SITE USCDI v3 E1 Ambulatory Sample2 reference provenance clarification

[Daniel Xu]

Please provide the exact reference C-CDA, version and SHA-256 used by SITE Sender / 170.315_e1_VDT_Amb / 170.315_e1_vdt_amb_svap_uscdiv3_sample2_v1.pdf. Please identify the authoritative sources for the H&P clinical effective time, original author time 201507221100-0500 (including timezone basis), and represented organization. How do these differ from the document-level 20150722 and Neighborhood Physicians Practice expectations? The supplied PDF identifies document-level authorship and custodian information but does not establish that note-specific tuple. How should a newly generated summary represent these historical facts separately from current recording and signing, while preserving unknown provenance in immutable earlier notes?
