I have removed the test introduced in #39 because it doesn't work due to some geometry issues. |

changed the title
It looks like using only one event and EvtMax=-1 hides failures somehow
New seeded CKF tracking algorithm that is entirely independent from ACTSAlgBase. Obtains tracking geometry, magnetic field, and cellID→surface mapping directly from IActsGeoSvc instead of building its own geometry from TGeo files. - CKFTracking.hxx: reusable helpers parseSeedingLayers() and makeInitialCovariance() extracted from the existing algorithm - CKFTrackingAlg.cpp: self-contained algorithm using ActsGeoSvc; default-constructs GeometryContext, MagneticFieldContext, CalibrationContext as required by the ACTS framework - Helpers: accept shared_ptr<const MagneticFieldProvider> so both algorithms (const and non-const field pointers) can use the helper - CMakeLists: register CKFTrackingAlg.cpp as a plugin source Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Adds an options file and CTest entry for the new CKFTrackingAlg that uses ActsGeoSvc (Blueprint-based geometry) instead of algorithm-level TGeo file loading. The test runs on the same simulated MAIA data as the existing reco_MAIA test and verifies that the algorithm initialises and processes hits without crashing. SeedingLayers is left empty pending geometry-ID inspection of the Gen3 path; the test exercises the hit-conversion pipeline and CKF setup even without seeds.

The required tests are finally behaving, so I'd plan to merge this PR tomorrow |

[ ] Includes [WIP] Add a simple runtime test #39This is a first version of a CKF (largely copied from the existing one) for running tracking. It works for
MAIA_v0and should largely be seen as a proof of concept for now. Things that will (almost certainly) be out of scope for this PR:Things that I would still like to tackle:
