Found in the Windows VM re-test.
- A CA-flagged server certificate (common with a plain openssl self-signed
cert) produced an installer package with no pin at all, so agent 1.20
refused the server. The package now always carries the SPKI pin of the
certificate PCs receive; the CA flag only skips the trusted-root import.
When an uploaded CA-flagged certificate differs from the server's own, both
pins are included. The build response carries X-ShopDB-Build-Warning and the
installer logs what older agents need.
- Pins written into appsettings.json by the installer were merged with the
registry, so removing a pin from HKLM never took effect. When the ServerPins
value exists in the registry it is now authoritative, even when empty;
appsettings pins apply only when it is absent. Set-ShopDBServerPins.ps1
-Clear deletes the value; new -None writes an empty value (no pins).
- A script or package download sent with a credential revoked moments earlier
got 401 CREDENTIAL_INVALID and failed the command. The agent now retries that
download once with the shared key and records the fallback in the result.
Found in an end-to-end test on a Windows 11 VM against a self-signed server.
- Rollback: a 1.20 agent re-enrolls within a second of an un-enroll, so an
older agent pushed afterwards arrived on an enrolled PC and was refused.
Revoke now takes {"blockreenroll": true, "reason": ...}; a blocked PC is
never issued a credential and keeps working on the shared key until
POST .../assets/<assetid>/allow-reenroll. The Enrollment page offers the
block when un-enrolling and shows blocked PCs with an allow button.
- First upgrade of old agents: agents before 1.20 check the server
certificate when downloading the upgrade, so a store wave failed on PCs that
do not trust a self-signed server while the Migration tab said ready. A
failed download now marks the PC blocked with "server certificate not
trusted by this PC". New Install-ShopDBServerCertificate.ps1 (GE-Enforce,
SYSTEM) adds a non-CA server certificate to the trusted roots after checking
its thumbprint; the server certificate page offers a .cer download and the
SHA-1 thumbprint.
- The generated installer writes ServerPins (with an optional next pin for a
planned rotation), can leave the shared key out so the PC waits for
approval, never touches an existing credential, and skips the trusted-root
import for a CA certificate.
- The agent re-reads server pins about every 60 seconds and recycles pooled
connections within 2 minutes, so a pin change needs no restart.
- An alert can only be acknowledged by a PC it targets.
- A wave no longer counts a PC as failed after a later wave upgraded it.
- The scripts report a pin mismatch only when the pin really is missing, and
otherwise log the real error.
- Runbook: trust step before the first wave, rollback order, pin re-read,
verifying the pin against the live URL; agent contract updated.
- Settings > Endpoints > Enrollment. Migration tab: readiness counts and
progress, each PC's state with the reasons it is blocked, "Upgrade
selected" and "Upgrade next 25", and live wave progress. Credentials tab:
enrolled PCs with revoke, pending requests with approve and reject, and the
shared key and auto-enroll switches. Turning the shared key off asks for
confirmation and shows how many PCs are not enrolled.
- The server certificate page shows the SPKI pin to put in the GE-Enforce
pin entry.
- The agent upgrade script and the asset and printer reporters send the PC's
credential when it has one (over https, only to the issuing server), fall
back to the shared key, check server pins, and log refusals clearly.
- New Set-ShopDBServerPins.ps1 (GE-Enforce entry) and Get-ShopDBServerPin.ps1.
- AGENT-CONTRACT.md documents per-PC credentials; the rollout runbook covers
phases, gates, rollback, pin and wave entries, and every place the shared
key lives and how to clear it at cutover.
- Removed the 09-14 certificate design notes and dated session reports, and
two VM notes that carried a live collector key and advised plain http.
- Corrected the GE-Enforce collector note, which claimed a plain registry
token is protected by ACL.
