-## Supported platforms
-
-BusyMark is currently developed and tested for Linux desktop, especially GNOME
-and Ubuntu-style GTK environments.
-
-## Supported files and projects
-
-BusyMark can open Markdown files such as `.md` and `.markdown`.
-
-BusyMark opens Writerside help modules whose root contains `writerside.cfg` or
-the equivalent older `project.ihp` file. Writerside support includes documented
-configuration locations for topics, images, variables, categories, instances,
-snippets, build configuration, API specifications, instance groups, and selected
-settings metadata. Topic support includes Markdown topics, XML `.topic` files,
-TOC registration, instance-specific topic titles, and custom web file names.
-Instance support includes local selection and icon colors, version/web-path and
-build settings, Markdown import, status, ID refactoring, instance groups,
-conditional and reusable TOC sections, and cross-instance topic references.
-See [Writerside instances](docs/writerside-instances.md) for behavior, safety
-rules, an openable example, and the authoritative JetBrains references.
-Writerside `<video>` elements are recognized in Markdown and XML topics, with
-local preview images plus HTTPS YouTube and Vimeo sources. See
-[Writerside videos](docs/videos.md) for syntax and preview/export behavior.
-Writerside tip, note, warning, and quote blocks render as native document
-callouts and can be inserted from the WYSIWYG toolbar. See
-[Writerside admonitions](docs/admonitions.md) for supported syntax.
-Writerside chapters, procedures, code blocks, and definition lists support
-documented collapsed and expanded states in Preview and WYSIWYG views. See
-[Writerside collapsible elements](docs/collapsible-elements.md) for syntax and
-the ordinary-Markdown boundary.
-
-Folder workspaces show all files and directories, including hidden project
-files such as `.gitignore`. Unsupported and binary files remain visible but are
-disabled in the text editor. Version-control metadata directories such as
-`.git` are excluded, and traversal remains bounded for safety.
-
-## PDF export
-
-Use **Main menu → Export as PDF** or <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>E</kbd>
-to export either the active Markdown document or the opened Writerside module.
-Markdown export uses the current editor contents, including unsaved changes,
-and offers A4 or Letter paper, portrait or landscape orientation, three margin
-sizes, and optional page numbers.
-
-Markdown PDF generation is local and offline. BusyMark bundles the pinned Typst
-compiler; users do not install or configure a separate program. Local PNG,
-JPEG, GIF, and safe SVG images are included. Remote images are deliberately not
-downloaded during export and are represented by their alternative text.
-
-Inline and display equations use the same bundled MathJax semantics in preview
-and PDF export. Safe generated equations remain self-contained vector SVG, with
-inline baseline metrics carried into Typst. See [mathematical expressions](docs/math.md)
-for supported Markdown and Writerside forms, the scientific TeX package profile,
-editing behavior, and offline security boundaries.
-
-Mermaid and PlantUML fences are exported as vector diagrams. D2 uses normalized
-SVG where possible and a local high-resolution raster fallback for browser-only
-labels. OpenAPI fences become static, selectable API reference content. Failed
-visualizations fall back to their original source and produce an export warning.
-
-See [offline visualizations](docs/visualizations.md) for supported fences,
-security policy, pinned engines, architecture, and verification. Working
-examples are in [demo/visualizations.md](demo/visualizations.md),
-[demo/openapi-local-reference.md](demo/openapi-local-reference.md), and
-[demo/plantuml-conformance.md](demo/plantuml-conformance.md).
-
-Writerside PDF export builds one selected output instance with BusyMark's
-bundled native Typst, MathJax, and diagram pipeline. It follows the resolved
-instance TOC and supports Writerside Markdown and `.topic` XML without Docker,
-a Writerside installation, a daemon, or a network connection. See
-[Writerside PDF export](docs/writerside-pdf-export.md) for supported layout
-options, security boundaries, and native-export scope. An exportable example is
-included in [demo/writerside-instances](demo/writerside-instances).
+## Markdown and Writerside
 
-## AI editing
+BusyMark opens Markdown files using `.md` and `.markdown` extensions and can work with ordinary documentation folders.
 
-BusyMark's optional AI editing is disabled by default and supports loopback
-Ollama, OpenAI, and Google Gemini. In Source and Editor views, select text and
-choose **Refine with AI** from its context menu, or press **Ctrl+G**. The user
-then writes the instruction and independently chooses what may change and what
-document context may be shared. Staged-diff commit-message drafting is
-available separately in Git Changes. BusyMark discloses the exact context,
-streams into a temporary proposal, reparses and validates the complete
-candidate Markdown document, shows a unified diff, and never applies a proposal
-without confirmation. Cloud
-keys are stored in the operating-system credential service and cloud use
-requires explicit consent; provider routing never crosses provider boundaries.
+Writerside-compatible projects are recognized through `writerside.cfg` and the older `project.ihp` format. BusyMark supports Markdown and XML topics, Writerside instances, tables of contents, reusable content, project configuration, and other commonly used Writerside documentation features.
 
-See [AI editing](docs/local-ai.md) for configuration, privacy and security
-boundaries, model routing, release qualification, and authoritative protocol
-references. An interactive exercise is available in
-[demo/ai-editing.md](demo/ai-editing.md).

-2. Run the application:
+BusyMark renders Mermaid, PlantUML, D2, and fenced OpenAPI content locally. Mathematical expressions are rendered with the bundled MathJax environment.
 
-```bash
-flutter doctor
-flutter pub get
-flutter run -d linux
-```
+See:
 
-Open a file or folder from the command line:
+* [Offline visualizations](docs/visualizations.md)
+* [Mathematical expressions](docs/math.md)
 
-```bash

-flutter run -d linux -- /path/to/docs
-```
+## Export
 
-## Feedback API
-
-The **Main menu → Report an issue** form
-submits JSON to `https://busystack.org/api/feedback`. BusyMark sends no private
-credentials or other API secrets; storage is handled by BusyStack.org.
-
-Every request contains a newly generated submission UUID, `app: "busymark"`,
-the application version and build number read from the current package's
-generated build metadata (including Flutter build overrides),
-`platform: "linux"`, the selected category, subject, detailed message, and the
-optional reply email. The optional `technicalDetails` object is included after
-user explicitly selects the checkbox. It contains exactly the Linux
-operating-system version and the BusyMark application locale; logs, files,
-document content, paths, account data, tokens, screenshots, and attachments are
-never added.
-
-```json
-{
-  "submissionId": "b3f44f5f-dae4-4c6e-bf56-657f35f3450a",
-  "app": "busymark",
-  "appVersion": "0.2.2",
-  "buildNumber": "0",
-  "platform": "linux",
-  "category": "problem",
-  "subject": "Example subject",
-  "message": "Detailed feedback message",
-  "replyEmail": null,
-  "technicalDetails": {
-    "osVersion": "Linux version string",
-    "locale": "en"
-  }
-}
-```
+BusyMark can export the current Markdown document or a Writerside instance to PDF and portable offline HTML.
 
-The endpoint returns HTTP 201 and `{"id":"<server reference ID>"}` after it
-accepts a report. Validation failures, connection failures, timeouts, rate
-limits, and server failures are shown without clearing the entered form.
+PDF export supports configurable paper size, orientation, margins, typography, headers and footers, page numbering, table of contents, and heading numbering.
 
-For local development, override only the endpoint at build time. For example,
-when the BusyStack.org backend is listening on port 8090:
+See:
 
-```bash
-flutter run -d linux \
-  --dart-define=BUSYSTACK_FEEDBACK_ENDPOINT=http://127.0.0.1:8090/api/feedback
-```
+* [PDF export settings](docs/pdf-export.md)
+* [Writerside PDF export](docs/writerside-pdf-export.md)
+* [HTML export](docs/html-export.md)
+
+## AI editing
 
-Production builds use the HTTPS endpoint by default. No credential belongs in
-the Dart define or in the desktop application.
+AI-assisted editing is optional and disabled by default.
 
-## Test
+BusyMark supports Ollama, OpenAI, and Google Gemini. Proposed edits are presented for review before changes are applied.
+
+See [AI editing](docs/local-ai.md) for configuration, privacy, provider behavior, and security information.
+
+## Installation
+
+Install BusyMark from the Snap Store:
 
 ```bash
-flutter analyze
-flutter test
+sudo snap install busymark --beta
 ```
 
-## Localization
-
-BusyMark has ARB localization files for:
-
-- Arabic (ar)
-- Dutch (nl)
-- English (en)
-- Estonian (et)
-- French (fr)
-- German (de)
-- Hindi (hi)
-- Indonesian (id)
-- Italian (it)
-- Japanese (ja)
-- Korean (ko)
-- Norwegian Bokmål (nb)
-- Persian (fa)
-- Polish (pl)
-- Portuguese (pt)
-- Russian (ru)
-- Simplified Chinese (zh-CN)
-- Spanish (es)
-- Turkish (tr)
-- Ukrainian (uk)
-- Vietnamese (vi)
-
-English in `lib/l10n/app_en.arb` is the source of truth for app strings.
-
-Target ARB files are audited for catalog parity, placeholders, plurals, and
-terminology.
-
-When changing user-facing text, update `app_en.arb`, keep every target ARB in
-sync, then run:
+The Snap uses strict confinement. See [Snap confinement notes](docs/snap-confinement.md) for details about filesystem and Git integration.
+
+## Run from source
+
+BusyMark currently uses Flutter 3.47.0.
+
+Install the required Linux development packages:
 
 ```bash
-flutter gen-l10n
-flutter analyze
-flutter test
+sudo apt-get install \
+  curl \
+  libhandy-1-dev \
+  xz-utils \
+  libwebkit2gtk-4.1-dev \
+  fonts-noto-core \
+  fonts-noto-mono
 ```
 
-Linux `.desktop` and AppStream metadata are localized in the repository. Snap
-Store listing translations are managed outside `snap/snapcraft.yaml`.
+Node.js 22 or newer with npm is also required when building the bundled web components.
 
-The Snap uses strict confinement and bundles Git and OpenSSH. If Git cannot
-find an author identity while committing, BusyMark opens a native form, saves
-the chosen repository or BusyMark-wide identity, and retries the commit. Install
-it with:
+Prepare and run the application:
 
 ```bash
-sudo snap install busymark
+flutter doctor
+flutter pub get
+flutter run -d linux
 ```
 
-The [Snap confinement notes](docs/snap-confinement.md) document supported
-interfaces and the limits of host Git integration.
+A Markdown file or documentation folder can be opened directly from the command line:
 
-## Build Linux Locally
+```bash
+flutter run -d linux
+```
+
+## Build
 
-Source builds require the libhandy and WebKitGTK 4.1 development headers,
-`curl`, `xz-utils`, and Node.js 22 or newer with npm. Node.js is used only to
-assemble the checksum-pinned web bundle. Packaged users receive every runtime
-component with BusyMark and do not install development packages, Node.js, Java,
-or Chromium.
+Build the Linux desktop application with:
 
 ```bash
-sudo apt-get install curl libhandy-1-dev xz-utils libwebkit2gtk-4.1-dev
-# Install Node.js 22 or newer from https://nodejs.org/en/download
-node --version
-npm --version
 flutter build linux
 ```
 
-The Linux build downloads the matching x86_64 or ARM64 Typst 0.15.1 binary, the
-Linux amd64 D2 0.7.1 release, and exact JavaScript packages, then verifies the
-pinned artifacts before bundling them. D2 visualization is currently packaged
-only for amd64. To reuse already downloaded official Typst and D2 archives,
-point the build at them:
+The build assembles the runtime components required by BusyMark. Packaged users do not need separate Typst, Java, Node.js, or Chromium installations.
+
+## Test
 
 ```bash
-BUSYMARK_TYPST_ARCHIVE=/path/to/typst-x86_64-unknown-linux-musl.tar.xz \
-BUSYMARK_D2_ARCHIVE=/path/to/d2-v0.7.1-linux-amd64.tar.gz \
-  flutter build linux
+flutter analyze
+flutter test
 ```
 
-A clean source build still assembles the checksum-pinned JavaScript packages.
-The resulting BusyMark application is self-contained and performs no runtime
-downloads for visualization.
-
-The Linux desktop file uses the application id `io.busystack.busymark` and
-installs the app icon from `assets/branding/busymark_logo.svg`.
-
 ## Contributing
 
-Issues and small focused pull requests are welcome. Please keep changes aligned
-with the current beta scope: local editing, Linux desktop quality, safe file
-handling, and clear user-facing behavior.
+Issues and focused pull requests are welcome.
+
+Changes should remain consistent with BusyMark's current scope as a desktop Markdown and Writerside documentation editor.

-audience: documentation-engineering
----

-# BusyMark AI editing release qualification
-
-Use this non-sensitive document to qualify an exact provider and model before a
-release. In **Settings → AI**, configure Local Ollama, OpenAI, or Google Gemini,
-run **Test connection**, and record the provider/model shown in each proposal.
-For a cloud provider, confirm the disclosure before sending this content. Work
-in **Source** view and review every diff before applying it.
-
-## Rewrite for clarity
-
-Select the following paragraph and choose **Rewrite**:
-
-The release process is something that has a number of steps which need to be
-performed by the documentation owner, and those steps should be carried out in
-the order in which they are described because doing them in another order can
-cause the published documentation to become inconsistent with the application.
-
-Expected quality: concise professional prose, unchanged meaning, and no added
-facts.
-
-## Shorten without losing requirements
-
-Select the following paragraph and choose **Shorten**:
-
-Before publishing the operator guide, the release engineer must validate all
-internal links, build the English and German editions, retain the generated
-reports for ninety days, and obtain approval from both the documentation lead
-and the security reviewer. Publication must not begin until both approvals are
-recorded in the release ticket.
-
-Expected quality: every language, retention period, approval, and ordering
-constraint remains present.
-
-## Proofread
-
-Select the following paragraph and choose **Proofread**:
-
-Each administrator configure the service before users signs in. The settings
-is stored locally, and they must be reviewed when the server are upgraded.
-
-Expected quality: grammar and agreement are corrected without changing the
-operational requirement.
-
-## Change tone
-
-Select the following paragraph, choose **Change tone**, and enter
-`neutral technical documentation`:
-
-Just flip this switch and you are good to go. If the network is acting weird,
-give the service a minute and smash Retry again.
-
-Expected quality: the instructions become professional without inventing a
-different control, wait time, or recovery procedure.
-
-## Translate
-
-Select the following paragraph, choose **Translate**, and enter a target
-language such as `German`:
-
-The maintenance window begins at 22:00 UTC. Save active work before the window
-starts because the documentation service will be unavailable for approximately
-fifteen minutes.
-
-Expected quality: `22:00 UTC` and the fifteen-minute duration remain exact.
-
-## Summarize
-
-Select the following three paragraphs and choose **Summarize**:
-
-The migration begins with a read-only inventory of every published space. The
-inventory records the owning team, current release, custom domain, and number
-of active readers. It does not copy document content.
-
-After the owners approve the inventory, the migration tool creates the target
-spaces and copies one release at a time. Each copied release is validated
-before its target space becomes visible.
-
-The old service remains available for seven days after validation. During that
-period it is read-only, and all new changes must be made in the target service.
-The operations team removes the old service only after the rollback period.
-
-Expected quality: inventory, approval, per-release validation, and the
-seven-day rollback period all survive in a concise summary. Also run Summarize
-with no selection to qualify whole-document context disclosure and insertion.
-
-## Draft from notes
-
-Place the cursor after these notes, choose **Draft**, and enter
-`Write a concise deployment prerequisites section`:
-
-- Ubuntu 24.04 hosts
-- outbound HTTPS to the approved package mirror
-- 8 GB RAM minimum; 16 GB recommended
-- a non-interactive service account
-- 20 GB free disk space before upgrade
-
-Expected quality: valid Markdown using only the supplied requirements.
-
-## Fenced-code assistance
-
-Place the cursor inside this fence and choose **Explain code block**. The
-proposal should insert a concise explanation after the fence without changing
-the code.
-
-```dart
-Iterable<String> releaseTags(Iterable<String> tags) sync* {
-  for (final tag in tags) {
-    if (tag.startsWith('release/')) yield tag.substring(8);
-  }
-}
-```
-
-Next choose **Improve code block**. BusyMark must accept only a proposal that
-replaces exactly this complete fence while preserving the `dart` language
-identifier. Review behavior changes rather than assuming generated code is
-correct.
-
-## Protected Markdown regression fixture {#protected-fixture}
-
-Select only the prose in the next paragraph and choose **Rewrite**. BusyMark may
-change the prose but must reject a result that swaps or alters either link:
-
-Read the [operator guide][operations] before opening the
-[release checklist](https://docs.example.test/releases/checklist).
-
-Select the rest of this section and choose **Rewrite**. BusyMark must reject a
-proposal that changes the reference/footnote identifiers, URL associations,
-autolink, table structure, heading ID, Writerside element, or code:

-## Stale, cancellation, and request isolation
-
-Start an action, edit the document before generation finishes, and verify that
-**Apply proposal** remains disabled. Start a second action on the same target
-and verify that the older request is cancelled. Cancel a streaming proposal and
-verify that no partial text reaches the editor.
-
-## Git commit-message draft
-
-In a disposable Git repository, stage a small documentation edit while leaving
-a different edit unstaged. In **Git → Changes**, choose **Draft with AI**.
-Verify that:
-
-- the disclosure identifies a staged Git diff;
-- the proposal describes only staged changes;
-- accepting it fills, but does not submit, the commit-message field;
-- the subject is at most 72 characters;
-- a body, when present, follows a blank line;
-- no file is staged, unstaged, or committed by the AI action.
-
-## Deterministic checks
-
-Choose **Generate/update table of contents** twice. Verify that one
-marker-delimited TOC is generated and the second run updates it rather than
-duplicating it. Then introduce a skipped heading level, an empty link, and an
-empty table header to verify that BusyMark reports deterministic accessibility
-diagnostics without making an AI request.

+# Editor clipboard fix
+
+Status: implemented for the Linux desktop host.
+
+Editor copy previously published only plain text. Formatting stayed in a private
+cache inside one Editor widget, so a fresh Editor or another application could
+not retrieve it. Copy now publishes three representations in one GTK clipboard
+operation, and ordinary paste uses the richest supported representation.
+
+| Representation | Purpose |
+| --- | --- |
+| `application/x-busymark-fragment+json` | Preserve BusyMark structure, inline formatting, task states, tables, and Writerside content between instances. |
+| `text/html` | Preserve headings, emphasis, links, lists, tables, and code in compatible external applications. Tasks have visible checked/unchecked symbols. |
+| Standard GTK text targets | Support text-only destinations and Paste without formatting. |
+
+## Implementation
+
+- `rich_clipboard_service.dart` serializes competing writes and reads the system
+  clipboard without a private formatting cache. A native write publishes all
+  formats together; it is never followed by a plain write that would erase them.
+- `rich_clipboard_host.cc` owns immutable payload bytes independently of the
+  originating widget. Reads are asynchronous and reject data from an owner that
+  changes during the read. Transfers are limited to 16 MiB. The host advertises
+  all formats for clipboard-manager storage using
+  [`gtk_clipboard_set_can_store`](https://docs.gtk.org/gtk3/method.Clipboard.set_can_store.html).
+  GTK's existing application shutdown performs the storage request.
+- `wysiwyg_clipboard_fragment.dart` uses a versioned, bounded, validated JSON
+  schema. Block IDs are regenerated during insertion. Relative links are rebased
+  and resolved local media paths are carried between documents/projects.
+- `wysiwyg_clipboard_html.dart` exports semantic HTML directly from the copied
+  blocks. On import it normalizes supported CSS emphasis and checkbox state,
+  strips executable markup and unsafe URLs, and uses the existing HTML adapter.
+  It does not change the document HTML policy or write publication assets.
+- Editor copy snapshots the selection before asynchronous work. Cut deletes only
+  after a successful write. Paste and cut recheck the file, document generation,
+  active block/cell, and selection before changing the document. Nested children
+  are copied once; complete blockquotes retain their container.
+- Insertion preserves inline nodes, including image references, and supports
+  partial selections and one-step undo/redo. Table cells retain supported inline
+  styles while block boundaries become spaces. Cells displayed as math source
+  retain their existing text insertion behavior.
+
+## Validation
+
+- 238 editor/model regression tests pass, including fresh Editor instances,
+  same-Editor cut/paste, partial selections, nested lists, blockquotes, tasks,
+  tables, code, Writerside, images, RTL, math, undo/redo, malformed fragments,
+  serialized writes, failed cut, delayed paste, and a later plain-text copy.
+- A document-wide selection has its own right-click menu for Cut, Copy, Paste,
+  Select all, and Refine with AI when available. The selected blocks stay active
+  while the menu opens, including when the pointer is over a table cell.
+- Both reported files, `issues.md` and `writerside-support.md`, passed a read-only
+  codec and insertion probe. Heading, task, table, blockquote, and code content
+  survived; exported HTML also imported successfully.
+- Separate compiled BusyMark processes exchanged JSON, HTML, and plain text on
+  isolated X11 and headless GNOME Wayland displays. A subsequent Flutter plain
+  copy cleared the rich formats.
+- LibreOffice Writer pasted a Heading 1 paragraph, bold text, and visible checked
+  and unchecked task states from the compiled Linux implementation.
+
+The native probe entrypoint is `tools/clipboard_smoke.dart`. Build it with
+`flutter build linux --debug -t tools/clipboard_smoke.dart`, then run `write`,
+`read`, or `plain` with the same temporary output directory on an isolated display.
+Keep `write` running until the reads complete; creating a `stop` file in that
+directory closes it. Rebuild with the default entrypoint afterward.
+
+## Interoperability limits
+
+Clipboard persistence after the source process exits depends on the desktop's
+clipboard manager and the formats it retains. That exit scenario remains a manual
+check. Source-widget disposal does not discard clipboard payloads. External
+applications choose which offered format to consume; plain-text applications
+will still paste plain text. Writerside-specific structures remain editable
+through the BusyMark format and use readable HTML fallbacks externally. Local
+media references point to existing files and do not bundle their bytes.
+
+Hosts without the Linux method channel currently fall back to plain text.

+# PDF and HTML export verification — September 5, 2026
+
+Validation used Flutter 3.47.0 on Linux, bundled Typst 0.15.1, the bundled Noto
+fonts, and BusyMark’s existing local math and visualization engines. User-facing
+settings are documented in [PDF export](pdf-export.md), [HTML export](html-export.md),
+and [Writerside PDF export](writerside-pdf-export.md).
+
+## Implementation areas
+
+- `lib/src/export/export_options.dart` supplies shared content options and one
+  validated, serializable option model per format. `app_settings.dart` persists
+  the last confirmed values through the existing settings store.
+- `export_options_editor.dart` supplies the reusable modal editors for Markdown
+  and Writerside. Existing PDF and HTML export UI entry points use those editors;
+  Writerside retains its workspace-specific instance and Save/Discard/Cancel flow.
+- `typst_payload_builder.dart`, `markdown_math_export.dart`, `typst_compiler.dart`,
+  and `assets/export/markdown.typ` carry PDF geometry, typography, native TOC,
+  numbering, accent, and running text through payload schema 2. The semantic
+  `markdown_export_mapper.dart` no longer sets PDF math metrics.
+- `html_document_writer.dart`, `html_export_styles.dart`, `html_export_assets.dart`,
+  and the HTML service/rich-content preparation apply themes, typography, semantic
+  TOCs, numbering, bounded custom CSS, and both resource packaging modes.
+  `export_metadata_mapper.dart` provides common resolved metadata.
+- Linux and Snap build configuration stages Noto Sans, Serif, Mono and available
+  Noto script fallbacks. Localization sources and generated output cover all new
+  settings. Focused model, widget, payload, native PDF, HTML, math and Writerside
+  tests sit beside the existing export tests.
+
+## Executed checks
+
+| Check | Result |
+| --- | --- |
+| Changed Dart sources formatted; `git diff --check`; Python browser script syntax | Passed |
+| Repository-wide `flutter analyze --no-pub` | Passed; no issues |
+| `flutter gen-l10n` and localization audit | Passed |
+| Full `flutter test --no-pub` with bundled Typst and D2 paths | **1,469 passed; no skips** |
+| Native PDF customization tests | Six profiles compiled; page geometry, embedded Noto families, body/code sizes, native outline entries/page references, heading numbering, running titles and counter placement verified |
+| Workspace refresh regression | Reproduced before the fix; all 63 controller tests pass after the fix |
+| `flutter build linux --release --no-pub` | Passed; final release bundle includes Noto fonts and licenses |
+| Release application smoke under Xvfb | Passed; MathJax 4.1.3, Mermaid, PlantUML, D2, static OpenAPI, default/custom PDFs and Markdown/Writerside HTML; zero HTML warnings |
+| Relocated browser verification | **46 passed** in Chrome 151.0.7922.137 and Firefox 154.0.1 |
+
+The new tests cover absent/malformed persisted settings, validation and geometry,
+all four dialogs’ reuse of remembered format options, dependent controls, Reset,
+cancellation, CSS validation and ordering, embedded and external assets, output
+bounds, existing-output preservation, metadata, TOC hierarchy/depth, numbering,
+custom math metrics, and unchanged Writerside resolution and publication order.
+Existing PDF, HTML, native menu, source-preservation and editor tests remain part
+of the complete suite.
+
+Full-suite verification exposed an existing filesystem-monitor race: a background
+refresh could invalidate a foreground Writerside operation. A controlled regression
+test reproduced that failure. Monitor refreshes now wait for active loading to
+finish, and stale/disposed refreshes stop before changing controller state.
+
+Historical note: at the time of this HTML-export verification, the base `pt`
+and `zh` catalogs were still partial while `pt_BR` and `zh_CN` were complete.
+That limitation has since been superseded: localization policy now requires
+both base and regional catalogs to contain the complete English message-key set.
+
+## Browser and output verification
+
+Browser checks open relocated Markdown and Writerside pages through both `file:`
+URLs and a local static HTTP server, with external networking unavailable. They
+verify image loading, CSP/style hashing, metadata, custom CSS overrides, typography,
+automatic light/dark preference, embedded resources, anchors, footnotes, navigation,
+keyboard focus, disclosure, overflow, script blocking and printing. Request
+observation recorded no unexpected external resources; local favicon 404 probes
+are not document dependencies. Representative screenshots were visually inspected.
+Print checks include disclosure bodies and every Writerside tab.
+
+Representative outputs generated by the release application:
+
+- `/tmp/busymark-custom-output/offline.html` and `offline.assets/`: default
+  Markdown output with Unicode headings, nested/task lists, tables, disclosure,
+  local SVG, inline/display math, three diagram engines, static API and footnotes.
+- `/tmp/busymark-custom-output/automatic-single.html`: automatic theme, embedded
+  resources, 20 px serif text, customized width/accent, numbered headings and CSS.
+- `/tmp/busymark-custom-output/dark-assets.html`: dark appearance with companion
+  resources using relative URLs.
+- `/tmp/busymark-custom-output/writerside/index.html`: default multipage instance
+  with includes, variables, all tabs, procedures, custom filenames, hidden topics
+  and work-in-progress status.
+- `/tmp/busymark-custom-output/writerside-embedded/index.html`: the same instance
+  with shared customization and embedded resources in each topic page.
+- `/tmp/busymark-custom-output/visualization-smoke.pdf`: default PDF rich content.
+- `/tmp/busymark-custom-output/customized.pdf`: 240 × 320 mm pages, independent
+  margins, 14 pt Noto Sans, 11 pt code, purple accent, numbered native TOC,
+  title headers/footers, right-aligned page numbers and first-page suppression.
+
+Native results are in `/tmp/busymark-custom-output/report.json`. Browser results,
+screenshots and printed PDFs are under `/tmp/busymark-custom-browser-final/`;
+`browser-report.json` identifies the separate relocated root. The source fixtures
+and renderer temporary directories were removed before opening relocated copies.
+These temporary artifact paths are not export dependencies and may be cleaned up.
+
+To reproduce with a release bundle and the browser-check dependencies installed:
+
+```sh
+BUSYMARK_RELEASE_SMOKE=1 xvfb-run -a build/linux/x64/release/bundle/busymark \
+  --visualization-release-smoke=/tmp/busymark-custom-output/report.json
+python3 tools/verify_html_export_browser.py /tmp/busymark-custom-output \
+  --output /tmp/busymark-custom-browser-final
+```
+
+Browser and print verification ran headlessly. Physical-printer output, assistive
+technology certification, and a complete Snap package build were not performed;
+the Linux bundle and its staged Noto fonts/licenses were verified. The existing
+HTML exporter has no client-side syntax highlighter, so this change retains its
+code rendering and supplies a theme-aware code palette without another dependency.

+# HTML export
+
+Choose **Main menu → Export as HTML…** or use the command palette. HTML has no
+default shortcut; **Ctrl+Shift+E** continues to export PDF.
+
+Markdown exports the active document’s current editor text, including unsaved
+and untitled content. Writerside first offers Save, Discard, or Cancel for
+project changes, then lets you choose a non-library instance and a dedicated
+output directory.
+
+## Export settings
+
+Markdown and Writerside share the same HTML settings, independently of your
+editor and preview theme:
+
+- **Content:** include a heading-based table of contents, choose a depth from
+  1–6, and number headings. The TOC links to the existing heading anchors.
+  Numbering changes the export only. The heading outline remains enabled by
+  default; heading numbering is off.
+- **Appearance:** light, dark, or automatic theme; serif or sans-serif body
+  text; a base size from 12–28 px; and an accent/link color. Automatic follows
+  the browser’s light/dark preference. Code uses the export’s theme without
+  requiring a browser highlighting library.
+- **Layout:** a maximum content width from 320–1920 px. Pages still adapt to
+  smaller screens; wide code blocks and tables scroll within the page.
+- **Output:** a single HTML file or HTML with an assets directory, plus an
+  optional custom stylesheet.
+
+Defaults are a light theme, 17 px sans-serif text, a maximum width of 918 px,
+blue links, an assets directory when needed, and no custom stylesheet.
+
+BusyMark remembers the last confirmed HTML settings globally, including across
+Markdown and Writerside exports. PDF settings are remembered separately.
+**Reset to defaults** restores the default values in the dialog. Cancelling
+the settings dialog leaves the remembered values unchanged.
+
+## Packaging
+
+**Single HTML file** embeds the local and generated resources needed by a
+Markdown document, so you can copy the `.html` file on its own. Remote resources
+are not downloaded or embedded.
+
+**HTML + assets directory** places images, media, downloads, and generated
+graphics in a companion `<name>.assets` directory using relative links. Keep
+the HTML file and that directory together when copying the export. A text-only
+document needs just the HTML file.
+
+Writerside always retains separate linked topic pages and an `index.html`
+entry point. With an assets directory, pages share `assets/`. In single-file
+mode, each topic page embeds its resources; copy the entire instance directory
+to preserve navigation. Hidden topics retain pages without navigation entries,
+and work-in-progress entries retain their status. Repeated TOC references share
+one page. Existing topic filenames and resolved instance order are preserved.
+
+Both modes work offline when opened directly in a browser or served by a static
+web server. No BusyMark installation, preview server, or original source folder
+is required to read them.
+
+## Custom CSS
+
+Select **Custom stylesheet…** to choose a local UTF-8 `.css` file of up to
+256 KiB. Its rules follow BusyMark’s generated stylesheet, allowing intentional
+overrides. **Remove custom stylesheet** returns to the built-in appearance.
+
+BusyMark reads CSS directly, without running a preprocessor. Imports, resource
+URLs, escaped CSS, HTML, and executable CSS are rejected. No remote fonts or
+other resources are fetched. A missing, oversized, or invalid stylesheet must
+be corrected or removed before exporting. Browser scripts and template code
+are not supported customization mechanisms.
+
+Custom CSS is optional. The generated document already has semantic headings,
+links, lists, tables, code, metadata, and accessible navigation. Built-in print
+styles hide navigation and expose disclosure bodies and every Writerside tab.
+Custom rules can override presentation, including print styling.
+
+## Resources and existing exports
+
+Supported local images, media, equations, diagrams, and static API documentation
+are prepared during export. Remote video remains a link. Missing or unsupported
+content produces an actionable diagnostic and readable fallback where possible.
+HTML does not automatically export other linked Markdown documents or crawl
+other Writerside instances.
+
+Choose the destination after confirming settings. BusyMark asks before replacing
+existing output. A Writerside destination can replace only an unmodified export
+created by BusyMark, protecting unrelated files. Cancellation and ordinary
+export failures preserve the previous output.
+
+The result offers **Open**, **Show in Folder**, and source-associated diagnostics.
+When replacing an HTML document with an assets directory, old resources may be
+retained so earlier copies of that HTML remain usable.

+# PDF export
+
+Choose **Main menu → Export as PDF…**, use the command palette, or press
+**Ctrl+Shift+E**. Markdown exports the active editor text, including unsaved and
+untitled documents. Writerside first offers Save, Discard, or Cancel for project
+changes, then lets you select a non-library instance.
+
+The export settings are independent of the editor and preview appearance.
+Markdown and Writerside offer the same PDF controls:
+
+- **Content:** include a table of contents, choose its heading depth from 1–6,
+  and number headings. Numbering does not modify your source. The table of
+  contents uses the document’s headings and page numbers.
+- **Page:** A4, US Letter, US Legal, or custom dimensions in millimetres;
+  portrait or landscape; narrow, normal, wide, or four independent custom
+  margins. Custom dimensions are 50–1200 mm. Margins must leave at least 20 mm
+  of content width and height.
+- **Typography:** serif or sans-serif body text, body size from 8–24 pt, and
+  code size from 6–20 pt. BusyMark includes Noto fonts for consistent PDF
+  typography. Heading sizes scale with the body size, and equations use the
+  selected typography and available page width.
+- **Header & Footer:** no text or the resolved document title in either area;
+  page numbers off, bottom left, bottom center, or bottom right; and whether
+  headers, footers, and page numbers appear on the first page.
+- **Appearance:** an accent/link color, chosen from the palette or entered as
+  `#RRGGBB`.
+
+After you confirm the settings, BusyMark remembers them globally for the next
+PDF export, including exports from other documents and Writerside modules.
+**Reset to defaults** restores the default values in the dialog. Cancel leaves
+your remembered settings unchanged. PDF and HTML remember separate settings.
+
+Defaults are A4 portrait, normal margins, 10.5 pt serif body text, 8.4 pt code,
+blue links, and centered page numbers on all pages. Generated TOC and heading
+numbering are off. Custom page dimensions describe the portrait geometry;
+landscape swaps the width and height.
+
+Choose the destination after confirming settings. BusyMark asks before
+replacing an existing file. Export can be cancelled, and a failed export keeps
+the previous PDF usable.
+
+## Offline content
+
+PDF export works locally with BusyMark’s included PDF, math, and diagram tools.
+It does not download remote images, fonts, or other resources. Supported local
+images, equations, diagrams, tables, links, and static API documentation remain
+part of the exported document. When supported content cannot be rendered,
+BusyMark reports a warning and keeps readable alternative text or source where
+possible.
+
+For instance ordering and Writerside content behavior, see
+[Writerside PDF export](writerside-pdf-export.md).

+# Writerside support
+
+BusyMark's semantic baseline is Writerside **2026.08.0328**, documented by
+JetBrains on September 1, 2026. Preview and native PDF export use the same
+`WritersideDocumentResolver` and `WritersideDocumentRenderer`.
+
+## Resolved content
+
+- Includes accept XML IDs and Markdown block IDs. A Markdown heading identifies
+  its chapter through the next heading of the same or higher level. Snippets
+  render at their declaration site in ordinary topics as well as at include sites.
+- Blank-line-delimited Markdown inside semantic containers retains formatting
+  and original source positions. Fenced code and CDATA remain literal.
+- Instance-conditioned globals, local scopes, snippet defaults and include
+  arguments resolve before rendering. Include arguments override defaults;
+  dependent variable values use the final scope. Escaped percentages and
+  `ignore-vars` remain supported.
+- Links resolve topic/element titles, separate anchors, summaries and selected
+  instance availability. Missing nullable targets render as text.
+- Code, diagrams and API samples share guarded source loading. Configured
+  directories and paths relative to the originating topic work through includes.
+  Referenced code supports line lists/ranges and language-aware symbol selection.
+  Symbol selection uses indentation or lexical declaration/delimiter matching;
+  unsupported languages, ambiguous declarations and invalid selections produce
+  source diagnostics rather than selecting arbitrary text.
+- Configured glossary terms, keymap actions and resources produce visible,
+  meaningful references. Resource links are checked again before opening.
+- Unsaved open dependency buffers participate in preview and reference indexing.
+
+## Presentation and export
+
+| Content | Preview | PDF |
+| --- | --- | --- |
+| Tabs | Selectable panels, synchronized `group`/`group-key`, arrow/Home/End/Tab navigation | Every panel, with its label |
+| Topic switchers | Separate topic-wide `switcher-key` selection | Every variant, with its label |
+| Tables | Default first-row headers; header styles, spans, widths, nested content, sticky headers and natural numeric sorting | Structural tables with spans, widths and nested content |
+| Shortcuts | Configured action combinations; selectable layouts | Labeled combinations for configured layouts |
+| Glossary | Term description tooltip | Term and description footnote |
+| Starting pages | Section/card/link groups, titles and descriptions; outside topic content suppressed | Same resolved sections and cards in reading order |
+| Summaries | Link/card/web metadata stays out of body text | Metadata stays out of body text |
+| API elements | Existing OpenAPI pipeline selects tags, operations, schemas and webhooks; inherited specification references, nested schemas and sample overrides | Same resolved reference and all sample panels |
+| Unsupported content | Visible source fallback and source-linked diagnostic | Visible fallback with a warning, or an explicit resolution failure |
+
+Native export resolves local topic links to unique PDF destinations, including
+non-heading IDs. Source references carry resolved text, while image/resource
+locations carry paths; asset rewriting therefore cannot turn a diagram reference
+into a rejected `file:` source. Export requires saved project changes, as before.
+
+OpenAPI schema depth controls inline expansion; this editor does not generate
+website pages for schema objects. File resources in a PDF remain local links,
+so a shared PDF does not bundle those downloadable files automatically.
+
+## Source assistance
+
+Source-editor menus and shortcuts provide **Go to Declaration** (`Ctrl+B`),
+**Find Usages** (`Alt+F7`) and **Rename** (`Shift+F6`). Identities include the
+module, topic file and symbol, with lexical scope for local variables. Find
+Usages searches all indexed topics, including those outside the selected
+instance. Rename verifies every source range and stages normal undoable edits in
+document tabs. Existing topic-file and instance operations remain available.
+
+Completion filters by syntactic context and prefix before limiting results.
+Attribute values use reference kinds and, for element IDs, the referenced topic.
+The authoring registry incorporates JetBrains' official topic XSD and documented
+release overlays such as sortable tables. Recognizing an element in this
+registry does not imply a semantic renderer: unsupported content is diagnosed.
+Build-profile validation accepts `<llms-txt>true</llms-txt>` and rejects the old
+`single-file` form.
+
+## Verification
+
+`test/src/writerside_*_test.dart` covers resolution, source preservation, file
+bounds, instance changes, widgets, editing and export. A native Typst integration
+test runs when the bundled compiler is present; otherwise it is explicitly skipped.
+API unit tests inject the existing platform parser interface; they do not claim
+to run that native parser.
+
+`test/fixtures/writerside/conformance_semantics.json` was extracted from the
+**2026.08.0328** official builder output. The fixture's builder report had 181
+passing checks with no warnings or errors. BusyMark tests compare paragraphs,
+quotes, shortcuts, tooltip descriptions, table cell structure and See also links
+against this snapshot. This is a comparison for that fixture, not a claim of
+complete website artifact parity.
+
+```bash
+flutter test --no-pub test/src/writerside*_test.dart \
+  test/src/source_autocomplete_test.dart test/src/source_editor_widget_test.dart \
+  test/src/workspace_controller_test.dart test/src/markdown_export_mapper_test.dart
+bash tools/validate_writerside_conformance.sh
+```
+
+The builder check uses temporary source copies and checks both the builder report
+and normalized semantic snapshot. Set `WRITERSIDE_CONFORMANCE_OUTPUT` to retain
+its generated artifacts. Schema extraction is reproducible with
+`python3 tools/generate_writerside_schema.py /path/to/topic.v2.xsd`; the generated
+file records the XSD URL and SHA-256. Format the result with `dart format`.
