Replace obsolete per-student teacher approval with the current public-fork flow: learner /load proof, App installation, enabling fork Actions, explicit /submit, and independent disconnect versus delete-work controls. Require connector v0.5.2 or later.

Pin the paired immutable grader revision whose protected README hash matches these instructions. The rubric and all protected exercise code are unchanged. Existing forks keep working with their older pinned workflow.

Validation: starter tests and whitespace passed; paired grader suite has 20 passing checks. New-pin live rehearsal follows this update. No failed or skipped local checks; full interactive Claude session remains unrun.

Paired live verification passed: updated the fictional local exercise to the new immutable starter/checker revisions, fast-forwarded the public rehearsal fork baseline, and explicitly submitted its updated solution PR. The actual GitHub Actions run completed, the App received the completed-run delivery with HTTP 200, and replaying that actual payload into the isolated local backend produced a saved 100/100 score using App-authenticated artifact reads. No synthetic score callback was used. Earlier incomplete/passing revisions remain saved as 5/100 and 100/100. Interactive Claude model behavior and a production customer score remain separate checks.
