What are spent sats?

The sat ranges of already-spent outputs, which blockspace.to's ord fork keeps.

Here, spent sats means the sat ranges of outputs that have already been spent. blockspace.to, a Blockspace Labs product, runs a fork of ord with --index-spent-sats, so a spent output still answers with its sat ranges; an ord without that flag cannot. BTI's August 2026 handoff notes name CAT-21 as the only normal-operation consumer of those ranges.
