Add the NVCT task health column for fresh and upgraded keyspaces. Wait for native transport and usable superuser authentication before initialization, then consume migration image 0.17.1 through Cassandra chart 0.20.2. Fixes #1098 Signed-off-by: Stephanie Baum <sbaum@nvidia.com>

📝 WalkthroughWalkthroughThe change adds Cassandra startup checks before password configuration, updates Cassandra deployment versions, and adds the ChangesCassandra compatibility updates
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The Cassandra initialization hook now waits for transport and authentication readiness, but its authentication retry loop can extend startup beyond the configured initialization deadline when readiness is delayed. This is a bounded operational risk that should be fixed or explicitly accepted by the owner. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Keep authentication retries within the initialization deadline.
initialize_db sets a 600-second deadline. wait_for_superuser_authentication replaces it with a new 120-second deadline. If native transport becomes ready near the overall deadline, initialization can wait for an additional 120 seconds. Pass the overall deadline into this function and use the earlier deadline.
Proposed fix
wait_for_superuser_authentication() {
local pod="$1"
- local end=$((SECONDS + 120))
+ local deadline="$2"
+ local auth_end=$((SECONDS + 120))
+ if [ "${auth_end}" -gt "${deadline}" ]; then
+ auth_end="${deadline}"

TL;DR
Makes the packaged Cassandra schema and initialization hook compatible with
current NVCT releases.
Additional Details
Current NVCT writes
tasks_v2.health, but the self-managed schema does notdefine that column. Fresh installs now include it, and existing keyspaces
receive an additive, idempotent migration.
Cassandra pod readiness can also precede CQL native transport and bootstrap
superuser authentication. The initialization hook now waits for both states
before deciding whether password reconciliation is required.
The migration image moves to
0.17.1, the Cassandra chart release moves to0.20.2, and the self-managed stack consumes that chart.For the Reviewer
Review the fresh-install schema and upgrade migration together. The hook retry
test covers delayed native transport and delayed authentication without logging
credentials.
Customer Release Notes
Self-managed Cassandra supports current NVCT task records and handles normal
startup readiness races.
Plan Summary
Adds one nullable Cassandra column and bounded readiness checks to the existing
initialization job. No Kubernetes resources are added or removed.
Usage
Use the existing self-managed install or upgrade workflow.
For QA

consumed by the self-managed stack.
