v1.0.26 Cypher Mutations

[v1.0.26] - 2026-03-20

Changed

• Cypher mutation pipeline compatibility:
  • generalized execution handling for complex mutation chains combining UNWIND, MERGE, SET, OPTIONAL MATCH, WITH, and WHERE
  • improved clause sequencing reliability for multi-stage write statements with intermediate projections.
• Proxy/base-path runtime behavior:
  • restored and hardened proxied UI/base-path asset loading behavior for containerized deployments
  • improved path normalization to reduce route/asset resolution drift behind reverse proxies.
• Managed vector/query execution safeguards:
  • tightened vector/search-related persistence and serialization guardrails for large payload handling
  • improved runtime safety defaults for high-volume decode/read paths.

Fixed

• Unique-key conflict handling in batched MERGE writes:
  • fixed batched UNWIND ... MERGE paths to correctly reuse matching nodes during a statement, preventing false duplicate-create violations under unique constraints.
• Mutation context propagation across chained clauses:
  • fixed variable binding continuity so downstream relationship merges resolve correctly after intermediate WITH projections and optional matches.
• Aggregate alias continuity across chained MATCH stages:
  • fixed alias preservation in chained query stages to prevent dropped/incorrect projected values.
• UI/path security hardening:
  • fixed reflected path handling in UI routing flows to mitigate injection/open-redirect risk surfaces.
• Storage path-safety hardening:
  • fixed segment/file access validation in WAL-related paths to reduce traversal-style file access risk.
• Dependency security updates:
  • upgraded vulnerable transport/runtime dependencies to patched versions in security-sensitive protocol paths.

Tests

• Added/expanded regression coverage for:
  • complex Cypher mutation shape permutations (UNWIND + chained MERGE/OPTIONAL MATCH/WITH/WHERE)
  • unique-constraint behavior under batched merge writes
  • UNWIND property substitution and merge-chain execution edge cases
  • proxy/base-path UI routing behavior
  • storage path validation and bounded message-pack decode limits.

Documentation

• Added/updated policy and project documentation for patent/licensing posture clarity, PATENTS.md
