C.32.HCS:11 - SoTA-Echoing

These sources inform the starter-pack fields, ACS criteria-use conditions, and blocked overreads described below.

ISO/IEC 25010:2023 (https://www.iso.org/standard/78176.html) and SQuaRE quality-model practiceCurrent standard source for ICT product quality vocabulary; useful as a stable catalogue reference, not as FPF ontology.Use quality-model terms as source catalogue wording that must be rebound to the admitted holon family or recovered architecture-bearing family.Starter-pack rows separate starter heads, likely bearers or selected structures, any source-label recovery actually needed, and likely C.25 boundaries.An ICT product quality-model characteristic is not automatically a project criterion, holon ontology, scale row, eval program, or admission of a source label as a holon kind.
Richards and Ford, Fundamentals of Software Architecture, 2nd ed. (https://www.oreilly.com/library/view/fundamentals-of-software/9781098175504/)Current practitioner source for architectural characteristics, trade-offs, scope, and limiting the working set before measurement or governance.Keep the recurring-head idea, but generalize it only by rebinding family, bearer, and scale.HCS requires the architecture-bearing family, likely bearers, likely selected structures, a recovery-pattern ref only when needed, and first project questions before ACS criteria-row construction.Software architecture characteristic groupings cannot be copied into methods, roles, cultures, practices, built assets, or evidence workflows named by source wording without recovery and rebinding.
Ford, Parsons, Kua, and Sadalage, Building Evolutionary Architectures, 2nd ed. (https://www.oreilly.com/library/view/building-evolutionary-architectures/9781492097532/); Ciceri et al., Software Architecture Metrics (https://www.oreilly.com/library/view/software-architecture-metrics/9781098112226/)Current practitioner line for guided change, architecture characteristics, and metric or eval work after quality goals are named.Put HCS before metrics and eval programs: it supplies starter heads, then ACS chooses project rows and ACE defines eval programs when needed.HCS stop condition explicitly ends at starter heads, likely bearers, likely Q-Bundle boundaries, and first project questions for ACS.A metric, dashboard, imported fitness-function name, or imported eval-program name is not a starter pack, project criterion, architecture-characteristic eval program, or architecture decision.
Current FPF C.25, C.30, C.32.ACS, C.32.ACE, and C.16Local rules for Q-Bundles, grounded architecture, project criteria rows, eval programs, and measurement.Use HCS only for starter packs; use the named pattern for each stronger claim.HCS relations and conformance rows name C.25 for composite quality families, C.30 for selected-structure recovery, ACS for criteria rows, ACE for eval programs, and C.16 for measurement.A starter head is not a Q-Bundle, selected structure, measurement method, eval result, comparison rule, declared selected-set result, published selected set, local choice, or project architecture decision.

The bearer/domain distinction in §4.1 also uses C.30.ASV:4.5a and the developed instructional-design example in van Merriënboer, 4C/ID: An Overview of Main Design Principles (2019; author-hosted copy uploaded in 2021), its explanation of whole tasks, support and feedback. This is retained design lineage: it shows why a Method’s parts and their relations can matter to a learner result. HCS adopts that question, not a claim of instructional effectiveness for an untested population. Reopen the transfer when the target Method needs a relation or outcome the recovered structure does not represent.

Source-currentness boundary. Use ISO/IEC 25010:2023 as ICT product-quality vocabulary, not as holon-family ontology. Use the O’Reilly architecture-characteristic and evolutionary-architecture sources for recurring starter heads and for later metric or eval work after the heads are named. Use an FPF row only for the claim it defines, constrains, or tests. Reopen HCS when a named source edition changes starter-head guidance, when the pattern for a next question changes how it handles that source family, when repeated C.32.ACS uses show that a starter head never survives project binding, when repeated project uses reveal a missing head for the admitted holon family or recovered architecture-bearing family, or when source-label recovery changes the recovered family or bearer.
