docs: Add handover distillation document Complete session handover covering: - Primary roadblock: Lance 1.0 vs 2.1 API mismatch - 3 storage backend options (Redis, PostgreSQL, S3/Lance) - 9 critical race conditions summary with severity - P0 next steps for production readiness - Full context for continuation sessions https://claude.ai/code/session_01CSyicPmyQZ88KUNd2RW3Kk#74

…ures - Add Flight gRPC binary (ladybug-flight) for Arrow Flight server - Wire full CogRedis interface to /redis endpoint (DN.SET, DN.GET, CAM.*, etc.) - Update Dockerfile to enable flight feature and expose port 50051 - Fix Flight module compilation (Bytes conversions, Array trait import, borrow fix) - Export RedisResult from storage module, alias redis_adapter::RedisResult - Enable feature flags in Dockerfile build (simd, parallel, flight) - Note: lancedb feature has API compatibility issues - disabled until fixed The server now supports: - DN.SET Ada:A:soul:identity "content" → Tree traversal commands - CAM.* commands → 4096 CAM operations - DAG.* commands → ACID transactions - Arrow Flight gRPC on port 50051 https://claude.ai/code/session_01CSyicPmyQZ88KUNd2RW3Kk
…sions MUST read CRITICAL SECTION ADDED AT TOP: -⚠️ STOP. READ THIS FIRST. DO NOT SKIP.⚠️ - Clear diagram showing what works vs what's broken - lance_zero_copy/ ≠ lance.rs (MUST understand this) - Feature flags and what they enable - Vendor mismatch explanation (lance 1.0 vs 2.1) Key architecture facts documented: - ArrowZeroCopy works WITHOUT lance crate dependency - lance.rs is OPTIONAL and currently BROKEN - Production path: CogRedis → BindSpace → ArrowZeroCopy - lancedb feature disabled in Dockerfile until lance.rs fixed This documentation exists because previous sessions repeatedly broke things by not understanding what was already built. https://claude.ai/code/session_01CSyicPmyQZ88KUNd2RW3Kk
- STORAGE_CONTRACTS.md: 9 race conditions identified in storage stack - LRU tracker duplicate entries - WAL write-behind (not write-ahead) - WriteBuffer ID allocation race - DependencyGraph partial writes - XorDag parity TOCTOU - EpochGuard work stealing race - TieredStorage eviction race - SnapshotChain length race - TemporalStore conflict detection gap - REWIRING_GUIDE.md: Copy-paste ready fixes for each issue - Before/after code examples - Migration notes - Verification tests - Performance impact analysis - BACKUP_AND_SCHEMA.md: Storage strategy documentation - XOR diff versioning to Redis - S3 integration via LanceDB - Schema safety and graceful migrations - Backup/restore procedures - Disaster recovery runbook - Updated CLAUDE.md with cross-references to new docs https://claude.ai/code/session_01CSyicPmyQZ88KUNd2RW3Kk
- DELTA_ENCODING_FORMATS.md: Multi-format delta encoding specification - FF:FF prefix envelope escape sequence - Format 1: Sparse Bitpacked (16-bit, 2^16 addresses) - Format 2: Float32/32-bit Hamming Delta (FF:FF FF:FF) - Format 3: Non-Sparse 48-bit / 10000D XOR (FF:FF FF:FF FF:FF) - Self-synchronizing format detection - Compression ratio comparisons - Encoding/decoding pipeline - Magic bytes embedded in prefix envelope extend 8+8 model - 0xFF prefix reserved as escape to extended formats - Backward compatible: old readers skip invalid addresses https://claude.ai/code/session_01CSyicPmyQZ88KUNd2RW3Kk
- Use upper nibble of escape byte for format type (12-bit overhead) - Lower nibble is DATA, not wasted (4 bits saved per escape) - Document prefix blocking: 0xFF prefix permanently reserved - Add FF:00 escape sequence for literal 0xFF bytes in payload - Type nibbles: 0=escape, 1=Hamming, B=float, D=dim, E=extended, F=full - 65,280 usable addresses (256 reserved for escapes) https://claude.ai/code/session_01CSyicPmyQZ88KUNd2RW3Kk
- FF:xx addresses can function as feature flags, not just format indicators - Backend writes to multiple prefixes with implicit mode updates - Each write to FF:xx updates corresponding feature's state - Map prefixes to features: 0x=core, 1x=hamming, Dx=sparse, etc. https://claude.ai/code/session_01CSyicPmyQZ88KUNd2RW3Kk

…ctories Wire rustynum PRs #74-81 types into ladybug-rs: - Add rustynum-bnn dependency (CrossPlaneVote, CausalSaliency, HaloType) - hdr_cascade: MexicanHat::from_sigma_gate() replaces hardcoded thresholds with SigmaGate-derived Discovery/Hint bands; AlienSearch::with_sigma_gate() and calibrate_from_sigma(); classify_sigma() + significance_to_signal() bridge - New gestalt module (extensions/spo/gestalt.rs): * GestaltState: Crystallizing/Contested/Dissolving/Epiphany from CausalSaliency * BundlingProposal: tentative/committed/rejected lifecycle via CollapseGate * detect_bundling(): per-plane Hamming analysis → SO/PO/SP halo classification * TiltReport + PlaneCalibration: per-axis σ rotation correction * TruthTrajectory: temporal audit trail with evidence events * CollapseMode: Research/Production/Regulated auto-FLOW thresholds * AntialiasedSigma: continuous σ scoring with soft band boundaries All tests pass.
