#5037 "Secrets at rest and in run output: webhook URL and git token encrypted, askpass via env, secret values scrubbed from logs". - webhook.url joins SECRET_KEYS; existing values are sealed at startup by migrate_plaintext_secrets. Settings -> Notifications no longer echoes the URL: it names the saved host, keeps it when left blank, and has a Remove box. - Git source http_token is sealed inside ansible.sources on save and at startup, opened in get_sources, and counted by the undecryptable-secrets scan as ansible.sources[<name>].http_token. - The askpass script holds no token: git runs it with STEWARD_GIT_TOKEN in its environment and printf prints it as data. - The executor masks every secret the run is handed (become/vault passwords, bootstrap passwords, sensitive run vars, and the per-host agent tokens the host_agent plugin now passes as redact) in each line before it is broadcast, logged or stored. - Bundled "Write agent config" tasks are no_log; a test fails if any bundled task templating steward_token lacks it.
