/**
* Fails when app code reads or inserts retired columns of a pending-drop table.
*
* A `contract-pending` marker inside a table in `packages/db/schema.ts` means the table
* still declares columns whose physical `DROP COLUMN` is deferred until the app version
* that stops emitting them is fully deployed. Drizzle compiles argless reads into an
* explicit list of EVERY declared column — `select().from(t)`, `db.query.t.findFirst()`
* without `columns`, an argless `.returning()`, a `getTableColumns(t)` spread — so a
* single argless read puts the doomed columns back into live SQL and would fail with
* 42703 against the already-migrated database for the whole cutover window of the
* contract deploy. Reads of these tables must name the columns they want.
* INSERTs also name omitted columns with DEFAULT values. Remove retired columns
* from the application table definition before the contract deploy.
*
* The audit derives everything from schema.ts itself and retires when the contract PR
* deletes the markers:
* - guarded tables = `pgTable`s carrying a drop-flavored `contract-pending(` marker;
* - each table's doomed columns = declarations tagged `@deprecated` (or carrying the
* `contract-pending` marker directly, e.g. `workspace_files.size`);
* - the sanctioned live-column builders — `omit(getTableColumns(t), [...])` and
* `const { doomed, ...live } = getTableColumns(t)` — are validated against that
* doomed set, so an omit list that misses a doomed column (including one deprecated
* later) fails here, in schema.ts's own `<table>Columns` helpers too;
* - table references resolve through every way a file can name one: a direct import, a
* renamed import, an `import * as schema` member, a `const u = alias(t, 'u')` binding,
* and an inline `.from(alias(t, 'u'))` expression.
