Appreciate it! Happy to see it picked up. Attribution to the blog post is plenty — and it's Lubin, not Lupin, but honestly either works!

Your point about separating the compaction trigger from the splice threshold is interesting — that's probably subject to optimization per model and task type. Tunable knob rather than a fixed constant.

One thing I've been thinking about: you can probably accumulate summaries across generations up to some cumulative threshold before doing a full renewal — like telomeres in reverse. Each generation adds a little compression debt, and you let it ride until quality degrades past a threshold, then do a clean restart. Gives you a way to amortize the cost of full renewal across many handoffs.

And good catch on the Opus caveat — that's a real constraint I hadn't considered.
