From triage of run 33923190220. Each fix is independently complete. penpot: ansible templates delegate_to before the task's merged when, and AnsibleUndefinedVariable escapes get_delegated_vars_and_hostname. PENPOT_BACKEND_HOST_NODE is set only by the resolve include, so the bootstrap task hard-failed on every host that include skipped instead of skipping with it. A block-level when cannot prevent this; move the tasks into a dynamic include. matrix: the MDAD reconfigure looked for volume matrix_matrix_mdad_state (real name matrix_mdad_state) and container matrix-mdad (real name matrix). Both if-bodies were skipped while the task still reported changed, so a rotated S3 secret never reached synapse and every media write got SignatureDoesNotMatch. Move the shell into its own script and pass the real names through the environment. Also add no_log to the vars.yml render, whose diff printed 16 secrets in cleartext. n8n: when the settings file and N8N_ENCRYPTION_KEY disagree, oclif's findCommand throws for every command, so 'n8n export:credentials' is unreachable in exactly the state that would need it. The re-key is one-way; pin it rotatable: false. swarm-drill: distros.sh sees only rc=124 and cannot tell a wedged deploy from one the sweep deadline cut short. Say so where the governor caps it.

Swarm test routine 🔁
Sequenced steps of the swarm lab run. Bring-up and the chaos phase are
workflow steps; the per-round loop in between is driven by
utils.tests.swarm.matrix (one round per variant of the
primary app). Highlighted boxes (⚡) are the moments a backup-executing
systemd unit actually starts. See ../README.md for
topology, naming SPOTs and helpers; the DR drill's own steps are
documented in backup/README.md.
