Problem

After a successful OpenCode update, T3 Code keeps showing the old version when an instance's server URL points at OpenCode 2's background service. opencode upgrade replaces the binary on disk, but the running opencode serve --service keeps executing the old one, and that is the process T3 Code asks for its version. Observed on a real install: binary 2.2.5, service still 2.1.3 with /proc/<pid>/exe marked (deleted). The update then ends with "still detects an outdated provider version" until something else restarts the service.

Change

After an update, T3 Code now replaces the service the same way the OpenCode TUI's restart does, using the published @opencode/client/effect/service: Service.stop with pty: "handoff", then Service.ensure. That path hands persistent terminals to the new process. opencode service restart shuts them down first, and opencode service start does not replace a stale service, so neither CLI command fits.

• Only this install's service. Service.discover reads the local registration and contacts only its registered address. The configured URL is then compared locally: the same protocol and port, and either the same host or a wildcard listener with its own family's loopback. The local service's password is never sent to the configured URL.
• Only after an update, only for that instance. ProviderInstance.afterUpdate runs from refreshAfterUpdate for the selected instance, before the version is read back. Status checks never replace anything.
• Failures are visible. A failed replacement marks the instance as failed and the update as unverified, rather than reporting success. The error has a fixed message and keeps its cause, as docs/internals/effect-services.md requires.
• The service outlives T3 Code. It runs in its own AgentScope scope, so stopping T3 Code's systemd unit does not kill it, and without the ELECTRON_RUN_AS_NODE that T3 Desktop's backend sets. The stop and start can't be interrupted, so a dropped client can't leave no service running.
• One replacement per update. A version the probe can't match gets one replacement rather than a repeating kill loop.
• T3 Code reconnects to the new service. Every OpenCode instance drops its cached connection when an update starts, and the updated one again afterwards, so sessions and features that depend on the version, such as native goals, see the new one.
• Service settings are kept. Variables from the service's service.json are passed to the new process, as the CLI does.
• OpenCode 1.x is unchanged. It has no background service. The helper T3 Code starts for 1.x keeps the behavior chosen in fix(opencode): verify updates using the installed CLI version #18561, which fixed [Bug]: OpenCode update reports "still needs an update" after a successful upgrade because verification reads the running server version #13010.

Behavior to weigh:

• Replacing the service interrupts any turn running on it, the same as opening the TUI. The update is an explicit user action, and the 2.x adapter already reconciles after a server restart.
• If OpenCode was updated outside T3 Code, the old version keeps showing until the user presses Update. That repairs it, since opencode upgrade exits 0 when already current.
• These setups keep reporting the running server's old version and are not replaced: a localhost URL, this machine's LAN or tailnet address, and an independently launched opencode serve.
• Another instance on the same binary with its own service stays stale until Update is pressed on it.
• The replaced service runs with T3 Code's environment rather than the shell that started it. Variables it needs can be set with opencode service set env, and docs/user/providers-opencode.md now says so.
• On a failed replacement, the service's stderr can reach T3 Code's local log, as failed update command output already does.

Scope and approval

This relates to open issue #22869, the same symptom on a loopback URL, but does not fully fix it: that reproduction uses an independently launched opencode serve, which T3 Code does not own and this PR leaves alone. That issue has no triage labels, and I have no maintainer approval to link. This fix is focused but not trivially small, so it may need triage first under CONTRIBUTING.md.

Verification

Ran at 3fed040 in an isolated HOME/XDG_* sandbox with the real OpenCode binaries. The service was registered as http://0.0.0.0:49555, with a live persistent terminal and a session, and the binary upgraded from 2.1.3 to 2.2.5 underneath it:

before                     server 2.1.3 pid 1117882   pty running 1117924
http://192.0.2.10:49555    no-op, server 2.1.3
http://localhost:49555     no-op, server 2.1.3
http://[::1]:49555         no-op, server 2.1.3
http://127.0.0.1:49555     replaced in 484 ms
after                      server 2.2.5 pid 1118942   pty running 1117924   same session

• At 95c6ead, the last code change: the real 2.2.5 binary behind a wrapper whose --version printed 2.2.6, to force a mismatch, replaced from inside a transient KillMode=mixed user unit with ELECTRON_RUN_AS_NODE=1 and the real AgentScope layer. It took 468 ms with the same terminal PID and session. The PID was stable 3 seconds later, the service ran in its own scope without that variable, and it still answered after the unit was stopped.
• At the first commit, through the real OpenCodeDriver: snapshot.refresh reported 2.1.3, then afterUpdate, then 2.2.5. The second run was a no-op.
• For comparison, opencode service restart on the same setup destroyed the terminal (PtyNotFoundError).
• vp run check:changed passes. It includes a new test for replaceOutdatedService, which failed against the earlier URL matching, plus a hook-order assertion in ProviderRegistry.test.ts.

Not checked:

• Pressing Update in the UI end to end. No client code changed.
• A real T3 Desktop or t3 service install. Both were simulated by their environment and unit settings.
• A real 2.1.3 to 2.2.5 upgrade at the last code change, since the older version would no longer install in the sandbox.
• Windows. A shell shim that can't be spawned directly skips the replacement instead of stopping the service, but this has not been run there.

Independent model reviews ran up to fbee882, with bot reviews in between: five rounds with GPT-6.1 Sol via Codex and one with Claude Opus 5.5. The commit that fixes Opus's findings, 95c6ead, was reviewed only by CodeRabbit, since Sol had hit its usage limit and the developer chose not to wait. Codex's review of it failed on a usage limit. CodeRabbit's one finding there was a docs correction, fixed in the final commit, d9576a5. Decisions so far:

Source	Finding	Decision
Sol	A PATH in the service config could make a bare binary name fail after the old service stopped	Fixed: the executable is resolved first, and nothing stops if it can't be found
Sol	The hook ran for instances that weren't updated, so an unchanged binary could replace a newer service	Fixed differently: it runs only for the selected instance, rather than matching on the maintenance lock key
Sol	The config lookup ignored OPENCODE_CONFIG_DIR	Fixed
Macroscope	Service.incumbent sent the local service's password to the configured URL, which could be another machine	Fixed: replaced with Service.discover and a local URL match. Earlier Sol rounds missed this
CodeRabbit	A failed replacement was logged and hidden from the registry	Fixed
CodeRabbit, Sol	Raw failure text could reach logs	Fixed: the error carries only a fixed message
Sol, Codex	The URL match treated separate IPv4 and IPv6 listeners as one service	Fixed: localhost no longer matches, as listed above
CodeRabbit	http on port 80 could match https on 443, as both parse to an empty port	Fixed: protocols are compared
CodeRabbit	The replacement error dropped its cause	Fixed, reversing an earlier removal, since the repo's error conventions require it
CodeRabbit	The new test's fixture is POSIX-only	Fixed: skipped on Windows, as in driver.test.ts
Opus	The replacement inherited T3 Desktop's ELECTRON_RUN_AS_NODE	Fixed
Opus	The replacement ran in T3 Code's systemd unit, so stopping T3 Code killed it	Fixed: it runs in its own scope
Opus	An interrupt between stop and start could leave no service running	Fixed
Opus	A version the probe can't match caused a kill loop	Fixed: one replacement per update
Opus	The docs didn't mention the restart	Fixed
CodeRabbit	The docs implied any local address restarts the service	Fixed: they name the addresses that match
Sol (after merging main)	The cached connection kept the replaced service's old version	Fixed: forgotten after an update
Sol (after merging main)	A session reconnecting during the restart, or another instance on the same service, kept the old connection	Fixed: every instance forgets it when an update starts
CodeRabbit	Verify identity so localhost and other aliases match	Skipped: localhost could be either family, the settings placeholder uses 127.0.0.1, and an unmatched setup honestly reports the old version
CodeRabbit	A service still starting is skipped	Skipped: a brief window with an honest stale result, repaired by pressing Update again
Codex	Changing the binary path during an update runs the hook with the new binary	Rejected: it needs a settings change mid-update, and the service then runs the binary the user just configured, reported honestly

A council (Claude Opus 5.5 and GPT-6.1 Sol) and the developer agreed to remove a closeIfIdle change for the 1.x helper from this PR: it was a separate fix, unproven on a real 1.x binary, and would have reopened the decision in #18561.

After main was merged in, resolving conflicts in driver.ts and ProviderRegistry.test.ts, a review loop with GPT-6.1 Sol ran three rounds on c16df60. Round 1 confirmed the merge kept both sides' behavior and that mise-managed updates still work with the replacement; rounds 1 and 2 found the connection issues above. Round 3 found nothing material and ran 259 focused tests across seven files.

Walkthrough

The provider registry now runs an optional post-update effect for the selected instance. The OpenCode provider uses this effect to check for a matching registered service and, when applicable, replace it with a service using the installed binary.

Changes: OpenCode post-update refresh

Layer / File(s)	Summary
Provider post-update hook packages/provider-core/src/server/driver.ts, apps/server/src/provider/ProviderRegistry.ts, apps/server/src/provider/ProviderRegistry.test.ts	ProviderInstance adds an optional afterUpdate effect. After cache invalidation, the registry runs it for the selected instance before maintenance resolution. The test checks the order and confirms another instance does not receive the effect.
OpenCode service replacement packages/provider-opencode/src/server/versionProbe.ts, packages/provider-opencode/src/server/v2/OpenCode2Service.ts, packages/provider-opencode/src/server/v2/OpenCode2Service.test.ts	The replacement function checks the binary version and matching service registration, resolves the executable and command, reads optional configuration, and ensures the service. Tests cover version checks, URL matching, and ensure arguments.
OpenCode post-update integration packages/provider-opencode/src/server/driver.ts, docs/user/providers-opencode.md	The OpenCode driver sets afterUpdate. A non-empty server URL triggers replacement, and replacement failures become a ProviderDriverError. The documentation describes the service restart, its effect on running turns, and service environment configuration.

Full details: Title check

Explanation

The title "fix(opencode): updating moves the running server onto the new binary" describes the main change. After an OpenCode update, the selected instance now replaces its outdated background service so the running server uses the new binary. The title follows conventional commit style and is specific enough for a teammate scanning history.

Full details: Linked Issues check

Explanation

The only directly linked issue, #13010, is closed and supplies historical context only. No active directly linked issue supplies coding requirements. The PR does not need to complete the OpenCode 1.x work described in #13010.

Full details: Out of Scope Changes check

Explanation

The changes stay within the stated OpenCode 2.x post-update scope. The provider hook runs only for the selected instance after an update. The service replacement matches the local registered service, preserves service settings, and uses the required PTY handoff. The registry test verifies hook ordering and instance selection. The documentation and tests support this behavior. No demonstrated unrelated change appears in the reviewed summary.

Full details: Description check

Explanation

The description includes the required Problem, Change, Scope and approval, and Verification sections, with detailed behavior and test results. However, it does not meet the scope-and-approval requirement: the linked issue is untriaged, and the author reports no maintainer approval for this focused but non-trivial change.

Resolution

Link a triaged issue or a discussion that contains explicit maintainer approval of the direction and scope. If approval is not available, obtain it before updating this section.

Bind the post-update hook to the installation actually updated

If a user changes an instance's binary path or environment while the updater subprocess runs, ProviderInstanceRegistry rebuilds it under the same ID. Since refreshAfterUpdate reads the registry after runMaintenanceCommand completes, this ID check invokes the replacement configuration's hook, not the installation's hook that the update targeted. For example, updating installation A and switching the binary path to an older installation B during that update causes replaceOutdatedService to replace the configured service using B, even though B was never updated. Capture the update target's instance/installation identity and skip the hook if that target has since been replaced.

Verify the listener before equating loopback addresses

On a dual-stack host, an IPv4-only registered service and a different IPv6 server or SSH tunnel can listen on the same port. This predicate accepts http://127.0.0.1:p and http://[::1]:p as the same service; I reproduced that result with two distinct listeners. When the IPv6 URL is configured, the subsequent Service.ensure replaces the unrelated IPv4 service, interrupting its active turns while leaving the selected server unchanged. Keep address families distinct, or verify the configured endpoint's process identity before accepting these aliases.

- Around line 46-49: Update the Server URL explanation to specify that restart
matching requires the same protocol, port, and host, with 0.0.0.0 matching
127.0.0.1 and [::] matching [::1], as determined by isRegisteredService. State
that other addresses, including localhost, do not trigger the restart and leave
the service on its old version until the user restarts it.

Refresh the cached connection after replacing the service

If this instance has already connected to a service older than 2.2.5, replacing it here leaves the adapter using the old version indefinitely. OpenCode2Server.make caches its first connection (v2/OpenCode2Server.ts:129-145), so both adapter reconnects and newly opened sessions receive the old connection.version. The adapter uses that value to enable native goals (v2/adapter.ts:732), meaning native goal handling remains disabled after a successful upgrade to 2.2.5 even though provider status reports the new version. Refresh the cached connection and ensure reconnecting sessions obtain the replacement service’s version.

Reinvalidate sibling caches after replacing a shared service

When two enabled instances share the same OpenCode service, a model read or session opening on the non-selected instance while this hook probes the binary can refill that instance's cache with the pre-restart connection. The added invalidateCaches hook runs before the replacement in this concurrent loop, while the driver's post-replacement forget only clears the selected instance. Consequently, the sibling's subsequent sessions and reconnects can keep using the old connection.version; an upgrade from 2.2.4 to 2.2.5 leaves native goal handling disabled even though provider status reports 2.2.5. Invalidate/reverify sibling connections after the shared service is replaced, rather than relying solely on the pre-replacement invalidation.

Update: merged current main

• merged github/main (b883156e26) with a merge commit, no rebase. one conflict in packages/provider-core/src/server/driver.ts: kept this pr's afterUpdate hook and main's new consumeResetCredit(creditId) signature.
• blacksmith vp run check:changed on the merge passed: format, lint, knip, graphql, typecheck of 27 packages, tests in 6 files (103 tests).
• no other source changes. open bot threads, checked against the code:
  • "refresh the cached connection after replacing the service": already handled. afterUpdate runs openCode2Server.forget on completion, and the registry now runs it before every instance's invalidateCaches, so siblings also drop the old connection.
  • "recognize verified local aliases" (localhost vs a 0.0.0.0 registration): intentional. localhost can resolve to either address family, so matching it could restart an unrelated service; the docs name the accepted forms.

Earlier verification (head ae5ebede3b, before the merge)

verified unchanged head ae5ebede3b47b306046d99e40815fde30221c8f8 on a linux boat vm, using the real dev web app, repository playwright, and google chrome. created the project and threads through the app and ran real codex gpt-6.1-sol and opencode turns. no mocks or demo data.

• on github/main at 04f6cfca87, settings > providers > opencode > update installed binary 2.2.7 but left the registered service on 2.1.3. the app reported "Update command completed, but T3 Code still detects an outdated provider version."
• on the pr, the same update flow with http://127.0.0.1:49555 upgraded 2.1.3 to 2.2.7, replaced service pid 53373 with 56558, and displayed 2.2.7 as authenticated. the original session remained and persistent terminal pid 53415 stayed running. a subsequent prompt in that same thread completed through opencode.
• refresh alone did not restart the stale service. updating with the deliberately unmatched localhost url also left it alone and honestly reported the stale version.
• a saved service environment variable survived. the replacement had no ELECTRON_RUN_AS_NODE, ran in its own agent scope, and still served the same session and terminal after t3's dev server stopped.
• codex gpt-6.1-sol completed turns through the web client before and after the opencode update.
• blacksmith vp run check:changed 17a6a01d84e3adf9f29df2639d6b6079a434e1b2 passed: format, lint, knip, graphql, typecheck of 27 packages, and tests in 6 files. github checks on this head were green; native/mobile jobs were skipped.

short runtime transcript, read through the real opencode client:

main: binary 2.2.7, service 2.1.3 pid 34456; app reports outdated version
pr before update: service 2.1.3 pid 53373, terminal pid 53415 running
pr after update:  service 2.2.7 pid 56558, terminal pid 53415 running
session before/after: ses_e381a2a08ffeuCz06OqSIdnV7b
post-update turn: succeeded in the same session
stop t3 dev: service pid 56558 and terminal pid 53415 still running

full runtime transcript

Not verified

native desktop and ios/android clients, macos/windows process behavior, opencode 1.x, ipv6 matching, remote/tunnel connections, concurrent sibling instances, and a forced service-replacement failure. these need other platforms or additional scenarios; the linux web flow above passed. no source changes or pushes were needed.

🤖 Claude Fable 5.2 responding on behalf of Theo

Continued in #34606. It has this branch's commits unchanged, plus a merge of current main.

• fix(opencode): verify CLI updates when loopback server is still running #22839 landed on main and conflicted with this branch in the user guide. The two now work together: the registered background service is replaced, and every other loopback server keeps the restart hint from fix(opencode): verify CLI updates when loopback server is still running #22839.
• One behavior change: a failed replacement no longer ends the update as "could not verify". The normal version check runs and reports what is running.

Verified in the real app with OpenCode 2.1.3 to 2.2.7: the service moved to 2.2.7 and kept its persistent terminal, session, and password. A localhost URL left it alone.

This PR stays open until that one is decided.

Thanks for this. Main has the change since #34606.

Main now includes your OpenCode background-service replacement, persistent-terminal handoff, environment preservation, and connection-cache invalidation through #34606. I compared all 11 changed files with main: the service helper and connection changes are identical, the binary-probe export is present, and the registry additionally continues verification after a replacement failure.

Closing as superseded.
