### FreshCredit Impact
85-
**GOOD NEWS**: FreshCredit only uses `libsql` and `libsql_replication` client crates, which already compile successfully with this migration. The server binary issues don't affect FreshCredit's usage.
115+

87-
### Next Steps for FreshCredit
88-
1. ✅ **IMMEDIATE**: Use the updated client crates (`libsql`, `libsql_replication`)
89-
2. ⏸️ **SHORT-TERM**: Wait for upstream to fix FFI linking issue
90-
3. ⏸️ **LONG-TERM**: Consider contributing H2C re-enablement
117+
## FreshCredit Impact
118+
119+
### ✅ READY FOR USE
120+
121+
FreshCredit only uses `libsql` and `libsql_replication` client crates, which compile successfully. The migration is complete and ready for FreshCredit's use.
122+
123+
### What Works
124+
- libsql client crate
125+
- libsql_replication crate
126+
- sqld binary (for local development/testing)
127+
128+
### What's Disabled (Not Needed by FreshCredit)
129+
- SQL extensions (regexp, crypto, etc.)
130+
- H2C upgrade support
131+
- Admin dump from URL

## Next Steps
145+
146+
### For FreshCredit (Immediate)
147+
1. ✅ Use the updated client crates
148+
2. Update Cargo.toml to point to this fork
149+
3. Test with your application
150+
151+
### For Future (Optional)
152+
1. Re-enable sqlean-extensions (fix pcre2 compilation)
153+
2. Re-implement H2C support with Hyper 1.0
154+
3. Clean up compiler warnings
155+
4. Contribute changes back to upstream
