Session Summary

Three distinct work streams ran this session: Jupiter Unraid container templating, a GURU-KALI ghost-agent investigation that turned into a GuruRMM bug-tracking cleanup, and an EZ Fast Auto Glass email-deliverability investigation.

Jupiter Docker → Unraid templating. Inspected all 21 containers on Jupiter (172.16.3.20). 14 were created via raw docker run/docker-compose and lack the net.unraid.docker.* labels that drive the Unraid UI (WebUI button, icon, update-check, Edit form). Because those labels are immutable, the fix requires recreating each container. Executed target #1 (lowest risk): wrote an Unraid template for gururmm-agent, recreated it with net.unraid.docker.managed=dockerman and the faithful config; verified it re-authenticated and resumed reporting. Then added a device-id persistence mapping (/var/lib/gururmm → appdata) after noticing the agent's identity was ephemeral. Produced a full plan doc and held the higher-risk recreates (seafile, gitea, npm — compose stacks/public proxy) for a maintenance window.

GURU-KALI ghost agents. A ghost check after the Jupiter work surfaced ~11 duplicate GuruRMM agent rows for hostname GURU-KALI. Traced it to a daily device_id churn: the agent could not persist /var/lib/gururmm/.device-id. My initial diagnosis ("host root filesystem is read-only") was wrong — commands dispatched through the RMM agent execute inside the agent's ProtectSystem=strict systemd sandbox, so they showed the agent's namespace view, not the host. Sent the diagnosis to GURU-KALI's own Claude session via the coord API as a self-heal experiment; it correctly identified the real cause (the systemd unit's ReadWritePaths omitted /var/lib/gururmm), applied a drop-in override, and reported back. Purged the ghosts (keeper 9bca5090, stable device-id ec975630), discovering the DELETE /api/agents/:id endpoint is buggy (resets the connection / commits asynchronously). Filed three bugs and reconciled the bug-tracking system: GuruRMM bugs live as BUG-NNN sections in docs/FEATURE_ROADMAP.md (not Gitea issues), so BUG-018 was added there and the duplicate coord todos were closed.

EZ Fast Auto Glass Amazon email. Jon Shailer reported Amazon emails possibly blocked/filtered. ezfastautoglass.com email is hosted on the IX cPanel server (172.16.3.10 / 72.194.62.5). Exim logs over ~3 weeks showed every Amazon SES message accepted, scored NOT spam, delivered to the local mailbox AND forwarded to jshailer1@gmail.com (Gmail returns 250 OK). Nothing is blocked server-side. The likely cause is Gmail filing the forwarded mail into Spam/Promotions, aggravated by SRS being disabled (srs=0) so forwards fail SPF at Gmail. Drafted client instructions (Gmail filter + POP3 pull) and opened Syncro tracking ticket #32359.

Key Decisions

• Templated gururmm-agent via CLI docker run with the net.unraid.docker.managed=dockerman label rather than the Unraid web UI — replicates exactly what Unraid's docker manager does, and works over SSH. Verified the label + faithful config post-recreate.
• Mapped /var/lib/gururmm to appdata for gururmm-agent so the agent's device-id survives recreates; copied the existing device-id out first so identity stayed stable (no new enrollment).
• Held seafile/gitea/npm recreates for a maintenance window — compose stacks should be adopted into the Compose Manager plugin (already installed), and npm/gitea are high-blast-radius (public proxy / repos + build pipeline). Discourse (app) left alone — self-managed by its own ./launcher.
• Used the coord API to hand the GURU-KALI diagnosis to its own Claude session as a self-heal test instead of remediating it remotely. It succeeded and corrected my misdiagnosis.
• Finished the ghost purge via the Database Agent (direct SQL) rather than the flaky DELETE /api/agents/:id API. The API deletes turned out to commit asynchronously, so the ghosts were already gone by the time the DB Agent checked.
• Kept GuruRMM bug tracking in FEATURE_ROADMAP.md (no Gitea issues) per Mike, and added BUG-018 there for consistency; closed the interim coord todos as duplicates.
• For ezfastautoglass, concluded the server is not at fault and pointed remediation at Gmail (filter) + an optional POP3-pull / SRS change, rather than touching the mail server reactively.
• Did not include the mailbox password in the client email draft — instructed that ACG provides it securely.

Problems Encountered

• Misdiagnosed GURU-KALI as "host fs read-only." RMM-agent-dispatched shell commands run inside the agent's ProtectSystem=strict mount namespace (/ is ro there), so findmnt/touch reflected the sandbox, not the host. Resolved by GURU-KALI's own session (the real cause was the unit's ReadWritePaths missing /var/lib/gururmm). Saved as memory reference_rmm_agent_runs_in_systemd_sandbox.md.
• DELETE /api/agents/:id returned HTTP 000 for all-but-one delete per burst. Consistent across 3 runs. Determined the deletes actually commit asynchronously (ghosts cleared ~5 min later with no further calls); likely a missing index on child-table agent_id FK columns making the ON DELETE CASCADE slow enough to reset the connection. Filed as BUG-018.
• post-bot-alert.sh returned Discord 400 (invalid JSON) on a message containing a Unicode em-dash/arrow — the helper does not JSON-escape non-ASCII. Resolved by resending ASCII-only. Helper bug noted.
• Plink first-connect to IX server failed in batch mode (host key not cached). Resolved by pinning the presented fingerprint with -hostkey.
• Parent claudetools push rejected (non-fast-forward) during the BUG-018 commit — resolved by the Gitea Agent with git pull --rebase then push (no force).

Configuration Changes

Created:

• wiki/systems/jupiter-docker-templating.md — Jupiter container inventory + recreate plan + execution log (gururmm-agent done, device-id fix, ghost-check notes).
• .claude/memory/reference_rmm_agent_runs_in_systemd_sandbox.md (+ MEMORY.md index pointer).
• clients/ezfastautoglass/jon-amazon-email-instructions.txt — client email draft (still untracked at save time; will be committed by sync).
• On Jupiter: /boot/config/plugins/dockerMan/templates-user/my-gururmm-agent.xml.
• On GURU-KALI: /etc/systemd/system/gururmm-agent.service.d/override.conf (ReadWritePaths=/var/lib/gururmm) — applied by GURU-KALI's session.

Modified:

• projects/msp-tools/guru-rmm/docs/FEATURE_ROADMAP.md — added BUG-018 (gururmm commit c0c0119).
• Jupiter: gururmm-agent container recreated twice (managed label; then + /var/lib/gururmm mapping). Backup /root/gururmm-agent.inspect.bak.json.
• GuruRMM DB: GURU-KALI ghost agent rows deleted (11 → 1 keeper 9bca5090).

Closed (coord todos, status=done): 7eb7e60a, 5ada8ff4, 04497b97 (all dupes of BUG-016/017/018).
