Production GET /api/cv/outline returned 500 "Unknown column
'c.LongTailJson'". CareerProfiles is reconciler-owned, but the
reconciler's CREATE TABLE (both the SQLite and MySQL branches) only
listed Id, OwnerUserId, ProfileJson, Version, CreatedAtUtc, UpdatedAtUtc.
LongTailJson was added to the CareerProfile model in Phase 3 but neither
CREATE was updated and no column-repair existed, so:
- existing databases (prod): the MySQL CREATE is guarded on
!HasMySqlTable, so it never runs once the table exists, and nothing
adds the column -> LoadStructuredAsync selects a column that isn't
there.
- fresh databases: the CREATE itself omitted the column, so even a brand
new MariaDB/SQLite was missing it. The 420 tests never caught this
because they build tables from the EF model, not the reconciler DDL.
The release audit missed it because it never exercised /api/cv/outline.
Add LongTailJson to both CREATE statements and add an additive repair
(EnsureColumn / EnsureMySqlColumn) for existing tables. DEFAULT ''
backfills existing rows and matches the non-nullable model property.
This is the sanctioned reconciler repair path, not a manual ALTER, and
preserves existing data (ADD COLUMN is non-destructive).
Verified on a real MariaDB 11 container: an existing 6-column
CareerProfiles gains LongTailJson on startup (repair path), a fresh DB
gets it from the CREATE (longtext), and GET /api/cv/outline returns 200.
