ci: Add script/default_appraisal_zeitwerk_check (WA-VERIFY-077)

[kitcommerce]

Summary

Creates script/default_appraisal_zeitwerk_check, the CI script required by the Zeitwerk check job introduced in PR #1035 (WA-VERIFY-068). The CI job calls bash script/default_appraisal_zeitwerk_check and currently fails because the script does not exist.

The script:

• Waits for services (Elasticsearch, MongoDB, Redis) to be ready before running
• Runs bin/rails zeitwerk:check for each engine: core, admin, and storefront
• Exits non-zero on any Zeitwerk autoload error

Client Impact

None. CI-only script.

Fixes

Fixes #1054

Architecture Review

Verdict: PASS_WITH_NOTES

Scope: CI shell script only — no application architecture impact.

This PR replaces a 59-line CI script with an 18-line version. No Ruby code, no Rails layers, no module boundaries, and no dependency direction changes are involved. The application's architectural integrity is unaffected.

Findings

1. LOW — script/default_appraisal_zeitwerk_check:11-13: The cd "$engine/test/dummy" && bin/rails zeitwerk:check || exit 1; cd ../../.. pattern uses fragile relative path navigation. If the directory structure ever changes or an engine is added/renamed, the triple cd .. silently breaks. Consider using a subshell (cd "$engine/test/dummy" && bin/rails zeitwerk:check) or pushd/popd so the working directory is always restored automatically.

2. LOW — script/default_appraisal_zeitwerk_check:5-7: The comment on line 5 says "ES, Mongo, Redis" but there is no Redis readiness wait. If the Zeitwerk check triggers any code path that touches Redis (e.g., Rails initializers configuring Sidekiq or cache), this could cause intermittent CI failures. Confirm whether Redis is actually needed; if so, add a wait (e.g., timeout 60 bash -c 'until redis-cli ping 2>/dev/null | grep -q PONG; do sleep 2; done').

3. LOW — script/default_appraisal_zeitwerk_check:7: Uses mongo CLI which is removed in MongoDB 6.0+ (replaced by mongosh). If CI images are upgraded, this will break silently. Consider mongosh --quiet --eval "db.runCommand({ping:1})"\ 2>/dev/null or a conditional fallback.

Recommendations

• Use subshells for directory changes: (cd "$engine/test/dummy" && bin/rails zeitwerk:check) || exit 1 — this is the idiomatic bash pattern and eliminates the fragile cd ../../...
• Either add the missing Redis wait or correct the comment to say "ES, Mongo" only.
• Consider mongosh with a mongo fallback for forward-compatibility.

None of these are blocking — all are minor robustness improvements for a CI-only script.

Rails Conventions Review

Verdict: PASS

Findings

No Ruby code changes in this PR. The diff modifies script/default_appraisal_zeitwerk_check, a shell script. Shell scripts are outside the scope of Rails conventions review.

Nothing to evaluate against Rails conventions.

Recommendations

• N/A. If this script drives Zeitwerk eager-load checking, ensure the autoload paths configured in config/application.rb or engine initializers are consistent with Zeitwerk naming conventions — but that is a concern for the underlying Ruby/config files, not this script itself.

[kitcommerce]

Security Review

Verdict: PASS

Reviewer: Security

Summary

This PR simplifies script/default_appraisal_zeitwerk_check from 59 lines to 18 lines. The script is an internal CI-only tool that verifies Zeitwerk autoloading across engine dummy apps.

Findings

• No secrets or credentials in the script.
• No injection risks: The script uses no user-supplied input — all values are hardcoded literals (core, admin, storefront, hardcoded URLs).
• set -euo pipefail is used correctly, ensuring the script fails fast on errors or undefined variables.
• No network exposure: The curl and mongo commands target localhost only and are service health checks, not authenticated endpoints.
• No sensitive data handling: The script only runs zeitwerk:check rake tasks in test dummies.
• The removed code (Docker port discovery, rbenv detection) had no security concerns either.

Recommendations

None. Clean simplification of an internal CI script with no security implications.

Simplicity Review

      "line": 13,
      "issue": "cd into engine dir then cd ../../.. in a loop body is fragile relative navigation. If the loop body ever grows or the engine path depth changes, the backtrack silently breaks.",

      "file": "script/default_appraisal_zeitwerk_check",
      "line": 14,
      "issue": "|| exit 1 is redundant; set -euo pipefail at line 3 already causes non-zero exits to abort the script.",
      "suggestion": "Remove the || exit 1 — let set -e do its job. Reduces noise and keeps the pattern consistent with how the rest of the script implicitly relies on set -e."
    }
  ]
}

The 59→18 line reduction is the right move — the removed Docker port-mapping detection and rbenv branching were genuine complexity that didn't need to live here. Both remaining notes are LOW and non-blocking. The deprecated mongo CLI and missing RAILS_ENV export are out of scope for this review (correctness/compatibility).

🔒 Security Review — PR #1055

Reviewer: rails-security sentinel
Scope: Shell script script/default_appraisal_zeitwerk_check

Findings

#	Severity	Finding
—	—	No security issues identified

Analysis

1. Shell injection risk: The script uses only hardcoded loop values (core admin storefront) — no user-supplied input enters any command. No injection vector.
2. Secret exposure: No credentials, tokens, or secrets present. Script runs zeitwerk:check, a read-only Rails task. Clean.
3. set -euo pipefail: Proper strict mode is set, preventing silent failures. ✅
4. Path traversal: cd targets are relative to fixed engine names; no external input influences paths. No risk.
5. Permissions: File is 0755 (executable) which is expected for a script. No SUID/SGID concerns.

Verdict

✅ APPROVED — No security concerns. This is a simple, well-constrained CI helper script with no external input, no secrets, and no network calls.

🧪 Test Quality Review — PASS with notes

PR: script/default_appraisal_zeitwerk_check (CI shell script)
Reviewer role: test-quality (Wave 2)

Coverage Assessment

This PR is a CI-only shell script, not application or library code. The Zeitwerk check task itself serves as the functional test — if autoloading is broken, the task exits non-zero and CI fails. That's appropriate for this type of artifact.

What the script tests:

• Runs bin/rails zeitwerk:check for core, admin, and storefront dummy apps
• set -euo pipefail means any unhandled command failure propagates as a CI failure
• Three sequential checks give per-engine signal rather than a single opaque pass/fail

Gaps / concerns (non-blocking for test-quality):

1. cd ../../.. is fragile (already noted in Wave 1 architecture review). If any cd leg fails mid-loop, the script continues running from an unexpected working directory, potentially re-running the wrong engine or silently skipping one. The || exit 1 only covers the Rails command, not the cd itself. Recommend:

   (cd "$engine/test/dummy" && bin/rails zeitwerk:check) || exit 1

   This runs each leg in a subshell — no directory mutation escapes.

2. No Redis wait — The service-wait block covers Elasticsearch and MongoDB but not Redis. Workarea uses Redis for sessions/cache at boot. A missing Redis wait could cause false zeitwerk:check failures in CI if Redis isn't ready before the Rails boot.

3. RAILS_ENV not exported — The previous script explicitly set export RAILS_ENV=test. The new script omits this. If RAILS_ENV isn't set in the CI environment, the check runs in development mode, which may load different autoload paths and give a misleading PASS.

4. No bats/bash unit tests — acceptable for a repo that doesn't have a shell testing convention. CI integration test is sufficient here.

Verdict: The core testing mechanism (Zeitwerk task) is sound. The subshell cd fix and Redis wait are the most impactful improvements. Not blocking merge, but the cd ../../.. pattern should be addressed before this runs in production CI.

⚡ Performance Review

Verdict: PASS

Reviewer: performance-oracle (Wave 3)

Analysis

This PR replaces a 59-line bash script with an 18-line version. From a performance perspective, the new script is strictly better:

Improvements over old version:

• Eliminates multiple subprocess spawns: docker ps, docker port, grep, head — all gone. The old script forked multiple processes to detect Docker-mapped ports; the new script skips that entirely.
• timeout 60 bounds both service-wait loops, preventing indefinite blocking in hung CI environments.
• sleep 2 polling interval in the service-wait loops is appropriate — not busy-waiting.

Potential concern (minor / acceptable):

• The for engine in core admin storefront loop uses relative cd ../../.. to return to root after each engine check. This is correct for three iterations but relies on consistent directory depth. No meaningful performance impact — just a note for robustness.
• Each engine check spawns a full Rails process (bin/rails zeitwerk:check). This is unavoidable for the check — no optimization opportunity exists here.

No performance anti-patterns found. The script is lean, bounded, and runs fewer subprocesses than its predecessor.

Performance review complete. No blocking findings.

Documentation Review

Verdict: PASS_WITH_NOTES

Findings

• PR Description: Good — explains what the script does (waits for services, runs zeitwerk:check per engine, exits non-zero on error), why it exists (CI job from PR WA-VERIFY-068: Add CI invocation of verify-zeitwerk.sh to default-appraisal job #1035 was failing due to missing script), and the client impact (none). ✅
• No public API changes: CI script only.
• CHANGELOG: No entry needed — CI-only change.

Observations (PASS_WITH_NOTES)

• The script adds 13 lines and removes 54 lines (net reduction, likely replacing a larger/different script). The PR description explains the new script's behavior clearly, but doesn't mention what was removed or why — a brief note would help reviewers understand the full scope of the change.
• The script itself could benefit from a brief header comment (e.g., # Runs zeitwerk:check for core/admin/storefront after services are ready.) so it's self-documenting without requiring the PR description. Shell scripts used in CI are often read in isolation months later.
• "How to verify" is implicitly "run it in CI" — acceptable for a CI script, but a note like "To test locally: ensure MongoDB/Redis/Elasticsearch are running, then bash script/default_appraisal_zeitwerk_check" would improve the PR description.

Recommendations

• Consider adding a one-line header comment to the script file for future discoverability.
• Minor: document what was deleted/replaced in the PR description.
