Standalone cmd that runs the same pipeline as the webhook notifications
(alerts.LoadErrorEvents -> alerts.DetectAlerts -> cooldown suppressor) on
a schedule and renders what is firing as a row of severity-colored cards -
built for an ultra-wide, low display. A pattern shows PAGED when the scan
would have notified and ongoing while suppressed; disappearing spikes are
reported as recovered. -once prints one snapshot for cron/pipe use.
Colors follow the otel-ui design-system tokens (dark and light).
- POST /v1/csp collects browser CSP reports in both wire formats (legacy
application/csp-report and Reporting API application/reports+json), with
CORS limited to the operator's domains (any subdomain of k6n.net,
tornberg.me, knatofs.se) and preflight handling.
- Reports are stored in a dedicated typed ClickHouse table (csp_reports,
90-day TTL) with a JSONL file fallback (OTEL_CSP_PATH).
- New authenticated view endpoints /api/csp/reports and /api/csp/summary
plus a 'CSP reports' screen in the UI (tab 12) with time window, site and
directive filters and report drill-down.
- Documented in instrumentation.md; unit tests for parsing/handlers/file
store and an env-gated ClickHouse integration test.
- Add static/otel-rum.js: a framework-free browser script that captures
uncaught errors, unhandled promise rejections and failed resource loads,
translating them into OTLP log records POSTed to the existing /v1/logs
endpoint (source: frontend attribute) so they flow through the same
history/search/issue pipeline as backend telemetry.
- Add correlation-id support: traceHeaders() (manual) and same-origin
fetch auto-instrumentation inject a W3C traceparent header, so a
frontend error and the backend spans it triggered share a trace id and
can be found together via GET /api/traces/{traceId}.
- Add CORS handling (withCORS in cmd/server/main.go) on the OTLP HTTP
endpoints, required for any browser-origin POST.
- Add an optional shared ingest key (OTEL_INGEST_KEY, via '?key=' or
X-Otel-Ingest-Key) and a per-IP rate limit (20 rps/burst 50) on OTLP
HTTP ingestion, to scope/protect a public endpoint fed by a browser
script. Verified end-to-end (CORS preflight, cross-origin POST, ingest
key enforcement, rate limiting) against a running server.
- Serve static/otel-rum.js and agents_example.md as static HTTP routes so
both the script and the agent instructions doc are fetchable directly
from the base URL.
- Ignore the separately-cloned otel-ui/ frontend repo (has its own .git;
not meant to be nested into this repo's history).

- Add internal/issues.Tracker: fingerprints (kind, service, title) into
deduplicated Issues with count/firstSeen/lastSeen/affected services and
bounded sample occurrences, evicting the least-recently-seen issue once
a cap is reached.
- Add internal/collector/issue_extract.go to pull issues out of ingested
OTLP data: spans with an error status (preferring exception.type/message
from an "exception" event, falling back to the span status message), and
logs at ERROR/FATAL severity (by severity number or text).
- Wire extraction into Collector.ConsumeTraces/ConsumeLogs and expose
GET /api/issues and GET /api/issues/{id}.
- Fix a pre-existing data race in the collector test's mockStore (unsynced
access to entries while addToHistory appends asynchronously), found via
`go test -race` while adding the new issue-tracking tests.
- Update docs/PLAN.md, README.md and agents_example.md for the new API.
The UI "Issues" tab itself lives in the separate frontend project that
builds this server's dist/ bundle; this commit only covers the backend.

- Fix /api/history/{type} to search the full persistent store instead of
only the bounded in-memory ring buffer, so filtered history isn't
silently truncated.
- Add structured type/since/until filters to /api/history/search and
/api/history/wait, alongside the existing free-text query.
- Add GET /api/traces/{traceId} to fetch all entries for a trace in one
call instead of relying on substring search.
- Rate-limit /api/history/wait per client IP.
- Add docs/PLAN.md tracking the phased improvement plan; update README
and agents_example.md for the new/changed endpoints.
