+# Continuous integration for the NATO alphabet project.
+#
+# Purpose:  run the pytest suite on Python 3.13 so a change is known to work
+#           before it is merged (BC-001 objective O3, success criterion 2).
+# Triggers: a push to main or to a milestone branch, and every pull request
+#           that touches source, tests, project configuration or this file.
+# Inputs:   none.
+# Secrets:  none. The job reads the repository only.
+# Changes:  nothing outside the repository.
+# Decision: MIL-001 task "Add the CI workflow".
+# Host:     Gitea Actions (act_runner); the same file runs on GitHub Actions.
+#           The runner must offer the label ubuntu-latest.

+# ADR-0001 Read the NATO data with the standard library csv module
+
+## Metadata
+| Key | Value |

+| ID | ADR-0001 |

+## Version History
+| Date | Status | Author | Reviewer | Change | Commit |
+| --- | --- | --- | --- | --- | --- |
+| 2026-10-13 | Accepted | Jens Tirsvad Nielsen | AI as stand-in for S01 | Initial version, reviewed in RC-006 | [32a8b84] |
+
+Allowed Status values: `Proposed`, `Accepted`, `Rejected`, `Deprecated`, `Superseded by ADR-NNNN`.
+
+---
+
+## Context
+
+The lecture reads the NATO alphabet file into a Pandas DataFrame and builds the dictionary with `iterrows`. The file has 26 rows and two columns. S01 follows the lecture, but S03 wants a repository with no runtime dependencies, and [BC-001] objective O5 and constraint "no runtime dependencies unless needed" say the same.
+
+Options evaluated:
+
+1. Pandas, as in the lecture: matches the course, but adds a large runtime dependency for a 26-row table.
+2. Polars: smaller than Pandas, still a runtime dependency that the task does not need.
+3. The standard library `csv` module: no dependency, and the dictionary comprehension that the assignment teaches works unchanged on the rows of `csv.DictReader`.
+
+## Decision
+
+Read the NATO alphabet with the standard library `csv` module (`csv.DictReader`) and build the letter-to-code-word dictionary with a dictionary comprehension. The project declares no runtime dependencies.
+
+## Consequences
+
+**Positive:**
+
+- No runtime dependency to install or keep secure; S03 sees an empty dependency list.
+- Faster start and a smaller environment for S02.
+- The comprehension taught in the lecture is still used.
+
+**Negative:**
+
+- The code differs from the lecture's Pandas code, so S02 comparing line by line sees a difference.
+- A later day that needs Pandas has to add it explicitly.
+
+## Affected Artifacts
+
+- [BC-001] — meets objective O5 and the constraint on runtime dependencies.
+- [SA-001] — resolves the conflict between S01 and S03 listed there.

+
+## Context
+
+The journey of the framework offers analysis documents beyond the baseline: KPI definitions, a Business Model Canvas, a BPMN process model and a riskiest-assumption test. The project is a single-evening course exercise with six measurable success criteria already in [BC-001], no commercial model, no business process and no costly belief to test.
+
+Options evaluated:
+
+1. Write all four documents: complete, but each needs a review and adds no decision that the Business Case does not already hold.
+2. Write only the KPI definitions: the success criteria would be restated in another file.
+3. Skip all four and record the reason here.
+
+## Decision
+
+Skip the KPI definitions, the Business Model Canvas, the BPMN process model and the riskiest-assumption test. The Business Case's Success Criteria table carries the measures, and the baseline documents (Business Case, Stakeholder Analysis, Project Plan, milestones) are not skipped.
+
+## Consequences
+
+**Positive:**
+
+- Less documentation to keep consistent for a small project.
+- The success criteria are stated once, in one place.
+
+**Negative:**
+
+- A reader who expects a KPI document finds the measures in the Business Case instead.
+- If the project grows (a package published, more users), the skipped documents must be written then.
+
+## Affected Artifacts
+
+- [BC-001] — its Success Criteria stay the only definition of the measures.

+## Checklist Results
+
+| # | Criterion | Status | Evidence/Notes |
+| --- | --- | --- | --- |
+| 1 | The file meets the YAML checklist ([QC-YML-001]) | Pass | See the QC-YML-001 table below; every Mandatory row passes. |
+| 2 | The file is in `.gitea/workflows/` or `.github/workflows/` with the extension `.yml` or `.yaml`, and the same workflow does not exist in both directories | Pass | `.gitea/workflows/ci.yml`; no workflow in `.github/workflows/`. Gitea 1.27.3 ran it (run 2 on branch `mil-001-repository-foundation`). |
+| 3 | The file declares `name`, `on` and `jobs`; `on` lists explicit events and, where it matters, `branches` or `paths` | Pass | `name`, `on` (push with `branches` and `paths`, pull_request with `paths`) and `jobs` are declared. |
+| 4 | A header comment states the purpose, the triggers, the inputs, the secrets it needs, what it changes outside the repository, and the decision or milestone it implements | Pass | The header states purpose, triggers, inputs, secrets, changes outside the repository and the decision. |
+| 5 | Every job and step has a descriptive `name`, unique within its job | Pass | Every step has a unique descriptive `name`. |
+| 6 | The file passes `actionlint` (or the project's workflow validation test) and the tool version is stated | Pass | actionlint 1.7.12 reports no finding; yamllint 1.38.0 as well. |
+| 7 | Every job declares `permissions` explicitly with the least access that works (`contents: read` or none by default); write access only on the job that needs it | Pass | The job declares `permissions: contents: read`. |
+| 8 | Every action used is pinned to a full commit SHA or an exact release tag, never to a branch; a moving major tag (`@v1`) is accepted only for an action published by the same organisation under a stated release policy | Pass | `actions/checkout@v4.2.2` and `actions/setup-python@v5.6.0` are exact release tags. |
+| 9 | No secret is written in the file; a secret is read as `secrets.NAME`, passed to a step through `env:`, never placed on a command line or echoed | Pass | No secret is used or written. |
+| 10 | Untrusted text (`inputs.*`, event fields such as a title, branch name or label, step outputs derived from them) is never interpolated into a `run:` script; it is passed through `env:` and used as a quoted variable | Pass | No event field is interpolated into a `run:` block; `github.ref` is used only in the concurrency group. |
+| 11 | A trigger that gives a run secrets or a write token on code from a fork or an untrusted branch (`pull_request_target`, `workflow_run`) does not check out or execute that code | Pass | No `pull_request_target` or `workflow_run` trigger. |
+| 12 | A workflow that changes state outside the repository (release, tag, publish, sync, deploy) is started by hand or by a protected branch, and a manual run defaults to a dry run with an explicit input to apply | N-A | The workflow changes nothing outside the repository. |
+| 13 | The token the workflow uses has only the scope the job needs, and where the host's built-in token is enough it is used instead of a personal token | N-A | No token is used. |
+| 14 | Every job sets `runs-on` to an explicit label and `timeout-minutes` | Pass | `runs-on: ubuntu-latest` and `timeout-minutes: 10`. |
+| 15 | `concurrency` is set where two runs would conflict: a check cancels the older run (`cancel-in-progress: true`); a publishing job queues (`cancel-in-progress: false`) | Pass | `concurrency` with `cancel-in-progress: true` for a check. |
+| 16 | Triggers are filtered (`branches`, `paths`, `types`) so the workflow runs only for the changes it concerns | Pass | Branch and path filters limit the runs to code and configuration changes. |
+| 17 | Tools and dependencies are installed at pinned versions; a version is a workflow input with a default or a value in one place | Pass | Python version is the one value `PYTHON_VERSION`; development tools are pinned with `==` in `pyproject.toml`. |
+| 18 | A dependency cache is used where the install is slow enough to matter | N-A | The install takes about 15 seconds; a cache would not matter. |
+| 19 | A failing step names the tool, the file and the reason in its log (annotation or `::error::` line) | N-A | Each step is a single tool command whose own log names the file and reason. |
+| 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:` | Pass | The longest `run:` block has two lines. |
+| 21 | Logic used by more than one workflow or repository is a reusable workflow (`workflow_call`) or a composite action; each input has a `description`, a `type` and a `default` where one is sensible | N-A | One workflow; no logic is shared. |
+| 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 | Pass | Verified on Gitea 1.27.3 (`/api/v1/version`): the run completed with conclusion success on runner label ubuntu-latest. |
+| 23 | A reusable workflow states, in its header, how a caller pins it and the script it fetches, so the workflow and its script are the same release | N-A | Not a reusable workflow. |
+| 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 | N-A | Optional; the workflow is linted by actionlint and yamllint in this review, no repeated static test exists for a single file. |
+
+## Referenced Checklist Results (QC-YML-001)
+
+| # | Criterion | Status | Evidence/Notes |
+| --- | --- | --- | --- |
+| 1 | The file parses with a safe YAML loader and has no duplicate keys in any mapping | Pass | Loaded with PyYAML `safe_load`; no duplicate keys (yamllint `key-duplicates`). |
+| 2 | Indentation is 2 spaces everywhere, never tabs; lines end with LF; the file ends with one newline and has no trailing spaces | Pass | 2-space indentation, LF, final newline, no trailing spaces (yamllint default rules). |
+| 3 | Passes `yamllint` (or the project's YAML linter) with its configuration committed next to the code and no unexplained `disable` comments | Pass | yamllint 1.38.0 with `.yamllint.yml` committed; no `disable` comments. |
+| 4 | A scalar that YAML would coerce to another type is quoted: `yes`, `no`, `on`, `off`, `null`, `~`, numbers with a leading zero, versions such as `1.10`, and values that contain `: ` or ` #` | Pass | `"3.13"` is quoted; no coercible scalar remains. |
+| 5 | Only safe, plain types are used: no language-specific tags (`!!python/object`, `!ruby/object`) and no `!include`-style extension unless the consuming tool documents it | Pass | No tags or extensions. |
+| 6 | No secret is written in the file: no password, token, key or private connection string; a secret is referenced by name and supplied by the consuming tool | Pass | No secret. |
+| 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 | Pass | Longest embedded script is two lines. |
+| 8 | A block of keys or values repeated in the file or across files is defined once (an anchor, a template, an include or a reusable unit the consumer supports) | Pass | Nothing repeats beyond the three-line path list used by two triggers; the paths are a different trigger each, accepted because the host has no anchor support in `on:`. |
+| 9 | Anchors, aliases and merge keys (`&`, `*`, `<<`) are used only where the consuming tool is known to support them | Pass | No anchors or aliases. |
+| 10 | The file validates against the schema of the consuming tool where one exists, and the schema or tool version is stated | N-A | Optional: no schema file is available offline; actionlint validates the structure. |
+| 11 | A header comment states what the file is for, which tool reads it, and where its decision or design is recorded | Pass | The header says what the file is for, which tool reads it and the decision. |
+| 12 | Key names follow the convention of the consuming tool; one case style is used within the file (kebab-case or snake_case, never mixed) | Pass | kebab-case for keys such as `runs-on`, `timeout-minutes`; no mixed style. |
+| 13 | Multi-line strings use a block scalar (`\|` or `>`) and state the chomping indicator (`\|-`, `\|+`) where the trailing newline matters | Pass | `run: |` is used for the two-line block with the default clip chomping, which suits a script. |
+| 14 | The file name is lowercase kebab-case with one extension style (`.yml` or `.yaml`) used throughout the repository | Pass | `ci.yml`, lowercase, `.yml` throughout. |
+| 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 | Pass | Exercised by actionlint, yamllint and a real run. |
+
+## Overall Verdict
+
+Go — every Mandatory criterion of QC-WF-001 and QC-YML-001 passes; the workflow ran green on Gitea 1.27.3. The `Doxyfile` output folder is `build/` (not `build/doxygen/` as the MIL-001 task summary says) because Doxygen creates only one directory level; the Go/No-Go criteria are not affected.

+| 11 | Tests exist for new behaviour, are named for the behaviour, and do not depend on order or the network | Pass | Two tests named for the behaviour test the data file. |
+| 12 | Type checker runs in strict mode without errors; `Any` is justified in a comment | Pass | `mypy --strict` reports no issue in 3 files. |
+| 13 | Dependencies are declared and pinned in the project's dependency file, none unused | Pass | Zero runtime dependencies; dev tools pinned exactly. |
+| 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 | Pass | Each literal is defined once in `constants.py`; the test reads names, not copies. |
+| 15 | Imports point inward: business-rule modules import no framework, database, UI or delivery-mechanism code, and there are no import cycles | Pass | The package imports nothing; no cycles. |
+| 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 | Pass | A module with only constants has one reason to change. |
