	name: ci

	# Builds, tests and lints everything that CAN be checked on a hosted runner.
	#
	# WHY THIS EXISTS SEPARATELY FROM release.yml. The release workflow only runs on a tag, so until
	# now the first time the installer was compiled for Windows was during the release itself — which
	# is the worst possible moment to discover it does not compile. This runs the same build on every
	# change, so a tag is a formality rather than a gamble.
	#
	# The ARM LINK is still not done here: it needs a glibc-2.23 + libc++-3.9.0 cross toolchain matched
	# to the player's runtime, which is real machinery to maintain on a runner for little gain. The
	# device binaries are built by a maintainer and committed under cinder-home/dist/, and
	# `tools/release.sh` verifies that committed payload byte-for-byte against a fresh build before it
	# will tag.
	#
	# But "we cannot LINK for ARM here" was quietly being read as "we cannot check the C++ at all", and
	# that left ~19,400 lines of C and C++ — the code that runs as root, owns the boot path and drives
	# the closed Sony services — with no automated gate of any kind (docs/SHORTCOMINGS.md §A1). The
	# `native` job below closes most of that with a stock toolchain and about a minute of runner time.
	#
	# ── TRIGGERS: ONE RUN PER CHANGE, NOT TWO ───────────────────────────────────────────────────────
	# This used to be `push: ["**"]` PLUS `pull_request`, and for a branch with a PR open — which is
	# every branch that matters — BOTH fired, so every push ran the whole matrix TWICE. Eight jobs
	# where four were wanted, for the life of the repo.
	#
	# Now `pull_request` covers branches and `push` covers main. A branch with no PR gets no CI; that
	# is the deliberate trade, and `workflow_dispatch` is the escape hatch when you want a run anyway.

	# older, and the two disagree about `#!/system/xbin/busybox sh`. A lint gate whose version

	# v0.1.7 is why. release.yml verifies the payload against a sha256 manifest, and that gate ran

	# immediately: `windows-latest` checks out with core.autocrlf=true, which rewrote the two text
	# members of the payload, so their hashes no longer matched. Nothing was stale — the bytes were
	# changed in transit — but the release was already cut before anything noticed.

	# July and nothing automatic ran it (SHORTCOMINGS.md §A3), which for the one script whose
	# failure mode is "brick" is the wrong way round. About fifteen seconds — the cases that
	# exercise the crash supervisor have to actually wait for its backoff.
	#
	# Runs here as a NON-root user, which matters: one case makes /data/cinder unwritable with
	# chmod, and chmod does not bind uid 0 — on a root shell that case silently reports a failure

	# go red. Both were clean of vulnerabilities when this job was added (2026-09-01).
