Fan-out integration + fixes found by the test/acceptance pass: - FIX ring-buffer: chunks >= capacity skipped bytes now count into the monotonic offset (invariant: stream byte k lives at k % capacity) — window order was corrupted on unaligned big chunks - FIX auth: non-numeric cookie expiry no longer bypasses expiration - FIX protocol: safe-integer validation on ack.bytes / hello.protocol - FIX @fastify/websocket v11: websocket route must be registered in an encapsulated context after plugin load (handler got REST signature) - FIX flow-control deadlock found by e2e acceptance: client only ACKs on data receipt, so pausing with an unACKed residue in (LOW, ACK_EVERY] stalled both sides at 0.9 MB. ACK_EVERY now 64 KiB (<= LOW invariant, tested) + trailing debounced ACK in the web client - Web: Vue 3 + Vite + Pinia + Tailwind 4 + vue-i18n (EN/FR) + xterm 6 (fit + webgl fallback), multiplexed ws-client with reconnect/backoff and resync epochs - Tests: 100 vitest (protocol fuzz, ring edges, auth, pty-manager flow control with mocked pty, REST e2e) ; CI Node 22/24 + pack-smoke - scripts/acceptance-p1.mjs: real daemon + real WS client — boot, login, attach, stdin, 10 MB flood w/ ACK (13.7 MB/1.9s, RSS bounded), brutal disconnect + replay resync, kill broadcast, SIGTERM drain Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
