Session Summary

Started by diagnosing a stray C:\Program Files\Git\bin\bash.exe console window on the Howard-Home desktop. Traced it to the GPS-RMM-AutoEnroll scheduled task (runs gps-rmm-autoenroll.sh every 30 min), which was visible because its principal used LogonType: Interactive. Confirmed the running instance was mid-sleep 150 (normal, after pushing 3 installers), not hung. Changed the principal to S4U (runs hidden in Session 0), verified via a test run, then — per Howard's follow-up — disabled the task entirely (manual enrollment going forward) and killed the leftover Session-0 bash processes.

Built the structure for a fleet-wide client Wi-Fi inventory so techs can connect onsite without asking. Security-driven split: passwords go encrypted in the SOPS vault (clients/<slug>/wifi.sops.yaml, credentials.<key>_ssid/_password), and a human-readable index (no passwords) lives at wiki/reference/client-wifi.md (registered under a new "Reference" section in wiki/index.md, exempt from /wiki-compile). Per Howard's choices via AskUserQuestion: structure-only for now (the /wifi importer is deferred), dedicated wiki doc. Added a reference_client_wifi_inventory memory documenting the convention.

Deployed the BUG-024 fix (Linux agent glibc-floor crash-loop). Verified GURU-5070's fix/linux-musl-glibc-floor branch (rustls on non-Windows, x86_64-unknown-linux-musl static, objdump build gate), merged it to gururmm main (a73dcad). Discovered the webhook SKIPPED the Linux rebuild — the change-detector excluded agent/Cargo.toml, and the fix was Cargo.toml-only. Forced build-linux.sh as root on .30; the objdump gate PASSED and published a verified glibc-free static 0.6.79 to beta (Linux un-quarantined). Then fixed the detector gap itself (BUG-025, fe5468e) in both build-linux.sh and build-windows.sh, validated on real commits.

Attempted to recover the last still-dead Linux agent, Scileppi's SL-SERVER (Synology RS2212+). Howard stood up OpenVPN into Scileppi's network; SL-SERVER (192.168.242.5) became reachable but SSH resets at the banner (sshd restricts to the LAN subnet; my VPN IP 10.137.42.119 is off-subnet), and the vault DSM/user creds all fail DSM login (400, likely stale since the 2025-12-29 migration). The Mac mini jump-host path proved unreliable (T-Mobile public IP, and ScreenConnect returns no command output). Escalated to Mike via Discord DM.

Closed the session by reviewing the three bugs touched: marked BUG-024 and BUG-025 FIXED in FEATURE_ROADMAP.md, then dug into why BUG-024's crash-loop never self-recovered. Root-caused it: the unix rollback watchdog is spawned inside the agent's systemd cgroup (setsid changes session, not cgroup), so KillMode=control-group (default; unit sets none) SIGKILLs it during the restart it's meant to guard — and it's the only rollback path on unix. Filed as BUG-026 (OPEN/HIGH) and, per Howard, flagged it for Mike to fix (coord todo + Discord DM) rather than implementing it.

Key Decisions

• Disabled (not deleted) GPS-RMM-AutoEnroll so it can be re-run manually; used S4U before deciding to disable, proving the hidden-run path works if re-enabled.
• Wi-Fi passwords go in the vault only; the wiki holds a passwordless index. Placed the index under wiki/reference/ specifically because /wiki-compile only touches clients/projects/systems slugs, so it won't be clobbered.
• Forced the Linux build manually on .30 rather than waiting on the webhook, because the change-detector gap meant the webhook would never rebuild a Cargo.toml-only change. Rebuilt as 0.6.79 (same version GURU-5070 validated), relying on the objdump gate as the safety net.
• Fixed BUG-025 by counting meaningful Cargo.toml lines (excluding only the [package] version = line) instead of excluding the manifest wholesale — preserves the version-bump false-positive guard while catching real dep/feature changes.
• Did NOT implement the BUG-026 watchdog fix; flagged for Mike per Howard. The fix (systemd-run --scope) touches the self-update path and needs testing on a real systemd host.
• Left 0.6.79 on beta to soak; stable promotion is a deliberate separate step.

Problems Encountered

• Webhook skipped the BUG-024 Linux build. build-linux.sh/build-windows.sh excluded agent/Cargo.(toml|lock); the fix was Cargo.toml-only → AGENT_CHANGED=0 → skipped. Resolved by forcing the build (cleared /opt/gururmm/last-built-commit-linux so the skip guard's -n "$LAST_SHA" was false), then fixed the detector (BUG-025).
• Repeated sync races + a MEMORY.md rebase conflict. GURU-5070 was auto-syncing frequently; three push races and one line-ending conflict in .claude/memory/MEMORY.md (Mike's normalized version vs my one-line add). Resolved by git checkout --ours + re-adding the single line. Also caught two empty .ocu.err/.ocu.json scratch files that git add -A swept in; removed from tracking and added .ocu.* to .gitignore.
• Scileppi SL-SERVER unreachable for remediation. SSH banner-reset (source-subnet restriction), DSM API creds fail (400), Mac mini on a foreign network + no SC command-output retrieval. Not resolvable without Mike changing NAS/VPN access or providing current creds; escalated.
• /tmp write blocked by hook. Wrote a JSON dump to /tmp/mini.json; block-tmp-path.sh correctly rejected it (Windows path mismatch rule). Switched to the scratchpad.

Configuration Changes

• wiki/reference/client-wifi.md — created (Wi-Fi inventory doc, no passwords).
• wiki/index.md — added "Reference" section + row.
• .claude/memory/reference_client_wifi_inventory.md — created; .claude/memory/MEMORY.md — index line added (survived a rebase conflict).
• .gitignore (claudetools) — added .ocu.*.
• Scheduled task GPS-RMM-AutoEnroll (Howard-Home) — principal set to S4U, then task Disabled.
• guru-rmm deploy/build-pipeline/build-linux.sh + build-windows.sh — BUG-025 detector fix.
• guru-rmm docs/FEATURE_ROADMAP.md — BUG-024 → FIXED, BUG-025 filed FIXED, BUG-026 filed OPEN.
• Server .30: /opt/gururmm/last-built-commit-linux cleared then repopulated; /var/www/gururmm/downloads/gururmm-agent-linux-amd64-0.6.79 (+ .channel beta + .sha256) published; /tmp/musl-build worktree removed; fix/linux-musl-glibc-floor remote branch deleted.

Credentials & Secrets

• SL-SERVER (Scileppi Synology RS2212+) vault entry clients/scileppi-law/rs2212.sops.yaml: credentials.username: sysadmin, credentials.password: Gptf*77ttb123!@#-sl-server (the \! in the vault is shell-escape notation), users chris/andrew/sylvia/rose = Scileppi2025!. NOTE: all of these FAIL DSM login (400) — likely stale since the 2025-12-29 migration. No SSH private key is stored in the entry despite the "SSH key auth configured" note. Flag for update once working access is regained.
• gururmm server SSH: infrastructure/gururmm-server-physical.sops.yaml, credentials.username: guru, credentials.ssh-private-key (ed25519), sysadmin password credentials.password. Reaches guru@172.16.3.30 (hostname gururmm). Key extracted to scratchpad during the session and deleted after use.

Infrastructure & Servers

• GuruRMM build/deploy server: 172.16.3.30 (hostname gururmm, Ubuntu 26.04, guru user, SSH key auth). Downloads dir /var/www/gururmm/downloads, quarantine /var/www/gururmm/quarantine, linux build log /var/log/gururmm-build-linux.log, last-built marker /opt/gururmm/last-built-commit-linux.
• Scileppi: SL-SERVER Synology RS2212+ at 192.168.242.5 (LAN 192.168.242.0/24); DSM API on :5000/:5001 reachable but auth fails; SSH :22 TCP-connects but resets at banner (subnet-restricted). Vault host field says 172.16.1.59 (unreachable — stale/mgmt IP). OpenVPN client IP this session: 10.137.42.119.
• Mac mini "Mac-mini-2" (Sylvia, Apple M4) — ScreenConnect session b9fb0065-a00e-08fe-bdbc-5d9d93c17245, Company "The Law Offices of Chris Scileppi"; online but public IP 172.59.206.208 (T-Mobile, not Cox), so possibly off the office LAN.

Commands & Outputs

• Set-ScheduledTask -TaskName 'GPS-RMM-AutoEnroll' -Principal (New-ScheduledTaskPrincipal -UserId 'Howard' -LogonType S4U -RunLevel Limited) then Disable-ScheduledTask.
• Force build: ssh guru@172.16.3.30 "sudo -S bash -c 'rm -f /opt/gururmm/last-built-commit-linux && /home/guru/gururmm/deploy/build-pipeline/build-linux.sh'" → BUG-024 gate PASSED — static musl binary, no glibc floor → Linux build complete: v0.6.79.
• Verify static: objdump -T <bin> | grep -c GLIBC_ = 0; readelf -l <bin> | grep -c INTERP = 0; ldd = "statically linked"; file = "static-pie linked".
• Detector validation: BUG-024 change 2471946 → 25 meaningful Cargo.toml lines (build); version bump c81eeb5 → 0 (skip).
• Scileppi SSH: kex_exchange_identification: read: Connection reset (system ssh + paramiko), from first attempt. DSM login: all accounts {"error":{"code":400}}.

Pending / Incomplete Tasks

• Scileppi SL-SERVER recovery (BUG-024 straggler) — BLOCKED on access. With Mike (Discord DM 1523821940047876146): needs VPN subnet 10.137.42.0/24 whitelisted for SSH on the NAS (or VPN NAT to LAN), OR current DSM creds, OR the authorized SSH key location. Vault creds clients/scileppi-law/rs2212 are stale and need updating once in.
• BUG-026 — flagged for Mike (coord todo f7382334, Discord DM 1523834569760178259). Fix: spawn watchdog via systemd-run --scope --collect + bounded retry loop + verify agent stays up.
• 0.6.79 stable promotion — left on beta to soak; promote deliberately later (/opt/gururmm/promote-* or the pipeline).
• /wifi importer — deferred; build once a few real networks are captured. Schema in wiki/reference/client-wifi.md.

Update: 2026-07-07 08:47 PT — bug roadmap close-out + Discord read capability

Continuation of the same session (spanned past midnight into 2026-07-07).

Bug tracking (guru-rmm docs/FEATURE_ROADMAP.md):

• BUG-024 → FIXED and BUG-025 (build change-detector excluded agent/Cargo.toml) filed FIXED (fe5468e) — commit c248214.
• Dug into why BUG-024's crash-loop never self-recovered → root-caused and filed BUG-026 (OPEN/HIGH, commit 66152da): the unix rollback watchdog is spawned via setsid inside the gururmm-agent.service cgroup; the unit sets no KillMode so the default control-group SIGKILLs the watchdog during the very restart it guards (setsid changes session, not cgroup). It is the only rollback path on unix (restart_service does std::process::exit(0) before the inline rollback_binary arm is reachable). Fix = spawn via systemd-run --scope --collect + bounded retry + verify. Per Howard, flagged for Mike to fix, not implemented: coord todo f7382334 + Discord DM 1523834569760178259.

Discord reply visibility gap (resolved):

• Discovered discord-dm.sh was send-only, so replies from mike/winter/rob were invisible (coord/repo sync never carries Discord replies). Confirmed the bot token CAN read DM history via GET /channels/<id>/messages (Message Content intent only gates gateway events, not REST fetch on channels the bot participates in).
• Added discord-dm.sh read <user|#channel> [limit] (reuses the same recipient/token/DM-open logic; prints oldest-first, >>> = their reply). Updated the SKILL.md + trigger description; added feedback memory feedback_discord_read_replies. Synced (skill deployed to global).
• Findings from reading: Mike has NOT replied to Scileppi (2026-07-06 22:44) or BUG-026 (23:34) — his last reply was 2026-07-05 (MSP360/Datto backups thread). Winter has a stale unanswered ask from 2026-06-24: "mark tickets resolved that have a status of customer reply and also have billing" (Syncro cleanup — not yet actioned, flagged to Howard).

Decision: automated reply-forwarding (a scheduled watcher polling read, or a bot-side relay) was scoped but NOT built — Howard opted to check replies manually via discord-dm.sh read <user> when needed.

Still waiting on Mike: (1) Scileppi SL-SERVER access to finish BUG-024's last agent, (2) BUG-026 fix. Check with discord-dm.sh read mike.
