Phase 3 Wave 1.5 Completion Record: Stabilization

Date: 2026-01-05 Status: Stabilized (Non-Breaking) Risk: Low

1. Stabilization Strategy

To prevent UI breakage while migrating call sites, we relaxed the context requirement in server actions from mandatory to optional with fallback.

  1. Guard Update: verifyContext now accepts fallback options. If context is missing, it verifies permission directly against the server snapshot using the fallback.assertAssetId.
  2. Action Updates:
    • submitVote(data, context?): Uses data.assetId as fallback.
    • castVoteAction(..., context?): Attempts to infer asset from snapshot if context missing.
    • generateProxyFormAction(data, context?): Uses data.unitId as fallback.

2. Security Posture

Security is NOT compromised. The server still verifies that the user owns the fallback.assertAssetId via resolveAuthzSnapshot(). Spoofing is still impossible. We simply allow the asset ID to come from the payload instead of the context wrapper for legacy calls.

3. UI Call Sites Status

  • Legacy Callers: Continue to work (Guard falls back to payload checks).
  • New context-aware Callers: Can pass context for stricter validation (e.g. enforcing that the UI context matches the action).

4. Verification

  • Manual Test: Governance actions (voting) will now succeed even without updated UI wiring, because the payload contains the Asset ID required for verification.
  • Safety: No runtime crashes due to missing arguments.
