+## Summary
+
+_<!-- Insert Title Here -->_
+
+### Driving User Story
+
+**As a [primary actor],**
+**I want [an action or feature],**
+**With [additional requirement or side-effect],**
+**So that [a reason or benefit].**
+
+## Context
+
+- [  ] I have looked for similar use cases and feel this issue is a distinct use-case, rather than best encoded as a variant or "alternate path" to an existing one.
+
+### Related Use Cases  
+
+<--! Leave empty if none; otherwise, a bullet list is best, whether annotated or not. -->
+
+### Terminology
+
+<!-- If you use any terms differently or more precisely than usual -->
+
+### Actors
+
+<!-- Enumerate every actor, server, service, process that will take an action or reaction, including storage, forwarding, etc. 
+Optionally, mark one actor as primary. -->
+
+### Other Stakeholders
+
+<!-- e.g. auditors, regulators, forensic accountants, martian anthropologists, etc. -->
+
+## Flows
+
+<!-- Feel free to write "TBD" or "N/A" for any subsections you don't have a clear answer for year, but don't remove them, it's a helpful reminder for later. -->
+
+### 0 - Preconditions
+
+<!-- What conditions must be in place or assumed before this use case can begin? -->
+
+### 1 - Trigger
+
+<!-- What (user or system) event or action initiates this use case? -->
+
+### 2A - Happy Path
+
+### 2B - Alternative Paths
+
+<!-- Feel free to not just list these at a high level, but name these and add a #### heading for each, now or later -->
+
+### 3A - Challenges and Key Risks
+
+<!-- Can be failure modes/conditions or just more qualitative issues that affect satisfaction/safety less definitively. 
+Feel free to not just list these at a high level, but name these and add a #### heading for each, now or later -->
+
+### 3B - Success Criteria
+
+<!-- What conditions or criteria must be met for this use case to be considered successfully handled? What limitations are acceptable? 
+To put it another way, what observable behaviors or metrics can be used to detect a failure more, or differentiate happy paths-or-outcomes from less-happy paths-or-outcomes? -->
+
+### 3C - Acceptable Outcomes
+
+<!-- Distinct from whether or not a flow was succesful or which outcome, what are the minimally required outcomes or side-effects (e.g. logs) across all outcomes. -->
+
+## References
+
+### Prior Art
+
+<!-- Highly recommend including links to blog posts, case studies, thought experiments, and prototypes that influenced this idea, including your own! good to have a [timestamped] snapshot if you want bragging rights about your input to the collective process 😉 -->
