🔴 (08:45) User-provided source documentation states that streaming commands render each yield immediately, while output handling associated with the return value runs only on the return value—never on individual yields.
🔴 (08:45) User-provided source defines const LOG_LEVEL_KEY = "log-level" and documents the injected --log-level flag as always stripped before the command function runs.
🔴 (08:45) User-provided source states that injected wrapper flags designated as always stripped are removed so the command never sees them.
🔴 (08:45) User-provided source states that the relevant output flag is always injected when output: { human: ... } is configured, regardless of other conditions described nearby.
🔴 (08:45) User-provided source documents a hidden --verbose flag injected into every command by buildCommand, while noting collision handling when a command already defines its own verbose flag, such as the api command.
🔴 (08:45) User-provided source states that wrapper logic intercepts injected flags before the original func runs and calls setLogLevel().
🔴 (08:45) User-provided source documents OutputConfig<T>.human as contravariant in T; the builder erases T because it does not know the output type, and uses any so commands can declare OutputConfig<SpecificType> while the wrapper handles output generically.
🔴 (08:45) User-provided source states that a raw string flag value is pre-parsed by the wrapper into a string[] before command execution.
🔴 (08:45) User-provided source states that project-related global handling yields to command-owned flags such as release create --project; those command-owned flags pass through to func().
🔴 (08:45) User-provided source shows const projectTrimmed = commandOwnsProject ? undefined : project?.trim();, preventing global project processing when the command owns project.
🔴 (08:45) User-provided source states that explicit CLI project-related values outrank environment variables and overwrite existing environment variables.
🔴 (08:45) User-provided source states that command documentation is enriched with a JSON-fields section when a schema is registered on the output configuration; the enrichment path returns early when !outputConfig?.schema.
🔴 (08:45) User-provided source defines VERBOSE_FLAG within an injected-flags collection and separately defines a collection of flags that are always stripped before command invocation.
