-        **Why Heap Allocation Matters:**
-
-        ESP devices run for months with small heaps shared between Wi-Fi, BLE, LWIP, and application code. Over time, repeated allocations of different sizes fragment the heap. Failures happen when the largest contiguous block shrinks, even if total free heap is still large. We have seen field crashes caused by this.
-
-        **Heap allocation after `setup()` should be avoided unless absolutely unavoidable.** Every allocation/deallocation cycle contributes to fragmentation. ESPHome treats runtime heap allocation as a long-term reliability bug, not a performance issue. Helpers that hide allocation (`std::string`, `std::to_string`, string-returning helpers) are being deprecated and replaced with buffer and view based APIs.

            Linear search on small datasets (1-16 elements) is often faster than hashing/tree overhead, but this depends on lookup frequency and access patterns. For frequent lookups in hot code paths, the O(1) vs O(n) complexity difference may still matter even for small datasets. `std::vector` with simple structs is usually fine—it's the heavy containers (`map`, `set`, `unordered_map`) that should be avoided for small datasets unless profiling shows otherwise.

+        5. **Detection:** Look for these patterns in compiler output:

         - Components causing flash size complaints
 
-        Note: Avoiding heap allocation after `setup()` is always required regardless of component type. The prioritization above is about the effort spent on container optimization (e.g., migrating from `std::vector` to `StaticVector`).
+        **When not to optimize:**
+        - Single-use niche components
+        - Code where readability matters more than bytes
+        - Already using appropriate containers
 
     *   **State Management:** Use `CORE.data` for component state that needs to persist during configuration generation. Avoid module-level mutable globals.

-# ESPHome PR Workflow
-
-When creating a pull request for esphome, follow these steps:
-
-## 1. Create Branch from Upstream
-
-Always base your branch on **upstream** (not origin/fork) to ensure you have the latest code:
-
-```bash
-git fetch upstream
-git checkout -b <branch-name> upstream/dev
-```
-
-## 2. Read the PR Template
-
-Before creating a PR, read `.github/PULL_REQUEST_TEMPLATE.md` to understand required fields.
-
-## 3. Create the PR
-
-Use `gh pr create` with the **full template** filled in. Never skip or abbreviate sections.
