Our analytics identity is not accurate enough. The distinct_id is the first provider login the server finds, so it can change partway through an install's life, and a Codex ChatGPT login gives one id to a whole Team because tokens.account_id is the workspace. We cannot count installs reliably or tell how many installs one person runs.

This keeps distinct_id exactly as it is, so PostHog charts and history do not break, and adds the data we need next to it.

• Every event carries installId: the hash of the install's anonymous id, which never changes for the install.
• New event install.owner_observed { ownerSource, ownerId, observedBy }, sent once per owner per server process:
  • connect: the linked T3 Connect account (server), or the signed-in Connect account of a client that connects.
  • openai: the user_id claim from the Codex CLI id_token or from T3's own ChatGPT sign-in. Not sub (one per login method) and not account_id (the workspace).
  • claude: oauthAccount.accountUuid from ~/.claude.json.
  • device: a random id per client device (localStorage on web and desktop, the existing relay device id on mobile). One device opening two environments links them, with no sign-in needed.
• Clients send only SHA-256 hashes in two new WebSocket query params (clientOwner, clientDevice), and the server accepts only that shape. One shared helper hashes on both sides, so a Connect account gives the same owner id on every surface. The client's Clerk userId is the same value the relay stores as cloudUserId.

Owners are resolved into people at query time in slophouse, which keeps every event. Two Connect accounts are never merged, and weaker ids only attach an install to an owner.

Docs: docs/internals/product-analytics.md explains why distinct_id stays and how installs and owners work. docs/user/telemetry.md lists the hashed account ids we send.

Verification

• distinct_id matches main exactly. A one-off test ran main's identity code and this branch's against the same files for 10 cases (no login, ChatGPT Codex, Codex plus Claude, API-key Codex, logged-in Claude, Claude without userID, malformed Codex and Claude files, Codex tokens without account_id, an existing anonymous id), and every hash matched.
• vp test run for the telemetry, startup, ChatGPT auth and MCP core tests in apps/server; src/authorization and src/connection in packages/client-runtime; src/connection in apps/web; telemetryId in packages/shared. All pass.
• New tests check that:
  • distinct_id follows the old rule while installId stays fixed as logins change;
  • a provider distinct_id still sends when the install id cannot be saved;
  • each owner source is read, and an API-key Codex login adds nothing and logs nothing;
  • owners are sent once, and every event carries installId;
  • the client sends only hashes.
• I logged in to real Claude and Codex accounts in throwaway directories, ran the shipped reader once against those files, then logged out and deleted them. oauthAccount.accountUuid and the id_token user_id claim are present and parse.
• tsc-rs --noEmit passes for server, web, mobile, client-runtime and shared. vp lint on the changed files reports only warnings that were already on main.
• Not checked: a live server receiving these params from a real client.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This PR introduces automatic cross-client install and owner attribution in analytics, including hashed account and device identifiers propagated through authentication and WebSocket connection paths. The behavior is broad, enabled through the existing telemetry flow, and touches authentication-sensitive runtime code.

The requested service-boundary change is supported. apps/server/src/ws.ts performs owner iteration and dispatches one analytics effect per decoded owner. Move this dispatch into AnalyticsService while keeping readClientOwners(request) in the WebSocket setup for request decoding.

🟡 Minor · Do not send analytics without installId. · AnalyticsService.ts:192-202

apps/server/src/telemetry/AnalyticsService.ts:192-202
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Do not send analytics without installId.

When saving the anonymous ID fails, getTelemetryIdentityForHome keeps a provider-based distinctId but returns installId: null. AnalyticsService.record still buffers events, and sendBatch sends them without installId. This affects reachable events such as server.boot.heartbeat and client.connected, violating the documented requirement that every event carries installId.

Suggested fix

Give recordOwners a named operation span.

Wrap the service operation with Effect.fn("AnalyticsService.recordOwners"). This keeps one span for the owner batch rather than adding a span for each owner. As per path instructions, “Use named Effect.fn spans for reusable service operations.”

Note

🤖 Claude Opus 5.5 responding on behalf of Theo

On the two outside-diff and nitpick items from the latest review:

• "Do not send analytics without installId": not changing this. When the anonymous id file cannot be written, main today still sends events under the provider-based distinct_id. Requiring installId would drop events that main keeps, which this PR is designed not to do: distinct_id and existing counts stay exactly as they are. The doc overstated it, so docs/internals/product-analytics.md now says installId is sent when the server can save its state.
• Wrap recordOwners in Effect.fn: done in 06ebda4, to match record.
