// c31 — model: /goal slash-command registry. Each /goal that drove a
// PR on this site lives as a markdown file in goals/<slug>.md with
// YAML frontmatter, and this registry indexes them so /goals,
// /goals/:slug, and the sitemap have a single source of truth.
//
// FILENAME CONVENTION: every goal file is named goals/<slug>.md, NOT
// goals/<sha>.md. The merge SHA is in the frontmatter as merge_sha:
// — looked up via b32_goals_meta.findGoalByMergeSha. Rationale: the
// SHA doesn't exist when the /goal is written (chicken-and-egg), and
// /goals/<slug> is a more readable canonical permalink. SHA lookup
// still works in one grep: `grep -l "merge_sha: 968890f" goals/`.
// See /blog/2026-05/sama-v2-goal-chain-gap for the design rationale.

// Five-status taxonomy:
//   pending   — in-flight; mergeSha/prNumber null; file exists on the branch
//   shipped   — verbatim /goal text recovered from PR body/conversation; file exists
//   lossy     — paraphrased recovery (e.g. from conversation summary); file exists
//                with a "recovered from conversation summary, not verbatim" banner
//   lost      — no recoverable source; registry entry only, NO file on disk;
//                /goals/<slug> renders metadata-only at 200
//   abandoned — PR closed without merging
