Inline comments:
In `@stelae-cardano/src/backfill.rs`:
- Around line 490-508: Update backfill::run and its Mithril operations to avoid
calling Handle::block_on from an asynchronous Tokio context: either provide an
async entry point and await the operations, or explicitly document and enforce
the synchronous-only precondition before execution. Preserve the existing
cancellation and error propagation behavior around latest_immutable_file.
In `@stelae-cardano/src/initialize.rs`:
- Line 224: Update the existing-storage branch around has_existing_data and
Outcome::Existing so committed storage without a matching marker is rejected
rather than entering run backfill. Validate the marker against the storage path,
network magic, and source before returning Outcome::Existing; alternatively
implement the required validated legacy-adoption flow that records it. Add a
regression test covering unmarked storage with a committed cursor.
In `@stelae-publisher/src/main.rs`:
- Around line 186-188: Update the explicit configuration handling around
explicit.and_then(Path::to_str) so a non-UTF-8 --config path produces an error
and stops startup instead of being ignored. Preserve the required file
registration for valid UTF-8 paths, and use the surrounding
configuration-loading function’s existing error propagation mechanism.
