# Changelog

All notable changes to this project will be documented in this file.

## [Unreleased]

### Added

- Typed, instruction-sliced Rune invocations with preserved async execution,
  wake-driven resumption, and cancellation tests.
- Minimal single-worker actor runtime with bounded FIFO mailboxes, private
  integer state, structured messages, immutable implementation IDs, explicit
  message effects, inspection, lifecycle events, stop, and restart.
- Runnable two-actor counter demonstration and tests for runaway fairness,
  pending-message isolation, failures, backpressure, and all-or-nothing effects.
- Execution-model decision and Phase 1 runtime documentation.

- Runnable Phase 0 experiment pinned to Rune 0.14.2, covering script execution,
  native calls, async suspension, instruction budgets, frame inspection,
  stepping, and compiled-code sharing across isolated VMs and threads.
- Tests for feasibility results, invalid source, runtime errors, independent
  stacks, and cancellation by dropping suspended execution.
- Rune feasibility report with measured timings, shallow object sizes,
  limitations, and a proposed Phase 1 execution model.

- Initial Rust workspace with the `runa` binary and a `runa-rune` library
  scaffold for Phase 0. Rune integration is not implemented yet.
- Project README and agent guidelines.
- Base directories for architectural decisions, default image scripts,
  development automation, examples, system tests, and the VS Code extension.
- Mise tasks for formatting, Clippy linting, workspace tests, and sequential
  pre-commit validation.
- Tombi, rustfmt, and Clippy configurations.

### Changed

- Expanded the architecture specification with crate ownership and dependency
  boundaries, and moved it to `docs/architecture.md`.
- Required agents to pass `mise run pre-commit` before every commit and document
  user-visible changes in this changelog.
