Replaces cronus's U0-U4 catalog at /tools/procedures with a
persistence-backed builder shell on top of B0's API surface
(/api/builder/scenarios/*, t-paliad-340).
PRD §7.1 B1 acceptance shipped:
- Page header: scenario picker, name action, Akte picker stub,
Stichtag input, search input, save status indicator.
- Entry-mode radio (cold-open active; event-triggered + akte
rendered disabled for B3/B4 layout stability).
- Empty canvas with "Neues Szenario starten" CTA and a 5-most-recent
list rendered when the user has saved scenarios.
- Side panel "Meine Szenarien" with the Aktiv bucket; clicking an
item loads the scenario into the canvas.
- Add-proceeding inline picker (Forum chip row → Verfahren chip row
→ Hinzufügen). UPC v1; other forums chipped but disabled.
- First proceeding triplet renders end-to-end via
verfahrensablauf-core.calculateDeadlines + renderColumnsBody (the
existing 3-column proaktiv|court|reaktiv body, read-only in B1).
- Auto-save with 500ms debounce on name + stichtag patches; save
status flips idle → saving → saved/error in the page header.
New client modules under frontend/src/client/:
- builder.ts — orchestrator (URL state, fetch, auto-save loop,
canvas render, scenario-list re-paint).
- builder-picker.ts — inline Forum/Verfahren popover for the
add-proceeding affordance.
- builder-triplet.ts — single-triplet header + body wrapper.
procedures.tsx rewritten as the shell scaffolding (sidebar, page
header, mode radio, two-column body); procedures.ts now boots the
builder instead of toggling the 4-tab catalog.
Legacy U0-U4 modules (verfahrensablauf.ts, verfahrensablauf-state.ts,
VerfahrensablaufBody.tsx, procedures' tab toggle in client/procedures.ts,
fristenrechner-* mounts) are no longer reachable from /tools/procedures
but kept in the tree for the B6 cleanup sweep per PRD §7.4.
i18n.ts grew 60 keys × 2 langs under builder.*. global.css grew a
self-contained .builder-* block at the file tail.
bun run build, go vet ./..., and go test ./... all green.
