Attribution follows current practice on `main` (maintainer commits carry a `Co-authored-by: Claude …` trailer) and the brief this session was started with. + +--- + +## User Story 2 — Seed corpus + eval gate (P2) + +**Goal** +- The embedded bundle carries at least 25 gating signatures across at least 8 classes. Each signature has provenance, a redistributable licence and an eval pair. +- The bundle is built deterministically in-repo from per-signature sources. +- `scan-eval --gate` scores it through the production loader, and a deterministic negative control proves the gate is not vacuous (SC-004, SC-005 CI half, FR-001a, FR-012 to FR-016b). + +**Independent test** +- `go run ./cmd/tpa-corpus verify` exits 0. +- `go run ./cmd/scan-eval --corpus specs/065-evaluation-foundation/datasets/detect_corpus_v1.json --gate --min-recall 0.90 --max-fp 0.05` passes, with `tpa.bundle` in `checks`. +- `go test ./cmd/scan-eval/ -run TestBundleControl` shows that removing the control signature exits `6`. + +### Decisions (US2) + +**D-US2-1 — How rules are addressed.** +- `rules[].id` stays equal to the owning `TPA-YYYY-NNNN` id. Each `signatures[].rule_ids` entry is the string `"/"`. +- The loader enforces all of the following: + - `(id, detector)` is unique. + - Every `rule_ids` entry resolves. + - The id part of every `rule_ids` entry equals the owning signature's `id`. + - Every `rules[]` entry is owned by exactly one signature. +- *Rationale:* the CheckID `tpa..` is left unchanged. The CLI HELD column (`cmd/mcpproxy/tools_cmd.go:557`), the Web UI parser (`frontend/src/utils/holdEvidence.ts:71`) and the runtime prefix tests all depend on that shape. `/` is already the loader's error format (`tpa_bundle.go`, `compile rule %s/%s`). The contract example `r-hidden-important-block` would have broken all of them. + +**D-US2-2 — How "gating" is derived.** +- A rule is gating if and only if it is **runnable**, meaning `engine=="regex"` and `target=="tool_description"`. +- A signature must declare `gating: true` exactly when it owns at least one runnable rule. A mismatch in either direction rejects the bundle. +- A gating signature may also own non-runnable companion rules, such as the `structural_diff` rules of 0001 and 0006. +- `level` remains a severity label only. +- *Rationale:* `BundleCheck.Inspect` hard-codes `detect.TierHard` for every runnable rule (`tpa_bundle.go:170`). Deriving gating from `level`, as contract §4 rule 2 says, would therefore mean nothing. Out of Scope forbids tier changes, so the derivation has to follow what the loader really does. Today's 0002 (`resource_content` only) becomes the one non-gating signature. + +**D-US2-3 — Where integrity checks live (one implementation, two layers).** +- **Load layer.** File: `internal/security/scanner/tpa_bundle_signatures.go`. + - `validateSignatures` is called from `loadBundleCheck` after the zero-runnable check. A failure rejects the **whole** candidate, as FR-001a requires. `ConfigureBundle` then keeps the last-known-good bundle and records `LoadError`. + - It runs only when `signatures[]` is present, so v0.1 drops and every existing fixture keep loading (additive). + - It enforces: + - id grammar and uniqueness; + - D-US2-1 and D-US2-2; + - `rules[]` sorted by `(id, detector)`; + - `signature_count == len(signatures)`; + - non-empty `provenance.source`, `provenance.published` (format `YYYY-MM-DD`) and `license`; + - every `skipped[].id` resolves to a signature. +- **Policy layer, build and CI only.** File: `internal/security/tpacorpus/policy.go`. It enforces: + - the licence allowlist; + - the class vocabulary; + - the eval pair (contract rule 5); + - category registration (rule 6, closed by a scan-eval test). +- *Rationale:* rule 6 depends on `categoryCheck`, which lives in `package main`. Enforcing the SPDX allowlist at runtime would also refuse FR-004a operators who build private corpora. +- **Shared seam.** File: `internal/security/scanner/tpa_bundle_eval.go`. It exports `LoadBundleCheck(data []byte) (*BundleCheck, BundleInfo, error)`, which is pure and touches no `ConfigureBundle` state, plus `EmbeddedBundle() []byte` and `ParseBundleSignatures(data) ([]Signature, error)`. + - The builder, `scan-eval --bundle` and (US1/087) the activation self-check all call it. + - It goes in a new file so it does not collide with US1's edits to `tpa_bundle_source.go`. + +**D-US2-4 — Sources and the deterministic build.** +- **Sources.** One JSON file per signature in `internal/security/tpacorpus/signatures/TPA-YYYY-NNNN.json`. Each file holds the signature metadata, its rules and its skipped entries. +- **Manifest.** `internal/security/tpacorpus/signatures/manifest.json` holds: + - `bundle_version`; + - `schema_version`; + - `source_date_epoch`; + - a `header` object of extra top-level keys copied through verbatim. US1 puts `sequence`, `trust_epoch` and similar keys there without touching the builder. +- **Builder.** The library is `internal/security/tpacorpus`. The CLI is `cmd/tpa-corpus`, with the subcommands `build`, `verify` (rebuild and byte-compare) and `validate --bundle --dataset`. + - It sorts `rules[]` by `(id, detector)` and `signatures[]` by id. + - `generated_at` comes from `SOURCE_DATE_EPOCH` when that is set, and otherwise from the manifest pin. Wall-clock time is never used (FR-002). + - It encodes with stdlib `encoding/json`, `SetIndent("", " ")`, `SetEscapeHTML(false)` and a trailing LF. This matches today's file byte-for-byte. + - It adds no new dependencies and does not sign; signing is US1's job. +- *Rationale:* `cmd/tpa-db` (keygen and sign) belongs to US1, so a separate command avoids a `main.go` conflict. `verify` in CI makes a hand-edited `scanner-bundle.json` fail. The `spec.md` Assumption that "the pipeline is outside the repo" is amended in T206. + +**D-US2-5 — Class vocabulary.** +- `signatures[].category` is a snake_case slug with the prefix `tpa_`. Each class gets a **static** entry `categoryCheck["tpa_"] = "tpa.bundle"`. +- The prefix avoids collisions with the built-in categories `shadowing` and `phrase_injection`. +- The vocabulary lives once, in `tpacorpus.Classes`. The scan-eval test and the dataset validator both assert against it. +- Proposed classes (T207 finalises them; there must be at least 8, each with at least one gating signature): + - `tpa_hidden_instruction_block` + - `tpa_comment_directive` + - `tpa_tool_shadowing` + - `tpa_cross_server_override` + - `tpa_exfil_redirect` + - `tpa_sensitive_file_coaxing` + - `tpa_rug_pull_phrasing` + - `tpa_concealment_directive` + - `tpa_agent_config_persistence` (the control) + - `tpa_markdown_image_beacon` +- `rules[].category` keeps its v0.1 meaning, which is the threat-type mapping. `bundleCategoryToThreatType` gains one case, `"exfiltration"` → `detect.ThreatExfiltration`, so exfil classes do not fall into `uncategorized`. +- No class name may be a prefix of another class name. + +**D-US2-6 — Where eval samples go.** +- The samples extend `specs/065-evaluation-foundation/datasets/detect_corpus_v1.json` **in place**. +- *Rationale:* this follows the Spec 077 T016 precedent. No test pins the file's hash or count, and the edit keeps `eval.yml`, `release-qa-gate.yml`, `gate_test.go:240`, `coverage_corpus_test.go:13`, the docs and the spec's own Independent Test valid without repointing them. The README's immutability note is amended to say so. +- Bundle-class malicious entries gain an optional `tpa_id` field. Exactly one entry per class also carries `"canonical": true`. Unknown keys are ignored by every decoder. +- Hard negatives use the id prefix `hn__`, for example `hn_tpa_exfil_redirect_01`, with `resembles: ""`. `hardNegPrefix` is derived from `tpacorpus.Classes`. FR-013 and AC-4 are reworded to "the prefix the validator registers for the category". +- New hard negatives must stay at **zero** hard findings under the production engine, not merely 5%. `TestCoverage_BenignNotHardBlocked` (`coverage_corpus_test.go:126`) hard-fails on any benign entry the bundle blocks. + +**D-US2-7 — The D9 control.** +- The control signature is the new `tpa_agent_config_persistence` signature. Its sample is an instruction to append to `CLAUDE.md`/`.cursor/rules`. + - It contains no override phrase, exfil verb, secret noun, URL, credential file, hidden rune or blob. + - It matches none of the existing rules. +- The control corpus is `cmd/scan-eval/testdata/bundle_control_corpus.json`. It contains: + - 1 malicious entry (`tpa_id` = control, `peers: []`, plain schema, ASCII only); + - at least 1 `hn_tpa_agent_config_persistence_*` hard negative; + - 1 benign entry. + - With this corpus, `GatedMalicious == 1`: recall is 1.0 with the control signature and 0.0 without it. The run exits `6`, never `4`. +- The reduced bundle is built by `tpacorpus.Build(..., Options{Exclude: []string{controlID}})`. That drops the signature and its rules and recomputes `signature_count`, so the reduced bundle still passes the load layer. +- No-overlap is asserted twice: + - against the gate built-ins (`builtinGateChecks()`); + - against the production `baselineEngineChecks()`. With the full bundle, the only `tpa.` signal must be `tpa..*`. +- Identical patterns cannot serve as a control. `0004.shadow_directive` and `0005.cross_shadow` share one regex, and `0001` co-fires `0003`. + +**D-US2-8 — `eval.yml`.** +- The gate command stays as it is, because `--bundle` defaults to the embedded bundle and the existing step now scores it. +- Add the path filter `cmd/tpa-corpus/**`. +- Add a blocking step that runs `go run ./cmd/tpa-corpus verify` and `go test -count=1 -run 'TestBundleControl|TestCategoryCheck|TestSC004|TestEmbeddedCorpus' ./cmd/scan-eval/ ./internal/security/scanner/ ./internal/security/tpacorpus/`. +- Update the job comments. `release-qa-gate.yml` needs no edit, because it inherits the embedded default. + +**D-US2-9 — SC-004 test.** +- File: `internal/security/scanner/tpa_corpus_sc004_test.go`. +- It checks the embedded bundle has at least 25 **gating** signatures and at least 8 classes, each class with at least 1 gating signature. A non-gating signature such as 0002 cannot pad the count. +- It checks that every signature has provenance and a licence on the allowlist. +- For each class, it loads the `canonical: true` dataset entry and runs `inProcessToolScan`, which is the production path. It asserts a hard finding whose `Signals` contain the prefix `tpa..`. A hard tier reached only through `phrase.injection` does not count. + +**D-US2-10 — Hunks that conflict with US1** (rebase onto whichever side lands first) +- **`tpa_bundle.go`:** + - `rawBundle`: add the field `Signatures` (US1 adds manifest fields). + - The tail of `loadBundleCheck`: one `validateSignatures` call just before `return` (US1 inserts ceilings and the epoch check between parse and version check). + - `bundleCategoryToThreatType`: one new case. + - US2 does **not** touch `bundleMeta`/`bundleMetadata`. +- **`scanner-bundle.json`:** the whole file is regenerated. If US1 lands header keys first, port them into the manifest `header`, then run `build`. +- **`tpa_bundle_test.go` / `tpa_bundle_source_test.go`:** both stories edit the pinned assertions. +- **`tpa_bundle_source.go` and `inprocess.go` (`coverageOK`):** US2 makes **no** edits. + +**Licence allowlist (policy layer):** `CC0-1.0`, `CC-BY-4.0`, `MIT`, `Apache-2.0`. +- `CC-BY-SA-4.0` is dropped, because its share-alike terms could attach to the MIT-licensed binary that embeds it. The maintainer can re-add it in the contract. +- Patterns written by the project are `MIT` (the repo `LICENSE`). +- `provenance.source` is the factual public disclosure. Its licence is not the signature's licence. +- Dataset `provenance.license` stays on its own allowlist, where `self-authored` remains valid. + +**Version:** the embedded bundle moves to `bundle_version` `0.1.1`. This is a patch bump for the additive `signatures[]`, so the loader's `0.1` gate still accepts it. + +### Foundations + +- [ ] T200 [P] Write a failing table test in `internal/security/scanner/tpa_bundle_signatures_test.go`. + - **Reject cases.** One case per rule in D-US2-1, D-US2-2 and D-US2-3. Each asserts its own error substring. + - **Fail-closed through `ConfigureBundle`.** The last-known-good bundle keeps serving and `LoadError` is set. + - **Accept cases.** + - A valid bundle with `signatures[]` loads. + - A v0.1 bundle without `signatures[]` loads unchanged.

Do not use root or blog-index URLs, and do not invent URLs; unverifiable sources are dropped. + - The licence for each signature. + - The control designation (D-US2-7). + - A pre-check of every planned regex against the hard families in `phrase_injection.go`. The aim is to label each signature as built-in-overlapped or bundle-only, not to avoid overlap except for the control. + - The note that IoC-literal patterns (`attkr@pwnd.com`, `+13241234123`) are narrow, campaign-specific signatures.

From 6b8915283ed83e251b9fae36ada7f379cb7fc7ca Mon Sep 17 00:00:00 2001 From: Algis Dumbris Date: Tue, 20 Oct 2026 13:04:03 +0300 Subject: [PATCH 02/27] feat(scanner): validate bundle signatures[] and export a pure bundle loader Spec 101 US2 foundations (T200-T204). The loader now checks the optional signatures[] section for referential integrity (rule_ids resolve and are owned exactly once, gating matches runnable rules, sorted rules, signature_count, provenance, skipped ids) and rejects the whole bundle on any violation, so ConfigureBundle keeps the last-known-good corpus. v0.1 bundles without the section load unchanged. LoadBundleCheck, EmbeddedBundle and ParseBundleSignatures give the corpus builder and scan-eval a seam that never touches the active bundle. The "exfiltration" rule category now maps to detect.ThreatExfiltration.

Date: Tue, 20 Oct 2026 13:06:10 +0300 Subject: [PATCH 03/27] docs(spec-101): amend contracts and spec docs for the in-repo TPA corpus builder US2 settled several things the original contract left open: rule_ids use "/" to keep the CheckID shape the CLI and Web UI parse, gating is derived from runnable rules (the loader hard-codes the hard tier, so level carries no meaning), integrity checks split into a load layer and a build/CI policy layer, CC-BY-SA-4.0 leaves the licence allowlist, and signature_count is len(signatures). Each amendment is marked inline so reviewers can see what changed. The pipeline assumption becomes an in-repo deterministic builder (cmd/tpa-corpus) with signing left to US1.

The **load layer** (`internal/security/scanner/tpa_bundle_signatures.go`, `validateSignatures`, called from `loadBundleCheck`) runs in the binary at every load and activation, only when `signatures[]` is present so v0.1 bundles keep loading. It enforces: id grammar and uniqueness (rule 3); `rule_ids` resolution, the `(id, detector)` uniqueness and the id-part-equals-owner check (rule 1); the gating derivation (rule 2); `rules[]` sorted by `(id, detector)`; `signature_count == len(signatures)`; non-empty `provenance.source`, `provenance.published` in `YYYY-MM-DD` form and `license`; and every `skipped[].id` resolving to a signature. The **policy layer** (`internal/security/tpacorpus/policy.go`) runs at build and in CI only. It enforces: the licence allowlist (rule 4), the class vocabulary, the eval pair (rule 5), and category registration (rule 6, closed by a scan-eval test, because `categoryCheck` lives in `package main`).

A rule is gating if and only if `engine=="regex"` and `target=="tool_description"`. `BundleCheck.Inspect` hard-codes the hard tier for every runnable rule, so `level` is a severity label only and deriving from it would mean nothing. A signature declares `gating: true` exactly when it owns at least one runnable rule, and a mismatch in either direction rejects the bundle. A gating signature may also own non-runnable companion rules, such as `structural_diff` rules. A signature owning only non-runnable rules, such as a `resource_content` one, is the non-gating case. The paragraph below is kept for the reasoning, with "derive it from `level`" read as "derive it from runnable".) + **"Gating" must be mechanical, because `rules[]` has no such field.** Its keys are `category, confidence, detector, engine, flags, id, indicators, level, pattern, severity, target, type` — nothing that says "this rule gates approvals". Left as prose about intent, the check is unenforceable and a hard-tier rule can evade attribution entirely, or be attached to a `gating: false` signature and thereby dodge the FR-013 eval-evidence requirement while still driving the approval gate at runtime. The build MUST therefore derive it from `level` — a rule is gating **iff** it emits at the hard tier, which is exactly what FR-014 says gating means and exactly what the eval gate and the `scan`-mode approval gates score — and MUST reject any bundle where a hard-tier rule's owning signature has `gating: false`. `signatures[].gating` is then a declaration that is *checked* against the rules it names, not an independent switch; 3. `id` values are unique; 4. `license` is in the allowlist; -5. every `gating: true` signature has its FR-013 eval pair in the frozen dataset — ≥1 labeled gated-malicious sample and ≥1 category-matched hard negative following the `hn__*` naming the dataset validator enforces; +5. every `gating: true` signature has its FR-013 eval pair in the frozen dataset — ≥1 labeled gated-malicious sample and ≥1 category-matched hard negative following the hard-negative id prefix the dataset validator registers for the category (amended by US2, 2026-10-20: `hn__`, for example `hn_tpa_exfil_redirect_01` with `resembles: ""`; the prefix is derived from `tpacorpus.Classes`).

A bundle naming a category the gate cannot enforce is rejected at build, not merely noted. Direction 2 is the one a naive implementation drops, and it is the one that matters: checking only "signatures point at real rules" lets a gating rule ship with no campaign record at all, which is the state the corpus is in today.

Add internal/security/tpacorpus, which compiles one source file per signature plus a manifest into the bundle byte-for-byte reproducibly (sorted rules and signatures, alphabetical keys, generated_at from a pinned epoch, never the wall clock), refuses sources without provenance, with a licence outside the allowlist or with an unknown class, and checks its own output through the production loader. ValidatePolicy checks the eval pair every gating signature owes. The new cmd/tpa-corpus exposes build, verify (byte-compare, non-zero on drift) and validate. Migrate the six existing signatures into sources with their rules and skipped entries unchanged, add the signatures[] section (0002 is the one non-gating signature) and move the bundle to 0.1.1.

96e4a31591a0150e1dc1ca9e53e92a4266a13a89 Mon Sep 17 00:00:00 2001 From: Algis Dumbris Date: Tue, 20 Oct 2026 13:06:31 +0300 Subject: [PATCH 05/27] feat(scan-eval): score the TPA signature bundle in the detect gate The gate only ran the four built-in checks, so a change to the bundle corpus could never move recall/FP. Add --bundle (empty = embedded) and run BundleCheck alongside the built-ins, mirroring the production hard surface. A missing or invalid candidate bundle exits 4 and never falls back to the embedded default. The metrics gain a bundle block (fingerprint, version, runnable rules, signature count).

From 1cf931ec8063cb2f58793566d476c1c207ed8482 Mon Sep 17 00:00:00 2001 From: Algis Dumbris Date: Tue, 20 Oct 2026 13:52:47 +0300 Subject: [PATCH 07/27] feat(security): 44-signature TPA corpus across 16 classes, bundle v0.1.1 The seed corpus was six signatures in a handful of classes, too thin to claim coverage of the published tool-poisoning techniques. Add TPA-2026-0007..0044, each a self-authored MIT regex (RE2, bounded gaps, anchored on the technique's distinctive conjunction) with provenance pointing at the verified source, so every class in tpacorpus.Classes has at least one gating signature. 0002 and 0010 target resource content, which cannot run offline, so they stay non-gating; 0044 is the deterministic negative control for the gate. The concealment rule (0035) matched a security scanner's own description ("conceal its actions from the user"), so its keep/hide/ conceal clause now requires an imperative object (this, it, the step...) instead of any phrase ending in "from the user". 0002 and 0006 cited sources that do not contain their techniques and now cite the ones that do. Rebuilt with the manifest pin: 44 signatures, 85 runnable rules (was 7), 4 not-runnable rules (was 3); TestLoadEmbeddedBundle pins the new counts.

Tue, 20 Oct 2026 13:53:02 +0300 Subject: [PATCH 08/27] test(scan-eval): eval pairs for every TPA signature, validated against the bundle A gating signature with no labeled sample is unmeasured: the gate could not tell a regression in it from silence, and nothing proved its regex spares the benign look-alikes. Extend detect_corpus_v1.json in place (the 57 earlier entries are byte-identical) with one malicious sample per gating signature and two attack-resembling hard negatives per signature, security tooling and docs that quote the attack, plus one canonical sample per class for the SC-004 test. The validator derives the tpa_* categories and the hn__ prefixes from tpacorpus.Classes, checks the optional tpa_id/canonical keys, and guards that no hard-negative prefix nests inside another (an id could otherwise satisfy two categories). tpa_id is kept off hard negatives because ValidatePolicy rejects a non-malicious entry that names a signature. The embedded bundle is now checked against the dataset by policy in-process, the twin of `tpa-corpus validate`. README composition is recounted (it said 32; the file had 57, now 182).

Map each class in tpacorpus.Classes to tpa.bundle with static entries (a class is a reviewed change), and add TestCategoryCheck_CoversCorpusClasses so the vocabulary and the map cannot drift apart: it covers every class and every gating signature category in the embedded bundle. Gate on the extended corpus: overall recall 1.0 over 71 gated malicious entries, 0 false positives over 104 hard negatives, every tpa_* category gated.

Add a deterministic negative control: TPA-2026-0044, whose sample no built-in hard check flags. Its own corpus scores recall 1.0 with the full bundle and 0.0 with the signature excluded, and the second run must exit 6 (recall breach), not 4 (load error). Also add the SC-004 breadth test (>=25 gating signatures, >=8 classes, every class covered, provenance and licence on every signature, each class's canonical sample hard-flagged by its own tpa. signal through the production scan path), and run verify, validate and these tests as a blocking step in the security-d2 eval job.

Do not confuse the two. +- `id` is `TPA-YYYY-NNNN`, unique across the corpus. Every `rules[].id` equals + the owning signature's `id`. +- `detector` is a short snake_case name, unique within the signature. The pair + `(id, detector)` is the rule's address. The bundle lists it as the string + `"/"` in `signatures[].rule_ids`, and findings report the + check id `tpa..`. +- `pattern` is an RE2 regex, written inline as `(?is)...` or `(?s)...`. No + lookarounds and no backreferences. +- `confidence` is 0.80 to 0.95. `level` is `high` or `critical` and is a + severity label only; it does not change the tier. +- `skipped[]` records rules that exist upstream but cannot run offline (for + example an LLM-judge detector). Each `skipped[].id` must resolve to a + signature. +- The builder sorts rules by `(id, detector)` and signatures by id, so the order + in your source does not matter. + +### Gating + +A rule is **runnable** when its `engine` is `regex` and its `target` is +`tool_description`. A signature declares `"gating": true` exactly when it owns at +least one runnable rule, and `false` otherwise; a mismatch in either direction +rejects the whole bundle at load time. A gating signature may also own +non-runnable companion rules (for example a `structural_diff` rule). + +All runnable rules are **hard tier**: a match auto-quarantines the tool. That is +why patterns must be narrow, and why every gating signature owes a +hard-negative sample (below). A non-gating signature (today `TPA-2026-0002` and +`TPA-2026-0010`, whose rules target `resource_content`) documents an attack the +offline scanner cannot see; it contributes nothing to the gate. + +## Authoring a signature + +1. Pick the next free `TPA-YYYY-NNNN` id and the class that best names the + technique. Add the source file under `signatures/`. +2. Write the regex around the technique's **distinctive conjunction**, for + example a directive verb plus a sensitive object inside a bounded window + (`.{0,80}`), not a single common word. Prefer bounded lazy quantifiers + (`.{0,200}?`) over an unbounded `.*?` across the whole description. +3. Remember what benign tools say. A security scanner whose description + *mentions* `~/.ssh` or "credentials", and the descriptions of popular tools + (filesystem, git, browser, email, Slack), must not match. If a regex trips a + benign sample, narrow the regex; never loosen a test or a baseline. +4. Fill in provenance and licence (next section). +5. Add the eval samples (see "Eval samples"). +6. Run the loop in "Build and verify". + +## Provenance and licence rules + +- `provenance.source` must be a **verifiable public disclosure URL** for the + technique, and `provenance.published` its date (`YYYY-MM-DD`). Never invent + either. A blog index, a site root or any other URL that does not point at the + disclosure itself is refused. `provenance.note` is one short sentence of + human context. +- `license` must be on the allowlist `tpacorpus.LicenceAllowlist`: `CC0-1.0`, + `CC-BY-4.0`, `MIT`, `Apache-2.0`. +- **`CC-BY-SA-4.0` is deliberately excluded.** Its share-alike terms could + attach to the MIT-licensed binary that embeds the corpus. +- Signatures whose regex and sample text you wrote yourself are `MIT`. That is + the normal case: you reconstruct the technique in your own words. +- **Never copy sample text** from a source whose licence is not on the + allowlist, and prefer your own wording even when it is. The source URL records + where the technique was disclosed; it is not a licence to copy its text. +- Samples may use only `*.example.invalid` hosts and `example.invalid` e-mail + domains, no real secrets, keys or tokens, and no working commands against real + infrastructure. + +The licence and class checks run at build and in CI (`tpacorpus.ValidatePolicy`), +not when the binary loads a bundle, so operators can still load private corpora +with other licences. + +## Eval samples + +Samples live in `specs/065-evaluation-foundation/datasets/detect_corpus_v1.json` +and carry `"provenance": {"source": "self-authored", "license": "self-authored"}`. +For a gating signature the validator requires: + +- at least one **malicious** entry with `tpa_id` set to the signature id and + `category` equal to the signature's class; +- exactly **one canonical** malicious entry per class (`"canonical": true`), + which the SC-004 test runs through the production scan path. It must produce + a hard finding carrying a signal that starts with `tpa..` (a hard + tier reached only through `phrase.injection` does not count); +- at least one **hard negative** per class: a benign entry whose id starts with + `hn__` and whose `resembles` is that class (for example + `hn_tpa_exfil_redirect_01`). A good hard negative is a realistic benign tool + that talks about the same subject; +- **zero hard findings** on hard negatives under the production engine, not + merely under the 5% gate threshold (`TestCoverage_BenignNotHardBlocked`); +- `example.invalid` hosts only. + +## Adding a new class + +A new class is rare and a reviewed change. Register it in four places, or a +test fails: + +1. `tpacorpus.Classes` in `internal/security/tpacorpus/classes.go`. +2. `categoryCheck` in `cmd/scan-eval/gate.go`: `"tpa_": "tpa.bundle"`. + The entry is static on purpose. +3. The dataset validator, which derives the accepted categories, the gated + categories and the hard-negative prefixes from `tpacorpus.Classes`. Nothing + to edit once step 1 is done, but its tests must stay green. +4. The dataset entries: a canonical malicious sample and `hn__*` hard + negatives. + +## Build and verify + +```bash +# Rebuild the embedded bundle from signatures/ (deterministic; no wall-clock time) +go run ./cmd/tpa-corpus build + +# CI check: rebuild in memory and byte-compare with the committed bundle +go run ./cmd/tpa-corpus verify + +# Policy (licence, class, eval pairs) plus the production loader, against the dataset +go run ./cmd/tpa-corpus validate \ + --bundle internal/security/scanner/bundled/scanner-bundle.json \ + --dataset specs/065-evaluation-foundation/datasets/detect_corpus_v1.json + +# Score the corpus (the embedded bundle by default) +go run ./cmd/scan-eval \ + --corpus specs/065-evaluation-foundation/datasets/detect_corpus_v1.json \ + --gate --min-recall 0.90 --max-fp 0.05 + +# Score a candidate bundle instead +go run ./cmd/scan-eval \ + --corpus specs/065-evaluation-foundation/datasets/detect_corpus_v1.json \ + --gate --min-recall 0.90 --max-fp 0.05 --bundle path/to/candidate-bundle.json +``` + +The build is reproducible: `generated_at` comes from `SOURCE_DATE_EPOCH` when +set and from the manifest pin otherwise, output is sorted, and encoding is +stable. Before pushing, also run +`go test ./internal/security/tpacorpus/ ./internal/security/scanner/ ./cmd/scan-eval/`. + +## How the gate blocks a bad corpus + +`scan-eval --gate` loads the bundle through the **production loader**, adds the +resulting `tpa.bundle` check to the four built-in hard checks, and scores the +dataset. A load error is reported as an error; the gate never falls back to the +embedded corpus when you asked for another one. + +- **Thresholds.** Recall must be at least 0.90 over gated malicious samples and + the false-positive rate at most 0.05 over hard negatives. A breach prints + `GATE FAILED: ...` and exits `6`. +- **Unmapped categories are a hazard.** The gate only enforces a category whose + check is registered, and a category with no `categoryCheck` entry is measured + but never fails the build. For a corpus that grows by class that is a silent + hole: a class with no mapping would be reported yet could never fail CI. + `TestCategoryCheck_CoversCorpusClasses` closes it: every entry of + `tpacorpus.Classes`, and the category of every gating signature in the + embedded bundle, must map to `tpa.bundle`. +- **The negative control.** Aggregate recall alone would be vacuous: with 42 + gating signatures, deleting one would still leave recall above 0.90. So one + signature, `TPA-2026-0044` (class `tpa_persistence_implant`, an instruction + to write into an agent config file), is a deterministic control. Its sample + contains no override phrase, exfiltration verb, secret noun, URL, credential + file, hidden character or blob, and matches no other rule. A small dedicated + control corpus (`cmd/scan-eval/testdata/bundle_control_corpus.json`) has + exactly one gated malicious sample, so recall is 1.0 with the control + signature and 0.0 without it. The control test (`TestBundleControl*` in + `cmd/scan-eval`) builds a reduced bundle with the control excluded, and the + gate must exit `6`. If a gate change ever lets that pass, the gate has + stopped measuring the bundle. +- **No-overlap.** The control only proves anything if nothing else catches its + sample. The tests assert that neither the gate built-ins nor the production + engine's baseline checks produce a signal for it, so with the full bundle the + only `tpa.` signal is `tpa.TPA-2026-0044.*`. For the same reason, never give + two signatures identical patterns. +- **SC-004 floor.** A test over the embedded bundle requires at least 25 + gating signatures across at least 8 classes with at least one gating + signature each, provenance and an allowlisted licence on every signature, + and the per-class canonical check above. Non-gating signatures cannot pad the + count. + +## Benign real-world corpora + +A new hard-tier regex runs against every tool a user has, so it is also tested +against real benign tool definitions the repository vendors: the 527-tool +LiveMCPTool snapshot (70 servers, including non-English descriptions) and the +45-tool reference-server corpus. Run this before committing any regex: + +```bash +go test ./internal/security/scanner/ \ + -run 'TestSEC01_RealWorldBenignCorpora_NoNewHolds|TestSEC01_VariantCorpus|TestCoverage_BenignNotHardBlocked' +``` + +`TestSEC01_RealWorldBenignCorpora_NoNewHolds` compares every tool, one by one, +against `internal/security/scanner/testdata/sec01_realworld_baseline.json`.

Proactive sweep: every runnable rule of TPA-2026-0007..0044 (all 85 rules in the bundle bar the pinned v0.1 0001-0006) was probed with benign descriptions and narrowed where it matched; 564 new hard negatives are added to detect_corpus_v1.json (appended; existing entries byte-identical). Hard negatives that the built-in unicode.hidden / phrase.injection / payload.decoded checks hard-flag were reworded, and the ten raw bidi/ZWNJ/tag samples for 0036 were dropped (unicode.hidden flags those by design).

Dataset: +8 malicious own-words samples and +21 hard negatives (904 entries); bundle rebuilt (94 rules, 90 runnable); README counts and TestLoadEmbeddedBundle updated.

Eval corpus (detect_corpus_v1.json, append-only): +1 malicious (tpa_0033_m2) and +47 hard negatives (904 -> 952 entries); README composition updated. One 0022 hard negative reworded to avoid a built-in phrase.injection hard flag. Bundle rebuilt (98 rules, 94 runnable); TestLoadEmbeddedBundle count updated.

Eval corpus: +60 hard negatives (952 -> 1013 entries) and one malicious sample (tpa_0044_m3, backticked filenames). Three 0022 negatives were reworded so no built-in check hard-flags them. Gate: 82/82 gated malicious, recall 1.0, 924 hard negatives, fp 0.

Dataset: +21 malicious samples and +66 hard negatives appended; 10 new hard negatives reworded where a built-in check (phrase.injection) hard-flagged them (send -> share, ~/.ssh/config -> ~/.npmrc). Bundle rebuilt (95 runnable rules).

Dataset: +12 malicious samples and +49 hard negatives (detect_corpus_v1.json, appended in place; existing entries byte-identical). Gate: recall 1.00, FP 0.
