Why

Two defects in the i18n pipeline stop pages from ever reaching "in sync". Both surfaced in today's sync run.

1. Oversized pages that have one H2 heading are never chunked

resolveChunkStrategy() only switches to section mode when a page has at least auto_chunk.min_sections (2) H2 headings. Generated Router pages carry a single ## Quick start heading above tens of thousands of characters of tabbed code, so they stay in whole-file mode and the whole page goes out in one API call. The response is always cut short, validateTranslatedBlock() rejects it, and the page keeps the old translation forever. That is why es/development/comfy-router/models/google/gemini/code.mdx was still in the previous single-schema layout while zh/ja/ko were current.

Fix: when a whole-file page exceeds WHOLE_FILE_PIECE_SPLIT_CHARS (40 000 characters), route it through the existing block path, which already splits oversized content into pieces with splitOversizedBlock() and concatenates the results. The frontmatter keeps its whole-file hash, so nothing changes for pages under the threshold (only 9 pages in the repo are above it, three of which are configured chunked files anyway).

2. The Spanish changelog date can never match

formatChangelogDateForLang() had no es case, so it fell through to the English format. hasChangelogDateDrift() then compared 4 de noviembre de 2026 (correct) against the expected November 4, 2026, reported drift for all 145 release blocks, and kept es/changelog/index.mdx permanently pending. Verified before/after with getSectionSyncStatus(en, es, "update_blocks", false, "es"): needsReserialize: true before, upToDate: true after.

Fix: add Spanish month names and the es case (${day} de ${month} de ${year}), matching how the es changelog already writes its dates.

Tests

bun test ./.github/scripts/i18n/: 131 pass, 0 fail. New cases cover the Spanish date format, the unchanged en/zh/ko formats, and a Spanish changelog block being reported as in sync.

Walkthrough

The translation script now routes non-Qwen whole-file sources over 40,000 characters through chunked translation. Changelog date localization now formats Spanish dates as day de month de year. Translated Tabs validation now requires opening and closing tag counts to match the English block.

Changes: Large-file translation

Layer / File(s)	Summary
Threshold and translation routing .github/scripts/i18n/chunked-translate.ts, .github/scripts/i18n/translate-i18n.ts	A 40,000-character threshold routes larger non-Qwen whole-file sources through translateBlockContent. Shorter sources still use translateWithLLM, and the Qwen-MT branch is unchanged.

Changelog date localization

Layer / File(s)	Summary
Spanish changelog dates .github/scripts/i18n/chunked-translate.ts, .github/scripts/i18n/chunked-translate.test.ts	The formatter adds Spanish month names and formats dates as day, month, and year separated by “de”. Tests cover Spanish, English, Chinese, Korean, and sync status.

Translated Tabs validation

Layer / File(s)	Summary
Tabs tag count validation .github/scripts/i18n/chunked-translate.ts, .github/scripts/i18n/chunked-translate.test.ts	Validation now requires translated opening and closing <Tabs> tag counts to match the English block. Tests cover an extra closing tag and a balanced block.

Merge Risk: Low · up to 8e20c

Oversized translated pages can occasionally have a heading glued to the preceding line when a piece reports mismatches. This is a bounded formatting defect that is easy to fix by preserving the newline between pieces. It is mergeable with owner awareness.

Ensure oversized whole files are split.

If max_block_chars is at least the file length, this path still sends the whole file in one call. The response can hit the token limit and fail validation, leaving the translation outdated. Ensure this path splits the file even with a larger configured limit.

Add a test for whole-file translation routing.

A routing regression could send an oversized non-Qwen page in one API call without failing the current tests. Add a mocked translation test at 40,000 and 40,001 characters, and cover the Qwen exception.

Minor · Keep the newline between translated pieces when a piece reports… · chunked-translate.ts:47

.github/scripts/i18n/chunked-translate.ts:47
Minor · Data Integrity & Integration · Quick win

Keep the newline between translated pieces when a piece reports mismatches.

When a piece reports === MISMATCHES ===, extractMismatches trims its trailing whitespace. translateBlockContent then joins the pieces with outs.join(""). If the next piece starts with an H3 heading, the heading can end up on the same line as the previous text. Whole-file validation does not check piece boundaries, so the malformed heading would pass.

Suggested fix

-    outs.push(result.content);
+    const content = result.content;
+    outs.push(
+      i < enPieces.length - 1 && !content.endsWith("\n") ? `${content}\n` : content
+    );

Update piece accumulation in translateBlockContent so a piece whose trailing
whitespace was removed by extractMismatches still has a newline before the next
piece is joined, unless it already ends with one; preserve the existing
final-piece behavior so following H3 headings remain on separate lines.
