New pack

SAR narrative quality

Cadre pack · Redliner

Drafts and checks a narrative while treating unsupported facts as a failed evaluation.

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

Drafts the FinCEN SAR narrative from an investigation packet, then checks each revision against a completeness rubric; any fact absent from the packet fails the evaluation.

Decision logic
  1. 01Drafts the narrative section of a SAR from an investigation packet, then checks revisions against a configured completeness rubric within a defined review limit.
  2. 02Grounding is a non-negotiable evaluation rule: any amount or name the packet does not establish fails the case rather than being introduced into a regulatory draft.
  3. 03Gaps the packet cannot close are recorded as unresolved items and written around honestly, not papered over.
  4. 04States observations, not conclusions of law — the pattern of deposits under a reporting threshold, not an accusation of laundering.
  5. 05Stops at the rubric bar or the configured review limit, whichever comes first; the narrative is not padded to chase a score.
Must not
Invent missing evidence or act outside the permitted outcomes.
Human owner
Unresolved source gaps and filing approval
Evidence retained
Structured outcome, observed path, and the source evidence used.

Twelve cash deposits each between 8,200 and 9,600 USD, all below the 10,000 USD CTR reporting threshold, Deposits clustered across three branches over nineteen days, Deposit volume inconsistent with the stated import-wholesale profile and prior account history, Funds aggregated then wired out within 48 hours of deposit to a single overseas beneficiary

Packet · Typology assessment
Cash structuring (smurfing) to evade the 10,000 USD CTR threshold, followed by rapid layering via outbound international wire. Consistent with placement-then-layering money laundering.
Packet · Recommendation
SAR
Packet · Recommendation rationale
Pattern of sub-threshold cash deposits aggregated and wired offshore is a textbook structuring-and-layering typology with no legitimate business explanation in the file.

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.

  • Full packet

    structuring plus layering. The draft should cover the who, what, when, where, why, and how from the supplied record, then be checked against the configured completeness rubric.

    Case key

    rich-structuring-complete
  • Medium packet

    a BEC redirection. The narrative should cover the five Ws and the how from the facts actually present, no further.

    Case key

    medium-bec-most-facts

Boundary and misuse cases

Plausible inputs that could produce a costly or overconfident decision.

  • Sparse packet

    dates, counterparties, and a clear typology are missing. The pack must not invent them — any amount or name absent from the packet fails the case, and the gaps remain unresolved.

Operating fit

Workflow placement and validation

Operating pattern

Draft, check, revise

Separate drafting from checking and stop when the work meets clear requirements—or when the agreed review limit is reached.

Decision sequence and workflow placement

  2. 02Check named requirements
  3. 03Return specific gaps
  4. 04Revise

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
