# Htmx Foundation

> Use when porting or embedding a hypermedia-driven AJAX/DOM kernel: attribute-inheritance ladder, trigger-spec grammar and dispatch FSM, extended selector engine, priority FormData collection with live proxy, request lifecycle with hx-sync queueing, response-handling table with HX-* control headers, swap/settle choreography with OOB + preserve pantry, hash-gated node processing, history cache LRU, boost/security gates.

# htmx: Hypermedia Interaction Kernel Foundation

## Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is
historical, revision-pinned evidence rather than timeless guidance. Current
project source, tests, requirements, and runtime behavior outrank this
projection and decide what ships.

## Provenance and revision

- Source record: `htmx`; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
- Recorded revision: `master@ad56dff71e55d9c717447437b4c942a64575d4b2`.
- Full provenance, coverage caveats, boundaries, and preserved evidence:
  `references/index.md`.

## Topic map

- Representative topics: Attribute semantics; Parsing plane; Trigger runtime;
  Data plane; Request plane; Response & swap; Lifecycle & infra.
- Scope and retrieval questions: `references/index.md#use-this-for`.
- Complete capsule chooser: `references/index.md#load-the-matching-source-dump`.
- Detailed grouped map: `references/index.md#capsule-map`.
- Source limitations and portability boundaries: `references/index.md#boundaries`.

## Retrieval

Open the index, choose one capsule matching the active question, and load only
that capsule. Revalidate its cited source and revision before relying on it. Do
not bulk-load the inventory, treat historical claims as current truth, or apply
this foundation as a procedure.
