Yarn Berry 4.1.0 via corepack, macOS 25.6.0 (darwin arm64), Node 24.13.0.
Run 2026-09-12 on Arpit's Mac, in Claude Code, by the session that built W-149.

ARM 1 — nodeLinker: node-modules
  yarn workspaces list           .  /  .fux/node  /  packages/app     <- member LINKED
  install                        Fetch + Link completed, 1s 055ms
  node_modules/.bin/fux          PRESENT   -> ../fux-engine/fux.mjs   (hoisted to ROOT)
  .fux/node/node_modules/.bin    absent
  shim rung that resolves        3  (the ancestor walk)

ARM 0 — does the dot path link at all (no dependency declared)
  nodeLinker: node-modules       .  /  .fux/node  /  packages/app     <- LINKED
  nodeLinker: pnp                .  /  .fux/node  /  packages/app     <- LINKED
  => the dot prefix is NOT a problem in Berry either, in either linker.

ARM 2 — nodeLinker: pnp  (Berry's DEFAULT when the key is unset)
  install                        Completed with warnings ("ESM support for PnP
                                 uses the experimental loader API")
  node_modules anywhere          NONE (find . -name node_modules -maxdepth 4 -> empty)
  .pnp.cjs                       present
  `corepack yarn fux --version`  did not resolve as a runnable script
  shim rung that resolves        NONE
