Cross-language versioning becomes unstable when time is present in the source but absent from the reconstructed answer.
What the phenomenon looks like
The FR and EN versions may be semantically aligned at one moment, then age at different speeds. One language receives the update, the clarification, or the correction first, and synthesis begins averaging across two temporal states.
Why it happens
Generative systems do not inherently privilege the newest version. They privilege salience, repetition, document stability, and the persistence of older signals across the web.
Why it matters
The result is a hybrid public answer: not fully obsolete, not fully current, but reconstructed from the lag between languages. That lag becomes an interpretive vulnerability rather than a simple editorial delay.
What must be governed
- Version multilingual canonical pages as one governance surface, not as independent editorial streams.
- Flag cross-language divergence when it concerns perimeter, authority, or exclusions.
- Prioritize temporal synchronization on high-governance assertions before translating secondary nuance.
