v0.3.0 — Phase-WIKI-FIX + Phase-TOOL + Step 1.LAT closure Three back-to-back milestones (174 commits since v0.2.0) restructuring Aura's substrate retrieval, agent loop latency, and tool surface. - Hard MaxIterations cap + step X/N pacing hint (US-LAT-01) - Single-shot prompt bias in agent overlays (US-LAT-02) - `text_response` as terminal tool — answer-as-argument (US-LAT-03) - Full EN restructure of agent overlays + MaxIterations cap to 20 (US-LAT-04) - Unified `search` tool — collapse 4 lookup tools into 1 (US-LAT-05) - Stream-time parallel tool dispatch (US-LAT-06) - Provider prompt caching for static prefix (US-LAT-07) - Inline wiki TOC in system prompt — nanobot MEMORY pattern (US-LAT-08) Direct retrieval bench 2026-05-22 surfaced 10 substrate bugs. After fix: FTS hit rate 0/20 → 20/20, score discrimination restored, p95 ≤75ms. - FTS5 mirror auto-sync on wiki write/delete (US-WIKI-FIX-01) - Embed cache key includes output_dim (US-WIKI-FIX-02) - Rebuild skip-and-continue on per-page embed error (US-WIKI-FIX-03) - Admin `/api/wiki/reindex` + boot dim-mismatch auto-detect (US-WIKI-FIX-04) - Filter system-category pages from default search (US-WIKI-FIX-05) - Dedupe wiki search results by slug (US-WIKI-FIX-06) - settings.updated_at default to CURRENT_TIMESTAMP (US-WIKI-FIX-07) - Embed n_ctx per-slot math + boot smoke (US-WIKI-FIX-08) Killed the tool RAG entirely per user mandate "togli il rag dei tool è una cagata; alla fine basta il search tool come hai te". Removed ~4000 LOC of dead/duplicated/over-engineered tool infrastructure. - KILL tool RAG entirely — all tools always-on in manifest (US-TOOL-01) - Delete 18 unregistered orphan Tool types — ~1500 LOC dead (US-TOOL-02) - Wire text_response + drop search_memory zombie (US-TOOL-03) - Description audit — EN-only + 200char cap + structural markers (US-TOOL-04) - Collapse schedule_task/list/cancel → `task(mode=)` (US-TOOL-05) - Collapse create_xlsx/docx/pdf → `create_document(format=)` (US-TOOL-06) - Align defaults with unified tool surfaces (US-TOOL-07) - MCP description override sidecar — `tools-overrides.json` (US-TOOL-08) - MCP supervisor — list_changed + circuit breaker + reconnect (US-TOOL-09) - Dim-mismatch auto-detect + rebuild for compact collection (US-TOOL-10) - ~-4500 LOC net (cleanup) vs ~+1700 LOC new substrate - 22 → ~15 tools in catalog after kitchen-sink collapses - 0 unused symbols, 6 TODO total in production code - `aura_tool_search_v2` Qdrant collection deleted (no longer needed) - All Anthropic / OpenAI-compat LLM endpoints gain `prompt_cache_key` support - `EMBEDDING_OUTPUT_DIM` setting now persisted in SQLite; restart on change triggers automatic Qdrant collection rebuild - `search_memory` tool removed (use unified `search` from US-LAT-05) - `tool_search` tool removed (manifest is always full) - `aura_tool_search_v2` Qdrant collection no longer created at boot - MCP supervisor adds per-server circuit breaker — flapping MCP servers will be auto-isolated after 3 consecutive failures
