- Around line 219-232: Update the TraceDetailPage call in the route to preserve
the total log count separately from the filtered logs, and use that total in the
trace header summary. Keep the filtered list for displaying logs; alternatively,
show both filtered and total counts when a filter is active.

Once a federated app has produced more than a few traces, it gets hard to find one failed activity or one noisy log category by scrolling. The traces list page gains a checkbox filter over the activity types it already displays, and the trace detail page gains a filter for its log table by category, level, and a case-insensitive text search. Both filters are plain GET forms, so they work without JavaScript and keep selections in the URL. The trace list's existing live-poll script now forwards the active filter to /api/traces so a filtered view does not trigger a reload loop from comparing against an unfiltered count. The issue's suggestion to also filter by delivery status or request path does not map to data the dashboard currently captures without extending FedifySpanExporter in the main package, so this stays scoped to what packages/debugger already has. fedify-dev#896 Assisted-by: Claude Code:claude-sonnet-5
Record the new filtering controls as a changes.d fragment under @fedify/debugger, and sync it into CHANGES.md's unreleased section. fedify-dev#896 Assisted-by: Claude Code:claude-sonnet-5
CodeRabbit's review on the PR raised two points. Issue fedify-dev#896 asks for tests that check the filtering behavior at the data boundary, not only rendered HTML, but /api/logs/:traceId had no filter support, so the log-filter tests could only assert on HTML. It now accepts the same category/level/q parameters as the trace detail page and filters before returning JSON, and a new test asserts on the parsed array. Separately, the trace header showed the filtered log count with nothing to say it excludes records outside the filter. It now shows "N of M log records" whenever a filter is active. fedify-dev#896 Assisted-by: Claude Code:claude-sonnet-5
Fedify 2.4.0 was released upstream while this branch was open, which moved the unreleased section to 2.5.0 and finalized the old one. Re-run sacho sync against the new base so the fragment lands under 2.5.0 instead of the already-released 2.4.0, and add this PR's number to the fragment's reference now that it exists. fedify-dev#896 Assisted-by: Claude Code:claude-sonnet-5

Please address the inline comments. Could you also update the trace-detail screenshot to show the current N of M log records count?

Could you use getLogLevels() from @logtape/logtape here? LogTape also supports trace, which this list omits. Trace-level logs are stored and can be filtered with ?level=trace, but users cannot select that level in the form. Using the API would keep the options in sync with the supported levels.

With Create selected, a newly captured Follow trace does not change the filtered count, so polling never reloads the page and the new Follow checkbox only appears after a manual refresh. Could you also detect changes to the available activity types when deciding whether to refresh, while keeping the active filter applied? Please add a regression test for this case.

This test is named “filters by category, level, and text search”, but the request only supplies level=error. Could you add JSON API assertions for category, case-insensitive text search, and their AND combination as well? That would cover these filters at the data boundary, as requested in #896.
dahlia pointed out that the hardcoded level list omitted "trace", which LogTape supports and the dashboard already stores and can filter by (?level=trace worked, but the dropdown had no option for it). getLogLevels() keeps the dropdown in sync with whatever levels LogTape supports, in severity order, without us tracking it by hand. fedify-dev#896 Assisted-by: Claude Code:claude-sonnet-5
dahlia found that with a filter active, a newly captured trace of a type outside that filter left the filtered count unchanged, so the poll never reloaded and the new checkbox only appeared after a manual refresh. The poll now always fetches the unfiltered trace list and compares the total count together with the full set of activity types across ticks, which also catches an existing trace gaining a new type in place, something a count-only comparison would miss. location.reload() keeps the active filter, since it reloads the same URL. There is no browser test harness in this repo, so the regression tests extract the rendered <script> body and run it in a sandbox with fake fetch/setInterval/location, then assert on whether reload() was called across simulated ticks. fedify-dev#896 Assisted-by: Claude Code:claude-sonnet-5
dahlia pointed out that "filters by category, level, and text search" only exercised level=error, so category, the text search, and their AND combination were untested at the JSON boundary that fedify-dev#896 asks for. Each now has its own test, matching the naming already used for the HTML-rendered log filter tests. fedify-dev#896 Assisted-by: Claude Code:claude-sonnet-5

Closes #896
Background
Once a federated app has produced more than a few traces, it gets hard to find one failed activity or one noisy log category in the debug dashboard by scrolling. This adds a small filtering surface to the traces list and to a trace's log table, without changing how trace or log data is stored.
Changes
Scope
The issue suggests filtering traces by status or path as one possible first version. Neither field exists on
TraceSummaryorTraceActivityRecordtoday: there is no request path captured anywhere, and the closest thing to a status, outbound delivery success or failure, is not captured either —FedifySpanExporteronly reacts toactivitypub.activity.sent, whichsend.tsonly emits after a successful delivery, so a failed delivery currently leaves no trace record at all. Making that filterable would mean extendingFedifySpanExporterin the main package to also captureactivitypub.delivery.failed, which is a bigger change than "a small filtering surface" in packages/debugger. I kept this PR scoped to what the dashboard already captures: activity type for traces, category/level/text for logs. Happy to open a follow-up issue for delivery-status capture if that is wanted.Testing

AI disclosure
This was implemented with Claude Code (
claude-sonnet-5). I picked the issue, decided to scope the filters to data the dashboard already captures instead of extendingFedifySpanExporter, and reviewed the design and the results at each step. Claude Code implemented the filtering logic, the UI, and the tests, and ran the checks and tests above on all three runtimes.
