Morphism Systems — Session Continuation Handoff

You are resuming work on the morphism-systems monorepo. Repo: C:\Users\mesha\Desktop\GitHub\github.com\morphism-systems\morphism Branch: codex/category-theory-validation-matrix Platform: Windows 11 native + WSL2 (Ubuntu-24.04)

What was completed in your last session

Category-theory session summary — created docs/governance/category-theory-session-summary.md, linked in mkdocs.yml and docs/governance/index.md. Covers all 7 invariants, 10 tenets, 9 theorems, agent states, drift taxonomy, ASCII diagrams.
Full-stack validation entrypoint — scripts/validate-full-stack.sh is the canonical bootstrap + validation command. Supports --skip-supabase (default) and --with-supabase. Stamp-guarded warm skips for Python/npm installs. Logs to .morphism/validation/<timestamp>/.
Tenet matrix — tests/test_tenet_matrix.py with 10 explicit tests, one per tenet (T1-T10), each mapped to a real enforcement surface (ssot_verify, validate_commit, validate_branch, policy_check, docs_graph, dependency_health, runbook_coverage, maturity_score, etc.).
Theorem matrix — tests/test_theorem_matrix.py with 9 explicit tests, one per theorem, each mapped to an executable witness (SSOT uniqueness, drift/refusal paths, structured commit traces, scope binding, entropy monotonicity, refusal totality, minimal authority, convergence certificates, monad laws).
Drift taxonomy — tests/ground_truth/drift_taxonomy.json as canonical scenario catalog. tests/test_drift_taxonomy.py for validation. benchmarks/drift_taxonomy.py for benchmarking. Covers basic drift (missing_frontmatter, stale_date, broken_link, missing_invariant_ref, encoding_mismatch) and complex drift (subtle-below-threshold, gradual degradation, three-way, no-shared-dimension non-drift, empty-section non-drift, overlapping-jurisdiction, proof/API mismatch, migration/schema drift).
Design-tokens test gap fix — packages/design-tokens/ now has a real Vitest suite (src/__tests__/registry.test.ts) and test script, so turbo run test is a complete matrix.
App theorem coverage — apps/morphism/src/__tests__/governance-proofs-page.test.tsx, governance-proofs-route.test.ts, supabase-local.integration.test.ts. Extended tests/e2e/smoke.test.ts with deployed theorem surface checks.
Docker setup renewed — Root-level Dockerfile (single-stage, Python 3.11 + Node 22), docker-compose.yml (5 services: validate, policy-check, maturity-score, test, dev), .dockerignore, DOCKER.md. Legacy templates/docker/ deleted. Docker Desktop running with WSL2 integration confirmed working.

What remains to be done

Immediate (complete the validation matrix)

Run validate-full-stack.sh --skip-supabase to completion. It has been tested but not run end-to-end in a single clean pass. The warm-run stamp guards are in place. On Windows/WSL, run from a WSL-native path (~/morphism) for speed, not from /mnt/c/.
Run validate-full-stack.sh --with-supabase. Docker is now available in WSL. Supabase CLI is present (v2.76.15). This path does: cd apps/morphism npx supabase start npx supabase db reset npm run test -- src/tests/supabase-local.integration.test.ts npx supabase stop
Run npm run test:staging with a real target. Set STAGING_URL=https://morphism.systems (or your Vercel preview URL). For authenticated checks, also set STAGING_AUTH_COOKIE.
Docker image build. The docker build -t morphism:latest . is in progress but hit a pip timeout downloading numpy. The Dockerfile has been updated with --timeout 300. Retry: docker build -t morphism:latest . docker compose up validate

Residual items

packages/design-tokens still emits tsup warnings about exports.types ordering during build. Doesn't fail lint/typecheck/test but worth cleaning up in packages/design-tokens/package.json.
Full Python test suite (npm run test:python) — 665 tests. Was stopped mid-run due to /mnt/c slowness. No failures observed before stop. Run on WSL-native path.

Key architecture facts

Monorepo: TypeScript (Next.js 15 + Turborepo) + Python (category theory engine)
Governance kernel: 7 invariants (I-1..I-7), 10 tenets (T-1..T-10), 9 theorems
Branch naming: Must use valid prefixes (feat, fix, chore, ci, docs, refactor, test, perf, hotfix, codex, build, release, feature)
Python: Use python not python3. Windows 11 native.
Convergence kappa < 1: Design target and executable metric, NOT a machine-checked formal proof
SSOT trinity: AGENTS.md → SSOT.md → GUIDELINES.md

Your task

Continue from where the last session left off. Priority order:

Complete the Docker image build and verify docker compose up validate passes
Run validate-full-stack.sh --with-supabase (Docker is now available in WSL)
Run the full Python test suite to completion
Run staging smoke tests if a STAGING_URL is available
Commit the complete changeset with a conventional commit message
Open a PR to main summarizing the category-theory validation matrix work The Docker build is still running in the background. Want me to check on it, or is the handoff prompt what you needed?
