Keep the five released suites in their original registry key order and append content-scopes-530; link the Webstone commit 1287fdf8 and PR #268; rebuild archive/manifest with source_revision set to the parent upload 6ae0fc16 (edition v2.2.0/550 unchanged).
docs: explain the frozen input default content scope
Restore the current README, edition metadata and version history; retain the 550-task edition and add scope annotations for the existing 530-task population. Scope support remains an explicit unreleased PR dependency; no version bump or merge is performed.
Add paired main/full content requirements for 530 frozen tasks
Adds an independently source-bound annotation cohort with main/full acceptance profiles. Existing task suites and historical annotations are unchanged. Full reference bodies remain in the matching approved input dataset; public definitions retain hashes. No provider responses, measured results or credentials are included.
