Part 1 of item #28: references to existing accepted RFCs inside PR
descriptions and comment text now render as inline links to the
referenced RFC. Parts 2 (offer-to-create) and 3 (offer-to-contribute-
to-pending) are deliberately deferred — Part 1 ships first as the easy
win, per the roadmap row.
Shipped in parallel with the v0.25.0 security-hardening session; this
took the next free version slot (0.26.0) per the roadmap's
"claims the next available version number" rule. Expect a top-of-file
CHANGELOG/VERSION merge with 0.25.0 — distinct concerns, trivial to
resolve.
Backend:
- rfc_links.py (new): builds a term index from the live accepted
(state='active') RFC corpus and segments plain text into text /
rfc-link segments. Conservative matching — links only rfc_id tokens
(RFC-0001), multi-word titles (Open Human Model), and hyphenated
slugs (open-human-model); a single common-word title/slug is NOT
linked (would turn every prose "human" into a link). Case-insensitive,
word-boundary-anchored, longest-match-wins, self-reference suppressed.
- api_prs.py get_pr(): enriches the PR description (description_segments)
and every PR comment (text_segments).
- api_discussion.py: enriches PR-less discussion comments (text_segments).
Read-time, not submit-time: the roadmap says "at submit time" but the
intent it names is "not as live compose preview", which read-time
honors. Chosen for correctness (links track the live active set —
newly-accepted RFCs start linking, withdrawn ones stop), zero migration,
and cheapness (small cache-resident corpus). Recorded as a §19.3-rule-2
note in the session transcript.
Frontend:
- LinkedText.jsx (new): maps backend segments onto React text nodes +
anchors. No dangerouslySetInnerHTML — XSS-safe by construction,
independent of any HTML-sanitization layer. Falls back to raw text
when segments are absent.
- PRView.jsx: description + PR conversation comment bodies render via
LinkedText.
- RFCDiscussionPanel.jsx: discussion comment bodies render via LinkedText.
- App.css: .rfc-autolink (subtle accent + dotted underline, tokenized).
Tests: 12 new (test_rfc_links_vertical.py) — 9 scanner units + 3
end-to-end (PR description / review comment / discussion comment all
surface *_segments; self-reference suppression). Full suite 363 green;
frontend builds clean.
No upgrade steps: additive, no migration, no secret, no config.
