update with continuation of analysis, prompt 5

> Great! Regarding 'Testing', you are executing on a development machine which has only archiver access. Where testing is needed, please prompt me to perform the needed operations on the instrument, while you observe the response through the archiver. I like your plan to validate by using the archiver data script we developed. Please update the plan to document this. Should we start a new context to execute the plan?

Claude updated the plan per those instructions and suggested a prompt to implement:

Claude updated the plan per those instructions and suggested a prompt to implement (see below).

## Prompt 4

You are working in the tasking project, bl4b-alignment-integration branch. Execute the plan at tasking/plan/refactor-chi-scan-with-flying-callback-technique.md. Create a new branch on the bl4b-scripts submodule off of ScriptScan/2026A, synthesize bl4b-scripts/flying_chi.py per §4–§5 of the plan, and commit. Testing will follow the prompt-and-observe protocol in §6 — do not attempt to run the script yourself.

possible commit 266d6ba84c59517ed6ce057b5b74b087dbed0050

At this point development stalled. It is necessary to re-assess and resume.

## Prompt 5

You are working in the tasking project, bl4b-alignment-integration branch. Some part of the plan at tasking/plan/refactor-chi-scan-with-flying-callback-technique.md was made which targeted the bl4b-scripts submodule, flying_chi branch. It is not clear how far along testing has progressed, so it is best to re-assess. The instrument is not currently available for development as it is in use for a user experiment. Please review the original development proposal at tasking/analysis-chis-scan-integration.md, the code repositories at /home/controls/bl4b/, /home/controls/share/ and /home/controls/common/scantools/issue/4850/ to see how far development has progressed and update the existing tasking/plan files as well as develop new plan files for development that is needed in advance of integration testing at the instrument. There may be an opportunity to do more testing in a couple of days, so the goal of this session is to evalute the code, as well as log files of the active instrument to beome as ready as possible to take advantage of the opportunity. Be resourceful and if there is a tool that you need you may install it according to the instructions of the cross-project knowledge.
