One credential set per customer (UUID + 32-byte root relay key + shortId)
lives on the customer record; node bindings no longer store credentials.
SS2022 user keys derive deterministically from the root key by method
length (16/24/32-byte prefix), so a single password serves every protocol,
matching 3x-ui's per-client credential model. Reality public keys stay a
node property and are shown per binding in the credentials pane.
- store: load-time convergence — first binding's set wins; a converged
password that is not a 32-byte root key is regenerated (uuid/shortId
preserved); bindings are stripped; idempotent, covered by tests
- deploy: the orchestrator stamps the customer's set onto a build copy;
subscriptions resolve the same set; the derivation applies in both the
inbound builder and the URI builder (verified live: Alice's N1 link is
byte-identical to the pre-change seed expectation, her N2 user key is
exactly the root key's 16-byte prefix)
- API: GET /api/customers/:id/credentials returns {credentials, bindings};
regenerate is now POST /api/customers/:id/credentials/regenerate and
rotates the whole set, rebuilding every deployed node of the customer
- UI: credentials pane shows the single shared set plus per-binding
node/protocol/Reality-public-key rows
- golden subscriptions fixture regenerated under one shared set (RF and
SS entries byte-identical to before; five entries audited by hand)
- golden baseline re-captured for the new shapes; difftest normalizer now
treats a base64 root key's prefix-truncation encodings and the Surge
'='-mangled variants as the same secret
