 **This is SYSTEMIC, not a one-off.** The same rule fired + attempted auto-isolate on **tps-tina** (The Prairie Schooner) the same day — different GuruRMM script, different client. Per-command-line suppression is whack-a-mole. Note: the isolate-host response only actually cuts a host off where its endpoint policy has isolation enabled (vwp-qbs got isolated; tps-tina fired the same alert but `extensionSuccess=None`, stayed online).
 
+**FLEET-WIDE FIX LIVE (2026-07-07):** Datto EDR suppression rule **`3365e79a`** "GuruRMM origin - Exfil-over-HTTP (fleet-wide FP)" — matches Rule Name = Exfiltration Over HTTP Protocol + Grand Parent = `gururmm-agent.exe`, org/loc empty = ALL clients. Suppresses this one rule for any GuruRMM-launched process fleet-wide (present + future scripts); every other rule still fires on RMM-origin. Created in the CONSOLE (by Howard) after the API create path proved unsafe. The two earlier narrow per-command-line rules (`e4dd55bf`, `7ea2a577`) are now redundant subsets — harmless, left in place.
+
+**API FOOTGUN (do NOT create suppressions via `raw POST` on this tenant):** `POST /SuppressionRules` forces `active:true` and auto-creates an EMPTY match-everything version → a live "suppress all" window (I hit this with `7c36b89f`, deleted within ~2 min). `GET`/`PATCH /SuppressionRules/{id}` 400 ("undefined is not valid JSON"); `DELETE /{id}` works. Create suppressions in the CONSOLE until an atomic API create is verified. Details in `.claude/skills/datto-edr/references/api-reference.md`.
+
 **What's deployed (done):**
 - Narrow suppression rule (Datto EDR, id `e4dd55bf`) for VWP's exact script: matches Process Command Line + Grand Parent = `gururmm-agent.exe`. Does NOT blind other PowerShell. API schema for suppression is now in `.claude/skills/datto-edr/references/api-reference.md`.
 - **EDR isolation watcher**: `.claude/scripts/edr-isolation-watch.sh` + `register-edr-watcher.ps1`, registered as Windows Scheduled Task **"ClaudeTools - EDR Isolation Watcher"** on Howard-Home (runs every 10 min, posts new auto-isolations to #dev-alerts — see [[feedback_fire_dev_alerts_for_client_work]]). Plain script, zero tokens. State file `.edr-watch-state.json` (gitignored) dedupes; seeded with the vwp-qbs + tps-tina event ids so it stays silent for the already-triaged ones. Retire when GuruRMM EDR webhook (Feature 6) lands.

+# Session — GPS-RMM-Progress console popup made silent
+
+## User
+- **User:** Howard Enos (howard)
+- **Machine:** Howard-Home
+- **Role:** tech
+
+## Summary
+Howard reported a command window flashing on the desktop then disappearing. Traced it to
+the `GPS-RMM-Progress` Windows scheduled task and made it run windowless.
+
+## Diagnosis
+- **Task:** `GPS-RMM-Progress` (root `\` folder, author `Howard`)
+- **Old action:** `C:\Program Files\Git\bin\bash.exe -lc "cd /c/claudetools && bash .claude/scripts/gps-rmm-progress-check.sh"`
+- **Trigger:** daily at 08:07 (single fire; no repetition interval)
+- **Root cause of flash:** action launched `bash.exe` (console subsystem) with
+  `LogonType = Interactive` + `Hidden = False`, so a console window drew on the desktop each run.
+- Script is our GPS->GuruRMM enrollment progress check: read-only against RMM `/api/agents`,
+  DMs Howard a daily summary via `discord-dm.sh`. No interactive desktop needed -> safe to hide.
+
+## Fix
+- Added `.claude/scripts/gps-rmm-progress-hidden.vbs` — a wscript wrapper that runs bash with
+  window style `0` (hidden), `False` (no wait). `wscript.exe` is a GUI-subsystem host, so no
+  console is ever allocated.
+- Repointed the task action to:
+  - Execute: `C:\Windows\System32\wscript.exe`
+  - Arguments: `"C:\claudetools\.claude\scripts\gps-rmm-progress-hidden.vbs"`
+- Runtime environment unchanged (same interactive session, vault/SSH/env intact); only the
+  window is suppressed.
+
+## Verification
+- `Start-ScheduledTask GPS-RMM-Progress` -> `LastResult 0x0`, no visible wscript/bash/conhost
+  windows. Flash eliminated.
+- The verification run was a real (non-dry) execution, so it sent Howard the normal daily
+  Discord summary (expected).
+
+## Files changed
+- `.claude/scripts/gps-rmm-progress-hidden.vbs` (new)
+
+## Notes / pending
+- The scheduled task itself is per-machine (not stored in repo) — this fix applies to
+  Howard-Home only. Same change would be needed on any other machine running this task.
+- Script self-reports `COMPLETE` once every tracked GPS client hits its RMM target; at that
+  point the task can be retired: `schtasks /Delete /TN GPS-RMM-Progress /F`.
