@bufferapp/bufflog is the logging library that Buffer services install. Its CI tests Node 18 and 20 only. Services are moving to Node 26.13.0, and nothing checks that the library works there.

This PR adds 26 to the node-version matrix in .github/workflows/ci.yml. Node 18 and 20 stay, because the library still supports them. package.json has no engines field, and the code needs no change, so I did not add one. The repo has no Dockerfile, .nvmrc or mise.toml. It does not call Corepack and has no native dependency.

I also left @types/node at 18.15.3. It only sets the types the compiler sees, and the build passes with it.

The blast-radius check looked at the CI matrix, engines, @types/node, Dockerfiles, version files, native dependencies and Corepack. Only the matrix needed a change. The runtime risk is pino 5 and pino-http 5 on a new Node. Both work: a clean npm ci, the tsc build and all 15 tests in 2 suites pass under Node 26.13.0.

Explanation

The title "build: upgrade Node to 26.13.0" matches the main change: the CI node-version matrix in .github/workflows/ci.yml gains Node 26 (26.13.0 per the description). The title is short, specific, and follows conventional commit style. It is slightly broader than the change, since the diff only adds Node 26 to the test matrix and keeps Node 18 and 20, so it does not upgrade the Node runtime for the library itself. That gap is minor and does not make the title misleading.

Full details: Description check

Explanation

The description matches the changeset. It explains that Node 26.13.0 is added to the CI node-version matrix in .github/workflows/ci.yml while Node 18 and 20 are kept. It also covers the reasons no engines field, Dockerfile, version file, or @types/node change was needed, and reports the local npm ci, tsc build, and test results under Node 26.13.0. The raw summary confirms the single one-line workflow change.
