-# Example: Release vault item schema
-#
-# This example demonstrates the release vault item schema for creating
-# versioned releases with vault-gated approval.
-#
-# The release formula tags Forgejo main, pushes to mirrors, builds and
-# tags the agents Docker image, and restarts agent containers.
-#
-# Example vault item (auto-generated by `disinto release v1.2.0`):
-#
-#   id = "release-v120"
-#   formula = "release"
-#   context = "Release v1.2.0"
-#   secrets = []
-#   mounts = ["ssh"]
-#
-# Steps executed by the release formula:
-#   1. preflight - Validate prerequisites (version, FORGE_TOKEN, Docker)
-#   2. tag-main - Create tag on Forgejo main via API
-#   3. push-mirrors - Push tag to Codeberg and GitHub mirrors
-#   4. build-image - Build agents Docker image with --no-cache
-#   5. tag-image - Tag image with version (disinto-agents:v1.2.0)
-#   6. restart-agents - Restart agent containers with new image
-#   7. commit-result - Write release result to tracking file

-id = "release-v120"

-# Optional: specify a larger model for complex release logic
