asepharyana 185d81f0e0 feat(ai-moderation): reset offensive nickname instead of deleting message
When the ONLY violation is offensive_username (message content clean):
- Message is NOT deleted (nickname-only violation bypasses auto-delete)
- Member's server nickname is reset to default username via
  setNickname(null) (Discord shows the global username again)
- Action 'reset_nickname' logged to moderation_actions; cooldown
  10min per guild:user (LRU) so repeated messages by same member
  don't hammer the Discord PATCH
- Config: AUTO_NICKNAME_RESET_ENABLED / AUTO_NICKNAME_RESET_COOLDOWN_MS

asepharyana 4049ab4201 feat(ai-moderation): rich context + link media vision analysis
- Conversation context recency gates (GAP_MS/MAX_AGE_MS): drop stale
  messages before silence gaps; cold_start anchor + flow descriptor
  tells LLM whether conversation is ongoing or restarted
- [location] block: channel name, thread name, nsfw/age flags from
  captured metadata (thread names instead of bare IDs)
- Link media -> multimodal: text-batch URL fetches that resolve to
  images now run vision analysis (bounded 15s) and switch prompt to
  mixed mode; <web_content> gains og:title for page context
- pnpm-workspace.yaml: approve sharp build script (unblocks install)

Developer 6df4f306dd refactor: remove unused text analysis module and integrate Qdrant enhancements
Build & Deploy (Nix) / build-and-deploy (backend) (push) Successful in 2m30s
Build & Deploy (Nix) / build-and-deploy (discord-gateway) (push) Successful in 3m7s
Build & Deploy (Nix) / build-and-deploy (proxy) (push) Successful in 3m20s
- Deleted the text analysis prompt constants and helpers as they are no longer needed.
- Added batch search functionality for Qdrant to optimize vector searches.
- Implemented methods for deleting expired Qdrant points and invalidating cache based on content hash.
- Updated text batch processor to use new timeout configurations and modified content building for moderation prompts.
- Enhanced text cache store to support new Qdrant integration and improved cache invalidation logic.
- Introduced a new user reputation model with a more nuanced trust scoring system, including penalties and rewards for user behavior.
- Added unit tests for the new trust model to ensure correctness of penalty and trust gain calculations.
- Updated configuration schema to reflect new timeout settings and removed deprecated OpenAI moderation keys.

Developer fc475dfbb7 feat(automod): store semantic cache embeddings in Qdrant
Build & Deploy (Nix) / build-and-deploy (backend) (push) Successful in 3m7s
Build & Deploy (Nix) / build-and-deploy (discord-gateway) (push) Successful in 2m21s
Build & Deploy (Nix) / build-and-deploy (proxy) (push) Successful in 2m33s
New qdrantClient.ts (zero-dep fetch REST): ensure collection with cosine
distance (auto-recreate on vector-size change), upsert point w/ verdict
payload, search w/ expires_at filter + score threshold.

textCacheStore: when QDRANT_URL set, embeddings are upserted to Qdrant
(primary) and searched there first; Postgres embedding column remains as
legacy fallback for pre-Qdrant rows. Config: QDRANT_URL/COLLECTION/API_KEY.
QDRANT_URL already in repo .env; added to VPS env + GATEWAY_ENV secret.

Developer 1249ae81d8 perf(automod): compress prompts ~40% + semantic cache via AI_LLM_EMBEDDING_MODEL
Build & Deploy (Nix) / build-and-deploy (backend) (push) Successful in 3m4s
Build & Deploy (Nix) / build-and-deploy (discord-gateway) (push) Successful in 2m29s
Build & Deploy (Nix) / build-and-deploy (proxy) (push) Successful in 2m33s
Prompt overhaul (token-frugal, same quality):
- rules.ts 28KB -> 10.3KB: every normative rule kept (safe lists, SARA
  6 kategori, LGBT/Israel zero tolerance, anti-evasion, decision tree,
  evasi hierarchy, image rules) with duplicated phrasing removed
- examples.ts 24.7KB -> 20KB: all 31 teaching examples kept; analysis
  strings shortened, redundant categories/policy_version dropped from
  example outputs (both optional in the response schema)
- output.ts 13.8KB -> 6.8KB: compressed schema + personality + format
  rules; CRITICAL bans on generic analysis and reply-context requirement
  retained
- system.ts: MEDIA_INSTRUCTIONS compressed, key rules kept

Semantic moderation cache (AI_LLM_EMBEDDING_MODEL):
- New embeddingClient.ts: OpenAI-compatible embeddings + cosine
  similarity; degrades gracefully when model/key unset
- textCacheStore: stores embedding JSON per verdict, findSimilarTextModeration
  reuses near-duplicate verdicts (min 0.97 cosine, processing locks skipped)
- moderationOrchestrator: after exact-hash miss, embed text-only targets
  and reuse stored verdict for near-duplicates -> skips expensive chat
  completion for spam variants; fresh verdicts written back with embedding
- Config: AI_LLM_EMBEDDING_MODEL / MIN_SIMILARITY (0.97) / MAX_CANDIDATES (30)
- Migration 0012: ADD COLUMN embedding to text_analysis_cache (idempotent)
- .env.example documents the new vars

Developer dcd13482c2 refactor: break monorepo into 3 standalone services (gateway, backend, frontend)
Build & Deploy / build-and-push (backend) (push) Failing after 35s
Build & Deploy / build-and-push (discord-gateway) (push) Failing after 25s
Build & Deploy / build-and-push (proxy) (push) Failing after 25s
- Remove pnpm workspace, moon repo, and all monorepo tooling
- Delete packages/shared/, embed shared code directly into each service
- Copy packages/shared/src/* -> services/backend/src/shared/ and services/discord-gateway/src/shared/
- Replace all @bete/shared imports with @/shared/ path alias
- Remove @bete/shared workspace dependency from both services
- Update root package.json scripts from --filter to --prefix
- Rewrite Dockerfiles to build each service standalone
- Clean up biome.json, .gitignore, remove root drizzle.config.ts
