📝 WalkthroughWalkthroughThe change adds compact molecule-name and atom-frame state helpers. Path collection now uses disk-backed molecule IDs and packed conflict masks. Strict stream validation and automatic cleanup are included. Tests cover storage, cleanup, conflicts, name deduplication, and reaction-event output. ChangesReaction path state
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The change reduces resident memory by moving Step 3 state to compact temporary mappings, but a failed second allocation can leave temporary data behind and a RAM-backed temporary directory can still consume limited filesystem memory. The PR is mergeable with explicit owner awareness and follow-up for these bounded cleanup and storage-environment risks. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

The conflict matrix stays all
Falsehere, so the test covers only the empty packed columns. The docstring states that packed conflict columns preserve ordered events. Callstore.conflict.markbeforefindreactionsto prove that a set bit reaches_getstepreactionand suppresses the reaction, which is the behavior that the packed representation must keep.💚 Suggested addition
store.conflict.mark( np.array([0]), np.array([0]), np.array([[True]]), )Assert the resulting CSV separately, because the marked step is filtered out.

APPROVE
I reviewed the complete four-file diff, the compact molecule-name table, disk-backed atom/frame store, packed conflict matrix, cleanup and error paths, repository guidance, existing review threads and replies, and the checks for this exact head. The new storage representations preserve the existing path/reaction semantics, use lossless dtypes, reject mismatched streams instead of silently truncating them, and are covered by focused regression tests including cleanup failures and conflict handling.
All relevant exact-head workflows and status checks are successful, and I did not find a high-confidence blocking issue or an unaddressed actionable inline finding.

Summary
Motivation
Step 3 previously kept two dense native-integer
N x stepmatrices in memory. On typical 64-bit builds,atomeachandconflictalone require about16 * N * stepbytes, before multiprocessing and temporary-array overhead. This makes large atom/frame combinations prone to out-of-memory failures even after result delivery is bounded.This change preserves the existing reaction and path semantics while moving the atom-frame state out of resident heap memory and reducing its representation size. It does not change output formats or public CLI options.

Scope
The atom-frame state remains proportional to
N x stepon disk. Further work can reduce remaining Step 3 scans and per-task copies independently; that is intentionally outside this PR.Summary by CodeRabbit
