v0.8.0

Added

Three-Layer Distillation Pipeline

• Automatic distillation via NullDistiller in ingest pipeline (Layer 1: regex-based, P95 < 5ms)
• Context hook injection for LLM-based extraction at SessionStart (Layer 2: Claude Code as distiller, zero extra cost)
• /distill-transcripts skill for manual deep extraction (Layer 3: on-demand, depth-aware prompts)
• memory.undistilled and memory.mark_distilled MCP tools for distillation tracking
• Hook::DistillationRunner extracted from Handler for context hook injection
• TaskCompleted and TeammateIdle hook events for ingest triggers
• Distillation metrics backfill on database initialization
• Doctor check for undistilled content
• Pending distillation count in memory.status output

Recall Enhancements

• Intent parameter for recall query disambiguation (#3)
• Retrieval score traces for semantic search (#5)
• Configurable embedding providers with dimension checking

Hook Enhancements

• statusMessage on all hooks for descriptive spinner text during hook execution
• StopFailure hook to capture transcript data even on session errors (rate limits, server errors)
• Notification hook with idle_prompt matcher for opportunistic sweep during idle

New Commands & Skills

• install-skill command and memory-recall agent (#8, #12)
• Shell completion command for bash and zsh (#18)

Distillation Benchmark Results

• NullDistiller: Concept Recall 0.952, Fact Precision/Recall 1.000 (31 test cases)
• Claude Code LLM: Concept Recall 0.902 (all 41 cases), 0.900 on semantic cases (vs 0.333 for regex)
• Average 1.6 facts stored per case across LLM extraction
• E2E distillation recall benchmark and extraction quality benchmarks
• Concept-based matching for distiller-agnostic benchmark comparison

Fixed

• --allowedTools added to ClaudeCliRunner for MCP tool permissions
• Test isolation for context hook when global database has facts

Internal

• Extracted RetryHandler and SchemaManager modules from SQLiteStore
• Extracted Recall into engine strategy pattern with DualEngine, LegacyEngine, and shared QueryCore
• Extracted Tools god object into 6 handler modules
• Added 36 specs for 5 previously untested files
• All 3 god objects eliminated, 0 files over 500 lines
