 ### Recent Fixes
 
+- **2026-04-14**: **#991** CCS now auto-routes Claude-target settings profiles that use OpenAI-compatible endpoints through a local Anthropic-compatible proxy instead of sending raw Anthropic `/v1/messages` traffic directly to chat-completions backends. The new `ccs proxy` command supports `start`, `status`, `activate`, and `stop`, the runtime exposes `/health` and `/v1/models`, the shared SSE parser now handles multi-line `data:` payloads, and the feature ships with dedicated unit, integration, and e2e coverage.
 - **2026-04-10**: **#765** `/providers` now includes a first-class Hugging Face preset for API Profiles. CCS exposes Hugging Face Inference Providers through the existing OpenAI-compatible profile flow with the official router endpoint `https://router.huggingface.co/v1`, a short `hf` default profile name, and `hf` preset alias support for both the dashboard chooser and `ccs api create --preset hf`.
 - **2026-04-10**: **#944** Image Analysis auth readiness no longer collapses to native Read when merged runtime-status dependency overrides include a missing initializer value. CCS now preserves default dependency functions when override entries are `undefined`, still reads token-backed auth status directly in the local readiness path, and includes regression coverage for the missing-initializer case that previously surfaced as `deps.initializeAccounts is not a function`.
 - **2026-04-10**: **#945** CCS now normalizes Gemini CLI and Antigravity tier signals around an explicit `free / pro / ultra / unknown` model, preserves raw tier ids such as `g1-pro-tier`, enriches Gemini quota responses with provider entitlement evidence, classifies `MODEL_CAPACITY_EXHAUSTED` separately from auth/entitlement failures, fixes the Antigravity CLI quota table so live quota-derived tiers no longer collapse back to stale `unknown`, adds Gemini tier ids to CLI quota output, extends Gemini Flash Lite grouping to cover `gemini-3.1-flash-lite-preview`, and allows Gemini account surfaces to render the same tier badge semantics as Antigravity.
