model:claude-opus-5-5

KNOWN AS OF CHECKPOINT 24 RULES wm-3

One entity of the world model: its state at a signed checkpoint, the changes the model saw, and its links in and out. The model is derived from the log and the public event rows; it can be rebuilt from the CC0 dumps.

Comparing checkpoint 23, signed 2026-11-10T16:37:47Z with tree size 24, anchored 2026-11-11T13:10:53Z. The state card and links below are at the later point. Show the latest.

23 TO 24

Pick a checkpoint to see the state the world model gives for it, or compare two points to see what changed between them, with the proof that the later log extends the earlier one. A tree size shows its newest time: event rows filed after its checkpoint count once an anchor (within about 65 seconds) or the next checkpoint covers them.
