C.32.ADA:11 - SoTA-Echoing

These sources inform the coordinates, value meanings, stop conditions, and repair exits used below.

Current FPF E.21 scale disciplineExisting FPF pattern for declared-use evaluation, exact 0 absent through 5 exceptionallyExpressedForDeclaredUse labels, complete coordinates, adjacent-value rationale, and no averaging.Reuse the value domain and evaluation discipline for architecture decisions without copying pattern-quality coordinates.ADA requires declared use, complete coordinate set, E.21 value labels with adjacent rationale, no average, and use-specific stop conditions.E.21 pattern-quality status and coordinates are not architecture-decision adequacy.
C.32.PAD and C.32.ADRPAD and ADR define the decision relation and publication projection being evaluated.Make relation adequacy and projection adequacy separate coordinates.ADA can say a PAD relation is usable while ADR projection needs repair, or the reverse.A complete ADR does not make the decision relation adequate.
ISO/IEC/IEEE 42010:2022 official standard (https://www.iso.org/standard/74393.html; IEEE page https://standards.ieee.org/ieee/42010/6846/) with the 42010 companion site as secondary reading (https://iso-architecture.org/42010/)Current official source for architecture descriptions, viewpoints, views, correspondence, and rationale; the companion site is used only as secondary reading.Add coordinates for affected structure, architecture-description adequacy, and source-return.ADA identifies C.30.AD and C.30.ASV as subject-pattern locators for weak description assertions.Architecture-description adequacy does not decide or approve the architecture.
Ford, Parsons, Kua, and Sadalage, Building Evolutionary Architectures, 2nd ed. (https://www.oreilly.com/library/view/building-evolutionary-architectures/9781492097532/)Current practitioner source for architecture feedback and incremental change under eval-like mechanisms.Add evolution, reopen, guardrail, and confirmation coordinates.ADA checks reopen and eval exits before a decision is used for long-running work.Source-side fitness-function wording is not imported as ADA object naming.
Ford, Richards, Sadalage, and Dehghani, Software Architecture: The Hard Parts (https://www.oreilly.com/library/view/software-architecture-the/9781492086888/)Current practitioner source for trade-off analysis under competing characteristics.Add architecture-characteristic trade-off adequacy and accepted-loss repair.ADA identifies ACS, ACE, C.16, C.25, C.31, or C.31.ASAP as subject-pattern locators for the exact weak trade-off assertion.Trade-off discussion is not an assurance claim or governance approval.
2026 ADR violation-detection research (https://arxiv.org/abs/2602.07609)LLM detection in the study was more accurate for explicit decisions checkable from code than for decisions left implicit or requiring deployment settings or organizational context.Add confirmation, source-return, method, deployment, and organization refs to adequacy checks when live.ADA scores confirmation and method docking separately and blocks hidden organizational knowledge from passing as ready.Automated violation detection is not proof, evidence, assurance, or gate passage.

Source-currentness boundary. Recheck a source row when FPF evaluation discipline, architecture-decision practice, ADR violation checking, evolutionary-architecture eval practice, or project governance changes a coordinate, value meaning, or repair exit.
