Summary
This PR adds merge-on-read prepared tables, DML replay, and physical and
maintenance contracts on top of RTAS. It contributes 320 cases to the 394-case
RTAS catalog and produces 714 combined cases.
This branch also fills the Merge-on-read section in
TEST-COVERAGE.md.Stack
Scope
This layer owns merge-on-read prepared tables, row-level mutation replay, and
merge-on-read-specific physical and maintenance behavior: position-delete
files, mode changes, live-delete interaction, metadata tables, time travel,
rollback, changelog limitations, compaction, snapshot expiration, manifest
rewriting, and orphan removal. Branch and WAP routing belong to the child layer.
Known limitations
This layer adds no known-bug skips. Its four combined-catalog skips are inherited
from RTAS.
