+## Incident Log: 2026-07-09 — amdpve docker bloat
 
-## Storage Summary
+### Discovery
+Scheduled fleet disk scan via `pct-run` across all 15 CTs + 3 GPU bare-metal hosts.
+amdpve (.15) flagged at 78% (AMBER threshold: 75%).
 
-| System | Used | Free | Health |
-|--------|------|------|--------|
-| **Abiba** (CT 100) | 12G / 59G (21%) | 45G | ✅ Green |
-| **kagentz** (CT 105) | 16G / 59G (27%) | 41G | ✅ Resolved (was 87%) |
-| **/var/lib/docker** (abiba) | 2.8G | — | Fine |
-| **/root/go** (abiba) | 773M | — | Fine |
+### Diagnosis
+- amdpve (.15, Strix Halo host): 70G used / 94G total (78%)
+- Docker images: 1 image, 0 containers running, 15.47GB (100% reclaimable)
+- Image: `llama-strix-hip:latest` — abandoned ROCm/HIP Docker build from 7 days ago
+- Root cause: Strix Halo migrated from Docker-based HIP path to bare-metal Vulkan
+  (`/root/llama.cpp/build-vk/`) but the old Docker image was never cleaned up
+- Not a running service — zero containers, zero active volumes
 
-## New Contract: `disk-gc-threat-response.prose.md`
+### Resolution
+```
+docker system prune -a --force
+→ Reclaimed 11.56GB
+→ Post: 55G / 94G (62%), 35G free
+→ 1 image removed (llama-strix-hip:latest, 15.5GB)
+→ 8 build cache layers removed
+→ amdpve now GREEN
+```
 
-Created at `/root/prose-contracts/disk-gc-threat-response.prose.md`. Here's what it does:
+### Root Cause
+Technology migration (Docker HIP → bare-metal Vulkan) left orphaned build
+artifacts. Docker on amdpve serves no running purpose — it's only used for
+one-off GPU builds. No automated post-migration cleanup was in place.
 
-### Three-in-One
+### Preventive Measures
+- amdpve added to Docker GC scan list
+- Post-migration cleanup step added: after any GPU backend migration, prune
+  the old backend's Docker images within 24 hours
+- Contract now scans GPU bare-metal hosts alongside CTs
+- Access via `pct-run` script for all CTs (no hardcoded IPs)
 
-1. **Infra Update** — Fleet-wide disk scan every 6 hours across all 19 CTs, with per-host GC strategy (Docker hosts vs standard LXC). Today's incident is logged as the baseline.
+## Access Matrix (documented 2026-07-09)
 
-2. **Garbage Collection** — Tiered response: Phase 1 (`docker system prune -f`) for amber, Phase 2 (`-a --force`) for red, Phase 3 (`--volumes` + `builder prune --all`) for critical. Non-Docker CTs get `apt clean`, log rotation, journalctl vacuum.

-3. **Threat Resolution** — Five severity levels (Green → Amber → Red → Critical → Full), with escalating alerts via Zulip DM, channel, and relay to you for critical breaches. kagentz is flagged HIGH risk due to Agent Zero dev patterns.
-
-### The incident root cause
-Agent Zero was repeatedly rebuilding `kagentz-bridge`, generating 5 dangling images and 15 build cache layers. No automated GC existed. Recovery: **35.67GB freed** in one `docker system prune -a --force`.
