 ## Persistent Shares
 
-Shared result links are stored in Redis when `NP_REDIS_URL` is enabled. The compose file maps Redis data to `./runtime/redis` and enables AOF/RDB persistence, so shares survive container recreation and service restarts. Back up or migrate `./runtime/redis` if you move the deployment.

 - Pair matrices are returned as a preview block to keep responses manageable.
 - The Docker image compiles ViennaRNA `RNAplot` from `rna/ViennaRNA-2.7.2.tar.gz` and embeds SVG structure plots into MFE results.
 - Multistrand MFE plots now use a split-strand layout by default when a structure contains `+`, with `RNAplot` retained as the fallback path.

+- The web UI supports Chinese and English switching, account-scoped cloud history, result export, share controls, and async polling for submitted jobs.
 - Docker now starts three services: `np-replica`, `np-worker`, and `redis`.

 - Static pages are served with ETag-based browser caching; JSON API responses remain uncached.
 - The force-directed structure viewer lazy-loads D3 only when that view is opened, so the initial page load is not blocked by the external CDN.
 - `/health` uses Redis queue length plus a running-job set instead of scanning every historical job on each poll.
+- Application login uses the public Authentik issuer at `https://auth.lihato.icu/` with Authorization Code + PKCE.
+- The current `npt` instance uses issuer `/application/o/nupack-account-npt/`, client `npt-replica-web`, callback `https://npt.lihato.icu/auth/callback`, and logout return `https://npt.lihato.icu/`.
+- For the independent `np` deployment on `100.64.0.11`, set `NP_OIDC_ISSUER=https://auth.lihato.icu/application/o/nupack-account/`, `NP_OIDC_CLIENT_ID=np-replica-web`, `NP_OIDC_REDIRECT_URI=https://np.lihato.icu/auth/callback`, and `NP_OIDC_POST_LOGOUT_URI=https://np.lihato.icu/`.
+- Redis stores the live queue and login sessions. SQLite WAL at `/data/np-replica.sqlite3` stores users, owned jobs, compressed inputs/results/errors, usage totals, and durable share links.
