## Round The Table

#### Carsten

* Found some files in the dirac-filecatalog
* ILD Mass Production Generator Sample description website:
   * Leonhard: looks like this is not as easily available as I thought... There is
       * https://ilcsoft.desy.de/dbd/generated/other.html
     Which for e.g. 4 fermions includes [all the nice stuff I talked about](https://ilcsoft.desy.de/dbd/generated/250/4f_production/singleW/semileptonic/whizard-channels.sw_sl0qq.pdf) but not for Higgs. And everything is still from the dbd and a bit outdated...
* ilcdirac-doc https://ilcdirac-doc.web.cern.ch/
   * particularly https://ilcdirac-doc.web.cern.ch/DOC/Files/UserGuide/examplejobs.html#marlin

#### Swathi

* LAr ECal barrel endcap, barrel was too long by factor of 2, no more overlaps between barrel and endcap
* Overlap between HCal Barrel (was moved outward) and Solenoid by 40cm, HCal Barrel is 1.1 m deep
   * Shrink HCal for the moment, eventually re-arrange outer detectors
   * Re-open PR for k4Geo
* Investigating Pandora Processor

#### Juan

* [ ] Setting up buildcache
   * One of the nightlies added to buildcache, took 3 or 4 hours
       * Also makes packages relocatable
   * Installation was missing keys used to sign the packages, installing did not work

* [x] Issue with downstream build action: https://github.com/key4hep/key4hep-actions
   * Complicated to make spack use upstream packages, instead of re-compiling the same commits

* [ ] spack develop documentation update for latest

* [ ] RNTuple for podio
   * Received comments from Jakob B.

* Key4hep Stack
   * LD_LIBRARY_PATH not present by default, added to places where this was missing, could still be missing in some places
   * llvm added, but this added compiler variables, order of compiler selection changed
   * patch dd4hep: https://github.com/key4hep/key4hep-spack/issues/487

* Validation Workflows
   * Script to be uploaded
   * https://key4hep-validation.web.cern.ch/
   * Source code on github:

#### Andre

* FCC Vertex/Tracker Integration note: https://www.overleaf.com/read/tpssnxzwkwmk

#### Leonhard

* CLD Reco
   * [ ] CLDConfig Repository
   * [ ] Save history from ClicPerformance of FCCConfig
