 ### Added
+- **Read-only task checklists in the Semantic Passport.** Architecture, Workflow, Sequence, Dataflow and Lifecycle nodes may carry an optional `task_checklist` of up to 12 tasks, each `implemented`, `needs-review` or `pending` with optional criteria. Statuses are the author's claim: task sources are verified like node sources, which shows the cited lines exist at the pinned revision but not that a task is done, and an implemented task must cite one. The Passport shows one counted line that expands to the tasks; tasks remain outside canonical SVG and visual exports.
 - **Authored node explanations in the Semantic Passport.** Architecture, Workflow, Sequence, Dataflow and Lifecycle nodes may carry optional plain-text explanations up to1200 characters. Explain opens a viewport-bounded reading face with scrollable prose and a reachable Back action; Escape restores the Passport. Prose remains outside canonical SVG and visual exports, and existing diagram geometry is preserved.
 - **Cross-diagram navigation.** Nodes may list sibling `.html` targets via `drilldowns` or a one-entry `href` shorthand. One child uses a native SVG link and visible mark (click follows, Alt-click focuses). Several children keep click-to-focus, with Passport listing every target and Ctrl/double-click opening the first. Child pages can author `meta.parentHref` for header Back; the Viewer also accepts `?from=`.

 Architecture, Workflow, Sequence, Dataflow and Lifecycle nodes may carry optional plain-text `explanation` (1–1200 characters). The focused Semantic Passport offers Explain; prose stays outside canonical SVG and visual exports. Omit the field when the existing label, sublabel and sources are sufficient.
 
+The same nodes may carry an optional `task_checklist` (1–12 tasks with `title`, `status` and optional `criteria` and `sources`) when the user wants implementation progress on the diagram; the focused Semantic Passport lists it read-only, outside canonical SVG and visual exports. Mark a task `implemented` only when its cited code satisfies the criteria, `needs-review` for partial or unverified work, and `pending` otherwise. Implemented tasks cite at least one source and pending tasks none; task sources are verified like node sources (`meta.repository` and `--repo-root`). Unlike an Explainer task list of reader to-dos, it records the author's claim: verification only shows that each cited file and line exists at the pinned revision, not that the task is implemented.

 Live motion is enabled by default for every rendered diagram; omit `meta.animation`. The Viewer’s Live/Still button controls playback.
