main.py became main/ with __main__.py, so the invocation string baked into
run.sh and the systemd unit (`python -m steam_backlog_enforcer.main`) stays
byte-identical and nothing needs redeploying. Commands are grouped into
sibling modules (status, install, picks, abandon, misc), with _shared.py as
a leaf holding the lock helpers and constants both need, and _registry.py
holding the command tables. main/__init__.py keeps every public and private
name importable, so `from steam_backlog_enforcer.main import X` is unchanged.
The subtle part is patch targets. The test suite builds them as
f"{PKG}.{name}", so a grep for the literal module path found nothing -- but
once a command moves to a submodule it resolves its dependencies from that
module's globals, and patching the main package's re-export silently stops
biting. Measured which of the 36 patched symbols moved: 8 could have passed
vacuously. Rather than repair PKG per class, the five test_main*.py files
(all cap violators anyway) were regrouped to mirror the production modules,
so each file has exactly one correct PKG. Verified by mutation: breaking a
line in status/misc/picks/_shared each makes the corresponding tests fail.
test_web_server.py patched main_mod.serve, which no longer intercepts
cmd_serve; repointed at main.misc and confirmed it fails when the call is
removed. Added tests for the __main__ shim, which coverage would otherwise
report at 0% under fail_under = 100.
Shared test builders live in tests/_main_helpers.py, reachable because the
Phase 0 name-tests-test exclude allows tests/_*.py.
1290 tests pass; every main/ module reports 100% coverage; `main`, `status`,
`bogus` and `--status` produce byte-identical output and exit codes to
pre-refactor. 55 -> 49 files over the cap.
