name: Install & Update E2E

# Can a user on a released version get to this commit?
#
# The support matrix -- every {os, install-method, update-method} combination
# a user could be on -- lives in scripts/sandbox/generate-e2e-matrix.mjs.
# generate-matrix expands it against the picked release tags into one leg
# per {combination, tag}, split into one matrix job per OS:
#
#   Matrix: linux     a real curl|bash install in the bubblewrap sandbox
#                     (install-e2e-run.yml)
#   Matrix: windows   the real desktop user flow: website Hermes-Setup.exe
#                     clicked by AutoHotkey, update via the app, Playwright
#                     clicking "Update now" (install-e2e-windows-run.yml)
#   Matrix: macos     no driver yet (install-e2e-macos-run.yml)
#
# Every combination is dispatched to its OS's run workflow; the run
# workflow natively skips (grey) what its driver cannot run yet -- an
# unimplemented method pair, or a starting tag that predates the surface
# under test (pick-releases annotates each tag with what its tree ships,
# e.g. whether the desktop app exists yet). Capability knowledge lives
# next to each driver, never here and never in the generator: declaring a
# method is a spec edit, implementing one is flipping the run workflow's
# gate.
#
# The starting versions are chosen at runtime from the repo's release tags
# (scripts/sandbox/pick-release-tags.sh): newest, oldest, and a spread
# between. A hardcoded list would stop covering the newest release the day
# after it ships, and would pin an "oldest" that nobody still runs.
#
# Triggers:
#   * every 12 hours, so upstream drift (a new uv, a Node bump, a PyPI change)
#     surfaces on a schedule rather than in someone's review cycle;
#   * when a release tag is created -- the moment the set of versions users can
#     update FROM changes, and the moment a broken updater would strand them;
#   * manually, where you can pick the route and how many releases to sample.
#
# Deliberately NOT on pull_request: a leg takes ~11 minutes of real toolchain
# installation, and the matrix multiplies that. Updating is release-shaped work,
# so it is gated on releases and the clock instead.
