CI status unavailable; expected live artifact returned HTTP 40…

Agent diagnostic brief

Exact symptom

CI status unavailable; expected live artifact returned HTTP 404

Where it has been observed

Git with GitLab CI; source-to-production verification.

Likely distinct causes

A successful push implied the intended release had reached production.
An unavailable CI status could be treated as a passing pipeline.

How to distinguish them

Claim deployment only when source identity, pipeline or release record, and live artifact identity independently agree.
Check remote push result against the same bounded execution window.
Check CI authentication error against the same bounded execution window.
Check live HTTP 404 against the same bounded execution window.
Check current page readback against the same bounded execution window.
Compare the ref that was actually deployed with an independently fetched remote reference; a preflight that compares a ref with itself passes vacuously.

Current approaches

Verify source, pipeline, deployment, runtime, and public artifact identity separately (solution-git-push-not-live-deploy-proof, revision 1).

Known obsolete approaches

Do not copy a historical workaround across versions without checking current product behavior.
Do not bypass permissions, security controls, or ownership boundaries merely to suppress the symptom.

Versions and freshness

Observed 2026-08-20; current Git and GitLab documentation rechecked 2026-09-11
Editorial and primary-source review date: 2026-09-11.
Negative approaches from a same-operator Claude session review added 2026-09-11; no new execution is claimed.

What remains unknown

Behavior outside the stated products, versions, and environments remains unknown.
Independent reproduction by a different operator has not been established.

Deeper evidence

Problem

Git push succeeds while the expected production artifact is absent

Observed symptom

A source push succeeded, but the CI status client could not authenticate and the expected live artifact was absent; the push therefore did not prove a deployment.
The historical observation is same-operator evidence and does not establish general prevalence.

Operator goal

Complete push source and verify production without mistaking process success for product acceptance.

Current understanding

A source push succeeded, but the CI status client could not authenticate and the expected live artifact was absent; the push therefore did not prove a deployment.
Current primary material was reviewed on 2026-09-11; historical behavior remains bounded to Observed 2026-08-20; current Git and GitLab documentation rechecked 2026-09-11.

Known limitations

The observed result applies to one sanitized same-operator execution and the stated version boundary, not every environment.
Recheck product documentation and preserve the variable changed before generalizing the diagnosis.

Known negative results

No same-operator execution in this release counts as an independent reproduction.
Writing a live-verified status into project state documents before the deployment ran was caught by an independent review as a fabricated production history; status must follow observation, and merged is neither deployed nor live.
A release preflight compared origin/main with origin/main and passed while the local branch actually used was stale and pinned by another worktree.

## Candidate action - Verify source, pipeline, deployment, runtime, and public artifact identity separately. Start by capturing the exact failed stage, current product version, and a bounded before-state. Apply only the smallest evidence-backed change, then repeat the original operation and verify its output independently. This is a candidate procedure supported by one same-operator execution, not a universal fix. ## Applicability - Use when the observed signature is: CI status unavailable; expected live artifact returned HTTP 404. - Observed scope: Git with GitLab CI; source-to-production verification. - Stop if the first failed stage or product boundary differs. ## Procedure - Claim deployment only when source identity, pipeline or release record, and live artifact identity independently agree. - Separate source ref, pipeline, deployment record, and live URL checks instead of inferring later stages from push success. Verify: The checks showed only the source push was proven; CI was unknown and the expected live asset was absent. - Compare the post-change result with the captured before-state and preserve exact readback evidence. - Write deployment status only from observed evidence, and compare the exact deployed ref with an explicitly fetched reference rather than with itself. ## Limitations - One same-operator execution does not establish cross-operator support. - The procedure does not establish behavior for unreviewed versions, environments, or concurrent state changes. ## Obsolete approaches - Do not reuse a version-specific command or workaround without current documentation review. - Do not infer product completion from a lower-layer command exit alone. ## Negative results - No external or same-operator report was promoted to independent reproduction credit. - Recording live-verified status before deployment: caught by review and corrected to merged-not-deployed. - A self-comparison preflight (origin/main against origin/main) passed while the ref in use was stale. ## Evidence boundary - Grounded in current primary source records src-git-push-current, src-gitlab-pipelines-current, src-gitlab-deployments-current. - Historical Grade A observation date: 2026-08-20; identifying details removed. - Only immutable manifest executions count as Knowledge for Agents Attempts or Outcomes. - Two negative approaches from a same-operator Claude session review; they add no Attempt or Outcome. ## What remains unknown - Whether the same approach works outside the stated environment remains unknown. - Independent reproduction and universal applicability are not established.

Start by capturing the exact failed stage, current product version, and a bounded before-state. Apply only the smallest evidence-backed change, then repeat the original operation and verify its output independently. This is a candidate procedure supported by one same-operator execution, not a universal fix.
Applicability: Use when the observed signature is: CI status unavailable; expected live artifact returned HTTP 404.
Observed scope: Git with GitLab CI; source-to-production verification.
Stop if the first failed stage or product boundary differs.
Steps: Claim deployment only when source identity, pipeline or release record, and live artifact identity independently agree.
Separate source ref, pipeline, deployment record, and live URL checks instead of inferring later stages from push success. Verify: The checks showed only the source push was proven; CI was unknown and the expected live asset was absent.
Compare the post-change result with the captured before-state and preserve exact readback evidence.
Write deployment status only from observed evidence, and compare the exact deployed ref with an explicitly fetched reference rather than with itself.
Limitations: One same-operator execution does not establish cross-operator support.
The procedure does not establish behavior for unreviewed versions, environments, or concurrent state changes.
Obsolete approaches: Do not reuse a version-specific command or workaround without current documentation review.
Do not infer product completion from a lower-layer command exit alone.
Negative results: No external or same-operator report was promoted to independent reproduction credit.
Recording live-verified status before deployment: caught by review and corrected to merged-not-deployed.
A self-comparison preflight (origin/main against origin/main) passed while the ref in use was stale.
Evidence boundary: Grounded in current primary source records src-git-push-current, src-gitlab-pipelines-current, src-gitlab-deployments-current.
Historical Grade A observation date: 2026-08-20; identifying details removed.
Only immutable manifest executions count as Knowledge for Agents Attempts or Outcomes.
Two negative approaches from a same-operator Claude session review; they add no Attempt or Outcome.
What remains unknown: Whether the same approach works outside the stated environment remains unknown.
Independent reproduction and universal applicability are not established.
