Review Change Stack

Warning

Review limit reached

@luckysori, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 39 minutes

Limit details: You’ve used all 1 included review currently available under your plan.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Walkthrough

The regtest workflow and justfile now start only the emulator profile. Failure logs exclude Boltz and Lightning containers. Boltz-related test comments now reference the Boltz regtest environment and setup script.

Changes

Regtest configuration

Layer / File(s) Summary
Emulator-only regtest startup
.github/workflows/e2e-core.yml, justfile
Regtest startup uses only the emulator profile. The workflow description and failure logging now cover the core regtest stack.
Boltz test prerequisites
e2e-tests/tests/boltz_*.rs
Boltz-related test comments reference the Boltz regtest environment and scripts/boltz-setup.sh.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to c9125

The PR changes E2E test selection but still allows Boltz tests to run in emulator-only jobs, where their required service profile is not started. This can produce failed or misleading CI validation, so the change needs correction before merge.

Separate Boltz test selection from emulator-only startup.

Both execution paths still run ignored Boltz tests while starting only the emulator. Core runs must filter Boltz tests, and Boltz runs must start a separate Boltz profile. (raw.githubusercontent.com)

  • .github/workflows/e2e-core.yml#L83-L86: filter Boltz binaries from the emulator-only matrix, or use a separate Boltz job.
  • .github/workflows/e2e-core.yml#L105-L105: remove Boltz log exclusions only after the core matrix cannot run Boltz tests.
  • justfile#L10-L12: make e2e-tests exclude Boltz tests before retaining the emulator-only profile.

PROTOCOL-CRITICAL: human review required.

Summary

This PR excludes Boltz e2e tests from standard CI by renaming them from e2e_boltz_*.rs → boltz_*.rs, so their compiled binaries fall outside the e2e_* glob used by the find-binaries step. It also simplifies the regtest stack startup to always use --profile emulator only. The protocol-critical test logic in boltz_reverse_vhtlc_unilateral_exit.rs is unchanged — only the filename and the environment-setup comment are modified.


Findings

1. scripts/boltz-setup.sh referenced but does not exist — .github/workflows/e2e-core.yml (indirectly), e2e-tests/tests/boltz_reverse.rs:22, e2e-tests/tests/boltz_reverse_vhtlc_unilateral_exit.rs:25, e2e-tests/tests/boltz_submarine.rs:22

The three #[ignore] tests now carry the comment:

// Requires the Boltz regtest environment. See scripts/boltz-setup.sh.

No scripts/boltz-setup.sh exists in the repository. A developer who wants to run these tests locally follows a dead reference. This is a documentation gap only (no correctness impact), but since the whole point of the PR is to explain how to run these tests out-of-band, it matters. The script should be added or the comment should point to wherever the actual setup instructions live.

2. Exclusion mechanism is implicit — e2e-tests/tests/ (naming convention)

The binary exclusion relies entirely on the naming rule: "CI picks up e2e_* binaries; anything else is silently skipped." This is not documented in the workflow or in the test files. If a future contributor adds a new Boltz test named e2e_boltz_new.rs, it would again be picked up by CI without the Boltz stack running, resulting in silent test failures or false passes (the tests are #[ignore], so they'd be skipped — but the naming invariant could be broken in the other direction too). A comment in the workflow's find-binaries step stating the convention explicitly would prevent drift.

3. chmod +x target/debug/deps/e2e_* — .github/workflows/e2e-core.yml (post-merge line ~82)

After the rename, the boltz_* binaries won't receive the chmod +x. This is benign today because those binaries are not in the matrix (the find step doesn't pick them up), but it is a latent inconsistency worth noting if the chmod step is ever audited.


Protocol correctness — boltz_reverse_vhtlc_unilateral_exit.rs

The unilateral exit path tested here is:

  1. VHTLC funded and claimed via reverse swap
  2. build_unilateral_exit_trees → broadcast_next_unilateral_exit_node in sequence, each node confirmed before the next (P2A fee-bump dependency is correctly handled)
  3. Relative timelock satisfied via set_outpoint_block_height_offset / set_outpoint_blocktime_offset
  4. create_send_on_chain_transaction exercised, result verified with bitcoinconsensus::verify across all inputs

No logic changes in this file. The test structure is sound: tokio::select! with a 120 s timeout guards the VHTLC wait; the spending loop is bounded by the tree depth; the bitcoinconsensus::verify call at the end provides a consensus-layer correctness check. No issues observed.


Non-issues (confirmed clean)

  • SECURITY.md: whitespace-only alignment change. PGP fingerprints and URLs are unchanged.
  • Removal of Boltz containers from the failure-log loop is correct and complete.
  • justfile regtest_profiles change is consistent with the CI change.
  • The #[ignore] attribute is retained on all excluded tests — they cannot run accidentally.
