📝 WalkthroughWalkthroughThe pull request adds lifecycle generation checks for persisted collections, scopes Electric synchronization state to collection lifecycles, fixes query ownership cleanup, adds live-query facade metrics and include coverage, validates query planning, and lazily initializes runtime identities. ChangesPersistence lifecycle generations
Electric synchronization lifecycles
Query ownership and live facades
Lazy runtime identity
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The PR hardens asynchronous collection and resume handling, but the current implementation can still terminate a restarted synchronization, block mutation acknowledgements, or persist and reuse state before a replacement snapshot is confirmed. These bounded correctness and availability risks make the PR not merge-ready until they are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

702-702: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueDistinguish the renamed test pairs by name.
Three pairs of tests now carry names that state the same behavior:
- Line 702 "should use the key map of the biggest collection when inner-joining" and line 799 "should optimize an inner join with the biggest collection's key map".
- Line 889 "should use the right collection key map when left-joining" and line 1003 "should optimize a left join with the right collection key map".
- Line 1091 "should use the left collection key map when right-joining" and line 1180 "should optimize a right join with the left collection key map".
The bodies still differ: one member of each pair also has an explicit index on the join key, and the other does not. Add that distinction to the names, for example "…with an existing join-key index" and "…without a join-key index". This keeps the suite readable when a test fails.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Indent the wrapped "Killed by" lines so they stay inside their list items.
In items 1, 2, and 4, the continuation lines start at column 0. Markdown ends the list item content at that point, so the quoted test names render as separate top-level paragraphs and lose the link to the numbered mutation. Items 3 and 4 show the intended indentation for the first continuation line.

Keep the active-ownership cache-removal case.
query1.cleanup() releases the acquisition before removeQueries(). The test does not execute the positive-refcount return in cleanupQueryIfIdle at packages/query-db-collection/src/query.ts Line 1946. Remove the cache entry while query1 is active. Assert that its rows remain. Then clean up query1 and assert that its rows are removed.

Retain the per-collection lifecycle binding across cleanup. A cleaned-up collection can restart through startSync(). Cleanup deletes its binding, so a later materialization from the same options can share its ElectricLifecycle; start() then retires the restarted collection’s lifecycle, rejects its pending waiters, and causes its stream to drop later batches.

This hardens collection lifecycle boundaries across core DB, SQLite persistence, Electric, and query-backed collections. Stale async work can no longer cross collection lifecycles, unsafe resumed updates fail closed, and owned query rows remain available without adding a user-facing API.
Reviewer guidance
Root cause
Adapter state could outlive the collection lifecycle that created it. Electric evidence, mutation matches, transaction waiters, reset work, and persisted hydration were split across descriptor state, lifecycle maps, and stream closures. Cleanup and automatic garbage collection did not retire every path consistently, so late work could affect a restarted lifecycle or another collection built from the same descriptor.
Resume processing also assumed every partial
updatehad a complete base row. That assumption depended on persistence hydration, callback boundaries, and move-out bookkeeping. A valid history could change meaning when split across callbacks, while a deleted row could remain marked as known.Query-backed collections had a separate ownership mismatch: cache removal could retire rows while an eager or active acquisition still owned them. Persisted ownership metadata could also be staged before an insert that cleared metadata for the same key.
Approach
getKeycode is never inspected or called as field metadata.Key invariants
Non-goals
keyPathAPI and does not infer key fields from function source or runtime probes. Queries continue to use declared indexes or the existing scan fallback.Trade-offs
