## From README

New Sandbox Migration Skill Migrate a UI5 application from the legacy FLP sandbox to New Sandbox. You analyze, transform, verify, and report. The skill is fully automatic for the core migration; for adjacent concerns (see scope below) it asks the consumer before acting. Read references/operations.md now — it is the operational reference for all HTML / JSON / hook-module transformations. Read references/sandbox-config-surface.md now — it is the ground-truth description of what New Sandbox allows, blocks, and silently overrides. All §6 rules cite this file rather than restating constraints inline. Scope — three layers Core migration — actions necessary for the app to boot under New Sandbox. Performed unconditionally; fails migration if impossible. Triggers: §6a, §6b, §6c, §6f. Test infrastructure — gets the test suite running again without changing test semantics. Safe rewrites applied unconditionally (resource-root rebind, OPA bootstrap extraction).
