HISTORICAL PATTERN MIGRATION RECORD

Use this record when a roadmap, design review, vendor deck, or legacy repository uses an older agent pattern name.
The goal is to translate the label into a current, testable architecture decision.

1. Source
Legacy term:
Source or link:
Who is using the term:
Date reviewed:
Reviewer:

2. Claimed capability
What the term claims the system can do:
What user or business problem it is meant to solve:
What evidence the source provides:

3. Translation
Current decision category:
[ ] Pattern selection
[ ] Runtime foundation
[ ] Control loop
[ ] Context, memory, or knowledge
[ ] Tools, skills, or protocols
[ ] Multi-agent topology
[ ] System architecture
[ ] Production runtime
[ ] Product workflow
[ ] Other:

Hidden decision:
What must the team actually decide?

Ownership boundary:
Who owns state:
Who owns tools:
Who owns policy:
Who owns memory:
Who owns final acceptance:
Who owns rollback:

4. Current chapter mapping
Primary replacement chapter:
Secondary replacement chapters:
Why this mapping is stronger than the legacy label:

5. Evidence required
Required artifact:
[ ] System boundary diagram
[ ] Typed contract or schema
[ ] Tool manifest
[ ] Approval record
[ ] Eval fixture
[ ] Trace or transcript
[ ] Runbook
[ ] Rollback command
[ ] Cost or latency budget
[ ] Security review

Evidence link or location:

6. Risk review
What could go wrong if the legacy label drives the architecture:
What current chapter reduces that risk:
What decision remains unresolved:

7. Triage score
Score each category 0, 1, or 2.

Intent:
Boundary:
Implementation:
Failure modes:
Evaluation:
Operations:
Total:

Score interpretation:
[ ] 0-4: keep deprecated
[ ] 5-8: map to existing chapter
[ ] 9-12: candidate new chapter after code and eval evidence exists

8. Promotion decision
Decision:
[ ] Keep deprecated
[ ] Map to existing chapter
[ ] Candidate new chapter

Reason:

New chapter is allowed only if the term has a distinct intent, implementation shape, failure mode, eval method, and production guidance.
