ci.yml

# The build gate — build + unit tests on every pull request and every push to main.
#
# Only `pull_request` and `push` are used. A fork's pull-request run gets a read-only token and no
# secrets, which is what makes it safe to run a stranger's code here at all. `pull_request_target`
# and `workflow_run` would run in this repository's context with access to secrets, and neither is
# used anywhere in this repository for that reason.
#
# The weekly schedule catches SDK and dependency drift in a quiet week, when no push would.
#
# Build + test operate on Stratara.Publish.slnf, the same solution filter the release workflow packs
# from. Integration suites (*IntegrationTests) need Docker and run in integration.yml.
