1//! # Module: lib (agent_doc)
2//!
3//! ## Spec
4//! - Exposes the public API surface consumed by the CLI binary, FFI layer, and editor plugins.
5//! - Re-exports: `component`, `crdt`, `debounce`, `ffi`, `frontmatter`, `merge`, `template`.
6//! - `component::strip_comments(content)` is the shared entry point for comment stripping,
7//!   usable by both the binary (`diff::compute`) and external crates (`eval-runner`).
8//! - Provides two boundary-ID utilities used across all write paths:
9//!   - `new_boundary_id()` — 8-hex-char UUID v4 prefix (length controlled by `BOUNDARY_ID_LEN`).
10//!   - `new_boundary_id_with_summary(summary)` — same ID optionally suffixed with a 3-word,
11//!     20-char-max slug derived from `summary` (format: `a0cfeb34:boundary-fix`).
12//! - `format_boundary_marker(id)` — renders the canonical HTML comment form
13//!   `<!-- agent:boundary:<id> -->` used in document component boundaries.
14//! - `BOUNDARY_ID_LEN = 8` is a public constant; callers may read but should not override.
15//!
16//! ## Agentic Contracts
17//! - All public symbols are safe to call from FFI consumers (JNA, napi-rs) via `ffi` module.
18//! - `new_boundary_id` is non-deterministic (UUID v4); callers must not rely on ordering.
19//! - `new_boundary_id_with_summary(None)` and `new_boundary_id_with_summary(Some(""))` both
20//!   return a plain 8-char ID with no suffix.
21//! - Slug derivation: lowercase, non-alphanumeric chars → `-`, collapse runs, take first 3 words,
22//!   truncate to 20 chars.
23//!
24//! ## Evals
25//! - new_boundary_id_len: result is exactly `BOUNDARY_ID_LEN` chars of hex
26//! - new_boundary_id_with_summary_none: `None` summary → plain 8-char hex
27//! - new_boundary_id_with_summary_empty: `Some("")` → plain 8-char hex
28//! - new_boundary_id_with_summary_slug: `Some("Boundary Fix")` → `"<id>:boundary-fix"`
29//! - new_boundary_id_with_summary_truncate: long summary → slug capped at 20 chars
30//! - format_boundary_marker: `"abc123"` → `"<!-- agent:boundary:abc123 -->"`
