## 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` skipped the restore when an interior edit inside
the pending proposal's range orphaned the exact-substring anchor (INV-11),
yet removed the proposal and reported success — ✗ Reject silently left the
(edited) proposed text in the buffer. Evaluate the issue's fix directions
(a/b/c), TDD the fix, ship branch → PR → merge per §5.4.
## Pre-state
- `origin/main` at `d8f2d73` (session 0065's native-surfaces migration
shipped; #70/#71 filed from its final review).
- Three concurrent sessions in flight (0061, 0062, 0063 placeholders);
session 0062 occupied the canonical checkout, so the #134 claim guard
refused a shared-tree claim — this session created worktree
`.claude/worktrees/fix-70-inv5-reject-gap` off `origin/main` FIRST and
claimed 0066 from inside it (the inverted order the init documents).
- Canonical checkout's untracked files (`specs/`, a plan doc) belong to the
concurrent session and were left untouched.
## Arc
1. **Init.** Claimed 0066 from the worktree; #70 checked ELIGIBLE (type/bug,
R2b; needed `--host git.benstull.org` + the issues token service). Fetched
the issue body carrying the three fix directions.
2. **Design.** Explored `proposalController.ts` / `anchorer.ts` /
`editorProposalController.ts`. Chose direction **(a)** — tracked applied
range — with **(b)** honest hard failure as fallback; rejected **(c)**
fuzzy resolve (INV-11: never guess). Key insight: `state.live` is
shift-maintained but clobbered to a collapsed placeholder by any
intervening `renderAll`, so a dedicated `appliedSpans` map with explicit
trust semantics was designed instead.
3. **Plan.** `docs/superpowers/plans/2026-07-02-70-inv5-reject-after-interior-edit.md`
(4 TDD tasks). Fused single-session path (leaf bug), executed inline.
4. **Tasks 14** (commits `a9f8dd0`, `82cea74`, `ddd634b`, `f47dfbc`):
appliedSpans + revertInPlace fallback (E2E repro failed-then-passed);
hard-failure lock test (first cut used a whole-buffer rewrite and FAILED —
VS Code minimizes workspace edits, so it decomposed into interior hunks
the span legitimately survives; switched to a boundary-straddling
deletion); rejectAll `{reverted, skipped}` parity; fullLoop reject leg now
tweaks inside the pending range first (retiring its deliberate avoidance).
5. **Review wave** (high-effort multi-agent workflow; 10 CONFIRMED findings,
9 fixed in `e389406`): pure `shiftTracked` in anchorer (+11 unit tests;
insertion-at-span-start lands BEFORE the span), tracked spans cleared on
doc close (disk can change with no events), rebuild-only resync (duplicate
-text resolve can't clobber continuous tracking), `guard.isReadOnly` on
finalize/revert (INV-16), "Discard proposal (leave text)" action on the
hard-fail warning (reload leaves no other dismissal path), CodeLens pair
anchored at the tracked span (the fixed path stays reachable from the
primary gesture), QuickPick batch menu routed through the reporting
commands, one `clearProposal` helper (fixes `reject()`'s stale bookkeeping).
The 10th finding is pre-existing → filed **#74**.
6. **Ship.** PR #73 → squash-merged to `main` as `7583165`; #70 auto-closed.
312 unit + 94/5 host E2E green (1 occasionally pending = the known #54
undo-capability probe). Plan archived to the content repo
(`plans/2026-07-02-70-inv5-reject-after-interior-edit.md` at `0019d58`).
Remote branch `s70-inv5-reject-gap` deleted after merge.
## Deployment pipeline (§9)
This app is a VS Code extension with no deploy infra (no flotilla/PPE stage
exists — per prior sessions, "no deploy pipeline (extension, no flotilla)").
The localhost stage ran in full: typecheck + 312 unit + 94/5 host E2E green.
Nothing to deploy; no release tag applies.
## Cut state
- `origin/main` = `7583165` (the #70 fix). Worktree branch merged; remote
branch deleted; worktree torn down at finalize.
- Issue #70 CLOSED (auto, via PR). Issue #74 (bug P3) OPEN — filed this
session: `resolve()` accepts a single exact occurrence without a context
check (pre-existing; duplicated block can hijack any anchor consumer).
- Concurrent sessions 0061/0062/0063 still INPROGRESS — not mine to adopt
(live, per their stamps).
## Operator plate
- **Manual smoke owed:** the "Discard proposal (leave text)" warning button
(native notification — not E2E-testable) + the smokes already owed from
sessions 0062/0065.
- Prod promotion: N/A (no deploy pipeline for the extension).
## Deferred decisions
No low-confidence calls this session. (Design forks — (a)+(b) over (c), the
distrust semantics, squash-merge — all followed the issue's own directions,
existing invariants, or repo convention.)
## Next-session prompt
```
/goal Plan and execute #71 — surface-polish batch from the native-surfaces final review (6 small items listed in the issue body)
