doctrine: T1 has TWO sibling algebras — syntax vs execution, not selection vs scoring (D-BBB-NARS-1) - #1222
Conversation
…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.

…ds, its indexes did not A compliance audit of #1222 against the operator ruling it encodes, not a re-litigation: the spec froze D-BBB-NARS-1 as not open, and VIOLATES required file:line evidence that the landed text CONTRADICTS the ruling. Nothing did. The ruling is unchanged. What the council found is that the PR widened the doctrine's CONTENT and left every INDEX of it stale, and that three sentences stated aspiration in the grammar of fact. Stale indexes, now fixed: - both warden cards' constitutional sentence ("your entire competence is the vocabulary of the two tiers you separate ... and nothing else") still named "T2 selection", so a card would decline the epistemic work its own new step 2b orders it to do; - bbb-warden's frontmatter description -- the text that decides whether the card FIRES AT ALL -- was never widened, though its sibling's was; - the T2 row's "May know" cell omitted the truth literal its own shape table says may cross; - the agent -> membrane map still listed three bbb-warden verdicts, so the doctrine did not know about the fourth this arc added; - the T2 -> T3 entropy ledger had no row for the epistemic leak class. Aspiration stated as fact, now labelled (new section "What is ruled vs what is coded"): - the epistemic column has NO structural gate, only review notes, against the doctrine's own "a membrane without a gate is prose"; F-BBB-NARS-1 cannot be exercised at all today. Ledger row L8 is marked OPEN, not CLOSED, and the gate that will hold it is named with its dependency; - revision/deduction/abduction/induction are coded only in the planner's nars_engine.rs and are ABSENT at the lgj-abi T1 membrane; - TruthU8 is the ruled TARGET: four truth types coexist and the engine that executes revision/deduction/abduction uses a different one, with no conversion path. Tracked as new D-BBB-NARS-4 (do not pre-build); - the Plan tree is illustrative -- plan_eval takes a flat AND/OR LgjOpDesc with two opcodes and no Truth opcode. Two factual errors carried past in a row this arc rewrote: Mask x WideFieldMask -> Mask (the shipped type is plain FieldMask; the wide one does not cross the ABI) and a bbb-warden sentence quoted as verbatim that was a paraphrase. Both corrected. Three missing citations added. Step 4 gained its silence half on the card rather than merely derivable. The reviewers caught the council itself: the consolidated draft cited the verdict-map row one line off while stamping it verified, which would have added the new verdict to the wrong warden; and it had imported a quotation from a private repository that a resolution would have carried into this public commit. Both resolved, not argued away. Gates: append_only_gate OK; citation_decay no new decay; supersession index regenerated LAST, byte-identical. The one .rs touch is a doc comment, and after the ndarray sibling was supplied it is verified by running, not asserted: clippy --all-targets -D warnings exit 0, tests 42/42 including doctests. cargo fmt --check on that crate stays red on pre-existing debt in 8 unrelated files -- the translator.rs hit is byte-identical to HEAD, so not mine, and reformatting them would balloon a doctrine PR. That crate is workspace-excluded with zero CI coverage either way. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_013S6AQs95K3rHymE3kAqZay

… one — fixed at BOTH sites
CodeRabbit (Major) on the EPIPHANIES entry: lines 35-39 stated in the present
tense that plan_eval resolves Truth.Revision and T1 executes it, while the same
entry's council addendum states the structural gate is absent and plan_eval has
no Truth opcode. The entry published an unavailable capability as a working
route and contradicted itself. The finding is correct.
Reworded as the target route, with the gating condition named: T3 will name
Truth.Revision and will not know how revision works -- that half is the ruling
and is permanent -- and once the structural gate exists and plan_eval carries a
Truth opcode (it carries {EQ_U32, GT_I32} today), T2 will resolve the name, T1
will execute, T0 will own the result. The membrane it lowers through is shipped;
the operation that would travel it is not. Original sentence quoted in place
rather than deleted, per the board's correction convention.
Fixed at BOTH sites, not just the flagged one. The identical present-tense claim
sat in membrane-tiers.md:96-98 and was not reported. Fixing only the reported
copy would reproduce precisely the index-staleness disease the 5+3 council
documented one commit earlier: a finding fixed at one site and left standing at
its twin.

… are five truth types, not four Reframed on an operator question: are the coexisting truth types distinct truths, or one truth at several precisions? Measured: all five carry the same two axes, (frequency, confidence). They are one kind of NARS truth at four precisions -- register u8, storage u16, compute f32 -- so the deliverable is "one canonical per tier, named lifts between tiers, no bare casts", not "converge onto TruthU8". The ruling (TruthU8 canonical at T0) is consistent with a ladder and is unchanged. The count was wrong: the council found four and missed lance-graph-planner/src/nars/truth.rs::TruthValue, the belief-arena type. Five, listed with sites. The genuinely distinct truths -- grammatical validity, causal-trajectory provenance -- are not on the ladder and enter it only by a named constructor (precedent: tesseract-rs sentence_nars_truth). Same axes does not prove same semantics: ndarray clamps confidence to [0, 0.9999], and the u16/u8 mappings have not been read side by side, so step 1 is an audit of the mappings, never a merge. Falsifier tightened: a bare `as` cast between any two of the five is an automatic fail. Losing text quoted in place. Docs only. Gates: append_only OK, no new citation decay, supersession index regenerated last.

…ssless" claimed nowhere until audited CodeRabbit (Major) on the reframe pushed ten minutes earlier, both findings correct and both mine: 1. The row said five representations form "four precisions". They share three scalar widths -- f32 (three of the five), u16, u8. The "four" was a leftover from the four-type count the same commit had just corrected to five. Now: five representations, three widths, not five kinds. 2. The falsifier promised a "lossless-upward lift per tier boundary" while prescribing f32 -> u16 and f32 -> u8 packing -- downward quantization, lossy by construction -- and in the same row said the mappings still need auditing. A blanket "lossless" before the audit that would prove it is the overclaim the council spent the day removing elsewhere. Now each direction carries its own grade: widening u8/u16 -> f32 is round-trip- exact but the f32 is a rounded rational, so not called lossless; packing is a named quantizer, lossy; dequantizing u16 -> f32 is the named inverse of the pack, not an identity. "Lossless" is claimed for no mapping until the audit proves that specific one, and an unaudited "lossless" is itself an automatic fail. Losing text quoted in place. Docs only. Gates: append_only OK, no new citation decay, supersession index regenerated last. Second time today a self-correction introduced a fresh error the reviewer caught (the first was the council's off-by-one row citation). Recorded rather than hidden.

… versioned LE schema, never a bare (f, c) pair Operator ruling, 2026-09-10, frozen verbatim: "Little-endian is the universal DTO layer of the ABI." The ABI carries the value; the LE DTO contract fixes the universal meaning of its positions; MUL asserts the epistemic kind; the (frequency, confidence) values are content; LE adds no evidence. Without a versioned canonical LE contract an ABI transports bits but cannot guarantee every reader assigns them the same epistemic meaning. The question was whether #1222 used "typed NARS syntax" strongly enough. It did not: the shape table let TruthLiteral(192, 217) cross "as itself" while retiring TruthU8 as "the wire form". A bare pair expresses a degree, not a kind. Sharpened, not reversed -- TruthU8 stays the canonical T0 substrate representation; what crosses is now defined: typed syntax SHALL be bound to a versioned DTO schema with canonical little-endian layout, or to an opaque typed handle whose registry binds the same kind and schema. For two u8s the contract is the ordered byte sequence [frequency, confidence]; for a packed carrier such as CausalEdge64 the whole integer-to-byte mapping is explicitly LE. Falsifier F-BBB-NARS-2 (LE) added, plus the evidence distinction: an identical wire image repeated is propagation, not independent evidence. Measured before writing, no code changed. A versioned LE contract EXISTS for the SoA envelope (ENVELOPE_LAYOUT_VERSION = 2, verify_layout, le-contract.md S3b) and NO truth type rides it: TruthU8 has no repr(C), no version, no codec; CausalEdge64 is repr(transparent) u64 with register-defined bit positions and zero endian conversions, host-native at every crossing, its v1/v2 layouts a compile-time feature invisible in the bytes; MUL never sees bytes (SituationInput is typed f64s; revise_fast takes bare u8s and ignores confidence). lgj already declares byte order as ABI shape (LgjLaneDesc.endianness, the LGJ_MAGIC probe, abi.md:1224) but carries no truth DTO. So: CODED for the envelope, ABSENT for truth, RULED now, DEFINED by D-BBB-NARS-2 when it lands. Three corrections carried with it: bbb-warden's sanctioned delegation returned a COMPUTED TruthLiteral -- a bare pair crossing back, blessing the exact leak -- and now returns an opaque typed handle; translator.rs paired confidence_u8 with the i4 mantissa, which is the InferenceType (provenance grammar, bits 46-49), not half of the truth -- corrected to frequency_u8 + confidence_u8 (bits 24-31, 32-39); and every index of the amended sentence (shape table, both warden cards, ledger L8, ruled-vs-coded S4, the D-BBB-NARS-1/-2/-3 status cells) moved in this one commit so the stale-index defect the council closed is not reopened. Deliberately not built: no DTO struct, opcode, ABI symbol, G11 import, conversion, or Java. D-BBB-NARS-2/-3 stay Queued, do not pre-build. The one .rs touch is a doc comment.

…ygiene gaps Real code fix (crates/lance-graph-planner/src/cache/nars_engine.rs): NarsTables::deduce_fast returned the deduction table's packed byte as if it were the real NARS deduction confidence, but that byte is f_out doubling as a conservative UPPER BOUND (per tables.rs's own doc comment) — not c = f*c1*c2, the formula this same file's Inference::Deduction arm already implements. Consequence: two premises with ZERO evidential confidence but max frequency (f1=f2=255, c1=c2=0) reported confidence 255 — maximally confident from maximally unevidenced premises. Fixed: deduce_fast now takes c1/c2 and computes the real deduction confidence. Added a two-sided regression test (zero confidence -> zero output; full confidence -> unchanged upper bound) and updated the one existing call site. 23/23 planner cache::nars_engine tests green, 433/433 full lib suite green, fmt clean. Board-hygiene fixes, all verified against current source before editing (the review ran against commit 85af677, two commits behind HEAD, so several findings were checked for staleness first): - EPIPHANIES.md: (1) the ReasoningBand writer census now states plainly that no shipped production code writes CausalTopology/ReasoningBand — every non-definition call site is an examples/*.rs probe or a #[test] fn, confirmed by direct grep across the tree; (2) removed a stray insertion into the already-merged (via #1222) 2026-09-07 entry that violated the Status/Confidence-only edit rule for settled entries and duplicated what the newer 2026-09-10 entry's own Status line already says — the entry is now byte-identical to origin/main again; (3) added a precision note to the "CE64 is the defining LE" ruling distinguishing the ruling (a status declaration) from a claim that CE64 has an explicit LE codec (it does not — zero to_le_bytes/from_le_bytes, unlike CausalEdgeV3), and restating the real version-gate risk under the v1-compat feature opt-out. - INTEGRATION_PLANS.md, LATEST_STATE.md: both still described `contract::assertion_wire` as built and "In PR (#1223)" — that module was deleted as fabrication by commit 2c66c01 ("strip the fabrications"), which corrected EPIPHANIES.md and STATUS_BOARD.md but missed these two files. Prepended matching retraction entries (append-only convention preserved — both files only grew, verified via append_only_gate.py). - membrane-tiers.md: two stale sub-sections corrected in place (matching this file's own established "⊘ superseded" annotation style, used throughout the same document) — the "D-BBB-NARS-2 is now BUILT" claim and the "LE DTO contract... ABSENT for truth... defined by D-BBB-NARS-2 when it lands" claim, both superseded by the same fabrication-strip ruling. - nan-ci-mode-v1.md (the plan itself, 3 genuine gaps found and closed, 1 already resolved by the prior council commit, 1 declined as by-design): - §4.1's certification criterion required only "zero canary reads" on a wire, which a dead/unexercised consumer path also reports — added the missing "observed to execute at least once" clause. - §3.3's Design 1 (POISON-FILL) writes a canary before the read-side observer runs, in tension with N1's literal wording; named the concrete risk (a CI-poisoned object that gets serialized/persisted leaks canary bytes) and the two candidate resolutions, left open for an operator decision before D-NCI-1, per this plan's own established practice of flagging rather than unilaterally resolving frozen-decision boundaries. - §4.5's counterfactual probe treated every stored `0` as absent without the canary/sidecar qualification Design 1 itself requires; scoped the probe explicitly to CI-instrumented objects, never persisted corpora. - §9.1's already-present typed disposition table (BandPresence::Absent / EdgeProvenance::Unknown / BandDeclarations::get->None) already satisfies the "define a typed absence reason before D-NCI-1" finding — added by the prior council commit (e8099ea), after the commit CodeRabbit reviewed. - SUPERSESSION-INDEX.md's "28 vs 25" GateDecision count is by design (Table 1's "named in plans" counts all mentions; Table 2/"blind plans" deliberately excludes plans already showing awareness markers per the generator's AWARE regex) — not touched; explained in the PR reply. Gates run: append_only_gate.py (all 9 protected files, none shrank), citation_decay.py --since cd24951 (0 new decay), plan_dids.py on the added plan (carries a D-id), supersession_index.py regenerated last (byte-identical — no structural inputs changed).

…l audit Requested review: diff the whole PR against origin/main (merge-base cd24951, i.e. #1222) and account for every line that is not a pure addition. 25 lines were removed across 8 files; all but two are legitimate (bug fixes to code #1222 shipped, well-documented in-place corrections in non-gated agent cards, or a regenerated file). Two were real: 1. STATUS_BOARD.md, row D-BBB-NARS-2's status cell replaced its #1222 text ("Queued — gates on a consumer actually needing it; do not pre-build") outright, with no verbatim preservation anywhere in the new cell — the only one of the table's four rows that didn't follow its own sibling rows' pattern of keeping the old text as a prefix and appending the correction. append_only_gate.py (line-count-only) could not catch this because the row count didn't change. Restored the original phrase as a prefix, matching D-BBB-NARS-1/-3/-4's own style. 2. membrane-tiers.md deleted the heading "### The G11 widening rule: one scalpel cut, never the cupboard" outright. Its body paragraph survived intact ~150 lines later in the file, but sits headless between two unrelated sections. Restored the heading immediately above its body. Both are prose-only; no code, no ontology, no ruling changed. Gates: append_only_gate.py OK (STATUS_BOARD.md line count unchanged, as expected for an in-place cell fix), citation_decay.py 0 new decay, supersession_index.py regenerated (byte-identical, neither file feeds it).

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
What lands
.claude/knowledge/membrane-tiers.md— T1 row (two sibling algebras), T2 row renamed, new § with the lowering diagram, the plan-language rule, theTruthU8shape table, the G11 rule, and both D-/F- statements quoted..claude/board/EPIPHANIES.md—E-T1-HAS-TWO-SIBLING-ALGEBRAS-THE-AXIS-IS-SYNTAX-VS-EXECUTION-1(operator ruling, BINDING)..claude/board/STATUS_BOARD.md— arcbbb-nars-lowering, D-BBB-NARS-1 (Ruled) / -2 (queued, do not pre-build) / -3 (queued)..claude/agents/bbb-warden.md— the epistemic column, and a fourth verdict ARITHMETIC-SURFACE for a signature that lets T3 implement/inspect/iterate/reconstruct a T1 algebra rather than name it.The BBB does not move. T3 names / T2 opaque behavior handles / T1 algebra (population ‖ epistemic) / T0 state. No VSA internals, no RoleKey, no NARS arithmetic, no byte positions, no truth arrays, no Java compute path. Only names and capabilities. The widening makes the doctrine more general, not more permissive.

⊕ 2026-09-10 — hardened by a 5+3 council before merge (
b2fcd43)Everything above is the original submission and is left standing; this section
records what a spec-first 5+3 council changed. It was a compliance audit of the
ruling, not a re-litigation — the spec froze
D-BBB-NARS-1as not open, and aVIOLATESrequired file:line evidence that the landed text contradicts it.Nothing did. The ruling is unchanged.
What it found: the PR widened the doctrine's content and left every index
of it stale, and three sentences stated aspiration in the grammar of fact.
Stale indexes — six sites, three savants converging independently. Both warden
cards' constitutional sentence ("your entire competence is the vocabulary of the
two tiers you separate … and nothing else") still said
T2 selection, so a cardwould decline the epistemic work its own new step 2b orders it to do;
bbb-warden'sfrontmatter
description— the text deciding whether it fires at all — was neverwidened though its sibling's was; the T2 row's
May knowcell omitted the truthliteral its own shape table says may cross; the agent→membrane map still listed three
bbb-wardenverdicts, so the doctrine did not know about the fourth this arc added;the T2→T3 entropy ledger had no row for the epistemic leak class.
Aspiration as fact — now labelled, in a new § "What is ruled vs what is coded":
the epistemic column has no structural gate, only review notes, against the
doctrine's own "a membrane without a gate is prose" (ledger row L8 is marked
OPEN, not CLOSED);
revision/deduction/abduction/inductionare coded onlyin the planner's
nars_engine.rs:194-207and are ABSENT at the lgj-abi T1membrane;
TruthU8is the ruled TARGET — four truth types coexist and the enginethat executes those ops uses
ndarray::hpc::nars::NarsTruth, with no conversion path(new
D-BBB-NARS-4, do not pre-build); and thePlantree is illustrative,since
plan_evaltakes a flat AND/ORLgjOpDescwith{EQ_U32, GT_I32}and no Truthopcode.
Two factual errors were carried past in a row this PR rewrote:
Mask × WideFieldMask → Mask— the shipped type is plainFieldMask; the wide one does notcross the ABI (
fixture.rs:1-6calls wiring it "a later slice") — and abbb-wardensentence presented in quotation marks that was a paraphrase. Both fixed,plus three missing citations and the silence half for step 4 on the card.
The reviewers caught the council itself. The consolidated draft cited the
verdict-map row one line off while stamping it verified, which would have added
the new verdict to the wrong warden; and it had imported a quotation from a private
repository that a resolution would have carried into this public commit. Both
resolved, not argued away.
Correction to this body
The Gates line above says "no Rust changed, no code changed." That is no longer
true: the council's F-B fix touches one
.rsfile,lance-graph-arm-discovery/src/ translator.rs, whose doc comment still calledTruthU8"the canonical, float-freewire form" — the exact phrasing this ruling deprecates, at its only referent in the
repo, left uncited and unchanged. The change is doc-comment-only (every changed
line is a
///) and is verified by running, not asserted:cargo clippy --all-targets -- -D warningsexit 0,cargo test42/42 including doctests.cargo fmt --checkon that crate stays red on pre-existing debt (33 sites, 8files); the one
translator.rshit is byte-identical toHEAD, so not mine, andreformatting eight unrelated files would balloon a doctrine PR. The crate is
workspace-excluded with zero CI coverage either way — which is itself a
council finding, since it means the gate had to be invoked with
--manifest-path.Board gates:
