RainbowBird 0642ede8d1 feat(analytics): expand PostHog coverage and forward server business facts (#2038)
## What

Closes the three structural gaps in AIRI's product analytics: the signup
surface had zero instrumentation, the payment funnel had no terminator
in PostHog, and SPA route changes emitted no pageviews. Also adds
semantic events for character cards, desktop-only features, and
data-maintenance actions.

## User paths

- User signs up / logs in / verifies email / resets password / links
OAuth / deletes account → each step now emits a PostHog event from
`apps/ui-server-auth` (previously fully uninstrumented), with
`identify()` wired on session load so anonymous funnel events merge into
the user person.
- User pays via Stripe → webhook writes `product_events` as before, and
the product-events service now forwards `payment_completed` (plus signup
and subscription lifecycle facts) to PostHog via posthog-node
`captureImmediate`, keyed by the Better Auth user id → the
`checkout_started → payment_completed` funnel closes end-to-end.
Per-request LLM/TTS volume is explicitly not forwarded.
- User navigates between routes in any surface (web / desktop / pocket /
docs) → `$pageview` + `$pageleave` fire per route change via the
posthog-js `defaults: '2025-05-24'` preset in the shared
`posthog.config.ts`.
- User creates / imports / duplicates / edits a ccv3 card, switches
stage background, runs destructive data actions (export / import / clear
chats, reset providers, wipe app data), or uses desktop differentiators
(Spotlight send, widget windows, in-app updater, MCP server management,
pairing QR) → dedicated low-cardinality events.

## Notable decisions

- Server forwarding defaults on: `POSTHOG_PROJECT_KEY` defaults to the
shared browser-safe phc_* project key; set it to an empty string to
disable. Postgres `product_events` remains the source of truth.
- Cross-surface events (`oauth_callback_failed`, account lifecycle)
share one stage vocabulary exported from stage-ui so the two emitters
cannot drift silently.
- Events captured right before full-page navigation use `sendBeacon` so
they survive the redirect (checkout, OAuth consent handoff, login
redirect).
- Removed dead wrappers (`trackSignup`, `trackFirstModelSelected`,
`trackModelChanged`) that duplicated live event streams under second
names.

## How tested

- `pnpm -F @proj-airi/server exec vitest run
src/services/domain/product-events.test.ts` — 6 passed, covering the
forwarding allowlist, the `user_signed_up → signup_completed` mapping,
non-forwarded per-request actions, and a throwing sink not failing the
webhook path nor losing the DB row.
- stage-ui suites (`use-analytics`, `use-linked-accounts`, exports
contract) — 22 passed, including new account/card/data/desktop event
assertions.
- Real transport smoke: posthog-node `captureImmediate` against
`us.i.posthog.com` with the production key resolved in 1380ms (one
`server_forwarding_smoke_test` event left in the project; filter by
event name).
- Browser-tested pageviews: `VITE_ENABLE_POSTHOG=true` dev build, two
`history.pushState` route changes each produced a `$pageview` with
`$pathname`, `navigation_type: pushState`, previous-page dwell time, and
the `surface` super property; batched POST to `us.i.posthog.com/e/`
returned 200. Note: posthog-js drops events from automated browsers
(`navigator.webdriver`) by default — the verification session bypassed
the bot filter locally; production config is untouched.
- Typecheck and lint pass for server, stage-ui, stage-pages, stage-web,
stage-tamagotchi, ui-server-auth.

Full verification record:
`apps/server/docs/ai-context/verifications/posthog-forwarding-and-pageview.md`

## Follow-ups (not in this PR)

- Bot channel usage stats (Discord / Telegram) once they route through
server-runtime counters.
- Main-process desktop events (tray menu, global shortcut fire) need
renderer relay plumbing.
- Confirm `payment_completed` arrives in PostHog after the first real
Stripe payment post-deploy.

AIRI Server Auth UI

Auth UI for the hosted AIRI server. It is a Vue/Vite app deployed separately from apps/server and used for Better Auth sign-in, email verification, password reset, profile, and Electron OIDC callback relay flows.

Use When

  • Building user-facing auth pages backed by server /api/auth/* endpoints.
  • Updating login, sign-up, verification, reset-password, account profile, or Electron auth relay UX.
  • Deploying the auth surface to Cloudflare Workers Static Assets.

Do Not Use When

  • Building the main stage app sign-in callback pages that consume OIDC tokens.
  • Adding admin-only operational pages. Those belong in the standalone proj-airi admin repository.

Commands

pnpm -F @proj-airi/ui-server-auth dev
pnpm -F @proj-airi/ui-server-auth typecheck
pnpm -F @proj-airi/ui-server-auth build

Deployment

pnpm -F @proj-airi/ui-server-auth build writes to apps/ui-server-auth/dist. Vue Router owns /ui/*, while Vite assets are served from root /assets/* so Cloudflare Pages can serve static files without rewriting nested asset paths. Cloudflare Pages uses public/_redirects to route /ui/* back to the SPA HTML.

The production GitHub Actions workflow deploys this app to the Cloudflare Pages project moeru-ai-airi-auth with separate auth-account credentials:

AUTH_CLOUDFLARE_ACCOUNT_ID=...
AUTH_CLOUDFLARE_API_TOKEN=...

apps/ui-server-auth/wrangler.toml remains available for Workers Static Assets deployments, but production CI uses Cloudflare Pages direct upload.

Production expects:

VITE_SERVER_URL=https://api.airi.build

The server redirects historical /auth/* URLs to AUTH_UI_URL, which defaults to https://accounts.airi.build/ui.

The server-dev workflow deploys a Cloudflare Pages branch build at https://server-dev.moeru-ai-airi-auth.pages.dev/ui/ with VITE_SERVER_URL=https://airi-server-dev.up.railway.app. Set the server-dev API environment variable AUTH_UI_URL=https://server-dev.moeru-ai-airi-auth.pages.dev/ui when the full dev auth redirect chain should stay on server-dev.
