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`. A +tool that moves from clean to warnings or dangerous, or loses scan coverage, +fails the test. **Never re-baseline that file** to make a signature pass; +narrow the regex instead. + +## Related

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`). "The frozen dataset" is read as "the dataset, extended in place": the samples are added to `specs/065-evaluation-foundation/datasets/detect_corpus_v1.json`; 6. every `gating: true` signature's `category` resolves to a **registered** `categoryCheck` entry in the gate. §5 below explains why an unmapped category is scored vacuously; that explanation is not enforcement, so this rule is what actually stops one shipping. 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. Rule 6 is the same failure one level up — a campaign record that exists but that the gate silently declines to score. @@ -88,3 +94,5 @@ Direction 2 is the one a naive implementation drops, and it is the one that matt - every `gating: true` signature has its eval pair (rule 5) Note `signature_count` (existing, top-level) counts **rules** and keeps that meaning.

The file shipped before US2 held 6 `signature_count` and 10 rules, so the two already differed. The load layer rejects a bundle where `signature_count != len(signatures)` when `signatures[]` is present; a v0.1 bundle without `signatures[]` keeps its old value untouched.

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. New classes use general phrasing. + - Source material: `tests/tpa-attack-lab/catalog.go` (V01–V19, M01–M06). RT-01..07 are mostly not description classes. Do not mine `docs/research/.../redteam-findings.md` for coverage claims, because it predates `a857dbafe`. +- [x] T208 [P] Write a failing test, `internal/security/tpacorpus/build_test.go`, using an `fstest.MapFS`. It must cover: + - two builds are byte-equal; + - `SOURCE_DATE_EPOCH` overrides the manifest pin, and `generated_at` is RFC 3339 UTC; + - `` is not escaped; + - `rules[]` and `signatures[]` come out sorted; + - the manifest `header` keys pass through; + - `Options.Exclude` drops the signature and its rules and fixes `signature_count`; + - the output passes `scanner.LoadBundleCheck`; + - the build refuses a source that is missing provenance or a licence, has a licence outside the allowlist, or has an unknown class. +- [x] T209 [P] Write a failing test, `internal/security/tpacorpus/policy_test.go`, for `ValidatePolicy(bundle, dataset []byte)`: + - each gating signature has at least 1 malicious entry with a matching `tpa_id` and category; + - each gating signature has at least 1 hard negative with `resembles == category` and prefix `hn__`; + - exactly one `canonical` entry per class; + - every `tpa_id` resolves; + - no class name is a prefix of another. +- [x] T210 Implement `internal/security/tpacorpus/` (`classes.go`: `Classes`, `LicenceAllowlist`; `build.go`: `Build(fs.FS, Options)`; `policy.go`: `ValidatePolicy`). Use stdlib only and add no dependencies. Makes T208 and T209 pass. +- [x] T211 Implement `cmd/tpa-corpus/main.go`, with subcommands `build` (writes `internal/security/scanner/bundled/scanner-bundle.json`), `verify` (rebuild and compare, exit non-zero on drift) and `validate --bundle --dataset ` (load layer plus policy layer). `cmd/tpa-corpus/main_test.go` covers the exit codes, test first. +- [x] T212 Migrate the six existing signatures: + - Create `internal/security/tpacorpus/signatures/manifest.json` and `TPA-2026-0001.json` to `TPA-2026-0006.json`. + - 0002 is `gating:false`. + - 0003 is re-classed to `tpa_sensitive_file_coaxing` in `signatures[]` only. + - Existing `rules[]` and `skipped[]` stay byte-identical. +- [x] T213 Write a failing test, `internal/security/tpacorpus/embedded_test.go` (`TestEmbeddedCorpus_*`): + - rebuilding from `signatures/` with the manifest pin equals `scanner.EmbeddedBundle()` byte for byte; + - the embedded bundle passes `ValidatePolicy` against `detect_corpus_v1.json`; + - the 10 v0.1 rules are present unchanged, so the CheckIDs that attack-lab and the runtime tests pin stay stable. +- [x] T214 Author the new signature sources `internal/security/tpacorpus/signatures/TPA-2026-0007.json` and onward, per T207, including the control. + - Every regex is inline `(?is)`, `regex` × `tool_description`, and RE2-safe. + - Before committing each regex, run `go test ./internal/security/scanner/ -run 'TestSEC01_RealWorldBenignCorpora_NoNewHolds|TestSEC01_VariantCorpus|TestCoverage_BenignNotHardBlocked'`. + - If a regex causes a regression, narrow it. **Never re-baseline** `testdata/sec01_realworld_baseline.json`. +- [x] T215 [P] Write a failing test by extending `specs/065-evaluation-foundation/datasets/detect_corpus_test.go`: + - derive the bundle classes in `validDetectCategory`, `gatedDetectCategories` and `hardNegPrefix` from `tpacorpus.Classes`; + - schema checks for `tpa_id` and `canonical`; + - no `hardNegPrefix` value is a prefix of another. +- [x] T216 Add the eval pairs to `specs/065-evaluation-foundation/datasets/detect_corpus_v1.json`: + - at least 1 malicious entry per gating signature (`tpa_id`, class category, `self-authored`); + - at least 2 `hn__*` hard negatives per class (security tooling, docs that quote attacks); + - one `canonical` per class. + - Update `specs/065-evaluation-foundation/datasets/README.md`: the composition table, which is stale (it says 32 and the file has 57), and the in-place-extension note. +- [x] T217 Regenerate the bundle with `SOURCE_DATE_EPOCH= go run ./cmd/tpa-corpus build`, setting `bundle_version` to `0.1.1`.

It must cover: + - with no `--bundle`, the metrics `checks` contain `tpa.bundle` and a new `bundle` block carries the fingerprint, runnable rules and signature count; + - `--bundle ` exits `4`; + - `--bundle ` exits `4` and never falls back to the embedded bundle; + - `TestCategoryCheck_CoversCorpusClasses`: every entry of `tpacorpus.Classes`, and every gating signature category in the embedded bundle, maps to `"tpa.bundle"` in `categoryCheck`. +- [x] T220 Implement the gate changes: + - `cmd/scan-eval/main.go`: the `--bundle` flag, with empty meaning the embedded bundle loaded through `scanner.LoadBundleCheck`. + - `cmd/scan-eval/gate.go`: + - `builtinGateChecks()` plus `gateChecks(bundle)`; + - `runGate(c, checks, …)`; + - static `categoryCheck` entries for every class; + - a `bundle` block in `gateMetrics`; + - a rewritten "MUST mirror" doc comment (the production surface is the hard built-ins plus `BundleCheck`, and the soft checks are unscored by design). + - Update the five `evaluateGateCorpus`/`runGate` call sites in `cmd/scan-eval/gate_test.go`. +- [x] T221 Write the control corpus `cmd/scan-eval/testdata/bundle_control_corpus.json` (D-US2-7). Its `description` names the control id and why it is the control. +- [x] T222 [P] Write `cmd/scan-eval/bundle_control_test.go` with two tests: + - `TestBundleControl_NoOverlap`: with `builtinGateChecks()` only, `Detected == 0`. With the full bundle, the finding's `Signals` hold exactly one `tpa.` id, the control's, and no hard negative is flagged. + - `TestBundleControl_RemovalBreachesGate`: `run()` with `--bundle ` exits `exitOK`. `run()` with `--bundle ` exits exactly `exitGateBreach`, and the test asserts the two recall values, 1.0 and 0.0. +- [x] T223 [P] Write `internal/security/scanner/tpa_control_overlap_test.go` (`TestBundleControl_NoProductionBuiltinHardFinding`). It reads `../../../cmd/scan-eval/testdata/bundle_control_corpus.json` and asserts that `baselineEngineChecks()` alone yields no `ThreatLevelDangerous` finding for the control sample. +- [x] T224 Run `go run ./cmd/scan-eval --corpus specs/065-evaluation-foundation/datasets/detect_corpus_v1.json --gate --min-recall 0.90 --max-fp 0.05`.
