-- **Runtime**: Bun (Node 22 is enforced by a `preinstall` check)
+- **Runtime**: Bun (Node 22 or newer is enforced by a `preinstall` check)
+
+  That check demanded *exactly* 22 until 2026-08-12. The reason was a `node-pty` build
+  failure some months earlier, whose details were not recorded. It was relaxed to `>= 22`
+  after confirming node-pty ships **no Linux prebuilds** — its install script always falls
+  through to `node-gyp rebuild`, so it compiles against whatever Node is present and there
+  is no ABI to mismatch. Untested on 24 at the time of the change. If `bun install` fails
+  building node-pty, or `officer-pty` cannot load its native module, restore the exact pin
+  first. The source build also needs `build-essential` and `python3`.
 - **Language**: TypeScript, strict. `bunx tsgo` is clean — keep it that way.
