What's Changed

• Async hooks, fix N+1 cluster query, optimize SessionStart by @gvonness-apolitical in #107
• Release v0.5.1 by @gvonness-apolitical in #108

Full Changelog: v0.5.0...v0.5.1

v0.5.0

Fixed

• MCP config written to wrong file: causantic init was writing MCP server configuration to ~/.claude/settings.json, but Claude Code reads MCP servers from ~/.claude.json. MCP config now writes to ~/.claude.json; hooks remain in settings.json. Includes automatic migration of existing entries from settings.json to ~/.claude.json on re-init.
• Uninstall cleanup: causantic uninstall now removes MCP entries from both ~/.claude.json (current) and ~/.claude/settings.json (legacy).

Upgrade

Run npx causantic init to migrate your MCP config to the correct file. Existing installs will be migrated automatically.

v0.4.1

Added

Full Changelog: v0.4.0...v0.4.1

v0.4.0

Highlights

• Episodic chain walking: Redesigned recall/predict from graph traversal to chain walking. Seeds found by semantic search; the causal graph unfolds them into ordered narrative chains.
• Sequential edge structure: Replaced m×n all-pairs edges with sequential linked-list. All edges stored as single forward rows with uniform weight.
• 9 MCP tools: Added search (semantic discovery), hook-status, stats, and forget (with semantic deletion). Replaced explain with search.
• 14 skills: Added /causantic-forget, /causantic-status, /causantic-summary. Merged /causantic-context into /causantic-explain. Rewrote /causantic-crossref for cross-project search.
• Semantic deletion: forget tool supports topic-based deletion via query/threshold parameters with dry-run preview.
• Schema v8: Composite indices on edges for directional chain walking.
• Dashboard timeline: Horizontal swimlane timeline with chunk inspector and chain walk viewer.
• Chain quality benchmarks: Coverage, mean chain length, score per token, fallback rate.

Breaking Changes

• explain MCP tool removed (use recall or search)
• /causantic-context skill removed (use /causantic-explain)
• Sum-product traverser replaced by chain walker
• Hop-based decay removed; chain scoring uses direct cosine similarity
• Config sections removed: decay, traversal.minWeight, hybridSearch.graphWeight

See CHANGELOG.md for full details.

Full Changelog: v0.3.6...v0.4.0

v0.3.6

Fixed

• MCP error messages: Tool failure responses now include the actual error message instead of generic "Tool execution failed", making transient errors diagnosable without opt-in stderr logging.

Changed

• CI formatting enforcement: Added format:check step to CI workflow so formatting drift is caught before merge.
• Circular dependencies resolved: Extracted shared types into src/maintenance/types.ts and src/dashboard/client/src/lib/constants.ts to break 5 circular dependency cycles.

Housekeeping

• Fixed 5 ESLint warnings (consistent-type-imports, unused imports).
• Bumped typedoc 0.28.16 → 0.28.17 (fixes moderate ReDoS in markdown-it).
• Synced package-lock.json.
• Ran prettier on 19 files with formatting drift.
• Archived stale documentation for removed vector clock and decay systems.

What's Changed

• Housekeeping: lint, formatting, typedoc vuln, circular deps by @gvonness-apolitical in #85
• Archive stale docs for removed vector clock and decay systems by @gvonness-apolitical in #86
