…opy link

Card.of resolves every kind with map gets only; Cards caches them and
drops by the object ids an event touches (reverse index, no walks).
Trail keeps back/forward in the Ui scratch; ref-go/ref-back/ref-fwd
navigate through the existing select/bot/room/project/file handlers;
ref-copy/ref-copy-web and Copy link in the thread, project, bot and
file menus.

Hub.prompt is Hub.prompt.base plus the optional language line, so the test
checks the off setting byte for byte against the base as it is now and
does not break when other prompt text changes.

…anguage follows a change

The window's Language chips are right-aligned to the card like Theme's, the
agent row is an On/Off pair like the notification rows, and both rows have
a note. Changing this device's language while "Agents reply in my language"
is on moves agent.lang to the new language.

Language setting on every client, and agents can reply in your language

Short ages say 前 (3分前, not a bare duration), the delete question is
polite, files changed is a label, the author label is 自分, a routine whose
time has come is 実行時刻です, and the agent-language row says which
language. docs/i18n/glossary-ja.md holds the terms and the spacing and
punctuation rules. English is unchanged.

…ords

Japanese wording from an independent review, and the glossary

A small Python service (order/fabsrv) the hub talks to: /v1/estimate prices
bare parts from their features, /v1/quotes takes a manifest and files,
measures them in a sandboxed process (gerbers, drills, BOM, positions, STEP,
DXF), sources components, adds shipping, duties and the fee, and serves a
quote page whose Pay opens Stripe Checkout. Rate limits per address and
install, read tokens kept hashed. The fab's price models are a private pack
loaded from FAB_VENDOR.

core/order.bend: the intent (.backplane/intent.md) and fab files (*.fab.json)
read into a card with the order server's price for the bare parts; every
agent is told to keep both, and a buy thread (Buy it: setting buy.<thread>)
gets its own instructions and the order_quote/order_status tools. The hub
(server/orderio.bend) asks the person with every file listed before it
uploads, waits for the quote, posts it with its Pay link, and follows the
order until it is delivered (records in <home>/orders, resumed at start).
Agents also get the free pcbparts MCP for parts by part number.

Every client shows the intent's goal above a project thread with Edit
(the intent into the composer; /intent sends it back) and Buy it with its
price; the window and the web open the whole intent, the phones show it
as a row above the composer (bundled bridge only, no native code).
Settings has Price estimates on all four. Laws order_buy_*, intent_edit_*,
order_tools_buy_only.

…the review, tappable questions

The quote's board price takes the via tier its smallest plated hole needs
(a 0.2 mm via costs more than a 0.3 mm one); fab.json may say min_drill_mm
for the estimate. The buy agent reviews against the fab's real track, gap
and via limits, and asks its questions with AskUserQuestion. The upload's
approval card asks "Send these files for a quote?", and the intent file
is written readable like any project file.

The card counts the project's KiCad boards when no part has a fab file
(and checks the order server is there); the buy agent writes the missing
fab files first. Laws order_buy_board_only, order_buy_board_unreachable.
