It covers:\n\n- Session lifecycle (hello/welcome, resume, heartbeats, acknowledgement, job listing, close)\n- Job submission, idempotency, lifecycle, cancellation, agent versioning, and cross-session subscription\n- Job event kinds and sequence number guarantees\n- Result streaming (`result_chunk`)\n- Lease capability model, namespaces, subsetting, expiration, and budget enforcement\n- Delegation\n- Trace propagation (W3C Trace Context)\n- Error taxonomy\n- Security considerations\n- IANA considerations\n\n## Diagrams\n\nThe `docs/diagrams/` folder contains paired light/dark sources in two formats:\n\n- **Graphviz `.dot`** — system architecture and job lifecycle state machine.\n- **PlantUML `.puml`** — the §13 example sequence diagrams.\n\nRegenerate SVGs with:\n\n```sh\ncd docs/diagrams\n\n# Graphviz\nfor f in *.dot; do dot -Tsvg \"$f\" -o \"${f%.dot}.svg\"; done\n\n# PlantUML sequences (writes .puml files and renders SVGs)\npython3 generate-sequences.py\n```\n\nRequires `graphviz` and `plantuml`. On macOS: `brew install graphviz plantuml`. On Debian/Ubuntu: `apt-get install -y graphviz plantuml`. See [`docs/diagrams/README.md`](docs/diagrams/README.md) for the full list of diagrams.\n\n## Contributing\n\nSpec changes require an issue opened first with motivation and wire-shape sketch.
