feat(benchmark): valid detection benchmark spec + offline modules (groups 1-4)
Builds the benchmark from .kiro/specs/valid-detection-benchmark/brief.md:
sound labels from the fix (no SZZ), app-shaped verified positives,
ordinary negatives from the same repos, whole tool on unseen repos,
standard metrics.
Spec: requirements.md, design.md, tasks.md. Reuses the existing sourcing,
fix-site labelling, negative drawing, replay, and Wilson scoring; drops
the SZZ layer.
New offline modules under benchmarks/valid/:
- catalog.py positives labelled at the fix site (never introducing/last_touch)
- verify.py one LLM call per case (vulnerable? fix addresses it? reachable
in-repo?) + human spot-check; this is the app-shaped filter.
Honors the instrument rule: bytes read per function, reject on
an empty read.
- assemble.py >=20x ordinary negatives + a frozen, deterministic manifest with
the held-out guard
- metrics.py precision (PPV), false alarms per 100 pushes, exploit-verified
rate, and the plain headline, layered on score.py
36 new offline tests, 495 regression tests green. No network, no harvest,
no model calls in tests. Group 5 (the live pilot) is not started.

# Design: valid detection benchmark
|
||||||
|
|
||||||
|
Builds the benchmark in R1-R8. New code lives under `benchmarks/valid/`. It reuses the sourcing,
|
||||||
|
labelling, negative-drawing, replay, and scoring that already exist, and drops the SZZ layer.
|
||||||
|
|
||||||
|
## What is reused and what is new
|
||||||
|
|
||||||
|
Reused as-is:
|
||||||
|
- Sourcing advisories to repos and fix commits: `benchmarks/unseen/source.py`, `draft.py`,
|
||||||
|
`eligibility.py` (the used-set held-out guard).
|
||||||
|
- Fix-site labelling: `benchmarks/unseen/extract.py:fix_sites()` and the pair builder in
|
||||||
|
`benchmarks/pairs/advisory-fixes/` (`materialize.py`, `catalog.toml`, `verification.json`).
|
||||||
|
- Function cutting: `openultrasast.learn.excerpt.function_bounds`.
|
||||||
|
- Ordinary negatives: `extract.py:ordinary_history()` and `draw_ordinary()`.
|
||||||
|
- Replay: `benchmarks/unseen/replay.py` and `replay_entry.py` (whole tool via the push hook).
|
||||||
|
- Scoring base: `benchmarks/unseen/score.py` (catch, false alarm, Wilson, repo-clustered interval,
|
||||||
|
required_n, McNemar gate).
|
||||||
|
|
||||||
|
New:
|
||||||
|
1. `benchmarks/valid/catalog.py` - sourcing to a fix-site positive catalog, SZZ paths excluded.
|
||||||
|
2. `benchmarks/valid/verify.py` - the committed LLM verification driver (replaces the scratchpad
|
||||||
|
`label_audit.py`). One call per case confirms vulnerable / fix-addresses / reachable-in-repo. This is
|
||||||
|
also the app-shaped filter: reachability is answered here, not by a separate classifier.
|
||||||
|
3. `benchmarks/valid/metrics.py` - precision, false alarms per 100 pushes, and exploit-verified rate,
|
||||||
|
layered on `score.py` output.
|
||||||
|
4. `benchmarks/valid/assemble.py` - freezes the verified positives plus the negative draw into a
|
||||||
|
replay manifest with a digest and the held-out guard.
|
||||||
|
|
||||||
|
## Data flow
|
||||||
|
|
||||||
|
```
|
||||||
|
advisories (OSV/GHSA)
|
||||||
|
-> source.py / draft.py resolve repo + fix commit + parent [reuse]
|
||||||
|
-> catalog.py fix-site label (no SZZ); emit candidate cases [new, wraps extract.fix_sites + pairs materialize]
|
||||||
|
-> verify.py LLM: vulnerable? fix addresses it? reachable in-repo? + confidence [new]
|
||||||
|
-> human spot-check record decision, reviewer, date [manual, recorded in verification.json]
|
||||||
|
-> draw_ordinary() negatives from the same repos [reuse]
|
||||||
|
-> assemble.py freeze positives+negatives -> manifest + digest, held-out guard [new, wraps eligibility.normalize]
|
||||||
|
-> replay.py (docker lane) run the whole tool at push time [reuse]
|
||||||
|
-> score.py + metrics.py recall, precision, FP/100, exploit-verified, intervals [reuse + new]
|
||||||
|
```
|
||||||
|
|
||||||
|
## Schemas
|
||||||
|
|
||||||
|
### Positive case (catalog.py output, extends `advisory-fixes/catalog.toml`)
|
||||||
|
```
|
||||||
|
[[case]]
|
||||||
|
id = "owner-repo-cve"
|
||||||
|
repo = "owner/repo"
|
||||||
|
url = "https://github.com/owner/repo"
|
||||||
|
advisory = "GHSA-xxxx / CVE-xxxx"
|
||||||
|
cwe = "CWE-89"
|
||||||
|
family = "sql_injection"
|
||||||
|
language = "python"
|
||||||
|
commit = "<fix sha>" # post-fix (safe) side
|
||||||
|
parent = "<parent sha>" # pre-fix (vulnerable) side
|
||||||
|
path = "app/db.py"
|
||||||
|
function = "get_member_by_code"
|
||||||
|
function_lines = [[40, 58]]
|
||||||
|
method = "fix_site" # never introducing/last_touch
|
||||||
|
```
|
||||||
|
|
||||||
|
### Verification record (verify.py output, extends `advisory-fixes/verification.json`)
|
||||||
|
```
|
||||||
|
{ "id": "...", "vulnerable_pre_fix": true, "fix_addresses_it": true,
|
||||||
|
"reachable_in_repo": true, "entry_point": "flask route /member/<code>",
|
||||||
|
"confidence": 0.86, "model": "deepseek-...", "advisory_cited": true,
|
||||||
|
"human_spot_check": {"decision": "accept", "reviewer": "<initials>", "date": "2026-10-13"},
|
||||||
|
"verdict": "accepted" } # accepted only if all three true AND human accept
|
||||||
|
```
|
||||||
|
|
||||||
|
### Replay manifest (assemble.py output)
|
||||||
|
A `pool.toml`-shaped file so `replay.py` consumes it unchanged: `[[repository]]` rows with `changes`,
|
||||||
|
each change `kind = "vulnerability"` (positives, label from fix) or `kind = "ordinary"` (negatives),
|
||||||
|
with `base`/`head`/`files`/`function`. A `freeze-valid.json` carries the freeze digest and the held-out
|
||||||
|
guard result, matching the SZZ pool's freeze format so the ledger and replay flow are identical.
|
||||||
|
|
||||||
|
## Metrics (metrics.py)
|
||||||
|
|
||||||
|
Input is the scored records from `score.py`. New outputs:
|
||||||
|
- **precision** = flagged-and-real / all-flagged, over positives and negatives together, with Wilson 95%.
|
||||||
|
- **false alarms per 100 pushes** = false-positive rate x 100, the presentation of `score.py`'s
|
||||||
|
`false_alarm` rate. This is a presentation layer, not a new measurement.
|
||||||
|
- **exploit-verified rate** = of flagged positives, the share the search-with-proof arm
|
||||||
|
(`src/openultrasast/search/`) demonstrates on the vulnerable side and not the fixed side. Joined by
|
||||||
|
case `id` from a proof-arm run; absent where the arm has not run (reported as "not yet proved", not as
|
||||||
|
a failure).
|
||||||
|
|
||||||
|
Headline string, built here:
|
||||||
|
> "On unseen app repos: recall X% (Wilson A-B), false alarms Y per 100 pushes, precision Z%; exploit-verified N of M."
|
||||||
|
|
||||||
|
## Verification driver (verify.py) details
|
||||||
|
|
||||||
|
- Model: DeepSeek via the shipped provider, off-cluster (cheap, ~$0.0002/call). The brain tier runs
|
||||||
|
locally in research; it does not need the kube engine.
|
||||||
|
- Prompt inputs per case: the advisory text, the pre-fix function, the post-fix function, and the file
|
||||||
|
context around the function (for the entry-point question). No repo-wide context in the first version.
|
||||||
|
- Output is the verification record above. Reachability uses the same entry-point and source concepts the
|
||||||
|
taint engine already models (`src/openultrasast/ruleset/frameworks.py`, framework routes/handlers), so
|
||||||
|
the LLM is asked a concrete question, not an open one.
|
||||||
|
- Instrument rule: the driver prints bytes read for each side's function before it calls the model, and
|
||||||
|
fails loudly on an empty read. A verdict on an unread case is rejected. (AGENTS.md instrument rule.)
|
||||||
|
|
||||||
|
## First increment (pilot)
|
||||||
|
|
||||||
|
1. Source Python and JS advisories with a clean fix link, held out from the tool's training/mining sets.
|
||||||
|
2. `catalog.py` builds candidate cases by fix site. Target ~25 candidates to land ~12 verified.
|
||||||
|
3. `verify.py` runs the LLM check; human spot-checks all of them (dozens, so full review is cheap).
|
||||||
|
4. `draw_ordinary()` draws >=20x negatives from the same repos.
|
||||||
|
5. `assemble.py` freezes the manifest + digest + held-out guard.
|
||||||
|
6. `replay.py` on the Docker lane runs the whole tool.
|
||||||
|
7. `score.py` + `metrics.py` produce the four metrics with intervals and the headline.
|
||||||
|
|
||||||
|
The pilot proves the pipeline and gives the first real numbers. Then grow positives to ~40 (set exactly
|
||||||
|
by `required_n`) and, where the proof arm has run, fill in the exploit-verified rate.
|
||||||
|
|
||||||
|
## Risks
|
||||||
|
- Harvesting is rate-bound (GitHub 5k/hr) and infra is operator-owned; the sourcing step runs
|
||||||
|
deliberately, not in a tight loop, and reuses the banked resolver.
|
||||||
|
- The LLM verifier can be wrong; the human spot-check is the backstop, and the proof arm is the
|
||||||
|
label-free check above it.
|
||||||
|
- App-shaped is a judgement call; record the entry point the verifier names so a human can audit it.

# Requirements: valid detection benchmark
|
||||||
|
|
||||||
|
Turns `brief.md` into testable requirements. The brief supersedes the retired SZZ pool
|
||||||
|
(`unseen-repo-evaluation`). This spec builds a benchmark with sound ground truth and standard
|
||||||
|
security metrics.
|
||||||
|
|
||||||
|
## Scope decisions (resolving the brief's open questions)
|
||||||
|
|
||||||
|
- **First-slice size.** Build a pilot of 10 to 12 verified positives end to end first, to prove the
|
||||||
|
pipeline, then grow to a target of about 40 verified positives. 40 gives a recall interval of roughly
|
||||||
|
±0.10 at a true recall near 0.85 to 0.90; `score.py:required_n(p, width)` computes the exact number,
|
||||||
|
so the target is set from that, not guessed.
|
||||||
|
- **Negative-to-positive ratio.** At least 20 ordinary commits per positive, drawn from the same repos.
|
||||||
|
Negatives are free to collect, and false alarms decide adoption, so err large. Report false alarms as
|
||||||
|
a rate per 100 pushes.
|
||||||
|
- **Languages first.** Python and JavaScript/TypeScript web applications (Flask, Django, FastAPI,
|
||||||
|
Express, Koa). These are where the tool is strongest and where in-repo entry points are clear. PHP and
|
||||||
|
others come later, named explicitly as not yet covered.
|
||||||
|
- **Curation record.** Each case stores the advisory, repo, fix commit, parent, path, function, the
|
||||||
|
pre-fix and post-fix excerpts, the LLM verdict with confidence, and the human spot-check decision with
|
||||||
|
reviewer and date. The set is frozen with a digest, the same way `advisory-fixes/` freezes its pairs.
|
||||||
|
- **Lane.** Curate and score locally on the Docker lane (research is local execution). The kube `ax`
|
||||||
|
lane stays the scale target but is not required here and is still blocked on the gVisor checkpoint path.
|
||||||
|
|
||||||
|
## Requirements
|
||||||
|
|
||||||
|
### R1. Positives labelled from the fix, never from SZZ
|
||||||
|
- Take the vulnerability location from the security fix: the file and function the fix changed, read at
|
||||||
|
the parent commit (pre-fix).
|
||||||
|
- Do not run SZZ blame walk-back. The sourcing must not use `extract.py`'s `introducing` or `last_touch`
|
||||||
|
methods. Use the fix site directly (`fix_sites()`) and first-parent history only.
|
||||||
|
- Each positive is a pair: the vulnerable function at `parent`, and the same function at the fix commit.
|
||||||
|
|
||||||
|
### R2. App-shaped and reachable in-repo
|
||||||
|
- Keep a positive only if the vulnerability is reachable from an entry point inside the repo: a web
|
||||||
|
route, a request handler, or a CLI argument.
|
||||||
|
- Drop library-internal cases whose trigger depends on a caller outside the repo. A pre-push tool cannot
|
||||||
|
see that trust boundary, so scoring it there is unfair.
|
||||||
|
|
||||||
|
### R3. Every positive is verified
|
||||||
|
- Verify each case with an LLM adjudication call and a human spot-check. The call must confirm:
|
||||||
|
(a) the pre-fix code is vulnerable, (b) the fix addresses it, (c) it is reachable from an in-repo entry
|
||||||
|
point.
|
||||||
|
- Record the verdict, the confidence, and the human decision. A case that fails any of (a), (b), (c), or
|
||||||
|
the human spot-check does not enter the benchmark.
|
||||||
|
|
||||||
|
### R4. Negatives are ordinary commits from the same repos
|
||||||
|
- Draw non-fix commits from the first-parent history of the same application repos, excluding the fix.
|
||||||
|
- The negative set is at least 20x the positive set.
|
||||||
|
|
||||||
|
### R5. Held out
|
||||||
|
- No repository in the benchmark was used to build, train, tune, mine, or harvest the tool. Enforce this
|
||||||
|
with the existing used-set canonicalization (`eligibility.normalize`), the same guard the SZZ pool used.
|
||||||
|
|
||||||
|
### R6. Measure the whole tool on unseen repos
|
||||||
|
- Run the tool as a developer runs it at push time: quick rules on, engine on, LLM-guided arm on.
|
||||||
|
- Use the existing replay harness so the measured path is the shipped push hook.
|
||||||
|
|
||||||
|
### R7. Standard metrics
|
||||||
|
- Report recall (true-positive rate), precision (positive predictive value), false-positive rate as
|
||||||
|
false alarms per 100 pushes, and exploit-verified rate (the share of flagged positives the proof arm
|
||||||
|
demonstrates with a working proof of concept).
|
||||||
|
- Report recall with a Wilson 95% interval and a repo-clustered interval, reusing `score.py`.
|
||||||
|
- The headline pairs recall and false alarms per 100 pushes in one plain sentence.
|
||||||
|
|
||||||
|
### R8. Reproducible and frozen
|
||||||
|
- The positive catalog, the negative draw, and the held-out guarantee are frozen with digests so a run is
|
||||||
|
reproducible. Re-running the freeze on an unchanged source yields the same digest.
|
||||||
|
|
||||||
|
## Non-goals
|
||||||
|
- No SZZ, no frozen-pool catch/false-alarm numbers (retired).
|
||||||
|
- No new detection capability in this spec. This measures the tool that exists.
|
||||||
|
- Not required to run on kube `ax` to be valid; the Docker lane is enough for the first numbers.
|
||||||
|
|
||||||
|
## Acceptance
|
||||||
|
- A frozen pilot of at least 10 verified positives plus their negatives, on held-out Python/JS repos,
|
||||||
|
run through the whole tool, producing recall, precision, false alarms per 100 pushes, and
|
||||||
|
exploit-verified rate, with intervals. Every positive has an LLM verdict and a human spot-check on
|
||||||
|
record.

# Tasks: valid detection benchmark
|
||||||
|
|
||||||
|
Order is dependency order. Each task is small enough to review on its own. New code under
|
||||||
|
`benchmarks/valid/`. Implementation goes through Codex, gated here.
|
||||||
|
|
||||||
|
## Group 1 - positive catalog (fix-site, no SZZ)
|
||||||
|
- [x] 1.1 `benchmarks/valid/catalog.py`: given sourced advisories (reuse `source.py`/`draft.py` output),
|
||||||
|
build candidate positive cases by fix site. Wrap `extract.fix_sites()` + `pairs/materialize.py`; read
|
||||||
|
the pre-fix function at `parent` and the post-fix function at `commit`. Must not call `introducing` or
|
||||||
|
`last_touch`. Emit the `[[case]]` catalog in the design schema. (R1)
|
||||||
|
- [x] 1.2 Filter to Python and JS/TS only; attach `language` and `family`/`cwe`. (scope decision)
|
||||||
|
- [x] 1.3 Offline test: a fixture commit yields one case with the correct pre/post functions and
|
||||||
|
`method = "fix_site"`; assert SZZ methods are never invoked.
|
||||||
|
|
||||||
|
## Group 2 - LLM verification driver
|
||||||
|
- [x] 2.1 `benchmarks/valid/verify.py`: one DeepSeek call per case via the shipped provider (off-cluster).
|
||||||
|
Confirm vulnerable-pre-fix, fix-addresses-it, reachable-in-repo; name the entry point; return
|
||||||
|
confidence. Print bytes read per function before the call; reject a verdict on an empty read. (R3, instrument rule)
|
||||||
|
- [x] 2.2 Emit the verification record (design schema) to `verification.json`; `verdict = "accepted"`
|
||||||
|
only when all three checks pass. Reachability here is the app-shaped filter. (R2, R3)
|
||||||
|
- [x] 2.3 Human spot-check hook: a small CLI to record accept/reject + reviewer + date per case into the
|
||||||
|
same record. (R3)
|
||||||
|
- [x] 2.4 Offline test with a stub model: a case with all three true and a human accept becomes
|
||||||
|
`accepted`; any false, or a human reject, does not.
|
||||||
|
|
||||||
|
## Group 3 - negatives and assembly
|
||||||
|
- [x] 3.1 `benchmarks/valid/assemble.py`: draw negatives with `extract.draw_ordinary()` from the accepted
|
||||||
|
positives' repos, at least 20x, excluding the fix. (R4)
|
||||||
|
- [x] 3.2 Freeze accepted positives + negatives into a `pool.toml`-shaped manifest + `freeze-valid.json`
|
||||||
|
digest; run the held-out guard via `eligibility.normalize`. (R5, R8)
|
||||||
|
- [x] 3.3 Offline test: freeze is deterministic (same source -> same digest); held-out guard drops any
|
||||||
|
repo in the used set.
|
||||||
|
|
||||||
|
## Group 4 - metrics
|
||||||
|
- [x] 4.1 `benchmarks/valid/metrics.py`: precision (PPV) with Wilson 95% over positives+negatives. (R7)
|
||||||
|
- [x] 4.2 False alarms per 100 pushes as the presentation of `score.py`'s false-alarm rate. (R7)
|
||||||
|
- [x] 4.3 Exploit-verified rate: join flagged positives with a search-with-proof run by case `id`;
|
||||||
|
report "not yet proved" where absent. (R7)
|
||||||
|
- [x] 4.4 Build the headline string (recall + FP/100 + precision + exploit-verified). (R7)
|
||||||
|
- [x] 4.5 Offline test on a tiny hand-made record set: all four metrics and intervals match hand calcs.
|
||||||
|
|
||||||
|
## Group 5 - pilot run (research, local)
|
||||||
|
- [ ] 5.1 Source Python/JS advisories; run `catalog.py` to ~25 candidates. (deliberate, rate-aware)
|
||||||
|
- [ ] 5.2 Run `verify.py` + human spot-check to land ~12 accepted positives.
|
||||||
|
- [ ] 5.3 `assemble.py` freezes the pilot manifest + negatives (>=20x) + held-out guard.
|
||||||
|
- [ ] 5.4 `replay.py` on the Docker lane, whole tool on (quick + engine + LLM arm).
|
||||||
|
- [ ] 5.5 `score.py` + `metrics.py`: produce recall, precision, FP/100, exploit-verified, intervals, and
|
||||||
|
the headline. Freeze the run under `benchmarks/measurements/`.
|
||||||
|
- [ ] 5.6 Write up the pilot: the four numbers, what they mean, and the target set size from `required_n`
|
||||||
|
for the full ~40-positive benchmark.
|
||||||
|
|
||||||
|
## Out of this spec
|
||||||
|
- Growing beyond the pilot to the full set (follow-up, once the pipeline is proven).
|
||||||
|
- Running on kube `ax` (blocked on gVisor; Docker lane is enough here).
|
||||||
|
- Any new detection capability.
