+## Design Decisions (Verified 2026-07-12, Reaffirmed 2026-07-18)
 
 1. **Fan control**: ❌ NO auto fan control. Load-side cooling only (reduce concurrency, redirect).
 2. **Model restart**: ✅ Only if >50% failure rate over 60s + 30s grace period. Not on single stuck request.
 3. **Strix direct access**: ✅ Open firewall .15:8080 → .24 for direct health probe + restart.
-4. **VRAM thresholds**: Tiered — 100MB/h (RTX 3090), 50MB/h (RTX 5070), 200MB/h (Strix).
-5. **CB auto-reset**: ✅ With rate limit — 1 test inference + 60s cooldown + max 1/hour per GPU.
-6. **Benchmark baseline**: Rolling 30-day average, recalculated weekly. Original baseline kept in Grafana.
+4. **VRAM thresholds**: Tiered — **300MB/h** (RTX 3090), **300MB/h** (RTX 5070), 200MB/h (Strix). Previous values (100/50) were too sensitive; raised 2026-07-18 based on operational data.
+5. **CB auto-reset**: ✅ Router deprecated — circuit breakers go through LiteLLM health check + container restart if needed. No per-GPU auto-reset.
+6. **Benchmark baseline**: Rolling 30-day average, recalculated weekly. Current baselines live in gpu-monitor.
 7. **Predictive alerts**: Two-tier — warn at >70°C+rising (>2°C/min), critical at >80°C+rising.
-8. **Prometheus**: Primary source. Fall back to nvidia-smi/rocm-smi direct probes if exporter down.
+8. **Prometheus**: ❌ Not deployed. Use direct sidecar probes (:8080/health) and gpu-monitor API. Prometheus integration deferred until exporters are running on GPU hosts.

+## Lessons Learned (2026-07-12, Updated 2026-07-18)
 
 ### L1: API Key Standardization Is Critical
 - All GPU llama-servers MUST use the same api-key as the LiteLLM config.
 - RTX 5070 had `--api-key sk-loc...5678` while LiteLLM sent `not-needed`.
-  This caused cascading 401 → fallback → timeout → 401 loops, burning all retries.
-- **Rule**: Any new GPU or model restart MUST verify api-key matches LiteLLM config.
+  This caused cascading 401 → fallback → timeout → 401 loops.
+- **Rule**: Any new GPU or model restart MUST verify api-key matches LiteLLM config (`not-needed` for direct routing).
 
 ### L2: Fallback Chain Cascading Failures
 - When one model returns 401 (auth) and another is slow (timeout), the fallback
-  chain creates an infinite loop: gemma 401 → qwen timeout → gemma 401 → ...
+  chain creates an infinite loop.
 - **Rule**: If a model returns 401 (auth error), do NOT fall back to it again.
   Mark it as permanently failed for this request.
 
 ### L3: Verify Running State, Not Docs
-- RTX 3090 was documented at 128K context. Actually running at 256K.
-- Parallel count wrong (docs said 2, actual is 1 on RTX 3090).
+- RTX 3090 was documented at 128K context. Running at 128K (verified 2026-07-18).
+- Parallel count: 1 on both RTX 3090 and RTX 5070 (matches docs for current models).
 - **Rule**: Before making decisions, check `/proc/PID/cmdline` on GPU hosts.
 
 ### L4: Infisical Is Not Always Available
-- Tanko's Infisical service token was 404 — gateway ran without API key for hours.
-- **Rule**: Always keep a local `.env` fallback for `LITELLM_API_KEY`.
-- Contract hermes-config-template Rule 3 updated.
+- Keep a local `.env` fallback for `LITELLM_API_KEY`.
+- **Rule**: Always verify credential source is reachable before relying on it.
 
-### L5: Zulip Event Queue Can Silently Die
-- Mumuni's queue accumulated 41 errors/reconnects then stopped polling.
-  Gateway was running but ignoring all messages.
-- **Rule**: litellm-health-check now monitors gateway responsiveness via Zulip API.
+### L5: GPU Monitor Response Size Can Cause Self-Heal Crash
+- gpu-self-heal crashed with KeyboardInterrupt during json.loads() of 20MB response.
+- Root cause: router poll returns accumulated data → cache balloons.
+- **Rule**: Self-heal must enforce a read timeout AND max response size on every poll.
+  If monitor response > 1MB, log a warning and skip the cycle rather than crashing.
+
+### L6: Stable Aliases Replace Model Names
+- gpu-fleet introduced stable aliases (strix-moe, gpu-dense, gpu-light) on 2026-07-15.
+- Self-heal must use aliases for reporting and alerting, not model-specific names.
+- **Rule**: All alert messages and KG nodes use the stable alias as the GPU identifier.
