From 7d7b5377f5844952496cfe44351b9283bb96ecaf Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 16 May 2026 10:49:41 +0000 Subject: [PATCH 1/6] =?UTF-8?q?WIP(sprint-12/wave-G):=20in-flight=20snapsh?= =?UTF-8?q?ot=20=E2=80=94=20W-G1=20bindspace=20+=20W-G2=20witness-corpus?= =?UTF-8?q?=20+=20W-G3=20mul.rs=20i4=5Feval=20batch=20API?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In-flight worker outputs from Wave G fleet (6 Sonnet workers). Workers may continue writing to these files; subsequent commits on this branch finalize the deliverables when completion notifications arrive. W-G1 (D-CSV-5b QualiaColumn cutover) — bindspace.rs (+65 LOC diff so far): likely still mid-flight; tests at file tail still read both `bs.qualia` (f32) AND `bs.qualia_i4` (i4) suggesting the cutover isn't complete yet. W-G2 (D-CSV-6b CAM-PQ wiring) — witness_corpus.rs (+386 LOC): substantial expansion of the WitnessCorpus index. Awaiting completion report for the final test pass count. W-G3 (D-CSV-13 SIMD vec batch API) — mul.rs (+219 LOC): new `pub mod batch` inside `i4_eval` with parallel-arrays batch functions for the 5 MUL evaluators. Stop-hook driven snapshot commit. Final aggregation + clippy + test verification arrives in subsequent commits per worker completion order. https://claude.ai/code/session_01UwJuKqP828qyX1VkLgGJFS --- .../cognitive-shader-driver/src/bindspace.rs | 65 +-- crates/lance-graph-contract/src/mul.rs | 219 ++++++++++ .../src/graph/arigraph/witness_corpus.rs | 386 ++++++++++++++++-- 3 files changed, 618 insertions(+), 52 deletions(-) diff --git a/crates/cognitive-shader-driver/src/bindspace.rs b/crates/cognitive-shader-driver/src/bindspace.rs index 1663b6b43..b1cbc20e9 100644 --- a/crates/cognitive-shader-driver/src/bindspace.rs +++ b/crates/cognitive-shader-driver/src/bindspace.rs @@ -129,15 +129,18 @@ impl EdgeColumn { #[inline] pub fn set(&mut self, row: usize, edge: u64) { self.0[row] = edge; } } -/// 18 × f32 per row.

charset=UTF-8 Content-Transfer-Encoding: 8bit W-G1 (D-CSV-5b QualiaColumn cutover) — FINAL - bindspace.rs: cutover complete. BindSpace.qualia is now QualiaI4Column (8 B/row, was 72 B/row). QualiaColumn struct kept with #[deprecated] for one release cycle. - driver.rs: 2 qualia READ call sites updated. Line 148 (style resolver seed) now calls `bs.qualia.row(row).to_f32_17d()` → `[f32; 17]` for `auto_style::resolve`. Line 398 (alpha-composite closure) pre- materializes `Vec<(u32, [f32; 17])>` for hits before closure capture. - engine_bridge.rs: dispatch_busdto drops the double-write; single i4 write at the engine boundary via `from_f32_17d(&q17)`. unbind/ read_qualia_decomposed/write_qualia_observed call `.to_f32_17d()` at read sites. classification_distance (dim 17, no longer stored) returns 1.0 default. - 5 new D-CSV-5b tests in bindspace; 4 pre-existing tests updated for new shape (footprint byte count 71785→71713; builder tests adjusted for new push_typed signature; 2 engine_bridge round-trip tolerances relaxed to i4 precision ±0.15) - end_to_end.rs: 1 integration test updated to use the new i4 surface - Test status: **86/86 pass, 0 fail.** W-G4 (D-CSV-15 Σ10 Jirak threshold) — math correction - Σ_k = k^(p/2) / 10^(p/2). For p=3 (workspace CAM-PQ regime per I-NOISE-FLOOR-JIRAK), Σ_1 ≈ 0.0316, Σ_5 ≈ 0.3536, Σ_10 = 1.0. - Worker caught a math error in my spec: "p ≥ 4 collapses toward linear" is INVERTED. p=4 produces MORE convex spacing (delta variance p=3 → 0.00079; p=4 → 0.00267). Test test_jirak_p_4_more_linear was rewritten to assert the actual mathematical behavior. - Default() now calls jirak_p(3.0); hand_tuned() preserves the sprint-11 linear values; default_bands() deprecated 0.2.0. - 20/20 tests pass (12 original + 8 new).

The original name pre-committed to CAM-PQ distance- ranking semantics that the HashMap backing doesn't deliver. The doc comment is honest ("HashMap-backed; sprint-13+ upgrades to real ndarray::hpc::cam_pq"), but the type name would mislead at consumer call sites. Sprint-13+ adds `WitnessIndexCamPq` with the real codec wiring; the HashMap variant becomes the fallback for environments without ndarray CAM-PQ support. **CSI-7 follow-through:** Verified sigma-tier-router has NO self- declared [workspace] table; cargo metadata --no-deps shows both sigma-tier-router AND cognitive-shader-driver in the workspace (16 packages total). Opus's note about pending follow-through was unwarranted — it's already done. **CSI-18 (MED):** Four iron rules now share a meta-pattern ("do X consistently across the codebase; document deviations explicitly"). Sprint-13 should land `.claude/knowledge/iron-rules-doctrine.md` consolidating this meta-pattern so future iron rules fit the template intentionally. W-Meta-Opus standout call-out W-G4 noticed my brief was inverted, consulted the I-NOISE-FLOOR-JIRAK iron rule, derived the correct math (Σ_k = k^1.5 / 10^1.5 with Σ_1 ≈ 0.031623 and Σ_10 = 1.0 exactly), and shipped 8 new tests with the corrected assertion in test_jirak_p_4_more_linear. Jirak 2016 citation present in both module-level and method-level doc comments. Sprint-13 spawn recommendation: YES, gated on Wave G merge + sprint-13 worker template that bakes lib.rs/workspace registration INTO worker scope (Wave F CSI-13 has now been validated as a recurring failure mode unless main thread enforces it pre-spawn). Pre-existing infra issue: local `cargo test -p lance-graph` hit ENOSPC during link (workspace target/ disk pressure). Mechanical 12-instance rename did not require local re-test; CI validates. https://claude.ai/code/session_01UwJuKqP828qyX1VkLgGJFS --- .../sprint-log-11/meta-review-opus-wave-g.md | 180 ++++++++++++++++++ crates/lance-graph/src/graph/arigraph/mod.rs | 2 +- .../src/graph/arigraph/witness_corpus.rs | 24 +-- 3 files changed, 193 insertions(+), 13 deletions(-) create mode 100644 .claude/board/sprint-log-11/meta-review-opus-wave-g.md diff --git a/.claude/board/sprint-log-11/meta-review-opus-wave-g.md b/.claude/board/sprint-log-11/meta-review-opus-wave-g.md new file mode 100644 index 000000000..6cbe05a5b --- /dev/null +++ b/.claude/board/sprint-log-11/meta-review-opus-wave-g.md @@ -0,0 +1,180 @@ +# Sprint-12 Wave G Meta-Review — OPUS Honest Cross-Cutting Review (Opus 4.7, W-Meta-Opus, 2026-05-16) + +> **Scope:** Independent Opus review of sprint-12 Wave G fleet (6 Sonnet workers, 4 commits on top of main `b526485`).

Executive Summary + +### Wave G grade: **A−** +### Sprint-12 grade-so-far: **B+** (Wave F integration debt + Wave G follow-through = net positive trajectory) + +**Headline:** Wave G is the discipline correction Wave F earned. The six workers shipped the QualiaColumn cutover (D-CSV-5b), the CAM-PQ-indexed WitnessCorpus (D-CSV-6b HashMap surface), the i4 batch evaluation API (D-CSV-13 scaffolding), the Jirak-derived Σ-tier thresholds (D-CSV-15 partial — math derivation done; principled VAMPE pairing still sprint-13+), the I-LEGACY-API-FEATURE-GATED iron-rule promotion, and the one-line cognitive-shader-driver workspace fix. **All six workers stayed in lane.** No new CSI-7/8/9-class blockers materialized. The workspace fix (W-G6) and the Jirak math correction (W-G4) both materially exceed the floor a Sonnet worker is expected to hit. + +**Why A− not A:** + +- W-G2 ships `CamPqWitnessIndex` (the name pre-commits to CAM-PQ semantics) but the backing store is a `HashMap>` placeholder. The naming/implementation mismatch is acknowledged in the doc comment but the name will read as load-bearing once consumers attach. (CSI-15 below.) +- W-G3's `mul_assess_vec` convenience wrapper allocates inside the loop; this is consistent with its `_vec` name but worth flagging because the surrounding 5 `_batch` functions are explicitly SIMD-shaped. The `_vec` wrapper has only ONE length assert (qualia/mantissas), not two — but it allocates the output, so the second assert isn't applicable. Correct as designed; the cross-cutting finding is naming hygiene (CSI-16). +- The eight new W-G4 Jirak tests are good, but the test that compares `jirak_p(4.0) > jirak_p(3.0)` uses variance of inter-tier deltas as a convexity proxy. That is a reasonable surrogate but not a Jirak-mathematical statement; the test would pass for any α>1 spacing. Not wrong, just under-claims the spec's "p ≥ 4 asymptotically iid" assertion. + +**Why not A:** Wave G is not just clean delivery; it actively repaired three Wave F gaps: +1. W-G6 fixes `TD-SHADER-DRIVER-WORKSPACE-CONFLICT-1` (moves cognitive-shader-driver from `exclude` to `members` — the same issue I called out as CSI-7's structural sibling). +2. W-G5 promotes E-META-10 to iron rule `I-LEGACY-API-FEATURE-GATED` per my Wave F §4 recommendation — the recommendation was explicit and was acted on. +3. W-G1 completes the D-CSV-5b cutover end-to-end (bindspace.rs, engine_bridge.rs, driver.rs all touched in a single coordinated commit) — this is exactly the "main-thread aggregation pass" pattern Wave F botched. + +--- + +## 2. Per-Worker Grade Table + +| Worker | Grade | Key finding | +|---|---|---| +| **W-G1** | **A−** | QualiaColumn → QualiaI4Column cutover lands cleanly across `bindspace.rs` (BindSpace.qualia field + Builder + 5 new D-CSV-5b tests), `engine_bridge.rs` (dispatch_busdto + write_qualia_observed + read_qualia_decomposed all convert at boundary via `.to_f32_17d()` / `from_f32_17d()`), `driver.rs` (qualia reads converted at the call site, alpha_composite hit_qualia_f32 pre-materialized for closure lifetime). `QualiaColumn` is correctly marked `#[deprecated(since = "0.2.0")]` with migration pointer. 18 tests in bindspace.rs (was 13 pre-cutover) — net +5 i4 tests, no test loss. CSI-14 check below: ALL non-test/non-comment QualiaColumn references in the crate are in deprecation context (the from_f32 bulk converter + the meta-test verifying the deprecation attribute is present). No leftover live f32 qualia writes. | +| **W-G2** | **B+** | WitnessCorpus CAM-PQ-indexed HashMap surface is functionally correct (15 tests; iter / query / cam_pq_search / evict_stale_before / Arc-CoW all green). The doc comment correctly cites the upstream blocker (ndarray::hpc::cam_pq operates on 256D+ float vectors / GraphHV, not u64 SPO → Vec). Module is registered in `arigraph/mod.rs` (`pub mod witness_corpus; pub use witness_corpus::{CamPqWitnessIndex, WitnessCorpus, WitnessEntry, WitnessId};` — discipline that the Wave F equivalents failed at). **Downgrade reason:** the type name `CamPqWitnessIndex` (CSI-15) pre-commits to CAM-PQ semantics that the HashMap doesn't have. A real CAM-PQ index would rank by distance from a query SPO vector; this returns insertion order. The doc says so honestly, but the name will mislead future consumers. | +| **W-G3** | **A−** | Five batch functions (`dk_position_batch`, `trust_texture_batch`, `flow_state_batch`, `gate_decision_batch`, `mul_assess_batch`) + one `mul_assess_vec` convenience wrapper. All five `_batch` functions take parallel `&[A]`, `&[B]`, `&mut [C]` slices with TWO length asserts each (qualia/mantissas + input/output). The single-input `trust_texture_batch` correctly has only ONE assert (no mantissas). The `_vec` wrapper allocates and has only one assert as expected. Zero allocations in the 5 hot-path batch functions. 6 batch tests + 1 length-mismatch panic test + 1 empty-input test. The contract is exactly what AVX-512 lane intrinsics target. | +| **W-G4** | **A** | Worker corrected my spec error. The original (Wave F → Wave G) brief said "p ≥ 4 collapses linear"; that was inverted. The correct Jirak 2016 statement is: rate is `n^(p/2-1)` for `p ∈ (2,3]`, and `n^(-1/2)` in L^q for `p ≥ 4`. The worker derived `Σ_k = k^(p/2) / 10^(p/2)`, normalized so Σ10 = 1.0 exactly. **Spot-check verified:** for p=3, Σ1 = 1/10^1.5 ≈ 0.031623 (matches `test_jirak_default_endpoints`), Σ5 ≈ 0.353553, Σ10 = 1.0 (anchored). The Jirak 2016 citation (arxiv 1606.01617) is present in both the module-level doc comment (line 16) AND the `jirak_p` method doc comment (line 100). `Default::default()` returns the Jirak-derived bands; the sprint-11 hand-tuned linear values are preserved as `SigmaTierBands::hand_tuned()` for backwards comparison. 12 pre-existing tests + 8 new Jirak tests = 20 total. All 12 pre-existing tests use `default_bands()` (now marked `#[deprecated]`) under `#[allow(deprecated)]` — disciplined backwards compatibility. | +| **W-G5** | **A** | (1) CLAUDE.md now has FOUR iron rules: I-SUBSTRATE-MARKOV, I-NOISE-FLOOR-JIRAK, I-VSA-IDENTITIES (all sprint-11) + the new I-LEGACY-API-FEATURE-GATED (this PR). The new rule is well-scoped (it specifies the 5 codex P1 catches by number, mandates field-isolation matrix tests at layout-bit boundaries, and points to E-META-10 + CSI-2 + the i4-substrate-decisions knowledge doc). (2) EPIPHANIES.md E-META-10 has the "PROMOTED to iron rule" header in the **Status (2026-05-16):** line — append-only discipline preserved. (3) TECH_DEBT.md now has TD-LEGACY-API-FEATURE-GATED-RESOLVED-1 at the top, marking the resolution chain. The main-thread consolidation (worker initially wrote to repo-root TECH_DEBT.md; main thread moved it to `.claude/board/TECH_DEBT.md`) is exactly the kind of aggregation Wave F was missing. | +| **W-G6** | **A−** | One-line resolution to TD-SHADER-DRIVER-WORKSPACE-CONFLICT-1: moved `crates/cognitive-shader-driver` from `exclude` to `members` in `Cargo.toml` with a comment citing the TD ticket. This unblocks `cargo build -p cognitive-shader-driver` from workspace root — the same friction class as CSI-7 (sigma-tier-router). Grade is A− not A only because the symmetric fix for sigma-tier-router (CSI-7 from Wave F) is not in this PR — it's queued for a separate aggregation commit. The crate moved IS in the workspace `members` list now. | + +**Test count rollup:** Total #[test] markers across the six modified files: **99**. Breakdown: bindspace.rs 18, sigma-tier-router 20, mul.rs 23 (8 batch + 15 i4_eval scalar), witness_corpus.rs 15, engine_bridge.rs 10, driver.rs 13. Per-worker test additions versus pre-Wave-G baseline: W-G1 added 5 (D-CSV-5b cutover), W-G2 added 7 (CamPqWitnessIndex + index-aware query/evict tests), W-G3 added 8 (batch parity + panic + empty), W-G4 added 8 (Jirak math). Wave G test delta: **+28 unit tests** toward the sprint-10 1550 Miri target. + +--- + +## 3. Cross-Cutting Findings (CSI-14..18) + +These extend the CSI-1..13 numbering from sprint-11 / Wave F.

No live code paths. + +**Status:** no fix needed. W-G1 stayed in lane and the cutover is complete in this crate. This is a positive finding — the kind that exposes well-scoped work. + +### CSI-15 (P2) — W-G2's `CamPqWitnessIndex` name pre-commits to CAM-PQ semantics the HashMap doesn't have + +**Files:** `crates/lance-graph/src/graph/arigraph/witness_corpus.rs:101-167` (the type) + `mod.rs:18` (the re-export). + +The type is named `CamPqWitnessIndex` but the backing store is `HashMap>` — a hash bucket from packed SPO to entry positions. A real CAM-PQ index would (a) operate on multi-dimensional vectors not u64 keys, (b) return distance-ranked top-k, and (c) consult the `ndarray::hpc::cam_pq::CamPqCodec`. The current implementation does none of these. The doc comment (lines 90-100) is honest about this: "this PR ships a HashMap-backed index as the canonical surface" and "TECH_DEBT: upgrade `by_spo` HashMap to ndarray::hpc::cam_pq once upstream adds SPO witness-tuple support." + +**Why this matters:** the type is `pub` and re-exported from `arigraph::mod.rs`. Once consumers depend on `CamPqWitnessIndex` as a type name, renaming becomes ABI-breaking. The current `cam_pq_search(spo, k)` method is documented as returning "first k entries in chain order; no distance ranking is applied" — sprint-13+ when ndarray's codec lands, the method semantics will change (distance ranking) but the name will already imply distance ranking, so the "before/after" delta will be silent at the call site. + +**Recommendation:** rename the HashMap-backed type to `WitnessIndexHashMap` (or `WitnessIndexByExactSpo`) and reserve `CamPqWitnessIndex` for the sprint-13+ ndarray-codec backed type. ~30 LOC churn (rename + doc updates + tests). **Sprint-12 P2 housekeeping; the rename is cheaper now than after consumers attach.** This is the kind of premature naming-claim that creates ABI archaeology debt. + +### CSI-16 (CONFIRMED OK) — W-G3 batch API length-assertion discipline is complete + +**Verification:** all FIVE `_batch` functions assert BOTH `qualia.len() == mantissas.len()` AND `qualia.len() == out.len()`: + +- `dk_position_batch` lines 644-646 — two asserts ✓ +- `trust_texture_batch` line 654 — one assert (no mantissas; trust_texture is qualia-only by design) ✓ +- `flow_state_batch` lines 662-663 — two asserts ✓ +- `gate_decision_batch` lines 671-672 — two asserts ✓ +- `mul_assess_batch` lines 680-681 — two asserts ✓ + +The `mul_assess_vec` convenience wrapper at line 689 has only ONE assert (qualia/mantissas) because it ALLOCATES the output (no `&mut [T]` to size-check). The `_vec` naming makes this explicit; no allocations leak into the hot path because the 5 SIMD-shaped functions all take pre-allocated `&mut [T]`. + +**Status:** no fix needed. The original spec language ("all 5 batch functions; verify the panic for length mismatch") is met. There is also a positive `test_batch_panic_on_length_mismatch` test asserting the panic fires. The empty-input test (`test_batch_empty_input_returns_empty_output`) covers the n=0 edge case for all six surfaces. + +### CSI-17 (LOW) — Wave F → Wave G Jirak spec error did not propagate beyond the worker brief + +**Verification:** grep'd the workspace for `Jirak` co-occurring with `p.*4` or `p ?[≥>=]+ ?4`. Results (live code/docs only): + +- `CLAUDE.md:307`: "`n^(p/2-1)` for `p ∈ (2,3]`, `n^(-1/2)` in L^q for `p ≥ 4`" — **CORRECT** statement of Jirak's two regimes. ✓ +- `FormatBestPractices.md:90`: same correct statement. ✓ +- `crates/jc/src/jirak.rs:12-13`: "Jirak's theorem gives the correct rate: n^(p/2-1) for p ∈ (2,3] ... For p ≥ 4 the [classical rate holds]" — **CORRECT**. ✓ +- `crates/sigma-tier-router/src/lib.rs:69`: "`n^(-1/2)` in L^q for `p ≥ 4` (the 'asymptotically iid' regime)" — **CORRECT** (this is W-G4's own derivation). ✓ + +The original "p ≥ 4 collapses linear" framing in my Wave G brief was inverted; the workspace itself (CLAUDE.md, FormatBestPractices.md, jc/jirak.rs) had the correct statement the whole time. W-G4 corrected the brief by reading the workspace's own iron rule, which is exactly the right discipline. + +**Status:** no fix needed. This CSI confirms the worker corrected the spec by consulting CLAUDE.md — the consult-don't-guess pattern worked. **Positive finding.** If the brief had been followed verbatim, the bands would be wrong; the worker's diligence is grade-A behavior. + +### CSI-18 (MED) — Four iron rules now span four axes; doctrine consolidation deferred to sprint-13 + +**Observation:** CLAUDE.md as of HEAD has FOUR iron rules: + +1. **I-SUBSTRATE-MARKOV** — VSA bundling guarantees Chapman-Kolmogorov in d=10000 by construction. (2026-04-20) +2. **I-NOISE-FLOOR-JIRAK** — Bits are weakly dependent; use Jirak 2016 rates not classical Berry-Esseen. (2026-04-20) +3. **I-VSA-IDENTITIES** — VSA operates on identity fingerprints that POINT TO content; never on bitpacked content. (2026-04-21) +4. **I-LEGACY-API-FEATURE-GATED** — v1 API paths under v2-layout features must route through canonical mapping or feature-gate to no-op with migration pointer. (2026-05-16, W-G5) + +Each rule pattern says, in compressed form: **"Do X consistently across the codebase; document deviations explicitly."** The Markov rule says "don't replace bundle with XOR without consulting [FORMAL-SCAFFOLD]". The Jirak rule says "cite weakly-dependent Berry-Esseen, not classical, on every threshold". The VSA-Identities rule says "use the register before reaching for VSA; bundle identities, not content". The Legacy-API rule says "the same function name MUST NOT silently produce different semantics under different feature flags." + +**Emerging meta-rule:** every iron rule formalizes a discipline against silent drift across some axis (substrate operator / statistical model / data semantics / API version). The pattern is the same; only the axis differs. + +**Recommendation for sprint-13:** consolidate doctrinal commentary in a single `.claude/knowledge/iron-rules-doctrine.md` knowledge doc cross-referencing all four rules + the meta-pattern. ~250 LOC of synthesis. The current arrangement (four scattered iron-rule sections in CLAUDE.md + per-rule cross-refs to EPIPHANIES/TECH_DEBT) works but does not surface the meta-pattern that a new iron rule should fit the "no silent drift across axis X" template.

The sigma-tier-router Cargo.toml may still declare a standalone `[workspace]`; verify and remove if so. Wave F left this open. +3. **CSI-9 cross-repo PR** (~4 LOC in ndarray): register `qualia` + `splat_field` in `/home/user/ndarray/src/hpc/stream/mod.rs`. Blocker on D-CSV-11 productization; coordination with AdaWorldAPI/ndarray upstream required. +4. **CSI-18 doctrine doc** (~250 LOC): consolidate the four iron rules into `.claude/knowledge/iron-rules-doctrine.md` to anchor sprint-13 doctrinal workers. + +Items 1+2+4 are local; item 3 is the only true cross-repo blocker. Standing user ratifications from Wave F + Wave G (OQ-CSV-6 Jirak math now done, D-CSV-5b cutover complete, E-META-10 promoted) remain valid. + +--- + +## 5. Final Reflection + +Wave G is what Wave F should have been. Six workers, six in-lane deliveries, three Wave F debt items actively repaired (workspace conflict, E-META-10 promotion, D-CSV-5b cutover follow-through), no new blocker-class regressions. The two soft findings (CSI-15 naming pre-commitment and CSI-16 doctrine consolidation deferred) are sprint-13 housekeeping, not Wave G failures. The Jirak math correction (W-G4) is the standout — the worker noticed the brief was wrong, consulted CLAUDE.md's own iron rule, derived the correct math, and shipped it with eight new tests. That is exactly the consult-don't-guess discipline this workspace's CCA2A pattern is meant to produce. Sprint-13 should pick up CSI-15 / CSI-7-symmetric / CSI-18 / CSI-9 as the four pre-spawn hygiene items, and the doctrinal anchor (CSI-18) should be the first knowledge-doc deliverable so sprint-13's workers have a single place to land "this is how the four iron rules compose." The structural improvement Wave G earned is that the fleet template now demonstrably **can** ship clean integration commits when the worker prompts include the registration discipline — Wave G is the proof.
