Multiple checks used the pattern: count=$(echo "$diff" | grep -E 'pattern' 2>/dev/null | wc -l | tr -d ' ') Under 'set -o pipefail', when grep finds zero matches it returns exit 1, which propagates through the pipe. Under 'set -e', the containing script exits silently — no stderr, no stdout, exit code 1. The 'aggregate.sh skips invalid JSON' safety net (added earlier) masked this by producing a summary that omitted the failing checks. Fix: wrap each grep-in-pipe with { grep … || true; } so zero-match returns success. Affects: - check-deps-supply.sh (count_lines helper) - check-pr-size.sh (count_lines helper + mods_count) - check-telemetry.sh (client_files, test_files, new_decorators) - check-testing-depth.sh (new_modules) - check-deletion-hygiene.sh (hits) Impact: live orchestrate.sh runs now emit valid JSON for all 20 checks instead of 15/20. No FP regression (all fixes preserve semantics).

The check was counting string occurrences from the on-disk AST — global to the file — then anchoring the finding to the first occurrence's line number. When a PR (a) shifts line numbers by adding upstream code and (b) does not touch any of the actual repeated-string lines, PY-CON-01 fires for tech debt that pre-existed the PR. Fix: read $ADDED_LINES_FILE (already exported by orchestrate.sh) inside check_con_01. Filter each literal's occurrence list to lines actually in the PR's added set. Only fire when ${filtered} is non-empty AND total occurrences (across file, unchanged) still >= threshold. Anchor line becomes the first added-line occurrence. Backward-compat: if ADDED_LINES_FILE is unset (bats tests exercising the lib directly), fall back to the legacy full-file behavior. Two new regression tests pin both branches (untouched pre-existing repetition = no fire; at least one occurrence on added line = fires with correct anchor).

charset=UTF-8 Content-Transfer-Encoding: 8bit Discovered running the skill against 3 real PRs (py#209, py#161, jv#5): FP-L-01: breaking-detector no longer flags additive signature changes (adding an optional trailing arg). New _is_breaking_sig_change() with 6 unit-tested cases. Signature tuple extended to 6 elements (default counts). Was BLOCK_LOCKED — the most damaging FP. FP-M-01: detect-language.sh handles multi-module Maven (/src/main/java), not just root src/main/java. cloud-sdk-java is multi-module after the artifact-separation PR. FP-N-01: performance. hardcode/secrets/disclosure/concurrency/http-hygiene used a shell loop over every added line (80k forks on a 13k-line diff → timeout). Added awk pre-filter so only candidate lines reach the loop. check-hardcode on jv#5: 120s+ → 1.8s. FP-O-01: ignore_files / test-file skips cover /src/test/ (multi-module), so HC-* and BND-02 no longer fire on Java test fixtures. COM-01: tier BLOCK → FLAG. Commit-message convention violations flooded reviews (33 BLOCKs on py#161); squash-merge normalizes them anyway. pipefail hardening: check-versioning (version grep|head), check-docs (grep|sed|sort), check-license-spdx (find|head SIGPIPE) all wrapped so a zero-match no longer silently kills the script under set -e. check-docs / check-license-spdx: Java module detection + SPDX sampling now walk the multi-module tree. orchestrate: per-check timeout 60s → 180s (belt-and-suspenders on top of the perf fix). Validated: jv#5 now 0 invalid-JSON reports (was 9), 0 BLOCK, 3 real FLAGs.

Added gh_api() wrapper that injects --hostname $(detect_hostname); all 12 call sites use it. FP-Q-01: breaking-detector flagged deletions of symbols the PR never touched. When a PR branch is behind main, base..head surfaces files+symbols that MAIN added; the AST diff read those as PR deletions (47 false BREAKING details on py#161, all BLOCK_LOCKED). Two-layer fix: 1. files_changed() intersects with the PR's own changed files (from ADDED_LINES_FILE). 2. every deletion finding (api_removal, method/field/enum deletion) is gated on the removed symbol actually appearing on a '-' line of the PR diff (DIFF_FILE). No diff context → no gating (backward-compat). Validated: py#161 8 BLOCK → 6 (the 2 BREAKING FPs gone; 6 remaining are real TPs on a new module). jv#5 posts label+summary correctly now.

Now aggregate.sh stamps each finding with its .check and counts ONLY posted (retagged) findings per check. disclosure/pr-size that get shadowed show 0. Sum of table counts == total findings (asserted). 2. Non-anchored findings (PR_BODY, missing files/dirs, commit metadata, tests/ synthetic paths) no longer attempt a failed inline post. orchestrate splits: findings whose file:line is in ADDED_LINES_FILE post inline; the rest go into a 'Findings not tied to a specific code line' section of the summary, plus a reconciliation line ('N findings: X inline, Y listed above'). 3. Idempotency hardened: delete_prior_bot_artifacts loops up to 5×, re-listing until no bot comment remains — kills the duplicate-summary / repeated-comment accumulation caused by a single delete pass racing pagination. Regression tests: new .claude/tests/test_signals.bats (5 tests) pins the reconciliation invariant, shadow exclusion, PASS-check presence, and .check stamping.

Summary now lists EVERY finding (not just non-anchored). Anchored findings link to their inline comment via html_url; metadata findings show location. Previously an inline-only finding vanished from the Conversation tab — the table showed N but the summary listed fewer. Now the '### Findings (N)' section always matches the table total, and the reconciliation line closes. 2. post_summary_comment updates the existing summary in place (PATCH) instead of delete+recreate. Kills the duplicate-summary race under concurrent runs. delete_prior_bot_artifacts no longer removes the summary (only inline). 3. post_inline_comment now echoes the created comment html_url so the summary can deep-link to it.

Two-part fix: 1. Regex widened to 'diff --git a/([^ ]*/)?( tests?/|src/test/)' so an optional module-prefix is allowed before the test-folder segment. 2. grep runs on $DIFF_FILE directly instead of piping echo "$diff_content" — for 670 KB diffs the echo form truncates/diverges from the file, causing the match to silently fail regardless of the regex.

FP-P (SEC-07 — 17 false BLOCK_LOCKED): Test fixture PEM stubs in tests/ triggered BLOCK_LOCKED on every PR adding test coverage. Fix: skip SEC-07 when file path matches tests/ pattern. FP-Q (TD-10 — ~11 false BLOCKs): 'New module has no integration test' re-fired on PRs touching existing modules (agentgateway, adms) that have always lacked integration tests. Rule now only fires when src/<mod>/__init__.py appears with 'new file mode' in the diff. FP-N (HC-01 — ~4 false BLOCKs): *.example.com / *.example.org RFC 2606 subdomains in Pydantic model defaults. FP-O (HC-01 — ~5 false BLOCKs): URLs with <placeholder> tokens (e.g. <region>) in docstrings/configs. Checks raw content line before URL extractor truncates at '<'.
