Examples below +use Rust's `///` / `//!` and intra-doc-link syntax because +that is the most common case in this user's projects; +substitute the equivalents (TSDoc `/** */`, Python docstrings, +Javadoc `/** */`, etc.) for other languages. + +- **Top-level / crate root** (e.g. `//!` in `src/lib.rs` for + Rust) explains, in this order: what this component is, how + it fits into the project's pipeline, the most important + entry points (with intra-doc links where the doc system + supports them), and the key invariants. +- **Module root** (e.g. `//!` at the top of every module file + for Rust) answers: what does this module own, what does it + not own, what is the typical entry point. +- **Every public item** (struct, enum, fn, type alias, trait, + const, class, interface, etc.) gets a doc comment. One + sentence is fine if the name is self-evident. Two-to-five + sentences when the item carries an invariant, a non-obvious + cost, or a precondition the caller must respect. +- **Use intra-doc links** where the doc system supports them + (Rust: `[Type]`, `[fn_name]`, `[module::item]`). No + prose-only references to types when a link is possible — a + reader should be able to click. +- **Add example sections** sparingly: only where an example + genuinely shortens the path to understanding. If the doc + system runs the examples (Rust doctests, Python doctest), + mark them so they don't have to execute against the full + workspace (`ignore` / `no_run` in Rust). +- **Cross-repo references** (the design ledger, journals, CLI + subcommands) are fine as plain prose mentions — those are + outside the doc-comment universe, so don't try to link them. + +## Hard limits + +- No API changes, no renames, no signature tweaks.
