Each step's exporter.clear()/records.length = 0/fetchMock.hardReset() sat after its assertions, so a setup, dispatch, or assertion failure would skip them. Since the span exporter and log buffer are shared across all four steps, a mid-step failure would leak stale spans and log records into the next step, which can turn one real failure into several misleading ones. fedify-dev#1205 (comment) Assisted-by: Claude Code:claude-sonnet-5

Same issue as the sendActivity() alignment steps: each step's own exporter.clear()/records.length = 0 sat after its assertions, so a setup, dispatch, or assertion failure would skip it and leak stale spans and log records into the next step via the shared exporter and log buffer. fedify-dev#1205 (comment) Assisted-by: Claude Code:claude-sonnet-5

The concurrent-deliveries step only compared each log's spanId against its span. Add the matching traceId check for both logs, without assuming the two deliveries' traceIds must differ from each other -- only that each log matches its own span. fedify-dev#1205 (comment) Assisted-by: Claude Code:claude-sonnet-5

If one sendActivity() call failed before reaching the mocked handler (e.g. an earlier validation error), its counter increment never happened, so the other call's handler stayed blocked on `await gate` forever -- confirmed by forcing this path, which hung with Deno reporting a dangling pending promise. Attach .finally(release) to each dispatch so the gate opens once either settles, regardless of whether it ever reached the handler. allSettled already waited for both, so this closes the only remaining path to a stuck test. fedify-dev#1205 (comment) Assisted-by: Claude Code:claude-sonnet-5

Forced an early rejection on one dispatch to check this path: Promise.all rejected as soon as it did, which would let the step's finally clear the shared exporter/records while the other dispatch was potentially still mid-flight, and -- separately -- that other dispatch's listener could stay blocked on `await gate` forever if its own counter increment never happened. Switch to Promise.allSettled so cleanup only runs after both dispatches actually finish, and attach .finally(release) to each so the gate opens regardless of how either settles. These two changes have to land together: allSettled alone still leaves the gate closed if one side fails early, and .finally(release) alone doesn't stop Promise.all from moving on while the other call is still running. fedify-dev#1205 (comment) Assisted-by: Claude Code:claude-sonnet-5

Could you rebase your commits on the latest main branch? Thanks!
LogTape's withContext() was only refreshed at the two outer
boundaries of federation processing: Federation.fetch()'s own HTTP
request span, and the queue worker's consumer span opened by
#runWorkerSpan()/processQueuedTask(). It was never refreshed when a
deeper, operation-specific span was opened for an individual
delivery (activitypub.send_activity) or inbox request
(activitypub.inbox), so logs emitted inside those spans still
carried the enclosing worker's or request's traceId/spanId instead
of their own -- the same IDs a TraceActivityRecord derived from that
span would carry.
Scope the LogTape context to those two span-creation sites using the
same withContext({traceId, spanId}, ...) pattern already used at the
outer boundaries. AsyncLocalStorage-backed withContext() restores
the outer context automatically once the inner callback settles, so
no manual save/restore was needed.
Add regression tests that exercise real sendActivity(), handleInbox(),
and processQueuedTask() calls and compare the logs they actually
emit against real OpenTelemetry spans and, where one exists, a real
TraceActivityRecord extracted via FedifySpanExporter -- including
restoration after success and after a thrown error, isolation
between genuinely concurrent operations, and preservation of
existing context properties such as requestId and messageId. A
delivery that never succeeds has no persisted record at all, since
FedifySpanExporter only derives one from the "sent" event that
sendActivityInternal() adds on success; that failure case is
verified against the delivery span itself instead, with the record's
absence asserted explicitly.

These comments restated what the surrounding code and test names already make clear, and the design rationale they carried (event timing for TraceActivityRecord creation, outer-context restoration semantics) is already covered in the pull request description.

Summary
activitypub.send_activityfor outbound delivery,activitypub.inboxfor inbound processing), instead of leaving it pinned to the enclosing HTTP request's or queue worker's span.traceId/spanIdinstead of the outer worker's or request's.Closes #1030
Why
TraceActivityRecord.spanIdis extracted from the span that carries theactivitypub.activity.sent/receivedevent. LogTape'swithContext(), however, was only called at the two outer boundaries —Federation.fetch()'s own HTTP request span, and the queue worker's consumer span in#runWorkerSpan/processQueuedTask()— and never refreshed when a deeper, operation-specific span was opened. A failed delivery's error log (logged from insidesendActivity()'s own span) therefore still carried the enclosing queue worker's span ID. Same issue for inbound processing insidehandleInbox().This is the federation-instrumentation half described in #1030. It doesn't touch #902's debugger log storage, serialization, or rendering, and doesn't change the trace/span hierarchy — it only adds
withContext({traceId, spanId}, ...)at the two span-creation sites, reusing the pattern already used inmiddleware.ts's#runWorkerSpan/fetch(). LogTape 2.2'swithContext()isAsyncLocalStorage-backed, so nested calls automatically restore the outer context once the inner callback settles.Note an asymmetry that's inherent to the existing instrumentation, not something this PR changes:
FedifySpanExporteronly persists aTraceActivityRecordwhen the span carries theactivitypub.activity.sent/receivedevent.sendActivityInternal()adds that event only after a successful response, so a delivery that fails on every attempt never gets a persisted record at all. This PR's tests verify the failure log'straceId/spanIdagainst the delivery span itself (not a record, since none exists) and explicitly assert that no record is persisted for that trace.#1257 tracks persisting failed outbound delivery attempts, including typed outcome data and retry/summary semantics. #902 will use those records to display outbound failures with their related logs. This PR remains scoped to logging-context alignment; #1030's validation now compares logs with operation spans and with activity records when they exist.
Testing
Regression tests exercise real federation operations (
sendActivity(),handleInbox(),FederationImpl.processQueuedTask()) and compare the logs they actually emit — captured through a real LogTape sink withAsyncLocalStorage-backedcontextLocalStorage— against real OpenTelemetry spans and, where one would exist, a realTraceActivityRecordextracted viaFedifySpanExporter. No test asserts on manually-matched IDs. Outer-context restoration is checked against an explicit sentineltraceId/spanId(not just “differs from the inner span”), and concurrency tests synchronize two in-flight operations via a shared gate rather than relying on timing.send.test.ts: a warning logged during a successful delivery matches the resultingTraceActivityRecord; a failed delivery's error log matches its own span — not a record, since none is created for a delivery that never succeeds, which the test also confirms explicitly; outer context is restored after both a successful send and a thrownSendActivityError; two genuinely-overlapping concurrent deliveries don't leak each other's span IDs.handler.test.ts: a listener failure's log matches the real inboundTraceActivityRecord; outer context is restored after both successful and failed processing; two genuinely-overlapping concurrent inbox requests don't leak context.middleware.test.ts: a fullprocessQueuedTask()run for a failing outbox message shows the delivery's own log matching the delivery span, while the worker's own retry-decision log (logged after the delivery span already ended) keeps the real outeractivitypub.outboxworker span's ID — both preservemessageIdand an outer custom context property.All three test files were confirmed to fail before this fix and pass after it (verified by stashing just the
send.ts/handler.tschanges and re-running).Ran
