I have all the context needed. Now I'll launch all five review agents in parallel with the full diff and file contents.

★ Insight ───────────────────────────────────── Before delegating to specialized agents, it's worth noting this PR is a classic dead code elimination pattern. The key invariant being removed (useConnectorContextFromElectronSettings always false) was verified through git history (FHIR-2040), making this safe to delete. The challenge in reviewing these is ensuring no subtle runtime path depended on the removed branch — especially around serialized/persisted settings. ─────────────────────────────────────────────────

Let me also verify the current error-flow in obtainConfiguration. The current shape is:

Summary

The test changes are appropriate and correctly reflect the dead-code removal. The deleted describe('when context usage from ddv settings is enabled') block tested a code path that has been removed, so its deletion is correct. The structural refactoring (flattening the nested describe) is sound and the tests remain accurate. There are no critical coverage gaps introduced by this PR, but there are two meaningful coverage ga …(truncated, 6564 more chars)

PR #7487 — Architecture Review

Scope: refactor(FHIR-2177): remove dead useConnectorContextFromElectronSettings flag

The dead-code removal itself is correct and well-executed.

★ Insight ───────────────────────────────────── All five specialized agents returned results. The most impactful finding is from the architecture reviewer: contextFromRequest is still typed as optional but the function now unconditionally throws if it's absent — the type system is lying to callers. The agents cross-validated several issues (duplicate fixture, stale Omit key, guard-clause pattern) giving high confidence. ─────────────────────────────────────────────────

Here is the full consolidated review in Conventional Comments format, organized by file and severity.

PR #7487 — refactor(FHIR-2177): remove dead useConnectorContextFromElectronSettings flag

Reviewer role: Senior Software Architect Files reviewed: 7 changed files (+35 / -81 lines) Overall signal: The dead-code removal is correct and well-scoped. Two issues need resolution before merge; the rest are non-blocking improvements.

src/modules/de/kbv-ti-connect/services/configuration-service/index.ts

issue (blocking): contextFromRequest is typed optional but is now unconditionally required

src/modules/de/kbv-ti-connect/services/configuration-service/index.ts
  obtainConfiguration signature

Before this PR the ?: ConnectorContextInput signature was honest: when useConnectorContextFromElectronSettings === true, contextFromRequest could legitimately be absent because context came from stored settings. That path is now gone. The current body unconditionally throws when contextFromRequest is undefined. The parameter's optionality is a type-system lie — every call site that omits it will fail at runtime with no compile-time warning.

// Before (misleading)
public static obtainConfiguration(
  traceId: string | number,
  contextFromRequest?: ConnectorContextInput,
)

// After (accurate)
public static obtainConfiguration(
  traceId: string | number,
  contextFromRequest: ConnectorContextInput,
)

Making it required will surface any callers that omit it (e.g. in gematik-idp-authentication/services/index.ts and gematik-e-rezept/services/index.ts per architecture grep results). Those call sites need to supply their context or the feature is broken — and TypeScript should tell them so, not a runtime error.

suggestion (non-blocking): Replace if/else with a guard clause now that there is only one happy path

src/modules/de/kbv-ti-connect/services/configuration-service/index.ts
  lines ~75–97 (the contextFromRequest if/else block)

After making contextFromRequest required (see above), the else branch becomes dead code entirely. Even before that, inverting to a guard clause makes contextToUse a const and flattens the happy path:

// Current
if (contextFromRequest) {
  contextToUse = this.normalizeRequestContext(contextFromRequest)
} else {
  kbvTiConnectLogger.error(...)
  throw new Error(...)
}

// Suggested guard clause
if (!contextFromRequest) {
  kbvTiConnectLogger.error(...)
  throw new Error(i18n.t('ti_connect.error_messages.missing_connector_context'))
}
const contextToUse = this.normalizeRequestContext(contextFromRequest)

This also groups both throw paths at the top of the function, making it obvious that the first !settings guard is missing the kbvTiConnectLogger.error call that the second one has (a pre-existing inconsistency worth a follow-up).

thought: normalizeRequestContext handles PascalCase and camelCase inputs but there is no comment explaining why

src/modules/de/kbv-ti-connect/services/configuration-service/index.ts
  lines ~44–60 (normalizeRequestContext)

The dual-casing branch ('MandantId' in contextFromRequest vs. contextFromRequest.mandantId) silently accepts two structurally different inputs. From grepping call sites, all production callers appear to pass PascalCase. If the camelCase branch was introduced for a specific operation (e.g. VerifyDocument from FHIR-1925), a single-line comment at the function would prevent future developers from quietly removing it or being confused by the as ConnectorContextCamelCase assertion. If neither case is in use, it's a candidate for a follow-up removal.

src/modules/de/kbv-ti-connect/services/types.ts

issue (non-blocking): UserEditableTiConnectSetting exclusion list contains a stale key

src/modules/de/kbv-ti-connect/services/types.ts
  UserEditableTiConnectSetting  Omit exclusion union

'eventSubscriptions' is in the Omit<TiConnectSettings, ...> exclusion list but is not a key of TiConnectSettings. Omit<T, K> where K ∉ keyof T is a silent no-op in TypeScript — the key is neither excluded nor flagged as an error. This is the same class of dead-exclusion that this PR correctly cleaned up for useConnectorContextFromElectronSettings. Remove 'eventSubscriptions' from the union; this PR is the natural place for that cleanup.

suggestion (non-blocking): Consider inverting UserEditableTiConnectSetting from an exclusion (Omit) to an allowlist (Pick)

The current Omit-based pattern encodes: "everything in TiConnectSettings is user-editable by default, unless listed here." For a security-sensitive surface (connector credentials, certificate fingerprints), the safer default is deny-by-default. A new sensitive field added to TiConnectSettings without updating the exclusion list silently becomes user-editable. A Pick-based allowlist forces explicit opt-in.

// Current (exclusion / opt-out)
type UserEditableTiConnectSetting = Exclude<keyof TiConnectSettings,
  'cert' | 'privateKey' | 'keyStorePath' | 'serviceEndpoints' | 'vsd'
> | 'modeOnlineCheck'

// Suggested (inclusion / opt-in)
type UserEditableTiConnectSetting = Pick<TiConnectSettings,
  | 'mandantId' | 'workplaceId' | 'userId' | 'clientSystemId'
  | 'serverCertificateFingerprint' | 'serverCertificate'
  | 'isCertificatesVerificationEnabled'
  // add intentionally; new fields are non-editable by default
> | 'modeOnlineCheck'

This is a broader architectural change — flag it for a separate ticket if not addressed here.

nitpick (non-blocking): Add a compile-time guard to catch future stale exclusion keys

// Ensures each exclusion key actually exists on TiConnectSettings at compile time
type _AssertExcludes = Record<
  'serviceEndpoints' | 'vsd' | 'cert' | 'privateKey' | 'keyStorePath',
  keyof TiConnectSettings
>

A single-line type assertion like this turns silent no-ops into compile errors when a field is removed from TiConnectSettings without updating the exclusion list.

thought: mandantId, clientSystemId, workplaceId, userId now only serve isTiContextLocal()

After removing the useConnectorContextFromElectronSettings branch, ConfigurationService no longer reads these four fields from settings. Their sole remaining consumer is isTiContextLocal() in ti-connect-settings.ts, which is called from module.ts to gate auto-connect at startup. The comment in module.ts already marks that check as broken ("this check would work only if connector context is local but that is not the case"). These fields are therefore kept alive by a known-broken check. This is out of scope for this PR, but a follow-up ticket to remove isTiContextLocal() and the four persisted fields would complete the cleanup started here.

The electron-store for ti_connect persists TiConnectSettings to disk.
