## 2026-08-05 — branch `claude/x265-x266-plans-review-h9osnl` (PRs #892 MERGED `e9a2faf` + #891 MERGED `0c138b7`) — the four-arc session lands: whole-book fix, ignition probes, five-axis measurement, no-pump + ack-theater deletion

The oversized branch (68 commits, +24,956/−2,305) was split for reviewability at the operator's direction: **#892** = arc 1 (bible_wave Malachi-truncation fix + `deepnsm_v2::corpus` + the stance lift into `nars::stance` + D-BLW-1..4 with the tenant-not-shard retractions); **#891** (rebased onto main post-#892, pure replay, 29 commits) = arcs 2–4 (PROBE-IGNITION + D-IGN-B + PROBE-IGNITION-64K green; measure-64k-axes v1–v3 with Stage A0 + M-arm/O-arm both measured NEGATIVE as pre-registered findings; seal-vs-temporal dual-authority doctrine; hot-version-window v4 design banked NOT built; `E-PROGRESSION-IS-EXISTENCE-NOT-COMMAND-1` + the ack theater deleted with `PhaseCensus` as the message-free visibility surface).

**Contract-inventory deltas:** `lance_graph_supervisor::kanban_actor` is now visibility-only — `PhaseCensus` (new), `mul_target`, `parse_kanban_step`; `KanbanActor`/`KanbanMsg`/`KanbanRouteError` + 5 RPC drivers DELETED. `lance_graph_planner::nars::stance` (new module, lifted from the probe example). `deepnsm_v2::corpus` (new module). onebrc-probe `lane-e` feature no longer depends on supervisor/ractor.

**Standing gates:** D-BLW-5 build operator-paused; D-HWV-1 hot-window build gated on operator word; `--features cycle-driver` CI step still unarmed (operator-approved changes only); `ISS-MARM-T1-4X-A0-GAP` open.

## 2026-08-04 — branch `claude/x265-x266-plans-review-h9osnl` (PR #887) — D-KIA-C1b SHIPPED: the additive `jc` statistics battery

`crates/jc/src/stats.rs` — **κ** (`cohen_kappa`, the gap that blocked **D3's fusion falsifier**, now closed), **ω** (`omega_total`), **φ** (delegating to `pearson`, `&[bool]` input), **R / R²** (`multiple_r_squared`, OLS with intercept), **η²** (`eta_squared`), and the significance companions (`t_test_one_sample` / `_paired` / `_welch` / `_student`, `anova_one_way`) over one shared regularised-incomplete-beta core. **107 lib + 11 doctests green, clippy-clean.**

## 2026-08-05 — lance-graph #891 (MERGED `0c138b7`) — ignition + 64k measurement + no-pump: probes, five-axis harness, M/O arms, hot-window design, ack-theater deletion

**Head at merge:** `463f807` (29 commits — the branch's arcs 2–4 after #892 split out arc 1 and the branch was rebased onto main; pure replay, zero conflicts). 48 files, +14,353/−1,816.

- **Added.** `tests/probe_ignition.rs` (2/2, 11 dual-half gates — first driver of the write path, 64 real owners), `tests/d_ign_b_lenses.rs` (arming z∈{1..4} selects the stance reading; z=5 blocked), `tests/probe_ignition_64k.rs` (65,536 real 1:1 owners, one seal, fleet-wide rest), `examples/measure_wal_curve.rs` (five-axis harness + M/O arms), `supervisor::kanban_actor::PhaseCensus` (the message-free visibility surface), plans `measure-64k-axes-v1..v4`, knowledge `observer-effect-tfpn-doctrine.md` + `seal-vs-temporal-ordering-information.md`.
- **Locked.** `E-64K-1TO1-OWNERS-IS-THE-MAIN-MODEL-1` (operator order: 64k 1:1 owners = THE main model; one-tenant = harness shape). `E-PROGRESSION-IS-EXISTENCE-NOT-COMMAND-1` (operator: no pump, no ack, no scheduler — think→seal→publish→next cycle reads; ack/SLA vocabulary lives only in external consumer membranes, e.g. OGAR's ActionHandler parity runtime). `E-SEAL-AND-TEMPORAL-ARE-DIFFERENT-OBJECTS-1` (dual authority: temporal.rs = temporal, seal = ordering; the gap is a research question). The ack theater DELETED from source (`KanbanMsg`/`KanbanActor`/5 drivers/`run_to_absorbing`); the kanbanstep (`VersionScheduler::on_version`) explicitly NOT theater. Measured negatives locked as findings: Morton reorder LOSES (Δtotal +35.2 ms, digests matched); temporal-sourced ordering DIVERGES from the seal's (O-arm); WAL knee NOT REPRODUCIBLE (unclaimed).
- **Deferred.** D-BLW-5 build (operator-paused); D-HWV-1/EXP-HOT-WINDOW build (design banked, panel-hardened, gated on operator word); A-arm allocator decomposition; `ISS-MARM-T1-4X-A0-GAP` (open measurement defect); PROBE-SEAL-VS-TEMPORAL ×3 (pre-registered, not run); the `--features cycle-driver` CI step (operator-approved changes only); "scheduler" naming question on `VersionScheduler`/`NextPhaseScheduler` (semantics compliant, word is a drift vector).
- **Docs.** `measure-64k-axes-v4.md` (hot version window: barrier-flush fork, H-1..H-5), the v2 cross-note (two different 200 ms windows), TD-MESSAGE-RESIDUE resolved-by-deletion, `E-ACK-THEATER-DELETED-1` (zombie verdict + OGAR boundary check).

**Confidence (2026-08-05):** merged; probes green centrally; cycle-driver falsifiers still not CI-armed (recorded).

## 2026-08-05 — lance-graph #892 (MERGED `e9a2faf`) — Part 1 split: bible_wave whole-book fix + corpus module + stance lift + the BLW arm

**Head at merge:** `a214c65` (39 commits, the original #891 branch's first arc, split out for reviewability). 34 files, +10,645/−531.

- **Added.** `deepnsm_v2::corpus` (Gutenberg parser: full-footer match + exact-`***` skip; `CorpusSplit::crossed_new_testament` G1b two-sided gate; 9 lib tests in CI), `lance_graph_planner::nars::stance` (the lifted `stream`/`Interner`/`ReadOut`/`stance_panel`), examples `blw_binding`/`blw_tenant`/`blw_rows`/`blw_fusion`.
- **Locked.** The whole book actually runs: 31,102 verses / 40,767 triples; `reason_whole_book` fixed point with `dropped == 0`. An owner is a TENANT, not a shard (the 64-owner tiling RETRACTED — it fabricated 63 tenants; both offending harnesses deleted, one of them green-on-a-fabricated-shape). D-BLW-2 measured KILL; D-BLW-3 shipped+measured (attribution later regraded cohort-relative); D-BLW-4 3.27× at T=4 under its OWN harness gates (not the D-KIA-A2 protocol).
- **Deferred.** TD-BLW3B-ABC-DECOMPOSITION; D-KIA-A2 median-of-5 protocol.
- **Docs.** `batchwriter-kanbanstep-wiring.md` corrections; the cargo-hygiene agent rule; exec-run tag-files for the BLW lanes.

**Confidence (2026-08-05):** merged; the Codex P2 found on this PR's head (V8-only DROP key) was already fixed in #891's range (`max_ham` all-horizon gate) and reached main via #891's merge — recorded on the #892 thread.

## 2026-08-04 — lance-graph #887 — D-KIA-C1b: the additive `jc` statistics battery (κ, ω, R/η², t-tests, φ)

**Head:** `<this branch>` (entry written in the same commit as the change, per the hygiene rule's "SAME commit" wording; merge SHA follows on merge). 5 files: 1 new module + 2 visibility lines + 3 board/plan.
