9- **Pantry-managed stable Zig**: run `eval "$(pantry env | sed -n '/^export /,$p')"`, then invoke `zig` (locally only — CI does not: the pantry action already puts `zig` on PATH, and `pantry env` runs a workspace setup that re-installs JS deps with its own `--linker`, rewriting `node_modules` mid-job)
9- **Pinned Zig toolchain**: use the exact snapshot in `pantry.lock`. Root `bun run build:core`, `test`, `fmt`, `run`, and `zig` scripts validate the selected compiler and print its path/version before use. Activate your Pantry environment locally, or set `CRAFT_ZIG=/absolute/path/to/zig` to a matching compiler. The scripts do not invoke `pantry env` automatically because it can reinstall workspace dependencies. CI receives the pinned toolchain from the Pantry action.
1010- **Bun**: Install from [bun.sh](https://bun.sh)
1111
12To intentionally test another Zig snapshot, use both an explicit compiler and the opt-in:
13
14```bash
15CRAFT_ZIG=/absolute/path/to/experimental/zig CRAFT_ALLOW_UNPINNED_ZIG=1 bun run build:core
16```
17
18This override is for compatibility testing; it does not change the checked-in lockfile.
