+# bubble.io exit assessment
+
+Assess the live coulomb.social bubble.io product, export its data model, decide
+the v1 feature cut, and rehearse migration into a tenant-keyed relational
+schema. This plan originates from the CUST-WP-0058-T08 seed in
+`the-custodian/docs/coulomb-social-rebuild-seed.md`.
+
+Repo bootstrap (INTENT, SCOPE, TRSL LICENSE, State Hub registration, agent
+files) was completed as part of opening this workplan.
+
+## Inventory bubble.io app
+
+```task
+id: CSOC-WP-0001-T01
+status: todo
+priority: high
+state_hub_task_id: "240a97c5-1f57-4da6-a75b-d7b3416afdd1"
+```
+
+Inventory the current bubble.io app: pages, workflows, data types,
+integrations, external services, and content surfaces that must be preserved
+or deliberately dropped. Record findings under `docs/bubble-inventory/` (create
+as needed).
+
+## Data export and schema mapping
+
+```task
+id: CSOC-WP-0001-T02
+status: todo
+priority: high
+state_hub_task_id: "0bc6eea3-030d-4987-b203-15ccd4f94fcb"
+```
+
+Produce a full data dump from bubble.io and map it to a relational model that
+is tenant-keyed from migration one (business-app service contract §1.3).
+Document the mapping and export procedure under `docs/migration/`.
+
+## Feature cut decision (human gate)
+
+```task
+id: CSOC-WP-0001-T03
+status: wait
+priority: high
+state_hub_task_id: "35a0af87-2f22-4fae-8c82-e3cc4f77f074"
+```
+
+Decide rebuild-as-is vs reduced v1 scope. **Human gate — Bernd.** Capture the
+decision as a decision record under `docs/decisions/` (or State Hub decision)
+before CSOC-WP-0002 implementation scoping proceeds.
+
+## Migration rehearsal
+
+```task
+id: CSOC-WP-0001-T04
+status: todo
+priority: medium
+state_hub_task_id: "2e5be321-3d76-4d7a-86b1-cbe4eb554bd7"
+```
+
+Import the exported data into the v1 schema on a dev instance. Record what
+failed, what was lossy, and what must change before cutover. Depends on T02
+and a scaffolded schema (may start as a schema-only dry run).
+
+## Acceptance
+
+- Inventory and mapping docs are committed and reviewable.
+- Feature-cut decision is recorded with owner and date.
+- At least one migration rehearsal has been run and residual gaps listed.
+- Follow-on implementation workplan `CSOC-WP-0002` can be scoped from T03.
+
+## Notes
+
+- Service contract: `the-custodian/canon/standards/business-app-service-contract_v0.1.md`
+- Delivery lane reference: `vergabe-teilnahme`
+- Preconditions before serving members (ops backup, ops-hub registration,
+  fin-hub cost key) remain platform-side; track against the contract, do not
+  block inventory/export work here.
