Story Crater Bot	d8ef4c6349	refactor: PromptBuilder now uses pluggable OptimizerService ... Refactored PromptBuilder to support both legacy (sync) and new (async) optimization paths: Legacy (backward compatible): - cache_metrics() still uses sync ContextOptimizer - build_cache_aligned() unchanged, no optimization New (pluggable OptimizerService): - cache_metrics() falls back gracefully to ContextOptimizer - NEW: build_cache_aligned_async() uses pluggable service - Custom optimizers now work in prompt building Architecture Benefits: ✅ Generic registry optimization works everywhere (ingest + query) ✅ Same codebase supports multiple compressors ✅ Async-aware for production query paths ✅ Backward compatible (no breaking changes) Usage in query_executor: Tests: All 14 prompt tests passing (no changes to test surface)	2026-08-28 12:35:50 -07:00
Story Crater Bot	a854ea69e4	feat: M3.8.2 cache aligner integration — metrics + headers (3 tests) ... CacheMetrics struct (40 LOC): - stable_prefix_bytes, dynamic_tail_bytes - drift_metric (0.0-1.0 ratio) - cache_eligible flag (drift < 0.3) - compression_ratio() and header_* methods PromptBuilder::cache_metrics() (40 LOC): - Calculates cache alignment metrics for query+chunk pairs - Integrates CacheAligner output - Gets compression ratio from ContextOptimizer - Used for HTTP headers and observability HTTP headers ready for client integration: - X-Cache-Stable-Bytes - X-Cache-Drift - X-Cache-Eligible - X-Compression-Ratio 3 new tests: - test_cache_metrics_stable_query - test_cache_metrics_compression_ratio - test_cache_metrics_header_drift Total: 117 mem-core tests (114 before + 3 new)	2026-08-28 10:05:45 -07:00
Story Crater Bot	a45263410f	feat: add cache-aligned prompt builder for LLM API cost savings ... PROBLEM: - PromptBuilder.build() puts everything in a single user message - System + query + memory + chunk all change together - LLM prompt caching gets 0% hits (entire message differs per call) - For a 50-chunk ingestion run, we pay full input price 50 times SOLUTION: PromptBuilder.build_cache_aligned() - Splits prompt into 3 separate messages: 1. SYSTEM: instructions (stable across ALL calls) → CACHED 2. USER[0]: query/problem (stable per run) → CACHED 3. USER[1]: memory + chunk (varies per call) → not cached - Cache prefix (system + query) reused across all chunks in a run - Estimated 30-70% cache hit ratio depending on chunk sizes - ~50% input token cost savings for multi-chunk ingestion TEMPLATES: - templates/gru-mem-system.txt (instructions only, 840B) - templates/gru-mem-query.txt (problem wrapper, 29B) - templates/gru-mem-turn.txt (memory + section, 57B) - templates/gru-mem.txt (legacy, unchanged) API: - PromptBuilder::build() — legacy, backward compatible - PromptBuilder::build_cache_aligned() → PromptMessages - PromptMessages.cache_prefix_tokens() — cacheable token count - PromptMessages.total_tokens() — total estimated tokens - PromptMessages.headroom() — tokens available for response TESTS: 11 unit + 3 integration = 14 new tests - test_cache_aligned_produces_two_user_messages - test_cache_prefix_is_stable_across_chunks - test_cache_prefix_is_stable_across_memory_changes - test_cache_prefix_tokens_positive - test_headroom_positive_under_budget - test_legacy_build_still_works - test_cache_aligned_contains_query - test_cache_aligned_memory/chunk_budget_exceeded - a8_cache_prefix_stable_across_50_chunks - a9_cache_aligned_headroom - a10_cache_savings_estimate TOTAL: 64 mem-core tests passing (52 unit + 12 integration)	2026-08-28 08:24:38 -07:00
