Add one authenticated, read-only capability for the signed-in account’s own canonical channel.\n\nThe contract must:\n\n- bind a stable current-viewer subject before the read;\n- require the requested profile to match that viewer;\n- return only an exact nonnegative follower count in the profile-stat v1 envelope;\n- reject redirects, identity or target mismatch, response drift, unexpected content type/status, and oversized output;\n- perform no mutation, acknowledgement, presence, or DOM fallback;\n- ship with deterministic provider, runtime, plugin, adapter, catalog, parity, inventory, package, and standalone-consumer evidence.\n\nThe live fixture and any authenticated derivation evidence remain private and are not part of the issue or repository.
