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.
User, October 2026: we want unified Engelbert Strauss work clothes.
- worker-safety.md: decision recorded; everyone, office included, in the
same Strauss workwear with the company logo, process PPE on top. Kit at
Strauss catalogue prices checked October 2026 (incl. 19 % German VAT,
which drops out on export): production 3 trousers e.s.motion 2020, 3
polo shirts, 2 T-shirts, a sweatshirt, S1 safety shoes e.s. Vasegus II
low, ~293 EUR before VAT, ~338 with embroidered logos (embroidery price
an estimate); office 4 polos and a softshell jacket, ~127 EUR. Ordering:
Strauss ships outside Germany where customs law allows, shipping quoted
with the order, prepayment, duty and taxes charged to the recipient;
Thai duty on work trousers 13.8 %, BOI does not cover clothing. About
9k USD (~0.3M THB) a year at the start fleet. Check lighter lines for
the press hall heat with samples.
- revenue-model.md: workwear noted on top of the x1.3.
- Fleet calculator: workwear line under labour (production and office
kits a year, shipping and Thai duty), six new assumptions; 8,573 USD a
year at the defaults.
User, October 2026: option to enter base salaries; the company should
provide proper extra health care with check-ups for all staff.
- worker-safety.md: new "Health care for all staff" policy (decided
October 2026): group health insurance (inpatient and outpatient) and a
yearly check-up for everyone, office included, on top of social
security; the occupational checks Thai law requires for risk-factor
work (Ministerial Regulation B.E. 2547: within 30 days, then yearly, by
an occupational physician, records kept 2 years after the job ends) for
the press floor, galvanics and maintenance; planning costs with sources
checked October 2026 (group insurance ~8,000 to 18,006 THB a head a
year, plan ~15,000; Rajavej Chiang Mai check-ups 1,290 to 5,990 THB,
plan ~2,500 plus ~1,500 risk-factor tests, estimates); social security
5 % up to the 17,500 THB ceiling since 1 January 2026.
- revenue-model.md: cutting engineer 50,000 THB is base salary; health
care on top of the x1.3 (~0.35M THB a year at the start fleet); what the
x1.3 is made of.
- Fleet calculator: base salaries per role (the revenue model loaded
rates / 1.3; cutting engineer 50,000), employer social security 5 %
capped at 17,500, 25 % overtime, bonus and PPE, health insurance and
check-ups for all staff incl. 4 office staff (scale.md 3 to 5), risk-
factor tests for the press floor, galvanics and maintenance; all as
editable assumptions; people table gains office and all-staff rows.
Defaults: labour 5.25M THB (was 4.67M loaded), direct cost 1.90 USD a
record, EBITDA 2.19M USD.
New docs/crane-workshop-tours.md: a 5 t single-girder EOT crane over the
whole production compartment (stops at the warehouse fire wall), a
machine door and crane-served workshop/machine bay at the ramp end, and
a glazed ground-level visitor corridor along the car-park elevation with
stations in process order, its own air and acoustic glazing so tours
need no PPE. Covers what each changes in the shell (crane-ready frame,
hook height under the 7.0 m eave, no full-height cross walls in the
crane zone, room lids and crane hatches), safety, costs and open
decisions.
Propagated: construction RFQ (crane-ready frame, new section 1c, machine
door, accessible 1:12 entrance now required), scale zone table (+210 to
280 m2, total ~1,400 to 2,000 m2), facility security, worker safety,
roadmap items 9 and 15, total investment added-scope table, README.
