`TemplateBuilderSession` telemetry types and telemetry-server ingestion were added in earlier PRs (#25082, coder/coder-telemetry-server#41), but no code ever produced session events. This adds the missing producer. **Backend**: `POST /api/v2/templatebuilder/sessions` reports wizard entry and compose completion events directly via `api.Telemetry.Report()`, using the same inline pattern as `NetworkEvents` and `UserTailnetConnections`. No database migration or `createSnapshot()` changes needed. RBAC requires `policy.ActionCreate` on `ResourceTemplate.AnyOrganization()`, matching the compose endpoint. **Frontend**: The template builder wizard fires `wizard_entry` on page mount and `compose_completion` on create success or failure. A client-generated session ID (UUID) correlates the two events for the same wizard visit, enabling precise funnel analysis and abandonment detection in BigQuery. Duration is tracked via `Date.now()` in the wizard state. Closes https://linear.app/codercom/issue/DEVEX-599 <details> <summary>Implementation plan</summary> ## Root Cause Analysis The DEVEX-599 ticket diagnosis suggested missing DB tables, queries, and `eg.Go` blocks. That diagnosis assumes the DB-backed periodic snapshot path is required. It is not. Investigation shows two telemetry reporting patterns in the codebase: 1. **DB-backed periodic snapshots** (`createSnapshot()` with `eg.Go` blocks): Used for durable entities like workspaces, templates, users. 2. **Direct inline reporting** (`api.Telemetry.Report(&telemetry.Snapshot{...})`): Used for ephemeral events like `NetworkEvents`, `UserTailnetConnections`, `CLIInvocations`. Template builder sessions are ephemeral events, so the direct inline reporting pattern is the correct fit. ## Backend Changes - `codersdk/templatebuilder.go`: `TemplateBuilderSessionRequest` type with `SessionID`, `EventType` enum, `TemplateBuilderSession()` client method - `coderd/coderd.go`: Route registration in `/templatebuilder` group - `coderd/templatebuilder_handler.go`: Handler with RBAC check, request validation, session ID fallback, and inline telemetry report - `coderd/templatebuilder_handler_test.go`: Tests for wizard entry, compose completion, invalid event type, disabled feature, and member RBAC rejection ## Frontend Changes - `site/src/api/api.ts`: `recordTemplateBuilderSession` API method - `site/src/api/queries/templateBuilder.ts`: React Query mutation - `site/src/pages/TemplateBuilder/wizardState.ts`: `sessionId` and `enteredAt` fields, `createWizardState()` factory for per-mount initialization - `site/src/pages/TemplateBuilder/TemplateBuilderPageView.tsx`: `sessionId` prop, `useReducer` initializer form - `site/src/pages/TemplateBuilder/TemplateBuilderPage.tsx`: Telemetry calls for wizard entry (on mount) and compose completion (on create success/failure) </details> > 🤖 Generated by Coder Agents --------- Co-authored-by: Coder Agent <agent@coder.com>
