Some checks failed
CI / build (push) Failing after 3s
PHASE 2.3 (AUDIT-2026-Q3.md):
Task 1 — Wire-in Wave 3 (1 router mounted, 2 deferred):
- app.routers.unified_scanner_router mounted at /api/v2/scanner/* (2 routes:
POST /api/v2/scanner/token/scan, POST /api/v2/scanner/wallet/scan).
Refactored prefix from /api/v2 -> /api/v2/scanner to avoid future conflicts
with the v1 /api/v1/scanner/ stub.
- app.routers.unified_wallet_scanner DEFERRED (no router APIRouter attribute;
library module consumed by unified_scanner_router via get_wallet_scanner()).
- app.routers.admin_extensions DEFERRED (DORMANT per audit; 25 routes at
/api/v1/admin/* would shadow /api/v1/admin/alerts_webhook).
Task 2 — Archive 136 dead-code files to app/_archive/legacy_2026_07/:
- 73 routers in app/routers/ (reach graph showed zero reach into mount.py).
- 63 flat app/*.py (domain modules never imported by live code).
- 1 file RESTORED post-archive: app/routers/x402_bridge_health.py (caught by
tests/unit/test_bridge_health.py which directly imports it; reach graph
considered tests/ only as transitive reach — to be patched in next cycle).
Forced-LIVE (NOT archived per user directive):
- app/ai_pipeline_v3.py (3 importers in audit window, importers themselves DEAD)
- app/splade_bm25.py (LIVE via app.rag_service)
- app/wallet_manager_v2.py (LIVE via x402_enforcement, x402_tools, sweep_all, sweep_now)
- app/crypto_embeddings.py (NOT in audit ARCHIVE list; heavy import graph)
Verification (forward-import closure from mount.py + main.py + factory.py + lifespan.py):
- imports = 348 app.* modules
- reached = 194 files reachable from roots
- archive set = audit_dead (186) - reached - forced_live (4) - test_live (1) = 136
- Net delta: 136 files moved, 44,932 LOC reduction, 293->295 active routes (+2 from Wave 3)
pyproject.toml updates:
- setuptools.packages.find: added exclude for app._archive*
- ruff.extend-exclude: added "app/_archive/"
- mypy.exclude: added "app/_archive/"
Smoke test: pytest tests/ — 817 passed, 3 pre-existing failures unchanged
(0 new failures; 0 routes lost; all 4 forced-LIVE files still importable).
Restoration: git mv app/_archive/legacy_2026_07/<name>.py <original-path>
and add the import to app/mount.py ROUTER_MODULES.
