Objective

Complete the mandatory security/authorization/constraint-impact gate before Native Kanban/SOT schema implementation begins.

Scope

Documentation and test-plan analysis only. No runtime, schema, migration, API, or deployment edits.

Required analysis

  • Cross-workspace owners, principals, evidence, and project hierarchy
  • Active membership and service-token boundaries
  • Stale/forged public health and transaction-local write proof
  • Assignment/approval forgery and monotonic fencing
  • Change-proposal abuse and proposal/audit event binding
  • Immutable audit retention and break-glass boundaries
  • PostgreSQL and Valkey outage/failure semantics
  • Required negative tests and schema/API constraint impacts

Acceptance criteria

  • Threat/authorization matrix maps every risk to frozen contract controls and required evidence.
  • Every schema/API/test impact is explicit.
  • No unresolved schema-impact finding remains before KBN-100 release.
  • Independent SecReview passes.
  • PR squash-merges with terminal-green Mosaic CI.

Depends on merged canon PR #752. Blocks KBN-100.
