Regex inventory stays the proposer. MAP attaches promote/demote/unadjudicated/coverage from intra-file taint (tree-sitter when a grammar parses, Python ast as last resort). Deep sandboxes promotions only, ordered by the existing heuristic ranker plus optional OpenRouter mechanism recall. The SAST pair slice scores overlay outcomes; the stage-1 detection gate and local pair gate stay inventory-only.

# Vuln vs fixed pair corpus
|
||
|
||
This corpus measures harness **efficiency**, not cheat-sheet recall.
|
||
|
||
The stage-1 smoke gate (`python -m openultrasast.gate`) scans one tree that
|
||
already contains the planted sinks. A pair eval instead scans **two isolated
|
||
trees**:
|
||
|
||
1. **vuln** — only the vulnerable file. The harness should fire (true positive).
|
||
2. **fixed** — only the patched file, same relative path. The harness should stay
|
||
silent on that CWE (true negative).
|
||
|
||
`pair_correct` = detected on vuln **and** silent on the fix. That is the signal
|
||
the improvement loop consumes (`miss` on the vuln side, `fp` on the fix side).
|
||
|
||
## Layout
|
||
|
||
| Path | Role |
|
||
| --- | --- |
|
||
| `catalog.toml` | Runnable offline pairs (local fixtures + vendored GitHub functions) |
|
||
| `datasets.toml` | Pointers to public VFC datasets — do not vendor the dumps |
|
||
| `datasets/cwe-bench-java-project_info.csv` | 120 vetted Java CVE buggy/fix commits |
|
||
| `github/` | Isolated function excerpts with provenance headers |
|
||
|
||
Pairs in this directory **must not** join `LANGUAGE_MANIFESTS`.
|
||
|
||
## Slices
|
||
|
||
- **local** — in-tree fixture counterparts (`app.py` vs `safe.py`, …). CI gate:
|
||
every local pair must pass (`python -m openultrasast.pair_gate`).
|
||
- **github** — real commit/function pairs (SVEN, CWE-Bench-Java, NVD patterns).
|
||
Measured, not a 90% smoke gate. Misses here are the honesty / evolve-the-harness
|
||
dashboard.
|
||
- **sast** — OWASP Benchmark Java/Python true-vs-false files and Juliet
|
||
bad-vs-good sinks (`benchmarks/pairs/sast/`). Score is Youden (TPR − FPR).
|
||
Honesty dashboard, not a CI fail.
|
||
|
||
## Commands
|
||
|
||
```bash
|
||
uv run ousast pairs
|
||
uv run ousast pairs --slice github --json
|
||
uv run python -m openultrasast.pair_gate
|
||
```
|
||
|
||
## Growing the corpus
|
||
|
||
Prefer function-level before/after from a reviewed source (SVEN jsonl, a
|
||
CWE-Bench-Java `fix_info.csv` row, a GHSA with a tiny patch). Isolate the
|
||
changed function into `vuln` / `fixed` files with the same `relpath`. Leave
|
||
whole-repo clones to `--fetch` later; CI stays offline.
