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

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.
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.
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.
Tasks 1–4 (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).
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.
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)
