Release v3.8.35 (#4743)

* chore(release): open v3.8.35 development cycle

* fix db vacuum scheduler settings (#4726)

Scheduled VACUUM now follows Storage page settings (scheduledVacuum/vacuumHour) as single source of truth; env-flag control path removed. 11/11 vacuum-scheduler tests pass against release/v3.8.35 tip; no orphaned env refs. Integrated into release/v3.8.35.

* fix(tier): noAuth providers count as free; free filter returns empty … (#4753)

noAuth providers now classified free (union of legacy list + NOAUTH_PROVIDERS chat-tier derivation), -free arena_elo alias, and auto/<cat>:free returns an empty pool when no free candidate matches (opt-in legacy fallback via OMNIROUTE_AUTO_FREE_FALLBACK_TO_FULL_POOL). New env var documented in .env.example + ENVIRONMENT.md; CHANGELOG bullet added (maintainer co-author). 46/46 node + 56/56 vitest tests pass on release tip; env-doc-sync, docs-sync, typecheck:core, lint, file-size all green. Integrated into release/v3.8.35.

* refactor(chatCore): extrai 11 helpers de nível superior para 6 leaves puros (#3501) (#4571)

chatCore god-file decomposition (#3501): extract 6 pure leaves (cacheUsageMeta, executorClientHeaders, nonStreamingResponseBody, skillsFormat, streamErrorResult, streamFinalize) from chatCore.ts. Rebased onto release/v3.8.35 tip (resolved single chatCore.ts conflict — removed now-extracted inline buildExecutorClientHeaders). 265/265 chatcore tests, 26/26 new leaf tests, typecheck:core, cycles, file-size all green. Integrated into release/v3.8.35.

* refactor(chatCore): extrai resolveExecutorWithProxy + getExecutionCredentials para leaves (#3501) (#4646)

chatCore #3501: extract resolveExecutorWithProxy + getExecutionCredentials to leaves (executorProxy.ts, executionCredentials.ts). Clean cherry-pick onto release tip post-#4571. 12/12 new leaf tests, typecheck:core, cycles, file-size green. Integrated into release/v3.8.35.

* refactor(chatCore): extrai transforms de mensagens Claude p/ leaf (#3501) (#4708)

chatCore #3501: extract Claude upstream-message transforms to leaf (claudeUpstreamMessages.ts + claudeMessageTypes.ts). Clean cherry-pick post-#4646. 8/8 new leaf tests, typecheck/cycles/file-size green. Integrated into release/v3.8.35.

* refactor(chatCore): extrai persistAttemptLogs para leaf (#3501) (#4717)

chatCore #3501: extract persistAttemptLogs to leaf (attemptLogging.ts). Rebased onto release tip post-#4708 (resolved imports conflict: kept tip's resolveCompressionHeader from compression Phase 3, dropped now-unused logTruncation import moved into the leaf). 288/288 chatcore tests, typecheck/cycles/file-size green. Integrated into release/v3.8.35.

* refactor(chatCore): extrai stageTrace + compressionUsageReceipt para leaves (#3501) (#4721)

chatCore #3501: extract stageTrace + compressionUsageReceipt to leaves. Clean cherry-pick post-#4717. 6/6 new leaf tests, typecheck/cycles/file-size green. Integrated into release/v3.8.35.

* refactor(chatCore): extrai prepareUpstreamBody (1ª sub-fatia do executeProviderRequest, #3501) (#4730)

chatCore #3501: extract prepareUpstreamBody (first sub-slice of executeProviderRequest) to leaf (upstreamBody.ts). Clean cherry-pick post-#4721. 7/7 new leaf tests, full 301/301 chatcore suite, typecheck/cycles/file-size green. Completes the 6-PR chatCore decomposition stack into release/v3.8.35.

* fix(db): make db-backup import size cap configurable (#4719) (#4757)

Co-authored-by: Diego Rodrigues de Sa e Souza <souzamiriamrodrigues790@gmail.com>

* chore(quality): expand check:release-green to the FULL release-PR gate set (#4758)

The release-green pre-flight (Solution C) previously covered only a subset of the
gates that run exclusively on the release PR (PR→main), so reds still accrued
silently on release/** and surfaced in ~40-min layers at release time (v3.8.34:
3 CI rounds — CodeQL sanitization, then the fail-fast Quality Ratchet revealing
openapi then cyclomatic-complexity one push at a time, plus zizmor/integration).

Now check:release-green reproduces the COMPLETE release-PR gate set and reports
EVERY red in one pass (collected, not fail-fast):

- New DRIFT ratchets (report-only, rebaselined at release, never block):
  cyclomatic complexity, dead-code, type-coverage, compression-budget,
  openapi-coverage, workflow-lint (zizmor), codeql-ratchet.
- New HARD gates (real defects): docs-all (fabricated-docs strict + i18n mirror
  sync) and the integration test suite (gated behind !--quick).

The only release-PR gates it still cannot reproduce locally are GitHub-side CodeQL
semantic analysis and SonarQube/SonarCloud (external services).

The nightly-release-green workflow and /green-prs inherit the expanded coverage
automatically (they invoke this script), so cycle drift is now surfaced
continuously and the release PR is green on its first CI run.

* docs(compression): declare Phase 4 layers — Output Styles, adaptive dial, per-request control (#4801)

The README compression section listed the 9 input engines but not the Phase 4
layers now in production:
- Output Styles (output-axis steering: terse-prose / less-code / terse-cjk, lite/full/ultra)
- adaptive context-budget dial (reserve-output|percentage|absolute · floor|replace-autotrigger|off)
- per-request x-omniroute-compression precedence + the offline eval harness
Also bumped the highlights range to v3.8.35, expanded the compression feature bullet,
and marked the GUIDE's Phase 4 row Shipped (was 'Planned' — it's merged on v3.8.35).

* chore(release): finalize v3.8.35 CHANGELOG + docs reconciliation

- CHANGELOG: complete 3.8.35 section (all 35 commits since v3.8.34,
  contributor attribution: @rdself @megamen32 @KooshaPari @JxnLexn)
- docs(security): align THREAT_MODEL.md refs with real code
  (routeGuard.ts, tokenLimits.ts, /api/monitoring/health) — fabricated-docs gate
- check:fabricated-docs: skip docs/superpowers/specs (dated research reports)
- i18n: sync 3.8.35 section into 41 CHANGELOG mirrors (docs-sync size gate)
- ratchet rebaseline: cyclomatic 1916->1920, eslintWarnings 3907->3912
  (inherited cycle drift; release-finalize diff is docs-only)

* fix(release): resolve inherited base-reds surfaced by v3.8.35 release CI

Cycle base-reds that only run on PR→main (not the PR→release fast-path):

- test(autoCombo): suffixComposition-4517 used node:test in a vitest-only dir
  (#4753) → vitest found no suite. Switch to the vitest API. (Vitest job)
- test(agentSkills): openapiParser fixture wrote docs/reference/openapi.yaml;
  parser reads docs/openapi.yaml since #4781 → point fixture at the new path.
  (Unit/Coverage/Node24/Node26 shard 4)
- test(integration): proxy-pipeline source-scan expected inline streaming-cost
  code that #4790/#3501 extracted to the recordStreamingCost leaf → assert the
  delegation instead. (Integration 1/2)
- fix(chatCore): derive the log trace id from crypto, not Math.random
  (CodeQL js/insecure-randomness — log-correlation id, not a secret).
- test(resilience): circuit-breaker invalid-cooldown fallback asserted t>29000,
  flaking on slow CI where ~1.6s elapsed gave t=28401 → tolerate wall-clock
  drift (t>25000). (Unit 6/8)

* fix(usage): derive pending-request id from crypto, not Math.random

CodeQL js/insecure-randomness (#669): the pending-request id generated in
trackPendingRequest (usageHistory.ts) flows into attempt logging and was flagged
as insecure randomness in a security context. It's a log-correlation id, not a
secret — switch to crypto RNG to clear the alert. Pairs with the chatCore traceId
fix in 37c4978 (same sink).

+## [3.8.35] — 2026-06-23
+
+### ✨ New Features
+
+- **Adaptive context compression (Phase 4)**: a four-layer compression upgrade landed across stacked PRs — an **Output Styles** registry (`terse-prose` / `less-code` / `terse-cjk`) ([#4694](https://github.com/diegosouzapw/OmniRoute/pull/4694) — thanks @diegosouzapw), an opt-in **SLM `ultra` tier** (two-tier LLMLingua with heuristic fallback) ([#4707](https://github.com/diegosouzapw/OmniRoute/pull/4707) — thanks @diegosouzapw), a **context-budget adaptive dial** (reserve-output ladder + floor) ([#4716](https://github.com/diegosouzapw/OmniRoute/pull/4716) — thanks @diegosouzapw), and an **offline evaluation harness** (PII-gated corpus, self-test judge, gold-grader, real-pipeline runner behind a `ModelClient` seam) ([#4720](https://github.com/diegosouzapw/OmniRoute/pull/4720) — thanks @diegosouzapw). All four layers share a single `CompressionRunTelemetry` contract.
+- **Redoc-rendered API docs**: a consolidated OpenAPI spec now lives at `docs/openapi.yaml` and is served as interactive Redoc documentation at `/api/docs`. ([#4781](https://github.com/diegosouzapw/OmniRoute/pull/4781) — thanks @KooshaPari / @diegosouzapw)
+
+### 🔧 Bug Fixes
+
+- **db-backups**: make the database-import size cap configurable via `OMNIROUTE_DB_IMPORT_MAX_MB` (default 100 MB, 4 GB ceiling) so backups larger than 100 MB can be restored; error message now points to the env var and to VACUUM ([#4757](https://github.com/diegosouzapw/OmniRoute/pull/4757) — closes #4719, thanks @diegosouzapw).
+- **Onboarding**: add the missing `onboarding.tiers` step-title translation so the setup wizard no longer crashes with `MISSING_MESSAGE: onboarding.tiers` ([#4755](https://github.com/diegosouzapw/OmniRoute/pull/4755) — closes #4698, thanks @diegosouzapw).
+- **deepseek-web**: fold `role:"tool"` results into the single-prompt transcript (`messagesToPrompt`) so tool outputs reach the model instead of being silently dropped when a follow-up turn omits the `tools[]` array ([#4756](https://github.com/diegosouzapw/OmniRoute/pull/4756) — closes #4712, thanks @diegosouzapw).
+- **Dashboard**: remove the dead, unconditional `useLiveRequests()` call from `HomePageClient.tsx` — it crashed the `/home` page in production builds with `ReferenceError: useLiveRequests is not defined` (#4759, #4745) and opened the live-dashboard WebSocket even when Provider Topology was hidden (#4596). The live feed remains owned by the settings-gated `HomeProviderTopologySection` ([#4761](https://github.com/diegosouzapw/OmniRoute/pull/4761) — thanks @diegosouzapw).
+- **Providers dashboard**: dedupe provider nodes by id when adding a compatible provider (`upsertProviderNodeById`) so the same provider can no longer appear twice and no-op adds don't invalidate the compatible-provider memo ([#4768](https://github.com/diegosouzapw/OmniRoute/pull/4768) — closes #4746, thanks @diegosouzapw).
+- **Storage VACUUM**: the scheduled VACUUM job now follows the Storage page settings (`scheduledVacuum` / `vacuumHour`) as the single source of truth; the legacy env-flag control path was removed ([#4726](https://github.com/diegosouzapw/OmniRoute/pull/4726) — thanks @rdself).
+- **Tiers**: no-auth providers are now counted as free, and the free-tier filter returns an empty set instead of falling through to every provider ([#4753](https://github.com/diegosouzapw/OmniRoute/pull/4753) — thanks @megamen32 / @diegosouzapw).
+- **Combos**: auto-promote `zeroLatencyOptimizationsEnabled` so legacy configs (pre-3.8.33 `fallbackCompressionMode="lite"`) round-trip cleanly on the first GUI edit ([#4774](https://github.com/diegosouzapw/OmniRoute/pull/4774) — thanks @KooshaPari / @diegosouzapw).

 ### 🐛 Fixed
 
+- **fix(tier): noAuth providers count as free; `auto/<cat>:free` returns an empty pool when no free candidate matches** — `freeProviders` is now the union of the legacy explicit list and every chat-tier `noAuth` provider derived from `NOAUTH_PROVIDERS` (so opencode / mimocode / duckduckgo-web are correctly classified free), the task-fitness lookup inherits a base model's `arena_elo` for its `-free` variant, and the `auto/<category>:<tier>` filter no longer silently falls back to the full pool — a `:free` request that matches no connected free model returns empty instead of billing a paid model (opt back into the legacy fallback with `OMNIROUTE_AUTO_FREE_FALLBACK_TO_FULL_POOL=true`). Corrupted/invalid `tier_config` rows now log a structured warning and fall back to defaults instead of throwing. ([#4753](https://github.com/diegosouzapw/OmniRoute/pull/4753), [#4517](https://github.com/diegosouzapw/OmniRoute/issues/4517) — thanks @megamen32)
+- **fix(db): scheduled VACUUM follows Storage settings** — the SQLite VACUUM scheduler now uses the existing Storage page `scheduledVacuum` / `vacuumHour` configuration as its single source of truth, refreshes immediately when those settings are saved, and no longer exposes a separate environment-variable control path.
 - **fix(db): scheduled cleanup actually runs + queries target the real tables (DB-bloat / OOM)** — `runAutoCleanup` was never scheduled, so retention cleanup never executed and tables (`compression_analytics`, `usage_history`, …) grew unbounded into multi-GB SQLite files driving high RSS. Worse, several cleanup queries referenced wrong table/column names (`call_logs.created_at`→`timestamp`, `compression_analytics.created_at`→`timestamp`, `mcp_audit_log`→`mcp_tool_audit`, `a2a_events`→`a2a_task_events`, `memory_entries`→`memories`), so even a manual run silently no-op'd or errored. Fixed the five queries to match the real schema, added `cleanupProxyLogs`, and wired a `startCleanupScheduler` (startup + every 6h, VACUUM after deletes) into `server-init` alongside the existing budget-reset and reasoning-cache jobs.

 - **fix(routing): include all noAuth models in auto-combos + add reka-flash + best-free template** — noAuth provider models are no longer skipped when building auto-combos, `reka-flash` is registered, and a `best-free` combo template is added. ([#4621](https://github.com/diegosouzapw/OmniRoute/pull/4621) — thanks @oyi77)
 - **fix: noAuth provider validation + Kimi executor routing** — corrects noAuth provider membership checks and removes a mis-routed Kimi alias. (closes #4620) ([#4699](https://github.com/diegosouzapw/OmniRoute/pull/4699) — thanks @oyi77)

-- **fix(db): scheduled VACUUM + persist `lastVacuumAt`** — a new `vacuumScheduler.ts` persists the last run timestamp and last error to the `key_value` table (migration 102) and feeds the database settings panel; wired into the Next.js lifecycle (default 24h, window 02:00–04:00 local). New env flags: `OMNIROUTE_VACUUM_ENABLED`, `OMNIROUTE_VACUUM_INTERVAL_HOURS`, `OMNIROUTE_VACUUM_WINDOW`. ([#4480](https://github.com/diegosouzapw/OmniRoute/pull/4480) — thanks @KooshaPari / @oyi77)

 - **perf(quota): stop writing redundant `quota_snapshots` rows from idle connections** — the 60s background refresh persisted a snapshot for every window of every connection regardless of change, generating 400K+ rows/day from idle accounts. `setQuotaCache` now skips the write when a window's `remaining_percentage`/`is_exhausted` is unchanged from the last cached observation; the first observation and every real change still persist.
