docs(spec): FU-7 audit-trail + provenance design (GAP-17/18/19/20)
Reuse audit_log.log_action with details JSONB (X5 §4, no new table) for
end-to-end audit + block→source provenance. GAP-17 drift = blocks_stale flag
+ health-check (not fragile DOCX→blocks reparse). GAP-20 = structural
case_law_id resolution (not Hebrew citation NLP). Verified vs 3+ sources
(append-only lineage event; GitOps drift detect-don't-auto-remediate).
Pure-code, no migration.
