`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.

`apply_delta` records three outcomes for every change the model sends:
`applied`, `clamped`, and `rejected`. Everything downstream read only
`applied`. A refused change reached the player as an ordinary chip, and
reached the model on the next turn as a change that had succeeded.
Five parts:
- `Action.world_changes` reads `clamped` and `rejected` beside `applied`.
Accepted stats carry a `clamped` flag; refusals become `kind: "rejected"`
entries. The `fix` key is present only when the engine wrote one, because
this property runs for every action of every list response.
- The UI separates the three outcomes. A clamp to a standstill reads
`no change - at its limit` on a dashed chip, a partial clamp is marked
`(limited)`, and a rejection carries its reason. Dashed and dimmed rather
than red: a refused change means the rules are working.
- The goals line names the milestone id, as `milestones.<id>`. The ids
appeared nowhere in the prompt before, so the model could not send one.
- Each rejection, and each clamp that moved nothing, builds a `fix` string
from the stat definition at the point of refusal. `render_refusals()`
renders them into the next prompt above `EMIT_REMINDER`.
- `_history_text` replays `applied_delta()` instead of the sent delta, so a
past turn's state block shows only what the engine accepted.
A clamp that reduced a change but still moved the value reports nothing. If
you tell a model its 80 damage became 30, it can treat the shortfall as a
debt and send the remaining 50 next turn, which is the swing
`max_delta_per_turn` prevents.
In the demo scenario, `pokemon_left` becomes `pokemon_fainted`
(`type: counter`, `initial: 0`). Starting at the ceiling turned a wrong-signed
delta into a silent no-op; counting up puts the wrong sign on the counter
rule, which refuses it out loud. The instructions also now ask for
`world.turn`, which sat at 0 for a whole playtest.
