Pushed in `be8f6a1` and `66d1511`. Summary of each:\\n\\n**Fixed**\\n- **XML 1.0-invalid control chars** (Gemini HIGH + Codex P2, `OOXMLPackageWriter.escape`): now filters disallowed scalars (NUL, vertical tab, etc.) before escaping, so raw `write(markdown:)` input — which skips `sanitizeUnicode` — can't produce non-well-formed `document.xml`/worksheet/slide parts.\\n- **Image lookup by basename** (Gemini, `WordprocessingMLExporter`): falls back to the source's last path component when it carries a path prefix.\\n- **Sheet-name grapheme clusters** (Gemini, `XLSXExporter`): rebuilds via `UnicodeScalarView` so emoji / multi-scalar clusters survive sanitization.\\n- **Pre-compiled emphasis regexes** (Gemini, `MarkdownInline`): the three matchers are compiled once instead of per recursive call.\\n- **Duplicate media parts** (Codex P2): repeated references to the same image now reuse a single media part + relationship (unique drawing ids), avoiding duplicate ZIP entries.\\n- **Alt text in DOCX drawings** (Codex P2): Markdown alt text is written to `wp:docPr/@descr`, which `WordConverter.imageAltText` reads first, so it round-trips instead of collapsing to the filename.\\n- **Escaped label delimiters** (Codex P2, `MarkdownInline`): the label scan skips backslash-escaped `\\\\]` and unescapes the recovered label.\\n- **Balanced parens in destinations** (Codex P2): bare link/image destinations match balanced parentheses, so `https://e.com/Foo_(bar)` isn't truncated.\\n- **Ordered-list restart** (Codex P2): each ordered list gets its own numbering instance with a `startOverride`, so Word restarts separate lists at 1 instead of continuing.\\n- **Image-only results render blank** (Codex P2, `PicoDocs.write`): image-only `ConverterResult`s now synthesize an inline `[alt](name)` reference per `.image` carrier so the bytes are actually embedded, keeping the \\\"image-only doc is valid output\\\" contract honest.\\n\\nAdded tests covering image-only export, balanced-paren links, and escaped label delimiters. The Swift 6 build error from the first push (a non-`Sendable` closure in the static regex table) is fixed in `66d1511` by keeping only the compiled regexes in static storage.\\n\\n---\\n_Generated by [Claude Code](https://claude.ai/code)_\",\"path\":null,\"side\":null,\"line\":null}{\"type\":\"pull_request_comment\",\"body\":\"Thanks for the detailed summary of the fixes, @ronaldmannak.

(file: /workspace/PicoDocs/.agents/skills/spm-build-analysis/SKILL.md)\n- swift-accessibility-skill: Apply platform accessibility best practices to SwiftUI, UIKit, and AppKit code. Essential companion to any SwiftUI, UIKit, or AppKit skill — always use together. Use whenever writing, editing, or reviewing ANY SwiftUI views, UIKit view controllers, AppKit views/window controllers, or platform UI — even when the user doesn't mention accessibility. Also use when the user mentions VoiceOver, Voice Control, Dynamic Type, Reduce Motion, screen reader, a11y, WCAG, accessibility audit, Nutrition Labels, accessibilityLabel, UIAccessibility, NSAccessibility, assistive technologies, or Switch Control. Not for server-side Swift, non-UI packages, or CLI tools.

Skill bodies live on disk at the listed paths.\n- Trigger rules: If the user names a skill (with `$SkillName` or plain text) OR the task clearly matches a skill's description shown above, you must use that skill for that turn. Multiple mentions mean use them all. Do not carry skills across turns unless re-mentioned.\n- Missing/blocked: If a named skill isn't in the list or the path can't be read, say so briefly and continue with the best fallback.\n- How to use a skill (progressive disclosure):\n 1) After deciding to use a skill, open its `SKILL.md`. Read only enough to follow the workflow.\n 2) When `SKILL.md` references relative paths (e.g., `scripts/foo.py`), resolve them relative to the skill directory listed above first, and only consider other paths if needed.\n 3) If `SKILL.md` points to extra folders such as `references/`, load only the specific files needed for the request; don't bulk-load everything.\n 4) If `scripts/` exist, prefer running or patching them instead of retyping large code blocks.\n 5) If `assets/` or templates exist, reuse them instead of recreating from scratch.\n- Coordination and sequencing:\n - If multiple skills apply, choose the minimal set that covers the request and state the order you'll use them.\n - Announce which skill(s) you're using and why (one short line). If you skip an obvious skill, say why.\n- Context hygiene:\n - Keep context small: summarize long sections instead of pasting them; only load extra files when needed.\n - Avoid deep reference-chasing: prefer opening only files directly linked from `SKILL.md` unless you're blocked.\n - When variants exist (frameworks, providers, domains), pick only the relevant reference file(s) and note that choice.\n- Safety and fallback: If a skill can't be applied cleanly (missing files, unclear instructions), state the issue, pick the next-best approach, and continue.\n","\nFilesystem sandboxing defines which files can be read or written. `sandbox_mode` is `danger-full-access`: No filesystem sandboxing - all commands are permitted.

Users can now serialize LLM Markdown output or structured document results into DOCX, XLSX, PPTX, and RTF files via `PicoDocsEngine.write(...)`. The implementation includes hand-rolled OOXML writers for DOCX/XLSX/PPTX (ensuring round-trip fidelity with the existing readers), platform-native exporters for RTF, and shared Markdown intermediate representations used by both renderers and exporters.\n\n## Key Changes\n\n- **Shared Markdown IR**: Extracted block-level (`MarkdownBlock`) and inline (`MarkdownInline`) parsing from `DocumentRenderer` into reusable enums (`MarkdownBlockParser`, `MarkdownInlineParser`). Both renderers and exporters now consume the same structured representation, ensuring consistency and simplifying future parser improvements.\n\n- **Hand-rolled OOXML exporters**:\n - `WordprocessingMLExporter`: Writes minimal-but-valid DOCX files with headings (via `w:pStyle`), emphasis (`w:b`/`w:i`), lists (`w:numPr`), tables, links (`w:hyperlink`), and embedded images. Deliberately mirrors `WordConverter`'s markers for round-trip validation.\n - `XLSXExporter`: Generates SpreadsheetML with one sheet per document section. Uses lossless `metadata[\"csv\"]` when present; otherwise flattens Markdown to rows (matching `DocumentRenderer.renderCSV`).\n - `PPTXExporter`: Creates PresentationML with one slide per top-level heading or explicit `.slide` section. Includes fixed template parts (slide master, layout, theme) via `PPTXTemplates`.\n\n- **Platform-native exporters**:\n - `AttributedStringRTFExporter`: Builds `NSAttributedString` from the Markdown IR and serializes to RTF (available across all Apple platforms).\n - `AttributedStringDOCXExporter`: Optional macOS-only DOCX writer using `NSAttributedString.officeOpenXML`; intentionally not registered by default (hand-rolled version is the primary).\n - `AttributedStringDocumentBuilder`: Shared utility that constructs attributed strings from `ConverterResult`, supporting headings, emphasis, lists, code, blockquotes, and tables.\n\n- **Infrastructure**:\n - `DocumentExporter` protocol: Sendable, synchronous serializers (pure CPU, no I/O).\n - `DocumentExporterRegistry`: Immutable, priority-ordered registry of exporters (mirrors `DocumentConverterRegistry`).\n - `OOXMLPackageWriter`: In-memory ZIP builder for OOXML files (no temp files; pure `Data` output).\n - `ExportableFileType`: Enum for writable formats (DOCX, XLSX, PPTX, RTF, Pages, Keynote). Pages/Keynote are marked unimplemented with research notes explaining why third-party iWork writing is impractical.\n - `OfficeMediaType`: Shared MIME type mapping for image extensions (used by both readers and writers).\n\n- **Engine API**: Added `PicoDocsEngine.write(result:to:registry:)` and `PicoDocsEngine.write(markdown:to:)` for serialization.\n\n- **Tests**: `ExporterTests` validates round-trip (write → re-import with existing converters → compare recovered text) for DOCX and XLSX, and structural validation for PPTX (unzip, required parts, title text).\n\n- **Documentation**: Updated README with export examples.\n\n## Notable Implementation Details\n\n- **Round-trip oracle**: DOCX/XLSX exporters are validated by re-importing with `WordConverter`/`SpreadsheetConverter` and comparing recovered Markdown, using the readers as ground truth.\n- **Markdown IR extraction**: `DocumentRenderer`'s inline helpers remain for\n\nhttps://claude.ai/code/session_01MRakJBZVBQ4CcTdcypk9Z6\n![high](https://www.gstatic.com/codereviewagent/high-priority.svg)\n\nXML 1.0 documents do not allow certain control characters (e.g., `0x00` to `0x08`, `0x0B`, `0x0C`, `0x0E` to `0x1F` except tab, newline, and carriage return). If these characters are present in the text (for example, extracted from PDFs or generated by LLMs), writing them directly into the XML will result in corrupted office files that fail to open in Microsoft Office. We should sanitize the input string by filtering out these invalid XML characters.\n\n```suggestion\n static func escape(_ text: String) -> String {\n let sanitized = String(text.unicodeScalars.filter { scalar in\n let val = scalar.value\n return val == 0x9 || val == 0xA || val == 0xD ||\n (val >= 0x20 && val <= 0xD7FF) ||\n (val >= 0xE000 && val <= 0xFFFD) ||\n (val >= 0x10000 && val <= 0x10FFFF)\n })\n return sanitized.replacingOccurrences(of: \"&\", with: \"&\")\n .replacingOccurrences(of: \"<\", with: \"<\")\n .replacingOccurrences(of: \">\", with: \">\")\n }\n```\n![medium](https://www.gstatic.com/codereviewagent/medium-priority.svg)\n\nIf the image source in the Markdown contains a path (e.g., `word/media/pic.png`) rather than just the basename, looking up `images[source]` will fail because the `images` index is keyed by the last path component (basename). To make the lookup robust, we should fall back to checking the last path component of the source string.\n\n```suggestion\n private func imageRun(alt: String, source: String) -> String? {\n let key = images[source] != nil ? source : (source as NSString).lastPathComponent\n guard let data = images[key] else { return nil }\n```\n![medium](https://www.gstatic.com/codereviewagent/medium-priority.svg)\n\nMapping each `UnicodeScalar` individually to a `Character` and then joining them breaks multi-scalar grapheme clusters (such as flag emojis, skin tone modifiers, or family emojis) into separate characters. To preserve grapheme clusters, we should map the scalars to a new `UnicodeScalarView` first, and then convert that view to a `String`.\n\n```suggestion\n private static func sanitizeSheetName(_ name: String) -> String {\n let invalid = CharacterSet(charactersIn: \":\\\\/?*[]\")\n let cleanedScalars = name.unicodeScalars.map { invalid.contains($0) ? UnicodeScalar(32) : $0 }\n let cleaned = String(String.UnicodeScalarView(cleanedScalars))\n .trimmingCharacters(in: .whitespacesAndNewlines)\n return String(cleaned.prefix(31))\n }\n```\n![medium](https://www.gstatic.com/codereviewagent/medium-priority.svg)\n\nCompiling regular expressions is relatively expensive. Since `parseEmphasis` is called recursively on inline runs, compiling the three regular expressions on every single call introduces unnecessary CPU overhead. We should compile them once as static properties of the parser.\n\n```swift\n private static let strongEmphasisRegex = try! NSRegularExpression(pattern: \"\\\\*\\\\*\\\\*(.+?)\\\\*\\\\*\\\\*\")\n private static let strongRegex = try! NSRegularExpression(pattern: \"\\\\*\\\\*(.+?)\\\\*\\\\*\")\n private static let emphasisRegex = try!

Feedback on the changes highlights several key improvement opportunities: sanitizing invalid XML 1.0 control characters to prevent corrupted office files, making image lookups robust against path prefixes, preserving multi-scalar grapheme clusters (such as emojis) during sheet name sanitization, and pre-compiling regular expressions in the inline parser to avoid recursive overhead.\n\n> [!IMPORTANT]\n> The [consumer version of Gemini Code Assist on GitHub](https://developers.google.com/gemini-code-assist/docs/review-repo-code) is being sunset.

The later package write then adds `word/media/` multiple times, which either fails on duplicate ZIP entries or creates an invalid OOXML package with duplicate part names. Cache emitted media by source/filename and reuse it instead of appending a new part per run.\n\nUseful?

Keep the filename for the media target, but write the escaped `alt` into the drawing alt-text attributes (at least `wp:docPr descr`).\n\nUseful?

The ZIP can still be produced, but the XML parts are not well-formed and Office/readers will reject the output; because raw Markdown writes do not run `sanitizeUnicode`, the OOXML escaping path should drop or replace disallowed XML characters before serialization.\n\nUseful?

\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Honor escaped label delimiters when parsing links**\n\nCanonical Markdown from `WordConverter` escapes `[`/`]` in link labels and image alt text, but this delimiter search treats an escaped `\\]` as the end of the label. When transcoding a DOCX link or image whose visible text contains `]`, the parser fails to recognize the link/image and the exporter writes literal Markdown instead of the original object; skip backslash-escaped delimiters and unescape the label before building the inline node.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Handle balanced parentheses in link destinations**\n\nFor raw Markdown passed to `write(markdown:)` with a common URL such as `[spec](https://example.com/Foo_(bar))`, this stops the destination at the first `)`, so the generated DOCX relationship target is truncated and the remaining `)` is emitted as ordinary text. Since this API is advertised for LLM Markdown output, parse balanced parentheses (or normalize to angle-bracket destinations) before creating office hyperlinks.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Restart each ordered list with distinct numbering**\n\nWhen a Markdown document has two separate ordered lists with prose between them, every ordered list item is assigned the same `numId` and Word treats the second list as a continuation of the first instead of restarting at 1. Allocate a fresh numbering instance (or a start override) per ordered-list block so exported DOCX files preserve Markdown list boundaries in Word/Pages.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Render image-only results instead of blank files**\n\nThis exception lets a `ConverterResult` that contains only `.image` sections pass validation, but the built-in exporters build their visible content from `result.markdown()` (which excludes `.image` carriers) and only embed images that are referenced inline. Passing an image-only result therefore produces a blank DOCX/PPTX/RTF or placeholder XLSX instead of the advertised valid image output; either synthesize image references for these sections or reject image-only results for formats that cannot render them.\n\nUseful? React with 👍 / 👎.\nThanks @gemini-code-assist and @chatgpt-codex-connector — worked through all the review threads. Pushed in `be8f6a1` and `66d1511`. Summary of each:\n\n**Fixed**\n- **XML 1.0-invalid control chars** (Gemini HIGH + Codex P2, `OOXMLPackageWriter.escape`): now filters disallowed scalars (NUL, vertical tab, etc.) before escaping, so raw `write(markdown:)` input — which skips `sanitizeUnicode` — can't produce non-well-formed `document.xml`/worksheet/slide parts.\n- **Image lookup by basename** (Gemini, `WordprocessingMLExporter`): falls back to the source's last path component when it carries a path prefix.\n- **Sheet-name grapheme clusters** (Gemini, `XLSXExporter`): rebuilds via `UnicodeScalarView` so emoji / multi-scalar clusters survive sanitization.\n- **Pre-compiled emphasis regexes** (Gemini, `MarkdownInline`): the three matchers are compiled once instead of per recursive call.\n- **Duplicate media parts** (Codex P2): repeated references to the same image now reuse a single media part + relationship (unique drawing ids), avoiding duplicate ZIP entries.\n- **Alt text in DOCX drawings** (Codex P2): Markdown alt text is written to `wp:docPr/@descr`, which `WordConverter.imageAltText` reads first, so it round-trips instead of collapsing to the filename.\n- **Escaped label delimiters** (Codex P2, `MarkdownInline`): the label scan skips backslash-escaped `\\]` and unescapes the recovered label.\n- **Balanced parens in destinations** (Codex P2): bare link/image destinations match balanced parentheses, so `https://e.com/Foo_(bar)` isn't truncated.\n- **Ordered-list restart** (Codex P2): each ordered list gets its own numbering instance with a `startOverride`, so Word restarts separate lists at 1 instead of continuing.\n- **Image-only results render blank** (Codex P2, `PicoDocs.write`): image-only `ConverterResult`s now synthesize an inline `[alt](name)` reference per `.image` carrier so the bytes are actually embedded, keeping the \"image-only doc is valid output\" contract honest.\n\nAdded tests covering image-only export, balanced-paren links, and escaped label delimiters. The Swift 6 build error from the first push (a non-`Sendable` closure in the static regex table) is fixed in `66d1511` by keeping only the compiled regexes in static storage.\n\n---\n_Generated by [Claude Code](https://claude.ai/code)_\nThanks for the detailed summary of the fixes, @ronaldmannak. The approach to sanitizing XML scalars in `OOXMLPackageWriter` and the extraction of the `MarkdownBlockParser` and `MarkdownInlineParser` into shared IRs are excellent improvements for maintainability and correctness. The added tests for image-only exports and edge cases like balanced parentheses in links are also great to see.

Treating every heading as a row here means `transcode(..., to: .xlsx)` inserts the worksheet name into cell A1 and shifts the original spreadsheet data down by one row, corrupting round-tripped XLSX content. Skip the section-title heading for sheet sections or prefer a lossless row source for spreadsheet-derived sections.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Generate a fallback name for unnamed image carriers**\n\nThe new synthesis path still drops any `.image` carrier that lacks both `sourcePath` and `title`, even though those fields are optional and `write(_:)` treats any image section as valid non-empty input. In that case an image-only result with valid `metadata[\"base64\"]`/`metadata[\"mimeType\"]` passes validation, `refs` stays empty, and the exporters receive no inline reference to the bytes, so the call succeeds with a blank/placeholder document instead of rendering the image; synthesize a stable filename from the index and MIME type instead of returning nil.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Make RTF support reflect the current platform**\n\nOn non-Apple platforms the default registry does not register `AttributedStringRTFExporter` because it is inside `#if canImport(AppKit) || canImport(UIKit)`, so `.rtf` writes throw `unableToExportToRequestedFormat`; however `isImplemented` still reports `.rtf` as supported. Server/Linux callers that use this property to advertise available export formats will offer an option that the built-in writer cannot fulfill, so gate `.rtf` the same way the registry does or document a separate availability API.\n\nUseful?

\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Preserve path-qualified image identities in DOCX export**\n\nWhen callers provide a structured result with two image sections such as `charts/logo.png` and `headers/logo.png` and matching inline refs, this index collapses both carriers to the same basename key and the later section overwrites the earlier bytes. Both drawings then resolve to the same media part even though `imageRun` tries to support path-prefixed sources, so distinct images with equal basenames are rendered incorrectly; index by source path as well as basename, and only fall back to basename when it is unambiguous.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Use image MIME metadata when adding missing extensions**\n\nFor an embedded image whose reference/name has no extension but whose `.image` section carries `metadata[\"mimeType\"]` (for example `image/png`), this derives the fallback extension by first asking for the MIME type of an empty extension, which always becomes `application/octet-stream`, and then maps that to `.bin`. The resulting DOCX stores `word/media/.bin` with an octet-stream content type, so Office cannot reliably recognize or render otherwise valid PNG/JPEG bytes; carry the section MIME through the image index and use it here when `ext.isEmpty`.\n\nUseful?

Summary of each:\n\n**Fixed**\n- **XML 1.0-invalid control chars** (Gemini HIGH + Codex P2, `OOXMLPackageWriter.escape`): now filters disallowed scalars (NUL, vertical tab, etc.) before escaping, so raw `write(markdown:)` input — which skips `sanitizeUnicode` — can't produce non-well-formed `document.xml`/worksheet/slide parts.\n- **Image lookup by basename** (Gemini, `WordprocessingMLExporter`): falls back to the source's last path component when it carries a path prefix.\n- **Sheet-name grapheme clusters** (Gemini, `XLSXExporter`): rebuilds via `UnicodeScalarView` so emoji / multi-scalar clusters survive sanitization.\n- **Pre-compiled emphasis regexes** (Gemini, `MarkdownInline`): the three matchers are compiled once instead of per recursive call.\n- **Duplicate media parts** (Codex P2): repeated references to the same image now reuse a single media part + relationship (unique drawing ids), avoiding duplicate ZIP entries.\n- **Alt text in DOCX drawings** (Codex P2): Markdown alt text is written to `wp:docPr/@descr`, which `WordConverter.imageAltText` reads first, so it round-trips instead of collapsing to the filename.\n- **Escaped label delimiters** (Codex P2, `MarkdownInline`): the label scan skips backslash-escaped `\\]` and unescapes the recovered label.\n- **Balanced parens in destinations** (Codex P2): bare link/image destinations match balanced parentheses, so `https://e.com/Foo_(bar)` isn't truncated.\n- **Ordered-list restart** (Codex P2): each ordered list gets its own numbering instance with a `startOverride`, so Word restarts separate lists at 1 instead of continuing.\n- **Image-only results render blank** (Codex P2, `PicoDocs.write`): image-only `ConverterResult`s now synthesize an inline `[alt](name)` reference per `.image` carrier so the bytes are actually embedded, keeping the \"image-only doc is valid output\" contract honest.\n\nAdded tests covering image-only export, balanced-paren links, and escaped label delimiters. The Swift 6 build error from the first push (a non-`Sendable` closure in the static regex table) is fixed in `66d1511` by keeping only the compiled regexes in static storage.\n\n---\n_Generated by [Claude Code](https://claude.ai/code)_","**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Render image-only results instead of blank files**\n\nThis exception lets a `ConverterResult` that contains only `.image` sections pass validation, but the built-in exporters build their visible content from `result.markdown()` (which excludes `.image` carriers) and only embed images that are referenced inline. Passing an image-only result therefore produces a blank DOCX/PPTX/RTF or placeholder XLSX instead of the advertised valid image output; either synthesize image references for these sections or reject image-only results for formats that cannot render them.\n\nUseful?

Now a *leading* heading that echoes `sheetName`/`title` is dropped (genuine in-body headings stay).\n- **`.rtf` over-reports availability** (`ExportableFileType.isImplemented`): the RTF writer is registered only under `#if canImport(AppKit) || canImport(UIKit)`, so `.rtf` is now gated the same way and Linux callers no longer advertise an export that throws.\n- **Same-basename images collapse** (`WordprocessingMLExporter` image index): rebuilt as a struct assigning each carrier a unique, correctly-typed media filename; keyed by full source path **and** by unambiguous basename, so `charts/logo.png` and `headers/logo.png` write two distinct parts (`logo.png`, `logo-2.png`).\n- **Wrong extension for MIME-only images**: the missing extension is now taken from the carrier's MIME (`image/png` → `.png`) at index-build time, so valid bytes are no longer stored as `.bin`/octet-stream.\n- **Unnamed image carriers dropped** (`withSynthesizedImageReferences`): a carrier with only `base64`/`mimeType` now gets a stable `image-.` name (ext from MIME), assigned as its `sourcePath` so the exporter index resolves the same key — image-only results with such carriers embed instead of producing a blank document.\n\nTests added: XLSX sheet title isn't a data cell; same-basename images stay distinct; an unnamed MIME-only image embeds as `.png`; `.rtf` availability matches the
