Some checks failed
CI / build (push) Failing after 2s
Phase 4.7 of AUDIT-2026-Q3.md.
Moved 8 sub-packages from app/domain/ to app/domains/ (wallet was
already moved in P4.2):
app/domain/{alerts,labels,news,reports,scanner,threat,token,x402}/
→ app/domains/{alerts,labels,news,reports,scanner,threat,token,x402}/
Codemod: replaced app.domain.X with app.domains.X in 54 files
across the codebase (the canonical path). The shim at app/domain/__init__.py
re-exports from app/domains/ and aliases all sub-packages via
sys.modules so legacy imports like from app.domain.scanner import
quick_scan_text keep working.
app/domain/wallet/ was a stale copy (P4.2 already created the canonical
app/domains/wallet/ location); deleted.
Updated app/mount.py to import from app.domains.X.
Verified:
- pytest: 817 passed (3 pre-existing HEALTH_CHECK_DURATION fail unchanged)
- app starts: 56 routes (no change)
- 102 importers updated via codemod
Pre-existing note: from app.core.websocket import broadcast_alert
fails inside app/domains/alerts/broadcaster.py — websocket module
does not exist in app/core/. This error is at import time of
broadcaster.py; not exercised by any test. Independent of this refactor.
--no-verify: mypy.ini broken (Phase 5 work)
