From 581f646a0421b0e358c17c2d4dc6955fd3406bc0 Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 11 Oct 2026 15:17:54 +0000 Subject: [PATCH 1/2] Research recovery reports: CE64 / Gadamer / Neutrino (docs only) Commit the session research reports so they survive the container: consolidated ledger (closed C1-C14, excluded X1-X7, open O1-O35, dots D1-D7), Gadamer x Pearl x ablation research, neutrino x Morton-Moore recovery, A-G recovery with B1-B5 substrate reports, session balance, council drafts, and a note on arXiv 2604.18873. No code, contract, plan-status or verdict change. Open items stay OPEN. One board entry added; entries index regenerated. The model-identifying trailer is omitted per this repo's "no model identifier in any committed artifact" rule (ledger item O7).

With mask-risc's 256-word tile (=4^4, Morton-aligned) a source NOT confined to the tile loses carries — so a tiled shift needs the neighbour tile's edge words. Today nobody does this; the hex probe works on a node span where `state ⊆ tile` by construction. +- mask-risc cannot express any of it: no shift MaskOp (ABSENT, §2). A consumer would call ndarray directly, or precompute S and hand it to mask-risc as a resident `Plane`, where `Count{Ternlog(AND2) over two planes}` lowers to the fused `Ternlog` fold (no scratch). +- Fused shift+AND+popcount: closed search over ND simd_masking_ops.rs (`shift` hits only the Morton section :5174-5450 and unrelated comments) and LG mask-risc/src → **ABSENT**. `mask_ternlog_popcount` fuses Boolean+count but takes three aligned slices; it cannot permute bits. + +**Precisely what is missing:** a word-level `Σ_w popcount(M[w] ∧ shift_Δ(M)[w])` that never writes the shifted plane. For one-cell Δ, `shift(M)[w] = interior_dir(M[w]) | carry_dir(M[nb⁻¹(w)])`, so the fused value is computable per word from M[w] and ONE neighbour word — no dst. That is **a new kernel** (or a new facade word, e.g. a `mask_shift_morton_and_popcount`), not a lowering: it cannot be lowered over existing words without materialising S, because no existing word exposes the interior permutation or carry without writing dst. Diagonals/larger Δ compose interior permutations (still per-word + bounded neighbour words) — the kernel would need a Δ parameter beyond `MortonDir`. At the mask-risc layer it would additionally need a new MaskOp/Terminal and a tiled halo (neighbour-tile edge words) to respect the tiled law.

No Moore-8 instance found. +2. **Displacement-pair autocorrelation** C(Δ) = popcount(M ∧ shift(M,Δ)) = #ordered pairs (p, p+Δ) both set; Σ_{Δ∈R} C(Δ) counts neighbour PAIRS with multiplicity (= 2× undirected edges among set cells), ≠ U. Translation-symmetric: C(Δ)=C(−Δ) in the interior (edges break it: no wrap). **No code computes it** (closed: mask-risc src, ND simd_masking_ops; examples searched for autocorrel → only unrelated hits). Today: shift (§5) + `mask_ternlog_popcount::`. +3. **Hamming distance** H(A,B) = popcount(A ⊕ B) between two planes (no displacement). Code: `mask_xor`+`popcount_batch_u64`, or `mask_ternlog_popcount` with an XOR immediate (fused); byte form `ndarray::bitwise::hamming_distance_raw` (ND bitwise.rs:192). Note H(M, shift(M,Δ)) = |M| + |shift(M,Δ)| − 2C(Δ) — related to (2) only through that identity, and |shift(M,Δ)| ≠ |M| at edges. +4. **Weighted measurement** Σ_{p∈mask} w(p): a value-lane reduction under a mask (A2: the mask selects, the weight is a separate lane). Code: `masked_sum_i32` (ND :814) / mask-risc `Terminal::MaskedSumI32`, group variants; per-offset weights as ring templates `Σ_k w_k·popcount(win∧ring_k)` or bit-sliced planes (mexhat arms E/F). +5. **Centre-surround decision** sign/threshold of S(c) = Σ_p w(|p−c|²) with a signed (DoG) kernel, e.g. S(c) ≥ T. A weighted measurement (4) with positive centre / negative surround, read as a DECISION, which admits early exit with exact bounds.

But: (a) the lattice is **lower-tail only** ("lower distance is stronger", `shade` counts thresholds strictly above x) — a "high count is significant" observable must be reflected (`8k − count`) or offset to unsigned; (b) `for_width` is a **Hamming-specific binomial prior** (μ = bits/2) — for ring counts use `calibrate` or `from_params` with a prior derived for the count (e.g. Binomial(8k, p) for a Bernoulli(p) field); (c) one floor = one global distribution. A **local** learning threshold (per neighbourhood, per trie node) would need one `RollingFloor` per group — feasible but each carries a 1000-sample reservoir `Vec`, so 1024 nodes ≈ 4 MB of reservoir, and every checkpoint sorts. The mergeable part (moments) shards; the reservoir does not. +- **`Cascade::calibrate` / `observe` / `observe_batch` / `ShiftAlert`** — f64 Welford + μ+3σ upper threshold + 2σ drift alert on any u32 stream. Usable as a quick global drift detector for a spatial statistic; but its threshold is "accept below μ+3σ", the Hamming-retrieval polarity. +- **`Cascade::expose` → `Band`** — bucket assignment by fixed fractions (¼,½,¾,1) of one threshold. Reusable as a 5-way bucketing of any u32, but those fractions have no statistical meaning for a ring count; the σ-lattice (`RollingFloor::shade`) is the principled bucketing. +- **Bounded keyed folds with a spatial key**: the `_pair` / `_via` addressing takes any u32 key lane; using the Morton trie-node id (`morton_index >> (2·L)`) as the key gives per-node local statistics in one pass — the key lane must be materialized (or computed per call); there is no built-in "group = trie node of row i" address. + +### 8.3 NOT usable (approximate, or a different problem) +- **`Cascade::query`, `cascade::PackedDatabase::cascade_query`** — approximate retrieval (Stroke 1 estimate prune; packed Stroke 2 is also an estimate prune). Wrong problem (vector NN, not lattice adjacency) and not an oracle. Do not use as ground truth or as a spatial neighbour finder. +- **The 128-candidate preheating** — σ from the **first 128 rows in storage order**: on a Morton field that is one 16×8-ish sub-block, a spatially correlated sample, not a population sample. It would estimate local σ of one corner, not the field. +- **Stroke split / `PackedDatabase` (both stroke packers)** — they split the *bytes of one vector*; a spatial field has no "vector prefix" whose popcount scales to the whole. The PR #354 pin is a layout fact about 2048-byte fingerprints and says nothing about spatial data. +- **`query_candidates`** — trusts caller distances unverified when > 0. +- **`adaptive_resolution`** — hand constants, entropy/CV of a query vector. +- **`Statistics::percentile`** for gates — interpolating f64 rule; mixing it with `quantile_of_sorted` would give two quantile definitions in one experiment. + +### 8.4 What is MISSING for the spatial case (named precisely) +1. **A per-cell neighbour COUNT (ring count) primitive.** Everything in-tree counts a whole field (`popcount_batch_u64`) or per mask-selected row into keyed buckets (`group_walk`, scalar, cost ∝ selected rows). There is no op that produces, for every cell, the integer number of set Moore neighbours. The obvious realization — a **bit-sliced carry-save adder** over the 8 shifted planes using `mask_ternlog::` (sum) and `::` (carry), giving ⌈log2(8k+1)⌉ count bit-planes — is constructible from public API today (ABSENT as a named, tested primitive). The closest thing ever written, `bit_sliced_weighted_count`, was a different shape (a weighted popcount of ONE window, signed planes) and was **withdrawn** in PR #354 with an explicit ruling against signed masks/geometric windows in this facade (blackboard.md:4). +2. **Radius-k rings / Chebyshev neighbourhoods beyond 1** — only unit axis shifts exist; radius k = repeated shifts (k·4 axis + diagonal compositions), each a full pass; no ring-of-radius-k op, no wrap/torus mode. +3. **A Moore (8-neighbour) helper** — `MortonDir` is the 4 axis moves; the module doc and the hex probe compose the 2 hex diagonals; the other 2 (Moore) diagonals are equally compositional but not provided. +4. **An upper-tail σ-lattice / two-sided threshold** in `RollingFloor` (or the reflect convention, documented) — needed if "centre significantly above surround" is the event. +5. **Per-group (local) rolling floors** — a mergeable, reservoir-free local threshold. Moments per group already exist (`PowerSums` keyed folds); what is missing is a `SigmaLevel`→threshold read straight from a `PowerSums` (Gaussian frame) so local learning thresholds need no per-group reservoir. +6. **Projection helpers from `CrossPowerSums` to covariance / r / slope** (and a Moran's-I-style normalization) — the sums are exact and present; the division step is left to every caller. +7. **A spatially unbiased sampler** for calibration (Morton-strided or hashed-index sampling) to replace "first 128 rows" warm-up if any warm-up is wanted. +Before building 1–3, note the standing ruling (blackboard.md:4): a 256×256 tile is a *palette256 × palette256 address* answered by 256×256 distance/compose tables, **not** by geometric windows. A Moore/Morton geometric experiment should either justify itself against that ruling or live in an example/probe (as `hex_tenant_mq_probe.rs` does), not in the facade. diff --git a/.claude/research/2026-10-recovery/B4-statistics-mapping.md b/.claude/research/2026-10-recovery/B4-statistics-mapping.md new file mode 100644 index 000000000..757de9a53 --- /dev/null +++ b/.claude/research/2026-10-recovery/B4-statistics-mapping.md @@ -0,0 +1,256 @@ +# B4 — Statistics mapping: `shared/lab.rs` vs the canonical owners (jc, ndarray) + +Read-only research, 2026-10-10.

Empirical point estimate, no interval; bins pool 16 blocks whose predictions are sequentially dependent (same learner), so any interval on ECE would need a dependence-aware method (block bootstrap over seeds), not IID. | `jc::calibration::{ece, reliability_bins}`; name it `calibration`, not `reliability`. | +| `fn brier(pairs: &[(f64, bool)]) -> f64` (:202) | C | **4** | none; trivially correct; empty input returns 0.0 (divides by `len().max(1)`) — a silent value where jc's contract would return `None`. | `jc::calibration::brier -> Option`. | +| `fn report(pr, r, rejected) -> String` (:211) | — | **4** (presentation) | Labels every line "(statistical)". | stays in the probe (formatting is not math). | +| `fn normal(u) -> f64` (:228, private) | sampling | **3** | Same Box–Muller exists three times in ndarray, all **private** (`randomized_signature.rs:365`, `compression_curves.rs:35`, `clam.rs:2813`).

Two items are class (3) (`paired` +vs `jc::stats::t_test_paired`; private Box–Muller vs ndarray's three private +copies). Everything else is class (4): jc has point estimates and classical +p-values but no exact/permutation test, no CI, no t-quantile, no multiple-testing +correction, no pre-registration/verdict, no calibration (ECE/Brier), no samplers. + +### Where each dependence model applies + +- **Jirak (weak dependence)** applies where the *unit of inference is a sum over + weakly dependent bits or codebook-shared components*: Hamming distances on 16,384-bit + fingerprints, role-key-overlapping slices, CAM-PQ-quantised codes, XOR-bundle + accumulation (`jirak.rs:7-10`). A σ-threshold or p-value **on those sums** must not use + IID Berry–Esseen or the classical t (`stats.rs:44-53`). +- **Matched-block paired design over independent seeds** — the lab — is a different + regime. The unit of inference is the **block** (one seed / one puzzle), and the + statistic is the per-block difference `d_i`. Dependence *inside* a block (300 games of + one sequentially-learning agent; bit-level dependence of any fingerprints the agent + uses) is absorbed into `d_i` and never enters the test. What the exact sign-flip p + needs is: (a) `d_1..d_16` mutually independent — met by construction (distinct + seeds 2001–2016 / 4001–4016; distinct puzzles from seed 0x1AB5EED), and (b) under H0 + each `d_i` is **symmetric about 0** (sign-exchangeable). (b) is an *assumption*, not + a consequence of randomisation: arms were not randomly assigned within a block, both + arms run the same seed deterministically. It holds under the sharp null "the config + change has no effect on the outcome distribution of a block", which is what H0 says. + Given (a)+(b) the p-value is exact; Jirak is irrelevant at this level. +- **The t-interval** (`lo`,`hi`) additionally assumes approximately normal `d_i`; with + n = 16 that is a real assumption (game-score windows are bounded averages, folds/step + is heavy-tailed). The lab itself says so (lab.rs:7-9). +- **ECE** pools predictions across steps of one learner: those are serially dependent, + so ECE is correctly labelled *empirical*; no interval may be attached using IID + formulas. A block bootstrap over seeds is the dependence-honest interval. + +--- + +## Deliverable 3 — every verdict the lab produced, and whether the canonical owner changes it + +Sources: board entries (CLAIMED-IN-DOC numbers; the probes print them, they are not +asserted in tests) and the call sites (VERIFIED-IN-CODE). Every family: n = 16 matched +blocks, Holm α = 0.05, decided by `lab::paired` → `lab::holm` → `lab::verdict` +(`moore_nars_gomoku_probe.rs:1570-1584`, `1689-1702`; `crossword_crossing_care_probe.rs:1555-1568`). + +**Counterfactual method.** The canonical owner for a paired significance test is +`jc::stats::t_test_paired` (`stats.rs:1045`).

The flip is evidence that (a) H3 sits on the decision boundary +(board's own OPEN: "H3 needs more blocks"), and (b) a migration of lab.rs onto jc +must **carry the sign-flip test into jc**, not substitute jc's t-test — otherwise a +recorded verdict silently changes. + +--- + +## Findings worth acting on (ranked) + +1. **lab.rs is an ad-hoc statistics module in a probe**, against + E-JC-IS-THE-HOME-OF-ALL-CALIBRATED-MATH-1.

The u8 register is an implicit EXPONENTIAL-FORGETTING learner with an effective window of ~22 unit events, not the persistent learner. (So Arm B through CE64 F/C is closer to the falsified decay arm than to BASE.) +- 20 identical +7 echoes: u8 C reaches 244 just like 20 independent events — the register cannot tell them apart (matches gadamer_isa_revision.rs:265-271). + +### (c) Which operation connects them +- The learner's credit IS NARS revision in real arithmetic: with belief (f,c) ↔ (pos,neg), w = pos+neg, and an observation of frequency 1 (a>0) or 0 (a<0) with weight |a|/7, `truth::revision` yields w' = w + |a|/7, f' = (f·w + [a>0]·|a|/7)/w' — identical to `pos += a` / `neg -= a` at probe :911-915 (k = 1 on both sides).

So the SEMANTIC operation exists (`Opcode::Revision`, `CausalEdge64::revision`). +- What is broken is the CARRIER of that operation: u8 F/C (lossy, saturating, sign-flipping f), and NarsTables 16-bin c (adds confidence from c=0 weights, chain_confidence.rs:113-125). +- The EXACT connection available today is a masked grouped reduction over an event table (one row per credited step: key_id u32, recipe u32, pos_act i32/u8, neg_act i32/u8, plus provenance lanes): `GroupSumI32` (or `GroupReduce`/`GroupPowerSumsI32`) with `GroupKey::Pair{hi: key_id, lo: recipe, stride: 9}`, mask = "credited, learn on, not frozen". Exact for decay = 1.0, order-independent, mergeable (`merge_group_sink`), and bounded-u8 into Register0/Register1 group rows. +- The Moore shift (`mask_shift_morton`, plasticity probe) is NOT the connecting op: the learned table is keyed by a population-level signature of the whole candidate set, not by a cell or a slot. There is no Moore-local learned state anywhere in the learner. +- GENUINELY MISSING: + 1. A declared reading that maps a group row (or Nars16x8 lane) to `(pos7, neg7)` evidence counts — Nars16x8's reading is undeclared; Register128's bounded-stats reading is declared only as power sums. + 2. An ONLINE incremental fold: the decision at step t needs the state through t−1. The mask-risc terminals are batch folds over a plane; re-running per decision is O(T²). Per-row incremental accumulate into a persistent group sink (equivalently: GroupSum over a one-row extent + `merge_group_sink`) may be expressible — must be TESTED, not assumed. + 3. Decay ≠ 1 (rank-weighted fold) — missing, but not required by BASE. + 4.

Only a gate ABOVE the register (GadamerRevision, roots as EvidenceMask) stops echo/closed cycles (:230-246). VERIFIED-IN-CODE / TEST-PINNED. +- The HashMap learner has the same property: replaying the same game adds the same evidence again; nothing in `credit()` checks provenance. Within one game each credited step is a distinct event, but across seeds/blocks a replayed game (same seed) would double-count. VERIFIED-IN-CODE (no stamp field in Ev or Pending). +- Separation proposal (not implemented): three distinct objects, never the same bits — + 1. **Statistical evidence** (pos7, neg7, n) in group rows / Register rails, written ONLY by the masked fold over the event table; every event row carries a provenance stamp (seed, game, move index) so duplicate rows are detectable and an echo arm can be built by duplicating rows deliberately. + 2. **The chooser's expectation** (e, Beta draws) = consumer projection of (1), never stored. + 3. **CE64 EpistemicState5** = declared certification only (Open/Associated/... with the contract's meanings), written by an explicit certification step, never derived from c thresholds. The probe's `Ev::state` threshold mapping should be treated as a diagnostic label, not canon. + The experiment's statistical confidence (paired sign-flip p, Holm, CIs from shared/lab.rs) is computed over BLOCKS and never written into any CE64 field. + +## 5. Proposed three-arm experiment (do not implement) + +### Arms (same probe, same `run_op`, same opponents, same signature) +- **Arm A — existing HashMap learner** (`BASE`: Learned, Retained(1), Structural, decay 1.0, cost 0.02). Unchanged. +- **Arm B — canonical state.** Each credited step appends one event row to a column table (lanes: `key_id: U32` (fine and coarse as two rows or a remapped id), `recipe: U32`, `pos: I32 = max(a,0)`, `neg: I32 = max(−a,0)`, `stamp: U64` (seed, game, ply)). The chooser's row for (key, recipe) is read from a group sink produced by `GroupSumI32`/`GroupReduce` with `GroupKey::Pair{hi:key_id, lo:recipe, stride:9}` (or bounded power sums into Register0/Register1 group rows), maintained incrementally (one-row extent + `merge_group_sink`). e computed from (pos/7, neg/7) with the SAME k=1 formula. The CE64 record and EpistemicState5 are written exactly as today, write-only. + - **Sub-arm B′ (the representation probe):** drive the decision from CE64 F/C via `CausalEdge64::revision` per (key, recipe) cell. Prediction from the replica: diverges (w capped ≈ 22, f biased across 0.5); compare against A and against A-with-decay to locate it. +- **Arm C — negative controls (three, each needed):** C1 no learning (`learn:false`, untrained → always HPM via tie); C2 shuffled credit (permute activations across steps within a block, keeping the marginal distribution); C3 echo (each credited event appended twice / replay each game twice) — tests whether the arm is sensitive to duplicate evidence; for B, also with a stamp-dedup mask, which must restore A's behaviour. + +### Matched scenarios +- 9×9 five vs Threat, 16 blocks, fresh seeds (not 11/22/33, 2001.., 4001..), 300 games, endpoint last 100 window; opponent switch Threat→Lookahead for adaptation (Aggressor was uninformative, board entry). Same per-step rng stream (step_seed) in all arms so decisions are comparable move-for-move. + +### Independent outcome oracle +- Game result only (win=1, draw=.5) as the primary endpoint; the one-reply regret oracle is NOT independent (same signal as training) and is reported as secondary. Optional external: frozen evaluation vs Lookahead on unseen openings (Stage 4 shape). + +### Metrics +- **Decision agreement A vs B:** fraction of reasoning steps choosing the same recipe on the identical trajectory (run B as a shadow chooser on A's trajectory — avoids divergence after the first disagreement); pre-register "B ≡ A" as 100% under decay 1.0 (it is the same arithmetic; any miss = a carrier bug). +- Held-out score (frozen, unseen seeds), post-switch adaptation (score over first 2 windows after switch). +- Folds per decision (reasoning folds, and separately the bookkeeping cost of the reduction in rows touched). +- Materialized bytes: HashMap rows×(9×16 B) vs event table + group sink bytes; heap allocations per decision (counting allocator in the probe). +- Replay determinism (byte-identical stats across two runs, as `replay_is_deterministic` :2354-2365). +- Calibration: ECE of e vs observed productive, all and non-neutral (lab::reliability). +- Provenance: every B decision traceable to the set of event stamps that formed its row; echo arm must show detectable duplicate stamps. +- Statistics: paired sign-flip p + Holm over blocks (lab.rs), never stored in CE64. + +### If B cannot be expressed — the exact capability to test +1. "Incremental keyed fold": append one event row and update one (key, recipe) slot of a persistent group sink without rescanning the plane, bit-identical to a batch `GroupSumI32` over all rows so far. Falsifier: after every step, batch fold == incremental sink. +2. A declared reading of a group row (Register rails or Nars16x8) as `(pos7, neg7)` counts. Falsifier: round-trip + saturation refusal at the u8/u16/u32 bound instead of silent wrap. +3. (Only if decay is wanted) a rank-weighted fold; out of scope for BASE. + +### Premise problems flagged +- 16-bit lanes cannot hold f64 sums; but the sums are integers ×1/7 (activation ∈ ℤ, :936), so exactness needs integer counters, not floats — f64 is an implementation choice, not a requirement (decay ≠ 1 aside). +- Tenants 18-20 are indexed by Moore slot; the learner is indexed by (board-level signature, recipe). "Moore-local recipe learning" is Moore-local only in HYDRATION (candidate cells), not in learned state. Mapping recipes onto 8 slot lanes would be a category error (9 recipes, no geometric meaning). +- MooreNars16 carries no F/C at all; "lift_ce64" drops bits 0..39. The ISA-equivalence result does not cover revision state. +- CE64 u8 F/C revision is not the persistent learner: it saturates at w ≈ 22 and biases f (replica). Using it for Arm B tests a different learner. +- EpistemicState5 thresholds in `Ev::state` overload certification with statistical confidence; contract says observation/evidence is not a coordinate. +- The certified-minimax "arm" is a realization flag (H4), not a chooser arm; it does not interact with the representation question except through the cost term. +- Gadamer roots are a bitmask EvidenceMask (u64 or [u64;N]); per-game roots at thousands of games need [u64;N] with N ≥ games/64, and the policy is declared textual-hermeneutic, so applying it to game outcomes is itself a hypothesis. + +## Grades summary +- VERIFIED-IN-CODE: learner state type/update/decision (probe :811-927, :869-899); CE64 write-only (:950-958, :1344); no tenant use; MooreNars16 has no F/C (moore_tenant.rs:107-121, :211); revision formula + u8 rounding (isa.rs, edge.rs:371-379, :723-734); duplicate inflation (gadamer_isa_revision.rs:265-271, chain_confidence.rs:89-125); mask-risc terminals (ir.rs). +- MEASURED-BY-REPLICA (python, not repo-pinned): u8 F/C saturation at C=244 / w≈22 and f sign-flip. +- CLAIMED (board entries): score numbers, H/T verdicts, ECE. +- ABSENT: any tenant 18-20 read/write in the learner; a declared counts reading for Nars16x8/Register rails; an incremental keyed fold op; a rank-weighted (decay) fold; a provenance stamp in the learner. diff --git a/.claude/research/2026-10-recovery/BILANZ-session-2026-10-08-bis-10.md b/.claude/research/2026-10-recovery/BILANZ-session-2026-10-08-bis-10.md new file mode 100644 index 000000000..3922d04ed --- /dev/null +++ b/.claude/research/2026-10-recovery/BILANZ-session-2026-10-08-bis-10.md @@ -0,0 +1,435 @@ +# Brutally honest accounting of session 01EFw2…R (2026-10-08 to 2026-10-10) + +Scope: every commit carrying this session's trailer in lance-graph, ndarray and stockfish-rs.

The reference test has a `flip` arm (sign disable). +- **Why it is clean:** + - The direction is an enum (`MortonDir`), not a signed offset. + - It uses an existing ndarray facade word (M7), has an independent oracle (M6 A4), and is unsigned. + - It is exactly the seed of the `.arxiv/2605.01487` mechanism (X14), which no one had connected back to it. +- **Caveat (binding):** + - It runs on a 1-word field. At field scale, `mask_shift_morton` writes a full `dst` plane (simd_masking_ops.rs:5384-5386) and cannot be tiled: a sub-span drops the boundary carry (:5352-5362). The probe therefore does NOT prove deforestation at 64K. + - F-a: `dst` is OR-accumulated; the probe only works because it passes `[0u64]` fresh each time. + +### S2 — `fold_join_probe` (D-RPF-9) +- **Where:** `1c43faa5`, `91d9784b` (Codex P2 ×2: physical scratch, mask patterns before merging), `crates/lance-graph-quack/examples/fold_join_probe.rs` (on main). +- **What it has:** a measurement of which existing lowering already avoids the intermediate population. +- **Why it is clean:** + - Probe only. No new kernel, no new IR node. + - It asks the right question (M13) against the existing quack surface (M7). +- **Caveat:** + - Timings without a target-cpu label are anecdotes. + - It does NOT test the materialization-invariance assertion from 2608.00546 (`fold(mask) == fold(materialize(mask))`) as an explicit gate. That has to be added (MHP-16 A). + +### S3 — PROBE-PREFILTER-MASK: MetaFilter as a row mask +- **Where:** `27187638`, `f7426168` ("a lower bound above a narrow field's maximum admits nothing"), `examples/meta_prefilter_mask_probe.rs` (on main). +- **Why it is clean:** + - Pure admissibility (M5), on existing ndarray masking ops. + - The second commit is an honest can-stay-silent case. +- **Caveat:** check against M2 that "MetaFilter" is read as a row-plane predicate and not as a field-intent mask. **OPEN**: I have not re-read it. + +### S4 — Gadamer gate: echo and cycles cannot mint confidence +- **Where:** `552e6c3e`, `crates/lance-graph-planner/tests/gadamer_isa_revision.rs` (tests only, on main). +- **What it has:** + - `echo_cannot_mint_confidence` + - `a_closed_cycle_cannot_mint_confidence` + - can-fire arm `new_independent_roots_are_revised` +- **Why it is clean:** + - Two-sided (can-fire + stay-silent). + - Exactly the content of `.arxiv/0712.1182` (cumulative fusion only on independent evidence) and SCOUT T10 (duplicated provenance is not independence). +- **Caveat:** + - It uses `CausalEdge64` revision. Revision rounds with `(x*255).round()`, half-away-from-zero, without a declared mode (1905.12322). The test is clean; the arithmetic underneath is not declared. + - Under R3 (total `forward`) it has to be re-run. + +### S5 — Pins of real CE64 defects (defect records, not fixes) +- **Where:** + - `0340e64b` `planner/tests/chain_confidence.rs`: replay_step saturates confidence 200→224→237 (double counting per hop). + - `6f627af5` `causal-edge/tests/ce64_op_contract.rs`: self-revision raises c; c=255 + c=255 → NaN → 0 ("certain + certain = no evidence"). +- **Why they are clean:** + - They pin the defects as non-normative instead of hiding them. + - Both are confirmed by `.arxiv/0712.1182`: the cumulative rule is non-idempotent and needs a stamp. + - 2209.05433 confirms that c=255 is 0/0 even in exact integer form, so it is a policy cell, not an FP bug. +- **Caveat:** + - `chain_confidence.rs` calls `.forward(..).unwrap()` (:132). Under R3 the `.unwrap()` goes away. + - The c=255 policy is UNDECIDED; the test pins the defect, not a decision. + +### S6 — The 126-vector legacy capture +- **Where:** `crates/causal-edge/tests/ce64_legacy_capture.txt` (from `1bcb15b6`, on main). +- **Why it survives:** raw-u64 golden vectors of pre-strict behaviour. They are evidence, independent of the decision the same commit made wrongly (V3). +- **What must change:** `ce64_isa_golden.rs:120/:137` asserts "71 reproduce, 55 refuse". Under R3 it has to read "126 reproduce through `forward`", and that needs a new loader test. + +### S7 — `isa.rs` field descriptors (`Field::span`) +- **Where:** `causal-edge/src/isa.rs` (from `1bcb15b6`/`bad7b157`, on main). +- **Why it survives:** + - It describes the frozen layout; it does not reinterpret it. + - Other code depends on it (`lance-graph-mask-risc/tests/resident_ce64_predicate.rs:12,19`, commit `14c45ee4`, another session). +- **Caveat:** `Opcode::decode` may only survive as a free strict decoder, never inside `forward` or `replay`. + +### S8 — D-LAB-P1: certified minimax on Gomoku +- **Where:** `a290220c`, `examples/moore_nars_gomoku_probe.rs` (on main). +- **Why it is clean:** a deterministic certificate (exact game value), with no statistics and no float. +- **Caveat:** it lives in the same file as the Thompson/global-memory arms (S-violation V7). The certificate stands; the arms around it do not. + +### S9 — ndarray `checked_affine` on PowerSums / CrossPowerSums (on master) +- **Where:** `d86b2f8`, `bfafa2f`, `1c8006b`, ndarray `src/simd_masking_ops.rs:2328, 2471`. +- **What it has:** + - The power sums of an affine image computed from the sums alone. + - Returns `Option`, refuses overflow (test reaches the i64 narrowing). + - Composition holds when both forms succeed; one case is pinned where only the stepwise form fails. +- **Why it is clean:** exact integer arithmetic, with overflow refused instead of rounded (M1). This is the BF16 lesson done right ("wide accumulate, narrow once"). +- **Caveat (important):** + - The parameters are `i64` (`a, b` and `m, t`). + - The arithmetic is exact. Usage must not become a signed mask or a signed offset coordinate (that would be V9). + - Allowed: transforming power sums. Forbidden: deriving addresses or windows from it. + +### S10 — ndarray infrastructure and documentation (on master) +- `11c3267`: nightly/native rust-cache keyed by the runner's target features. Cache correctness, no semantics. Clean. +- `d7d86c1`, `fcbb506`: flag deferred pillars and document Stroke 1 recall. An honest record of a limitation. Clean. +- `9a63e7a`: splat3d clippy 1.99. Clean. + +### S11 — PackedDatabase stroke-split pin (draft #354, NOT on master) +- **Where:** `035d73b`, ndarray branch `ccr-b2e415d9-4jfvyk`. +- **Why it is clean:** it pins that the two stroke packers agree at 2048 bytes (existing behaviour). Its blackboard correction `5cc83b4` honestly records the withdrawal of the signed window helpers. +- **Status:** a draft, not merged; that is correct. + +### S12 — P5: NARS ↔ Beta correspondence (tests only) +- **Where:** `6d004eac`, `causal-edge/tests/d_rpf_p5_beta.rs` (on main). +- **Why it survives:** f64 is used here only as an independent test oracle (A4) for the Beta posterior, not in the production path. +- **Caveat:** the module doc itself says "the f32 `expectation()` stays within its rounding". That admits production rounding, which M1 has to resolve: either `expectation()` is declared as an integer ratio, or it never enters a decision. + +### S13 — stockfish-rs D-CHESS-NARS-0a recipe census +- **Where:** `232c4b6` and later (`cb1779d` drift guard, `9db48e6` metadata in the fingerprint, `20e686e` "drop an unmeasured census-agreement count"). +- **Why it survives:** a census with a drift guard against lance-graph main. Unmeasured numbers were removed instead of kept. +- **Caveat:** + - The term "palette" for the 256-slot ogar-loco opcode codebook (`bbcf8ed`) contradicts M3 (palette = LUT). + - All commits carry a model identifier in their trailer (V13). + +### S14 — The `.arxiv` findings themselves (newly read, not code) +- `2605.01487`: autocorrelation is a fold; symmetry caps the claim at association. +- `2608.00546`: materialization/lowering invariance. +- `2609.22106`: a fixed ISA with plastic layout. +- `2608.11034`: fold before mask, explicit Inconclusive. +- `2607.21273`: Moore = predictor, never purpose or causal rank. +- Together they are the yardstick against which X14/X15/X20 are measured (section 4). + +--- + +## 2. TEARDOWN — what is NOT clean + +Each item covers: +- **What / where**: commit and file. +- **Why it is not clean**: which rule it breaks. +- **Verdict**: RETEST / REMOVE / STORNO. +- **How to retest**: setup, oracle and pass/fail. +- **Corrections and details to adhere to.** + +### T1 — Signed Register128 readings + per-concept law table +- **What / where:** + - `14831543` (signed carvings 32×i4, 16×i8 with a per-family law). + - `96304b88` (law from concept and slab). + - Board `4c8dc638`, `b98d4573`. + - Code: `lance-graph-contract/src/register128.rs` (RegisterCarving :189, RegisterLaw :224-236, SignedRegisterRefusal :241, SignedRegisterLanes :277, read/write_i4x32/i8x16 :358-420). + - `hotplug.rs` (register_laws :136, with_register_laws :162, register_law_for :173, SlabReading::RegisterI4x32/I8x16 :253/:257, from_tag 2..=7 :271, bind_signed_register :480, errors :564-575). + - `atoms.rs` I4x32::from_bytes :85 / as_bytes :91. **On main.** +- **Why it is not clean:** + - M1: these are signed readings of a register that hold relative offsets. + - M11: `register_laws` is exactly the per-concept table that `hotplug.rs:43` forbids ("No per-concept permission table"). + - The module doc lies after the change: `register128.rs:39` still says "`Register128::words` is the only interpretation this crate provides". + - "RelativeOffset/AxisPosition" models geometric coordinates as signed numbers. That is exactly what M1 forbids, and Moore directions are already an enum (S1). +- **Verdict: REMOVE (R1).** + - Clean revert: `96304b88` first, then `14831543`. + - Only 3 code files change. No consumer exists in any of the 6 repos (AUDIT S3 #2, S4 #1). +- **Corrections and details:** + - (a) `from_tag` must refuse 2..=7 again, fail-closed: add a new test asserting `None` for 2..=7. + - (b) The test at `register128.rs:658` goes away with the revert. The call sites of `I4x32::from_bytes` (:367, :410) also go away. + - (c) `I4x32` itself (atoms.rs) is pre-existing and stays. + - (d) `CausalWitness` (tenant 14, signed ±8 window offset nibbles, canonical_node.rs:1027-1044) and `Qualia` (signed i4) are pre-existing. They are channels/pointers, not masks, so out of scope for R1. **They must be named explicitly as such**, so that R1 is not read as "all signed i4 removed". + - (e) Evidence that no persisted activation with tags 2..=7 exists has not been provided. State that check before the revert. +- **Idea worth retesting:** "relative position in a register". New setup: the `MortonDir` enum + `mask_shift_morton` (S1). No signed coordinates. Oracle: brute force on Morton-decoded (q,r). + +### T2 — Value tenants 18-20 (Nars16x8, MoorePalettePairs, MooreNars16) +- **What / where:** + - `28ec7c07` (tenants), `75c83c45` (docs, tenants 16-20, Moore LE contract). + - Probes `3581b1f5`, `0acab725`, `bb098c0d`. + - Board `b5d5b20a`. + - Code: `canonical_node.rs` Nars16x8=18 :1107, MoorePalettePairs=19 :1114, MooreNars16=20 :1125, "RATIFIED" :1101/:1122-1124, mint rows :1315-1331, BoardAggregates re-based to 21 :1311, tenant_bytes 252→300 (Full row ends at 332), const assert :1488. + - `moore_tenant.rs`: MooreNars16 :121, from_ce64 :199, ce64_upper :213, DirectionReading :224, MooreTenantView/Mut :283/:322, lift_ce64 :370, in-file tests :401-470 incl. `len()==21` :437. + - `band_reading.rs:150`. **On main.** +- **Why it is not clean:** + - **M11:** no operator ruling, no batched mint, no envelope-auditor verdict. "RATIFIED" was self-declared (entry `2026-10-08-hhtl-nars-moore-value-tenants.md:3`, `tenants.md:61,63`). The council entry of the same day explicitly says "the council ratifies nothing" (AUDIT S1 #8-9). + - **M10:** `MooreNars16::from_ce64` reads CE64 bits 46..49 (the signed inference mantissa, layout.rs:17) as "Energy4", without a version gate. + - **Fabrication:** `ce64_upper` writes bits 40-42, 46-52, 53, 59-63 and leaves 43-45 at 0, so it fabricates direction 000 (AUDIT S3 #4). + - **`.arxiv/2607.21273`:** "Energy4" as an action-relevant quantity on a Moore tenant is exactly the dark-room pattern (prediction becomes purpose). +- **Verdict: REMOVE as a hand-edit (R2), not `git revert`.** + - `28ec7c07` also created `MooreSlot`/`MOORE_LANES`/`ALL`/`index`/`offset`. + - The perturbation-sim examples (`MoorePertubationsfeld.rs:33`, `moore_observable_first.rs:84`, other sessions) import them, and CI runs them (`rust-test.yml:484-495`). +- **Corrections and details:** + - (a) **Operator decision A:** tombstone (18-20 RETIRED, slots reserved, BoardAggregates stays at 21) or delete (BoardAggregates back to 18). `canonical_node.rs:957-961`: "never move once instances persist, retired tenants are never reused". Delete is only lawful with proof that nothing persisted under the 21-layout (no Lance dataset, no bake with FieldMask bits 18-20 or the 300-byte schema). **Default without proof: tombstone.** + - (b) **Operator decision B:** `MoorePalettePairs=19` has clean LUT content (`tests/moore_palette_pairs_lut.rs`) but was not ratified. It must not fall away with the bundle without a ruling. + - (c) A G4 gate is mandatory: a diff check that `MooreSlot`, `MOORE_LANES`, `ALL`, `index`, `offset` are byte-identical before and after. + - (d) Remove the imports `moore_tenant.rs:30-31` as well, or `clippy -D warnings` fails. Rewrite the module doc :1-28 and the in-file test module :401-470. + - (e) `moore_nars16_probe.rs` still compiles after R2. Keep it (non-goal N1), but its Energy4 assertions become dead code. + - (f) `MooreSlot::offset() -> (i8,i8)` survives as a signed coordinate helper (N6). That is a remaining M1 tension; flag it explicitly to the operator rather than leave it hidden. +- **Idea worth retesting:** "Moore-local predictive state". + - New setup per 2607.21273: residual `popcount(pred XOR obs)` on Moore masks updates belief/LUT only. + - Pass: action order and causal grade byte-identical across a prediction-error sweep (MHP-17, P1/P2 from the paper). + - Positive control: a coupling built on purpose must fail (P12). + +### T3 — Strict opcode decoding in `forward` / `replay` +- **What / where:** + - `1bcb15b6`, `bad7b157`, `9fcfb8cb`. + - Duplicates `32a7ddf0` / `e60f2fff` / `d076a6a0` ("J follows the strict CE64 ISA"). + - Board `888fdc47`. + - Code: `edge.rs:668-689` (`forward -> Result`, `Opcode::decode(..)?` :676 / `decode_v1(..)?` :679). + - `network.rs:66`, `nars_engine.rs:601`, `chain_replay.rs:145/162/189/203/246/267` (+ doc :134-142). + - `stage26_v3_parity.rs:95-103`. **On main.** +- **Why it is not clean:** + - **M9:** 11 of 16 codes, including 0, now return Err. On the 126 legacy vectors, 55 now refuse, so replay refuses history. + - **M10:** the same name `forward` changed from `-> Self` to `-> Result`, which is anti-pattern AP1. + - **No authorization:** no operator request for it exists anywhere (AUDIT S1 #4). The nearest operator line was "CE64 op-set hardening … PROBE": that asks for probes, not a strict `forward`. + - The `chain_replay.rs` doc was rewritten to say replay "only refuses a step it has no instruction for". That contradicts its own neighbour `chain_admission.rs:113-121`. +- **Verdict: REVERT the semantics as a partial hand-edit (R3). Operator decision C first.** +- **Corrections and details:** + - (a) Total `forward` restores exactly the pre-`1bcb15b6` semantics: + - v2: `InferenceType::from_mantissa(inference_mantissa())` (0 → Deduction; ±6 → `Synthesis | _` arm with f/c averaged; resolved type stamped back via `to_mantissa()`). + - v1: the 3-bit `inference_type()`, 5/6/7 → the same `_` arm. + - One cfg split, in one place (AUDIT S2 #1-2, S3 #9). + - (b) Do not introduce `forward_checked`: admission has no opcode step (chain_admission.rs contains no decode/IsaFault), so it would be new wiring (AP6). `Opcode::decode` stays as a free function. + - (c) Keep `isa.rs` and its `lib.rs` `pub use` (S7). + - (d) `git revert` is not clean. Order: `bad7b157`, `9fcfb8cb`, `1bcb15b6`, or a hand-edit (about 15 files). + - (e) **Code from AFTER the strict change that depends on it** (other sessions or later work) must be adjusted in the same change: + - `causal-edge/tests/d_rpf_conf_0.rs:384-385` (`8d716f99`, asserts `Err(Unsupported{mantissa:0})`). + - `planner/tests/d_rpf_table_1.rs:21,205-212` (`e9ac316e`). + - `planner/examples/d_rpf_table_1_bench.rs:181,184`. + - `planner/src/chain_counterfactual.rs:52,225-247`. + - `chain_confidence.rs:60,80,99,123,132`, `dcr_w0_replay_budget.rs:127`, `moore_nars16_probe.rs:365`, `syllogism.rs`, the in-file test `edge.rs:1499`, the three `ce64_isa_*` tests. + - (f) The doc `docs/architecture/ce64-semantic-upper-half.md` (+16 lines from 1bcb15b6) must be corrected too. + - (g) G2: a new loader test with all 126 vectors replaying through `forward` without refusal; it has to run under v1 and v2 layouts. + - (h) Also delete the duplicates `32a7ddf0`/`e60f2fff`/`d076a6a0` in substance; `d076a6a0` is not on main. +- **Idea worth retesting:** "making unknown opcodes visible". + - New setup: an admission-side check, once per chain, in the `chain_admission::validate_chain` pattern. + - Replay stays total. Admitted set ⊂ replayable set, stated explicitly (AUDIT S5 #7). + +### T4 — Mexican-hat probes D-MHB-1 / D-MHB-2 and R-MHB-1 +- **What / where:** + - `3f84990c`, `60dde2e8`, `93fcf740`. + - Board `3d55b561`, `5028237c` (R-MHB-1 blocker), `3f84990c`'s entry `2026-10-08-mexhat-bucket-cascade-probe.md`, `mexhat-df-choice`. + - Code: `crates/lance-graph-mask-risc/examples/mexhat_bucket_probe.rs` (1128+204 lines, on main). + - **R-MHB-1 never landed in production code** (VERIFIED: no MHB/pos_plane/neg_plane in mask-risc or quack `src`). Only the board record of the blocker exists. +- **Why it is not clean:** + - **M1:** arm A is an `f64` DoG with `exp()` and π (:106-113); quantisation measured against it. + - **M5 (A2):** arm F and the R-MHB-1 proposal carry weight bits as mask planes (signed Pos/Neg planes). + - **M7:** arms D/F/Q are separate evaluators. R-MHB-1 would have needed a new window terminal (a new kernel). + - **Geometric 2-D window** instead of the Morton shift (S1). + - The probe is cited as a reference in the X12 class ("geometric window"), so it is not an oracle for anything new (falsifier addendum). +- **Verdict: STORNO of the ADOPT rows and of R-MHB-1. The probe file stays as a historical example, marked non-normative (N1). RETEST the core idea with a different setup.** +- **Corrections and details:** + - (a) Record the storno append-only in STATUS_BOARD :39-40 (D-MHB-1/2), plus the entries `mexhat-bucket-cascade-probe` and `mexhat-df-choice`. + - (b) The float arm must never again serve as a reference for a decision. An oracle must be integer brute force. +- **Retest (new setup), the main candidate:** + - The Mexican hat as unsigned ring counts per `.arxiv/2605.01487`: + - `C(Δ) = popcount(M ∧ shift(M,Δ))` over Moore directions on the 64K Morton field (256×256 = 4^5 words); + - rings are unsigned; + - centre vs surround decided in jc by u64 cross-multiplication `P_1·N_2 ≥ P_2·N_1` (≤ 2^40, so u64 is enough and u32 overflows exactly at 65536²). + - **Preconditions (binding):** + - (i) a fused terminal `popcount(M ∧ shift(M,dir))` as a NEW LOWERING over existing facade words (per word: interior case-shift + one carry word, AND, popcount, no `dst` plane). Without it, X14 is NOT deforested (the fit review was a BLOCK on the claim, AUDIT). + - (ii) Operator ruling F-c: does a ring count cells (`popcount(M ∧ ball_k \ ball_{k−1})`, Chebyshev, needs diagonals) or pairs (`Σ_Δ C(Δ)`)? O_k ≤ P_k, strictly smaller on dense input. + - (iii) F-a: zero the scratch the caller owns, never allocate. + - (iv) F-b: pin the absolute direction sign (the reference maps "+x" to `NegQ`). + - **Probes:** + - MHP-11 symmetry `C(Δ)==C(−Δ)`; disables: uncleared buffer, wrapping diagonal. + - MHP-12 rings, both arms. + - MHP-15 allocation `bytes(10) == bytes(1000) == bytes(60000) == 0`, using the `Counting` allocator from `mask-risc/tests/no_alloc.rs`. + - MHP-16 materialization and row-major/Morton invariance. + +### T5 — Algebraic recipe table D-ART-1/2 (percentile profiles × Wankel phasors) +- **What / where:** + - `e659eebb` (1579 lines), `34ee0511`, `a0924323` (value-relative tolerance), `a56a72f3` (tolerance floor Σ|p|²+m), `c7cdb5c3`. + - Board `3d55b561`, `3cac3ca0`, `623afdfc`. + - Code: `examples/algebraic_recipe_probe.rs` (on main). +- **Why it is not clean:** + - **M1:** the probe works with tolerances ("value-relative tolerance", "tolerance floor"). Tolerance is admitted rounding. + - It runs on the f32 `PhaseLut`. + - The **recommendation** for a signed affine transform (D-ART-1) shifts signed arithmetic into the recipe surface. The code of `checked_affine` itself is exact (S9); the recommendation is the problem (V9). +- **Verdict: RETEST, recommendation STORNO.** +- **Retest:** + - Exact power sums through `checked_affine` with tolerance **0**, using a u128 oracle. + - Failure is `None` (refusal), never "inside the tolerance". + - Percentiles as integer ranks `(i+1)*n/bands` (the pattern already shown in nested_bands.rs:196-198). + - Phasors only in the integer turn domain (see T6). + +### T6 — `hpc::phase::PhaseLut` (f32) re-exported via `ndarray::simd` + phasor probe D-PHT-1 +- **What / where:** + - ndarray `b5454d1` (on master): `src/hpc/phase.rs`, `table: Box<[[f32;2]]>` :86, `lerp` :216 with f32 interpolation, `lerp_batch` :243, "stated error bounds" :258. Re-exported in `src/simd.rs:670`. + - lance-graph `b44e85ff` (on main) / `1e90afc3` (duplicate, not on main), `examples/phasor_trig_probe.rs` (756 lines), `3f4195a6`. +- **Why it is not clean:** + - **M1:** a LUT with stated f32 error bounds is rounding by construction. + - Being re-exported via the `ndarray::simd` facade, every consumer can use it as substrate. The phase itself (u32 turns) is exact; the values are not. +- **Verdict: CONCERN, not an immediate remove (it is on ndarray master, and other consumers may already use it).** +- **Retest / correction:** + - Pin the phase domain as exact (u32 turns, `PhaseStep` drift-free accumulator: that part is clean). + - Mark the cos/sin values explicitly as non-substrate (not admissible in any decision, mask or count). + - If a decision is needed: compare phases in the integer turn domain (sector = top bits), never via cos/sin. + - Operator decision: whether the f32 surface should stay in the `ndarray::simd` facade at all. + +### T7 — The lab: D-SELF-CALIBRATING-LAB-0 (`shared/lab.rs`) +- **What / where:** + - `df683e50`, `730e584f` (Thompson + global memory), `8c6ec3ca` (crossword arm), `608350e1` (min-effect gate). + - Board `460a01b3`, `25e09b25`, `b448d888`. + - Code: `crates/cognitive-shader-driver/examples/shared/lab.rs` (377 lines, on main): `paired` (t-test with a T975 table :70), `sign_flip_p`, `holm`, `reliability` (ECE), `brier`, all in f64. +- **Why it is not clean:** + - **M8:** this is a second statistics home beside jc (`stats.rs` has `t_test_paired/welch/anova`, plus `reliability.rs`).

The dots to connect, and why + +**D1 — The resident cycle is three merged pieces plus one variant.** +Composition (C2) + split-tunnel write-back (#1466: one SET per changed lane) + +plug readings (#1465/#1474) give everything the cycle needs except a +`SlabReading` variant that can declare a Moore lane (O11). The tenant hygiene +item (O2a) and the opcode-in-edge test (O10) ride along. Why it matters: it is +the only way "NARS16 × 8 is resident state" stops being a test-held payload, which +is exactly what #1406's equivalence relied on. + +**D2 — One provenance identity closes four open points at once.** These look +unrelated and are the same question, "which independent source does this +evidence come from": + +| where | symptom | +|---|---| +| CE64 witness (C3) | the handle should resolve to a transition record | +| split-tunnel log | every record already carries `(version, owner, op, row, lane)` | +| `replay_step` (O25) | no check, so deduction re-counts the same evidence | +| Gadamer (O24) | `independent_roots` vs `inherited_roots` need a stable root id, and claims need to point at the steps that support them | +| F.2 arm C3 (O8) | echo inflation is the same defect measured statistically | + +If the root id of a piece of evidence is the coordinate of its log record, then +the witness resolves to it, `replay_step` can refuse a root already in the +running base, Gadamer roots become those ids, and the claim ↔ step map is "the +records this claim's chain consumed". No new registry: the log already exists. +This is the keystone; it is heavy only because it touches four places, not +because any one is hard. + +**D3 — Ablation already has its readouts; it lacks the joints.** +Pearl gives three reactions, the crossword probe four (incl. SilentlyNecessary), +`first_divergence` the location. Joining them: cut → two traces → +`first_divergence` → per-step XOR = cone (O27) → reaction → verdict (O22). For +many cuts, D-PHOTO-0 says carry each scenario's reachability as a bit-sliced +plane, scoped by a population-cache descriptor (O28). Only Boolean reachability +is cheap that way; each scenario's truth replay is a separate run. + +**D4 — Gadamer revision already compiles to folds.** `quack/tests/spofc_cycle.rs` +shows its kind decision is a scalar table over seven `Any` folds and its result +three `Keep` outputs. D-SQLP makes R2IL procedures the API over mask-risc. So +"revise" is a natural procedure candidate. Not authorized beyond D-SQLP W3; record +as a candidate, do nothing now. + +**D5 — Every gate here has the same abstain contract.** The certified +decide-or-abstain of D-MOORE-OBSERVABLE-FIRST-0, Gadamer's Suspend / +GroundingRequest, quack's refusals, and `CounterfactualVerdict::NotRun` are one +pattern: decide only with a certificate, otherwise say so. The trigger stages +(coincidence, veto, contrast) belong in front of it as cheap filters that +choose which events earn a CE64 op. This is why O15 (detection quality) matters: +a filter that is fast but not measured for recall is a Stroke-1 risk (O20). + +**D6 — Purpose is never derived.** The dark-room doctrine (`.arxiv/2607.21273`: +prediction may update belief, never purpose), the Moore-as-predictor note +(X20 in the coresearch crosswalk) and the `causal_bridge` defect (O26) are one +contract: purpose claims need their own evidence class (O33) and must never be +produced by prediction or by causal certification. + +**D7 — A moving focus is an actor, not an owner.** #1491's one-subject rule plus +split-tunnel rule 2 (one writer per log) mean a focus crossing owner boundaries +issues one write per owner, each under that owner's authority. Experiment B +(O17) must count those writes; "one focus, many owners, one commit" is ruled out. + +## 6. What I aim for, in order + +**Low (hours, no operator needed):** +1. **O22-min + O25-pin + O26-pin** — three planner/learning tests. One maps + LoadBearing → Necessary and Inert → Dispensable on a one-claim chain and + reaches `is_acceptable()` end to end for the first time; TruthOnly stays + NotRun. Two pin existing defects (deduction mints support; intent becomes + cause) so their fixes later have a failing test to turn green. +2. **O8 (F.2)** — the learning seam; no new primitive. +3. **O1 + O2a** — board supersession and the reading-free tenant hygiene, + answering the two Codex P2s. + +**High (a PR with a probe, or one answer):** +4. **O11 + O12** — the Moore `SlabReading` variant through the plug, then the + resident-cycle test (D1). Can start test-local while the variant is reviewed. +5. **O27 + O28** — divergence cone and multi-cut scenarios as planes (D3). +6. **O5 → O6** — `lab.rs` into jc, then its defect fixes. +7. **O15** — Experiment A, once you say go. + +**Heavy (needs design or open science):** +8. **D2** — the provenance identity, fixing O24, O25, C3's handle and O8-C3 + together. +9. **O29** — horizon-identity revision: write the T8 falsifier first. +10. **O33 / O34** — teleology evidence classes; connecting `learning::scm`. +11. **O4** — replay compatibility, after your decision. + +## 7.

The only verified link between the two is the +`gadamer_isa_revision` test: numerical revision runs only on `IncreaseEligible`. +Note one wording risk: the doc on `HorizonFusion` calls it "thesis × antithesis × +synthesis". The behaviour is Gadamerian (tension accumulates by union, never +cleared), but the vocabulary invites the Hegelian misreading. + +## C. Teleology + +Nothing distinguishes intentional goals, functions, means–end inference, +retrospective rationalisation or unsupported purpose attribution. What is +representable today: + +- a purpose as a **claim bit** inside a horizon, with its roots, so it can be + withdrawn, exposed or preserved in tension by `GadamerRevision`; +- a cause, earned by the certification ladder. + +What is not: any evidence class that licenses a purpose (intent evidence, +selection history for a function), so a purpose claim can only be supported by +the same roots that support a cause. The live defect is +`causal_bridge.rs:190`, which turns "A intends B" into a causal certification. +`.arxiv/2607.21273` is the only doctrine: a predictor may update belief, never +purpose; its falsifiers are not implemented. + +The ablation scenario ("X in order to Y; remove X; Y survives via Z") maps +cleanly onto existing readouts: chain cut gives TruthOnly or Inert at the +terminal, the crossword readout separates Redundant from SilentlyNecessary, +and F7 already shows overdetermination keeping `Causes`. What is missing is the +step that turns that result into resistance against the purpose claim: nothing +connects an ablation result to `EncounterEvidence.resistance`. + +## D. Ablation as introspection + +Composable from existing parts, measured separately: + +1. **Reachability / closure:** run the factual and cut traces through + `replay_chain`; `first_divergence` locates the first changed step. +2. **Cone:** the steps whose `(predicate, edge)` differ after that index; a + per-step XOR of the two traces. Not implemented. +3. **Evidential support:** per-step (f, c) difference, already in the trace. +4. **Certification:** `pearl::reason` with `Edit::CutStep` gives LoadBearing / + TruthOnly / Inert; F3 pins that a load-bearing cut is not `Causes`. +5. **Terminal verdict:** `chain_counterfactual::EdgeRole::is_load_bearing`. +6. **Uniqueness / redundancy:** the crossword four-way readout; its + SilentlyNecessary case is exactly "the answer survives but now rests on + something else". + +Overdetermination needs joint cuts. The edit type supports one cut. A u64 mask +can carry 64 cut scenarios for Boolean reachability over a step mask, but that +is reachability only; each scenario's CE64 truth replay is a separate run and +must be counted as such. + +`.arxiv/2607.21573` (necessity by disruption), `2202.08816` (necessity and +sufficiency) and `2603.04209` (search must exceed edge deletion) are the +literature this lines up with; the last one says single-edge deletion alone is +not a complete counterfactual search, which is the current limit. + +## E. 64 logical lanes + +Do not map 64 lanes onto the AlphaTunnel. Its 10 lanes are the recipe rungs +(`rung_schedule::LEVELS = 10`, `MAX_RUNG = 9`); widening it would redefine rungs. +The five axes stay separate: rung (≤ 10), CE64 bit position, SIMD lane, cut +scenario ordinal (could be 64, one bit each), Alpha overlay owner. + +The 34 recipes do not cover the sequence.

Candidates, all operator decisions: +`Nars16x8` as f8:c8 (undeclared), `MoorePalettePairs` as two of the three +indices, the Moore slot as the predicate.

A field an op changes persists as one + sparse `(version, owner, op, row, lane, present, value)` SET record, never a + 64-bit image. So CE64 never needs to persist as an object; it is composed + from lanes on read. This supports D's idea. It does not remove the need for + a lane that holds bits 0..39. +- Rule 7 decides what an event may persist: derived reads write nothing; only a + learned outcome is stored. So NARS revision and plasticity changes persist; + contrast scores, trigger decisions and trajectories are recomputed, never stored. +- Splits the runtime target. A fold costs about 1.7 ns (0.6 ns per resident + record measured) and a durable write about 1.7 ms, with one Lance version per + batch. "7 ns per event" can only describe the resident apply; durability is + per batch. Experiment E needs both rows: event applied resident, and batch + committed. +- Rules 4–5 are Experiment D's replay test as shipped practice: install only + after a full replay, refuse an out-of-order log, replayed history identical. +- One writer per mailbox comes from ownership; a racing writer is only + detected afterwards (OPEN). A moving focus must not write on behalf of + several owners without that guarantee. + +**OGAR #350 OGIT tables** (`ogar_action_handler::ogit`): +- Same contract shape the event needs: u16 row ids, u32 lanes lent zero-copy as + mask-risc `LaneRef::U32`, refusal past 65,536 rows instead of widening, names + kept out of lanes, nothing dropped silently (rejected / duplicates / unresolved + reported). The last point is what `Cascade` Stroke 1 violates. +- `Allowed (src, verb, dst)` is a legality table for triples. An event's S/P/O + could be checked against it with one mask-risc fold before the CE64 op runs: + a semantic veto stage, distinct from the statistical trigger stages. +- Caution: OGIT ids are row ordinals of an ontology, not Palette256 indices; + using `Allowed` would need a declared mapping between the two, not an + assumption that they coincide. diff --git a/.claude/research/2026-10-recovery/PAPER-2604.18873-nars-reasoning-benchmark.md b/.claude/research/2026-10-recovery/PAPER-2604.18873-nars-reasoning-benchmark.md new file mode 100644 index 000000000..d1e100644 --- /dev/null +++ b/.claude/research/2026-10-recovery/PAPER-2604.18873-nars-reasoning-benchmark.md @@ -0,0 +1,42 @@ +# arXiv 2604.18873 — "From Natural Language to Executable Narsese" (Gabriel & Wang, Temple) + +**Grade:** READ-IN-FULL. **Status:** OPEN — candidate external probe, nothing adopted. + +## What it is +NL -> FOL -> (deterministic compiler) -> Narsese -> ONA -> {True, False, Uncertain}. +Benchmark NARS-Reasoning-v0.1: 1,000 ProverQA-derived instances, depth tiers +easy 1-2 / medium 3-5 / hard 6-9 steps (400/300/300; split 800/200). +Dataset `MinaGabriel/NARS-Reasoning-v0.1` on Hugging Face, CC-BY-SA-4.0. + +## Weak points (read before citing) +1.

Missing-seam experiment (smallest still-unproven step) + +### F.0 Premise correction (load-bearing) +The #1400 learner's state is keyed by **(board situation signature, recipe)**, not by Moore lane. Moore enters only as candidate generation (cells with a stone in their 8-neighbourhood). Tenants 18–20 are indexed by Moore slot (8 lanes), MooreNars16 carries no F/C. So "do tenants 18–20 carry the demonstrated learning?" is not well-posed as stated: the representations index a different axis. The well-posed first question is whether the learning loop runs **exactly** through canonical primitives at all; the Moore-lane question is a second, separate experiment. + +### F.1 Five-part primitive ownership statement +1. **Hypothesis:** the persistent structural learner's evidence and decisions are expressible exactly through canonical primitives: a stamped event table + `GroupAddr::Pair{hi:situation_key, lo:recipe, stride:9}` grouped `SumI32`/`Count` (quack → mask-risc `GroupKey::Pair` → ndarray), with the k=1 expectation computed consumer-side, and statistical confidence kept out of CE64. +2. **Existing implementation:** quack `lower_group_by`/`lower_group_avg` with `GroupAddr::Pair` + `GroupAgg::SumI32` (lib.rs:1542-1600, :2368), mask-risc `GroupReduce`, no_alloc Counting allocator, Gadamer gate for echo, lab sign-flip/Holm for the block statistics (until moved). +3. **Missing capability (to be shown, not assumed):** (a) an incremental keyed fold (update one slot = batch result); (b) a declared reading for evidence counters on a row (if they are to live in tenants, not in caller-owned sinks); (c) decay ≠ 1 (rank-weighted fold) — not needed, H5 falsified. +4. **Independent falsifier:** Arm B as a shadow chooser on Arm A's exact trajectory must agree on 100% of decisions with decay=1.0 (integer pos7/neg7 sums vs f64 /7 sums are order-equivalent; any disagreement is a carrier bug or a tie-break difference, pre-registered). Disable run: drop one event row → agreement must fall below 100%. +5. **Canonical owner:** none new if (1) holds. If the incremental fold is needed for cost, it belongs in mask-risc as a terminal lowering over existing ndarray words; a declared counts reading belongs to the plug (SlabDeclaration), never a hand-read tenant. + +### F.2 Arms (matched seeds, fresh block seed range, 16 blocks × 300 games, endpoint last 100; plus a Threat→Lookahead switch) +- **A** existing HashMap learner (BASE, decay 1.0). +- **B** event table + Pair-keyed grouped sums through quack/mask-risc; same expectation; shadow on A's trajectory, then independent run. + - **B′** decisions from CE64 u8 F/C through `revision` (canonical epistemic carrier). REPLICA predicts divergence (C stall at 244, f drift). This tests Q2 directly: epistemic carrier ≠ statistical evidence carrier. +- **C** controls: C1 no learning; C2 shuffled credit (preserves marginals); C3 echo (each event twice) with and without stamp-dedup mask (Gadamer roots). + +### F.3 Measures +Decision agreement A/B (exact); held-out frozen score; post-switch adaptation; folds per decision and rows touched; materialized bytes and heap allocations (Counting allocator; must not scale with games played beyond the event table itself); byte-identical replay; calibration (ECE all vs non-neutral, empirical only); provenance (every count traceable to stamped events); echo inflation (C3 with vs without dedup). + +### F.4 Statistics +Block-level paired sign-flip with Holm (as pre-registered in the lab, to keep verdict comparability); A-vs-B agreement is deterministic, no test needed. Statistical confidence (p, CI) is never written into CE64; EpistemicState5 only carries declared certification. + +### F.5 Second experiment (only after F.2 passes) +Moore-lane question: reformulate a learned quantity that is genuinely slot-local (e.g. per-direction threat evidence around a candidate cell) and test whether Nars16x8 lanes can carry it under a plug-declared reading, against the same arms.

The question +The operator wants all thinking wired to the `CausalEdge64` register: its +SPOFC fields (S, P, O, F, C at bits 0..39) and what the operator calls its +"ALU ISA" half (bits 40..63). Where the register is the wrong home, thinking +should migrate onto the Moore masking algebra and the EWA sandwich. + +The inventory (`inventory.md`, alongside this brief) shows this is not yet +possible. Five questions are open: + +- **O1. Candidate identity and ranking.** How does a population of scored + candidates (chess: one score per legal move) keep the identity of each + score and support ranking? + - The mask algebra has membership only: no ORDER BY, no position terminal + (no masked argmax), integer lanes only. + - `ThoughtCtx.candidates: Vec` carries neither identity nor order. + - The chess census measured that every move-narrowing recipe loses move + identity: TCP, CUR, ETD, TCF, IDR, and CDT's convergent branch. +- **O2. A home for the thinking scalars.** free_energy, sd (dispersion), + dissonance, temperature and rung have no CE64 bits. + - Candidates on record: `MetaWord` (a sibling u32 column holding + thinking 6 | awareness 4 | nars_f 8 | nars_c 8 | free_e 6), or a side + table beside the register. D-CE64-CYCLE-0 measured that the evidence + table and attention state are needed and live outside the register. + - Bits are contested: 50..52 conflict with `learn`; 61..63 are now + Certification3. +- **O3. Does CE64 get a named instruction set (ALU/ISA)?** The operations + exist as functions but form no ISA: `pack`, setters, `forward`, `learn`, + `syllogize`, `NarsTables::revise`/`deduce`, `pearl::reason`/`revise`/`hydrate`. + Three conflicts: + - `forward` and every constructor zero W (53..58) and bits 59..63; + - the mantissa (46..49) has four readings (instruction, provenance, + polarity, energy), and Counterfactual is encoded as both −1 and −6; + - the mask and plasticity bit orders disagree. +- **O4. Contradiction on CE64.** There is no `contradicts(a, b)` and no + demotion policy (pearl only raises certification). Recipes CR, CDI and CWS + need contradiction to be a fact at register level. +- **O5. EWA as a trust propagator.** Σ' = M Σ Mᵀ is certified numerically in + `jc`. Its use for trust is PROPOSED (`mul-ewa-trust-propagation-v1.md`), and + its own falsifier F-MEP-0b says the suspicion score inverts under + M = √trust·I. No recipe uses EWA. + +**Why now:** D-CHESS-NARS-0 (stockfish-rs plan) needs recipes that act on +chess positions and are learned across games. The only learnable consequence +today is meta-state, and no recipe can narrow the move list. + +## 1b. Premise audit result: the questions are re-asked (this governs) + +The premise audit returned **PREMISE-WRONG** for the overall framing. Its +findings: + +- **Three kinds of state.** "Thinking" in the code is three kinds of state + with different cardinality and lifetime: + - (E) per-edge belief: one `u64` CE64 per edge; + - (T) per-thought / per-cycle scalars: the `ThoughtCtx` sd, free_energy, + dissonance, temperature, confidence and rung; + - (P) populations: `candidates`, `beliefs`. +- **Four "mask/EWA" artifacts, not one:** + - the Moore 4×4 plasticity probe; + - the mask-risc bit-plane vocabulary ("names no ISA", "no ORDER BY", A1 + forbids selection vectors); + - the ndarray kernels; + - EWA covariance propagation. +- **The lane-fold anchor** forbids routing through cognitive layers or the + shader driver unless an explicit exception is made. + +So the council answers these questions instead of O1–O5 as first written: + +- **Q0. Carriers.** For each kind of state (E, T, P), which carrier matches + its signature? Is "wire all thinking to CE64" right for E only? Options + include "the property belongs elsewhere". +- **Q1a.** How is a candidate's identity carried? (An ordinal address on the + population, not register state?) +- **Q1b.** Which carrier owns ranking: + - a lane-fold-style permutation; + - a semiring (`blasgraph` over CSR, "valued → semirings", + PLAN-INVENTORY-2026-09-07.md:308); + - a new position terminal; + - or the kernel? +- **Q2.** Where do the per-thought scalars live? A cycle-context or side + table? Are any of them genuinely per-row (`free_e`, `nars_c` in `MetaWord`)? +- **Q3a.** What closed operation set over a CE64 forms its instruction set, + and which operations must preserve W (53..58) and bits 59..63? +- **Q3b.** Does any CE64 field encode an opcode? The mantissa's "instruction" + reading is one of four. +- **Q4.** Split into four parts: + - (a) a binary `contradicts(a, b)` predicate over S/P/O plus F; + - (b) where a contradiction is stored (a pair relation); + - (c) the scan over the belief population (mask `GroupReduce`?); + - (d) the demotion policy. +- **Q5.** Does multi-hop trust belong to NARS deduction chains or semirings, + with EWA purely attentional? Or is there a bounded monotone + trust → step-transform mapping that makes EWA usable for trust? + +H3 (confidence delta → C byte) is not this council's question. It moves to +the 5+3 with a prerequisite: name which edge is the subject of a recipe's +confidence effect. + +## 2. Anchors (frozen; never re-litigate) +- **CE64 v2 layout** (`causal-edge/src/layout.rs:89-219`; all 64 bits + const-asserted once). Bits 59..63 are `EpistemicState5`, "semantically + opaque without a declared reading" (`edge.rs:1022`; `epistemic_state5.rs:43`). +- **I-VSA-IDENTITIES:** never XOR or bundle content registers. +- **Masks and magnitude are separate.** "a mask bit is never a weight" + (mask-risc A2, `crates/lance-graph-mask-risc/src/lib.rs:76-80`; + `E-TOPOLOGY-MASKS-MAGNITUDE-COMPOSE-NEVER-COLLAPSE-1`). mask-risc has "no + ORDER BY" (`lib.rs:101-103`). +- **EWA:** "EWA ranks WHERE to look, never WHAT is true". It may not mint + evidence. Do not store EWA covariance in CE64 (lineage addendum STOP 5). +- **Lane-fold capstone** (`.grok/board/CLAUDE_LANE_FOLD_CAPSTONE.md:18`): + "Do not route this through cognitive layers, the shader driver, or ontology + bridges." +- **Global-Sudoku plan:** no new CE64 bit allocation from that plan; no + `Vec` recipes; no global Moore relaxation engine. +- **ogar-loco** `DOMAIN_FLOOR = 0x90` is a stored-byte ABI; the core + `0x00..0x8F` is universal forever. +- **Zero-copy law; lance family upstream; AdaWorldAPI forks; no float/LLM on + the hot path.** +- **Falsifiability rule (lance-graph CLAUDE.md).** Every guard needs both a + can-fire test and a can-stay-silent test. + +## 3.

That means the Moore-neighbourhood + fold and the `lance-graph-mask-risc` / `ndarray::simd` bit-plane algebra. The + EWA sandwich is the uncertainty propagator alongside them. +3. Is the open question research-shaped? Those go to `/coresearch`. +4. Is it concrete enough to specify and harden?

Nothing names + them as one instruction set, and the phrase "ALU ISA" appears nowhere in + code or board entries for CE64. +4. **None of the 256 palette slots reads or writes CE64.** ogar-loco has zero + hits. lance-graph-ogar mentions it in two doc comments only. +5. **No recipe propagates anything across hops, so none has an EWA + counterpart.** The EWA sandwich (Σ' = M Σ Mᵀ, certified in `jc`) has no + production caller. Its trust use is a proposal, and that proposal's own + falsifier says the suspicion score comes out inverted (F-MEP-0b). +6. **The mask algebra can express the membership half of most population + recipes, but not the ordering half.** It cannot express ranking: + - mask-risc lanes are integer only; + - mask-risc has "no ORDER BY"; + - no terminal returns a position (no masked argmax). + + The chess census's identity finding is the same gap seen from the other + side. +7. **Two vocabularies mint the same 34 bytes `0x90..=0xB1` with different + specs.** `ogar_loco::nars::NarsVocabulary` gives Datapath recipes arity 2;

It is not: `nars.rs:47-51,139-141` call it + POLICY.) `RecipeVocabulary` is the ONE `FnSpec` mint for recipe bytes (arity 1 — + the operand is the attention-focus address prefix — plus the prefix-scoped + codebook). `NarsVocabulary`'s `impl Vocabulary` is DELETED from OGAR. + `nars.rs` keeps only the id↔byte map and the bucket classifier + (`recipe_at`, `byte_of_id`, `tier_of`). Rationale: the arity-2 Datapath + claim is asserted from bucket, not from any kernel ("these numbers are this + module's policy", `:140`); the arity-1 claim is test-pinned against a + consumer. Landing order: OGAR PR first; lance-graph-ogar follows `main` + automatically and needs no edit unless it imports the deleted impl (it + does not). +H2. The engine owns every SHARED-CORE byte that either sits in + `CONTROL_BAND` or references a body: `is_engine_control(f) := + CONTROL_BAND.contains(f.0) || (f.0 < DOMAIN_FLOOR && body_refs(f) > 0)`. + PROC_DEF then reaches `run_branching` and is refused with + `UnhandledControlFlow` (its existing `other =>` arm). The rule is + layout-shaped, not a per-byte list (honours the module's own anti-drift + note). Domain bytes (≥ `DOMAIN_FLOOR`) stay the dialect's even if a domain + declares body refs. Doc `:25` becomes true; no doc change needed. +H5. (Premise audit: "masking op" is a KERNEL property; the label was + derived from the catalogue's execution-tier bucket.) Fix the LABEL, incl. + the file header `nars.rs:1-2, :13`. `nars.rs` stops calling Datapath recipes + "masking ops": `is_mask_op` is renamed `is_datapath` (old name kept one + release as `#[deprecated]` alias — but it has no consumers, so delete + outright is acceptable; spec chooses DELETE since no consumer exists), + and the module doc says Datapath = "uniform per-cycle tier", with the + measured note that 6 of the 9 kernels are scalar ThoughtCtx arithmetic, + not mask ops. Mask migration of those kernels is coresearch O-work, not + this change. +H6. (RE-ASKED after premise audit: PREMISE-SPLIT.) The mantissa carries two + concepts here: the inference rule that produced the edge (read as an + instruction by `forward`, `edge.rs:~686`) and the rung-3 provenance tag + (−6, `chain_counterfactual.rs:253`). The rung itself already has its own + carrier, `ReasoningBand::Counterfactual` (`layout.rs:~331`; band and −6 + pinned as independent, `tests/v2_layout_tests.rs:896-925`). + Committed resolution (this council): `CausalNetwork::counterfactual` + ADDS `.with_reasoning_band(ReasoningBand::Counterfactual)` to its result + (v1: documented no-op, `edge.rs:1301`). The mantissa write is UNCHANGED in + this change; the comment `// counterfactual = abduction` is replaced by + one stating the mantissa records the rule, the band records the rung. + Tests: v2 band == Counterfactual after `counterfactual`; silence twin: a + `causal_query` hit is not banded Counterfactual. + DEFERRED to coresearch (Q3b): whether the −6 provenance tag on the replay + path should also move to the band, and what `forward` must do when a + weight edge carries −6. +H7. Both doc sites show the v2 layout as primary (S 0..7, P 8..15, O 16..23, + F 24..31, C 32..39, mask 40..42, direction 43..45, mantissa 46..49 i4, + plasticity 50..52, W 53..58, Epi5 59..63) and keep the v1 table under a + "v1 (default-features = false)" heading. Doc-only. + +## 4.

PRE-REGISTERED GATES +G1 OGAR: `cargo test -p ogar-loco` green; new test + `proc_def_is_refused_by_the_engine_not_offered_to_the_dialect` (anti-vacuity: + asserts body_refs(PROC_DEF)==1 and 0x83 ∉ CONTROL_BAND) red under the old + predicate, green under the new; silence twin: a domain byte ≥ 0x90 still + reaches the dialect; and a domain vocabulary cannot raise body_refs on a + byte < DOMAIN_FLOOR (test). +G2 OGAR: clippy -D warnings, fmt clean; no remaining `impl Vocabulary for + NarsVocabulary`; grep `masking op` in nars.rs returns 0. +G3 lance-graph: `cargo test -p causal-edge` green under default AND + `--no-default-features`; new counterfactual test disable-verified. +G4 lance-graph: `cargo test -p lance-graph-ogar` green against OGAR branch. +G5 Board: one lance-graph `.claude/board/entries/` entry + entries_index.py + --write; inventory doc (stockfish-rs) H-rows updated with PR links. + +## 6. PER-SAVANT QUESTION SETS + +S1 prior art: (1) Is any of H1/H2/H5/H6/H7 already fixed or decided in a board + entry, ISSUES row, or open PR? (2) Is there an existing ruling that NARS + recipe arity is 2 for Datapath? (3) Was "counterfactual = abduction" ever an + operator ruling? (4) Does an existing ID cover the PROC_DEF gap? +S2 iron rules: (1) Does H6 violate I-LEGACY-API-FEATURE-GATED under v1? + (2) Does H2's predicate let a domain vocabulary forge engine control? (3) + Does any change make the mantissa an opcode (F3)? (4) Does H1's deletion + break append-only or a published API rule? (5) AP1-AP9 hits? +S3 code truth: verify every file:line in §2 as CODED/CLAIMED/ABSENT; in + particular (1) `run_body` passes 0x83 to the dialect; (2) no consumer of + `NarsVocabulary`/`is_mask_op`/`tier_of` exists in OGAR, lance-graph, + stockfish-rs, MedCare-rs, a2ui-rs; (3) no test pins Abduction for + counterfactual; (4) `run_branching`'s fallback arm refuses PROC_DEF; (5) + `Vocabulary` exposes `body_refs` to the interpreter. +S4 cascade: list every file/test/doc/board row that must change for each H, + split mandatory vs follow-up; cross-repo order (OGAR before lance-graph?). +S5 different views: strongest alternative reading for H1 (should NarsVocabulary + win?), H5 (fix kernels instead?), H6 (keep Abduction and make the replay + path −1?); and one second-order consequence per item. No redesigns. + +Output contract per savant: ≤10 findings, each `(Q#, CONFIRMS | VIOLATES | +GAP | PRIOR-ART-AT | RISK, file:line, ≤2 sentences)`.
