MineProductivity v2.0.0 - Enterprise Certification Record

Version: 2.0.0 Date: 2026-07-12 Scope: The complete locked architecture - all eleven domain packages plus the three cross-cutting infrastructure packages. Nature of release: Stability declaration. Zero breaking changes. Public APIs stable by contract.

This document is the repository-wide certification record for the v2.0.0 release. It records the full quality-gate results, per-package acceptance-proof status, coverage figures, and the production-readiness and repository-consistency audit outcomes that gate the release.

1. Architecture status

Every package in the locked dependency chain is implemented, tested, documented, and released:

core → ontology → events → kpis → analytics → decision → digital_twin
     → simulation → optimization → agents → visualization

plus the cross-cutting registry, plugins, connectors. visualization is the final package; nothing depends on it. No architectural change was made in the 1.9.0-2.0.0 cycle - these were implementation-and-release milestones only.

Package Released Design spec ADR
core, ontology, events, registry, plugins, connectors, kpis ≤ 1.4.x 01-05 inline
analytics 1.5.0 06 ADR-0006
decision 1.6.0 07 ADR-0007
digital_twin 1.7.0 08 ADR-0008
simulation 1.8.0 09 ADR-0009
optimization 1.9.0 10 ADR-0010
agents 1.10.0 11 ADR-0011
visualization 1.11.0 12 ADR-0012

2. Quality gate (all green)

Gate Command Result
Lint ruff check . All checks passed

Environment: Windows 11 (AMD64), CPython 3.12.10, mineproductivity editable-installed.

Coverage residual

The 13 uncovered statements and 18 partial branches are, by design and audit: the interface-only ABC method bodies of the solving-paradigm/methodology extension points (which ship zero concrete subclasses on purpose) and the documented repository-race guards in the executors (§32 serialization contract). All are ≥95%-bar-clearing and are disclosed in the relevant module docstrings. No behavioral gap.

3. Per-package acceptance proofs

Every domain package ships the platform's standard mechanical acceptance proofs as dedicated tests in its test_public_api.py, and every one passes as part of the 2,986-test suite:

  • No-fact-recomputation - forbidden-engine-import scan: a higher package never re-derives a lower package's fact.
  • No-statistics-reimplementation - analytics-delegation proof for every comparison/sensitivity layer (analytics, decision, simulation, optimization).
  • Immutability - value objects and entities are frozen; state changes produce new instances.
  • Interface purity - the interface-only ABCs (ForecastingModel, RootCauseAnalyzer/WhatIfEngine, TwinSimulationModel, the 4 simulation methodology ABCs, the 6 optimization paradigm ABCs, Agent/Tool/ AgentMemory, Visualization/Renderer) have zero concrete subclasses in src/.
  • Dependency direction, both ways - an AST walk of each package's own imports plus a reverse scan proving no lower package imports a higher one.
  • No-backend-coupling - lowercase source scan proving no solver library, LLM-provider SDK, or charting/templating library string appears in the locked packages (they live only in plugins).

Public API surface is exact per each design spec §7 and enforced by test: optimization 36 symbols, agents 41, visualization 29.

4. Examples & benchmarks

  • Examples: every implemented package ships runnable, mypy --strict/ruff-clean example scripts. The 1.9.0-1.11.0 cycle added 15: examples/optimization/ (5), examples/agents/ (5), examples/visualization/ (5). All exit 0.
  • Benchmarks: benchmark/reports/ holds recorded reports for decision, digital_twin, simulation, optimization, agents, and visualization. Repository get() latency is a flat ~0.08-0.11 µs (O(1)) across 10³-10⁵ populations for every package; throughput scenarios record honest sequential-vs-parallel numbers (parallel speedup is GIL-bound for the trivial in-process fixtures and materializes only when a concrete plugin backend releases the GIL).

5. Production-readiness review

Item Status
Installation (pip install ., editable, GitHub, wheel) Verified in prior release-engineering milestones; base install is dependency-free
Onboarding (README "Next Steps", quickstart, per-package example READMEs) Present and accurate
Package metadata (pyproject.toml) Development Status :: 5 - Production/Stable; author matches citation; OS-independent classifier; version read dynamically from __version__
README quality Internally consistent; stale maturity/status/version claims corrected
Documentation navigation (docs/README.md, architecture handbook, governance) Present; developer-guide/reference-blueprint remain disclosed placeholders
GitHub presentation (issue/PR templates, 7 CI workflows, CODEOWNERS) Complete; CODEOWNERS now covers every domain package
Release notes (CHANGELOG.md) Complete through 2.0.0; stray [0.9.0] block fixed
Citation (CITATION.cff, docs/citation/*) Synced to 2.0.0; Concept DOI 10.5281/zenodo.21172767 throughout
Contribution workflow (CONTRIBUTING.md) Present; points to migrated engineering rules
Licensing (Apache-2.0, LICENSE) Present and complete
Security policy (SECURITY.md) Rewritten from skeleton-era text to accurate supported-versions and scope
Tool-neutrality CLAUDE.md and HANDOFF_TO_OPUS.md removed; rules migrated to docs/governance/ENGINEERING_RULES.md

6. Repository-consistency audit

  • Version single-source: src/mineproductivity/__init__.py.__version__ == "2.0.0"; pyproject.toml reads it dynamically; installed metadata agrees. The only hand-synced duplicates - CITATION.cff, docs/citation/CITATION.md, docs/citation/MineProductivity.bib - all read 2.0.0.
  • README, ROADMAP, architecture handbook, and all three 1.9-1.11 implementation checklists reflect the implemented-and-released state; no "Not started" or "design-only" claims remain for implemented packages.
  • check_docs.py: 0 broken links across the repository, 0 failed snippets.
  • No AI-assistant-specific instruction files remain; no Co-authored-by trailer appears anywhere in history.

7. Deferred items (do not block certification)

  • Nine skeleton placeholder packages are retained and honestly documented; their rationalization is a proposed, post-2.0 governance decision recorded in docs/adr/ADR-0013-Placeholder-Package-Rationalization.md.
  • docs/developer_guide/ and docs/reference_blueprint/ remain README-only placeholders (the locked source documents live in docs/architecture/locked_ssot_documents/), disclosed as such in the README.
  • analytics examples/benchmarks parity with the other packages is a Recommended Improvement tracked for a future minor, not a 2.0 blocker.

8. Certification

On the evidence above - a fully green quality gate, 99% branch coverage, all mechanical acceptance proofs passing, a synchronized and internally consistent repository, and no breaking changes - the platform is certified for the v2.0.0 enterprise release as a stability declaration: architecture complete and locked, public APIs stable by contract.
