## 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 has 62 valid and 33 invalid failures outside this scalar block.
- detail:
    Scalar-specific tests pass, but completing the full gate requires implementing arrays, tables, comments, strings, and datetime parsing in subsequent build blocks.

## Build summary
RESULT: FAILED

FILES CHANGED:
- internal/toml/toml.go
- internal/toml/toml_test.go

SUMMARY:
Implemented TOML booleans, canonical integers, base-prefixed integers, floats, exponents, special values, validation, and tests. Scalar suites pass; full suite remains failing in out-of-scope arrays, tables, strings, comments, and datetimes.

BLOCKERS:
- Full conformance suite is not yet green due to prior unimplemented parser features.

FAILURE_SUMMARY: Full conformance suite has 62 valid and 33 invalid failures outside this scalar block.
FAILURE_DETAIL: Scalar-specific tests pass, but completing the full gate requires implementing arrays, tables, comments, strings, and datetime parsing in subsequent build blocks.
