T-8K2M-converge-sdf-desktop-frontmatter-reader

Status: closed/done · Impact: low · Complexity: small

Goal

Section titled “Goal”

Converge the sdf desktop app’s own frontmatter splitter — apps/sdlc/desktop/src-tauri/src/control_plane/frontmatter.rs (extract_frontmatter / parse_task_frontmatter) — onto the shared markdown-util (M-6TQL). It is the last in-tree Rust splitter still carrying its own fence logic; it reads a task file’s status/headline for the stale_inflight dashboard warning.

It was deferred because its fence recognition mirrors frontmatter.ts’s ^---\s*\n … \n---\s* — trailing whitespace on the fence lines is tolerated. Converging onto strict split drops that; converging onto split_lenient (shipped with M-6TQL) keeps it and also adds leading-whitespace tolerance the TypeScript arm lacks. Either way the fleet’s fence-whitespace behaviour is being decided, so this is blocked on the dialect ruling in D-4QGN-markdown-dialect-and-compatibility-profile, coordinated with M-D3KP-typescript-frontmatter-on-markdown-util. Real task files are machine-written with clean ---\n fences, so the practical change is nil — the decision, not the blast radius, is the gate.

Acceptance criteria

Section titled “Acceptance criteria”
  • The sdf reader delegates fence detection to markdown_util::split_lenient (or split, per the dialect ruling) and deletes its bespoke scan.
  • status/headline extraction and status_group are unchanged; the stale_inflight warning behaves identically on the real task corpus.
  • A before/after fixture records any intended change from the ruling.
