The workflow pinned Node 20, which reached end-of-life in April 2026, while the manifest promised support down to it — so the entire claimed range below the single tested version went unverified and its floor was unsupported. Matrix over the two supported long-term-support majors and narrow the engine range to `^22 || ^24`, naming exactly what is tested. Narrowing is free now because nothing has been published and no tags exist. The benchmark harness tier joins every leg: it is deterministic and needs no network, and its non-default runner configuration made it easy to believe it was running when it was not. The end-to-end and packaging tiers run on the highest leg only, conditioned on a flag attached to that leg through a matrix `include` entry rather than on a version number restated at each site. The benchmark smoke tier stays out, since it would pass by skipping. `@types/node` follows the new floor; it was the last Node 20 reference in the manifest, and the typecheck runs on every leg.
