<issue_to_address>
**issue:** The updated infrastructure documentation records Azure SQL as decommissioned, but repository documentation still identifies Azure SQL as the application data store, including the public privacy policy and the production Prisma client comment in `apps/api/Dockerfile`. Readers and compliance reviewers receive contradictory statements about where application data is stored.
**Suggested fix:** Update the remaining Azure SQL references that describe production storage, while preserving references that specifically document isolated preview behavior or historical migrations.
</issue_to_address>
### Comment 2
<location path="docs/neon-cutover-292.md" line_range="10" />
<code_context>
+1. **Neon CLI** (`pnpm exec neon connection-string`) for project `round-union-05852948` / branch `production` / database `neondb`:
+ - Pooled URL → Key Vault `database-url`
+ - Direct URL → Key Vault `database-url-unpooled`
+2. Prior Azure SQL `database-url` value saved as Key Vault `database-url-rollback-azure-sql` (soft rollback window; purge when confident).
+3. `./infra/migrate-db.sh` — schema already up to date (`20260828110000_init_postgresql`).
+4. Seeded `pillar/tenant/owner` + `pillar/tenant/settings` via `packages/db/scripts/seed.mjs` against Neon (`@prisma/client`).
</code_context>
<issue_to_address>
**issue (broader_impact):** The run record calls `database-url-rollback-azure-sql` a soft rollback mechanism even though the Azure SQL database and server were deleted immediately afterward, so restoring that secret cannot roll the API back to a functioning database.
**Triggers:** When the Neon deployment needs to be rolled back after the Azure SQL deletion.
**Suggested fix:** Either retain a live Azure rollback target for the stated window or describe this secret as historical backup data rather than an executable rollback path, and document the actual recovery procedure.
```suggestion
2. Prior Azure SQL `database-url` value saved as historical backup data in Key Vault `database-url-rollback-azure-sql`; it is not an executable rollback path because the Azure SQL database and server were deleted. Recovery requires provisioning a new Azure SQL target, restoring the database from an independent backup, updating Key Vault `database-url`, and redeploying the API.

🟡 Changes recommended
infra/main.bicep was modified but the repo convention requires regenerating and committing infra/main.json alongside any Bicep change to keep templates in sync.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
Documents the completed production cutover of the API database to Neon PostgreSQL and the decommissioning of the legacy Azure SQL Server resources, aligning infra docs and guidance with the new operational state.
Changes:
- Updated setup/infra documentation to reflect that Azure SQL has been removed as part of the #292 cutover.
- Recorded the cutover runbook/evidence (KV secret updates, migrate/seed, verification checks) in a new
docs/neon-cutover-292.md. - Adjusted infra guidance/comments to point readers at the completed cutover record.
File summaries
| File | Description |
|---|---|
| SETUP.md | Updates the “Provisioned” table note to reflect Azure SQL removal after the Neon cutover. |
| infra/README.md | Updates infra documentation to state legacy Azure SQL resources/secrets were removed and links to the cutover record. |
| infra/main.bicep | Updates inline comments about the Azure SQL decommission status post-cutover. |
| infra/deploy.sh | Updates “Next steps” output to reference the cutover record doc. |
| docs/neon-cutover-292.md | Adds a run record documenting the Neon cutover, Azure SQL decommission, verification, and follow-ups. |
Review details
Suppressed comments (1)
infra/README.md:240
- This line references "#292" but doesn’t link it; linking makes it easier to jump to the cutover record and avoids ambiguity about whether it’s an issue or PR number.
App Service continues to resolve `DATABASE_URL` from `@Microsoft.KeyVault(.../secrets/database-url/)`. Azure SQL server/DB and `sql-admin-password` were removed in the #292 cutover (see [`docs/neon-cutover-292.md`](../docs/neon-cutover-292.md)).
