petrova_act_deregister_consumer

Remove a consumer entry from registry.yaml. Opens a PR against petrova-codes:main deleting repos[slug] and co-emits an ADR recording the deregistration rationale. Refuses unless an explicit confirm_slug matches the slug being removed. target_repo MUST be petrova-codes.

Upholds: MR-4 · MR-7 · MR-12 Side effects: Creates branch petrova/registry-edit/petrova_act_deregister_consumer/. Modifies registry.yaml (removes entry). Adds the ADR. Opens a PR labelled registry-edit + awaiting-human-merge. Does NOT auto-merge (MR-12).

Constraints

TARGET_REPO_IS_PETROVA_CODES — envelope.target_repo must be ‘petrova-codes’.
SLUG_NOT_IN_REGISTRY — params.slug must appear in registry.yaml. Otherwise nothing to remove.
CONFIRM_SLUG_MISMATCH — params.confirm_slug must match params.slug exactly. Belt-and-braces safety against fat-finger deletion.
RATIONALE_TOO_SHORT — rationale must be ≥40 chars. Deregistration is a substantive governance act.
REFUSE_SELF_DEREGISTRATION — slug must not be ‘petrova-codes’ itself — the control plane cannot deregister itself.

Input shape

slug → RepoSlug (required)
confirm_slug → RepoSlug (required) — Must equal slug. Forces an extra keystroke before a destructive op.
rationale string (required) — Written into the ADR body verbatim. ≥40 chars.

Output shape

registry_path string
adr_path string
