# Session Log — 2026-05-15

## Update: 06:21 UTC — Session log housekeeping, submodule sync fix

### Session Summary

After completing the main RMM work (fleet update, dead write-half fix), the session turned to housekeeping: establishing correct session log placement for GuruRMM work and fixing the submodule to stay current on sync.

Session log placement was corrected end-to-end. The convention had been ambiguous — session logs were being committed to the gururmm submodule repo, then the claudetools parent repo updated the submodule pointer, creating unnecessary double commits and coupling session notes to a code repo. The rule was established: GuruRMM session logs belong in claudetools `session-logs/` root, not in the gururmm repo. CLAUDE.md and FILE_PLACEMENT_GUIDE.md were updated with explicit rules. Today's session log (written earlier in the session) was moved from the gururmm repo to the correct location in claudetools.

All historical session logs in the gururmm repo were then audited and migrated. Nine files were found: four were unique to gururmm and copied to claudetools, four had duplicates in claudetools where the gururmm version was more complete (replaced), and one where the claudetools version was longer (kept). All nine were then deleted from gururmm (commit `02d10b7` on gururmm, `3042975` → `02d10b7` on server). The gururmm repo is now session-log-free.

The sync.sh script was updated in two passes to properly maintain the submodule. First pass added a Phase 1a that ran `git submodule update --remote` — this fetched the latest gururmm commits but left the submodule in detached HEAD state. Second pass replaced this with a `set +e`-guarded block that runs `git fetch origin`, `git checkout main`, and `git merge --ff-only origin/main` inside each submodule, ensuring the working tree is on the `main` branch and fast-forwarded. `.gitmodules` was also updated to declare `branch = main` so git knows which remote branch to track with `--remote`.

### Key Decisions

- **Session logs in claudetools, not gururmm**: gururmm is a code repo; mixing session notes into it creates noise in git history and couples operational logs to a repo that developers and tools may clone independently.
- **Replace claudetools with longer gururmm version**: where the same date existed in both repos, line count was used as a proxy for completeness (more lines = session was appended to over time). The one case where claudetools was longer (04-20), claudetools was kept.
- **`set +e` / `set -e` wrapper for submodule ops**: git emits non-fatal status messages ("Your branch is behind") that, under `set -e`, were triggering exit code 128 and killing the script. Temporarily disabling errexit for the submodule section is the standard solution.
- **`git merge --ff-only` rather than `git pull --rebase`**: submodule should never have local commits that need rebasing; if it does, fast-forward failing is the right signal to investigate rather than silently rebase.

### Problems Encountered

- **`set -e` + `git checkout main` = exit 128**: "Your branch is behind 'origin/main'" is stdout output from a successful checkout, but something in the submodule context caused exit code 128. Resolution: wrap the entire submodule block in `set +e` / `set -e`.
- **`git submodule update --remote` leaves detached HEAD**: `--remote` checks out the target commit directly rather than staying on a branch. Resolution: follow with explicit `git checkout main` and `git merge --ff-only` inside the submodule.
- **Binary deployed to wrong path on first try**: copied new server binary to `/usr/local/bin/` but systemd unit points to `/opt/gururmm/`. Resolution: stop service, copy to correct path, start.
- **`cp: Text file busy`**: attempted to copy new binary while service was running. Resolution: stop first, then copy.

## Session Summary

This session was a continuation of a prior context window that had implemented 0.6.19 agent features (extended temperature sensors, wts.rs Windows fixes, watchdog always-on policy changes). The immediate work on entry was completing the 0.6.19 fleet rollout: three agents — IMC1 (fa99e913), GND-SERVER (cd086074), and CS-SERVER (6766e973) — were stuck on 0.6.18 with dead WebSocket write halves. The server's ConnectedAgents in-memory map held stale entries: read side (heartbeats) still worked, but write side (commands) was dead, so update dispatch failed with "Agent is offline" even though DB showed them online.

The first approach was setting those agents offline in the DB to force a reconnect. This failed because the agents were still heartbeating (the server's in-memory read task was alive), so the DB immediately got updated back to online on the next heartbeat. A server restart was needed to clear the in-memory map. After restart, all three agents reconnected with fresh connections within seconds and immediately accepted the 0.6.19 update. All completed successfully within 3 seconds of reconnection.

During log inspection, two server bugs were identified and fixed. First: `TemperatureSensor` struct in `server/src/ws/mod.rs` used field names `temp_celsius` and `critical_celsius`, but the agent's `SensorReading` struct serializes to `value`, `sensor_type`, `unit`, and `critical_value`. Every metrics message from any agent that included temperature readings caused a deserialization error (`missing field 'temp_celsius'`) that was logged but silently dropped the data. Second: the WebSocket receive loop did not monitor the send task. When a WebSocket write failed (killing the send task), the receive loop continued running indefinitely, keeping the agent in ConnectedAgents with a dead write half. Every subsequent command dispatch attempt failed silently. The fix uses `tokio::select!` to watch both incoming messages and the send task — when the send task exits, the receive loop breaks, cleanup removes the agent from ConnectedAgents, and the agent reconnects fresh.

Both fixes were implemented via Python patch script on the server source, compiled with cargo (4m 6s build), and deployed by stopping the service, replacing `/opt/gururmm/gururmm-server`, and restarting. The fixes were committed and pushed to Gitea as commit 56283dd. The patched server ran cleanly with no `temp_celsius` errors and no failed command dispatches in the new process's logs.

At session end: 15 online agents on 0.6.19, AD2 on 0.6.1 (offline since April 20, requires physical/VPN access), and ~30 offline agents on older versions that will auto-update on next reconnect.

---

## Key Decisions

- **Server restart over DB-offline trick**: Setting agents offline in the DB does not disconnect them because the server's in-memory receive loop is still running and updates `last_seen` on every heartbeat, racing with any DB status change. Only a server restart clears the in-memory ConnectedAgents map. Accepted the brief (~10s) outage of all agents.

- **`biased` ordering in select! (send_task first)**: Could have put incoming messages first, but polling send_task first ensures dead write halves are detected on the very next loop iteration rather than waiting for the next incoming message. Incoming messages still get processed every iteration as long as the send task is alive.

- **TemperatureSensor renamed to match agent**: Rather than aliasing with `#[serde(rename)]`, fully renamed the struct fields to match the agent's canonical names (`value`, `sensor_type`, `unit`, `critical_value`). Any previously stored JSON in the `temperatures` column used wrong field names and was silently unreadable, so there's no backward-compat cost to renaming.

- **Edit directly on server vs. local + push**: Local repo is a stale copy of gururmm. Edited the live source on `/home/guru/gururmm/`, built there, deployed, then committed and pushed. Faster than any local→Gitea→pull flow, and the single file edit was low-risk.

- **Deployed first, then pushed to Gitea**: Committed after confirming the fix worked in production. Appropriate for a targeted bugfix with no DB migrations.

---

## Problems Encountered

- **`cp: cannot create regular file '/opt/gururmm/gururmm-server': Text file busy`**: Tried to copy the new binary while the service was running. Resolution: stop service first (`systemctl stop`), then copy, then start. Standard Linux "can't replace a running executable" behavior.

- **Binary deployed to wrong path first**: Copied to `/usr/local/bin/gururmm-server` but systemd unit's `ExecStart` points to `/opt/gururmm/gururmm-server`. The service restarted but ran the old binary. Identified by checking `systemctl show gururmm-server --property=ExecStart`. Resolution: stop/copy to correct path/start.

- **git push rejected (non-fast-forward)**: Remote had commits not in local. Resolution: `git pull --rebase` then `git push`.

- **psql peer auth failed**: `psql -U gururmm gururmm` uses peer auth (Unix socket), requires matching OS user. Used `sudo -u postgres psql -d gururmm` to execute queries as postgres superuser.

- **`temp_celsius` errors in patched server logs**: After deploying the patch (PID 946066), still saw `temp_celsius` errors in `journalctl`. Turned out those error lines had PID 943615 or 945573 (old server instances) — the patched server produced none. Confirmed by filtering with `_PID=946066`.

## Configuration Changes

### Server Source (on `/home/guru/gururmm/`)

**`server/src/ws/mod.rs`** — Two changes:
1. `TemperatureSensor` struct renamed to match agent:
   - `temp_celsius: f32` → `value: f32`
   - `critical_celsius: Option<f32>` → `critical_value: Option<f32>`
   - Added: `sensor_type: String`, `unit: String`
2. `let send_task` → `let mut send_task`
3. Receive loop changed from `while let Some(msg_result) = receiver.next().await` to `loop { tokio::select! { biased; _ = &mut send_task => { warn!(...); break; } msg_result = receiver.next() => { ... } } }`

### Binary Deployed
- `/opt/gururmm/gururmm-server` — replaced with build from 2026-05-15 03:47 UTC

### Commits
- Gururmm repo: `56283dd` — "fix: TemperatureSensor schema mismatch and dead write-half detection"

INFO  gururmm_server::ws: Agent fa99e913... reconnected after update: 0.6.18 -> 0.6.19
```

## Pending / Incomplete Tasks

- **AD2 (0.6.1, offline since 2026-04-20)**: Requires physical or VPN access. Cannot be updated remotely. Low priority but should be investigated when accessible.

- **BB-SERVER enrollment loop**: Repeatedly hitting `duplicate key value violates unique constraint "idx_agents_site_device"` on every WS connect attempt. Not investigated. The agent is already enrolled (row exists) but its auth flow is re-attempting first-time enrollment. Likely needs a code fix in the site-based auth logic to handle "already enrolled, just reconnecting" more gracefully.

- **Offline agents on older versions** (will auto-update on reconnect):
  - 0.6.18: LAPTOP-8P7HDSEI, MSI, Maras-HP-Laptop
  - 0.6.3: ~14 machines (ACCT2-PC, ANN-PC, ASSISTMAN-PC, etc. — Stamback/Safesite fleet)
  - 0.6.2: NurseAssist, PST-SURFACE, StambackLaptopNew
  - 0.6.1: Mikes-MacBook-Air.local (offline)
  - 0.5.1: SL-SERVER x2 (offline, possibly abandoned)

- **`unsupported Unicode escape sequence` on hardware inventory for IMC1**: Logged at `WARN` level after 0.6.19 update. The agent's hardware inventory JSON contains a Unicode escape sequence that PostgreSQL rejects. Likely a field value (serial number, software name, etc.) with a problematic character. Not investigated.

- **Dead write half root cause not fully diagnosed**: We know the pattern (send_task dies, receive loop keeps running), and the fix prevents it from being persistent. But what originally causes the send_task to die (network issue? buffer full? specific message type?) is not determined. The `select!` fix means it self-heals now (agent reconnects), so this is lower priority.

- **Policy wiring plan** (`ticklish-questing-stallman.md`): Full end-to-end policy propagation still pending. Server sends ConfigUpdate on connect (wired), but agent-side handling is not complete. Deferred.

- **Safesite Glendale MSI machine**: Waiting for user to be away to push DisplayLink driver update.

- **LHM bundling in MSI**: LibreHardwareMonitor files not in build pipeline; self-healing download not implemented.

- **Build lock**: No flock on `build-agents.sh` to prevent concurrent invocations.

## Update: 07:50 PT — Network discovery: hostname lookup, subnet auto-detection, fleet update to 0.6.20

## User

## Session Summary

This session picked up from a prior context window that had implemented the network discovery hostname lookup and subnet auto-detection features. All code changes across 8 files had been applied but a compile error was blocking the build: `format!({}/{}, network, prefix)` on line 775 of `agent/src/metrics/mod.rs` was missing quotes around the format string. Fixed with a single `sed` line-number substitution.

Agent and server release builds were launched in parallel. Agent (0.6.19) compiled clean. Server failed with a second missing-quotes error in the new `get_suggested_subnets` handler: `iface.get(ipv4_subnets)` instead of `iface.get("ipv4_subnets")` at line 301 of `server/src/api/discovery.rs`. Fixed and server rebuilt successfully. Dashboard TypeScript build then failed with multiple missing string literals: `.join(, )` instead of `.join(", ")` in two places, bare `manual` instead of `"manual"` in two places (one the earlier Python fix missed), `api.get<string[]>()` with no URL argument, and `setIpRanges()`/`setExclusions()` with no empty-string argument. Each required a targeted fix. The `_getSensorUnit` function in `AgentDetail.tsx` was declared but unused (pre-existing dead code that TS6133 finally flagged); it was deleted.

All three artifacts built clean after the fixes. Server binary was deployed (stop/copy/start pattern), dashboard dist was copied to `/var/www/gururmm/dashboard/`, and all changes were committed to the gururmm repo as `0c60d36`. The `latest` symlink and `gururmm-agent-linux-amd64-latest` were both pointing at 0.6.19, which meant the scanner would not dispatch updates. Version bumped to 0.6.20, rebuilt, and the binary + sha256 placed at `/var/www/gururmm/downloads/gururmm-agent-linux-amd64-0.6.20`. The version bump was committed as `c97b0f3`.

At the 14:47 UTC scan (5-minute interval), the server found 50 binaries (up from 49), immediately identified agents on 0.6.19 as needing an update, dispatched to the first connected agent, and that agent reconnected on 0.6.20 within 11 seconds. Fleet rollout is proceeding automatically on heartbeat.

---

## Key Decisions

- **Single-quoted SSH heredocs do not protect backtick template literals**: Despite using `<< 'ENDSCRIPT'`, bash inside an SSH double-quoted command still executed backtick template literals in the heredoc content as command substitution. Workaround: build the TypeScript template literal string using Python's `chr(96)` to represent the backtick character, passing everything via `python3 -c '...'` with single-quoted outer shell quoting.

- **Version bump to 0.6.20 required to trigger fleet update**: The scanner only dispatches updates when the available version is strictly greater than the agent's reported version. Since the discovery feature changes (PTR lookup, subnet reporting) were built at 0.6.19, a bump to 0.6.20 was needed to push the update to the fleet. Alternative (editing the binary in-place without a version bump) would have left agents unaware of the new capabilities.

- **Correct downloads directory was `/var/www/gururmm/downloads/`, not `/opt/gururmm/updates/`**: The server's `DOWNLOADS_DIR` env var (from `/opt/gururmm/.env`) points to the web-accessible path. The `/opt/gururmm/updates/` directory is not scanned. This was discovered when the scanner continued reporting 49 binaries after placing the file in the wrong location.

- **`latest` symlink updated alongside versioned binary**: The `gururmm-agent-linux-amd64-latest` symlink is used by agent self-updaters that don't know the target version ahead of time. Updated atomically with `ln -sf` to point at 0.6.20.

---

## Problems Encountered

- **`format!({}/{}, network, prefix)` compile error**: Missing double quotes around the format string in the subnet CIDR formatting line. Fixed with `sed -i '775s/...'` line-number substitution.

- **`iface.get(ipv4_subnets)` compile error in server**: Same pattern — missing quotes made Rust look for a variable named `ipv4_subnets`. Fixed with `sed -i` on the specific line.

- **Dashboard TS errors — multiple missing string literals**: Python patch scripts applied earlier in the session used heredocs that silently dropped or corrupted string content (backticks executed as commands, quotes stripped). Result: `.join(, )`, `setIpRanges()`, `setSchedule(manual)`, `api.get<string[]>()` (no URL) in the compiled TypeScript. Fixed with targeted `sed -i` and `python3 -c` with `chr(96)` for backtick characters.

- **`_getSensorUnit` TS6133 error**: Prefixing with `_` does not suppress TS6133 for function declarations (only works for parameters/variables). Resolved by deleting the unused function entirely.

- **Binary placed in wrong updates directory**: Placed initial 0.6.20 binary at `/opt/gururmm/updates/` (wrong) instead of `/var/www/gururmm/downloads/` (correct, from `.env`). Scanner continued to report 49 binaries. Found the correct path by reading `.env` and confirmed by comparing `ls` counts vs the scanner's "49 binaries" log output.

## Pending / Incomplete Tasks

- **Fleet update to 0.6.20**: Rollout underway automatically on heartbeat. Agents update one at a time as they heartbeat. Offline agents will update on next reconnect.
- **AD2 (0.6.1, offline since 2026-04-20)**: Requires physical or VPN access. Unchanged.
- **BB-SERVER enrollment loop**: `duplicate key value violates unique constraint "idx_agents_site_device"` on every WS connect. Agent already enrolled, auth flow re-attempting first-time enrollment. Needs code fix.
- **`unsupported Unicode escape sequence` on hardware inventory for IMC1**: Logged at WARN after 0.6.19 update. Unresolved — likely a problematic character in a serial number or software name field.
- **Policy wiring plan** (`ticklish-questing-stallman.md`): Full end-to-end policy propagation deferred. Server sends ConfigUpdate on connect (wired), agent-side handling not complete.
- **Windows/macOS agents**: Only Linux 0.6.20 built this session. Windows and macOS builds require the `build-agents.sh` script (which handles cross-compilation / signing). Not run this session.
- **LHM bundling in MSI**: LibreHardwareMonitor files not in build pipeline; self-healing download not implemented.
- **Build lock**: No flock on `build-agents.sh` to prevent concurrent invocations.
- **Safesite Glendale MSI machine**: Waiting for user to be away to push DisplayLink driver update.

## Update: 09:13 PT — Zombie connection fix (0.6.21) + automated changelog system

## Session Summary

Investigation began after a screenshot showed a failed network discovery scan at 8:26 AM (19ms, no devices) on the gururmm site. The discovery node (agent 8cd0440f on host `gururmm`) had been unavailable since 14:48:36 UTC — over an hour without reconnecting, despite the process (PID 1026153) still running.

Diagnostic work confirmed the agent had zero TCP connections but was logging metrics every 60 seconds (in two interleaved streams, ~3 seconds apart). The dual metrics stream is normal: the `connect_and_run` metrics task and the `main.rs` metrics loop both log independently. The absence of any reconnect attempts or timeout messages pointed to the agent being stuck inside `connect_and_run` with what appeared to be a live WebSocket but was actually a zombie: Cloudflare held the client-side WebSocket open after the backend server closed it at 14:48:36 (TCP RST), so the agent receive-side was blocking indefinitely with no error.

Root cause in `agent/src/transport/websocket.rs`: the 90-second connection timeout used `tokio::time::sleep(Duration::from_secs(90))` inside the select loop. Because this sleep restarts from zero on every loop iteration — and the heartbeat task fires every 30 seconds, resetting the sleep constantly — the timeout never expired. Fix: track `last_incoming = Instant::now()` initialized before the loop, update it only in the incoming message branch, replace the sleep with `sleep_until(last_incoming + Duration::from_secs(90))`. Timeout now fires if no server message is received for 90 seconds regardless of outgoing heartbeat frequency.

After restarting the service to restore the discovery node immediately, the fix was implemented, agent bumped to 0.6.21, built, and deployed. The scanner picked up the new binary and dispatched auto-update at 16:12:02 UTC. PID changed from 1033371 to 1038912 with "Backup file cleaned up" confirming the full update flow end-to-end.

Second half of the session implemented automated changelog generation. `scripts/generate-changelog.sh` generates two sections per build: a user-facing release notes section (parsed from conventional commits — feat/fix/perf prefixes) and a full developer section (complete git log with commit bodies for the component path since the previous version). Wired into `agent/build-all-platforms.sh` and new `build-server.sh`. Files stored in `changelogs/agent/vX.Y.Z.md` and `changelogs/server/vX.Y.Z.md` in the repo (GrepAI indexes them) and copied to `/var/www/gururmm/changelogs/` for serving. Two server API endpoints added: `GET /api/changelog/:component/latest` and `GET /api/changelog/:component/:version`. All committed and pushed to Gitea.

## Key Decisions

- **`sleep_until` anchored to incoming messages only** — fix must not reset the deadline on outgoing writes. Cloudflare accepts writes from the agent while sending nothing back; any reset on outgoing events would continue masking zombie connections.
- **90-second deadline retained** — matches existing intent. Healthy connections see server messages (ConfigUpdate, AuthAck) on reconnect well within 90 seconds.
- **Service restart before code fix** — restored the discovery node immediately rather than waiting for the full build cycle.
- **Changelog in-repo + served directory** — git repo location ensures GrepAI indexes content for context searches; `/var/www/gururmm/changelogs/` copy serves the API endpoint.
- **No Ollama for changelog generation** — server (172.16.3.30) cannot reach Ollama at 100.92.127.64:11434. Shell-based conventional commit parsing used instead; clean release notes without AI dependency.
- **Version path sanitization in changelog endpoint** — only digits, dots, and leading `v` allowed to prevent path traversal. Component validated against allowlist.

## Problems Encountered

- **Zombie connection not self-detecting**: Agent stuck ~56 minutes without triggering its own 90s timeout. `sleep(90s)` inside select loop resets on every iteration; 30s heartbeats prevented it from ever firing. Fixed with `sleep_until`.
- **Dual metrics stream misread**: Initially suspected as evidence of two concurrent reconnects or task leak. Actually normal — two independent timers started at slightly different times. Not a bug.
- **Changelog directory write permissions**: `generate-changelog.sh` runs as `guru`; `/var/www/gururmm/changelogs/` owned by root. Added `sudo mkdir -p` and `sudo cp` with `|| true` fallback.
- **Heredoc quoting failures**: Multiple SSH heredoc and Python one-liner attempts failed due to quote escaping. Resolved by writing scripts to `/tmp/` locally and using `scp`.

## Configuration Changes

**Modified (gururmm repo):**
- `agent/src/transport/websocket.rs` — `last_incoming` deadline replacing `sleep(90s)`; imports updated
- `agent/Cargo.toml` — version 0.6.20 -> 0.6.21
- `server/src/api/mod.rs` — added `pub mod changelog;` and two changelog routes
- `agent/build-all-platforms.sh` — appended changelog generation call

**Created (gururmm repo):**

- `changelogs/agent/v0.6.21.md`, `changelogs/server/v0.3.1.md`
- `changelogs/LATEST_AGENT.md`, `changelogs/LATEST_SERVER.md`

**Modified (server filesystem):**
- `/opt/gururmm/.env` — added `CHANGELOG_DIR=/var/www/gururmm/changelogs`
- `/usr/local/bin/gururmm-agent` — auto-updated to 0.6.21
- `/opt/gururmm/gururmm-server` — redeployed with changelog endpoint

## Update: 15:20 PT — Pluto SSH recovery, Defender removal, build pipeline repair, perf test

## User
- **User:** Mike Swanson (mike)

- **Role:** admin
- **Session span:** ~18:00 UTC – 22:20 UTC 2026-05-15 (continued from prior context window)

## Session Summary

The session opened with Pluto (172.16.3.36, Windows Server 2019, the Windows build server) offline and unreachable via SSH. Pluto had been unreachable since at least the prior session. SSH key access had been lost — the cause was investigated via Windows event logs pulled through the RMM. The OpenSSH operational log revealed that the last successful connections used key fingerprint `SHA256:FirWvKG7jOqtG2nzX+D0a79/YLFjGAwuWcjP3yz5hCs`, which is root's key on the build server (`/root/.ssh/id_ed25519`), not the guru user's key. This was the root cause of subsequent SSH failures: prior repair attempts added guru's key (`Q+ivqd/...`) instead of root's key. SSH access was restored by adding root's key to `C:\ProgramData\ssh\administrators_authorized_keys` via RMM cmd script. A secondary issue caused the initial repair attempts to fail even with the correct key content: PowerShell's `>` operator writes UTF-16 LE, which Windows OpenSSH silently rejects. The file must be written with explicit ASCII encoding via `[System.IO.File]::WriteAllText(..., [System.Text.Encoding]::ASCII)`. Once both the correct key and correct encoding were in place, SSH worked.

With Pluto accessible, Windows Defender was removed to improve build performance. `Set-MpPreference` and registry policy approaches were blocked by Tamper Protection. DISM failed due to wrong flag syntax for Server 2019. `Uninstall-WindowsFeature` fails over SSH due to a Windows console I/O buffer issue. The only working approach was running `Uninstall-WindowsFeature -Name Windows-Defender -Restart` interactively via ScreenConnect. Pluto rebooted, Defender was fully removed.

With Defender gone, the build pipeline was repaired end-to-end. Three separate issues prevented automatic builds from firing. First: Gitea 1.25.2 blocks webhook delivery to private/internal IP addresses by default — no `[webhook]` section existed in `app.ini`, so all push events were silently dropped. Fix: added `ALLOWED_HOST_LIST = *` to `app.ini` and restarted the Gitea container. Second: the webhook handler (`/opt/gururmm/webhook-handler.py`) used `subprocess.Popen` without ever calling `proc.wait()`, causing every completed build to leave a zombie sudo process. `os.kill(pid, 0)` returns success for zombies, so `is_build_running()` permanently returned True after the first build, silently dropping all subsequent webhooks. Fix: moved build execution to a daemon thread that calls `proc.wait()` and removes the lock file on completion. Third: `administrators_authorized_keys` had guru's key instead of root's key; the build script runs as root via sudo, so only root's key matters. Fix: added root's key via RMM alongside guru's key.

With all three fixes in place, a clean build completed in 42 seconds total (1s Linux, 25s Pluto, rest deploy/sign). The previous baseline with Defender enabled was 367 seconds — an 8.7x speedup. Defender had consumed approximately 325 seconds per build on Pluto alone (scanning cargo output, the sccache directory, and the compiled binaries during linking and signing). A Gitea webhook to the Pluto password (`Paper123!@#`) was also set during the session when Mike reset the Administrator account after the Defender removal complications.

## Key Decisions

- **ASCII encoding for authorized_keys**: PowerShell's `>` and `Out-File` default to UTF-16 LE. Windows OpenSSH requires ASCII or UTF-8 without BOM for authorized_keys files. Silently fails with no error message — looks like a permissions issue. Use `[System.IO.File]::WriteAllText` with `[System.Text.Encoding]::ASCII` exclusively.
- **Root's key, not guru's key**: The build script runs as root via `sudo bash /opt/gururmm/build-agents.sh`. SSH connections to Pluto use `/root/.ssh/id_ed25519`, not `/home/guru/.ssh/id_ed25519`. Both keys should be in `administrators_authorized_keys` — root's for builds, guru's for manual access.
- **Defender removal via ScreenConnect only**: All automated approaches (registry, DISM, scheduled task, `Uninstall-WindowsFeature` over SSH) fail on Server 2019 with Tamper Protection enabled. Interactive console is required. Not worth automating further.
- **Thread-based build dispatch in webhook handler**: Alternative was fixing `is_build_running()` to detect zombies via `/proc/<pid>/status`. Thread approach is cleaner: `proc.wait()` in the thread reaps the child and removes the lock atomically. Lock file is only present while the build is actively running.
- **No manual build runs**: Rule established (and saved to memory) — `build-agents.sh` must only be triggered via the Gitea webhook pipeline. Manual runs execute as `guru` instead of root, breaking log writes, artifact cleanup, and service restart.

## Problems Encountered

- **SSH key wrong user**: Added guru's key to Pluto instead of root's key. Build pipeline uses root. SSH from build server (as guru via manual testing) worked; build pipeline (as root) failed. Fixed by adding root's key via RMM.
- **UTF-16 encoding silently broke SSH auth**: CMD `echo` and PowerShell `>` both produce encodings that Windows OpenSSH rejects. No error in sshd logs — just falls through to password auth. Resolution: `[System.IO.File]::WriteAllText` with explicit ASCII encoding.
- **Gitea silently blocked webhook delivery**: `ALLOWED_HOST_LIST` unset in `app.ini` caused Gitea 1.25.2 to drop all push webhook deliveries to 172.16.3.30 with no log entry, no retry, and a 200 response from the test delivery endpoint. Discovered by checking nginx access logs (zero POST entries from Gitea despite successful pushes).
- **Zombie lock permanently blocking builds**: Every build after the first was silently skipped. `is_build_running()` returned True indefinitely because zombie PIDs respond to `os.kill(pid, 0)`. Discovered by checking lock file PID against `ps` — process showed `<defunct>`. Fixed by reaping child in a thread.
- **Gitea app.ini edit left duplicate `[webhook]` sections**: Echo without `-e` wrote literal `\n` characters. Fixed by pulling the file out of the container with `docker cp`, cleaning with `grep -v`, and pushing back.
- **`Uninstall-WindowsFeature` over SSH returns "Win32 internal error 0x5"**: Not an access denial — the console output buffer isn't available in a non-interactive SSH session. This specific cmdlet requires a real console. Cannot be automated over SSH.

## Configuration Changes

|---|---|---|
| Gitea container | `/data/gitea/conf/app.ini` | Added `[webhook]\nALLOWED_HOST_LIST = *` |

| Pluto | Windows Defender | Fully removed via `Uninstall-WindowsFeature` |
| Memory | `project_pluto_build_server.md` | Added Administrator password, SSH encoding requirement, root key vs guru key distinction |
| Memory | `MEMORY.md` | Added GuruRMM build rule entry |

## Update: 22:45 PT — Platform parity, token efficiency, Linux agent implementation

## User
- **User:** Mike Swanson (mike)
- **Machine:** DESKTOP-0O8A1RL
- **Role:** admin
- **Session span:** ~20:30–22:45 PT

## Session Summary

This portion continued from the earlier webhook/build pipeline work (logged in the 15:20 PT update). The first task was completing the platform parity guideline that had been started before context compaction — a full matrix documenting Windows vs Linux vs macOS agent feature coverage was written into `.claude/CODING_GUIDELINES.md`, along with `#[cfg(...)]` gating guidance and a prioritized gap list.

Mike shared a screenshot of the terminal-bench@2.0 leaderboard showing "vix" ranked #1 at 90.2% accuracy using Claude Opus 4.7. Investigation of the vix GitHub repo revealed it is a third-party AI coding agent built on Anthropic's API with two optimizations: stem agents (preserve prompt cache across explore/plan/execute phases) and a virtual filesystem (code minification for token reduction). Both were evaluated for applicability to ClaudeTools. GrepAI semantic search was identified as the existing equivalent of the virtual filesystem — it eliminates reads entirely rather than just compressing them. The stem agent concept was implemented as a behavioral guideline (single-agent for coupled tasks) rather than new tooling. Four concrete optimizations were applied: CLAUDE.md trimmed ~45 lines, CODING_GUIDELINES.md got a GrepAI-first rule, OLLAMA.md scope expanded to 5 new tier-0 task types, and the agent dispatch section added single-agent guidance for coupled flows.

Mike clarified that "add feature X to the agent" means all three platforms (Windows + Linux + macOS) in the same change, no exceptions. The parity rule was sharpened to match this, and a feedback memory was saved so future sessions enforce it automatically.

The session concluded with a proper Linux agent parity audit via SSH Explore agent on 172.16.3.30. Five genuine gaps were identified: temperature sensors, user idle time, installed software list, running services list, and service checks. A Coding Agent implemented all five. Post-implementation: installed software and running services were already in inventory.rs — the earlier audit had overstated the gaps. Three real gaps were closed (temperature via `/sys/class/thermal`, idle time via xprintidle, service checks via systemctl). Build completed clean in 76 seconds, zero errors.

## Key Decisions

- **GrepAI over minification** — vix minifies code to reduce tokens; GrepAI avoids reading files at all. Semantic search is strictly superior; no minification layer added.
- **Stem agents as discipline** — cache preservation benefit achieved by guideline change (single-agent for coupled tasks), not new infrastructure.
- **Watchdog not ported to Linux** — systemd `Restart=on-failure` provides the equivalent; porting the in-process Rust watchdog would duplicate OS-level functionality.
- **xprintidle for idle time** — subprocess call, zero new Cargo dependencies, gracefully returns None on headless servers where xprintidle is absent.
- **Gaps 3 & 4 already done** — inventory.rs already had dpkg/rpm and systemctl list-units. Coding Agent verified before writing; only wrote what was actually missing.

## Configuration Changes

**Modified (claudetools repo):**
- `.claude/CODING_GUIDELINES.md` — GuruRMM platform parity matrix; GrepAI-first rule; sharpened parity rule wording per Mike's explicit statement
- `.claude/CLAUDE.md` — trimmed ~45 lines: Live State Tracking, Automatic Context Loading, File Placement, Ollama sections compressed; single-agent guidance added
- `.claude/OLLAMA.md` — expanded tier-0 scope: diff summarization, error categorization, agent phase handoff summaries, client email drafts, ticket classification with priority
- `.claude/memory/MEMORY.md` — added GuruRMM agent parity feedback entry

**Created (claudetools repo):**
- `.claude/memory/feedback_gururmm_agent_parity.md` — feedback memory: "add feature X" = all three platforms in same change

**Modified (GuruRMM repo, 172.16.3.30:/home/guru/gururmm):**
- `agent/src/metrics/mod.rs` — Linux temperature via /sys/class/thermal/thermal_zone*; Linux user idle time via xprintidle subprocess
- `agent/src/checks.rs` — Linux service check via systemctl is-active + optional systemctl restart with 3s re-check

## Update: 16:40 PT — M365 alias add (developer@azcomputerguru.com) + Exchange Operator role fix

## User
- **User:** Mike Swanson (mike)
- **Machine:** DESKTOP-0O8A1RL
- **Role:** admin
- **Session span:** ~16:20–16:40 PT, 2026-05-15

## Session Summary

Added `developer@azcomputerguru.com` as an email alias to the ACG Admin distribution group (`admin@azcomputerguru.com`) in the azcomputerguru.com M365 tenant. The target turned out to be a mail-enabled distribution group (not a user mailbox), which required Exchange Online cmdlets rather than Graph API to modify.

Initial attempts via Graph PATCH on the group object failed with 403 from both user-manager and tenant-admin tiers, since distribution list proxyAddresses are Exchange-managed and cannot be written via Graph. Pivoted to the exchange-op tier and the EXO admin REST API (InvokeCommand). The exchange-op token acquired successfully but InvokeCommand also returned 403, revealing the Exchange Operator service principal had zero directory roles assigned in the ACG tenant — Exchange Administrator was missing.

Assigned Exchange Administrator to the Exchange Operator SP (OID: `83c225f1-b38d-4063-9fdd-642b6b09ae8b`) using the tenant-admin tier. After an 8-second propagation wait, retried InvokeCommand with `Set-DistributionGroup`. The hash table add syntax (`{"Add": [...]}`) was rejected by the REST API with a type conversion error; resolved by passing the full flat address list as a replacement array. Change confirmed live after a 20-second Exchange replication delay.

Subsequently searched mike@azcomputerguru.com's mailbox (via investigator tier / Graph Mail.Read) for Apple emails. Found a verification email from `appleid@id.apple.com` sent to `admin@azcomputerguru.com` at 23:31 UTC — arrived minutes after the alias was added, confirming the use case. Also surfaced an Apple Developer Program enrollment thread from 2026-05-11 (enrollment ID HH5UA87LAH, currently stalled on identity verification).

Also answered a user question about the Claude Code "fan out agents" prompt — the feature that spawns parallel agents in isolated git worktrees for large parallel tasks, triggered via `/batch`.

## Key Decisions

- **Used Exchange Online InvokeCommand instead of Graph PATCH** — distribution lists (groupTypes: []) are Exchange-managed; Graph PATCH on proxyAddresses is not supported for this recipient type regardless of permission tier.
- **Passed full address list rather than hash table add syntax** — EXO REST API InvokeCommand does not support PowerShell hash table parameters (`@{Add=...}`); the only working approach was providing the complete replacement array including all existing entries.
- **Assigned Exchange Administrator role to Exchange Operator SP for ACG tenant** — the MSP apps had never been onboarded against the ACG own tenant; this was a gap. The role was assigned permanently (not PIM-managed) using tenant-admin tier.
- **Used investigator tier for mailbox search** — user-manager and exchange-op both lack Graph Mail.Read; investigator has it as part of its read-only audit scope.

## Problems Encountered

- **Graph PATCH 403 on group proxyAddresses** — both user-manager and tenant-admin returned 403; root cause was that DL proxyAddresses require Exchange Online write, not Graph directory write. Resolved by switching to InvokeCommand.
- **Exchange Operator InvokeCommand 403** — Exchange Operator SP had no directory roles in the ACG tenant (Exchange Administrator was missing). Resolved by assigning the role via tenant-admin Graph token. Side note: this gap means all previous exchange-op attempts against azcomputerguru.com would have failed the same way.
- **Set-DistributionGroup hash table parameter rejected** — `{"Add": [...]}` format caused a Newtonsoft.Json type conversion error in the EXO REST layer. Resolved by fetching current addresses via Get-DistributionGroup and passing the full array as a replacement.
- **20-second replication delay** — alias did not appear in immediate verify call; confirmed live on second check after waiting.

## Update: 01:30 PT — VM detection, Docker install path, Jupiter deployment

## User
- **User:** Mike Swanson (mike)
- **Machine:** DESKTOP-0O8A1RL
- **Role:** admin
- **Session span:** ~23:00 PT (May 15) to 01:30 PT (May 16)

## Session Summary

This portion began after the Linux parity implementation. Mike asked whether VMs pass through temperature data to the guest OS. The answer is no: KVM/QEMU virtualizes the CPU and does not expose host thermal sensors to guests. This led to implementing VM detection and temperature suppression in the dashboard, plus a host-to-guest chaining feature to show which VMs belong to which hypervisor hosts.

A Coding Agent added five new fields to HardwareInventory across all three platforms: is_virtual_machine, hypervisor_type, vm_uuid, is_hypervisor, hosted_vm_uuids. Linux detection reads /proc/cpuinfo hypervisor flag and /sys/class/dmi/id/sys_vendor. Windows uses WMI Win32_ComputerSystem. DB migration 032 added columns non-destructively. The server API was extended to resolve host-guest relationships at query time from inventory UUIDs and return them on the agent detail endpoint. The dashboard was updated: temperature widgets show explicit "N/A - Virtual Machine" instead of blank, and agent detail pages show Host and Guest VM links. All three builds passed clean: agent 1m22s, server 4m4s, dashboard 11.4s Vite.

Mike then asked whether the Linux agent would run on Jupiter (Unraid). The answer: the binary runs, but the systemd installer fails and service-related features do not work. The correct approach for Unraid is a Docker container. A Coding Agent implemented the full Docker install path: container-mode config resolution (GURURMM_CONFIG env var, then /config/ volume, then /etc/gururmm/ fallback), Unraid and container detection in inventory, Docker socket-based container enumeration as the service list on Unraid, and an installer path that prints docker run instructions instead of attempting systemd. A Dockerfile was written using debian:bookworm-slim plus the docker CLI (125 MB compressed). build-agents.sh was updated to build and push the image to the Gitea registry at 172.16.3.20:3000 after each Linux build.

Jupiter (172.16.3.20, Unraid 7.2.5) was then deployed manually. Direct pull from 172.16.3.20:3000 requires insecure-registry config; restarting Docker on Jupiter would briefly kill 30+ production containers. Discovery: Docker 29.3 trusts localhost registries without any config change. Since Gitea runs on Jupiter itself, pulling from localhost:3000 resolved to the same image. Jupiter was enrolled to the GuruRMM Debug site, config written to /mnt/user/appdata/gururmm/config.toml, container started with host networking plus /sys, /proc, and docker socket mounts. Agent came online immediately. Also discovered: Unraid persistent Docker daemon config is /boot/config/docker.cfg (USB boot drive), not /etc/docker/daemon.json which does not exist on Unraid.

## Key Decisions

- **Explicit N/A text for VM temps** - showed "N/A - Virtual Machine" rather than blank or zero so the absence of data is clearly intentional.
- **Host-guest resolution at query time** - matched VMs to hypervisor hosts by UUID at API call time rather than storing a FK. Avoids migration complexity for a low-frequency lookup.
- **Docker container for Unraid** - native binary install requires custom rc.d scripts and non-persistent /etc/; Docker is Unraid native app model.
- **localhost:3000 instead of insecure-registry config** - restarting Docker on Jupiter would disrupt Plex, Gitea, Overseerr, and ~27 other containers. Docker 29.3 trusts localhost registries without config. Pulled from localhost:3000 since Gitea runs on Jupiter itself.
- **GuruRMM Debug site for Jupiter** - Jupiter is ACG internal infrastructure; GuruRMM Debug (d6b8233a) is the appropriate ACG-internal site.
- **Unraid daemon config location** - /boot/config/docker.cfg is persistent (USB boot drive); /etc/docker/daemon.json does not exist on Unraid.

## Problems Encountered

- **docker save | ssh pipe timed out** - 120s Bash tool timeout hit before 120MB image transferred over the SSH pipe. Resolved by using localhost:3000 pull instead, which is a local pull on Jupiter itself.
- **Build server cannot SCP to Jupiter** - root key from build server (172.16.3.30) is not in Jupiter authorized_keys. Resolved by the localhost pull approach.
- **Gaps 3 and 4 already implemented** - earlier audit overstated the Linux gaps; inventory.rs already had dpkg/rpm and systemctl list-units. Coding Agent verified before writing anything.

## Update: 21:11 PT — Jupiter hypervisor wiring, Pluto VM detection, watchdog fix, dashboard terminal layout

### User
- **User:** Mike Swanson (mike)
- **Machine:** DESKTOP-0O8A1RL
- **Role:** admin
- **Session span:** ~03:00-21:15 UTC 2026-05-16 (continued from previous context window)

### Session Summary

Picked up from a context-compacted prior window where three bugs had been identified: Jupiter's Docker container lacked /dev/kvm, Pluto's Windows agent was not detecting itself as a VM, and both is_container/is_unraid columns were missing from the database. The prior window had already applied DB migration 033 and pushed a KVM detection fix (30016da), but those were not verifiable until this session resumed.

The Jupiter container was recreated with /dev/kvm mounted, confirming is_hypervisor: true in the inventory API. However, hosted_vm_uuids remained empty because virsh was not installed in the Docker image (only ca-certificates and docker.io were present). Added libvirt-clients to the Dockerfile, pushed to Gitea, and the build pipeline produced a new Docker image. Recreating the container with the new image still yielded empty hosted_vm_uuids — the libvirt socket was not mounted. The libvirt socket path on Unraid (/var/run/libvirt/libvirt-sock) was discovered and mounted. virsh then enumerated 7 hosted VMs and hosted_vm_uuids populated correctly. The host-guest UUID matching on the server side linked the GuruRMM server agent (gururmm) to Jupiter as its hypervisor host.

For Pluto, the WMI detection fix had been compiled into v0.6.21 but Pluto was already running v0.6.21 from a prior build, so the auto-updater skipped re-delivery. The agent version was bumped to 0.6.22 and the pipeline rebuilt. Pluto received the update command on reconnect but its GuruRMM service went offline and did not recover automatically for ~25 minutes. Investigation via paramiko SSH (sshpass unavailable, VPN was connected providing direct access to 172.16.3.36) found GuruRMMAgent stopped. The agent log showed a two-stage failure: the watchdog received RestartMainService IPC but service.stop() via the windows-service SCM API returned access denied, then the watchdog entered 14 minutes of suppression mode instead of resuming monitoring immediately. Service was manually started and came back online on v0.6.22 with is_virtual_machine: true, hypervisor_type: KVM, and hypervisor_host linked back to Jupiter.

Three watchdog bugs were patched: (1) RestartMainService falls back to sc.exe stop when the SCM API call fails; (2) suppress_until is set to Instant::now() on restart failure so monitoring resumes immediately; (3) PerformUpdate warning demoted to debug since the updater handles its own binary swap without watchdog involvement. The v0.6.22 changelog was generated (the generate-changelog.sh script existed but was not wired into build-agents.sh) and the pipeline hook was added. Finally, a layout bug in the dashboard Terminal tab was fixed: NativeSelect was applying the caller's className to the inner select while the outer wrapper div had hardcoded w-full, causing the div to claim the entire flex row and squeezing the command input to zero width. The fix moved className to the outer div; twMerge ensures caller width classes override the default w-full. The terminal output panel was also enlarged from h-80 to h-[28rem].

### Key Decisions

- **libvirt socket path vs. libvirtd TCP**: Mounted /var/run/libvirt/libvirt-sock (Unix socket) rather than configuring libvirtd to listen on TCP. Unix socket is safer and avoids reconfiguring Unraid libvirtd.
- **Version bump to 0.6.22 instead of content-addressing**: The auto-updater compares version strings; it cannot detect a same-version binary with different content. Bumping was the only reliable way to force re-delivery.
- **paramiko over sshpass**: sshpass not installed. paramiko handles password SSH from Python without an interactive TTY.
- **NativeSelect className to outer div**: All callers pass only width classNames. Moving className to the outer div is safe; twMerge resolves the conflict with the default w-full. The inner select always uses w-full to fill its container.
- **Changelog wired into build-agents.sh**: Called just before the "Build complete" log line, keeping it atomic with the build.
- **Live terminal deferred**: xterm.js/PTY bridge is a future feature. Current command-dispatch model is sufficient.

### Problems Encountered

- **virsh not in Docker image**: hosted_vm_uuids empty after /dev/kvm mount. Fix: added libvirt-clients to Dockerfile, rebuilt image.
- **Wrong libvirt socket path**: virsh failed with "No such file or directory: /var/run/libvirt/libvirt-sock". Checked /var/run/libvirt/ on Jupiter and mounted the correct path.
- **Pluto auto-update stuck for 25 minutes**: watchdog received RestartMainService but SCM service.stop() returned access denied, then suppression mode held 14 minutes. Unblocked by manual Start-Service via paramiko. Root cause fixed in watchdog.
- **SSH password auth non-interactive**: ssh prompts but cannot receive password in non-interactive shell; sshpass not installed. Resolved with paramiko.
- **NativeSelect outer div w-full**: Wrapper div claimed full flex width regardless of w-32 passed by callers. ChevronDown appeared at absolute right-2 of the full-width div (far right of page). Fixed by moving className to outer div.

### Pending / Incomplete Tasks

- **Pluto vault entry**: Paper123!@# needs infrastructure/pluto-build-server.sops.yaml
- **Pluto SSH key**: Add DESKTOP-0O8A1RL pubkey to Pluto authorized_keys
- **macOS agent**: No Docker/install path. build-agents.sh has TODO-MACOS
- **Live terminal**: xterm.js + PTY bridge deferred to future feature
- **Policy wiring plan**: ticklish-questing-stallman.md plan exists, deferred
- **BB-SERVER enrollment loop**: Pre-existing duplicate key constraint, not addressed
- **PowerShell command_type bug**: Agent prepends -OutputEncoding UTF8 -Command incorrectly on Windows PS 5.1
- **Dashboard VM badges**: Data now correct in API; verify dashboard VM/Hypervisor badge renders on both Jupiter and Pluto agent detail pages
