Consolidates 5 name-groups with synthetic null.<8hex> codes (minted by mig 136 from legacy submission_code IS NULL rows) onto a single canonical PE per name. 9 duplicate rows archived (is_active=false, lifecycle_state='archived'), 9 sequencing_rules reparented onto their canonical procedural_event. Worst offender: "Mängelbeseitigung / Zahlung" 6 → 1. Audit-first: per-row RAISE NOTICE before the writes, plus snapshots in paliad.procedural_events_pre_151 and paliad.sequencing_rules_pre_151 (same TX, mirrors precedent pre_091/093/095/098/140). Post-asserts that no name-group still has >1 active+published null.* row and no sr points at an archived PE. Pre-flight schema audit confirmed no audit trigger on procedural_events or sequencing_rules (only INSTEAD OF triggers on deadline_rules_unified, which don't fire on direct table writes), 0 deadlines + 0 draft_of refs to the duplicates, and lifecycle_state has no CHECK constraint blocking 'archived'. .down.sql best-effort restores sr.procedural_event_id and reactivates the archived rows from the snapshot tables. Mig already applied to youpc paliad schema via Supabase MCP within the same TX as the applied_migrations row insert (checksum matches the embedded file); deployed binary will see version 151 as applied.
