## Summary Fixes #345 Adds UI controls for the existing `initialMinutes` and `maxMinutes` exponential backoff settings in the Cooldown Manager, exposing them on the Configuration page. The new "Cooldown Settings" card follows the same pattern as the existing "Failover Settings" Disclosure card. ### Changes **Backend** (`packages/backend/src/routes/management/config.ts`): - Added `GET /v0/management/config/cooldown` — returns current cooldown policy (`initialMinutes`, `maxMinutes`) - Added `PATCH /v0/management/config/cooldown` — merges updates and persists via `ConfigService.setSetting` **Frontend API** (`packages/frontend/src/lib/api.ts`): - Added `getCooldownPolicy()` — fetches cooldown policy from backend - Added `patchCooldownPolicy()` — patches cooldown policy fields **Frontend UI** (`packages/frontend/src/pages/Config.tsx`): - Added "Cooldown Settings" Disclosure card with: - Description of the exponential backoff formula: `C(n) = min(C_max, C₀ × 2ⁿ)` - Numeric input for **Initial Cooldown** (`initialMinutes`, default 2) - Numeric input for **Maximum Cooldown** (`maxMinutes`, default 300) - Save button that persists changes via the API Co-authored-by: Pi Bot <pi-bot@plexus.dev>
