- stop counting ACK and Pong frames toward the per-connection frame window;
draining a large queue used to trip the 429 limit, disconnect the client
and, after eight rounds, drop the remaining envelopes
- deliver to online recipients with try_send: a recipient that stops reading
its socket no longer pins the sender's task and memory
- throttle call wake-ups per recipient (1 per 10 s, 6 per 10 min) and
ordinary wake-ups (1 per 5 s); collapse ids for APNs and FCM
- POST /v1/register accepts X-Sepot-Identity-Proof and lets a new device take
over an existing identity (restore from the recovery phrase)
- POST /v1/keys uploads one-time prekeys and rotates signed/Kyber prekeys;
PrekeysLow is sent after AUTH when fewer than 20 remain
- GET /v1/keys hands out at most 30 one-time prekeys per address per hour
- reqwest errors are logged without the URL; UnifiedPush POSTs pin the
addresses the SSRF guard resolved; NAT64/6to4 embedded addresses are checked
- absolute AUTH deadline, at most 3 AUTH attempts, length limits on push
endpoints and VoIP tokens
- TURN credentials live 12 h and are reissued per connection every 10 min
- global attachment storage cap (SEPOT_ATTACHMENTS_TOTAL_BYTES), nosniff and
attachment disposition on downloads
- SEPOT_MAX_CONNS_PER_IP, /v1/ready backed by the database, graceful shutdown,
RLIMIT_NOFILE raised to the hard limit, server-info reports source and revision
- Dockerfile: rust 1.99, GIT_SHA build arg for the image label and
SEPOT_REVISION; Tor image on alpine 3.24
