Remote debugging without shell access: a tracing layer tees every event at DEBUG-and-up — independent of the RUST_LOG filter gating stderr/host.log, so console-side debugging never needs a restart — into a bounded in-memory ring (log_capture.rs, 4096 newest entries, OnceLock singleton like config()), installed at both init sites (stderr path in main, the Windows service file path). The mgmt API serves it cursor-paged at GET /api/v1/logs?after=&limit= — bearer-only and deliberately NOT on the mTLS cert allowlist (log lines can name client identities and host paths). The web console grows a Logs page (follow/pause · min-level filter · text search · eviction-gap badge); polling self-paces: a non-empty page advances the after-cursor (new query key → immediate refetch, drains backlogs), an empty page idles at the 2s interval. OpenAPI regenerated; ring pagination/eviction, layer wiring, and the authed route are unit-tested; Storybook story included. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
