  "role": "Mechanical integration, clearances and BOM interfaces — worker-a; bounded to workstation-dimensions and the mechanical contribution to workstation-question",
  "findings": [
    "Investigation references are exactly workstation-question, workstation-dimensions and workstation-concept, each at contentRevision 1. Their supplied origins are human and their evidence statuses are unassessed. The mechanical contract is supplied design data, not measured geometry; workstation-concept is a candidate interface idea.",
    "Coordinate basis: mm; X width, Y depth, Z up; origin at the base lower-front-left. The base occupies nominal X0–540, Y0–420, Z0–12. The deck minimum [140,50,56] and size [260,200,8] put its nominal underside at Z56. A standoff of supplied height 44 would span the difference from the base top at Z12, but its mounting and deck attachment are unspecified.",
    "The Y rail centres are X70 and X470, with rails running Y30–390. The bridge minimum [50,180,310] and size [440,60,30] place its nominal X extent across both rail centres and its Y midpoint at the supplied gantry centre Y210. Rail-to-carriage, carriage-to-saddle, saddle-to-tower and tower-to-bridge attachments remain undefined; carriage spacing does not define motion endpoints.",
    "The X rail runs nominally X65–475 at front Y164 and minimum Z318. Its proposed travel is 300 mm, not a defined endpoint pair or demonstrated stroke. The X carriage, X screw and focus backplate need specified attachment faces and moving-versus-fixed assignments. The Z rods have supplied length 120 mm; the proposed 30 mm focus travel likewise has no endpoint definition.",
    "Functional subassemblies, not additional LIGHT modules: SA01 base/feet; SA02 Y guidance/carriages; SA03 gantry; SA04 X guidance/carriage/screw; SA05 Z guidance/screw; SA06 optics envelopes; SA07 deck/workholding; SA08 enclosure; SA09 controller housing; SA10 cable carrier. Proposed stable part-ID crosswalk: P01 base; P02 Y rail; P03 Y carriage; P04 Y saddle; P05 gantry tower; P06 bridge; P07 X rail; P08 X carriage; P09 X screw; P10 focus backplate; P11 focus rod; P12 focus screw; P13 camera-body envelope; P14 lens envelope; P15 ring-light envelope; P16 deck; P17 standoff; P18 rear panel; P19 side panel; P20 controller housing; P21 controller lid; P22 carrier link; P23 foot. These are identifiers for supplied elements, not a claim that every element is a separately manufactured component.",
    "Provisional BOM quantities supported by explicit counts or singular named elements: P01 1, P02 2, P06 1, P07 1, P08 1, P09 1, P10 1, P11 2, P12 1, P13–P16 1 each, P17 4, P18 1, P20 1, P21 1, P22 12 and P23 4. P03–P05 and P19 quantities remain unresolved; count no vent as a separate part merely because ventCount is 8. Mounts, fasteners, workholding fixtures, motors, bearings and connectors have no supplied BOM specification or supported quantity. Purchased-component shapes are nominal envelopes, not vendor-qualified selections.",
    "Exactly three named LIGHT modules, with exactly two proposed acceptance-question slots each: base and motion structure — (1) assembly/interface review: are the named rail, carriage, gantry, X and Z interfaces identified? (2) manual positioning/clearance review: are declared positions and unresolved endpoints distinguishable from checked clearances?; workholding/optics/enclosure interfaces — (1) fixture/optics setup review: do deck reference and optics envelope agree with the declared setup? (2) enclosure/cable/service access review: are panel, controller and carrier access questions recorded?; local staff inspection record and service handoff — (1) record/setup-reference review: do references match the staff-declared setup? (2) handoff reconciliation review: can staff identify and resolve stale or incomplete records? These are slots and questions, not full stories or evidence.",
    "Proposed worker-b setup-reference manifest M-SETUP-r1: contract identity tce-cookbook-mechanical-design-v1 / inspection-workstation, locked parameters unchanged; the three node IDs at revision 1; SA01–SA10 and P01–P23 crosswalk above; fixture reference FX-DECK-GRID-r1, meaning a proposed reference to P16's supplied grid rather than an added fixture; synthetic inspection ID; explicitly staff-declared manual X, gantry-Y and focus-Z setup state without inferred coordinates; and flags for unresolved endpoints, mounting, optics overlap, enclosure access and carrier route. Worker-b owns the record fields and synthetic inspection-ID assignment; staff declare physical setup changes, reconcile mismatches and acknowledge handoff. M-SETUP-r1 is a proposed manifest revision, not a revision of the locked contract.",
    "Proposed later evidence requests to the separate geometry builder: identified assembly, exploded and relevant section views; source-linked image references IMG-ASM, IMG-EXP and IMG-SEC with builder as future owner and all three marked pending; actual placed-part counts, distinct non-fastener-design counts, functional-subassembly counts and model bounds; and measured interference/clearance reports at defined motion endpoints. The targets of 60–100 placed components, at least 25 distinct non-fastener designs and at least 8 functional subassemblies remain unchecked targets, not reasons to add BOM items."
  ],
  "recommendations": [
    "Ask the later builder to define endpoint and moving-part assumptions before checking Y carriage/gantry, X carriage/screw and Z guide/screw sweeps. Review the X rail-to-carriage face, screw-to-carriage drive interface, focus mounting and camera-to-focus connection separately from any measured clearance result.",
    "Request sections and access views for deck holes and standoffs, fixture reach, optics-to-backplate spacing, controller lid and eight vent features, rear/side panels, twelve-link carrier routing from its supplied start, and cable/service access. Record analytic questions now; reserve pass/fail and distances for later geometry evidence.",
    "Use synthetic record-transition cases only: matching manifest and fixture references may permit staff confirmation; a changed fixture, changed manifest, stale browser view or missing image reference should block confirmation pending reconciliation; incomplete handoff should remain unacknowledged. These are expected record outcomes, not executed tests. Neither confirmation, export nor acknowledgement verifies physical setup or permits energized operation."

  "concerns": [
    "Potential explicit geometry conflict: if P13's 32 × 32 body is centred on the supplied optics axis X270/Y110, its Y extent is 94–126 and Z extent is 190–230. The unrelieved P10 backplate spans Y124–132 and Z164–344, so their nominal solid envelopes overlap. Camera-body placement and the intended mounting relief are unresolved; do not silently move either.",
    "Potential explicit geometry conflict: if P15's ring is centred on that same axis, its outside diameter reaches Y134 and its Z span is 158–168. The backplate begins at Y124 and Z164, so portions of a nominal unrelieved ring and plate can intersect. Ring attachment, centring and relief require a defined interface and later section check.",
    "Y carriage count and locations, X and Z travel endpoints, gantry tower footprints, side-panel placement, controller mounting, carrier path/end connection, cable bend and service clearances, and foot Z placement are absent. The supplied dimensions do not resolve them. The controller nominally spans X360–515, Y286–386, Z12–70; the rear panel starts at Y400, but that separation alone establishes no service access.",
    "The record-to-image crosswalk has no produced image source yet: IMG-ASM, IMG-EXP and IMG-SEC are pending builder references, not existing files. FX-DECK-GRID-r1 is a proposed setup reference, not a supplied workholding part. Missing references must remain flagged rather than treated as verified."
