A scenario is a JSON file under cmd/mavend/testdata/scenarios: a start
instant, a script of canned model answers, and a list of steps at "HH:MM".
Each step does one thing — say, audio, signal, arrive, tick, fault — and
then asserts on what she said, what was sent, which ecosystem services were
called, and what landed in the intake journal.
Between those boundaries the real components run: the real router cascade
(stage0, the LLM router over a scripted completer, the classifier
underneath it), the real store, the real reactive handler, the real tick
loop, and the same intake-decorated ipc.CoreAPI the daemon wires. What is
faked is only what a test cannot have: the model, the microphone, the
speaker, the delivery sink, and the ecosystem HTTP services.
Time is a single fakeClock threaded into every reader — the handler, the
intake publish stamp and tick(ctx, now) — so there is no time.Now() on the
replay path and a scenario is reproducible. TestSimulatorIsDeterministic
enforces that by replaying twice and diffing the transcripts byte for byte;
advanceTo refuses a step that goes backwards.
Two scenarios ship. morning_missed replays #284's own description: he
appears at the desk, a feed item, a mail candidate and a relayed
notification arrive through the morning, two ticks pass, and the assertions
are as much about nothing being sent at him unprompted as about what she
said. evening_degraded picks up the tier-2 pipeline case #288 deferred
here — a golden WAV through the STT seam to a written fact — and then puts
the ecosystem into 503 and checks that the proactive loop stays quiet and
that intake keeps working without it.
This is test-only code. Nothing in the production binaries changed, so the
daemon behaves identically when no scenario is running.
`make simulate` runs them verbose so the transcript is readable; `make
test` runs them with everything else.
