Product surface
Steady Hand ONE and bounded product lanes accept ordinary, permitted work.
Product architecture
Google-native where it helps. Human-governed where it matters.
The target architecture joins a measurable cloud runtime with a familiar human review layer. AI assists with bounded work; people retain authority for truth, exceptions, release, and external action.
Identity
Firebase Authentication or Google identity services limit access to approved participants.
Execution
Cloud Run hosts reproducible APIs and controlled workflow orchestration.
AI assistance
Vertex AI and Gemini support classification, drafting, and evaluation inside explicit bounds.
State and evidence
Firestore and Cloud Storage preserve job state, approvals, outputs, and sanitized evidence.
Control
Secret Manager, IAM, Logging, and Monitoring protect access and measure reliability, quality, and cost.
Human layer
Drive, Docs, Sheets, and Gmail support review, evidence, reporting, and approved communication.
Scale path
Preview → controlled pilot → authenticated cloud product
The immediate goal is one reproducible end-to-end MVP with synthetic intake, bounded AI assistance, a human approval checkpoint, evidence receipt, and measured cost, retry, export, and deletion controls.
