Aska	8603839711	feat(ai-core): trace instrumentation, LLM thinker, decay scheduler ... - orchestrator: Tracer interface with spans for intent analysis, persona, subsession dispatch, context build, LLM streaming and each tool call; traces finish when the stream completes — the admin Trace waterfall finally receives data - background: Thinker generates real LLM thoughts (post-chat + silence triggers, recent history as context, empty/overlong outputs discarded); thoughts broadcast to web clients as 'thinking' WS messages; pipeline postChatHook triggers post-chat thinking after each round - memory: ApplyDecayAll + ListUserIDs with a 6h decay/purge cron in main (was implemented but never scheduled)	2026-08-20 20:57:27 +08:00
Aska	8495a4b055	feat(memory): hybrid vector search via embedder ... - repository: optional pgvector embedding column (migration with CREATE EXTENSION guarded by main), SearchByVector cosine search, vector-enabled insert path - service: SetEmbedder — memories are embedded on Add; Search merges vector hits with n-gram keyword matches (vector first, deduped) - embedder was already implemented (OpenAI-compatible API + n-gram FNV fallback) but never instantiated; main now wires it from EMBEDDING_API_URL/EMBEDDING_MODEL config	2026-08-20 20:57:13 +08:00
Aska	886fcf2216	fix(memory): rewrite dedup with n-gram keyword overlap + embedder ... - Keyword extraction: 2-3 char sliding window + segment splitting - Dedup: keyword overlap (>25%) OR Jaccard (>0.4) triggers merge - SearchByNGrams: pgvector GIN index on keywords array - Embedder: n-gram FNV hash (zero dep), OpenAI API with auto-fallback - GIN index on keywords column for fast overlap search - All tests pass	2026-08-12 18:24:04 +08:00
Aska	81ebdb910c	feat(memory): complete memory service with passing tests ... - model: Memory struct with categories/decay/keywords - repository: PG CRUD + keyword search + table migration SQL - service: dedup (Jaccard), keyword extraction, decay formula - 7 tests (3 DB integration + 4 unit), 96 total, vet clean	2026-08-09 20:51:01 +08:00
Aska	7295556c59	feat(services): add memory service — model, repository, service layer ... - services/memory/model: Memory struct with categories and decay - services/memory/repository: PostgreSQL CRUD + keyword search - services/memory/service: dedup, decay, keyword extraction - tests coming in follow-up commit	2026-08-09 20:50:01 +08:00
