`world_delta_of` wrote `delta` and `applied` only. Every consumer that tells a
refused change from a successful one reads the two lists it dropped:
`Action.world_changes` marks a clamped chip from `clamped` and builds its
refusal chips from `rejected`, and `worldstate.refusals` reads both. So no chip
could report a limit, no rejection chip could appear, and no correction ever
reached the next prompt. The three mechanisms merged last session were live in
the code and unreachable in production.
Found by playing the Pokemon demo. Turn 3's snapshot held two clamped entries
with correct `fix` text, both chips came back `clamped: false`, and turn 4's
prompt carried no correction, so the model repeated the same mistake.
The 21 tests passed because `action()` built the column by hand with every list
present. It now fills the column through `world_delta_of`. Removing the two new
lines fails 9 of the 23 tests; that was checked by sabotage.
