+# Prompt For Cursor: Phase 11 Weekend Ingestion
+
+You are working in the `box-box` repository on Phase 11. The Web UI can now
+browse local years, meetings, and sessions. Your task is to make the CLI able
+to populate a whole race weekend/meeting in one backend ingestion flow.
+
+## Read First
+
+Open these files first:
+
+- `documentations/refactor/19-phase-11-weekend-ingestion.md`
+- `cmd/main.go`
+- `internal/ingest/ingest.go`
+- `internal/ingest/ingest_test.go`
+- `internal/ingest/openf1.go`
+- `internal/store/meetings.go`
+- `internal/query/navigation.go`
+
+Only open older docs if you are blocked.
+
+## Goal
+
+Make meeting/weekend ingestion useful for the local-first Web UI. A user should
+be able to ingest a meeting and have all sessions for that meeting populated
+with Race Hub datasets where available.
+
+## Current Shape
+
+The project already has:
+
+- `--ingest-year`
+- `--ingest-meeting`
+- `--ingest-session`
+- session-level Race Hub ingestion datasets;
+- local navigation APIs and UI that depend on ingested meeting/session data.
+
+Confirm the exact current behavior before editing. If `--ingest-meeting`
+currently only stores meeting/session metadata, extend it or add a clearly named
+flag. Prefer the least surprising CLI behavior.
+
+## Work To Do
+
+1. Add meeting/weekend orchestration that fetches sessions for a meeting and
+   ingests Race Hub datasets for each session.
+2. Preserve single-session ingestion behavior.
+3. Return/report per-session summaries clearly.
+4. Keep raw payload provenance for all fetched endpoints.
+5. Make partial failures visible without erasing successful session data.
+6. Add focused offline tests with fake sources.
+
+## Guardrails
+
+- Do not fetch OpenF1 from React.
+- Do not introduce background ingestion from normal page views.
+- Do not persist high-volume car telemetry in this phase.
+- Do not break existing e2e seed behavior.
+- Keep completed historical sessions as the default mental model.
+
+## Verification
+
+Run:
+
+```bash
+go test ./internal/ingest/... ./internal/store/... ./internal/query/... ./internal/web/...
+go build -o /private/tmp/box-box ./cmd/main.go
+cd frontend && npm test -- --run
+cd frontend && npm run build
+npm run test:e2e
+```
+
+## Report Back
+
+Summarize:
+
+- files changed;
+- CLI behavior added or changed;
+- tests run and results;
+- follow-up risks, especially around OpenF1 rate limits or partial sessions.
