Add ContractCompletionOperations orchestrator (deliver-then-mark,
outcome audit), hook from EncounterCompletionOperations after E5.M3
loot and quest wiring, extend dev fixture reset for contract rows,
Bruno quest-fixture reset request, and cover with tests (904 green).
Extend quest and resource-node fixture APIs so Bruno pre-requests can reset shared dev-local-1 state (cooldowns, nodes, inventory, quest progress) instead of relying on a fresh Postgres baseline.
Add POST …/__dev/quest-fixture to mark quests completed without reward
delivery; wire Bruno pre-request and CI flag. Multi-rule AND unit test,
README notes, gate deny comment, review strikethroughs.
