Archetype_App_Triage

Step 3 of the Archetype Builder pipeline. For each external data dependency captured in Discovery, decide reuse_existing (existing app fits cleanly) | patch_in_place (existing app close but needs small extension; default no version bump per AMAZON v2.0.0 precedent) | new_build (no candidate, hand off to App Architect playbook for execution) | none_needed (deterministic logic / inline string handling, e.g., the cart URL concat pattern). Triage is the decision gate; App Architect is the new-build executor — load it via SKILL_LoadPlaybook on new_build paths. Audits candidate apps via APP_Catalog + APP_Get(scope='full'). Captures patch notes and rationale per decision. Captures any required API keys via TENET_Update bucket='apiKey'. Output: brief.appTriage.decisions populated 1:1 with discovery.externalDataDependencies; appTriage.completedUtc set.
