app/_archive/legacy_2026_07

Archived 2026-07-06 as part of AUDIT-2026-Q3.md Phase 2.3 + P2.4.

This directory contains 136 .py files moved out of app/ and app/routers/ because they had zero reach into the running application at the time of the audit. Reach was verified across 5 surfaces via a forward-import closure from app/mount.py, app/main.py, app/factory.py, and app/core/lifespan.py:

1. NOT in app/mount.py mount expressions
2. NOT statically imported by any .py in app/, tests/, scripts/
3. NOT dynamically loaded by app/core/lifespan.py
4. NOT referenced as a string anywhere in *.yaml/*.yml/*.toml/*.json
5. NOT in the lifecycle always-loaded set

Composition (137 files)

Bucket	Count	Notes
app/*.py (flat)	63	Domain-specific modules never imported
app/routers/*.py	73	Routers never mounted and not imported (1 restored, see below)
Total	137	—

Total LOC moved: 44,932 lines (reduces active tree by ~25%).

Reach-graph re-verification (over 4 surfaces)

imports      = 348 app.* modules statically imported
ref_files    = 51 files with string references
closure      = forward BFS from mount.py + main.py + factory.py + lifespan.py
reached      = 194 files reachable from roots
archive set  = audit_dead (186) - reached - forced_live (4 stale items) - test_live (1) = 136

Restored post-archive (test dependency surfaced by smoke test)

• app/routers/x402_bridge_health.py — restored 2026-07-07. The reach graph showed it as DEAD, but tests/unit/test_bridge_health.py has 7 direct imports of it. The audit's reach graph considered tests/ only as a transitive reach, not as a source of LIVE. The smoke test caught the regression and we restored. Reach graph will be patched to include tests/*.py as roots in the next audit cycle.

Forced-LIVE (NOT archived per user directive)

The reach graph would have archived these, but the user listed them as LIVE and asked us to DEFER with a note:

• app/ai_pipeline_v3.py — imported by app/unified_wallet_scanner.py and app/news_intelligence.py. The reach graph shows those importers are themselves DEAD, so ai_pipeline_v3 is also technically DEAD. But kept per user instruction (3 importers in the audit reach-graph window).
• app/splade_bm25.py — imported by app/rag_service.py (LIVE).
• app/wallet_manager_v2.py — imported by app/routers/wallet_manager_v2.py, app/routers/x402_enforcement.py, app/routers/x402_tools.py, app/sweep_all.py, app/sweep_now.py, scripts/setup_x402_rotation.py. Has a top-level NameError (Bip44Coins) but the import works because the failing line is in a function body only executed at runtime.
• app/crypto_embeddings.py — NOT in the audit ARCHIVE list at all (the audit had a stale dead-list entry that was already KEEP). Heavy import graph: rag_service, bundle_cluster_rag, rag/embedder, supabase_vector, rugmaps_ai, scam_sources, intel_feed_pipeline, rag_agentic, ragas_eval, tests/manual/test_rag.py, scripts/ingest_sigmod_fast.py.

Wave 3 (newly mounted, NOT archived)

• app/routers/unified_scanner_router.py — mounted 2026-07-07 at /api/v2/scanner/{token,wallet}/scan (2 routes). Reach graph would have archived it; the new mount entry in app/mount.py makes it LIVE.
• app/routers/unified_wallet_scanner.py — DEFERRED (no router APIRouter attribute; library consumed by unified_scanner_router).
• app/routers/admin_extensions.py — DORMANT per audit (darkroom-specific, 25 routes at /api/v1/admin/*); would shadow /api/v1/admin/alerts_webhook.

How to restore

These files are kept in git history under the path app/_archive/legacy_2026_07/. To restore any of them:

cd /srv/work/repos/rmi-backend
git mv app/_archive/legacy_2026_07/<name>.py app/routers/   # or app/
# Then add the import to app/mount.py ROUTER_MODULES
git commit -m "restore <name>.py from legacy archive"
git push origin main

git log --all --oneline -- app/_archive/ shows every move. We did NOT rewrite history (would break external mirrors at github.com, gitlab.com, huggingface.co).

Why archive, not delete

Git retains the full history. git log --all --oneline -- app/_archive/ shows every move. The archive path itself is excluded from:

• pytest discovery — pyproject.toml tool.pytest.ini_options testpaths = ["tests"] does not traverse app/.
• ruff — [tool.ruff] extend-exclude = [..., "app/_archive/"] (added 2026-07-07).
• mypy — [tool.mypy] exclude = [..., "app/_archive/"] (added 2026-07-07).
• setuptools — [tool.setuptools.packages.find] exclude = ["app._archive*"] (added 2026-07-07).

The audit doc at /home/dev/pry/rmi-final-deadcode-2026-07-06.md lists every file with the original path and recommendation.
