From c4aa37d990a4aac5397e2c1db7fe440f60ed5e23 Mon Sep 17 00:00:00 2001 From: Tofik Hasanov Date: Wed, 29 Jul 2026 07:08:48 -0400 Subject: [PATCH 1/2] fix(policy): capture and display policy signature timestamps MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Problem Customer reported needing policy acceptance records with date and time per employee for SOC 2 Type II audit. When checking the employee profile → Policies tab and Policy detail → Activity log, no signed dates were visible. The platform had no way to answer "when did employee X sign policy Y". ## Root cause Policy.signedBy stores only a flat array of member IDs with no timestamp captured at signature time. There is no separate signature audit table or any historical record of when acceptance occurred. The auditLog in the portal schema was commented out and never implemented. ## Fix Introduce a new PolicySignature table to record policyId, memberId, and signedAt timestamp for each policy acceptance. From this point forward, exact signature timestamps are captured when an employee accepts a policy. Existing signatures without timestamps remain as-is (no backfill of historical data). This makes the data we have explicit and honest old signatures show unsigned, new ones show the exact date and time. ## Explicitly NOT touched No attempt to backfill or invent timestamps for signatures that occurred before this change. The existing Policy.signedBy array is left as-is to avoid migration complexity and to avoid creating false audit records. ## Verification Added unit tests asserting that PolicySignature records are created with the correct timestamp when an employee signs a policy, and that signatures without timestamps return null.
