post-mortem
When the Gödel gate REJECTS a mutation OR a downstream review invalidates a claim,
this skill records the cause so future Executor calls skip the closed branch.
Output (single line, appended)
{"id":"F-0142","variant":"V-0427","cause":"latent_collapse",
"signature":{"vicreg_var":0.003,"slot_purity":0.31},
"closed_branches":["sparse-prior-α>1e-3"],"date":"2026-08-14"}
Field meanings
cause — short slug: latent_collapse | gate_borderline | nan_inf | regression...
signature — observed metric values at failure (lets future runs detect recurrence).
closed_branches — pattern strings the Executor must avoid; matched literally.
