BEHAVE-EXTRACTOR.md Phase B Step B.4. First implementation —
prototype doesn't ship this primitive.
* SessionContext gains intra_command_iats: per-command tuple of
IATs between consecutive input events whose timestamps fall
inside [cmd.start_ts, cmd.end_ts). Excludes the terminator IAT.
Built by _per_command_iats.
* _features/motor.py:command_chunking(ctx) emits one Observation
in {fluent, fragmented, single_command}.
- 0 commands → skip emit
- 1 command → single_command (registry-allowed point)
- ≥2 commands → median CV across per-command typed-IATs;
< CMD_CHUNKING_FLUENT_CV_MAX (0.50) → fluent, else fragmented
- paste-only sessions (no command has ≥3 typed IATs) → skip emit
(no honest within-command rhythm to measure)
Confidence 0.80 / 0.65 / 0.60.
* Calibration grid widened to include motor.command_chunking;
green across all five shards. Phase B primitive set complete.
Tests: no commands → skip, 1 command → single_command, uniform
typing → fluent, alternating fast/slow → fragmented, paste-only
multi-command → skip emit.
