# UI Architecture Guards
This file maps each UI test to exactly one architecture rule.
The `compile` test target requires the `sql` feature because these guards cover
the complete SQL execution graph and its root diagnostics surface.
## Compile-Fail Guards (`tests/ui/**/*.rs`)
| `db/access_module_private.rs` | `db::access` is internal and must not be imported via deep paths. |
| `db/codec_module_private.rs` | `db::codec` decode/encoding internals are not public API. |
| `db/commit_module_private.rs` | `db::commit` recovery/marker internals are not public API. |
| `db/cursor_module_private.rs` | `db::cursor` continuation/token internals are not public API. |
| `db/canonical_row_not_public.rs` | `CanonicalRow` stays internal so arbitrary callers cannot acquire row-write capability. |
| `db/diagnostics_module_private.rs` | `db::diagnostics` module internals are not imported directly; use root re-exports. |
| `db/executor/grouped_budget_observability_module_private.rs` | Grouped budget observability internals are not publicly importable. |
| `db/executor/cannot_import_query_plan_planner.rs` | Executor boundary must not import planner internals (`db::query::plan::planner`). |
| `db/executor/kernel_module_private.rs` | `db::executor::kernel` internals are not public API. |
| `db/executor/load_module_private.rs` | `db::executor::load` internals are not public API. |
| `db/index_module_private.rs` | `db::index` internals are not imported directly. |
| `db/logical_plan_not_reexported.rs` | Internal planner symbol `LogicalPlan` must not be re-exported at `db` root. |
| `db/registry_module_private.rs` | `db::registry` internals are not imported directly. |
| `db/response_module_private.rs` | `db::response` module stays private; callers use root response types. |
| `db/session_module_private.rs` | `db::session` module internals are private; callers use `db::DbSession`. |
| `db/store_module_private.rs` | `db::data` store internals are not public API. |
| `query/grouped/handoff_module_private.rs` | Grouped handoff internals are not publicly importable. |
| `query/logical_plan_private.rs` | Query logical plan internals are not public via deep paths. |
| `query/plan_module_private.rs` | Query plan internals remain private; only root re-exports are public. |
| `visitor/normalize_module_private.rs` | Visitor normalization internals stay private. |
| `visitor/validate_module_private.rs` | Visitor validate internals stay private. |
## Compile-Pass Guards (`tests/pass/**/*.rs`)
| `db/execution_trace_root_import.rs` | `ExecutionTrace` diagnostics surface is available via `db` root re-exports. |
| `db/session_root_import.rs` | `DbSession` is available via `db` root public API. |
