Finalized and opened the PR making the sender generic over typestate Sender generic over typestate #728 .
Next focus: update the receiver to return state transition objects and persist session events.
Wrote unit tests for session replays and session history object.
Helping where he can with Liana integration blockers
Action Item: design an interface to expose fallback transactions in sketch branch.

Last week, attempted to fix the danger_local_https build with all features enabled. New plan: rename the flag to manual_tls_flag. It’s not as dangerous as initially thought.
Proposed logic change: always force manual TLS when the flag is active.
Started simplifying relay management; found inconsistencies in tests.
Wrapped up work on sender mutants but identified some open-ended questions
This week: expand mutants across the entire sender module. Once complete, revisit the overall mutant strategy Add mutants for sender module #717
Discovered that forcing cargo-mutant to use all tests (including E2E and FFI) yields no surviving mutants.
No major blockers.
Potential bottleneck: review bandwidth. Dan is the only reviewer right now; Ben could pick up review duties on smaller PRs.
Note on FFI dependencies: previously depended on bitcoin-ffi. To get Python bindings working, switched to Ben’s branch for access to PSBT FFI exports. Plan to move back to upstream.
- Ongoing discussion on proper error propagation. Returning errors as strings loses structure.
- Plan to draft a few approaches for structured error handling.
- Need to identify areas where programmatic error handling is critical.

@thebrandonlucas ’s CLI PR merged successfully Refactor config to use proc macros over builder #703
Improved consistency in Payjoin blog messaging and diagrams.

Provided assistance with BDK CLI and Bitcoin Core integration.
Didn’t prioritize fundraising or operational work last week. Instead prioritized reviews and integrations.
Goal: get Spacebear focused on unblocking integrations and reviews to free up Dan’s time for operational tasks.
Identified that rust-payjoin FFI has a different MSRV compared to the workspace Bring payjoin-ffi into top level workspace #721 . To unify, we need to align MSRVs. We decided to keep FFI excluded from the main workspace. More details in Bring payjoin-ffi into top level workspace #721
Noted the need for a dedicated FFI expert; currently, there’s no clear owner. Team should keep an eye out for a potential candidate.
Success this week: aim to spend at least one day off review work without becoming a blocker.
