ZirOS v0.7.4

ZirOS v0.7.4

v0.7.4 is a repo-wide release cut that folds the flagship
private_claims_truth_and_settlement_subsystem into the main ZirOS release
line while updating the public installer surfaces to resolve against this
repository's GitHub releases.

Included in this release

• Flagship private_claims_truth_and_settlement_subsystem artifacts for
  property and casualty claims truth, selective-disclosure settlement, and
  Midnight-facing settlement validation.
• Strict HyperNova/Pasta proof-lane closure for the flagship claims subsystem,
  with truthful telemetry and subsystem completeness evidence.
• Runtime and backend fixes required to support the claims flagship lane,
  including corrected HyperNova/Nova field truth surfaces and larger proof
  encode buffers for large flagship artifacts.
• Updated support, product, provenance, and operator readiness truth surfaces
  for v0.7.4.
• Repo-native npm installer defaults and installer manifest URLs that target the
  AnubisQuantumCipher/ziros release line.

Honesty boundary

• The flagship claims subsystem is validated on the current host with
  backend_selected = hypernova.
• The recorded host telemetry for the flagship claims run is CPU-only on this
  machine; the release does not claim Metal or GPU execution where telemetry did
  not prove it.
• Midnight-facing validation in this release is compile/prepare-grade evidence,
  not a claim of live deploy on-chain finality.
• The task-scoped claims release
  private-claims-truth-flagship-20260408 remains published separately and is
  preserved as its own artifact tranche.
