+# Surface latent vet/test errors on main by running the full Platform-Go
+# suite on a weekly cron regardless of whether the last push touched
+# workspace-server/.
+#
+# Background: ci.yml's `platform-build` job gates real work on
+# `if: needs.changes.outputs.platform == 'true'`. When no push touches
+# workspace-server/, the skip fires and the suite never executes on main.
+# Latent vet errors and test flakes can sit for weeks undetected.
+#
+# This workflow runs the full suite (build, vet, golangci-lint, tests with
+# coverage) every Monday at 04:17 UTC. Results are posted as commit statuses
+# but continue-on-error: true means they never block anything — they're
+# purely a noise-reduction signal for when the next workspace-server push
+# lands and would otherwise trigger the first real suite run.
+#
+# Why 04:17 UTC on Monday: off-peak, before the weekly sprint cycle starts.
