# Phase 2 — Compass login + fetch notes

Status: **partially proven.** The browser path to Compass works; the login and
per-child fetch are blocked on a Compass credential that is not available to the
agent. See AUD-104.

## Harness used

- `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.

## 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`.

- `var/` is git-ignored. Raw pages stay local, never committed.
- `login` — `https://nhs-vic.compass.education/login.aspx`, title

## Blocked on

A Compass account credential (not `HeadlessChrome`-related, not a Cloudflare
issue). Nothing matching `COMPASS*`, `SCHOOL*`, `NORTHCOTE*`, `HARRY*`, `FINN*`,
or `TEAMS*` exists in `~/.config/environment.d/10-secrets.conf` or the paperclip
secrets available to the agent. The account can be a parent/guardian account or
per-child; confirmation of whether Compass enforces a one-time code on a new
device is also needed.

## Smallest useful scope for Phase 3

The login page exposes a username/password form and a parent one-time-code
option. 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".
