I tested this PR and verified the version sync at the merged commit b0c67b73 (v0.2.87 → v0.2.88) across all 8 guarded sources:

• emrg/__init__.py: __version__ = "0.2.88" ✓
• pyproject.toml: version = "0.2.88" ✓
• uv.lock: version = "0.2.88" ✓
• emrg/gui/package.json: "version": "0.2.88" ✓
• emrg/gui/package-lock.json: "version": "0.2.88" in both the root and packages sections ✓ (the source added to the sync guard in emrg: guard package-lock.json in version-sync test (issue #1065) #1066)
• packaging/build-runtime.sh: echo "0.2.88" > "$DIST/version.txt" ✓
• packaging/make-installer.sh: || echo 0.2.88 fallback ✓
• packaging/make-run-installer.sh: || echo 0.2.88 fallback ✓

No leftover 0.2.87 references in the diff. CI: PR-branch Test run 33252318304 success; post-merge master Test run 33257204716 in progress at review time. Build Release will trigger on the v0.2.88 tag push (last 5 runs v0.2.83–v0.2.87 all green).
