Full Repo Coverage Roadmap

Goal

Freeze the remaining high-ROI whole-repo coverage work into one stable roadmap now that the non-React phase is finished.

Lock Rules

• Phase: full repo, including React.
• Frozen threshold: raw score >= 8 from 2026-03-24-coverage-priority-files-testing-review-full-repo.tsv.
• Queue is file-first. Do not collapse this back into package sweeps.
• Future passes should mark items done, removed, or deferred. Do not reshuffle the whole roadmap unless:
  • a file is deleted
  • a file drops below the threshold because it already has direct coverage
  • architecture work makes a queued file obviously not worth touching anymore

Execution Policy

• Finish Tier 1 first. That is every remaining score >= 9 file.
• Then finish Tier 2. That is every remaining score = 8 file.
• Stop and rerun coverage before touching the score-7 ring.

Deferred From The Current Phase

• [deferred] score-7 ring and below Reason: still real, but the clean stop for this phase is the full score >= 8 queue. Rerun coverage before touching the score-7 leftovers.
• [deferred] thin plugin entrypoints and wrapper components that still score high only because the hook cluster under them is uncovered Reason: the hook or util is the seam. Testing the wrapper too early is coverage cosplay.
• [deferred] giant architecture slabs outside this threshold, like PlateEditor.ts and getSelectedDomFragment.tsx Reason: real seams, but not the best spend before the current React hook and util queue is finished.

Update Rule

• When a file gets direct tests, flip it to [done]. Do not remove it.
• When a file is deleted or replaced, flip it to [removed] with a one-line note.
• When a file proves fake ROI, flip it to [deferred] with a reason.
• Do not reshuffle the queue because the next audit has a slightly different vibe.
