Context: DRAFT pins Rust + minimal deps but names are unconfirmed. Time-boxed spike before any render code.
Tasks:
- Spike `pulldown-cmark 0.13.4` on f0rge fixtures (issue.md, pr.md, wiki page): markdown->HTML, confirm escaping of `<script>`.
- Spike frontmatter: tiny `---` split + `serde_yaml` on real `.forge/issues/<uuid>/issue.md` files (borrow ../f0rge/.forge). Confirm unknown-field tolerance + missing-field error naming file+field.
- Confirm RFC3339 parse approach (chrono vs hand-rolled) and JSON via serde_json.
- Output: `docs/deps-decision.md` (or wiki note) locking versions + fallback if a crate is rejected.
Success rubric:
- [ ] Decision doc exists with pinned versions + why, deps total <= 5.
- [ ] Spike parses 20+ real f0rge fixture files with 0 panics; malformed file yields named error.
- [ ] No tokio/hyper needed: confirmed std-only path for later inbox work.
Swarm: one Owlette/Owl, read-only, no repo code changes except decision doc.
