server/interruptibility.py — programmatic check that the pipeline task is
configured with allow_interruptions=True (D-008 abort-and-yield). The manual
test (speaking during AI speech cuts it off) is documented in
docs/latency-report.md; the automated test confirms the flag is set.
server/scenarios/classifier.py — classify_branch() uses
deepseek-v4-flash:cloud no-think (D-020) as LLM-as-judge to classify the
learner's turn transcripts into accept_resolution or escalate at session end,
OFFLINE from the voice loop (D-P1-05, G-002 post-hoc classification). Parses
the LLM's JSON response leniently (code fences, unknown-id fallback, malformed
JSON scan). classify_branch_sync_heuristic() is a rule-based fallback for
tests/e2e when no API key is present. 11 tests pass (interruptibility flag
on/off/missing; classifier accept/escalate scripted transcripts; JSON parse
valid/code-fenced/unknown-id/malformed; fake-LLM async classify; offline
structural assertion).
