Flightline · Your Standard

Aligned.

Your standard, set by policy, tuned by how you operate. Not learned from your loans. Flightline pins itself to the institution’s program, applies it identically, and sharpens its calibration over time without ever training on customer data.

§ 01You set the tone

Your policy. Our execution.

Three configuration lanes let each institution pin the standard to its own policy: what gets evaluated, how findings classify, how aggressively they surface. The institution writes the rules. Flightline applies them identically, every file.

Lane 01 · Scope

What gets evaluated.

Which programs, products, and overlay sets apply. A Fannie DU-approved conventional file is not checked against FHA handbook rules it does not need. An FHA file is not held to the conventional DTI threshold.

Lane 02 · Severity

How findings classify.

Critical, High, Medium, Low, defined by your policy, not ours. A stale paystub can be a Medium at one institution and a Critical at another. Flightline applies whichever definition you chose, without drift.

Lane 03 · Tolerance

How aggressively findings surface.

Threshold bands on DTI, LTV, reserves, compensating factors. The rubric reads the numbers deterministically; the sensitivity is tuned to your overlay. Raise the bar or lower it. The review will still land in the same place every time.

You keep the pen on policy. We guarantee the pen is applied identically.
§ 02Alignment over time

The system keeps learning how you operate.

The rubric is not static. Flightline adapts continuously, two ways. To how your team operates, how senior reviewers dispose of findings, which lanes your overlay treats more conservatively, where your practice runs sharper than the default. And to the shape of your portfolio, since an institution that specializes in self-employed, VA, or manufactured-home files does not need to be reviewed the same way as one that does not. The review sharpens against the work you actually do.

§ 03The data boundary

Aligned to your program. Not trained on your loans.

Flightline aligns to the shape of your QC program. It does not learn from your customers. The signal that tunes the rubric is structural, not content. The data that stays inside your tenant stays inside your tenant.

Feeds alignment
  • Configuration changes your team makes.
  • Reviewer decisions on findings, by category.
  • Override and adjudication counts, by lane.
  • Surfaced-vs-accepted ratios, aggregated.
Never leaves your tenant
  • Borrower PII and any 1003 field.
  • Document content, evidence text, extracted facts.
  • Any loan-record field, at any stage of review.
  • Any data used to train, fine-tune, or prompt-seed a model. No cross-tenant training, ever.
The standard is yours. The data is yours. The alignment happens in the gap between.
§ 04Pinned to the review date

The standard, sealed in time.

Every finding cites the selling guide, FHA handbook, VA circular, or federal regulation as published on the review date. Not the version current when the file is reopened two audits later. Every update is in the rubric before its effective date, with documented runway.

A file reviewed on 2025-02-14 cites the selling guide as published on 2025-02-14. Years later, the same review can be re-run against the same text and return the same finding.

An aligned standard is the only kind a fair-lending review can defend.

Inconsistent application of overlays across protected classes is precedent-setting risk. A portfolio reviewed against a single, aligned, versioned, sealed standard produces the documented decision-making fair-lending monitoring requires, without a separate analytics effort. Inconsistency across files, vendors, or reviewers is the exposure. Alignment closes it.
