fix(onboarding): restore the first_data_received_at writer - #1189
JeremyFunk wants to merge 2 commits into
Conversation
…a stamp The only writer of org_onboarding_state.first_data_received_at was the onboarding email service deleted in f0a867c, so every org created since 2026-08-01 got no_data from the audit forever. The audit now treats warehouse telemetry in its lookback as first data and stamps the column lazily, so later runs survive a quiet 24h window.

Suggested reviewers: Merge Risk: 🔵 Low · up to Stamping the first-data timestamp hourly restores the previous behavior, but an organization could miss being stamped if one hourly run is skipped. Aligning the cutoff to the hour boundary is a small fix and worth doing before or soon after merge. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The new background job reuses existing cross-organization query controls and makes organization-specific, write-once updates. No introduced security vulnerability was established. Remaining uncertainty concerns upstream identity attribution and recovery behavior.

The column lost its writer when the onboarding email service was deleted, but the setup audit gates on it and maple-portal reads it. FirstDataService runs on the hourly alerting cron: one cross-org scan of the hourly traces and logs aggregates finds unstamped orgs that are sending, creates their onboarding row if missing (with the org's creation time, as the checklist does), and stamps the column. Its first run backfills. The audit no longer stamps; it still counts telemetry in its own lookback as first data, for BYO-ClickHouse orgs and the first hour. Removes the OnboardingService methods and HTTP schemas left over from the email campaign and the v1 onboarding route.

Warning
FirstDataService never stamps an org that sends only metrics
F1 · Warning · correctness
The discovery scans only activeOrgsByTracesQuery() and activeOrgsByLogsQuery(), so an org whose only telemetry is metrics — a scraped exporter, the Cloudflare/PlanetScale pollers, a metrics-only OTel SDK — is never in the active set and org_onboarding_state.first_data_received_at stays null for it forever. The portal reads that column, so such an org is reported as never having sent data; SetupAuditService.ts:533 counts metricCount toward its own "first data" gate, so the two disagree on what first data is. Either add a cross-org metrics scan over the metrics_sum/metrics_gauge/metrics_histogram tables (there is no hourly aggregate for them) or state in the class comment that metrics-only orgs stay unstamped.

In `packages/backend/src/services/org/FirstDataService.ts:54-68`: `FirstDataService` never stamps an org that sends only metrics.
The discovery scans only `activeOrgsByTracesQuery()` and `activeOrgsByLogsQuery()`, so an org whose only telemetry is metrics — a scraped exporter, the Cloudflare/PlanetScale pollers, a metrics-only OTel SDK — is never in the active set and `org_onboarding_state.first_data_received_at` stays null for it forever. The portal reads that column, so such an org is reported as never having sent data; `SetupAuditService.ts:533` counts `metricCount` toward its own "first data" gate, so the two disagree on what first data is. Either add a cross-org metrics scan over the `metrics_sum`/`metrics_gauge`/`metrics_histogram` tables (there is no hourly aggregate for them) or state in the class comment that metrics-only orgs stay unstamped.
Verify the problem exists at that location before changing it, and keep the fix to those lines.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Align the discovery cutoff with hourly buckets.
The activity queries compare Hour directly with startTime. If telemetry arrives at 10:59, the 11:00 tick is missed, and the next tick executes at 12:00:01, this cutoff becomes 10:00:01. The queries exclude the telemetry's 10:00:00 bucket.
The organization remains unstamped unless it sends more telemetry. This breaks the stated tolerance for one missed tick. Round the cutoff down to the start of an hour.
Proposed fix
- const startTime = formatWarehouseDateTime(now - DISCOVERY_WINDOW_MS)
+ const startTime = formatWarehouseDateTime(
+ Math.floor((now - DISCOVERY_WINDOW_MS) / 3_600_000) * 3_600_000,
+ )📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
