Analysis and metering
Governed by: docs/design/specs/2026-07-15-plugin-catalog-tiered-packaging.md
59 plugins, 34 of them cleared to run on the console's own audio thread. Figures are at 96 kHz; the columns are explained on the catalog index. Sorted by hosting verdict, then by name.
2 of them declare no LV2 category at all and are filed here from their own name or description — our reading, not the plugin's claim.
