Index Pure Rewrite

The pure Index rewrite is split into four source modules:

• apps.index.document-model: semantic document records, source metadata,

headings, links, citations, sections, text blocks, action hints, and stable

text/JSON rendering.

• apps.index.extractors: HTML, Markdown, feed-shaped input, link, markdown,

JSON, citation, section, and malformed-input diagnostics.

• apps.index.render: plain/profile rendering, TUI command parsing, and stable

command output records.

• apps.index.policy-tools: compatibility pack, auth assist, challenge, IDX,

and adapter policy logic against fake state.

These modules are pure. Runtime-backed file, HTTP, browser, and process behavior

is attached only by later Index runtime milestones.
