Week of February 9–15. 60 commits, 48 of them on chiefstaker.

On-chain code gets verbose fast: every instruction needs account validation, rent calculation, overflow checks, and tight size constraints. This week was mostly that — closing out the core staking flows, the SOL reward distribution, and the exponential weighting curve with enough test coverage that the next person to read it doesn't have to reverse-engineer it.

Also: 10 commits on cterm (polish + fixes), and single commits on integration-docs and replvar.
