 ### Recent Fixes
 
+- **2026-04-28**: **#1115** CCS now exposes upstream CLIProxy session affinity as a first-class local managed setting. Users can inspect and toggle local `session-affinity` plus TTL from `ccs cliproxy routing affinity`, from the `/cliproxy` dashboard routing card, and through the local dashboard API. The generated local CLIProxy config now persists `routing.session-affinity` and `routing.session-affinity-ttl`, help/copy explains that CLIProxy prefers explicit session or thread identifiers before falling back to prompt-history hashing, and remote session-affinity management stays explicitly unsupported until upstream management APIs expose more than `routing.strategy`.
 - **2026-04-24**: **#1065** Local CLIProxy Plus is available again as an explicit opt-in backend through the community-maintained `kaitranntt/CLIProxyAPIPlus` fork. CCS keeps `original` as the default backend, no longer downgrades saved `backend: plus` configs to `original`, updates Plus release lookups to the maintained fork, and documents Plus as a targeted path for plus-only providers.
 - **2026-04-21**: CLIProxy quota failover now quarantines exhausted Claude and Antigravity accounts out of live rotation when a healthy fallback exists. CCS persists those quota-triggered pauses across launches, automatically resumes them after the configured cooldown window, and deliberately avoids auto-pausing the last available account so single-account setups still degrade gracefully instead of hard-locking themselves.
 - **2026-04-20**: **#1051** Browser automation now defaults safe-off for new installs and upgrades that do not already carry explicit browser settings. CCS changes both Claude Browser Attach and Codex Browser Tools to start with `enabled: false` and `policy: manual`, normalizes missing browser policies on upgrade back to `manual`, preserves explicit existing enablement, and updates status/help/docs so browser tooling is never implied to auto-expose unless users opt in.
