List storage slots

A committed terminal rejection returns REST 409 storage_recovery_rejected or MCP isError with strict error.rejection (outcome, original operationId, code, inventoryRevision). Only recovery_plan_conflict and recovery_dependency_conflict are terminal. Accepted/rejected exact replay precedes mutable plan reconstruction but requires current authority. Preserve unknown requests; status, billing errors and cancellation are not proof. After proof, obtain a fresh complete current owner/session read and explicitly discard, or review a new preview and confirm a new operationId. MCP outputSchema describes accepted receipts only; holofolder.com/errorSchemas metadata declares errors. Apply the exact confirmed version-2 default-creation plan with explicit replacement and stable operationId. Unsupported dependencies and conflicts reject atomically; no legacy fallback. Required permissions: `collection:read`, `collection:write`, `binders:write`. MCP tool: `apply_storage_recovery_v2`.
