 * Fix LAL `layer: auto` mode dropping logs after extractor set the layer. Codegen now propagates `layer "..."` assignments to `LogMetadata.layer` so `FilterSpec.doSink()` sees the script-decided layer.
 * Fix MetricKit histogram percentile metrics being reported at 1000× their true value — the listener now marks its `SampleFamily` with `defaultHistogramBucketUnit(MILLISECONDS)` so MAL's default SECONDS→MS rescale of `le` labels is not applied.
 * Add WeChat and Alipay Mini Program monitoring via the SkyAPM mini-program-monitor SDK (SWIP-12). Two new layers (`WECHAT_MINI_PROGRAM`, `ALIPAY_MINI_PROGRAM`); two new JavaScript componentIds (`WeChat-MiniProgram: 10002`, `AliPay-MiniProgram: 10003`). Service / instance / endpoint entities are produced by MAL + LAL, not trace analysis — mini-programs are client-side (exit-only) so `RPCAnalysisListener` stays unchanged (same pattern as browser and iOS). MAL rules per platform × scope under `otel-rules/miniprogram/` with explicit `.service(...)` / `.endpoint(...)` chains (empty `expSuffix` so endpoint-scope rules aren't overridden), histogram percentile via `.histogram("le", TimeUnit.MILLISECONDS)` to keep ms bucket bounds intact, and request-cpm derived from the histogram `_count` family. LAL `layer: auto` rule produces both layers via `miniprogram.platform` dispatch and emits error-count samples consumed by per-platform log-MAL rules. Per-layer menu entries and service / instance / endpoint dashboards with Trace and Log sub-tabs.
+* Fix: remove `VirtualServiceAnalysisListener`'s dependency on `GenAIAnalyzerModule` if it is disabled.
 * MAL: register `TimeUnit` in `MALCodegenHelper.ENUM_FQCN` so rule YAML can write `.histogram("le", TimeUnit.MILLISECONDS)` for SDKs that emit histogram bucket bounds in ms (default `SECONDS` unit applies a ×1000 rescale that would otherwise inflate stored `le` labels 1000×).
