Changes from PR solid#134: - Fail-closed evaluation: unsupported condition types make the Authorization non-applicable (instead of being silently ignored) - Write-time validation: server SHOULD respond 422 when ACL contains unsupported condition types - Monotonicity: adding a condition can only restrict access, never expand - Migration safety: less-capable servers deny rather than expand access All other aspects of PR solid#134 are preserved: condition syntax, capability discovery, Client/Issuer conditions, conjunctive evaluation.
