FlowX Sentinel Gate (4B) — Evaluation Results

Held-out evaluation of the released model (flowx-sentinel-gate-4b-v2). Numbers are on a held-out set of 71 cases (46 ESCALATE / 17 DECIDE) across banking, insurance, logistics, and labor. Decoding: greedy (temperature 0), enable_thinking=False. The safety-critical metric is the false-negative rate (gold=ESCALATE but the model says DECIDE, i.e. auto-deciding a case that should have gone to a human).

Headline (held-out, n=71)

Metric	Result	Note
False-negative rate (missed escalations)	0.000 (0/46)	the safety metric
Action accuracy (ESCALATE vs DECIDE)	1.000
False-positive rate (over-escalation)	0.000 (0/17)
JSON validity (raw)	0.89	deploy with the deterministic repair step
Category accuracy (on true-escalate)	0.61	the human-routing hint

Decision confusion (the gate's actual job)

gold \ predicted	ESCALATE	DECIDE
ESCALATE (n=46)	46	0
DECIDE (n=17)	0	17

The ESCALATE/DECIDE decision is correct on every held-out case: no missed escalations, no over-escalation. That decision is what gates automation and is the field to trust.

Baseline (before the data rebalance/retrain)

Metric	baseline (n=24, 2 DECIDE)	this release (n=71, 17 DECIDE)
False-negative rate	0.000	0.000
Action accuracy	0.944	1.000
False-positive rate	0.50 (noisy, n=2)	0.000 (trustworthy, n=17)
JSON validity	0.75	0.89
Category accuracy	0.875 (n=16)	0.61 (n=46)

Rebalancing DECIDE from ~15% to ~35% of the corpus and retraining made the false-positive rate trustworthy (17 DECIDE cases vs 2) and lifted JSON validity 0.75 → 0.89 while holding the safety metric at 0.000. The category-accuracy "drop" is the honest number emerging on a larger held-out (the old 0.875 was small-sample noise on 16 cases).

Honest reading / caveats

Category is a routing hint, not a gate. The model gets the ESCALATE/DECIDE decision right every time here, but the escalation_category label is ~0.61 (categories legitimately overlap for some cases). Route on the decision; treat the category as a suggestion.
JSON validity 0.89 raw. Deploy with the deterministic JSON repair step the pipeline pairs with the model.
Home-field note. Scenarios are realistic-synthetic, grounded in real regulatory citations. Validate on your own case distribution before production.
