- Exact error message and exit code
  - go: github.com/halfrost/LeetCode-Go/ctl/models@v0.0.0-20220910225043-e3bb5aff34d0 (replaced by ./ctl/models): reading ctl/models/go.mod: open /workspace/ctl/models/go.mod: no such file or directory
  - ERROR: failed to build: failed to solve: process "/bin/sh -c go mod download" did not complete successfully: exit code: 1

- Failing command/step
  - [builder 4/6] RUN go mod download

- Missing packages or files mentioned
  - Missing file: /workspace/ctl/models/go.mod
  - The module is declared as replaced by ./ctl/models, implying a local path that is not present in the build context at this step

- Version mismatch / related version info
  - Base images used: golang:1.19-buster and Debian bullseye-slim
  - The error references a pseudo-version: v0.0.0-20220910225043-e3bb5aff34d0, replaced by ./ctl/models
  - No explicit version mismatch reported; the issue is the missing local path for the module replacement

- Context note (implicit cause)
  - go.mod contains a replacement "replaced by ./ctl/models" but only go.mod/go.sum were copied before the failing step; the rest of the code (ctl/models) isn’t in the build context yet, so /workspace/ctl/models/go.mod cannot be found.
