 ## 2025-02-15 - Replace Array.from(map.values()).map with a for...of loop
 **Learning:** Using `Array.from(map.values()).map(...)` creates an unnecessary intermediate array which wastes memory allocation and garbage collection time, particularly for frequently re-rendered components handling large collections.
 **Action:** Use a `for...of` loop over `map.values()` to iterate and push mapped elements directly into the final array for O(1) memory and avoiding intermediate array allocations.
+## 2025-02-16 - Hoist static mathematical DOM generation to module-level constants
+**Learning:** Generating decorative elements iteratively (e.g. `Array.from({ length: 84 }).map(...)`) inside a React component's render body causes unnecessary array allocations and garbage collection on every render cycle.
+**Action:** Extract static mathematical DOM generation into module-level constants to avoid O(N) allocation overhead per render.

@@ -104,7 +104,6 @@ Current controlled exceptions:
 - No Python vulnerability exceptions are active. `GHSA-5239-wwwm-4pmq` (`Pygments <2.20.0`) was removed by locking `Pygments` to `2.20.0`; the CI `security-audit` workflow must run `pip-audit --local --strict` against the synced `uv` environment without a targeted ignore for that advisory.
 - Cargo audit warnings for legacy `gtk3` vulnerabilities (e.g. `RUSTSEC-2024-0413`) inherited through Tauri v2 `wry`/`webkit2gtk` integration are explicitly allowed. These are deep framework dependencies with no alternative, so they are documented exceptions and ignored by default.
 - `RUSTSEC-2024-0429` for `glib 0.18.5` is allowed only for the `VariantStrIter` advisory inherited through the Tauri/wry/webkit2gtk/gtk GTK3 stack. A compatible lockfile refresh can move the desktop stack to `tauri 2.11.3`, `wry 0.55.1`, `tao 0.35.3`, `muda 0.19.3`, and related transitive patches, but it still does not move this stack to patched `glib >=0.20.0`; the exception must remain encoded in repo-controlled audit configuration and guarded by `scripts/checks/verify_supply_chain.py`, and it must be removed when upstream drops or patches the chain.
-- `RUSTSEC-2026-0194` and `RUSTSEC-2026-0195` for `quick-xml 0.39.4` are allowed only while the current compatible upstream owner chains still require vulnerable `quick-xml`: `plist 1.9.0` through Tauri, and `wayland-scanner 0.31.10` through Linux `rfd`/Wayland dependencies. `quick-xml >=0.41.0` is patched, but `plist 1.9.0` requires `quick-xml ^0.39.2` and the current `wayland-scanner` release also has no compatible patched path. BandScope does not expose either owner chain as a user-controlled XML ingestion surface; the exception must stay encoded in repo-controlled cargo-audit and OSV configuration, and must be removed once compatible upstream crates publish a patched dependency path.
