Run on a domain-joined PC. Exports every unexpired PESCO CA certificate from the Windows stores to one PEM bundle and copies it to docker-1 with scp (default target `~/packetstation/test/ca/pesco-ca.pem`). Use `-Remote` for another path and `-NoCopy` to only write the file. It warns on SHA-1 signed certificates; see docs/DEPLOY.md.
Run elevated on the SQL Server host behind vsql, in Windows PowerShell 5.1 or PowerShell 7. Requests a TLS certificate from PESCO-PSYLOCKE-CA with certreq the way SQL Server requires it (legacy Microsoft RSA SChannel Cryptographic Provider, KeySpec AT_KEYEXCHANGE, RSA 2048, SHA-256, Server Authentication, key usage 0xA0, SANs vsql.pesco.com, vsql and the host FQDN and short name). It installs it and validates it before anything is bound. The validation checks the key provider and KeySpec from the certificate's own key property, the key size, the signature, the dates, the EKU, and the SAN DNS names as whole names. It grants only the selected instances' service accounts read on the private key, then binds the thumbprint and reads it back.
-`-WhatIf` previews every step and changes nothing. `-Confirm` asks before each change. Declining enrollment or a key grant cancels the run with nothing bound (exit code 2).
-`-CerFile` continues a request that was pending. `-Thumbprint` binds a certificate already installed. `-Instances` limits the run (`DEV`, `MSSQLSERVER`). `-RestartInstances` restarts them and starts SQL Server Agent again if it ran.
- Each deployment writes a new `deploy-<time>.json` in `C:\ProgramData\PacketStation\vsql-cert` with the values it replaced. Instances already bound to the thumbprint are left alone and get no snapshot, so a rerun never hides the useful one. A pending request writes `request-<time>.json` with its request id.
-`-Rollback` restores the newest snapshot not yet rolled back, each instance on its own, verified by reading back, and records it in `rollback-<time>.json`. `-Snapshot` picks another. Failures are listed and the run exits with an error.
Tests: `scripts/tests/Request-VsqlServerCertificate.Tests.ps1` (Pester 5) fakes the host (instances, services, registry, machine store, certreq, icacls) and uses real throwaway certificates in `Cert:\CurrentUser\My`. Run it on both PowerShell versions:
