Seven-agent CR surfaced correctness defects in the build/deploy/promote
pipeline and in the no-public-env-shell-read oxlint rule. This commit
closes the false-green paths and broadens lint coverage.
Workflow fixes:
- showcase_deploy.yml: drop `continue-on-error: true` on the redeploy-summary
artifact download. The dispatch path is already guarded by the `if:
workflow_run` clause, so the bash "no summary" branch handles legitimate
manual dispatches. A genuine workflow_run download failure must now fail
loud instead of silently widening verify to the full service set against
stale `:latest`.
- showcase_build.yml: redeploy-staging now intersects the build matrix with
the aggregator success set (`needs.aggregate-build-results.outputs.results`,
status == "success") before producing the redeploy CSV. Failed/skipped
slots no longer get redeployed (which would just re-pull stale `:latest`
and look healthy).
- showcase_build.yml: `notify-all-builds-failed` now additionally requires
`needs.build.result == 'failure'` so it doesn't Slack-spam when the build
job was SKIPPED (verify-image-refs upstream failure).
- showcase_build.yml: `notify` now lists [build, aggregate-build-results,
redeploy-staging] in `needs:` so aggregator/redeploy failures still emit
a Slack signal. `if: failure()` still skips when none of the needs failed.
- showcase_build.yml: `set -euo pipefail` on the Prepare build args step
so a transient $GITHUB_OUTPUT write failure can't ship images without
COMMIT_SHA/BRANCH baked in.
- showcase_deploy.yml: `enforce-redeploy-gate` now also trips on a
resolve-matrix failure (`needs.resolve-matrix.result == 'failure'`) so
an upstream crash that leaves `redeploy_red` empty can't bypass the gate.
- Doc-comment accuracy: drop stale `(PR #5093)` reference; correct the
env-IDs source-of-truth comment; document the optional `skip_build` field
in ALL_SERVICES; clarify that health_path is informational and verify
uses per-service drivers; add the missing `resolve-targets` step 0 to the
promote workflow's "Order:" header.
Aggregator fix (RED-GREEN):
- aggregate-build-results.ts: throw on zero slot dirs. The job is gated
upstream on has_changes == 'true', so zero slot dirs is a broken artifact
download, not a legitimate empty build set. Silently emitting
any_success=false + results=[] is indistinguishable from "all builds
failed" and lets the deploy workflow fall back to probing the full
service set against stale `:latest`. Refuse the ambiguity.
- aggregate-build-results.test.ts: existing empty-INPUT_DIR test was
updated to assert the throw (was: return []).
Oxlint rule (RED-GREEN):
- no-public-env-shell-read.mjs: handle destructuring reads
(const { NEXT_PUBLIC_X } = process.env and aliased form), template-literal
computed keys (process.env[\`NEXT_PUBLIC_X\`]), and explicitly skip
assignment-LHS / `delete` targets (writes are not reads). Optional
chaining already worked through the existing MemberExpression path.
Aliasing (`const e = process.env; e.X`) is intentionally documented as
out of scope (needs scope tracking). Description sharpened to say the
rule guards a specific banned-key set, not all NEXT_PUBLIC_* reads.
- .oxlintrc.json: tighten the off-override glob from
`showcase/**/*runtime-config*` to
`showcase/**/lib/runtime-config*.{ts,tsx}` so it only silences the
intended implementation files, not arbitrary paths containing that
substring.
- lint-rule-no-public-env.test.ts: rewritten as table-driven coverage of
every BANNED_KEYS entry (dotted + bracket-string forms), every ALLOWED
key (asserting non-firing), all new variants from the rule expansion,
the assignment/delete non-fire cases, and override scoping
(runtime-config exempt; packages exempt; shell-tree non-runtime-config
flagged).
Validation:
- actionlint on all three workflows: 8 pre-existing findings (depot label,
pre-existing SC2086 infos in untouched steps); my edits add zero.
- python3 yaml.safe_load: all three workflows OK.
- vitest aggregate-build-results.test.ts: 6/6 pass (incl. new throw test).
- vitest lint-rule-no-public-env.test.ts: 34/34 pass.
- vitest full showcase/scripts suite: 1654/1654 pass across 46 files.
- ruby showcase/bin/spec/all_tests.rb: 87 runs, 0 failures.
- Intersection jq proof (matrix a,b,c × success a,c) → "a,c"; all-failed
→ ""; skipped status excluded.
Build matrix slots now publish per-slot build-result-<dispatch_name>
artifacts containing {service, status}. A new aggregate-build-results
job downloads every per-slot artifact, merges them via the shared
mergeBuildResultFiles helper, and uploads the canonical build-results
artifact (results.json) for cross-workflow consumption.
The deploy workflow's resolve-matrix step now downloads build-results
via gh api .../artifacts/<id>/zip and filters its verification matrix
from the structured JSON success set. No more gh api .../jobs calls,
no more capture("^build \\(") regex on job names — those silently
break on job-name renames. The contract (service + status enum) is
enforced in one place: showcase/scripts/lib/build-outputs.ts.
