You are a Claude-Mem, a specialized observer tool for creating searchable memory FOR FUTURE SESSIONS.

CRITICAL: Record what was LEARNED/BUILT/FIXED/DEPLOYED/CONFIGURED, not what you (the observer) are doing.

You do not have access to tools. All information you need is provided in <observed_from_primary_session> messages. Create observations from what you observe - no investigation needed.

<observed_from_primary_session> <user_request>grill-me #Context and role You are a Senior Full stack developer at Doctolib and must create an implementation plan for the JIRA task https://doctolib.atlassian.net/browse/FHIR-1904, according with Doctolib Software Development guidelines and checking the development best practices like YGNI, DRY, SRP and SOLID.

There is no previous knowledge where the flags below are related in the code, and where exactly the related GDT code is in the codebase. - support_medical_device (global feature switch) - support_medical_device (organization feature switch)

Instructions

Investigate where the GDT code is in the monolith codebase and its relationship with the feature switches.

If necessary checkout the code, do it in a separate worktree, in one of the worktree directories by creating a branch with the prefix fhir-1904_ updated with the latest master branch.

Summarize the investigation by writing the details on a html file at @/Users/USER/Library/CloudStorage/<REDACTED>/My Drive/ai-artifacts/duty/FHIR-1904/discovery.html. Create the directory structure if necessary.

After finishing the investigation, create a implementation plan at @/Users/USER/Library/CloudStorage/<REDACTED>/My Drive/ai-artifacts/duty/FHIR-1904/implementation-plan.html

Your job is to monitor a different Claude Code session happening RIGHT NOW, with the goal of creating observations and progress summaries as the work is being done LIVE by the user. You are NOT the one doing the work - you are ONLY observing and recording what is being built, fixed, deployed, or configured in the other session.

SPATIAL AWARENESS: Tool executions include the working directory (tool_cwd) to help you understand: - Which repository/project is being worked on - Where files are located relative to the project root - How to match requested paths to actual execution paths

WHAT TO RECORD

Focus on durable technical signal: - What the system NOW DOES differently (new capabilities) - What shipped to users/production (features, fixes, configs, docs) - Changes in technical domains (auth, data, UI, infra, DevOps, docs) - Concrete debugging or investigative findings from logs, traces, queue state, database rows, and code-path inspection

Use verbs like: implemented, fixed, deployed, configured, migrated, optimized, added, refactored, discovered, confirmed, traced

✅ GOOD EXAMPLES (describes what was built or learned): - "Authentication now supports OAuth2 with PKCE flow" - "Deployment pipeline runs canary releases with auto-rollback" - "Database indexes optimized for common query patterns" - "Observation queue for claude-mem session timed out waiting for an agent pool slot" - "Fallback processing abandoned pending messages after Gemini and OpenRouter returned 404"

❌ BAD EXAMPLES (describes observation process - DO NOT DO THIS): - "Analyzed authentication implementation and stored findings" - "Tracked deployment steps and logged outcomes" - "Monitored database performance and recorded metrics"

WHEN TO SKIP

Skip routine operations: - Empty status checks - Package installations with no errors - Simple file listings with no …(truncated, 3199 more chars)

The ticket describes two identically-named feature switches (one global, one organization-level) that were used to gate GDT functionality. The ticket indicates the flags need either removal or migration strategy. Key requirements include: verifying whether the organization-level switch is redundant, investigating how to replace feature flag control with cohort-based assignment, and checking implementation approach with stakeholder Egon. The feature is currently live in production across France and parts of Germany, requiring careful refactoring.</narrative> <concepts> <concept>why-it-exists</concept> <concept>what-changed</concept> <concept>problem-solution</concept> </concepts> <files_read> </files_read> <files_modified> </files_modified> </observation>

Features are defined in YAML and loaded once, cached, and accessed through auto-generated methods. The model supports multiple feature types: per-country flags that store state per country code, cohort-based flags for context-aware targeting, probabilistic factor-based rollouts, and numeric value configurations. For per-country features like support_medical_device, a country-keyed hash stores individual country enable/disable states. The system integrates with Slack to notify team owners when features are toggled, and tracks expiration dates to alert on obsolete features.

The session is ongoing - you may receive more requests and tool executions after this summary. Write "next_steps" as the current trajectory of work (what's actively being worked on or coming up next), not as post-session future work. Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.

Claude's Full Response to User: I now have a thorough picture of the ticket and codebase. Let me start the interview.

★ Insight ───────────────────────────────────── - EquipmentConfiguration::Api.feature_enabled_for? implements a two-level OR gate: country-level (ApplicationPreference.support_medical_device_enabled_for_country?) OR org-level (account.feature_enabled_for_organizations?) - The per_country: true flag in config/feature_switches.yml means the global switch is actually keyed per country, not truly global - The migrate-feature-switch-to-cohort skill exists in this project — this task is likely a perfect candidate for it ─────────────────────────────────────────────────

Question 1 of N — Core intent

The ticket says "remove" the feature flags. But the feature is live to all of France and some practices in Germany. That means you can't simply delete the code — something must replace the gate.

Three options I see: - (A) Cohorts — migrate both country and org enablement to Doctolib's cohort system (the migrate-feature-switch-to-cohort skill exists for this) - (B) Always-on — remove the flag and make the feature unconditionally available (risky without understanding the full audience) - (C) Hybrid — keep country-level enablement as hardcoded logic, remove the organization switch

The ticket says "ideally we would love to have this not tied to this feature flag, but use some kinds of cohorts" and also says "please double check with Egon".

My recommendation: (A) Cohorts — it preserves the current audience precisely and follows the Doctolib migration path.

Which direction are you leaning, and have you already spoken to Egon about this?

<summary> <request>Investigate JIRA ticket FHIR-1904: Remove support_medical_device feature flags and determine how to migrate GDT (medical device configuration) functionality from feature-flag-based gating to a sustainable access control model</request>

<investigated> Complete codebase exploration of the support_medical_device feature switch implementation:

**Feature Switch Definitions:**
- Global: config/feature_switches.yml (per_country=true, expires 2026-05-31, team=FIRE)
- Organization-level: lib/data/organization/feature_switches.yml (same expiration date, team=FIRE)

**GDT Implementation:**
- Equipment configuration engine (engines/equipment_configuration) owns domain logic
- MedicalDevice and MedicalDeviceConfiguration models for device storage
- GDT examinations controller serving exam type configuration
- Electron-based UI integration for patient file/consultation views

**Feature Flag Integration:**
- Two-level OR gate: ApplicationPreference.support_medical_device_enabled_for_country?(country) OR account.feature_enabled_for_organizations?('support_medical_device')
- Frontend React hook useShowMedicalDeviceExamButton checks both levels
- GdtExportPolicy delegates entirely to feature flag (TODO comment notes incomplete implementation)

**Scope of Feature:**
- Live to entire France and some practices in Germany (production traffic)
- Requires organization admin + EHR subscription
- Electron workstation-specific

</investigated>

<learned> - The feature is NOT truly global despite "per_country: true" — it's a per-country switch stored as a Hash in ApplicationPreference - Both feature switches expire simultaneously on 2026-05-31, confirming the JIRA statement about coordinated expiration and alert spam - GdtExportPolicy has explicit TODO comment stating "Actual implementation not done yet" — currently sole access control is the feature flag - Account.feature_enabled_for_organizations? checks BOTH managed_organizations AND agenda organizations via PostgreSQL array operators - Organization::FeatureSwitch is a FrozenRecord (YAML-backed, not database) with dynamic method generation (SUPPORT_MEDICAL_DEVICE becomes a method) - Three viable migration paths: (A) Cohort-based targeting, (B) Always-on, (C) Hardcoded country logic + remove org switch - Ticket explicitly states "ideally we would love to have this not tied to this feature flag, but use some kinds of cohorts" and mentions checking with Egon </learned>

<completed> Investigation phase only — no code changes yet. Comprehensive discovery completed documenting: - 50+ files related to GDT and support_medical_device - Feature switch architecture and two-level gating mechanism - Complete data model and API flow - Test coverage and validation patterns - Frontend integration points </completed>

<next_steps> The assistant is currently asking the primary user (Question 1 of N) to clarify the intended migration approach: - Has the user (or Egon) decided between Cohort-based migration vs Always-on vs Hybrid approach? - Which direction is preferred given the JIRA ticket's stated preference for cohorts? - Once direction is confirmed, implementation plan will be created and documented </next_steps>

<notes> Critical findings for implementation planning: - The feature is production-live and has real users — any migration must preserve existing audience precisely - The dual expiration dates (global and org both 2026-05-31) suggest these were added together and should be removed together - @doctolib/xdt-toolkit provides GDT schema support (versions 6302, 6310, 6311) - No hardcoded country restrictions exist in code — all gating is via feature switches - The "organization feature switch" mentioned in ticket may be redundant if country-level flag handles global rollout, but this needs confirmation - A migrate-feature-switch-to-cohort skill exists in the project and is likely the intended approach </notes> </summary>

PROGRESS SUMMARY CHECKPOINT

Claude's Full Response to User: Good. Always-on it is. Next question.

Question 2 — Scope of "always-on"

Currently the feature is enabled for: - All of France (via the country-level global switch) - Some German practices (via the organization-level switch, specifically EHR DE users)

If we go always-on and simply delete the flag checks, the feature becomes available to every organization in every country — Italy, Spain, etc.

Two sub-options: - (B1) Truly global — remove all gates, feature is available everywhere - (B2) Hardcode the current audience — replace the flag check with an explicit country allowlist (country.in?(['FR', 'DE'])) so the blast radius stays the same, just without a feature flag

The ticket says "this is only enabled in France and in Germany (if you are an EHR DE user)" — which suggests the team didn't intend to expand beyond that.

My recommendation: (B2) Hardcode the current audience — safer, preserves today's behavior, and you can always expand countries later via a simple code change rather than a flag rollback.

Do you want to expand to all countries, or keep FR + DE only?

Thank you, this summary will be very useful for keeping track of our progress!

<summary> <request>Decision checkpoint on FHIR-1904 always-on migration approach: Determine whether to make GDT feature globally available (all countries) or restrict to current audience (France + Germany only) via hardcoded allowlist</request>

<investigated> Prior investigation established complete GDT architecture and feature switch implementation. Current question focuses on migration strategy scope:

**Current audience (from feature flags):**
- France: entire country via global per_country flag
- Germany: EHR DE users via organization-level flag
- No other countries have flag enabled

**Migration options under discussion:**
- B1 (Truly Global): Remove all feature flag checks, make GDT available everywhere
- B2 (Hardcoded Audience): Replace feature flag checks with explicit country allowlist (FR, DE only)

</investigated>

<learned> - Going "always-on" means removing the feature flag entirely (not just extending expiration) - Removing all flag checks without guards would inadvertently expand feature to Italy, Spain, and all other countries - The ticket's phrasing ("only enabled in France and in Germany") suggests intentional geographic scoping, not accidental limitation - Hardcoding country allowlist preserves blast radius while eliminating feature flag infrastructure - Hardcoded allowlist enables future expansion via code review + deployment (no feature flag management needed) </learned>

<completed> - User confirmed always-on approach (option B) is the chosen direction - No code changes yet; decision framework established </completed>

<next_steps> Awaiting user confirmation on scope: - If B1 (truly global): expand GDT to all countries, implement unconditional availability - If B2 (hardcoded FR+DE): replace feature flag checks with country.in?(['FR', 'DE']) guard, maintain current audience

Once scope is confirmed, will proceed to implementation plan including:
- Identify all locations where feature flag checks must be replaced
- Determine if organization-level flag logic needs to be preserved or removed
- Plan for backward compatibility and gradual rollout

</next_steps>

<notes> Key architectural implications: - Global flag (ApplicationPreference.support_medical_device_enabled_for_country?) must be replaced with hardcoded logic or removed entirely - Organization-level flag (account.feature_enabled_for_organizations?) must be removed or converted to a permanent organization attribute - GdtExportPolicy's TODO comment about incomplete implementation may require addressing during migration - Frontend hook (useShowMedicalDeviceExamButton) currently checks both country and org flags — will need update to reflect new gating - Test coverage will need updates to reflect hardcoded country logic instead of feature flag mocking </notes> </summary>

PROGRESS SUMMARY CHECKPOINT

Claude's Full Response to User: Noted — globally available to all. Next.

Question 3 — Organization-level switch

The ticket says "I'm pretty sure we don't need the organisation feature switch anymore, but please double check."

The org-level switch (lib/data/organization/feature_switches.yml) allows individual organizations to have support_medical_device enabled even when the country-level switch is off. The API check is:

# engines/equipment_configuration/app/public/equipment_configuration/api.rb
ApplicationPreference.support_medical_device_enabled_for_country?(country) ||
  account.feature_enabled_for_organizations?(Organization::FeatureSwitch.SUPPORT_MEDICAL_DEVICE.id)

If we go always-on (B1), both of these checks become irrelevant. The org-level switch was only useful as an override for countries where the country switch was off (e.g. Germany). With no gates at all, the org switch has zero purpose.

My recommendation: Remove both — the global switch from config/feature_switches.yml and the org switch from lib/data/organization/feature_switches.yml. The feature_enabled_for? method in the public API becomes either deleted or hardcoded to true.

Should we remove the org-level switch too, or keep it as a kill switch in case something goes wrong?

Thank you, this summary will be very useful for keeping track of our progress!

Current analysis focuses on the OR logic in `EquipmentConfiguration::Api.feature_enabled_for?`:
```ruby
ApplicationPreference.support_medical_device_enabled_for_country?(country) ||
  account.feature_enabled_for_organizations?(Organization::FeatureSwitch.SUPPORT_MEDICAL_DEVICE.id)

</investigated>

<learned>
  - User has confirmed B1 (truly globally available) as the chosen direction
  - With B1 (always-on), both feature switches become architecturally obsolete — neither gate has any effect
  - Organization-level switch's original purpose was to override/enable the feature when country-level switch was off
  - In always-on scenario, organization switch provides no functional value but could serve as emergency kill switch if needed
  - Removing both switches means deleting from two YAML files and removing/hardcoding the `feature_enabled_for?` method
</learned>

<completed>
  - Decision confirmed: always-on/globally available approach (B1)
  - Scope confirmed: make feature available to all countries (not limited to FR+DE)
</completed>

<next_steps>
  Awaiting user decision on kill-switch question:
  - Option 1: Remove both switches entirely (cleaner, no dead code)
  - Option 2: Remove global switch, keep organization switch as emergency kill switch (safer fallback)

  Once decided, implementation will proceed with:
  - Removal of feature flag definitions from YAML files
  - Replacement or deletion of feature check logic in EquipmentConfiguration::Api
  - Updates to all callsites (GdtExportPolicy, useShowMedicalDeviceExamButton hook, tests)
  - Verification that feature is unconditionally available
</next_steps>

<notes>
  Trade-offs to consider:
  - **Full removal**: Eliminates technical debt, simplifies codebase, but removes emergency kill switch capability
  - **Keep as kill switch**: Preserves ability to disable feature globally without code deployment, but leaves dead/misleading code paths during normal operation
  - The organization switch has no impact on current behavior in B1 scenario (feature always enabled) but provides production safety valve
  - Both switches expire 2026-05-31 anyway, suggesting they were intended as temporary gates
  - Test infrastructure extensively mocks these switches — migrations will require significant test updates

PROGRESS SUMMARY CHECKPOINT
===========================
Write progress notes of what was done, what was learned, and what's next. This is a checkpoint to capture progress so far. The session is ongoing - you may receive more requests and tool executions after this summary. Write "next_steps" as the current trajectory of work (what's actively being worked on or coming up next), not as post-session future work. Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.

Claude's Full Response to User:
Important clarification needed here.

**Question 4 — Kill switch semantics**

The current org switch is **opt-in**: organizations in `features_enabled` array **get** the feature. As a kill switch you'd want the opposite — a way to **disable** the feature for a specific org.

There are two different interpretations of "keep as kill switch":

- **(K1) Global kill switch only** — keep the global `support_medical_device` in `config/feature_switches.yml` but default it to `true`. If production explodes, flip it to `false` and it shuts off everywhere
- **(K2) Per-org kill switch** — introduce a new mechanism (e.g. a `disable_support_medical_device` org switch, or invert the existing one) so you can silently disable for a specific organization without touching all others

The current org switch can't directly serve as a kill switch without inverting its semantics, which would be a breaking change to the existing data (German orgs that currently have it enabled would suddenly be *disabled*).

**My recommendation: (K1) Keep the global switch defaulting to `true`** — simpler, uses existing infrastructure, no data migration. The org switch gets removed since it no longer has a purpose.

**Which kill switch model do you want: global (K1) or per-org (K2)?**

<request>Clarification on kill-switch semantics for FHIR-1904 always-on migration: Determine whether to implement global kill switch (K1) or per-organization kill switch (K2) for emergency feature disable</request>

<investigated>
  Analysis of existing organization-level switch semantics:
  - Current `support_medical_device` in `lib/data/organization/feature_switches.yml` is opt-in: orgs in `features_enabled` array get the feature
  - Account#feature_enabled_for_organizations? checks if feature exists in org's features_enabled array
  - As kill switch, would need opt-out semantics: disable for specific orgs, not enable
  - Inverting current switch would break existing data (German orgs with feature enabled would become disabled)

  Two kill-switch models discussed:
  - K1 (Global): Keep global switch in config/feature_switches.yml, default to true, flip to false for emergency
  - K2 (Per-org): Create new disable mechanism or invert existing switch (requires data migration)
</investigated>

<learned>
  - Kill switch requires opposite semantics from feature enablement: opt-out vs opt-in
  - Current organization switch cannot directly convert to kill switch without inverting logic (breaking change)
  - Global switch in config/feature_switches.yml can serve as kill switch more naturally (set default: true, flip to false in emergency)
  - K1 approach reuses existing ApplicationPreference infrastructure and feature flag system
  - K2 would require designing new per-org disable mechanism and migrating existing organization data
</learned>

<completed>
  - Decisions confirmed: always-on approach (B1), globally available (all countries)
  - Architecture decision pending: kill switch model selection (K1 vs K2)
</completed>

<next_steps>
  Awaiting user decision on kill-switch implementation:
  - If K1 (Global kill switch): Keep global `support_medical_device` in config/feature_switches.yml with default: true, remove organization switch entirely
  - If K2 (Per-org kill switch): Design new organization-level disable mechanism or invert existing switch (requires data migration planning)

  Once decided, implementation will proceed with:
  - Defining final feature flag configuration (or complete removal if no kill switch)
  - Updating EquipmentConfiguration::Api.feature_enabled_for? logic
  - Removing/updating all feature flag checks across codebase
  - Planning test migration strategy
</next_steps>

<notes>
  Critical semantic distinction:
  - **Opt-in** (current org switch): "feature is off by default, enabled for specific orgs"
  - **Opt-out** (kill switch): "feature is on by default, disabled for specific orgs/globally"
  - These are opposite mental models and have opposite data implications

  K1 advantages: Simple, reuses existing infrastructure, no data migration
  K2 advantages: Granular control per organization, but complex implementation and breaking change to existing data

  If K1 selected, the feature check becomes:
  ```ruby
  ApplicationPreference.support_medical_device_enabled? # simple boolean check

Organization-level switch becomes completely removed.

PROGRESS SUMMARY CHECKPOINT

Claude's Full Response to User: Good. K1 — global switch stays, defaults to true, org switch removed. Next question.

Question 5 — EquipmentConfiguration::Api.feature_enabled_for? fate

This public API method is the single choke point that all GDT authorization flows through:

# engines/equipment_configuration/app/public/equipment_configuration/api.rb
def feature_enabled_for?(account)
  ApplicationPreference.support_medical_device_enabled_for_country?(main_admin_organization&.country) ||
    account.feature_enabled_for_organizations?(Organization::FeatureSwitch.SUPPORT_MEDICAL_DEVICE.id)
end

With K1, the global switch defaults true for all countries. Two options:

(M1) Delete the method — remove all call sites too. Callers (GdtExportPolicy, GdtExaminationsPolicy) no longer check it; they just authorize based on role alone
(M2) Simplify but keep the method — rewrite it to just ApplicationPreference.support_medical_device_enabled? so the global kill switch still flows through it. Callers stay unchanged

My recommendation: (M2) Keep the method, simplify its body — it's a clean public API boundary. If you later need to add logic (per-country re-gating, cohort migration), the call sites don't change. Deleting it saves a few lines but loses the indirection that makes the kill switch meaningful.

Delete the method entirely (M1) or keep it simplified (M2)?

<summary> <request>Decision on EquipmentConfiguration::Api.feature_enabled_for? method during FHIR-1904 refactoring: Should the method be deleted entirely (M1) or kept as a simplified API boundary (M2)?</request>

<investigated> Analysis of the feature_enabled_for? method: - Current implementation in engines/equipment_configuration/app/public/equipment_configuration/api.rb - Serves as single authorization choke point for all GDT flows - Currently checks: country-level flag OR organization-level flag - Called by: GdtExportPolicy, GdtExaminationsPolicy, possibly frontend feature detection - With K1 decision (global switch defaults true), the complex OR logic simplifies to just the global switch check

Two refactoring options:
- M1 (Delete): Remove method and update all call sites to check feature directly
- M2 (Simplify): Keep method as API boundary, simplify body to `ApplicationPreference.support_medical_device_enabled?`

</investigated>

<learned> - The method acts as indirection layer between authorization policies and feature flag infrastructure - M1 removes lines of code but loses the abstraction boundary - M2 preserves the public API contract so future changes (per-country re-gating, cohort migration) don't cascade to callers - With K1, the method body reduces from complex OR logic to a single flag check - Keeping the method provides extensibility point for future authorization logic without changing call sites </learned>

<completed> - Decisions confirmed: always-on (B1), globally available, K1 kill switch model (global switch defaults true, org switch removed) - Technical architecture refined: global switch will remain in config/feature_switches.yml with default: true </completed>

<next_steps> Awaiting user decision on method fate: - If M1 (Delete): Remove feature_enabled_for? method, update all call sites to use ApplicationPreference.support_medical_device_enabled? directly - If M2 (Simplify): Keep method, rewrite body to single ApplicationPreference check

Once decided, implementation will proceed with:
- Identifying all call sites of feature_enabled_for? (GdtExportPolicy, GdtExaminationsPolicy, potentially others)
- Removing or simplifying the method
- Updating organization feature switch references
- Updating test mocks and stubs
- Removing country-level per-country flag logic

</next_steps>

<notes> API boundary trade-off: - M1 (Delete): Saves code, but makes future authorization logic changes cascade to all call sites - M2 (Simplify): Adds one indirection layer, but provides stable public API for potential future features

If M2 selected, the method becomes:
```ruby
def feature_enabled_for?(account)
  ApplicationPreference.support_medical_device_enabled?
end

  Note: account parameter becomes unused but could be removed in a separate cleanup

  Extensibility consideration: If per-country re-gating or cohort migration happens later, M2 allows logic to change without updating GdtExportPolicy, GdtExaminationsPolicy, and other callers.

**Question 6 — Frontend feature check**

The frontend also gates the medical device exam button independently:

```typescript
// packages/@doctolib/equipment_configuration/src/utils/useShowMedicalDeviceExamButton.ts
isFeatureEnabled('support_medical_device', 'any-organization-of-account', account) ||
isFeatureEnabled('support_medical_device', 'global', account)

With K1 (global switch defaults to true), the 'global' check will pass for everyone. But the 'any-organization-of-account' check references the org-level switch we're removing. Two options:

(F1) Remove both checks — delete the feature gate entirely from the hook, keeping only the isElectron guard (the natural hardware constraint — no Electron, no button)
(F2) Keep only the global check — isFeatureEnabled('support_medical_device', 'global', account) so the global kill switch also propagates to the UI

My recommendation: (F2) Keep the global check — it mirrors M2 on the backend; the kill switch (K1) flows end-to-end through both server and client without extra coordination.

Remove frontend gate entirely (F1) or keep the global check (F2)?

<summary> <request>Decision on frontend medical device exam button feature gating during FHIR-1904 refactoring: Should the frontend feature checks be removed entirely (F1) or simplified to only the global kill switch (F2)?</request>

<investigated> Analysis of frontend feature gating in useShowMedicalDeviceExamButton hook: - Current implementation checks two feature flags: - isFeatureEnabled('support_medical_device', 'any-organization-of-account', account) — org-level flag - isFeatureEnabled('support_medical_device', 'global', account) — global flag - Uses OR logic: button shows if either flag enabled - Also guards with isElectron (hardware constraint) - Located in packages/@doctolib/equipment_configuration/src/utils/useShowMedicalDeviceExamButton.ts

Two refactoring options:
- F1 (Remove): Delete all feature checks, rely only on Electron guard
- F2 (Simplify): Keep only the global check to propagate K1 kill switch to frontend

</investigated>

<learned> - Frontend feature checking mirrors backend authorization structure - With K1 (global defaults true), the global check always passes for users; org check now references non-existent switch - Electron guard is a natural hardware/environment constraint that will remain meaningful - F2 approach maintains consistency with backend M2 decision (keep simplified method) - Kill switch effectiveness depends on end-to-end propagation (backend AND frontend) </learned>

<completed> - Decisions confirmed: B1 (always-on), K1 (global kill switch), M2 recommendation accepted - Backend authorization pattern established: simplified feature_enabled_for? method, global switch as kill switch </completed>

<next_steps> Awaiting user decision on frontend gating: - If F1 (Remove gates): Delete both isFeatureEnabled checks, keep only isElectron guard - If F2 (Keep global): Replace dual check with single global check to mirror backend kill switch

Once decided, implementation will proceed with:
- Updating useShowMedicalDeviceExamButton hook
- Removing organization feature switch references from frontend
- Ensuring kill switch (if F2) flows through both server and client layers
- Updating frontend feature flag mocking in tests
- Coordinating with backend removal of org switch from config

</next_steps>

<notes> End-to-end kill switch consideration: - F1 (Remove): Simpler frontend code, but backend kill switch doesn't prevent button rendering — users see button, backend rejects action - F2 (Keep global): More consistent with backend (M2), kill switch prevents both button render AND backend authorization — better UX on kill

F2 approach means:
```typescript
const showButton = isElectron && 
  isFeatureEnabled('support_medical_device', 'global', account) &&
  satisfiesMedicalDeviceRequirements(...)


  The global flag becoming default: true means this always evaluates to true in normal operation, but supports emergency disable (K1 kill switch) by flipping to false.

**Question 7 — Feature switch expiry**

The ticket explicitly says: *"Extend the time on the feature flag so it doesn't spam our public channel."*

The current expiry in `config/feature_switches.yml`:
```yaml
expire_at: 2026-05-31  # 12 days from today

When a feature switch expires, it sends noise to a public Slack/monitoring channel. Since we're keeping the global switch as a K1 kill switch, we need to either extend or remove the expiry.

Two options: - (E1) Remove expire_at entirely — the switch has no expiry, it's permanent infrastructure - (E2) Extend by N months — push it out (e.g. 2026-12-31 or 2027-06-30) to buy time while the full removal is planned

My recommendation: (E1) Remove expire_at — since this switch is now a permanent kill switch by design (not a temporary rollout gate), an expiry date doesn't make semantic sense anymore.

Remove the expiry entirely (E1) or extend it (E2)?

Thank you, this summary will be very useful for keeping track of our progress!

<summary> <request>Decision on feature switch expiration handling during FHIR-1904 refactoring: Should the expire_at field be removed entirely (E1) or extended to buy time (E2)?</request>

<investigated> Feature switch expiration analysis: - Current expire_at: 2026-05-31 in config/feature_switches.yml - Expires in 12 days from current date (2026-05-19) - JIRA ticket explicitly mentions: "Extend the time on the feature flag so it doesn't spam our public channel" - Expiry triggers alerts to public Slack/monitoring channels - Original purpose: temporary rollout gate (expires to remind team to remove it) - New purpose with K1: permanent kill switch infrastructure

Two options:
- E1 (Remove): Delete expire_at entirely, switch becomes permanent infrastructure
- E2 (Extend): Push expiry date out (e.g., 2026-12-31, 2027-06-30) to defer the alert spam

</investigated>

<learned> - Feature switch expiry was designed for temporary gates (roll out gradually, expire to remind removal) - With K1 redesign, the switch transforms from temporary rollout gate to permanent kill switch - Permanent infrastructure doesn't need an expiry date by definition - E1 removes the semantic mismatch: kill switches aren't temporary features - E2 acknowledges the original temporary nature but extends timeline </learned>

<completed> - Decisions confirmed: B1 (always-on), K1 (global kill switch), M2 (simplify method), F2 (keep global check) - All prior architectural decisions finalized and accepted </completed>

<next_steps> Awaiting user decision on expiration strategy: - If E1 (Remove expiry): Delete expire_at field entirely, mark switch as permanent infrastructure - If E2 (Extend expiry): Push expire_at to future date (e.g., 2027-06-30), solving immediate alert spam

Once decided, implementation will proceed with:
- Updating config/feature_switches.yml support_medical_device entry
- Removing organization switch from lib/data/organization/feature_switches.yml (already confirmed)
- Coordinating with infrastructure/monitoring team if removing expiry (alerts may be configured expecting expiry dates)
- Creating comprehensive implementation plan documenting all changes

</next_steps>

<notes> Semantic transformation: - Original purpose: "This feature is experimental, auto-expire to force team to decide" - New purpose: "This feature is core infrastructure, kill switch for emergency disable"

E1 advantages: 
- Matches semantic intent (permanent infrastructure)
- Removes alert spam permanently without extensions
- Signals to team that switch is intentional, not deferred cleanup

E2 advantages:
- Solves immediate alert spam (12-day deadline)
- Preserves reminder mechanism for future full removal
- Safer if team wants to reconsider K1 approach later

The JIRA ticket's explicit request was "Extend the time...so it doesn't spam" — E2 directly addresses that concern, while E1 eliminates the spam source entirely.

Claude's Full Response to User: Good. Next question.

Question 8 — per_country: true attribute

The global switch currently has per_country: true, which means the flag is keyed independently per country. The auto-generated method is:

ApplicationPreference.support_medical_device_enabled_for_country?(country)

For K1 (a single global kill switch), you'd want one toggle that kills everything at once. Two options:

(P1) Remove per_country: true — becomes a simple global boolean. The simplified feature_enabled_for? becomes ApplicationPreference.support_medical_device_enabled? with no country argument. One flip kills all countries simultaneously
(P2) Keep per_country: true — retains per-country granularity. feature_enabled_for? keeps the country lookup from the account's organization. You can kill France without killing Germany

My recommendation: (P1) Remove per_country: true — aligns with K1's "one toggle, global effect" semantics. If you need per-country control in the future, that's a separate feature.

Remove per_country: true (P1) or keep it (P2)?

<summary> <request>Decision on per-country feature switch granularity during FHIR-1904 refactoring: Should per_country: true be removed for single global kill switch (P1) or retained for per-country control (P2)?</request>

<investigated> Analysis of per_country feature switch attribute: - Current: per_country: true in config/feature_switches.yml - Generates method: ApplicationPreference.support_medical_device_enabled_for_country?(country) - Stores value as Hash keyed by country ISO codes: { 'FR' => true, 'DE' => true, ... } - Enables independent country-level toggles (France can be off while Germany is on) - With K1 design, the switch is intended as single global kill switch

Two options:
- P1 (Remove): Becomes simple boolean, one toggle affects all countries
- P2 (Keep): Retains per-country granularity, allows selective country disable

</investigated>

<learned> - per_country: true adds complexity but enables fine-grained control - K1 global kill switch semantic expects a single toggle with uniform effect - P1 aligns with stated K1 design: "one flip kills everything" - P2 sacrifices simplicity but preserves operational flexibility (can disable in one country during incident) - Removing per_country requires simplifying feature_enabled_for? method further (no country lookup) </learned>

<completed> - Decisions confirmed: B1 (always-on), K1 (global kill switch), M2 (simplify method), F2 (keep global check), E1 (remove expiry) all accepted - Design pattern solidifying: single global boolean kill switch with uniform emergency disable </completed>

<next_steps> Awaiting user decision on per-country handling: - If P1 (Remove per_country): Becomes simple boolean feature switch, EquipmentConfiguration::Api uses only ApplicationPreference.support_medical_device_enabled? with no country parameter - If P2 (Keep per_country): Retains country parameter and per-country Hash structure, feature_enabled_for? continues to lookup country from organization

Once decided, implementation will proceed with:
- Updating feature switch definition in config/feature_switches.yml
- Finalizing EquipmentConfiguration::Api.feature_enabled_for? signature
- Removing ApplicationPreference dynamic method generation for country-specific checks (if P1)
- Removing organization feature switch entirely
- Creating comprehensive implementation specification

</next_steps>

<notes> Kill switch granularity trade-off: - P1 (Remove per_country): - Semantically cleaner (one toggle = one effect) - Easier to understand and debug - Emergency disable affects all users simultaneously (no regional variance) - Future per-country control requires separate mechanism

- **P2 (Keep per_country)**:
  - Preserves operational flexibility (regional incidents)
  - More complex to test and verify
  - Kill switch has per-country granularity (can isolate problems)
  - Adds complexity to feature_enabled_for? method unnecessarily

With E1 (remove expiry) likely chosen, the switch becomes permanent infrastructure. P1 aligns better with that intent — permanent global infrastructure typically uses global controls, not per-region fine-grained toggles.

The JIRA ticket mentions "this is only enabled in France and in Germany" — that geographic constraint came from feature flag rollout, not from per_country attribute. With B1 (always-on globally available), that geographic distinction becomes moot, supporting P1 approach.
