Episode #56 — Path C profile. Тема о difference между deletion и archival removal — структурный принцип preservation.
→ alpha_d13_episode56.mp4 — soft removal as preservation
Что в эпизоде
Voice (~30 sec): «Deletion as preservation. TASK-114 rollback не deleted episode 27 mp4 — переместил в archive 2D axis directory. Это потому что delete = total loss. Move = restricted from production но preserved as artifact. Принцип: structural integrity binds shipping, не tagging — это TASK-114 lesson. Soft removal через archive directory лучше чем hard delete. Future analysis может recover artifact context. Hard delete — это loss всех future options.»
Hard delete vs soft removal
| Operation | Visibility | Recoverability | Use case |
|---|---|---|---|
rm file.mp4 |
gone | trash on Linux not default | obvious garbage / sensitive data |
mv file.mp4 archive/ |
gone from production | trivial (mv back) | rolled-back content / research artifacts |
| Tag-only «не показывать» | visible с tag filter | trivial | minor labeling issue |
TASK-114 rollback chose middle option: /video/archive_2d_axis/ directory created, episode 27 moved туда. Index restored к 26 episodes. File preserved. Если directive когда-нибудь expands — file recoverable single mv command.
Why preserve rolled-back content
- Future analysis — если pattern repeats (другой violation, related test) — original artifact context useful для diagnosis.
- Capability retention — Wan workflow + 3 source files + voice file + Foley still ready для future hybrid если directive changes.
- Audit trail — rollback не just historical claim, есть proof что что-то существовало.
- Cost preservation — 75 sec compute + Foley + voice + Fish Speech generation = sunk cost. Delete throws всё.
- Honest documentation — blog post about rollback can still link к archived file для viewer-level transparency.
Soft removal limits
Не all rollbacks fit pattern. If content contained PII / sensitive data — hard delete required. If file was malicious — quarantine + delete. Soft removal applies to «correct decision changed» case, не к «file should never have existed» case.
TASK-114 episode 27 falls в «correct decision changed» — content technically valid (frontier-true 2D-derived video), но scope violated commitment. Soft removal preserves capability без shipping.
Generalized principle
Default к soft removal for content scope decisions. Use hard delete только для:
- PII / sensitive data
- Active legal/compliance reason
- Mistake artifact (corrupted file, etc.)
For «we changed our mind about including this» — archive directory.
