fix(server): time out hanging OpenCode CLI version probes - #48
Conversation
- Cap local `--version` checks at 4s so provider status cannot hang forever - Kill the spawned process group on timeout so the CLI actually exits
📝 WalkthroughWalkthroughOpenCode version probes now time out after four seconds and report consistent errors. CLI processes receive scope-based cleanup. A planning document defines future context-limit metadata support for OpenCode token snapshots. ChangesOpenCode runtime reliability
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk:🟡 Moderate · up to The timeout and process cleanup are intended to prevent provider checks from hanging, but the accompanying implementation plan still contains a TypeScript-invalid reassignment and a fractional-cap path that can emit an invalid zero token limit; these should be corrected before treating the PR as merge-ready. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Fix the readonly and reassignment conflict.
modelLimits is declared readonly at line 51, but the inventory-loading branch assigns a new Map at line 92. TypeScript rejects this reassignment, Morty. Remove readonly, or update the existing map with clear() and set().

Validate the rounded value.
Line 125 checks maxTokens > 0 before rounding. A value such as 0.4 produces maxTokens: 0, which violates the PositiveInt contract. Round first, then include the field only when the rounded value is greater than zero. Add this boundary case to the tests, because otherwise the fractional-cap safeguard is decorative.

Add a language identifier to the code fence.
The fence on Line 213 contains shell commands but has no language tag. markdownlint-cli2 reports MD040. Use ```shell or ```sh; even documentation needs adult supervision.

What Changed
Local OpenCode provider status checks no longer hang forever on
opencode --version.checkOpenCodeProviderStatuswraps the local CLI version probe in a 4sEffect.timeoutOrElse. On timeout it returns the existing error probe snapshot (status: "error",installed: true) with a timeout message, instead of blocking the check.runOpenCodeCommanddetaches the child (non-Windows) and registers a scope finalizer that SIGKILLs the process group, so a hangingopencode --versionand any descendants actually die when the timeout interrupts the Effect. Windows useschild.killwith a 1s force-kill.Effect.never) plusTestClock.adjust("4 seconds")asserts the error snapshot.External-server probes are unchanged — they skip the local CLI version command.
Why
checkOpenCodeProviderStatusspawnedopencode --versionwith no deadline. If the CLI hung (bad binary, stuck node, waiting on TTY), the provider status check never completed. Settings and provider inventory that wait on that check stay stuck, and the child leaked because interrupting the Effect did not kill the process group.A short hard timeout plus process-group cleanup is the smallest fix: the probe already has a fallback path for spawn/parse failures, so timeout is just another failure that surfaces as an error snapshot instead of a hang.
