…on (D-BBB-NARS-1)
A three-agent audit of the T2/T3 barrier measured NARS truth arithmetic as
absent from the Java side — repo-wide grep of lance-graph-java at `8720d1d`
returns 3 hits, all prose, all in one unshipped plan; `lance_graph_contract::nars`
is not in the G11 allowlist; the sibling callcenter membrane states it outright
("no VSA / RoleKey / NarsTruth crosses the membrane"). The measurement is right.
The conclusion drawn from it — "NARS is off the ladder entirely; the ladder is
selection-shaped and has no tier for scoring" — is wrong twice, and the operator
ruled it so.
**The axis was wrong.** Not selection vs scoring: **syntax vs execution**, which
is the axis every other tier is already built on. `where()` is T2 because Java
owns the NAME and T1 owns the op; nothing in that reasoning is specific to
populations.
**The remedy was wrong.** The audit proposed a new bulk verb family
(`lgj_score_*`) returning a lane instead of a mask. Rejected — it grows a second
semantic API beside `plan_eval` and ends as `where()/hop()/score()/
nars_revision()/…`, with Java knowing progressively more about the behavior
graph. The membrane starts growing little computational fingers. `lgj_plan_eval`
exists precisely so a whole behavioral expression crosses ONCE; NARS becomes
another named plan operation or it is nothing.
**The ruling.** No sixth tier. T1 was described too narrowly: it holds two
sibling primitive algebras — population (`mask`, `ternlog`, `eq → mask`,
`popcount`) and epistemic (`TruthU8`, revision, deduction, abduction). Both are
primitive behavior. T2 may name either, may hand-compose neither; T3 may express
intent in either. Every existing rule carries over unchanged — HAND-COMPOSED
covers a T2 spelling `revision` out of smaller truth ops exactly as it covers
the two-AND spelling of `AND3`. The T2 row is renamed *selection* → *behavior*,
which is what it always was.
**A wording correction the ruling forces.** `TruthU8` had been called "the
canonical wire form" — two claims conflated. It is canonical at T0. What crosses
is decided separately and BY SHAPE: a truth LITERAL (`TruthLiteral(192, 217)`)
is syntax the caller supplies and may cross; a truth POPULATION
(`[TruthU8; 65536]`) never crosses — it becomes `TruthLaneId(u64)`. The same
rule masks already have, second column. It lands on the measured Valhalla cliff
exactly: flattening stops at an 8-byte payload (VM-confirmed), so the handle
flattens and the array could never. Valhalla carries the noun, Panama carries
the verb, lance-graph owns the reality.
**G11 widens by one scalpel cut, never the cupboard.** Do not admit
`lance_graph_contract::nars` because it exists; if it carries arithmetic beside
POD types, split a syntax/vocabulary contract out first and admit only that —
one commit, all three spellings of `ALLOWED`.
Landed: `membrane-tiers.md` (T1/T2 rows, new § with the lowering diagram, the
plan-language rule, the TruthU8 shape table, the G11 rule, D-BBB-NARS-1 +
F-BBB-NARS-1 quoted); EPIPHANIES entry; STATUS_BOARD arc D-BBB-NARS-1..3;
`bbb-warden` gains the epistemic column and a fourth verdict, ARITHMETIC-SURFACE.
The BBB does not move. T3 names / T2 opaque behavior handles / T1 algebra
(population ‖ epistemic) / T0 state. The widening makes the doctrine more
general, not more permissive.
Gates: append-only OK (9 files), citation-decay 0 new, supersession index
current. No code changed.

…s that did not cover it Three findings, one class — I wrote rules that advertised enforcement which did not exist. That is the same defect this repo's own history records as the G11 fence being prose until 2026-09-03, and the same one PR #1221 carries a storno about. Found three times in one commit; fixed in this one. **1. `kernel-membrane-warden` did not cover truth composition** (Codex P2, `membrane-tiers.md:64`). The new § claimed its HAND-COMPOSED verdict "covers a T2 that spells `revision` out of smaller truth ops exactly as it covers `AND3` as two `mask_and`s." Verified at the source: the card's trigger names `mask_*`/`eq_*_to_mask`/`ternlog` and "T2 code that composes mask primitives"; method step 2 reads "for every mask/compare/scatter". A T2 hand-composing `revision` walked straight through the gate the paragraph invoked. Fixed by making the claim TRUE, not by softening it: the trigger now names both sibling algebras, and **method step 2b** asks the same question of truth operations — T2 arithmetic over `frequency`/`confidence`, a `w/(w+1)` discount, a min/max over two truths, a revision hand-rolled from component `and`/`or` are all HAND-COMPOSED; reading a `TruthU8`'s two bytes apart to recombine them is GEOMETRY-LEAK, because the byte split is T0's. **2. The canonical table contradicted its own shape rule** (Codex P2, `membrane-tiers.md:22`). The T1 row said it crosses up as "a truth lane" while the shape table twelve lines down says a truth POPULATION never crosses and becomes `TruthLaneId`. Both statements standing made a raw `[TruthU8]` boundary defensible FROM THE CANONICAL TABLE — the worst place for an ambiguity to live. Now: "a truth lane DESCRIPTOR (`TruthLaneId`) — never the population." **3. `bbb-warden`'s method could not reach its own new verdict** (Codex P2, `bbb-warden.md:79`). ARITHMETIC-SURFACE blocks a signature that lets T3 implement, inspect, iterate or reconstruct a T1 algebra — but steps 1-3 enumerate signatures and classify parameter/return SHAPES only. A public helper with a perfectly legal `TruthLiteral` signature computing revision in its BODY passes every step while doing exactly what `F-BBB-NARS-1` forbids; so does a body-only change to a method that already existed. New **method step 4**: read BODIES (arithmetic over frequency/confidence, a loop over a lane, a local recombination of a handle's parts) and read what a newly-G11-admitted module EXPORTS (a POD type is syntax; a function computing a truth FROM truths is an implementation surface, and admitting the module admits it). The falsifier, not the signature list, is what the reviewer reasons against. The doctrine paragraph now carries the correction inline rather than quietly becoming true, because the general rule is worth more than the three fixes: **a doctrine sentence that names a gate must cite the step that makes it true.** Gates: append-only OK (9 files), citation-decay 0 new, supersession index current.

…G arc #1221 merged (`f29200f`) and put this PR into conflict. One real conflict, in `STATUS_BOARD.md`: both sides prepend a new arc block at the top of a newest-first file. Resolved by keeping both, ordered by recency — the `bbb-nars-lowering` arc (unmerged, this PR) above `spog-alpha-channel-v1` (merged 06:31). `EPIPHANIES.md` auto-merged with the T1-sibling-algebras ruling on top; `membrane-tiers.md` did not conflict at all, because #1221's copy was byte-identical to `main`'s after the AND3 restore. Confirmed on the new `main` rather than assumed: the storno commit `2dda2ff` is in its history, and `membrane-tiers.md:37` reads "`exports.rs` names `kernels::ternlog::AND3`" — so the doctrine that ships is the corrected one. The stale claim survives only in #1221's merged PR BODY, which is prose in the arc record, not a statement the tree makes. This branch's own D-SPG edits from the earlier integration-update pass are superseded by #1221's newer, measured rows (D-SPG-2/3 pushed for real, D-SPG-5 split, D-SPG-8 shipped); their version wins, as it should. Gates against the new base: append-only OK (9 files), citation-decay 0 new, supersession index current. No code changed.

Operator ruling on the T2/T3 blood-brain barrier, plus the doctrine change it forces. No code.
What was measured, and what was concluded from it
A three-agent audit mapped the barrier across
lance-graph,OGAR,lance-graph-java(@8720d1d) andr2sleigh(@99d2553). On NARS it found: repo-wide grep of lgj returns 3 hits, all prose, all in one unshipped plan;lance_graph_contract::narsis not in the G11 allowlist; the sibling callcenter membrane says it outright — "no VSA / RoleKey / NarsTruth crosses the membrane."The measurement is right. The conclusion — "NARS is off the ladder entirely; the ladder is selection-shaped and has no tier for scoring" — is wrong twice.
The axis was wrong. Not selection vs scoring: syntax vs execution, which is the axis every other tier is already built on.
where()is T2 because Java owns the NAME and T1 owns the op; nothing in that reasoning is specific to populations.The remedy was wrong. The audit proposed a new bulk verb family —
lgj_score_*, ∝n_rows, returning a lane instead of a mask. Rejected. It grows a second semantic API besideplan_eval, and the end state is predictable:where(),hop(),score(),nars_revision(),nars_deduction(), … with Java knowing progressively more about the behavior graph. The membrane starts growing little computational fingers.The ruling
No sixth tier. T1 was described too narrowly.
Both are primitive behavior. T2 may name either. T2 may not hand-compose either. T3 may express intent in either. Every existing rule carries over unchanged —
kernel-membrane-warden's HAND-COMPOSED verdict covers a T2 spellingrevisionout of smaller truth ops exactly as it covers the two-AND spelling ofAND3. The T2 row is renamed selection → behavior, which is what it always was.NARS lowers through the membrane that already exists:
T3 may say
Truth.Revision(lhs_handle, rhs_handle). It may not know how revision works. Extend the plan language, not the ABI surface —lgj_plan_evalexists precisely so a whole behavioral expression crosses once.A wording correction the ruling forces
TruthU8had been called "the canonical wire form." Two different claims were conflated. It is canonical at T0. What crosses is decided separately, and by shape:TruthLiteral(192, 217)[TruthU8; 65536]TruthLaneId(u64)Same rule
bbb-wardenalready applies to masks ("along[]of selected ids is still a materialised population"), second column. And it lands on the measured Valhalla cliff exactly: flattening stops at an 8-byte payload (VM-confirmed,valhalla-lab/docs/three-truths.md), so the handle flattens and a truth array could never. Valhalla carries the noun; Panama carries the verb; lance-graph owns the reality.G11: one scalpel cut, never the cupboard
Do not widen the fence to
lance_graph_contract::narsmerely because it exists. If that module carries arithmetic beside POD types, split a syntax/vocabulary contract out first and admit only that — one commit, all three placesALLOWEDis spelled. (lgj's own history has the cautionary case: the fence was prose until 2026-09-03,ISS-LGJ-G11-FENCE-WAS-PROSE.)The ruling and its falsifier
