Why

COUNT over a qualified or modified star converted to count(*), which counts every row. Snowflake counts other rows for these shapes: C's held receipts show COUNT(alias.) giving 3, and COUNT( EXCLUDE …) and COUNT(* ILIKE …) giving 4, where count(*) gives 5. That is a wrong answer. Until a conversion is recorded for each shape, they refuse.

Changes

• COUNT refuses (SQ0003 fn:COUNT) over a qualified star (t.*) and over a star with EXCLUDE, ILIKE, RENAME or REPLACE, including DISTINCT and windowed forms. COUNT(*), COUNT(x), COUNT(DISTINCT x) and COUNT(DISTINCT x, y) are unchanged.
• The call spelling of COUNT treats only a bare * as COUNT(*).
• The COUNT rule's conditions say so.

Other calls over a star were checked and need no change. ARRAY_AGG, OBJECT_AGG, MAX, SUM, MIN_BY, ANY_VALUE, COUNT_IF, HASH_AGG, APPROX_COUNT_DISTINCT, LISTAGG and ARRAY_UNIQUE_AGG over a qualified or modified star already refuse. OBJECT_CONSTRUCT, HASH and ARRAY_CONSTRUCT expand the star themselves, honour EXCLUDE, and refuse ILIKE, RENAME and REPLACE.

Verification

• A CLI test converts each of the seven shapes (t.*, EXCLUDE, ILIKE, RENAME, t.* with EXCLUDE, DISTINCT t.*, and t.* over a window) and checks that it refuses.
• make check-ci, make test-rust and make verify-recorded.

Gate at 144dc45 (based on main 287f275):

• make check-ci: exit 0
• make test-rust: exit 0
• make verify-recorded: 11,779 cases, 0 failed; translation baseline unchanged, nothing regressed
• Hygiene scan: clean
• One-round audit: approved, nothing to change. Every modified-star COUNT spelling probed now refuses, and COUNT(), COUNT(a), COUNT(DISTINCT a[, b]) and windowed COUNT() are unchanged.

The hosted CI run did not start (Actions billing), so this local gate stands in for it.
