Document Organizations matrix escalation-axis re-derivation

[jgulyash]

Summary

This PR adds the written re-derivation of the Organizations matrix's escalation scoring axes, closing a documentation gap identified in the escalation_rubric. The Organizations matrix was scored at V1.5 without a preserved written convention for its axis semantics, unlike the Infrastructure matrix. This change documents the post-hoc re-derivation ratified under Ruling 1, Option A (2026-07-27).

Key Changes

• Added docs/methodology/DESIGN-b5-org-escalation-scoring.md — A comprehensive design document that:

  • Establishes the institutional harm model as the Organizations matrix's semantic foundation
  • Re-derives all four escalation axes (impact_potential, blast_radius_potential, recoverability_inverse, detectability) with explicit tier definitions anchored to institutional consequences rather than physical casualty counts
  • Elects stakeholder/population scope of institutional harm as the blast_radius_potential semantics (Ruling 1, Option A)
  • Clarifies that no severity_floor applies to the Organizations matrix (recorded at B5 merge with zero floors across 240 indicators)
  • Validates the re-derived semantics against the shipped 240-indicator population, confirming monotone growth across lifecycle phases and correct tier placement
  • Explicitly routes Phase-4 trace-behavior classification to the pending aftermath blast reconciliation rather than pre-ratifying it
  • Documents the audience-vs-victims distinction to guard against misreading narrative reach as stakeholder harm

• Updated CHANGELOG.md — Added entry under [Unreleased] documenting the new design document and its scope

• Updated docs/methodology/README.md — Added reference to the new design document in the methodology index

Notable Implementation Details

• The document is explicitly authored post-hoc and states so; it does not silently ratify disagreements between authored values and the re-derived semantics, instead routing those to the aftermath reconciliation pass
• The escalation formula, thresholds, and detectability flip remain unchanged; only axis semantics and blast_radius base rates are re-anchored
• Validation confirms the 240-indicator population (weight range 2.69–7.32, bands: 105 medium / 123 high / 12 critical) conforms to the re-derived tiers
• The seam section explicitly defers Phase-4 trace-behavior scope classification to a future reconciliation pass, maintaining clarity about what this document settles vs. what it routes onward
