The flOMNI sample storage moves from the XOMNY-SAMPLE_DB_flomni:GET/.DESC
records (name and owner packed into one 40-char DESC via sample_desc_codec,
measurement status in the BEC global var "flomni_measured_samples" keyed by
that packed string) to one record per slot on the flOMNI soft IOC
(flOMNI repo, softioc/ioc_flomni.py):

FLOMNI-SAMPLE:<slot>:USED / NAME (up to 256 chars) / OWNER /
                     STATUS (none|started|completed) / MEAS_DATE
<slot> = STAGE (0), T01..T20 (1-20), GRIPPER (100)

No transition (decided by Mirko 2026-10-17).

  • FlomniSampleStorage: same public methods (slot 100 = gripper), attribute
    names sample_placed/sample_names/sample_in_gripper[_name] kept; new
    sample_owners/sample_status/sample_meas_date (+ gripper equivalents),
    get_sample_status/meas_date/record, set_sample_measured(slot, status,
    date, owner_if_empty) and transfer_sample(from, to), which moves the whole
    record so the measurement status travels with the sample
  • flomni plugin: transfers use transfer_sample(); tomo_scan marks the stage
    sample started/completed on the record; the label offer reads status,
    date and owner from the record; _MeasuredSampleLog and
    sample_get_measured_log_key removed
    Behaviour change: the label's account is the sample owner (was the active
    account at measurement time); set_sample_measured fills an empty owner
    with the active account
  • sample storage widget: bulk read incl. owner/status, writes via
    set_sample_slot/unset_sample_slot; no global-var measured log
  • webpage generator: name and owner from separate fields
  • e2e harness and tomo test updated; nexus writer unchanged (sample name is
    now the plain name)

Tested against the live IOC on mpc2844 (ophyd): long names, transfers slot ->
gripper -> stage with status/date, owner_if_empty, show_all, clear, slot
range check, bulk read() keys.
