Check for alignment with the spirit and specifics of Teresa Torres perspective on OSTs

[mindsocket]

The schema bakes in a bunch of principles that I've not yet checked against "official" guidance on OSTs.

That might be ok, but it would help to work out the differences, decide which ones need addressing or documenting, and even consider if there's a strict vs relaxed or other "modes" (alt schemas).

Research complete. Full findings documented in docs/torres-alignment-research.md (including a reflection section with design decisions arising from the research).

Summary of divergences from Torres' model

Topic	Torres	Current schema	Assessment
Root node	Single product metric ("desired outcome")	Vision → Mission → Goal hierarchy	Intentional extension — covers strategic context Torres considers out-of-scope
Bottom layer	Assumption tests	Not present	Gap — being addressed in #14 and #15
Opportunity rules	Customer-voiced, grounded in research, in problem space	Free-form, no enforcement	Hard to enforce structurally; descriptive rules (#16) and strict_ost schema (#15) address this
Numeric assessments	Not from Torres' model	impact/feasibility/resources on opportunity/solution	Reasonable pragmatic addition; excluded from strict_ost
Solution parentage	Opportunity only	Opportunity or Solution	Extension — sub-solutions not in Torres; excluded from strict_ost
Terminology	"assumption test" (not "experiment")	Neither present	Type aliases (#14) accept both
