Avoid lazy provider startup for document and procedure completion. Propagate MCP cancellation through completers, cancel lookups during session transitions, and share provider result projection with ordinary operations. Cover cold, starting, warm, queued, cancelled, and closed sessions through MCP composition and provider boundaries.
Deliver complete Evidence directly through MCP with required nullable analysis profiles and immutable per-server delivery settings. Bind selected environments at construction and require typed cleanup outcomes with retained retry ownership.
Remove test-only routing, duplicate session and snapshot metadata, producer-field repairs, and ambiguous provider arguments. Separate artifact byte identity from occurrence classification and retain typed source-map and partial native facts across CLI, MCP, and verifier consumers.
BREAKING CHANGE: obsolete Evidence envelopes, session aliases, incomplete snapshots, and missing normalized producer facts are no longer accepted.
* fix(hopper): diagnose MCP provider failures with stage, state, and request context
* fix(hopper): retain health at the actual provider lifecycle boundary
* test(hopper): distinguish socket loss from later observed process exit
* test(hopper): cover observed exit separately from socket-first replies
