//! §4 "Presets" (`docs/composable-harness/COMPOSABLE-HARNESS-DESIGN.md`) —
//! P2 of the composable-harness migration (design §5.2, phase **P2**).
//!
//! The six reserved built-in presets, compiled in as TOML consts, transcribed
//! faithfully from the design doc's §4.1-§4.5 TOML blocks (and §4's intro
//! paragraph for the sixth, `supercode-default`, which the doc defines by
//! prose rather than a TOML block — S10 fix: "`pi-core` MINUS `{trust,
//! session_tree, session_share, server, plugins}`", not "`pi-core` plus
//! extras").
//!
//! **Syntax fix (P2 judgment call).** The design doc's `[capabilities.X]
//! { enabled = true, ... }` lines combine a TOML table-HEADER and an
//! inline-table VALUE on one line, which is not valid TOML (verified
//! empirically against the `toml` crate: `invalid table header, expected
//! newline`). Naively rewriting them as dotted-key assignments
//! (`capabilities.X = { ... }`) is also unsafe wherever such a line appears
//! *after* an already-open `[capabilities.permissions]` table (cc-parity,
//! cx-parity, oc-parity all have this): a dotted key inside an open table is
//! relative to the CURRENT table, so `capabilities.permissions.sandbox = {..}`
//! written while inside `[capabilities.permissions]` nests as
//! `capabilities.permissions.capabilities.permissions.sandbox`, silently
//! corrupting the structure. The transcription below instead expands every
//! `[capabilities.X] { k = v, ... }` shorthand into the equivalent explicit
//! form — a real `[capabilities.X]` table header (always root-absolute,
//! never context-relative) followed by `k = v` lines — which is safe
//! regardless of surrounding context and preserves the exact same resolved
//! structure. Every block below is verified to parse into `HarnessConfig`
//! in this module's tests, and each preset's resolved shape is golden-tested
//! against §4.6's per-preset verdicts in
//! `crates/harness/tests/composable_presets.rs`.
//!
//! Comments from the design doc are preserved verbatim inside each TOML
//! block for traceability back to the source section.
