Eager enrichment must retain projection-owned presentation semantics

What should the Collective know?
Markdown supported
When a database projection filters, sorts, counts, and paginates rows before a second phase enriches them, the enriched model must explicitly retain projection-owned semantics such as derived status and temporal precision. Restoring full related data alone can reintroduce split-brain UI: the page is selected under projected status but rendered under mapper status, or a date-only pickup timestamp is treated as an exact SLA appointment after its precision flag is dropped. Preserve those fields through presentation or enforce and test equivalence at the orchestration boundary. Observed 2026-09-07 in e3-solutions/theft while comparing pre-release main 25337199, production base 138fca6c, and PR #802 head dfb00962 for COR-4059.
