Code Review
This pull request introduces an automated post-conflict-resolution integrity check to detect duplicate top-level declarations introduced during automated rebases, integrating it into the rebase workflow to post advisory warnings. Feedback focuses on optimizing the symbol comparison logic to run in a single awk pipeline to avoid process-spawning overhead, correcting a potential set -e issue with short-circuit assignments, and utilizing $BATS_TEST_TMPDIR in BATS tests for cleaner temporary file management.

test to use resolved_corrupted.sh and pass two nonexistent parent paths, then
assert the output reports fn:run_writer while retaining a successful status.

Summary
Adds a post-conflict-resolution integrity check (#1482): a new pure awk-based library (scripts/lib/conflict-integrity.sh) detects duplicate top-level function/variable declarations introduced by an automated conflict resolution, wired into the rebase intent of dev-lead-fix-reviews.sh as an advisory-only, idempotent PR warning. Comprehensive bats coverage with fixtures replicating the #1449 corruption. The PR also repairs dev-lead-fix-reviews.sh itself, which had been corrupted on main by the org-sync commit 5b65dab (+1,168 duplicate lines; functions declared up to 5×) — exactly the corruption class this feature detects.
Linked issue analysis
Closes #1482. Substantively addressed for this repo: AC #1 (duplicate top-level declarations not present in both parents — single-pass awk, parent-aware to avoid false positives), AC #2 (runs on the conflict-resolution path itself, scanning the worktree so uncommitted resolutions are covered), AC #4 (advisory-only; || true guarantees a detector fault never fails a real resolution), AC #6 (pre-existing duplicates and large legitimate merges not flagged — fixture-tested). The auto-rebase update-branch path is a thin caller stub here; that half lives org-side. The repo owner's steering review replayed both historical #1449/#1485 corruption events through new_duplicate_symbols and confirmed detection against ground truth.
Findings
Independently verified during this review:
- De-duplication repair is genuine and safe. Compared main (2,523 lines, 10 functions duplicated 2–5×) against head (1,355 lines, 24 unique functions): every surviving definition is byte-identical to main's effective (last-wins) copy, except one noted below. The corruption source was sync commit
5b65dab, so no legitimate trunk changes are reverted. - Minor (non-blocking):
has_reviews_rate_limited_markerkeeps the older style that interpolates${pattern}into the jq program; the corrupting sync had a marginally saferjq --argcopy. All pattern components (PR number, SHA, intent) are internally generated, so there is no practical injection surface; worst-case malformation degrades to the|| echo 0fallback (no dedup). Worth re-applying the--argform in a follow-up. - Both unresolved review threads are substantively fixed at head (verified in code): gemini's O(N)-subshell +
set -econcern → single-pipeline awk with inline ternary; codeant's uncommitted-worktree gap →git diff "$pre_ref"with no second ref. Both are bot-initiated threads the agent cannot dismiss; maintainer replies document the fixes. - shellcheck clean on both the new library and the modified script (info-level SC2016/SC1091 only).
- Secret scan:
run_secret_scanningMCP tool unavailable in this environment; gitleaks CI check passed. No secrets, credentials, or workflow files touched.
CI status
All substantive checks green at a8efb181840a8f9cdff351159c91e6415b72d888: shellcheck, bats, unit-tests, validate-fixtures, CodeQL (actions + python), gitleaks, SonarCloud quality gate, agent-shield, actionlint, and all compliance/stub-freeze guards. The few CANCELLED/SKIPPED rollup entries are superseded orchestration runs (dev-lead dispatch/ci-relay, review) that each have a later SUCCESS run of the same check.

using the pattern as a jq argument and `contains`, and update the surrounding

Review mode: triage-approved (single reviewer)
Summary
Implements #1482's post-conflict-resolution integrity check: a pure, unit-tested detector library (scripts/lib/conflict-integrity.sh) for duplicate top-level shell declarations, wired advisory-only into the rebase intent of dev-lead-fix-reviews.sh, plus de-duplication of dev-lead-fix-reviews.sh itself, which on main carries exactly the corruption class this PR detects (functions defined up to 5x). Only change since the prior approved review (a8efb18) is registering the new bats test in lint.yml.
Linked issue analysis
Closes #1482 — all acceptance criteria are substantively met:
- AC #1/#6:
new_duplicate_symbolsflags only symbols whose declaration count exceeds both parents (base ref + pre-resolution tip), so pre-existing duplicates and legitimate large merges are not flagged. Covered by dedicated bats tests. - AC #2: check runs inside the rebase intent itself, immediately after
build_and_run, withPRE_RESOLVE_SHAcaptured before the resolution — not dependent on downstream tests. - AC #3/#4: advisory PR comment names file + symbols + counts, idempotent via marker,
|| trueguarantees it never blocks or fails the resolution. - AC #5: regression fixtures mirror the #1449 corruption (run_writer/parse_reset_time/extract_verdict_json doubled); the maintainer's steering review additionally replayed both real historical corruption events through the detector with a complete true-positive set and clean controls.
Test registration in lint.yml (the only delta since the last approval) closes the loop on CI enforcement.
Findings
Verified independently:
- main's
dev-lead-fix-reviews.sh(2523 lines) had 10 functions defined 2–5x; head (1355 lines) defines every function exactly once. I extracted each retained function body and confirmed it matches the last definition on main (the one bash actually used), so the de-dup preserves active behavior. - Ran the PR's own detector against the de-duplicated head script: no duplicate symbols remain (only the pre-existing, benign
PROMPTS_DIRreassignment). - Only top-level flow removed is the triplicated checkout/hold-auto-merge block; one copy is retained.
Minor (non-blocking):
has_reviews_rate_limited_marker— the retained copy uses the older shell-interpolated jq pattern (test(\"${pattern}\")) whereas main's active (last) copy used the hardened--argform. Functionally equivalent for the values in play (PR number, SHA, fixed intent names contain no quotes/backslashes), but worth restoring the--argform in a follow-up._count_of()in the new lib is dead code (already noted as non-blocking in the maintainer's steering review).
Secret scan: MCP secret-scanning tool not available in this run; gitleaks CI check is green. No secrets, credentials, or auth-surface changes in the diff; fixtures are inert shell stubs.
CI status
All required checks green on 83f667a: shellcheck, ShellCheck, bats, unit, unit-tests, Lint, actionlint, CodeQL (actions+python), SonarCloud (quality gate passed, 0 new issues), gitleaks, agent-shield, CodeRabbit (approved), Graphite AI, plus all org guard/validation checks. Cancelled/skipped entries are superseded earlier runs. 0 unresolved review threads; latest CodeRabbit state APPROVED; maintainer steering review reports no blocking findings.
