Replace the developer-specific absolute policy path.
Line 30 points to /Users/jstuart/scratch_pad/.... The CHI source fails to load on any other checkout. Then validate.sh and setup-golden.sh (which copies this file) break for every other user. Use a path that validate.sh resolves at runtime. One option: keep a template and substitute $demo/policy in setup-golden.sh. Another option: use a path relative to the repository root.

Risk Assessment: moderate (2/5) DetailsLarge feature PR (29 files, 2227 lines, change-size composite 5) introduces entirely new Cosign-signed filesystem evidence verification capability, but no protected paths, no security-sensitive path flags, no CI or dependency changes, adequate test coverage (ratio 0.21), and an established contributor drive all other Tier 1 dimensions to 1-2; Tier 2 is suppressed by the majority of files being new with no churn history, yielding composite 0.621.875 + 0.381.0 = 1.54, rounded to 2 (moderate). |

[high] code-organization
Line 30 commits a hardcoded absolute path to a developer local machine (/Users/jstuart/scratch_pad/ec-cli-evidence-poc/hack/evidence-poc/policy), making the file non-functional for any other user or CI environment. All other hack/ scripts derive paths from BASH_SOURCE or $root; a committed static config file must not encode a machine-specific path. Compounding this, hack/evidence-poc/README.md lines 8-10 contain stale developer-workstation metadata (The worktree is /Users/jstuart/scratch_pad/..., The original checkout is unchanged. Changes are uncommitted.) and line 28 instructs the reader to cd into that same absolute path, so the README that advertises the POC as reproducible points at paths that only exist on the author laptop.
Suggested fix: Replace the absolute policy path with a repo-relative path that the policy loader can resolve (e.g. ./hack/evidence-poc/policy), or generate policy.yaml at runtime from setup.sh (which already produces generated/policy.yaml) and remove the static copy from version control. Separately, rewrite the README header and the cd example so they do not reference /Users/jstuart/scratch_pad.
