Does Substrate Archive only index finalized blocks? What about chains that do not support finalization?

Substrate Archive is finality-agnostic. It directly indexes blocks from the backend database of a Substrate chain; any and all blocks added to the database backend will be indexed by Substrate Archived. For chains that use Substrate's GRANDPA finalization gadget, only finalized blocks are recorded in the backend database and, as such, only finalized blocks will be indexed by Substrate archive.

How do I debug substrate-archive?

First, you can check the logs for anything that might have gotten wrong. Substrate Archive stores logs in the Data Local Directory:

Platform	Value	Example
Linux	$XDG_DATA_HOME or $HOME/.local/share/substrate_archive/	/home/alice/.local/share/substrate_archive/
macOS	$HOME/Library/Application Support/substrate_archive/	/Users/Alice/Library/Application Support/substrate_archive/
Windows	{FOLDERID_LocalAppData}\substrate_archive\	C:\Users\Alice\AppData\Local\substrate_archive\

Alternatively, if you are running polkadot-archive or node-template-archive you can see debug logs with -vvv (DEBUG mode) or -vvvv (TRACE mode)
