## 2026-09-23 — lance-graph #1271 MERGED (`d90600d`); OGAR #307 and z8run #1 merged

The "unmerged" section below is now on `main`: `lance-graph-report` (workspace
member) and `lance-graph-report-ogar` (excluded; needs OGAR #307, merged).
Contract inventory unchanged. D-RPT-1..4 shipped; still open: D-RPT-5.

## 2026-09-23 — ReportPlan + report-as-OGAR-projection (branch `claude/brave-mayer-65y3cy`, unmerged)

### Current Contract Inventory — UNCHANGED (no contract type added; two crates added)

## 2026-09-23 — lance-graph PR #1271 (merged `d90600d`, branch `claude/brave-mayer-65y3cy`, head `d4dd251`, 1 commit) — ReportPlan fold substrate, zero-copy pivot, reports as OGAR projection sources

- **Added:** `crates/lance-graph-report` (member): `ReportPlan` lowering into
`lance-graph-quack` only (no second evaluator); role-free `PhysicalKey`, so a
pivot rotation is the same `Arc<CellSpace>` with a new `View`; dense/sparse
accumulator with no Cartesian allocation; string-free execution core with a
source-fence test; KV/CAM boundary over the contract's `ContentStore`.
`crates/lance-graph-report-ogar` (excluded): `ReportSource` answers OGAR's
`DocObjectSource::grid_of`, so a report is one more addressed object in a
`DocCompose` (Live / Revision; Snapshot falls to the slot fallback).
- **Locked (test-pinned):** execution allocates the same bytes at N and 64·N;
rotation allocates < 64 B (view) / < 256 B (reinterpret); fold does 0 CAM and
0 KV work. Each falsifier disable-verified.
- **Companions:** OGAR #307 (merged; `SlotOutcome::Grid`); z8run#1 (open).
- **Deferred / open:** D-RPT-5 composite-key group fold
(`ISS-REPORT-NO-COMPOSITE-KEY-GROUP-FOLD`); OGAR `DocRenderer` is still
spec-only; Snapshot has no content-addressed store.
- **Confidence:** high for the fold/pivot contract (oracle-checked, 27 tests);
bench figures are one avx2 run, unrepeated.

## 2026-09-19 — lance-graph PR #1252 (merged `8545a555`, branch `claude/great-pascal-k96kok`, head `16a0130d`, 5 commits, docs only)

Mixed PR (hygiene + rulings), so not exempt under the termination clause. Only
