// compose-org-profile.mjs
// Purpose: wrap the NESTED org-profile YAML body (organisasjon:/program: ...,
// read from stdin) in an OKF-compatible frontmatter document, prepending the
// three top-level OKF keys the second-brain "Documents/kb" layout expects on a
// concept file: type / resource / timestamp. Emits the full document to stdout,
// meant to be piped into write-org-profile.mjs (which writes it atomically to
// the reinstall-surviving home path ~/.claude/okr/org/profil.md).
//
// Why a dedicated composer (not lib/frontmatter.mjs writeFrontmatter): the org
// profile is NESTED (organisasjon: { navn, type }, program: { ... }). The flat
// writeFrontmatter would flatten/destroy that structure. We instead keep the
// caller's nested YAML verbatim and only PREPEND OKF keys above it.
//
// Why ONLY type/resource/timestamp top-level: the home profile is read by the
// flat parser (lib/frontmatter.mjs) in inject-okr-context.mjs via
// get('navn')/get('id')/get('domene')/... A NEW top-level key colliding with
// any of those (navn/name/id/fase/domene/sektor) would be matched FIRST and
// shadow the nested value, breaking org/cycle resolution (the Critical risk).
// type/resource/timestamp are read by NO consumer, so they are safe to prepend.
// The nested organisasjon.type ("offentlig") is untouched and still unread.
//
// Single-block invariant: the OKF keys and the nested body MUST live in ONE
// frontmatter block. A stray intermediate '---' would truncate the block the
// flat parser reads (dropping organisasjon: -> get('navn') === null -> no
// injection), so any fences the caller already put around the body are stripped
// before re-wrapping.
//
// Testable clock seam: OKR_NOW (ISO-8601) overrides the wall clock so the
// emitted timestamp is deterministic under test.
//
// Zero npm dependencies (node: builtins only). ASCII-clean identifiers.
