The FUT hub failed to load with "An error occurred downloading the FUT Squad
Update" because the client dials the roster (https://<advertise>:8081) and the
redirector BY IP, while the served certificate carried DNS SANs only
(winter15.gosredirector.ea.com + wildcards). The client aborts that handshake with
fatal certificate_unknown. Root cause and evidence in
docs/FIFA17_FUT_SQUAD_UPDATE_TLS.md (commit 082246c): a wire capture shows the client
offering TLS1.2 with RSA suites, the server selecting them, then rejecting the cert —
and autopatch demonstrably patched both ProtoSSL gates in that process, so this
validation path is NOT one of the two the client-side patch covers. The SAN is the fix.
Three generators produced the cert and none put the advertised IP in the SAN:
* docker entrypoint.sh — the production path. The advertised IP is a RUNTIME value
(OPENFUT_ADVERTISE), unknown at image-build time, so the cert is now reconciled at
startup: reissued with IP:$ADV,IP:127.0.0.1 in the SAN only when the current cert
lacks it. That makes a restart reuse the same cert (no per-start fingerprint churn,
which would otherwise recreate the Aug-13 surprise) and self-heal if $ADV changes.
* Dockerfile — installs openssl unconditionally so the entrypoint can reissue at
runtime (previously it was dropped with the apt lists), and bakes a loopback-IP
baseline cert so a plain `docker build` still yields a usable image.
* openfut-fut.sh — the local orchestrator. ensure_cert now defaults the SAN IP to this
host's primary LAN IP (OPENFUT_ADVERTISE overrides) and reissues when the cert lacks
it, instead of only generating when the file is absent.
Verified without the client, which is the strongest evidence obtainable here: a
verifying TLS client checking the cert BY IP rejects the old DNS-only cert ("IP address
mismatch, certificate is not valid for '10.10.0.120'") and accepts the new
IP-bearing cert; and the entrypoint reconcile is idempotent end to end — an old cert is
reissued to carry IP:$ADV, a simulated restart leaves the fingerprint unchanged, and
the final SAN carries both the advertised and loopback IPs.
Live confirmation needs the production container rebuilt with OPENFUT_ADVERTISE set
(operator-gated); production is otherwise untouched.
entrypoint.sh carries unrelated pre-existing uncommitted work (env-based component
selection) that is not on any branch; only the cert-reconcile block is committed here,
and that work is left intact in the working tree.
Cheap insurance, explicitly not the real check -- the semantic tests in
deployment_config.rs are what prove propagation, using two TEST-NET addresses
and bind != advertise. This grep only stops the lab subnet reappearing months
from now when the reasoning has been forgotten.
Deployment config legitimately contains real addresses and lives in gitignored
files, so it is never scanned. The frozen baseline doc is allowlisted BY PATH:
it records what a past deployment actually was, and rewriting it would falsify
the record.
Also swapped the lab IP for a TEST-NET placeholder in the usage examples and
error messages of compose/entrypoint/client_arm. Those were already correct
architecture -- every one requires the address via ${VAR:?} -- but using the
real lab IP as the example is the same 'happens to match our lab' smell, and
placeholders keep the tripwire allowlist near-empty.
Mutation-tested: adding a lab address to a source file makes it exit 1.

Freeze the running offline FUT backend into version control as
fifa17-recon/docker/fifa17-python/ - declarative and rebuildable from a
fresh checkout:
* OPENFUT_BIND / OPENFUT_ADVERTISE client/server split in the responders
(lsx, blaze, roster, utas, pow) + entrypoint.sh; OPENFUT_ADVERTISE is
required for remote mode (compose and entrypoint fail without it)
* docker-compose.yml reproducing the frozen baseline container exactly
(env, ports incl. the 8085->8080 POW-content remap, /state bind, restart)
* .env.example / .env for site config - the LAN IP is never hardcoded in source
* tools/ + data/ staged from openfut-fut-backend:python-baseline-2026-08-10,
verified byte-identical to the running container at freeze time
* client_arm.sh (the 105 client-side arming counterpart)
* Dockerfile bakes /app/SHA256SUMS.txt so any image is self-identifying
* docs/BASELINE-python-2026-08-10.md: frozen image/container/hash record,
restore instructions and rebuild-equivalence procedure
Secrets (redir key/cert, .env) and runtime state (docker/state) stay gitignored.
The live container is untouched pending the .105 launcher audit.
