Record the score's delta chip in the affordance ledger

The panel picked up a green +N chip beside its label when the score moved
back into the band, and the repo-wide affordance guard counts that colour
wherever it appears outside the outcome module. The chip reports a week that
went up rather than an action that succeeded, so it is recorded here at
exactly one use rather than routed through the outcome table.
