`graft` mirrors comments on issues and patches, both directions, from four origins:
220
220
221
-
- **Forgejo → Radicle** and **Radicle → Forgejo**: native comments, polled and cross-mirrored each pass. Dedup is by content hash (`comment_seen` table) plus a `**via Forgejo:**` / `**via Radicle:**` prefix on the mirrored copy, so a mirrored comment is never mirrored back.
222
-
- **ActivityPub**: a Mastodon reply to one of graft's posts becomes a comment, prefixed `**via Fediverse, @user:**`.

- **Forgejo → Radicle** and **Radicle → Forgejo**: native comments, polled and cross-mirrored each pass. Dedup is by content hash (`comment_seen` table); the mirrored copy is visibly prefixed `**via Forgejo:**` / `**via Radicle:**` for readers, but the actual loop guard is an invisible marker (zero-width characters, `state.MarkMirrored`/`IsMirroredComment`) appended to the body — a real comment that happens to start with the same visible text is never mistaken for one of graft's own mirrors.

- **ActivityPub**: a Mastodon reply to one of graft's posts becomes a comment, prefixed `**via Fediverse, @user:**` (same invisible marker).
223
223
- **AT Proto**: a Bluesky reply, same mechanism, prefixed `**via Bluesky, @handle:**`. Not verified against a live account — built from AT Proto's published lexicon (`app.bsky.notification.listNotifications`), but no Bluesky account existed to test against when this was written.

Dashboard cells are colored by kind only (commit, issue, patch, comment) — never by origin. Origin shows up as a tooltip note only, on hover.
