validation pass

Verdict: PASS

Ticket

ldraney/postmark-account-sdk#2 (board item #1915 on board-postmark) — Python SDK for all 23 Postmark Account API endpoints with full integration test suite.
Merged PR: #5 — squash-merged as daeee3d on origin/main.

Environment

Tier 1 (local). SDK is a Python library — no deployment target. Validation = merge commit on origin/main, package installs, tests pass against real Postmark Account API.
Test runner: Python 3.14.5, pytest 9.1.1, httpx 0.28.1. API token sourced from ~/secrets/postmark/account/.env.

Checks

# Criterion How Verified Result Evidence
1 Merge commit present on origin/main <code>git fetch origin &amp;&amp; git log origin/main --oneline</code> PASS Commit <code>daeee3d</code> — "Sprint 2: SDK implementation -- 23 endpoints, 4 groups, integration tests (#5)"
2 Package installs with dev deps <code>pip install -e ".[dev]"</code> in clean venv PASS Successfully installed postmark-account-sdk-0.1.0 with httpx, pytest, ruff, python-dotenv
3 Project structure matches AC file tree <code>find . | sort</code> compared to acceptance-criteria.md PASS All 15 files present: 4 source modules + client + __init__ + py.typed, 4 test files + conftest + __init__, pyproject.toml, .gitignore, docs/
4 CLAUDE.md symlinks to README.md <code>ls -la CLAUDE.md</code> PASS <code>CLAUDE.md -&gt; README.md</code>
5 README.md TOC links to all docs Read README.md content PASS Links to architecture.md, user-story.md, acceptance-criteria.md
6 pyproject.toml: httpx dep, pytest/ruff dev deps Read pyproject.toml PASS <code>dependencies = ["httpx&gt;=0.27"]</code>, dev = <code>["pytest&gt;=8.0", "python-dotenv&gt;=1.0", "ruff&gt;=0.15"]</code>
7 ruff check — zero errors <code>ruff check .</code> PASS "All checks passed!" exit code 0
8 ruff format --check — zero diffs on source <code>ruff format --check .</code> PASS 16 Python files already formatted. 1 markdown doc (user-story.md) has code-block formatting nit — cosmetic, non-blocking
9 23 SDK methods across 4 groups (1:1 with swagger) Introspected module classes PASS ServersAPI: 5 (list, create, get, edit, delete). DomainsAPI: 9 (list, create, get, edit, delete, rotate_dkim, verify_dkim, verify_return_path, verify_spf). SendersAPI: 8 (list, create, get, edit, delete, request_new_dkim, resend_confirmation, verify_spf). TemplatesAPI: 1 (push). Total: 23.
10 23 tests pass against real Postmark API <code>pytest tests/ -v</code> with POSTMARK_ACCOUNT_TOKEN PASS 23 passed in 5.73s. test_domains(9) + test_senders(8) + test_servers(5) + test_templates(1) = 23.
11 PostmarkAccountClient importable <code>from postmark_account_sdk import PostmarkAccountClient</code> PASS Import succeeds, client class accessible

Regression Check

SDK is a new library with no prior version — no regressions possible. Verified the package does not conflict with existing Python environment (clean venv install succeeded with no dependency conflicts).

Discovered Issues

ruff format --check flags 1 markdown file (docs/user-story.md) for code-block formatting. This is cosmetic — all 16 Python source and test files are properly formatted. Non-blocking; may be addressed in a future cleanup pass.
