After SIGTERM/SIGKILL escalation, the stdout stream may not close immediately on all platforms. The unconditional await on outputPromise could then hang indefinitely, defeating the bounded process lifetime guarantee. Race outputPromise against a short follow-up timeout to ensure getOpenCodeVersion always returns within a bounded time.

Only clear recentAnyIdles when the stored marker matches the synthetic idle timestamp for the same session, preventing accidental clobbering of newer idle markers. Add a regression test to verify other sessions keep their dedup state during this bypass path.

When the binary resolved as 'opencode' on PATH is the OpenCode Desktop GUI (not the CLI), it does not respond to --version with prompt exit. proc.exited then waits forever, freezing the installer at 'Checking OpenCode installation'.
Fix: race proc.exited against OPENCODE_VERSION_CHECK_TIMEOUT_MS=1500. On timeout, proc.kill() and treat the binary as failed so the next candidate is tried. Success requires both timedExitCode === 0 and proc.exitCode === 0.

The deep and artistry category fallback chains had no opencode-go provider
entries, causing them to fall through to the ultimate fallback
(opencode/gpt-5-nano) which is not available to opencode-go users.
Add opencode-go entries:
- deep: deepseek-v4-pro -> kimi-k2.6 -> glm-5.1
- artistry: kimi-k2.6 -> glm-5.1

The same output.trim() bug fixed in PR #3909 for doctor exists in the
installer's opencode-binary.ts. Without this fix, `bunx oh-my-opencode
install` would store polluted Electron stdout (e.g., `00:24:25.202 >
app starting { version: '1.14.33', packaged: true }`) as the OpenCode
version in config, breaking downstream version-dependent logic.
- Extract extractSemverFromOutput to src/shared/extract-semver.ts
(precedent: spawn-with-windows-hide is in shared because used by
both doctor and installer)
- src/cli/doctor/checks/system-binary.ts now imports from shared and
re-exports for backward compat
- src/cli/config-manager/opencode-binary.ts uses the shared helper
with `?? output.trim()` fallback to preserve legacy behavior on
non-semver-shaped successful outputs (e.g., custom builds)
- Add 4 installer regression tests covering: clean semver, polluted
Electron stdout (regression for #3765 installer caller), fallback
for non-semver, null when no binary on PATH

MessageAbortedError/worker shutdown could race with scheduled removeTask, leaving background_output's manager.getTask returning 'Task not found' even though the task had completed cleanly.
Fix: add completedTaskArchive (max 500, FIFO eviction). On removeTask, archive non-running/pending tasks with sessionId. getTask falls back to archive on active-map miss. addTask clears stale archive entries on re-registration.
Fixes#3895
When session.status(idle) is converted to synthetic session.idle and recorded in recentAnyIdles, a real session.idle arriving within 500ms was being dropped by the dedup logic. recentSyntheticIdles was cleared but recentAnyIdles persisted, causing TODO-DIAG to red-alert with 'no todossession.idle event'.
Fix: when real session.idle arrives, also clear recentAnyIdles entry so dedup does not drop it. Test renamed and expected dispatchCalls updated 1 → 2.
Fixes#2667
openSync with read-only mode fails fsync on Windows because FlushFileBuffers requires write-permission FD. This caused atomic writes to fail silently, leaving migrated config unwritten and triggering repeated migration + .bak.<timestamp> generation on every startup.
Same root cause as PR #3644 (#3643). Hyperplan disappear is a secondary symptom of plugin load instability.
Fixes#3877
The Electron-based OpenCode build leaks log lines like
`00:24:25.202 > app starting { version: '1.14.33', packaged: true }`
into stdout, so `getOpenCodeVersion` was returning the entire log
line as the 'version'. `compareVersions` then split that string on
'.' and produced a nonsensical numeric array (e.g., `[0, 0, 14, 0]`),
which it judged as < the minimum 1.4.0. Result: doctor incorrectly
flagged OpenCode 1.14.x as below the minimum required version.
Replace the raw `stdout.trim()` return with a small
`extractSemverFromOutput` helper that runs a semver-shaped regex
across the output. A negative lookbehind `(?<![\d:])` skips the
milliseconds segment of timestamps (e.g., `25.202` in
`00:24:25.202`), so the parser locks onto the real version token.
Adds 12 unit tests covering plain semver, v-prefix, pre-release,
build metadata, the Electron regression, timestamp-only stdout,
and various invalid inputs.
