Examples: the proofs read Events by cursor only (no seq) (#19)

OP OpenVibers committed 12 Oct 2026 · e3e0fb8785 · 3 files, +13 −12

Events retired per-event seq numbers on 10-11 (cursors only). The production proofs (`openvibe-devpath`, `openvibe-toolsjob`) had been failing daily since then because the copy on the host was still the 10-08 one; it now runs main and both pass (11/11 and 6/6).

This drops the last seq reads from the scripts:
- `developer-path.js` and `tools-job-proof.js` printed "seq undefined"; they now name the event ids.
- `e2e.js` set its pull cursor from `pub.seq - 1` (NaN now); it starts the subscriber at the head before publishing, the way the developer path does.

Tests: developer-path, tools-job-proof, structure.
