For some really that really tingled my pleasure senses and I had immense joy solving it - took me a long time to understand its secrets but once I did it went pretty smoothly.
Thank you for setting and sharing!

Not too easy, not too hard. Interesting the key role that the given digit plays to disambiguate lots of things mid-solve. A-ha moment for sure.
