feat(ios): state connection method and live transport in diagnostics reports - #10310
Merged

Conversation
A transport report today only implies the connection method and carrier transport through whichever dial events survived the bounded ring; reading one still needs a Settings screenshot. Record the configured method (connectionMethodConfigured) at store construction and on every foreground so any report window states it, decode the existing connectionMethodPreferenceChanged value into the same readable method name, and record foregroundTransportSelected with the active route's transport on connect and on every route change, covering both state-then-route and route-then-state connect flows plus mid-connection promotions. Reports now carry lines like: App feature event (Operation: connectionMethodConfigured, Method: Tailscale Only) App feature event (Operation: foregroundTransportSelected, Transport: Iroh) en+ja catalog entries for the new method and field names.

📝 WalkthroughWalkthroughThe PR adds diagnostic events for configured connection methods and selected foreground transports. It adds localized presentation, records configured methods during app activity, records connected route changes, and adds tests for event values and ordering. ChangesConnection Method Diagnostics

- Around line 65-76: Replace the boolean-style ternary mappings in
recordConfiguredMethodDiagnostic() and connectionMethodPreferenceChanged with a
shared exhaustive typed conversion from MobileConnectionMethod to
DiagnosticConnectionMethod, following the existing
CmxAttachTransportKind-to-DiagnosticTransportKind pattern in
DiagnosticTaxonomy.swift. Ensure new enum cases require an explicit mapping and
preserve the current diagnostic values for existing cases.

…vely Review follow-up: replace the 0/1 ternaries with an exhaustive switch into DiagnosticConnectionMethod so a future third method becomes a compile error instead of silently reporting as Tailscale. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Reading a shared transport report currently requires a Settings screenshot to know whether the user selected Tailscale Only, and the carrier transport is only implied by whichever dial events survived the 4096-event ring. The field report that motivated this (a Tailscale Only user whose traffic rode Iroh relays, see #10294) needed both facts and had neither.
Three additions, no report-schema change:
connectionMethodConfiguredis recorded when the method store is constructed and on every app foreground, so any report window states the configured method even after the ring rolls past launch.MobileConnectionMethodStoreowns the recording; the composition root triggers the per-foreground refresh.foregroundTransportSelectedrecords the active route's transport on the connected transition and on every active-route change while connected, covering connect flows that pin the route before or after the state flip and mid-connection promotions.connectionMethodPreferenceChangedvalue now decodes to the same readable method name instead ofValue: 0/1.Reports now carry lines like:
en+ja entries added for the new method names and field label. Tests: presentation decoding (
describesConnectionMethodAndForegroundTransport), store recording at init/on demand, and shell recording on connect, route change, and the disconnected no-op. NoteDiagnosticEventPresentationTestshas pre-existing failures on main (decodesEveryStructuredPayloadIntoSemanticFields, superseded-session fields) unrelated to this change; the new test passes.🤖 Generated with Claude Code

States the configured connection method and the live foreground transport in iOS diagnostics so shared reports no longer depend on dial-event remnants or Settings screenshots. Previously, method/transport were implied; now reports include connectionMethodConfigured and foregroundTransportSelected with readable values, and connectionMethodPreferenceChanged decodes to the same method names.
MobileConnectionMethodStoreconstruction and on every app foreground (triggered fromios/cmux/AppCompositionRoot.swift); no schema change.CmuxMobileShell.MobileShellComposite, covering route-before-state, state-before-route, and mid-connection promotions.CMUXMobileCore.DiagnosticEventPresentationrenders Method and Transport fields; adds en/ja strings and theDiagnosticConnectionMethodenum inCMUXMobileCore.DiagnosticTaxonomy.MobileConnectionMethodtoDiagnosticConnectionMethodexhaustively (no 0/1 ternaries), preventing silent misreporting if a third method is added.DiagnosticEventPresentationTestsfailures remain unchanged.Written for commit 3f2b88f. Summary will update on new commits.
