## 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.

## 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.
