Sprint 126 Plan: Campaign Checkpointing, Resume, and Export

Context

Sprint 125 added deterministic multi-target debug campaigns and safety envelopes. Sprint 126 adds checkpoint capture, deterministic resume planning, and export bundles so agents can pause/recover work and produce machine-readable artifacts.

---

Goals

1. Add campaign checkpoint models and deterministic storage
2. Add deterministic queue/resume planning utilities
3. Add MCP tools for checkpoint save/list/resume and export
4. Preserve deterministic ordering and replayability

Architecture Gate

• Checkpoint ordering must be deterministic and stable
• Resume must use latest checkpoint by deterministic rule
• Export bundles must be machine-readable and replay-friendly
• Max 600 lines per header
