Records the plan for bringing coverage floors, CRAP scores, credo strict,
sobelow, boundary and mutation testing to firehose, framed as the
"internal verification" counterpart to the existing Playwright / conn /
LiveView tests.
Ordered in phases because the fast/push split (make verify + pre-push
hook, cheap precommit) is the container the other sensors wire into.
Includes the steering principles that made the stickies run work
(behavior not state, functional core/imperative shell, delete dead code,
leave defensive branches uncovered deliberately) and the deferred
decisions (CRAP threshold below 30, boundary.spec.check, Playwright in
the Lens pass).
