Phase 5B of startup_speedup_20260606 track.
src/theme_2.py had 3 top-level NERV imports:
from src import theme_nerv
from src.theme_nerv import DATA_GREEN
from src.theme_nerv_fx import CRTFilter, AlertPulsing, StatusFlicker
And 3 module-level FX object instantiations:
_crt_filter = CRTFilter()
_alert_pulsing = AlertPulsing()
_status_flicker = StatusFlicker()
ALL removed. The 3 use sites now lookup via _require_warmed:
- apply() NERV branch: theme_nerv = _require_warmed('src.theme_nerv')
- ai_text_color(): theme_nerv = _require_warmed('src.theme_nerv')
(then uses theme_nerv.DATA_GREEN)
- render_post_fx(): theme_nerv_fx = _require_warmed('src.theme_nerv_fx')
(then creates FX objects locally per-call)
The _status_flicker was instantiated but never used (dead code path;
the StatusFlicker class is still importable via theme_nerv_fx but not
auto-constructed in theme_2.py).
TESTS:
- tests/test_theme_2_no_top_level_nerv.py: 4/4 PASS (all RED -> GREEN)
- tests/test_theme.py, test_theme_nerv.py, test_theme_nerv_fx.py,
test_theme_models.py: 21/21 PASS (no breakage)
EFFECTIVENESS: import src.theme_2 no longer triggers src.theme_nerv or
src.theme_nerv_fx (~485ms combined). For users on default theme, these
are NEVER loaded. For NERV users, the warmup pre-loads on _io_pool and
the lookup is O(1).
NEXT: Phase 5C (markdown table) follows same TDD pattern.
