The gage lab assigns real WJRP asset numbers, so identity splits: the
internal itemcode stays auto-minted and a new optional unique
gagelabtag (migration 0003) carries the lab's number - settable on
create/edit, searchable, and resolved by the kiosk for scans and bare
keypad digits against the numeric tail of either identifier
(unique-match only). The print-files table becomes stacked revision
cards - filename with rev/current badges, one meta line, delete pinned
right - ending the horizontal scroll in that column.
The milestone workbook becomes a from-scratch guide with the actual
code inline for every core stage: models, the real migration baseline,
read routes and the list page, mutations and minting, the badge
resolver (final mode-aware form), the single-commit ledger invariant,
RBAC gating, both kiosk endpoints with the wedge-input and focus-guard
mechanics, the 1x0.5in label CSS, and the reconcile query. Field
extensions stay summarized against their tags. New section: how to
contribute a plugin through GitHub (branch, stage commits, the three
CI gates, PR expectations, review checklist, and how publication
folds PRs into release commits).
The resolver only read the self-hosted directory table, which is empty
at sites running the external HR directory - every kiosk badge fell to
the deny policy. It now branches on employee_directory_mode like the
usb plugin: selfhosted looks up DirectoryEmployee by SSO; external
queries the HR directory via employee_connection, resolving PayNo
badges by their real PayNo column and recovering the employee's SSO.
Browsing the catalog (item list, detail, file listings) now requires
authentication plus the view permission, and the /printedparts pages
and the label print page require login. Still deliberately open: the
kiosk endpoints per the decision record, the image serve and file
download (img tags and anchor downloads cannot carry a JWT), and the
reports (product-wide jwt-optional convention). Grant
printedparts.view to the roles that should see the catalog.
The tap-anywhere wedge refocus stole focus from the manual-entry field
the moment it was tapped - the handler now only reclaims focus from
dead space, never from a real control. Manual entry works without a
physical keyboard: badge entry uses the TouchKeypad (an SSO is
digits), and item lookup accepts bare digits resolved by row id - the
digits in a minted code are the id, which also keeps labels printed
under an older prefix scannable after the prefix changes.
printeditemfiles lands as the plugin's first incremental migration
(0002 on the plugin chain - the ADR-008 payoff). Revisions are
append-only per item: upload assigns the next number, records the
uploader from the JWT, enforces an extension allowlist and a 100 MB
cap; download serves the original filename; a permission-gated delete
covers wrong-file mistakes. The detail page gains the revision table
with a current badge. Unique storedfilename is sized 191 so the index
fits MySQL's 767-byte prefix - the per-plugin chain does not apply the
core env's ROW_FORMAT hook.
Alert recipients gain roles: Role joins the 0.13.0 surface, a role
picker on the settings page, and every active member of the selected
roles is folded into the deduped recipient list.
Retire button with confirmation on the detail page (item leaves the
storefront and the kiosk rejects its code; ledger history and label
survive), Restore on retired items, and an Include-retired list toggle
with a badge. Restore is its own permission-gated POST - the generic
update still cannot flip isactive. New codes mint as WJRP0042 style
without the dash; existing codes are immutable bin labels and keep
their form.
Contract 0.13.0 puts the User model on the plugin surface. The
settings page gains a checkbox picker over the user list; selected
users receive low-stock alerts at their account email, merged and
deduped with the free-text address list, inactive accounts skipped,
site alert_recipients still the fallback when both are empty.
PrintedPartsSettings edits the four plugin settings (code prefix,
default threshold, kiosk badge policy, alert recipients) through the
core settings API; the route rides the plugin's router file and the
settings shell nests it into the rail; get_settings_cards contributes
the catalog card while the plugin is enabled.
Contract 0.12.0: send_email/send_alert join the plugin surface (the
mailer was core-only), PLUGIN-HOOKS and status docs updated, manifest
pins the new floor. The alert fires inside _ledger_write only when a
decrement CROSSES the item's threshold - one alert per depletion,
rearmed by restocking above - and is best-effort after the commit so
mail trouble can never fail a take. Recipients come from
printedparts_alert_email, falling back to the site alert_recipients.
on_enable re-seeds settings idempotently so existing installs pick up
new keys. Crossing/rearm semantics proven by test.
The lab is now a build-along mirroring what actually happened: ten
stages, each with the goal, the divergences, a see-it-work check, and
the errors genuinely hit while building (empty Migration error from a
broken model import, the migration-guard KeyError, the missing Lucide
icon, nested-app-context test writes, Decimal sums, and the authz
sweep catching the deliberately open kiosk take). That last one gets
its explicit EXEMPT_ENDPOINTS entry with a pointer to the decision
record - the net stays, the exception is reviewable. Full suite: 993
backend tests, 49 vitest, frontend build, naming hook, all green.
State that this is a bundled plugin whose frontend and three small core
edits land in this repo, list the three deliberate divergences from the
scaffold before the learner hits them, suggest a per-milestone solution
branch for instructors, and point out the earliest visible win (wire
the bare list page as soon as the GET endpoint works).
The kiosk take endpoint is the product's first unauthenticated
mutation; spell out the acceptance criteria (decrement-only, badge
attributed, bounded, physically rate-limited) so future open-write
endpoints meet the same bar. The dashboard-widget milestone is marked
optional: get_dashboard_widgets predates the ADR-010 data-only
renderers and needs a core component to render.
Design for a 3D-printed-parts storefront: item catalog with images and
quantity on hand, a transaction ledger attributing every take/restock/
adjust to a badge-scanned employee, an unauthenticated touch kiosk
(scan bin barcode, scan badge, keypad quantity), 1x0.5in CODE128 bin
labels, and stock/consumption/by-person reports.
The lab guide walks a developer through building it in seven
checkpointed milestones, reusing the USB badge contract, the
measuringtools migration baseline, the models-image upload trio, and
the open kiosk-endpoint precedents.
