session-migrate 0.11.0

Highlights

• Read root Codex rollouts written in paginated history mode from canonical
  completed turn items, without replaying provider-only context.
• Fail closed on history bases, subagent projections, conflicting modes,
  unknown modes, and damaged ordinal sequences.
• Add a sanitized Codex 0.153.4 paginated fixture and exercise it through all
  18 target writers.
• Promote native sessions from all 18 supported harnesses and every one of the
  324 ordered migration routes into the default release gate.
• Run credential-free pinned native-client continuations for the complete
  harness matrix in CI.
