Pre-build acceptance observation

• GREEN (prepassed): decoder-valid-stdin (FEATURE-Decoder-Contract.md)

intent: A valid TOML document is accepted through stdin and produces a JSON object. return code: 0

• RED: decoder-argument-free (FEATURE-Decoder-Contract.md)

intent: Supplying an argument is rejected by the argument-free command contract. return code: 1 stderr: Traceback (most recent call last): File "decoder-argument-free.py", line 9, in <module> assert result.returncode != 0 ^^^^^^^^^^^^^^^^^^^^^^ AssertionError

• GREEN (prepassed): decoder-stream-separation (FEATURE-Decoder-Contract.md)

intent: Successful decoding does not write diagnostics to stderr. return code: 0

Post-build programmatic acceptance

• PASS: decoder-valid-stdin (FEATURE-Decoder-Contract.md)

intent: A valid TOML document is accepted through stdin and produces a JSON object. target interpreter: /mnt/c/Users/barlo/projects/drydock/.venv/bin/python3 provisioning: not required return code: 0

• PASS: decoder-argument-free (FEATURE-Decoder-Contract.md)

intent: Supplying an argument is rejected by the argument-free command contract. target interpreter: /mnt/c/Users/barlo/projects/drydock/.venv/bin/python3 provisioning: not required return code: 0

• PASS: decoder-stream-separation (FEATURE-Decoder-Contract.md)

Agent self-report (advisory)

The build agent declared a failure. This is advisory only; the programmatic acceptance above is the authority for this block's outcome.

• summary: Authoritative conformance suite failed.
• detail:

sh sources/full_test.sh completed with exit status 1 due to remaining parser grammar and table-semantics failures. Further TOML 1.0 parser implementation is required.

Build summary

RESULT: FAILED

FILES CHANGED:

• cmd/toml-decoder/main.go
• cmd/toml-decoder/main_test.go
• internal/toml/decode.go

SUMMARY: Implemented stdin decoding, tagged JSON output, argument rejection, diagnostics, structured values, tables, arrays, and process-level tests. Unit tests and go vet pass.

Full conformance: 158 valid passed / 47 failed; 345 invalid passed / 129 failed.

BLOCKERS:

• Full TOML 1.0 conformance is not yet passing.

FAILURE_SUMMARY: Authoritative conformance suite failed.
FAILURE_DETAIL: sh sources/full_test.sh completed with exit status 1 due to remaining parser grammar and table-semantics failures. Further TOML 1.0 parser implementation is required.
