Subfield manufacturing engineering handoff

Current disposition: development. The complete system is not ready for manufacture.

The R10 lock clearance revision increases the foot hole to 5.0 mm. Its worst studied radial clearance is 0.263 mm against the unchanged 0.10 mm target; nominal retainer contact remains. Focused geometry and capture checks pass. Full regression is running. Forming inputs remain unqualified, and head seating, contact pressure, retainer behavior, material and physical qualification remain open.

The R9 formed carrier replaces the prior mixed-thickness return with a nominal uniform 4 mm section and an explicit 4 mm inside bend radius. The captive screw neck is lengthened to preserve engagement and release. Geometry, STEP, thickness/radius, motion and focused tests pass; full R9 regression is running. Material, tooling, bend allowance, springback and forming capability remain unresolved. This closes a nominal geometry inconsistency, not the manufacturing-release gate. Earlier R8 findings remain historical below.

The carrier fabrication review finds mixed 4 mm/3 mm thickness and an undefined sharp return corner. A uniform-sheet flat pattern cannot represent the current solid. Select and model a fabrication route and any required joint before manufacturing.

The R8 clearance revision increases the rear-mount openings and stud neck lengths to address the R7 fit-budget shortfall. The same proposed tolerance/coating budget now leaves 0.285 mm radial and 0.45 mm axial clearance. Nominal geometry, motion/capture and two focused tests pass. Full R8 regression remains running; R7 test results do not cover R8. These are unqualified prototype assumptions; production capability and physical verification remain open. The three R8 review sheets now show carrier/stud details, lock sections and revised sliding clearances; complete production drawings remain unfinished. The visual gallery still shows R7.

The latest Core R7 mechanical assembly has 81 separate parts, internal tray/faceplate attachment, a nominal power-compartment barrier and a captive rear mounting arrangement. Source-copy reproduction matches all 81 STEP bodies. Its 1,132 nominal fit/export checks and 1,188 release checks pass; full R7 repository regression passed: 332 tests in 1520.22 seconds. Earlier full test counts below belong to their stated snapshots.

The new prototype fit budget identifies a required next revision: coating and proposed dimensional variation reduce the three examined sliding gaps below their proposed targets. This is a local worst-case calculation with unqualified process assumptions, not a released tolerance specification. Current R7 geometry is unchanged. Actual electronics, wiring, threads, materials, structural loads, physical fit and environmental qualification remain open.

The R4 product gallery includes 14 groups and 22 CAD views, with updated Core closed, service-open and rear-mount views. The tank remains R2 and the other twelve standalone groups retain their earlier geometry.

The current dual-opening roof review adds an elastic demand model tied to the R2 CAD: both opening frames, 12 explicit T-joint offsets, 18 separate bearings and three continuous support rails. The package includes sixteen cases, signed connection/support/member loads, source, figures and verification. All 74 focused tests, 66 analysis checks and 234 independent output checks passed. This adds no geometry, strength rating, qualified laminate/joint, or manufacturing release; component coverage remains unchanged.

The current product gallery contains actual CAD renders for fourteen product groups. The revised tank has 32 rectangular recessed panels, a continuous orange band, refitted partition edges and 2,753 separate solids. The thirteen standalone accessory concepts now have graphite/orange surface presentations. All 232 CAD tests and 54 whole-tank fit/export checks passed; manufacturing qualification remains open. The earlier four AI appearance boards remain illustrative references. Historical geometry and evidence below are preserved as separate revisions.

The preserved closed-partition baseline vessel with closed process partitions has 2308 solids and the 500 mm access configuration. The partition package contains individual parts, editable source, liquid-reference solids, revised pilot-fit evidence and drawings. Hydraulic connections and actual process equipment remain incomplete. The earlier 4572 mm access model is retained as a separate snapshot and does not yet include these partitions.

Preserved partition-baseline evidence

The partitions add 73.38 kg at assumed densities. The incomplete tank is 441.90 kg (974.2 lb); the incomplete 500 mm installation is 491.84 kg. The approximately 500 lb target is not met and a complete cost is not verified.

Normal liquid inventory across the three proposed levels totals 2018.05 gallons before remaining equipment and solids displacement. Geometric headroom totals 281.71 gallons; its availability to incoming flow is unresolved, so it is not a usable-reserve claim. The partition generator passed 101 checks; revised actual pilot positions passed 5 fit/extraction/STEP checks; the CAD suite passed 103 tests. Earlier screen/carrier transforms intersect the partitions and are superseded for this layout.

Complete scope still outstanding

The Notion coverage map spans twelve component groups. Beyond the geometry above, complete the required baffles/flow paths, shell/riser/roof seals, lift and level interfaces, hydraulic docks, distributor/collector/split/sample components, actual Hub and alarm arrangements, sensor mounts, connector/cable families, selected field integration and technician tooling. Optional research and non-geometric software scopes need explicit dispositions. The map is not yet a completed row-by-row manufacturing manifest.

Continue preliminary engineering under the owner's authorization, with later approvals. Close interfaces and whole-assembly loads while selecting actual materials/processes and supplier envelopes. Complete process-specific drawings, tolerances, laminate/adhesive and hardware definitions, tooling, assembly instructions and inspection criteria. Correlate the analysis with material, joint and system tests, then obtain controlled release approval. The original R0.1 source and its open gates remain source records; newer geometry choices are stored in their own parameter sets.

The latest original Subfield design review is ../product-design-r1/index.html and ../product-design-r1/Subfield-Product-Design-R1.pdf. Ten new concept assemblies, 101 parts, 15 CAD scenes and 150/48 scope/product ledgers are packaged in ../subfield-product-design-r1.zip. 108 CAD tests and the assembled interference audit pass. New electronics housings, filter housing, connectors, sensor carrier, pump dock and case remain unintegrated concepts with supplier internals absent. The process-partition tank master above remains authoritative and unchanged. These renders do not close the remaining manufacturing work.

../media-hydraulics-r1/Subfield-Media-Hydraulics-R1.pdf reviews the new nine-outlet distributor, sloped collector and revised service carrier. The 37-part assembly and 2352-solid tank fit pass geometry/transport checks; 115 CAD tests pass. Two dimensioned B-rep sheets and six branded renders accompany the source and STEP files. The first lift test exposed a mounting-ear/rung collision, corrected by shortening the rear overhang and inlet. Three existing partition surfaces retain a documented numerical volume-integration disagreement; empty bidirectional B-rep subtraction verifies their geometry equivalence instead. This is kernel-level evidence, not a manufacturing tolerance claim.

This increment does not replace the current permanent tank master. Media, process duty, supply and drain connections, qualified split, captive retention, tank mounts, materials, manufacturing tolerances and complete no-entry service remain unresolved. Some illustrative flow/fouling cases exceed the distributor rim and must not be treated as allowed operating points. The latest 150-scope coverage ledger is ../media-hydraulics-r1/component-coverage.json.

Gravity receiver R1 / controlled alternative

The new 36-part receiver has separate recycle/final passages, a removable socket and two compressed seal studies. Its tank candidate cuts five actual partition layers and adds five permanent interface parts. The media stage is raised to Z1100. Receiver removal uses -55 mm X / -10 mm Y after media and mount hardware removal. Final geometry, full CAD tests, source hashes and the six renders are in gravity-receiver-r1; subfield-gravity-receiver-r1.zip is the verified package.

The closed-partition master remains the current permanent assembly. The altered tank is a separate candidate: no calibrated split, service isolation, revised capacity or penetration strength qualification is claimed. The open sleeve can pass EQ above Z980 into final during service. Retained-liquid cleanout, qualified materials/seals, real media/plumbing, grade operation, long guides and tank attachment remain required.

Receiver isolation R1 / controlled alternative

The new 49-part candidate adds a retrievable bayonet cartridge, guided spring-return poppet, compressed seals and nominal hardware. Closure occurs after 12 mm receiver withdrawal in ideal geometry, 1.5 mm before first socket-ring exposure. Full receiver release is -65 mm X / -10 mm Y, with a shortened open return spout. The separately isolated cartridge turns 45 degrees and withdraws 200 mm before lifting. Geometry, STEP transport, full CAD tests, six renders and the preserved initial failed fit are in receiver-isolation-r1; the verified package is subfield-receiver-isolation-r1.zip.

The closed-partition tank remains the current permanent master. Nominal seat contact is not leakage or isolation qualification. Cartridge removal opens the sleeve and requires independent chamber isolation; grade operation, captured drains, long guides, tolerance and spring/seal/material/retention qualification remain unresolved. Abnormal EQ/backwater bypass and complete process integration remain open. Earlier receiver R1 evidence is preserved as an earlier alternative. The coverage ledger remains 48 partial, 66 not modeled, 31 deferred and 5 non-geometric scopes.

Coarse screen R1 / controlled alternative

The new F1 candidate adds a 2,352-hole insert, closed-base support, potted ends, gasketed head, two capture-ring studies, three-pin bayonet cup and captive anti-rotation plunger. The cup captures before the nominal cartridge withdrawal. Actual source, separate STEP parts and states, shallow-tank fit, eight renders, drawings and complete CAD tests are in coarse-screen-r1; the verified package is subfield-coarse-screen-r1.zip.

The 32 mm top outlet remains unconnected. Grade lift/turn actuation, guides, primary level/transfer and independent isolation, cap retention, controlled waste handling, material/process/tolerances and physical qualification remain open. The closed tank master and prior receiver alternative remain unchanged. Area and filled-interior mass are analytical hypotheses, not flow ratings or lift limits. The first failed potting/retainer and bolt/capture-ring checks are preserved. The coverage ledger still records 48 partial, 66 not modeled, 31 deferred and 5 non-geometric scopes.

Grade service R1 / controlled alternative

The F1 alternative now includes a tubular capture mast, long guided lock plunger, independent retainer drive, fixed guide, side-loading long service cap and captive keeper. The 42-part model and 2434-body shallow tank fit pass 147 CAD tests; six actual-CAD renders, nominal drawings and source-linked checks are in screen-grade-r1. The verified archive is subfield-grade-service-r1.zip.

Only the 500 mm cover case is developed. Connected screened transfer and isolation, tank support, a qualified lifting aid, wet loads, materials, joints, free seals and manufacturing qualification remain open. The full 150-scope coverage ledger retains 48 partial, 66 not modeled, 31 deferred and 5 non-geometric entries. Previous master and candidate packages remain unchanged.

Screen transfer R1 development evidence

The latest separate candidate is Screen transfer R1, with 93 raw parts, 2485 solids in the complete tank fit, 154 passing CAD tests and six actual-CAD Subfield renders. Download the development package.

The candidate adds a vented F1 bridge, spring-return receiver with bolted assembly access, opening cap guide, grooved hinge-pin retention, open-front mast guide, external support lugs, P1 sleeve and four core-closeout anchor studies. Nominal closure precedes the two seal-exposure events by 2.4 and 4.4 mm. These geometric margins do not establish physical isolation. Full shallow-tank and independent-lane fit, sampled assembly/service motions and STEP transport are recorded in the package.

The complete render library now contains 57 renders across 51 scenes and 7 review PDFs. The coverage ledger remains explicit: 48 partial concepts, 66 not modeled, 31 deferred and 5 non-geometric. Materials, laminate/joint/anchor qualification, flow and spring performance, tolerances/seals, bridge retention, safe drainage/flush, no-entry servicing, wet lifting and deep-cover variants remain open. The closed permanent tank master remains unchanged.

Side-level R1 development evidence

SC-012 side-level cartridges now has four 34-part units, eight survey heads and a 2,621-body complete tank candidate. The verified development package contains editable source, raw/assembly STEP, four renders and a twelve-page review with seven B-rep drawing sheets. All 161 CAD tests and 15 whole-tank checks pass.

The supplier EL80 web geometry is preserved intact through a controlled STEP entity-graph path because ordinary OCCT re-export corrupts one cosmetic marking face. Exact source geometry, four placements and individual-body transport remain verified; no supplier geometry was suppressed. The drawing/web mounting-bore discrepancy remains explicit.

These are exposed-side installation/service units with external bonded supports, located replaceable carriers and captive protective covers. Physical calibration, reference repeatability, local shell/bond loads, material/process/tolerances, soil/thermal/chemical exposure and installation acceptance remain unresolved. Four local bubbles do not prove absence of tank distortion or settlement. The closed permanent tank master remains unchanged.

The render library now contains 61 renders across 55 scenes and 8 review PDFs. SC-012 moves from not modeled to partial: the ledger is 49 partial, 65 not modeled, 31 deferred and 5 non-geometric. The full manufacturing objective remains incomplete.

Tank pipe mounts R1 development evidence

SC-009 pipe mounts adds two six-part original reinforcement assemblies and two actual shell cuts. The verified development package includes a separate 2,633-body tank candidate, twelve raw parts, two unit assemblies, six renders and a ten-page review containing six B-rep drawing sheets. All 167 CAD tests, 30 unit checks and 25 whole-tank fit/export checks pass.

The initial inlet position clashed with a roof rib. A 15 mm downward revision preserves the full ring and leaves at least 10 mm nominal clearance; the candidate pipe invert becomes 1585 mm. The original failed fit and resolution are preserved. Inlet hydraulics and installation tolerances remain unresolved.

The proposed Hayward fitting interfaces use controlled published dimensions. Original fitting CAD requires business-contact registration, for which user details remain pending. No form was submitted and no fitting, nut, gasket or pipe body was substituted in the model. Actual hardware, internal tee/baffle, pipe routing, independent supports and movement isolation remain open, along with material/process/tolerance, local shell/laminate/joint loads and physical leakage qualification. Both prior tank inputs remain unchanged.

The product render library now contains 67 renders, 59 scenes and 9 review PDFs under the original Subfield identity. SC-009 moves to partial: 50 partial concepts, 64 not modeled, 31 deferred and 5 non-geometric. Complete manufacturing design remains in progress.

Body handling R1 development evidence

SC-013 body handling adds two original underside saddles aligned with permanent base crossmembers 2 and 5. The verified package includes sixteen raw part STEP files, the local saddle assembly, a separate 2,665-body tank candidate, four CAD renders, native Blender/GLB and a six-page review with three B-rep drawing sheets. All 173 CAD tests, 34 unit checks and 31 whole-tank fit/export checks pass.

Thirty-two added solids clear the actual tank and existing side-level extraction corridors. Six lower pads match the existing inner shoe footprints. Outward rigging-space references clear the roof; four inward center-hook reference legs intersect the tank. Those orange volumes are explicitly references and are excluded from the product STEP. No sling, protector, hook, spreader, WLL or lifting authorization is supplied. Roof-only handling remains separate and undeveloped.

Assumed additional mass is 20.20 kg. The earlier 500 lb tank target remains unmet. Lower guides project 24.5 mm beneath the tank, changing bedding support and sling-removal requirements. Coupled saddle/pad/bond/skin/shoe/frame strength, stiffness, slip, dynamic loading, complete mass/CG, actual rigging, manufacturing process/tolerances and physical qualification remain open. Nominal contacts do not establish a qualified load path. The preceding tank candidate and permanent closed master remain unchanged.

The product render library now contains 71 renders, 63 scenes and 10 review PDFs. Coverage is 51 partial concepts, 63 not modeled, 31 deferred and 5 non-geometric scopes. Complete manufacturing design remains in progress.

Primary access R2 development evidence

The primary access revision replaces the old 350 mm aperture with a 520 mm nominal throat at X -775.5, Y +550 mm. The 500 mm cover candidate includes a recessed integral handle, twelve captive closure stations and a separate guard. The package contains a 2,753-body full tank, rebuilt roof, access STEP, nine raw part STEP files, native Blender/GLB, four actual CAD renders and a six-page review with three B-rep drawing sheets.

The permanent roof now has two beam-02 stubs, two headers, six T-wrap/bond joints, an annular curb and regenerated deck ribs/bearings/bonds. Intersecting positive-Y bearing seats follow the new wraps. Prior roof reaction studies do not establish the capacity of this revision. The preceding tank and permanent closed master are unchanged; existing saddles, process equipment and original supplier levels remain in the revised candidate.

All 178 CAD tests, 8 access checks, 22 whole-tank fit/export checks and 18 reimported T-joint contact checks passed. Two small adhesive overlaps at notched ends were corrected by clipping adhesive outside mating stock without relaxing the intersection tolerance. STEP transport preserves every body and original supplier face geometry.

Santa Cruz County 7.38.140(B) supplies the 20-inch minimum-dimension manhole screen and durable-handle requirement. This candidate addresses nominal throat geometry only. The integrated enhanced-treatment approval path, actual compartment access, capacities, effluent-pump chamber provisions and installed tolerance remain unresolved. The lower crossmember rejects a full-depth cylindrical reference; pumpout reach, inlet cleaning and no-entry service have not been qualified.

Complete coupled roof/joint analysis, laminate and process, production tolerances, cover/guard/handle ratings, physical tests and manufacturing release remain open. The earlier 4572 mm riser study is not revised by this package. Coverage remains 51 partial concepts, 63 not modeled, 31 deferred and 5 non-geometric. The render library now contains 75 renders, 67 scenes and 11 review PDFs.

Recessed shell and graphite product family R2

The current product gallery presents actual CAD renders for the revised tank and thirteen standalone product concepts. Graphite surfaces, restrained orange accents and exact Subfield artwork follow the owner's supplied reference. The earlier AI boards remain appearance studies; their complete geometry has not been adopted.

The tank review contains 32 blended rectangular wall panels, a flat identity band, restored controlled port bores and fourteen refitted partition perimeter bodies. It retains the current two-opening roof, process equipment, handling saddles and original supplier level geometry in a 2,753-solid assembly. The archive includes the full STEP, normal-offset panel references, three dimensioned drawing sheets, three CAD renders with packed Blender files, executable source, checks and a geometric level-volume inventory. All 232 CAD tests and 54 whole-tank fit/export checks passed.

The standalone family contains nineteen renders and packed native scenes for thirteen existing product-design-r1 concepts, with corrected surface finishes and readable functional markings. Its archive preserves original source-scene hashes. It does not replace later detailed mechanisms or qualify electrical, hydraulic or supplier functions.

The engineering review lists the changed shell's unresolved laminate, process, tooling, tolerance, bond and structural work. Historical spherical-panel and single-opening roof calculations do not qualify the revised geometry. The three-cell inventory separates modeled-material displacement from an assumed sealed structural-stock case; it is not usable capacity. No burial, traffic, lifting, lifetime, cost or production-weight rating is issued.

The coverage ledger remains 51 partial concepts, 63 not modeled, 31 deferred and 5 non-geometric. All release-ready flags remain false. Existing historical packages and the permanent closed master remain recorded separately.

The Core review develops the current 360 x 600 x 150 mm exterior enclosure with a defined seal groove, captive commercial screw envelopes, custom pinned hinges and a nominal 110-degree opening stop. It contains 30 separate parts, four assembly poses, five drawing sheets derived from CAD and two graphite Subfield renders with packed native scenes. Twenty-eight focused mechanism tests pass. The complete CAD suite passed 318 tests. The updated family gallery includes the new Core views.

The actual divider cannot withdraw straight through the new frame. A 20-degree in-plane rotation followed by withdrawal clears the housing in the recorded geometric check. Both faceplates and the tray clear their straight extraction envelopes; attachment, cable and human-access definition remains incomplete. This is packaging evidence, not a qualified service procedure.

The coverage ledger retains 51 partial, 63 not modeled, 31 deferred and 5 non-geometric scopes. All release flags remain false. Production material/process/tolerance, cover stiffness and seal force, hardware formation/thread capacity, actual electrical packaging/barriers/thermal design, internal/rear attachments and physical qualification remain open. The complete system is not ready for manufacture.
