| 2026-09-01 | VPS SSH (local-vps-reference:22) is rate-limited/firewalled: >3 failed connect attempts within a period blocks the IP for a while. Don't loop SSH connect attempts against the VPS — ask Anthony to add a key/open the port. Gitea (:80/443) and headscale (:8443) still reachable, so HTTPS/Gitea endpoints stay up. | Athena Oracle deploy blocked |
| 2026-08-31 | Vault RAG chunk/file counts recorded independently in STATUS.md, HOME.md, and 01_user/current-context.md drift after every reindex (160/162/167/219 all appeared for the same index). Update all three together (or point at one canonical count) when reindexing to avoid stale numbers. | AgentOS merge reindex |
| 2026-08-30 | LFM2.5-2.6B is both agentic AND a pure reasoning model. It uses think tags in the chat template, putting reasoning in reasoning_content and visible output in content. Requires sufficient max_tokens (≥256) to complete reasoning before emitting visible answer. |
LFM2.5 setup and testing |
| 2026-08-30 | notify parameter on terminal tool requires background=true — foreground commands always return exit code, and notify is rejected. Use background mode for daemons/services. |
LFM2.5 launch debugging |
| 2026-08-30 | Llama.cpp --n-gpu-layers 999 is required for full CUDA offload on Windows. Without it, the model runs on CPU only. |
LFM2.5 setup |
| 2026-08-30 | LFM2.5-2.6B (Q4_K, ~2.1GB) + FreeToken gpt-oss-20b (~12.8GB) cannot coexist on RTX 3060 12GB. Only one can run at a time. | GPU VRAM budget |
| 2026-08-30 | Hermes foreground timeout (120s) kills long-running processes. Use background=true for daemons, then verify with separate curl. |
Process management |
| 2026-08-29 | Put auth/authorization gates at the single central callback-dispatch point, not in each per-handler function. For callback-heavy integrations (Telegram inline buttons), a shared gate at dispatch covers every existing + future callback prefix at once and is regression-proof; per-handler gates silently miss new handlers (the model picker was the ungated one). | Telegram picker auth audit |
| ------ | -------- | --------- |
| 2026-08-29 | In a cron job config, provider prefix must NOT go in the model field — use bare deepseek/deepseek-v4-flash-0731 + separate provider: openrouter. Sending openrouter/deepseek/... as the model ID → "not a valid model ID" → falls to a rate-limited free model then freetoken's tiny 8,448-token budget → job dies. |
Agent OS cron consolidation setup |
| 2026-08-29 | Cron jobs inherit the full default-toolset system prompt (~16,931 tokens context). Huge context overflows tiny fallback models with small KV budgets. Give cron jobs a minimal toolset (e.g. read, files) like check-agent-discussion (~2,648 tokens). |
Agent OS cron consolidation setup |
| 2026-08-29 | Files in a session that came back as base64 text on disk (memory_policy.md, lessons.md) were real corruption — the decoder (read_file) hid it. Always verify a file's on-disk content is plain markdown, not base64. |
Vault Agent OS setup — base64 corruption bug |
| 2026-08-29 | /model <name> in Hermes is session-scoped; use --global or hermes config set model.default to persist. Config/status showing a different model than the live session = split-brain from session-level switches. |
Model switching permanence |
| 2026-08-29 | `hermes fallback add | removeare interactive pickers that reject bare model strings; set the wholefallback_providerslist viahermes config set` instead. |
