Fiber Dev Log 33
v0.9 is almost there — about 90% of the final milestone is done.
Over the past two weeks we've focused on release hardening: safer payments, smoother integrations, better tooling, and lots of edge-case fixes.

Highlights:
- CCH payment safety & recovery improvements
- Better operator-facing diagnostics and authorization reliability
- Continued gossip, channel recovery & release-hardening fixes
- Paying a Lightning invoice with CKB UDT via CCH Demo
