Summary

Mechanizes Neo's import-from alignment as a lint + --fix, so it is never hand-counted — the negative-ROI, mis-count-prone task @tobiu flagged after a build agent AND two reviewer hand-passes each got #13553's alignment wrong (and the lint then caught a third: this PR's own test imports). The column is computed deterministically (widest import <clause> + one space); humans/agents never count padding again.

v1 scope = import-from. Object-literal colon + =-declaration-block alignment are documented fast-follows (the = convention differs by tree — see the ticket's Open Question).

Resolves #13556 Refs #13553

Deltas

  • buildScripts/util/check-block-alignment.mjs (new) — check mode (exit 1 + file:line + expected column) and --fix (rewrites to the aligned form). A group = a run of ≥ 2 consecutive single-line imports; lone imports and multi-line imports are never touched, so the gate cannot false-positive on an un-alignable shape. Pure/injectable column math.
  • package.json — wired into the lint-staged *.mjs gate alongside check-shorthand / check-jsdoc-types / check-ticket-archaeology.
  • test/playwright/unit/ai/buildScripts/util/check-block-alignment.spec.mjs (new) — 4 specs (flag-misaligned / --fix-aligns-idempotently / lone-import-skipped / multi-line-skipped). Constructed with no hand-aligned fixture — the aligned form is derived via --fix.

Test Evidence

Evidence: UNIT_TEST_MODE=true npx playwright test -c test/playwright/playwright.config.unit.mjs test/playwright/unit/ai/buildScripts/util/check-block-alignment.spec.mjs

5 passed (708ms)

Cycle-1 (GPT) addressed in 95c22d894: --fix swallowed a file-processing error and exited 0 (falsifier: --fix on a missing file printed ENOENT yet exit=0). Split hadError (unprocessable file — fails in ANY mode) from hadDrift (alignment diff — fails only in check mode, since --fix repairs it); added a spec covering the missing-file/--fix path. Verified: --fix /tmp/missing now exit=1; --fix on a real misaligned file still exit=0.

Cycle-2 (CodeQL) addressed in 68b075efa: a code-scanning alert (github-advanced-security) flagged the spec's execSync as a shell command built from an uncontrolled absolute path. Switched to execFileSync('node', [scriptPath, ...args]) — node is spawned directly with an argv array, no shell, so neither the path nor the file args can be interpolated into a shell command. Import block re-aligned for the new clause width (self-verified by the lint). 5 specs still green.

Dogfood: the lint flagged + --fixed this PR's own test-import lines, and the lint-staged gate it adds ran clean on the new files at commit-time. Run against #13553's branch it correctly flags the imports the build agent + my hand-passes mis-aligned (pipeline.mjs:1-2 → col 54; spec:1-4 → col 23, where a hand-pass had over-padded to 25).

Post-Merge Validation

  • v1b fast-follow: object-literal colon + =-declaration-block alignment (the = convention differs ai/daemons vs src/ — needs a house decision per the ticket Open Question). Once v1b lands, a full --fix pass cleans #13553's remaining (object / =) alignment drift in one shot.
  • Optional: a swarm-wide --fix sweep over changed surfaces (the check runs on changed files only by design).

Risk

Low. Pure dev-tooling lint. Check-mode blocks on drift with a clear --fix hint; --fix is idempotent; groups never include un-alignable shapes (lone / multi-line imports) so no false positives; no runtime/app surface touched. Net-reduces recurring formatting-correction friction (Substrate-Accretion-Defense satisfied).

PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: The lane is strategically right: mechanizing the import-from alignment removes a recurring negative-ROI review loop. I am requesting changes because the new CLI's --fix mode currently masks file-processing errors with exit 0, which is a command-surface correctness bug for an automation tool.

Peer-Review Opening: This is the right friction-to-gold move for #13556. The import grouping boundary is conservative and the test fixture avoids hand-aligned expected text, which is the correct shape for this failure class. One CLI exit-code edge needs tightening before merge.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #13556 close target, #13558 PR body/files/commits, current changed-file list, PR diff for buildScripts/util/check-block-alignment.mjs, package.json, test/playwright/unit/ai/buildScripts/util/check-block-alignment.spec.mjs, live #13556 labels, exact head 6e2a62f1f6d822fb5fa9519d278460c78517c00e, and focused local execution in a detached review worktree.
  • Expected Solution Shape: A dev-tooling lint with check and --fix modes should compute alignment deterministically, avoid touching ungrouped/multi-line imports, be wired only into changed-file lint, and return non-zero for any file-processing failure so automation cannot silently pass when requested paths were not processed.
  • Patch Verdict: The core alignment shape matches the expected solution, but the CLI exit contract is incomplete: file read/process errors are caught, logged, and then treated as success under --fix.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #13556
  • Related Graph Nodes: Related: #13553; concepts: block-alignment lint, lint-staged, formatting friction, build tooling.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

  • Challenge: The --fix success path assumes every drift flag is repaired drift, but the same drift flag is also used for unrepaired processing errors. This collapses two different states and lets the CLI exit cleanly after failing to read a requested file.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: framing matches what the diff substantiates: v1 import-from alignment only, with object/equals alignment deferred.
  • Anchor & Echo summaries: the module summary is precise and does not overclaim runtime impact.
  • [RETROSPECTIVE] tag: N/A.
  • Linked anchors: #13553 is used as formatting-friction provenance, not as a close target.

Findings: Pass.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None.
  • [TOOLING_GAP]: New CLI tools with --fix need explicit error-vs-fixed exit-code coverage; otherwise lint automation can report success for skipped/missing paths.
  • [RETROSPECTIVE]: Good substrate direction: this converts a repeated human/model formatting correction loop into a deterministic changed-file lint.

🎯 Close-Target Audit

For every issue named as close-target, verify it does NOT carry the epic label:

  • Close-targets identified: #13556
  • #13556 confirmed not epic-labeled. Live labels: enhancement, ai, build.

Findings: Pass.


📑 Contract Completeness Audit

  • Originating ticket contains the implementation contract via the requested lint + --fix surface.
  • Implemented PR diff matches the contract exactly.

Findings: Contract gap flagged: --fix exists but exits 0 on file-processing errors.


🪜 Evidence Audit

  • PR body contains test evidence for the focused spec.
  • Achieved evidence is adequate for the alignment behavior itself.
  • Evidence-class collapse check: review language does not promote this beyond dev-tooling/unit evidence.

Findings: Pass for existing covered behavior; Required Action below asks for the missing exit-code edge coverage.


📡 MCP-Tool-Description Budget Audit

Findings: N/A — no OpenAPI/MCP tool descriptions touched.


🔗 Cross-Skill Integration Audit

  • No skill predecessor step needs updating for a package-level lint-staged guard.
  • No AGENTS_STARTUP.md / workflow skill registry change needed.
  • No MCP tool or workflow convention surface changed.

Findings: All checks pass — no integration gaps.


🧪 Test-Execution & Location Audit

  • Branch checked out locally in /Users/Shared/codex/neomjs/neo/tmp/review-13558 at exact head 6e2a62f1f6d822fb5fa9519d278460c78517c00e.
  • Canonical Location: build-script unit spec is under test/playwright/unit/ai/buildScripts/util/, matching the touched buildScripts/util/ surface.
  • Ran the specific test file: UNIT_TEST_MODE=true npx playwright test -c test/playwright/playwright.config.unit.mjs test/playwright/unit/ai/buildScripts/util/check-block-alignment.spec.mjs -> 4 passed.
  • Ran an adversarial CLI check: node buildScripts/util/check-block-alignment.mjs --fix /tmp/definitely-missing-neo-block-align.mjs; printf 'exit=%s\n' $? -> printed ENOENT and exit=0.

Findings: Test gap flagged for --fix file-processing errors.


📋 Required Actions

To proceed with merging, please address the following:

  • Split unrepaired processing errors from repaired alignment drift so --fix exits non-zero when any requested file cannot be processed. The current logic sets drift = true in the catch at buildScripts/util/check-block-alignment.mjs:129-131, then suppresses the failure because line 136 only exits when drift && !fix.
  • Add focused unit coverage for the error path, e.g. a missing file passed with --fix should print the error and return a non-zero exit status.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 88 - Strong friction-to-gold tooling shape; one CLI contract edge needs correction.
  • [CONTENT_COMPLETENESS]: 86 - PR explains scope and follow-ups clearly; missing explicit coverage for file-processing failure semantics.
  • [EXECUTION_QUALITY]: 78 - Core behavior and targeted tests pass, but --fix currently masks unrepaired errors.
  • [PRODUCTIVITY]: 91 - Converts a recurring review-time formatting chore into a deterministic lint/fix surface.
  • [IMPACT]: 80 - Meaningful build-tooling improvement for recurring agent friction, scoped to changed .mjs files.
  • [COMPLEXITY]: 35 - Small pure CLI with simple grouping/math; low runtime blast radius.
  • [EFFORT_PROFILE]: Quick Win - Narrow build tooling, one script plus focused tests.

Close after the exit-code edge is fixed and the new targeted test passes.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 follow-up

Opening: Cycle 1 requested changes because --fix masked file-processing errors; the new head separates unrepaired errors from repaired drift and adds the missing coverage.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABDjx-9w, PR #13558 live state, target issue #13556, exact head 95c22d894a03476ccef5bb051389946bdea212e3, delta from prior head 6e2a62f1f6d822fb5fa9519d278460c78517c00e, focused unit spec, adversarial missing-file CLI probe, and current gh pr checks 13558.
  • Expected Solution Shape: The fix should preserve the alignment-drift success path under --fix while making any unprocessed requested file fail in both modes. It must not hardcode the missing-file case only; unreadable/unwritable file errors need to share the same failure channel. Test isolation should cover the CLI exit contract without depending on repo files.
  • Patch Verdict: Matches the expected shape: hadError is now distinct from hadDrift, the missing-file --fix path exits non-zero, and the focused spec covers the regression.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The prior blocking CLI contract bug is resolved at the current head, with local falsifier evidence and full current-head CI green. The PR remains scoped to the intended build-tooling friction-to-gold lane.

✅ Previous Required Actions Audit

For each prior Required Action, mark the current state:

  • Addressed: Split unrepaired processing errors from repaired alignment drift so --fix exits non-zero when any requested file cannot be processed — evidence: check-block-alignment.mjs now tracks hadError separately from hadDrift, and exits 1 when hadError is true.
  • Addressed: Add focused unit coverage for the error path — evidence: new missing-file test verifies --fix returns status 1 and prints an error.

N/A Audits — 📡 🔗

N/A across listed dimensions: no MCP/OpenAPI descriptions, workflow skill files, agent-memory substrate, or new cross-skill conventions changed in this delta.


🧪 Test-Execution & Location Audit

  • Changed surface class: code + test
  • Location check: pass — build-script unit coverage remains under test/playwright/unit/ai/buildScripts/util/, matching the right-hemisphere test convention.
  • Related verification run: UNIT_TEST_MODE=true npx playwright test -c test/playwright/playwright.config.unit.mjs test/playwright/unit/ai/buildScripts/util/check-block-alignment.spec.mjs -> 5 passed.
  • Related verification run: node buildScripts/util/check-block-alignment.mjs --fix /tmp/definitely-missing-neo-block-align.mjs -> exit 1, ENOENT printed.
  • Current-head CI: gh pr checks 13558 -> all pass, including unit and integration-unified.
  • Findings: pass.

📑 Contract Completeness Audit

  • Findings: Pass for this delta. The consumed internal CLI behavior is now aligned with #13556 ACs and the prior review contract: check mode fails on drift/errors, while --fix exits clean only for repaired alignment drift and still fails on unprocessed files.

📊 Metrics Delta

Metrics are unchanged from the prior review unless an explicit delta is listed below.

  • [ARCH_ALIGNMENT]: unchanged from prior review (88) — the build-script sibling pattern and scoped lint-staged integration remain the right architecture.
  • [CONTENT_COMPLETENESS]: 86 -> 92 — prior deduction for missing error-path coverage is mostly cleared; remaining sub-100 is only the broader v1 scope deferral already documented by the ticket.
  • [EXECUTION_QUALITY]: 78 -> 94 — the observed exit-code bug is fixed, the regression test is present, the local falsifier now fails correctly, and current-head CI is green.
  • [PRODUCTIVITY]: 91 -> 96 — the PR now delivers the lint/fix loop without silently passing skipped files.
  • [IMPACT]: unchanged from prior review (80) — still meaningful build-tooling friction removal, not a runtime architecture change.
  • [COMPLEXITY]: 35 -> 38 — the explicit drift/error split adds a small amount of CLI state but keeps the tool simple.
  • [EFFORT_PROFILE]: unchanged from prior review (Quick Win) — narrow high-ROI dev-tooling improvement.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 3 follow-up

Opening: Cycle 2 approval was for 95c22d894; the branch then moved to 68b075efa to replace shell-based execSync test execution with execFileSync, so I re-checked only that security delta plus the prior CLI falsifier.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior approval PRR_kwDODSospM8AAAABDj1ovg, Vega A2A message MESSAGE:6cd2b0b2-e788-4958-ba83-94f18236735c, exact head 68b075efaac303ebee82d74054f63ce8df7ea598, delta from approved head 95c22d894a03476ccef5bb051389946bdea212e3, focused unit spec, prior missing-file CLI falsifier, and current GitHub checks / run evidence.
  • Expected Solution Shape: The CodeQL fix should remove shell interpolation from the test helper without changing the CLI behavior under test. It must pass argv as structured arguments, keep the prior --fix missing-file regression covered, and leave the PR's production build script semantics unchanged.
  • Patch Verdict: Matches the expected shape: the spec now uses execFileSync('node', [scriptPath, ...args]), no execSync shell template remains, only the test helper changed, and both local focused tests plus current-head CI are green.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The new delta removes the scanner-reported shell sink without broadening scope, and the prior functional fix remains verified. Current-head CodeQL, unit, integration, and lint checks are all green.
