+## Session arc
+
+1. **Claim.** Resumed via `/goal next` (after session 0043 shipped #42); claimed
+   session 0044 for #47. Clean `main` baseline.
+2. **Anchor gate.** #47 (`type/feature`) covered by the graduated combined design
+   → §4.3 R3 satisfied.
+3. **Deep code read.** `splitBlocks*`/`diffBlocks`/`diffToHunks`/`EditHunk`,
+   `runEditAndPropose`, `proposalController.accept`/`applyAgentEdit`, and crucially
+   `pendingEdits.matchEvent` (one registration per change event → drove the INV-40
+   sequential-apply decision).
+4. **TDD `diffToBlockHunks`.** First attempt (coarsen word-hunks) failed a
+   reconstruction case — discovered `diffToHunks` can emit OVERLAPPING hunks
+   (anchorInsertion over-absorbs). Switched to block-key alignment with
+   replacement-from-rewritten-raw → green.
+5. **Model + wiring + INV-40 accept.** Added `granularity`; document branch →
+   `diffToBlockHunks`; `acceptBlock` intra-block sub-diff. The overlap bug then
+   resurfaced in `acceptBlock` (batch apply) → split `diffToHunks` into raw
+   `wordEditHunks` (disjoint) + anchoring wrapper; `acceptBlock` uses raw → green.
+6. **Verified + shipped** (214 unit, 69/5 E2E), self-reviewed, PR #50 merged,
+   #47 closed, memory + transcript updated.
