Windows SSH targets can already attach to a preinstalled compatible Herdr, but cannot provision the complete package when it is missing or unsuitable. This PR lets interactive direct attach and saved-machine setup install it after confirmation. Background reconnect remains discovery-only.

Windows package setup stays behind the existing Windows dispatch; the Unix install flow and source resolver retain their master behavior. The change reuses the bundled installer for validation and activation, keeps managed SCP path handling, and preserves compatible running servers. Desktop hosting, PTY transfer, and Windows live handoff remain outside this PR.

Validation:

  • Native Windows just check: passed (2,940 Rust tests; required formatting, clippy, maintenance, architecture, integration assets, docs, and build checks).
  • Existing remote unit tests: 81 passed.
  • Existing Windows package installer acceptance: passed against a package built from this worktree; user PATH restoration verified.
  • Native SSH noninteractive attach: refused installation and left the unique named server stopped.
  • Local FAST review: two clean signoffs on 8e5df4e. Explicit deslop: clean.

📝 Walkthrough

Walkthrough

Windows remote attach now discovers compatible binaries from PATH and the active managed release. It can copy and install the complete Windows package through SSH and PowerShell. Client status reports the remote_host_bridge capability, which participates in Windows endpoint validation. Package identity and reuse rules distinguish standard and custom packages. Tests cover scp options, installation commands, candidate ordering, capability checks, and status output. Documentation describes the updated Windows behavior and HERDR_REMOTE_BINARY requirements.

Priority: ➖ Normal

The current PR head appears safe to merge, with no actionable new failures identified in the changes since the previous review.

Summary

  • Discovers compatible executables from PATH and the active managed Windows release.
  • Uploads the embedded installer and Windows ZIP using the managed SSH configuration.
  • Validates package content, activates the managed release, and verifies remote-host capabilities.
  • Advertises the Windows remote-host bridge in client status and documents the new behavior.
  • Isolates Windows package provisioning from the existing Unix binary installation flow.

@Pimpmuckl Final static sanity check is complete.

I found no blocking issue in the current head.

The SCP URI handling now preserves Windows paths that contain spaces, %, +, and UTF-8 characters. The legacy host:path transfer form is unchanged. The managed SCP ControlPath is now quoted when it contains spaces.

I did not run the Windows SSH acceptance tests in this inspection sandbox.

@Pimpmuckl Full static review is complete against master.

I found no blocking issue in current head 8e5df4eeaa24532cf29f53c07ace106a39658887.

The Windows package setup is isolated in prepare_windows_remote_herdr. The Unix install flow and source resolver remain unchanged except for blocking Windows executable seeding.

Saved-machine background reconnect uses discovery only. It checks Windows PATH and the active managed release. It does not prompt, install, or update.

The remote installer passes the ZIP, package identity, and SHA-256 digest to install.ps1. The installer verifies the digest and the complete staged Windows package before activation.

I did not run tests in this inspection sandbox. Your reported just check and installer acceptance results cover that validation.
