Axismundi Table of Contents

Axismundi Table of Contents provides the axismundi/toc block: a dynamic, server-rendered list built from the current post's headings, with a scroll-spy that marks the section you are reading. The block render and a render_block_core/post-content filter share one deterministic slug function, so the table-of-contents anchors always match the heading ids — regardless of render order or where you place the block (a template aside or inside the content). Author-provided HTML anchors are respected, and duplicate headings are de-duplicated (-2, -3).

• Two placements: a sidebar rail, or a collapsible disclosure above the content (a native <details> whose summary can echo the current section). A "Table of contents (above content)" pattern ships the disclosure ready to drop before the post content.
• Builds from h2–h4 by default (configurable per block).
• Unordered list by default; switch to a numbered (ordered) list per block.
• Emits the shared toc-list / toc-h2…h4 / is-current class vocabulary so a theme's table-of-contents skin couples for free; ships a Material Design 3 token skin (with fallbacks) in the meantime.
• Scroll-spy marks the current heading and clears when you leave the content (above the first heading or past the post content).

0.1.2

• Let the host theme or template control disclosure placement and sticky behavior so the block remains layout-neutral in the editor.

0.1.1

• Prepare the package for WordPress.org Plugin Check by removing the hidden distribution manifest and relying on WordPress.org translation loading.

0.1.0

• Initial release: the axismundi/toc block (server-rendered list from post headings) with deterministic, shared heading-id slugs and is-current scroll-spy.
• IntersectionObserver plus an rAF scroll fallback decide the active section from one rule; the active state clears when the reading position leaves the content.
• Material Design 3 token skin (with fallbacks) over the shared toc-list / is-current vocabulary; smooth in-page scrolling is owned by the theme.
• Rail and disclosure placements. The disclosure is a native <details>; placement and sticky behavior are controlled by the host theme or template. Open-by-default and summary mode are per-block, and its summary can track the current section. Ships a "Table of contents (above content)" pattern.
