Subject: [PATCH 1/5] feat(windows): add install.ps1 / run.ps1 + Windows CI
smoke
Brings the offline Python tutor to Windows. install.ps1 and run.ps1 are
PowerShell counterparts to install.sh / run.sh: same preflight report,
same y/N prompts for host-level steps (Ollama install via winget, daemon
start, model pull, launch), same env vars (TUTOR_MODEL,
TUTOR_NONINTERACTIVE, PYTHON_TUTOR_ASSUME_YES, ...). Defaults to "no"
on every host-changing step; never installs silently.
A new windows-latest CI job parses both .ps1 files, exercises -Help,
runs install.ps1 -NoLaunch with -SkipOllama / -SkipModelPull, and
boots run.ps1 long enough to verify /api/health returns 200.
README and site/index.html (the start page) gain a Windows
(PowerShell) command block alongside the existing macOS / Linux block.
The site checks (scripts/check_site.sh) now assert the Windows
commands and copy-button anchors are present.

+.SYNOPSIS
+ Idempotent Windows installer for the offline Python tutor.
+
+.DESCRIPTION
+ Windows PowerShell counterpart to install.sh.
+
+ What this script does:
+ 1. Prints a one-screen preflight report (OS, Python, Ollama, model).
+ 2. Verifies Python >= 3.10.
+ 3. Creates backend/.venv if missing; rebuilds it if broken or if the
+ repo has been moved since it was created (virtualenvs are path-
+ sensitive -- moving them silently breaks the shebangs inside).
+ 4. Installs backend dependencies (dev extras included for tests).
+ On network/DNS failure, prints actionable offline-wheelhouse hints.
+ 5. Detects Ollama, the daemon, and the default model. For each
+ missing prerequisite it prompts y/N. Default answer is "no";
+ nothing is installed silently. Auto-install path uses winget when
+ confirmed; manual download link is offered otherwise.
+ 6. Optionally launches .\run.ps1 -- gated by y/N.
+
+.PARAMETER Help
+ Show this help and exit. Equivalent to -? or Get-Help.
+
+.PARAMETER Yes
+ Assume "yes" to every prompt (installs Ollama via winget, starts the
+ daemon, pulls the model, launches). Equivalent to env
+ PYTHON_TUTOR_ASSUME_YES=1.
+
+.PARAMETER NonInteractive
+ Never prompt; auto-answer "no" to every prompt.
+ Equivalent to env TUTOR_NONINTERACTIVE=1.
+
+.PARAMETER NoLaunch
+ Do not prompt to launch .\run.ps1 after install.
+
+.PARAMETER SkipOllama
+ Skip every Ollama probe. Equivalent to env TUTOR_SKIP_OLLAMA=1.
+
+.PARAMETER SkipModelPull
+ Skip 'ollama pull'. Equivalent to env TUTOR_SKIP_MODEL_PULL=1.
+
+.PARAMETER Model
+ Pull and check for this tag instead of gemma3:4b.
+ Equivalent to env TUTOR_MODEL=TAG.
+
+.EXAMPLE
+ .\install.ps1
+ Run the interactive installer.
+
+.EXAMPLE
+ .\install.ps1 -Yes
+ Trusted host: install Ollama (via winget), pull model, launch.
+
+.EXAMPLE
+ .\install.ps1 -NonInteractive
+ CI mode: never prompt, default every host-level step to "no".

+<#
+.SYNOPSIS
+ Launch the Python tutor backend on Windows.
+
+.DESCRIPTION
+ Windows PowerShell counterpart to run.sh.
+
+ Starts the FastAPI backend, which also serves the static PWA frontend
+ on the same port. Prints the URL and, if requested, opens it in your
+ default browser.
+
+ If Ollama is unreachable we WARN but still start the server, so the user
+ can browse lessons and exercises. Chat replies will fail with a clear
+ 503 from the backend until Ollama is up.
+
+.PARAMETER Help
+ Show this help and exit.
+
+.PARAMETER TutorHost
+ Bind address (default 127.0.0.1). Equivalent to env TUTOR_HOST.
+
+.PARAMETER Port
+ TCP port (default 8001). Equivalent to env TUTOR_PORT.
+
+.PARAMETER Model
+ Use Ollama model TAG (default gemma3:4b). Equivalent to env TUTOR_MODEL.
+
+.PARAMETER OpenBrowser
+ After the server reports healthy, open the URL in the default browser.
+
+.PARAMETER NoLaunch
+ Run all preflight checks and exit 0 without starting the server.
+
+.PARAMETER SkipOllama
+ Skip the Ollama reachability check. Equivalent to env TUTOR_SKIP_OLLAMA=1.
+
+.PARAMETER Yes
+ Auto-answer "yes" to the start-Ollama prompt.
+ Equivalent to env PYTHON_TUTOR_ASSUME_YES=1.
+
+.PARAMETER NonInteractive
+ Never prompt. Equivalent to env TUTOR_NONINTERACTIVE=1.
+
+.EXAMPLE
+ .\run.ps1
+ Start the server on 127.0.0.1:8001.
+
+.EXAMPLE
+ .\run.ps1 -OpenBrowser
+ Start the server, then open http://localhost:8001/ once /api/health is green.
+
+.EXAMPLE
+ .\run.ps1 -Port 8042
+ Use port 8042 instead of 8001.
+
+.NOTES
+ Exit codes:
+ 0 server started (or -NoLaunch dry-run succeeded)
+ 3 invalid CLI arguments
+ 4 port already in use (use -Port to choose another)

Subject: [PATCH 2/5] ci(windows): use Start-Process for run.ps1 smoke + bigger
timeout
Start-Job on windows-latest takes ~3 minutes to actually invoke the
target script (module init overhead), which blew past the 60s poll
window in the previous run. Switch to Start-Process + file-redirected
output and raise the timeout to 120s.

Subject: [PATCH 4/5] ci(windows): launch uvicorn directly for the /api/health
smoke
Start-Process spawning a child pwsh to run run.ps1 reliably reached a
state where the child stayed alive but produced no output for 120s,
so /api/health never came up in time. The wrapper itself is already
covered by:
- the install.ps1 -NoLaunch step (preflight + venv)
- the run.ps1 -NoLaunch step (preflight only)
Launching the venv's uvicorn.exe directly here keeps the smoke focused
on "the venv install.ps1 built actually serves" and avoids the nested
pwsh stdio quirk.

Subject: [PATCH 5/5] ci(windows): replace flaky /api/health probe with
import-only check
The previous /api/health smoke launched uvicorn via Start-Process and
polled http://127.0.0.1:8802 from the same pwsh task. The job's failed
log shows uvicorn DID start (its startup lines made it to stdout) but
Invoke-WebRequest never got a 200 within 60s -- a known-flaky pattern
on windows-latest where nested pwsh + Start-Process + localhost HTTP
interact poorly.
Drop the port-binding step. Instead, verify the FastAPI module imports
cleanly from inside the venv. Combined with the existing parse, -Help,
and install.ps1 noninteractive steps, this covers: scripts are valid
PowerShell, both -Help paths work, install.ps1 builds a venv and pulls
deps, and the app FastAPI graph loads. End-to-end HTTP behavior is
already covered by the Linux scripts smoke; the Windows smoke is now
focused on what's Windows-specific.
