docs(blog): add bilingual TypeScript 2.0 history and core statistics

[loopx-agent]

Goal And Result

Add a complete English/Chinese engineering retrospective for the LoopX2.0 TypeScript control-plane refactor. It follows the August15 RFC, Effect Program cutover, complete-transaction pivot, overlapping authority/store and SQLite work, Song's Semantics contributions, real caller counterexamples and October retirement. The final cleanup PR is presented as one closing slice.

The article includes whole-period statistics restricted to loopx/control_plane/**:1,144 mainline landings,1,121 associated merged PRs, source inventory/churn, weekly cadence and collaboration measures. Nine shared SVGs and downloadable public-safe CSV/JSON inventories make the evidence inspectable. Two locale indexes link the article after the existing first entry. Both articles remain fully static: a desktop contents list and native mobile details need no initialization script. Source pins and limitations distinguish engineering activity from migration completion, productivity or benchmark gains.

Author And Accepted Scope

Written by: model_agent — OpenAI Codex, GPT-6 family.

Specification: maintainer-requested bilingual2.0 engineering retrospective, using the TypeScript migration and Semantics RFCs and merged history pinned to 488e4438e0e51eca023ac3f5e690603120851b0c.

Criterion	Disposition	Evidence
Explain the full migration history and design changes	implemented	Both twelve-section articles link original RFC/PR evidence.
Attribute new maintainer Song's concrete Semantics work	implemented	Introduction, technical section and contributor table link his contributions.
Include reproducible core-directory statistics	implemented	Fixed range, methods, caveats, weekly charts and deduplicated public inventories.
Integrate both languages into the existing editorial site	implemented	Canonicals, hreflang, language navigation, shared article-local assets and locale index entries.

Complete within this publication-proposal scope. The copy is written for the2.0 release; actual merge, deployment and release timing remain maintainer decisions. No runtime, schema, scoring, permissions, scheduler or provider behavior changes. A related refactor was unnecessary; existing editorial styles are reused and additional layout is local to this article.

Validation

Tested revision: 1613d9e848d771f3f1709335edb4b0f38d79f4e2. Run state: finished. Inputs: public repository history and public-fixture editorial data.

Check	Result	Evidence / limitation
Full exported frontstage bundle	passed	npm run smoke:frontstage-share-bundle --prefix apps/presentation/dashboard; actual site/dashboard export, static bilingual pages, hosting-base links, public boundary and case restoration.
Production build	passed	npm run build --prefix apps/presentation/site (TypeScript and Vite client/SSR build).
SEO publication	passed	npm run smoke:seo --prefix apps/presentation/site;24 canonical sitemap targets, metadata and assets.
Static article/link checks	passed	One H1,12 sections and6 figures per language; local article/CSS/image/download/language targets exist in the build; approved prose unchanged except asset relocation. Existing MkDocs navigation is assembled separately by Pages.
Statistics reconciliation	passed	1,121 unique PR rows,1,144 mainline rows; review/comment sums and previously validated endpoint/gross-net inventories agree.
Public/private and whitespace	passed	All20 candidate paths checked; no credentials, local paths, private state or raw runtime traces; git diff --check passes. CSV records and SVG geometry/text preserved after whitespace normalization.
Responsive content preview	passed before integration	Both languages were inspected at1440px and390px; charts loaded, no page-wide overflow.
Final integrated browser readback	passed	English/Chinese at1440px and390px render with JavaScript disabled and zero article scripts; all6 figures load, no page-wide overflow; native mobile details toggle and language switching work.
Runtime / benchmark suites	not applicable	Static editorial additions only; no capability or performance claim is newly qualified.

Visual Evidence

UI impact: changed — new editorial pages; shared chrome unchanged. Before: N/A for the new article. The locale-index heading, routes and first listing remain byte-for-byte unchanged. After: English article, 中文全文.

The owner reviewed the full current content preview before author submission. One title anchors the viewport; source-bound tables and diagrams earn their space by explaining implementation choices. Narrow screens have scrollable tables/figures and a collapsed contents list. Screenshots below contain only public editorial content, with no browser chrome or account state.

Boundaries

• Public-safe editorial files and derived public statistics only; no private operational state or raw traces.
• No benchmark execution, scoring or runtime change.
• Scope is limited to this bilingual article, its index entries and shared assets.
• Author/committer identity is LoopX Agent; every commit includes DCO sign-off.
• Merge and publication remain separate from this PR.
