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.
