## Launch prompt

```
/goal Plan and execute #70 — fix the INV-5 reject-after-interior-edit gap (proposalController revertInPlace orphan path); fix directions in the issue body

```

## Plan

> Anchor: #70 (type/bug, P2 — ELIGIBLE R2b)

Fix the INV-5 reject-after-interior-edit gap: `revertInPlace` in
`src/proposalController.ts` skips the restore when the exact-substring anchor
is orphaned by an interior edit inside the pending range, yet still reports
success — ✗ Reject silently leaves the (edited) proposed text in the buffer.
Evaluate the issue's fix directions (a: tracked current range; b: hard
failure; c: fuzzy resolve), pick one, TDD the fix, host-E2E the repro sketch
(propose → optimistic-apply → type inside range → rejectById), branch → PR →
merge per §5.4. Session isolated in worktree `fix-70-inv5-reject-gap`
(concurrent sessions 0061/0062/0063 in flight; 0062 occupies the canonical
checkout).

## Progress

- Plan written: `docs/superpowers/plans/2026-07-02-70-inv5-reject-after-interior-edit.md`
  (4 tasks). Fix directions evaluated per the issue: **(a)** tracked applied
  span (new `DocState.appliedSpans` bookkeeping: set at optimistic-apply,
  re-synced on exact resolve, shifted through interior-safe edits, distrusted
  on boundary-straddling edits) with **(b)** honest hard failure as the
  fallback (warn, keep proposal, return false); **(c)** fuzzy resolve rejected
  (INV-11: never guess).
- All 4 tasks executed TDD on branch `worktree-fix-70-inv5-reject-gap`
  (commits a9f8dd0, 82cea74, ddd634b, f47dfbc): revertInPlace fallback,
  hard-failure lock test, rejectAll parity ({reverted, skipped} + batch skip
  report), fullLoop tweak-then-reject leg.
- Verification: typecheck + 301 unit + 94/5 host E2E green at each step.
- Execution note: first distrust-test cut (whole-buffer rewrite) failed —
  VS Code minimizes workspace edits, so the rewrite decomposed into interior
  hunks the span legitimately survives; switched to a boundary-straddling
  deletion (plan doc updated in place).
- Workflow code review (high) running; then push → PR → merge → close #70.

## Deferred decisions

_Autonomous-mode low-confidence calls the driver made and would have
liked operator input on. Appended as the session runs; surfaced at
finalize. Empty if none._
