Review Summary
This PR successfully implements Sentry runtime exception capture for LiquidCortex with proper error handling and metadata enrichment. The changes are well-structured and maintain backward compatibility.
Key Changes:
- Added
_sentry_enabledflag with guarded initialization - Enhanced Sentry initialization with release version, package, and Julia version tags
- Implemented
_capture_runtime_exceptionhelper with nested error handling to prevent Sentry failures from affecting core functionality - Refactored
step!andensemble_step!functions to separate implementation from exception capture, maintaining clean separation of concerns
Technical Review:
- Error handling is comprehensive with proper guards to prevent Sentry initialization failures from blocking module load
- The refactoring pattern (separating
_step_impl!fromstep!wrapper) maintains the same logic while adding observability - Function scoping is correct -
_capture_runtime_exceptionis accessible to included files through module scope - Environment variable handling for
SENTRY_DSNfollows security best practices

Code Review
This pull request integrates Sentry error tracking into the simulation steps (step! and ensemble_step!) of LiquidCortex.jl. It wraps the core step implementations in try-catch blocks to capture and report runtime exceptions before rethrowing them. The review feedback points out a potential issue in the exception-capturing helper: restricting the exception argument to the Exception type can cause a MethodError if a non-Exception object is thrown in Julia, which would mask the original error. It is recommended to remove this type constraint.

Schedule runtime exception capture asynchronously with a short timedwait so a full Sentry.jl Channel cannot hang rethrow on step!/ensemble_step!. Move step! and ensemble_step! docstrings back onto the public wrappers.

- Add pollint=0.005 to timedwait so task-done check fires before 0.05s timeout - Allows early return when capture_exception completes quickly - Addresses Gitar performance review

Code Review ✅ Approved 3 resolved / 3 findingsImplements asynchronous Sentry runtime exception capture for LiquidCortex hot paths. The implementation addresses potential error masking for non-Exception throws, missing package version tags, and timing inconsistencies in the capture mechanism.
✅ 3 resolved✅ Edge Case: _capture_runtime_exception can mask original error for non-Exception throws
✅ Quality: pkgversion may be nothing, yielding release tag 'LiquidCortex.jl@nothing'
✅ Performance: timedwait pollint default (0.1s) exceeds the 0.05s timeout

Adds guarded runtime exception capture for LiquidCortex hot paths and enriches Sentry initialization metadata.\n\nCloses #18
Note
Low Risk
Observability-only wrappers around existing hot paths; capture is best-effort and bounded so failures still propagate unchanged.
Overview
Adds runtime exception reporting for GPU simulation entry points when
SENTRY_DSNis set, without changing simulation logic.Sentry init now sets a
releasefrom package version and tagsversion/julia_version, and tracks success in_sentry_enabled[].New
_capture_runtime_exceptionaccepts any thrown value (@nospecialize), runsSentry.capture_exceptionin@async, and onlytimedwaits ~50ms so a full Sentry queue cannot blockrethrow()on the hot path.step!andensemble_step!delegate to_step_impl!/_ensemble_step_impl!; the public APIs try/catch, capture, then rethrow. Ensemble stepping calls_step_impl!per lobe so inner failures are not double-reported.Reviewed by Cursor Bugbot for commit 0c1f053. Configure here.
