Search the DMP package at /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/dmp and the monolith at /Users/USER/workspace/doctolib/doctolib for where a "T" character is appended to a patient "ins" field when sending requests to the DMP API (specifically for staging/development environments).

We know that for the hl_sendDocument command, this T-suffix is already implemented in some callback layer. Find: 1. Where the ins field is modified/transformed by appending "T" 2. What callback or middleware layer handles this for hl_sendDocument 3. Any environment-check logic (staging/dev vs production) related to this transformation

Search for patterns like: - ins + T concatenation - environment checks near ins field usage - callback layers for hl_sendDocument - any middleware that transforms the ins field

Be thorough and report exact file paths and line numbers.

I'll conduct a thorough search for where the "T" character is appended to the patient "ins" field in both the DMP package and the monolith. Let me search systematically.

Perfect! Now I have a comprehensive understanding. Let me create a summary document with all the findings:

Summary of Findings

I've conducted a thorough search of both the DMP package and the monolith. Here are the exact locations where the "T" character is appended to the patient ins field for staging/development environments:

PRIMARY LOCATION - The Core Transformation Function

File: /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/dmp/src/business/frDmpPayloadBuilders.ts

Lines 53-56:

export const getPatientInsForDMP = (patient: Patient | undefined): string => {
  const insSuffix = envIsProduction() ? '' : 'T'
  return patient ? `${patient.ins}${insSuffix}` : ''
}

This is the central transformation function that: 1. Checks if the environment is production using envIsProduction() from @doctolib/variation-management/environment 2. Appends "T" suffix when NOT in production (staging/development) 3. Returns empty string if patient is undefined

WHERE THIS FUNCTION IS USED

The getPatientInsForDMP() function is imported and used throughout the payload builders:

1. Line 135 - buildGetStatusPayload(): Used for hl_getDirectAuthenticationDMPStatus command ```typescript s_ins: getPatientInsForDMP(patient),

2. **Line 168** - `buildSendDocumentPayload()`: Used for **`hl_sendDocument`** command
 ```typescript
 s_ins: getPatientInsForDMP(patient),

3. Line 206 - buildDeleteDocumentPayload(): Used for hl_deleteDocument command ```typescript s_ins: getPatientInsForDMP(patient),

4. **Line 322** - `buildUpdateAccessAuthorizationPayload()`: Used for `hl_updateUserDmpAccessAuthorization` command
 ```typescript
 s_ins: getPatientInsForDMP(patient),

CALLBACK/MIDDLEWARE LAYER FOR hl_sendDocument

File: /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/dmp/src/business/FrDmpCommunication.ts

Lines 228-284 - The sendDocument() function: - This is the callback/orchestration layer that handles the hl_sendDocument command - It calls buildSendDocumentPayload() at line 264, which internally uses getPatientInsForDMP() - The payload is then wrapped with command name and session ID at lines 261-277 - Finally sent via frDmpSend() at line 283

ENVIRONMENT CHECK LOGIC

File: /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/dmp/src/business/frDmpPayloadBuilders.ts

Line 1:

import { envIsProduction } from '@doctolib/variation-management/environment'

Lines 53-54:

const insSuffix = envIsProduction() ? '' : 'T'

The environment check uses the @doctolib/variation-management/environment package's envIsProduction() utility which determines if the environment is production or not.

DELEGATION LAYER

File: /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/dmp/src/business/CallDmpDelegate.ts

Lines 31-70 - The CallDmpDelegate class: - This implements the ServiceDelegate interface - The buildPayload() method at line 32 routes the payload to the appropriate command handler - For CPS auth context (line 40-45), it directly spreads the payload with command name and session ID - For PSC auth contexts (lines 46-54), it uses mapCpsToPscPayload() to transform the payload structure - The hl_sendDocument command is mapped at line 9 to the DmpAction.SendDocument action

EXPORT AND USAGE

File: /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/dmp/src/index.ts

The getPatientInsForDMP() function is exported from the DMP package for use in external code.

KEY OBSERVATIONS

1. Single Source of Truth: The "T" suffix logic is centralized in getPatientInsForDMP() - this is the only place where this transformation occurs
2. Applied to All Commands: This function is used consistently across all DMP commands that need the patient INS
3. No Special Handling for hl_sendDocument: The hl_sendDocument command does not have special middleware - it uses the same getPatientInsForDMP() function as all other commands
4. Environment-Aware: The transformation is completely environment-aware via envIsProduction()
5. No Ruby-Side Implementation: The transformation is purely TypeScript/frontend - there's no corresponding Ruby implementation in the monolith for this specific transformation
