Baseline — manifest piece unit_kind distribution

All 16 pieces:

unit_kind = 'law_section' (count=16)
addresses = DIEU-39-v2.3#preamble, #sec-0-..., #sec-1-26-..., ..., #changelog

This is the root pathology — law_section is NOT in dot_config vocab.unit_kind.* (which only contains design_doc_section and law_unit).

Baseline — pre-fix function md5

Backup

$ ssh contabo "docker exec postgres pg_dump -U workflow_admin -d directus --no-owner --no-privileges -f /tmp/pre_dieu39_unit_kind_fix_20260527.sql"
$ ssh contabo "docker exec postgres bash -c 'ls -la /tmp/pre_dieu39_unit_kind_fix_20260527.sql && md5sum /tmp/pre_dieu39_unit_kind_fix_20260527.sql'"

2d21965b13a46ae32e29ccc6f48308fc  /tmp/pre_dieu39_unit_kind_fix_20260527.sql

Size 921,852,206 bytes, md5 2d21965b13a46ae32e29ccc6f48308fc. Compared to mig 054 pg_dump (84,104,933 bytes per memory), this dump is much larger because it includes the full directus runtime — both are valid for their snapshot times.

Conclusion

HARD GATE 0 PASS. All required objects exist; write channel verified; backup taken. Proceeding to PHASE B root-cause classification.
