Why This Extension

Most assistants stop at "generate code". This extension goes further: it helps teams govern AI code changes with policy controls, auditability, and measurable outcomes.

What's New (v4.x)

• Policy-as-code with extends, imports, and profiles (strict, balanced, experimental)
• Domain-aware risk and trust scoring
• Dual approval for high-risk overrides
• Tamper-evident chain-of-custody (HMAC + hash chain)
• Optional Git provenance (branch/commit metadata with chainId + sourceHash)
• Governance heatmap by domain in Webview
• Governance experiment metrics CLI (yarn run eval:governance)

Release Highlights (4.1.0)

• Policy Imports for reusable governance modules via imports in .ollama_policies.json
• Expanded Governance Heatmap with domain-level rollback/validation/block/override rates
• Top triggered rule per domain + clickable domain rows for governance prompt drafting

Open Super Chat

1. Open View -> Chat
2. Type @ollama-cloud-chat
3. Run /provider to select endpoint + model

Commands

Modes

• code: explain, refactor, tests, fix, review, security
• ds: eda, sql, features, train_eval, debug, doc
• devds: end-to-end software + data workflow
• devops / infra: PowerShell-first operations guidance
• pbi: pbi_model, pbi_m, pbi_dax, pbi_visuals, pbi_checks

Premium Webview Features

• Presets for common workflows
• Quick Prompts chips (one-click task starters)

• Provider/model/mode/action/context controls
• Setup Rapido section: Usar Local, Conectar Cloud, Escolher Modelo Local, Testar Ollama Local
• One-click Local/Cloud switch with clearer visibility
• Cloud-selected UI shows inline Login and Set Token actions
• Local runtime health in panel (online/offline + model count)
• If Cloud is selected without token, chat auto-falls back to Local Ollama

Governance Layer

• Policy guardrails before apply (.ollama_policies.json)
• Domain-level enforcement and explainability
• Trust-based gating from observed behavior
• Override audit with justification + optional dual approval
• Tamper-evident custody trail:
  • .ollama_copilot_apply_chain.jsonl
  • chainId, signatures, prevHash, entryHash
• Optional Git provenance for repository-level evidence
• Domain heatmap for operational tuning

Governance Experiment

yarn run eval:governance --splitDate 2026-02-01T00:00:00Z --out governance-report.json

This produces domain-level metrics for:

• rollback rate
• validation success rate
• block/override rate
• baseline vs governed deltas

Development

yarn compile
yarn test

Local-first

Supports:

• Local Ollama (http://localhost:11434)
• Remote Ollama-compatible APIs
