+- Discovery Scope: Extension of the semantic layer (facts, shapes, store, MAP proposers), the entry-point mapper, reports, the pair corpus, leave-one-out and the improve lever; complex integration because it consumes two unimplemented upstream specs.
+- Key Findings:
   - The absence pairs are real and structured. `vampi-books-get-by-title` has identical code on both sides except a constraint `user=user` bound from `token_validator(request.headers.get('Authorization'))['sub']`; the vulnerable branch queries `Book` by title alone. The difference is the provenance of a constraint, not a flow. 15 of 29 `agent-vfc` rows and 6 of the 19 non-teaching `vibe-py` pairs carry absence labels (`missing_auth_guard`, `permissive_default`, `identity_from_request_body`, `secret_in_client`, `validation_strength`).
   - The entry-point mapper already classifies every route as `public`, `authenticated` or `role-restricted` from its decorators (`mapping._python_route_access`), records the decorators as `access_evidence`, and lists `conditions` (`if` tests that look like checks). That is the sibling detector's upstream for path guards and needs no change.
   - `FileIR` binds carry `value_text`, `names` and `call_name`; `variants.source_kind_of_name` already traces a name through binds to a fact source, a parameter or a container read. Provenance of a constraint's value (authenticated context versus request input versus constant) is the same trace with one more source class.

+- Feature: `corpus-seeded-mechanisms`
+- Discovery Scope: Extension of mechanism memory, MAP stage, pair eval, and the improve loop
+- Key Findings:
   - `semantic/mechanisms.py` already has `Mechanism`, `MechanismStore` (append-only JSONL), `append_mechanism`, embedding cache, hard filters by language/CWE/tags, and `order_promotions`. It is written only by `cli._append_proven_mechanisms` after a sandbox trigger, so it is empty on every real tree.
   - Clearwing's recall lever is the variant loop: a proven mechanism becomes a structural search over the messy tree. OpenUltraSAST copied the store and the retrieval, not the loop.
   - `FileIR` call sites already carry callee name, argument texts, argument identifier lists, and constant flags; binds carry source text and names. That is enough for a shape without new parsing.

 - **Cross-file registration context (amended during task 4.1).** Some frameworks keep the route table out of the handler module: connexion registers by `operationId` in an OpenAPI document, an Express application registers in a router file. A single-file excerpt of such a handler can never contain its registration, so Req 10.2 is unreachable for those rows without a second file. A recipe may therefore name `context = ["<repo-relative path>"]`; `benchmarks/pairs/harvest.py` fetches each document at the same two commits, extracts only the stanza that names the handler (`extract_registration_context`), and writes it under `<name>/context/<side>/<relpath>` with its own provenance header and the same redaction. The catalog carries `[[pair.context]]` rows, `PairCase.context_files` holds `(relpath, vuln, fixed)`, and `_materialize_side` copies them beside the excerpt at their repository-relative paths so the entry-point mapper sees the same layout the project has. `src/openultrasast/mapping.py` gains `_route_manifest_entry_points`, which reads `operationId` and the operation's `security` block out of a YAML or JSON document and attributes the record to the module the operation id points at. Trap pairs whose fixed side is a different, correctly guarded handler carry `fix_function` so the fixed side gets *its* registration rather than the vulnerable side's.

   - Every learning path ignores the split (`evaluate_profiles`, `evaluate_mechanism_profiles`, `propose_mechanism_edits`, `evaluate_loo`, `build_pair_signals`, `export_mechanisms`); one teacher rule fixes all of them.

 ### Decision: families are the only routing and scoring key

+- Feature: `pair-corpus-honesty`
+- Discovery Scope: Extension of the pair catalog, scorer, and harvest; supersedes `real-world-vfc-slice`
+- Key Findings:
   - The overlay scorer ignores `coverage`. The Java sqli vuln file already produces a coverage record on `prepareCall` from a servlet source; the scorer reports MISS.
   - The overlay column equals the inventory column on all 176 vfc pairs because C facts have no memory sink, so every proposal is `flow_incomplete` and the scorer falls back to inventory. The dashboard cannot show engine progress until the scorer reports parser and adjudication loss explicitly.
   - Harvest anchors on the first textual occurrence of the function name. For curl that is the doc comment mention (`Curl_follow()`), so 25 pairs start mid-comment and fail to parse.

Today the harness still *decides* with pattern inventory. The complexity map ranks; the sandbox can run; neither adjudicates "this sink is fed by a source" versus "this sink is hardcoded, sanitized, or unreadable."
 
 This feature splits the scan into three operator-visible roles that must not collapse: **regex proposes, semantics adjudicates, sandbox proves.** Labeled suites (cheat-sheet fixtures, OWASP Benchmark, Juliet, CVE pairs) remain **calibration**. They are not the definition of in-scope code.
 
 ## Boundary Context
 
-- **In scope**: Role split on `quick` / `standard` / `deep`; overlay dispositions; tree-sitter (and optional Joern) as the semantic engine; tunable retrieval/rank **before prove**; `unadjudicated` on messy files; sandbox only after promote; calibration vs unlabeled working trees.
-- **Out of scope**: Deleting pattern rules; making an LLM the adjudicator; rewriting CWE policy or project-score formula; requiring Joern or an embedding model for `quick`; auto-generated flow facts from the improve loop; treating benchmark Youden as a merge gate that can unblock a smoke-gate breach. Embedding rank is a **budget**, not a fourth verdict.
-- **Adjacent expectations**: Stage plan, complexity map, Docker sandbox, pair catalog, and 90/10 detection gate from `three-stage-scan` keep their contracts. This spec overlays adjudication on that pipeline; it does not replace stage accounting, sandbox flags, or `LANGUAGE_MANIFESTS`.

+- Discovery Scope: Complex Integration across semantic, mapping, rank, complexity, hunter, regress, improve
+- Key Findings:
   - `FunctionIR` already carries every call site per function for Python, JS, TS, C, and Java when the extra is present. A name-resolved call graph is a few hundred lines over data that exists.
   - Reachability today is "line inside an entry-point handler" (`mapping.attach_reachability_hints`); `rank` bumps an integer from tags and hints; `worth_fixing` needs `reachable` or `inferred-file-surface`. No call edge exists anywhere.
   - Sandbox candidates come only from hotspots filtered to overlay-promoted inventory ids (`cli.py:404`, `prove_filter.filter_promoted_hotspots`); a hunter snippet is used only for an already promoted hotspot (`candidate.py:199`). The LLM plane cannot create a candidate.

-- **Findings**: Because parameters are already seeded tainted, a per-function run already answers "which parameter reaches which sink." Adding "which parameter reaches the return" is a small extension. Composition is then a graph walk with a depth bound. Nothing needs alias analysis to produce a useful path; anything unresolved stays `flow_incomplete`.

 ## Risks & Mitigations

-- Graph blow-up on large trees — depth and fan-out bounds in config; hotspot caps unchanged.
-- Model answers wrong — never used unless accepted by the gate; provenance recorded; hand facts win.

 ## Problem
 
-Operators care whether the harness fires on a real buggy snapshot and stays quiet after the patch — Firefox, Chromium, OpenSSL — not whether OWASP BenchmarkTest00074 is a TP. The labeled SAST slice is 11 textbook files. Overlay Youden there is **worse** than inventory (+9.09% → 0%). We cannot tell if the tool got better on messy product code.

 ## Current State
 
-Slices today: `local` (CI 100%), `github` (6 vendored functions: SVEN, hutool, node-serialize), `sast` (OWASP/Juliet). `datasets.toml` already points at CVEfixes, MoreFixes, CWE-Bench-Java, Vul4J. Nothing is harvested from gecko-dev / Firefox. Whole mozilla-central is not in-tree (and should not be). FixFox (Zenodo) is embargoed until 2030. Firefox security commit messages are often scrubbed of “security” words, so grep-the-log is a bad miner.

-- **Key Findings**:
+- Feature: `real-world-vfc-slice`
+- Discovery Scope: Extension of the existing pair catalog and pair eval CLI
+- Key Findings:
   - Pair eval already concatenates `benchmarks/pairs/catalog.toml` with `sast/catalog.toml`. A third file `vfc/catalog.toml` is the smallest seam.
   - CLI `--slice` choices are a closed set (`all`, `local`, `github`, `sast`). `vfc` must be added there and in tests that assert slice names.
   - `sast` already scores overlay with inventory fallback when nothing is promoted or demoted. `vfc` should use that path as the primary scorer and add a second inventory-only figure for the honesty dashboard.
   - `pair_gate` evaluates the full catalog but fails CI only on `local` 100%. Adding vfc pairs does not change the fail condition if names stay out of `LANGUAGE_MANIFESTS`.
-  - Seed commits with public VCS snapshots exist: OpenSSL Heartbleed (`tls1_process_heartbeat`), Firefox libmar (`mar_insert_item`, CVE-2020-15667), Chromium FileReader (`ArrayBufferResult`, CVE-2019-5786). All three keep a sink-shaped call after the fix, so overlay/inventory may LEAK — that is the dashboard, not a 100% gate.

 ## Research Log
 
 ### Existing pair catalog and scoring
 
-- **Context**: Brownfield extension; must not invent a second eval engine.
-- **Sources Consulted**: `src/openultrasast/pairs.py`, `cli.py`, `pair_gate.py`, `tests/test_pair_corpus.py`, `benchmarks/pairs/catalog.toml`, `benchmarks/pairs/sast/catalog.toml`, `benchmarks/pairs/README.md`

+- Findings:
   - `PairCase.slice` is a free string in the catalog loader; the closed set lives only in argparse and tests.
   - Overlay pair eval is gated on `case.slice == "sast"`.
   - GitHub pairs already use provenance comments plus catalog fields (`repo`, `commit`, `commit_url`, `cve`, `license`).
   - Pair names must not appear in `LANGUAGE_MANIFESTS`.
-- **Implications**: Add `vfc` as a concatenated catalog; extend the overlay branch to `sast` **or** `vfc`; keep the gate local-only.

+- Findings:
   - Heartbleed fix adds a record-length check; `memcpy(bp, pl, payload)` remains. Inventory `c-unsafe-memory-copy` will fire on both sides (LEAK) until CWE-121 semantics exist.
   - Firefox fix is `int namelen` → `uint32_t namelen`; `memcpy(item->name, name, namelen + 1)` remains. Same LEAK class.
   - Chromium fix copies the ArrayBuffer on partial results (UAF). No memcpy/eval sink; expected MISS on inventory and overlay. Still a labeled pair.
   - GitHub raw and Phabricator `?diff=1` return the function text without cloning.
-- **Implications**: Seed three reviewed pairs. Tests assert presence and that the slice **runs**, not that pair_correct is 100%. Memory-safety pairs are allowed as known leaks (Req 6.3).

   - Stage 2 is not a hunter dump and is not `RankingScore`. Ranking is per-file attention. A complexity map is per-file-and-function hotspot attention plus test-gap hints. Existing signals (tags, loc, reachability hints, finding density, `has_fuzz_entry_point`) are enough for a heuristic map; the tool-using hunter refines it.
   - Stage 3 has config and a threat-model table, but `cli.py` exits on `--mode deep`. No container is ever started. The first execution of untrusted code must be Docker CLI with the documented isolation flags, not a Python SDK and not host `subprocess` of target code.

-- **Sources Consulted**: `src/openultrasast/cli.py` (`_run_scan`, mode choices), `README.md` maturity legend, `.kiro/specs/openrouter-sast-harness/requirements.md` (hunter pool, docker sandbox, dynamic analysis), `.kiro/specs/harnessx-self-improving-rulesets/design.md`.

+- Findings:
   - `quick` is implemented and deterministic. `standard` schedules a hunter pool that calls `quick_scan_findings` unless HarnessX extra + hunter model are set. `deep` raises `SystemExit`.
   - OpenRouter spec already defined: quick = static + bounded LLM review; standard = sandboxed tool-calling hunters; deep = harness/fuzz/dynamic. Implementation never reached that.
   - Existing CI and README teach `--mode`. A parallel `--stage` flag would fork the contract.

+- Findings:
   - Ranking is file-level and exists to budget the hunter. It does not name functions, test gaps, or "tune your tests."
   - Tags already encode likely problem classes (`memory_unsafe`, `parser`, `network_entry`, `syscall_entry`). Loc ≥ 500 boosts influence. No nesting/branch signal. No test-file presence.
   - A hotspot that stage 1 missed (split-sink) can still rank high if the file is a reachable parser. That is the point of stage 2.
-- **Implications**: Keep `RankingScore`. Add `ComplexityMap` / `Hotspot` with function identity when recoverable, test-gap hints, and a ledger overlay. Ranking still feeds hunter budgets; the map feeds humans and stage 3.

 ### Hunter: regex, HarnessX dump, or tools
-- **Context**: Previous spec adopted HarnessX "at the hunter loop" but the default hunter is regex and the HarnessX path dumps source into a prompt.
-- **Sources Consulted**: `hunter.py` (`_run_hunter_task` → `quick_scan_findings`), `hunter_harness.py` (`_describe`, `_extract_findings`), `provider/openrouter.py` (`OpenRouterChatClient.complete_json`, stdlib `urllib`), `harness_ext.py` (optional extra).

+- Findings:
   - OpenRouter client is already zero-extra (stdlib). It is used for optional ranking, not for hunting.
   - HarnessX extra is SHA-pinned, heavy, absent in CI. Requiring it repeats the last spec's failure mode.
   - Clearwing hunters use `read_source_file`, `grep_source`, `find_callers` with path clamping. That is the evolutionary piece, not MetaAgent regex-status flips.
-- **Implications**: Stage 2/3 hunter is a bounded tool loop over the OpenRouter client (or HarnessX if already wired). Tools are stdlib (read, Python grep, caller search from mapping + text). Path clamp at repo root. Hunter output evidence = `suspicion`.

+- Findings:
   - Python `docker` SDK would be a new core or extra dependency. The operator already has the Docker CLI if they can run containers.
   - Subprocess `docker run --rm --init` with bind-mount of the repo read-only and a tmpfs/scratch write area matches the threat model and keeps `dependencies = []`.
   - Unit tests must not require a daemon: inject a `SandboxRunner` protocol, ship a fake. Integration tests skip when `docker info` fails.
   - Full sanitizer-image builds (Clearwing) are out of scope for this spec. Stage 3 runs language-specific commands on a small pinned image per language family, or `inconclusive` if the recipe is missing.

+- Findings:
   - Stage 1 smoke fixtures are still useful as unit tests. They must not be the stage 2/3 merge gate.
   - A split-sink corpus is small and owned: source and sink on different lines; mutations through wrappers/variables. Success = map ranks the true function in the top band; stage 3 triggers at least one stage-1 miss when Docker is present.
   - Comparing map ranking to "sort by pattern-hit count" is an anti-cheat-sheet test: if regex density is the map, the gate fails.

+- Sources Consulted: `skills.py` (`STAGES = ("map", "hunt", "verify", "fix")`), `mcp.py:68` (rejects `deep`), `reports.py:115` (`scan_exit_code`), `mapping.py` (no Java/Groovy AST), `config.py` (`SandboxConfig` parsed, never consumed by `_run_scan`), `rank.py` (`rank_targets_with_model` unused by CLI).
+- Findings:
   - Trail of Bits skill routing already uses a stage named `map` (mapping-discipline skills: Semgrep/CodeQL/sharp-edge). That is not the complexity map. `stages.py` must not reuse `skills.STAGES`.
   - MCP scan tools reject `deep` and forbid docker/shell. This spec does not widen the MCP surface; deep is CLI/CI only.
-  - `--fail-on` is implemented in `scan_exit_code`, not only argparse. `worth-fixing` must be added there.

 ## Design Decisions
 
 ### Decision D1: Modes map to stages
-- **Context**: Need a three-question scan without breaking CI that already passes `--mode`.
-- **Selected Approach**: `quick`→stage 1, `standard`→1+2, `deep`→1+2+3. Manifest records both.
-- **Rationale**: Evolutionary adoption of the CLI the project already shipped.
-- **Trade-offs**: Operators must learn that `standard` now means "map" not "regex hunter pool." README must say so.

+- Trade-offs: Operators must learn that `standard` now means "map" not "regex hunter pool." README must say so.
 
 ### Decision D2: Docker CLI subprocess, no SDK
-- **Context**: Zero-dep core vs isolated execution.
-- **Selected Approach**: `docker` binary via `subprocess`; probe with `docker info`; fake runner in unit tests.
-- **Rationale**: Operator runtime, not a Python dependency. Matches threat-model flags.
-- **Trade-offs**: Windows/macOS Docker Desktop variance; integration tests skip without a daemon.

 ### Decision D3: OpenRouter client for the tool hunter; HarnessX optional
-- **Context**: Last spec hid the LLM behind an extra CI does not install.
-- **Selected Approach**: Tool loop calls `OpenRouterChatClient` (or any `RankerClient`-shaped chat client) when `[models].hunter` is set. If HarnessX extra is present, `HxScanOrchestrator` may host the same tools; it is not required.
-- **Rationale**: Evolutionary use of code already in tree. Stdlib HTTP.
-- **Trade-offs**: Two possible runtimes until HarnessX is either used or ignored; tests mock the client.

+- Rationale: Evolutionary use of code already in tree. Stdlib HTTP.
+- Trade-offs: Two possible runtimes until HarnessX is either used or ignored; tests mock the client.
 
 ### Decision D4: Complexity map is a new artifact
-- **Context**: Ranking already exists.
-- **Selected Approach**: `ComplexityMap` with `Hotspot` records. Ranking remains the hunter budget. Map is what humans and stage 3 consume.
-- **Rationale**: Different question (where to look / how to test vs which file to hunt first).

 ### Decision D5: Worth-fixing is a gate, not an evidence level
-- **Context**: Evidence ladder is already six rungs. Do not invent a seventh for CI.
-- **Selected Approach**: Verdicts `triggerable|not_triggerable|already_covered|inconclusive` → `worth_fixing|not_worth_fixing`. Evidence levels unchanged. Hunter stays at `suspicion`.

+- Rationale: CI owners need a fail-on that means "we proved it," without collapsing the ladder.
 
 ### Decision D6: Split-sink / mutation gate for stages 2–3

-- **Selected Approach**: `.openultrasast/calibration/complexity_ledger.json` keyed by `repo_fingerprint + path + function`. Triggerable boosts, not_triggerable demotes. Cannot hide reachable severity-5 inventory from worth-fixing consideration.

+- Rationale: Same overlay pattern as `rule_policy.json`, different object.
 
 ### Decision D8: Language recipes, not a universal executor
-- **Context**: Running untrusted Python vs C vs Java is different.
-- **Selected Approach**: Small recipe registry (Python and JavaScript required for MVP; C compile+run when a compiler exists in the image; Java `inconclusive` until a recipe ships). Missing recipe → `inconclusive`, not a crash.
-- **Rationale**: Simplification. Do not build Clearwing's sanitizer image matrix in this spec.

 ## Synthesis
 
-- **Generalization**: Inventory → attention → proof is one pipeline with a `StagePlan`. Map, hints, and regress are processors on that plan, not three products.
-- **Build vs adopt**: Adopt Docker CLI and the in-tree OpenRouter client. Build the map, ledger, recipes, and split-sink corpus. Do not adopt Clearwing, docker SDK, or a cyclomatic-complexity library (nesting depth from indentation/braces is enough).
-- **Simplification**: No `--stage` flag, no HarnessX requirement, no fuzz campaign, no patch oracle, no Python Docker extra.

 ## Risks & Mitigations
-- Docker-in-Docker / rootless CI — probe, skip stage 3, degrade; do not fail stage 1.
-- Hunter cost on large repos — hotspot cap + existing `[harnessx] max_cost_usd` / hardening `max_findings` / new `max_regress_candidates`.
-- Untrusted snippet execution — structural deny (network, writes outside scratch, curl, docker socket mount). Never mount `/var/run/docker.sock`.
-- Stage 2 still heuristic without a model — allowed; gate is ranking quality on split-sink, which heuristics can pass if tags+reachability work.
-- Breaking `deep` from "exits" to "runs" — intended; document in README.

 ### Probe vs grammar
 
-- **Context**: `tree_sitter_available()` is true when CLI is on PATH with zero grammars.
-- **Findings**: CLI parse cannot populate `FileIR` without a walker. Extra Python API is the product parse.
-- **Implications**: Split `has_semantic_extra()` from per-language `grammar_for`. Remove CLI as a success path.

 ### Decision: Adopt official grammar wheels, build one walker
 
-- **Context**: Avoid per-language AST visitors (Req 4).
-- **Alternatives**: tree-sitter CLI sexp; py-tree-sitter-languages (unmaintained); hand-rolled JS/C parsers.
-- **Selected**: `openultrasast[semantic]` = `tree-sitter` plus python/javascript/c/cpp/java grammar packages. One CST walk keyed by a node-kind map.
-- **Rationale**: Wheels are MIT, maintained, match in-scope languages. Taint stays language-agnostic.
-- **Trade-offs**: Native wheels in the extra; ABI pins. Core install stays empty.
-- **Follow-up**: Verify Parser constructor against the pinned `tree-sitter` minor at implement time.

-- **Selected**: If `tree.root_node.has_error` (or ERROR children), return `FileIR(parse_ok=False, reason=parse_failed)`.

 ## Synthesis
 
-- **Generalization**: One `parse_file` dispatch; extra is a grammar source, not a second overlay.
-- **Build vs adopt**: Adopt tree-sitter wheels; build only the FileIR projection (binds/calls).
-- **Simplification**: No CLI sexp walker; no second parse API; no taint/overlay changes.

 ## Risks & Mitigations
 
-- Grammar ABI mismatch — pin extras together; extra-on CI job catches import/parse failure.
-- Node-type drift — table in cst.py; tests assert JS eval and C printf on real trees.
-- CLI still on PATH — must not set parse_ok.
