Build reproducibility appears intact, but the promoted dependency graph was reconstructed from stale lineage metadata. The service still works through the primary path, but one dependency only fails when the old component is finally drained away.
A release workflow restores a cached dependency graph that no longer matches the promoted lockfile lineage during a staged decommission
Build reproducibility appears intact, but the promoted dependency graph was reconstructed from stale lineage metadata. The service still works through the primary path, but one dependency only fails when the old component is finally drained away.
Scenario
What to check first
- Identify the primary failure signal in the Dependency Graph Restored from the Wrong Lineage scenario.
- Separate visible symptoms from the underlying technical dependency.
- Describe the safest recovery path and the follow-up prevention work.
Checking checklist
- Summarize the current impact and the last known change.
- Collect direct evidence from logs, runtime state, and configuration before changing anything.
- Separate immediate recovery from permanent prevention work.
Recovery and prevention
Choose the smallest safe recovery action first, then record the prevention work that reduces repeat incidents.
Questions worth viewing together
No. Keep commands, logs, file names, APIs, and product names unchanged, then explain the reasoning in the selected UI language.
State the root cause, the evidence that supports it, and the safest recovery direction.
The source scenario is treated as an incident artifact. Guidance, checklist, hints, and explanations can be localized around it.
