User Stories¶

Domains¶

The following domains are derived from the bounded contexts identified in the architecture:

INPUT — Input Parser: reads standard input, parses minefield dimensions and rows, groups them into Field structures, and stops processing when 0 0 is encountered
PROC — Field Processor: computes the number of adjacent mines for every safe cell in a field
OUTPUT — Output Formatter: prints annotated fields to standard output using the required Field #N: headers and blank-line separators

These domains directly map to the bounded contexts defined in the Building Block View (Chapter 5) and are used as the basis for story IDs and traceability.

DDD Building Blocks¶

Architecture reference: Chapter 5 Building Block View, Chapter 12 Glossary

Entities¶

None explicitly identified from the architecture — the system is stateless and processes fields in a single pass with no persistent identity

Aggregates¶

Field — aggregate root grouping rows, cols, and grid; represents one complete minesweeper field and is the consistency boundary passed between all three pipeline components

Value Objects¶

grid (rows of . / *) — immutable sequence of strings representing the raw minefield; defined by its content, not identity
AnnotatedGrid (rows of digits / *) — immutable result of processing; each cell is either * or a digit character

Domain Services¶

Input Parser — stateless service that reads an istream and produces a collection of Field aggregates (Chapter 5 Building Block View)
Field Processor — stateless service that transforms a Field aggregate into an annotated grid (Chapter 5 Building Block View)
Output Formatter — stateless service that serialises annotated fields to an ostream (Chapter 5 Building Block View)

Prioritized Story Inventory¶

Core Stories (Pareto 20%)¶

INPUT-STORY-001 AS A user I WANT the program to parse one or more minefields from standard input SO THAT each field can be processed correctly
PROC-STORY-001 AS A user I WANT every safe cell to be replaced with the correct adjacent mine count SO THAT the annotated minefield is correct
OUTPUT-STORY-001 AS A user I WANT each processed field to be printed in the required kata output format SO THAT the result matches the specification exactly

Supporting Stories (Remaining 80%)¶

INPUT-STORY-002 AS A user I WANT input processing to stop when 0 0 is encountered SO THAT the program terminates according to the kata rules
INPUT-STORY-003 AS A user I WANT multiple fields to be read sequentially from one input stream SO THAT all provided minefields are processed in one run
OUTPUT-STORY-002 AS A user I WANT fields to be numbered as Field #1, Field #2, and so on SO THAT each output block is clearly identified
OUTPUT-STORY-003 AS A user I WANT blank lines to separate printed fields correctly SO THAT the output formatting matches the kata requirements
PROC-STORY-002 AS A developer I WANT the program to compile and run reproducibly as a single C++ binary SO THAT processing logic can be verified consistently

Pareto Prioritization¶

The three core stories represent the minimal viable functionality of the Minesweeper Field Processor kata. They are chosen because:

INPUT-STORY-001 — without parsing, no field can enter the pipeline; it unblocks every other story
PROC-STORY-001 — the central computation; directly delivers the user-visible value of the kata
OUTPUT-STORY-001 — without formatted output, no result is observable; closes the pipeline end-to-end

Together they exercise all three architecture components (Input Parser, Field Processor, Output Formatter) and the full pipeline runtime flow described in Chapter 6. All supporting stories are refinements or edge cases of these three.
