# Hydrogen -- Setup Panel & Virgin Reset

This is the platform-generic reference for the Hydrogen setup panel and virgin
reset. The host-platform specifics (the exact install cascade, workspace
import/unregister mechanics, the per-platform step list and state file)
live in your platform bootstrap's version of this skill.

## Zero-Click Goal

The Hydrogen setup process targets ZERO manual clicks for the user. The heavy
lifting is already done at image-build time: the golden workspace image ships
with code-server, gallia, the Adom CLIs, the claude CLI + Code extension, VS
Code settings, and all `hd-*` skills BAKED IN. Setup just provisions that
image, injects the user's session, wires up the relay, and walks the single
human auth gate. If something is missing, Hydrogen downloads it — never tell the
user to install something manually. See the `hydrogen-golden-image` skill for the
baked-image model.

## The Install Steps

The setup cascade is a halt-on-failure, resume-not-restart sequence with
per-step 3x auto-retry. State is tracked per-step (status pending / running /
done / failed, output text, percent complete) and Hydrogen reads it on launch to
decide whether the setup panel auto-opens. The exact step list, ordering, and
state-file name are platform-specific — see your platform bootstrap's version
of this skill.

Conceptually the steps fall into these phases:

1. **Provision the workspace** — ensure the runtime is available, import the
   golden image, create the workspace user, start code-server, verify host
   loopback reachability. This single step subsumes any older
   pull-image / create-instance / start-instance trio.
2. **Activate the editor** — wait for code-server, activate editor extensions
   (baked, installs nothing), reload the editor iframe, prove the
   editor-control API answers.
3. **Wire identity + environment** — set the Adom env URLs, inject the Adom
   session token, re-assert VS Code config backstops idempotently, apply the
   per-session layout.
4. **Wire the relay** — verify the Adom Bridge companion app, start the
   relay inside the workspace, prove direct-connect and register the relay for
   file streaming.
5. **Gates + payoff** — gate on adom-cli reachability (carbon +
   hydrogen-proxy), walk the single Claude auth gate, confirm the editor SSE
   session, verify the proxy holds a real layout, open Claude Code and send the
   first prompt, and finally open welcome.html in Hydrogen's right pane (hard-fails
   if the Welcome tab doesn't appear).

### Steps that NO LONGER EXIST (baked into the golden image)

These are NOT setup steps anymore — they are baked at image-build time and
must not be listed or "run": `install-gallia`, `install-hd-skills`,
`verify-adom-bridge-cli`, `install-claude-cli`, `install-claude-ext`,
`write-vscode-settings`, `set-trusted-domains`, `clean-layout`. gallia, the
Adom CLIs, the claude CLI + Code extension, code-server, settings, and all
`hd-*` skills are baked into the golden image. See `hydrogen-golden-image`.

## Panel Buttons

- **Run All** — executes all pending steps sequentially. STOPS on first failure.
- **Rollback All** — rolls back all completed steps in reverse order.
- **Virgin Reset ▾** — opens the toggle panel (see below).
- **Run** (per-step) — runs a single step.
- **Rollback** (per-step) — rolls back a single step.

## CRITICAL: Run All Stops on Failure

If any step fails, Run All ABORTS (halt-on-failure, after the per-step 3x
auto-retry is exhausted). Remaining steps are NOT executed. The cascade
resumes — it does NOT restart from the first step — so to recover after a
failure: fix the issue, then either:
- Click "Run All" again (it resumes from the first not-done step)
- Click "Run" on the failed step to retry just that one

## Virgin Reset Toggle Panel

Click "Virgin Reset ▾" to expand the wipe options. Each toggle has a
live status badge showing the current state. The ONLY programmatic trigger is
`POST /setup/panel/run-virgin-reset` (see below).

| Toggle (option key) | What it wipes | Status badges |
|---|---|---|
| Install step state (`install_state`) | Resets all steps to pending | CLEAN / EXISTS |
| Workspace (`container`) | PRISTINE wipe + re-provision of the workspace (ONLY Hydrogen's own workspace) | GONE / RUNNING / EXISTS |
| Image tarball (`tarball`, legacy `image`) | Deletes the cached golden image (full re-download) | CACHED / GONE |
| Webview storage (`webview_storage`) | Queued wipe, flushed at next Hydrogen launch (restart_required) | CLEAN / EXISTS |
| VS Code state (`vscode_state`) | Queued wipe, flushed at next Hydrogen launch (restart_required) | CLEAN / EXISTS |
| Adom session token (`adom_token`) | Deletes `hydrogen-session.txt` | CLEAN / EXISTS |
| Claude credentials (`claude_token`) | Deletes the host-side Claude creds backup | CLEAN / EXISTS |

`confirmed_destructive` must be set for the reset to proceed. **"Wipe
Selected"** at the bottom executes the reset for all checked toggles.

The workspace reset is a PRISTINE wipe + re-provision — it backs up Claude
creds first UNLESS `claude_token` is checked. The `webview_storage` /
`vscode_state` wipes are queued and flushed at the next Hydrogen launch
(restart_required), NOT immediate; there is no reboot for the wipe.

CRITICAL — the virgin reset only ever touches Hydrogen's OWN workspace. It NEVER
touches other workspaces or runtimes the user may have on the
machine. The platform-specific commands (and the never-touch-global rule)
are in your platform bootstrap's version of this skill.

## Automated Testing Pattern

For AI-driven ralph loop testing, keep auth tokens so steps don't fail:

```
Checked:   install_state, container
Unchecked: tarball (cached, saves the full-image re-download),
           adom_token, claude_token
```

This gives a freshly-provisioned workspace while keeping auth working — the
inject-api-key step and the claude-auth step won't fail.

### Programmatic triggers (the ONLY supported headless paths)

```bash
# Virgin reset — the ONE allowed programmatic trigger
curl -X POST http://127.0.0.1:47084/setup/panel/run-virgin-reset \
  -H Content-Type:application/json \
  -d '{"confirmed_destructive":true,"install_state":true,"container":true,
       "tarball":false,"webview_storage":false,"vscode_state":false,
       "adom_token":false,"claude_token":false}'

# Re-run a single step (optional continue_after to keep going)
curl -X POST http://127.0.0.1:47084/setup/step/test-direct-connect \
  -H Content-Type:application/json -d '{"continue_after":true}'
```

DEPRECATED — do NOT use these; they are now REFUSED (deprecated headless
triggers): `POST /setup/virgin-reset`, `POST /setup/run-all`,
`POST /setup/run-step` (plus deprecated runtime-specific endpoints listed in
your platform bootstrap).

## Key Steps Explained

### Provision the workspace (step 1)
The big one. Ensures the runtime is available (installing it if needed), then
provisions the workspace from the full pre-baked golden image, creates the
workspace user, starts code-server, and verifies host loopback reachability.
This single step replaces the old pull-image / create-instance /
start-instance trio. Platform-specific provisioning commands and any
runtime-install reboot are in your platform bootstrap's version of this skill.

### inject-api-key
Writes the Adom session token into the workspace so adom-cli works. Requires
the user to be signed in. Keep the `adom_token` toggle UNCHECKED during
automated test resets.

### test-direct-connect
Proves the fast workspace→desktop command path. The CLI auto-probes the host
control API and routes through Adom Bridge's direct connect API.

### test-relay (register relay)
Registers the relay (started by the start-relay step) with Adom Bridge for
file streaming via the code-server proxy path. This enables `pull_file`,
`send_files`, and `shell_execute`.

### claude-auth
The single human gate. Restores / validates Claude creds in the workspace
(backed up host-side) and, when needed, drives the in-editor Claude.ai sign-in
via the native browser Browser Picker. Runs LAST before the payoff steps.

### The final gates
`ensure-sse` confirms the editor browser SSE session is connected (so the
Welcome webview-open doesn't 409); `verify-workspace` confirms the proxy holds
a real layout; `welcome` opens Claude Code and sends the first prompt; the
final `open-welcome` gate opens welcome.html in Hydrogen's right pane and HARD-FAILS
if the Welcome tab doesn't appear.

## Workspace Recreation

When the workspace is wiped and re-provisioned (step 1), the new workspace is
a fully pre-baked image. Host port-forwarding for code-server is handled by the
runtime, so the port-conflict / stale-mapping class of bug does not apply.
Other services tunnel through the code-server `/proxy/{port}/` path. The
platform-specific port-forwarding behavior is in your platform bootstrap's
version of this skill.
