Pre-build acceptance observation

• GREEN (prepassed): invalid-exit-status (FEATURE-Decoder-Invalid-Input.md)

intent: Malformed TOML exits non-zero. return code: 0

• GREEN (prepassed): invalid-diagnostic-stream (FEATURE-Decoder-Invalid-Input.md)

intent: Malformed TOML produces a non-empty diagnostic on stderr. return code: 0

• GREEN (prepassed): invalid-no-success-result (FEATURE-Decoder-Invalid-Input.md)

intent: Malformed TOML does not produce a successful JSON result on stdout. return code: 0

Post-build programmatic acceptance

• PASS: invalid-exit-status (FEATURE-Decoder-Invalid-Input.md)

intent: Malformed TOML exits non-zero. target interpreter: /mnt/c/Users/barlo/projects/drydock/.venv/bin/python3 provisioning: not required return code: 0

• PASS: invalid-diagnostic-stream (FEATURE-Decoder-Invalid-Input.md)

intent: Malformed TOML produces a non-empty diagnostic on stderr. target interpreter: /mnt/c/Users/barlo/projects/drydock/.venv/bin/python3 provisioning: not required return code: 0

• PASS: invalid-no-success-result (FEATURE-Decoder-Invalid-Input.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: Full conformance suite remains incomplete.
• detail:

Existing parser behavior fails unrelated TOML syntax and semantic cases; broader parser implementation is required before the full-suite gate can pass.

Build summary

RESULT: FAILED

FILES CHANGED:

• cmd/toml-decoder/main_test.go

SUMMARY: Added process-level coverage proving malformed TOML exits non-zero, writes stderr diagnostics, and emits no stdout. Targeted tests, race tests, vet, formatting, and direct acceptance checks pass.

BLOCKERS:

• Full toml-test v2.2.0 suite fails: 47 valid and 129 invalid cases failed.

FAILURE_SUMMARY: Full conformance suite remains incomplete.
FAILURE_DETAIL: Existing parser behavior fails unrelated TOML syntax and semantic cases; broader parser implementation is required before the full-suite gate can pass.
