MCP task sidecars on a newer protocol are parked instead of restored

MCP helper processes declaring a newer protocol are parked on restore, awaiting a v2 runtime.

What probably matters to youSection of the release

Saved MCP task sidecars tagged with a newer 'sep2663' protocol are skipped by the current restore path with a log saying they need a v2 runtime that isn't the one restoring them.

What

Restoring MCP task helper processes from a saved session now checks which protocol each one declared. Entries on the newer sep2663 protocol are skipped by the older restore path with a log saying they need the v2 runtime.

Details
  • Any protocol value that is not recognised is parked with an error-level log rather than restored blindly.
  • Both restore paths in the bundle carry the guard.
Evidence

sep2663

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
