With the v2→v3 migration sweeping stale `__run__*` branches off `__manifest` on first read-write open, the defense-in-depth `is_internal_run_branch` guard is no longer needed. - delete `db/run_registry.rs`; drop the module + re-export from `db/mod.rs` - collapse `is_internal_system_branch` to the schema-apply-lock check only - `ensure_public_branch_ref`: drop the run-ref rejection; `__run__*` is now an ordinary branch name - `branch_merge`: reject `is_internal_system_branch` (was run-only) so the schema-apply lock is rejected consistently with create/delete — a small, deliberate tightening - update the inline schema-apply test + the writes integration tests (`public_branch_apis_reject_internal_run_refs` → `public_branch_apis_reject_internal_system_refs`, which also asserts `__run__*` now creates successfully) - docs: flip the "pending production sweep / defense-in-depth" notes to "auto-swept by the v2→v3 migration"; document the read-only-open limitation Known residual: the inert `_graph_runs.lance` / `_graph_run_actors.lance` bytes remain until a `StorageAdapter::delete_prefix` primitive lands.
