Counted today: the arc has four plans on disk and nine deliverables, and had already absorbed three PRs (#1085 landing §11.3, #1087 and #1089 regrading it) — while INTEGRATION_PLANS.md enumerated ZERO of the four and STATUS_BOARD.md carried ZERO rows matching D-ARW. Both are mandatory at plan-add time. The cost was not bookkeeping. Asked which plans come before cognitive-shader-driver so the dependencies are ready, a session consulting the enumeration finds the shader-adjacent neighbours (ARC-B ownership reassessment, hhtl-thinking-tables, mask-algebra-revision-read, alpha-channel-rung-overlay, cascade-seal-register-grid) and NOT the arc that currently owns the question — whose §0 thesis and D-ARW-5 gate answer it directly. Rule: an index answers dependency questions only for arcs that are in it, and an absent arc is indistinguishable from a nonexistent one. A stale entry contradicts something; a missing entry contradicts nothing. Filed retroactively with the omission recorded IN the entry rather than backdated silently. The index entry carries the arc's own sequencing — D-ARW-5 (atom/loco/R2IL reuse census) gates adding primitives, D-ARW-7/8 are Held on their predecessors, and the addendum's A9/A10 forbid a parallel D-id family and a new DTO before the surviving surfaces are shown insufficient. Supersession index regenerated AFTER the board write, per the rule this repo's CLAUDE.md now carries: coverage for the owner plan moved 2/9 → 3/9, a live confirmation that the board is a generator input.

Codex P2 on #1090: recording #1089 as a second "method-transfer" regrade is false provenance. Correct, and the imprecision was mine in three places. #1085 landed §11.3's method-transfer note. #1087 regraded THAT note to partial prior transfer. #1089 struck a SEPARATE claim in the same section — that a shared `FacetTier::morton` is a certified one. Two regrades, two different claims, neither the other's follow-up. Writing "regraded #1087/#1089" under one label smeared them together, which is exactly the kind of thing a status dashboard exists not to do. One factual note for the record: codex reviewed a7828ee, whose base was #1087's merge, so #1089 was genuinely not in its view — its "the reviewed diff does not modify §11.3" is true of #1090's own diff, and #1089 does touch §11.3 (a391203, 43 lines in the audit plan). The finding is right about the label; the inference that no §11.3 change exists is an artifact of the pre-rebase base. Split in all three carrying sites (STATUS_BOARD row, INTEGRATION_PLANS entry, EPIPHANIES entry), with the smear recorded rather than quietly rewritten.

…ten rows; restore D-ARW tracking Two independent items, both source-verified against cc0046f. 1. §F third correction. #1112 migrated alpha / alpha_tunnel / rung_schedule into lance-graph-contract and added planner::rung_horizon, so the mechanism §F has now been wrong about twice exists in-tree and names its own type. §F.1's "ten rungs = ten rows, sparsely occupied, at one address" has the wrong noun: AlphaTunnel holds lanes: Vec<AlphaOverlay> built by mapping (0..LEVELS) over ONE borrowed AlphaAllocation (alpha_tunnel.rs:73-89, LEVELS=10 at rung_schedule.rs:59). One lane costs one empty Vec; the module states outright that ten lanes must not mean ten address sets. And "split tunnel" names a read/write path split (reads share the baked spine lock-free, writes go to the overlay at the same addresses, alpha_tunnel.rs:12-18) which neither earlier reading contained. Two things checked rather than assumed, both cutting against the convenient conclusion: the Arrow/Lance storage glue deliberately stayed with the storage crate (alpha.rs:1-5), so lance-graph can express a rung stamp but still not persist one, leaving §F.2's persistence table accurate; and D-ACR-3's blocker survives, because mailbox_owner() still has zero callers outside its module (the only other occurrence is a doc mention at alpha_tunnel.rs:33) while the tunnel enforces one-writer structurally via per-lane &mut. Adds F-RLR-12: a correction must cite the type's definition, not substitute a different English noun for its shape. 2. D-ARW STATUS_BOARD rows restored. Verified gap: the board's deliverable dashboard had zero D-ARW/F-ARW rows while EPIPHANIES, LATEST_STATE and PR_ARC_INVENTORY all carried references, and #1094/#1095 had merged real artifacts. Rows derived ONLY from the merge commits and the files they added (e61d25a, e4db066) — never from #1090's enumeration, which #1093 reverted and #1096 rules non-citable. Scope is deliberately the two deliverables with merged artifacts, not a re-enumeration of D-ARW-0..8, which stays absent pending the operator gate #1096 requires. Board writes post-checked per the never-truncate law (STATUS_BOARD 1662->1682, EPIPHANIES 23989->24054); supersession index regenerated after the board writes and verified current.

D-ARW-0..8, and had already absorbed three PRs — #1085 landing §11.3, #1087 and #1089 regrading it.Why this was not bookkeeping
Asked "which plans come before
cognitive-shader-driver, so the dependencies are ready?", a session consulting the enumeration finds the shader-adjacent neighbours — ARC-B ownership reassessment,hhtl-thinking-tables,mask-algebra-revision-read,alpha-channel-rung-overlay,cascade-seal-register-grid— and not the arc that currently owns the question, whose §0 thesis andD-ARW-5gate answer it directly.The failure is silent and symmetric: what is missing from an index is exactly what an index cannot show you. A stale entry at least contradicts something; a missing entry contradicts nothing. That asymmetry is why the hygiene rule says same commit — "add it when the arc matures" degrades to "add it when someone notices", and noticing requires already knowing the arc exists.
What the entry carries (so the next reader gets the ordering, not just a pointer)
lance-graphowns reusable reasoning mechanics over canonical graph addresses; cognition rides the existing Alpha substrate; policy composes through the existing ogar-loco / R2IL membrane. Discovery-first, not a representation proposal.reason.rs::rung(derivational depth) must never be equated withcognitive_shader::RungLevelmerely because both say "rung", and the §2.2 NO-BUY on another "origin" field.D-ARW-5(atom/loco/R2IL reuse census) is what gates adding primitives;D-ARW-7/8are explicitly Held. The addendum's A9 ("does not mint a parallel D-id family") and A10 STOP feat: add Belichtungsmesser HDR popcount-stacking early-exit cascade #8 (no new DTO to reconnect the field seam until surviving surfaces are shown insufficient) say the same from the other side.PerturbationDto.energy: Vec<f32>dropped/unconsumed,top_k → threshold → min..=max → ColumnWindowa bounding window not a field mask — and "no survivingcodebook_id ↔ (row,col)mapping today".Housekeeping
Filed retroactively, with the omission recorded inside the entry rather than backdated silently, so the gap stays legible.
Supersession index regenerated after the board write, per the rule
CLAUDE.mdnow carries — and it moved: owner-plan coverage2/9 → 3/9. A live confirmation that the board is a generator input, which is the whole reason the ordering rule exists.Board entry:
