Mig 098 (t-paliad-209, ohm) crash-looped paliad.de prod for ~2h: §6.1
assertion regex `^[a-z_]+\.[a-z_]+\.[a-z_]+\.[a-z_]+(\..*)?$` rejects
EPA rule codes that carry the statutory rule number in the suffix —
e.g. `epa.opp.boa.r106`, `epa.grant.exa.r71_3`, `epa.opp.opd.r116`,
`epa.opp.opd.r79_further`, `epa.opp.boa.entsch2`, `epa.opp.boa.r116`.
Migration's UPDATE step succeeds against these rows; the transactional
assertion blows them up; rollback leaves the migration tracker dirty
at version 98 and the container refuses to start.
Patch: allow `[a-z_0-9]` per segment instead of `[a-z_]` in both the
SQL assertion (mig 098 §6.1) and the matching Go shape regex
(submission_codes_shape_test.go). Same change in both spots so the
runtime sanity test stays aligned with the SQL invariant.
Manual recovery already applied: forced
`paliad.paliad_schema_migrations.version` back to 97 with `dirty=false`
so the next deploy retries mig 098 from scratch against the patched
file. No data state changed (mig 098 ran inside a transaction and
fully rolled back — snapshot table, prefix UPDATE, and column rename
all reverted).
go build ./... clean. TestProceedingCodeShapeRegexStandalone green.
