gsxdsm f150a176b4 FN-6612: add test feedback-loop baseline reporting
Add a weekly baseline workflow for tracking test feedback-loop speed and flake pressure.

- Add a stdlib-only script to record gate and pnpm test timings alongside slowest test files and quarantine counts.
- Publish generated markdown and JSON baseline artifacts for #leads reporting.
- Document the weekly refresh process and add package scripts plus coverage for the baseline helper.

Test feedback-loop baseline

Publish this page's latest-cycle summary in #leads each week. The objective is signal-per-second: keep the merge gate thin, keep pnpm test flat or faster, and ratchet flaky/low-signal tests toward rescue or deletion.

Latest #leads summary

  • Cycle: 2026-W25 (2026-06-18T02:11:11.998Z)
  • Gate suite wall-time: 7.2s (trend: n/a)
  • pnpm test wall-time: 36.9s (trend: n/a)
  • Flake/quarantine count: 5 ledger entries across 4 files

Operating rules

  • Record a new row weekly with node scripts/test-feedback-baseline.mjs --record --gate-ms <ms> --test-ms <ms> after running pnpm test:gate and pnpm test.
  • Use the slowest-file list as the candidate queue for FN-5048 rewrites or deletion-ratchet review; do not add coverage for its own sake.
  • Quarantined tests remain on the 14-day rescue-or-delete clock in scripts/lib/test-quarantine.json; deleting a low-signal expired test is a valid positive outcome.
