Problem

OpenCode shell tools can return when a background command launches. T3 now keeps that command in its existing background activity UI until it exits or is stopped, retains captured output, and preserves native completion notifications and continuation turns.

Change

The adapter scopes tracking and Stop to the owning session and its descendants. Recovery uses the experimental shell-job inventory on OpenCode 2.2.6+, with shell-list fallback on supported older servers. After a cold resume, recovered output, terminal state, and idle roster snapshots persist through the existing session event pump before another turn starts. New session-scoped activity is restricted to attached threads and uses the persisted run identity when available so it stays in the current timeline. Polling reads run outside the adapter lock, with stale results discarded after Stop, exit, or another read. Recovery and Stop retain bounded I/O. Final reads retain the output tail, including diagnostics beyond the first four pages. The SDK remains pinned to 2.0.28, and main's native goals, todo checklists, and image jobs are preserved.

Scope and approval

Maintainer-directed implementation of native OpenCode background shell tracking from the T3 Code handoff. Scope covers shell lifecycle, output retention, recovery, ownership, and Stop using existing background activity services and rendering. The session event pump extension is needed to persist recovered activity while no turn is active. No SDK upgrade, new UI, or provider-wide infrastructure is included. The author, Yash-Singh1, is explicitly listed in the repository's contribution-triage exemptions, verified against upstream main.

Verification

Validation: vp run check:changed passes. Focused regressions cover output paging, exit codes, idle recovery, persisted run anchors, ownership, cancellation failures, and a stalled poll that must not block turn completion or Stop. Real OpenCode UI turns used MiniMax M3.1 Flash Free against isolated development state and covered launch, Details and retained output, natural completion, continuation, and explicit Stop. Cold-idle persistence and remote-server paths use protocol fixtures; native mobile was not exercised.

Approvability

Verdict: Approved at b368b81

Macroscope's review found this PR approvable — This adds cross-turn visibility, recovery, and explicit stop support for existing OpenCode shell jobs. Session-scoped filtering and bounded output handling limit the change’s reach without introducing new command execution.

Walkthrough

The OpenCode v2 adapter tracks native shell jobs as background command work. It reports shell output and completion, includes shells in pending-work state, recovers owned jobs after reconnect or resume, and supports stopping tracked tasks. Session-scoped events persist recovered command activity without creating a run.

Changes: Background shell tracking and persistence

Layer / File(s)	Summary
Shell inventory API and replay setup packages/provider-opencode/src/server/v2/OpenCode2Client.ts, apps/server/src/orchestration-v2/Adapters/OpenCode2AdapterV2.testkit.ts, apps/server/src/orchestration-v2/Adapters/OpenCode2AdapterV2.test.ts	The client adds a validated shell-job inventory operation. Replay helpers map shell and job endpoints to operations. Resume fixtures cover inventory requests for supported versions and reconnect scenarios.
Shell tracking and output reporting packages/provider-opencode/src/server/v2/adapter.ts, apps/server/src/orchestration-v2/Adapters/OpenCode2AdapterV2.test.ts	The adapter tracks shell-tool launches, reads and retains output, processes shell lifecycle events, and emits command results. Tests cover output, completion, polling, and interruption.
Pending work, recovery, and stop handling packages/provider-opencode/src/server/v2/adapter.ts, apps/server/src/orchestration-v2/Adapters/OpenCode2AdapterV2.test.ts	Running shells appear in background-task rosters. The adapter recovers shells on reconnect and resume, stops owned shells, and exposes stopTask. Tests cover ownership, recovery, and stop failures.
Session-scoped event routing and persistence packages/provider-core/src/server/ProviderAdapter.ts, apps/server/src/orchestration-v2/ProviderSessionManager.ts, apps/server/src/orchestration-v2/ProviderSessionManager.test.ts	Provider events add sessionScoped flags. The event pump directly persists qualifying updates for the current runtime and attached thread, and finishes associated live command output. Tests cover runless command recovery, thread isolation, and completion without creating a run.

Merge Risk: Minimal · up to b368b

This change tracks native OpenCode shell jobs as background work and recovers them after reconnect or resume. A recovery timeout no longer leaves running shells in the roster without a command item. No concrete merge-blocking risk remains in the reviewed change.

- Around line 3180-3185: Run recoverShells under the adapter lock so its shared
shell and roster mutations cannot overlap with polling or event handling; place
the timeout inside the permit and preserve the existing error-ignoring behavior.
Apply the same locking change at both recoverShells call sites, and verify
resumeThread callers do not already hold the non-reentrant lock.
- Around line 1500-1505: Bound the client.shell.output request in
readShellOutput with an appropriate existing timeout so every caller is
protected from a stalled read while follow holds the global lock; preserve the
current request parameters and output handling.
- Around line 3801-3803: Update stopBackground’s stopShell call to run under
lock.withPermit for the full operation, preventing overlap with handleEvent’s
shell-state mutations. Handle and log stopShell failures locally so they do not
prevent the remaining subagent-stop work from running.
- Around line 1593-1602: Update recoverShells to handle transient failures from
client.shell.get without aborting the loop, while preserving the existing
ShellNotFoundError behavior; ensure syncRosterAncestors still runs after lookup
failures. Also ignore and log readShellOutput errors so a failed output read
does not stop recovery of later shells.
- Around line 1535-1546: Bound the client.shell.remove operation in the stopTask
flow with the established INVENTORY_TIMEOUT mechanism so it cannot wait
indefinitely while holding the session lock; preserve the existing onError
behavior that resets shell.stopping.

Note

Generated by GPT 6.1 Sol

The remaining description warning applies the small-obvious-fix exemption, but this PR relies on the explicit author exemption instead. Yash-Singh1 is listed in the trusted upstream TRIAGE_EXEMPTIONS.td, verified again before merging, and the Scope and approval section links that basis. This was maintainer-directed native shell tracking work, with merge authorization from the maintainer.

I checked functionality and scope before the merge decision. On b368b81, CI and both bot checks pass, Macroscope approves, and every review thread is resolved. The local changed-file check passed with 222 tests. The scope remains shell lifecycle, retained output, session ownership, recovery, and Stop using existing activity rendering and services. No SDK upgrade or product-default change is included. Real isolated UI verification covered launch, output, natural completion, continuation, and Stop; cold-idle recovery and remote paths use protocol fixtures, and native mobile was not exercised.
