Build summary

RESULT: SUCCESS

FILES CHANGED:

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

SUMMARY: Implemented robust bare, quoted, and dotted key parsing; nested arrays; comments; mixed values; trailing commas; and malformed-input rejection. Added focused Go tests.

Validation passed:

• Key valid: 28/28
• Key invalid: 61/61
• Array valid: 21/21
• Array invalid: 26/26
• go test -race ./...
• go vet ./...

BLOCKERS:

• Full conformance still has unrelated failures in table lifecycle, floats, inline tables, integers, and strings outside this build block.
