The #1015 V-SES-03 edit replaced the vocabulary validation loop body and
dropped the trailing vocab_rows.append(), so specialization_vocabulary was
inserted with 0 rows even though per-system UPSERTs (which read the dict
directly via valid_spec_ids) still succeeded. regen-db reported
'vocab 0 | economic 27 | ...'. Restored the append at the end of the loop.
Verified: regen-db now writes 27 vocab rows + 27/27 economic/cultural;
spot checks financial_hub=NonPhysical/Specialist, Ran=breadbasket.
