Translation Quality Review

PR: #18286
Branch HEAD: 1513336497
Languages in this PR: bn only (it and sw failed during pipeline; see below)
Files reviewed: 1 -- src/intl/bn/page-developers-tools-descriptions.json
Scope: Full file, ETHGlossary-grounded review
Date: 2026-05-27
Fixes: None applied (translation is structurally clean)

Summary

PR title says "(it, bn, sw)" but only the bn file actually landed -- the it and sw runs failed in the upstream Intl Pipeline workflow (run 26495825619, completed 2026-05-27 06:54). Failure analysis is captured separately; this review covers bn only.

bn translation is structurally clean and largely glossary-compliant. No critical issues. One systematic editorial deviation worth flagging.

bn quality details

• All 226 keys present, valid JSON (matches English source key count)
• Brand names preserved Latin across the file: Solidity (×59), Foundry (×16), Hardhat (×7), Optimism (×51), Uniswap (×12), Coinbase (×4), Arbitrum (×4), Polygon (×2), Etherscan (×5), IPFS (×12), GitHub (×2)
• Technical concepts transliterated per ETHGlossary:
  • blockchain -> ব্লকচেইন (×61) - matches glossary
  • smart contract -> স্মার্ট কন্ট্রাক্ট (×110) - matches glossary
  • network -> নেটওয়ার্ক (×28) - matches glossary
  • transaction -> ট্রানজ্যাকশন (×33) - matches glossary
  • block -> ব্লক (×73) - matches glossary
  • node -> নোড (×14) - matches glossary
  • wallet -> ওয়ালেট (×16) - matches glossary
  • validator -> ভ্যালিডেটর (×1) - matches glossary
• Large strings handle cleanly: tool-updraft-description (11,374 chars EN -> 26,595 Bengali bytes) translated faithfully
• No translated hrefs, no English-leak paragraphs, no cross-script contamination, no semantic inversions detected

Warning open (not auto-fixing)

Type	Detail
Cross-file consistency	Ethereum is kept in Latin for all 102 occurrences in this file. ETHGlossary mandates ইথেরিয়াম for bn, and other bn translations (e.g., page-staking.json on dev uses ইথেরিয়াম 19 times). Defensible editorial choice in a tool-listing context where Ethereum appears alongside other Latin brand names, but a real consistency drift across files. Worth a project-level call.

Quality scores (bn, page-developers-tools-descriptions.json)

Category	Score	Notes
Brand Name Preservation	10/10	All Latin brands preserved per glossary
Technical Accuracy	9/10	Glossary terms consistently rendered; only Ethereum-transliteration deviation
Semantic Fidelity	10/10	No inversions, all large strings preserved meaning
Terminology Consistency	9/10	Within-file consistent; cross-file Ethereum-form drift
Tone/Register	10/10	Natural Bengali technical register throughout

Overall: 9.6/10

Pipeline failure notes for it and sw (informational)

Both failures occurred in the same pipeline run (id 26495825619) but have different root causes:

• it: deterministic key drop. All 3 attempts on chunk 1/3 returned 99 keys instead of 100. Gemini is dropping or merging the same key each time -- not a timeout, not a size issue (chunk 1 is 43KB, well under the 64KB budget). Validation correctly retried, but couldn't recover from a content-level bug. Detailed analysis with mitigation patch in flight separately.
• sw: 300s timeout × 3 on chunk 2. sw expands output by ~1.5× relative to source; chunk 1 used 86% of the timeout window (258.6s) and succeeded; chunk 2 hit the 300s wall on every attempt. Hard GEMINI_TIMEOUT_MS cap in lib/llm/gemini.ts:1068.

Recommended mitigations (planned as separate PR):

1. Reduce MAX_CHUNK_BYTES from 65,536 -> 32,768 (halve chunk size). Pure structural fix.
2. Progressive chunking on validation failure: on the 3rd retry, split the batch in half and retry instead of giving up.
3. Better validation diagnostics: log which key(s) are missing on count mismatch (current log only says "got 99, expected 100").
