From 42e6897cf78d18054cbb3eeaad1bb517addc909a Mon Sep 17 00:00:00 2001 From: Aditya <82406617+adigo-pro@users.noreply.github.com> Date: Tue, 4 Aug 2026 20:53:30 -0500 Subject: [PATCH 01/10] fix(redact): close five redaction-correctness holes at the boundary MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Audit-verified gaps where the documented "nothing downstream holds a raw secret" / "no false redaction of ordinary code" contracts didn't hold: - PEM private keys survived redact() inside `git diff` text — every diff line carries a +/-/space marker, so the END line reads `\n+-----END …` and the suffix never matched. Tolerate one marker char after the newline. This is the PRIMARY capture path (observer/gitwatch.py diffs + commits). - The assignment pattern matched key/secret/token/password as a SUBSTRING, so `tokenizer = "bert-base-uncased"` / `monkey` / `keywords` redacted to a «REDACTED» marker — which the critic is taught IS a confirmed secret, manufacturing false findings. Require the keyword to be a delimited token (start/_/-/digit or camelCase boundary); keep API_KEY/db_password/apiKey. - PASS `reason` and `malformed` raw reply in parse_reply took the same tool-equipped-model path as issue/rationale but skipped sanitize(). - verify._classify's inconclusive diag note stored raw executed-script output (verified/refuted notes were already sanitized). - Distilled knowledge facts were never redacted, though SECURITY.md:29 claims they are — and they re-inject into every judgment prompt. Tests: PEM-in-diff, camelCase names redact, incidental-substring names do not, fact credential-shape + control-sequence stripping.

Atomic write + tolerant load_cases. - heuristics-history archive was written non-atomically; an empty/torn archive then IndexError'd maybe_rollback on restored[0].

Adds write_text_atomic to core.store (fsync + tmp-cleanup, shared by the archive writer); write_json_atomic gains the same fsync + orphan-tmp cleanup.

They are now never age-pruned — bounded by count (RESERVED_KEEP newest) instead. - Raised the suggestion-id retention (LEDGER_TTL_SECONDS 600 -> 3600) above the reflector's UNDELIVERED_AFTER_S=900 grading horizon + poll slack: a delivered mark pruned before the reflector grades made a genuinely-delivered (possibly accepted) finding grade "undelivered" and drop out of the acceptance metric. Delivery *freshness* is unaffected (governed by logic._age_ok on the row ts, not the ledger). - peer_hook.py imported core/critic modules at module scope, BEFORE main()'s fail-open guard. A transient syntax/import error in the critic chain (this repo's own files, edited live by the agent whose tool calls fire the hook) then tracebacked + exited 1 on every event. Wrap the project imports in a fail-open try. main() now catches BaseException so Ctrl-C during the gate wait also exits 0. - _describe hard-indexed s['file']/s['issue']; a row that passes _pending but lacks them (a hand-edited/foreign row) KeyError'd, and fail-open then suppressed every co-pending finding for the row's TTL. Use .get with fallbacks — _pending already tolerates bad data, so this sink must too.

charset=UTF-8 Content-Transfer-Encoding: 8bit - persona.md's TASK: VERIFY still taught the pre-script-redesign protocol ("write a script and RUN it, reply with EXACTLY one line CONFIRMED/ FALSE-ALARM/INCONCLUSIVE"). verify.py parses only a script that PRINTS CONFIRMED/REFUTED and exits 0; a model obeying the persona emitted a bare status line that executed as Python -> SyntaxError -> inconclusive, silently withholding true findings. Rewrote the section to the actual contract. - Whole test-file deletion was invisible to test-weakening screening: removed_lines_by_file only rebound path on `+++ b/`, so a deleted file's `+++ /dev/null` left its removed lines attributed to the previous file (or dropped). Track `--- a/` and attribute `/dev/null` deletions to it; reset path on non-b/ headers in both diff parsers. - `async def test_` never counted as a test (removed async tests escaped the weakened verdict): `_TEST_DEF_RE` now allows an optional `async `. - SafeLoader exemption scanned only to the first `)`, so `yaml.load(f.read(), Loader=yaml.SafeLoader)` false-flagged CWE-502; scan the whole line. - `_STR_BUILD_RE`'s `f["\']` matched a literal `f` before a closing quote inside a parameterized query (`'off'`), false-flagging SQL injection; anchor the f-string prefix. - _execute_probe ignored the probe's exit code and let DIVERGES beat CONSISTENT — a probe that printed DIVERGES then crashed (or printed both) minted a finding. Require returncode 0 and treat both-markers as error, mirroring verify._classify (this is the finding-CREATING path).

Now: require file/issue to be non-empty strings (else malformed-PASS), normalize severity into {low,medium,high} (critical->high), and drop a non-int line to None. - A model transport failure (provider outage) that survived ask_with_retry wrote an ERROR record and committed the offset, permanently skipping code written during even a brief outage with no way to replay it. judge_batch now raises on a primary ERROR verdict so the scheduler REQUEUES the batch and retries on a later beat (bounded by MAX_BATCH_RETRIES). Malformed replies (verdict PASS) and prober errors are unaffected. - The "done" review request advanced review_offset unconditionally, so a request landing while the worker was busy (the common case at Stop) was consumed with no review dispatched — losing the session receipt entirely for a one-shot session.

harden setup/session; rescore safety MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Measurement + robustness fixes to the A/B/training harness: - report()'s mean hidden-test pass rate DROPPED crashed trials (total==0) instead of scoring them 0 — so whichever arm crashed more reported an inflated rate, and the dependency-hallucination failure the 'closest-match' task engineers on purpose couldn't lower the mean. Crashed trials now score 0 and the per-arm summary reports the crash count. - run_session / training.run_task now catch TimeoutExpired/OSError: a hung session is a failed, retryable attempt — one hang no longer aborts a multi-hour paid run. Each trial in main() is wrapped so a setup/trial failure records an error row (crashed hidden / UNSAFE) and continues. - Setup git commands (clone/fetch/checkout/init/add/commit) were unchecked: a failed clone still spent a full session on a garbage workspace, and the --repo-url sha pin was unverified. Added _sh_checked + a `git rev-parse HEAD == sha` assertion; the seed commit pins identity + disables signing so it succeeds deterministically (previously it silently failed on CI with no git identity). - training.run_task inherited the maintainer's global ~/.claude settings — the exact contamination the A/B harness guards against — since it omitted `--setting-sources project,local`. Added it (training data drives harvested cases + rewrites). - rescore silently skipped the safety tier while claiming "the current scorer"; it now re-runs each safety task's adversarial exploit and reports how many rows were carried over unrescored.

Depend on the newest event's stable seq instead. - readNdjsonTail ignored readSync's byte count over an allocUnsafe buffer: if the file shrank between stat and read, uninitialized memory was decoded and parsed. Honor the returned length. - Removed lucide-react — a dependency no source file imports (every icon is inline SVG). Lockfile updated.

Every adversarial script now runs a happy-path guard first (function exists + does its job on legit input) → UNSAFE on absence/breakage, uniformly. --selftest still shows all five discriminating good vs bad. - Reusing --out reused trial dirs still holding a prior session's committed work (the next agent started with the task pre-solved) and appended duplicate rows to results.ndjsonl. seed_repo/clone_repo now recreate the trial dir fresh, and main() refuses a --out whose results.ndjsonl is non-empty (pointing at rescore instead).

charset=UTF-8 Content-Transfer-Encoding: 8bit Two load-bearing invariants the audit flagged as entirely untested: - "A finding the critic's own repro REFUTED is never delivered" — the product thesis — had zero tests (the string "refuted" didn't appear in test_hooks.py). Added coverage on both the context (PostToolUse) and block (Stop) channels, plus a sanity check that a verified finding still delivers. - verify.py's note/repro redaction boundary had no secret-shaped test; a regression removing the sanitize() would have been invisible. Added a CONFIRMED-with-credential test (note + repro) and an inconclusive-diag test.
