Saved environments on mobile got messy after re-pairing:

  • Pairing a new server at a saved address left the old entry stuck on "does not match" next to the new one (#15802).
  • Pairing a second address after a login expired left the other routes on the dead login. Removing the new route then locked the environment out (#17014).
  • A T3 Connect environment kept the name it had when it was added, after the host was renamed (#15683).
  • A machine paired over LAN moved into the T3 Connect group when T3 Connect was added, and did not come back (#23367).

Fix

All of this is in the shared records layer (packages/client-runtime), so web and desktop get it too.

  • Same address, new server: after a pairing, other environments drop their route at that address. If it was their only route, they are removed. Only a real pairing does this, because the server has just confirmed its id. Editing a URL never removes another environment. SSH routes are left alone.
  • One login per environment: a new pairing writes its login to every address paired for that environment. Learned routes already borrow it. SSH and T3 Connect keep their own. An edit that reuses the saved login does not spread it. A login paired over HTTPS, loopback, or the tailnet is not copied to a plain HTTP LAN or public address, the same rule learned routes follow. Re-pairing an address saved under an older route id also drops the learned routes that borrow the old login.
  • Labels: T3 Connect and learned routes only hold a copy of the environment's label. Renaming or pairing an address now updates those copies, so a rename shows even when T3 Connect comes first. An environment saved only through T3 Connect takes its host's name on connect. A label you set on a paired address is kept.
  • Grouping: a machine with an address you paired stays in the local list and has T3 Connect as another route. This is shivamhwp's fix from #23382, unchanged.

#12012 (trash does nothing) did not reproduce. On an iOS 26.5 simulator, the confirm appears, and the removal is still in place after a relaunch. Maintainers found the same in the issue thread, so there is no change for it here.

Evidence

Proof: a failing test per bug in its existing test file, plus before/after on an iOS 26.5 simulator with two local servers. #23367 and #15683 need a T3 Connect account on the device, so they have test proof only.

#15802. Server A paired, then replaced by B at the same address. Before (main): two BeeBox rows, one stuck. After: B replaces A.

main: duplicate entry at the same address fix: before and after pairing at the same address

#17014. Pair over the tailnet IP, revoke that login, pair again over the MagicDNS name, remove the MagicDNS route, relaunch. Left (main): "did not accept this device". Right: still connected.

main vs fix after removing the newly paired route

#12012: the trash on a saved direct environment shows its confirm. I tested a connected environment; the maintainer check in the issue covered an offline one.

Remove from this device confirm

Notes

  • Two different machines at the same private IP and port on different networks: pairing one replaces the other, as #15802 asks. Asking first is UI work left as a follow-up.
  • Left to the connection thread from #17014: a timeout on one route hides another route's 401, and the server's expiry reason is not shown.

Fixes #15802 Fixes #17014 Fixes #15683 Refs #23367: the grouping cause is fixed and tested, but the exact off/on/off cycle needs a T3 Connect account to replay. Refs #12012

🟠 High platform/storageDocument.ts:163

When isNewLogin is true, this stores the fresh credential under every saved bearer route’s own connectionId, so an old http:// route is treated as having its own credential and sendsTokenInClear allows the token to be sent in cleartext. Preserve the credential’s transport provenance and enforce the restriction for paired routes as well.

Note

🤖 Claude Opus 5.5 responding on behalf of Theo

Fixed in 80ee0c4cea. A new pairing now copies its login only to paired routes that aren't plain HTTP on LAN or public, unless the pairing itself was over plain HTTP. This uses the same check as tokenAllowsPlainHttp, now shared as isPlainHttpRoute in routes.ts. Test: "a login paired over HTTPS is not copied to a plain HTTP LAN address" in storageDocument.test.ts. It fails on the previous commit.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This is a substantial shared connection-runtime change that synchronizes bearer credentials, changes plain-HTTP transport eligibility, and can remove stale routes across saved environments. Its authentication/security implications and cross-environment persistence side effects warrant human review.

You can add or adjust custom eligibility rules. Learn more.

Walkthrough

Connection summaries now distinguish relay-route presence from relay-managed status. Pairing updates route ownership, route learning applies host labels, and bearer registration propagates new credentials to eligible routes.

Changes: Connection routes and pairing

Layer / File(s)Summary
Route-aware connection summaries
packages/client-runtime/src/state/presentation.ts, packages/client-runtime/src/connection/routes.ts, apps/mobile/src/state/*, apps/mobile/src/features/connection/*, apps/mobile/src/features/home/*, apps/mobile/src/features/pull-requests/*, apps/mobile/src/features/showcase/*		Connection summaries report relay-route presence and prefer the saved bearer route URL. Mobile environment sections and removal prompts use relay-route presence. Tests and fixtures cover the updated summary behavior.
Pairing registration and route ownership
packages/client-runtime/src/connection/onboarding.ts, packages/client-runtime/src/connection/registry.ts, packages/client-runtime/src/connection/registry.test.ts		Pairing passes a paired-registration flag. The registry removes conflicting routes to the paired address from other environments and updates routes for the registered environment. Tests cover re-pairing, address edits, and route removal.
Learned routes and host labels
packages/client-runtime/src/connection/routes.ts, packages/client-runtime/src/connection/registry.ts, packages/client-runtime/src/connection/supervisor.ts, packages/client-runtime/src/connection/*test.ts		Route learning accepts missing reported endpoints and receives the host label. Registry and supervisor changes apply labels to learned routes and update eligible route labels.
Bearer credential updates
packages/client-runtime/src/platform/storageDocument.ts, packages/client-runtime/src/platform/storageDocument.test.ts, packages/client-runtime/src/connection/routes.ts		When a bearer token changes, registration assigns the credential to the registered connection and eligible non-learned bearer routes. Tests cover credential retention across route types and addresses.

  • Issue 15683: The PR updates eligible relay and learned-route labels from the host label, addressing stale saved labels for those routes.
  • Issue 23868: The PR propagates a new pairing credential to eligible bearer routes, but does not change the generic permission error or archived-thread action.

Pairing can leave a stale environment saved when it has multiple routes at the paired address. Remove every conflicting route before merging, or accept this narrow case for follow-up.

Explanation

The PR changes fall into three groups. (1) Registry, credential, route, and label code in packages/client-runtime. These directly implement #15802, #17014, and #15683. (2) Mobile grouping changes: environmentSections.ts (savedRelayEnvironmentIds, hasRelayRoute), useConnectionController.ts, presentation.ts (hasRelayRoute, displayUrl), remote-environment-registry removal prompt, and showcase rows. These implement the grouping fix the PR describes, referenced as Refs #23367. #23367 is not a linked issue here, so this is a scope note, not a mismatch. The PR body states the purpose of each group, and the summary shows matching tests. (3) Test files. These support the changes above. No change was found that is unrelated to the PR goals. Uncertainty: mobile UI hunks and the full diff were assessed from the summary, not from every line.

Full details: Linked Issues check

Explanation

Per issue:

[#15802] PASS. registry.ts register(..., { paired: true }) removes routes to the same address from other environments. The environment is removed when that route was its last one. Editing a URL does not trigger removal. Registry tests cover this path.

[#15683] PASS. routesWithHostLabel and routesWithCopiedLabel (routes.ts) update relay and learned-route label copies on connect and on rename or pairing. A paired-address label is kept. Optional discovery sync and infra/relay environment_label refresh are not in the PR. The issue lists these as optional.

[#17014] FAIL for the reported reproduction. In storageDocument.ts, registerConnectionInCatalog copies a new login to a non-learned bearer route only when pairedInClear || !inClear(route). A tailnet pairing (not plain HTTP) therefore does not update a paired plain HTTP LAN route. In the issue scenario (LAN pairing, then Tailscale pairing, then Tailscale route removed), the LAN route keeps the revoked login. The environment stays on a dead login, which the issue's Expected behavior forbids. The issue's Suggested direction 1 also requires LAN, Tailscale, and public routes to share the newest credential. Suggested items 2 to 5 (drop dead logins on 401, pass the server expiry reason, prefer 401 over timeout, show login status) are not implemented. The PR states that connection-thread work is left open.

Resolution

#17014: Make a new bearer login reach paired plain HTTP LAN routes of the same environment, or otherwise ensure that removing the newly paired route leaves a working login on the remaining direct routes. Update the owners rule in registerConnectionInCatalog (storageDocument.ts) and add a test for the sequence: LAN pairing, Tailscale pairing, remove Tailscale route. If the maintainers keep the plain-HTTP restriction, the issue must be narrowed to a stated scope and the LAN case documented as unfixed. Also state how revoked or expired logins stop being sent. This is the expected-behavior requirement, not an optional suggestion.

Full details: Description check

Explanation

The description explains the problem, the changes, and focused verification with test and simulator evidence. It links related issues, but it does not provide explicit maintainer approval of the direction and scope or explain why the changes qualify for an approval exemption. The required scope-and-approval information is missing.

Resolution

Add the maintainer approval comment or discussion that approves this direction and scope. If an approval is not required, explain why this is a small, focused fix of an obvious bug. Clarify how the linked issues fit one underlying problem and why the changes belong in the same pull request.

Remove all conflicting bearer routes at the paired address.

When another environment has multiple bearer routes at the paired address, cleanup removes only the first matching route. A learned route with a different credential can remain, so the stale environment stays saved with a competing route.

Note

Written by claude-opus-5-5 on behalf of eyeveil

We hit the bug this PR's register change fixes on a fork client and landed the same change there. One gap remains for clients that already have the stale routes saved: mergeLearnedRoutes keeps a learned @<old route id> route as long as the server still reports its address, so that address is never learned again and the route fails preflight about once a minute (Connection credential bearer:<env> is unavailable).

An 8-line follow-up drops a learned route whose borrowed route is no longer saved, so the address is learned again over the active route on the next connect: https://github.com/eyeveil/t3code/commit/9c5c6835422d05f02db5ce6a07c8060b9829e91a (branch eyeveil:fix/learned-route-cleanup, on main). Its test, "learns again an address whose borrowed token's route is gone", fails on main and passes with the change. Happy to open it as its own PR, or you can take it into this one.
