📋 Decision Context

Question:

What caused the remaining 5 test failures after the other agent's fix pass?

Task: S234.3: Fix remaining test failures

🎯 Decision Made

Chosen:

Two root causes: (1) sub-vitto-integration.spec.ts assumed orchestrationPlugin was the last plugin via plugins[plugins.length-1], but oauthPlugin was added after it in S234.3. Fixed by searching all plugins for the deploy_agents handler. (2) phase-executor.spec.ts CostTrackerService mock returned undefined from recordSpending(), but production code reads spendingRecord.costUsd. Fixed by returning { costUsd: 0 }.

Options Considered:

• No alternatives documented

💭 Reasoning

Both are mock maintenance issues: (1) The integration test was brittle — it relied on array position rather than content matching. This broke when we added a new plugin. The fix makes it robust against future plugin additions. (2) The CostTrackerService mock was incomplete — added in S231.2 when costUsd tracking was introduced, but the mock wasn't updated to return the expected shape. Both are instances of the convention we added earlier: when adding dependencies, always update all test mocks.
