  • Landlock LSM unprivileged sandboxing
  • Automatic pre-execution rollback checkpoints
  • One-step deterministic remediation rollback
runtimed
/run/syntrop/io.syntrop.Runtime1

ROUTER

Multi-provider LLM reverse proxy and dynamic scoring router. Distributes inference across local runtimed/inferenced instances, LAN runtimed peers, and cloud providers with kernel PSI offloading and zero context contamination.

syntropctl
Unified Operator Client
CLI TOOL

Unified companion CLI tool. Queries daemon health, introspects hardware accelerators, inspects configuration drift diffs, generates shell completions, and formats diagnostic outputs cleanly for humans and JSON consumers.

  • syntropctl explain <unit> - Automated root-cause
  • syntropctl devices - DRM GPU / NPU topologies
  • syntropctl drift - Config chronology diffs

  • Trie-based prefix lookahead over vocabularies
2. Speculative Decoding
inferenced & runtimed
FRONTIER 2

Heterogeneous speculative decoding gang-scheduling draft models onto CPU AMX/AVX-512 engines while target models run on discrete GPU/NPU planes, with O(1) KV-cache truncation.

  • O(1) PagedKvCache rollback without re-computation
  • 2x–3x generation throughput on mixed hardware

  • Autonomous plan generation & tool execution
  • Deterministic circuit-breaker halting flapping
4. Test-Time Compute
routerd & runtimed

5. Streaming Infinite Context & Attention Sinks
runtimed • StreamingLLM
FRONTIER 5

Dynamic state compression with pinned attention sinks (SinkWindowCache, sink_causal_mask) and unrotated RoPE for infinite context generation, paired with bounded StreamJournal to prevent OOM in 24/7 continuous log monitoring.

     Loaded: loaded (/etc/systemd/system/payment-service.service; enabled)
     Active: failed (Result: exit-code) since Wed 2026-09-24 05:14:22 UTC; 18s ago
   Main PID: 84920 (code=exited, status=1/FAILURE)

TRIAGE ANALYSIS (Root-Cause Correlation):
  ├─ Chronology: /etc/systemd/system/payment-service.service.d/override.conf modified 2m ago
  ├─ Config Drift: MemoryMax was reduced from 8G -> 512M
  ├─ Kernel PSI: Memory pressure spiked to 92.4% prior to SIGKILL
  └─ Conclusion: Out-of-memory termination caused by insufficient cgroup limit.

RECOMMENDED REMEDIATION:
  Execute safe drop-in rollback checkpoint:
  $ syntropctl run rollback rb-84920-1a
  Or restore limit:
  # systemctl revert payment-service.service
