* fix(worktrees): stop silently switching existing Windows setup scripts to Git Bash
#6967 derived the Windows setup-runner shell from `terminalWindowsShell`. On
upgrade, any Windows user whose terminal preference resolved to Git Bash had
their existing `orca.yaml` setup script (and issue command) handed to bash
instead of cmd.exe. Scripts authored against the cmd runner — `copy`, `xcopy`,
`set VAR=value`, `if errorlevel 1`, `%VAR%`, backslash paths — broke with no
migration and no warning, and the failure looked like Orca broke the project.
The conflation is also wrong in the steady state: a terminal preference is
per-user, so two people on the same repo got different interpreters for the
same orca.yaml and no project could write a setup script that worked for all
of its Windows contributors.
The interpreter is now a property of the script, declared the standard way:
a leading `#!` line. Native Windows keeps the historical `.cmd` runner unless
the script declares a POSIX shell, so no existing script changes behavior.
`resolveSetupRunnerShell` keeps its role as the feasibility gate — a bash
runner still requires the terminal to resolve to Git Bash, since the launch
command is typed into that shell and uses MSYS `/c/...` paths.
`buildWindowsRunnerScript` now drops a leading `#!` line rather than `call`ing
it, so a declared-bash script that falls back to cmd (Git Bash missing) fails
on a real setup line instead of aborting on errorlevel at line one.
WSL worktrees, POSIX platforms, and SSH hosts are untouched.
* fix(worktrees): keep the cmd setup runner launchable from a Git Bash pane
Adversarial review of this PR found that pinning the runner format per script
reopened issue #6896 one layer down.
- `WorktreeSetupLaunch.shell` had been redefined to mean "the format the runner
file was written in". `resolveSetupRunnerCommand` consumes it as "the shell
that types the launch command", so a Git Bash terminal with a batch setup
script produced `cmd.exe /c "C:\...\setup-runner.cmd"` typed into a bash pane,
where MSYS rewrites the `/c` switch into a drive path: cmd opens interactively
and setup never runs. `shell` is the terminal's family again; the runner file's
.cmd/.sh extension carries the format, and a batch runner launched from a POSIX
pane reuses the existing PowerShell ProcessStartInfo launcher.
- The cmd runner dropped a leading `#!` line and ran the rest as batch, so a bash
script reaching cmd (PowerShell/cmd terminal, or any SSH-to-Windows host) got
its interpreter-agnostic prefix executed before failing mid-way. It now prints
why and exits 1 without running anything.
- A `#!` line's option flags were discarded: `#!/usr/bin/env -S bash -euo
pipefail` lost pipefail because the runner is launched as `bash <path>`. The
generated posix runner now replays declared flags via `set` and drops the
duplicate interpreter line.
- Docs cover the per-user setup command in repository hook settings, which goes
through the same `#!` rule, and describe what the `#!` line does and does not
select.
Tests: composed launch command for a POSIX pane + cmd runner (hooks, shared
runner command, setup sequencing gate, observed-setup signal), the cmd runner's
shebang refusal, and shebang flag replay. Each fails with the source reverted.
* fix(worktrees): replay only real `set` flags and keep the gate in the pane's shell
Two round-2 review findings:
- `#!/bin/bash -l` replayed `set -l`, which exits 2 and aborted the runner under
its own `set -e` before a single setup line ran (all platforms). Only the flags
`set` documents are replayed now; a bare `-o` with no option name is dropped
instead of dumping the shell-option table.
- The wait-for-setup gate picked its language from the runner file, so a batch
runner launched from a Git Bash pane got the PowerShell gate while the agent
startup command was already POSIX-quoted — `Invoke-Expression` cannot parse
`'\''`. The gate now follows the pane; the runner still launches through the
ProcessStartInfo launcher, never through bash.

* Honor configured shells during worktree setup
* Align setup launch paths with selected Windows shells
* Carry setup shell selection through deferred launches
* Prove Windows setup shell routing at its real adapters
* Ground remote PowerShell proof in the real writer
* Preserve Git Bash across deferred setup launches
* Harden Windows setup runner shell selection
- Resolve remote PowerShell binary without local pwsh probe: for SSH/remote
Windows worktrees, isPwshAvailable() reflects only the LOCAL host, so an
'auto' implementation could route the remote runner to a pwsh.exe the remote
lacks. Add resolveSetupRunnerShell(..., { probeLocalPwsh: false }) so remote
auto keeps the always-present powershell.exe; explicit pwsh.exe still honored.
- Preserve native exit codes in the PowerShell runner by checking
$LASTEXITCODE before $?, so a failing native command surfaces its real code
instead of a generic exit 1; $? still catches cmdlet soft-failures.
- Write the PowerShell runner with a UTF-8 BOM so Windows PowerShell 5.1 (the
new default powershell.exe) reads it as UTF-8 instead of ANSI, preventing
non-ASCII setup-script corruption.
- Add unit tests for the remote-probe behavior.
* Restore setup-shell scope narrowing over the rebase
The force-pushed rebase dropped five review-fix commits that were already
on this branch; this reapplies their combined effect on top of the new
base and the hardening commit:
- Keep SSH setup shell selection remote-owned (no local terminalWindowsShell
or pwsh routing for remote hosts; supersedes the probeLocalPwsh guard)
- Preserve cmd setup compatibility outside POSIX shells (no .ps1 runner
family, so the BOM/exit-code hardening is no longer applicable)
- Route WSL setup runners from the project runtime
- Avoid blocking PowerShell probes during setup creation
- Correct SSH and WSL background setup fixtures
* Satisfy the changed-code gates for the setup-shell runner
- createWorktreeRunnerScript took 7 positional parameters, tripping the
changed-code max-params gate; move it to a single options object.
- hooks-runner.test.ts deep-equals the createSetupRunnerScript result, so
assert the cmd shell now returned for native Windows worktrees.
* Carry the setup launch shell through observed and issue runners
- buildObservedSetupCommand takes the runner's launch shell so WSL-routed
Windows-drive setup replays use /mnt/c instead of Git Bash /c
- resolveSetupRunnerShell gates the posix runner on the same Git Bash
resolution the PTY uses, so a missing or non-MSYS bash keeps the cmd runner
- issue-command runners carry their launch shell, and the renderer passes it
when building the queued command
- treat a bare `bash` shell setting as POSIX like `bash.exe`

* fix(worktrees): close counsel P1 gaps for Windows setup shells
Route windowless/headless creates through the shell-aware setup runner when a
PTY controller is available, existence-check explicit Git Bash paths before
committing to .sh runners, thread the resolved shell into issue-command
runners, and document the intentional Git Bash interpreter flip with a narrow
scope table.
* Convert setup env to MSYS form and harden the bare cmd runner launch
C3: a Git Bash setup runner now receives ORCA_*/CONDUCTOR_*/GHOSTX_* path
values in /c/... form, matching the runner path and the shell's own HOME/PWD.
C5: extension-less `bash` resolves to Git Bash everywhere, matching how
resolveWindowsShellStartupFamily already classifies it.
C7: runner paths carrying characters that cannot be quoted on a cmd command
line launch through a delayed-expansion PowerShell shim instead, and the batch
runner disables inherited delayed expansion so `!` in setup lines survives.

* docs: note MSYS ORCA_* paths and bare bash Git Bash resolution
Keep the setup-shell release note aligned with C3 env conversion and C5 bare
bash resolution so the published claim matches runtime behavior.
* revert: drop windows-setup-shell doc allowlist and AGENTS link
Keep the counsel P1/P2 product fixes without expanding the docs allowlist
or AGENTS.md guidance surface.
* fix(plugins): contain Parcel unsubscribe rejections under Vitest
Dev plugin watchers fire-and-forget unsubscribe, and in-process Parcel
can reject when temp watch roots are already deleted. Catch those
rejections so they cannot fail the suite as unhandled errors.
* fix(plugins): keep in-process unsubscribe rejection surface
Swallowing Parcel unsubscribe errors broke mocked unsubscribe tests
that return non-Promises and expect rejections. Contain failures only
in PluginDevWatcher fire-and-forget paths.
