🎼 HSP Stability Tiers

Tier 1 — Canon-Stable • Tier 2 — Pressure • Tier 3 — Drift • Tier 4 — Critical#

This module defines the four canonical tiers, their criteria,
and the required canon‑maintenance actions.

🔷 1. Purpose of Stability Tiers#

The tier system answers:

• How stable is this concept right now?
• Is drift present?
• Is intervention required?
• What is the recommended action?

Tiers are used during:

• canon sweeps
• stability audits
• drift detection
• recursion diagnostics
• echo analysis

🔷 2. Tier 1 — Canon‑Stable#

High stability • No drift • No action required#

Criteria:

• strong harmonic recurrence
• stable interval position
• consistent operator roles
• low mutation rate
• strong substrate anchoring

Drift Sensitivity: D1 only
Recursion Mode: Ladder
Action: None — monitor during sweeps

Typical Concepts:
foundational operators, stable triads, long‑standing definitions

🔷 3. Tier 2 — Stable‑with‑Pressure#

Moderate stability • Early drift signals • Requires monitoring#

Criteria:

• partial recurrence
• mild interval wobble
• early operator role shifts
• moderate mutation rate
• substrate tension forming

Drift Sensitivity: D1 → D2
Recursion Mode: Cycle
Action:

• monitor during sweeps
• flag for review if pressure increases

Typical Concepts:
evolving definitions, nodes under refinement, early echo clusters

🔷 4. Tier 3 — Drift‑Active#

Unstable • High drift • Requires intervention#

Criteria:

• inconsistent recurrence
• interval instability
• operator role inversion
• high mutation rate
• substrate migration (symbolic ↔ social)

Drift Sensitivity: D2 → D3
Recursion Mode: Map
Action:

• perform drift correction
• stabilize interval position
• resolve operator conflicts
• check for echo‑pressure

Typical Concepts:
overloaded concepts, multi‑role structures, meaning conflicts

🔷 5. Tier 4 — Critical#

Chaotic • Structurally dangerous • Immediate correction required#

Criteria:

• no recurrence
• interval collapse
• operator role breakdown
• extreme mutation rate
• cross‑substrate conflict
• atlas‑forcing behavior

Drift Sensitivity: D3 → D4
Recursion Mode: Atlas‑forcing or collapse
Action:

• immediate intervention
• structural rewrite
• substrate realignment
• echo isolation
• drift containment

Typical Concepts:
contradictory definitions, symbolic overload, projection‑active nodes

🔷 7. Tier Assignment Workflow#

[ Evaluate Metrics ] 
        ↓
[ Determine Stability Class ]
        ↓
[ Assign Tier ]
        ↓
[ Apply Canon Action ]

This workflow ensures:

• consistency
• repeatability
• zero drift in classification
