v1.0.43 - Clockwork

[v1.0.43] Clockwork - 2026-04-24

Special thanks to @linuxdynasty for submitting a bunch of fixes and optimizations!

Added

• Runtime retention and privacy control plane:

  • added runtime retention sweep management in the database layer, including sweep budgeting, excluded-label handling, record collection, and immediate sweep triggering.
  • added admin retention endpoints for policies, legal holds, erasure requests, manual sweeps, and retention status.
  • added GDPR integration hooks so privacy and retention workflows can share the same server-side control surface.

• Retention administration UI:

  • added a dedicated Retention Admin page in the web UI with policy editing, legal hold management, erasure request processing, defaults loading, and sweep controls.
  • wired new client API types and routes so operators can manage retention behavior from the browser instead of only through raw admin calls.

• Constraint and planner regression coverage:

  • added extensive deterministic tests for constraint contract parsing, schema validation, Bolt database-manager behavior, transaction wrapper reuse, UNWIND merge batches, and fabric helper types.
  • added regression coverage around database-scoped rollback handling and deterministic multidatabase enforcement behavior.

• Knowledge-layer documentation and research material:

  • added a full knowledge-layer persistence implementation plan, expanded design material, Kalman-focused planning docs, and a new research-paper draft on persistence semantics. (v1.1.0)

Changed

• Retention configuration and operator surface:

  • expanded runtime config, example YAML, and macOS/app UI surfaces for retention and memory-management controls.
  • made chunk overlap configurable in the macOS app and web UI chunking flow.

• Cypher MERGE and UNWIND MATCH routing:

  • routed more UNWIND + MATCH/map-merge shapes through the hot path and tightened optional-match fallback behavior.
  • started using unique-constraint and unique-index information more aggressively for merge lookup and validation paths.

• Constraint contract parsing and validation internals:

  • replaced older regex-heavy constraint-contract parsing with allocation-free keyword scanning helpers.
  • normalized unique-constraint cache keys and extended contract matching to cover broader label combinations and namespace cases.

• Documentation and release content:

  • refreshed README, operations docs, compliance docs, user-guide indexes, and the hot-path cookbook to match the current runtime behavior.
  • removed or folded obsolete planning material into the newer knowledge-layer and compliance documentation set.

• Dependency maintenance:

  • refreshed Go module dependencies and updated UI package dependencies as part of the release range.

Fixed

• Database-scoped Bolt rollback correctness:

  • fixed Bolt explicit transaction rollback so rollback is honored against the correct selected database instead of leaking across database scope boundaries.
  • hardened transaction wrapper reuse paths and related rollback regressions in Bolt/Cypher integration tests.

• Constraint validation correctness and safety:

  • fixed unique lookup and validation paths to guard non-comparable values and avoid incorrect equality handling during unique checks.
  • corrected constraint-validation plumbing so unique indexes and schema checks stay aligned across storage and Cypher surfaces.

• Local LLM generation stability:

  • fixed CGO generation-path issues in the local llama integration, including causal-attention setup and health checks for non-unified KV caches.

• Deterministic multidatabase enforcement tests:

  • fixed rate-limit and enforcement test behavior to avoid timing-driven flakes and keep multidatabase coverage deterministic.

Tests

• Added and expanded coverage for:
  • retention manager behavior, retention admin handlers, and privacy/erasure workflows
  • Bolt database-manager integration, database-scoped rollback, and transaction-wrapper reuse
  • UNWIND/MATCH/MERGE hot-path routing and fallback behavior
  • constraint contract parsing, validation, schema interactions, and unique lookup edge cases
  • fabric helper coverage, plan-cache behavior, and multidatabase enforcement determinism

Documentation

• Added and refreshed:
  • GDPR compliance guidance and retention-policy operator documentation
  • knowledge-layer persistence plan and implementation details
  • Kalman behavioral signal planning notes
  • persistence-semantics research paper draft, evaluation plan, bibliography, and related-work notes
