A logfmt formatter for Elixir's Logger

The small runtime support library Ichor-generated parsers call into: capture dispatch, error formatting, compiled Tokenizer/Parser combinators, and the LR/GLR runtime -- plus standalone Pratt precedence parsing, generic term recursion, and unification/backtracking search. Ichor itself is dev-only.

Compiles grammar definitions -- Aether, its own DSL, plus ABNF/EBNF/PEG/BNF importers -- into separated Lexer/Parser/Analysis/Executor modules, with both an interpreted VM backend and a compile-time native codegen backend.

Parses and loads CASC config files -- a hierarchical, extensible config language with imports, variables, interpolation, loops, and consumer-registered resolvers/tags -- into native Elixir terms, secrets redacted by default.

DXN (Data eXchange Notation) for Elixir -- .dxn text, .dxnb binary, and .dxns schema documents, built on the Ichor grammar compiler.

Xeger - generate strings that match a regex-like pattern (regex → strings).

A standalone Prolog-like resolution engine and clause database for Elixir: terms, unification, SLD-resolution, backtracking, a genuine clause-scoped cut, and builtin predicates, built on Ichor's search substrate. No parser -- bring your own front-end (e.g. Aletheia) or build goal terms directly.

A Config.Provider that loads app config from a CASC file (via Cooper) at release boot, replacing Mix's compile-time config.exs/runtime.exs for the settings that need to come from CASC instead.

A Clojure-flavored Lisp, embeddable in Elixir/BEAM applications -- parsed and executed via Ichor, with real tail-call optimization, namespaces/Vars, hygienic syntax-quote macros, and BEAM-native concurrency (spawn/send/receive, atoms).

An embedded Prolog dialect for Elixir: classic Prolog syntax (`:-`, `,`/`;`, `=`, a mutable op/3 table) via a reader on Ichor, fronting Episteme -- the resolution engine and clause database (unification, SLD-resolution, backtracking, a real clause-scoped cut) behind it.

Recurrence rules that read and write both RFC 5545 RRULE and plain English
