REPAIR → TRANSFER → RESUME
Keep the work.
Not just the answer.
Fix the faulty line, not your whole worksheet. Check the repair, try fresh numbers, and resume later with the help history intact.
01 / Your repair session
Start with a worked solution, including its mistakes.
02 / Shared workboard / repair desk
NOT STARTEDNEW NUMBERS / TRANSFER CARD
03 / Evidence, not a mastery badge
Helped answers and revised answers remain visible. Imported outcomes are recomputed.
04 / Leave. Come back. Keep the context.
A portable session stores original work and actions, not trusted scores. Fingerprints detect changed bytes; they do not certify who did the work.
MCP activity and implementation
· Protocol 2025-11-25 · Official SDK 1.29.0
Four real tools orchestrate repair, help, generated practice and a portable handoff. Application state is carried by the client, not an in-memory MCP connection. The service has no accounts or database. Use synthetic equations in this public demo.
