General items and discussion:
RTT counts are still down (waiting for Nick to be back and fix).
Migration from Savannah to Jira seems to be slowly digested by validation contacts: the email notification system could be improved to help everyone quickly distinguishing among more or less relevant messages.
Now that we have 19.1.1.3 samples with trigger, we should get our validation machinery work: all signature groups should provide feedback (very) soon, especially those not present at today's meeting.
In few days, if T1 sample available, a dump of DC14 trigger counts may be available on a webpage by Roger for a comparison among the tags to be validated.
One main point to be considered concerns memory leaks, especially if >100kB/event. 
After the July-August shift, Andrea will be substituted by Fabrizio (September-October) as rotating validation coordinator.

Some (partial) details on slices.
Muons (Antonio+Andrea): ATN/RTT no muon related problems. A new memory leaks was fixed, other leaks from offline. Urgent deliverables OK and updated; L2 objects in EDM should be ready soon. PhysVal checks have been done on rel19 tags provided by Carl: no big issues found and reasonable comparison concerning efficiency and resolution plots. As expected, rel17 samples are unreadable with EventLoop (but there must be some way to convert old AODs in the xAOD format, since people will still be interested in doing their analysis on old 2011 data).
b-jets (Merve): ATN/RTT all problems are common with other slices. At the moment there are 5 bugs, out of which ATR-8893 (mem leak) and ATR-8948 (FPE) are relevant; ATR-8093 reassigned to ID. Large memory leaks under investigation (>200kB/event). Readiness for DC14 in good shape. No news on PhysVal samples (planning to use RootCore code).
Jets (Sebastien): ATN/RTT mostly OK, except for JetSliceAthenaTrigRDO, and also AthenaTrigESD_HLTMonitoring always crashes: trying to understand. No big improvements on bugs (ongoing migration to xAOD::EventInfo). Memory leaks maybe due to vector allocation? (hard to tell). TrigJetMonitoring working for PhysVal purposes, but still no look at rel19 samples. 
Tau (Samina): Bugs are 4, most relevant are ATR-8208 and ATR-7958. Huge memory leaks for 19.1.X.Y-VAL: a new bug to be opened for thema and after looking at LeakCheck.txt. DC14 deliverables OK. No news on PhysVal samples, but Tau slice is focusing on it.
BPhysics (James): no obvious issues on ATN/RTT (expect for the known problem of zero counts). One relevant bug open (ATR-8908) on a crash accessing variables. Quick look at memory leaks, possible issue found but maybe due to HLT::NavigationCore. DC14 readiness mostly OK, finalization on few algorithms to be completed. PhysVal on Z->mumu rel19 samples (rel17 unreadable), but will have to check on other samples which could be more relevant for B-physics; HLTMonitoring code updates expect to resume soon.

Missing slices: Egamma, MET, MinBias, Calo, ID (urgently waiting for their feedback: please upload in the agenda!).
