BEHAVE-EXTRACTOR.md Phase B Step B.3. Replaces the prototype's
two-line "0 vs >0 backspaces" placeholder with a backspace-timing
classifier that honours the registry's full vocabulary.
* SessionContext gains backspace_count, backspace_iats (IAT from
each backspace back to the preceding non-backspace input event),
and kill_line_count (^U / ^W). Built by _scan_correction_signals,
which retains only counts and timing aggregates — no character
data leaves the helper, in line with the BEHAVE PII discipline.
* _features/motor.py:error_correction(ctx) emits one Observation
in {immediate, deferred, absent, route_around}.
- 0 backspaces + ≥1 ^U/^W → route_around (rewrite, not correct)
- 0 backspaces + 0 kill-lines → absent
- backspaces with median IAT ≤ 500 ms → immediate
- slower → deferred
Confidence 0.65 / 0.65 / 0.55 / 0.55.
* < 3 inputs → skip emit.
* Calibration grid widened to include motor.error_correction;
green across all five shards.
Tests cover all four buckets, the < 3 inputs skip, and the PII
regression (raw command body never appears in the serialised
observation).
