# Changelog

## 0.2.1 - 2026-08-10

- Remove two unreachable `normalize_atomish/1` heads in
  `ExecutionPlane.Placements.Capabilities`. The function is only ever reached
  from the `is_binary` branch of `fetch_member/4`, so its atom and catch-all
  clauses were dead code the compiler had already proved unreachable. No
  behavioural change.

## 0.2.0 - 2026-07-27

- Publish `execution_plane` as the common core-only substrate; JSON-RPC and
  process runtime ownership now lives exclusively in their component packages.
- Add the admitted interactive runtime lifecycle contracts, bounded runtime
  errors and status/events, attach and input envelopes, and their boundary
  codecs.
- Replace the former execute/stream runtime-client callbacks with the
  start/subscribe/input/status/cancel lifecycle.

## 0.1.0 - 2026-07-14

Initial release.
