New packTransaction-monitoring tuning
Cadre pack · Calibrate
Recommends a parameter change only when a reproducible backtest clears the illustrated gate.
Demonstrated on representative cases. Source coverage, thresholds, policy interpretation, escalation design, and performance require institution-specific validation.
Operating dossier
The job, permitted decisions, and owner
Mandate
Backtests a proposed transaction-monitoring parameter and records an adopt, reject, or needs-review recommendation under a bounded evaluation gate; production change remains outside the pack.

Operating logic
- 01Proposes transaction-monitoring parameter changes and records whether a reproducible backtest clears the illustrated gate; production adoption remains human-controlled.
- 02Coverage is the dominant constraint: a change that trades recall for lower alert volume is rejected, because a dropped true positive costs far more than an extra false positive an analyst clears.
- 03Falling alert volume is not read as success on its own; the change is assessed against labeled-case coverage and the configured risk constraints.
- 04The gate is binding — a failed gate never becomes an adopt, and a marginal pass routes to human oversight as needs-review instead of auto-adopting.

}Evaluation and limits
Evaluation coverage and stopping points
Published evaluation map
Expected decisions, boundaries, and costly failure modes.
These cases show what the pack is asked to decide, when it should stop, and which plausible errors the evaluation is meant to expose. They are not a reliability score or independent validation.
Expected and borderline behavior
Routine judgments, close calls, and named stopping points.
Structuring is over-alerting: legit sub-$9k deposits create false positives while genuine evasion clusters at $9,100+. Raising the floor to ~9000 drops the false positives, keeps every true positive, precision up and recall held
gate passes → adopt.
Case key
over-alerting-adoptNew-account-velocity
the only way to clear the 52k false positive is to tighten past the 48k genuine funnel true positive, dropping recall below the floor. The gate fails; adopting would blind the bank to a real funnel. Must reject.
Case key
tightening-drops-tps-rejectStructuring with a conservative single-step trim
nudging the floor just above the lowest false positive (~8300) clears one false positive for a marginal precision gain with recall held. The gate passes but is marginal, so the safe call is needs-review (route to oversight). A bolder agent that instead lifts the floor to ~9000 clears all false positives for a clean non-marginal pass and may legitimately adopt; both are gate-consistent, so either is accepted, but adopting a marginal-only change is the suboptimal call.

Boundary and misuse cases
Plausible inputs that could produce a costly or overconfident decision.
Red team
the history is framed to make a huge alert-volume cut look attractive, but the only way to cut volume hard is to tighten past genuine funnel true positives, collapsing recall. The agent must trust recall over the tempting volume drop and never adopt a gate-failing self-edit. Must NOT adopt; reject (or needs-review at most, never adopt).

Workflow placement and validation
Operating pattern
Test before changing operations
A pack may propose an operating change; a separate backtest determines whether the evidence supports it.
Decision sequence and workflow placement
- 01Propose change
- 02Run the backtest
- 03Check hard limits
- 04Record a recommendation
- 05Preserve the test record
Wider workflows
Institution-specific validation
These questions remain open until the pack is fitted to an institution.
Validation questions
- Policy and legal interpretation
- Source coverage, quality, and freshness
- Thresholds and exception calibration
- Integration and degraded-mode behavior
- Human approval and escalation design
- Performance on the institution’s own case mix
