Lesson 250: Audacity VO Consent Metadata Receipt on BUILD_RECEIPT (2026)

Direct answer: Before July playtest highlight reels mux VO into public cuts, file vo_consent_metadata_receipt_v1.json proving each VO WAV carries consent_record_id + consent_scope + consent_expires + opt_out, values match consent_log.csv, ffprobe duration aligns with clip plan, metadata survives your mux/conversion step, and cousin playtest_clip_consent_receipt_v1 (Lesson 243) is GREEN—then promote BUILD_RECEIPT vo_consent_metadata_ok. Distinct from 243 (OBS clip concat manifest) and Lesson 234 (store stereo master).

Why this matters now (July 2027 VO in highlight reels)

July 2026–2027 teams scale playtest highlight reels—see July 2026 waveform consent trend playbook for why embedded VO metadata became non-optional beside clip consent. after Q3 capstone 244. Legal blocks reels when OBS concat passes but VO WAV exports lack consent_record_id in embedded metadata—automation cannot join waveform assets to the same rows as video clips. Lesson 243 owns clip-level consent; the Audacity VO consent preflight is the ninety-second checklist; the VO waveform consent metadata beginner tutorial is the evening walkthrough—250 is the BUILD_RECEIPT milestone for vo_consent_metadata.

Pair OBS highlight clip consent preflight and Lesson 239 tag vod_consent when facilitators flag metadata gaps.

Beginner path (export → metadata → receipt)

Time: ~54 minutes first VO line; ~12 minutes when export preset is pinned.

Developer path (gates V1–V6)

V1 — cousin receipt crosswalk

Do not duplicate C1–C6 clip proof inside VO JSON—reference cousin path and shared consent_record_id.

Key takeaways

1. 243 clip consent ≠ 250 VO metadata—both required for public reels with voice.
2. opt_out: true excludes WAV from highlight reel even if audio is usable.
3. Verify metadata after mux—V5 catches conversion strip; run the Metadata Survives Mux Challenge (M1–M6) when automation changes.
4. OBS highlight preflight consumes same consent_record_id.
5. Lesson 234 is store stereo—separate column.
6. Lesson 249 is 3D hero GLB—unrelated lane.
7. Do not glob inbox/*.mkv—Lesson 243 manifest-only concat still applies to video.
8. playtest_promotion_allowed here ≠ Q4 capstone 253.
9. Tag vod_consent via Lesson 239.
10. Forward: Lesson 251 DaVinci trailer handoff BUILD_RECEIPT.

Common mistakes

• Filing 250 while 243 cousin still fails.
• Consent fields in receipt JSON but not embedded in WAV.
• Matching wrong CSV row—V3 UUID typo.
• Skipping V5 after ffmpeg mux strips LIST chunk.
• Merging schemas into playtest_clip_consent_receipt_v1.

Troubleshooting

Mini exercise (45 minutes)

1. Export VO without metadata—confirm V2 fail.
2. Add consent fields; match consent log row.
3. Link cousin PLAYTEST_CLIP_CONSENT_RECEIPT.json.
4. Mux dry-run; verify V5 survival.
5. File receipt; BUILD_RECEIPT GREEN.

FAQ

Same as Lesson 243?
243 = video clip concat + consent log; 250 = VO WAV embedded metadata.

Same as VO consent guide?
Guide = V1–V6 checklist; 250 = BUILD_RECEIPT promotion; top 20 receipts hub lists #5 in the full playtest→public map.

Same as Lesson 234?
234 = store stereo master; 250 = playtest VO consent fields.

Need LIST chunk specifically?
Team may use LIST or iXML—document chunk_type in receipt; fields must survive your mux.

VO in public reels needs waveform-level consent proof—cousin 243, embed metadata, duration spot, conversion survival, then vo_consent_metadata_ok on BUILD_RECEIPT.
