# The worked example A finished 24-event session showing what a C-K tree looks like when it fixates and when it stops fixating. Use it to explain the method to someone who has never met it, or to remind yourself what a good tree looks like before starting a real one. ## Load it The example ships inside the plugin and is never written into a project unless asked. Copy it into the user's project so they can branch from it and keep their edits: ```bash mkdir -p sessions cp "${CLAUDE_PLUGIN_ROOT}/sessions/example-hull-speed.ck.json" sessions/ ck view --open ck render sessions/example-hull-speed.ck.json --label example ``` If `sessions/example-hull-speed.ck.json` already exists, do **not** overwrite it — the user may have branched from it. Say so and open what is there. Give them the **full URL including `?key=…`**; the server 403s without it. ## Walk them through it The point of the example is a single contrast, and it is lost if you narrate all 24 events. Drive the timeline scrubber and stop twice. **Stop at event 7.** The tree is at 0% expansive with both branches dead. Say what that is: not a failure of effort but an accurate picture of what a century of naval architecture actually did. Displacement hulls have a speed wall set by the wave they make; every partition in the tree so far accepts the hull and attacks the wave. The metrics panel is showing fixation, and nothing in the concept space can escape it, because the escape is not in the concept space. Then point a
