```
+## Dumpstate philosophy: exec not link
+
+Never link code directly into dumpstate. Dumpstate should execute many
+binaries and collect the results. In general, code should fail hard fail fast,
+but dumpstate is the last to solve many Android bugs. Oftentimes, failures
+in core Android infrastructure or tools are issues that cause problems in
+bugreport directly, so bugreport should not rely on these tools working.
+We want dumpstate to have as minimal of code loaded in process so that
+only that core subset needs to be bugfree for bugreport to work. Even if
+many pieces of Android break, that should not prevent dumpstate from
+working.
+

+ * apps with inconsistent or low workload to take any useful action but simply monitoring. And to
+ * avoid oscillation it's not recommended to adjust workload too frequent (on each polling request)
+ * or too aggressively. As the headroom calculation is more based on reflecting past history usage
+ * than predicting future capacity. Take game as an example, if the API returns CPU headroom of 0 in
+ * one scenario (especially if it's constant across multiple calls), or some value significantly
+ * smaller than other scenarios, then it can reason that the recent performance result is more CPU
+ * bottlenecked. Then reducing the CPU workload intensity can help reserve some headroom to handle
+ * the load variance better, which can result in less frame drops or smooth FPS value. On the other
+ * hand, if the API returns large CPU headroom constantly, the app can be more confident to increase
+ * the workload and expect higher possibility of device meeting its performance expectation.
+ * App can also use thermal APIs to read the current thermal status and headroom first, then poll
+ * the CPU and GPU headroom if the device is (about to) getting thermal throttled. If the CPU/GPU
+ * headrooms provide enough significance such as one valued at 0 while the other at 100, then it can
+ * be used to infer that reducing CPU workload could be more efficient to cool down the device.

+
+namespace android::ftl {
+
+// An RAII wrapper that invokes a function object as a finalizer when destroyed.
+//
+// The function object must take no arguments, and must return void. If the function object needs
+// any context for the call, it must store it itself, for example with a lambda capture.
+//
+// The stored function object will be called once (unless canceled via the `cancel()` member
+// function) at the first of:
+//
+// - The Finalizer instance is destroyed.
+// - `operator()` is used to invoke the contained function.
+// - The Finalizer instance is move-assigned a new value. The function being replaced will be
+// invoked, and the replacement will be stored to be called later.
+//
+// The intent with this class is to keep cleanup code next to the code that requires that
+// cleanup be performed.
+//
+// bool read_file(std::string filename) {
+// FILE* f = fopen(filename.c_str(), "rb");
+// if (f == nullptr) return false;
+// const auto cleanup = ftl::Finalizer([f]() { fclose(f); });
+// // fread(...), etc
+// return true;
+// }
+//
+// The `FinalFunction` template argument to Finalizer<FinalFunction> allows a polymorphic function
+// type for storing the finalization function, such as `std::function` or `ftl::Function`.
+//
+// For convenience, this header defines a few useful aliases for using those types.
+//
+// - `FinalizerStd`, an alias for `Finalizer<std::function<void()>>`
+// - `FinalizerFtl`, an alias for `Finalizer<ftl::Function<void()>>`
+// - `FinalizerFtl1`, an alias for `Finalizer<ftl::Function<void(), 1>>`
+// - `FinalizerFtl2`, an alias for `Finalizer<ftl::Function<void(), 2>>`
+// - `FinalizerFtl3`, an alias for `Finalizer<ftl::Function<void(), 3>>`
+//
+// Clients of this header are free to define other aliases they need.
+//
+// A Finalizer that uses a polymorphic function type can be returned from a function call and/or
+// stored as member data (to be destroyed along with the containing class).
+//
+// auto register(Observer* observer) -> ftl::FinalizerStd<void()> {
+// const auto id = observers.add(observer);
+// return ftl::Finalizer([id]() { observers.remove(id); });
+// }
+//
+// {
+// const auto _ = register(observer);
+// // do the things that required the registered observer.
+// }
+// // the observer is removed.
+//
+// Cautions:
+//
+// 1. When a Finalizer is stored as member data, you will almost certainly want that cleanup to
+// happen first, before the rest of the other member data is destroyed. For safety you should
+// assume that the finalization function will access that data directly or indirectly.
+//
+// This means that Finalizers should be defined last, after all other normal member data in a
+// class.
+//
+// class MyClass {
+// public:
+// bool initialize() {
+// ready_ = true;
+// cleanup_ = ftl::Finalizer([this]() { ready_ = false; });
+// return true;
+// }
+//
+// bool ready_ = false;
+//
+// // Finalizers should be last so other class members can be accessed before being
+// // destroyed.
+// ftl::FinalizerStd<void()> cleanup_;
+// };
+//
+// 2. Care must be taken to use `ftl::Finalizer()` when constructing locally from a lambda. If you
+// forget to do so, you are just creating a lambda that won't be automatically invoked!
+//
+// const auto bad = [&counter](){ ++counter; }; // Just a lambda instance
+// const auto good = ftl::Finalizer([&counter](){ ++counter; });

+ // tiled GPUs, so they don't actually use GPU memory. However, in Vulkan there are scenarios

+ // Therefore, we set the full maxResourceBytes budget on the Recorder. However, in the rare
+ // chance that the devcies does allocate real memory we don't want to immediately kill device
+ // performance by constantly trashing allocations on the Context. Thus we set the Context's
+ // budget to be 50% of the total budget to make sure we allow the MSAA or Stencil buffers to be
