Sync third-party and MCP marketplace plugins

Constraint: Public skills are published only by explicit administrator action unless they are tracked third-party market sources. Confidence: high Scope-risk: narrow Directive: Keep private/internal skills out of the public marketplace and preserve normal incremental market Git history. Tested: Marketplace validation passed.

-Free-design and brand-only pages are also structured from the first draft. Use the planned Master roster and page Layout mapping, author Master/Layout fixed visuals only as direct root atoms (never `<g>`), and author reusable content zones as top-level slot groups with positive bounds plus exactly one compatible carrier. Every mapped page MUST mark the standard slots it actually has — `title` / `subtitle` / `body` / `picture` / `slide-number` / `footer` — and its `data-pptx-layer` marks: the deck-wide background and every-page chrome as `master`, this layout key's static framing (including chrome repeated on content pages but absent from the cover) as `layout`, per [`executor-base.md`](references/executor-base.md) §1.2. Repeated chrome stays on its appropriate Master/Layout layer; a per-page heading that should not remain Slide-local is authored as a `title` or `subtitle` slot, never as a fixed Layout atom. Any text or image whose value varies across pages sharing one Layout key MUST be carried by a slot or remain Slide-local. A page shipping only a marked background exports a bare Master and an empty Layout. A Layout may intentionally have zero slots — a stated decision for a fixed composition, never a silent default. Do not add `data-pptx-layout-kind`, `distilled`, `utility`, or a full-page fake slot.

Export materializes one clean project-owned Master plus one Blank Layout, applies the locked theme colors/fonts/title-body defaults, removes stock content placeholders and unused built-in Layouts, and retains only the standard date/footer/slide-number capability hooks. It does not promote or deduplicate page content.

 Do not duplicate specialized identity with `data-pptx-role`. Add it only to structural page-frame objects whose package, page-number, or animation behavior is not already expressed by `data-pptx-layer`, `data-pptx-placeholder`, or `data-pptx-native`; such an element needs a stable unique `id`.

On deck/layout template routes, root Master/Layout identity, atomic layer elements, grouped slots, and native-object metadata are authoritative and read first; each page carries its final structured contract from the start of SVG authoring.

Dense decks may legitimately be all `dense`. **Do NOT invent filler pages** ("Thank you", empty dividers) to pad rhythm — every `breathing` page must say something independent. Delivery purpose biases the overall lean (`presentation` toward more `anchor` / `breathing`, `text` toward `dense`; see §6.1) — a bias, never a quota.
   - **Cover impact is mandatory**: Page `P01` is the deck's first visual contract, not a generic title slide.

Use the source's strongest available signal: a provocative core claim, object / scene metaphor, hero number, founder / product / audience moment, or a distilled conflict. Pair it with one concrete composition strategy — such as `full-bleed image + floating title`, `typographic poster`, `hero object`, `data hook`, `editorial scene`, `high-contrast abstract geometry`, or a fresh composition the deck's subject suggests (these are starting points, not the allowed set). If no external or AI image is available, still specify a native-SVG visual hook; do not fall back to "title + subtitle + decorative background". (Beautify / template-fill keep the source cover verbatim — this rule does not apply on those preservation paths.)

   - **Closing impact (only when the deck closes)**: the deck's last page is its final visual contract — the strongest impression after the cover. When the deck genuinely lands on a conclusion / call-to-action / final-takeaway page, give it a `Closing impact` line in §IX: name the one thing the audience should leave with (a distilled takeaway, a forward call, a memorable restatement of the core claim) + one composition that delivers it — never a generic "Thank you" / contact-only slide or a centered-title reprise of the cover. **Do NOT invent a closing page to satisfy this** — the filler-page ban above still holds; apply it only to the page where the deck actually resolves. Same exemptions as the cover: skip on template / beautify / template-fill preservation paths.
-   - **pptx_structure is mandatory**: Every new project writes `mode: structured`. Free design and brand-only routes default to one Master; add another only when the design genuinely needs it. Deck/layout templates also record `template_adherence: strict|adaptive`. Do not write `baseline`, `template`, `preserve`, `flat`, `layout_strategy`, or Layout-kind rows into a new project.
-   - **Master roster**: Write one `pptx_masters` row per Master as `<master_key>: <picker name>`. For a template, copy the restored prototype roster. For free design, define stable deck-wide background/chrome atoms at planning time; Master visuals are root-level atomic elements and may never be `<g>`.
-   - **pptx_layouts (native output contract)**: Write exactly one row per page before generation as `<master_key> | <layout_key> | <PowerPoint layout name>`. Plan semantic Layout families from the outline and reuse a key only when fixed Layout atoms plus slot ids/types/indices/bounds/binding modes are identical. Name each key after its composition (`timeline-spine`, `kpi-band-trio`, `content-image-right`), never after a PowerPoint stock role or the page's topic. A Layout may intentionally have zero slots; never manufacture an empty `utility` kind or full-page fake slot. **Self-check before writing the section**: compare distinct keys against the distinct compositions in §IX. Distinct compositions collapsing into a handful of stock-role keys (`cover` / `title-content` / `section`) means pages were clustered by role; one shared skeleton splitting into per-topic keys (`allocation-fengqing` / `allocation-luoping`) means pages were split by topic. Both misstate the roster — re-derive from composition.
-   - **Slot planning**: Each reusable slot is a direct root `<g id>` with `data-pptx-placeholder`, positive design-zone bounds, and exactly one compatible direct carrier. Bounds come from the intended safe area, column, panel inset, or media frame—not sample text ink. A genuinely composite region may use only the explicit `object` + `proxy` downgrade.
-   - **Adaptive refinement boundary**: The initial mapping is complete, not provisional. If actual adaptive construction genuinely changes reusable framing or slot topology/bounds, Executor creates a new Layout key and updates `spec_lock.md` while authoring that first page. It never mutates a reused contract silently. Export only compiles declared structure and never discovers or clusters Layouts.
-   - **page_layouts (deck/layout templates only)**: Add one `P<NN>: <svg_basename>` row for every page. This is the complete input-prototype mapping. Strict preserves that SVG's structural contract; adaptive keeps its Master and may explicitly assign a new output Layout identity during page authoring.

Do not plan native Master/Layout families or reusable placeholder slots. Every generated SVG object remains Slide-local: omit root Master/Layout identity, `data-pptx-layer`, and `data-pptx-placeholder*` metadata. Export materializes one clean project-owned Master plus one Blank Layout from the current color/typography lock, removes stock content placeholders/Layout inventory, and retains only the standard date/footer/slide-number capability hooks.
+   - **Master roster (deck/layout templates only)**: Write one `pptx_masters` row per Master as `<master_key>: <picker name>` and copy the restored prototype roster. Master visuals are root-level atomic elements and may never be `<g>`.
+   - **pptx_layouts (deck/layout template reusable roster)**: Write every unique reusable Layout once as `<layout_key>: <master_key> | <PowerPoint layout name> | <prototype source>`. Copy the installed template roster with `template:<basename>` sources, including Layouts no generated page currently uses. A genuinely new adaptive Layout uses its first generated `P<NN>` as the source. Reuse a key only when fixed Layout atoms plus slot ids/types/indices/bounds/binding modes are identical. Name authored keys after composition (`timeline-spine`, `kpi-band-trio`, `content-image-right`), never after page topic. A Layout may intentionally have zero slots; never manufacture an empty `utility` kind or full-page fake slot.
+   - **page_pptx_layouts (deck/layout template page assignment)**: Write exactly one `P<NN>: <layout_key>` row per generated page. The key must exist in `pptx_layouts`; Master and picker name are inherited from that unique definition. **Self-check before writing the section**: compare distinct assigned keys against distinct compositions in §IX. Distinct compositions collapsing into a handful of role-only keys means pages were clustered by topic label; one shared skeleton splitting into topic-specific keys means pages were split by content wording. Both misstate the roster.
+   - **Slot planning (deck/layout templates only)**: Each reusable slot is a direct root `<g id>` with `data-pptx-placeholder`, positive design-zone bounds, and exactly one compatible direct carrier. Bounds come from the intended safe area, column, panel inset, or media frame—not sample text ink. A genuinely composite region may use only the explicit `object` + `proxy` downgrade.
+   - **Adaptive refinement boundary (deck/layout templates only)**: The initial definitions and assignments are complete, not provisional. If actual adaptive construction genuinely changes reusable framing or slot topology/bounds, Executor creates one new `pptx_layouts` definition sourced from that page and updates its `page_pptx_layouts` assignment while authoring the first page. It never mutates a reused contract silently. Export only compiles declared structure and never discovers or clusters Layouts.
+   - **page_layouts (deck/layout templates only)**: Add one `P<NN>: <svg_basename>` row for every page. This is the complete authoring-input prototype mapping. Strict preserves that SVG's structural contract; adaptive keeps its Master and may explicitly define and assign a new output Layout identity during page authoring. Omit the whole section for free-design and brand-only routes.
   - **page_charts (write only for chart pages that match a catalog template)**: For each page in `design_spec.md §VII` whose `reference template path` points to `templates/charts/<name>.svg`, add `P<NN>: <chart_name>`. Pages with `no-template-match` in §VII MUST NOT appear here (Executor would look for a non-existent reference). If the deck has no data-visualization pages, omit the section.
   - **Hard rule**: Use both `page_layouts` and `page_charts` only with a compatible template shell. For a chart page without an exact roster match, adaptive mode selects the closest neutral input prototype and assigns an explicit output Layout key in the planning map; strict mode must select an existing compatible Layout or revise the outline. Never omit `page_layouts` inside a new deck/layout template route.

-Anthropic uses a six-petal star **mark** that is most commonly seen locked up with a product wordmark. The bundled lockup pairs the mark with the **Claude** wordmark, since that is the live lockup on claude.com. Pick by context, never combine on the same page.
+This preset intentionally combines Anthropic company voice with Claude product visuals. The bundled star and wordmark belong to Claude; they are not relabeled as an Anthropic corporate mark. Pick one Claude asset by context and never combine several lockups on the same page.

-## V. Page Structure
-
-### General Layout
-
-| Area | Position | Description |
-| --- | --- | --- |
-| **Logo Area** | x=72, y=36 | Fixed top-left brand logo |
-| **Header Ribbon** | y=32 to 96 | Red capsule + gray lane for TOC/content pages |
-| **Main Content Area** | y=132 to 618 | Main text/layout body |
-| **Visual Sidebar** | x=922 to 1208 | Fixed image-only rail on cover / TOC / chapter / ending pages |
-| **Footer Ribbon** | y=548 to 720 | Fixed decorative bottom image area on cover/ending |
-| **Footer Meta** | y=650 to 690 | Source / page number / contact info |
-
-### Structural Rules
-
- Cover and ending pages reuse the image-based footer ribbon to preserve the brand atmosphere.
- TOC and content pages use dedicated visual sidebars/cards for imagery, keeping text and images in separate safe zones.
- Chapter pages are cleaner section-divider pages and should not inherit the content-page header ribbon.
- Each page should contain at most one formal logo mark; sidebars should rely on slogan and skyline imagery instead of repeated logo lockups.
- The content page remains open-canvas by default and should not reserve a large fixed sidebar.
- Repeated telecom motifs use one reusable structure family rather than unrelated decorative variants.
-

-
-## VI. Page Types
-
-### 1. Cover Page (`01_cover.svg`)
-
- Top-left fixed logo

-## XI. Usage Guide
-
-1. Reuse `logo.png` and `footer_ribbon.png` as fixed brand assets; `slogan_red.png` and `skyline_bg.png` should be used selectively and only on the cover / ending pages.
-2. Keep generated text inside the documented safe areas; only chapter pages use a strong left/right split.
-3. Prefer red emphasis only for structure and key figures; do not over-saturate the content area.
-4. Reference only assets packaged with this template.
+| logo.png | 封面、章节页和结束页品牌标识 |

+| skyline_bg.png | 右侧品牌卡片城市线稿 |

+- 白底内容页使用“蓝色方形章节号 + 左对齐标题 + 右上角 Logo”的稳定页眉。
+- 封面、章节页和结束页保留深蓝底、低透明度圆形与细网格，但删除无内容价值的复杂渐变和动态图片依赖。
+- CATARC Dark Master 统一承载深蓝背景和上下结构线；章节页与结束页各自保留原稿中的圆形几何，封面不继承圆形。CATARC Light Master 统一承载白底、章节号方块、页眉 Logo、分隔线和底部蓝线。
+- 目录页延续数字与双竖线的行式导航，并保留右侧独立数据对象区。
+- 通用内容对象从框体左上角开始；封面、章节页、结束页以及小型章节号属于短焦点内容，允许在完整占位框中居中。

-### Design DNA
-

-2. Keep cover / chapter / ending pages visually strong and brand-led.
-3. Keep content pages bright and practical for data, process, and case-study layouts.
-4. Preserve a secondary finance-blue accent to support comparison and case storytelling.
-5. Maintain content coverage ≤ 60%, ensuring visual "breathing room" on data-heavy pages.
-6. Use structured layouts (cards, grids, process flows) to organize financial data clearly.
-
-## VI. Page Types
-
-### 1. Cover Page (`01_cover.svg`)
-
- Uses the imported cover background asset `cover_bg.png`
- Centered white typography with restrained divider lines
- Suitable for title, subtitle, presenter, and date
-
-### 2. Table of Contents (`02_toc.svg`)
-
- Light page with red top strip and logo
- Two-column indexed list for up to four agenda items
- Red numerals + dark text for fast scanning
-
-### 3. Chapter Page (`02_chapter.svg`)
-

-
-### 4. Content Page (`03_content.svg`)

- Page title, section label, key message line, and open body region
- Footer includes section name, source, and page number

-| --- | --- |
-| **Process / Flow** | Use full-width body area with 3-6 horizontal stages |

-## V. Core Visual Elements
-
-### 1. Diagonal Color Blocks (Mountain City Layers)
-
-The template's signature design uses diagonally divided color blocks to simulate the layered terrain of the Mountain City:
-
-```
-Cover: Large deep-blue diagonal block in the lower-left corner (approx. 40% of area)
-Chapter page: Full-screen deep blue + light diagonal accent in the upper-right
-Content page: Small diagonal accent strip at the top
-```
-
-### 2. Wave Patterns (Two Rivers Imagery)
-
-Abstract curves symbolizing the Yangtze and Jialing Rivers:
-
-```xml
-<path d="M0,700 Q320,680 640,700 T1280,680 L1280,720 L0,720 Z"
-      fill="#006BB7" fill-opacity="0.08"/>
-```
-
-### 3. Light Dot Decorations (City Lights)
-
-Small circle elements representing the nighttime lights of the Mountain City:
-
-```xml
-<circle cx="x" cy="y" r="3" fill="#D4A84B" fill-opacity="0.6"/>
-```

 > **Audit rule**: `Summary-quote` must be copy-pasted verbatim — paraphrasing breaks the audit. Every template name listed must `grep` cleanly inside `charts_index.json` (so misspellings/inventions fail). If fewer than 3 viz pages exist, list what exists and note "fewer than 3 viz pages"; runners-up still required for each page that does exist.

+> **Native-preset candidates → append to `Usage`**: for a page already in this list, when its content calls for a literal stock PowerPoint shape (chevron, block arrow, standard flowchart node, callout, banner, star — judged from the page plan, not a template's name), append a candidate note to that page's `Usage`, e.g. `…usage…; native-preset candidate: chevron; Executor applies executor-base §3.0`. The Executor still selects the exact preset, frame, and paint. See [`strategist.md`](../references/strategist.md) Template Match.

-> **Native Layout boundary**: Each `Layout` line below describes visual composition intent and feeds the planning-time structured mapping. Before SVG generation, Strategist writes the Master roster and exactly one `<master_key> | <layout_key> | <PowerPoint layout name>` row per page. Free-design/brand-only pages use that structure from their first draft; template pages also select an input prototype through `page_layouts`. Strict preserves the prototype contract. Adaptive keeps its Master and may assign a new Layout key during page authoring only when fixed Layout atoms or slot topology/bounds change. Legacy prototypes first run [`restore-pptx-structure`](../workflows/restore-pptx-structure.md); no deferred distillation or immediate-compatibility fallback exists.
+> **Native Layout boundary**: Each `Layout` line below always describes visual composition intent. On free-design and brand-only routes, it does not create native Master/Layout identity: `spec_lock.md` uses `pptx_structure.mode: flat`, omits `pptx_masters` / `pptx_layouts` / `page_pptx_layouts` / `page_layouts`, and every SVG object stays Slide-local. Export materializes one clean project-owned Master plus one Blank Layout from the current lock, removes stock content placeholders/Layout inventory, and retains only the standard date/footer/slide-number capability hooks. Deck/layout template routes use `mode: structured`: Strategist writes each unique Master/Layout definition once, assigns every page through `page_pptx_layouts`, and selects its authoring prototype through `page_layouts`. Strict preserves the prototype contract. Adaptive keeps its Master and may define and assign a new Layout key during page authoring only when fixed Layout atoms or slot topology/bounds change. Legacy prototypes first run [`restore-pptx-structure`](../workflows/restore-pptx-structure.md); no deferred distillation or immediate-compatibility fallback exists.

-
-## III. Core Design Principles
-
-### Telecom High-Density Information Style
-
-This template emulates the visual language of telecom technical reports. The core characteristics are "**modular zoning + high information density + red-blue dual-color hierarchy**".
-
-1. **Left Red Vertical Bar**: A red rectangle (10×40px) before titles serves as a visual anchor — the most essential title identifier throughout the template.
-2. **Number Badges**: Red square badges (30×30px with white numbers) identify key initiatives/capability numbers (e.g., numbers 1-5 in "Five Key Initiatives").
-3. **Dashed Zone Frames**: `stroke-dasharray="5 5"` dashed rectangles group content modules, creating a structured, modular visual effect — a common "zone frame" in telecom reports.
-4. **Blue Label Bars**: `#2E75B6` blue-filled rectangles (full-width or fixed-width) serve as scenario/category headers carrying scenario names.
-5. **Warm Gray Overview Panels**: Panels with `#FDF3EB` background + `#F8CBAD` border carry overviews, summaries, and open platform entries.
-6. **Metric Card Groups**: White cards with `#F2F2F2` borders, closely arranged to display KPI metrics; values highlighted in `#C00000` red.
-7. **Light Blue Sub-modules**: `#5B9BD5` filled small rectangular cards displaying specific feature items (e.g., "AI One-Click Troubleshooting Assistant").
-8. **Gray Capability Base Cards**: Cards with `#E7E6E6` / `#F2F2F2` background for displaying foundational capabilities/platform components.
-
-### Advanced Features
-
-1. **Triangle Decorations**: The top area may use light semi-transparent triangles (`fill-opacity="0.3"`) as visual guides.
-2. **Star/Icon Accents**: Simple polygon stars near key achievements enhance visual impact.
-3. **Multi-level Nested Zones**: Outer dashed frame > inner label area > specific feature cards, forming a three-layer visual hierarchy.
-4. **Compact Line Spacing**: Module spacing compressed to 10-20px to maximize information capacity.

-## IV. Page Structure
-
-### General Layout
-
-| Area               | Position/Height  | Description                                          |
-| ------------------ | ---------------- | ---------------------------------------------------- |
-| **Title Area**     | y=20-80          | Red vertical bar + title text + optional subtitle overview bar |
-| **Overview Bar**   | y=80-140         | Full-width `#F2F2F2` background bar carrying the page's core summary |
-| **Content Area**   | y=140-670        | Main content area (densely packed multi-module layout) |
-| **Footer**         | y=680-720        | Red narrow bar with page number + chapter name + source citation |
-
-### Navigation Bar Design
-
- **Title Vertical Bar**: Red rectangle `#C00000`, 10×40px, positioned left of the title text
- **Title Text**: 10px from the vertical bar, 36px font size, `#C00000` or `#000000`
- **Overview Bar**: Full-width light gray rectangle (h=60px), centered 16px body text carrying the page overview/introduction
-
-### Decorative Elements
-
- **Number Badges**: 30×30px red squares + white numbers (centered)
- **Blue Labels**: Fixed-width blue rectangles + white text (e.g., "Fault Boundary Identification")
- **Dashed Zone Frames**: `stroke="#C00000"` or `stroke="#E7E6E6"`, `stroke-dasharray="5 5"`
- **Warm Gray Panels**: `fill="#FDF3EB"` + `stroke="#F8CBAD"` + `stroke-width="2"`
- **Light Blue Feature Cards**: `fill="#5B9BD5"` rectangles + white text

-
-## VII. Layout Patterns
-
-| Pattern                        | Applicable Scenarios                              |
-| ------------------------------ | ------------------------------------------------- |
-| **Architecture Overview**      | AI operations overview, system architecture panorama |
-| **Metrics Dashboard**          | KPI display, performance reports, data dashboards |
-| **Multi-Module Zoning**        | Capability lists, scenario matrices, domain displays |
-| **Process/Timeline**           | Implementation roadmap, deployment plan, evolution path |
-| **Top-Bottom Split**           | Objectives+results (top), scenarios+capabilities (bottom) |
-| **Left-Right Split (3:7)**     | Left navigation labels + right content area       |
-| **Card Matrix (2x3/3x3)**     | Capability modules, team assignments, project lists |
-| **Table**                      | Metric comparisons, progress tracking             |
-
-> **Recommended**: Telecom reports commonly use the "**Architecture Overview**" pattern — a single page presenting the complete architecture from objectives → results → scenarios → orchestration → foundational capabilities, unfolding top to bottom.

-## IX. Spacing Specification
-
-| Element                        | Value     |
-| ------------------------------ | --------- |
-| Page left/right margins        | 30-50px   |
-| Page top/bottom margins        | 20-40px   |
-| Title area height              | 60px      |
-| Overview bar height            | 60px      |
-| Title to overview bar spacing  | 0px       |
-| Overview bar to content spacing | 10-20px  |
-| Module spacing                 | 10-20px   |
-| Card spacing                   | 10px      |
-| Card inner padding             | 15-20px   |
-| Badge to label spacing         | 5-10px    |
-| Footer height                  | 40px      |
-
-> **Compact Principle**: The telecom style pursues maximum information per page; spacing is generally 30-50% smaller than standard templates.
-

-## XII. Design Highlights
-
- **Telecom DNA**: Derived from real telecom AI operations architecture reports, naturally suited for telecom/enterprise presentation styles
- **High Information Density**: A single page can accommodate a complete architecture view (objectives → results → scenarios → orchestration → foundational capabilities)
- **Red-Blue Dual-Color Hierarchy**: Red = core/emphasis/objectives, Blue = scenarios/modules/capabilities — clear visual hierarchy
- **Number Badge System**: Red square numbers throughout create a "N Key Initiatives" visual narrative
- **Three-Level Nested Zoning**: Dashed outer frame → category labels → feature cards for structured expression of complex architectures
- **Metric Card Groups**: Compactly arranged KPI metrics with red-highlighted values for instant readability
