Issue
#61is an active direct target. The PR adds a shared bounded OTLP/HTTP exporter with drop counting, POST timeouts, failure isolation, and attribute sanitization. The three worker processes configure tracing fromSPACE_OTEL_EXPORTER_OTLP_ENDPOINTand shut down the exporter safely. Workflow and activity spans preserve trace parentage, child-workflow nesting, continuation links, allowlisted attributes, and replay suppression. The Temporal test environment and local collector test checks hierarchy, attribute filtering, and zero spans during replay. The PR adds no tracing runtime dependency and updates both required documents. The Jaeger check and screenshot are non-coding tasks.
Full details: Out of Scope Changes check
-
Explanation
The changes remain within issue
#61. The shared exporter, worker tracing interceptor and sinks, activity-attempt spans, worker lifecycle wiring, tests, and documentation implement or verify the issue. The API and runtime re-exports support the shared implementation. The PR does not add CLI Host or Browser Host spans, metrics or log export, sampling configuration, or trace-ID database columns.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Guard the exporter call so tracing cannot fail an activity.
finish runs inside the try block on Line 240. Suppose record or BigInt throws, for example because a clock override returns a non-integer now(). A successful activity then goes to the catch path. That path calls finish a second time and rethrows the error, so the activity fails.
The module header promises that export never fails activities. Wrap the span block in try/catch.

Propagate the workflow trace to the background-action activity.
roomAgentActionWorkflow starts with a memo traceparent, but its activity input contains only actionId, bridge, and traceId. The activity observer therefore finds no traceparent and falls back to the run ID, which places this activity span in a different trace.
Propagate the workflow traceparent through Temporal activity headers or expose it to activityCorrelation. The activity observer must receive the traceparent value; traceId alone is not sufficient.

Store the predecessor workflow trace and span IDs for background links.
sourceRunId is the application run ID, not the Temporal execution run ID used as the predecessor workflow span ID. A 16-hex slice of sourceRunId therefore cannot identify that span.
A copied traceparent keeps the new workflow on the predecessor trace, but it does not fix the span ID. A predecessor trace supplied only through workflow memo is not passed to the child workflow. Store the actual predecessor workflow trace ID and span ID in the continuation, and emit the link only when both IDs are valid. The 16-hex threshold and predecessor trace ID alone are not sufficient.

Use the current run start for workflow spans.
info.startTime is the start of the workflow execution chain. For a continueAsNew run, it can precede the current run. Use info.runStartTime so the workflow span does not include earlier runs. This affects the workflow span timestamp, not the activity-span title.

141-141: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winRemove the
spanExporteralias so activity span names are the same in every path.
spansandspanExporterare two options that select the same exporter. The span name depends on which option the caller uses:
- The three production workers pass
spans, so their spans are namedactivity <type>.- The integration test passes
spanExporter, so its spans are namedactivity:<type>.The test accepts both names. It therefore never checks the name that production emits. Workflow spans use
workflow:<type>, so the production activity name also differs from the workflow naming style.Keep one option and one naming format, and update the test to assert that exact name.
♻️ Proposed refactor
spans?: SpanExporter | null; - spanExporter?: SpanExporter | null; headerTraceparent?: string | null;- const exporter = dependencies.spans ?? dependencies.spanExporter ?? null; + const exporter = dependencies.spans ?? null;- const spanName = dependencies.spanExporter && !dependencies.spans - ? `activity:${activityType}` - : `activity ${activityType}`; + const spanName = `activity:${activityType}`;Before you change the name, check whether existing tests or dashboards expect

`ContinueAsNew` before setting `error`, track that outcome separately, and
rethrow it unchanged. Ensure continued runs receive a non-error workflow status
such as `CONTINUED_AS_NEW` and do not produce an OTLP error status; preserve the
existing failure handling for other errors.

Nitpick comments:
Review comments at @apps/worker/src/activity-observability.ts:
- Line 141: Remove the spanExporter alias from the activity observability
options and exporter selection, use a single activity span naming format across
all callers, and update the integration test to assert that exact name.

The memory workers keep the workflow tracing sinks and interceptors from this branch and gain main's deployed-code reload watcher, which is now stopped in the finally block together with the span exporter.

- Around line 17-22: Update the worker package scripts so running its tests
first builds @space/contracts; add a pretest step that runs the contracts
workspace build before the existing Vitest test script.

The workflow tracing interceptor imports @space/contracts, whose entry points at dist/, so a clean checkout failed to resolve it until the package had been built by hand. Build it in pretest.

Thank you for contributing and for sharing your work. This PR is awaiting maintainer review; the automated review does not replace that step. For the bounty issues, we review PRs in the order they were opened, under the terms on the issue. An earlier PR that misses an acceptance criterion does not block a later complete solution. Please include the checks you ran yourself, their results, your environment, and any limitations, if those details are not already in the PR. We appreciate the time you have put into this. |

Hi @oll4com, thank you for the reply, and I understand that ending a bounty programme can be a hard decision. Still, I would like to respectfully ask you to reconsider how it is applied to pull requests that were already submitted.
I would therefore kindly ask for at least partial compensation for the work submitted under the posted terms before the announcement, or a review of this PR under the original terms. I believe many other contributors on #60–#65 are in the same situation. For transparency: the code in this PR is public and dated. SpaceApp is MIT-licensed, which requires the copyright notice and attribution to be preserved. If any part of this solution is later used in Thank you for your time, and I hope we can find a fair solution. |
