The provenance table gives one row per leaf with the winning layer. Passing --headed shows runtime.headed cli; exporting SDODS_HEADED=1 instead shows processEnv; with both it shows cli.
What I want in a support conversation is the other three-quarters of that: what did the env file say before the variable overwrote it, and what did the project file say before that. --json gives me the resolved tree, which is the same information in a different shape.
Is there a verbose mode, or a debug variable, that dumps the per-layer values rather than the collapsed result? Happy to post-process JSON, I just cannot find a source that has the history in it.
