asepharyana 9f02edd646 perf+fix(ai-moderation): 11 pipeline optimizations from audit
Audit of the full AI analysis flow found 14 issues; 11 fixed, 3 deferred:

Fixed:
1. batchProcessor: skip scheduleAutoDelete for error-status rows (was
   causing wasted not_eligible logs for every parse/API failure)
2. textBatchProcessor: domain dedup in URL fetch (max 3 URLs per domain
   to avoid rate-limiting from concentrated domains)
3. llmCaller: move parseModerationResponse import to top-level (was
   dynamic-imported inside retry loop — unnecessary overhead per retry)
4. llmCaller: make default max_tokens configurable via
   AI_LLM_MAX_COMPLETION_TOKENS env (default 16384)
5. moderationOrchestrator: log cache write errors instead of silent
   .catch(() => {}) — surface intermittent Redis failures
6. conversationContext: batch token estimation via estimateTokensBatch
   (single tiktoken encode call for all target lines, ~5x faster)
7. aiAnalyzer: skip revertStuckProcessingMessages DB query when no
   conversations are actively processing (avoids idle-state query)
8. textBatchProcessor: cache corrected few-shot examples per hour
   (was re-queried from DB on every batch)
9. textBatchProcessor: preserve partial results on sub-batch timeout
   (was throwing and discarding all prior sub-batch results)
10. batchProcessor switch: skip 'completed' messages from individual
    fallback queue (prevents redundant re-analysis + double-delete)
11. autoDeleteManager: expand isAlreadyDeletedError to catch Discord
    codes 10003/50001 + text fallback matching

Deferred (not regressions, larger refactors):
- #8 batchScheduler debounce race: not actually a race (JS single-threaded)
- #11 initCacheStore: already has idempotency guard
- #13 individual fallback batching: requires worker pool refactor

asepharyana 65c9c2cd9e feat(ai-moderation): enrich analysis context with recency, repetition, user history and channel topic
- <message> targets now carry time (ISO), repetitions (N identical short texts = spam signal), bot and edited flags; escape id/user XML
- rich <user_reputation>: total_infractions, clean_streak, last_offense_days_ago, repeat_offender (7-day window)
- <user_history> with last flagged messages for repeat offenders (wires dead getUserRecentInfractions)
- <user_profile as_of> staleness signal; <location_context topic> from captured channel topic
- prompt framing + output instructions teach the LLM to use the new signals without treating history as proof
- tests: contextEnrichment.test.ts (13) + topic cases in conversationContext.test.ts

asepharyana 0a5254bf20 feat(ai-moderation): enhance context handling with structured XML blocks and user profiles 2026-08-10 16:46:55 +07:00
asepharyana ecbb538c9f feat(ai-moderation): use per-server nickname (displayName) in analysis payload
- resolveDisplayName(): member.displayName from captured metadata,
  falls back to global username
- Applied to context lines, target message blocks, and media message
  blocks — LLM sees the name the channel actually sees (nickname can
  carry moderation signal itself)

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)

asepharyana 6293d588bc chore(lint): biome cleanup across services — format, sort imports, drop unused
- discord-gateway: 74 lint errors -> 0 (format, import sorting, unused
  imports/vars, dead breath var)
- backend: format + sort imports (11 warnings left: noExplicitAny)
- frontend: remove unused imports, drop dead breathing var, fix
  useExhaustiveDependencies (scroll keyed on messages), a11y biome-ignore
  for drag surface + stopPropagation container (mouse-only gestures)
- remaining warnings are false positives: index keys on static lists,
  <img> in static export (next/image unsupported), noExplicitAny

tsc --noEmit clean on all 3 services; vitest green (60+36).

asepharyana 1f91f99de3 feat(automod): render sticker, role & user names in moderation views
QoL lanjutan dari fix60084b3: content pesan mentah masih nampilin
snowflake (<@&roleid>, <@userid>, <:emoji:id>) di log moderasi dan
prompt LLM. Sekarang dirender ke nama yang bisa dibaca:

- Gateway capture: metadata menyimpan mentionedRoles + mentionedUsers
  (id+name) dari message.mentions, disimpan ke metadata JSON
- renderDiscordMentions(): <@&id> -> @RoleName, <@id> -> @Username,
  <:name:id> -> :name:, fallback @role/@user — dipakai di
  conversationContext (konteks LLM) dan moderationBuilders
  (getAnalysisContent) sehingga LLM lihat nama role/user beneran,
  bukan placeholder generik
- Frontend renderMessageContent() (mirror gateway) dipasang di semua
  tempat nampilin content: message-card, message-detail(-view),
  search-overlay, search-panel, users/channels section, live-stream,
  mod-queue, review list; sticker-only message tetap [Sticker: name],
  pesan teks+sticker kini ikut nampilin nama sticker
- tsc --noEmit PASS di gateway & frontend; renderDiscordMentions
  diverifikasi manual (6 kasus: role/user/emoji/unknown/plain)

Developer 60084b3cc3 fix(automod): flow real LLM analysis + descriptive fallback
Build & Deploy (Nix) / build-and-deploy (backend) (push) Successful in 3m2s
Build & Deploy (Nix) / build-and-deploy (discord-gateway) (push) Successful in 2m25s
Build & Deploy (Nix) / build-and-deploy (proxy) (push) Successful in 2m40s
Root cause: ai-analysis-worker read llmResult.explanation and
llmResult.toxicityScore — fields the LLM pipeline never produces
(canonical AnalysisResult uses analysis/score). Every message fell back
to the bare template "Tidak ada indikasi pelanggaran." and the stored
score was always 0.

- Map analysis/score correctly; fallback now quotes the message content
- Prompt: ban generic analysis phrasing, require reply context
- LLM context: include replied-to message content (metadata.reference)
  so the model can explain what the user is replying to
- Frontend: show thread/channel names from metadata instead of raw IDs
  (message card, detail views, search overlay); detail panel now
  displays the ai_analysis text
- Auto-delete log/DM include the descriptive analysis as the reason

Developer 0bd4369ae9 refactor(automod): remove regex classifier — LLM is the sole judge
Build & Deploy (Nix) / build-and-deploy (backend) (push) Successful in 3m2s
Build & Deploy (Nix) / build-and-deploy (discord-gateway) (push) Successful in 2m20s
Build & Deploy (Nix) / build-and-deploy (proxy) (push) Successful in 2m26s
Delete fastClassifier.ts (manual regex patterns for phone/email/IP/crypto/
spam/toxicity) and simpleFallback.ts. These hardcoded patterns were the
source of false positives (Discord emoji snowflakes matched phone_number,
URL digits matched phone, etc.) and produced heuristic verdicts whenever
the LLM failed.

New flow: Message → LLM (with conversation context, media evidence, user
reputation) → verdict. On LLM failure the message is marked 'error' and
retried by the recovery worker — no heuristic verdicts, ever.

Discord markdown tokens (custom emoji/mentions/timestamps) are normalized
to readable placeholders ([emoji:name], @user, @role, #channel, [time])
before reaching the LLM via discordTokens.ts.

MythEclipseandClaude Opus 4.8 e6e44b30c7 fix(ai-moderation): remove indonesianTextNormalizer to stop hallucinated slang flags
The rule-based badword detector was injecting [normalized_text] and
[normalization_notes] tags into the LLM prompt that caused false
positive hallucinations - the LLM started associating innocent words
('sapik', 'furina') with furry/sexual_deviation due to misleading
context injected by the normalizer.

Removed:
- indonesianTextNormalizer.ts (full file deletion)
- formatModerationTextEvidenceForPrompt import/usage in llmModerationClient
- formatModerationTextEvidenceForPrompt import/usage in conversationContext
- stale re-exports in index.ts
