Marius CiepluchandClaude Fable 5.1 3c36f13e03 feat(pair-corpus-honesty): LLM-generated Real-Vuln repos and unlicensed agent fixes as pointer pairs

Task 8.4 (Req 10.6, 5.1).

- harvest.merge_recipes appends recipes by name and never rewrites
  existing rows.
- vibe-py/build_recipes.py --pointers: the 40 LLM-generated repositories
  without a license become vendored = false rows (80 pairs, agent,
  seeded) appended to recipes.toml; unlicensed human repos stay skipped.
- agent-vfc/build_recipes.py --from ... --pointers [--cache]: unlicensed
  agent-authored fixes become title-tier pointer rows whose function
  label is derived from the cached excerpt (30 added from a fresh
  662-candidate search); TOML booleans rendered correctly.
- catalogs regenerated: vibe-py 115 rows (35 vendored + 80 pointer),
  agent-vfc 59 (29 + 30); no excerpt is vendored for any pointer row.
- `pairs --slice vibe-py --pointers` scores both provenances (human 35,
  agent 80); the default run skips 80 pairs with pointer_pair_skipped;
  suite and gates unchanged. README/docs name the nightly command.

Raw Blame History

End-to-end examples

Each example is self-contained. Artifacts land under <target>/.openultrasast/runs/<scan-id>/ and .openultrasast/ is gitignored.

1. Quick scan a local repo (deterministic, no keys)

uv run ousast scan /path/to/code --mode quick
run=/path/to/code/.openultrasast/runs/<scan-id>
cat  "$run/report.md"       # findings + evidence (secrets redacted)
jq . "$run/score.json"      # 0–100 project score + gate verdict
"$run/report.sarif"         # SARIF for code-scanning / IDEs

2. CI gate

# Fail the build on any evidence-verified finding:
uv run ousast scan . --mode quick --fail-on verified

# The hard detection gate (>=90% recall, <10% FP), score-independent:
uv run python -m openultrasast.gate

3. Benchmark a known-vulnerable corpus

uv run ousast benchmark benchmarks/manifests/python-vulnerable.toml --mode quick
# -> expected / matched / missed counts + a per-rule recommendation delta

4. Vuln vs fixed pair eval (efficiency, not cheat-sheet recall)

uv run ousast pairs                              # local fixtures + vendored GitHub VFCs
uv run ousast pairs --slice github --json        # honesty dashboard as JSON
uv run ousast pairs --slice sast                 # OWASP Benchmark + Juliet Youden (TPR-FPR)
uv run ousast pairs --slice vibe-py --pointers   # nightly: pointer pairs via the local cache (network)
uv run python -m openultrasast.pair_gate         # CI: local pairs must all pass

Each case is two isolated trees (vuln file vs patched file, same relative path). pair_correct means the harness fired on the vuln side and stayed silent on the fix. Misses and fix-side leaks become miss/fp signals for ousast improve. The catalog and public dataset pointers live in benchmarks/pairs/.

5. Self-improve the ruleset from benchmark feedback

uv run ousast improve benchmarks/manifests/java-spring-boot-vulnerable.toml --dry-run  # preview
uv run ousast improve benchmarks/manifests/java-spring-boot-vulnerable.toml            # apply
# Accepted edits land in <target>/.openultrasast/calibration/rule_policy.json,
# which the next scan/benchmark of that target loads automatically.

6. Standard mode with the HarnessX agentic plane (OpenAI)

uv sync --extra harnessx
export OPENAI_API_KEY=sk-...
cat > openultrasast.toml <<'TOML'
[models]
hunter   = "gpt-4o"
verifier = "gpt-4o"
[harnessx]
provider        = "openai"
max_cost_usd    = 2.0
token_threshold = 120000
[fusion]
panel_model = "gpt-4o"   # two-panel adjudication on triggered findings
[hardening]
redact_secrets = true
max_findings   = 0
TOML
uv run ousast scan /path/to/code --mode standard --config openultrasast.toml
jq '.degradations' "$run/manifest.json"   # null = HarnessX ran; entries = it fell back
jq '.fusion'       "$run/manifest.json"   # per-finding dispositions

7. Drive it from an MCP client (OpenCode / IDE)

{ "command": "uv", "args": ["run", "ousast", "mcp"] }

Then: openultrasast.scan {path} → run_dir → openultrasast.findings {run_dir} → openultrasast.explain {run_dir, finding_id}. See the README "MCP server" section.
