What changed

ISS-REPORT-NO-COMPOSITE-KEY-GROUP-FOLD (ISSUES.md) and D-RPT-5 (STATUS_BOARD.md). The issue said Report lacked a composite-key group fold. It has one, verified in source at aa569bc5:

• mask-risc GroupKey::Pair { hi, lo, stride } (ir.rs:505), executed for Count / Min / Max / SumSym and power sums (exec.rs:1995-2085);
• Quack GroupAddr::Pair, lowered at lib.rs:2460 and checked against DuckDB in tests/duckdb_differential.rs;
• ndarray masked_group_count_u32_pair and its siblings (src/simd.rs:933-957, ndarray af4910a1).

The fold landed in 869ba24d (#1275) on 2026-09-23, the day the issue was filed. Since #1331, lance-graph-report/src/exec.rs:42-69 has named the real gap as destination binding / coordinate resolution, and Report deliberately does not lower to the dense Pair product. The issue and the D-RPT-5 row now say this in dated supersession notes. The original text, including the 32×12 / 4M rows / 25 passes / 177 ms measurement, is kept as history.

The open question is restated: can a source-attested semantic destination be bound to a compact, witnessed local coordinate so that Report can use the existing Local / Via keyed fold? The issue relates it to D-DT64-Q0, EXO-46, ADMISSION-B and DR64³. None of these provides the binding today.

TECH_DEBT.md, existing rows only (no new debt, per H-12):

• TD-SIMD-SWEEP-W2: the ndarray_bridge.rs raw intrinsics all sit under cfg(not(feature = "ndarray-hpc")), and ndarray-hpc is a default feature.
• TD-NDARRAY-PATCH-0_16: lance-6-era wording refreshed. The published lance-index-13.0.0 still requires crates.io ndarray = "0.16.1", used only in vector/bq/builder.rs (EXO-113 confirmed). The fork path conflicts with E-LANCE-IS-UPSTREAM-AUTHORITATIVE-1.

New entry entries/2026-10-27-harvest-integration-composite-key-and-simd-scope.md records the CP-1..CP-7 dispositions, the tests still required and the operator decisions. entries/README.md is regenerated.

Still open

Tests:

• wasm mul_add parity, stated per realization and feature set, with relaxed-simd named as in or out of scope. This is separate from the reduce_sum ordering difference. Both are ndarray-side.
• A parity test of the two 256-immediate ternlog dispatchers (mask-risc and lgj-abi).
• Report pass count with a bound ordinal against the 25-pass baseline, once a binding exists.

Operator decisions:

• EXO-112, the contract's ndarray dependency shape. It blocks EXO-111 and the zero-dependency comment (CP-6).
• EXO-46, the production binding membrane.
• Whether the ternlog dispatcher moves into ndarray.
• Path 1 or path 2 for TD-NDARRAY-PATCH-0_16.

Not in this PR: the stale lance-6.0 comment at crates/lance-graph/Cargo.toml:27-28. Fixing it is a manifest edit.

Checks run locally

All passed: entries_index.py --check, fruits_index.py --check, epiphany_provenance.py, compact_epiphanies.py --check, append_only_gate.py origin/main (no protected file shrank) and citation_decay.py --since origin/main (0 new decays). SUPERSESSION-INDEX.md and FRUITS.md regenerate byte-identical.
