 - [GuruRMM technical reference](reference_gururmm.md) — Server (172.16.3.30) layout + downloads dir `/var/www/gururmm/downloads` + `.channel` sidecar rollout control (stable/beta) + privileged server access via the server's OWN root RMM agent (hostname `gururmm`, no SSH needed; plink fallback) + API + `context=user_session` (WTS impersonation) + build-pipeline vendoring at `deploy/build-pipeline/` + Linux agent systemd sandbox trap.
 - [GuruRMM command timeout_seconds](reference_gururmm_command_timeout_seconds.md) — agent command dispatch honors `timeout_seconds`, NOT `timeout`; long jobs die ~300s / go zombie (`running`, empty stdout) otherwise. Cost Birth Biologic a full day.
 - [SharePoint Graph large-file upload](reference_sharepoint_graph_large_file_upload.md) — <4MB simple PUT, >=4MB MUST use chunked upload session (Content-Range); `\\?\` long paths; idempotent size-check; verify counts via /root/delta; single stream ~40Mbps (SPO throttle).
+- [Exchange REST uses exchange-op tier](reference_exchange_online_exchangeop_tier.md) — ALL Exchange adminapi (Get-Mailbox/InboxRule/MailboxPermission, Set-*) goes through `exchange-op`, NEVER `investigator-exo` (401s: Security Investigator app lacks `Exchange.ManageAsApp`). 401=wrong app→exchange-op; 403=missing Exchange Admin role. Recurred 6+ times.
 - [RMM-spawn headless Claude](reference_rmm_spawn_headless_claude.md) — run `claude -p` on any RMM-managed Windows box with Claude Code (reaches coord-isolated sites like AD2); use `context:user_session`, UNSET the stale machine `ANTHROPIC_API_KEY` (shadows OAuth → "Invalid API key"), detach + poll a DONE marker. Validated on AD2 2026-07-01.
 - [RMM agent update model](rmm-agent-update-model.md) — Agent updates are server-PUSH on heartbeat (no self-poll); available versions = filesystem scan needing a `.sha256`; promote flips `.channel` sidecars beta→stable globally. Two stranders: beta-first freezes stable until an explicit promote; agents older than ~0.6.50 re-enroll with a NEW device_id/agent row when updated.
 - [GuruRMM physical server storage](gururmm-physical-server-storage.md) — New box 172.16.1.231 (temp IP→will be .30), Ubuntu 26.04, ssh key `gururmm-physical`/alias `gururmm-new`. SSD (915G root) = HOT (PG default tablespace + WAL + builds); HDD ext4 at `/data` = COLD (`gururmm_cold` PG tablespace for aged `agent_logs` partitions + downloads + backups + archive). The #3 retention answer.

 - [Background tasks — no shell `&`](feedback_background_task_no_ampersand.md) — with run_in_background:true, run the command in the foreground of the shell; adding `&`/`disown` forks + exits 0 instantly, orphaning a blocking wait so it never delivers (hit twice building ask-forum)
 - [ask-forum — human-in-the-loop via #ct-forum](../skills/ask-forum/SKILL.md) — ask a teammate a question in the private ct-forum Discord forum, get their human answer back in-session; forum-only, any human can answer, run the --wait as a proper background task
