Root cause: Removing ea: from config.yaml broke 4 call sites in
optimizer_loop.py (_execute_run, _build_components) and main.py that
still read cfg['ea']. Server started but MT5 never launched.
Fixes:
config.yaml - Restored ea: block as bridge for legacy callers
optimizer_loop.py - _build_components: loads EARegistry, creates
IniBuilder(schema=schema) instead of manifest path
_execute_run: uses self._profile.{name,symbol,tf}
instead of cfg['ea']; passes profile to runner.run()
mt5/runner.py - Validation + TradeLog now use EAProfile data when
profile is provided (legacy fallback preserved)
Tested:
7/7 pre-flight checks pass (config, registry, schema, IniBuilder, runner,
MutationEngine, OptimizerLoop._build_components)
Live browser test: Start clicked → MT5 launched → logs appeared → Reports
page loaded (9 cards) → Back to dashboard navigated in-tab
System fully operational
