CB.2:11 - SoTA-Echoing

Source line or developed treatment	Adopted or adapted contribution	Boundary and effect on the method
David Spinks, The Business of Belonging (2021), physical PDF pp.68–76 and 108–111	Start with a manageable scope, recruit deliberately and supply early organising work where spontaneous exchange is absent.	The life-cycle stages, activity percentages and growth stories are historical heuristics and cases, not universal thresholds. The method chooses support from the actual exchange.
Spinks, physical PDF pp.77–100	Make the intended participation recognisable and inspect who is missing from the first group.	Identity and belonging can matter without making increasing activity every person’s required trajectory.
OCE.2’s treatment of actual work, supplied results and constraints	Identify the work that makes an exchange possible and retain uncertainty about unavailable contributions.	CB adapts this to independent participants and voluntary contribution; it does not infer positions or authority from participation.
HCD.5/6’s treatment of helped performance and later observation	Keep receiving help, performing an action and developing capability distinguishable.	Use learning methods when learning is the purpose. A community interaction alone supplies no learning verdict.

Source return: David Spinks, The Business of Belonging (2021). The construction retains the useful manual-start proposal while replacing generic activity targets with the participants’ result, acceptable burden and actual support conditions. Prefer an adequate resource, professional service or independent-learning route when it supplies the receiving use more directly.
