Search the codebase for: 1. The feature switch nhr_document_list in config/feature_switches.yml or any YAML config files 2. How NHR_DOCUMENT_LIST_ENABLED is defined as a dl_constants / frontend constant 3. How cohort-based feature switches are exposed to the frontend as dl_constants

Key paths to check: - config/feature_switches.yml - Any file defining NHR_DOCUMENT_LIST_ENABLED - How cohort feature switches get translated into dl_constants JS constants

Return: the full definition of the nhr_document_list feature switch, the NHR_DOCUMENT_LIST_ENABLED constant definition, and any middleware or helper that maps feature switches to dl_constants.

Good! Now let me look at the feature_switches.yml around line 5707 and read the ApplicationPreference model:

Perfect! Now let me check how the feature switch gets converted to a frontend constant. Let me read more of the FrontendConstantsHelper to see the full picture:

Tool results:

Let me search for how feature switches are transformed into constants in the frontend:

Excellent! Now I have all the information I need. Let me compile the findings:

Summary of Findings

1. Feature Switch Definition: nhr_document_list

File: /Users/USER/workspace/doctolib/doctolib/config/feature_switches.yml

Full Definition (lines 5707-5717):

nhr_document_list:
  cohort_types:
    - account
  default: false
  details: Enables the NHR (National Health Records / DMP) document list modal for
    healthcare professionals. Part of DMP 3.1a certification.
  expire_at: 2027-06-01
  message: NHR document list — DMP 3.1a feature rollout
  send_to_front: true
  team: FIRE
  value_in_test: false

2. Frontend Constant: NHR_DOCUMENT_LIST_ENABLED

There is no explicit constant definition named NHR_DOCUMENT_LIST_ENABLED in the codebase. Instead, it is dynamically generated at runtime by the frontend constants helper.

The constant is created on-the-fly by the evaluate_feature_switch_pair method in the FrontendConstantsHelper, which transforms the YAML feature name nhr_document_list into the constant NHR_DOCUMENT_LIST_ENABLED.

3. How Cohort-Based Feature Switches Are Exposed to Frontend as dl_constants

File: /Users/USER/workspace/doctolib/doctolib/app/helpers/frontend_constants_helper.rb

Key Flow:

1. Controller (/Users/USER/workspace/doctolib/doctolib/app/controllers/doctor_app/constants_controller.rb): - Calls build_constants method from FrontendConstantsHelper - Returns JSON that becomes window.dl_constants on the frontend

2. Helper Method: build_constants (lines 120-129): ```ruby def build_constants CONSTANTS.merge( { built_with_account: assumed_or_current_account&.id }, engines_frontend_constants, feature_switches_sent_to_front, # <-- Feature switches injected here dynamic_constants, country_features, deprecated_associated_account_fs, ) end

3. **Feature Switch Extraction**: `feature_switches_sent_to_front` (lines 133-140):
 ```ruby
 def feature_switches_sent_to_front
   cohort_context = build_cohort_context
   ApplicationPreference::FEATURES
     .filter { |_feature_name, feature_attributes| feature_attributes['send_to_front'] == true }
     .to_h do |feature_name, feature_attributes|
       evaluate_feature_switch_pair(feature_name, feature_attributes, cohort_context)
     end
 end

• Filters features where send_to_front: true (which includes nhr_document_list)
• Calls evaluate_feature_switch_pair for each feature

4. Feature-to-Constant Transformation: evaluate_feature_switch_pair (lines 219-250): ```ruby def evaluate_feature_switch_pair(feature_name, feature_attributes, cohort_context) per_country = feature_attributes['per_country'] == true per_speciality = feature_attributes['per_speciality'] == true per_ssid = feature_attributes['per_ssid'] == true

   return handle_value_feature(feature_name, per_country) if feature_name.ends_with?('_value')

   bare_feature_name = feature_name.to_s.sub(/_factor\Z/, '') feature_key = "#{bare_feature_name.upcase}_ENABLED" # <-- Creates NHR_DOCUMENT_LIST_ENABLED

   if feature_name.ends_with?('_factor') # Factor handling else [ feature_key, if per_country ApplicationPreference.send("#{bare_feature_name}_enabled_for_country?", country) else ApplicationPreference.send("#{bare_feature_name}_enabled?", context: cohort_context) # <-- For cohort features end, ] end end

5. **Cohort Context Evaluation**: `build_cohort_context` (lines 282-296):
 ```ruby
 def build_cohort_context
   resources = []
   if assumed_or_current_account.present? && desktop_pro_or_mobile_pro_domain?
     resources = [assumed_or_current_account, *assumed_or_current_account.all_current_organizations.select(:id)]
   end

   resolved_cohorts = ApplicationPreferences::ContextResolution.resolved_cohorts_from_resources(resources)
   resolved_cohorts.evaluation_context(skip_cohort_type_requirements: true)
 end

• For nhr_document_list (which has cohort_types: [account]), this builds a cohort context containing the current account
• Passes this context to ApplicationPreference.send("nhr_document_list_enabled?", context: cohort_context)

6. Cohort Resolution: /Users/USER/workspace/doctolib/doctolib/lib/application_preferences/context_resolution.rb - Maps Account/Organization resources to Cohorts::Identity objects - Groups identities by resource type (e.g., :account, :organization) - Returns cohort membership data that determines if the feature is enabled
