23 tables + alembic_version covering the v1 data model:
- Auth/RBAC (8): users, groups, permissions, user_groups, group_permissions,
invitations, invitation_groups, refresh_tokens.
- MITRE (4): mitre_tactics, mitre_techniques, mitre_subtechniques + the
technique↔tactic many-to-many.
- Templates (4): test_templates, test_template_mitre_tags (3 nullable FKs +
CHECK exactly_one_mitre_fk), scenario_templates, scenario_template_tests
(UUID PK + UNIQUE(scenario_id, position) so a test can appear at multiple
positions).
- Missions (6): missions, mission_members, mission_scenarios, mission_tests,
mission_test_mitre_tags (deliberately denormalised — copies external_id +
name + url, no FK to mitre_* — so a re-sync of the catalogue can't purge
historical tags), mission_categories.
- Evidence/settings/notifications (5): evidence_files, settings (JSONB
value), detection_levels, notifications.
SQLAlchemy 2.x with Mapped[]/mapped_column(), pk_/fk_/ck_/uq_/ix_ naming
convention. Reusable mixins (UuidPkMixin, TimestampMixin, SoftDeleteMixin —
no auto __table_args__ since classes silently clobber the mixin's).
Soft delete: deleted_at + partial indexes ix_<table>_active WHERE deleted_at
IS NULL on 9 tables (users, groups, test_templates, scenario_templates,
missions, mission_scenarios, mission_tests, mission_categories,
evidence_files). Notifications gets ix_..._unread WHERE read_at IS NULL.
CHECK constraints for status / state / opsec_level / mitre_kind enums.
New API endpoint GET /api/v1/diag/db: returns alembic_revision (short hash)
and the public-schema table_count. 503 with {"reachable": false} on a DB
outage. Database card on the SPA home consumes it.
Test stage in backend/Dockerfile (--target test): runtime + dev extras +
tests/. New make test-api spins an ephemeral pytest container against the
live DB on the compose network. backend/tests/test_schema.py: 8 integration
tests (tables, FK pairs, CHECK constraints, partial indexes, alembic-at-head,
negative INSERT proving the exactly_one_mitre_fk CHECK fires).
e2e/tests/m1-db.spec.ts: 4 Playwright tests covering the diag endpoint
contract + the Database card + footer/roadmap labels.
DoD: make clean && make up && make migrate → 23 tables, 32 FKs, 9 CHECKs,
make test-api → 9 passed, make e2e → 12 passed.

- Repo scaffolding: .gitignore, .env.example, Makefile, docker-compose.yml,
README.md, CHANGELOG.md, pre-commit config.
- Three-service stack: api (Flask 3), db (postgres:16-alpine), front (nginx
serving the Vite bundle). Named volumes metamorph_db + metamorph_evidence.
- Backend skeleton: Flask app factory, JSON structured logging on stdout,
GET /api/v1/health, multi-stage Dockerfile, pyproject.toml driven by uv,
Pydantic Settings with secret guard rails (refuses to boot in non-dev with
placeholders), APP_ENV gating.
- Frontend skeleton: Vite + React 18 + TypeScript strict + TailwindCSS, RTOps
design tokens from tasks/design.md, self-hosted JetBrains Mono / IBM Plex
Sans via @fontsource, base UI primitives (Card/Tag/SectionHeader/FlowNode/
Button), home page wired to /api/v1/health.
- Engine-agnostic Makefile: auto-detects docker or podman, picks the matching
compose driver. Targets: up/down/build/rebuild/dev/lint/fmt/test/migrate/
seed-mitre/print-install-token/e2e/inspect-health.
- Playwright suite: e2e/tests/m0-smoke.spec.ts (8 tests) + HTML + JUnit
reports + traces on retry.
- Docs: tasks/spec.md (finalized after Q&A), tasks/design.md, tasks/todo.md
(14 milestones), tasks/testing-m0.md, tasks/lessons.md.
DoD: make up + make health + make e2e all pass on podman 5.x (Fedora) and
docker. TLS terminated by external reverse proxy (spec §6 NF-network).
