FIX7 P0 — Implementation Mutation Inventory (2026-06-11)

• Authority: PLANNING_NON_AUTHORITY. Candidate target surfaces for a FUTURE execution macro. Every surface allowed_now=NO. Nothing is mutated now.
• Machine form: fix7-p0-implementation-mutation-inventory-2026-06-11.json (byte-identical to the packet's mutation-inventory.json).
• Rule: default-deny — a surface is mutable only when a future owner-OPT-4 execution macro lists it explicitly with a verified rollback.

10 candidate surfaces

#	surface	class	proposed mutation	prerequisite	rollback	allowed now
1	KB canonicalizer rev3 doc	KB_REFERENCE	operative-status marker (body unchanged)	OPT-4 + recheck	revert marker; body hash restored	NO
2	KB operative birth-blueprint (new)	KB_REFERENCE	author operative doc binding P7/V3/N6	OPT-4 + recheck	unpublish/supersede	NO
3	Packet V3 artifact set	KB_ARTIFACT	reference (not alter) sealed tree	OPT-4 + recheck	remove reference	NO
4	registry / 00-index (governance)	GOVERNANCE	register impl objects; fold deferred	OPT-4 + no T1/T2 race	addendum delete / restore revision	NO
5	production object-birth pipeline	PRODUCTION_UNKNOWN	UNKNOWN — owner/operator must scope	OPT-4 + separate prod auth	TBD (verified before apply)	NO (SURFACE-1)
6	PG	PRODUCTION_FORBIDDEN	none in planning phase	separate prod auth	DB snapshot/restore	NO (SURFACE-1)
7	Directus	PRODUCTION_FORBIDDEN	none in planning phase	separate prod auth	item delete/restore	NO (SURFACE-1)
8	registry-row (production)	PRODUCTION_FORBIDDEN	none in planning phase	separate prod auth	row delete/restore	NO (SURFACE-1)
9	system_issues	PRODUCTION_FORBIDDEN	none in planning phase	separate prod auth	restore	NO (SURFACE-1)
10	CI / workflow	CONFIG_UNKNOWN	seal-vs-bytes CI check (maybe)	OPT-4 + CI scope	revert workflow	NO (SURFACE-2)

any_surface_allowed_now = false. Forbidden surfaces (PG, Directus, registry-row, system_issues, production) are all explicitly inventoried.

Unknown surfaces are blocker-listed, not invented

The exact production "birth" surface (#5) and CI enforcement (#10) are UNKNOWN in this paper lane — no Directus/PG read was performed. They are classified UNKNOWN and carry blockers FIX7-P0-PLAN-SURFACE-1 / -SURFACE-2. No target mutation is invented. Production surfaces (#5–#9) require a separate explicit production authorization beyond the seal and beyond OPT-4.
