architecture

# Architecture assessment and authoring ## Workflow role - role_name: architecture - stage: authoring - upstream: approved spec and current spec review - downstream: architecture-review - summary: Assess architecture impact and author the smallest justified package. - ownership: Architecture artifacts and authorized architecture authoring evidence only. - must_not_claim: architecture-review approval, plan readiness, implementation readiness, verification, branch readiness, release readiness, or PR readiness. Portable work is isolated. Workflow-managed execution does not enlarge the architecture write set. ## Evidence and upstream settlement Read current guidance, proposal, approved spec/review, canonical architecture, relevant ADRs, project map, and affected system surfaces. Rank governing artifacts above history and inference; upstream artifacts and state are read-only. Require an approved current spec without later contradiction or open resolution. Route unsettled direction to `proposal`, unclear behavior to `spec`, and missing settlement to `spec-review`. ## Classification and loaded assemblies Classify before mutation. Assessment mode is `isolated` or `workflow-managed`; applicability judgment is `required`, `not-required`, or `ambiguous`; route result is `architecture-required`, `architecture-not-required`, or `architecture-ambiguous`; authoring action is `assessment-only`, `canonical-update`, `adr-only`, `canonical-update-with-adr`, or `blocked`. | Assembly | U...
