OrcaWinandOrcaWin ed7849eb7b fix(worktrees): stop silently switching existing Windows setup scripts to Git Bash (#12406)
* 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.

Design System

All UI work — layout, color, typography, spacing, component selection, UX behavior — must follow docs/STYLEGUIDE.md. Use the tokens defined in src/renderer/src/assets/main.css (the canonical source) and the shadcn primitives in src/renderer/src/components/ui/. Don't invent new color values, font sizes, or shadow tiers when a documented one already covers the role. When STYLEGUIDE.md is silent, follow the resolution order in its final section.

Style

Concise/Brief Non-obviosu comments ONLY

  • DO NOT: be verbose, explain the obvious, walk through the code ("WHY not HOW")
  • BE CONCISE. 1 LINE if possible

Lint Rules: Do Not Disable Max Lines

NEVER add a max-lines disable (eslint-disable max-lines, oxlint-disable max-lines, or line-specific variants), and never add a per-file max-lines bump in mobile/.oxlintrc.json.

File and Module Naming

Never use vague names like helpers, utils, common, misc, or shared-stuff for files, folders, or modules. They carry zero info and tend to become dumping grounds. Name files after what they actually contain — prefer the concrete domain concept (e.g. tab-group-state.ts, terminal-orphan-cleanup.ts) over the generic role (tabs-helpers.ts, terminal-utils.ts). If you find yourself reaching for helpers, the file probably has more than one responsibility and should be split, or there's a better name hiding in the code that describes what the functions operate on.

Type Declarations: Prefer .ts Over .d.ts

Considerations

Worktree Safety

Always use the primary working directory (the worktree) for all file reads and edits. Never follow absolute paths from subagent results that point to the main repo.

Cross-Platform Support

Orca targets macOS, Linux, and Windows. Keep all platform-dependent behavior behind runtime checks:

  • Keyboard shortcuts: Never hardcode e.metaKey. Use a platform check (navigator.userAgent.includes('Mac')) to pick metaKey on Mac and ctrlKey on Linux/Windows. Electron menu accelerators should use CmdOrCtrl.
  • Shortcut labels in UI: Display / on Mac and Ctrl+ / Shift+ on other platforms.
  • File paths: Use path.join or Electron/Node path utilities — never assume / or \.
  • Windows setup scripts: the setup/issue-command runner is a .cmd batch file unless the script starts with a #! line — never derive that from the user's terminal-shell preference, and never launch a .cmd runner with a bare cmd.exe /c from a Git Bash pane (MSYS rewrites the /c). See docs/reference/windows-setup-shell.md.
  • Linux native modules: keep the glibc floor at Ubuntu 20.04 / glibc 2.31. A module compiled from source on a newer runner can reference symbol versions absent on the floor and crash the app on startup. See docs/reference/linux-glibc-compatibility.md; packaging fails if a bundled native binary needs newer glibc.

SSH Use Case

All changes must consider the SSH use case. Don't assume local-only execution.

Folder Workspace Use Case

All changes must consider folder workspaces as well as git worktrees. Don't assume every workspace is a git worktree.

Git Binary Compatibility

Orca runs the user's Git binary on native, WSL, and SSH hosts, which may all have different versions. Treat Git 2.25 as the core-workflow baseline and follow docs/reference/git-compatibility.md.

When adding or changing a Git command:

  • Check when every subcommand and option was introduced. For newer behavior, keep a baseline-compatible fallback or degrade safely.
  • Use GitCapabilityCache with a narrow unsupported-error predicate so recurring operations do not retry a known-invalid command. Do not rely only on git --version; wrappers such as simple-git do not remove host-version differences.
  • Scope capability state to the host that executes Git: native, WSL distro, SSH provider, or relay connection. Cover the first fallback, later cached calls, concurrent probes, and relevant host isolation in tests.
  • Keep the real-binary compatibility contract in PR CI current. When adopting a newer Git feature, add its version boundary so the preferred command and fallback both run against representative Git releases.
  • Preserve commands that begin with global Git options such as -c before the subcommand, including auto-maintenance suppression used by worktree-create fetches.

Git Provider Compatibility

Source-control and review changes must consider GitLab and other supported git providers, not only GitHub. Keep provider-specific behavior behind explicit checks, and avoid GitHub-only naming for generic review concepts.

GitHub CLI Usage

Be mindful of the user's gh CLI API rate limit — batch requests where possible and avoid unnecessary calls. All code, commands, and scripts must be compatible with macOS, Linux, and Windows.
