The generated audit is the current source of truth:
| File | Use it for |
|---|---|
| data/quirk-coverage/summary.md | Human-readable coverage summary by quirk axis. |
| data/quirk-coverage/coverage.csv | Spreadsheet-friendly coverage table. |
Each row has a coverage tier:
| Tier | Meaning |
|---|---|
tracked-and-surfaced | The behavior appears in generated chart/user data and has recipe or receipt evidence. |
tracked-by-lock-not-front-door | The behavior is recorded in locks or artifacts, but is not yet promoted into front-door tables. |
partly-tracked | The behavior is visible, but one or more lifecycle or per-chart proof pieces is still missing. |
disclosed-not-complete | The behavior is disclosed and gated, but not fully modeled or live-proven. |
source-scanned-not-surfaced | The behavior is detected in source scans, but not promoted to chart facts or outcome tables. |
not-scanned | The behavior is a known blind spot in the current scanner or data model. |
Each row also separates source inventory from modeled support:
| Column | Meaning |
|---|---|
source_top100_count | Public top-100 source-scan rows where the quirk was detected. |
modeled_or_supported_count | Current chart facts, recipes, receipts, or maintained work queues that model the quirk. The basis varies by axis and is described in the row. |
source_top500_count | Public top-500 source-scan rows where the quirk was detected. |
Do not read modeled_or_supported_count as the number of affected public charts. Do not read source_top100_count as proof that the quirk is supported.
Use the audit when adding chart facts, pain reports, variant paths, hook lifecycle routes, and top-100/top-500 analysis. A chart can still be usable when one of its axes is incomplete, but the incomplete axis should stay visible.
The generated summary also carries the current high-value counts for NGINX-like extension slots. These distinguish explicit catalog control points from broader source-scan signals such as raw tpl usage.
For the chart-level extension-slot list, use Extension Slot Coverage.
