## Round The Table

#### Carsten

* Samples were not centrally produced, are only somewhere on KEK-CC

#### Swathi

* All major overlaps removed from the CLD_LAr detector
   * PR: 
   * Shared steering file with Brieuc
   * Link to the PR with the steering:https://github.com/BrieucF/LAr_scripts/pull/12
* Creating Steering file to run Pandora
 

#### Juan
* Validation:
   * Workflow ready, ran it but there are issues with matplotlib (introduced when llvm was added to the build)
   * Building from scratch a new nightly to fix this issue
   * Plan to ssh to a machine with eos (lxplus, for example) to put the plots on eos for now until eos is mounted on the instances
       * CI example to publish EOS: https://gitlab.cern.ch/ci-tools/ci-web-deployer
* Build cache:
   * Code to push and fetch added to gitlab CI
   * Last build from scratch (2023-05-20) was pushed for CentOS 7, AlmaLinux 9 and Ubuntu
   * New build is (will be) using the build cache for package fetching
   * Packages are not signed but only I and owners of the gitlab repo have access to the secrets to publish
   * It seems that pushing and fetching from multiple nodes at the same time works fine
* Documentation
   * Some documentation in the README of the key4hep-spack repo: https://github.com/key4hep/key4hep-spack/blob/release/README.md
   * More documentation in key4hep-doc but no PR yet
* RNTuple for podio
   * Writer updated 
* Key4hep Stack
   * Several of the recent PRs to spack have been merged so the new build has some customizations removed
   * Patch for dd4hep 1.23 merged upstream

#### Andre

* FCC Vertex/Tracker Integration note: https://www.overleaf.com/read/tpssnxzwkwmk
* FCCDetectors vs lcgeo FCC_o2_v2/3 investigations

#### Leonhard

* Slides: 
   * See also: https://github.com/Zehvogel/enuW/blob/master/e.ipynb
* Plots needs units
* Which sample was used? Polarisation? only electrons (or muons as well)?

#### Jenny

* ECFA Reconstruction Workshop July 11--12 is open
* ECFA Paestum Workshop, October 11--13, is also open

## TODO

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

- [ ] sign up for iLCDirac: https://ilcdirac-doc.web.cern.ch/
   - [x] Leonhard
   - [x] Juan
   - [ ] Swathi
   - [x] Carsten
   - [ ] Jenny

- [ ] Point to files on EOS: qqbar, maybe muon input files (Andre)
   - [x] Add people to eos-egroup
   - /eos/experiment/clicdp/grid/ilc/prod/clic/`ENERGY`/`EventType`

- [ ] Need k4FWCore with Frame Reader

- [ ] add k4Geo environment variable to eventually replace LCGEO env var
