layout: plain_toc

Present/Contributing: Caterina Doglioni, Ruslan Mashinistov, Claire Antel, Joshua Isaacson, Eduardo Rodrigues, Saptaparna Battacharya, Michel Hernandez Villanueva, Peter Fackeldey

Apologies/Contributing: Graeme Stewart, Liz Sexton-Kennedy, Christian Wessel, Maarten van Veghel, Alexander Moreno, Stefan Roiser

Two proposals relevant for HSF:

- PSENTRIC (HORIZON-INFRA-2026-DEV-01-02), follow-up of ESCAPE (<https://projectescape.eu/>) and including a broader astronomy community and analytical physics facilities (Caterina Doglioni and Graeme Stewart as contacts)

- OSCARS2 (HORIZON-INFRA-2026-01-EOSC-01), follow up of OSCARS (<https://oscars-project.eu/science-clusters>) with HSF involvement for training and affiliated project guidelines (Stefan Roiser and Caterina Doglioni as contacts)

One letter of support for HORIZON-INFRA-2026-TECH-01-01 circulated on HSF Forum mailing list last week.

- Co-organising the next **WLCG/HSF Workshop**, 2-6 November 2026 in Bologna: Converged on draft schedule of HSF parallel sessions.

- Anticipate a call for contributions!

- We are still (for a bit) looking for conveners for the HSF parallel sessions. Please get in touch (very soon) with the SG if you're interested.

Plan for the near future:

- online agenda version by the end of the month

- finalising the conveners - we will send specific invitations, open a call for abstracts as well at the beginning of July

- coordination with WLCG on environmental sustainability needed (Caterina/Eduardo will follow up).

The ePIC collaboration is now part of the advisory group.

Status at <https://hepsoftwarefoundation.org/projects/projects.html> - **6** projects affiliated.

Reviews in progress, being finalised:

- NoPayloadDB Conditions Database

Status: reviewers busy, but no other showstoppers identified so far.

Other potential projects:

- ACTS: Caterina will email the SG to find out who is already in contact

- Herwig (we already have Madgraph/Pythia) - we will hear from Christian Gutschow and James Whitehead (MCNet reps).

- Phoenix - the author is happy to join, the SG will look for reviewers

- Rivet - Caterina will follow up with authors next week

SG will find volunteers to contact these projects from GSoC list of projects this year:

- Clad

- Omnifold (Saptaparna will contact authors)

- PODIO (future collider frameworks - Michel will contact authors)

Do not hesitate to discuss around you to identify relevant projects/libraries that could engage with the affiliation programme. AA conveners are in an excellent position to help us identify which projects to prioritise to join the affiliation programme.

*Feedback still welcome:* So far HSF repositories do not provide any statement on AI-powered/-helped contributions, and we are starting to get some. On occasions we can be flooded by not-to-useful contributions.

This year an "AI statement" is strongly suggested in GSoC proposals. We should do something similar.

There is an ongoing discussion at <https://github.com/HSF/hsf.github.io/issues/1919>.

**Q: Should we think of a code of conduct/guidelines?**

Suggestion to update the [website how-to](https://hepsoftwarefoundation.org/howto-website.html) with a statement on AI and how we will be dealing with "spam".

Following the LHCC recommendation (from [previous minutes](https://hepsoftwarefoundation.org/organization/2026/06/04/coordination.html)):

_[The LHCC] Encourages the HSF to continue the open discussion around AI and AI-assisted technologies and to develop a policy framework for their application within HEP software. Additionally, it recommends that the HSF assumes a leading role in the coordination of training initiatives focused on these new technologies._

Decision taken to start a public discussion towards (1) loose guidelines on AI-assisted coding in common software (2) common training that collaborations can build on.

Plan, to be taken on by Claire, Michel, Caterina:

- have an HSF meeting on July 29th, 15:30-17:30

- send a "save the date" co-organise the meeting with anyone else interested in the topic, namely [EuCAIF Fair & Sustainable WG](https://eucaif.org/activities/), [Interexperiment ML working group at CERN](https://iml.web.cern.ch/), [EVERSE project](https://everse.software/) and [RSQKit](https://everse.software/RSQKit/), [“Towards a National-Scale AI Collaboration in HEP” US blueprint workshop](https://indico.flatironinstitute.org/event/4120/).

- discuss the plan for the meeting with the SG via e-mail the week of 22.06 before sending the announcement

Points and links raised during the discussion in the coordination meeting:

- Michel: Belle2 would be interested in the HSF being the contact point for responsible use of AI.

- Claire: "using LLM" tutorials in ATLAS don't feature responsible use of AI, but there are [slides from IRIS-HEP]( https://indico.cern.ch/event/1686249/contributions/7130122/attachments/3294175/5891009/LLM101-IRISHEP.pdf)

- Michel: training events in BNL asked for best practices in use of AI, and we put some slides together based on experiences: [AI-assisted code, Remarks & discussion on best practices](https://indico.cern.ch/event/1683420/timetable/#b-670574-remarks-on-ai-assiste)

- Caterina: the research software community has been thinking about this, see e.g. <http://arxiv.org/abs/2510.22254> and <https://doi.org/10.5281/zenodo.20321134>. There are also CERN guidelines <https://home.cern/general-principles-use-ai-cern/>

Planned HSF seminars:

- [24th June (next week)](https://indico.cern.ch/event/1692605/): Seminar on Software Packaging - organised by Software Tools & Packaging AA.

Do not hesitate to get in touch with the SG if you have/know of events useful to add to the HSF calendar.

The calendar is used by very many to check for available dates, constraints, and plan events. Thank you in advance.

Sapta has a poster to promote the HSF. There is one version [here](https://indico.cern.ch/event/1606598/), but please contact her for the latest version.

There is now an early "proof of concept" version: [hep-constants](https://github.com/HSF/hep-constants). Some generally positive feedback was received, but no further development yet.

The next coordination meeting will be on July 2nd.
