The embedding loop shares the wall-clock entered_at and the same stall
verdict, so it failed the same way through a different path: one timed-out
attempt, then any round with no runnable source, and _on_no_runnable
declared the scope dead. Issue #8 only recorded the chat path; the
regression test pins this one.
Mutation testing showed the negative structured-retries and expected-dim checks
in the env parsing path could be deleted with every test still passing. Their
value is the env key name in the message, so they need tests that assert it.
Changelog now states the real scope of this release and warns that normalising
scope moves the Redis keys, the one change here that silently relocates runtime
state. Records the breaker threshold derivation as deliberately env-only so it
does not resurface as another round.
