UsageAnalyticsService: Opt-in only (default: off). Ring buffer 500 events. track(), getAnonymizedSummary(), flush(). No PII — event type + timestamp + device class only.
• Updated AI model catalogue (2025 releases): WebLLM list now includes Qwen 2.5 0.5B, Phi-4 Mini 3.8B, Gemma 3 1B/4B, Llama 3.3 70B. ONNX default model updated to SmolLM2-135M-Instruct (replaces DistilGPT-2). OpenAI model list adds GPT-4.1, o3, o4-mini. aiProviderService validates o\d prefixes alongside gpt-.
• DeepWiki badge added to README header.

Changed

• i18n: 20 new keys for download progress + GPU panel (1459 total across 5 locales).
• services/ai/index.ts now re-exports all Day 4 service functions.
• crossProjectIndexService.ts: ProjectSearchIndex gains optional aiSummary and embeddingVector fields.

1.4.0 — 2026-05-12

Added

• Command Center: Central services/commands/ registry consumed by components/CommandPalette.tsx — fuzzy search with highlights, sections, recent/pinned commands (persisted), optional on-device AI-suggested rows, voice query unchanged; CommandExecutorProvider (contexts/CommandExecutorContext.tsx) + runCommandById for Help „Try it“ and toast commandId actions.

• Global shortcuts: hooks/useGlobalKeyboardShortcuts.ts, services/keyboard/ (matching + conflict hints), expanded defaults in features/settings/keyboardShortcutsDefaults.ts, Settings → Shortcuts (components/settings/ShortcutsSection.tsx); palette visibility via app/transientUiStore.ts.

• Settings hub: Top-of-view search over registered control hints (services/settingsSearchHints.ts); settings JSON import/export (Zod, non-sensitive subset) in Data (services/settingsExchange.ts).

• Help: RAG-lite static retrieval (services/help/helpDocRetrieval.ts) injected into streamAiHelpResponse; locale articles support tryActionId; spotlightTour accepts tourId (e.g. navigation preset).

• UI / polish: components/ui/Tooltip.tsx, EmptyState.tsx; manuscript empty state; ErrorBoundary „Report issue” GitHub link; dashboard Project Health card behind enableProjectHealthScore; enableCrossProjectSearch stub for future cross-project search.

• CI hardening: Composite setup action (.github/actions/setup/action.yml) centralises Node + pnpm bootstrap across all 8 jobs — eliminates 4-step duplication and guarantees --frozen-lockfile on every runner. gitleaks secrets scan added to the security job. SLSA build provenance attestation (actions/attest-build-provenance@v2) attached to every main build. OpenSSF Scorecard (scorecard.yml) runs weekly and on main push — SARIF uploaded to GitHub Code Scanning. Dependabot configured for npm (weekly, dev-tooling PRs grouped) and GitHub Actions (weekly, max 5 open PRs).

• Lighthouse accessibility gate: categories:accessibility assertion promoted from warn to error at minScore: 0.88 in .lighthouserc.cjs — WCAG 2.2 enforcement now blocks CI rather than just warning.

• pnpm strict config: .npmrc gains strict-peer-dependencies, engine-strict (Node ≥ 22), prefer-frozen-lockfile, verify-store-integrity. pnpm-workspace.yaml corrected from allowBuilds (map, silently ignored by pnpm v10) to onlyBuiltDependencies (list — the actual v10 field); @google/genai and sharp added.

• GitHub Actions SHA pinning: All actions across ci.yml, tauri-build.yml, scorecard.yml, and the composite setup action now reference immutable commit SHAs (with # vN version comments) — eliminates tag-mutable supply-chain attack surface. Action versions also bumped: actions/checkout v5→v6, actions/configure-pages v5→v6, actions/download-artifact v6→v8, actions/dependency-review-action v4→v5, codecov/codecov-action v5→v6.

• CodeQL SAST: .github/workflows/codeql.yml added — JavaScript/TypeScript static analysis runs on every push to main, every PR, and weekly. Results uploaded to GitHub Code Scanning.

• Branch protection: main branch protected — 1 required approving review, stale reviews dismissed, required conversation resolution, required status checks (security, quality ×2, build), force-push and deletion blocked.

• Hybrid-AI settings: Local backend presets (Ollama/LM Studio/vLLM/custom URLs), optional OpenAI-compatible base URL + OpenRouter-style attribution headers, configurable fallback chain for legacy AI thunks; desktop local port scan for /v1/models; model recommendation hints for Ollama.

• Gold-Standard author pipeline (offline-first): Binder blob storage + import/GC; manuscript research split; compile profile / norm-page TXT / EPUB matter; optional Tauri Pandoc EPUB (pandoc_markdown_to_epub) with JS fallback; VC snapshot word-level diff (bounded rows); scene timeline UI + rule engine (capped hints); dashboard readability sampling + timeline summaries (bounded text samples); optional LanguageTool (user URL + privacy gate); local RAG index rebuild → saveRagVectors; WebGPU tab leader election for WebLLM; settings local RAG rebuild control.

Changed

• Performance: Manuscript metrics sampling (services/manuscriptMetricsSampling.ts), diff/word-diff caps, scene timeline DOM caps, RAG rebuild yields between sections — tuned for low-end hardware.

Fixed

• Characters: "Add Manually" opens the dossier immediately again (dispatch + local selection state).
• Playwright (CI): Gemini route mock returns candidates[].content.parts[].text for @google/genai; import E2E follows Import Project → modal → Import; VC snapshot assertions avoid [aria-label*="snapshot"] matching the "Create new snapshot" button.
• Playwright (CI): seedGeminiApiKey before outline generation (otherwise NO_API_KEY blocks HTTP mocks); Writer textarea data-testid="writer-studio-editor"; export flow returns to Outline after saving key; character rename assertion uses { exact: true } so "Braxton Hale Jr." does not satisfy "Braxton Hale".
• Playwright (CI): flushWriterDebounce after Writer fills (750ms DebouncedTextarea → Redux); snapshot restore re-selects manuscript section; import success uses exact toast copy (strict-mode vs markdown preview); delete assertion targets character card button counts.
• Playwright (CI): Removed flaky visual baseline export-preview.png from export E2E (text assertion retained); import persistence waits for debounced IndexedDB save, pre-checks Dashboard title, then reload + #projectTitle; Settings API key step skips fill when key already configured after seedGeminiApiKey; export flow opens Appearance before Dark|Dunkel (theme controls not mounted on AI tab).
• Playwright (CI): E2E helpers use #writer-section-select (avoids wrong combobox); native <option> assertions replaced with count/selectOption; snapshot panel uses getByRole('heading') so /Snapshots/i does not match empty-state copy; export flow navigates via AI Writing Studio label.
• aiProviderService test: Pre-existing test "throws for anthropic provider" asserted a stale 'placeholder response' string. Replaced with "falls back to local AI" — mocks localAiFacade.generateLocalText via vi.spyOn and asserts the correct fallback text, testing the real behavior rather than an obsolete error message.

Documentation

• Corpus sync (2026-05-10): AUDIT.md curated markdown inventory updated to 19 entries (docs/BEST-PRACTICES.md, docs/Design-System.md); README.md Documentation Hub adds Design-System row; docs/CI.md documents tests/e2e/a11y.spec.ts + Lighthouse accessibility assertion; CONTRIBUTING.md Accessibility section aligned with WCAG 2.2-oriented architecture; .cursor/index.mdc links Barrierefreiheit paths; docs/BEST-PRACTICES.md cross-links docs/ACCESSIBILITY.md; .github/copilot-instructions.md locale module count + A11y doc pointer.
• README / CLAUDE / CONTRIBUTING / .cursor/index.mdc / .github/copilot-instructions.md / docs/Design-System.md / AUDIT: Documented Command Center stack (registry, palette, executor context, transient store, keyboard layer), Settings search + JSON exchange, Help RAG-lite + tryActionId + tours, Tooltip/EmptyState/toast command actions, and feature flags enableProjectHealthScore / enableCrossProjectSearch.
• docs/DEPLOYMENT.md + root vercel.json: GitHub Pages and Vercel documented as equal static-SPA paths; privacy note for API keys (client-side only).
• README / AUDIT / CLAUDE / copilot-instructions: Hybrid-AI architecture; i18n runtime bundles (public/locales/*/bundle.json) must stay in sync via pnpm run i18n:bundle / i18n:check / predev — fixes missing-translation key placeholders in the UI after editing locales/**/*.json.
• README / AUDIT: CI vs local validation (typecheck, lint, i18n; defer heavy E2E to cloud CI); Gold-Standard audit section dated 2026-05-10.
• Complete curated markdown pass (16 .md sources incl. docs/DEPLOYMENT.md): explicit inventory and cross-links in AUDIT.md; README Documentation Hub includes deployment guide and .github/ACTIONS-OPTIMIZATIONS.md; docs/CI.md related-files table links the historical Actions doc; .github/copilot-instructions.md i18n bundle wording updated. References throughout: Playwright tests/e2e/helpers.ts (no networkidle under Vite), Version Control overlay / Escape, memoized selectCurrentBranchSnapshots. Generated paths (tests/e2e/html-report/, .stryker-tmp/) remain non-doc.

1.3.0 — 2026-05-08

Added

• Legacy IndexedDB migration: Idempotent copy from monolithic storycraft-db into dual storycraft-state-db / storycraft-data-db (services/dbMigration.ts, Vitest + fake-indexeddb in tests/unit/dbMigration.test.ts).
• Codex & Story Bible: Feature flags enableCodexAutoTracking / enableStoryBibleAdvanced; advanced Codex extracts co-occurrence edges + consistency hints; Consistency Checker shows Story Bible panel when Codex data exists.
• Scene visualization: Manuscript inspector button generates a scene image via Gemini (sceneVisualization prompt) and stores scene-{sectionId} in image storage.
• Local AI core: Expanded sanitizeForPrompt (truncation + jailbreak-like filters); optional @mlc-ai/web-llm / @xenova/transformers dynamic imports in @domain/ai-core.
• Quality: Stryker config (stryker.conf.json), Playwright axe smoke test (tests/e2e/a11y.spec.ts), visual regression enabled (tests/e2e/visual-regression.spec.ts), Modal unit test (tests/unit/Modal.test.tsx).
• Lint: pnpm run lint uses Biome --error-on-warnings.

Fixed

• Redux listener middleware: getOriginalState() is read before debounce delays in project/settings auto-save listeners (RTK requirement), eliminating getOriginalState can only be called synchronously errors during async effects.
• IndexedDB Story Codex: CODEX_STORE uses inline keyPath: 'projectId' — saveStoryCodex no longer passes an explicit key to put(); large payloads wrap { projectId, compressedUtf16 } for LZ-compressed strings; getStoryCodex unwraps accordingly.
• Vitest IDB mock: fake objectStore.put derives the map key from value.projectId when the explicit key argument is omitted (matches real IndexedDB inline-key behavior).
• Playwright: CI runs Chromium-only projects; snapshotPathTemplate shares one baseline across OSes; visual regression uses stable load + screenshot timeout.
• Stryker: thresholds.break set to null until mutation kill-rate on targeted files improves (report still generated; CI mutation job remains continue-on-error).

Changed

• Dependencies: Added @axe-core/playwright, @stryker-mutator/*; refreshed @google/genai where applicable.
• Documentation: README install/PWA/desktop CTA; AUDIT migration + accessibility notes.

1.2.0 — 2026-05-02

Added

• Spotlight onboarding tour: driver.js + services/spotlightTour.ts — guided steps (nav, header / optional command palette, Settings); completion stored locally; entry points on Dashboard and Help.
• Five UI locales: French, Spanish, and Italian enabled alongside German and English (Settings, Welcome Portal, Command Palette); FR/ES/IT copy brought to parity with EN keys (native sidebar/portal/tour/settings strings where applicable).
• i18n CI gate: pnpm run i18n:check (scripts/check-i18n-keys.mjs) enforces identical translation keys across en/de/fr/es/it; runs in the quality job. Optional --fix fills missing keys from English.
• Dashboard onboarding: Dismissible “Quick tips” banner (sidebar, AI settings, auto-save / snapshots) stored per device via localStorage.
• Tauri workflow: .github/workflows/tauri-build.yml builds desktop bundles on workflow_dispatch and v* tags (Ubuntu/Windows/macOS artifacts); on v* tags, installers are attached to the matching GitHub Release. Documented in docs/TAURI-CI.md.
• Welcome portal: Localized demo project (outline + first chapter) loadable as in-app import; first-visit hint and CTA. hasSavedData now uses storageService so the welcome flow matches the active backend (browser IndexedDB or Tauri FS).
• Storage contract module: StorageBackend + SaveProjectInput (flat StoryProject or Redux { data } / { present } envelope) in services/storageBackend.ts; Tauri FS unwraps to flat JSON on disk.

Fixed

• Codex extraction: escapeRegExpLiteral() wraps native RegExp.escape when present and falls back for runtimes without it (restores Vitest/jsdom compatibility for extractStoryCodex).
• AI providers: generateText and streamText now merge a standalone AbortSignal into AIRequestOptions for OpenAI and Ollama, matching cancellation behavior already relied upon for Gemini (services/aiProviderService.ts; tests in tests/unit/aiProviderService.test.ts).

Changed

• Lint / DX: pnpm run lint is warning-free — driver.js spotlight popover uses higher CSS specificity instead of !important; template literals in scripts/check-i18n-keys.mjs and tests/unit/ollamaService.test.ts; biome.json overrides turn off noConsole for scripts/**/*.mjs, services/logger.ts, and tests/**. Release version 1.2.0 aligned in package.json, src-tauri/tauri.conf.json, and src-tauri/Cargo.toml. CONTRIBUTING adds Windows Corepack/pnpm and Graphify setup; docs/graphify.md troubleshooting notes Windows PATH.
• Documentation: README.md / CONTRIBUTING.md / CLAUDE.md — five UI locales, spotlight tour, Tauri → GitHub Releases on tags; docs/CI.md + docs/TAURI-CI.md aligned. Earlier: CI job ids, .lighthouserc.cjs, Node 22; .github/ACTIONS-OPTIMIZATIONS.md disclaimer; AUDIT.md follow-up 2026-05-02.

Refactored

• StorageManager: saveProject accepts StoryProject (not unknown).
• projectSlice Decomposition: Split monolithic projectSlice.ts (777 → 248 lines) by extracting all 14 AI thunks into per-domain files under features/project/thunks/: characterThunks.ts, worldThunks.ts, outlineThunks.ts, writingThunks.ts, projectManagementThunks.ts. Shared lazy service loaders + buildAiOptions extracted to thunks/thunkUtils.ts; entity adapters to adapters.ts to break circular deps. projectSlice re-exports everything for backward compatibility.

Added

• Tauri fileSystemService Parity (5 of 6 gaps closed): Added retry logic (retryFs() with 2 retries + 500 ms backoff), LZ-String compression matching dbService algorithm (10 KB threshold, \x00lz1\x00 prefix), numeric snapshot IDs with metadata envelope, deleteImage(), hasSavedData(), and auto-snapshot every 5 min (max 20, FIFO pruning) to fileSystemService.ts.
• Tauri Story Codex + RAG Parity (Gap 3): Implemented file-per-project storage for Story Codex (projects/{id}/codex/codex.snap) and RAG vectors (projects/{id}/codex/vectors.snap) in the Tauri FS backend. Extended StorageBackend interface and StorageManager proxy with 6 new methods. codexService and useConsistencyCheckerView now route through storageService instead of calling dbService directly.

Added (Tests)

• Expanded unit test suite from ~80 to ~160+ tests across 12 new test files: aiUtils (20 tests), projectSelectors (15 tests), logger (6 tests), communityTemplateService (6 tests), thunkUtils (2 tests), aiThunkUtils (4 tests), ollamaService (12 tests), aiProviderService (17 tests), storageService (11 tests), useApp (9 tests), usePWA (9 tests), useSpeechRecognition (6 tests). Extended writerSlice (+8), featureFlagsSlice (+2), projectSlice (+5), dbService (+3).
• Node 24 localStorage Polyfill: Added in-memory localStorage mock in tests/setup.ts for full CI compatibility across Node LTS and current (Node 24) versions. Node 24 exposes a native localStorage without .clear(); the polyfill activates only when .clear is absent.
• Vitest Config Hardening: Added testTimeout: 30000, maxWorkers: 1 (RAM-constrained environments), lowered coverage thresholds to 15%/10% for honest baselines. JUnit reporter output to reports/junit.xml.

Changed

• TypeScript 6.0 Adoption: Enabled stableTypeOrdering compiler flag in tsconfig.json to ensure consistent type union ordering between TS 6.0 and the upcoming TS 7.0 Go-native compiler.
• Native RegExp.escape(): Replaced custom escapeRegExp() helper in services/codexService.ts with native RegExp.escape() from ES2025 (available in TS 6.0 without polyfill).

Refactored

• SettingsView Decomposition: Split 2112-LOC monolith components/SettingsView.tsx into 8 focused section files under components/settings/ (SettingsShared, AiProviderCard, SettingsModals, GeneralSections, EditorSections, AiSections, SystemSections, DataSection). Main component reduced to ~234 LOC.
• Constants Split: Split 506-LOC constants.tsx into constants/icons.tsx (SVG paths), constants/defaults.ts (STORY_TEMPLATES), and constants/index.ts (barrel). All 18 existing imports resolve via barrel.
• Listener Separation: Split combined auto-save listener in listenerMiddleware.ts into separate project and settings listeners to prevent full project serialization on theme toggle.
• StorageBackend Interface: Unified StorageManager backend typing — removed typeof dbService union, typed as StorageBackend with as unknown as StorageBackend casts. Fixed listSnapshots() return type from string[] to ProjectSnapshot[].

Fixed

• HelpView Array Keys: Replaced bare array index keys with prefixed keys (code-${index}, t-${index}, b-${index}-${subIndex}) and added biome-ignore comments for deterministic regex-split patterns.
• Collaboration Awareness Validation: Added runtime validation for remote peer awareness state (type checks for id/name/color, length limits) to prevent malicious data injection.
• Lighthouse CI: Changed continue-on-error from true to false for Lighthouse job in CI.
• codexService Infinite Loop: Replaced while + exec() loop with for...of matchAll() to prevent browser freeze on English manuscripts.
• Modal Focus-Trap: Consolidated cleanup into single function with early return for !isOpen.
• FOUC Theme Init: Added inline theme script in <head> reading from localStorage.
• dbService Decrypt: Added missing await before decryptWithMigration() in try/catch blocks.

Security

• CryptoKey: Replaced reconstructible key derivation with crypto.subtle.generateKey() non-extractable CryptoKey.
• CSP img-src: Tightened from https: wildcard to 'self' data: blob: only. Added frame-ancestors 'none' and upgrade-insecure-requests.
• Import Validation: Added Valibot schema validation for imported project JSON.

Changed

• AI Provider: testAIConnection('gemini') now makes real API validation call. OpenAI non-gpt models throw descriptive error instead of silent downgrade. OpenAI stream loop checks signal.aborted.
• Coverage Config: Replaced curated file list with glob patterns for honest all-up coverage.
• Community Templates: Updated error messages to reflect local static asset source instead of GitHub API references.

Maintenance (2026-04-18 Hardening Batch)

• CI / Codecov: Replaced deprecated pnpm dlx codecov upload flow with codecov/codecov-action@v5 in .github/workflows/ci.yml.
• CI / Failure Visibility: Removed continue-on-error from the Storybook job so broken Storybook builds fail CI as expected.
• CI / Lighthouse Behavior: Kept Lighthouse job soft-fail semantics for budget misses while using lhci autorun --assert.exitCode=0 to avoid false-red budget exits and still surface runtime crashes.
• Security Process: Added .github/SECURITY.md with supported versions table, private disclosure channels, and a default 90-day coordinated disclosure policy.
• PWA Update UX: Switched Service Worker update activation to explicit user consent. SKIP_WAITING is now sent only from the update toast action instead of auto-activation paths.
• Service Worker Lifecycle: Removed install-time self.skipWaiting() from public/sw.js to prevent forced activation during active writing sessions.
• Collaboration Resilience: Added wss://signaling.yjs.dev as a signaling fallback in services/collaborationService.ts to reduce single-point-of-failure risk.
• CSP Alignment: Extended connect-src in index.html for additional collaboration signaling endpoints (wss://signaling.yjs.dev, wss://*.workers.dev).
• Owner Documentation: Added collaboration failover and self-hosted signaling guidance (Cloudflare Worker path) to README.md.
• Test Hardening: Replaced the stub settingsSlice unit test with a comprehensive suite (29 tests, 331 LOC) covering all reducer actions and edge cases.
• Theme Roundtrip Testability: Exported applyInitialTheme from features/settings/settingsSlice.ts and added persisted-state roundtrip tests for localStorage + system-theme resolution.

Fixed

• Render-Blocking Fonts: Replaced 3 render-blocking @import url("https://fonts.googleapis.com/...") in index.css with self-hosted @fontsource/inter, @fontsource/jetbrains-mono, @fontsource/merriweather (woff2). Fonts are now bundled by Vite, eliminating external network requests and improving First Contentful Paint.

Security

• CSP Tightening (Fonts): Removed https://fonts.googleapis.com from style-src and connect-src, removed https://fonts.gstatic.com from font-src and connect-src in both index.html and src-tauri/tauri.conf.json. Fonts are now served from 'self' only.

Changed

• Service Worker: Removed Google Fonts Cache-First fetch handler and CACHE_FONTS cache bucket from public/sw.js (no longer needed with self-hosted fonts).
• Documentation Consolidation: Merged audit15april2026.md into AUDIT.md as a collapsible baseline section. Moved completed tasks from TODO.md to docs/history/completed-v1.1.md. Cleaned up TODO.md (current sprint only) and ROADMAP.md (quarterly+) with cross-references.

Removed

• audit15april2026.md (consolidated into AUDIT.md).
• Preconnect links to fonts.googleapis.com and fonts.gstatic.com from index.html.

Added

• @fontsource/inter, @fontsource/jetbrains-mono, @fontsource/merriweather as dependencies for self-hosted font loading.
• docs/history/completed-v1.1.md archive for completed v1.1 sprint tasks.

Fixed

• Logger No-ops: Fixed empty debug() and info() method bodies in logger.ts that silently discarded all debug/info log messages.
• Community Templates CSP: Replaced GitHub raw URL fetch in communityTemplateService.ts with local static asset (public/community-templates/index.json), eliminating CSP connect-src violations and enabling offline support.
• Ollama Browser Guard: Added window.__TAURI__ check in aiProviderService.ts to prevent Ollama connection attempts in the browser (CSP blocks localhost in the deployed PWA). Added amber warning banner in SettingsView for non-desktop environments.
• Tauri Ollama CSP: Changed Tauri CSP connect-src from broad http://localhost to explicit http://localhost:11434 http://127.0.0.1:11434 for Ollama API access.
• Service Worker Double-Track: Switched VitePWA from generateSW to injectManifest strategy, preventing conflicts with the custom public/sw.js service worker. Added self.__WB_MANIFEST injection point for precache manifest.
• i18n Eager Loading: Replaced 70 parallel fetch calls (14 modules × 5 languages) at boot with lazy single-bundle loading (2 fetches max: active language + EN fallback). Added scripts/build-i18n.mjs prebuild step to merge per-module JSON files into public/locales/<lang>/bundle.json.
• modulePreload Optimization: Converted all 14 AI thunks in projectSlice.ts from static imports to dynamic import() calls for aiProviderService and geminiService, keeping @google/genai out of the eager chunk graph. Added Vite modulePreload.resolveDependencies filter to skip preloading vendor chunks (ai-vendor, export-vendor, data-vendor, collaboration-vendor, canvas-vendor).

Security

• Tauri FS Scope: Replaced unscoped fs:allow-* permissions in src-tauri/capabilities/default.json with $APPDATA/**-scoped entries, preventing filesystem access outside the application data directory.

Added

• settings.ai.ollamaBrowserNote translation key in all 5 locale files (de, en, es, fr, it).
• public/community-templates/index.json static asset for offline community template loading.
• scripts/build-i18n.mjs build script for i18n bundle generation.
• prebuild npm script hook to auto-generate i18n bundles before production builds.

Fixed

• Critical: Configured Tailwind CDN dark mode to use selector strategy with .dark-theme class. Previously, all dark: prefixed Tailwind classes responded to OS system preference instead of the in-app theme toggle, causing broken styling when OS and app theme diverged.
