Apply a “configuration as a contract” standard: when behavior depends on environment/profile/feature flags (remote vs local, active management profile, accessibility mode, client/server timing), wire that configuration into all relevant code paths and keep its semantics consistent across layers.

Checklist

• Cover transitions, not just initial state: if a feature flag can change at runtime (e.g., local→remote), ensure existing watchers/listeners and previously constructed components are updated or torn down accordingly.
• Mirror configuration across sibling components: if an option (e.g., screenReaderMode) is required for a user-facing terminal, ensure equivalent terminal variants (e.g., agent/output terminals with independent constructors) receive the same option.
• Register every new config-dependent API endpoint: when profile scoping is implemented via prefixes/lists, add new endpoints to the correct scoping registry so requests get the active profile.
• Align client timeouts and docs with server caps: do not set client ceilings/timeout comments that contradict the server’s actual maximum behavior.

Example patterns

• Profile-scoped endpoint registration:

  // In api.ts / shared config
  PROFILE_SCOPED_PREFIXES.add('/api/messaging/weixin/onboarding')
  // so fetchJSON can append the active management profile
  

• Remote-aware watcher lifecycle (conceptual): on mode change, stop the local watcher and prevent reloading local disk plugins from existing callbacks.
• Consistent terminal options:

  // In both terminal constructors
  const termOptions = { /* ... */ screenReaderMode: true }
  

• Timeout semantics:

  // Ensure client timeout constants/comments reflect the server’s real cap
  export const PROFILES_REQUEST_TIMEOUT_MS = SERVER_CAP_MS // or remove misleading comments
