Build kit · companion to the Atlas

NachoLOS — the loan manufacturing system

A point-of-sale system persuades. A loan origination system manufactures. This is the build kit for the back office: the file enters at one end and leaves insured, delivered and purchased — with every station owned, gated and stamped. Built from Sharon LittleJohn's operational notes, the existing codebase, and the POS Atlas it has to join.

What makes this different

Four sources, one document

Sharon's raw operational notes (11,129 words, verbatim — including Maddie's dictated frustrations), the blueprint built from them, a source-level review of the existing NachoLOS codebase, and the POS Atlas. Where they disagree on how the shop runs, Sharon's notes win — she is describing a licensed operation that exists.

Compliance as controls, not categories

The blueprint lists check names inherited from a competitor's published coverage summary. This maps every rule to the control that satisfies it — and says out loud that coverage copied from marketing copy is not a compliance control.

The QC module that was one line

Sharon supplied pages of agency QC requirements — FHA's sampling split, VA's 13-point review, Fannie's prefunding selection. The blueprint carried a single catalog row. Rebuilt here as nine features, including reviewer independence the system can actually enforce.

The seam, written down

Ownership table, push contract, event contract, stage mapping, adapter interface — so the developer merging the two volumes doesn't invent the boundary. Including the one conflict three documents disagree on: who sends disclosures.

An honest mobile position

Not "fully responsive." Named lists of what belongs on a phone and what must never move there. Where a screen is desktop-only it shows a useful read-only view and says why — rather than a broken miniature nobody uses.

Ten omissions, catalogued

Ten things in Sharon's own notes that the blueprint dropped — the brokered channel (10–15% of volume), the QC program, TX A(4), the veteran property-tax exemption, PACER, representative-score logic, pre-AUS validations, her closing checklist, the KPI framework, credit supplements. Each verified by direct search, each now has a home.

Read the honest parts first

This kit is deliberately loud about what it does not know. The regulatory citations need compliance-counsel confirmation before build. The competitive comparison is being rebuilt on real evidence rather than impressions. The Excel formulas behind the worksheet library have not been handed over yet — not a blocker for the framework, required before that feature ships. A specification that hides its uncertainty is harder to build from than one that maps it.

The decision that outranks the rest

D-02 · Who owns disclosure generation and delivery. Sharon says all disclosures are sent in the LOS. The blueprint says the LO sends from the POS. The POS Atlas assumed POS-side delivery. Three documents, three answers — and whoever owns delivery owns the three-business-day deadline. This has to be settled by a person, not by whichever developer writes the code first.
