BEHAVE-EXTRACTOR.md Phase A Step 2. The first primitive — picked
first because it has the highest discriminative value (HUMAN vs
everyone) and the simplest implementation (paste-event ratio over
total inputs).
* _features/motor.py:input_modality(ctx) emits one Observation
per session in {typed, pasted, mixed} with confidence 0.75 / 0.70.
* _features/_emit.py centralises the make_observation helper so
every feature module gets the same Window/source/evidence_ref
boilerplate without copy-paste.
* Thresholds inherited from the prototype's calibration history
(MODALITY_PASTED_MIN=0.40, MODALITY_TYPED_MAX=0.05).
* Zero-input session skips emission — registry doesn't admit
"unknown" here.
Tests: pure-typed → typed, pure-pasted → pasted, mixed → mixed,
output-only session → no observation, full envelope round-trip.

"""Step 0 smoke: prove the wiring before any logic.
|
|
|
|
Before any feature function lands, verify:
|
|
|
|
* the public ``extract_session`` import path resolves;
|
|
* an empty event stream yields zero observations and a well-formed
|
|
zero-duration ``SessionContext``;
|
|
* a single input event yields a context with ``t_start == t_end``
|
|
and ``duration_s == 0.0``;
|
|
* a multi-event stream populates ``t_start`` / ``t_end`` /
|
|
``duration_s`` correctly and routes events into the
|
|
``input_events`` / ``output_events`` slots by kind;
|
|
* ``FEATURES`` is empty at Step 0 — the empty contract is the gate
|
|
that the next step must intentionally break.
