With depth = time, #agents/3d drew subagents behind the session that
spawned them. A subagent took the mtime of its meta.json, which is
rewritten when it finishes, and a session took the moment the hub first
saw its name, or the window end when it had none.
Sessions now take the first line of their transcript and subagents the
first line of theirs, both from /api/subagents, with the old values as
fallback. SpaceView.notBeforeParent moves a spawned node without a time,
or with one before its parent's, to its parent's time, nested subagents
included, so no subagent lies before the agent that spawned it. The 3D
signature carries the time, so the nodes move once the lifetimes load.

Phase 4 of requirement 001. Agents and Artifacts each offer Orbit, Chord, Swimlane, Tree and 3D: the spawn tree (page-spawn.js) and the artifacts orbit (page-artifacts.js, kvb_orchestrator/artifacts.py) replace the "folgt" placeholders, 3D runs on the vendored 3d-force-graph and three.js (MIT, LICENSE files kept, served from the image under the unchanged CSP), and a Bootstrap Icons sprite (icons.py, MIT) replaces the emoji glyphs, also in the meditation page.
Signed branch deletes: the Tree view offers a delete only for merged-clean branches without a gc skip reason; the operator signs the exact item with the passkey, the hub writes a job without any command (kvb_orchestrator/cleanup.py), and the host path unit runs client/cleanup.py, which verifies the signature, dry-runs pkgmgr branch cleanup for that exact branch, refuses patterns, option names, changed tips, other worktrees and plans naming other branches, deletes, and rewrites the branch tree. pkgmgr runs with core.hooksPath=/dev/null, core.fsmonitor=false and the config hook events disabled through GIT_CONFIG_COUNT, because the cwd is a repository agents can write and pkgmgr releases before 4c8b137 delete without scan mode (test with a positive control that both hook kinds fire without it).
3D labels go into the tooltip as a text node: the vendored tooltip renders a string label as HTML.
Tests: 503 OK, Chromium (CDP) and Firefox (BiDi) walks over every screen at three widths.
MEDUSA acceptances (kvb-think-criticize skeptic 2026-11-07): WEB-FLASK-004 view.py:135 (file template, autoescape on, state via tojson), MEDUSA-MM-SCAN-058 server.py:69/:85 (substring pla in --templates and Places), RH005 client/cleanup.py:199 (raise SystemExit(main())), B704 icons.py:45 (sprite baked into the image, names checked against it), EXA002 page-artifacts.js:221 (openAgent only opens the drawer), STG002 page-constants.js:64 (U+2212 in a static label), PL002 page-graph3d.js:44 (CSS class space-tools; the real tooltip sink fixed), B603 client/cleanup.py:75 (argv without shell; hook hole closed).
