Implements PROMPT.md / docs/REVIEW_PIPELINE.md Phase 3:
"AI may suggest. Code validates."
internal/validators/validate.go — 3 hard checks per the
"Reject A Finding If" list:
- file does not exist (with path-traversal guard against the LLM
hallucinating ../../../etc/passwd)
- cited evidence does not appear in the file (verbatim or
trim-line-by-line — models often re-indent quotes when quoting code)
- line hint exceeds file line count
3 soft checks documented as open (claim semantics, suggested-fix
relevance, invented tests/commands — all need another LLM pass).
internal/validators/validate_test.go — 9 tests including:
- TestValidate_RejectsNonexistentFile (gate D1)
- TestValidate_RejectsEvidenceNotInFile
- TestValidate_RejectsLineHintBeyondFile
- TestValidate_AcceptsRealFinding
- TestValidate_AcceptsEvidenceWithDifferentLeadingWhitespace
- TestValidate_RejectsEmptyEvidence
- TestValidate_PassesThroughStaticFindings
- TestValidate_RejectsPathEscapingRepo (path-traversal protection)
- TestValidate_AcceptsRelativeRepoPath (the regression — see below)
Pipeline phase 3 wired between LLM review (Phase C) and report gen
(Phase 4). validated-findings.json contains the confirmed set;
rejected-findings.json contains rejects with per-finding reason +
detail. Receipt phase entry honest about output files + status.
=== Bug J caught ===
First Phase D run rejected EVERY real LLM finding as file_not_found
because the path-traversal check compared a relative joined path
(`tests/fixtures/insecure-repo/src/handler.go`) against an absolute
repoAbs (`/home/profit/share/.../insecure-repo`), so HasPrefix
always returned false. Both sides now resolved via filepath.Abs
before comparison. Regression test
TestValidate_AcceptsRelativeRepoPath locks this in — runs the
validator against a relative repo path AND a relative chdir, the
exact shape that hit the bug.
J's framing was honest: "I don't know what the problem is, but you
know what we're trying to accomplish." The fix-it-yourself signal
let me trace through the rejection details + see the smoking gun
in the detail string ("escapes repo root"). Without that prompt the
9 false rejections might have looked like real LLM bugs.
=== 2 close-out fixes ===
1. .gitignore: changed `/reports/latest/` → `**/reports/latest/`
(and same for `run-*`). Phase C committed 22 generated files
from `tests/fixtures/*/reports/latest/` because the original
pattern was anchored at the harness root only. Existing tracked
files removed via git rm --cached; new pattern keeps fixture
reports out of version control going forward.
2. pipeline.cleanOutputDir: pipeline now deletes the bounded list
of known per-run files at the start of each run. Before this,
a prior run's rejected-findings.json could linger when the
current run had no rejections — confused J during the bug hunt
above. cleanOutputDir is bounded (deletes only files we emit)
so operator-owned adjacent files stay.
Verified end-to-end: insecure-repo + --enable-llm → 25 confirmed
findings (16 static + 9 LLM), 0 rejected.
