From deeb5ecd8612aaccaba5bf5ae758dbfef3bcb71e Mon Sep 17 00:00:00 2001 From: iris Date: Sun, 1 Nov 2026 16:22:40 +0100 Subject: [PATCH] hive ui: remove the BUILD L0GS tab and the live build-log panel A build's output and history are the swarm's builds Grafana board now, from the lines hive-c0re logs. Removes the tab and its pane, the live log under the rebuild queue, their styles, the log stream helper and the duration formatter only they used, and the docs; also the tab-counts sentence 5925 missed. --- docs/web-ui/README.md | 5 +- docs/web-ui/dashboard.md | 53 +-- frontend/packages/dashboard/src/builds.js | 406 +----------------- frontend/packages/dashboard/src/common.js | 54 +-- frontend/packages/dashboard/src/dashboard.css | 117 ----- frontend/packages/dashboard/src/index.html | 39 -- .../dashboard/src/system-sections.css | 74 ---- frontend/packages/dashboard/src/tabs.js | 9 +- frontend/packages/dashboard/src/util.js | 13 - 9 files changed, 29 insertions(+), 741 deletions(-) diff --git a/docs/web-ui/README.md b/docs/web-ui/README.md index 033fa629..2483fdb4 100644 --- a/docs/web-ui/README.md +++ b/docs/web-ui/README.md @@ -20,9 +20,8 @@ page with four tabs: - **4G3NTS** — every agent, live.
