Bug warranty, new work, and operations are different
| Issue type | Typical example | Default classification | Evidence needed |
|---|---|---|---|
| Original delivery bug | An accepted workflow produces the wrong result under the supported environment | Bug warranty if reproducible and attributable to delivered code | Acceptance baseline, reproduction steps, logs, and affected version |
| New or changed requirement | New approval rule, report, role, or integration | New development request | Change description, business value, scope, and estimate |
| Third-party or environment change | Platform API, OS, browser, certificate, or cloud policy changed | Adaptive maintenance; assess responsibility and effort | Change notice, support matrix, impact analysis |
| Operations incident | Capacity exhaustion, expired account, misconfiguration, attack, or data restore | Operations / SLA matter, not automatically a code warranty | Monitoring, change log, account owner, backup and incident record |
