This commit overhauls the dashboard styling to achieve a 'retro terminal' look matching the Gruvbox color palette. Changes include switching the global font to JetBrains Mono/Fira Code, removing rounded corners on all major elements (cards, buttons, inputs, modals, badges), and replacing modern soft shadows with sharp, hard-offset block shadows.
This commit adds a proper flexbox layout to the '.card-actions' CSS class. Previously, action buttons (like Export and Refresh on the Analytics page) were bunching up because they lacked a flex container with appropriate gap and wrapping rules. It also updates the '.card-header' to wrap gracefully on smaller screens.
This commit corrects the CSS for the login form's floating labels. Previously, the label floated too high and had a solid background that contrasted poorly with the input box. The label now floats exactly on the border line and uses a linear-gradient to seamlessly blend the card background into the input background, fixing the 'misframed' appearance.
This commit updates the frontend API client to intercept authentication errors (like a stale session after a server restart) and immediately clear the local storage and show the login screen. It also adds an onsubmit handler to the login form in index.html to prevent the browser from defaulting to a GET request that puts credentials in the URL if JavaScript fails to initialize or encounters an error.
Add complete multi-user support with role-based access control:
Backend:
- Add users CRUD endpoints (GET/POST/PUT/DELETE /api/users) with admin-only guards
- Add display_name column to users table with ALTER TABLE migration
- Fix auth to use session-based user identity (not hardcoded 'admin')
- Add POST /api/auth/logout to revoke server-side sessions
- Add require_admin() and extract_session() helpers for clean RBAC
- Guard all mutating endpoints (clients, providers, models, settings, backup)
Frontend:
- Add Users management page with create/edit/reset-password/delete modals
- Add role gating: hide edit/delete buttons for viewers on clients, providers, models
- Settings page hides auth tokens and admin actions for viewers
- Logout now revokes server session before clearing localStorage
- Sidebar shows real display_name and formatted role (Administrator/Viewer)
- Fix sidebar header: single logo with onerror fallback, renamed to 'LLM Proxy'
- Add badge and btn-action CSS classes for role pills and action buttons
- Bump cache-bust to v=7
- All usage endpoints now accept ?period=today|24h|7d|30d|all|custom
with optional &from=ISO&to=ISO for custom ranges
- Time-series chart adapts granularity: hourly for today/24h, daily for
7d/30d/all
- Analytics and Costs pages have period selector buttons with custom
date-range picker
- Pricing table on Costs page now only shows models that have actually
been used (GET /models?used_only=true)
- Cache-bust version bumped to v=6
Track cache_read_tokens and cache_write_tokens end-to-end: parse from
provider responses (OpenAI, DeepSeek, Grok, Gemini), persist to SQLite,
apply cache-aware pricing from the model registry, and surface in API
responses and the dashboard.
- Add cache fields to ProviderResponse, StreamUsage, RequestLog structs
- Parse cached_tokens (OpenAI/Grok), prompt_cache_hit/miss (DeepSeek),
cachedContentTokenCount (Gemini) from provider responses
- Send stream_options.include_usage for streaming; capture real usage
from final SSE chunk in AggregatingStream
- ALTER TABLE migration for cache_read_tokens/cache_write_tokens columns
- Cache-aware cost formula using registry cache_read/cache_write rates
- Update Provider trait calculate_cost signature across all providers
- Add cache_read_tokens/cache_write_tokens to Usage API response
- Dashboard: cache hit rate card, cache columns in pricing and usage
tables, cache token aggregation in SQL queries
- Remove API debug panel and verbose console logging from api.js
- Bump static asset cache-bust to v5
API endpoints return valid data via curl but browser JS shows 'Failed to load'.
Added verbose logging and a fixed-position debug panel to api.js that displays
the exact error type (JSON parse, API error, or network exception) on-page.
Bumped cache-bust to ?v=4.
- Added 'provider_configs' and 'model_configs' tables to database.
- Refactored ProviderManager to support thread-safe dynamic updates and database overrides.
- Implemented 'Models' tab in dashboard to manage model visibility, mapping, and pricing.
- Added provider configuration modal to 'Providers' tab.
- Integrated database overrides into chat completion logic (enabled state, mapping, and cost).

- Improved sidebar with tooltips and persistent collapsed state.
- Fixed chart memory leaks by properly destroying instances on page change.

- Implemented unified ApiClient for consistent frontend data fetching.
- Refactored dashboard structure and styles for a modern SaaS aesthetic.
- Fixed Axum 0.8+ routing and parameter syntax issues.
- Implemented real client creation/deletion and provider health monitoring.
