1.1 The shift from 'essential documents' to 'essential records': what E6(R3) Appendix C changed and why it matters
Traces the terminological and conceptual shift from 'essential documents' in E6(R2) to 'essential records' in E6(R3) Appendix C and its infrastructure implications.

1.2 The essentiality determination: applying the framework to decide what must be retained
Teaches the RC to apply ICH E6(R3) Appendix C, Section C.3 criteria as the analytical framework governing what the site's records infrastructure must accommodate.

1.3 Timing and responsibility: which records are needed at which trial phases, and who generates them
Establishes the temporal dimension of essential record generation across trial phases for the RC managing records infrastructure across studies simultaneously in different lifecycle phases.

1.4 The investigator's record-keeping obligations under ICH E6(R3) Annex 1, Section 2.12: and how the RC ensures they are met
Maps every Section 2.12 requirement to the operational infrastructure the RC must provide, clarifying the distinction between the investigator's nondelegable regulatory responsibility and the RC's operational supporting role.
