decodeJson/decodeJsonResult/encodeJson read and write a JSON-in-TEXT column against the schema and fallback declared for it in db/json-columns.ts, and log a row that does not decode. reservations.metadata, the OAuth scope and redirect lists, consents, API token scopes, MFA backup codes, journey entry tags and pros/cons and poll options go through it. Readers that used to throw on a broken row (a hotel update, the ICS export, the price mirror, the OAuth token and session reads, a consent, a journey entry, a poll) now take the tolerant fallback the other readers of the same column already used.
