Customer-side parity: sk-or- is recognised as OpenRouter, the provider picker falls back on an unknown prefix, and own-key credit billing for api goes through STONE.
Provider picker and counter on every model list (pure LDC UI): an "All providers" picker per list (chat picker, model preferences, Providers dashboard, model report) plus a "Showing N" counter based on the current selection (provider + status filter + curation + search). The chat list respects the customer's curation.
Customer curation unified behind a single endpoint: all curation (provider and model — hide, favourite, ordering) is read and written via GET/PUT /api/me/curation, the same account-scoped store the web uses. Falls back gracefully to /api/me/model-preferences if curation does not answer. touch still uses model-preferences/touch.
Layer 3 — customer curation at provider level: the customer can hide or show whole providers (eye button) in their own lists; hiding a provider removes its models from the chat model picker. Built against the shared account-scoped /api/me/curation with a graceful 404 fallback. Model-level curation is unchanged via /api/me/model-preferences.
A shared model filter (Active · All · Disabled) on every model list: one global choice covering the Providers dashboard, provider detail, the chat model picker and model preferences (default "Show active only"). "Active" means assigned to the customer, "Disabled" means unassigned or deprecated. This is purely a display filter.
The model list in the Providers section is now derived from assignments: only models the system administrator has assigned to the customer (per provider) are shown; providers with no assigned models are hidden; no assignments means an empty list. The provider detail page shows assigned models only.
Fixed downward sync of LLM providers and models from lexico.no: models a system administrator removes or disables now also disappear from LDC's local cache; the Providers dashboard and detail page refresh live without a manual sync; customer-specific access (/api/me/allowed-models) syncs down independently of the global catalogue version (roughly every 30s, and on focus).
Currency selection now also applies to model prices (IN/OUT per 1K tokens) in the provider detail view — shown in the selected currency with live rates.
KaTeX font (CSP fix), self-healing lexico-ldc: protocol handler, and live exchange rates on the dashboard (NOK/SEK/DKK/EUR match lexico.no).
