Memory drift detected at baseline (live ≠ memory)

memory said	live observed
5-alias body md5 eb7e8ce2… stable	6 aliases present; prosrc md5 750b06b610f50065f1117961813d9df4
alias surface: fn_iu_op_mark	live name: fn_iu_op_mark_file
no fn_iu_op_cleanup_dry_run mentioned	exists, but operates on iu_core.iu_staging_record (staging cleanup), NOT on public.cut_request
fn_cut_request_add(text,text,text,jsonb)	live signature: fn_cut_request_add(text,text,text)
cut_request.id	live PK column: cut_request_id

Drift was mechanical (signatures + memory index slugs), not semantic. All surfaces still satisfy contracts described in mig 052. Memory index will be updated post-pack.

pg_dump pre-apply backup

/tmp/pre_iu_cut_runtime_harden_20260526T170620Z.dump
size: 83,501,714 bytes
delta vs mig 052 close: +16,841 B (background event_outbox + job_queue)

pg_dump post-apply backup

/tmp/post_iu_cut_runtime_harden_20260526T171912Z.dump
size: 83,508,299 bytes
delta vs pre: +6,585 B (3 new function bodies + queue_heartbeat row + transitions)

Both pg_dump files preserved on host for rollback fidelity.
