feat(examples): CMR beta lab on 7.26beta1, with rechecked MikroTik findings (#183) - #184
Conversation
…ndings (#183) Four socket-linked CHRs: a CMR controller, a transit router, a client reachable only over OSPF, and a client that finds its controller by discovery. The lab pairs them, then exercises labels, fleet scripts, topology, alerts and HTTP webhooks. `--probe` adds the pairing matrix, export versus binary backup, and a real outage of the remote client. Each support-report finding was reproduced again on a fresh lab. Three are confirmed: export omits the controller settings, client `pairing-requirement=confirm` is rejected, and the first bridge on a device does not fire `interface-change=added`. Client disable/enable clearing pairing is added as a question. "Routed client does not reconnect after restart" is withdrawn: while OSPF had no route, the connect left via the user-mode default route, and its SYN kept the 10.0.2.15 source. The lab now resets tcp/54321 outbound on ether1, and the full `--probe` run passes. Marked as a beta lab, work in progress. Adds a Graphviz topology under config/.

Merge Risk: 🟡 Moderate · up to The optional probe can pass its outage check without observing a new alert, and cleanup can leave the restarted VM running. Fix both before relying on the probe run. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The new functionality is confined to a disposable local lab, with protected management access and isolated CMR links. However, restarting the remote router loses its cleanup registration, so completion can leave an unmanaged router process running. Retained concerns

- Line 86: Update the outage assertion in the `until` call to require new
events: capture the `lab-down` alert count and matching `DOWN cmr-remote`
webhook count before `remote.stop()`, then wait until both counts have increased
from their captured values.
- Around line 88-90: After QuickCHR.start returns the restarted handle, replace
the original handle in the teardown tracking used by runExample with remote.
Ensure cleanup stops the returned handle, whose PID reflects the restarted VM,
rather than relying only on updates to lab.remote or lab.all[2].

Learning: When a PowerShell script in examples dot-sources examples/common.ps1, set $ErrorActionPreference = 'Stop' before loading it. This ensures failures during loading terminate execution; setting the preference inside common.ps1 is too late if dot-sourcing fails. Because Start-Job runs in a separate process, set the required error preference explicitly inside each job script block as well.

#183) Review fixes for #184: - Teardown looks each lab machine up by name. After `--probe` restarts the remote, the tracked handle's remove() deleted the machine state without stopping the new QEMU. Earlier runs leaked that process while `quickchr list` looked clean. - Ctrl-C at any point requests cancellation. The next lab step throws, and the VMs are removed once any in-flight start finishes. A second Ctrl-C removes them immediately. - A library-mode start that fails after spawning QEMU removes its machine. - The outage check counts DOWN alerts and webhooks from before the stop, because the probes' controller reboot can fire them first. - Probe observations are recorded as they are made, so a failing probe still reports what it saw. - A transport error on /system/backup/load (RouterOS reboots) no longer aborts the probe; HTTP errors still do. The topology diagram now also shows the CMR settings, alert rules, upgrade rule, layout and webhook path. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
