# Changelog v0.5.36 - 2026-06-20

### Fixed
- **Router priority ordering now respects explicit priority over circuit state.** Previously, routing candidates were ordered strictly by circuit state (`CLOSED` candidates always before `HALF_OPEN`), then by priority and health score. This meant a high-priority model sitting in `HALF_OPEN` recovery could be skipped in favor of a lower-priority `CLOSED` model — defeating the whole point of explicit priority levels. The comparator now sorts by **explicit priority first**, then by circuit state (`CLOSED` before `HALF_OPEN`), then by health score. Higher-priority models are never again jumped over just because they are mid-recovery.

### Changed
- **Probe loop hardening.** `scheduleProbeLoop()` now clears a stale `probeWatchdog` timer alongside the main probe timer, tracks `lastProbeAt` timestamps after every successful cycle, and wraps the scheduling body in a `try/catch` so a single failed probe cycle can no longer destabilize the background routing daemon. Results in more reliable health-check cadences across the CLI, web, and Tauri surfaces (shared core).

### Added
- **Public re-exports of the provider-key-test helpers** from `key-handler.js` (`buildProviderModelsUrl`, `parseProviderModelIds`, `listProviderTestModels`, `classifyProviderTestOutcome`, `buildProviderTestDetail`). Completes the shared-module refactor introduced in #121 (provider key testing moved to `src/core/provider-key-tester.js`) so the TUI key-handler exposes the same surface other modules already consume.

### Docs
- **Credited @MoriDanWork** in the README contributors table and the AGENTS.md contributor list for PR #121 (move provider key testing to a shared module).
