v0.2.27: embed runtime into the core application
This tag captures the migration of Simprint Runtime back into the main application, together with browser startup reliability improvements and a local update-bypass option after v0.2.26.
Changes included:
- Added the runtime crate under src-tauri/crates/runtime and replaced the standalone runtime process boundary with an in-process RuntimeHost integration.
- Removed the separate runtime executable updater, sidecar packaging, build hooks, release metadata, and CI references that were no longer needed after the migration.
- Added bounded EventBus handshake and CDP readiness checks so browser launches no longer remain indefinitely in the Starting state when the kernel does not become ready.
- Detects early browser-process exits, preserves Error states instead of overwriting them with Stopped, and redirects browser output to simprint-browser.log for diagnosis.
- Added the --skip-update startup argument at the automatic-update entry point, allowing local testing to bypass update checks without passing the option into updater internals.
- Updated runtime bridging, configuration validation, documentation, and regression tests for the embedded architecture.
Migration note:
- The standalone Simprint/simprint-runtime repository is deprecated. Runtime development now continues in src-tauri/crates/runtime within the main Simprint repository.
Expected result:
- Contributors can build and debug Simprint without separately obtaining or packaging a runtime executable.
- Browser startup failures now produce bounded, actionable errors and dedicated browser logs instead of leaving environments stuck in Starting.
- Developers can run local production-feature tests with --skip-update while the normal release update flow remains unchanged.
