-Set `engines.node` to `^22.19.0 || >=24.0.0` and test keyless CI on `['22.19', 24, 26]`. The primary Node 24 jobs own the complete typecheck and unit coverage inventory; every version runs focused source-worker, Zstandard, source-launch, and [jsdom storage](../../archived/testing/2026-07-30-vitest-jsdom-webstorage-ownership.md) smokes without repeating that inventory. The real-API e2e workflow stays on Node 24 because it exercises API integration rather than the runtime floor.

+Windows PR coverage uses Node 26.10.0, which includes the [cppgc Realm cleanup fix](https://github.com/nodejs/node/pull/65778). Windows build and native-process checks use Node 24. Moving coverage back requires a Node 24 release containing the [pending backport](https://github.com/nodejs/node/pull/66168); the full test inventory, isolation and coverage thresholds remain required.

## Consequences
- The advertised LTS branch no longer undercuts the Pi adapter dependency floor.

- The built-mode smoke needs no version-conditional flag: at 22.19 type-stripping is already the default, so the example-owned TypeScript driver stays a plain `node fixture.ts` path.
- A future dependency or source API that raises the runtime floor must move `engines.node`, the compatibility matrix, and this Agent Note in the same change.
