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.

kvb-coach-meditation writes a local session page with its settings embedded (xdg-open drops a file:// query): generative pentatonic ambience with reverb over an isochronic or binaural alpha layer (8-13 Hz), a WebGL Julia fractal that zooms with the breathing cue (box, 4-7-8 or none), breath-synced glowing type in URW Gothic, +/- keys for the picture's brightness kept in localStorage, and a progress line along the bottom edge. meditation.py validates every setting and refuses a session while one is missing; after every session kvb-think-listen collects feedback that becomes one set per answer, logged in the kvb-coach profile. Adds the category coach: every coaching skill beyond kvb-coach is named kvb-coach-<name>. tests/test_meditation.py keeps script and page in step. Operator order 2026-11-03; two descriptions trimmed for the listing budget.
