ArchGround Architecture Change Gate showing a baseline comparison and reviewed decisions — Deterministic Demo Mode · Atlas AI Commerce

Local deterministic coreMapping, inspection, editing, and export need no account or AI provider.

Evidence, not decorationEvery generated claim keeps its citation, provenance, confidence, and review state.

Built for reviewDrift, AI-system boundaries, and export contents remain explicit and inspectable.

Not another decorative diagram

Every shape earns its place.

ArchGround turns supported declarative evidence into a layered, keyboard-accessible system map. Generated and user-authored material stay distinct, so the map can become a reviewable system record instead of an untraceable picture.

Architecture Change Gate

Capture a named evidence baseline, rescan with the saved repository permission and configuration, and review typed changes without modifying repository files.

Grounded Map

Scan one user-selected repository locally and model typed services, packages, APIs, databases, deployments, external systems, and AI tools.

AI System Lens

Review agents, models, tools, permissions, approval gates, data flows, secrets, trust boundaries, and explainable risk prompts.

Verified 1.0.0 product views

Map the system. Trace the evidence. Review the change.

Every image below is rendered from ArchGround's deterministic built-in Demo Mode at a fixed locale, appearance, scale, and window size.

Gate architecture changes before they ship.

Capture a baseline, compare a later local scan, and record an explicit disposition and note for every evidence-backed change.

Turn a codebase into a map you can trust.

Supported declarative files become an editable Grounded Map without running repository code.

Every shape comes with proof.

Inspect the repository-relative file, line range, content hash, provenance, confidence, and review state behind each claim.

Map every agent, tool, permission, and approval.

Model agents, models, MCP servers, tools, approval gates, secrets, data sources, trust boundaries, and review prompts.

Export every reviewed gate with its evidence.

A completed gate adds deterministic JSON and Markdown decisions to the broader Architecture Review Pack.

Reviewed Change Gate

Know exactly what leaves the workspace.

After every change has a disposition and note, preview exact sizes and SHA-256 hashes, then export change-gate.json, CHANGE-GATE.md, and the validated Architecture Review Pack.

Unreviewed changes cannot be presented as a completed gate
Evidence and decision notes travel with the map
Deterministic files with inspectable hashes
Source snippets excluded in version 1.0.0

Private local core

Your architecture stays under your control.

Deterministic mapping, inspection, editing, and export require no account or AI provider.

No telemetry, analytics, ads, subscription, updater, cloud sync, or Trieflow proxy.

ArchGround never runs repository builds, scripts, shells, package managers, hooks, filters, plugins, or downloaded code.

Provider sending is not connected to live workspace controls in version 1.0.0.

Optional provider boundary

Libraries are ready. Live sending is not.

The adapter library includes OpenAI, Anthropic, Google Gemini, Azure OpenAI, user-configured OpenAI-compatible HTTPS, Ollama, and LM Studio. It implements Keychain credentials, redaction, exact request previews, endpoint validation, bounded transport, and evidence-cited response validation.

Clear limits, by design

What ArchGround does not claim.

Saved-scope rescan. Live rescan uses the saved repository permission and scan configuration. If macOS cannot restore that permission, ArchGround requires repository reselection. Branch or commit selection is not included in 1.0.0.

Bounded discovery. Declarative adapters are bounded heuristics. They do not discover every dependency, observe runtime truth, prove correctness, find vulnerabilities, certify compliance, or guarantee that a third-party provider is private.

Bounded import. Direct canvas import is draw.io-compatible XML only. Text diagram languages and general image import are not claimed.
