- Connect aMoveToCommandZone to cmMoveToCommandZone; the menu item was
added, shown, and shortcut-bound but never wired, so it did nothing
- Extract evaluateModifyCounter() and route cmdIncCounter/cmdSetCounter
through it, replacing isCommandZoneCounterBlocked; reject inc/set on
an inactive tax counter so a hidden counter cannot accumulate value
- Reject reserved tax counter names in cmdCreateCounter to prevent a
client from spoofing a system tax counter via a user-created counter
- Route AbstractCounter::valueChanged through the virtual setValue() so
CommanderTaxCounter clamps and refreshes its tooltip on value changes
- Deduplicate actPlayAndIncreaseTax/actPlayAndIncreasePartnerTax into a
single playAndIncreaseTax(counterId) helper
- Move MINIMUM_STACKING_HEIGHT from CommandZone to the PlayerGraphicsItem
layout code, its only consumer
- Remove unused AbstractCounter forward declaration from player_logic.h
- Add EvaluateModifyCounter tests and PartnerTax cases for
evaluateSetCounterActive
- Pin the FirstUserId floor in new_counter_id_test using ids 3 and 5 so
a naive "highest id + 1" regression fails the test
Pull the pure guard logic out of cmdDelCounter and cmdSetCounterActive
into static evaluateDelCounter/evaluateSetCounterActive methods, leaving
the handlers as thin shells over the decision. Add command_zone_tests
covering every authorization branch of both evaluators.
