### Nix Package Hash (`pnpmDeps`)
18
+
19
+
`nix/package.nix` contains a `hash =` for `pnpm_9.fetchDeps`. This hash must be updated every time `pnpm-lock.yaml` changes.
20
+
21
+
**Why it changes:** `pnpm_9.fetchDeps` is a Nix fixed-output derivation (FOD) that downloads packages via pnpm in a sandbox. When the lockfile changes, the set of downloaded packages changes, so the hash changes. Platform-specific optional packages (e.g. `@esbuild/linux-arm64`) mean macOS and Linux produce different hashes — the hash in the repo must match what the Linux build produces.
22
+
23
+
**How to update it:** Run the helper script **on a Linux machine** (or with a Linux remote Nix builder configured):
24
+
25
+
```sh
26
+
pnpm nix:update-hash
27
+
# or directly:
28
+
bash scripts/update-pnpmdeps-hash.sh
29
+
```
30
+
31
+
The script:
32
+
1. Replaces the current hash with `lib.fakeHash` (a known-invalid placeholder)
33
+
2. Runs `nix build .#packages.x86_64-linux.default` — which fails with the correct hash in the error
34
+
3. Parses that hash and writes it back to `nix/package.nix`
35
+
36
+
**On macOS without a Linux builder:** Push your branch to CI, copy the correct hash from the build failure output, and update `nix/package.nix` manually.
