Rehome 8 Cohort 3 Meeting 1 translation files from Cohort_1/Meeting_001 into Cohort_3/Meeting_001

[docxology]

• Series: TextbookGroup
• Files: 8
• Estimated time: ~45 minutes
• Labels: good-first-issue, i16-translations

Eight translation files (es, fr, it, nl, pt, ru, zh-Hans, zh-Hant) named "ActInf Textbook Group ~ Cohort 3 ~ Meeting 1 (Welcome and Onboarding)" sit in the Cohort 1, Meeting 1 item. The stem is a title-exact match for Cohort_3/Meeting_001 part G9GfOMjF4g0. Cross-item rehome.

Scope (from the triage doc, Part A):

• Item TextbookGroup/ParrPezzuloFriston2022/Cohort_1/Meeting_001 → rehome into TextbookGroup/ParrPezzuloFriston2022/Cohort_3/Meeting_001
  • 8 files, stem ActInf Textbook Group ~ Cohort 3 ~ Meeting 1 (Welcome and Onboarding) → target translations/G9GfOMjF4g0.<bcp47>.srt

Read first: docs/volunteer-transcript-tasks.md —
sections "The 30-minute task (per file)" and "Exact command pattern".

Steps, per file:

1. Verify the guessed video_id in the item's metadata.json + a YouTube spot-check of the part.
2. Confirm the language by opening the .srt (normalize legacy codes per the migration map).
3. Move with the two-step git mv into translations/<video_id>.<bcp47>.srt.
4. Append the original repo-relative path to the destination item's metadata.json previous_paths.
5. One path-scoped commit per item: translations(<series>): migrate <N> legacy files (I16 triage).

Acceptance criteria:

• every listed file moved (or deleted, if byte-identical to an already-migrated target) with previous_paths recorded
• no listed file remains in the item's Translations/ folder; empty Translations/ and translations_tmp/ removed
• spot-checked target files open as valid subtitles and match the verified part/language
