Soul pass 7, S7-3 and S7-4, P7-3 and P7-5.
Columns (S7-3): every declared column must be under a deterministic
collation. A case-insensitive provider_user_id whose key index compares
under "C" passed, and the store's own lookups then matched other users'
ids.
The check becomes checkSchemaRequirements(pool, requirements), with
Heimdall's store calling it with HEIMDALL_SCHEMA_REQUIREMENTS (its tables,
columns, keys and privileges). That seam lets a live test check a
predicate Postgres prints differently from how it is written (a literal
gains its cast): the check must still pass, so comparing the raw text
instead of the printed form (P7-3's Y1) now fails.
A role that may not create temporary tables was refused with 42501 and
told to check GC_ACCESS_DATABASE_URL_FILE (P7-5). The predicate printer now
refuses it as SCHEMA_TEMP_PRIVILEGE, and startup says to grant the role
TEMPORARY on its database, in fixed text.
New fixtures (S7-4): a case-insensitive collation on a key's first column
(Y3), NOT NULL added to a nullable column of linked_identities (Y5), and
every privilege on auth_completions except on attempt_id (Y8) are refused;
a key index that INCLUDEs an undeclared case-insensitive column starts
(Y4).
