- flake.nix: buildGoModule for quicknotes binary, dockerTools.buildImage for OCI - flake.lock: pins nixpkgs to nixos-25.11 rev b6018f87 (2026-06-30) - nix-repro.yml: two-parallel-job CI gate that fails on digest mismatch
…urce Temporarily adds a timestamp comment to app/main.go in Build B only, causing the Nix src hash to differ so verify-repro catches the mismatch.
Reverts the intentional divergence introduced in the previous commit. Both jobs now build identically; verify-repro should go green.
- docker: add extraCommands for seed.json and /tmp, set DATA_PATH/SEED_PATH env vars, use Nix store path in Entrypoint — container now actually runs - nix-repro.yml: add permissions: contents: read; guard against empty digests to prevent vacuous CI pass - submission: update sha256sum evidence and add docker run /health proof
