Was `0 12 * * 0` (Sun 12:00 UTC) — patch releases waited up to 6 days before the chain picked them up. Now `0 12 * * *` (daily 12:00 UTC, still outside kured's 02:00-06:00 London window). Concurrency is bounded by Forbid + deterministic job-name idempotency (the detection job exits early if a preflight Job for the same target already exists), so back-to-back days can't pile up parallel runs. - stacks/k8s-version-upgrade/main.tf: var.schedule default + rationale comment - scripts/upgrade_state.sh: rename next_sunday_noon_utc -> next_daily_noon_utc (now returns "Tue 2026-05-19 12:00 UTC" form); change "(Sun cron)" label to "(daily cron)" - .claude/skills/upgrade-state/SKILL.md: cadence column + frontmatter Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

# The three pipelines:
|
|
# 1. Apps — Keel polls registries hourly and rolls Deployments tagged
|
|
# keel.sh/policy. Metrics on container :9300/metrics.
|
|
# 2. OS — unattended-upgrades patches in-release per node; kured
|
|
# reboots within a daily 02:00-06:00 London window.
|
|
# 3. K8s — k8s-version-check CronJob (Sun 12:00 UTC) detects new
|
|
# kubeadm patch/minor releases; Job-chain drains+upgrades
|
|
# node-by-node. Pushgateway holds k8s_upgrade_* gauges.
