From 15e117673d2303bf476d4f78699e47913ce1aec0 Mon Sep 17 00:00:00 2001 From: Christophe Besson Date: Thu, 1 Oct 2026 10:34:26 +0200 Subject: fix(node): one member holds a share of the node, sized past real use 128 peer sessions on the node, at most 64 per account (the hub names the account with each offer; the node's own account is not counted). One account plays at most half the stream slots, rounded up, and runs two subtitle extractions at once. Frames after the handshake are 8 MiB (was 64), decoded with per-container bounds, and a frame refused for either ends the session instead of jamming its buffer (F-16). Sized for the heaviest real member: twenty groups on one node, three devices and a tab, up to 52 sessions. Measured: ~0.15 MiB and one fd per idle session.
