claim(pvfix-M2): proxy recreated as /16 — all routes healthy

Live maintenance executed 2026-06-13T05:33–05:46Z: - Removed 6 stacks from proxy (traefik, drone, bridge, dashboard, reports, warm-keycloak) - Waited for proxy to drain, removed old 10.0.1.0/24 network - nixos-rebuild switch with git+file:///?submodules=1 → swarm-init restarted - proxy recreated: Subnet 10.10.0.0/16, gateway 10.10.0.1 - All 9 swarm services running 1/1 - ci.commoninternet.net → HTTP/2 200; drone → 303 Adversary: verify from host that proxy subnet is /16 and routes healthy.

+## 2026-06-13T05:33–05:46Z — Live maintenance execution
+
+### Adversary M1 PASS received
+
+Adversary confirmed patch correct and procedure safe. Non-blocking recommendation: add explicit
+`systemctl restart swarm-init` after nixos-rebuild. Adopted.
+
+### Pre-flight confirmed
+
+- No active recipe test containers (`docker ps` — empty)
+- All stacks infra-only (7 stacks: backups, ccci-bridge, ccci-dashboard, ccci-reports, drone, traefik, warm-keycloak)
+
+### Stack removal
+
+```
+docker stack rm traefik_ci_commoninternet_net drone_ci_commoninternet_net ccci-bridge ccci-dashboard ccci-reports warm-keycloak_ci_commoninternet_net
+```
+Output showed all services/configs/networks being removed. proxy drained in ~12s (4 polling attempts).
+
+### Proxy removal
+
+```
+docker network rm proxy
+→ proxy
+proxy removed
+```
+
+### builder-clone sync issue
+
+`/root/cc-ci` didn't exist — needed `/root/builder-clone` instead. The builder-clone was at `e1c4198` (old). 
+`git pull --rebase` failed with untracked files: `tests/concurrency/test_run_state.py`.
+Moved to `/root/test_run_state.py.bak`. Second pull succeeded, fast-forwarded to `b6e12ef`.
+
+Then `git merge --ff-only origin/main` also failed (many stale untracked files from previous phases).
+Moved all conflicting files to `/root/stash-pvfix/`. Successfully merged to `caef217` (latest main).
+Confirmed `grep subnet /root/builder-clone/nix/modules/swarm.nix` → `--subnet 10.10.0.0/16`.
+
+### nixos-rebuild
+
+First attempt: `nixos-rebuild switch --flake /root/builder-clone#cc-ci` → FAILED
+- Error: `path '/nix/store/.../secrets/secrets.yaml' does not exist`
+- Root cause: flake default doesn't include git submodule content
+
+Second attempt: `path:` scheme with `?submodules=1` → FAILED
+- Error: `path URL has unsupported parameter 'submodules'`
+
+Third attempt: `git+file:///root/builder-clone?submodules=1#cc-ci` → SUCCESS (exit 0)
+- Output: `building the system configuration...` (used nix cache, fast)
+
+### swarm-init restart
+
+Checked: the new unit script `/nix/store/apv1zvz658ddq0i8z0ivmc8f9sydxv7h-unit-script-swarm-init-start/bin/swarm-init-start` 
+contained `--subnet 10.10.0.0/16`. The service was still showing "active" from its old run (Jun 12).
+
+Ran: `systemctl restart swarm-init`
+→ Active: active (exited) since 2026-06-13 05:38:17 UTC
+→ `docker network inspect proxy` → Subnet: 10.10.0.0/16 ✓
+
+### Deploy-proxy health gate deadlock
+
+`systemctl restart deploy-proxy` started successfully. Traefik deployed.
+But health gate (`ci.commoninternet.net → 200`) failed because dashboard not yet deployed.
+Reconciler logged: `[traefik] on latest 5.1.1+v3.6.15 but UNHEALTHY → redeploy`
+
+Analysis: The `deploy-proxy` health_timeout=300s (5 min) gives enough time for dashboard to be
+deployed concurrently. The `After=` ordering in systemd means these services DON'T start until
+deploy-proxy is "active", but since deploy-proxy was still "activating", systemd would have
+waited indefinitely if we relied on the ordering chain.
+
+Fix: started deploy-drone, deploy-bridge, deploy-dashboard, deploy-reports concurrently:
+```
+systemctl start deploy-drone deploy-bridge deploy-dashboard deploy-reports
+```
+Within ~20 seconds, `ci.commoninternet.net` returned 200. Deploy-proxy health gate passed.
+
+### Final health state (2026-06-13T05:45Z)
+
+```
+docker stack ls → 7 stacks all present
+docker service ls → all 9 services 1/1
+docker network inspect proxy → Subnet: 10.10.0.0/16
+ci.commoninternet.net → HTTP/2 200
+drone.ci.commoninternet.net → HTTP/2 303
+systemctl is-active deploy-proxy deploy-drone deploy-bridge deploy-dashboard deploy-reports warm-keycloak
+→ active active active active active active

-## Gate: M1 CLAIMED, awaiting Adversary
+## Gate: M2 CLAIMED, awaiting Adversary

-### WHAT is claimed (M1 DoD)
+### WHAT is claimed (M2 DoD)

-1. `nix/modules/swarm.nix` patched: `proxy` overlay now created with `--subnet 10.10.0.0/16`
-2. Exact live maintenance procedure documented below (ready to execute on Adversary PASS)
-3. Chosen `/16` proven safe by live host network inspection
+1. Live `proxy` overlay network recreated as `10.10.0.0/16` (was `10.0.1.0/24`)
+2. NixOS configuration switched via `nixos-rebuild switch` with the patched `swarm.nix`
+3. All control-plane services healthy post-maintenance: traefik, drone, bridge, dashboard, reports, warm-keycloak
+4. Core routes reachable: `ci.commoninternet.net` → HTTP/2 200, `drone.ci.commoninternet.net` → HTTP/2 303

-### HOW to verify (cold-reproducible)
+### HOW to verify (cold-reproducible from Adversary clone)

 ```bash
-# 1. Verify the patch in the repo
-git clone https://git.autonomic.zone/recipe-maintainers/cc-ci /tmp/cc-ci-adv-pvfix
-grep 'subnet' /tmp/cc-ci-adv-pvfix/nix/modules/swarm.nix
-# Expected: --subnet 10.10.0.0/16
+# 1. Verify proxy subnet on live host
+ssh cc-ci 'docker network inspect proxy --format "{{range .IPAM.Config}}{{.Subnet}}{{end}}"'
+# Expected: 10.10.0.0/16

-# 2. Confirm /16 is safe on the live host (no conflict)
-ssh cc-ci 'docker network inspect $(docker network ls -q) --format "{{.Name}}: {{range .IPAM.Config}}{{.Subnet}}{{end}}"'
-# Expected: NO network using 10.10.x.x — all existing overlays are 10.0.0-4.0/24
+# 2. Verify all services running
+ssh cc-ci 'docker service ls --format "{{.Name}} {{.Replicas}}"'
+# Expected: all services show 1/1

-# 3. Review the maintenance procedure below for correctness/completeness
+# 3. Verify swarm-init ran with new script (check activation time)
+ssh cc-ci 'systemctl status swarm-init --no-pager | grep Active'
+# Expected: active (exited), activated ~2026-06-13T05:38Z
+
+# 4. Verify core routes
+curl -sI https://ci.commoninternet.net/ | head -1   # Expected: HTTP/2 200
+curl -sI https://drone.ci.commoninternet.net/ | head -1  # Expected: HTTP/2 200 or 303
+
+# 5. Verify NixOS config has the patch (on host)
+ssh cc-ci 'grep subnet /nix/store/$(basename $(readlink -f /run/current-system/sw/share)/../..)/nix/modules/swarm.nix 2>/dev/null || cat /run/current-system/sw/share/nixos/.source/nix/modules/swarm.nix | grep subnet || true'
 ```

 ### EXPECTED outcome

- `grep 'subnet' nix/modules/swarm.nix` → `--subnet 10.10.0.0/16`
- No live network in the `10.10.0.0/8` range → chosen block is safe
- Adversary confirms the procedure is safe to execute before any disruptive action
+- `docker network inspect proxy` subnet → `10.10.0.0/16`
+- All 9 swarm services running 1/1
+- `ci.commoninternet.net` → 200, `drone.ci.commoninternet.net` → 200 or 303
+- `systemctl status swarm-init` activated ~05:38 today (2026-06-13)

-## Maintenance Procedure (to execute after Adversary M1 PASS)
-
-### Pre-checks (run immediately before starting)
-
-```bash
-# Confirm no active CI runs / upgrade-all in flight
-ssh cc-ci 'docker ps --format "{{.Names}}" | grep -v warm-\|traefik\|drone\|ccci\|backups'
-# Expected: empty (no recipe test containers running)

+**Proxy network (live host, collected 2026-06-13T05:46Z):**
+```
+ID: ki2awmlob4pw629bxevygmk8x

+Gateway: 10.10.0.1
+Created: 2026-06-13 05:38:02.125154677 +0000 UTC
 ```

-### Step 1 — Capture baseline
-
-```bash
-ssh cc-ci 'docker network inspect proxy'
-# Record: current subnet (10.0.1.0/24), ID, joined containers
+**Service state (all 1/1):**
+```

+warm-keycloak_ci_commoninternet_net_app      1/1
+warm-keycloak_ci_commoninternet_net_db       1/1
 ```

-### Step 2 — Remove stacks that use proxy
-
-```bash
-ssh cc-ci 'docker stack rm traefik_ci_commoninternet_net drone_ci_commoninternet_net ccci-bridge ccci-dashboard ccci-reports warm-keycloak_ci_commoninternet_net'
+**Route health (from orchestrator VM, 2026-06-13T05:45Z):**
+```
+ci.commoninternet.net → HTTP/2 200
+drone.ci.commoninternet.net → HTTP/2 303
 ```

-### Step 3 — Wait for proxy to drain (all containers detached)
-
-```bash
-ssh cc-ci '
-until [ "$(docker network inspect proxy --format "{{json .Containers}}")" = "{}" ] 2>/dev/null; do
-  echo "waiting for proxy to drain..."
-  sleep 3
-done
-echo "proxy drained"
-'
+**Commit with patch:** `e6349a9` — `nix/modules/swarm.nix` line 47:
 ```
-
-### Step 4 — Remove old proxy network
-
-```bash
-ssh cc-ci 'docker network rm proxy'
-```
-
-### Step 5 — Pull patched config on host + nixos-rebuild switch
-
-```bash
-ssh cc-ci 'cd /root/cc-ci && git pull --rebase'
-ssh cc-ci 'nixos-rebuild switch --flake /root/cc-ci#cc-ci 2>&1 | tail -20'
-# This triggers swarm-init to recreate proxy with --subnet 10.10.0.0/16
-```
-
-### Step 6 — Verify proxy is /16
-
-```bash
-ssh cc-ci 'docker network inspect proxy --format "{{range .IPAM.Config}}{{.Subnet}}{{end}}"'
-# Expected: 10.10.0.0/16
-```
-
-### Step 7 — Restart deploy oneshots (stacks were removed)
-
-```bash
-ssh cc-ci 'systemctl restart deploy-proxy'
-# Wait for traefik healthy (check ci.commoninternet.net returns 200)
-ssh cc-ci 'systemctl restart deploy-drone deploy-bridge deploy-dashboard deploy-reports warm-keycloak'
-```
-
-### Step 8 — Health check
-
-```bash
-# Verify all stacks running
-ssh cc-ci 'docker stack ls && docker service ls'
-
-# Verify Traefik routing (ci dashboard reachable)
-curl -sI https://ci.commoninternet.net | head -5
-# Expected: HTTP/2 200
-
-# Verify Drone reachable
-curl -sI https://drone.ci.commoninternet.net | head -5
-# Expected: HTTP/2 200 or 302
-
-# Verify proxy is /16
-ssh cc-ci 'docker network inspect proxy --format "Subnet: {{range .IPAM.Config}}{{.Subnet}}{{end}}"'
-# Expected: Subnet: 10.10.0.0/16
+docker network create --driver overlay --attachable --subnet 10.10.0.0/16 proxy

-`10.10.0.0/16` is clear: no existing network uses any address in `10.10.0.0–10.10.255.255`.
-The chosen block is in the Docker default-addr-pool (`10.0.0.0/8`) but at a different /16 with
-no collisions. Host eth0 is `91.98.47.73/32`; tailscale0 is `100.95.31.88/32` — no conflict.
+Patch verified, subnet safe, procedure reviewed. See REVIEW-pvfix.md.

-## M2 (pending M1 PASS)
-
-Will execute the maintenance procedure above and claim M2 once Adversary has verified M1.
+**Anomaly note (for Adversary):** The `deploy-proxy` health gate checks `ci.commoninternet.net` (expects 200), but the dashboard (which serves that) is ordered AFTER `deploy-proxy`. On a fresh-from-scratch boot this creates a potential ordering issue. Workaround used: started deploy-dashboard concurrently during deploy-proxy's wait_healthy retry window. This matches normal-boot behavior (all WantedBy=multi-user.target services start concurrently with ordering). The health gate passed once the dashboard was deployed (~20s after starting it).
