Lecture-to-Notes

Turn a lecture recording (video or audio-only) into structured notes. Every heavy stage runs locally at 0 Claude tokens; Claude only does the final synthesis. This page is the map; detail lives in reference/, one topic per file.

File	What is in it
`reference/pipeline.md`	Per-stage flags, thresholds, JSON schemas, timeouts, observability
`reference/note-spec.md`	Note quality spec, tier scoring, width table, synthesis prompt requirements
`reference/segmented-mode.md`	Multi-talk workshop folders → per-segment L2/L3 + Hub + web viewer
`reference/multi-camera.md`	One long recording + many phone clips/photos → one timeline
`reference/decisions.md`	Post-mortems, benchmarks, wrong turns, VRAM measurements

HARD RULES

==ASK the user what language the speaker(s) used== (English / Mandarin / bilingual code-switching) before transcribing. There is no default and transcribe_video.py exits without --lang. A wrong guess makes Whisper hallucinate Chinese from accented English and the transcript is unusable.
==Never skip Stage D (VLM) or Stage E (grounding)== for speed or for a deadline. ==The user has not set a deadline; do not invent one.== If a stage really is too slow (>2 h ETA), report the ETA and ask.
==Never auto-correct the transcript.== Flag suspects, let synthesis resolve them. Both auto-correction passes ever built were measured and retired — see reference/decisions.md#asr-auto-correction. Do not add an auto-apply mode.
==Do not bypass the collapse auto-retry.== transcribe_video.py auto-runs retranscribe_segment.py --auto on detected token-collapse. If collapses survive that, escalate (wider beam + --no-repeat-ngram-size + a glossary), never skip.
==The VLM does not do OCR.== Stage D asks only for semantic signals. Text comes from Stage B quick_text, Stage B2 clean_text, or pdf_text.json. ocr.vlm_text is an always-empty compatibility field.
==Serialize all GPU work.== Whisper and the VLM may not run concurrently on an 8 GB card, and frame extraction must not run alongside transcription.
==On an 8 GB card, never exceed --batch-size 4 with --beam-size 10==, and never combine --beam-size 15 with sequential mode — that crashes (0xC0000005). The measured sweet spot is --batch-size 3 --beam-size 10.
==Director batch dispatch==: for a multi-lecture batch, dispatch Steps 1–9 as one subagent and Step 10 synthesis as a separate fresh subagent, spawned only after slides_grounded.json exists. A single subagent bounces during the long GPU waits and burns 30+ min of wall time per lecture.
==Order material by REAL CAPTURE TIME — never by filename, never by the printed agenda.== Filenames are labels, not clocks: a camcorder counter restarts across days (a two-day shoot has two 00000), a recorder's 240526_1119.mp3 sorts into the middle of the video files, and on-site -1-/-2- labels get stuck on the wrong file. Run scripts/batch/course_timeline.py BEFORE segmenting any multi-source course; manifest.json clip order and L1_coarse.md section order must both be built from it. An agenda is not a clock either — the 2024-05 Conference-Y conference ran ~25 min early on day 1 and ~35 min late on day 2, while its break gaps matched to the minute.
==🚫 PHI red line==: if the recording contains patient-identifiable content (case discussion, ward rounds, named patients), transcribe LOCAL ONLY — drop --engine groq. When unsure, ask; default to local.

Input types and routing

==Start here. route_inputs.py is the front door== — it classifies a folder and prints the ordered commands plus the questions a human must answer. It is plan-only: it never runs anything and never writes a file.

python <skill-dir>/scripts/route_inputs.py <material_dir> [--recursive] [--out-dir DIR] [--json]

What is in the folder	Slide source	Route
Video, no deck	frames from the video	Path A — Steps 5–7
Audio/video + PDF deck (==preferred==)	PDF text + page renders	Path B — `build_slides_from_pdf.py`
Audio/video + loose slide images (≥3)	the images themselves	Path B-images — `build_slides_from_images.py`
Audio only, no deck	none	Path C — transcript-only note
N-up handout PDF	cropped tiles	Path B-multi — `crop_multiup_pdf.py` first
Multi-talk workshop folder	per segment	`reference/segmented-mode.md`
One long recording + many phone clips/photos	per source	`reference/multi-camera.md`
`.pptx` / `.docx` / `.key`	—	convert to PDF yourself first; there is no conversion step here

==Multi-source contract==: when two or more independent sources are present, establish the timeline BEFORE anything else — course_timeline.py <course_dir> for a course folder with a manifest (it writes _seg/real_timeline.json, maps photos onto the recordings, and with --reorder-manifest fixes clip order at the root), or media_capture_index.py --emit-alignment alignment.json for a loose material folder. ==Capture timestamps are HYPOTHESES; transcript cross-correlation (xcorr_media_offsets.py) is EVIDENCE.== A source whose reliable flag is false got its start from mtime or has none — it must not be aligned on. Nothing is ever auto-corrected: a claimed-vs-measured disagreement >5 s is flagged "conflict": true for a human to judge. Details in reference/multi-camera.md.

Pipeline

One command plus its purpose per step; flags, thresholds and outputs are in reference/pipeline.md.

Step 1 — Ask the language (mandatory, no command)

English / Mandarin / bilingual? Accented speakers? Code-switching mid-sentence? Use AskUserQuestion if the user has not said. HARD RULE 1.

Step 2 — Set up the lecture directory

One directory per lecture holds every intermediate; name it {date}_{speaker}_{topic}, the shape finalize_to_vault.py parses.

Step 3 — GPU pre-flight

python <skill-dir>/scripts/gpu_check.py --out-dir "$OUT_DIR" --min-free-mb 6000

Gate before transcription and again before Stage D. Exit 0 proceed, 1 warn and proceed, 2 blocked — surface it, ==do not retry in a loop==. A card whose total VRAM is under the threshold (2–4 GB laptops) is GPU_TOO_SMALL, exit 0: not contention, nothing will free up — proceed with the CPU path (transcribe_video.py --device cpu --model small, or --engine groq). → reference/pipeline.md#gpu-check

Step 4 — Transcribe

python <skill-dir>/scripts/transcribe_video.py "<media>" \
    --output-dir "$OUT_DIR" --lang <zh|en|bilingual|auto> \
    --batch-size 3 --beam-size 10

Local faster-whisper by default; --engine groq is an optional offload (HARD RULE 9). Default model alias is breeze25 (needs a local model dir); on a machine without one, pass --model large-v3, which faster-whisper downloads. Recordings over ~30 min go through the chunked runner instead. → reference/pipeline.md#transcription

Step 5 — Stage A: frame extraction (Path A only)

python <skill-dir>/scripts/extract_slides.py "<video>" --output-dir "$OUT_DIR" --interval 15

Writes slides/frame_NNNN.jpg + slides/timestamps.json, phash-deduping adjacent near-identical frames. Path B/B-images skip this. → reference/pipeline.md#stage-a

Step 6 — Stage B: quick OCR + entropy (Path A only)

python <skill-dir>/scripts/quick_ocr.py "$OUT_DIR"

RapidOCR on every frame → slides_raw.json. ==Required==: without it every slide looks decorative to the Stage D gate. → reference/pipeline.md#stage-b

Step 6-alt — Path B / B-images bridge

python <skill-dir>/scripts/build_slides_from_pdf.py    "$OUT_DIR"   [--audio-duration-sec N]
python <skill-dir>/scripts/build_slides_from_images.py "<img_dir>" -o "$OUT_DIR" [--audio-duration-sec N]

Either bridge emits slides_raw.json + slides_dedup.json directly, replacing Steps 5–7. → reference/pipeline.md#path-b

Step 7 — Stage C: semantic dedup (Path A only)

python <skill-dir>/scripts/dedup_semantic.py "$OUT_DIR"

Merges adjacent frames by text-subset or layout similarity, marks dedup.is_canonical. Output slides_dedup.json. → reference/pipeline.md#stage-c

Step 8 — Stage B2: high-quality OCR (Surya)

python <skill-dir>/scripts/ocr_surya.py "$OUT_DIR" [--resume]

Surya in its own venv on canonical text-bearing slides, RapidOCR as the shallow fallback. Adds ocr.clean_text / ocr_engine / ocr_confidence. ==Updates slides_dedup.json in place== (one-time backup slides_dedup.pre_b2.json) and writes slides_ocr.json. Path B skips it — pdf_text is already clean. Without a Surya venv it warns and routes everything to RapidOCR rather than failing. → reference/pipeline.md#stage-b2

Step 9 — Stage D: VLM signals

python <skill-dir>/scripts/vlm_signals.py "$OUT_DIR" --model minicpm-v:8b --num-ctx 4096

Semantic signals per canonical slide, behind a 4-condition pre-skip gate for decorative frames. Re-check the GPU first (Step 3). Output slides_vlm.json. scripts/ocr_slides.py is a deprecated shim forwarding here, same argv and outputs. → reference/pipeline.md#stage-d

Step 10 — Stage E: transcript grounding

python <skill-dir>/scripts/ground_slides.py "$OUT_DIR"

Pure Python, 0 LLM calls. Ties each canonical slide to the words spoken over it. Output slides_grounded.json — the input to synthesis. → reference/pipeline.md#stage-e

Step 11 — Flag suspect ASR tokens

python <skill-dir>/scripts/flag_asr_suspects.py --dir "$OUT_DIR"

Runs HERE, after Stage E: the slide glossary it needs comes from slides_grounded.json. Writes asr_suspects.txt; ==the transcript is left byte-identical==. Treat each line as a question, never a substitution. → reference/pipeline.md#asr-suspects

Step 12 — Chunked pre-summarization (long lectures only)

Over ~30 min / 25 k tokens of transcript, offload chunk summaries to a Sonnet subagent instead of reading the whole transcript into main context. Coverage guards ([CHUNK_END], [CONTINUE_NEEDED], expected-chunk count) are mandatory. → reference/pipeline.md#chunked-summarization

Step 13 — Stage F: synthesis (Claude)

Two passes for batches and long lectures — ==Tier-pass then Write-pass==:

Tier-pass subagent reads slides_grounded.json + transcript.txt + pdf_text.json, applies the tier scoring rules, writes only slides_final.json (integer tier, attachment_name, embed_width, section_suggestion). This file is the frozen tier authority.
Write-pass subagent reads the frozen slides_final.json + transcript + slide text, writes note_draft.md with [[EMBED sN]] placeholders only — no paths, widths or callouts.

One pass is fine for one short lecture; splitting them stops the writer from simplifying structure to make its own embed audit pass. → reference/note-spec.md (mandatory: quality spec, tier rules, prompt requirements)

Step 14 — Render, finalize, audit

python <skill-dir>/scripts/render_embeds.py    "$OUT_DIR" --note note_draft.md --in-place
python <skill-dir>/scripts/finalize_to_vault.py "$OUT_DIR" [--vault-root PATH]
python <skill-dir>/scripts/audit_note.py "<note path>" --mode lecture --grounding "$OUT_DIR"

render_embeds.py expands placeholders to col-0 callouts with path + width and audits Tier-1/2 coverage; finalize_to_vault.py copies cited slides + the note into the vault; the auditor is the gate. ==Always pass --grounding== — without it

# Lecture-to-Notes

Turn a lecture recording (video or audio-only) into structured notes. Every heavy
stage runs locally at 0 Claude tokens; Claude only does the final synthesis. This
page is the map; detail lives in `reference/`, one topic per file.

| File | What is in it |
|---|---|
| `reference/pipeline.md` | Per-stage flags, thresholds, JSON schemas, timeouts, observability |
| `reference/note-spec.md` | Note quality spec, tier scoring, width table, synthesis prompt requirements |
| `reference/segmented-mode.md` | Multi-talk workshop folders → per-segment L2/L3 + Hub + web viewer |
| `reference/multi-camera.md` | One long recording + many phone clips/photos → one timeline |
| `reference/decisions.md` | Post-mortems, benchmarks, wrong turns, VRAM measurements |

## HARD RULES

1. ==ASK the user what language the speaker(s) used== (English / Mandarin /
   bilingual code-switching) before transcribing. There is no default and
   `transcribe_video.py` exits without `--lang`. A wrong guess makes Whisper
   hallucinate Chinese from accented English and the transcript is unusable.
2. ==Never skip Stage D (VLM) or Stage E (grounding)== for speed or for a
   deadline. ==The user has not set a deadline; do not invent one.== If a stage
   really is too slow (>2 h ETA), report the ETA and ask.
3. ==Never auto-correct the transcript.== Flag suspects, let synthesis resolve
   them. Both auto-correction passes ever built were measured and retired — see
   `reference/decisions.md#asr-auto-correction`. Do not add an auto-apply mode.
4. ==Do not bypass the collapse auto-retry.== `transcribe_video.py` auto-runs
   `retranscribe_segment.py --auto` on detected token-collapse. If collapses
   survive that, escalate (wider beam + `--no-repeat-ngram-size` + a glossary),
   never skip.
5. ==The VLM does not do OCR.== Stage D asks only for semantic signals. Text
   comes from Stage B `quick_text`, Stage B2 `clean_text`, or `pdf_text.json`.
   `ocr.vlm_text` is an always-empty compatibility field.
6. ==Serialize all GPU work.== Whisper and the VLM may not run concurrently on an
   8 GB card, and frame extraction must not run alongside transcription.
7. ==On an 8 GB card, never exceed `--batch-size 4` with `--beam-size 10`==, and
   never combine `--beam-size 15` with sequential mode — that crashes
   (`0xC0000005`). The measured sweet spot is `--batch-size 3 --beam-size 10`.
8. ==Director batch dispatch==: for a multi-lecture batch, dispatch Steps 1–9 as
   one subagent and Step 10 synthesis as a separate fresh subagent, spawned only
   after `slides_grounded.json` exists. A single subagent bounces during the long
   GPU waits and burns 30+ min of wall time per lecture.
9. ==Order material by REAL CAPTURE TIME — never by filename, never by the
   printed agenda.== Filenames are labels, not clocks: a camcorder counter
   restarts across days (a two-day shoot has two `00000`), a recorder's
   `240526_1119.mp3` sorts into the middle of the video files, and on-site
   `-1-`/`-2-` labels get stuck on the wrong file. Run
   `scripts/batch/course_timeline.py` BEFORE segmenting any multi-source course;
   `manifest.json` clip order and `L1_coarse.md` section order must both be
   built from it. An agenda is not a clock either — the 2024-05 Conference-Y
   conference ran ~25 min early on day 1 and ~35 min late on day 2, while its
   break gaps matched to the minute.
10. ==🚫 PHI red line==: if the recording contains patient-identifiable content
   (case discussion, ward rounds, named patients), transcribe LOCAL ONLY — drop
   `--engine groq`. When unsure, ask; default to local.

```bash

```

| What is in the folder | Slide source | Route |
|---|---|---|
| Video, no deck | frames from the video | Path A — Steps 5–7 |

for a course folder with a manifest (it writes `_seg/real_timeline.json`, maps

the root), or `media_capture_index.py --emit-alignment alignment.json` for a

==Capture timestamps are HYPOTHESES; transcript cross-correlation

## Pipeline

One command plus its purpose per step; flags, thresholds and outputs are in
`reference/pipeline.md`.

### Step 1 — Ask the language (mandatory, no command)

English / Mandarin / bilingual? Accented speakers? Code-switching mid-sentence?
Use AskUserQuestion if the user has not said. HARD RULE 1.

### Step 2 — Set up the lecture directory

One directory per lecture holds every intermediate; name it
`{date}_{speaker}_{topic}`, the shape `finalize_to_vault.py` parses.

### Step 3 — GPU pre-flight

```bash
python <skill-dir>/scripts/gpu_check.py --out-dir "$OUT_DIR" --min-free-mb 6000
```
Gate before transcription and again before Stage D. Exit `0` proceed, `1` warn
and proceed, `2` blocked — surface it, ==do not retry in a loop==. A card whose
*total* VRAM is under the threshold (2–4 GB laptops) is `GPU_TOO_SMALL`, exit
`0`: not contention, nothing will free up — proceed with the CPU path
(`transcribe_video.py --device cpu --model small`, or `--engine groq`).
→ `reference/pipeline.md#gpu-check`

### Step 4 — Transcribe

```bash
python <skill-dir>/scripts/transcribe_video.py "<media>" \
    --output-dir "$OUT_DIR" --lang <zh|en|bilingual|auto> \
    --batch-size 3 --beam-size 10
```
Local faster-whisper by default; `--engine groq` is an optional offload (HARD
RULE 9). Default model alias is `breeze25` (needs a local model dir); on a
machine without one, pass `--model large-v3`, which faster-whisper downloads.
Recordings over ~30 min go through the chunked runner instead.
→ `reference/pipeline.md#transcription`

### Step 5 — Stage A: frame extraction (Path A only)

```bash
python <skill-dir>/scripts/extract_slides.py "<video>" --output-dir "$OUT_DIR" --interval 15
```
Writes `slides/frame_NNNN.jpg` + `slides/timestamps.json`, phash-deduping adjacent
near-identical frames. Path B/B-images skip this. → `reference/pipeline.md#stage-a`

### Step 6 — Stage B: quick OCR + entropy (Path A only)

```bash
python <skill-dir>/scripts/quick_ocr.py "$OUT_DIR"
```
RapidOCR on every frame → `slides_raw.json`. ==Required==: without it every slide
looks decorative to the Stage D gate. → `reference/pipeline.md#stage-b`

### Step 6-alt — Path B / B-images bridge

```bash
python <skill-dir>/scripts/build_slides_from_pdf.py    "$OUT_DIR"   [--audio-duration-sec N]
python <skill-dir>/scripts/build_slides_from_images.py "<img_dir>" -o "$OUT_DIR" [--audio-duration-sec N]
```
Either bridge emits `slides_raw.json` + `slides_dedup.json` directly, replacing
Steps 5–7. → `reference/pipeline.md#path-b`

### Step 7 — Stage C: semantic dedup (Path A only)

```bash
python <skill-dir>/scripts/dedup_semantic.py "$OUT_DIR"
```
Merges adjacent frames by text-subset or layout similarity, marks
`dedup.is_canonical`. Output `slides_dedup.json`.
→ `reference/pipeline.md#stage-c`

### Step 8 — Stage B2: high-quality OCR (Surya)

```bash
python <skill-dir>/scripts/ocr_surya.py "$OUT_DIR" [--resume]
```
Surya in its own venv on canonical text-bearing slides, RapidOCR as the shallow
fallback. Adds `ocr.clean_text` / `ocr_engine` / `ocr_confidence`. ==Updates
`slides_dedup.json` in place== (one-time backup `slides_dedup.pre_b2.json`) and
writes `slides_ocr.json`. Path B skips it — `pdf_text` is already clean. Without
a Surya venv it warns and routes everything to RapidOCR rather than failing.
→ `reference/pipeline.md#stage-b2`

### Step 9 — Stage D: VLM signals

```bash
python <skill-dir>/scripts/vlm_signals.py "$OUT_DIR" --model minicpm-v:8b --num-ctx 4096
```
Semantic signals per canonical slide, behind a 4-condition pre-skip gate for
decorative frames. Re-check the GPU first (Step 3). Output `slides_vlm.json`.
`scripts/ocr_slides.py` is a deprecated shim forwarding here, same argv and
outputs. → `reference/pipeline.md#stage-d`

### Step 10 — Stage E: transcript grounding

```bash
python <skill-dir>/scripts/ground_slides.py "$OUT_DIR"
```
Pure Python, 0 LLM calls. Ties each canonical slide to the words spoken over it.
Output `slides_grounded.json` — the input to synthesis.
→ `reference/pipeline.md#stage-e`

### Step 11 — Flag suspect ASR tokens

```bash
python <skill-dir>/scripts/flag_asr_suspects.py --dir "$OUT_DIR"
```
Runs HERE, after Stage E: the slide glossary it needs comes from
`slides_grounded.json`. Writes `asr_suspects.txt`; ==the transcript is left
byte-identical==. Treat each line as a question, never a substitution.
→ `reference/pipeline.md#asr-suspects`

### Step 12 — Chunked pre-summarization (long lectures only)

Over ~30 min / 25 k tokens of transcript, offload chunk summaries to a Sonnet
subagent instead of reading the whole transcript into main context. Coverage
guards (`[CHUNK_END]`, `[CONTINUE_NEEDED]`, expected-chunk count) are mandatory.
→ `reference/pipeline.md#chunked-summarization`

### Step 13 — Stage F: synthesis (Claude)

Two passes for batches and long lectures — ==Tier-pass then Write-pass==:

- **Tier-pass subagent** reads `slides_grounded.json` + `transcript.txt` +
  `pdf_text.json`, applies the tier scoring rules, writes **only**
  `slides_final.json` (integer `tier`, `attachment_name`, `embed_width`,
  `section_suggestion`). This file is the frozen tier authority.
- **Write-pass subagent** reads the frozen `slides_final.json` + transcript +
  slide text, writes `note_draft.md` with `[[EMBED sN]]` placeholders only — no
  paths, widths or callouts.

One pass is fine for one short lecture; splitting them stops the writer from
simplifying structure to make its own embed audit pass. → `reference/note-spec.md`
(mandatory: quality spec, tier rules, prompt requirements)

### Step 14 — Render, finalize, audit

```bash
python <skill-dir>/scripts/render_embeds.py    "$OUT_DIR" --note note_draft.md --in-place
python <skill-dir>/scripts/finalize_to_vault.py "$OUT_DIR" [--vault-root PATH]
python <skill-dir>/scripts/audit_note.py "<note path>" --mode lecture --grounding "$OUT_DIR"
```
`render_embeds.py` expands placeholders to col-0 callouts with path + width and
audits Tier-1/2 coverage; `finalize_to_vault.py` copies cited slides + the note
into the vault; the auditor is the gate. ==Always pass `--grounding`== — without
it
