Authority Stack

PyHarness

Master harness and primary runtime enforcement plane

Reviewer

Proof, evidence, acceptance, and independent review authority

Goal Harness

Goal, spec, and architecture mutation authority

MetaFactory

Capability registry and runtime fitness source of truth

Provider Packs

Future compiled adapters only — NOT source of truth

Subatomic Control Plane — S0 through S11

S0STANDBY

Model Energy Core

Gate: Model availability and response integrity

Linked: RS-015 | Hooks: PyHarness, Reviewer, Provider Pack

No automated model health probe. Provider pack routing future-only.

S1STANDBY

Context Field

Gate: Context integrity and injection correctness

Linked: RS-001 | Hooks: PyHarness, Memory/Registry

Context injection is manual. No automated freshness or overflow detection.

S2DEGRADED

Tool Particle Field

Gate: Tool availability and output integrity

Linked: RS-005, RS-006, RS-007, RS-008 | Hooks: PyHarness, Reviewer

RS-001 through RS-010 sealed at 100%. 15/20 RS functions operational.

S3DEGRADED

Containment Field

Gate: Filesystem access boundaries and write containment

Linked: RS-002, RS-003, RS-018 | Hooks: PyHarness, Reviewer, Git/CI

RS-002/003 containment enforced — outside-root writes blocked. RS-018 not tested yet.

S4STANDBY

Memory Field

Gate: Memory write authorization and durability

Linked: RS-013, RS-014 | Hooks: PyHarness, Memory/Registry, Reviewer

Memory backends exist but no unified reactor health probe.

S5STANDBY

Goal-Orchestration Field

Gate: Goal integrity and execution alignment

Hooks: Goal, PyHarness, Reviewer

Goal Harness defined doctrinally but not implemented as automation plane.

S6STANDBY

Architecture Cognition Field

Gate: Architecture consistency and mutation control

Hooks: Goal, PyHarness, Reviewer, Memory/Registry

Architecture cognition is doctrinal. No automated drift detection.

S7DEGRADED

Proof/Verification Field

Gate: Proof generation and independent verification

Linked: RS-019 | Hooks: Reviewer, PyHarness, Goal, Memory/Registry

Evidence layer expanded: RS-006/007/008/009/010 capture operational.

S8DEGRADED

Observability Field

Gate: Full execution traceability and anomaly detection

Linked: RS-006, RS-007, RS-008 | Hooks: PyHarness, Reviewer, Git/CI

RS-006-010 telemetry + git evidence captured. 10/20 RS observable.

S9STANDBY

Recovery Field

Gate: Failure detection and automated recovery

Linked: RS-020 | Hooks: PyHarness, Reviewer

Basic watchdog exists for gateway but no systematic recovery field.

S10STANDBY

Extension Ecology

Gate: Extension safety and compatibility

Hooks: PyHarness, Provider Pack, Git/CI

Extension ecology is architectural vision. No sandbox or isolation exists.

S11STANDBY

Human Command Layer

Gate: Human override, approval gates, and command authority

Hooks: Goal, PyHarness, Reviewer, Memory/Registry

Human command layer is through chat platforms. No formal approval gate system.

Provider Pack Warning

Provider packs are adapter exports, not source-of-truth architecture. No provider pack is implemented in this pass. Provider packs are future compiled exports of Source doctrine into Claude Code, Codex, Gemini CLI, Cursor, and similar tools. They are circuit breakers and adapters — the PyHarness remains the master enforcement plane.

Known Gaps

Unimplemented hook planes — all 6 planes are doctrinal only
Provider packs — not implemented, future adapter exports
Higher S-families (S0,S5,S6,S10,S11) — planned, not implemented
Provider packs — future-only
Independent reviewer loop — not implemented
Full proof coverage — no automated proof generation pipeline
Dynamic dashboard wiring — pages are static HTML; no live data binding
External memory/registry bridges — no reactor-integrated registry update pipeline
No automated health probes for any S-family
No containment enforcement (S3) beyond built-in path guards
No goal-orchestration automation (S5) — Goal Harness is doctrinal only
No architecture drift detection (S6) — manual review only
No systematic recovery field (S9) — basic watchdog only
