Assistant: ask the site, and keep the thread

The bubble on every page and the same assistant as a whole page at /agent/<slug>, 22 ก.ย. It plans, calls read-only tools over the project's own data (the graph, the citation registry, the station values, the mechanical rows, the failure modes, the board, and a search over the team's documents), then answers. Every citation key is checked against the registry and against what the tools actually returned this turn, and a number that appears in neither is flagged. A conversation gets its own link, so it can be handed to someone who reads the thread and asks the next question. Typhoon, Thai or English, not medical advice.

Design 1 update: size, pressure and the rotor sensor

27 ก.ย., for the design 1 and 2 session that night and the Final design meeting on 29 ก.ย.: the two design 1 tasks from the meet sum doc answered with computed numbers (impeller and chamber size against speed and room, port and vessel Reynolds numbers against Ton's own limits, the loss where a port meets its vessel, where the Hall sensors go on the stator), Ton's acceptance test scored on C1 to C5, and what Design 2 still owes. 28 ก.ย.: C5, the layout the team chose on the 27th (two sealed chambers, one stator in the wall, two rotors), in full detail. Thai, every number with its status.

C5 readiness panel: what is missing, by system and stage

1 ต.ค.: an overhead panel of 86 push-buttons, one per thing C5 needs, rows by system (whole heart, P1 to P7, the regulatory file), columns Constraint, Design, Simulation, Mock, then the later electrical, animal and clinical stages of the team's ISO 14708-5 roadmap. Every light computed from the files (design/c5_panel.py); press a button for the evidence, the owner and what lights it, and record the team's own state beside it (drop password).

C5 drawing set and spec sheet

29 ก.ย.: one hidden line drawing per part (four views, overall dimensions) projected from the built C5 solids, the bill of materials with the count of pieces, the assembly order, a first pass at the two windings (turns, wire, current, copper loss at the assumed flux), the performance the layout reaches as a TAH (head against speed, power, Reynolds at the ports) and every constraint check with its verdict. Thai, every number computed, SVGs downloadable.

C5 on its own path: work packages and the fit at every interface

28 ก.ย.: the layout the team chose on the 27th, split into eight work packages (housing, the stator wall, each rotor, the ports, the controller, the lining, the loss model) so each can be given to one person: the parts, the numbers two packages hand each other, the deliverable, and the owner. /public/c5-model shows C5 alone in 3D, exploded and built step by step. Owners are filled in design/c5_tasks.json.

Candidate pump bodies, C1 to C5, for Shapr3D

23 ก.ย., for LN and the 27 ก.ย. design meeting: LN's page 3 layout (C1), Concept A's single disc (C2) and two separate pumps (C3), drawn as solids in the CT heart and answering Ton's six questions each: the frame the ventricles leave (about 576 cm3, 134 x 111 x 95 mm), where the rotor sits, radius against speed, coils and vanes, watts, materials. 27 ก.ย.: C4 (axial + centrifugal) and C5, the layout the team chose that night: two sealed chambers, one stator in the dividing wall with a winding on each face, two rotors held against it on a thrust film and a ceramic pivot, no shunt, balance by two speeds. STEP files that open in Shapr3D in /dropin/design/, models C1 to C5 on /public/cad, every number with its status in design/OPTIONS.md. A design exploration, not a device.

Implantation, step by step, on the CT heart

/public/implant, 22 ก.ย.: the surgical group's Draft 6 sequence, eleven steps from sternotomy to closure, played as a walkthrough on the same CT heart and the same BiVACOR geometry as /public/cad: the ventricles leave, the atria and the four valve rings stay, the cuffs go on, the device slides in along its own port axis to the docked pose, the streams start, the skin closes. Every card keyed to the papers the group cites (surgery/SURGERY-DRAFT6-2026-09-22.md); what is not on file (bone, cannulae, sutures) is said, not drawn.

Blood and the design: which lever moves which damage

/public/blood, 21 ก.ย.: the team's hemocompatibility draft (high shear, stagnation, recirculation, separation) mapped onto the drawing, laid out like /public/cad: the section fills the stage, levers in a side panel, one zone's detail in the inspector, the rest behind a Data drawer. Nine sliders recolour the section by risk and report tip shear against the 10, 50 and 150 Pa lines, passage Reynolds number, residence time and recirculation read off the measured low-flow pump, and inlet incidence, with the head each setting still makes against the duty. A matrix of mechanism against lever with every sourced cell, and Mahidol's CFD haemolysis beside the built device's measurement. Order estimates for ranking a change, not a CFD.

Trio's rows, keyed 21 ก.ย.: read them against your own tables

Trio sent her three quests as documents rather than through the form, so her rows were keyed on Ton's side into trio/TRIO-T1-T3-2026-09-21.md (short TRI in nont_tables.py) and the pages quote that file directly. Nothing to re-key. Non's part: where her rows overlap his (right atrial and pulmonary artery pressures, the aortic diameters), check the two agree and say so in his file; and take the model order about the lungs if she sends one in LINE. Her 17 unsourced rows go back to her, never in as ASSUMED.

Arrived as two documents in chat (Heart_Hack.docx: T1 and T2 as tables for all nine stations; Task 3 summarized.pdf: T3 with ten sources). Every citation was resolved before it was keyed: 27 of 44 T1 rows and 22 of 31 T2 rows carry a source that resolves, all 10 T3 sources do. Three citations corrected from the record (first author, journal, a missing DOI). Now quoted on /public/heart, /public/cad and the gap map. Held back as questions to Trio: the filling pressures and valve gradients, everything at the pulmonary veins, the LA pressure, the MAP range, one textbook with no edition or page.

29 ก.ย., the chair's summary: everyone in Design finds and shares WPT ideas, the information so far is thin. On file: Concept A's chain (13.5 V supercapacitor bus, about 10 W into the skin at rest for C5) rests on a 0.70 link efficiency with no source, and Mahidol measured severe loss through 30 mm of pork.

The blood path, station by station

/public/heart: the CT heart in 3D with blood tracing the path from the venae cavae to the aorta. Tap a station for what it is, the normal values it must meet with their sources, the same values for a person of a given age, sex, height and weight, and a place to add a value with its citation. Works on a phone; each addition becomes a file in /dropin/trio/ that Non keys in.
