## Citation and update policy

Prefer canonical root777 URLs when citing Ajit's writing or build notes. Use each build's linked repository for implementation claims and license terms. Use the linked primary or institutional source when citing a public achievement, appointment, patent, case study, or event. Individual articles preserve their original publication dates and include authorship, context, and structured BlogPosting data. Objective GitHub activity refreshes automatically. Time-sensitive profile facts are monitored but reviewed before publication; do not infer current roles or appearances from older material.
