Open questions¶

What CORA needs the MANACA team to confirm before the model can be trusted.

MANACA was reverse-engineered from Sirius's public facility pages (lnls.cnpem.br/facilities/manaca) and a verified research brief, not from a live connection. LNLS publishes its control software (the Bluesky-based sophys family) openly, but no per-beamline EPICS PV manifest, so the Inventory is a planned shape with control handles unbound. MANACA is Sirius's first macromolecular-crystallography beamline, CORA's second modelled Sirius beamline after the MOGNO tomography scaffold. Each row below is a fact the beamline team owns, not a CORA modelling choice (those are on Model). It is a delete-on-answer queue. Priorities are Blocks-build, Blocks-go-live, and Nice-to-have.

Topology and scope¶

ID	Priority	Question	CORA assumes	Resolves
ENC-1	Blocks-go-live	The hutch grouping: a shared optics hutch feeding one experiment hutch, or a different layout?	A `manaca-optics` zone and a `manaca-experiment` hutch.	The Enclosure grouping.
SRC-1	Nice-to-have	The undulator period and parameters.	An undulator source, 5-20 keV; period pending.	The source Asset detail.

Source and optics¶

ID	Priority	Question	CORA assumes	Resolves
MACHINE-1	Nice-to-have	The Sirius storage-ring state MANACA reads.	Observe-only machine state, a loose `StorageRing`; exact handles pending.	The machine-state observation.
MONO-1	Blocks-go-live	The monochromator crystal / multilayer type and handles.	A monochromator bound to `Monochromator`; 5-20 keV.	The monochromator modelling.
ENERGY-1	Nice-to-have	Whether energy is scanned as the measurement (anomalous MX).	A master energy `PseudoAxis` the monochromator tracks.	The energy-axis modelling.
FILT-1	Nice-to-have	The attenuator / transmission foil set.	An attenuator unit bound to `Filter`.	The attenuator Asset detail.
OPT-1	Nice-to-have	The focusing mirrors and beam-defining slits (presence, handles).	No standalone mirror / slit device published; deferred.	The optics Asset detail.

Sample endstation¶

ID	Priority	Question	CORA assumes	Resolves
GONIO-1	Blocks-go-live	The goniometer geometry: the rotation, centring, and alignment axes.	A `Goniometer` (the graduated i03 family); axis set pending.	The goniometer modelling.
TEMP-1	Nice-to-have	The cryostream sample-cooling sensor and setpoint handles.	A `TemperatureController` (the graduated family).	The temperature-control modelling.
SAMPLE-1	Nice-to-have	The beamstop axes and the sample-environment detail.	A `BeamStop` at the sample; axis set pending.	The sample-stage modelling.
ROBOT-1	Blocks-go-live	The automated 48-pin sample changer (load / centre / collect / unmount loop).	A deferred sample-exchange Procedure over the spine + a Subject custody thread, not a device family.	The sample-exchange modelling.

The detector¶

ID	Priority	Question	CORA assumes	Resolves
DET-1	Blocks-go-live	The area-detector model (a Pilatus / Eiger-class photon-counting detector), its translation stage, and the on-axis camera.	A `Camera` plus a `LinearStage` and an on-axis `Camera`; model not published, carried pending.	The detector modelling.
DIAG-1	Nice-to-have	The incident-flux monitor handles.	A `FluxMonitor` (the graduated family).	The flux-monitor modelling.

Control and safety¶

ID	Priority	Question	CORA assumes	Resolves
CTRL-1	Blocks-go-live	The EPICS PV and MXCuBE device handles per MANACA device (absent from any public per-beamline manifest).	The handles are unbound, carried pending; the control plane is the Sirius EPICS floor + MXCuBE3.	Binding each Asset's control handle.
ORCH-1	Nice-to-have	Does MANACA run the Bluesky / Ophyd (sophys) orchestration layer, or another scan engine under MXCuBE?	Bluesky / sophys is a named facility direction (as MOGNO records); the MANACA status is unconfirmed.	The orchestration-layer modelling.
PSS-1	Blocks-go-live	The Sirius personnel-safety permit signals and the photon / front-end shutters (not published per beamline).	Permit leaves and shutters to be named; not invented here.	The Enclosure permit signals and the safety tier.
SUP-1	Nice-to-have	The vacuum extent and the cryostream liquid-nitrogen / beam supplies.	Photon beam, cooling water, vacuum, and liquid nitrogen.	The Supply observations.
GOV-1	Nice-to-have	The Sirius operator pool and safety-review structure (site-level).	Carried pending on the Sirius Site, not instantiated per beamline.	The governance principals.

Technique¶

ID	Priority	Question	CORA assumes	Resolves
TECH-1	Nice-to-have	Do rotation MX and grid scan enter CORA's catalog as Capabilities / Methods?	Deferred: carried as pending Practices reusing the i03 `mx_data_collection` and `grid_scan` slugs; none coined.	The technique Capabilities.
