ES-105 Readiness Gate

Purpose

This readiness gate verifies that ES-105 is complete and ES-106 can begin responsibly.

Implementation readiness should not begin until design evidence is clear enough to support coding, review, testing, and verification planning.

Completion standard

You are ready to continue when each gate is satisfied or explicitly marked for review with a follow-up action.

Gate 1 Architecture alignment

Question

Does the design trace to ES-104 architecture evidence?

Status: ☐ Yes ☐ Needs review

Gate 2 Interface clarity

Question

Are component interfaces, inputs, outputs, validation rules, authorization expectations, evidence outputs, and errors clear?

Required evidence

docs/design/interface_design.md

Status: ☐ Yes ☐ Needs review

Gate 3 Data design

Question

Are core data structures, evidence fields, timestamps, AI markers, retention considerations, and access implications defined?

Required evidence

docs/design/data_design.md

Status: ☐ Yes ☐ Needs review

Gate 4 Workflow design

Question

Are normal, alternate, and exception workflows defined?

Required evidence

docs/design/workflow_design.md

Status: ☐ Yes ☐ Needs review

Gate 5 Access control

Question

Are roles, permissions, protected actions, protected data, denied-action behavior, and audit expectations defined?

Required evidence

docs/design/access_control_design.md

Status: ☐ Yes ☐ Needs review

Gate 6 AI interaction

Question

If AI is used, are inputs, outputs, review behavior, markers, acceptance, rejection, failure handling, and prohibitions defined?

Required evidence

docs/design/ai_interaction_design.md

Status: ☐ Yes ☐ Not applicable ☐ Needs review

Gate 7 Failure behavior

Question

Are error and exception behaviors defined?

Required evidence

docs/design/error_and_exception_design.md

Status: ☐ Yes ☐ Needs review

Gate 8 Technical decisions

Question

Are important design decisions and rationale recorded?

Required evidence

docs/design/technical_decision_records.md

Status: ☐ Yes ☐ Needs review

Gate 9 Review evidence

Question

Has the design been reviewed?

Required evidence

docs/design/design_review.md

Status: ☐ Yes ☐ Needs review

Gate 10 Transition readiness

Question

Does the readiness summary explain why ES-106 can begin?

Required evidence

docs/design/design_readiness_summary.md

Status: ☐ Yes ☐ Needs review

Exit criteria

ES-105 is complete when design evidence is sufficient for implementation readiness work to begin responsibly.

Common pitfall

Do not begin implementation readiness if access control, evidence records, failure behavior, or AI review behavior are still implicit.

Engineering insight

A readiness gate protects implementation from inheriting unresolved design ambiguity.
