Hello!

## History

Review the session log in the ai/ folder for prior context.  Some additional work was done outside AI sessions we well.

Please look at this script: trim_excess_metadata.sh

## TO DO FOR THIS SESSION

My asks for this session:

* Review the file 'SampleUserError.txt', which contains a snippet of the log from a production run in the customer's environment.  It was failing to delete users (problem 1), and then its ticket expired while running and everything started failing (problem 2).  I put in mitigations for both.
* Review the change I just made to fix these issues, in trim_excess_metadata.sh#32 (change @73).
* For this session, ignore the plans to address future limitiations and focus only on reviewing the change I made, and let me know if this should fix the issue.  There were 2 changes, a bug fix and a feature squeeze into #32, which the script knows itself to be version 3.1.4. Review both the bug fix and the feature to add a sfety check for a long-duration ticket.

The lab environment environment has recently been reset to Lab 0 state.

## Version Control

You're working with P4 in a private repo cloned from a path on the Public Depot (using P4-native DVCS features).

The workspace root is /home/perforce/tem:

The private repo was created something like this:
    mkdir /home/perforce/tem
    cd /home/perforce/tem
    export P4CONFIG=.p4config.local
    p4 -u tom_tyler -p public.perforce.com:1666 login
    p4 -u tom_tyler clone -p public.perforce.com:1666 -f //guest/tom_tyler/sw/main/tem/...
    ln -s ai/AGENTS.md copilot-instructions.md

TIP: The ai/ folder is versioned, but the symlink 'copilot-instructions.md' that points to ai/AGENTS.md is not versioned.

As a agent working in this area, to get setup for versioning, you'll do this at the start of each session:

    cd /home/perforce/tem
    export P4CONFIG=.p4config.local
    p4 opened # Ask Tom about any opened files.
    p4 fetch # Pull latest version from the Public Depot to our private local repo.

Changes may have been made outside AI sessions, and thus not reflected in the session logs. Be sure you have the latest version before starting work by doing a 'p4 fetch' to pull files from the public server as noted above.  Review the history of files and changes if/as needed, e.g. with `p4 filelog`, `p4 changes`, `p4 annotate`, etc.

## Lab Environment

If you see that you are on the server machine p4c-bos-01, that means you are in the P4 Battle School Workshop Lab Environment.

To interact with that P4D server there, can simply unset the P4CONFIG shell environment variable.  Then the P4PORT and other settings will target the local p4d server.

This server has a training data set installed.  Because the very nature of the trim_excess_metadata.sh script is very destructive to P4 data, we're using the Battle School Workshop because the data can be reset back to a baseline data set for iteractive testing of our script.  We can also make changes if needed before running the test, e.g. adding server or remote specs that may not be in the standard training data set that the lab resest to.

Ask Tom when the Lab Environment needs to be reset.  When the lab gets reset, the /home/perforce/tem folder is unaffected.  However, any of the P4 data in locations like /p4/1/root get reset back to a baseline during a reset. This is generally as desired, but one needs to be aware of what data is lost (by design) before requesting a lab reset.
