synapse-migration

1> **Telemetry — MANDATORY.** Every `api.fabric.microsoft.com` call must carry
2> `x-ms-fabric-skill: synapse-migration` (`az rest`: `--headers "x-ms-fabric-skill=synapse-migration"`),
3> including every LRO poll, `fabric_lro` and retry. Snippets omit it — add it anyway.

5> **OFFLINE LAKEHOUSE ARTIFACT FAST PATH — DECIDE FIRST.** For a no-live-call request with complete supplied inputs and contracts, load only the [fast path](resources/dedicated-pool-to-lakehouse.md#offline-lakehouse-artifact-fast-path); do not load `migration-planning-reference.md`, `dedicated-pool-conversion.md`, or implementation scripts. Use one generator for artifacts and final-byte hashes, then one verifier. Do not inspect generated files or run post-pass spot checks. For every optional non-null source default, set `missingValueBehavior` to `UseSourceDefault` and restore that default before validation. Do not use this path for a Warehouse target; incomplete and large-procedure requests use their own routes.

7> **CRITICAL NOTES**
8> 1. To find workspace details (including its ID) from a workspace name: list all workspaces, then use JMESPath filtering.
9> 2. To find item details (including its ID) from workspace ID, item type, and item name: list all items of that type in that workspace, then use JMESPath filtering.
10> 3. Treat a source Dedicated SQL Pool as read-only. Do not run source DDL, DML, stored procedures, or create sample objects.
