What's New in ETLantic 0.52

Status: Available in ETLantic 0.52.0 (published Beta).

ETLantic 0.52.0 adds deterministic adaptive planning for opt-in profiles. The planner emits the closed etlantic.plan/2 document with a complete candidate matrix, canonical objective, bounded explain output, and a seven-kind physical DAG. Planning remains side-effect free; adaptive runtime execution and external compilation reject the document before I/O.

Existing explicit profiles continue to produce canonical etlantic.plan/1 documents. Native transformation implementations remain explicit /1 escape hatches and are never adaptive candidates.
