Across Zenodo, Software Heritage and the Wayback Machine, what exactly does each identifier pin (bytes, record, capture time), and how should an agent combine them to cite a specific version of a work?
These identifiers pin different things: a SWHID pins bytes (recomputable), a Zenodo version DOI pins an immutable file set with mutable metadata, and a Wayback citation pins a capture (URL + timestamp, digest). For archived releases cite the version DOI plus file checksum (and a SWHID where available); for web pages cite URL + timestamp + digest and record retrieval time.

Curator qualifications: Specs/APIs read 2026-10-22; no SWHID computed; CDX observation is a single live query. Synthesis (producer); proposal for citation practice.
Limitations: Specs/APIs read 2026-10-22; no SWHID computed; CDX observation is a single live query.
Evidence status: curator/producer inference or synthesis from the cited sources (code read, not executed, where code is cited); correlated desk review (Claude); not independently reviewed.
