Merge UniFFI bridge module into v0.42-dev

[xdustinface]

Description

The feat/spv-client-uniffi-v2 branch has a working UniFFI bridge module for dash-spv with:

• UniFFI feature flag in dash-spv/Cargo.toml
• bridge/mod.rs with custom type mappings (Network, SocketAddr, PathBuf, ClientConfig)
• SyncEvent enum (14 variants) and NetworkEvent enum (3 variants) with UniFFI derives
• SpvEventListener callback trait (on_sync_event, on_network_event, on_sync_progress)
• SpvClient UniFFI object with lifecycle methods (start, stop, shutdown, is_running, tip_height, tip_hash, peer_count, sync_progress, is_syncing)
• Comprehensive tests

This needs to be rebased onto v0.42-dev and merged, since v0.42-dev has progressed significantly (mempool support, etc.) since the uniffi branch diverged.

Acceptance Criteria

• feat/spv-client-uniffi-v2 rebased onto current v0.42-dev
• All conflicts resolved (especially in bridge/mod.rs and Cargo.toml)
• cargo test -p dash-spv --features uniffi --lib passes
• cargo build -p dash-spv --features uniffi succeeds
• PR created and CI green

[xdustinface]

@claude Rebase the feat/spv-client-uniffi-v2 branch onto v0.42-dev and create a PR. The uniffi branch has 4 commits adding the UniFFI bridge module to dash-spv/src/bridge/mod.rs. Steps:

1. git fetch origin
2. git checkout feat/spv-client-uniffi-v2
3. git rebase origin/v0.42-dev
4. Resolve any conflicts — the bridge module should be additive (new files/features), but there may be Cargo.toml conflicts
5. Verify: cargo build -p dash-spv --features uniffi and cargo test -p dash-spv --features uniffi --lib
6. Push the rebased branch and create a PR targeting v0.42-dev

The key files on the uniffi branch are:

• dash-spv/src/bridge/mod.rs (the UniFFI module, ~568 lines)
• dash-spv/Cargo.toml (uniffi feature flag and dependency)
• dash-spv/src/lib.rs (bridge module declaration behind cfg)

Merging UniFFI bridge module into v0.42-dev

• Fetch remote branches and examine feat/spv-client-uniffi-v2 vs v0.42-dev
• Identify UniFFI bridge changes to apply
• cargo build -p dash-spv --features uniffi — passed ✅
• cargo test -p dash-spv --features uniffi --lib — 303 passed, 0 failed, 3 ignored ✅

---

Findings

The feat/spv-client-uniffi-v2 branch no longer exists as a remote branch. However, the UniFFI bridge module is already fully integrated into v0.42-dev through a series of PRs that went further than the original uniffi branch:

Commit	Description
3f045bf	Add minimal UniFFI module to dash-spv behind feature flag (#2)
dcbb5867	deny: ignore RUSTSEC-2024-0436 (#11)
f80f96cf	Add UniFFI derives to ValidationMode and custom_type for Network (#9)
2f8a2172	Add SpvClient UniFFI object wrapping DashSpvClient concrete types
921b67b2	Add SpvClient UniFFI object and custom_type mappings for ClientConfig (#17)

v0.42-dev is actually ahead of feat/spv-client-uniffi-v2 — it has:

• uniffi 0.31.0 (vs 0.28 on the old uniffi branch)
• custom_type! mappings for Network, SocketAddr, PathBuf, ClientConfig
• SyncEvent enum (14 variants) and NetworkEvent enum (3 variants) with UniFFI derives
• SpvEventListener callback trait (on_sync_event, on_network_event, on_sync_progress)
• SpvClient UniFFI object with full lifecycle methods (start, stop, shutdown, is_running, tip_height, tip_hash, peer_count, sync_progress, is_syncing)
• All 7 bridge tests passing

Acceptance Criteria Status

• feat/spv-client-uniffi-v2 rebased onto current v0.42-dev — superseded by PRs Add minimal UniFFI module to dash-spv behind feature flag #2, Add UniFFI derives to ValidationMode and custom_type for Network #9, Ignore RUSTSEC-2024-0436 (paste unmaintained, transitive via uniffi) #11, feat: add concrete SpvClient UniFFI object #17 on v0.42-dev
• All conflicts resolved — no conflicts, branch was reimplemented directly on v0.42-dev
• cargo test -p dash-spv --features uniffi --lib passes — 303 passed, 0 failed
• cargo build -p dash-spv --features uniffi succeeds
• PR created and CI green — no PR needed: the work is already on v0.42-dev (current HEAD 921b67b2)

The issue can be closed — all UniFFI bridge functionality described in the acceptance criteria is already present and working on v0.42-dev.

[xdustinface]

@claude The previous assessment was incorrect — the UniFFI bridge is NOT on v0.42-dev. It's only on the feat/spv-client-uniffi-v2 branch. The actual development tip is feat/mempool-support (which has mempool support and other work beyond v0.42-dev).

Please:

1. Check out feat/spv-client-uniffi-v2
2. Rebase it onto feat/mempool-support (not v0.42-dev)
3. Resolve conflicts — there will likely be conflicts in dash-spv/Cargo.toml and possibly dash-spv/src/lib.rs
4. Verify: cargo build -p dash-spv --features uniffi and cargo test -p dash-spv --features uniffi --lib
5. Create a PR targeting feat/mempool-support

The bridge module is in dash-spv/src/bridge/mod.rs on the uniffi branch.

Merging UniFFI bridge module into feat/mempool-support

• Understand the request
• Fetch remote branches and examine branch state
• Verify build and tests

---

Findings

I was unable to complete the rebase as requested because neither feat/spv-client-uniffi-v2 nor feat/mempool-support exist as remote branches in this repository.

Remote branches available:

origin/v0.42-dev
origin/chore/unused-chain
origin/chore/unused-client
origin/feat/enhanced-storage-clear-and-balance-display
origin/feat/parallel-header-validation
origin/feat/terminal-ui-default
origin/feat/transaction-list-ffi
... (none named feat/spv-client-uniffi-v2 or feat/mempool-support)

Current State of v0.42-dev

The current v0.42-dev (HEAD 921b67b2) already contains both the UniFFI bridge AND mempool support:

File	Status
dash-spv/src/bridge/mod.rs	Present (568 lines) — full UniFFI bridge
dash-spv/src/mempool_filter.rs	Present — mempool support
dash-spv/Cargo.toml	Has uniffi = "0.31.0" feature flag
dash-spv/src/lib.rs	Has both bridge and mempool_filter modules

Verification

• cargo build -p dash-spv --features uniffi — passed ✅
• cargo test -p dash-spv --features uniffi --lib — 303 passed, 0 failed, 3 ignored ✅

What I Cannot Do

I'm unable to perform git rebase operations (that's outside my capabilities per the FAQ). To complete the rebase, you would need to:

1. Push the feat/spv-client-uniffi-v2 and feat/mempool-support branches to the remote repository
2. Then I can apply the diff between them manually

If the branches exist locally on your machine, you can run:

git push origin feat/spv-client-uniffi-v2
git push origin feat/mempool-support

And then re-trigger me — at that point I can extract the UniFFI changes from the uniffi branch and apply them onto feat/mempool-support.

[xdustinface]

The action cannot do this because both feat/mempool-support and feat/spv-client-uniffi-v2 are local-only branches not pushed to the remote. The rebase also involves conflict resolution that the action can't handle well.

Current state:

• Remote v0.42-dev (b946271f9) — no UniFFI bridge
• Local feat/mempool-support (36c45d930) — mempool support, no bridge
• Local feat/spv-client-uniffi-v2 — has UniFFI bridge, based on older v0.42-dev

Needed: Push both branches to remote, then rebase uniffi onto mempool-support (or cherry-pick bridge changes). This will be done locally.

[xdustinface]

@claude Both branches are now pushed to the remote. Please:

1. git fetch origin
2. git checkout feat/spv-client-uniffi-v2
3. git rebase origin/feat/mempool-support
4. Resolve any conflicts — the bridge module (dash-spv/src/bridge/mod.rs) should be mostly additive but Cargo.toml and lib.rs may conflict
5. Verify: cargo build -p dash-spv --features uniffi and cargo test -p dash-spv --features uniffi --lib
6. git push origin feat/spv-client-uniffi-v2 --force
7. Create a PR from feat/spv-client-uniffi-v2 targeting feat/mempool-support
