### What problem does this PR solve? Issue Number: None Related PR: None Problem Summary: Code reviews under `be/src/format_v2` need persistent, directory-scoped guidance for the FileScannerV2 architecture and external-data correctness boundaries. This PR adds a local `AGENTS.md` and repository-local design/review references covering: - TableReader, TableColumnMapper, and FileReader responsibility boundaries - external lake/file format and writer compatibility - common FileReader index, predicate, cache, and virtual-column review checks - Parquet Row Group/Page/Row pruning, indexes, lazy materialization, and I/O behavior - ORC predicate-to-SARG conversion, Stripe/row-index/Bloom usage, and fallback correctness - focused correctness, interoperability, differential, and performance-test expectations Detailed checklists are stored under `docs/` and loaded on demand from the directory-scoped instructions to stay below the Codex instruction-size limit. ### Release note None ### Check List (For Author) - Test: No need to test (documentation-only change; Markdown whitespace, local references, Mermaid fences, and English-only content were verified) - Behavior changed: No - Does this need documentation: No -- This is an automated message from the Apache Git Service.
