+# QA2: demonstrated cold-feed refresh gap (client7 routed)
+
+Dispatch16:08:41 classified this as a hard local-review blocker and routed a method-only actual-service
+regression/fix to client-reliability-7. QA is product-read-only and holds browser closed until durable fix+
+refreshed built artifact. No forced refresh/render is an acceptable baseline substitute.
+
+## Trigger and observation
+
+Fresh actual app at1b3ef49c/build1834b6a9,empty browser cache,existing local mock relay preseeded3 synthetic
+kind30078 video events. Hosted media is genuine local VP8 with real HEAD/GET/Range semantics;crypto uses genuine
+canonical toolkit and local pinned Buffer mirror. Runtime artifact,external deny guard,inputs and3-card15s bound unchanged.
+
+Granted targeted passive run16:06:34.174→16:06:51.787Z(17.613s),Chromium154.0.8037.97,360×800:
+- Actual local relay video REQ returns3 EVENTs plus EOSE;client and app caches contain3.
+- Actual getFilteredActiveVideos returns3;all3 shouldIncludeVideo and canAccess decisions aretrue.
+- No private,NSFW,deleted,invalid,author-blocked or event-blacklisted flags. Whitelistfalse,lockdownfalse,hydratedtrue.
+- Passive service chronology:initial videos:updated cache count0,then videos:cache size3 and videos:updated subscription count3.
+- View remains currentVideos0,renderedIDs0,last signature__EMPTY__,metadata.reason=cache;actualDOM cards0 after15s.
+- View container connected and matches activevideoList;bodynotinert,documentvisible. This rules out the measured
+  access/private/NSFW/blacklist and mount/visibility candidates for this reproduction.
+
+[Actual empty styled Trending screenshot](playback-qa-2-render-diagnostic.png)
+
+First missing observed notification/render boundary is after allowed subscription data enters the service/appmap.
+Source:js/services/nostrService.js loadVideos applyAndNotify invokes onVideos for cache/optimistic paths;
+live subscription callback caches/emits but never invokes that callback. js/app/feedCoordinator.js onVideos owns
+refreshFeed/render;applicationBootstrap binds subscription:changed but not videos:updated for main-feed rendering.
+This is the minimal owner/file boundary sent to dispatch,not a product edit by QA. Client7 owns reproduction/fix.
+
+## Fidelity and interventions
+
+Original diagnostic seed omitted canonical s tag. Actual schema rejects that omission,while actual converter and
+service eligibility accept all3,and wire/ingest/allow decisions are measured. Thus this schema mismatch did not
+prevent the observed ingestion/eligibility and must not be presented as the empty-render cause. The post-fix
+baseline should retain the established canonical fixture shape;no input or assertion was silently changed here.
+
+An early passive observer initScript had1 pageerror for relative module resolution on the initial document.
+The observer subsequently DID attach on the actual app and captured the exact cache/subscription chronology below.
+This is an instrumentation error,not a product error. Product methods were not wrapped/replaced;only event listeners
+and read-only queries were added. No refresh/render invocation,manual card insertion,cache mutation,new seeds,
+fake media events/health,extra mirror or product change. Existing earlier driver interventions remain preserved in
+[second-pass history](playback-qa-2-second-pass.md).
+
+All owned browser/context/app+relay servers closed16:06:51.787Z,explicit RELEASE16:07:45Z;temporary dependency
+symlink removed. Preview3000 and other processes untouched. No login/navigation/Profile/Upload/remaining viewport
+checks were executed. Full core/mobile baseline is blocked,not done. QA will resume original assertions only after
+client7 durable landing,integrated preview rebuild and dispatch browser clearance.
