MisterRaindrop opened a new issue, #2014:
URL: https://github.com/apache/cloudberry/issues/2014

   Part of #2008. Letters (A, B0–B7, C, D, E) are the PRs listed there; this is 
**B4**.
   
   ### Scope
   The `type`-unset case of #1683 §4: a lake table with no catalog service, 
only object storage. The first catalog to work end to end, so C and D develop 
and test against MinIO and the agent alone.
   - `src/meta/engine_builtin/`: each table's current `metadata_location` in an 
extension-owned table on the coordinator; commit is a conditional update under 
a row lock inside the transaction — atomic with the statement, and across 
tables.
   - Metadata work delegated to B3 by location; the agent holds no state for 
these tables.
   - Other engines open the table by path (HadoopCatalog / FileIO).
   - The two commit regimes (builtin: atomic with the transaction; external 
catalogs: an in-doubt window) written into the engine interface docs.
   
   ### Out of scope
   Sharing a builtin table between two clusters.
   
   ### Depends on
   B2, B3.
   
   ### Acceptance
   - DDL and the full conformance suite green with only MinIO and the agent 
running; rollback leaves the HEAD unchanged.
   - Spark opens the table by path and sees Cloudberry's metadata.
   - Two concurrent writers: one commits, the other errors; no lost update.
