OGAR shape ([`Class`] / [`ActionDef`]) via passing tests and marks every +//! place a real Elixir parser must plug in with a `todo!()` and a +//! doc-comment naming the exact Elixir construct to read. +//! +//! # The two-arm pattern (per `docs/OPENPROJECT-TRANSCODING.md §10.1`) +//! +//!

See `docs/ELIXIR-HIRO-PREFETCH.md §2` for the full mapping. In short: +//! +//! 1. Add an Elixir parser dep. Recommended: `tree-sitter` + +//! `tree-sitter-elixir`. +//! 2. Replace the `todo!()` in [`parse_modules`] to produce a +//! `Vec`. +//! 3. Replace the `todo!()`s in the per-construct extractors +//! ([`extract_ecto_schemas`], [`extract_gen_server_actions`], +//! [`extract_gen_statem_actions`], [`extract_phoenix_actions`], +//! [`extract_oban_actions`]) to read the Elixir constructs documented +//! on each. +//! 4. Run the locked-shape tests after each step — they assert the OGAR +//! output for hand-built fixtures, so they tell you when your +//! extraction produces the right shape. +//! 5. Point [`extract`] / [`extract_action_defs`] at a real Elixir source +//! tree (e.g., HIRO's `lib/` or Bardioc's `apps/*/lib/`). +//! +//!
