Retroactive provenance discipline on the wider event-type set. Of the genuinely new event types in Layer B (project_draft_started, draft_saved, wizard_step_completed, draft_resumed, draft_abandoned, draft_promoted_to_project, resumed_from_draft, discovery_prompt_generated, claude_drill_started, discovery_answer_logged, ui_launch_event, amendment_applied_to_rules), only four were explicitly named in council convergence on poll 69965acc: draft_saved, draft_abandoned, resumed_from_draft, ui_launch_event. The remaining seven (and the optional eighth amendment_applied_to_rules) were Claude's synthesis-time elaboration to close audit-chain reconstructability at finer granularity. Per Deepseek's discipline ask in poll b82e9fff — 'synthesis is a mirror not a generative layer' — these elaborations are surfaced retroactively as amendment_proposed, amendment-gated under FORCED_RULE_PO_06, and Cycle 1 ratifies the final list before schema migration.
