- Around line 560-562: Update moveMacRowScope to transfer the old owner’s
mac_route_removals to the new scope before deleting the old paired_macs row,
preserving tombstones through the ON DELETE CASCADE. Add a regression test
covering removal, scope claim, and registry refresh to verify the tombstone
remains after the endpoint is reinserted.
In
`@Packages/iOS/CmuxMobileShell/Sources/CmuxMobileShell/MobileShellComposite`+RouteRemoval.swift:
- Around line 35-37: Update the route-removal flow around
removeRouteIfAuthorized to match the current route by ID or, when IDs differ, by
route kind and endpoint before calculating routes. Use that matched route for
the precheck so refreshes with a replacement ID still allow
removeRouteIfAuthorized to perform its endpoint fallback and tombstone write.

#10437 made the automatic method strict — no cross-method fallback — and that also dropped the one route a pre-Iroh pairing has: the exact raw Tailscale endpoint its device-local migration grant names. #11890 documented that this route must survive and taught the connect-time policy gate to keep it, but the reconnect route gate ahead of that gate still filtered it away, so the route never reached it. Pass the pairing's migration grant to storedReconnectRoutes for the automatic method. It applies only when the pairing advertises no authenticated route, so a pairing with an Iroh identity is unchanged and a pairing with no grant still fails closed, which legacyMacWithoutIrohFailsClosedInsteadOfSendingBearerOverTCP and rejectedIrohReconnectNeverDowngradesToRawTailscale both assert in the same release gate. This restores preIrohPairingContinuesOverItsExactTailscaleRouteAfterIOSUpgrade with no change to the test. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* Restore the Iroh version-skew gate after IROH v2 The Tailscale version-skew gate required six tests in IrohTailscaleVersionSkewMacGateTests, but main has had two since merge 5839d6e dropped four of them. Port the two Stable listener tests to the v2 runtime. The legacy compatibility listener is now the cmux/mobile/1 dialect on the v2 endpoint, gated by the same pairing opt-in, so the tests assert that the explicit and historical settings allow Iroh networking and keep that dialect reachable. Expose the endpoint ALPN list and the legacy-dialect accept check from MobileHostIrxRuntime so the tests exercise the same code the accept loop uses. Retire the legacy TCP authorization tests. #12326 removed the Mac TCP listener and legacyPrivateNetworkListener, and #12754 removed them again after a merge restored them. Set the gate's expected count to four and record why in the script. Fixes #13683 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Select Tailscale Only in the pre-Iroh upgrade gate test #10437 made the automatic method strict: a pairing without an Iroh identity no longer falls back to its raw Tailscale route, and legacyMacWithoutIrohFailsClosedInsteadOfSendingBearerOverTCP asserts that. preIrohPairingContinuesOverItsExactTailscaleRouteAfterIOSUpgrade still assumed the old fallback, so it has failed since 7c3093e. The failure was hidden because the gate's Mac step failed first. The test now selects Tailscale Only for the migrated Computer and keeps every assertion: the reconnect succeeds over Tailscale only, carrying the exact host and port from the migrated grant.

Fixes iOS Tailscale route deletion persistence so a removed route stays removed across refreshes and relaunches, and makes Tailscale Only dial the exact phone-authorized raw Tailscale route instead of an Iroh lane pinned to Tailscale addresses.
Written for commit 6e01f59. Summary will update on new commits.
