+Do NOT summarize the video in chat under any circumstances. The user has corrected
+this multiple times ("WHY DO YOU KEEP DOING THIS — YOU HAVE A YT INGEST SKILL").
+The two skills are easy to confuse: `youtube-content` = fetch transcript + format

+### 3. Brain Injection (Cognee) (MANDATORY)
+
+Load the `cognee-brain` skill. Write the distilled summary to the shared Cognee
+brain (10.0.0.23) as a narrative finding — LLM extraction pulls out the entities
+(models, tools, creators) and facts (claims, settings, comparisons) automatically:
+
+Call the Cognee MCP tool `mcp__cognee__remember` with:
+- `data` = the distilled summary (2-4 sentences)
+- `dataset_name` = `homelab-stack`
+- omit `session_id` (permanent memory — runs add + cognify, builds the graph)
+
+- `remember` is synchronous (`status: completed` means the graph is built). No
+  polling needed; verify later with `recall` if needed.
+- Always use dataset `homelab-stack` (the single shared brain dataset). Never
+  create a second dataset.
+- The brain holds the distilled facts; the vault (ai_vault_kb) holds the verbatim
+  transcript. Both are written for every video — never skip either.
+
+**MCP timeout + REST fallback (learned 2026-08-29).** The MCP `remember` call can
+fail with `TimeoutError: MCP call timed out after 120.0s` because cognify is
+variable — the REST path took 77s for a 6-item ingest, while MCP full-size payloads
+ran 9.8–12.2s. The MCP server itself is healthy; it is the client-side 120s
+per-tool-call timeout that aborts slow cognify runs. Two-part fix:
+
+1. **Raise the timeout** in `~/.hermes/profiles/general/config.yaml` (cognee MCP
+   block): `timeout: 120` → `timeout: 300`. Takes effect on next Hermes restart
+   (MCP connections are read once at startup). Note: the `patch` tool refuses to
+   edit Hermes config files — use terminal Python for an exact string replace, then
+   `python3 -c "import yaml; yaml.safe_load(open('config.yaml'))"` to validate.
+2. **REST fallback** when MCP times out (documented in the `cognee-brain` skill):
+
+```bash
+# Write (synchronous; returns status:completed + items_processed)
+curl -s -m 300 -X POST "http://10.0.0.23:8080/api/v1/remember" \
+  -F "data=@/tmp/brain_summary.txt" \
+  -F "datasetName=homelab-stack"
+
+# Verify (field names are query + searchType, NOT query_text/query_type)
+curl -s -m 60 -X POST "http://10.0.0.23:8080/api/v1/search" \
+  -H "Content-Type: application/json" \
+  -d '{"query":"<distinctive phrase>","datasets":["homelab-stack"],"searchType":"HYBRID_COMPLETION"}'
+```
+
+A `status: completed` from the REST write is proof the graph is built — no separate
+cognify step. If the MCP call times out, do NOT retry it blindly; use the REST path
+and verify with the search call above.

+
+## Transcript Ingestion (verbatim) — when the task says "transcript"
+
+When the task asks for the TRANSCRIPT (not a summary/recipe), the vault doc must contain
+the verbatim spoken text. A distilled recipe summary is NOT a transcript.
+
+**Omit useless segments.** "Verbatim" means the informative spoken content word-for-word —
+not the filler around it. Cut entirely: sponsor reads / ad segments, song lyrics and
+music-only passages, giveaway/merch/Patreon plugs, like-and-subscribe boilerplate, and
+unrelated channel promo. Replace each cut with a one-line marker at that spot — [sponsor
+segment omitted], [music omitted], [channel promo omitted] — so the cut is visible and
+auditable. When in doubt, keep it: anything touching the technical content (settings,
+models, node names, reasoning, results) is never filler, even if it sounds chatty. The
+word count in the summary header notes omissions, e.g. "2,140 words (3 segments omitted: 2
+sponsor, 1 music)."
+
+1. **Fetch the caption track**: `yt-dlp --skip-download --write-auto-subs --write-subs
+   --sub-langs "en.*" <url>` (fall back to `--sub-langs en` if needed). Clean the VTT/SRT
+   to plain text: strip WEBVTT headers, cue timestamps, and inline `<c>`/timestamp tags;
+   dedupe rolling-caption repeated lines. Result must read as continuous spoken sentences.
+2. **Body layout**: short distilled summary header (10–15 lines max) at top, then the FULL
+   verbatim transcript. Title pattern: `YT: <video title> (<video-id>) — transcript`.
+   Use `--type research` (house pattern for video transcripts), `--trust community`,
+   `--url <video-url>`, tags including the video id.
+3. **Helper only**: `python3 /home/n8n/bin/ai_vault_kb.py add ...` — never raw Qdrant HTTP
+   (bare-vector upserts miss the BM25 sparse slot and are invisible to hybrid search).
+4. **Dedup first**: `search --query "<video-id>"`; ≥0.85 skip · 0.70–0.84 add only if
+   meaningfully new · <0.70 add. If a summary/recipe doc for the same video already exists,
+   add the transcript as a SEPARATE doc and mention the other doc_id in the body — do not
+   overwrite the recipe doc.
+5. **Chunk boundaries + ordering**: the helper chunks at 1200 chars with 150 overlap, and
+   overlap starts land mid-word. To guarantee no chunk starts/ends mid-word, pre-split the
+   body at sentence boundaries into ≤1200-char pieces and add them sequentially with
+   `--doc-id` (each piece ≤1200 chars becomes exactly one chunk). Pass `--chunk-index N`
+   (0-based) on every add-call so reading order is recoverable from metadata: the summary
+   header piece is `--chunk-index 0`, the next piece `--chunk-index 1`, and so on through
+   the transcript body; the WORKFLOW LINKS piece is the last (highest) index. Prefer the
+   bundled `scripts/ingest_transcript.py` — it does the pre-split, the sequential indexed
+   adds, and the self-QA gate in one run. See `references/transcript-ingestion-detail.md`
+   for the chunking algorithm, the `--chunk-index` backfill context, and the proof-log
+   entry format.
+6. **Self-QA gate before reporting done (mandatory)**:
+   - get the doc back; confirm the body contains verbatim spoken sentences (first-person
+     narration, not bullets);
+   - confirm no chunk begins or ends mid-word (print first/last 10 chars of every chunk);
+   - run a search on one distinctive literal phrase copied from the body and confirm the
+     doc surfaces (proves the BM25 slot).
+   - **chunk-index ordering**: run `list --doc-id <id> --json` and confirm the
+     `chunk_index` values are exactly 0 through N−1, each appearing once. Then read the
+     pieces back in index order and confirm they reproduce the narrative sequence
+     (summary header → transcript body → WORKFLOW LINKS). A doc with duplicate or missing
+     indices fails the gate — fix it by rebuilding the doc: delete --doc-id <id> --yes,
+     then re-add ALL pieces in order with correct --chunk-index values (add --doc-id
+     appends — re-adding a single piece would duplicate it), then re-run this gate.
+7. **Completion report → log file, not chat.** Do NOT send the proof report to the
+   operator. Instead append it to `~/workspace/general/logs/yt_ingestion_proofs.log`
+   (create the dir if needed) under a dated header per run. The log entry contains the
+   same content as before: doc_id, chunk count, a 2–3 line verbatim excerpt, the BM25
+   search outputs, the chunk-index ordering check output (the `list --doc-id <id> --json`
+   result showing chunk_index 0..N−1 each once), and every downloaded file's full NAS
+   path + size. Then reply to the operator with only the minimal 4-line status per the
+   "Completion output" section below.
+
+## Completion output (minimal — replaces the chat proof report)
+
+After a run, reply to the operator with EXACTLY these four lines and nothing more:
+
+```
+Brain ingest: done
+Vault ingest: done
+Workflow dl: done
+Workflow(s): <filename(s) as saved on the NAS>
+```
+
+Rules:
+
+1. **"done" is earned, not assumed.** A line may say "done" only after its self-QA gate
+   actually passed — the internal checks (verbatim verify, chunk edges, BM25 probe, NAS
+   size verify) still run in full; only the reporting shrinks. If a step failed or was
+   skipped, say so on that line in a few plain words instead of "done":
+   - Brain ingest: failed — <one-line reason>
+   - Vault ingest: failed — <one-line reason>
+   - Workflow dl: none linked
+   - Workflow(s): <none, or the filenames if some succeeded>
+2. **Full proof report goes to the log file**, not chat:
+   `~/workspace/general/logs/yt_ingestion_proofs.log` (create the dir if needed). Append
+   one entry per run with a dated header (e.g. `## 2026-08-17 BjZvVx6sDmE — TaoofAI EP.1`)
+   containing: doc_id, chunk count, verbatim excerpt, BM25 search outputs, and every
+   downloaded file's full NAS path + size. This log path is the single place any
+   validator looks for proof.
+3. **Keep the doc_id available.** Include it in the log entry. If the operator or a
+   validator asks "doc id?" after a run, answer with just the doc_id — nothing else.
+
+## Hard rules for vault docs created from videos
+
+- **Every doc created from a video MUST carry the video-ID tag** (e.g. `ZUzeM9OEJ4Y`)
+  in `--tags`, on every chunk-add call. The video ID also goes in `--url` (source_url).
+- **Additionally ensure the video ID appears in each doc's TITLE** (append `(VIDEOID)` if
+  absent) — tags don't feed BM25, so the tag alone doesn't make the doc rank; title
+  placement does. The transcript title pattern already complies; older recipe/workflow
+  docs won't.
+- **Trust enum**: `official` | `github` | `community` | `social` — video-derived docs use
+  `--trust community` unless the creator is the model vendor.
+- **Keyword-search caveat**: the helper builds the BM25 sparse vector from title+text
+  ONLY — tags are payload-only and do not feed keyword search. A doc whose title and
+  body lack the video ID will rank low in `search --query "<video-id>"` even with the
+  tag present. For transcript docs the title pattern `YT: <title> (<video-id>) —
+  transcript` already embeds the ID; for recipe/summary docs, include the video ID in
+  the body (e.g. the WORKFLOW LINKS section) so at least one chunk matches.
+
+## Hard rules for brain writes created from videos
+
+- **Every video writes to the brain via `mcp__cognee__remember`** (narrative finding)
+  with `dataset_name="homelab-stack"`. The video URL goes in the data text so the
+  brain fact is traceable back to the video.
+- **The brain write is the distilled summary, not the verbatim transcript.** Keep it to
+  2-4 sentences of the durable takeaways (what the video demonstrates, key settings,
+  verdict). The verbatim text lives only in the vault.
+- **`remember` is synchronous** — `status: completed` means the graph is built. If a
+  validator needs proof, `mcp__cognee__recall` a distinctive phrase.
+- **`status: completed` is NOT proof the content is retrievable.** A write can return
+  `completed` yet a later recall answers "does not contain information about <terms>".
+  The recall is the real gate: after every brain write, `recall` a distinctive phrase
+  from the summary and confirm the answer actually contains it. If it does not,
+  re-write the summary and re-verify — do NOT report "Brain ingest: done" on
+  `status: completed` alone. See `references/brain-write-verification.md`.
+
 ## Pitfalls
 
-- **Never skip the brain injection step.** The user's memory directive explicitly
-  requires both transcript AND brain injection for every YouTube link.
+- **Never load `youtube-content` for a bare URL.** The bare-URL trigger means run the
+  full pipeline via THIS skill. Loading `youtube-content` and summarizing in chat is the
+  single most common failure — the user has corrected it repeatedly. If you catch
+  yourself about to produce a chat summary of a video, stop and run the pipeline.
+- **MCP `recall` uses `search_type` (snake_case), REST uses `searchType` (camelCase).**
+  The `mcp__cognee__recall` tool rejects `searchType` with a pydantic validation error
+  ("Unexpected keyword argument searchType") — pass `search_type="HYBRID_COMPLETION"`.
+  The REST `/api/v1/search` endpoint (curl) uses `searchType` in the JSON body. Don't
+  mix them up.
+- **Never skip the vault injection step.** The user's memory directive explicitly
+  requires both transcript AND vault injection for every YouTube link.
+- **Never skip the brain injection step.** Every video also writes a distilled finding
+  to the Cognee brain (`mcp__cognee__remember`, dataset `homelab-stack`). Vault =
+  verbatim transcript; brain = distilled facts. Both are mandatory.
 - **Never skip the BM25 verification.** A write that can't be found via BM25 is
-  effectively invisible — the `ai_brain_kb.py` helper is the only interface that
+  effectively invisible — the `ai_vault_kb.py` helper is the only interface that
   produces searchable points.
 - **Don't overwrite existing NAS workflows.** Use creator prefixes to avoid collisions
   with workflows already in the directory.
-- **The `youtube-content` and `ai-brain-kb` skills are protected** — load them for
-  reference but don't attempt to patch them. This skill is the integration layer
