be-agent-ready `structured-agent-capabilities`	not-applicable	high	The site exposes public community content but no agent-facing transactional surface, and robots.txt explicitly opts most bulk AI crawlers out while allowing user/search agents; this emerging capability is not assumed.
be-agent-ready `on-device-inference`	not-applicable	high	The site exposes public community content but no agent-facing transactional surface, and robots.txt explicitly opts most bulk AI crawlers out while allowing user/search agents; this emerging capability is not assumed.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	high	After ten full-page scroll down/up cycles, retained heap was 23.78MB versus a 22.24MB clean baseline (+6.9%) and node count +7.4%; growth was bounded and consistent with first-time lazy/ad work, not evidence of unbounded accumulation.
be-memory-efficient `bounded-footprint`	pass	high	The clean loaded homepage retained 22.24MB across 384,114 heap nodes, proportionate to this script- and ad-heavy community page despite optimization opportunities.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	Neither heap summary surfaced Detached* constructors among the dominant populations, and repeated scrolling produced no runaway constructor growth; confidence is medium because listener instrumentation was not available.
