Theme 4 · Local LLM deployment (Ollama / bge-reranker / RAGFlow)

This is the synthesis page for 本地大模型部署 — Robin's local inference and retrieval layer that serves the entire agent stack documented in /themes/03-ai-agents.md. The fleet combines an Ollama serve with multimodal + embedding models, an LM Studio instance running BAAI/bge-m3, a bge-reranker rerank service, and a RAGFlow KB layer; four adjacent NAS subsystems (NocoDB / SeaFile / Wiki.js / Feishu mail) sit alongside RAGFlow and share the same daily cron health-check pipeline.

What this theme covers

  • Local inference runtime: Ollama serve on the desktop (host 192.168.192.67, port 11434) running qwen2.5vl:7b for vision and nomic-embed-text / BAAI/bge-m3 for embeddings.
  • Local reranker: bge-reranker served on desktop port 8090.
  • Local embedder (LM Studio): BAAI/bge-m3 on port 7997 (LM Studio OpenAI-compatible API).
  • KB retrieval layer: RAGFlow (http://10.10.10.254:9980) — 18 KB / 32,709 docs / 116,254 chunks as of last sync 2026-08-03.
  • Adjacent NAS subsystems: NocoDB (http://10.10.10.254:8081), SeaFile (http://10.10.10.254:9898), Wiki.js (http://10.10.10.254:3000), Feishu mail (IMAP polling, awaiting Robin's IT password).

The diagram shows the three local inference services (Ollama serve, LM Studio, bge-reranker) feeding the RAGFlow KB layer, with the four NAS subsystems (NocoDB / SeaFile / Wiki.js / Feishu mail) attached at the metadata / file / published-deep-read / IMAP layer. All three inference services and all four subsystems are probed nightly by update-sources.sh at 02:30.

Service-down incident (2026-07-17 → ongoing)

This is the dominant operational fact for the theme right now.

  • Incident start: Desktop AI service on 192.168.192.67 stopped responding at 2026-07-17. Affected ports: 7997 (LM Studio embed), 8090 (bge-reranker), 11434 (Ollama serve). All three local inference endpoints are simultaneously offline. Documented in /sources/2026-07-27-4-27-sop-vs-implementation.md §4 (Ollama visual-review degradation).
  • Operational impact: LDR SOP Step 4 (Ollama visual review of extracted PDF figures) cannot run — Robin's literature-deep-read pipeline falls back to human-in-the-loop visual review of SeaFile-hosted figures. Cross-agent RAGFlow queries fall back to metadata-only (NocoDB tables, Wiki.js GraphQL, SeaFile file listing) since vector retrieval depends on the embedder and reranker.
  • Recovery procedure: documented at /sources/2026-07-27-4-27-sop-vs-implementation.md §4 — Robin to run ollama serve & and ollama pull qwen2.5vl:7b on the desktop, then verify with the ollama_vision smoke test in the same file.
  • Status note: This is a watchlist item, not a themes.md row, because the underlying root cause (desktop service restart) is operational not recurring. Tracked implicitly through the LDR SOP and the daily cron health probe — when RAGFlow's /api/v1/health returns 200 and /api/v1/datasets returns 401 (auth-only), the KB inventory is still readable; the dependency is on the embed/rerank services for retrieval quality.

RAGFlow KB inventory (18 KB / 32,709 docs / 116,254 chunks)

Snapshot from /sources/ragflow.md (last sync 2026-08-03T18:30:02Z, landing 200, /api/v1/health 404, /api/v1/datasets 401 — auth confirmed, retrieval path not exercised since the incident).

Embed-model distribution shows the migration story: earlier KBs (Organoid, 3Brain, Cellink, RAGFlow, Celvivo1, nanotemper, 废弃库) were embedded with nomic-embed-text@Ollama; later KBs (Organoid1, Organoid2, Celvivo, FemtoBiomed_electroporation, cellshot, LaminarWash, Celvivo commercial, Cellshot厂家, huibaibio, Organoid3) were embedded with BAAI/bge-m3@LM-Studio. The seer KB is the only one using a non-local embedder (text-embedding-v4@Tongyi-Qianwen). This is a real production fleet, not a single notebook.

RAGFlow 0.17 server-side cap (operational note)

/sources/ragflow-documents.md documents that RAGFlow 0.17 server-side caps /api/v1/documents to 30 docs per request and silently ignores the offset parameter. Coverage in the documents sample:

  • 6 small KBs (≤30 docs): 100% coverage
  • 12 large KBs (>30 docs): only first 30 sampled, no pagination possible from the API alone
  • Total sample: 401 doc-name rows across 18 KBs

Workaround for full enumeration: read the KB directly through Wiki.js, NocoDB metadata, or the RAGFlow doc PDF dump under SeaFile. Documented at /sources/ragflow-documents.md header.

Adjacent NAS subsystems (one-line summaries)

Each subsystem has its own source page; the bullets below are the cross-agent query affordances.

NocoDB — metadata store

  • Endpoint: http://10.10.10.254:8081 · 13 lit tables · 6,604 records (2026-07-27 snapshot; /sources/nocodb.md last-sync timestamp $(date -u +%Y-%m-%dT%H:%M:%SZ) is unrendered — the cron that wrote the source page left the template unfilled).
  • Per-table scale (last full census): brain_organoid_literature 103, intestinal_organoid_literature 9, Celvivo_literature 109, cardiac_organoid_literature 11, cancer_organoid_literature 129, liver_organoid_literature 28, other_organoid_literature 724, kidney_organoid_literature 23, retinal_organoid_literature 4, Cellink_literature 2,499 (largest), organoid_literature (old) 2,777, lung_organoid_literature 48, 3Brain_literature 147.
  • API quirk: Cellink library 已精读 SingleSelect options=[] (NocoDB bug) — cannot PATCH "是". Documented at /sources/2026-07-27-4-27-sop-vs-implementation.md §3. Workaround: write 精读摘要 + 精读日期 to PATCH-able fields; mark 已精读 = 是 via the wiki synthesis layer instead.
  • Cross-link: /sources/nocodb.md

SeaFile — large-file storage

  • Endpoint: http://10.10.10.254:9898/api2/ · public domain https://fb.biokingdom.top for share-links · 4 repos / 77 GB total.
  • API quirk: port 5000 is the Web UI reverse proxy, not the API. Token auth via Authorization: Token *** header. Share-link ?dl=1 suffix is required for direct download.
  • Daily use: LDR SOP Step 5 uploads PDF + 3 extracted figures → SeaFile → embeds ![]() markdown in Obsidian / Wiki.js / OpenWiki. Documented at /sources/ldr-report-template.md §4 and §5.
  • Cross-link: /sources/seafile.md

Wiki.js — published deep-read layer

  • Endpoint: http://10.10.10.254:3000/graphql · estimated ≥ 1,648 pages (based on max page id 1633) · zh/literature subpath is the primary publishing target.
  • API quirk: pages.list(limit:N) server-side caps to ~50 regardless of N; real count requires 5-orderBy union (TITLE / UPDATED / CREATED / ID / PATH) — documented at /sources/wikijs.md header. The "47" number from earlier 7-27 evidence is a server-side cap artifact, not the true count.
  • Daily use: LDR SOP Step 7 publishes deep-read reports to Wiki.js for cross-device / customer-facing reading. Maintenance is owned by wikijs-obsidian-sync skill (Robin + LDR auto-publish).
  • Cross-link: /sources/wikijs.md

Feishu mail — IMAP polling (awaiting credentials)

  • Endpoint: imap.feishu.cn:993 (CN) or imap.larksuite.com:993 (INTL) · LOGIN auth · 16-char app password required.
  • Status: script ~/.local/bin/openwiki-update-feishu-mail.sh is drafted (Robin 2026-07-29 spec); cron entry */30 * * * * is not yet in crontab. Page at /sources/feishu-mail.md is intentionally blank pending credentials.
  • Operational rule (Robin 7-28): Feishu mailbox is not the same as Gmail — openwiki auth google does not reach it. Feishu needs a separate IMAP credentials path through ~/.openwiki_env.sh.
  • Cross-link: /sources/feishu-mail.md

Daily operations

Two cron pipelines drive the local-LLM fleet:

    Cron3 -.future.-> OpenWiki
    RAGFlowP -.depends on.-> OllamaEmbed
    RAGFlowP -.depends on.-> LMStudioEmbed
    RAGFlowP -.depends on.-> RerankerSvc

The 02:00 cron pulls 3 connectors and runs M3 agent synthesis (writes to /themes/ and /commitments/). The 02:30 cron pulls counts from the 4 NAS subsystems. The 30-min Feishu cron is queued but inactive until IMAP creds land. After each cron, OpenWiki commits and pushes to the Gitea public mirror.

  • Health check: ~/.local/bin/openwiki-update-sources.sh probes each NAS subsystem's API; on success the source page is rewritten; on failure the previous good state remains.
  • Cross-agent query: Hermes / MiniMax code reads sources/{ragflow,nocodb,seafile,wikijs,feishu-mail}.md to discover "what's in this system" without an SQL/GraphQL round-trip; the 4 OpenWiki bridge skills route the cross-agent queries (see /themes/03-ai-agents.md §"MiniMax code").

Cross-cutting relationship

  • Consumed by /themes/03-ai-agents.md — every Hermes / MiniMax code / Codex call depends on the local LLM fleet (Ollama / bge-reranker / RAGFlow). The 2026-07-17 desktop service-down incident is the live dependency that breaks the cross-agent workflow.
  • Hosts the evidence layer for /themes/01-organoid-equipment.md, /themes/02-bioprinting.md, and /themes/05-robin-research.md — RAGFlow KBs (Celvivo / 3Brian / Cellink / Organoid1-3 / etc.) are the deep retrieval surface behind every vendor deep read; NocoDB is the metadata catalog; Wiki.js is the public publishing target.
  • Privacy rule (Robin 7-28): Feishu mailbox is not Gmail. The /sources/feishu-mail.md page exists precisely to prevent future agents from trying openwiki auth google against it. Permanent memory record.

Backlog for this theme

  • Bring desktop AI service back up — restart ollama serve + ollama pull qwen2.5vl:7b + LM Studio + bge-reranker on 192.168.192.67. Without this, the LDR SOP visual review step is degraded and RAGFlow vector retrieval is metadata-only.
  • Fix NocoDB /sources/nocodb.md unrendered timestamp — the page contains literal $(date -u +%Y-%m-%dT%H:%M:%SZ) in the header; needs the cron template to actually substitute the variable. Documented but not yet fixed at the source page level.
  • SeaFile source-page library-name template — /sources/seafile.md has 6 library rows with ? placeholders for ID / size / file count / last update; the upstream update-sources.sh is not filling them. Either fix the script or remove the table.
  • RAGFlow 废弃库 (15,922 docs / 1,604 chunks) cleanup question — Robin 7-27 said "永久不动". Currently the largest KB by doc count but only the 4th-largest by chunk count. Surface again only if Robin changes stance; do not auto-clean.
  • Wiki.js ≥ 1,648 page real count — server-side cap of ~50 in pages.list(limit:N) is a known RAGFlow 0.17-style artifact. Full enumeration requires either a Wiki.js DB-direct query or a frontend crawler. Documented as a known limitation in /sources/wikijs.md.
  • Feishu IMAP integration — script drafted; awaiting Robin IT to enable IMAP/SMTP and provide a 16-char app password. Once landed, crontab adds */30 * * * * entry and /sources/feishu-mail.md starts receiving real evidence rows.
