seon a500c3d40c fix: Alloy block syntax, dpkg lock wait, hitl local bind, ai-reader nodes RBAC, harness image f30af2a
- Alloy 설정 3종: rule 블록을 한 줄 쉼표 나열에서 줄바꿈 속성으로 수정(실측: k8s DaemonSet
  CrashLoopBackOff, db-replica alloy.service "expected TERMINATOR, got ,"). alloy fmt로 3종 파싱 확인.
- vm/postgres-common/alloy.sh: apt에 DPkg::Lock::Timeout=600(db-primary에서 unattended-upgrades 잠금으로 100 종료).
- vm/ai-env/compose.yaml: hitl 8081을 127.0.0.1에만 바인딩(agent는 compose 네트워크로 접근).
- workloads/rbac/ai-reader.yaml: nodes get/list/watch ClusterRole 추가(agent get_k8s(nodes) selfcheck 거부 해소).
- vm/harness/image.tag: f30af2a(POST /proposals/{token}/approve·reject 포함 러너).

vm/harness

Harness VM (10.20.0.11) of the self-healing lab: experiment design 5 (runner, measure DB, blackbox, k6) plus Alloy.

file purpose
apply.sh boot / make vm-sync entry: secrets from Secret Manager to /opt/selfheal/harness/secrets, env file, compose up
compose.yaml runner (8080), measure-db, blackbox (9115), alloy (12345), k6 (profile campaign)
image.tag runner image tag (selfheal-public/harness:<sha> built from selfheal-lab-apps/harness)
scenarios/*.yaml the 12 scenarios of design 7, loaded by the runner at start
config.alloy blackbox + runner scrape -> Mimir remote_write
blackbox.yaml http_2xx (ALB /api/orders, label target=alb) and tcp_connect (target=db-primary)
k6/load.js background load 20 rps (design 5.5)

Runner API (design 5.2):

endpoint use

POST /runs {"campaign","scenario_ids":[...],"baseline_s","cooldown_s","observe_timeout_s","min_observe_s","drift_before"} start a run (one at a time)
GET /runs, GET /runs/{id}, POST /runs/{id}/abort, POST /runs/{id}/finish {"drift_after"} inspect / stop / close
POST /hooks/alert Grafana contact point
POST /proposals AI VM registers a layer-2 proposal; returns the approval token
