…talhelper-to-topf Learned migrating a two-node Talos v1.13.8 cluster (NAT'd worker, Argo CD bootstrapped via inlineManifests) and verified against the last talhelper render: - drop the stale "no v1.14 multi-doc support" claim; keep "migrate on the running format, upgrade later" for the zero-diff reason - new verify step: diff `talhelper genconfig` against `topf render`, check `topf schematic-ids`, read `topf apply --dry-run` as a textual diff (document order shows up, and so does never-applied talhelper drift) - gotchas: hostname is not derived from `host`; `inlineManifests[].contents: "@./file"` has no include equivalent (wrap via yq, or vals ref+file:// with redaction caveat); `skipEnvsubst` is moot; `.tpl` parses YAML comments; role-level schematics and node overrides -> one templated schematic; keyed lists still merge across scopes; TOPF dials each node directly, no apid proxying - secrets hygiene: `.sops.yaml` rule encrypting only `data`, `sops set` move without plaintext on disk, `.gitignore` clusterconfig/ -> output/ - field-mapping: inlineManifests include note, role schematics row, hostname row Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Sorry, claude auto mode was a bit ambitious
TL;DR:
This PR still includes some nice findings for making the migration a bit more "reliable"
