+name: Regenerate Compiled Userscripts
+
+# Keeps every package's committed dist/*.user.js in sync with its TypeScript
+# source. dist/ is gitignored workspace-wide, but each package that publishes
+# a userscript force-commits its dist/*.user.js because Greasy Fork's sync
+# mechanism points at a stable raw.githubusercontent.com URL for it — see
+# graphite-to-github-button's history (4fc2806 renamed the raw .ts source
+# straight to this path without ever compiling it; this workflow exists so
+# that class of bug can't silently recur, now for every package, not just
+# that one).
+#
+# This repo is an Nx monorepo (yarn workspaces "packages/*", nx.json's
+# "build" target cached per-project). Rather than hardcoding one package's
+# build command, this always builds every project (`yarn run build`, i.e.
+# `nx run-many --target=build --all` — the same command ci.yml already
+# runs) and then stages whatever dist/*.user.js artifacts actually changed.
+# We intentionally skip `nx affected` here: computing a correct base/head
+# for a push-triggered affected run adds real complexity (fetch-depth,
+# first-push-to-a-branch edge cases), and with only a handful of packages a
+# full build is cheap. Revisit if the package count grows enough that this
+# stops being true.
+#
+# Loop safety (same pattern as nsheaps/github-actions' sync-plugin-specs
+# reusable workflow): two independent layers —
+#   1. The `paths` filter below matches any package's source/config files
+#      but excludes packages/**/dist/**, so the bot's own commit (which
+#      only touches dist/*.user.js files) can't re-trigger this workflow.
+#   2. The staging step only commits/pushes when the rebuild actually
+#      changed a tracked dist/*.user.js. Rebuilding from unchanged source
+#      is deterministic, so even a manual workflow_dispatch re-run right
+#      after a bot commit is a no-op.
+#
+# Only packages that actually produce a dist/*.user.js are ever staged —
+# packages/_template and packages/template build fine (same as in ci.yml)
+# but produce no *.user.js output, so they're naturally never touched by
+# the staging step below; no special-casing needed. Likewise,
+# github-actions-grafana-jump builds fine but has no *.user.js output of
+# its own yet either.
+#
+# main is protected by an active `require-pr` ruleset. This repo's
+# settings.yml grants the org automation GitHub App an always-exemption
+# (bypass_mode: always) on that ruleset — same as repo admins — so
+# authenticating as that app via checkout-as-app (the same action
+# apply-repo-settings.yaml uses) should let this push straight to main.
+# The branch+PR fallback below is kept as defense-in-depth: the live
+# ruleset hasn't been confirmed to actually reflect that settings.yml
+# exemption yet (see task #45's bypass_actors sync-gap investigation),
+# so if the push is still rejected, this falls back to the same
+# "try direct push, fall back to PR" idiom as nsheaps/github-actions'
+# sync-main-to-edge reusable workflow, opening a PR via that repo's
+# open-pr-if-needed composite action (idempotent — reuses an already-open PR
+# instead of piling up duplicates).
