Build summary

RESULT: SUCCESS

FILES CHANGED:

• internal/toml/decode.go
• internal/toml/value_test.go

SUMMARY: Implemented key uniqueness, scalar/table closure rules, nested inline tables, dotted inline keys, strict trailing-comma and newline validation. Scoped acceptance slices and Go tests pass.

BLOCKERS:

• Full conformance suite still reports unrelated pre-existing failures outside this build block.
