W3 — Comparative Registry (Z5↔Z5)

SYSTEM: World Education OS
PAGE: W3 — Comparative Registry (City↔City)
ZOOM: Z5↔Z5
REFERENCE: CivOS (P0–P3, Z0–Z7)
PURPOSE:
  Provide a machine-readable directory of comparative pages,
  each exposing:
    - dominant contrast signature
    - mapped global failure archetypes (GF*)
    - exportable repair mechanisms (GR*)

REGISTRY RULES (LOCK):
  - Every comparative must link to both city instance pages
  - Every comparative must include: crosswalk + traces + exportable repairs
  - No rankings; only mechanism contrasts + exportable fixes

COMPARATIVE COMPLIANCE:
  A comparative page is "valid" only if it contains:
    - pipeline alignment map
    - comparative scoreboard dimensions
    - failure mode crosswalk
    - shared sensor pack + calibration requirement
    - exportable repairs A→B and B→A
    - failure trace + repair trace

PRIMARY PURPOSE:
  Store comparative entries that:
    - use shared sensors (P-S* + G-M*)
    - identify contrast tags (mechanism differences)
    - export/import GR repair sets with proof requirements

W3 LOCK:
  No comparative is valid without:
    - shared sensor basis (P-S* + G-M*)
    - explicit dominant GF cluster
    - explicit export/import GR sets
    - proof requirements (which metrics must change)

    - G-M3 repair latency decreases pre-ramp

    GF3 compression exceeds buffers → GF6 timed collapse →

LOCK:
  W3 is the global registry of mechanism comparisons.
  Comparatives are the adoption accelerators:
    they force shared vocabulary, shared sensors, and exportable repairs.
  This is how “World Education” becomes a lattice, not an argument.
