INTENT_MAX_ANSWER_LENGTH was too tight (objection_expression 200 chars truncated
good responses). Bumped all limits ~25-50%. Also fixed followUp filter that silently
dropped content when model split answer across answer+followUp fields — now appends
followUp as continuation when answer ends mid-sentence.

P0: Enrich Chapter 10 with detailed policy facts (QMAS scoring, GEP A/B/C
conditions, FAQ quick answers) so Claude can answer common questions directly
without tool calls. Replace absolute rule "never answer from memory" with
3-tier system: Tier 1 (direct from Ch10), Tier 2 (search_knowledge), Tier 3
(invoke_policy_expert).
P1: Context injector now always returns a kb_coverage_hint block — when KB has
results it tells Claude to prefer KB over web_search; when KB has no results
it suggests considering web_search. Web_search tool description updated to
reference the hint.

Short follow-up answers like "计算机，信息技术" were being classified as
OFF_TOPIC (0.85) because the InputGate has no conversation context. Now the
gate only runs when there are no previous messages (first message in conversation).
Mid-conversation topic management is handled by the Coordinator prompt.

Add section 5.6 "隐性转化引导" with trust-first conversion philosophy:
- Free facts vs paid analysis boundary
- "Taste-then-sell" strategy with positive but vague hints
- Assessment suggestion limited to max once per conversation
- Natural urgency only when fact-supported
- Post-assessment → full service transition only when user asks
- Anti-annoyance red line: never make user feel pushed to pay
Recalibrate info exchange (4.3): warm acknowledgment without deep analysis.
Add value framing (4.4) and post-assessment guidance (4.5).

Update coordinator system prompt to enforce pricing rules:
- All assessments cost 99 RMB (one-time per user), no free assessments

- Replace "免费初步咨询" with tiered service model

Haiku sometimes returns JSON wrapped in ```json ... ``` code blocks,
causing JSON.parse to fail. Strip markdown fences before parsing.

injectIntoMessages() was JSON.stringify-ing array content (with image blocks),
turning base64 data into text tokens (~170K) instead of image tokens (~1,600).
Fix: append context as a new text block in the array, preserving image block format.
Also fixes token estimation to count images at ~1,600 tokens instead of base64 char length,
and adds debug logging for API call token composition.

80K was too aggressive and caused premature context loss. Now triggers
at 160K tokens with a target of 80K after compaction.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The auto-compaction logic (threshold 80K tokens, summarize older
messages via Haiku) existed but was never called in sendMessage flow.
Now called after context injection, before agent loop.

Historical images/PDFs were being re-downloaded and base64-encoded for
every API call, causing 200K+ token requests. Now only the current
message includes full attachment blocks; historical ones use text
placeholders like "[用户上传了图片: photo.png]".

Build preloads models to /root/.cache/huggingface (HF default).
Volume must mount there too, not a separate /models path.
Remove HF_HOME env override to keep paths consistent.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add docling_models volume mounted at /models in container
- Set HF_HOME=/models/huggingface at runtime (via docker-compose env)
- Models download once → persist in volume → survive container rebuilds
- Build-time preload uses || to not block build if network unavailable

DocumentConverter() constructor only sets up config, models are lazily

Add IBM Docling as a Python FastAPI microservice for high-quality document
parsing with table structure recognition (TableFormer ~94% accuracy) and
OCR support, replacing pdf-parse/mammoth as the primary text extractor.
Architecture:
- New docling-service (Python FastAPI, port 3007) in Docker network
- knowledge-service calls docling-service via HTTP POST multipart/form-data
- Graceful fallback: if Docling fails, falls back to pdf-parse/mammoth
- Text/Markdown files skip Docling (no benefit for plain text)
Changes:
- New: packages/services/docling-service/ (main.py, Dockerfile, requirements.txt)
- docker-compose.yml: add docling-service, wire DOCLING_SERVICE_URL to
knowledge-service, add missing FILE_SERVICE_URL to conversation-service
- text-extraction.service.ts: inject ConfigService, add extractViaDocling()
with automatic fallback to legacy extractors
- .env.example: add FILE_SERVICE_PORT/URL and DOCLING_SERVICE_PORT/URL
Inter-service communication map:
conversation-service → file-service (FILE_SERVICE_URL, attachments)
conversation-service → knowledge-service (KNOWLEDGE_SERVICE_URL, RAG)
knowledge-service → docling-service (DOCLING_SERVICE_URL, document parsing)

Claude API enforces a hard 5MB limit per image (not 20MB as previously
set). PDFs have a 32MB total request limit; set individual PDF cap to
25MB to leave room for prompt/messages. The downloadAsBase64 method now
accepts a per-type maxSize parameter.

MinIO presigned URLs use Docker-internal hostname (minio:9000), making
them inaccessible from both Claude API servers and user browsers.
Changes:
- file-service: add /files/:id/content and /files/:id/thumbnail proxy
endpoints that stream file data from MinIO
- file-service: toResponseDto now returns API proxy paths instead of
MinIO presigned URLs
- coordinator: buildAttachmentBlocks now downloads files via file-service
internal API (http://file-service:3006) and converts to base64 for
Claude API (images, PDFs) or embeds text content directly
- Configurable FILE_SERVICE_URL env var for service-to-service calls
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Claude API cannot fetch arbitrary URLs. Text-based attachments (txt, csv,
json, md) are now downloaded via their presigned MinIO URL and embedded
directly as text blocks. PDF uses Claude's native document block. Added
50KB size limit with truncation for large text files.
buildMessages() is now async to support text content fetching.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
1. Coordinator now sends all attachment types to Claude:
- Images → native image blocks (existing)
- PDF → native document blocks (Claude PDF support)
- Text files (txt, csv, json, md) → text blocks with filename
Extracted common buildAttachmentBlocks() helper.
2. File-service generates thumbnails on image upload:
- Uses sharp to resize to 400x400 max (inside fit, no upscale)
- Output as WebP at 80% quality for smaller file size
- Stored in MinIO under thumbnails/ prefix
- Generated for both direct upload and presigned URL confirm
- Non-blocking: thumbnail failure doesn't break upload

The model was putting internal notes like "引导回移民话题" in the followUp
field instead of actual user-facing questions. Two fixes:
1. Schema: describe followUp as "必须以？结尾，禁止填写内部策略备注"
2. agent-loop: only yield followUp if it contains ？or ? (question mark)

- findForEvolution() now excludes DELETED conversations (should not learn from deleted data)
- getConversation() rejects DELETED conversations for user-facing operations (sendMessage, getMessages, etc.)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The delete conversation endpoint was a no-op — it verified ownership but
never actually modified the record. Users saw conversations disappear
(frontend optimistic removal) but they reappeared on refresh.
Changes:
- conversation.entity.ts: Add DELETED status, softDelete() and isDeleted()
- conversation.service.ts: Call softDelete() + update instead of no-op
- conversation-postgres.repository.ts: Exclude DELETED conversations
from findByUserId() queries so they don't appear in user's list
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
AdminConversationController's GET /:id was intercepting requests to
AdminEvaluationRuleController (matching "evaluation-rules" as an id param).
Similarly, DELETE /:id was matching "cache" as an id.
Changes:
- conversation.module.ts: Register AdminMcpController and
AdminEvaluationRuleController before AdminConversationController
(more specific prefixes must come first in NestJS)
- admin-evaluation-rule.controller.ts: Move static routes (POST /test,
DELETE /cache) before dynamic routes (GET/:id, DELETE/:id)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The AdminEvaluationRuleController in ConversationModule needs the
EVALUATION_RULE_REPOSITORY token. Even though AgentsModule is @Global(),
Symbol-based providers must be explicitly exported to be available
in other modules.

The mapEventToStreamChunk was mapping both 'usage' (per-turn) and 'end'
(final) events to type 'end', causing the gateway to emit multiple
stream_end events. This made the frontend create a separate message
bubble (with its own bot avatar) for each agent loop turn.
