The doc-drift sample-stack fixtures declared AWS::Serverless::Function with no
Properties; cfn-lint's SAM transform errored (HIGH). Added minimal valid
Properties (Handler/Runtime/InlineCode). Pre-existing on main — #19 pushed with
--no-verify (xargs overflow) and CI runs no cfn-lint, so it slipped through.
doc-drift still detects the stack (keys on template presence).
Register doc-drift, aws-posture, plan-groomer, confluence-doc (weekly cadence)
alongside compliance-drift + dependency-cve (nightly). The coordinator canary
suite now runs all 6 roles' canaries (all PASS) under the one shared budget +
versioned rotation/coverage state; --squeeze-dry-run still proves defer-not-drop
+ COVERAGE alarm. Central integration after the parallel Phase-3/4 PRs landed.
