Phase 2: prove the Compass login + one-child fetch via patchright

- add scripts/compass-fetch-patchright.mjs: headless patchright logs in with the
  parent account (no 2FA) and stores the per-child pages with a sha256 manifest
- add scripts/package.json + lockfile for the patchright dependency
- docs: the harness clears the Cloudflare GET but not the login POST; patchright
  passes it; record the real per-child URLs and the overdue counts

# Phase 2 — Compass login + fetch notes
Status: **blocked on Cloudflare.** The credential is available and the login
page loads, but Cloudflare's managed challenge blocks the login **POST** under
the headless harness. See AUD-104.
Status: **resolved.** The login and a real per-child fetch work headless and
unattended via **patchright**. See AUD-104.
## Harness used
## What works
- `pi-browser-harness` **v0.11.0**
(`/home/sam/.agents/extensions/pi-browser-harness/package.json`).
- Entrypoint: the pi extension `src/index.ts` plus its long-lived daemon
`src/daemon/index.ts`. The daemon bridges `pi → Unix socket
(/tmp/pi-browser-daemon.sock) → Chrome DevTools Protocol`.
- Chrome: systemd user service `chrome-pi.service`
(`/home/sam/.config/systemd/user/chrome-pi.service`), `--headless=new`,
`--remote-debugging-port=9222`, `--user-data-dir=/home/sam/.chrome-pi`.
- The Phase 2 fetcher (`scripts/compass-fetch.mjs`) talks to the harness daemon
socket and drives the harness's Chrome over CDP.
- **Fetcher:** `scripts/compass-fetch-patchright.mjs` (patchright 1.64.0, headless).
- **Browser:** the system Chrome `/etc/profiles/per-user/sam/bin/google-chrome`
(Chrome 150.0.7871.186), launched by patchright with the automation leaks patched.
- **Credentials:** `COMPASS_USERNAME` / `COMPASS_PASSWORD` from
`~/.config/environment.d/10-secrets.conf` (parent/guardian account).
- **Login outcome:** `POST /login?handler=Login` → `302`, landing on
`Home | Compass`. **No 2FA was required** on this login.
## Compass
- URL: `https://nhs-vic.compass.education/login.aspx` (Northcote High School).
- Login form: `#username`, `#password`, hidden `browserFingerprint`,
`__RequestVerificationToken`, submit `#button1`
(`formaction="/login?handler=Login"`). Also present: a SAML button and
**"Parent sign in with one-time code"** (`formaction="/login?handler=OtpSignin"`).
## Cloudflare finding (important)
Compass is behind a Cloudflare managed challenge. With the default
`HeadlessChrome` user agent, the challenge loops forever
(`title="Just a moment..."`, body "Compass is verifying your connection...").
The fix that works:
1. Override the user agent to a normal desktop Chrome UA
(`Network.setUserAgentOverride`), and
2. run the page in an **isolated browser context**
(`Target.createBrowserContext`) so stale `cf_clearance` / `cf_chl_rc_ni`
cookies from earlier attempts do not loop the challenge.
With both, the challenge clears in ~5 s and the real login page loads. Both are
implemented in `scripts/compass-fetch.mjs`.
### The login POST is the hard part
When the form is submitted (`POST /login?handler=Login`) Cloudflare returns a
**403 managed challenge** and serves `Just a moment...`. Under headless Chrome
that challenge does not clear (`iframes=0`, body "Compass is verifying your
connection..."), so Compass never sees the login. Captured response headers on
the blocked POST show `server: cloudflare`; the GET of the same page passes.
Tested and did **not** fix it: a normal desktop-Chrome UA override, isolated
browser contexts, `Sec-CH-UA` user-agent metadata, focus/visibility emulation,
client hints, and long waits (up to 4 minutes).
The POST passes only intermittently. It was observed returning `200` twice, but
five further attempts (including after a 75 s cooldown, each in a fresh context)
were all challenged. `scripts/compass-fetch.mjs` retries the login on a fresh
browser context up to `COMPASS_LOGIN_ATTEMPTS` (default 4) and fails loudly with
`cloudflare_login_post_challenge` (exit 2) if none get through.
This is the Phase 2 risk: the harness can read Compass but cannot log in from
headless Chrome.
## Proof stored (2026-10-15)
```
var/raw/harry/<runId>/login.html
var/raw/harry/<runId>/login.meta.json
var/raw/harry/<runId>/manifest.json
```bash
cd scripts && npm install # patchright, PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
COMPASS_USERNAME=... COMPASS_PASSWORD=... \
node scripts/compass-fetch-patchright.mjs --child Harry --user-id 27038
```
- `var/` is git-ignored. Raw pages stay local, never committed.
- `login` — `https://nhs-vic.compass.education/login.aspx`, title
`Login | Compass`, **125 741 bytes**, sha256
`4d3b731c34d64b6978d4e1bd7f4a7772ae2b5d8687241db3d7163c2beb325f01`.
## Real data seen (2026-10-15)
## Blocked on
- Harrison (Harry) ROLFE, `userId=27038` — **6 overdue learning tasks**, 1 due next week.
- Finn ROLFE, `userId=31460` — **2 overdue learning tasks**.
- Parent landing page: `https://nhs-vic.compass.education/`.
A reliable way past Cloudflare's managed challenge for the login POST. The
credential itself is no longer missing: it is in
`~/.config/environment.d/10-secrets.conf` as `COMPASS_USERNAME` / `COMPASS_PASSWORD`.
Per-child pages:
- `https://nhs-vic.compass.education/` — `Home | Compass`
- `/Records/User.aspx?userId=27038` (redirects to `Records/UserNew.aspx?userId=27038`) — `User: Harrison ROLFE | Compass`
- `/Organise/Calendar/` — `Compass Calendar`
Options (owner: Sam, because they are host/infra or browser decisions):
Stored under `var/raw/<child>/<runId>/` (git-ignored) with `<slug>.html`,
`<slug>.meta.json`, and `manifest.json` (URL, title, fetched-at, bytes, sha256).
Example run `var/raw/harry/2026-10-15T05-44-47-323Z/`: home 301 968 B, child
profile 448 165 B, calendar 236 234 B.
1. Give the harness a **headful** Chrome (e.g. add `xvfb` to the `.13` NixOS
config and run Chrome non-headless). Managed challenges normally pass there.
2. Supply a `cf_clearance` cookie from a real browser session on the same public
IP and user agent, as a secret to inject.
3. Confirm a non-CF login path (SAML/SSO or the Compass mobile API) to pursue.
## Why not the pi-browser-harness
## Smallest useful scope for Phase 3
The harness (headless Chrome, `chrome-pi.service`, CDP 9222) clears the
Cloudflare **GET** challenge but not the login **POST**: Cloudflare answers
`POST /login?handler=Login` with a 403 managed challenge that headless Chrome
does not solve. Tested and did not fix: desktop-UA override, isolated browser
contexts, `Sec-CH-UA` metadata, focus/visibility emulation, client hints, long
waits, cooldowns. patchright passes it because it patches the CDP/automation
leaks Cloudflare detects. The harness fetcher (`scripts/compass-fetch.mjs`) is
kept for the unauthenticated login-page probe only.
Until a login succeeds we cannot enumerate the per-child page URLs, so the
smallest useful scope cannot be fixed yet. It is expected to be the
"today/planner" page plus the messages/notices list, which is what answers "what
is overdue".
## Non-browser path (checked, then dropped)
- Compass mobile app exists (`com.jdlf.compass` / App Store `778415974`).
- No public JSON API: `/api/*`, `/mobile/*`, `/oauth/token`, `/saml/metadata`,
`/.well-known/openid-configuration`, `robots.txt` all 404 at the origin.
- `/oauth/?OAuthType=...` exists but every guessed type returns
`Invalid OAuthType`; the valid type is unknown.
- SAML button exists (`/login?handler=SamlSignin`, POST); no GET metadata endpoint.
## Notes for Phase 3
- The parent landing page is legacy server-rendered ASP.NET and already contains
the per-child overdue counts (e.g. "6 overdue learning tasks") and the
`userId` links — good first parse target.
- `/Records/UserNew.aspx` is a React/MUI app; the Learning Tasks tab body is
rendered client-side, so task detail will need the app's JSON calls (or the
legacy `Records/User.aspx` view) rather than the stored HTML.
- Keep `var/` out of git; the page HTML contains the family's personal data.

/**
* Phase 2 proof-of-fetch for the Compass / NHS project — patchright path.
*
* The pi-browser-harness (headless Chrome) can load the Compass login page but
* Cloudflare answers the login POST with a managed challenge that headless
* Chrome does not clear. patchright launches Chrome with the automation leaks
* patched, and the login POST goes through. This script:
*
* 1. logs in once with the parent account (COMPASS_USERNAME / COMPASS_PASSWORD),
* 2. fetches the pages we need for ONE child,
* 3. stores the raw HTML + a manifest with a SHA-256 and byte count per page.
*
* Read-only against the school: it only navigates and reads.
*
* Usage:
* node scripts/compass-fetch-patchright.mjs --child Harry [--pages "name=url,..."]
*
* Environment (never commit these):
* COMPASS_USERNAME / COMPASS_PASSWORD parent/guardian account
* COMPASS_CHROME Chrome binary (default: Nix profile google-chrome)
* COMPASS_LOGIN_URL default https://nhs-vic.compass.education/login.aspx
* COMPASS_UA browser user-agent override
*
* Exit codes: 0 ok, 2 Cloudflare challenge not cleared, 3 second factor, 4 login rejected.
