Use these drills after completing all topics in Hierarchy & Budget Contracts. Answer with baseline, boundary, owner, metric, artifact, and regression scope.
[INT][SOC][HIERARCHY-BUDGETS]
Q: When does a block budget become invalid?
A:
When assumptions in timing, power, area, latency, or usage mode change without contract revision and owner signoff.
FOLLOW-UP TRAP: Keeping old targets and hoping downstream optimizations absorb the drift.[INT][SOC][HIERARCHY-BUDGETS]
Q: What is the fastest way to reduce unowned integration risk?
A:
Publish an owner-mapped risk matrix with SLA and escalation paths tied to milestone gates.
FOLLOW-UP TRAP: Tracking risk count without accountability.[INT][SOC][HIERARCHY-BUDGETS]
Q: Why do abstraction boundaries matter for closure speed?
A:
Because stable boundaries let teams debug with consistent assumptions instead of re-litigating hidden implementation details.
FOLLOW-UP TRAP: Sharing too much internal detail as a substitute for contracts.BASELINE -> OWNER -> CONTRACT -> METRIC -> FIX -> REGRESSIONHIERARCHY CONTRACT FLOW
