# Check and inspect compiler truth

Compiler flags expose the parsed program, semantic model, project resolution, target check, truth report, and native bridge.

Inspect the earliest layer that disagrees with your intent instead of debugging only the final executable.

```yh
yehoc <project> --check
yehoc <project> --dump-ast
yehoc <project> --dump-sema
```


## Inspect a source project

Run these current compiler commands from the shared workspace. Replace demo with your project folder.

Verification: command reference

```sh
./yeho/build/dolphin-metal/yehoc ./demo --check --backend cpu-oracle
./yeho/build/dolphin-metal/yehoc ./demo --dump-project-json
./yeho/build/dolphin-metal/yehoc ./demo --dump-source-graph
./yeho/build/dolphin-metal/yehoc ./demo --dump-api-reference
./yeho/build/dolphin-metal/yehoc ./demo --dump-truth

```


Check validates without generating a binary.

Inspection output is a diagnostic contract and can evolve with the candidate edition.
