# Technical Document Extraction: Transition Probabilities Heatmap
## 1. Document Overview
This image is a **Heatmap** titled **"Transition Probabilities Heatmap"**. It visualizes the conditional probability of a "Next Action" (x-axis) occurring given a sequence of "Previous 2 Actions" (y-axis). The data represents state transitions in a computational or workflow environment (likely software development or file management).
## 2. Component Isolation

## 5. Key Trends and Observations
### Deterministic Transitions (Probability = 1.00)
* **Start Sequence:** After `<START>, create`, the next action is always `edit` (1.00).
* **End Sequence:** After `rm, submit`, the next action is always `<END>` (1.00).
### High Probability Clusters (Strong Trends)
* **Editing Loops:** If the previous actions were `edit (2x)`, there is a 0.72 probability the next action is `edit` again, suggesting a repetitive task.
* **Navigation Patterns:**
* `open, search_file` is followed by `goto` with a 0.74 probability.
* `python, find_file` is followed by `open` with a 0.70 probability.
* **Execution Patterns:**
* `create, edit` is followed by `python` (0.73), likely indicating a "create-edit-run" cycle.
* `python, edit` is followed by `python` (0.57), indicating a "fix-and-run" cycle.
### Low Probability / Sparse Areas
* The `<END>` action is almost never reached except through the `rm, submit` sequence.
* The `pytest` action has extremely low transition probabilities across all observed histories (mostly 0.00 or 0.01), suggesting it is a rare or specific terminal action not well-captured by these common histories.
* The `exit_cost` and `scroll_up` actions also show very low engagement across the board.
