The broad QA Matrix run passed 23 files and 220 tests, with one unrelated current-main failure in extensions/qa-matrix/src/cli.test.ts. Its expected list omits seven shared-flow scenarios now present on the Matrix adapter; the exact assertion failure reproduces after restoring clean origin/main.

Behavior is unchanged: all nine declarations remain intact for their local callers; only unused export modifiers are removed.

Merged via squash.
