- set_sample_measured(..., account=...) stores the e-account of the status change in <slot>:MEAS_ACCOUNT; OWNER is no longer filled with the account (owner is free text now). Callers in omny.py/flomni.py pass bec.active_account. The account moves with the sample (transfer_sample) and is reset on load/clear. - OMNY: status 'screened' when a sample leaves the sample stage (stage -> gripper) with status 'none', i.e. no tomoscan was started on it (Mirko 2026-10-27). - widget: shows 'screened'; the P-touch label prints MEAS_ACCOUNT (owner as fallback for older records); CLI views show the account. - IOCs: OMNY ioc_omny.py / flOMNI ioc_flomni.py got the MEAS_ACCOUNT field (and 'screened' appended to the OMNY status enum), deployed on mpc3217 / mpc2844. - tests/e2e harness updated (owner_if_empty replaced by account).
