Summary

Adds a comprehensive specification section for milestone v3.5.0 (Autonomy Hardening) to docs/specification.md, covering the A2A Facade Module, Guard System, Hierarchical Decomposition Engine (4+ levels), Parallel Execution Subsystem (10+ concurrent subplans), Validation-Gated Apply, and cross-cutting concerns. Scope adjustments documented: server stubs moved to M9 (v3.8.0) per ADR-047/ADR-048; TUI features moved to M8 (v3.7.0).

Changes

  • docs/specification.md: Added 431 lines covering the v3.5.0 Autonomy Hardening detailed specification section with the following subsections:
    • Overview of autonomy hardening objectives
    • A2A Facade Module (session management, plan lifecycle, event queue pub/sub)
    • Guard System (denylist, budget caps, tool call limits, automation profile resolution precedence)
    • Hierarchical Decomposition Engine (4+ level subplan decomposition, selective subtree recomputation)
    • Parallel Execution Subsystem (concurrency model, resource management, 10+ concurrent subplans)
    • Validation-Gated Apply (validation pipeline and gate enforcement)
    • Cross-Cutting Concerns (error handling, observability, configuration)
    • Acceptance Criteria (functional and technical criteria mapping)
    • ADR References (ADR-047 and ADR-048)

Sections Added

  1. Overview — What autonomy hardening means and why it's needed
  2. A2A Facade Module — Session management, plan lifecycle via A2A, event queue pub/sub, module boundaries
  3. Guard System — Denylist, budget caps, tool call limits; enforcement pipeline; automation profile resolution precedence (plan > action > global)
  4. Hierarchical Decomposition Engine — 4+ level subplan decomposition, subplan spawning, selective subtree recomputation for decision correction
  5. Parallel Execution Subsystem — Concurrency model, resource management, result aggregation (10+ concurrent subplans)
  6. Validation-Gated Apply — Validation pipeline, gate enforcement
  7. Cross-Cutting Concerns — Error handling, observability, configuration
  8. Acceptance Criteria — Functional and technical criteria mapping to milestone acceptance criteria
  9. ADR References — ADR-047 (A2A Standard Adoption) and ADR-048 (Server Application Architecture) as primary references

ADR References

  • ADR-047 — A2A Standard Adoption (governs A2A facade design)
  • ADR-048 — Server Application Architecture (explains server stub deferral to M9)

Classification

This is a MAJOR change requiring the needs feedback label (label ID 1401).

Testing

Documentation review and specification validation against milestone acceptance criteria and referenced ADRs (ADR-047: A2A Standard Adoption, ADR-048: Server Application Architecture).

Grooming Analysis for PR #9944

Quality Issues Found:

  1. Missing Type Label: PR lacks a Type/ label. This is a specification/documentation PR and should have Type/Spec label.
  2. Missing Priority Label: PR is marked as a "MAJOR change" but lacks a Priority/ label. Should have Priority/High label.
  3. Missing Milestone: PR content references v3.5.0 milestone but is not assigned to it. Should be assigned to v3.5.0 (ID 108).

Fixes Applied:

Added Type/Spec label
Added Priority/High label
Set milestone to v3.5.0

Summary:

PR is well-structured with comprehensive specification content for Autonomy Hardening. The "Needs Feedback" label is appropriate for a major specification change. All quality issues have been resolved.
