> Requires spt-core **v0.15.0 or newer** (was v0.13.2). This release adds self-checkpointing for
> live agents, automatic resume context, and clearer multi-line message delivery — all built on
> features that arrive in spt-core v0.15.0.

### Added
- **Self-checkpointing for live agents — `/sptc:commune --checkpoint`.** A live agent can now reset
  and rebuild its own context without you running `/clear`. Write a commune containing the marker
  `!!checkpoint!!` and the session clears itself, then wakes back up from that very commune and keeps
  going. A single `!!checkpoint!!` wakes with a default "Proceed with next steps"; a **pair** of
  markers wakes with whatever instruction you write between them. The marker is one-shot — it never
  lingers in your rebuilt context.
- **Automatic resume context.** When a live agent's session starts (or clears), it now pulls its
  durable role, working context, and latest unsynced commune and re-injects them automatically — so
  it resumes where it left off instead of coming back blank.

### Changed
- **Incoming messages are easier to read.** A message delivered from another agent now renders across
  multiple lines — the envelope opening, the body, and the close each on their own line — instead of
  one dense single line.
- **Requires spt-core v0.15.0+** (up from v0.13.2). Self-checkpointing and resume context both rely
  on capabilities introduced in that release; `/sptc:setup` and `spt adapter update` will keep you
  current.
- Adapter version of truth is now **0.7.0** (shown in `/sptc:version` and the release tag).
