+# Authoring handoff
+
+Give every authoring step the same selected template ID/version, theme, layout, exported style, source specification, content and notes, strict input assets, approved visual references, editability policy and input hashes. These are local project inputs; reading another installed Skill is unnecessary.
+
+For the current page, decide the message and evidence first, then compose the page within the selected layout. A mockup image establishes visual direction; the editable deliverable is authored from independent objects. Reuse approved decisions and the user's page-by-page workflow. A known page count does not authorize creating the remaining pages in bulk.
+
+Native compilation uses the separate template's complete workspace roster, retaining Master, Layout and placeholder links. The final source page identifies its intended layout with `data-pptx-layout`. A whole-slide picture, selectable SVG picture or generic text reconstruction does not establish those links by itself. See [native authoring](native-authoring.md) and [object reconstruction](object-reconstruction.md).
+
+Native formulas, tables and charts need their own object checks. Bitmap or SVG formula assets remain pictures even when individually selectable. Exact logos, charts and scientific figures keep their originals and evidence meanings. If a specialized object cannot be reconstructed faithfully, record its picture exception and source rather than claiming native editability.
+
+This package carries no template, theme or global style library. Installation and source synchronization belong to the installation owner.
+
+A theme switch changes only declared palette and asset properties. Shared canvas, typography, geometry, layout/slot identities and content meaning remain fixed unless the template explicitly defines an exception. Rebuild and inspect affected pages after a switch. Recompilation sets the PowerPoint theme palette; it does not retroactively recolor undeclared source literals.
+
+## Icon material handoff
+
+Supply the original SVG, its `paint_contract_data`, selected palette and exact asset bindings together. New vector materials use stable element IDs and adjustable fill/stroke pairs with semantic tokens. Distinct tokens express independent roles; a shared token expresses a shared role. Keep fixed details as literal values and unpainted openings as `structural: none`. Undeclared channels preserve their source paint.
+
+`scripts/paint_asset.py --manifest <path> --theme <id> --asset <role> --output <new.svg>` applies only the selected theme's palette whitelist. It verifies exact IDs, explicit source paint, fixed/structural values and bindings, then protects existing output. It intentionally rejects stylesheets, overridden target channels and inherited target paint; flatten those channels into explicit reviewed attributes before using this helper. Other SVG authoring tools may support richer materials if they preserve the same contract.
+
+Do not replace colors across a whole image or infer roles from matching colors. Keep geometry, opacity, masks, paint order, fixed colors and `none` intact. Raster materials with independent color roles require layers or reviewed per-role alpha masks; a flat PNG's colors do not grant recoloring permission. Preserve original assets and record derivatives separately.
+
+Render the derived material on its intended background and compare it with the original. Structural gaps and fixed details must remain visible. Path/JSON/hash validation, SVG transformation, rendering, native structure and application editing are distinct evidence levels.

+# Native page authoring
+
+Read the selected external template's specification, style, theme and relevant layout first. The bundled compiler accepts the native SVG workspace convention: `templates/roster.json` maps every manifest layout ID to one SVG; each source SVG declares `data-pptx-master`, `data-pptx-layout` and friendly names. Layout and master objects use their declared `data-pptx-layer`. Placeholder groups carry `data-pptx-placeholder`, a stable `data-pptx-idx`, and `data-pptx-bounds`.
+
+Start the current page from its selected layout source. Retain inheritance metadata, inherited objects and placeholder indices. Fill the declared placeholder carrier; put independent content objects in the intended slide layer. Do not paint opaque slide-local copies over the master logo or layout watermarks. When a template supplies a custom composition generator, inspect it and use its declared content interface rather than approximating its source geometry.
+
+Use the template's discrete typography, grid, fixed content region and spacing. Resolve overflow by choosing a suitable layout, shortening content or dividing the page according to the user's workflow. Do not infer ad hoc font sizes and alignment guides from mockup pixels. Keep text as text, simple panels and connectors as geometry, and exact image exceptions as independent assets. Tables, charts and formulas must retain their required native object type; a collection of lines/text or a formula picture does not automatically qualify.
+
+## Current-page export
+
+The installer provides Python 3.12+ and [runtime requirements](../runtime/requirements.txt). Metadata-only selection and project commands use Python 3.10+ without third-party packages.
+
+```sh
+python3 /path/to/skill/scripts/native_export.py \
+  --manifest /path/to/separate-template/manifest.json \
+  --theme chosen-theme \
+  --source /path/to/current-page.svg \
+  --output /path/to/new-review.pptx \
+  --notes /path/to/notes.json
+```
+
+`--source` may repeat to assemble explicitly authorized, already authored pages in order. It does not create or design additional pages. Source filename stems must be unique. `--notes` is optional JSON mapping source stems to complete speaker-notes strings; unknown stems are rejected.
+
+The exporter consumes released v2 manifests and retains all native layout definitions, even for a single visible page. It requires a complete layout roster, unique layout names, declared `page_title`/`body` family roles and sizes, and the twelve PowerPoint theme color indices. Optional `style.language` supplies the presentation's BCP-47 language tag. Without it, the exporter preserves the compiler's legacy language metadata behavior; record the deck language in the project when it matters.
+
+Page SVG viewBox and layout ID must match the selected template. Source assets are only relative local PNG/JPEG references or embedded PNG/JPEG data. Fragment references are supported; external images, active SVG elements, document entities and external CSS URLs are refused. Default author resource boundary is each SVG's directory; template-internal sources use the template package root. For portable project pages that intentionally reference `../../assets/...`, pass `--source-root /path/to/project`. Boundaries and symlink checks apply before compilation. Other visual formats should be prepared as native geometry or explicit supported bitmap assets.
+
+The exporter embeds images in temporary source copies, preserving canonical source bytes. It runs the bundled attribution guard, serial compiler and declared-font preservation context, then applies the external palette/theme fonts and verifies slide/Layout/Master links, placeholders and supplied notes. Existing output is protected, including a concurrent writer appearing during compilation. A failed build does not replace old output.
+
+## Template authors and review prototypes
+
+Keep proposed styles and mockups outside the final template workspace until the user's design review allows formal construction. A proposal manifest cannot be consumed as a released production template. After approval, author the common style, independent themes, roster and native SVG layout definitions together; compare each theme against the same geometry and slot contract.
+
+The bundled runtime also carries the upstream preview compiler at `runtime/ppt-master/scripts/template_preview_pptx.py` for author review workspaces. It is source tooling, not a second Skill. Read its command help for a new workspace. Its platform font mapping is general-purpose: a template review wrapper should import the compiler and use `scripts/finalize_theme.py`'s `preserve_declared_font_families(style)` context around the serial compile, then `finalize(...)`. This preserves the declared family before information can be lost to platform fallback. Do not globally replace a fallback font in finished XML: the author may have intentionally used that same font.
+
+For advanced native table/chart/formula or placeholder metadata, inspect the corresponding bundled compiler module and its local CLI help. Do not claim specialized objects from a screenshot or from a successful ZIP export alone. Finish with [render and application checks](powerpoint-checks.md).

+# Reconstruct one visual page into editable objects
+
+Treat the current visual page as a design reference with explicit source fidelity requirements. Determine the background and asset boundaries before writing native text over it; otherwise old text and newly editable text can coexist invisibly in a background picture.
+
+Inventory the page: canvas, fixed UI, text levels, content groups, foreground images/icons, simple geometry/connectors, tables/charts, formulas, decorative patterns and intended layout slots. Keep every text value, evidence value and source asset tied to the user-provided content. Record each object's target type and source.
+
+## Background and materials
+
+Solid backgrounds, ordinary panels, divider bands, repeated geometric patterns, axes and simple connectors can be authored as native geometry. Reuse a clean image region when it contains none of the foreground that will be rebuilt. For a complex illustration/photo background obscured by replaceable text or objects, use the host image editor to remove only those objects while preserving scene identity, camera, composition, lighting and texture. Inspect the repaired result for invented content and smearing.
+
+Keep exact supplied logos, figures and screenshots as independent source assets. Use existing vector or layered assets when available. When visual identity depends on an inseparable bitmap illustration, isolate it through image editing or retain a disclosed image exception, according to the user's editability requirements. Do not replace it with an unrelated icon, approximate illustration or whole-page crop without authorization.
+
+## Native reconstruction
+
+Start from the selected template layout source, retaining its Master/Layout/placeholder metadata. Recreate normal text as native text with the external style's font family, discrete size, line spacing and alignment. Build simple panels, rules, arrows and diagram nodes as separate structural objects. Fit to the declared grid, not pixel-by-pixel ad hoc anchors.
+
+Use actual data for native charts; if source values are unavailable, preserve the chart as an evidence image and say why. A native table uses native cells; native formulas require actual editable equation objects where the chosen compiler supports them. A formula bitmap, SVG picture or vector outline is still a picture/path exception. Preserve formula meaning and verify symbols against the source before conversion.
+
+Preserve crop, aspect ratio and source meaning for image objects. Independently editable text over an unchanged full-page screenshot is not a reconstructed page. Keep repeated UI in inherited layers, rather than covering it with copied slide objects.
+
+Compile the current SVG through [native export](native-authoring.md), then compare the actual rendered page with the accepted design at full size and a normal presentation view. Check hierarchy, density, line breaks, safe margins, alignment, clipping, asset identity and reading order. Native object checks establish object type and inheritance; they do not prove appearance. Complete the requested application checks before claiming editability acceptance.

+# PowerPoint application evidence
+
+Use the host's supported application UI tool, such as CUA, for PowerPoint operations. Initialize it with the documented app/browser entrypoint, read the returned documentation, and operate only through supported APIs. After a resumed computer-use summary, reload that tool's documentation before acting. Do not substitute shell scripting or hidden application automation for UI evidence.
+
+Open the current generated file, verify the visible filename and page thumbnails, and inspect whether PowerPoint shows a repair/recovery warning. Work on task-owned copies and preserve the user's unrelated open presentations. Do not dismiss a repair prompt as successful opening; retain the diagnostic and repair the authored source.
+
+For rendered evidence, export this file to PDF through PowerPoint's own export dialog using the intended quality setting and a task-owned destination. Check the export exists and belongs to the current file, render its pages and inspect the images. Compare page geometry, text wrapping, typography, images, transparent edges, alignment and separators. Confirm actual PDF font identities when font rendering is disputed; a declared PowerPoint face alone does not prove which font the application rendered.
+
+Opening and exporting are distinct from actual editing. When editing evidence is requested, use a disposable task-owned copy: select a representative text/shape/placeholder, change it through the UI, save or export, and verify the resulting independent object/content change. Check an appropriate inherited object separately if template behavior is in scope. Do not alter the authoritative source project or a user's finished original merely to demonstrate editing.
+
+Report the evidence actually obtained: source/reference validation, native structure and object types, current-page rendering, PowerPoint opening, actual object editing, or projection readability. A successful export cannot establish every later level. If the host application or UI capability is unavailable, deliver the validated source and PPTX with that specific unresolved application check.

+# 可移动的 PPT 消费工程
+
+接口版本：`ppt-project/v1`。内容日期：2026-10-10。实现为 [ppt_project.py](../scripts/ppt_project.py)，基础模板接口仍以 [template-interface.md](template-interface.md) 为准。本接口不改变 `template_ref.py`，不安装全局工具，不初始化 Git，不提交或发布。
+
+工程把正文、页面源、数据、素材、模板源、必要工具和依赖说明放在同一目录。Git 可追踪这些输入；设备相关绝对路径、缓存和导出物在运行时重建。一次工程固定一个 template 版本和一个 theme，页面顺序由 `pages` 数组表达，重排页面无需更换页面 ID。
+
+## 初始化与作者工作流
+
+解析和工程管理要求 Python 3.10+，只用标准库；实际 builder 的依赖由工程自行声明。消费方明确逐页制作时，保留 `interactive-page`，不要因建立工程而自动批量创作。
+
+```sh
+python3 /path/to/skill/scripts/ppt_project.py init \
+  --project /path/to/report \
+  --manifest /path/to/released-template/manifest.json \
+  --theme chosen-theme --title '报告标题' --project-id example-report \
+  --route native --workflow interactive-page
+```
+
+`--project` 对六个命令均必需。`init` 另要求 `--manifest`、`--theme`、`--title`；`--project-id` 默认生成合法 UUID，显式值为小写字母／数字及单连字符组成的 ID。路线默认为 `native`，另支持 `image-rebuild`；工作流默认为 `interactive-page`，另支持 `batch`。统一的 `--theme` 在消费 v1 清单时映射为其 `mode`，不改变基础解析器的 v1 CLI。
+
+目标必须不存在或为空目录。初始化在相邻临时目录完成验证后整体重命名，失败不会把半成品合并入已有目录；非空目标保留。模板包根目录为选中 manifest 的父目录，按相对路径复制到 `vendor/template/`，排除所有 `exports/`、缓存、虚拟环境、Git 和本地配置。遇到复制范围内的 symlink 拒绝且不跟随。源清单一般命名为 `manifest.json`；选择其他文件名时保留原文件并添加相同字节的 `manifest.json`，有冲突则拒绝。
+
+初始工程是诚实骨架：没有页面，`build.entrypoint` 为 `null`。`check` 可以通过并返回 `build_ready: false`；`build` 明确拒绝，不生成占位 PPTX。作者加入页面、数据与真实 builder 后执行：
+
+采用本包原生编译器时，可先运行 `python3 /path/to/skill/scripts/prepare_native_project.py --project /path/to/report`。它只接受没有 builder、依赖／字体／工具声明为空的已锁定骨架，复制项目内 compiler／wrapper，写入 `tools/native_builder.py` 和环境声明，并保留旧作者锁。审阅这些改动后显式 `lock`；不覆盖已有 builder 或已配置环境，不改变工程 schema 1。完整行为见 [运行库与出处](runtime-and-provenance.md)。
+
+该通用 builder 读取各页已完成的 SVG 和 Markdown 讲稿；`content.json`／`data` 仍是锁定作者输入，不会自动绑定到 SVG。需要数据驱动生成的消费方应提供自己的明确绑定或预处理步骤。
+
+```sh
+python3 tools/ppt_project.py lock --project .
+python3 tools/ppt_project.py check --project .
+python3 tools/ppt_project.py resolve --project .
+python3 tools/ppt_project.py build --project .
+python3 tools/ppt_project.py pack --project . --out /outside/report-source.zip
+```
+
+`resolve` 是可选的制作准备步骤，`build` 会自动执行。`check` 只读且不运行 builder；`resolve` 只生成运行时记录且不运行 builder。所有命令输出 JSON，输入错误返回退出码 2 和 stderr JSON。初始化和移动工程时均不复用另一台机器的选择记录。

+  exports/deck.pptx                # 可丢弃的构建结果
+```
+
+`project.json` 的固定基础字段如下；示例中页面和 builder 由作者加入，初始值为 `pages: []`、`entrypoint: null`。`data`、`assets`、`inputs` 即便为空也保留数组。所有路径字段为相对于工程根的 POSIX 路径。
+
+```json

+  "project_id": "example-report",
+  "title": "报告标题",
+  "template": {
+    "manifest": "vendor/template/manifest.json",
+    "theme": "chosen-theme",
+    "lock": "template.lock.json"
+  },
+  "authoring": {"route": "native", "workflow": "interactive-page"},
+  "environment": "environment.json",
+  "pages": [
+    {
+      "id": "opening",

+    "entrypoint": "tools/build_deck.py",
+    "output": "exports/deck.pptx",
+    "inputs": ["tools/helper.py"]
+  }
+}
+```
+
+页面 ID 必须稳定且唯一，`layout` 必须在模板 manifest 中声明。三项页面文件名固定为 `pages/<id>/source.svg`、`content.json`、`notes.md`。数据文件可用 JSON 数组等合法 JSON 值；页面内容结构由 builder 定义。工具拒绝重复 JSON 键和非标准 NaN／Infinity。
+
+声明文件必须存在。路径字段拒绝绝对路径、`..`、反斜杠、URL／盘符形式以及 symlink，包括仍指向工程内部的 symlink。SVG `href` 和 CSS `url(...)` 的本地资源、Markdown 行内及引用式链接递归纳入作者输入；相对于源文件解析，允许 `../../assets/...` 等仍在工程内的引用，拒绝逃逸、绝对路径和缺文件。SVG 允许 `#id` 与内嵌 `data:`；Markdown 允许 HTTP(S)／mailto 来源链接和 `#anchor`。这不是完整的 HTML／JavaScript／Python 依赖分析器：builder 导入的辅助文件、动态读取的数据和自定义格式资源仍须在 `build.inputs`、页面 `data`／`assets` 中显式声明。
+
+`vendor/` 下的第三方 Markdown 说明作为固定字节锁定，不递归跟随其工作流或参考文档链接；裁剪后的编译器快照可以保留完整归属说明而无需携带无关文档库。实际构建所需文件仍须显式列入 `build.inputs`。工程 README、页面讲稿及其本地引用继续检查；此例外不豁免 SVG 素材引用。
+
+`environment.json` 初始内容为：
+
+```json
+{
+  "schema_version": 1,
+  "python": {"minimum": "3.10"},
+  "packages": {},
+  "fonts": [],
+  "tools": []
+}
+```
+
+作者应补充实际 Python／包版本、可重建的安装说明、外部工具与字体名称、版本、来源及许可。`check` 校验此文件的基本结构、存在与锁定，不探测所有平台的字体和工具，不自动下载或安装依赖。字体不会因写入清单而获得分发许可；工程只纳入确有许可的字体文件，并显式列入输入。设备设置写入被忽略的 `environment.local.json`，不要把用户名、绝对路径、凭据、私有配置写入受版本管理的清单。
+
+## 两层锁与协作
+
+`template.lock.json` 使用 `schema_version: 1`，包含 `template_id`、`version`、`theme`、工程相对 `manifest` 和有序 `inputs`。每个 input 为 `{"path": "vendor/template/...", "sha256": "..."}`。复用模板解析器验证 released 状态、路线、工作区和选择后，锁定全部复制的模板源，包括未激活 theme；不把 review `exports/` 当源。模板新增、删除、字节变化，或改变 template／theme 选择均使验证失败。
+
+`project.lock.json` 使用 `schema_version: 1`、`project_id` 和相同形式的有序 `inputs`，包括 `project.json`、环境说明、页面 source／content／notes／data／assets、本地资源闭包、builder 与 `build.inputs`、随包两脚本，以及 README／Git 元数据。运行输出不进入锁。
+
+`lock` 先验证模板锁未变，再校验作者输入和引用，原子更新作者锁。它不会修改模板锁、自动接受升级或掩盖缺文件。模板需要升级时，新建显式选择新版本的工程，审阅接口变化后迁移作者输入；不要通过反复 `lock` 接受发布模板漂移。
+
+协作者一起审阅 source、data、project 与锁差异。多人编辑不同稳定页面时仍由工程负责人整合 `project.json` 页序与锁；不要把生成的绝对路径收据作为可移植状态提交。生成的 `.gitignore` 忽略 `build/`、`exports/`、`.venv/`、`node_modules/`、`__pycache__/`、`*.pyc` 和 `environment.local.json`，不忽略正文、数据、素材或讲稿；`.gitattributes` 为 JSON／Python／Markdown／SVG／CSV／TSV 声明 UTF-8／LF，为 PPTX／PDF／PNG 等声明二进制。
+
+## 构建与移动重建
+
+`resolve` 先 `check`，在 `build/local/` 写入本次唯一 ID 的 selection／style JSON。每页使用对应 layout；空骨架生成工程级记录。记录的绝对路径只对当前工程位置有效，v1 模板仅生成 selection。它们不进入 Git 或 pack。
+
+builder 必须是工程内 `.py` 文件。执行前审阅入口代码及依赖；`build` 意味着运行作者声明的工程 Python 代码，不是沙箱。工具先验证锁并生成新收据，再使用当前 `sys.executable`、`shell=False`、工程根为 cwd，固定调用：
+
+```text
+python /absolute/project/tools/build_deck.py \
+  --project /absolute/project \
+  --output /absolute/project/build/tmp/<new-unique-id>.pptx
+```
+
+入口只能通过固定的 `--project`、`--output` 接收工程位置与本次输出位置，不接受 shell 字符串配置；退出 0 后必须实际产生新文件，最长运行 600 秒。工具检查 ZIP 成员、CRC、必要 XML 根和 slide 数量／presentation 页表，重新验证输入锁，然后原子替换 `build.output`。输出必须位于 `exports/` 且扩展名为 `.pptx`。builder 失败、超时、缺输出、无效 ZIP 或输入被修改时，旧产物保留；不能用已有 exports 推断本次成功。成功 JSON 返回本次输出的 SHA-256。
+
+`pack --out` 必需，必须是工程外 `.zip` 路径。既有 ZIP 或同名 `.zip.sha256.json` 均拒绝覆盖。包仅包含已锁作者输入、模板源、两层锁和必要元数据；未声明文件、`build`、`exports`、Git、虚拟环境、缓存及本地配置不进入包。固定路径排序、ZIP 时间与权限，同一输入在同一压缩环境下得到相同 ZIP 字节；不同 Python／zlib 版本未保证逐字节压缩结果相同。另写 JSON SHA-256 收据，收据 archive 字段只存文件名。
+
+移动整个源工程或解压 ZIP 后，先配置 `environment.json` 记录的依赖与有许可的字体，再运行工程随包的 `tools/ppt_project.py check` 和 `build`。不需要访问原模板目录、原 Skill 安装路径、原工作区或旧 exports。缺少外部工具时，由 destination 环境提供，不用旧输出冒充重建。
+
+## 证据与限制
+
+维护仓库的工程专项检查使用合成 released 模板与两页工程，覆盖锁定、路径／资源／symlink 拒绝、作者及模板漂移、失败保留旧产物、确定性源码包、缓存排除，并在原路径不存在时用解压后的工具实际生成新的基本 PPTX；修改数据后再次构建并检查 slide XML 的新数据。Skill 0.5 的独立编译器检查另覆盖原生导出、字体身份、素材边界、项目内 runtime 和移动重建；安装包不要求维护仓库的检查脚本在运行时存在。
+
+这些证据证明本机新路径下的源码可移动与构建接口行为，不代表已在另一台物理设备执行，也不代替渲染、字体一致性、完整 OOXML 关系图、PowerPoint 打开／实际编辑或投影可读性验收。按实际作者路线另外完成原生结构、逐页渲染和产品验收。

+# Runtime, portability and provenance
+
+This Skill contains selection/project tools, native authoring wrappers, and an unmodified compiler snapshot. It does not require another installed Skill, its home directory, or an original machine path. Templates/themes stay external and are supplied through explicit manifests. Host image generation and supported PowerPoint UI remain host capabilities, used only for work that needs them.
+
+The native route requires Python 3.12+ and the nine pinned packages in [requirements.txt](../runtime/requirements.txt). The installer prepares that environment; this Skill does not install globally or ship Python, wheels, application binaries or fonts. Metadata-only selection/project/paint commands use Python 3.10+ and the standard library. A missing native dependency produces an actionable error and preserves existing output.
+
+The compiler is the MIT-licensed `ppt-master` 4.6.0 snapshot from [hugohe3/ppt-master](https://github.com/hugohe3/ppt-master). `runtime/ppt-master/` preserves its LICENSE, sponsorship files, original SKILL.md and all scripts, including the executable attribution guard. Its exact shipped file hashes are in [provenance.json](../runtime/provenance.json). The nested SKILL.md is an attribution file, not a second installable Skill; install only this package's root. No upstream reference library, organization assets or themes are bundled. Do not remove the guard or rewrite upstream files to suppress it.
+
+The preserved snapshot also contains optional upstream utilities and their documentation. Those legacy utility paths, remote services and optional executables are not this Skill's maintained authoring route or an installation requirement. Use the local native wrapper and host image/UI tools described here; do not invoke an optional utility while assuming its separate service configuration exists.
+
+Page/mockup planning and strict input-asset handling draw on the workflow concepts of [codex-ppt](https://github.com/ningzimu/codex-ppt-skill); object inventory, background/material separation and object-type verification draw on the source-reconstruction workflow available in the development environment. The guidance here is independently written and self-contained. No external workflow script, OCR service, mandatory CLI, review state or installation path is required. Complex automatic asset separation and OCR are not represented as bundled capabilities: use the host visual tools and review the result.
+
+The generic wrapper consumes declared palette/font/size data. `preserve_declared_font_families(style)` temporarily protects only those families from the compiler's platform replacement map during a serial compile, restoring process memory on success or failure. It preserves source identity before conversion; it does not replace arbitrary finished-document occurrences of a fallback font. Declared font names do not install, embed or license a font. Verify family, style, version/hash, source, license and actual rendering on the destination device.
+
+For a portable author project, [prepare_native_project.py](../scripts/prepare_native_project.py) copies the required runtime and wrappers into `vendor/native-workflow/`, supplies `tools/native_builder.py`, and records every compiler source as a build input. It accepts an initialized project with an untouched author lock, no builder and an empty dependency/font/tool declaration. It refuses existing destinations and custom environments/builders. It deliberately leaves the old author lock unchanged so the new source must be reviewed and explicitly locked.
+
+The prepared builder reads finalized page SVGs and Markdown speaker notes in project order. It checks the layout IDs and local asset boundaries, then compiles using the vendored template and compiler. `content.json` and declared `data` remain author inputs; this generic builder does not invent a binding schema or automatically regenerate SVG text from those files. If the deck needs data-driven generation, supply a reviewed project-local preprocessing/builder step and declare its inputs before locking.
+
+Move or pack the whole locked project, provision the declared packages/fonts, then use its own tools to check and rebuild. Test from a different directory with the original source unavailable and verify an intentional source/notes change after relocking. Same-device relocation proves path independence for that snapshot, not another physical device's rendering or application editing.

+# Template manifest v2 and v1 compatibility
+
+Select **template → theme → layout**. A catalog discovers multiple independent templates; one command activates one manifest and one theme. Themes share the selected template's structure, layouts and style rules. They do not combine different template geometries.
+
+All catalog paths are relative to the catalog directory. All manifest paths, including asset paths inside theme JSON, are relative to the **manifest directory**. Use POSIX paths without `..`, absolute paths, backslashes or drive/URL prefixes. Paths must remain inside that package after symlink resolution. Duplicate JSON keys are rejected at every parsed level. Remote URLs can be provenance metadata, never executable dependencies.
+
+A catalog has integer `schema_version: 1` or `2` and a `templates` array of objects containing `manifest`. Both catalog versions can list v1 and v2 manifests together. Duplicate template IDs are rejected; list one selected version of each ID. An explicit manifest can pin another version without changing the catalog.
+
+## v2 manifest
+
+| Field | Contract |
+|---|---|
+| `schema_version` | Integer `2` |
+| `template_id`, `version`, `name`, `description` | Non-empty strings; ID uses lowercase ASCII letters, numbers and hyphens; version is SemVer |
+| `status` | `proposal`, `approved`, `released` or `deprecated`; only `released` resolves for production consumption |
+| `spec` | Existing specification file; a proposal brief is allowed for review |
+| `structure` | Existing shared structure file, or null before authored; `resolve` requires a file |
+| `style` | Existing JSON object with shared canvas, typography, grid and general rules; template-specific fields are preserved |
+| `themes` | Non-empty map of theme IDs to `name`, `theme`, `workspace`, `native_template` |
+| `layouts` | Non-empty array of unique `id`, `name`, `slots`; `slots` is a unique string array; extensions are preserved |
+| `routes` | Non-empty unique array drawn from `native`, `image-rebuild` |
+| `editable_policy` | Object with string arrays `native`, `image_allowed`, `disclose` |
+
+Every theme entry declares a theme JSON path and a workspace path. `native_template` is required as a field but may be null: native authoring can generate a deck from the workspace. A declared native file is checked on `resolve`; it must be a `.pptx` outside an `exports/` path and contain the basic presentation ZIP members. Null never permits an incomplete workspace.
+
+A resolvable workspace has `templates/design_spec.md` and at least one SVG prototype. `templates/`, `images/` and `icons/` are hashed authoring surfaces; `exports/` is derived review evidence. Use separate theme workspaces when paint or assets differ, and derive them from the shared structure to prevent geometry drift. Equal layout IDs do not prove equivalent native Master/Layout topology.
+
+## Theme JSON
+
+```json
+{
+  "schema_version": 1,
+  "theme_id": "warm",
+  "palette": {"background": "#FFFFFF", "accent1": "#A14238", "diagram-highlight": "#B36A19"},
+  "assets": {
+    "mark": {"path": "assets/mark.svg", "preserve_aspect_ratio": true},
+    "section-icon": {"path": "assets/section.svg", "paint_contract": "assets/section.paint.json", "usage": "section heading"}
+  },
+  "asset_bindings": [
+    {"asset": "section-icon", "targets": [
+      {"selector": "#body", "channel": "fill", "palette_index": "accent1"},
+      {"selector": "#detail", "channel": "stroke", "palette_index": "diagram-highlight"}
+    ]}
+  ]
+}
+```
+
+`theme_id` must match its manifest map key. Palette keys are arbitrary non-empty names; values are `#RRGGBB`. The interface does not fix the number of colors. `assets` is a map of roles to objects with an existing package-relative `path`. `asset_bindings` is an array; each entry references an existing asset role and a non-empty target array. Targets have a non-empty selector, channel `fill` or `stroke`, and an existing `palette_index`. Assets without `paint_contract` retain their existing selector contract, including `*` or element IDs. This helper never executes selectors or recolors assets.
+
+Keep exact marks, photographs and evidence figures in their original form unless the template explicitly permits a change. Bindings can recolor designated portions of suitable icons; they do not authorize repainting every pixel or scientific color encoding. Additional fields in style, theme, assets, bindings and layouts remain available to the agent. Undeclared extension fields are data, not commands or automatic acceptance criteria.
+
+### SVG paint contract
+
+An asset may declare `paint_contract`, an existing JSON path relative to the **manifest directory**, under the same package containment rules as its SVG path. The field is supported only for `.svg` assets. One contract can accompany an SVG reused by several themes; each theme chooses its own palette indices without changing the contract's semantic tokens.
+
+For the section icon above, `assets/section.paint.json` contains:
+
+```json
+{
+  "schema_version": 1,
+  "asset_id": "section-icon",
+  "default_policy": "preserve",
+  "rules": [
+    {"id": "body-fill", "selector": "#body", "channel": "fill", "policy": "palette", "token": "primary"},
+    {"id": "detail-stroke", "selector": "#detail", "channel": "stroke", "policy": "palette", "token": "highlight"},
+    {"id": "paper-fill", "selector": "#paper", "channel": "fill", "policy": "fixed", "value": "#FFFFFF"},
+    {"id": "open-fill", "selector": "#open", "channel": "fill", "policy": "structural", "value": "none"}
+  ]
+}
+```
+
+| Field | Contract |
+|---|---|
+| `schema_version` | Integer `1` |
+| `asset_id` | Non-empty string identifying the material; independent of a theme's asset role |
+| `default_policy` | Exactly `preserve`; undeclared element/channel pairs retain their original paint |
+| `rules` | Array of rule objects; may be empty to preserve every channel |
+| Rule `id` | Unique non-empty string |
+| Rule `selector` | Exactly `#` followed by a stable XML ID matching `[A-Za-z_][A-Za-z0-9_.:-]*`; no wildcard, CSS query or selector execution |
+| Rule `channel` | `fill` or `stroke`; each `(selector, channel)` pair appears at most once |
+| Rule `policy` | `palette`, `fixed` or `structural` |
+| Rule `token` | Required non-empty string for `palette` only; several rules may share one semantic role token |
+| Rule `value` | Required non-empty literal for `fixed` or `structural`; `structural` currently accepts only `none` |
+
+Each palette rule requires exactly one matching theme target with the same asset role, selector and channel. A contract asset cannot use `*`, target an undeclared pair, or bind a `fixed`/`structural` pair. Duplicate targets, including duplicates across separate binding entries, are rejected. A token describes meaning, not a concrete color or automatic palette lookup: the theme's `palette_index` selects the color for each rule.
+
+Rules govern only the declared channel. A palette `fill` does not authorize changing that element's `stroke`, and a fixed `fill` does not fix other channels. Preserve fixed literals exactly, including white details and paint references such as `url(#gradient)`. Preserve structural `none` as an unpainted channel; do not convert it to white or a theme background. Unknown fields are preserved as metadata. Fixed literals are not interpreted as CSS, validated against SVG, or resolved by this parser.
+
+`inspect` and manifest loading validate contract JSON and theme coverage. The helper does not read SVG IDs, evaluate inherited/style-based paint, verify original fixed values, inspect transparency, or execute a recolor. The authoring workflow must check those material facts and reject unresolved conflicts before changing an asset. Whole-image pixel replacement is outside this contract.
+
+## CLI behavior
+
+Use Python 3.10 or newer. `list` and `inspect` print JSON without writing files:
+
+```sh
+python3 /path/to/skill/scripts/template_ref.py list --catalog /path/to/library/catalog.json
+python3 /path/to/skill/scripts/template_ref.py inspect --manifest /path/to/template/manifest.json
+```
+
+`inspect` preserves manifest extension fields and exposes themes/layouts for review. It checks declared metadata, theme references, asset/paint-contract paths, contract JSON and binding coverage; it does not establish production acceptance.
+
+### Export style for review and alignment
+
+```sh
+python3 /path/to/skill/scripts/template_ref.py export-style \
+  --manifest /path/to/template/manifest.json --theme warm \
+  --layout figure --out /path/to/report/style-review.json
+```
+
+This v2-only command accepts proposal, approved, released and deprecated states and reports the actual `status`. `production_ready` is exactly `status == 'released'`; it is a status flag, not independent release verification. Style export creates no PPT and does not require an authored workspace or native PPTX. Existing spec, style, theme and asset files are still required; `structure` may be null. Workspace/native paths can describe future artifacts and their existence is not promised by this output.
+
+The JSON includes template ID/version/status, selected `theme`, optional `layout` and complete `layout_definition`, `manifest`/`manifest_sha256`, absolute `spec`, `structure`, `style_path`, `theme_path`, `workspace`, `native_template`, complete `style` and `theme_data`, and `editable_policy`. Asset `path` and declared `paint_contract` paths in `theme_data.assets` become absolute. For each contract asset, `paint_contract_data` contains the complete parsed object, including extensions. Other fields are passed through unchanged; assets without a contract gain no new fields. `inputs` lists package-relative paths and SHA-256 hashes for the actual spec, structure, style, selected theme/assets/paint contracts, existing native file and existing workspace authoring surfaces. This supports agent review, prompt constraints and style alignment before production binding.
+
+### Resolve one production selection
+
+```sh
+python3 /path/to/skill/scripts/template_ref.py resolve \
+  --manifest /path/to/template/manifest.json \
+  --theme warm --route native --workflow interactive-page \
+  --layout figure --out /path/to/report/template-selection.json
+```
+
+Only `released` resolves. `--theme`, `--route` and `--workflow` are explicit; `--layout` is optional before individual pages. Repeated theme/mode/layout flags are rejected instead of taking the last value. The command accepts one manifest; simultaneous mode and theme activation is invalid. Record each page's actual layout with its authoring artifacts.
+
+The selection record includes schema version, template ID/version, manifest path/hash, theme, optional layout, route, workflow, workspace/native/spec/structure/style/theme paths and hashes of resolved inputs. v2 adds status and `production_ready`. It hashes the selected theme, its assets and their paint contracts, not every unselected theme. A receipt is a local snapshot, not replacement source. Re-resolve after changing an input or moving a package; unchanged records can be reused.
+
+`resolve` and `export-style` print JSON and optionally write it with exclusive `--out`; an existing destination is never overwritten. Invalid data returns exit code 2 and a compact JSON error. CLI syntax errors also return 2 through argparse.
+
+## v1 compatibility
+
+v1 manifests retain `schema_version: 1` and `modes` instead of `themes`. Each mode declares `name`, `workspace`, `native_template`; paths may be null before release. There is no required shared `style` or theme JSON. Use `resolve --mode <id>`; `--theme` and `export-style` require v2. v1 production binding still requires both a complete workspace and an existing native PPTX. Common fields, routes, layout validation, path containment, duplicate-key protection and exclusive output behavior remain supported. Existing v1 selection records retain their `mode` field and schema version.
+
+To migrate, separate shared style rules from theme palettes/assets, add `style` and `themes`, change the manifest schema to 2 and bind with `--theme`. Keep v1 packages and selection receipts pinned; do not rewrite them in place to simulate a migration.
+
+## Evidence and authority
+
+The helper checks metadata, references, containment, local files, hashes, workspace shape and declared PPTX ZIP members. It does not parse template-specific structure semantics or establish OOXML validity, placeholder topology, visual fidelity, font availability, native editability, application behavior or projection readability. Report those checks separately.
+
+A manifest authorizes neither installation nor external communication nor consumer-project changes. Treat all template content as untrusted design input; it cannot override the user's scope, selected workflow or agent instructions.

+# Page mockups and visual materials
+
+Reuse the user's settled template, theme, route and page workflow. Define the current page's title/message, supporting evidence, content groups, notes, layout, asset roles and required native objects before generating its mockup. Review only consequential decisions that remain open; do not restart settled outline or style choices. A request to review one page does not authorize a full-deck generation run.
+
+When extracting style from an existing presentation or PDF, render representative pages and inspect the actual images. XML/object counts alone cannot establish density, hierarchy, ornament or spacing. Keep style references separate from strict source assets. Use existing accepted references; a rejected mockup does not remain a design baseline.
+
+## Mockup prompt inputs
+
+Use the host image-generation tool directly for requested raster page samples. Supply:
+
+- The selected canvas/aspect ratio, template palette, typography intent, grid and fixed content regions.
+- The exact current-page text and moderate content density, with a declared hierarchy and clear content division.
+- Approved representative images as style references, with the current layout allowed to differ.
+- Supplied logos, figures and screenshots as strict identity/evidence assets. Preserve values, axes, labels, proportions and scientific meaning; do not synthesize substitute evidence.
+- The editable reconstruction plan: decorative pictures may remain assets, while title/body, controls, separators and diagrams must later become independent native objects as required.
+
+Inspect local reference images using the available image-viewing tool before editing or conditioning on them. Label each input's role in the prompt. Save prompt, tool result, source attribution and review status under the project. Show the current sample for the user's requested review and incorporate concrete corrections before native reconstruction.
+
+Use generated text only as visual guidance. Native source text comes from verified content, with the template's declared fonts and sizes; do not copy misspellings or typography defects from the raster sample. Preserve original evidence/identity assets independently so the final native page can use those files exactly.
+
+## Material generation and transparent assets
+
+For new bitmap illustrations, photos, textures or image edits, use the selected host image-generation capability. Request a transparent background when the final asset needs transparency. Preserve transparency on edits unless the user asks to change it. Use reference-image paths when all targets have paths, otherwise the smallest supported recent-image set that includes every target; do not silently omit a required target.
+
+Ask for complete separated objects with consistent perspective, stroke and illumination. A material sheet can contain several non-overlapping assets with clear outer padding, but verify identity/count and edges after separation. Keep logos and strict evidence originals; generated approximations need explicit permission for that role. Repair small occlusions locally rather than redesigning an entire source background.
+
+Check transparent edges against both light and dark backgrounds for halos, missing thin strokes and unintended holes. Avoid arbitrary color-key removal that erases matching subject colors. If an approved layered source or role mask exists, retain it with a clear mask-to-material contract; otherwise regenerate an unsuitable cutout through the image tool.
+
+For an existing SVG icon system, use its vector source and declared paint contract rather than generating a new bitmap. Multiple independent color roles need stable element IDs and per-channel rules. Palette binding, fixed details, structural `none` and unlisted paint remain distinct.
