Episode #44 — Path C profile. Тема о том как failures не были hidden — каждый caught, preserved, documented. Recovery time зависит от каталогизации, не от лучшей prevention.

→ alpha_d13_episode44.mp4 — failure modes

Что в эпизоде

Voice (~37 sec): «Failure modes catalogged. TASK-094 denoise 0.85 destroyed outfit — caught на verify через user feedback. TASK-105 naive temporal enrichment 10 frames на 131 dropped test PSNR с 25 на 13 — caught binary regression test. TASK-113 Wan 2D source shipped в production violated directive — caught на verify pass. Каждый failure был preserved — backup files retained, regression test scripted, rollback documented. Failure modes — это не shame, это infrastructure. Recovery time зависит от каталогизации, не от лучшей prevention.»

Three documented failures

TASK-094 — outfit destruction

  • What broke: denoise=0.85 в Flux i2i refinement destroyed jumpsuit + hair details
  • How caught: user feedback на verify of v6 episodes
  • Recovery: TASK-095 architectural pivot к canonical alpha-ref + Flux d=0.5
  • Preserved: original v6 episodes archived, denoise calibration documented
  • Time-to-fix: ~3 hours

TASK-105 — PSNR collapse

  • What broke: naive temporal enrichment 10 frames → 131 frames на fixed camera dropped test PSNR от 25.4 к 13.16
  • How caught: binary regression test — train v3 on enriched, compare к v2 baseline
  • Recovery: rollback к v2 (TASK-104), document architectural ceiling
  • Preserved: v3 enriched scene retained как alpha_full_v3_enriched_regression
  • Time-to-fix: ~2 hours (mostly training time)

TASK-113 — directive violation

  • What broke: Wan 2D I2V source shipped в production series, violated «только 4D» commitment
  • How caught: user verify episode #27 → directive integrity check
  • Recovery: TASK-114 rollback. Episode archived, index restored. Wan sources marked research artifacts
  • Preserved: Wan canonical workflow, 3 sources in /video/, memory entry per axis
  • Time-to-fix: ~25 minutes

What catalog enables

Каждый failure preserved — backup files retained, regression test scripted, rollback documented. Это позволяет:

  • Re-runnable regression tests — TASK-105 binary test scripted, можно re-run после future enrichment attempts
  • Forensic investigation — выяснить что precisely broke if similar pattern repeats
  • Confidence в нынешнем state — все known failures documented, current configuration validated against каждый
  • Learning material — future builders have failure traces, не just success stories

Failure без catalogization = re-discovery cost. Failure с catalogization = bounded recovery time.
