Summary

  • DATA-9 and DATA-10 settled by direct read against the live 2bmb deployment on 2026-08-11: git diff of the deployed tomoscan checkout, content of the deployed areaDetector layout XML, and a live caget of the timestamp PV. Rows deleted per this page's own confirmed-item convention; evidence recorded in Operations.
  • DATA-8 stays open: found a real dropped-frame instance (a smoke-test file with theta absent), confirming DataExchangeScanReader's designed handling, but the frequency question for production scans is unanswered.
  • HOST-1/HOST-2 gain concrete values found on the beamline (arcturus's actual EPICS_CA_ADDR_LIST; the real file location is /local2, not /local1), plus a note that whether CORA's host inherits them is being asked of the beamline contact.
  • New HOST-6: which host should CORA actually run on, prompted by finding a pre-staged, empty cora conda env on tomdet.
  • Corrected Operations' storage-pipeline paragraph from /local1 to /local2, per a direct read of the live DetectorTopDir PV.

Test plan

  • mkdocs build --strict (CI's exact dep pins) — same 7 pre-existing warnings as main, all in files this change doesn't touch (contributing.md/security.md/run.md/talks.md); no new warnings
  • Read the full diff end-to-end for internal consistency after fixing a mid-review mistake (see below)

Note: an earlier draft of this change marked DATA-9/DATA-10 Already done? = yes instead of deleting the rows — caught against this page's own documented convention ("confirmed items get the row deleted") before commit and corrected.

DATA-9 and DATA-10 are settled by direct read against the live 2bmb
deployment on 2026-08-11 (git diff of the deployed tomoscan checkout,
content of the deployed areaDetector layout XML, a live caget of the
timestamp PV), so their rows are deleted per this page's own
confirmed-item convention and the evidence recorded in Operations.

DATA-8 stays open: a real dropped-frame instance was found (a smoke
test with theta absent), confirming the reader's designed handling,
but the frequency question for production scans is unanswered.

HOST-1/HOST-2 gain the concrete values found (arcturus's actual
EPICS_CA_ADDR_LIST; the real file location, /local2 not /local1) and
a note that whether CORA's host inherits them is asked of Francesco.
New HOST-6 asks which host CORA should actually run on, prompted by
finding a pre-staged, empty `cora` conda env on tomdet.

Operations' storage-pipeline paragraph is corrected from /local1 to
/local2, per a direct read of the live DetectorTopDir PV.
