Plan: docs/plans/gridcraft-bag-virtual-sheet-v1.md

A virtual sheet may later display already-bound canonical tile coordinates as cells. GridCraft owns parser, worksheet presentation and Excel-specific result semantics only. No GridCraft rewrite, full formula engine replacement or XVERWEIS implementation is necessary for the SAP/AD/Entra/EXO GUID tile POC. A mounted tile must not be mirrored into per-row CellStore objects or local identity authority.

Invariant and boundaries

• DR: version-witnessed coordinate routing, not a Bag-only register or value evaluator.
• DT: immutable class/method interpretation with late ClassView/WideFieldMask fields; historical data replay still requires source snapshots and layout.
• OGAR: normalized, scoped Guid128 correspondence; backsynced AD msDS-ExternalDirectoryObjectId may carry User_{GUID}; distinguish AD objectGUID, sourceAnchor and Entra id.
• Quack / mask-RISC / ndarray: admitted typed/masked folds over borrowed SoA lanes. simd_stride byte LUTs are not a completed cross-table GUID join; no unadmitted Gather/mask reuse.
• POC: one joined logical SAP/PSCustomObject tile with reusable coordinate descriptors, no per-row object hydration; independent oracle, explicit cold/warm timings.
• Outside the first POC: GridCraft formulas and XLSX parity, report-rs workbook convergence, Java runtime, Databricks/DataFusion, Codegraph adapter.

Draft plan only. No production implementation, owner admission, merge, runtime test or deploy is asserted.

Status: document-only architectural correction, reviewed against current source contracts on 2026-11-05.
