Big Bang 80/20: Specification Closure

Core Concept

Specification closure is the gate before EPIC 9 fan-out.

No implementation begins without closure verification.

Closure Checklist

A specification is closed when:

  • All inputs characterized (domain, constraints, edge cases)
  • All outputs specified (behavior, invariants, success criteria)
  • All errors enumerated (what happens when things fail)
  • All ambiguities resolved (no TBD, TODO, undefined)
  • All user stories have acceptance scenarios
  • SHACL validation passes

Quick Validation

# Check for incomplete markers
grep -r "TBD\|TODO\|FIXME\|undefined" .specify/

# Validate SHACL conformance
cargo make speckit-validate
