Pre-build acceptance observation

• RED: architecture-module (ARCHITECTURE.md)

intent: The completed build contains the declared Go module and command boundary. return code: 1 stderr: Traceback (most recent call last): File "architecture-module.py", line 6, in <module> assert module.is_file() ^^^^^^^^^^^^^^^^ AssertionError

• RED: architecture-dependencies (ARCHITECTURE.md)

intent: The Go module has no third-party dependency declarations. return code: 1 stderr: Traceback (most recent call last): File "architecture-dependencies.py", line 3, in <module> module_text = Path("go.mod").read_text(encoding="utf-8") ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/barlo/.local/share/uv/python/cpython-3.12.13-linux-x86_64-gnu/lib/python3.12/pathlib.py", line 1027, in read_text with self.open(mode='r', encoding=encoding, errors=errors) as f: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/barlo/.local/share/uv/python/cpython-3.12.13-linux-x86_64-gnu/lib/python3.12/pathlib.py", line 1013, in open return io.open(self, mode, buffering, encoding, errors, newline) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

• RED: architecture-command-build (ARCHITECTURE.md)

intent: The declared decoder command builds successfully. return code: 1 stdout: go: cannot find main module, but found .git/config in /mnt/c/Users/barlo/projects/drydock to create a module there, run: cd ../../../../../.. && go mod init stderr: Traceback (most recent call last): File "architecture-command-build.py", line 10, in <module> assert result.returncode == 0 ^^^^^^^^^^^^^^^^^^^^^^ AssertionError

Build summary

<reusable-compact filename="ARCHITECTURE.md"> Go module github.com/owner/toml-decoder uses standard library only. cmd/toml-decoder reads TOML from stdin, emits tagged JSON to stdout, reports invalid input on stderr, and exits non-zero. internal/toml owns parsing and explicit value kinds while preserving integer lexemes. </reusable-compact>

RESULT: SUCCESS

FILES CHANGED:

• go.mod
• cmd/toml-decoder/main.go
• internal/toml/value.go
• internal/toml/decode.go
• internal/toml/value_test.go

SUMMARY: Implemented the dependency-free Go module, parser boundary, decoder command, tagged JSON model, and focused tests. Go tests, vet, formatting, build, and all architecture acceptance checks pass.

BLOCKERS:

• None
