Per-file type-only fixes surfaced after the Supabase client was correctly
typed. All fixes preserve runtime behavior; no any/ts-ignore/ts-expect-error.
- lib/supabase/client.ts: annotate the browser client as SupabaseClient<Database>
(same ssr/js drift as server.ts; fixes it centrally for all callers).
- Supabase embedded-select joins whose FK metadata is missing from the
generated types are bridged with `as unknown as <target>` + a TODO to remove
after regenerating types/database.ts.
- setState optimistic-update variance and raw <select> enum values cast to the
precise element/union type; .insert payload fields (Json, enums) given the
precise column type via satisfies/field casts.
- Added narrowing guards where a value was legitimately nullable (comms channel,
public form page) without changing the intended path.
The 14 remaining errors are confined to the four files fixed in Phase B (real
bugs + the tautological actions.test rewrite). 639 tests still green.
