v1.9.0 — Signed Skills and Deterministic Workflows

Purpose: Defines only the architecture delta from the canonical Forgevena platform blueprint. Audience: product, architecture, engineering, security, operations, documentation, release, and AI coding agents Owner: Workflow and Engineering Assets Maintainers Roadmap authority: docs/strategy/FORGEVENA_VERSIONED_PRODUCT_ROADMAP.md#12-v190--signed-skills-and-deterministic-workflows Lifecycle: planned Review: before implementation and at every lifecycle promotion

Architecture Delta

Add signed skill, prompt, and rule registries plus a DAG/state-machine engine that reuses policy, providers, plugins, state, audit, and consent.

Component and Module Boundaries

Committed features remain behind existing application-context, state, policy, consent, audit, and rollback services. No feature may introduce a parallel authority.

Data and Control Flow

Inputs are schema-validated, classified, and policy-evaluated. External effects stop at consent boundaries. Outputs contain metadata and evidence references, while secrets and sensitive content remain excluded.

Dependencies

  • v1.8.0

Failure Modes

  • Partial operations recover from journals or last-known-good state.
  • Unsupported compatibility fails visibly.
  • Missing credentials, approval, billing, or network access stops at preflight.
  • Corrupt or unverifiable evidence blocks promotion.
