Restore Readiness State Matrix

Priority	Input condition	State	Reason	Next safe action
1	No backup set selected	blocked	source_required	review_backup_selection
2	Backup source has no usable payload	blocked	source_unusable	review_backup_selection
3	Scope is not defined	needs_preparation	scope_required	define_scope
4	Required group mappings remain unresolved	needs_preparation	group_mapping_required	review_group_mappings
5	Checks evidence is missing	blocked	checks_not_run	run_readiness_checks
6	Checks evidence is stale/invalidated	blocked	checks_stale	run_readiness_checks
7	Current checks have blockers	blocked	checks_blocking	review_validation_blockers
8	Preview evidence is missing	needs_preparation	preview_missing	generate_preview
9	Preview evidence is stale/invalidated	needs_preparation	preview_stale	regenerate_preview
10	Checks and preview are current, but execution prerequisites are blocked	blocked	execution_prerequisite_blocked	review_validation_blockers
11	Checks and preview are current and execution prerequisites are available	ready_for_confirmation	ready_for_confirmation	continue_to_confirmation
12	RestoreRun is pending/queued/running	executing	execution_in_progress	open_operation
13	RestoreRun is completed/partial/completed_with_errors	completed	execution_completed	inspect_restore_results or inspect_evidence
14	RestoreRun is failed	failed	execution_failed	inspect_restore_results
15	RestoreRun is cancelled/aborted	cancelled	execution_cancelled	inspect_restore_results

Checks are intentionally evaluated before preview so a stale checks basis cannot be hidden by a current preview basis.
