Purpose

Make release failures attributable to a specific check and document the public API migration.

Approach

Separate translation, initialization, physics, signal, FMU and component checks into named workflow steps and retain their reports. Add mirrored-fixture profiling to CI and update the user guide, migration notes and release-readiness documentation.

Validation

Every workflow target and referenced file was checked. Complete numerical regression and rendered-diagram acceptance remain release gates; a green default CI run does not certify a release.

PR CI still does not run most of the new Python tests in this stack. The release gate that does run them is manual and has not run on any review branch. The migration guide gives no modifier map, and BobSim drops unknown keys with no error.

Fixed in three commits: e59f38f runs the release gate on v* tag pushes, and the README now says so. 348aad5 moves the mirrored-fixture profile into its own "OpenModelica Profiles" job with its own 60-minute timeout, so the smoke job has headroom again. 2c6d419 adds an old-to-new map to MIGRATION.md: chassis and axle classes, the template bases, and 17 vcu.* keys that move to driver.*. It also notes that BobSim silently skips unknown keys. I left the chassis stabilizer modifiers out because I could not confirm one new location for every axle type. actionlint is clean. PR CI still does not run make test-additional.
