Breakdown of growth, maintenance, and fixes effort over time.
Bugs introduced vs. fixed over time.
Reclassifies engineering effort based on bug attribution. Commits that introduced bugs are retrospectively counted as poor investments.
Investment Quality reclassifies engineering effort based on bug attribution data. Commits identified as buggy origins (those that introduced bugs later fixed by someone) have their grow and maintenance time moved into the Wasted Time category. Their waste (fix commits) remains counted as productive. All other commits retain their standard classification: grow is productive, maintenance is maintenance, and waste (fixes) is productive.
The standard model classifies commits as Growth, Maintenance, or Fixes. Investment Quality adds a quality lens: a commit that introduced a bug is retrospectively counted as a poor investment — the engineering time spent on it was wasted because it ultimately required additional fix work. Fix commits (Fixes in the standard model) are reframed as productive, because fixing bugs is valuable work.

| e0bd528 | This commit implements a **security enhancement** for the **Python Dapr runtime integration** by changing the default behavior of the `allowed_module_prefixes` parameter from `None` to `("semantic_kernel.",)`. This **configuration change** ensures that only step classes within the `semantic_kernel` module prefix are loaded by default, enforcing a **secure-by-default** posture for the experimental Dapr runtime. The core logic for this is updated in `get_step_class_from_qualified_name` within `step_utils.py`, with corresponding parameter updates across `dapr_runtime` classes like `StepActor` and `DaprKernelProcessContext`. Developers using custom step classes outside this prefix will now need to explicitly configure the `allowed_module_prefixes` parameter, impacting how external modules are integrated into **Semantic Kernel** processes. This **refactoring** of default parameters improves the overall security stance of the system. | Mar 24 | 9 | maint |
