-# 025-squirrel
+# Squirrel Census
 Day 25 of Udemy's *100 Days of Code: The Complete Python Pro Bootcamp*: count the
 squirrels of the 2018 Central Park Squirrel Census by primary fur colour (gray,
 cinnamon, black) and export the counts to `squirrel_count.csv`. Python 3.13 or
 later, no runtime dependencies, with tests and source documentation.
 ![Program run][img-run]
 ## Requirements
 - Python 3.13 or later (`python --version` on Windows, `python3 --version` on Linux and macOS).
 - `venv`, which ships with Python (on Debian: the `python3-venv` package).
 - The 2018 census file. It is already in the repository under `data/`.
 - Optional: [Doxygen][doxygen] 1.9 or later, only to build the source documentation.
 There are no runtime dependencies: the program uses only the Python standard library
 ([ADR-0001][adr-0001]). `pytest` is needed only to run the tests.
 ## Set up
 Create a local virtual environment named `.venv` in the project folder, upgrade `pip`
 and install the project with its development tools (pytest, ruff, mypy, yamllint, actionlint).
 ### Windows powershell
 ```powershell
 python -m venv .venv
 .\.venv\Scripts\Activate.ps1
 python -m pip install --upgrade pip
 python -m pip install -e ".[dev]"
 ```
 If PowerShell refuses to run the activation script, allow it for the current session:
 `Set-ExecutionPolicy -Scope Process -ExecutionPolicy RemoteSigned`.
 ### Linux debian
 ```bash
 sudo apt install python3 python3-venv
 python3 -m venv .venv
 source .venv/bin/activate
 python -m pip install --upgrade pip
 python -m pip install -e ".[dev]"
 ```
 ### MacOS
 ```bash
 python3 -m venv .venv
 source .venv/bin/activate
 python -m pip install --upgrade pip
 python -m pip install -e ".[dev]"
 ```
 On macOS, Python 3.13 can be installed with `brew install python@3.13`.
 ## Run
 With the virtual environment active, run from the project folder:
 ```bash
 python -m squirrel
 ```
 The program reads `data/2018_Central_Park_Squirrel_Census_-_Squirrel_Data.csv`, prints
 the colour counts and writes `squirrel_count.csv`:
 ```text
 Gray: 2473
 Cinnamon: 392
 Black: 103
 ```
 Use other files by passing them as arguments, `python -m squirrel <census file> <summary file>`.
 If the census file does not exist the program prints a message and exits with status 2.
 ## Run the tests
 ```bash
 python -m pytest
 ```
 ![Test run][img-tests]
 The tests use small fixture rows; one test also checks the real 2018 census file when
 it is present.
 ## Continuous integration
 The workflow [`.gitea/workflows/ci.yml`][ci] runs for every push to `main` and for every
 pull request. It sets up Python 3.13, creates a `.venv`, upgrades `pip`, installs the
 project with `.[dev]`, lints the YAML and workflow files with `yamllint` and
 `actionlint`, and runs `python -m pytest`. It uses `github.*` contexts only, so
 it also runs on GitHub Actions.
 ## Build the source documentation
 The source is documented with Doxygen comments and configured by [`Doxyfile`][doxyfile].
 ```bash
 doxygen Doxyfile
 ```
 Open `docs/doxygen/html/index.html` in a browser. The output folder is ignored by git.
 ## Project layout
 ```text

 The repository also has a wiki in English, Danish and Bahasa Malaysia.

 ## Context
 The day 25 lecture reads the census with `pandas.read_csv`, filters rows by fur colour and builds a DataFrame for the export. The Business Case sets a success criterion of zero third-party runtime packages ([BC-001], criterion 3), and stakeholder S03 wants a repository with no runtime dependencies ([SA-001]). Stakeholder S02 wants the function names of the assignment.
 Options evaluated:
 1. **Pandas** — closest to the lecture; adds a large runtime dependency (with NumPy) that every visitor must install.
 2. **Standard library** — the `csv` module to read and write and `collections.Counter` to count; no runtime dependency, a few more lines than Pandas.
 3. **Pandas as an optional extra** — two code paths for one result; more code to test and explain.
 ## Decision
 Use the standard library (`csv` and `collections.Counter`) for reading, counting and writing, and keep the lecture's step names (`read_csv`, `count_by_fur_color`, `build_summary`, `write_csv`) as public function names.
 ## Consequences
 **Positive:**
 - The project has no runtime dependency; `pip install .` installs only the package ([BC-001] criterion 3).
 - Setup is the same on Windows PowerShell, Linux Debian and macOS, with no compiled wheels.
 - The code is short enough to read in one sitting (S02).
 **Negative:**
 - The code differs from the lecture's Pandas calls, so a participant comparing line by line sees different statements.
 - A later assignment that needs DataFrame features must introduce Pandas then.
 ## Affected Artifacts
 - [BC-001] — meets success criterion 3 and mitigates the Pandas risk.
 - [SA-001] — resolves the conflict between S01's lecture and S03's expectation.
 - [MIL-002] — the tasks "Read the census file" to "Add the command line entry point" implement it.

 ## Artifact Under Review
 - Instance reviewed: [PY-MIL-002]
 - Checklist used: [QC-PY-001]
 - Scope: full review of src/squirrel/census.py, cli.py, __main__.py, constants.py and tests/
 - Language and domain: n/a
 - Language reviewer: none (the stand-in reviewer reads English and the `it` domain)
 - Mode: autonomous, not independent (reviewer: AI as stand-in for S01)
 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | Packages, modules, functions, variables, classes and constants follow PEP 8 casing (`snake_case`, `PascalCase`, `UPPER_SNAKE`) (Mandatory) | Pass | Modules, functions and constants use snake_case and UPPER_SNAKE; helper `_build_parser` has one leading underscore. |
 | 2 | Names state purpose in the domain's language; no unexplained abbreviations, no single-letter names outside tiny scopes (Mandatory) | Pass | Names state purpose (`count_by_fur_color`, `write_csv`); the lecture step names are kept (ADR-0001). |
 | 3 | Code is produced by the project's formatter and passes its linter with no unexplained suppressions (Mandatory) | Pass | `ruff check` and `ruff format --check` (0.17.0) pass with no suppressions. |
 | 4 | Every function and method signature is type-annotated, including `-> None` (Mandatory) | Pass | Every function is annotated including `-> None`; `mypy --strict` passes on 10 files. |
 | 5 | No bare `except:`, no swallowed exceptions; specific exceptions are raised and the cause is kept (`raise ... from`) (Mandatory) | Pass | No exception handling; a missing file is checked with `is_file()` and reported with exit status 2. |
 | 6 | No mutable default arguments and no shadowed builtins (Mandatory) | Pass | The only default argument is the immutable tuple `FUR_COLORS`; no builtin is shadowed. |
 | 7 | Files, locks and connections are managed with context managers (Mandatory) | Pass | Files are opened with `with path.open(...)`. |
 | 8 | Public modules, classes and functions have docstrings that say what, not how (Optional) | Pass | Public modules and functions have Doxygen blocks and docstrings. |
 | 9 | Logging uses `logging`, not `print`; no secrets or personal data in log output (Mandatory) | Pass | `print` is used only for the CLI output to the participant and the stderr error line, not for logging; no secrets. |
 | 10 | Classes and operations trace to the Design Class Diagram they implement; deviations are recorded (Mandatory) | N-A | No class is defined and no Design Class Diagram exists; operations trace to [SSD-001] (`countByFurColor`). |
 | 11 | Tests exist for new behaviour, are named for the behaviour, and do not depend on order or the network (Mandatory) | Pass | 20 tests: unit tests per function, CLI tests, a real-census test and an imports test; none depends on order or network. |
 | 12 | Type checker runs in strict mode without errors; `Any` is justified in a comment (Optional) | Pass | `mypy 2.4.0 --strict` reports no issues. |
 | 13 | Dependencies are declared and pinned in the project's dependency file, none unused (Optional) | Pass | No runtime dependency; dev tools pinned in `pyproject.toml`. |
 | 14 | Each piece of knowledge (a business rule, constant, format, validation or query) is defined in one place; code is merged only where it expresses the same knowledge, not where it merely looks alike (Mandatory) | Pass | All literals live in `constants.py`; each step is defined once. |
 | 15 | Imports point inward: business-rule modules import no framework, database, UI or delivery-mechanism code, and there are no import cycles (Mandatory) | Pass | `census.py` imports only the standard library and constants; `cli.py` imports `census`; no cycle. |
 | 16 | SOLID holds: a class or module has one reason to change; new behaviour is added by extension, not by editing a type test in several places; subclasses honour the contract of their base; protocols are narrow; high-level code depends on protocols or abstract types and receives its implementations (Mandatory) | Pass | `census.py` holds four single-purpose functions; the CLI only wires them. |
 ## Overall Verdict
 Go — all Mandatory criteria pass; criterion 10 is not applicable because no class exists.

 # RC Review of ci.yml, delta re-review of criterion 22

 ## Artifact Under Review
 - Instance reviewed: [WF-MIL-001]
 - Checklist used: [QC-WF-001]
 - Scope: delta re-review of criterion 22 of QC-WF-001; reason: the condition of RC-010 (run 1012 queued); earlier record RC-010
 - Language and domain: n/a
 - Language reviewer: none (the stand-in reviewer reads English and the `it` domain)
 - Mode: autonomous, not independent (reviewer: AI as stand-in for S01)
 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 22 | Every workflow feature used is verified on the instance that runs it, and the host and version are recorded; a feature the target hosts differ on is noted in the header (Mandatory) | Pass | Gitea 1.27.3, runner labels ubuntu-latest. `ci.yml` completed with success on the instance: pull_request runs 1037, 1040 and 1043, and the push run 1044 on main (commit c4e88c6). Header states the host and that only github.* contexts are used. |
 ## Overall Verdict
 Go — criterion 22, the only open Mandatory criterion of RC-010, now passes; the other rows of RC-010 still hold, so the workflow is Go. Closes the condition of RC-010.

 | 2 | Explicit Go/No-Go criteria are stated for each gate (Mandatory) | Pass | Go / No-Go criteria unchanged and still objectively checkable; the new test runs under criterion 3 (pytest exits 0). |
 ## Language and Domain Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | The Metadata table has a `Language` row and a `Domain` row, and neither is a placeholder (Mandatory) | Pass | Unchanged. |
 | 2 | `Language` is a BCP 47 code and `Domain` is a value from the registry's domain list (Mandatory) | Pass | Unchanged. |
 | 6 | Metadata keys, section headings, IDs and statuses are in English (Mandatory) | Pass | Keys, headings and statuses are English. |
 | 7 | No translated twin (`<name>.<language>.md`) exists beside the document (Mandatory) | Pass | No translated twin. |
 | 8 | A change of language or domain since the previous accepted version has a Version History row and was reviewed again (Mandatory) | Pass | Language unchanged. |
 ## Overall Verdict
 Go — one task row was added at the request of S01 in chat; the gate criteria and deliverable are unchanged.

 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | Packages, modules, functions, variables, classes and constants follow PEP 8 casing (`snake_case`, `PascalCase`, `UPPER_SNAKE`) (Mandatory) | Pass | Functions, constants (`MAX_RUN_LINES`) and class (`UniqueKeyLoader`) follow PEP 8 casing. |
 | 2 | Names state purpose in the domain's language; no unexplained abbreviations, no single-letter names outside tiny scopes (Mandatory) | Pass | Names state purpose (`exceeds_line_limit`, `load_workflow`). |
 | 3 | Code is produced by the project's formatter and passes its linter with no unexplained suppressions (Mandatory) | Pass | `ruff check` and `ruff format --check` pass with no suppressions. |
 | 4 | Every function and method signature is type-annotated, including `-> None` (Mandatory) | Pass | Every function is annotated; `mypy --strict` passes on 11 files; `Any` is justified by a comment. |
 | 5 | No bare `except:`, no swallowed exceptions; specific exceptions are raised and the cause is kept (`raise ... from`) (Mandatory) | Pass | The duplicate-key loader raises `ValueError` with the key named; no bare except. |
 | 6 | No mutable default arguments and no shadowed builtins (Mandatory) | Pass | No mutable defaults; no builtins shadowed. |
 | 7 | Files, locks and connections are managed with context managers (Mandatory) | Pass | The workflow file is read through `pathlib` and the YAML loader, which close the file. |
 | 8 | Public modules, classes and functions have docstrings that say what, not how (Optional) | Pass | Helpers and tests have docstrings. |
 | 9 | Logging uses `logging`, not `print`; no secrets or personal data in log output (Mandatory) | Pass | No print and no logging; no secrets. |
 | 10 | Classes and operations trace to the Design Class Diagram they implement; deviations are recorded (Mandatory) | N-A | Test code; no class or operation of a design class diagram. |
 | 11 | Tests exist for new behaviour, are named for the behaviour, and do not depend on order or the network (Mandatory) | Pass | 14 tests, one behaviour each, plus a negative self-test of the line limit; no order or network dependence. |
 | 12 | Type checker runs in strict mode without errors; `Any` is justified in a comment (Optional) | Pass | `mypy --strict` passes; `Any` is commented. |
 | 13 | Dependencies are declared and pinned in the project's dependency file, none unused (Optional) | Pass | `pyyaml` and `types-PyYAML` are dev dependencies pinned exactly; no runtime dependency added. |
 | 14 | Each piece of knowledge (a business rule, constant, format, validation or query) is defined in one place; code is merged only where it expresses the same knowledge, not where it merely looks alike (Mandatory) | Pass | The line limit is the single constant `MAX_RUN_LINES`, matching the rule in the YAML convention. |
 | 15 | Imports point inward: business-rule modules import no framework, database, UI or delivery-mechanism code, and there are no import cycles (Mandatory) | Pass | The test imports the standard library and `yaml`; it imports no application code. |
 | 16 | SOLID holds: a class or module has one reason to change; new behaviour is added by extension, not by editing a type test in several places; subclasses honour the contract of their base; protocols are narrow; high-level code depends on protocols or abstract types and receives its implementations (Mandatory) | Pass | One module of small single-purpose helpers and tests. |
 ## Overall Verdict
 Go — all Mandatory criteria pass; criterion 10 is not applicable.

 ## Overall Verdict
 Go — criterion 24 (Optional) now passes; the other rows of RC-010 and RC-025 still hold. Closes the second action item of RC-010.

 | 3 | Passes `yamllint` (or the project's YAML linter) with its configuration committed next to the code and no unexplained `disable` comments (Mandatory) | Pass | `yamllint 1.38.0` with `.yamllint.yml` runs in CI on `.gitea` and `.yamllint.yml`; no errors. `new-lines` is disabled with a comment because git normalises line endings. |
 | 7 | Embedded program text (shell, Python, SQL, `jq`, and so on) in a value is at most five lines; a longer one is moved to a file of its own, in its own language, and the YAML calls it (Mandatory) | Pass | The two new `run:` blocks have one line each; the longest block is still 3 lines. |
 | 10 | The file validates against the schema of the consuming tool where one exists, and the schema or tool version is stated (Optional) | Pass | `actionlint` validates the workflow schema in CI. |
 | 15 | A change is exercised by a check that runs without the real target: a parse and schema test, or a dry run of the consuming tool (Optional) | Pass | yamllint and actionlint now run on every push and pull request without the real target. |

 | 5 | Every job and step has a descriptive `name`, unique within its job (Mandatory) | Pass | The new steps are named "Lint the YAML files" and "Lint the workflow files"; step names stay unique. |
 | 6 | The file passes `actionlint` (or the project's workflow validation test) and the tool version is stated (Mandatory) | Pass | `actionlint 1.7.12` runs in CI against `.gitea/workflows/*.yml` and passes. |
 | 17 | Tools and dependencies are installed at pinned versions; a version is a workflow input with a default or a value in one place (Mandatory) | Pass | `yamllint==1.38.0` and `actionlint-py==1.7.12.25` are exact pins in the dev extra of `pyproject.toml`. |
 | 20 | A `run:` block is within the limit on embedded program text of criterion 7 of [QC-YML-001]; a longer script is a file (`tools/`, or a shared repository fetched at a pinned ref) that the step calls with one command, and the workflow passes its settings through `env:` (Mandatory) | Pass | Each new `run:` block is one line. |
 | 22 | Every workflow feature used is verified on the instance that runs it, and the host and version are recorded; a feature the target hosts differ on is noted in the header (Mandatory) | Pass | The changed workflow completed with success on Gitea 1.27.3: run 1087 on pull request #39. |
 | 24 | A static test of the repository's workflows exists and runs on every pull request: valid YAML, required keys, explicit permissions and runner, no inline script above the limit (Optional) | Pass | `tests/test_workflow.py` still passes (33 tests) with the new steps. |

 | 1 | A concrete deliverable is defined for every gate (Mandatory) | Pass | Deliverable unchanged; the new task extends the CI workflow already in the deliverable. |
 | 2 | Explicit Go/No-Go criteria are stated for each gate (Mandatory) | Pass | Go / No-Go criteria unchanged and objectively checkable; the lint steps run in the same CI run as criterion 3. |
 ## Language and Domain Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | The Metadata table has a `Language` row and a `Domain` row, and neither is a placeholder (Mandatory) | Pass | Unchanged. |
 | 2 | `Language` is a BCP 47 code and `Domain` is a value from the registry's domain list (Mandatory) | Pass | Unchanged. |

 | 8 | A change of language or domain since the previous accepted version has a Version History row and was reviewed again (Mandatory) | Pass | Language unchanged. |
 ## Overall Verdict
 Go — one task row was added at the request of S01 in chat, after the work was done and reviewed in RC-031 and RC-032; the gate criteria and deliverable are unchanged. The remaining criteria 3 to 6 of QC-MIL-001 and 3, 4, 5, 9, 10 of QC-LANG-001 were passed in RC-003 and are unaffected by a new task row.

 ## Language and Domain Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | The Metadata table has a `Language` row and a `Domain` row, and neither is a placeholder (Mandatory) | Pass | Unchanged. |
 | 2 | `Language` is a BCP 47 code and `Domain` is a value from the registry's domain list (Mandatory) | Pass | Unchanged. |
 | 6 | Metadata keys, section headings, IDs and statuses are in English (Mandatory) | Pass | Keys, headings and statuses are English. |
 | 7 | No translated twin (`<name>.<language>.md`) exists beside the document (Mandatory) | Pass | No translated twin. |
 | 8 | A change of language or domain since the previous accepted version has a Version History row and was reviewed again (Mandatory) | Pass | Language unchanged. |
 ## Overall Verdict
 Go — only a missing link definition and a CrossReference entry were added; the other criteria were passed in the earlier records (RC-006, RC-023, RC-027) and are unaffected.

 ## Source Use Case
 Count squirrels by fur colour ([UC-001]) — scenario: main success scenario. The alternate flow 1a (census file missing) is the second diagram; flow 2a has no system message of its own.
 ## Diagram
 ```plantuml
@startuml
 actor Participant as A
 participant ":System" as S
 A -> S : countByFurColor(censusFile, summaryFile)
 S --> A : summary
@enduml
 ```
 ```plantuml
@startuml
 actor Participant as A
 participant ":System" as S
 A -> S : countByFurColor(censusFile, summaryFile)
 S --> A : censusFileMissing
@enduml
 ```
 ## System Operations
 | Step | Message | Parameters | Return | Use case step |
 | --- | --- | --- | --- | --- |
 | 1 | countByFurColor | censusFile, summaryFile | summary (colour count of each fur colour) | 1 (input), 2 (count), 3 (write), 4 (shown to the participant) |
 | 1a | countByFurColor | censusFile, summaryFile | censusFileMissing | 1a |
 Steps 2 to 4 of the use case are the work of the system inside one operation: the system receives one message and returns one result, so one message covers steps 1 to 4.
 ## Lifecycle Notes
 The system instance lives for one run of the program; nothing is kept between runs.

 **Format:** Fully Dressed
 - **Scope:** Squirrel census program
 - **Level:** user-goal
 - **Primary Actor:** Participant (as named in [UCD-001])
 - **Stakeholders and Interests:**
  - S01 — a correct summary that matches the dataset and the assignment
  - S02 — a result that is easy to reproduce from the README
  - S03 — a program with no runtime dependencies
 - **Preconditions:** The participant has the census file.
 - **Postconditions (success guarantee):** The summary file exists and holds the colour count of Gray, Cinnamon and Black; the participant has seen the counts.
 ### Main Success Scenario
 1. The participant supplies the census file and the name of the summary file.
 2. The system counts the squirrel sightings of each fur colour.
 3. The system writes the summary to the summary file.
 4. The system shows the participant the colour count of each fur colour.
 ### Extensions / Alternative Flows
 - 1a. The census file does not exist: the system tells the participant that the file is missing and ends without writing a summary.
 - 2a. A squirrel sighting has no fur colour: the system leaves it out of every colour count.
 ### Special Requirements / Business Rules
 - Step 2: only the fur colours Gray, Cinnamon and Black are counted; a colour count is the number of sightings with that exact fur colour.
 - Step 3: the summary has one row per counted fur colour, in the order Gray, Cinnamon, Black.
 ### Open Issues
 None.

 ## Purpose and Scope
 Covers the epic delivered by [MIL-002]: the participant counts squirrels by fur colour. Objective 1 of [BC-001].
 ## Story List
 ### US-001.01 — Count squirrels by fur colour
 **As a** Participant, **I want** to count the squirrels of each fur colour in the census file, **so that** I get a summary file with the number of gray, cinnamon and black squirrels.
 **Acceptance Criteria**
 - Given a census file with squirrel sightings, when the participant counts by fur colour, then the summary lists Gray, Cinnamon and Black with the number of sightings of each.
 - Given the 2018 census file, when the participant counts by fur colour, then the summary shows Gray 2473, Cinnamon 392 and Black 103.
 - Given a census file with a sighting that has no fur colour, when the participant counts, then that sighting is in no colour count.
 - Given a census file that does not exist, when the participant counts, then the participant is told that the file is missing and no summary is written.
 | Traces to | Size | INVEST exceptions |
 | --- | --- | --- |
 | [UC-001], [MIL-002] | fits one iteration | none |
 ## INVEST Check
 Independent (the only story), Negotiable (file names are defaults), Valuable (delivers the assignment result), Estimable, Small (one iteration), Testable (the criteria are checkable with fixture rows and the 2018 census file). No exceptions.

 # Beskrivelse
 ## Hvad programmet gør
 Programmet følger lektionens trin:
 1. `read_csv` læser optællingsfilen.
 2. `count_by_fur_color` tæller observationerne af Gray, Cinnamon og Black.
 3. `build_summary` gør tallene til rækkerne i en opsummering.
 4. `write_csv` skriver opsummeringen til `squirrel_count.csv`.
 På optællingsfilen fra 2018 er resultatet Gray 2473, Cinnamon 392 og Black 103. Observationer uden pelsfarve tælles ikke med i nogen af dem.
 ## Hvorfor ikke Pandas
 Lektionen bruger Pandas. Dette projekt bruger kun Pythons standardbibliotek (`csv` og `collections.Counter`), så der ikke er noget at installere for at køre det. Beslutningen er beskrevet som ADR-0001 i repositoryet.

 # Description
 ## What it does
 The program follows the steps of the lecture:
 1. `read_csv` reads the census file.
 2. `count_by_fur_color` counts the sightings of Gray, Cinnamon and Black.
 3. `build_summary` turns the counts into the rows of a summary.
 4. `write_csv` writes the summary to `squirrel_count.csv`.
 On the 2018 census file the result is Gray 2473, Cinnamon 392 and Black 103. Sightings without a fur colour are counted in none of them.
 ## Why no Pandas
 The lecture uses Pandas. This project uses only the Python standard library (`csv` and `collections.Counter`) so that there is nothing to install to run it. The decision is recorded as ADR-0001 in the repository.
 ## Layout
 | Path | Content |

 | `src/squirrel/constants.py` | Every literal, defined once |
 | `tests/` | The pytest tests |
 | `docs/` | Business case, plan, models, review records |
 ## Quality
 Every document and every piece of code was reviewed against the checklists of the SQA and QC framework, in autonomous mode: the reviewer is an AI stand-in, so the reviews are not independent.

 # Penerangan
 ## Apa yang dilakukan program
 Program mengikut langkah dalam pelajaran:
 1. `read_csv` membaca fail banci.
 2. `count_by_fur_color` mengira pemerhatian Gray, Cinnamon dan Black.
 3. `build_summary` menukar kiraan kepada baris ringkasan.
 4. `write_csv` menulis ringkasan ke `squirrel_count.csv`.
 Pada fail banci 2018 hasilnya ialah Gray 2473, Cinnamon 392 dan Black 103. Pemerhatian tanpa warna bulu tidak dikira dalam mana-mana satu.
 ## Mengapa tidak menggunakan Pandas
 Pelajaran menggunakan Pandas. Projek ini hanya menggunakan pustaka standard Python (`csv` dan `collections.Counter`) supaya tiada apa-apa untuk dipasang bagi menjalankannya. Keputusan itu direkodkan sebagai ADR-0001 dalam repositori.
 ## Susun atur
 | Laluan | Kandungan |

 | `tests/` | Ujian pytest |
 | `docs/` | Kes perniagaan, pelan, model, rekod semakan |
 ## Kualiti
 Setiap dokumen dan kod disemak berdasarkan senarai semak rangka kerja SQA dan QC dalam mod autonomi: penyemak ialah pengganti AI, jadi semakan itu tidak bebas.

 # Brug
 ## Kør programmet
 Med det virtuelle miljø aktivt, fra projektmappen:
 ```bash
 python -m squirrel
 ```
 Programmet læser `data/2018_Central_Park_Squirrel_Census_-_Squirrel_Data.csv`, skriver tallene for hver pelsfarve og gemmer `squirrel_count.csv`.
 ![Programkørsel](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/025-squirrel/raw/branch/main/docs/images/run.png)
 Brug andre filer med `python -m squirrel <optællingsfil> <opsummeringsfil>`. Findes optællingsfilen ikke, skriver programmet `Census file not found` og afslutter med status 2.
 ## Kør testene
 ```bash
 python -m pytest
 ```

 # Usage
 ## Run the program
 With the virtual environment active, from the project folder:
 ```bash
 python -m squirrel
 ```
 The program reads `data/2018_Central_Park_Squirrel_Census_-_Squirrel_Data.csv`, prints the colour counts and writes `squirrel_count.csv`.
 ![Program run](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/025-squirrel/raw/branch/main/docs/images/run.png)
 Use other files with `python -m squirrel <census file> <summary file>`. If the census file does not exist, the program prints `Census file not found` and exits with status 2.
 ## Run the tests
 ```bash
 python -m pytest
 ```
