feat: cognitive-shader-driver — BindSpace + shader integration#204
Conversation
bitpacked_to_fingerprint() and fingerprint_to_bitpacked() bridge holograph's BitpackedVector (16K) ↔ ndarray Fingerprint<256>. Same backing store, different types. Zero-copy via from_words. https://claude.ai/code/session_01SbYsmmbPf9YQuYbHZN52Zh
QW1+QW2: bitpacked_to_fingerprint() / fingerprint_to_bitpacked() QW7: spo/mod.rs, bulk similarity() → unwrap_or(0.0) fix SPO: 26 errors remain (BindSpace stubs needed), gated behind wip All 7 quick wins addressed. Grammar + world compile clean. https://claude.ai/code/session_01SbYsmmbPf9YQuYbHZN52Zh
…t-of-arrays Role reversal: CognitiveShader no longer sits below thinking-engine. It drives the cycle: reads BindSpace columns (struct-of-arrays with packed u32 MetaColumn prefilter), dispatches bgz17 O(1) cascade through 8 predicate planes, emits cycle_fingerprint + CausalEdge64 through EmbedAnything-pattern commit sinks. New crate: cognitive-shader-driver (16 tests) - bindspace.rs: FingerprintColumns, EdgeColumn, QualiaColumn, MetaColumn - driver.rs: ShaderDriver + CognitiveShaderBuilder (fluent API) - auto_style.rs: 18D qualia → style ordinal (auto-detect) New in lance-graph-contract (zero-dep DTOs): - cognitive_shader.rs: ShaderDispatch→ShaderResonance→ShaderBus→ShaderCrystal - MetaWord(u32): thinking(6b)+awareness(4b)+nars_f(8b)+nars_c(8b)+free_e(6b) - MetaFilter, ShaderSink trait, CognitiveShaderDriver trait - 8 tests passing https://claude.ai/code/session_01SbYsmmbPf9YQuYbHZN52Zh

There was a problem hiding this comment.
run() currently stores row (the source row being iterated) in each ShaderHit, even though shader.cascade() returns matched target indices per hit. This causes top-k to rank repeated copies of the query row instead of actual matches, and cycle_fingerprint then folds the wrong BindSpace fingerprints. Any dispatch where cascade returns targets different from the query row will produce incorrect resonance and cycle outputs.

There was a problem hiding this comment.
In EmitMode::Persist, persisted_row is always taken from top_k[0].row, but top_k is zero-initialized when no hits pass filtering/cascade. This means an empty result set can incorrectly report persisted_row = Some(0), which can falsely signal a commit to row 0 when the dispatch actually found nothing (e.g., strict prefilter, empty layer mask, or tiny radius).

Edge emission casts h.row (u32 BindSpace row id) to u8 for CausalEdge64::pack, which wraps for row IDs above 255. In larger BindSpaces this silently aliases many distinct rows to the same edge indices, corrupting emitted edge provenance and downstream retrieval based on those packed indices.

Adds four append-only bookkeeping files that work as a self-organizing kanban / audit log so nothing falls through the cracks between sessions. Files: 1. EPIPHANIES.md — date-prefixed insight log. Reverse chronological. Every "aha" gets a YYYY-MM-DD entry with Status (FINDING / CONJECTURE / SUPERSEDED). Seeded with the 12 most recent epiphanies from this session; prior-art files (linguistic- epiphanies, cross-repo-harvest, integration-plan, session- capstone) cross-referenced as historical substrate. 2. ISSUES.md — bugs / regressions / invariant violations. Double- entry: Open Issues section + Resolved Issues section. Status transitions flip in place (Open row stays for chronology); Resolution line appends on close. 3. IDEAS.md — architectural speculation. Triple-entry: Open Ideas + Implemented Ideas + Integration Plan Update Log + Rejected/ Deferred. Each shipped idea gets an audit trail from speculation -> code -> plan consequence. 4. TECH_DEBT.md — knowingly-deferred work (shortcuts, stubs, missing probes, hardcoded thresholds). Double-entry: Open Debt + Paid Debt. Seeded with 5 concrete debts from PRs #204-#211 (ContextChain non-Binary16K coherence, CausalityFlow 3/9 slots, NER gap, FP_WORDS=160 migration, Abduction threshold calibration). ## Kanban discipline Every entry in ISSUES / IDEAS / TECH_DEBT carries: - Priority: P0 blocker / P1 high / P2 medium / P3 low. - Scope: @<agent-name>, D<N> plan-id, domain:<tag>. Agents filter by their own @-mention. Nothing gets buried because every ticket has an owner named. ## Permission semantics flip (ask on Write, not Edit) permissions.ask in .claude/settings.json now gates Write (full overwrite) instead of Edit. Method hierarchy documented across BOOT.md, concepts.md, SKILL.md: 1. APPEND (preferred) — new dated row via Edit-prepend or Bash cat >>. No prompt. Double-bookkeeping. 2. Edit field with prior Read — Status flip, Confidence update. No prompt. Prior Read is workspace discipline. 3. Write (full overwrite) — prompts for approval. Escape hatch. Rule: when in doubt, APPEND. All 8 bookkeeping files now follow the same rule: PR_ARC_INVENTORY, LATEST_STATE, STATUS_BOARD, INTEGRATION_PLANS, EPIPHANIES, ISSUES, IDEAS, TECH_DEBT. BOOT.md + CLAUDE.md + cca2a/SKILL.md + cca2a/concepts.md all updated with the unified 8-file table + method hierarchy + kanban fields.
