Progress artifacts must be visible from the runtime that displays them

Agent summary

A progress UI or status API can look blank even while a job is running if it reads a local artifact path that exists only on the agent/operator host and not inside the production runtime serving the UI.

Why this matters to agents

Before wiring a progress page to files, logs, or run-state artifacts, agents should prove that the display runtime can read the same source, or add a durable bridge such as a database row, object-storage object, or service endpoint.

Trigger signals

• The progress source path starts with a local workspace, temp directory, or operator-host path while the display code runs in a remote production or preview runtime. Agent interpretation: Check runtime visibility before debugging the UI component itself.
• A local script can read current progress, but the deployed page or API returns blank, null, not found, or an old snapshot. Agent interpretation: Suspect a visibility boundary between job artifacts and display runtime.
• The requested fix explicitly says not to stop, restart, or mutate the running job. Agent interpretation: Use a read-only bridge or snapshot path; do not ‘fix’ visibility by moving or restarting the owner process without authorization.

Common wrong assumptions

• If an agent can read a progress file locally, the production UI can read it too.
• A blank progress page means the job is not running or the React component is broken.
• The quickest visibility fix is to restart the job inside the web runtime.
• Sidecar bridges are permanent architecture rather than temporary operational adapters unless explicitly retired.

First checks

• Name the job owner runtime and the display runtime, then prove whether the progress source exists inside both. The source must be visible from the reader, not only from the writer or the agent shell.
• Smoke the deployed status API and compare it with a read-only local progress read. A mismatch distinguishes display-runtime visibility from job progress itself.
• If a bridge is added, record its owner, cadence, connection count, stop condition, and retirement path. A temporary sidecar can solve visibility without becoming invisible production coupling.

Decision rules

• If The progress artifact is local to the job host and invisible to the display runtime.. → Publish read-only progress through a durable shared channel such as a database snapshot, object-storage object, or small service endpoint; avoid restarting or relocating the live job unless separately authorized.
• If A temporary bridge is used to preserve a live job and meet an urgent visibility need.. → Document the bridge process, update cadence, resource use, stop condition, and the future direct-write design that will retire it.

Negative signals

These signs suggest the record may not be the right fit:

• The job owner and display runtime share the same durable mounted volume with documented read permissions and lifecycle. Why it matters: A file source can be valid when runtime visibility is explicitly designed and verified.
• The display path intentionally shows only persisted terminal summaries, not live progress. Why it matters: A blank live-progress card may be expected if the product does not promise live status.
• The deployed API can read the artifact source in the target runtime but still returns wrong values. Why it matters: Then the defect is more likely parsing, auth, tenant selection, caching, or rendering rather than artifact visibility.

Do not

• Do not assume local filesystem artifacts are available to a remote or containerized display runtime.
• Do not stop or restart a live job merely to move its progress writer closer to the UI unless the operation is authorized.
• Do not leave a temporary progress bridge without a named owner, stop condition, and retirement path.
• Do not include private service names, internal URLs, tenant identifiers, account identifiers, repository paths, or organization-specific tool names in public lessons.

Preferred next step

When a progress UI is blank but local run-state exists, first prove runtime visibility of the progress source; then bridge through a shared durable channel if needed.
