        "architecture": "Rust syntax-aware structural diff with tree-sitter parser integrations, delimiter/list atoms, comment/string-aware matching, CLI behavior tests, sample fixtures, CR-stripping input normalization, binary content detection and override globs, Git external-diff metadata, check-only/exit-code command status, list-languages command output, guarded unstable JSON display mode, and text/JSON/side-by-side/inline display output. The PHP lane adds WordPress-oriented escaped HTML rendering on top of mapped token, word, syntax-list, PHP/Hack signature, Python indentation/trailing-comma, oversized single-line display, side-by-side context-window/novel-color and ANSI syntax-highlight on/off semantics, parser-specific tag, Rust lifetime label-as-type and function.macro keyword-style highlighting, PHP/Hack superglobal variable.builtin highlighting, Emacs Lisp special-form and constant keyword-style highlighting, Python constructor/decorator capture highlighting, Python keyword/constant/variable.builtin/builtin-function and annotation-only builtin type-name highlight boundaries, Ruby keyword/constant/operator/constructor highlight boundaries, Ruby def/do/class/module block delimiter syntax-list paths, CSS at-keyword, JavaScript builtin variable capture highlighting including this/super, and keyword-ish boolean/constant/operator highlighting with attribute/property normal-boundary handling, unified inline header/context/syntax-highlight output, Git rename/mode metadata, check-only command status, list-languages status/catalog output, language override environment aggregation, display option environment aggregation including guarded DFT_UNSTABLE JSON command output, display-control environment aggregation for background/syntax-highlight/sort-paths, inline binary status output, binary override glob precedence, binary override environment aggregation, resource limit environment aggregation, guarded JSON directory print-unchanged/skip-unchanged command routing, and TOML table/key, inline-table, and array-table syntax-list output. The PHP lane also maps Lua keyword and builtin constant display promotion for build-helper scripts without promoting ordinary library calls. The PHP lane also maps SQL keyword/operator and builtin type display promotion from tree-sitter-sequel for WordPress schema review while leaving SQL boolean and field/function captures normal. The PHP lane also maps Bash keyword/operator and option-flag display promotion from tree-sitter-bash for WordPress deploy-script review while leaving command names and variable/property captures normal. The PHP lane also maps Java keyword/operator/type display promotion for WordPress build-helper review while leaving method, variable, and field/property captures normal."

in place, report `save` re-export source path changes, preserve block metadata JSON import attributes during `assert` to `with` modernization, report namespace re-export aliases plus type export-star source moves, and report dynamic `import()` metadata option changes under `$ts.import.dynamic.attributes[...]`, keep TSX `PanelBody` control changes focused while exposing inserted `&&`, `true`, and `false` as keyword-style spans and without rendering retained `TextControl` tags, hide TSX whitespace-only spacer expression churn in editor controls while preserving retained accessibility copy, keep reordered inner selectors stable inside block-style @media/@supports containers while reporting declaration changes, render single HTML `<style>` block CSS changes through `$html.style.css` sub-language paths and multiple attributed style blocks through indexed `$html.style[n].css[...]` paths, render single HTML `<script>` block JavaScript state changes through `$html.script.js.call[...]` paths and multiple attributed module scripts through indexed `$html.script[n].js.call[...]` paths without duplicate raw `$[...]` churn, report standalone view-script `if (window.wp)` wrappers plus action-array insertions under `$js.block[...]` and `$js.array[...]`, render generated block asset manifests with bounded side-by-side rows so inserted `view.js` asset entries and version changes stay readable even when the manifest is one physical line, keep generated C++ plugin build artifact fallback line-oriented without emitting retained generated rows, keep minified multibyte asset-map rows bounded when Japanese labels and package emoji are present, fall back to escaped line-oriented `$text.line[...]` changes and `Text (... exceeded DFT_PARSE_ERROR_LIMIT)` JSON labels for partial block editor JavaScript with unclosed object literals, fall back to escaped `$text.line[...]` changes and `Text (... exceeded DFT_BYTE_LIMIT)` JSON labels for oversized PHP render metadata and generated C++ build artifacts, fall back to escaped `$text.line[...]` changes and `Text (exceeded DFT_GRAPH_LIMIT)` JSON labels for large block variation JavaScript diffs, keep retained `wp.hooks.addAction`/`addFilter` registrations aligned by hook name when new callbacks are inserted, decode UTF-16 WXR bytes before JSON display so `_old_builder`, `_wp_page_template`, and `_thumbnail_id` postmeta changes render as XML text chunks instead of binary, decode legacy Windows-1252/Latin-1 plugin readme bytes so `m\u00fcller`, `L\u00f6st`, and `Bl\u00f6cke` remain readable while `alte` to `moderne` copy changes render as text chunks, decode slightly invalid UTF-8 WXR bytes with replacement characters before Windows-1252 fallback so `Legacy` to `Modern` title changes and `_wp_page_template` metadata remain XML review chunks, emit escaped HTML for plugin readme.txt, inline style/script, multi-inline asset, hook-registration, Python migration guards, Python nested migration guards, Python trailing-comma migration scripts, block-style, nested at-rule, template-wrapper, theme.json, block.json, TOML plugin config, block-markup, WXR XML, theme-variation, CSS/SCSS, TypeScript props, TypeScript module imports/exports, TSX edit controls, block view scripts, syntax-error fallback, byte-limit fallback, graph-limit fallback, and block allow-list review UIs, emit machine-readable JSON display chunks for plugin directory comparisons, guarded JSON command review of block.json, translated i18n block metadata with multibyte prefixes, TypeScript dynamic block metadata imports, Python migration decorator review, no-final-newline migration import logs, JavaScript browser-global display with this/super keyword spans, JavaScript parse fallback, PHP byte-limit fallback, generated C++ byte-limit fallback, graph-limit fallback, legacy encoded plugin readme review, slightly invalid WXR export review, and GitHub Actions workflow review pipelines, report `legacy`/`modern` copy changes inside block description strings as word spans, keep multibyte translated block copy byte spans valid after Japanese text, keep multiline PHP render doc-comment copy changes comment-highlighted for migration review, keep WP-CLI command changes and GitHub Actions expression replacements inside YAML `run: |` blocks string-highlighted, and render GitHub Actions workflow step insertions/deletions as nested YAML block-sequence changes.",
