# There used to be four of them — ecosystem.config.cjs, .light., .mac.light. and
# a .profile. that the others derived from. A profile deriving from a full list
# means the full list has to exist, which means every plugin's process is
# described in the repository whether or not anybody installed it, and a test had
# to assert that the two files still agreed with each other.
#
# One generated file removes all of that. It describes exactly the processes this
# install runs, it is written once at setup, and nothing in git can drift from
# it. A plugin adds its own entry when it is installed.
#
# ── Why .cjs and not .js ──
#
# PM2's own convention is ecosystem.config.js, and it would be wrong here:
# package.json declares "type": "module", so a .js file in this directory is ESM
# and `module.exports` throws "module is not defined in ES module scope". PM2
# require()s the config, so the extension has to say CommonJS out loud.

# `officer-claude-code` was `officer-agent` until 2026-08-13. The old name said
# nothing about what it runs, and it sits beside officer-anthropic-proxy — which
# is a different process doing a different job — so "the agent" was ambiguous
# exactly where it mattered. It spawns `claude`; the name says so now.

  # resolves empty — so an install that never sets an APNs key runs it as a no-op rather than crash-looping.
