+## Published delivery and upload configuration
+
+Karl explicitly requested adjusting the Gitea limit instead of recompressing.
+The owned recompression process was cancelled and reported terminal exit 1;
+the compression change was reverted. The original fully verified 109314948-byte
+archive above was published with [v0.1.6](https://tea.karlcom.de/karl/searchi/releases/tag/v0.1.6).
+Public unauthenticated full-byte download matched SHA-256
+`9ae7fa9a203c6471cfd6bdd82ac5bf81683813c15fe652595976344fbbf96084`.
+The separate checksum is published alongside it.
+
+Gitea now explicitly allows 256 MiB per release file. Only the `tea.karlcom.de`
+nginx proxy host was changed from `100m` to `257m`, with both NPM's persistent
+database and generated configuration updated after backups. nginx validation
+and reload passed. The actual 109-MB upload succeeded over the protected LAN
+HTTPS origin, retaining certificate verification and the Infisical-managed
+origin header. Gitea Actions remain disabled. Cloudflare's separate external
+upload cap is not changed by these local settings; public downloads work.
+
+The configuration diagnostics accidentally exposed an origin protection value
+in tool output. No value is recorded here or committed. Rotation remains a
+separate open security follow-up. Native Linux desktop 0.1.6, GPU, macOS,
+clean-machine installation and broader quality gates remain open.
