 | rate limiting | **14 → adopting** | **Extracted 2026-08-20 as [`limitkit`](https://github.com/catomean/limitkit)** (see registry above). fleetcrown converted as the proving consumer; 13 files remain across 8 repos, orangecat first in line (its ADR-0002 becomes a 12-line `Store` adapter + three deletions). The ratchet holds the count until each adoption lands. |
 | AI provider client | **16** | evig 7, orangecat 5. `ai-kit` already owns the hard part (chain, 429, budget); these are the callers. **Priced 2026-08-26, re-priced 2026-08-27:** Groq retired the llama-3.x family and the damage was far wider than the first count. Seven repos were broken, not five — the audit could not see two of them — and inside a repo the id was written down **two to four times**. Kivvi took three PRs to remove one retired id: it lived in the provider registry, an app's inline fetch body, the fallback chain, and a client hook's `FALLBACK_MODEL`. Each pass only found the copies the tooling could see. That is the cost of duplication measured rather than argued. fleetcrown, which adopted the package, was unaffected throughout. |
 | logger | **10** | sbb-lost-found alone has 4. |
-| site-as-data (`sitekit`) | **2, by design** | The only row here justified by a *plan* rather than a count, and flagged as such. substrata expresses its pages as a closed union of section kinds rendered by presentational components; camille is the same product hand-rolled. Two is below the rule of three — but [the Site Factory](docs/site-factory.md) is a commitment to an Nth instance, and the extraction is what makes the generator emit **data against a schema** instead of `.tsx` against nothing. If that plan is dropped, drop this row rather than extracting on two. |
 | health route | **8** | Identical shape in 8 repos; a 20-line contract. |
 | ~~`@ai-native-cms/core`~~ | — | **Withdrawn — measurement error.** `catomean/revampit` *redirects* to `catomean/evig` (renamed in the pivot); the "two repos" with byte-identical trees were two clones of ONE repo. Nothing to extract. Two directories are not two repos: check `git remote -v` before reporting cross-repo duplication. |
