[review-p0-bugs] fix: core and react review fixes - #31
Merged

Conversation
Remove the obsolete Vite pre-commit hook that invokes the retired vp staged command. This prevents local commits from depending on an unavailable hook command.
Remove the retired Vite staged-file configuration and its prepare script. This completes the hook removal without requiring unavailable local commands.
Prune registry entries by container identity so same-named classes cannot remove each other's entries. Avoid recording or retaining dependency edges when an owner has already been disposed, and cover both ownership cases.
Sweep uncommitted render dependencies, refresh selections on every render, and resubscribe when a provider registry changes. Add regressions for SSR, selector prop changes, and registry swaps, with release notes for each fix.
Record the completed P0 fixes and their regression coverage in the review and follow-up checklist. Keep the remaining P1 work and verification tasks visible for subsequent changes.
A time-sliced render can yield between render and commit, so the microtask sweep disposed the instance before the commit claimed it. The sweep now waits unownedSweepDelayMs (default 5000) and restarts when a render re-acquires the pending entry.
Resolve per-class equality at construction, always run [INIT_CONFIG] in createCubitStub, and apply stub state to any StateContainer.
Registry read paths and hasInstance, shared StateContainer change bookkeeping, lazy plugin state bridge, per-registry plugin managers, flush() draining until idle, keepAlive: false override, and removal of unused types and registerType.
Rebind reassigned methods and add a set trap in the tracked proxy, key the useBloc memo on the resolved instance key, verify the acquired dep in reconcile pass 2, and pass BlocProvider args changes through.
The framework symbols and the registry's insertInstance (now the symbol-keyed INSERT_INSTANCE method) are no longer exported from the main entry.
DepSession owns the per-render dep entries, the commit-time reconcile and the unmount cleanup; expandWithAncestors gets its own module.

Update the configuration option count.
This row adds unownedSweepDelayMs, but the introduction at Line 160 still says the config object has four keys. Update that count so readers do not overlook the sweep setting. Fascinatingly, the table already gives the correct default.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Distinguish temporary setup from rendering.
withTestRegistry temporarily changes the core registry slot while it creates stubs. It restores the slot before rendering. Therefore, “never change the global registry” is inaccurate. State that rendering does not leave the global registry changed, while setup temporarily scopes core helpers. This distinction is logical.

Clear sweep timers when ownership changes or disposal prunes an entry.
_scheduleSweep uses a normal setTimeout whose closure retains entry and its instance. _pruneEntry does not cancel that timer. Direct disposal can therefore retain the disposed instance and can keep a Node SSR or test process alive for the default 5000 ms.
When an existing entry gains a ref or dependent, clear its timer. If a caller supplies both sweepIfUnowned: true and an ownership option, the current condition can also restart the timer after the entry becomes owned.
Suggested fix
private _pruneEntry(
Type: StateContainerConstructor,
container: StateContainer<any, any, any>,
): boolean {
const entry = this._entryByInstance.get(container);
if (entry === undefined) return false;
+ clearTimeout(entry.sweepTimer);
+ entry.sweepTimer = undefined;
this._entryByInstance.delete(container); this._syncActivation(entry);
- if (options.sweepIfUnowned && entry.sweepTimer !== undefined) {
+ if (!this._hasNoOwners(entry)) {
+ clearTimeout(entry.sweepTimer);
+ entry.sweepTimer = undefined;
+ } else if (options.sweepIfUnowned && entry.sweepTimer !== undefined) {

Restore NODE_ENV in a finally block.
If manager.install or the assertion fails, the test skips its cleanup. The registry hooks do not restore process.env, so later tests in the same worker can observe the modified value. In the supported Node runtime, assigning undefined stores the string "undefined".
Suggested fix
delete process.env.NODE_ENV;
-
- manager.install(
- { name: 'test-plugin', version: '1.0.0' },
- { environment: 'development' },
- );
-
- expect(manager.hasPlugin('test-plugin')).toBe(false);
-
- process.env.NODE_ENV = originalEnv;
+ try {
+ manager.install(
+ { name: 'test-plugin', version: '1.0.0' },
+ { environment: 'development' },
+ );
+
+ expect(manager.hasPlugin('test-plugin')).toBe(false);
+ } finally {
+ if (originalEnv === undefined) delete process.env.NODE_ENV;
+ else process.env.NODE_ENV = originalEnv;

Update the test around manager.install to restore process.env.NODE_ENV in a
finally block, whether installation or the assertion succeeds or fails. Restore
the original value exactly: delete NODE_ENV when originalEnv was undefined, and
otherwise reassign originalEnv.

A non-speculative acquire (ensure, out-of-render dep access) now cancels a pending speculative sweep, and the sweep timer no longer keeps a Node process alive after SSR.
