PROJECT:
GP-PROJ-001 — Grand Project

A Special One implementation round is authorized for the next genuine gap:
GP-FWK-010 — Storage/file picker.

Use the live GPO only as the authority. Verify canonical main first, inspect the canonical repository evidence for storage/file behavior, and implement only the smallest coherent file-picker slice that is genuinely missing. Reuse the accepted shared pagination and search foundations where relevant, especially file browsing, search, filters, and query-state preservation. Do not broaden into unrelated ServiceVault work.

Rules:
- Allocate a fresh unique CMD-* source-run ID.
- Use the permanent PowerShell Execution Standard.
- Apply the Two-Strikes Rule.
- Inspect canonical implementation before coding.
- Use Minions On Demand; create a new Minion only if no safe existing worker fits.
- Keep MINION-10 documentation-only.
- Preserve GP-FWK-011 as a later adjacent notification UI preview and do not pull it into this slice.
- Run focused Grand Project tests for the selected file-picker slice.
- Run composer run ci if source changes occur.
- Run git diff --check.
- Commit the worker changes, push the worker branch, integrate the accepted work, push canonical main, and verify the remote SHA.
- Stop after the selected slice is complete and verified.
