+## execution plan
+
+1. `gigs/are-na-annual-vol-8/swap-sources.mjs` — read approved swaps, for each: delete old block from channel, post new URL with same description
+2. keep positions stable — post in reverse reading order so nothing rearranges
+3. text blocks (§9 framing, §6 Ono quote) are untouched — they're already primary
+
+## what the `nearby` validator can't tell us without a token
+
+are.na's `/v2/search/blocks` requires auth. once `ARENA_TOKEN` is exported, re-run `node validate-sources.mjs` and it will surface which URLs already have dozens of connections on are.na — those are the de-facto primaries.
