  * Ideally we would apply a size limit to the compressed overlay-base database,

  * Actions Cache client library. Instead we place a limit on the uncompressed
  * size of the overlay-base database.

- * Assuming 2.5:1 compression ratio, the 6 GB limit on uncompressed data would
- * translate to a limit of around 2.4 GB after compression.
+ * Assuming 2.5:1 compression ratio, the 15 GB limit on uncompressed data would
+ * translate to a limit of around 6 GB after compression. This is a high limit
+ * compared to the default 10GB Actions Cache capacity, but enforcement of Actions
+ * Cache quotas is not immediate.
+ *
+ * TODO: revisit this limit before removing the restriction for overlay analysis
+ * to the `github` and `dsp-testing` orgs.
