-# System One Code Locator — Archived Narness Snapshot
+# Code Locator research
 
-> Status: Archived in Narness. Active implementation and ongoing research have moved to [BestNathan/system-one-code-explore](https://github.com/BestNathan/system-one-code-explore).
+> Status: Migrated. Narness no longer contains the Code Locator implementation, fixtures, tests, experiment workflows, or run artifacts.
 
-This directory is retained as historical evidence for the early Code Locator experiment that was merged into Narness in [PR #16](https://github.com/BestNathan/narness-engineering/pull/16).
+Code Locator started in Narness as a case study for System One progressive action spaces. The implementation and ongoing research now live in:
 
-It is **not** the current Code Locator implementation and should not be used as the starting point for new experiments.
-
-## Why this snapshot remains
-
-Code Locator began as a concrete test of the System One Progressive Action Spaces thesis:
-
-~~~text
-large environment
-  -> bounded grounded frontier
-  -> fast model judgment
-  -> typed effect
-  -> observation
-  -> new state
-~~~
-
-The early prototype in this directory explored hierarchical repository localization and established the first reproducible fixtures, traces, and workflow evidence.
-
-Later research moved well beyond this snapshot. The follow-up work in [PR #17](https://github.com/BestNathan/narness-engineering/pull/17) explored two-phase readers, independent file-local runtimes, explicit stop control, bounded decision views, canonical localization results, and multiple exploration algorithms. Additional benchmark branches were opened as PRs #21-#25.
-
-Those branches are preserved as GitHub research history, but active development no longer happens in Narness.
-
-## Converged findings retained by Narness
-
-The durable conclusions are documented in the [System One Progressive Action Spaces topic](../../docs/topics/system-one-progressive-action-space/README.md). In short:
-
-- keep each model decision over a small grounded action frontier;
-- treat source reads as observations produced by typed effects;
-- separate broad file discovery from file-local navigation;
-- prefer independent file-local runtimes when raw observations would otherwise overwhelm one shared context;
-- keep navigation action generation content-agnostic where possible;
-- use `Choice` for mutually exclusive control flow and `Noul` for independent relevance/utility judgments;
-- do not overload relevance thresholds as implicit stopping semantics;
-- separate durable `RuntimeState` from bounded model-visible `DecisionView`;
-- keep execution traces separate from canonical localization results.
-
-## Historical scope of this directory
-
-The code and documents here reflect the early merged prototype, roughly:
-
-~~~text
-repository
-  -> directory relevance
-  -> file relevance
-  -> source-line relevance
-  -> merged snippets
-~~~
-
-That design is useful as provenance, but it has been superseded as an active architecture.
-
-Do not add new Code Locator algorithms, benchmark runs, or experiment logs here.

+Historical Narness development remains available through Git history and the closed research pull requests, especially #16 and #17.
 
-Narness may still absorb stable architectural conclusions from that work, but should not duplicate its implementation or experiment history.
+Do not add Code Locator source code, fixtures, tests, workflows, or run logs back under this directory. Stable cross-project conclusions may be incorporated into Narness topics instead.
