REPAIR → TRANSFER → RESUME
Keep the work.
Not just the answer.
An assistant that remembers where help was used, checks every algebra step, and hands the session back without inventing progress.
01 / Your repair session
Start with a worked solution, including its mistakes.
02 / Shared workboard
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.
