Two gate gaps let the t62 findings ship, and both are closed here.
A pure-AST unreachable-statement pass (scan(): pass 6, entry point
scan_unreachable()): in every statement block, a statement after
return/raise/continue/break can never run. Per-block on purpose — an `else`, an
except handler or a nested function is a different block and not dead, so the
pass stays signal. Red proof: the pre-fix connection.py, saved from HEAD, is
flagged as `connection.py:1113: unreachable-statement: return at line 1110 ends
this block`; the live tree is clean. A new counter (statement_blocks, floor 500
of ~1102) keeps the "no findings" verdict from being a pass that stopped
parsing.
The call-argument floor was 20 while the walk counted 46, so deleting a
flow-display owner from HA_CALL_OWNERS did not trip it. It is 44 now, and the
suite proves the trip: removing async_show_menu yields 40 checked arguments and
`only 40 call_args (floor: 44)`. Measured removals: show_form 25, abort 38,
show_menu 40, create_entry 41, update_entry 41 all violate; the
single-call-site async_update_reload_and_abort (45) is the one owner a count
floor cannot watch, which is why the floor sits two below the count.
Also (t62 nit a): the two comments that pinned the t40 entity-attribute finding
to ``media_player.py:828`` now name the file and the attribute instead — the
line had rotted to an unrelated property.
