# Python Retirement Readiness (post-P1)

Classification of every Python component still present. Evidence: prod-host
`owner=` dispatch log (OBSERVED), AuxServiceMap/PythonContractMap scouts,
container `entrypoint.sh`. **P2 rollback stays hot regardless** (do NOT remove
rollback-to-python-p2.sh, :p2-rollback image b1b929953f, profile 39bb3e83).

## A. LIVE PRODUCTION REQUIRED (still owns behavior in the live flow)
| Component | Role | Rust status | Retire when |
|---|---|---|---|
| oracle utas_server.py (:8199) NON-ECONOMY | account/sync, hub, club/stats, clientdata, userMassInfo envelope | 5 routes migrated (accountinfo/settings/leaderboards-options/match-reset/phishing); hub/club-stats/clientdata/account-sync still proxied | remaining non-economy routes migrated + operator-validated |
| blaze_responder_v3b.py (:42130 Blaze) | FUT Blaze transport | Rust openfut-blaze-host COMPLETE, gate-proven (Gate 10) | container cutover (operator-gated deploy) |
| blaze_responder_v3b.py (:42127 redirector TLS) | first-hop TLS redirect | Rust openfut-redirector-host COMPLETE (OpenSSL) | container cutover + cert consistency |
| roster_server.py (:8081) | roster-update XML | Rust openfut-roster-host COMPLETE (unit-only) | container cutover |
| pow_server.py (:8094/:8080) | Proof-of-Work / content | NO Rust crate; 58 templates, bodies un-reversed | needs Rust host + body RE (BLOCKED) |

## B. ORACLE ONLY (reference / differential, not production authority)
- utas_server.py economy handlers: now oracle-only (economy is Rust; Python economy hits = 0). Used by
  `economy_differential.rs` as the parity oracle. KEEP.
- fut_store.py / fut_accounts.py / fut_consumables.py: reference models + Ghidra-derived taxonomy source. KEEP.

## C. MIGRATION TOOL ONLY (offline)
- scripts/*.py (seed_fifa17_cards.py, utas-observe/mutate/diff, check-*). KEEP (dev tooling).
- fifa17-recon/tools/db_dump.py etc.: table extraction. KEEP.

## D. ROLLBACK ONLY (hot, DO NOT REMOVE)
- rollback-to-python-p2.sh; image openfut-fut-backend:p2-rollback (b1b929953f) + :dev; profile 39bb3e83;
  compose/env backup; tuple OPENFUT_SERVERS="blaze roster utas pow".

## E. DEAD (advertised but not followed in current FIFA17 flow)
- Nucleus /connect/token stub (:42131): 0 live hits across Gate 5-10 (client never POSTs). Keep the ADVERTISED
  URL so the client can't reach real EA, but no migration needed. No Rust listener required.
- fifa-blaze (FIFA23 capture stub), openfut-bridge (FIFA23): retired lineage, not in FIFA17 flow.

## Retirement gating
1. Migrate remaining non-economy oracle routes to Rust (hub/club-stats/clientdata/account-sync) — then oracle
   is oracle-only (class B).
2. Deploy Rust blaze/roster/redirector via container cutover (operator-gated) — then those Python responders
   are class D/E only.
3. POW: build Rust host + reverse bodies (largest blocker) OR keep Python POW as class A indefinitely.
4. Only after a long stable window: consider retiring the P2 rollback (separate explicit decision — NOT now).
