Deck-mount fasteners penetrate the membrane and rely on exposed sealant joints prone to failure, while face-mount avoids membrane penetration but demands robust structural backing and may not be feasible on all building geometries.","tags":["railings","waterproofing","deck-mount","face-mount","balconies","construction","membrane-protection"],"key_entities":[{"name":"deck-mount railings","type":"concept","confidence":0.95},{"name":"face-mount railings","type":"concept","confidence":0.95},{"name":"waterproofing membrane","type":"concept","confidence":0.92},{"name":"drip-through balconies","type":"concept","confidence":0.88},{"name":"elevated concrete balconies","type":"concept","confidence":0.85},{"name":"composite decking","type":"technology","confidence":0.8}],"classification":"reference","language":"en","confidence":0.85,"provenance":{"model":"claude-haiku-4-5","tool":"@stacklist/be@0.1.0","confidence":0.85,"timestamp":"2026-10-21T20:08:05.650Z"},"token_counts":{"approximate":2022,"cl100k":1618},"content_hash":"sha256:4aa9b170aed60ffbf779f65ee6ce3bb532e7b991ac3df395d34ce6bd32e5dc03","acp_version":"0.2","body_available":true,"body_tokens":2022,"visibility":"public","agent_accessible":true,"status":"final"},"_links":{"self":"/api/public/card/729c4c77-fe70-431c-a70d-ff74263382ec.json","html":"https://stacklist.com/card/729c4c77-fe70-431c-a70d-ff74263382ec","md":"/api/public/card/729c4c77-fe70-431c-a70d-ff74263382ec.md","stack_json":"/api/public/stack/d2ee3c27-eae3-4a1e-aee2-633850a041f1.json"}}
