v2.0.0 — Active Intelligence

[2.0.0] — Active Intelligence

Major release: Alaz graduates from a passive knowledge store to an active collaborator that observes, learns, and proactively surfaces the right context.

Added

• CLAUDE.md generator — alaz generate-claude-md emits a project-specific guide synthesized from the knowledge base; auto-refreshes on session start when stale (>24h).
• Smart PostToolUse hook — triggers on errors and file events with selective FTS; minimises noise while maximising signal.
• Dual LLM backend — Ollama native API (think:false fast path) with OpenAI-compatible fallback. Run fully local, fully remote, or mix and match.
• Git integration — post-commit hook ingests diffs; new MCP tools alaz_git_hot_files, alaz_git_coupled_files, alaz_git_timeline.
• v2 MCP surface — 76 tools total. New capabilities:
  • Alerts (alaz_create_alert, alaz_list_alerts, alaz_alert_history, alaz_delete_alert)
  • Error groups (alaz_error_groups, alaz_error_group_detail, alaz_resolve_error)
  • Logs (alaz_logs_query, alaz_logs_stats)
  • Work units (alaz_create_work_unit, alaz_list_work_units, alaz_update_work_unit, alaz_link_session_work_unit)
  • Project health (alaz_project_health), impact analysis (alaz_impact)
  • Advanced retrieval (alaz_rag_fusion, alaz_agentic_search)
  • Analytics (alaz_learning_analytics, alaz_search_analytics, alaz_record_usage)
• Spaced repetition — Migration 016 adds sr_interval_days, sr_easiness, sr_next_review, sr_repetitions to knowledge_items (SM-2 style).
• Learning analytics — Migration 018 exposes pipeline health and extraction outcomes.
• Related files extraction — learning pipeline now captures co-changed files per episode.
• Implicit click tracking — signal-weight learning consumes real usage, no manual feedback required.

Changed

• Lower cross-project promotion thresholds — patterns cross over to other projects faster.
• Hard-delete superseded items after a 7-day grace period instead of indefinite retention.
• Tighter extraction limits + minimum quality gates for higher-signal outputs.
• ColBERT & MCP refactor — MCP module split from a 1455-line monolith into per-domain handler sub-modules.
• FTS tokenization — OR-keyword expansion in PostToolUse hook for broader recall.
• LLM client — flexible JSON deserialization, reflection foreign-key guard.

Fixed

• Project name → ID resolution before repo queries.
• PostgreSQL AVG() NUMERIC cast to float8 for sqlx f64 compatibility.
• 21+ individual issues and 5 architectural improvements across the codebase.

Removed

• Internal deploy-specific references and migration artifacts from public history.
