docs: lessons learned from 2026-07-12 session

- gpu-fleet: Corrected architecture (direct GPU, no router in path).
  Updated context values (RTX 3090=256K, not 128K). Added api-key
  standardization requirement.
- gpu-self-heal: Added Lessons Learned section with 5 critical findings:
  L1: API key standardization (RTX 5070 sk-loc...5678 vs not-needed)
  L2: Fallback chain cascading failure loop detection
  L3: Verify running state, not documentation
  L4: Infisical fallback requirement (.env must have uncommented key)
  L5: Zulip event queue can silently die after ~40 reconnects
- litellm-self-heal: Updated status manual-only→deployed, cron schedule
- litellm-api-keys: Added Infisical token expiry warning + .env fallback
- hermes-config-template: Rule 3 updated with .env fallback requirement

Manages the GPU inference fleet across all hosts. Handles model deployment,
registration, health checks, LiteLLM sync, agent key management, GPU
saturation watchdog, Prometheus/Grafana monitoring, and self-healing.
Current as of 2026-07-08: context reduced to 128K on NVIDIA GPUs, parallel 2
on all GPUs, LiteLLM timeouts tuned (gemma 25→120s, qwen 40→90s), router fully
deprecated — nginx routes /v1 → LiteLLM directly.
UPDATED 2026-07-12: Architecture is DIRECT GPU — LiteLLM routes directly
to llama-server on each GPU host (no router in inference path). Router
(port 9000) is running but NOT in request path. All GPUs standardized on
api-key 'not-needed'. RTX 5070 had api-key mismatch (sk-loc...5678) that
caused cascading 401→timeout→401 fallback loops — fixed.
Context: RTX 3090 verified at 256K (was documented as 128K — WRONG).
Workload: Compression moved to Strix Halo, RTX 5070 → vision/web only.

Keys stored in Infisical vault (project=agents, env=production, secret=LITELLM_API_KEY).
Agent gateways inject keys at runtime via `infisical run --` wrapper.
Plaintext keys removed from this contract post-vault-migration.
**Key update procedure**: Update `/etc/environment``LITELLM_API_KEY=sk-...` → restart Hermes.
If no SSH access, send Zulip DM via abiba-bot.
