Error message

pinned GitNexus runtime component is unavailable: {source}: {exc}

What it means

Raised by _validated_runtime_component (runtime_mounts.py:160-164) when lstat() or resolve(strict=True) on a specific runtime component path (e.g. gitnexus/dist, gitnexus/package.json, gitnexus/node_modules, gitnexus/vendor, gitnexus/hooks/claude, gitnexus-shared/dist, gitnexus-shared/package.json) raises OSError. The source path reported is root/relative.

Solutions

1. Build the package: `cd gitnexus && npm install && npm run build` (and same for gitnexus-shared).
2. Confirm the named source file exists: `ls -l <source>`.
3. Restore vendor/ via the documented vendoring step if missing.
4. Check read permissions on the path.

from pathlib import Path
source = Path(root) / relative
if not source.exists():
    raise SystemExit(f"runtime component missing: {source}")

from pathlib import Path
def component_exists(root: str, relative: str) -> bool:
    return (Path(root) / relative).exists()

When it happens

Trigger: The dist build output is missing (not built); node_modules absent (npm install not run); vendor directory missing; package.json unreadable (EACCES/ENOENT); a component path broken.

Common situations: Fresh clone without `npm install`/`npm run build`; a partial checkout; CI caching node_modules incorrectly; deleted vendor artifacts.
