Intent

Problem: The repository holds only planning documents. Every later story needs a runnable, secure and configurable Django container to build on.

Approach: Create the Django 5.2 LTS project with environment-variable configuration that fails fast, a database-only health check, JSON logs with a request id, a strict security-header layer, a multi-stage Docker image with compose file, and a test setup.

Boundaries & Constraints

Always: All configuration comes from environment variables, validated at startup; one error message lists every invalid or missing variable and the process exits non-zero. Nothing in the repository names ping-mee, a domain, an OU, a group, an IP or a path. Secrets never appear in logs. One gunicorn worker with threads. The container runs as a non-root user; only /data and /backups are writable. /healthz checks the database only. Python 3.13, Django 5.2 LTS. Spine rules AD-13 and AD-18 apply. Decision: the image is built and run on the Linux host from a checkout of this repository (Docker is not installed on the development machine); no registry or pipeline in this story.

Never: No AD, OIDC, mail, share or feature-app code (later entries). No python-ldap dependency yet. No inline script or external asset anywhere. No Django admin. No commit of secrets, and no real .env.

I/O & Edge-Case Matrix

Scenario	Input / State	Expected Output / Behavior	Error Handling
Valid start	All required variables valid	Migrations run, server answers	No error expected
Invalid config	A required variable missing or malformed	Process exits non-zero, message names every bad variable	No traceback, no secret value printed
Health ok	GET /healthz, database reachable	200 {"status":"ok"}	No error expected
Health down	Database unreachable	503 {"status":"unavailable"}	Logged without secrets
Headers	Any response	CSP, nosniff, frame deny, referrer policy, X-Request-ID present	No error expected
Request log	Any request	One JSON log line with request id, method, path, status	Query strings and bodies not logged

Code Map

Greenfield: only planning documents exist. New files, using the spine's source tree.

• pyproject.toml, uv.lock, .python-version -- dependencies (Django, gunicorn, whitenoise; dev: pytest, pytest-django, ruff)
• manage.py, portal/config/ -- settings.py, env.py (typed parsing, collects all errors), urls.py, wsgi.py, logging.py (JSON formatter), middleware.py (request id, security headers), health.py
• portal/adapters/__init__.py -- empty package for later adapters and fakes
• portal/tests/ -- conftest.py, config, health, header and logging tests
• Dockerfile, compose.yaml, .dockerignore, docker/entrypoint.sh -- multi-stage image, non-root, migrate then gunicorn
• .env.example, README.md -- documented variables and run steps
• Reuse: spine AD-13, AD-18. Do not change: anything under _bmad/, _bmad-output/, .agents/, context-resources/.

Tasks & Acceptance

Execution:

• pyproject.toml, .python-version -- project metadata and pinned dependencies -- repeatable installs
• portal/config/env.py -- typed variables (SECRET_KEY, ALLOWED_HOSTS, DATA_DIR, DEBUG, TRUSTED_PROXIES, LOG_LEVEL, DEFAULT_TIMEZONE) with defaults only for safe values -- fail fast
• portal/config/settings.py, urls.py, wsgi.py -- SQLite in WAL mode under DATA_DIR, secure cookies, CSRF, whitenoise, UTC storage, translation on -- spine baseline
• portal/config/middleware.py, logging.py, health.py -- request id, headers, JSON logs, /healthz
• Dockerfile, docker/entrypoint.sh, compose.yaml, .dockerignore -- image and run definition
• portal/tests/ -- unit-test the matrix rows
• .env.example, README.md -- document every variable and the run steps

Acceptance Criteria:

• Given valid variables, when the app starts, then migrations apply and /healthz returns 200.
• Given a missing SECRET_KEY and a malformed LOG_LEVEL, when the app starts, then it exits non-zero naming both.
• Given the database file is unreadable, when /healthz is called, then it returns 503.
• Given any request, when the response is sent, then the CSP forbids inline scripts and external sources and the log line has the request id.
• Given the repository, when searched, then it contains no ping-mee name, domain, IP or path.

Implementation Notes

• Implemented by a coding subagent from this plan; the diff was read and uv run pytest (12 passed, none skipped) and uv run ruff check . were re-run by the orchestrator.
• Beyond the plan: docker/healthcheck.py (the container probe needs a Host header that matches ALLOWED_HOSTS, otherwise it gets a 400); .gitattributes (keeps LF in .sh and Dockerfile on Windows checkouts); extra headers (Permissions-Policy, COOP); HSTS of one year when DEBUG=false, which needs the proxy to send X-Forwarded-Proto.
• README.md was rewritten and no longer carries the original project name line.
• Ruff excludes _bmad, _bmad-output, .agents and context-resources.
• The 503 criterion is tested with a mocked unreachable database, not an unreadable file.
• Not verified: the Docker build, the read-only root file system with gunicorn's worker temp dir, the uv image tag and the container health check. They need docker compose up --build on the Linux host.
• compose.yaml publishes port 8000 on all host interfaces. Bind it to a specific address if the reverse proxy runs on the same host.
• Resolved versions in uv.lock: Django 5.2.18, gunicorn 26.2.0, whitenoise 6.12.0.

Review Triage Log

Pass 1 (quick lens). Counts: high 1, medium 3, low 3, false 1, maybe-false 0.

#	Finding	Verdict	Route	Evidence
1	docker/entrypoint.sh not executable	high	patch	Added as mode 100644 and COPY docker ./docker has no chmod, so ENTRYPOINT on the Linux host fails with permission denied; "Valid start" would not hold.
2	Security headers missing on responses from outer middleware	medium	patch	SecurityHeadersMiddleware is innermost; a bad Host 400 from CommonMiddleware, whitenoise static files and SecurityMiddleware redirects never pass through it. The AC says any request.
3	Query string and request repr in Django's own error log lines, and a second line per 4xx	high	patch	Reproduced: a 404 for /missing?token=supersecret writes a django.request line containing <WSGIRequest: GET '/missing?token=supersecret'>. Breaks "query strings not logged" and "one line per request".
4	TRUSTED_PROXIES parsed but unused; SECURE_PROXY_SSL_HEADER trusts any client	medium	patch	Nothing reads it until the sign-in entry (client IP rule); docs say it restricts proxies. The fix here is wording; wiring is entry 5. The proxy-header trust has no demonstrated harm yet (low, rejected).
5	/tmp tmpfs is a third writable location	low	rejected	Ephemeral and needed for gunicorn workers; the rule's intent (persistent writable paths) holds; changing it adds complexity.
6	Gunicorn error log is plain text on stderr	low	rejected	Server start and error lines only; app logs are JSON. A JSON gunicorn log config is more than a direct correction.
7	"No ping-mee name" not satisfiable because of the plan file	false	rejected	The criterion covers code and image; .dockerignore excludes _bmad-output and a search outside protected folders found nothing.
8	503 criterion tested with a mock, not an unreadable file	low	rejected	Disclosed in Implementation Notes; the view returns 503 on any exception from cursor(), so a real failure cannot return 200. A real-file test needs database wrapper plumbing.

Design Notes

CSP is a constant in middleware.py (default-src 'self', script-src 'self', frame-ancestors 'none') so story 6 can adjust the style rules for the Fluent components without weakening script rules. Dependencies were checked on the web: Django 5.2 supports Python 3.10 to 3.14 and is LTS to April 2028; gunicorn 26.x and whitenoise 6.12 support it. Python 3.13 is pinned because this machine's default 3.15 is not supported by Django 5.2.

Verification

Commands:

• uv run pytest -- expected: all tests pass
• uv run ruff check . -- expected: no findings
• uv run python manage.py check --deploy with a valid test environment -- expected: no errors
• uv run python manage.py check with missing SECRET_KEY -- expected: exit non-zero listing the variable

Manual checks (if no CLI):

• Docker is not installed on this machine. On the Linux host: docker compose up --build, then curl http://localhost:8000/healthz returns {"status":"ok"}, and starting with an invalid variable shows the error and exits.
