brokerd serves a third socket, [sockets] state (default
<home>/run/memory-broker/state.sock), bound by the same listen (dir 0700,
stale socket removed, socket 0600), one thread per connection, one
question per connection. The answer is StateStore::read: the stored taint
and flag, the store's default (private, trusted) for a session with no
file. A damaged state is an internal error with the store's text, never an
answer; other kinds are forbidden; malformed frames get read_request's
error. A new tests/serve.rs waits for an answer before reading the
startup notices (a race that failed about one run in ten under load,
before this task too).
Checks: every before block found once at ref 04 (20 edits); the new file
in the task is byte-identical to the reference; the given tests fail
before as the task says (config and state_socket do not compile;
serve_state 5 of 5 fail); gate ok with 1171 tests on the reference and on
a replay from the task text in a fresh ref-04 worktree with its own build
dir (byte-identical to the reference; removed); /tmp unchanged around the
gate; 25 mutations, 24 caught, the one missed (state bound last) changes
no tested behaviour; the socket tests 25 runs under load, 0 failures;
no task-text line over 100 characters outside tables and code.
