**Target operating model — recommended contracts, not installed collection.** All owner and cadence entries below are proposals to confirm before the pilot, not assigned responsibilities or approved schedules.
|
|
|
|
**Prototype calculation — no live telemetry.** The synthetic example calculates this metric; it has no network collectors.

Accepted changes with at least one confirmed post-acceptance defect during approved follow-up, split by severity.

| Numerator | Distinct eligible change_ids with one or more linked confirmed defects in follow-up |

| Denominator | Accepted change_ids with completed predeclared follow-up horizon |

| Eligible population | Accepted changes in acceptance window whose follow-up is complete by as_of. |
|
|
| Exclusions | Immature changes shown separately; duplicates/unconfirmed reports excluded but counted as pending triage. |
|
|
| Events and source | change.accepted; defect.confirmed; defect tracking and acceptance evidence |
|
|
| Owner / cadence | Quality Engineering / Monthly mature cohorts |
|
|
| Missing evidence | Unknown linkage is a coverage warning; no fabricated clean outcome. Show absolute defect and severe incident counts as well. |
|
|
| Gaming and limits | Shorten follow-up or downgrade severity; freeze horizon and rubric and independently sample defects. Descriptive signal, not causal AI productivity attribution. Source completeness, task mix and sampling limit inference; report uncertainty. Counts affected changes, not raw defects per change; no presumption defects are AI-caused. |
