Board/plan only. No code. Two independent items, both verified against source at cc0046f8.

1. §F, corrected a third time — and the second correction was the one that was wrong

#1112 migrated alpha / alpha_tunnel / rung_schedule into lance-graph-contract and added planner::rung_horizon. The mechanism §F has now been wrong about twice exists in-tree and names its own type, so this pass cites definitions instead of re-describing shapes.

reading verdict
ten residual deltas sharing a 480 B value slab wrong — withdrawn earlier
ten rows / ten tables at one address wrong — corrected here
ten lanes over ONE AlphaAllocation correct (alpha_tunnel.rs:73-89)

AlphaTunnel holds lanes: Vec<AlphaOverlay<'a>>, built by mapping (0..LEVELS) over a single borrowed allocation; LEVELS = 10 (rung_schedule.rs:59). One lane costs one empty Vec (:25-27), and the module states the prohibition outright: ten lanes must not mean ten address sets, because reserving is defined as costing zero rows (:22-24, restated at alpha.rs:454-456).

"Split tunnel" names a read/write path split — reads share the baked spine lock-free because &[NodeRow] may be shared; writes go to the overlay at the same addresses, as a compile-time property (alpha_tunnel.rs:12-18). Neither earlier reading contained this, though it is what the words say.

Two things checked rather than assumed, both cutting against the convenient conclusion

  • The persistence half did not migrate. The Arrow/Lance storage glue deliberately stayed with the storage crate (alpha.rs:1-5). lance-graph can now express a rung stamp and still cannot persist one — so §F.2's persistence table stays accurate and is scoped, not reversed.
  • D-ACR-3's blocker survives Contract: executed recipe dispatch + alpha channel/tunnel/scheduler migrate in; planner: rung_horizon (V2) #1112. mailbox_owner() still has zero callers outside its own module; the only other occurrence in crates/ is a doc mention at alpha_tunnel.rs:33. The tunnel enforces one-writer structurally via per-lane &mut (:29-38), not through the mailbox-ownership machinery D-ACR-3 exists to test. D-RLR-5's HELD reason is unchanged.

New fence F-RLR-12: a correction must cite the type's definition, not swap one English noun for another. Both wrong readings described a shape ("deltas", "rows") while the type had a name, a definition, and a module doc arguing its own design.

2. D-ARW STATUS_BOARD rows restored, narrowly

Verified gap: the 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 are derived only from the merge commits and the files they added (e61d25a1, e4db066c) — 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. The remaining ids stay absent pending the operator gate #1096 requires; that absence is a scope decision, stated in the section, not a second hygiene gap. This mirrors how #1099 re-derived D-MAR-1 from plan after the same revert.

…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.

P2 Badge Keep the two rung vocabularies distinct

When this plan is used to implement D-RLR-5, this verdict incorrectly treats AlphaTunnel as evidence that §F.1's (classid, rail) thinking-table rows were merely the wrong noun. The cited tunnel is explicitly indexed by the recipe ladder—rung_schedule.rs:54-59 defines levels as unset rung 0 plus recipe rungs 1–9, and alpha_tunnel.rs:66-70 says the same—while this plan's own lines 334–340 say that AlphaStamp.rung has not been proven equivalent to RungLevel. Until that mapping is established, these lanes do not supersede the separate-table storage design, so declaring the rows wrong can cause the still-open rail/table work to be dropped.

…nIndex tension resolved

Cross-session coordination with the r2il-machine-semantic-contract-v1 owner
session. Three answers landed, plus one methodological finding earned in the
verification pass.

1. D-RLR-4 RE-SCOPED, not retired — at the owner session's explicit request.
The storage half ("how does a session store R2IL") is answered by that plan's
§4, now tracked as D-R2IL-1 via lance-graph #1155; my §E was a thinner
independent restatement and now defers to it. What survives is the half §4
never touches and that just went live: what does the lance-graph-java membrane
consume, now that the 0x87..0x8B loco band is retracted and
ogar_loco::TERNLOG (FnIndex(0x86)) is minted-but-unconsumed. Live context is
lgj #70, which blocks the BELNAP_JOIN mint.

2. The §C/§D vs §4-R4 tension flagged in #1152's §F.6 is RESOLVED — no
conflict. R4's target is one-FnIndex-per-macro, which would burn slot space,
never FnIndex as addressing. ogar_loco::TERNLOG proves it concretely: one
FnIndex whose call value byte is the 8-bit truth table, so a single address
covers all 256 combinators (ogar-loco/src/lib.rs:607, vocabulary.rs:92-98).
Palette-as-vocabulary and FnIndex-as-address in one shipped symbol. The §C/§D
verdict stands unchanged.

3. Board rows for the r2il plan were filed by its owner (#1155, D-R2IL-1..5)
rather than by me — correctly, since it is their plan. Root cause was worse
than missing rows: the plan carried no D-ids at all, so STATUS_BOARD had
nothing to hold.

Also: the cross-repo citation audit that session recommended was run against
this plan's §C. All eleven cited symbols are PRESENT at 5e2cb31; the
September retraction stranded none of them.

New EPIPHANIES entry E-A-CROSS-REPO-SYMBOL-GREP-IS-ONLY-AS-FRESH-AS-THE-SIBLING-CHECKOUT-1
sharpens their rule with the precondition it needs. Following their advice I
grepped for TERNLOG and got zero hits in both trees — and nearly wrote up that
a peer's central claim failed verification. The OGAR checkout was 10 commits
behind; after fetching, every one of their claims verified exactly. A
cross-repo symbol grep answers "is this in the tree I have", never "does this
exist". Fetch first, then grep, then read the hit's surroundings.

Board writes post-checked per the never-truncate law (EPIPHANIES 25610->25671);
supersession index regenerated after the board writes and verified current.
