fix(providers): ~/ Binary paths work for OpenCode, Grok and Pi - #29330
A provider Binary path that starts with ~/, such as ~/.local/bin/opencode (a wrapper around flatpak run), was passed to spawn literally. The spawn failed with ENOENT, and Settings → Providers showed "Not found · OpenCode CLI (opencode) is not installed or not on PATH". The same happens for Grok and Pi. Codex, Claude and Muse already expand ~.
Reproduction on main (47f2c8d): set OpenCode's Binary path to ~/…/opencode, an executable wrapper exec opencode "$@". The server logs PlatformError: NotFound: ChildProcess.spawn (~/…/opencode --version) and the provider shows "Not found". The same wrapper given as an absolute path is detected (v1.18.18, authenticated, 120 models). Grok and Pi with ~/… wrappers also show "Not found".
Change
The OpenCode, Grok and Pi drivers now build effectiveConfig with binaryPath: expandHomePath(config.binaryPath, yield* HostProcess.HomeDirectory), the same line the Codex, Claude and Muse drivers use. Each driver also passes effectiveConfig instead of the raw config to its orchestration adapter's create. Without that, Settings would report the provider ready while starting a turn still spawned ~/…. Bare command names and absolute paths are unchanged.
The issue reports OpenCode. Grok and Pi have the same defect on the same code path (reproduced on main), so they are fixed the same way here.
Verification
Focused tests, one per driver. All three fail on main with the raw path and pass with the fix:
packages/provider-opencode/src/server/driver.test.ts: "probes and starts a ~/ binary path from the home directory". On main: expected [ '~/bin/opencode' ] to deeply equal [ '/test-home/bin/opencode' ].
packages/provider-grok/src/server/driver.test.ts: "probes a ~/ binary path from the home directory". On main the raw ~/bin/grok is spawned.
packages/provider-pi/src/server/driver.test.ts: "launches a ~/ binary path from the home directory". On main: expected [ '~/bin/pi' ] to deeply equal [ '/test-home/bin/pi' ].
vp run check:changed passes: format, lint, knip, typecheck of 11 packages, and tests in 4 files.
Runtime check: the web dev server on a fresh database, with ~/… Binary paths pointing at executable wrappers for opencode, grok and pi.
…rok and Pi
These tests reproduce #29302: a binaryPath starting with ~/ reaches the
spawned command unexpanded for the OpenCode, Grok and Pi drivers, so the
status probe fails with ENOENT and the provider shows "Not found".

A Binary path such as ~/.local/bin/opencode reached spawn unexpanded for
the OpenCode, Grok and Pi drivers, so the status probe failed with ENOENT
and Settings showed "Not found". These drivers now expand the path against
the home directory like Codex, Claude and Muse, and hand the expanded
config to their orchestration adapters so sessions launch the same binary.
The Grok reproduction test now checks every argv element, since agent
launches can be wrapped in /bin/sh and the maintenance lookup may spawn npm.

Macroscope's review found this PR approvable — Grok and Pi now resolve home-relative binary paths consistently across provider operations. The assessed changes preserve defaults and ordinary executable paths, with no obvious material risk requiring human judgment.
You can add or adjust custom eligibility rules. Learn more.
The Grok and Pi drivers now expand configured binary paths against the host home directory and pass the expanded paths to their adapters. Tests verify that paths beginning with ~/ resolve to the supplied home directory.
Changes: Provider binary path expansion
Layer / File(s)
Summary
Expand paths before adapter creation packages/provider-grok/src/server/driver.ts, packages/provider-grok/src/server/driver.test.ts, packages/provider-pi/src/server/driver.ts, packages/provider-pi/src/server/driver.test.ts
Both drivers expand config.binaryPath using the host home directory and pass the resulting effective configuration to their adapters. Tests check that the resolved path appears in launched commands and the literal tilde path does not.

Merge Risk: Low · up to 2eddf
Provider discovery is tested, but session startup with home-relative paths lacks regression coverage. The change is mergeable with that follow-up.

Explanation
Issue [#29302] requires OpenCode to run when its configured binary path uses ~/, including a Flatpak wrapper. At the reviewed head, packages/provider-opencode/src/server/driver.ts expands config.binaryPath with HostProcess.HomeDirectory and passes effectiveConfig to its orchestration adapter. The previous review also verified the focused OpenCode regression test. The current head retains this behavior, so the coding requirement is met.

Explanation
The Grok and Pi changes extend the same home-relative binary-path fix to providers with the same defect. The current PR description identifies that shared scope, and the focused tests check the expanded paths. These changes support the reported objective and do not demonstrate unrelated scope.

Add session-launch assertions to all three driver tests.
instance.snapshot.refresh exercises only status or runtime probing. It does not call the adapter’s openSession. Reverting only config: effectiveConfig to config: config can therefore leave these tests passing because the probe paths use effectiveConfig separately.
Open a session through each returned driver instance and assert the expanded binary path. Include the OpenCode 1.x selection. Keep these checks in the driver tests because the regression is the driver-to-adapter handoff; adapter-only tests cannot detect the driver passing the raw configuration.

Require a server startup attempt.
The version probe also adds an entry to binaryPaths. This assertion can therefore pass if startOpenCodeServerProcess is never called. Record probe and startup paths separately and assert that both are present.

Update the test around `startOpenCodeServerProcess` to track version-probe and
server-startup paths separately, then assert that each is present so the test
verifies an actual startup attempt.

Thanks for fixing these paths! OpenCode home-relative binary paths are already covered on main by #29326 (10cd1a5). Could you cut this PR down to the remaining Grok and Pi fixes and their tests, and update the issue reference accordingly?

Test the Pi session command.
The recorded launches come from snapshot refresh, not instance.orchestrationAdapter. If the adapter receives the unexpanded configuration again, this test still passes while RPC session startup uses ~/bin/pi. Extend this case to open a session and assert the RPC launch command.

As per coding guidelines, “Backend behavior changes ship with focused tests for that behavior.” As per path instructions, request a missing test only when it would catch a real regression.

On each independently installed commit, start the real development server with a fresh database and the same synthetic project. Configure executable wrappers as ~/bin/grok and ~/bin/pi, refresh status, and start a thread requesting PATH_OK. Repeat using each wrapper's absolute path.
Linux; Grok 1.0.77 and Pi 1.5.2. Web: Chromium, dark theme, 1280×1000 CSS viewport at scale 2; matching physical-pixel crops. Terminal recordings: real server RPC and T3 CLI, 1280×800 at 15 fps, light theme. No tests used as evidence.
Base never invokes either home-relative wrapper during turn startup. Head invokes both; Pi completes with PATH_OK. Grok launches and answers ACP initialization, then fails because the installed CLI does not advertise T3's requested xai.api_key authentication method. Its absolute-path control reaches the identical authentication failure on both commits. This verifies Grok path expansion and process launch, but not successful authenticated session creation or turn completion.
AI-assisted; verified with the tests and tools listed above.
Not shown:
Successful Grok authenticated session creation and turn completion: Grok 1.0.77 advertises grok.com authentication, while T3 requests xai.api_key. Head and both absolute-path controls launch the CLI and reach the same mismatch. The home-relative process launch itself is verified.
Text-generation operations using the expanded configuration were not exercised; evidence covers provider detection and orchestration turn startup.
OpenCode turn completion was not established. OpenCode already expands home-relative paths on base, and the pinned diff changes only Grok and Pi.
