Closes the harness's feature set per PROMPT.md modes 2 (Diff Review)
and Phase 5 (Memory). Rules subcommand still pending (it needs
operator-authored .review-rules.md content first; documented as
Phase E follow-up).
internal/memory/ — append-only writer:
- AppendKnownRisks: one JSONL line per confirmed finding per run.
O_APPEND only; never O_TRUNC. Empty findings list is a no-op
(doesn't even create the file — keeps clean runs from polluting
.memory/).
- AppendRunHistory: one JSONL line per run. Run summary stats +
receipts hash for cross-link.
- WriteProjectProfile: the ONLY non-versioned memory file; snapshot
semantics, overwrites are explicit + documented.
- 4 unit tests including TestAppendKnownRisks_NeverTruncates which
is the audit's "no silent overwrite" gate — write twice, assert
both writes' content survives.
Pipeline phase 5 wires it. Confirmed findings only — suspected
findings might still be wrong, keeping .memory/ authoritative.
Disabled if review-profile.memory.enabled = false.
internal/git/git.go — ChangedFiles helper:
- Probes unstaged + staged + branch diff against main/master.
- Dedup'd, stable order. Empty result on clean tree.
- Graceful failure: returns error if git binary missing or target
isn't a git repo.
cli/repo.go — Diff subcommand:
- `review-harness diff <path>` runs the same pipeline as scrum but
scoped to changed files only. Pipeline.Inputs gains DiffOnlyFiles
filter applied post-Walk.
- Empty diff (clean tree, no commits ahead of base) → exit 0 with
message; doesn't generate empty reports.
- LLM toggleable via --enable-llm same as scrum.
scanner/walk.go: added .memory to SkipDirs (universal — harness's
own audit trail, scanning it surfaces planted-secret evidence as
new findings — same class as B5 self-skip).
.gitignore tightened: /.memory/ → **/.memory/ to keep test-fixture
.memory dirs from leaking into version control (same fix as
reports/latest pattern).
Verified end-to-end:
- 4 memory unit tests PASS
- Append-only proven: insecure-repo run 1 → 16 known-risks lines;
run 2 → 44 lines (16 + 28 from new run); run-history grew 1 → 2.
- Diff subcommand against this repo (5 uncommitted Phase E files
staged) → exit 0, all reports produced, scoped to those 5 files
only (0 findings on the diff-scoped scan vs 129 on full repo —
changed files don't contain analyzer-flaggable patterns).
Phase A through E shipped today. Rules subcommand + tests for
internal/{config,scanner,git,llm,reporters,pipeline} remain.

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.
