## Summary The server clamps `/api/nodes` `?limit` to **500** (DoS guard, PR #1540 / v3.8.3) and orders by `last_seen DESC`. Every node-list consumer issued a single big-`?limit` fetch and trusted it as the full set, so on >500-node meshes the top-500-by-advert window silently hid the tail. Because `nodes.last_seen` is updated **only on self-adverts** (never on relay traffic; `UpsertNode` is called solely from the advert path), a repeater that relays constantly but last advertised hours ago fell outside that window and **vanished from the map and live view** — while still showing "Active" in its detail panel and (since #1606) in the paginated Nodes list. #1606 fixed only the Nodes page (`nodes.js`). This generalizes that fix to the deferred siblings. ## Changes - **`public/app.js`** — new shared `fetchAllNodes(extraQuery, opts)`: pages `limit=500` + `offset` until a short page (the server's `total` is unreliable — clamped to the page size and overwritten with the filtered length under area/region filters, so we stop on a short page, not on `total`), dedups by `public_key`, returns the real deduped count as `total`. - **`public/map.js`**, **`public/live.js`** (keeps the `LIVE_MAP_MAX_NODES` ceiling via `safetyCap`), **`public/analytics.js`** (×2), **`public/packets.js`** now use the helper. - **`public/area-map.html`** is standalone (cross-origin `baseUrl`, no `app.js`) so it gets an inline copy of the same loop. - **`.eslintrc.json`** — declare `fetchAllNodes` global (no-undef). ## Tests - **`test-fetch-all-nodes-pagination.js`** — unit-tests the helper via the real `api()`+`fetch` path: pagination past 500, short-page stop vs. the unreliable server `total`, dedup across a page boundary, counts pass-through, `safetyCap` bound. 5/5. - **`test-map-nodes-pagination-e2e.js`** — browser E2E (Playwright) proving `map.js` surfaces a 501st node reachable only on page 2 and renders its marker. Verified **red→green**: against the pre-fix single fetch all 3 assertions fail (500 nodes, page-2 node absent, no marker); after the fix all pass. Wired into `deploy.yml`. ## Verification - unit 5/5, E2E 3/3, `test-frontend-helpers.js` 611/611, `npx eslint public/*.js` → 0 errors. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
