Translation review: Tamil (ta) - Part 6 of 13

Reviewed 23 changed files in developers/docs/smart-contracts/, developers/docs/standards/, and developers/docs/storage/.

Scans performed

#	Scan	Result
1	Crowdin double-apostrophe artifacts ('')	Clean - only legitimate empty strings in ABI JSON code blocks
2	Tamil brand transliterations (எதீரியம்)	2 occurrences in testing/index.md - acceptable (common Tamil transliteration of "Ethereum")
3	Tamil inside code fences	324 lines - all are translated code comments or string literals matching English source pattern. Expected Crowdin behavior
4	Cross-script contamination (Devanagari/Telugu)	1 issue found and fixed - Telugu "ఇది" (U+0C07 U+0C26 U+0C3F) in security/index.md:41, replaced with Tamil "இது"
5	Broken markdown links	Clean
6	Split inline HTML (MDX risk)	Clean
7	JSON validation	N/A (no JSON files changed)
8	Escaped markdown (\*\*)	4 issues found and fixed across 3 files
9	Broken URLs	Clean
