+# Verification: Community QR replacement
+
+- Date: 2026-11-10
+- Base: `75c7b8b01268637ea1bb52b60f096436c0782988`
+- Scope: root README translations, community image, shared UI where applicable, and engineering records.
+- Result: PASS — scoped local checks; remote merge/publication remains separate.
+
+## Verified source
+
+The maintainer's JPEG is 436 × 434 pixels. Independent ZXing decoding yields the updated DingTalk invitation used by the clickable links. The group name, number and release announcement are unchanged. Preserve the original image bytes; old verification records remain historical.
+
+## Checks
+
+- PASS: `bash scripts/check-repo-health.sh --quiet` and `make hygiene`.
+- PASS: both README paths resolve to the byte-identical JPEG; independent ZXing decoding matches the updated clickable URL. Old PNG references are absent from the current README/UI entries.
+- PASS: group number, release version/date and existing relative Markdown links preserved; `git diff --check`.
+- Image SHA256: `e7951550c99f07e60366801911577ecc29ff81966a7a36a172a10bca39573b39`.
+- No additional runtime tests needed for this asset/link replacement; required remote CI is not bypassed.
+
+## Limits
+
+No runtime/package release or cloud resources; no DingTalk membership action. Remote CI and deployment are verified separately. Template PR303 was already blocked by unavailable pinned LibreOffice dependencies (Issue304); this asset change does not modify that workflow or its dependencies.

+# Decision: Refresh the developer community QR code
+
+Status: proposed
+
+## Problem
+
+The maintainer supplied a replacement DingTalk QR image on November 10 after the initial announcement.
+
+## Decision
+
+Replace the old PNG with the supplied 436 × 434 JPEG unchanged. Update both README image paths and clickable join URLs to the destination decoded from that image. Website shared UI owns the matching footer asset and URL; synchronize it to Registry. Keep the preview announcement, group name and group number unchanged.
+
+## API Design
+
+N/A — this decision does not involve API changes.
+
+## Alternatives considered
+
+Keeping the previous clickable URL would make clicking and scanning use different invitations. Converting or redrawing the supplied image is unnecessary; preserve its original bytes and file type.
+
+## Dependencies
+
+User attachment: https://api.agent.run/api/v1/uploads/up-x2G9-QN8rwuTx_0CKHcNkw.jpg . The shared UI source belongs to https://github.com/Alibaba-Agent-Sandbox/website .
+
+## Test Strategy
+
+Decode the replacement, compare asset bytes, validate bilingual image/link references, run owner document/build checks and inspect the rendered QR. Preserve all required remote CI gates.
+
+## Acceptance criteria
+
+The original replacement image is served, clicking and scanning use the same invitation, old image references are removed from current user-facing entry points, and affected source changes pass required checks before merge. Template PR303 retains its separately tracked CI blocker until resolved.
