discarding it. Preserve the existing None validation and ensure the stored

rejecting negative values while preserving their existing defaults and

The 2026-07-28 extraction targeted a standalone Eval Author plugin. That goal is retired: the customer-facing path is a skill rather than a plugin install, and Experimentalist insight mode is the agent's only caller. The agent sits next to the evaluator, staging, trace, and reporting helpers it borrowed, which removes the package cycle that uv had to resolve and turns ten rows of tracked debt into ordinary intra-package imports. The ratchet in test_plugin_boundary.py drops from ten borrowed modules to one: the platform client that discovery/ builds on. The eval-author plugin keeps the `nemo agents eval-author` command group and its discovery/ package. The move adds no dependencies, because Experimentalist already declares harbor, nooa, pydantic, tomlkit, nemo-insights-plugin, and nemo-platform-plugin. It drops nooa and tomlkit from the eval-author plugin, which only the agent used. Signed-off-by: Alec Khoury <akhoury@nvidia.com>
The plugin README listed Eval Author under "Where it fits" as an external component, linking to the Eval Author plugin README that documents only the `nemo agents eval-author` commands. The agent ships inside this plugin, so the link goes to its package README instead. Signed-off-by: Alec Khoury <akhoury@nvidia.com>
The ratchet tracked ten Experimentalist modules that Eval Author borrowed, and its rule was to duplicate each helper until the list reached zero. Moving the agent into Experimentalist turned nine of those borrows into intra-package imports, and the tenth, make_client, sits in discovery/, which is planned for removal once the skill lands. A one-entry ratchet enforcing a retired standalone goal misdirects more than it protects. The invariant worth keeping is the reverse one: Experimentalist must not depend on the Eval Author plugin, because that restores the package cycle. The existing test_contract_dependency.py already asserts which dependencies must and must not be present, so the check goes there as a single assertion. Re-adding the dependency makes it fail. Also trims the plugin README instead of relocating the discover CLI reference into it, because that command is going away. Signed-off-by: Alec Khoury <akhoury@nvidia.com>

The SDK wrapper's extras are generated from each plugin's dependency list, so dropping nooa and tomlkit from the Eval Author plugin, and the Eval Author plugin from Experimentalist, left packages/nemo_platform/pyproject.toml stale and failed lint-sdk-vendored. Regenerated with make vendor. Three deletions, all mechanical. The moved agent still imports nooa and tomlkit, and Experimentalist already declared both.

The vendor commit changed packages/nemo_platform/pyproject.toml without the lockfile, so Check uv lock failed. Regenerated with script/uv-lock.sh, the sanctioned updater, which pins uv 0.9.14 to match CI and platform containers. The twelve deletions are the intended ones: nemo-eval-author-plugin leaves Experimentalist and the all, plugins, and services extras, and nooa and tomlkit leave the Eval Author extra. No package version or source changed. The 361 insertions are all wheel URLs, an inventory refresh that any lock regeneration picks up today and that carries no resolution change.

Summary
The 2026-07-28 extraction moved the Eval Author agent into its own plugin, targeting a standalone Eval Author. That goal is retired: the customer-facing path is a skill rather than a plugin install, and Experimentalist insight mode is the agent's only caller. This moves the agent back into the Experimentalist plugin, which removes the package cycle that
uvhad to resolve and collapses most of the tracked dependency debt into ordinary intra-package imports.Behavior does not change.
