Translation Quality Review

Language: Czech (cs)
Files reviewed: 24 (all files), 10 spot-checked thoroughly
Model: Claude Opus 4.6

Quality Score: 7/10

Category	Score	Notes
Brand Name Preservation	9/10	Solidity, Vyper, OpenZeppelin, Hardhat, Remix, Alchemy, Infura, Uniswap all preserved correctly
Technical Accuracy	7/10	require()/revert() strings were translated (now fixed); zk-rollups title was mistranslated as "zero-access" instead of "zero-knowledge" (fixed)
Naturalness & Fluency	8/10	Generally reads well as native Czech; good use of technical terminology
Terminology Consistency	7/10	Inconsistent "smart kontrakt" vs "chytry kontrakt" usage throughout, but this is a pre-existing pattern in the codebase

Issues Found and Fixed (10 files, commit 9125456)

Critical:

1. Translated code string literals - require(), revert(), and print() messages inside code blocks were translated to Czech. These must stay in English as they are runtime strings. Fixed in: smart-contracts/index.md, languages/index.md, libraries/index.md, security/index.md, erc-20/index.md
2. Mistranslated title - zk-rollups title "Rollupy s nulovym pristupem" (zero-access rollups) corrected to "Rollupy s nulovou znalosti" (zero-knowledge rollups)

Moderate:
3. Crowdin artifact - \#Dedičnost (escaped hash before "Inheritance") in languages/index.md list item
4. Duplicate headings - "Co to je smart kontrakt? Co je to chytry kontrakt?" in smart-contracts/index.md and similar in testing/index.md
5. Broken backtick formatting - ERC-20 page line 168 had garbled backtick placement around approve(..) & transferFrom(..) pattern

Minor:
6. Spelling error - "Standart" corrected to "Standard" in ERC-20, ERC-223, and ERC-777 page titles (common Czech misspelling of loanword)
7. Typo - "navcženo" corrected to "navrzeno" (designed) in storage/index.md

Summary

The Czech translations are generally of good quality with natural phrasing and correct preservation of brand names and URLs. The main systematic issue was Crowdin translating string literals inside code blocks (require/revert messages), which was fixed across 5 files. The zk-rollups title mistranslation was a notable accuracy issue. All issues have been fixed and pushed.
