- mgmt-console-api: custom-rule + alert operational learnings (1.0 operators do not evaluate at queryLang 2.0 and silently never fire; alerts inherit rule description; events/correlation vs scheduled alert-surface split; scheduled activation latency + PUT re-activation) - sdl-api: HEC ingestion notes (flat dotted keys beat nested JSON; HEC drives all three custom-rule types on AI-SIEM) - powerquery: 1.0-vs-2.0 operator note (ContainsCIS -> contains:anycase) - sdl-solutions: DaC playbook metadata-into-description footer + HEC end-to-end validation recipe; scaffold engine folds metadata into a [DaC] footer; events example uses contains:anycase - version bump to 1.2.8, rebuilt dist bundles
- monitors/requirements.txt: replace version-only pins with a fully hash-locked resolution (direct + transitive, 24 packages) generated from requirements.in via pip-compile --generate-hashes; verified installable under --require-hashes. - monitors/requirements.in: add regeneration source. - .gitignore: ignore __pycache__/ and *.pyc/*.pyo. - remove accidentally-tracked monitors/__pycache__/*.pyc bytecode. - README: note the lock is hash-pinned and how to regenerate.

Summary
Captures the detection-as-code validation learnings from live testing into the relevant skills, and bumps the plugin to 1.2.8. No new solution, this hardens
sdl-solutionsDaC plus three sibling skills with confirmed-live behaviours.Learnings added
mgmt-console-api(custom detection rules + alerts): 1.0 operators (ContainsCIS) are accepted at create but do not evaluate underqueryLang 2.0and the rule silently never fires (usecontains:anycase); alerts inherit the ruledescription;events/correlationalerts appear in/cloud-detection/alertswhile scheduled alerts surface only in UAM; scheduled rules sit inActivating(up to ~1h) and every PUT resets activation.sdl-api(HEC): use flat dotted keys ({"event.category":"firewall"}), nested OCSF drops reserved namespaces; HEC data drives all three custom-rule types on an AI-SIEM tenant.powerquery: 1.0-vs-2.0 operator note in the operator reference.sdl-solutions(Detection-as-Code): the metadata-into-description[DaC]footer pattern and an end-to-end HEC validation recipe. Scaffold updated:dac_sync.pyfolds[metadata](mitre/tactics/tags/owner) into an idempotent footer,rule.schema.jsondocuments the keys, and the events example usescontains:anycase.Testing
All learnings were confirmed live on an AI-SIEM tenant: all three DaC rule types were enabled, fired from HEC-simulated data, and each alert carried the
[DaC] MITRE/tactics/tags/ownerfooter.Release
