Extension Refactor Task Graph

Date: 2026-05-18

Priority override: finish the cleanup gate in docs/refactor/analysis-3.md before more feature extraction. Cleanliness comes first: EXT-033 through EXT-037 block EXT-021, EXT-022, EXT-023, EXT-031, and EXT-032.

Classification SnapshotURL copied

Kernel:

• Config loading and precedence.
• Extension catalog, plan validation, capability conflict checks, and route mounting.
• Request/render context accessors.
• Declared asset serving and extension static route plumbing.

Default extensions:

• default_layout: document shell and page frame.
• default_theme: theme preset and token loading.
• default_search: index, ranking, sidebar search, and preview cards.
• blog_home: fallback post-card home feed.
• filesystem: local content roots, folder notes, tree projection, and raw path resolution.
• filesystem_routes: raw/download routes.
• markdown: markdown pipeline, processors, and fence dispatch.
• wikilinks, tabs, mermaid, d2, cytograph, cryptograph, tasks: markdown feature adapters.
• slides, annotations, bookmarks, auth_routes, rbac_admin, sidebar_routes: feature route owners.

Kernel exceptions still present:

• core.py still assembles home, search, sidebar, page layout, auth wiring, and document routes.
• layout_page.py is still a kitchen-args page renderer, not a deep PageFrame.
• helpers.py still knows filesystem and content-root policy.
