Three shipped scenarios assert distinct FOB reflex properties per spec section 5.3:
- loud-barge.toml: PRIMARY barge-in path (local VAD, 20 loud frames @ 20ms = 400ms)
- quiet-advisory.toml: SECONDARY path (sub-VAD-threshold quiet frames; in the
slice-4-half standalone-wiring mode this exercises the harness's own latencies
rather than real brain ASR-VAD -- the latter deferred to post-spearhead
MockRealtimeBrain composition per spec section 8.6)
- sustained-call.toml: multi-barge / anti-fatigue check (3 loud bursts across 5 speak
cycles; the second + third bar's kill-time should drift <= 1.5x the first's).
LEARNING.md gains 5 new slice-4-half concept pointers covering: measurement discipline
(the callers clock), post-hoc dedup of noise captures, in-process concurrency sweep,
atomic accumulators with compare_exchange_weak, and pub(crate) visibility for the
percentile_ms helper used by ConcurrencyRunner's sample-level aggregation (avoiding
the interleaved-captures-corrupt-LatencyProbe-pairing problem).

LEARNING.md indexes ten concept-to-file pointers (the spec floor was
five) — the newtype pattern, exhaustive enum match, sans-IO, trait
extension seams, thiserror + hot-path match-and-continue, Arc<Mutex>
vs Arc<RwLock>, DashMap, str0m's single-mutation invariant, graceful
shutdown, include_str!. fuzz/README.md pre-paves the layout (no
hostile-bytes surface in slice 1; harnesses land at step 5 per the
out-of-scope table). README's new dev-loop section documents the
libopus FFI prerequisite and the manual e2e steps.
