feat: Implement M2.5 & M2.6 — Obsidian vault projector + rebuild orchestrator
M2.5 ✅ Complete: Deterministic vault generation from event log Implementation (crates/mem-store/src/obsidian.rs): - ObsidianProjector::project() reads log → writes vault - Vault structure: - vault/<project>/index.md — L2 synthesis, links all L1 - vault/<project>/<query-id>.md — L1 per standing query - vault/<project>/evidence/<source>-<t>.md — L0 (optional) - Frontmatter rendering with stable key order (BTreeMap) - `updated` from log (not now()) — deterministic rebuilds - Sorted provenance section (by source, then t) - Empty memory still writes with "_No evidence found_" note - Bidirectional links: L1↔L2 via [[query-id]] and [[index]] - Write with \n line endings, no trailing whitespace, exactly 1 final newline Types: - MemoryRecord: {level, project, query_id, text, updated, run_id, t, source, parents} - MemoryParent: {source, t, description} - ProjectorOpts: {emit_evidence_notes} - ProjectorStats: {files_written} Tests (10 integration tests in tests/it_projector.rs): 1. a1_byte_identical_twice — multiple renders are byte-equal 2. a2_no_generation_timestamp — no now() leakage 3. a3_frontmatter_key_order — stable alphabetical order 4. a4_golden_structure — complete section presence 5. a5_empty_memory_still_writes — explicit fallback text 6. a6_links_bidirectional — L1↔L2 linkage 7. a7_evidence_notes_rendering — L0 note format 8. a8_line_endings_and_newline — \n only, 1 trailing 9. a9_provenance_sorted — source then t order 10. a10_no_trailing_whitespace — deterministic formatting M2.6 ✅ Complete: Rebuild orchestration from event log Implementation (crates/mem-store/src/rebuild.rs): - RebuildEngine::new(db_url) with Postgres pool - RebuildEngine::rebuild(opts) — full orchestration - Four-step process: 1. Clear project (nodes cascade → edges) 2. Read log memories → convert to MemoryNodes 3. Upsert all nodes (ON CONFLICT DO NOTHING) 4. Insert all edges (two-pass: nodes then edges) 5. Project vault (M2.5) - Three rebuild modes: - Default: both database + vault - --vault-only: skip database operations - --db-only: skip vault projection - Incomplete log detection (no run_end) — error by default - --allow-partial flag to proceed anyway - Embedding cache by content sha256 - Keyed on memory text hash (not node id) - Survives runs, reduces recomputation - Statistics reporting: nodes by level, edges, embeddings cached/computed Types: - RebuildOpts: {project, vault_only, db_only, allow_partial, cache_dir, vault_dir, log_dir} - RebuildStats: {nodes_l0, nodes_l1, nodes_l2, edges, embeddings_computed, embeddings_cached} - Content identity via sha256(memory.text) Tests (6 integration tests in tests/it_rebuild.rs): 1. a1_from_empty — rebuild creates expected node counts 2. a2_idempotent_db — rebuild twice = same row counts 3. a3_idempotent_vault — rebuild twice = byte-identical files 4. a5_embedding_cache_reduces_computation — cache lookup works 5. a6_incomplete_log_refused — no run_end → error unless --allow-partial 6. a7_memory_sha_content_identity — same text = same hash 7. a8_rebuild_opts_modes — mode flags work correctly Dependency: - crates/mem-store/Cargo.toml: added sha2 (workspace) Updated INDEX.md: - M2.x: 6/8 done (M2.7, M2.8 remain) - Total: 48✅ + 2🟡 + 23⬜ (was 45✅) - 26 new tests (M2.5: 10, M2.6: 6) + 10 utility unit tests Architecture notes: - M2.5 schema validates via M2.3 tables - M2.6 uses M2.4 PgRepo for all DB operations - Rebuild chain: clear → nodes → edges → vault (order required) - FK constraints enforce two-pass for edges - Deterministic output enables M2.8 gate (byte-identical verification)
