Summary

• Run database integration checks alongside eight application shards per provisioning path and refresh duration weights from hosted GitHub runs. Keep integration on free GitHub runners and preserve realtime, PostgreSQL 16, and migration-replay coverage.
• Keep application build caches across edits to five developer-only guides. Published content, source, and configuration still invalidate the build; the existing type-check build flag now participates in the cache key.
• Observe actual document-lock contention in two integration fixtures, using the existing fixture policy of a five-second observation window and 10ms polling. Whole-test deadlines, SQL limits, and locking/persistence assertions remain unchanged.

Type of Change

• Performance improvement
• Bug fix

Testing

• Three successful paired hosted integration runs reduced the median slowest job from 408s to 373s (8.6%). All 6,354 case results match across both provisioning paths. Integration compute remains $0. A separate baseline-only fixture teardown failure is retained outside these timings; it was not retried into a green sample. Pair 1, pair 2, pair 3.
• Three paired documentation-cache builds: median build-command time after a guide edit fell from 219.3s to 5.2s. All 1,062 routes match, and all 1,759 static assets restore byte-for-byte. Both arms start with primed, isolated local Turbo caches and reset build outputs/generated inputs between samples. Remote cache is disabled. This models about $0.114 less compute per affected build, excluding setup, billing rounding, storage and credits; it is not a cold-compilation or monthly invoice-saving claim.
• Hosted lock regression: the old helpers fail under controlled scheduling delays; the complete fixed 27-case file passes three times on each provisioning path with the same delay. Attempt-count control, observation-deadline control.
• Final-head CI passed, including audits, type checks, application tests, browser and live Electron suites. The merged commit also passed every associated workflow, including staging push CI and macOS Electron coverage. Both reviewers finished at 5/5 with zero open threads.
• Lint, actionlint, 55 CI-routing/gate tests, and build-hash checks pass. Each excluded guide preserves the build hash; published MDX and Next configuration still invalidate it.

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing (existing lock fixtures pass the test-audit authoring gate and hosted negative controls)
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)

[Medium impact] The PR appears safe to merge; no actionable issues were found.

Summary

Separates database integration tests from eight application shards on each provisioning path and refreshes duration weights.

• Database integration checks run beside the eight app shards.
• Five developer guides no longer change the app build cache.
• Lock fixtures wait for PostgreSQL to show document contention.
