From 9bd66d93cb1b067afc1a118cccd5cb309d6ad743 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 16 May 2026 00:24:55 +0000 Subject: [PATCH 1/5] specs(sprint-10): 4 worker patches for cognitive-substrate-convergence-v1 prep (W4/W6/W7/W10) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Sprint-10 spec corpus patches reflecting decisions locked by PR #380 (cognitive-substrate-convergence-v1 plan). Four CCA2A Sonnet workers completed cleanly in this first wave: W4 — pr-ce64-mb-3-bindspace-efgh.md (~53 LOC): - D-CSV-5 QualiaColumn migration (5a sibling + 5b cutover) cross-ref - i4-16D Wisdom × Staunen → Magnitude SIMD note - AwareOp deferral made explicit as sprint-12+ carry-over - §13 cross-refs to substrate plan W6 — pr-ce64-mb-5-mailbox-soa-attentionmask.md (~159 LOC): - §13 cross-references to substrate plan (CSI-2 g_slot_at_drop + spatial-temporal accumulator semantics already in prior pass) W7 — pr-ce64-mb-6-sigma-tier-router.md (~220 LOC): - Σ10 Rubicon-resonance dispatch logic (delta_f < threshold AND resonance > rubicon_bar; per plan §10.1) - Integer-SIMD MUL evaluation (i4 × i4 → i8 products) replacing f32 - OQ-CSV-6 (Jirak-derived threshold) as sprint-12 D-CSV-10 gate - Plasticity preserved in edge (L-8) confirmed - §15 cross-refs to substrate plan W10 — sprint-10-pr-dep-graph.md (~95 LOC): - C-7 in §"Cross-spec consistency checks" — CSI-1..5 resolutions - §"Successor plan reference" → cognitive-substrate-convergence-v1 - Wave 0.5 (PR-J1-INT4-32D-ATOMS) + Wave 3 (CAM-PQ wiring) added in prior pass Plus 4 worker scratchpads at .claude/board/sprint-log-csv-prep/agents/. Still in flight (will land in follow-up commit): W2 re-dispatch — pr-ce64-mb-2-causaledge64-v2.md W3 re-dispatch — pr-ce64-mb-2-pal8-nars-regression.md W5 — pr-ce64-mb-4-arigraph-spo-g.md (re-dispatch needed; reported permission-denied before settings.local.json fix) W11 — sprint-10-test-plan.md (worker went off-script; will re-dispatch) Process notes: - Permission system fix: replaced Edit(**)/Write(**)/MultiEdit(**) with tool-only form Edit/Write/MultiEdit (per schema's "Tool only: allows all operations of this tool" syntax). The parenthesized-wildcard form was parsed as exact-match for literal "**", not as a tool-wide wildcard. - W11 agent went off-script and modified tracked .claude/settings.json adding cargo+nightly permissions; reverted in this commit.

Entire EdgeColumn can be swept for direction distribution in one AVX2 +pass over `[i8; N]` (pairs of 4-bit lanes packed to i8 for SIMD efficiency). + +**Win 2 — palette × mantissa propagation stays in register family.** The three SPO palette indices +are u8 (bits 0-23); the mantissa is i4 (bits 46-49). Products of palette-distance lookups +(`u8 × i4 → i8` via sign-extend + multiply) stay within the i4/i8/i16 family — no f32 conversion +needed. Qualia dimension products (`QualiaI4_16D × InferenceMantissa`) are similarly `i4 × i4 → i8`, +one SIMD multiply per 16-dim row. This enables the MUL evaluation (DK / TrustTexture / FlowState / +GateDecision) to run entirely in integer SIMD per locked decision L-18. + +**Win 3 — 8-channel thinking-engine transcoder is a near-bitcast at L3 commit.** The +`thinking_engine::CausalEdge64::net_strength()` already returns a signed value whose `signum()` +maps directly to the inference mantissa sign bit, and whose magnitude maps directly to the base rule +index (per the 8-channel → SPO-palette reunion, Option R-3 in synergies doc). The L3 commit +transcoder (`transcode_to_spo()`) is therefore: + +``` +mantissa_sign = net_strength.signum() // forward vs backward +mantissa_mag = channel_to_rule_index(channel) // which of 8 base rules +mantissa_i4 = sign_extend(mantissa_sign * mantissa_mag, 4) +``` + +This is 3 arithmetic operations per edge, no table lookup, no float. The "near-bitcast" claim from +cognitive-substrate-convergence-v1.md §3.1 is literal: both sides share the same signed integer +algebra; the transcoder is an algebra homomorphism, not a format conversion. + +### PR-LL-1 absorption at Reserved5/6 + +PR #375 (PR-LL-1) added `Intervention` and `Counterfactual` variants to `nars_dispatch.rs` only. +Per L-9, these absorb into `Reserved5`/`Reserved6` of the canonical `causal_edge::InferenceType` +when v2 ships.

W2 must clarify the reclaim strategy. Options: (a) shorten temporal from 12 to fewer bits (breaking if existing edges use temporal > the new max); (b) compress direction+inference+plasticity (9 bits, potentially expressible in 7 if some inference types are merged); (c) add a mode-switch where temporal semantics change under the feature flag. W3's `test_temporal_in_msb_gives_sort_order` (in `edge.rs`) will fail if temporal is shortened without updating that test. **This is the highest-priority open question.** +1. **[RESOLVED 2026-05-16] OQ-PAL8-FORMAT — Reclaim target in edge.rs**: Resolved by `cognitive-substrate-convergence-v1.md` §6 (Option F). The reclaim strategy is: **drop temporal (−12 bits)** per decision L-2 ("temporal causality is structural" doctrine — time is carried by chain-position + AriGraph anchor, not stored in the edge). This recovers bits 52-63 without any shortening of direction/inference/plasticity. Spend: InferenceType expansion 3b→4b signed i4 (+1 bit, bits 46-49, L-4), W slot +6b (bits 53-58, L-6), Truth-band lens +2b (bits 59-60, L-7) = 9 spent, 3 spare (bits 61-63). **Bit layout: signed mantissa 4b (bits 46-49), no temporal, W slot 6b (bits 53-58), lens 2b (bits 59-60).** W3's `test_temporal_in_msb_gives_sort_order` must be removed/replaced — temporal no longer exists in the v2 layout. See §11 `test_temporal_absent` which verifies the drop was complete. 2. **TrustTexture import path**: The tests reference `TrustTexture` from `causal_edge::TrustTexture`. If W2 re-exports it from `lance-graph-contract::mul::TrustTexture` (preferred — contract is the canonical zero-dep home), the tests need `use lance_graph_contract::mul::TrustTexture` or the re-export path. Confirm whether `causal-edge` re-exports or defines its own. Defining a new enum breaks the "contract is canonical" doctrine (CLAUDE.md §The AGI-as-glove doctrine). Recommend re-export. 3. **`pack_v2()` vs setter-only API**: The tests assume W2 provides either a `pack_v2()` constructor or that `pack()` + individual setters (`set_g_slot()`, `set_w_slot()`, `set_truth()`) is the complete v2 API. The setter-only approach is simpler and avoids a new constructor signature. If W2 uses only setters, `pal8_v2_v2_round_trip_all_fields` should be revised to call `pack()` + three setters rather than a hypothetical `pack_v2()`.

(G-slot dropped per L-3 — no G accessor, no `G_SHIFT`.) - **W3** owns: the regression tests in this spec that prove W2 didn't break things; CI workflow extension; this spec file. **Bit-position TBD protocol:** W3's tests use feature-flag guards (`#[cfg(feature = "causal-edge-v2-layout")]`) so they compile and pass on the v1 codebase before W2's changes land. The `pal8_v1_v2_round_trip_zero_default` test has a non-gated section that exercises the v1 `pack()` API — this passes on both v1 and v2 builds. Meta-reviewer reconciles the concrete bit positions from W2's spec against W3's test assertions before implementation. **If W2 spec not yet produced** (as of this draft): bit-position references throughout cite "TBD — defer to W2's bit-layout table." All tests are written against functional properties of the accessor functions, not raw bit masks. They will remain correct once W2 supplies the concrete layout. -**Agreement checklist (meta-reviewer task):** +**Agreement checklist (meta-reviewer task) — v2 Option F layout:** -1.

If W2 re-exports it from `lance-graph-contract::mul::TrustTexture` (preferred — contract is the canonical zero-dep home), the tests need `use lance_graph_contract::mul::TrustTexture` or the re-export path.

The setter-only approach is simpler and avoids a new constructor signature. If W2 uses only setters, `pal8_v2_v2_round_trip_all_fields` should be revised to call `pack()` + three setters rather than a hypothetical `pack_v2()`.
