# File835Builder

`File835Builder` renders the outbound 835 remittance-advice EDI file (version constant `"1.3"`) for an e-billing batch, as part of the EOB output chain in operation OP-DOM-12: it names the clearinghouse file, retrieves the clearinghouse and the "EOB distributed" bill status, and builds the full 835 segment structure via `EdiBuildSegments` — envelope segments (ISA, GS, ST, BPR, TRN, REF, DTM, N1, N3, N4, PER), the loop-1000 payee segments, per-EOB LX/CLP/NM1/REF/DTM/AMT segments, per-service SVC/DTM/CAS/REF/AMT/LQ segments, and closing SE/GE/IEA segments — that communicates payment and adjustment information back to the clearinghouse. Its segment-by-segment construction was not traced line by line in the source analysis, so the class's behaviour is documented from its single entry point's signature and surrounding calls*.

## Purpose
- Produces the complete outbound 835 remittance-advice `IEdiFile` for a batch, given the e-billing query provider, claim query provider, user profile, and Guidewire financial-data API client needed to resolve payment details.
- Marks bills as EOB-distributed as part of building the file, using the "EOB distributed" bill status resolved from `IEbillingQueryProvider`*.

## Context
- Namespace: `SAIF.Domain.Claims.Ebilling`
- Assembly/package: `SAIF.Domain` (`Domain/SAIF.Domain/SAIF.Domain.csproj`, .NET Framework 4.6.2 class library)

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| Version | `public const string Version = "1.3"` | Identifies the 835-remittance-file version this class implements. |
| CreateFile | `public static IEdiFile CreateFile(IEbillingQueryProvider ebillingQueryProvider, IClaimQueryProvider claimQueryProvider, IUserProfileService userProfileService, Model.Claims.Ebilling.Batch batch, bool isProductionRun, ILogWriter controlLog, ILogWriter segmentLog, ICCClaimApiService cCClaimApiService, IFinancialDataApiClient financialDataApiClient)` | Builds the outbound 835 file for the batch: assigns a clearinghouse file name if none is set, resolves the clearinghouse and EOB-distributed bill status, and writes the remittance-advice segment structure, logging progress to the supplied control/segment log writers*. |

## Behavioral notes
- When the batch does not already have a `ClearinghouseFileName`, `CreateFile` assigns one via `NameBuilder.GetFileName("835", isProductionRun)` before building the file.
- The detailed per-segment remittance content (adjustments, service lines, remittance advice codes) was not traced line by line from the source; readers needing exact 835 segment content should consult the source file directly**.
