Run the five-class calibration grid (HUMAN / YOU-sim / LW-sim /
CLAUDE-FF / CLAUDE-CL) against the 2026-05-02 shards.
* Hard gate green for 27 primitives across all 5 shards.
* environmental.keyboard_layout moved from hard gate to
PHASE_F_CONDITIONAL_PRIMITIVES — short SSH-recon corpus maxes at
~90 typed letters per session, well below the LAYOUT_MIN_TYPED_LETTERS
(200) floor. The 200-floor stays per the per-phase "v0 ships when
honest" rule; longer-text corpora will surface the layout signal.
* Three primitives never fire on the 2026-05-02 corpus, all already
conditional and all expected:
- cognitive.error_resilience.frustration_typing
- environmental.locale
- environmental.keyboard_layout
No D / F / G threshold re-tunes needed; only the keyboard_layout
binding-set move. Phase H step log appended to BEHAVE-EXTRACTOR.md
with per-class observation counts.
Widen calibration binding from PHASE_ABCDEF_PRIMITIVES (25) to
PHASE_ABCDEFG_PRIMITIVES (28 hard). Three Phase G primitives that
emit on any session-with-commands ride the hard gate:
* operational.opsec_discipline
* operational.cleanup_behavior
* emotional_valence.stress_response
The remaining five Phase G primitives ride a new
PHASE_G_CONDITIONAL_PRIMITIVES because their sample-size floors make
them legitimately absent from short shards:
* operational.objective (≥ 3 classified commands)
* operational.multi_actor_indicators (≥ 8 commands)
* emotional_valence.arousal (typing bursts)
* emotional_valence.valence (≥ 80 typed letters)
* emotional_valence.frustration_venting (≥ 30 typed letters)
Backwards-compat alias PHASE_ABCDEF_PRIMITIVES kept. Phase G
completion log + checkbox flips in BEHAVE-EXTRACTOR.md.
Tier-A corpus delta: all 37 Tier-A primitives now emit. Phase H
(full-corpus lockdown + v0 release) is next.
Widens the binding calibration set from PHASE_ABCDE_PRIMITIVES (20)
to PHASE_ABCDEF_PRIMITIVES (25). The five new entries:
* environmental.shell_type (per-shard hard gate)
* environmental.terminal_multiplexer (per-shard hard gate)
* environmental.keyboard_layout (per-shard hard gate; PII boundary
lifted by ANTI; emits all 4 registry values)
* environmental.numpad_usage (per-shard hard gate)
* temporal.lifecycle_markers.exit_behavior (resolution of the E.4
hold; uses Command.followed_by_prompt from F.0)
environmental.locale joins a new PHASE_F_CONDITIONAL_PRIMITIVES set
(only fires on shards with an env / locale dump in the output).
Phase F completion log appended to BEHAVE-EXTRACTOR.md. The original
F.0 row hinted at D.0 subsumption; reversed in the log — D.0 is
enriched, not subsumed (regex catches errors when PS1 is suppressed).
Tier-A corpus delta: 25 of 37 primitives now emit. Phase G is next.
Widens the binding calibration set from PHASE_ABCD_PRIMITIVES (17) to
PHASE_ABCDE_PRIMITIVES (20). The three shipped Phase E primitives
(session_duration, escalation_pattern, landing_ritual) join the
per-shard hard gate.
E.4 (temporal.lifecycle_markers.exit_behavior) is held at ANTI's
direction pending Phase F.0's prompt parser — abrupt-vs-cleanup
needs exit-code visibility to be honest, and first-token membership
alone over-fires on benign rm / clear mid-session. E.4 picks up at
the tail of Phase F.
Phase E completion log appended to BEHAVE-EXTRACTOR.md; E.1-E.3
checkboxes flipped, E.4 left unchecked with a held note.
Widens the binding calibration set from PHASE_ABC_PRIMITIVES (13) to
PHASE_ABCD_PRIMITIVES (17). The four unconditional Phase D primitives
(cognitive_load, exploration_style, planning_depth, tool_vocabulary)
join the per-shard hard gate. The three error_resilience.* primitives
are conditional on at least one errored command in the shard and
tracked in PHASE_D_CONDITIONAL_PRIMITIVES — excluded from the
per-shard required-emission set, included in the cross-class
discrimination check.
cognitive_load empirical re-tune deferred to the next
BEHAVE_CALIBRATION_DIR run; v0.1 thresholds ship.
Phase D completion log appended to BEHAVE-EXTRACTOR.md; Phase D
checkboxes flipped to [x].
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).
BEHAVE-EXTRACTOR.md Phase B Step B.2. First principled
implementation — the prototype doesn't ship this primitive at all.
* _features/motor.py:motor_stability(ctx) emits one Observation
in {steady, variable, tremor}. Reuses ctx.typing_bursts from B.1.
* Tremor proxy: fraction of within-burst IATs below
TREMOR_FAST_FLOOR_S (30 ms — humans can't sustain sub-50 ms IATs).
≥ TREMOR_RATE_MIN (10%) sub-floor → tremor (double-press / motor
twitch / stuck-key).
* Otherwise median burst CV decides: < CV_STEADY_MAX → steady,
else → variable. Confidence 0.70 / 0.60 / 0.65.
* No typing bursts or fewer than 5 within-burst IATs → skip emit.
* Calibration grid widened to include motor.motor_stability; green
across all five shards.
Tests cover all three buckets + skip paths.
BEHAVE-EXTRACTOR.md Phase B Step B.1.
* SessionContext gains typing_bursts: tuple[tuple[float, ...], ...]
built by _split_typing_bursts(iats) — splits at gaps > IKI_THINK_MAX_S
(1.5s) and drops bursts of fewer than 3 IATs. Mirrors prototype's
_split_into_bursts at BEHAVE/prototype_extractors/shell/extract.py:275.
* _features/motor.py:keystroke_cadence(ctx) emits one Observation
in {steady, bursty, hunt_and_peck, machine}. Median CV across
typing bursts; mean IKI < IKI_MACHINE_MAX_S paired with CV <
CV_MACHINE_MAX → machine. Confidence 0.85/0.70/0.65/0.60 per the
prototype's calibration history.
* < MIN_INPUTS_FOR_CADENCE inputs or zero typing bursts → skip
emission. v0.1 emits only the burst-CV variant; the prototype's
NAIVE session-CV variant is parked for v0.2.
* Calibration grid widened (PHASE_A_PRIMITIVES → PHASE_AB_PRIMITIVES)
to include motor.keystroke_cadence. Grid green across all five
shards.
Tests: too-few-inputs → no emit, all-think-pauses → no burst → no
emit, uniform IATs → steady, sub-5ms → machine, mixed-pace → bursty,
extreme bimodal → hunt_and_peck.
BEHAVE-EXTRACTOR.md Phase A Step 9 — the gate. Runs the pure
engine against each of the five 2026-05-02 calibration shards and
pins the contract that all subsequent Phase B-G PRs must keep
green: every Phase A primitive (motor.input_modality,
motor.paste_burst_rate, cognitive.inter_command_latency_class,
cognitive.command_branch_diversity, cognitive.feedback_loop_engagement,
cognitive.inter_command_consistency) fires at least once per shard.
* tests/profiler/behave_shell/test_calibration_grid.py
parametrized over (shard_file, class_label) for HUMAN / YOU-sim /
LW-sim / CLAUDE-FF / CLAUDE-CL. Skips entirely when
BEHAVE_CALIBRATION_DIR is unset (CI provides the path; local dev
doesn't have to).
* Plus a discrimination-smoke check: at least one primitive
produces different majority values across present classes —
catches the "constant-output regression" failure mode where the
engine quietly degenerates to a stub.
Calibration tweak: BRANCH_DIVERSITY_LINEAR_MIN dropped from 0.80 to
0.70 to align with the prototype's empirical anchors (CLAUDE-CL ≈
0.55-0.60 adaptive; YOU-sim / CLAUDE-FF scripted recon ≈ 0.75+
linear). Test for the middle band re-pinned at the new boundary.
Per-class value pinning (e.g. HUMAN must emit
inter_command_consistency=bimodal) is intentionally NOT a hard gate
yet — v0.1 thresholds put real human sessions in "variable", and
true bimodal detection (Hartigan dip / two-peak) is registry-flagged
for v0.2. Tighter pinning lands as the corpus grows.
