grabowski 15d28d2e0b Plant assistant: one agent management and operators can ask 
New docs/plant-assistant.md (decision, Alexander, 26 Oct 2026): an
assistant for the whole plant, asked in Thai or English at kiosks, desks
and phones, answering from the knowledge base (SOPs as ERPNext Quality
Procedures, vendor manuals on the Assets, recipes and limits, this
repository, lessons learned) and from ERPNext and the machine-data store,
with sources on every answer. Roles and questions, what it does
(explain, trace, summarise, alert context, plan vs actual, drafts) and
never does (machines, submitting, safety improvisation, seeing more than
the asker, rating operators, needing the internet). Built on Typhoon 2.5
(open weights, Apache-2.0, CPU trial first), Typhoon ASR for optional
voice, pgvector retrieval, MCP tools in cnx-factory through the one
integration layer and the PostgreSQL replica; vinyl-ai GPU server only if
needed (~250k to 300k THB, RTX 5090 Thai retail Oct 2026). Test set per
role, phasing, cost, risks, open decisions.

Mirrors: digital-factory systems and machines tables, rough cost note;
catalogue advisor becomes a role of the assistant; worker-safety
training; roadmap item 18; README bullet and layout.

grabowski d36a6fdd02 Own catalogue: sales map, demand model and market advisor (plan) 
New docs/catalogue-intelligence.md for Alexander's idea of a catalogue
the plant presses for itself. Why (idle Classic hours ~60k to 160k
records a year at 60 % specials on the doc basis; two-week represses
from the metal archive; Thai catalogue sells in Japan, EM Records,
ZudRangMa), scope (Poy Records as seed; customers' data and press dates
protected), data sources with access terms (Bandcamp ship-to fields,
distributor sell-through clauses, opt-in record passport registrations,
Spotify for Artists, Discogs CC0 dumps; Discogs API marketplace and
want data restricted), ERPNext touchpoints (Licence, Channel Sales
Report, Catalogue Recommendation, geocoded addresses, CRM), PDPA rules
for the map, dashboard views on an open-source map stack, a staged
demand model with a stocking rule for run size, a propose-only advisor
on an open-weights model, phasing, cost estimates, risks and open
decisions.

Backlinks: README (planning documents, layout), roadmap item 28,
digital-factory tool rule, artist-platform repress pre-orders,
production-timeline repress, revenue-model ResurRec Japan.

grabowski 793ea02c22 ResurRec Japan: demand in Japan and whether it serves all of Asia 
Revenue model, ResurRec Japan section: RIAJ 2025 vinyl production
(3.38M records, 8.4bn yen, fifth year of growth), short domestic supply
(6 to 12 month lead times at Toyo Kasei and Sony per P-Vine, orders
placed abroad via brokers), the photographed presses at about a fifth of
Japan's volume on one shift. No published Asia-wide intent; the rest of
Asia has local plants, so Japan-from-Japan and SEA-from-Bangkok is our
reading. Consequence for CNX's ~0.74M regional demand (roadmap item 1).
 2026-10-26 16:58:23 +07:00
grabowski 7fca116edb ResurRec Japan vs CNX launch plant: capacity table 
Revenue model, ResurRec Japan section: 3 AD12s as photographed against
one Duplex system + one Classic on the scale.md basis (60 to 70 %
effectiveness, 300 days): ~1.6x per hour on black and solid colours,
one Japan shift matches CNX's two; specials comparison waits on the
AD12 splatter-mode rate; steam load about the same.
 2026-10-26 16:38:27 +07:00
grabowski 39342f3a7e ResurRec Japan: press capacity of the three AD12s in the photo 
Revenue model, ResurRec Japan section: ~2,000 to 2,500 records a day,
~0.6 to 0.76M a year on one shift, ~1.2 to 1.5M on two (Pheenix 24 to
26 s cycle, the table's 60 to 70 % effectiveness, 300 days), about CNX's
launch plant at 60 % specials. Black and solid colours only; splatter
runs semi-automatic on the AD12 with no published cycle time.
 2026-10-26 16:35:43 +07:00
grabowski d968ee5b08 ResurRec Japan: photos of the new plant, presses read as new Pheenix AD12s 
Four photos of ResurRec's new Japan plant (October 2026) filed in
docs/finance/resurrec-japan/. Revenue model gets a "ResurRec Japan"
section: what the photos show (visitor window, automatic presses in
aluminium cabinets that Alexander identifies as a new red AD12
generation, ceiling services, air-conditioned room, no plating in view),
what it changes (scaling abroad, Japan export wedge narrows, Classic vs
AD12 evidence, collaboration depends on their metal path) and open
questions. Also notes a directory listing naming an M-Tech Allegro II in
Bangkok against the tour's Newbilt Classic.

Mirrors: Pheenix sections in vendor-landscape, exhibitor questions and
supplier map; pressing-line AD12 paragraph; roadmap item 5; visitor
corridor in crane-workshop-tours; README status and layout.

grabowski f6829417a0 Test site: DNS moves to the fleet nameservers, no Cloudflare proxy
Deploy test site / deploy (push) Successful in 1m4s
Details 
cnxvinyl.lol's zone now lives in cnx-network-clan (ns1/ns2.cnx.network),
pointing straight at s1; mail is on mx1. Live once the nameservers at
Porkbun are switched.

- site/Caddyfile mirrors what s1 runs (checked 2026-10-23): no
  cloudflare_only or security_headers imports; Caddy gets its own certs.
- deploy-site.yml: drop the Cloudflare cache purge step and its secrets.
- site/README.md and digital-factory.md: DNS and certificate notes.

grabowski 1f532d0c85 All-equity funding: shareholders fund the whole plant
Deploy test site / deploy (push) Successful in 1m0s
Details 
User, 20 Oct 2026: the plan is that the shareholders fund the whole
plant and get shares for that (no bank loan).

- total-investment.md "Two plans": Funding paragraph: Plan B's ~217M
  THB paid in as share capital; the lead investor's 60 % at least ~130M,
  the 40 % at most ~87M (~121M / ~81M before the reserve; Plan A ~109M /
  ~73M); capital registered in full and called in instalments against
  the tranches; BOI's 3:1 met with no debt; nothing pledged.
- boi.md, README Project Status and the share-price bullet follow.
- Business plan A and B: the ask, the decisions, section 12.2 (funding
  bullet replaces the 3:1 equity floor), section 14 and the BOI
  requirements paragraph; "not in this plan" now names bank debt; both
  rebuilt (63 pages, checked).
- share-price.md re-based: 2,170,000 shares of 100 THB, the 40 % ~86.8M
  THB; illustrative calls 25/40/20/15 % against the tranches; premium
  rows on 217M; value per share once running with no debt (adverse 11 to
  42 THB, central 80 to 314, favourable 176 to 688 per 100 THB paid);
  VC method and CAPM recomputed; the calculator's ~22 % IRR is now the
  shareholders' pre-tax return (~18 % after tax, rough); missed-call
  rules (CCC 1120 to 1125); the levered case kept as "if a loan were
  added later".
- Deck: slide 12 (all equity, 60/40 bar ~130M / ~87M, none pledged,
  share capital called in instalments), slide 13 (re-based table, chart,
  premium cards, VC line), slide 17 (co-investor card, calls) and notes
  ("lenders" -> "investors"); both PDFs rebuilt; deck verify clean.

grabowski 1829dd2aec Share price for the 40 %: market-based ranges, deck slide 13
Deploy test site / deploy (push) Successful in 1m4s
Details 
User, 20 Oct 2026: add a page about possible share prices, do some
calculation on normal market data.

- docs/finance/share-price.md (new): market data with sources and
  dates (Damodaran January 2026 EV/EBITDA, P/E and betas for emerging
  markets and global; Thailand ERP 6.18 % (July 2026); ThaiBMA 10-year
  2.30 % (19 Oct 2026); illiquidity discount 20 to 35 %; venture target
  returns by stage; SET peers SCGP, TPAC, SITHAI, GRAMMY; Thai Civil and
  Commercial Code on par value and premiums).
- Results, all estimates: A founding round at par, pari passu: 542,500
  shares of 100 THB at Plan B's 54.25M equity floor, the 40 % ~21.7M
  THB; B a premium only for documented pre-round costs (102 to 137 THB);
  C value per share once running at ~163M THB debt: adverse ~0, central
  126 to 1,016 THB, favourable 508 to 2,512 THB; D a financial investor
  today 18 to 236 THB (central); E calculator cross-check. Recommendation:
  par for the founding round; pre-emption and information rights for the
  40 %.
- Deck: new slide 13 "Share price: what the 40 % could cost" in both
  themes, with notes; the ask slide points to it; 17 slides, both PDFs
  rebuilt; site slide notes trimmed.
- README bullet, layout line and Project Status link; total-investment
  shareholding paragraph links the page.

grabowski 967e6b1c76 Payap still an option: rezoning route; order example opaque
Deploy test site / deploy (push) Successful in 2m40s
Details 
User, 20 Oct 2026: Payap University claims they can rezone the land;
update the deck to show it is still an option. And: do not use a
transparent vinyl as the example in the order tool screenshot.

- land-listings/payap/rezoning-2026-10-20.md (new): what a rezoning is
  under the Town Planning Act B.E. 2562 (section 35 amendment started by
  DPT or the local official, Town Planning Commission, 30-day posting
  with objections, Ministry of Interior notification via Cabinet and the
  Royal Gazette; a landowner can ask, not rezone), the DPT's own work
  plan (~70 weeks without objections, ~82 with: ~16 to 19 months), the
  schedule effect (roughly a year on first production unless the request
  starts now; estimate) and what to ask Payap. DPT procedure PDF filed.
- site-candidates.md: Payap "still an option" in the table, rezoning
  paragraph with an Open action, check 1 and the re-siting rule; zoning
  record, payap-partnership.md and README point to it.
- Business plan 6.1, risk table and critical path: Payap's rezoning
  claim and its ~16 to 19 months; A and B rebuilt (63 pages, checked).
- Deck: site slide names Payap as an option once rezoned, notes and
  source line; risk row updated.
- order.html: the "Splatter 12"" preset now has a white base instead of
  clear; deck platform screenshots re-shot in both themes (numbers
  unchanged: 100 fans, break-even 46, ~480 THB kept). Order checks 96/96,
  fan parity 206/206; deck verify clean in both themes, PDFs rebuilt.
 2026-10-20 14:58:40 +07:00
grabowski 744a56d22b Order tool: fan funding; deck: light and dark, 60/40 shareholding
Deploy test site / deploy (push) Successful in 1m2s
Details 
User, 20 Oct 2026: can the deck also be made in a light and dark mode;
the new order tool should also offer fan funding, so the platform
screenshots match and use the same calculator; the main investor holds
at least 60 %, so 40 % is for sale.

Order tool (docs/order.html, /demos/order/):
- New step 15 "How to pay": pay the plant directly (deposit) or let
  fans fund it; step 16 becomes "Review & launch" with the campaign
  simulation and its three outcomes.
- Campaign maths ported from make-a-record (fan price, length, cap, own
  copies, VAT; fans needed = max(100, break-even); keep at the goal and
  with more fans; price hint); R gains fee (3.5 %), VAT and campaign
  length with sources; no price changed.
- Quote card shows fan price, fans needed and the artist's keep on the
  fan route; route and campaign in the #q= hash; deep links
  #s=<step>&p=<preset>&route=fans.
- Parity with make-a-record: 206/206 checks over 40 configurations;
  default quotes unchanged (37,836 / 217 / 102,936 THB; partner
  mastering 43,676).

Investor deck (docs/pitch/):
- Light and dark theme like the other site pages (cnx-theme, T key and
  button), presenter and overview follow; charts from CSS variables;
  text pairs at WCAG AA in both themes; tool screenshots in both themes.
- Two PDFs: dark and light (print-friendly), each ~1.5 MB.
- Platform slide: both pictures from the order tool (Splatter 12" order
  step and its fan-funding view: 100 fans at 1,200 THB, break-even 46,
  ~480 THB a copy kept).
- BOI and financing slide: shareholding bar, lead investor at least 60 %,
  at most 40 % for co-investors (~32M / ~22M THB at the ~54M equity
  floor, arithmetic only); the ask offers up to 40 %.

Docs: artist-platform.md (fan funding in the order tool), README and
landing page entries.

grabowski c8307f9d5e Shareholding: main investor holds at least 60 %, 40 % for sale 
User, 20 Oct 2026: the main investor W wants to hold at least 60 % of
the company (the BOI-promoted company), so only 40 % is for sale.

- total-investment.md "Two plans": the 60/40 rule; Ploy Printing's
  stake, founders' shares and any further co-investor come out of the
  40 %; at Plan B's ~54M THB equity floor (3:1) and one share price
  that is at least ~32M / at most ~22M THB (arithmetic only; share
  price, valuation and in-kind shares not agreed).
- README Project Status and boi.md (foreign-ownership privilege) point
  to it.
- Business plan: section 12.2 states the split (A: ~28M / ~18M, B:
  ~32M / ~22M at the equity floor, arithmetic), the co-investment bullet
  and the decisions list name the 40 %; A and B rebuilt (63 pages each,
  TOC and em-dash check clean).

grabowski 81de64c8a1 Investor deck rebuilt around Plan B (16 slides)
Deploy test site / deploy (push) Successful in 59s
Details 
User, 19 Oct 2026: build the deck again but focus on Plan B, the main
investor wants to go with that.

- Proposes Plan B, ~217M THB at the midpoint (~6.56M USD), labelled
  ~215M; Plan A (~182M) only as the comparison. Every running footer,
  source line and speaker note now presents Plan B.
- New slide 9 "Why Plan B": ownership and control, not a higher
  modelled return (owned roof PV and battery instead of a PPA, full
  metrology from the first release, corridor and tours from day one,
  cassette and CD-R, bought crane, Thai utilities; ~34.5M THB together);
  Plan A has the better modelled return, owning the array earns no BOI
  tax benefit.
- Investment by block for Plan B with low-high ranges, the "what Plan B
  buys" table, no contingency (~30M at 15 %); operating picture, cash
  curve (payback ~4.2, IRR ~22 %, NPV ~4.7M USD) and BOI slide (equity
  at least ~54M THB at 3:1, owned PV and battery as collateral) for B;
  B-specific risks; the ask with the Plan B tranches only.
- Plan B renders replace the Plan A ones; PDF regenerated, 16 pages,
  1.5 MB.
- README and landing page entries say 16 slides and Plan B.
- Checks: every slide at 1920/1440/1280/390 px without overflow,
  navigation and presenter sync, PDF pages and text, no em dashes.
 2026-10-20 13:45:30 +07:00
grabowski 995bb4ba60 Plan B chosen; stale mirrors fixed; business plan rebuilt 
User, 19 Oct 2026: the main investor wants to go with Plan B; fix the
stale docs the deck build found.

- total-investment.md "Two plans" and README: the main investor wants
  Plan B (~217M THB, labelled ~215M); Plan A stays as the comparison.
- boi.md: duty without BOI on the launch plant's ~2.3M USD of imported
  machinery (~0.11M duty, ~0.17M import VAT), as total-investment states;
  the calculator's ~2.5M includes the water treatment; the old ~2.75M
  was the superseded start fleet.
- roadmap.md item 2: the BOI application stacks automation, R&D and the
  battery if it qualifies; solar lost promotion on 1 July 2025.
- project-timeline.md: October re-read note (launch plant with
  galvanics commissioned first, long lease of raw land, Plan B price;
  calendar not redrawn); galvanics rows no longer "Phase 5".
- revenue-model.md: blended price at 60 % specials ~124 to 174 THB
  (3.76 to 5.27 USD), the Thai gap "three to six times".
- site-candidates.md, scale.md: utility yard with air-cooled chillers,
  no cooling tower; electroplating permission needed from the start.
- Business plan: working capital 4.5M to 9.6M THB (as total-investment);
  A and B docx and PDF rebuilt (63 pages each, TOC checked).
 2026-10-20 13:26:28 +07:00
grabowski 40c049ae15 Investor deck: 15 web slides with presenter view, plus PDF
Deploy test site / deploy (push) Successful in 55s
Details 
User, 19 Oct 2026: build a high-end investor pitch deck; the whole
plant, web slides on the test site with presenter mode plus a PDF,
12 to 15 slides, both plans, for a BOI / bank / institutional reader.

- docs/pitch/index.html (site /pitch/): title, opportunity, the chain
  under one roof, how a record is made (9 stages, 3 gates, traceability,
  ERPNext), platform, site and building, sustainability and region,
  investment A vs B by block with the six levers (no contingency in
  either price), operating picture with the adverse case, ten-year cash
  and returns (calculator presets), BOI promotion and the 3:1
  debt-to-equity condition (financing structure to be agreed), schedule,
  risks, team and vendors, the ask (phase 0 then tranches).
- Every figure carries a source line (business plans draft 0.3 and the
  owning docs); speaker notes per slide; P opens a synced presenter
  window, O the overview, F fullscreen, #n deep links.
- img/: six WebP pictures (calculator renders, order tool, fan funding,
  record passport); CNX-Vinyl-Investor-Deck.pdf, 15 pages 16:9, images
  re-encoded to 1.5 MB.
- site/build.sh copies docs/pitch/ to /pitch/ (new DIRS list); the
  deploy also triggers on docs/pitch/**; landing page and README entries.
- Checks: 15 slides at 1920/1440/1280/390 px without overflow, navigation,
  presenter sync both ways, PDF pages and text, no em dashes.

grabowski 7d6a47e6d0 Order tool v2: step-by-step configurator after mobineko.com/order
Deploy test site / deploy (push) Successful in 51s
Details 
User, 19 Oct 2026: build a new version of the order tool like
mobineko.com/order; it should also offer selectable mastering like
brandenburgmastering.com at 60 USD a track.

- New docs/order.html (site /demos/order/): 15-step rail, step panel,
  large live SVG record (colour per disc, translucent, split, splatter,
  marble, colour-in-colour; label, dead wax, jacket view), floating
  quote card with price, ship window and quantity; phone strip and
  bottom bar. Review lists what is missing, itemised quote with basis
  badges, deposit, lead time, ERPNext touchpoints on the simulated
  order. Disabled-not-hidden options with reasons.
- Mastering choice: none, in-house vinyl mastering (5,000 THB a side,
  default), or partner studio (Brandenburg Mastering, Amsterdam, example,
  not contracted) at 60 USD a track (team figure), replacing the in-house
  line.
- Same R list and quote() as artist-order: defaults reproduce 37,836 THB
  per title and the per-copy figures; new lines (repress stamper,
  colour effects, printed inner, finish, obi, bag, shipping) are
  estimates.
- artist-platform.md: the page and the mastering choice; README, landing
  page and site/build.sh entries.
- Checks: pw_order.py 96 checks (parity, partner mastering, 15 steps at
  1440/1024/768/390 dark and light, disabled force-clicks, render sizes
  and fills, uploads, audio readers, share link, place order).

grabowski 69f8392a23 Optical QC: plate every 5 records, how plates avoid scratching 
User, 19 Oct 2026: one plate every 5 records; how do we make sure the
plates don't scratch the records.

- Plate every 5 (10 per 50-record stack, ~15 kg a stack).
- Scratch rules: groove-guard profile keeps grooves off the plate (QRP);
  plate flat, larger than the record (306 to 310 mm), deburred; clear
  anodised (cost estimate, CNY 16 to 28/m2 China reference); vertical
  handling only; no grit (trimmer extraction, ionised blow-off and wipe
  on return, covered carts and racks); numbered plates, monthly check;
  station compares scratches on plate faces vs record faces.
- About 700 plates for a 24 h queue (25 sheets, THB 245k to 315k cut,
  + 35k to 105k anodising, estimates); 200 to 260 for 8 h.
- Plate trial adds bare vs anodised and the scratch comparison.
 2026-10-19 12:37:28 +07:00
grabowski 5bdb013449 Optical QC: stacks of 50, aluminium cooling plates cut locally 
User, 19 Oct 2026: stack records with spacers; the plates are aluminium
and should be cut locally.

- Where it sits: 50 records a stack (Cascade), a flat aluminium plate
  every 10 records to start (MY45; Mobineko uses one per record; the
  Classic handles plates itself), full discs not ring spacers.
- Plates: 5052 (5083 if anodised), 3 mm, diameter and hole to Newbilt's
  drawing; 28 per 1220 x 2440 sheet, sheet about THB 8,300 ex VAT
  (OneStockHome, 3003), THB 350 to 450 a plate cut and deburred
  (estimate); fibre laser or waterjet, Chiang Mai shops listed; deburred,
  flatness check, kept clean. About 350 plates for a 24 h queue
  (THB 120k to 160k), 100 to 130 for 8 h.
- Spiral cooling tower considered and not taken (full queue USD 75k to
  120k for 8 h, dust, no stack weight); a 30 to 60 min spiral stays a
  later option.
- Next steps: Newbilt plate drawing; new plate and settling trial
  (plate every 5/10/25, warp at 1 h and 24 h).

grabowski c939ba1fbb Optical QC control: QiTech Control library and shop 
User, 19 Oct 2026: check github.com/qitechgmbh/control and
shop.qitech.de/collections/ethercat.

- QiTech Control (LGPL-3.0, Rust on an EtherCrab fork, NixOS, runs
  QiTech's own machines): plan now uses its EtherCAT library qitech_lib,
  pinned, as the layer under our station service; not the full Electron
  app. It has DC SYNC0, SDO/PDO handling, EK1100/EL2809/EL3021/EL3024
  drivers and a CiA402 MINAS A6 servo driver to copy for the A6-EC.
  Drivers to write: EK1101, EL1809, EL3152, EL5101, A6-EC (upstream).
  Kernel: start from QiTech's tested settings (6.18, preempt=full,
  isolcpus 2,3); 6.12 PREEMPT_RT stays the fallback for IgH.
- QiTech shop (new Beckhoff stock from an insolvency, ships worldwide):
  EK1101 EUR 85.13, EL1809 EUR 16.53, EL2809 EUR 41.03, EL9011 EUR 1.76
  replace the geizhals offers, EUR 207.57 less. TwinSAFE and Beckhoff
  STO servo terminals noted, not taken.
- EtherCAT parts EUR 1,684 to 1,897 + 2 servo kits (THB 72k to 80k);
  bench parts about THB 56k; spare coupler/DI/DO now stocked.
- BOM total USD 16,671 to 32,681 (THB 0.55M to 1.08M).

grabowski face699a28 Optical QC: EtherCAT control plan with geizhals.de prices
Deploy test site / deploy (push) Successful in 57s
Details 
User, 19 Oct 2026: plan the current EtherCAT setup, keep the 100 W servo,
check prices on geizhals.de.

- New docs/equipment/inline-qc-control-plan.md: decisions, bus layout
  (drives at the end of the line because the A6-200EC takes control
  power from the main supply), I/O list for EL1809/EL2809/EL3152/EL5101
  and the drive touch probe, PDO and DC notes from the A6-EC manual,
  geizhals.de price table (EUR 1,891.60 to 2,104.39 + USD 246.58 for the
  servo kits, THB 80k to 88k), NixOS/EtherCrab software, safety circuit
  (PNOZ s3, two contactors, dump valve), bench test with pass marks
  (parts about THB 64k, all reused), build order, spares, open points.
- EL3102 replaced by EL3152: the optoNCDT 1420 output is 4 to 20 mA.
- Spindle encoder index goes to an EL5101 instead of the drive touch
  probe; encoder 2,000 to 2,500 pulses.
- BOM: control lines split per part with geizhals.de prices (+30% high
  end for shipping and Thai duty/VAT, estimate); total USD 16,912 to
  33,061 (THB 0.56M to 1.09M). Doc, render caption and fleet calculator

grabowski d26ed7ab3c Optical QC: STO servo version looked at, stay with 100 W 
User, 18 Oct 2026, asked about the A6-EC400H2B1-M17-STO (400 W, STO,
brake, USD 157.91). STO comes only from 400 W; its manual gives no SIL
or PL and no certificate, so it cannot replace the contactor; the brake
holds nothing on a horizontal axis. Recommendation recorded: keep the
100 W kit; if a rated STO is confirmed in writing, take the brake-less
A6-EC400H2A1-M17-STO (USD 129.60) on both axes, 1:2 to 1:3 belt, no
contactor.

grabowski ba1f5fc3a9 Optical QC: EtherCAT control 
User, 18 Oct 2026: use an EtherCAT based system.

- Spindle and conveyor on the StepperOnline A6-EC100L2A1-M17 kit
  (100 W, A6-200EC drive, USD 123.29), spindle through a 1:6 belt in
  cyclic synchronous position, conveyor in cyclic synchronous velocity.
- The A6-EC drive has no divided encoder output, so an RS-422
  incremental encoder on the spindle shaft clocks both line-scans; its
  index goes to the drive touch probe for one angle reference.
- Station controller: fanless N100 mini PC with 2x Intel i226, NixOS
  PREEMPT_RT, EtherCAT master EtherCrab (Rust, MIT/Apache) first, IgH
  (nixpkgs, igc native driver on 6.12 LTS) as fallback; no PLC.
- EtherCAT I/O: EK1100, EL1809, EL2809, EL3102 (warp lasers sampled with
  the spindle position, ~1,000 points a turn at 1 ms).
- Safety stays hardwired (safety relay, contactor; no STO at 100 W).
- Edge PC with the GPU stays off the real-time loop.
- BOM: drives, encoder, controller and I/O lines with sources; total
  USD 16,112 to 32,938 (THB 0.53M to 1.09M). Next step: EtherCAT bench.
- Investor render: cabinet and outfeed labels.

grabowski cf900cf3a4 Optical QC: spindle servo, 100 W StepperOnline A6-RS kit 
User, 18 Oct 2026, asked about the StepperOnline A6-EC100L2A1-M17
(100 W EtherCAT kit).

- The motor fits: torque about 0.02 N m needed at the motor through a
  1:6 belt (0.32 rated); the belt brings the load inertia (about 25 to
  35 kg cm2, estimate; record 20.5) to about 28x the 0.03 kg cm2 rotor.
- Take the pulse/RS-485 twin A6-RS100L2A1-M17 (USD 108.78): its drive
  outputs the encoder as divided A/B/Z pulses for the line-scans and
  takes pulse/direction from the planned PLC. The EtherCAT drive has no
  divided output (A6-EC manual, CN1: 5 DI, 3 DO) and needs an EtherCAT
  master.
- inline-optical-qc.md: spindle servo paragraph, sensor table, BOM
  group; BOM line 109 to 250 (was 300 to 700). Total USD 16,073 to
  32,734, THB 0.53M to 1.08M.

Deploy test site / deploy (push) Successful in 55s
Details 
User, 18 Oct 2026: for now one QC station for both machines; let the
records cool in a queue before testing them.

- inline-optical-qc.md "Where it sits": launch setup. Spindle stacks
  from the Duplex system and the Classic, labelled at the press (press,
  stamper set, first and last cycle), cool in FIFO racks (24 h accepted
  practice, 8 h at the shortest, Stamper Discs; about one day of output,
  2,800 to 3,100 records); the finishing operator feeds the station from
  the cooled stacks. Gains: warp and centring measured on settled records
  (the release value), one station instead of two, no Classic unloader
  change, no warm-record sag or thermal camera. Cost: defects found hours
  later, covered by the Duplex operator, per-cycle telemetry and an early
  lane for the first records of each run and after stamper changes.
  Record key from the stack label and stack position, checked against the
  run-out stamper number. Capacity 10 to 12 a minute against 5 to 6:
  one station to about two Duplex systems and two Classics. A station at
  each press stays the later option. Cost table, open points, infeed row,
  thermal camera note and the Newbilt question follow.
- Fleet calculator: the per-press stations and the release station are
  gone; the finishing block shows the cooling racks with record stacks
  and the one optical station by the corridor glass; tooltips, corridor
  and conveyor texts; machine park back to its legend, finishing box
  "cooling, QC, packing".
- quality-automation.md layer 1, digital-factory.md QC row,
  process-flow.md stage 6, site-candidates.md block ground floor,
  crane-workshop-tours.md tour stop 6.
- Investor render: infeed label "the operator sets each cooled record
  down".

Checks: node --check; pw_bp_calc.py 0 fails; pw_iso_view_check.py OK;
info for every data-id at all presets, levels and rotations; GF nodes
2,414 at the full preset; zoomed shots in two rotations.

- Fleet calculator, isometric plant view: qcStation() draws the concept
  station (1.9 x 0.65 x 1.5 m: aluminium conveyor table with the two rim
  belts, light-tight tunnel, stack light, record on the infeed, reject
  bin) in front of the operator in every Duplex cell (after the trimmer)
  and at the unload side of every Classic, in the hall and in phase 2;
  own ids qc-duplex-n / qc-classic-n with tooltips from
  inline-optical-qc.md (Classic hand-off open with Newbilt). Cell floor
  extended to take the bin.
- The finishing block's end-of-line optical station becomes the release
  inspection: the same station measuring cooled samples (records settle
  ~24 h); corridor, block and conveyor tooltips reworded.
- Machine park schematic: a QC bar in every Duplex cell and Classic, an
  "inline QC" legend entry; the legend moved to the bottom of the hall
  box (it collided with the hall heading).
- Docs: inline-optical-qc.md (release station location, plant view),
  site-candidates.md block ground floor, crane-workshop-tours.md tour
  stop 6.

Checks: node --check on all scripts; pw_bp_calc.py 0 fails;
pw_iso_view_check.py OK; every data-id has info at all presets, levels
and rotations; legend clear of cells and heading up to 30M records;
zoomed shots in both themes and two rotations. GF node count at the full
preset 2,523 (was 2,388), 8M records ~2,980; rebuild under 60 ms.

  header. The business plan renders pin setRotation(1) already.
- Drag pans at fit as well (was only when zoomed in); grab cursor at
  every zoom, grabbing while dragging. On touch screens the fitted view
  keeps vertical swipes for page scrolling (touch-action pan-y), so a
  horizontal drag pans; once zoomed in every direction pans, as before.

User, 18 Oct 2026: use real 40x40 profiles, make a render with text
pointing out the parts to show the investor; the ring lights looked
like they were floating.

- build_station.py: frame drawn from the real 8-slot 40 series section
  (profile_shape: slots, centre bore, corner cavities; 40x80 with centre
  cavity) and 24 cast angle brackets; top beams now butt between the
  uprights; label-camera posts moved beside the cameras so both ring
  lights clamp straight to them; top line-scan on a side post with
  visible camera plate and light hangers; slide strips on carrier angles,
  pulley axles, end-stop posts, presence-sensor brackets, backlight post,
  cabinet on base crosses, chute on two supports and clear of the rail,
  pneumatics rail, stack light on the back upright, touch screen on the
  front end upright. A connectivity check at the end lists any part that
  does not reach the floor through touching parts: none.
- render_annotated.py (FreeCAD): front three-quarter view, camera backed
  off so nothing is clipped, no navigation cube or preselection, label
  positions projected from the camera and checked with marker renders.
- annotate_render.py (Pillow): title, 16 labels in two columns, leaders
  assigned so none cross -> inline-qc-station-annotated.png.
- render_station.py: same camera and preselection fixes; all six views
  re-rendered.
- BOM: 32 m of 40x40 in 45 pieces; total still USD 16k to 33k.

  bin, outfeed stop, cabinet, PLC, NixOS edge PC, HMI, stack light.
- render_station.py renders six views (open and closed iso, front, plan,
  inspection detail and elevation via clipped temporary documents).
- inline-qc-station-bom.csv: 32 lines with sources; USD 16k to 33k per
  station without the thermal camera.
- inline-optical-qc.md: new section "The station setup" (flow table,
  inspection zone, cycle ~5 to 6 s, control, BOM by group, open points);

User, 17 Oct 2026: "only put solar on the factory, prepare the other
buildings for solar, option a and b should operate on biomass".

- Steam: two 500 kg/h biomass modules (Getabec class, 6M to 10M THB) plus
  a fuel store and handling block (1M to 2M, estimate) in both plans; the
  electric bank becomes the alternative. ~0.67M THB of fuel a year against
  ~4.9M for electric steam; grid demand ~264 kW instead of ~980 kW.
- Solar: ~520 kWp on the factory roof (the biomass-case optimum is ~500 to
  550 kWp, hourly sketch in sustainability.md "PV size with biomass
  steam"); office roof and parking canopies built PV-ready (~120 kWp
  later). ~87 % used on site, ~61 % of the plant's electricity.
- Calculator: biomass default, bFuel row, pvKWp 520, pvSelf 87, iso fills
  the factory roof first and shows the other roofs as PV-ready.
- Numbers: launch plant ~168M / 232M / 296M with contingency; Plan A
  ~182M (~2M above 180M: the Chinese-route lever priced only electric
  boilers; a Chinese biomass quote is the way back), Plan B ~217M (label

- Permits (rooftop solar no factory licence since 28 Dec 2024, ERC
  exemption under 1,000 kVA, PEA zero export) and PPA discounts sourced
  in sustainability.md.

BOI correction
- Announcement 3/2568 (in force 1 July 2025) ended BOI promotion for
  solar installations; only the battery may qualify (12M THB per MW cap).
  Removed the "BOI solar measure" from boi.md, total-investment,
  revenue-model, sustainability, site-candidates and both plan versions;
  Plan B's case for owning the array is the PPA bill it avoids
  (~0.07M USD a year).

Open source (user, 17 Oct 2026)
- digital-factory.md "Open source throughout, and working with other
  plants": everything we run and build is open source on NixOS, our code
  published (licence to decide), vendor firmware the stated exception;
  later the stack and factory-automation services for other pressing
  plants, not in the revenue.

  (300 kW for 5.4M THB), Deye hybrid inverter retail (160,500 THB per
  50 kW).
- Battery 271 kWh, now installed: 2.0M to 3.5M THB (was the bare Gobel
  list price, 1.4M to 2.0M, which matches DEDE's 5,000 to 7,000 THB/kWh
  for LiFePO4); adds enclosure, fire protection, controls and installation,
  below CapSolar's 12,000 to 15,000 THB/kWh for a fully installed factory
  BESS because the hybrid inverters do the conversion (estimate).
- Utilities baseline 27.57M to 47.50M THB; launch plant ~160M / 222M /

- Plan B now starts like Plan A with one Duplex system and one Classic,
  but takes none of the six levers: owned solar and battery (with the BOI
  solar measure), the full metrology stack, the visitor corridor, cassette
  and CD-R, the bought crane and Thai-supplied utilities (user, 17 October
  2026). ~193.8M THB before the reserve, ~209M with it (~150M to 268M),
  ~32M (~18 %) more than Plan A; the second Duplex is a growth step from
  revenue in both (~15.4M THB, estimate).
- total-investment.md "Two plans" re-based (heading and anchor now
  "B at ~210M THB", README and roadmap links updated); revenue-model.md
  operating pictures: same volume and EBITDA as Plan A, depreciation on
  Plan B's capital (operating profit 1.26M USD central, payback ~3.7 yr);
  the extra earns nothing in the modelled table, which the docs say.
- Calculator: Plan B preset = the launch plant with contingency kept out
  (EBITDA 2.07M USD, cash payback year ~4.3, IRR ~21 %); budget card marks
  180M and 180M plus 25 %; preset label "Plan B (~210M, all in)".

  business plan calculator, drawn with each version's own preset: the
  cover (roofs, no labels), Figure 8 the site from above, Figure 9 the
  ground floor cut open, Figure 10 the press hall close up. The FreeCAD
  aerial render, the Mueang Chi site plan and the hall layout sketch are
  no longer in the plan; the captions say the calculator draws the Payap
  scenario model while the 6.2 text and zone table are the Mueang Chi
  hall.

  artist platform" with six screenshots of the demos: the plant overview
  (simulated SCADA), the factory console press floor and its ERPNext
  link, the artist ordering offer, fan funding and the record passport.
  Simulated data is marked as such; the platform name stays undecided.

- Plan A: the launch plant with every machine and six cost levers, ~177M
  THB with the ramp-up reserve, no contingency. Plan B: the second Duplex
  at launch, five presses, ~224M THB on the same basis. Each version reads
  as a complete plan with one table comparing it with the other; the
  216M investor-question text is gone, Pheenix is priced at OMS's
  reference plus 20 %.
- Calculator renders in both documents, each from its own preset: the
  plant at a glance (Figure 4), the budget check (Figure 5) and ten years
  of cash (Figure 6), in docs/renders/calculator/.
- Calculator budget card: the verdict and third KPI now name the tightest
  budget the midpoint fits (Plan A: 3.3M to spare under 180M; Plan B:
  0.8M under 225M) instead of always 225M.
- Fixes: CD replication cross-references point to section 4.10; the

User (October 2026): price the Pheenix galvanics line at OMS's reference
plus 20 %, and work on a new business plan in two versions, one at
roughly 180M THB and one at +25 %; the plans do not include contingency;
Plan A keeps every machine and uses cost levers only.

- total-investment.md: Pheenix block 324k to 445k USD (OMS 4-cell wet
  room with know-how transfer, EUR 234k to 321k, plus 20 %; was 320k to
  650k estimate); launch plant now ~161M to 285M THB with contingency,
  midpoint ~223M. New section "Two plans": Plan A = launch plant with
  solar PPA, metrology launch tier, corridor later, cassette and CD-R
  later, rented crane, Chinese boilers and compressor: subtotal ~161.7M
  + ramp-up reserve 10 to 20M = ~177M THB (127M to 226M). Plan B = second
  Duplex at launch (five presses), everything in: subtotal ~209.2M +
  reserve = ~224M THB (162M to 286M). Contingency listed as not in
  either price (~24M / ~31M at 15 %). The 180M / 216M answer marked
  superseded.
- revenue-model.md: operating pictures of both plans at 60 % specials.
  Plan A central EBITDA 1.73M USD, operating profit 1.34M, payback ~3.1
  yr on the plan price; adverse loses money. Plan B (1.0 / 1.25 / 1.5M
  records) central EBITDA 3.14M, operating profit 2.63M, payback ~2.2 yr;
  adverse just covers depreciation; needs ~1.25M records sold.
- Calculator: Pheenix price basis "OMS +20 %" and "OMS directly"; new
  contingency switch (in the total / shown separately); presets Plan A
  and Plan B (replace "investor levers" and "five-press"); budget card
  against 180M and 225M.

EUR) and a language selector for Thai on the make-a-record demo.

- Top bar: one currency control (replaces the THB/USD switch on the
  price step) and an EN / Thai control, visible from step 1; both persist
  (localStorage, #cur= / #lang= in the URL, hash wins). Prices stay
  computed in THB: USD = THB / 33, EUR = THB / 38.115 (1 EUR = 1.155
  USD); the fan price is entered in the chosen currency and stored in
  THB, the campaign rule max(100, break-even) unchanged.
- Thai: every visible string, tooltip, aria label, file check, quote
  line, production update, passport, investor note and tour caption
  (dictionary T = {en, th}, t(key, vars), data-i18n attributes; 636
  keys), system Thai fonts, Thai dates with Gregorian years, and a footer
  note that the Thai is a draft translation for review. Template PDFs
  stay English (Helvetica has no Thai glyphs).
- Top bar wraps to two rows below 1000 px (steps were cut off between 761

Deploy test site / deploy (push) Successful in 44s
Details 
User (October 2026): "change the hall layout" after the finding that the
60/40 floor split leaves the Classics about half loaded at 60 %+
specials (specials run only on the Duplex systems).

- Press hall now keeps five Duplex bays (four along the visitor
  corridor, the fifth at the head of the second row) and four Classic
  positions: 550 + 200 = ~750 m2 of ~870 m2, ~73/27 by floor, 10 to 4 by
  presses; launch plant fills one of each, growth adds Duplex first.
- Full hall: ~2.9 to 4.4M records a year at 60 % specials, Classics ~80
  to 100 % loaded (60/40 gave ~2.3 to 3.6M); ~3.2 to 4.4M at ~20 %;
  fourteen presses as before: ~2.1 to 2.5 t/h steam, up to ~1.8 MW
  cooling, a utility phase of its own.
- pressing-line.md, scale.md, site-candidates.md, crane-workshop-tours.md,
  roadmap.md, README (FreeCAD model still the earlier layout, not
  redrawn); calculator preset "Full hall (5 D + 4 C)" and ladder; plant

grabowski b3e8e4272b Specials share 60 %+: revenue model, calculator and business plan re-based
Deploy test site / deploy (push) Successful in 52s
Details 
User (October 2026): "lets say 60+% special prints" (the plant focuses on
special prints, not mono colours).

- Specials (splatter, marble, colour effects) run only on the Duplex
  systems, so at 60 % the Duplex sets the launch plant's output: ~0.58 /
  0.74 / 0.90M records a year (was 0.71 / 0.84 / 0.97 at ~20 %), the
  Classic at about two thirds load. Full 60/40 hall: ~2.3 to 3.6M (Duplex
  -limited, Classics about half loaded); five-press fleet unchanged. A
  hall balanced by output at 60 % would give Duplex ~70 to 75 % of the
  floor (estimate; noted, not applied).
- Blended price 3.76 / 4.49 / 5.27 USD (standard 3.40 / 3.80 / 4.25 plus
  the 0.60 / 1.15 / 1.70 specials premium on 60 %). Launch operating
  picture: revenue 2.28 / 3.65 / 5.41M USD, EBITDA 0.23 / 1.73 / 3.79M,
  operating profit -0.66 / 1.21 / 3.46M, payback ~3.8 yr central,
  break-even ~0.25M records; adverse needs ~1.1M records to cover
  depreciation. Specials' extra direct cost (coloured compound, purge,
  trim only into black) is not in the cost table yet: flagged as an
  upper bound until compound quotes.
- Calculator default specials share 20 -> 60 % (planning rates keep the
  launch plant balanced at 850k: revenue 4.14M, EBITDA 2.07M, payback
  3.3 yr, cash payback year ~4.8, IRR ~18 %).
- revenue-model.md, scale.md, pressing-line.md, README; business plan
  draft 0.2 rebuilt (sections 1, 4, 9, risks).

Deploy test site / deploy (push) Successful in 46s
Details 
User (October 2026): "the factory should have more space for duplex
setups than classic, we will mainly focus on special prints and not mono
colours plan it to be 60/40 duplex classic".

- Press hall (~870 m2) planned 60/40 by floor: four Duplex bays along the
  visitor corridor and six Classic positions in the second row (440 + 300
  = ~740 m2 at 110 / 50 m2), the rest open for mould carts and staging;
  the launch plant fills one of each, growth adds Duplex systems first.
  Replaces "room for ten more Classics".
- Full hall: 8 semi-automatic presses + 6 Classics, 57/43 by press count,
  ~1,250 to 1,410 records/h gross, ~3.6 to 4.7M a year on the scale.md
  basis (was 4.7 to 5.8M for 2 Duplex + 11 Classics); ~2.1 to 2.5 t/h
  steam and up to ~1.8 MW cooling, still a utility phase of its own.
  By hourly output the six automatic Classics still press more than the
  eight semi-automatic presses (estimate).
- pressing-line.md, scale.md (capacity table, utilities), site-candidates
  .md, crane-workshop-tours.md, roadmap.md, README (the FreeCAD Payap
  model still draws the earlier layout; noted, not redrawn).
- Calculator: preset "Full hall 60/40 (4 D + 6 C)", fleet ladder Duplex
  first (1+1, 2+1, 3+2, 4+3, 4+6) plus the same floor Classic-led (2+11)
  and Duplex-only (7+0) for comparison; plant view reserves 4 Duplex
  bays and 6 Classic positions.
- Business plan draft 0.2 rebuilt (capacity table row, plot fit, layout).

Checks: renderer 720 checks pass (node budget 2,700 for the Duplex-heavy
stress preset, 60 fps), calculator regression 0 fails, level selector and

User feedback on the isometric view (October 2026):
- "the production hall is missing toilets": two sets. At the staff
  entry: women 2 WC, men 1 WC and 1 urinal, an accessible WC, basins.
  At the east end of the back aisle in the finishing block: women 2 WC,
  men 1 WC and 1 urinal, basins (proposed, not yet in the parametric
  plans). site-candidates.md gets a Toilets bullet with the Thai minimum
  (Ministerial Regulation No. 39 B.E. 2537, table 2; separate toilets for
  men, women and disabled staff under the welfare regulation B.E. 2548).
- "the door and the corridor is not aligned": the covered link now lands
  on doors at both ends, centred on it (factory entrance at the start of
  the visitor corridor, office lobby door on the north face, windows
  cleared); the corridor glass starts after the door; the stray staff
  door with no path is gone; the link deck ramps up to the factory floor.
- "we also dont need a extra trimmer with the optical, this is included
  in the duplex and the classics": the finishing block keeps only the
  optical inspection station; site-candidates.md, the tour route and the
  process flow say the presses trim inline.

User feedback on the isometric view (October 2026):
- "a light pole in the middle of the truck apron": a PAVED list of the
  drive areas (gate road, aprons, east road, lane, access road, car
  park, yard); every lamp now stands on a kerb or verge (the apron lamp
  to the south kerb, three more moved off drive areas, one added on the
  east road); one LAMPS list feeds poles and light pools.
- "the office building also has 2 levels, can we make a selector for GF
  1 2": the Roof / Inside toggle becomes GF | 1F | Roof. 1F shows the
  office first floor (+4.0 m: offices, meeting and training, meeting
  room, IT and server, toilets, pantry, flexible room, stair and lift)
  and the finishing and print block's upper floor (+3.8 m: print room in
  reserve, print stock, packaging materials, stair and goods lift), the
  rest ghosted. Office ground floor re-split after the floor plans
  (site-candidates.md). setMode('inside'/'roof') still works; new
  setLevel / getLevel / onLevel; the level survives calculator updates.
- "the pipe bridge to the pump and HX room also stops mid air": both
  pipe bridges now drop down the wall faces at the factory and at the
  yard building to low-level wall sleeves, with a second support post.

Checks: renderer 720 checks (presets x GF/1F/Roof x 390/1024/1440 x

Deploy test site / deploy (push) Successful in 47s
Details 
User feedback on the isometric view (October 2026):
- "the cars are above the car park roof": cars and scooters were their
  own sprites and the depth sort put some above the canopy; they are now
  drawn inside the canopy sprite before the posts and the roof, so the
  roof always covers them in every rotation.
- "a light pole in the middle of the yard": the two yard lamps at the
  service-lane edge (one in front of the boiler hall) move to the yard's
  back fence; one LAMPS list feeds both the poles and the light pools.
- "add solar panels to the car park": the car and scooter canopies now
  take PV first (107 modules, ~48 kWp; construction RFQ has canopy PV),
  the factory roof the rest (560 of 667 modules at 300 kWp); canopy
  tooltips give their kWp.
- "arrange the pvc storage outside to be black, red, yellow": the silos
  read black, black, red, yellow from the default north-east view.

Renderer checks rerun (288 + functional, no failures); calculator

New card "The plant at a glance" at the top of the plant and business
plan calculator: an isometric SVG scene (CNXIso, inlined with its iso-
prefixed CSS) of the Payap-scenario site driven by the calculator state:
Duplex systems and Classics (r.D, r.C; overflow into the phase 2
building), galvanics in-house or "stampers bought in", cutting in-house
or "cut abroad", metrology tier, cassette and CD-R benches, solar buy /
PPA / none (300 kWp, 271 kWh battery), electric or biomass steam (fuel
store, chip pile, smoking stack), boiler and chiller modules out of the
four positions each (r.nb, r.nc), crane, visitor corridor.

Roof / Inside cutaway, four rotations with a north arrow, zoom, pan,
pinch, tap for figures from the docs; dusk in the dark theme, day in the

  price points (ResurRec and Record Industry), anatomy rewritten for
  Sillitoe, Pheenix, Sibert, Duplex + Classic, lead times without bridge
  stampers, new 4.8 artist platform, cassette 4.9, CD 4.10.
- Part B: traceability with ERPNext as system of record, metrology launch
  tier as the investor's choice, QC, efficiency (PEA tariff, utility
  modules, fuel open, Chinese boilers and DIW rules), site (Mueang Chi,
  Payap zoning result), building blocks, safety, BOI and licences with

Checked October 2026 on the investor's budget question. New
docs/suppliers/china-utilities.md: boiler makers (ZOZEN, Sitong,
Fangkuai, Taiguo, Yuanda, Yongxing, Taishan, Nobeth) with fit for 500
kg/h at 1.25 MPa, claimed certificates, Thai references and listing
prices; the Thai rules for an imported boiler (MR and MOI notification
B.E. 2549: ASME/JIS/EN or equivalent, certification-body verification,
once-through relief does not reach 10.5 bar, licensed controller, annual
inspection); compressor makers with Thai offices (Kaishan, Denair) and
sizing; hydraulic pump sets and accumulators (Huade, Yuci, Hengli, WMD,
Renowell, Inovance, NXQ makers), the shared-ring-main risks and Thai HPU
builders; duty and freight; open RFQs.

Result: about 2M THB at the midpoint (~2.5M with contingency), ~1 % of
the 216M target, mostly the boilers; Newbilt aggregates stay Newbilt's.

grabowski 553b4a93d1 Launch plant roll-up and the investor's 180M THB question 
Decided (user, October 2026): the plant launches with everything in one
capital round, commissioned in sequence: one Newbilt Duplex system, one
Classic, a Pheenix galvanics line with ZLD water, the Sibert line, a
Sillitoe cutting room, and the modular steam and cooling plant (2 x 500
kg/h boilers, 2 x 250 kW chillers, rooms for four each). No bridge
stampers, no outsourced cutting; cassette and CD-R stay; the second
Duplex and further Classics are growth options, not in the investment.

total-investment.md: new 'Launch plant' roll-up, 4.9M to 8.9M USD,
161M to 292M THB incl. 15 % contingency (midpoint ~227M), with what is
left out (ramp-up reserve ~10-20M THB, CD replication, financing, FX,
archive shelving) and the BOI assumption. The investor's question (180M
THB, maybe +20 % = 216M): fits at the low end only; at the midpoint four
levers that keep every machine (solar via PPA, metrology launch tier,
galvanics near OMS's reference, visitor corridor later) give ~193M, plus
reserve ~203-213M, inside 216M; 180M needs low quotes. The quotes that
decide it: Newbilt (Duplex, Classic), Pheenix galvanics, building with
soil test, metrology. Old full vision and phased entry marked superseded
until the mirrors are re-based.

Utilities CSV: chiller bank two modules (4.9-7.9M THB), boiler note for
B-1 and B-2 at launch, ZLD and DI rows now launch scope (carried with
galvanics); baseline 28.47M-48.73M THB. README project status.

User request (October 2026): the order tool needs a thin / thick spine
selection, templates for the jacket and label upload, and must accept AI
and PDF files.

Both artist demos (artist-order, make-a-record):
- Spine: thin 3 mm (one record) or thick 5 mm (two records, or a thick
  insert); a double album in a single jacket takes 5 mm, thin is then
  disabled; 7", gatefold (7 or 9 mm) and own jacket disable the row with
  the reason. Quote line 'Thick 5 mm spine' (R.spine 12 / 10 THB per
  copy, estimate from QRP 0.90 vs 0.55 USD and Kudos 137.50 GBP/order).
  Mock-up draws the spine edge to scale; caption names it.
- Templates: vector PDFs written in the browser for the current choice:
  jacket spread (back, spine, front; 633/635 x 315 mm for 12" from
  Mighty Media Discs), gatefold with an inside page, labels with a page
  per side and the dinked hole; trim and bleed boxes set, 3 mm bleed,
  5 mm safe area, folds, crop marks, guidance notes.
- Uploads accept PDF, AI (PDF-compatible) and images. PDFs are read in
  the browser (object streams inflated with DecompressionStream): page
  boxes, pages, PDF/X, creator, colour spaces, font embedding; checks
  against the chosen spine (a 5 mm spread on a 3 mm order is flagged),
  bleed, CMYK, fonts; old PostScript-only AI files are refused with the
  fix. Image spreads are measured the same way. Preview via pdf.js
  (jsDelivr, loaded only when a PDF arrives); the front panel goes into
  the mock-up.

grabowski a101c9f7db Factory console: ERPNext link page and ERPNext documents on orders
Deploy test site / deploy (push) Successful in 45s
Details 
Follows the decision that the whole plant runs ERPNext and every tool
we build interacts with it (e12ad2e).

- New page #erp (nav: ERPNext): every posting the floor makes, derived
  from the same event log: sales orders in by webhook, work orders,
  job cards per station, serial numbers for lacquers, fathers and
  mothers (warehouse Archive), purchase receipts, quality inspections
  and stock entries per compound batch, manufacture entries per run,
  downtime entries per stop, delivery notes and invoices. Outbox status
  per row (sent within a minute, held during the nightly backup
  01:00 to 01:15), KPIs, who-owns-what table, counts by document type.
  Rows use fixed ch grid columns; on phones a two-line row.
- Order page: ERPNext card (customer, sales order, work order with
  produced quantity, job cards completed, batches, delivery note and
  invoice). Work order page: its job card, quality inspection or asset
  maintenance log.
- Names follow ERPNext's default naming series and are simulated;
  nothing uses the simulation's random stream, so the seed is unchanged.
- Phones: the nav strip scrolls the current tab into view. Work order
  IDs on the order page no longer wrap (wider fixed column).

digital-factory.md demo paragraph. Checked: node --check, Edge dark and
light at 1440/1024/390 (no overflow, no page errors, rows aligned), and
the pw_fc, pw_wo and pw_feed regressions.

grabowski e12ad2ed7b ERPNext runs the whole plant; every tool we build integrates with it 
Decided by the user (October 2026): the whole plant runs ERPNext, and
all tooling we develop has to interact with it.

digital-factory.md: standing decision in the summary; decision 10
(ERPNext owns the business documents, the factory application owns the
floor; ERPNext names are the shared keys); new section 'ERPNext: the
plant's ERP' with the ownership table (customers, prices, sales orders,
items and BOMs, work orders and job cards per station, batches and
quality inspections per compound lot, serial numbers for metal parts,
downtime entries, delivery notes, assets, accounting, payroll vs. cycles,
per-record inspection, genealogy and the hash-chained log staying in the
factory application), the integration rules (one typed Frappe REST
client in cnx-factory, an integration user per tool, webhooks in,
transactional outbox with idempotent postings so the floor never waits
on the ERP, business-sized postings, customisation as a Frappe app in
Gitea, nightly reconciliation, no public ERPNext endpoint, new tools use
the same client), hosting on NixOS (no nixpkgs module, NixOS/nixpkgs
#241921; Avunu frappe-nix as the start, frappe_docker as
oci-containers fallback; MariaDB + Redis; vinyl-erp on site behind the
gateway proxy; OIDC sign-on; upgrades on a restored copy), Thai
localisation (Ecosoft erpnext_thailand: VAT, WHT, PND, billing notes;
Ecosoft as partner to quote; payroll and BOI reporting to check),
phasing (dev ERPNext now; accounting and assets from the first capex
invoice; manufacturing at commissioning) and estimates. ERPNext added
to the architecture diagram, services, machines (vinyl-erp), module
list, backup, cost, build order and open decisions; the old 'ERP out of
scope, decide after launch' line replaced.

artist-platform.md: price list, customers, sales orders, campaign
pledges as payment entries, through the plant's outbox. traceability.md:
one ERP, one set of keys. README summary. total-investment.md added
scope: ERPNext (to quote, not in the sum, no licence fee).

Added at the user's request (October 2026): LPI Rack Range (Thailand)
Corp., Ltd., Bangkok head office, plants in Bangplee Industrial Estate
and Bangpla (Samut Prakan); office mobile shelving for documents, pallet
racking (selective, drive-in, mobile, shuttle, pallet flow), picking
shelves and mezzanines, mould-and-die racking, mini-load AS/RS; no specs
or prices published (lpi.co.th, checked October 2026).

grabowski 4f02d9a7a9 Archive room: mobile shelving for the father and mother archive
Deploy test site / deploy (push) Successful in 43s
Details 
Planned (October 2026, user): the archive in the office gets mobile
archive shelving, A-Z Solutions (Vienna) as the reference
(a-z-solutions.eu, checked October 2026: hand wheel or electric drive,
lockable, rails need early floor planning; no published prices).

facility-security.md, new section under Protecting the irreplaceable:
what it holds (fathers and mothers, ~1,200 to 2,400 parts a year; a
reference pressing per title only as a proposal), sizing estimates (about
0.2 kg per part, ~3 mm and ~75 kg per shelf metre; in the Payap office's
~4 x 5.75 m room two fixed runs, four double carriages and one aisle hold
~150 shelf metres, ~50,000 parts, 20+ years), what it asks of the
building (ground slab at full rating, ~11 kN/m2 under the block; rails in
the screed fixed before the floor finish; geared hand wheel; gas,
climate, leak sensor, access control; barcoded box addresses), open
points (quotes from A-Z and a Thai supplier, storage format from the
galvanics vendors, fathers in a second compartment or off site).

Mirrors: site-candidates.md (office ground floor), phase 1 RFQ (archive
keeps the full slab rating if the slab is zoned), digital-factory.md
(archive location as box and shelf position, sets per mother),
equipment-suppliers.md (section 8 entry), total-investment.md added scope
(to quote, not in the sum).
 2026-10-16 11:18:09 +07:00
grabowski 475623e9f2 Archive the father as well as the mother; how many represses a mother carries 
Decided (October 2026): the plant keeps the father and the mother of every
side. production-timeline.md (repress section) records the decision and the
rule of thumb with sources: about 10 stamper sets per mother before it
degrades (Third Man Pressing FAQ, a Nashville plater via WPLN), fewer in
quality-minded sources (5 VinyLab, 6 to 8 Stereo Review 1962); a father
grows about 5 to 10 mothers. So a mother covers roughly ten represses
(10,000 to 20,000 records a side) and a worn one is replaced from the
archived father without a new cut. galvanics.md: 4 archived parts per
title, ~1,200 to 2,400 a year; new open question to all galvanics
candidates (sets per mother, mothers per father, storage).
artist-platform.md repress paragraph.

Demos: make-a-record and artist-order say father and mother are archived;
factory console archives the father on represses too, counts stamper sets
per mother (shown in the genealogy and the customer's metal card), and the
metal archive counts fathers and mothers.

grabowski 1cceedc8a4 Factory console: inspection feeds in fixed columns
Deploy test site / deploy (push) Successful in 45s
Details 
The live inspection feeds (floor, quality, press, customer's latest
copies) were one run-on string, so a shorter press ID (C1 vs D1-A)
shifted everything after it and the cycle time showed twice. Each row
is now a grid of fixed columns sized in characters of the mono font:
time, stamper, press, order, result, with a header row (the row keeps
the mono font so its columns match; only the labels change font). On
phones the order column (factory) or press column (customer) drops.
The full record key stays in the stamper cell's tooltip.

Work order cards: station chip left, work order ID right-aligned in the
header, the assignee moves to the time line, so card headers no longer
shift with the ID length.

grabowski f9b8407561 Factory console: work orders for the operators
Deploy test site / deploy (push) Successful in 51s
Details 
New "Work orders" section in the factory console (#work), derived from
the same simulated records as the rest of the page, one work order per
station and job:
- order stages: mastering, lacquer cutting, electroforming, stamper prep,
  test pressings, press run, packing, dispatch
- stamper changes (planned when a set nears its life, in progress during
  the change), fault clearing on a stopped press (maintenance)
- material lab: lab gate per compound lot, release test pressing, and the
  held lot's re-dry and retest (button starts it)
- audio QC: each sampled copy's listening check

Board: In progress (press floor first) / Next up (planned press runs and
stamper changes with time and press, jobs arriving at the next station)
/ Done today, filter per station, KPIs. Each work order opens a kiosk
view: the steps an operator follows (badge in, scan what the step asks
for, with the IDs to scan, confirm), confirmation times and who did it,
the order, lot or press it belongs to, and what it writes to the log.
Order detail lists the order's work orders by station. Mastering and
cutting are booked to the engineers, the lab, QC and maintenance to
technicians, the rest to numbered operators; jobs finishing at night are
booked to the late shift.

README, digital-factory.md demo paragraph and the landing page mention
the work orders.

New page docs/factory-console.html (site /demos/factory/): the factory
application of digital-factory.md on a simulated plant day, with a
switch to the customer portal of the same orders.

Factory console (sidebar: Floor, Orders, Quality, Lab, Metal, Ledger):
- floor: five presses of the launch fleet (two Newbilt Duplex systems,
  one Classic) with the mounted order, live good / rejected counters,
  stamper plays against life, cycle time and steam; KPIs for the day;
  live optical inspection stream with record keys; alerts (stops, lab
  holds, stampers near end of life, listening reviews, long gate waits);
  stations (cutting, galvanics, stamper prep, lab, packing); orders by
  stage; good records per day
- orders list with stage filters and search; order detail with stage
  track, approvals, metal genealogy and stamper metrology, press run
  telemetry, compound lot certificate, rejects by reason, audio samples,
  packing and shipping, and the order's events
- press detail with telemetry sparklines; quality (rejects by reason,
  yield per press, audio comparison); lab (compound lots with results
  against illustrative limits, one lot on hold with re-dry and retest,
  regrind batches, hoppers); metal (baths, mounted stampers, metrology,
  archive); hash-chained event log

Customer portal (four demo customers: pressing now, waiting to approve
the test pressing, in plating, delivered): progress through every step
and the three gates, copies pressed so far with the latest copies and
their record keys, approving the test pressing books the press slot
(greedy plan of the queue gives the start time and press), and a quality
report that fills in step by step: files, lacquers, metal parts with
metrology, test pressings, the compound lot's lab results, pressing and
inspection, listening checks, packing.

Simulation: 60 days warmed up at load (about 0.7 s), then 1x to 3600x.
Stages and durations from the production timeline, Newbilt cycle times,
two shifts 06:00 to 22:00, unplanned stops, stamper life 1,000 to 2,000
plays, audio sampling first-off plus about 1 in 50 (1 in 25 near end of
life), compound lots through the lab gate and release test pressing.
All orders, values and IDs are simulated; limits are illustrative.

Read its prices for a reference 12" LP at 200 / 300 / 500 / 1,000 copies
and for each option worth copying (checked October 2026).

Both artist demos (make-a-record and artist-order):
- audio arrives as digital files, analog tape (+ tape transfer) or a cut
  lacquer (no blanks, cutting or mastering; mastering choice disabled with
  the reason; cutting and mastering stages skipped in the timeline; the
  passport starts at "Lacquer received")
- labels printed, plain white or plain black (credit line; the label
  artwork drop is disabled for plain labels; the mock-up shows the plain
  label)

Deploy test site / deploy (push) Successful in 1m4s
Details 
The artist sets only the fan price; the number of fans needed follows from
it: the plant's 100-copy minimum, or the break-even if that is higher. The
goal selector of 6a62505 is removed from both demos.

make-a-record.html:
- step 4 leads with "Your price to fans" (input, slider from 300 THB,
  presets 800 to 2,000) and a live "You need N fans to press it, X THB in
  pre-orders", plus the price below which the minimum no longer covers
  the costs (about 640 THB at the defaults)
- limited edition is now a switch, off by default; the edition size stays
  visible but disabled until it is on, and switching it on adds the
  numbered edition to the record
- "per title" renamed for end users: "One-off, for this release", "once +
  per copy", "One-off setup", with a note that one-off costs count sides,
  not songs (a double LP has four)
- the tour lowers the price to 500 THB and back to show the fans needed

  as two bars (approvals, then the 7 to 9 week quote)
- fan funding: goal, break-even and what the artist keeps, money rules;
  the campaign on a phone with a pre-order ticker, funded or missed ends,
  production timeline with the artist's approvals, updates feed
- record passport for one delivered copy (stamper, press, cycle time and
  side; stage dates; optical inspection and sampled audio), per
  traceability.md and quality-automation.md, IDs simulated; repress card
- "Investor notes" switch with the business case per step (market

Phased build list for steam, cooling and hydraulics (launch, Duplex 1,
Duplex 2, Classic, options): everything cheap to oversize and costly to
retrofit (rooms, pads, headers and ring mains with a valved branch per
press position, tanks, HX frame, feeders, one sequencer) is built for the
five-press fleet at launch; boilers, chillers and hydraulic pump sets come
in identical modules as presses arrive. The Single 2.1 aggregate is
proposed as the first central pump set; per-branch isolation and filters.

Rooms sized for four modules each (user decision, estimates until vendor
footprints): boiler hall ~18 x 9 m for four 500 kg/h positions (fired case,
AIX DZL0.5 body), open screened chiller compound ~12.5 x 10.8 m with four
pads (250 kW at 40 C ~ Carrier 30RB 080-090), ~40 m2 pump and HX room; the
cooling tower pad of the water-cooled concept is dropped. Yard 178 -> ~379
m2. Four boilers carry ~8 presses with N+1; four 250 kW chillers carry the
five presses with CH-4 as reserve and no growth position unless the pads
take the ~350 kW frame (RFQ option).

The annex row for type 72 in the very high density residential zone
carries the orange "permitted with conditions" mark; the condition as
printed is "ให้ดำเนินการหรือประกอบกิจการได้เฉพาะดัดแปลงหรือซ่อมแซม"
(may operate only for modification or repair). Added verbatim to the

grabowski 3984d0c93b Payap: the point given fails zoning (DPT, checked 14 October 2026) 
Point 18.797678 N, 99.038272 E, queried on the DPT land-use plan map:
Chiang Mai comprehensive city plan in force from 25 May 2026, zone
ย.7-1, very high density residential. The zone prohibits every factory
under the Factory Act except the types in the plan's annex, and
prohibits warehouse and silo businesses.

Annex for this zone: type 107 (CD production, whose definition names
gramophone records and recorded tapes) is not permitted here, only in
the low density residential, special industrial, agricultural land
reform and rural and agricultural zones; type 72 (sound recording,
record players, gramophone records) only for modification or repair;
plastics products and metal plating are not on the list. A record
pressing plant cannot get a factory licence at that point.

Caveats recorded: point, not parcel; DPT data is preliminary, the
provincial office confirms; the pharmaceutical neighbour may be in
another zone or type. Since type 107 is permitted in the plan's low
density residential and rural zones, other Payap land is worth checking
before the lead is dropped.

grabowski cb5809e73c Feedwater heat recovery: economizer, condensate, then HP-1
Deploy test site / deploy (push) Successful in 48s
Details 
The order to investigate for a fired boiler (biomass such as rice
husk, or LPG): first a flue-gas economizer, second as much clean, hot
condensate back to T-1 as possible, third the heat pump HP-1 where the
press return has enough heat and the combined heating and cooling
economics justify it.

- Diagram: new ECON-1 (option, fired boilers only) between the feed
  pumps and the boiler manifold, with a bypass for an electric bank and
  the flue-gas path from the boilers; feed in 90 to 95 C, outlet and
  stack temperature are vendor figures. HP-1 is now drawn as an option
  and labelled the third measure. AT conductivity on the condensate
  return to T-1; off-spec condensate goes to the warm tank.
- Found in Newbilt's offer 240620-04: steam and cooling water share the
  mould channels, with one steam/water outlet valve and steam trap per
  mould, so the condensate is only as clean as the cooling loop. Noted
  in the T-1 detail, sustainability.md and as a Newbilt RFQ question.
- With most condensate returned (about 15 % flashes at atmospheric
  pressure, estimate) the feed tank needs only a fraction of the ~70 kW
  that heating all make-up takes, so HP-1 may not pay.
- RFQ: economizer outlet feed and stack temperature, corrosion limit,
  pressure drop; rice husk ash is high in silica and abrasive, so
  fouling, cleaning, wear protection and a bypass.
- sustainability.md: the order, before the exclusions. biomass.md: new
  "Recovering heat at the boiler".

Checked headless (scripts/pw_sc_check.py): 33 boxes, 20 tags, no
overlap or overflow, no unstyled pipes, no card or page overflow at

Deploy test site / deploy (push) Successful in 47s
Details 
Twenty temperature tags on the pipes, each styled by its basis: green
border for a Newbilt figure, amber for a design target or estimate,
dashed for a value the vendor or a measurement still has to set.

- Newbilt: steam main 10 bar ~180 C, header to the presses ~180 C,
  press outlets ~60 C (one per press, dimmed with the press when it is
  not installed in the selected case), supply header 20 to 25 C, oil
  cooler return <= 35 C (supply plus max. 10 K).
- Design target or estimate: raw water ~28 to 30 C (ground
  temperature), feed to the boilers 90 to 95 C, heat pump feed loop
  <= 95 C, condensate after the traps <= 100 C (atmospheric return),
  extruder returns <= 35 C (2 to 3 kW at 4 l/min), heat pump source in
  <= 60 C, return header up to ~60 C mixed, chiller loop to HX-1 ~18
  to 23 C (~2 K approach).
- To be set: heat pump source out, warm tank mixed temperature, chiller
  loop return.

The clicked details say where each figure comes from, including that
Newbilt's 180 C is saturation at 10 bar absolute (~184 C at 10 bar
gauge, to confirm). Legend explains the three tag styles.

Checked headless (scripts/pw_sc_check.py, now also tag overflow and tag
overlap with boxes, labels, symbols and each other): 20 tags, none

Deploy test site / deploy (push) Successful in 52s
Details 
- The feedwater loop between HP-1 and T-1 was drawn with class "hr",
  which had no stroke rule, so it was invisible. It now has its amber
  stroke, flow arrows both ways and a "feed loop" label.
- Number cells were white-space:nowrap, so the operating-case table ran

  phone page was 842 px wide. Numbers may wrap now (only the coverage
  percentages stay on one line), the side column and grid tracks may
  shrink, and units moved into the case table's row labels. Only the
  diagram scrolls sideways on a phone.

Checked headless (scripts/pw_sc_check.py, now also HTML card/table

Deploy test site / deploy (push) Successful in 44s
Details 
New page docs/steam-cooling.html (site /demos/steam-cooling/): the
utility plant as a clickable process diagram. Steam side: raw water,
softener and dosing, feed tank with heat-pump feedwater recovery, feed
pumps, a bank of two 500 kg/h boilers (third for N+1 as an option),
separator and metering, optional accumulator, blowdown, the 10 bar
header with a valved, metered branch and trap per press, drip legs and
condensate return. Cooling side: Newbilt's press outlets are open (max.
2 bar), so returns drain to a warm tank, pass the heat pump, an optional
dry cooler and a plate heat exchanger to a cold buffer tank, and VFD
pumps feed the 20 to 25 C header at ~10 bar to every press, the
extruders and the central hydraulic oil cooler; the chiller loop
(three 250 kW air-cooled modules at 40 C ambient, fourth as option) stays
closed and clean. Galvanics cooling (12 to 20 C) is a separate circuit.
Operating cases (launch, Duplex system 1, five presses, one module down)
show demand against installed capacity; design basis with sources,
equipment schedule, RFQ questions. Static SVG, no per-frame work.

Design basis at Newbilt's per-machine figures: steam 750 to 900 kg/h,
cooling 652.5 kW (625 presses, 15 extruders, 12.5 hydraulics), 305 to
540 l/min circulating. Also found: Newbilt's 53 l/min at ~60 C out is
~140 kW, above its 125 kW peak; listed as a re-quote question.

Re-based in the same commit:

grabowski 9b03e4de07 Plant overview: header bands follow the rounded box corners
Deploy test site / deploy (push) Successful in 44s
Details 
Every machine box has rounded corners (rx 4), but its header band was
a square rect inset by 1, painted over the box. At both top corners the
band's square corner covered the inside of the curved border, so the
border looked thin and squared off there, most visibly on a selected
box. The band is now a path with top corners of radius 3, concentric
with the box.

Measured on zoomed crops in headless Edge (light theme, selected
border): border thickness along the 45-degree diagonal against the
straight edge was 0.26 to 0.42 on the Traceability box, Classic C1 and
the VEX 50; now 0.9 to 1.13. Full UI check unchanged: all press states,

grabowski f776025b58 Plant overview: motion on canvas, no more lag
Deploy test site / deploy (push) Successful in 53s
Details 
The page spent most of each second laying out the SVG, not simulating:
the simulation itself costs ~26 ms per simulated hour. Profiled headless
on Edge (CDP metrics and a timeline trace with invalidation tracking):

- tokens asked the DOM for getPointAtLength right after writing a
  transform, which forced a layout of the whole SVG for every token,
  every frame (540 to 630 ms/s);
- ~55 CSS stroke-dashoffset animations repainted the drawing all the
  time;
- the press platens were SVG rects moved every frame, and any geometry
  write re-lays-out the whole SVG with its 275 text labels.

Now the SVG holds only the machines and labels. Pipes, flow dashes and
the conveyor are drawn on a canvas under it; tokens, records, platens,
cakes, the extruder screw and plating bubbles on a canvas over it, both
with the SVG's own viewBox transform, so pan and zoom need nothing extra.
Routes are measured polylines (ptAt) instead of DOM path queries, and
the 5 Hz tag, lamp and KPI writes only touch the DOM when the value
changes.

Headless Edge, 1600 x 900, before -> after:
  1x     26 -> 60 fps, layout 842 -> 26 ms/s, long tasks 19 -> 0
  60x    19 -> 59 fps, layout 858 -> 29 ms/s
  600x   18 -> 60 fps, layout 855 -> 30 ms/s
  3600x  33 -> 60 fps, layout 726 -> 29 ms/s

Behaviour unchanged: all press states seen at 3600x, 47 stations open
their detail, steam dip holds and recovers, lot and repress log, no text
overflow at 1600 x 900 and 1258 x 800, canvas and SVG agree within
0.2 px at fit, zoomed, 1258 x 800 and phone size, both themes, no

User, October 2026: take the BOI duty-free import and VAT exemption into
consideration.

- boi.md: import VAT goes with the BOI duty exemption (Revenue Department
  answer on the BOI OSOS FAQ, checked October 2026); what it is worth:
  ~2.75M USD of imported machinery at the start fleet (block midpoints)
  would otherwise carry ~5 % duty (Thai MFN averages 4.1 % on HS 8477,
  0 to 10 % across HS 84; estimate until the HS codes are set), ~0.14M
  USD, and 7 % import VAT, ~0.2M paid at the border and recovered later
  as input tax, mostly as a refund claim since exports are zero-rated.
- total-investment.md: the blocks are vendor prices without duty or
  import VAT, so the headline already assumes promotion.
- Fleet calculator: BOI promoted / not promoted switch and export share.
  Not promoted adds the machinery duty to capex and depreciation, shows the
  import VAT as cash at the border, and charges duty on imported PVC
  compound; promoted exempts both, with no compound duty on exported
  records and 90 % off for domestic sales (sections 36(1) and 30). A note
  under the KPIs shows what promotion saves either way. Defaults: payback

- New card "Machine park and stamper production": one live SVG that
  follows every input. Top: the stamper line, lathe, Pheenix PASU, PPPU,
  PDPU (2 cells), PMPB, Sibert VSF, VSP, VSC, each with its count, flow a
  day and how busy it is. Middle: the press hall, each Duplex cell drawn as

  behind, trimmer in front) and each Classic with its built-in extruder,
  wrapping into rows and scaling down for big fleets; compound in on the
  left, stamper rack in and finishing out on the right. Bottom: central
  hydraulics, boiler, cooling, air and electrical piped up into the hall,
  amber where they exceed the plant as planned today.
- Stamper production is now counted per station from the cycle times in
  galvanics.md (silvering, pre-plate four at a time, father, mother,
  stamper plus handling per PDPU cell, PMPB, Sibert steps; usable share of
  the hours 80 %, estimate) instead of a flat 20 to 32 parts per PDPU.

  planning tank, 9 m x 4 m (254 m3 gross, ~200 m3 usable), new params
  fw_dia, fw_h, fw_x, fw_y, at the front by the access road, outside the
  production yard, on a ring foundation, with a pump house (duty electric,
  standby diesel, jockey); the yard process water tank is now the 5 x 3 m
  raw water tank of the phase 1 RFQ.

Docs: site-candidates (cell, raw water, fire water bullet),
facility-security (the Payap model draws the tank; 6 m racking and twice
the floor area make ~200 m3 a floor there).

grabowski 7da64088ce Duplex cell layout: one operator, presses turned towards him 
User sketch, October 2026 (filed as docs/equipment/
duplex-cell-layout-sketch.png; arrangement only, the user notes it is not
to scale): operator in the middle, the two presses either side turned 45
degrees towards him, EX 50 and EX 35 side by side behind him, one trimmer
per cell in front on the left.

Sized from the Newbilt site requirements p. 10 (press ~0.9 m2, extruder
~0.5 m2, hydraulic aggregate ~1.0 m2, walk-around space, >= 60 cm to
walls, room height >= 2.5 m): cell ~5 x 3 m, 0.6 to 0.8 m between
machines; EX 35 and trimmer footprints are estimates. The layout drawing
the site requirements refer to on p. 11 is missing from our copy: ask
for it with the re-quote. README layout line for the sketch.

grabowski 83840d45dc Payap model v4: colour store, silos, two-storey finishing and print block 
User, October 2026: ground-floor colour store plus outdoor silos; a
two-storey block at the east end with packaging below and printing plus
print and packaging stock above; in-house printing not decided, so the
print room is reserved only.

Model (rebuilt live in FreeCAD 26.3 after checking a copy of the saved
file for user edits; parametric check plot 150->160 m and upper floor
3.8->4.2 m passed):
- factory 128 x 25 m, plot 150 m (14.1 rai), corridor 98 m, fire wall
  at 106 m, new params crane_x (runway end = press hall end, 92 m) and
  mezz_z (+3.8 m);
- galvanics open to stamper prep (wall kept only on the material area
  and electrical side);
- colour store 10 m bay (~180 m2): two racking rows, ~100 pallet
  positions on 4 levels (estimate), weighing and mixing, vacuum
  conveying station; indoor silos replaced by regrind bins;
- 4 outdoor PVC silos (2 black, 2 standard colours, ~50 m3 each,
  estimate), big-bag filling station, buried conveying lines;
- finishing and print block 14 x 25 m: ground floor trim, optical
  inspection, QC, packaging (tables, shrink wrap, pallet wrapper), stair
  (Arch Stairs) and goods lift; upper floor print room (reserved), print
  stock, packaging materials.

grabowski d9f3a4b88e Compound storage for tens of colours; stamper prep open to galvanics 
User, October 2026: special designs will need tens of colours, so the
compound store needs far more space, with maybe a few silos for black and
the standard colours; and the wall between stamper prep and galvanics is
to go.

- pressing-line: "Compound storage" bullet (colour store with pallet
  racking, ~100 positions in the Payap model, estimate; outdoor silos
  proposed; compound stays on the ground floor, ~160 to 270 t a year at
  the mature fleet; sacks vs big bags decides the silo filling).
- galvanics: stamper prep open to galvanics, one clean zone.

grabowski 0700c14b5c Payap model: two-storey office building with canteen, changing and showers 
User, October 2026: the office building also houses several showers, a
changing room, toilets and a canteen; the office area itself about
150 m2; the building can be multi-storey.

Model (office rebuilt live in FreeCAD 26.3; factory and site untouched):
- 32 x 15 m on two storeys (off_storey 3.6 m), ~960 m2 of floor, Arch
  Stairs plus a lift, first floor slab with the stair and lift void;
- ground floor: reception and lobby (entrance and link door), canteen
  ~40 seats with kitchen and servery, changing rooms women and men with
  4 showers each and lockers, toilets, mastering and cutting (acoustic
  lining), listening room, archive;
- first floor: offices 147 m2 (16 desks), training room (Payap
  programmes), meeting room, IT and server, toilets, pantry, flexible
  room;
- factory staff entry relabelled "PPE, WC" (changing is in the office).

grabowski 4263fbbd9b Payap model v2: bigger factory, shared plant room, separate water treatment 
User, October 2026: the factory is too small and needs room to grow
(possibly ten more Classics), one shared hydraulic and air supply, water
treatment perhaps in a separate building connected to the galvanics lab,
and a fully equipped workshop (maintenance tools, 3D printers, maybe a
lathe and a small CNC mill).

Model (rebuilt live in FreeCAD 26.3, BIM objects, Params-driven,
parametric check plot 135->145 m and factory 112->120 m passed):
- plot 135 m (11.4 rai) with a reserve; factory 112 x 25 m, 16 bays,
  82 m visitor corridor, fire wall at 90 m;
- press hall ~870 m2: two Duplex systems (EX 50 + EX 35), the Classic,
  ten future Classic positions in two rows on a service trench;
- central hydraulics and compressed-air plant room (~62 m2);
- water treatment building 12 x 10 m behind galvanics: buried duct
  (gravity from the +1.2 m floor), covered crossing 6 m clear;
- workshop ~200 m2 with benches, tool cabinets, 3D printers, lathe,
  small CNC mill, drill, saw, welding bay, press, washer, measuring table.

Docs: galvanics (water treatment building, proposed), crane doc (workshop
fit-out; lathe and CNC mill not yet priced; corridor now 82 m),

grabowski 9e0c5d4045 Fleet: one shared hydraulic and air supply; room for ten more Classics 
User, October 2026: the presses run from one shared hydraulic supply
and one compressed-air supply, and the plant may add up to ten more
Newbilt Classics at some point.

- pressing-line: fleet table and intro (shared central supply), new
  bullets on the shared supply and the expansion option, re-quote point
  (central supply for the whole fleet, extendable, can the Classic run
  from it), Hydraulics bullet now the plan.
- scale: "Expansion (option)" capacity row, ~4.7 to 5.8M records/yr on
  the same basis, explicitly outside revenue model and investment;
  utilities note: fifteen presses would need ~2.3 to 2.7 t/h steam and
  up to ~1.9 MW cooling, a utility phase of its own.

grabowski f2bb7f3d85 Payap scenario: parametric BIM model of the whole plant on a square plot 
A separate FreeCAD 26.3 model (the Mueang Chi model is untouched) sites
the plant on a 110 m square placeholder plot of Payap land, built from
BIM objects (Arch Site, Buildings and Levels, walls, slabs, columns,
beams, a ramp, Spaces with computed areas, Equipment). Every object sits
on an expression-driven base, so the Params sheet drives plot, setbacks,
floor level, building sizes, fire wall line and office gap (checked:
plot 110 to 120 m and factory 84 to 90 m, everything followed).

- Factory 84 x 25 m, production only, in process order along a 54 m
  glazed corridor; press hall 465 m2 with the October fleet (two Duplex
  systems, each EX 50 + EX 35, and the Classic); crane to the fire wall;
  machine door and 12 m ramp at the north-west corner.
- Office building 24 x 15 m, 12 m away on its own slab with a covered
  link: reception, offices, meeting/training, mastering and cutting,
  listening, IT, archive. Resolves the crane-zone conflict of the old
  sketch.
- Utility yard behind the press hall (boiler and chiller flagged for
  re-sizing), gate, truck apron, car park, service road.
- site-candidates: new section and plot-fit note; crane doc: conflict
  resolved, 54 m corridor; README bullet and layout lines; the old
  sketch is labelled as Mueang Chi with the earlier fleet.

grabowski 3a758fcffb Fleet: each Duplex has an EX 50 main and an EX 35 colour extruder 
Correction from the user: the two Duplex systems are not in the
two-extruder configuration. Each runs two HRP 12 presses from an EX 50
main extruder with an EX 35 auxiliary extruder beside it for a second
colour; the Classic stays. Fleet still five presses. Updated in
pressing-line (table, phasing, re-quote: EX 50 vs the VEX 50 of the 2024
quote, and whether one EX 50 keeps both presses at full rate), scale,
total investment (wording; estimates unchanged), roadmap item 4, README.
