+## #428 — Sky lightning slot fired 3 CreateParticle hooks with no live pose after a TimeSync day-group flip
+
+**Status:** OPEN
+**Severity:** LOW (bounded diagnostic spam; no crash, no leak)
+**Filed:** 2026-08-23 (launch11.err, first production run of the sky default-script port)
+**Component:** sky / vfx / script lifecycle
+
+**Symptom:** three identical stderr lines during the startup TimeSync window:
+`vfx: No live effect pose for owner 0xF8000007, part 0; emitter 0x320002C2 was not created.`
+Owner `0xF8000007` = post-scene sky slot index 7 — the Rainy lightning carrier
+(`0x02000BA6`, PES `0x33000453`, whose t=0 hooks are a `CallPES` self-loop
+(pause 30) plus `CreateParticle 0x320002C2 part=0`). The client boots on the
+pre-sync default calendar (PY10 day0, group 16 Rainy); the first TimeSync flips
+to the server date and the lightning slot vanishes, and hook executions landed
+AFTER `SkyPesFrameController` had already removed the slot's pose.
+
+**Analysis so far:** `PhysicsScriptRunner.StopAllForEntity` purges owners,
+anchors AND `_delayedCalls`, so this cannot loop forever (observed exactly 3,
+consistent with hooks already drained into the sink's queue, or an ordering
+window between the controller's stop and the runner's tick inside the same
+frame). Worth pinning: whether hook dispatch can outlive the owner's stop by
+one tick, and whether `part=0` hooks against a root-only synthetic pose (empty
+part list) resolve to the root as retail would. Repro: launch while the server
+clock is far from the pre-sync default during a Rainy-window fraction; watch
+stderr through the first TimeSync.
+
+**Files:** `src/AcDream.App/Rendering/SkyPesFrameController.cs`;
+`src/AcDream.Core/Vfx/PhysicsScriptRunner.cs` (`StopAllForEntity`, tick order);
+`src/AcDream.Core/Vfx/ParticleHookSink.cs` (`TryResolveAnchor`, part fallback).

 ## #28 — Aurora ("northern lights") effect not rendered
 
-**Status:** FIX LANDED 2026-08-23 — awaiting the connected visual gate
+**Status:** DONE — connected gate USER-PASSED 2026-08-23 (commit `18fce7bb`).
+The accepted residual: the aurora reads somewhat more intense in acdream than
+retail — the emitters are verbatim; the delta is the linear-light compositing
+(+ optional Atmospheric-pack bloom) brightening faint additive glows over a
+dark sky vs retail's gamma-space add. Accepted by the user ("gate pass for
+now. Might reopen it!") — if reopened, the principled fix is a gamma-faithful
+compensation on ADDITIVE particle contributions, never an aurora-only factor.
