Found in the Windows VM check.
- The agent upgrade script wrapped Get-ShopDbServerPins in @(), which turned
several registry pins into one joined string. During a certificate rotation
the upgrade download would have refused the rotated server. It also merged
appsettings pins with the registry; it now follows the agent's rule: when the
ServerPins value exists, even empty, the registry owns the list. The shared
pin block in the upgrade script and both reporters gains
Test-ShopDbServerPinsValue.
- A key-less package installed over an enrolled PC printed both "existing
enrolled credential found; kept as is" and "This PC will request
enrollment". The enrollment notices now print only when no credential exists.
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.
Both agent loops made their first request the instant the service
started, and the service is installed start=auto - so a patch reboot put
the whole fleet on the wire together, twice per machine (a telemetry
report and a command poll). The existing jitterseconds does not help: it
spreads the gap between runs, not first contact.
Measured on a 700-endpoint burst: simultaneous arrival drove TLS
handshakes to 1482ms worst case and pinned CPU at 305% while the
database sat idle at 3 active queries. Spreading the same arrivals over
30s cut worst-case handshake to 63.7ms with no server-side change. The
server was never the constraint; simultaneity was. Raising the
SQLAlchemy pool was tried and rejected - it moved the queue from
SQLAlchemy into MySQL without adding throughput.
StartupJitter is shared by both workers so the clamp and the
randomisation cannot drift apart between them. Randomised in
milliseconds rather than whole seconds because a 30s window at second
granularity re-clumps a large fleet into 30 buckets of simultaneous
arrivals - the same pile-up in miniature. Clamped to 300s and warned
about when out of range: the command channel is how an operator would
correct a bad value, so an unbounded delay would remove the means of
recovery.
The cost is up to startupjitterseconds of extra latency before a
rebooted endpoint picks up a queued command, on top of a reboot the
machine was already unreachable for. The once-only console switch
bypasses the delay entirely, so smoke tests stay instant.
Agent 1.12.0. Minor because the appsettings schema gains a key; packages
without it fall back to the AgentConfig default. The shipped installer
template in siteagent.py carries the new key, so the containers need
rolling before newly built packages pick it up.
Corporate Tools tab on PC Details, gated by endpoints.deploy and liveness.
Starts already-registered scheduled tasks; the agent's ScheduledTaskPolicy
allowlist remains the authority on what may actually run.
Dell Command | Update split into two actions (Scan, Apply Updates) because
they have very different consequences. Apply Updates carries a persistent
breakglass warning in the card naming Tanium as the primary update utility,
rendered between the row title and description so it is visible at all times
rather than only in the confirm dialog. Destructive actions keep the typed
RUN confirmation.
Fix scheduledtask_run being stripped by Configuration Policy: the
intersection in ALLOWED_ACTIONS_FOR dropped it on any endpoint whose
effective policy was non-empty, so every Corporate Tools click failed with
"not permitted by policy" regardless of the caller's role. Corporate tools
are role-gated only, via POLICY_EXEMPT_ACTIONS; policy keeps authority over
monitors and service/process primitives.
Fix blank PC Details page: watch(detailtabs) evaluates its source during
setup and read canDeploy before its const declaration, throwing a TDZ
ReferenceError that aborted setup with no API request made.
Mapped-drive refresh moves to the tray. SYSTEM cannot probe user-scoped
drives, so the service requests a re-probe over a named event and waits for
the spool collectedat stamp to advance before collecting. The probe task is
registered as a ShopFloor user principal; the Users-group principal remains
only as a degraded fallback since a group member cannot start it.
Mapped drives reported Unavailable on endpoints where the operator could
see them fine. The data path was intact; the collection was running under
the wrong token. Mapped drives are per logon token, so an elevated probe
enumerates a different drive table than the interactive user.
Collection:
- Pin the user-context spool path so the probe and service agree on one
location, and persist/overwrite it instead of deleting on read.
- Refuse to collect while elevated (exit code 2) rather than emitting a
confident wrong answer, and stamp elevated/username on the spool.
- Reject spools stamped elevated or from an unexpected account on read,
so an admin run cannot masquerade as valid.
- Log netuse/smbmapping/userlistener counts so each run leaves evidence
of what it actually saw.
Install and launch context:
- Move collection to a 'ShopDB user-context probe' scheduled task under
S-1-5-32-545 at RunLevel Limited, the only mechanism that reliably runs
in the operator's own session. Verify registration and record it in the
install ledger.
- Stop starting the tray as a child of the elevated installer; explorer.exe
de-elevates without changing ACCOUNT, so an admin install produced an
admin tray. The Run key only fires at logon, which left the tray dead on
a machine already signed in, so add a transient 'ShopDB tray first launch'
task that starts it once in the existing session and unregisters itself.
- Hide the console window during --collect-usercontext. The agent is a
console exe; the tray used to mask this with CreateNoWindow, but the
scheduled task invokes it directly and flashed a window every cycle.
Installer edits are in _install_script() in plugins/endpoints/api/siteagent.py,
which generates the install.ps1 that actually ships. The standalone
agent/installer/install-shopdbagent.ps1 was never shipped once the package
moved to the UI builder and is deleted here to stop the divergence that
caused an earlier fix to land in a file no endpoint ever ran.
Versions: agent 1.10.1, tray 1.3.0. These share the pinned spool path and
must be deployed together.
Pre-existing test failures unrelated to this work (8, identical on a clean
tree): docs publishable/versions, plugin contract symlink scan, import
guard tamper check, security headers upload sandbox, and three endpoint
timestamp tests.
Append the staged agent version to the site-agent ZIP download name so DT operators see the build at a glance; the exe name inside the ZIP is unchanged so install.ps1 is untouched. Read the versioned name from Content-Disposition on the client. Group agent/tray binary management under a collapsed 'Upload New/Legacy Agents' section and default the key explainers to collapsed.
Restructure the agent and tray binary blocks around an auto-detected current-release upload plus a separate legacy/rollback upload that stages a version without seizing current. Order staged versions by version number for the active-version dropdown, add a PE version detect route, and drop stale dev-status tags and manual-staging copy.
Add per-version staging, retention (keep 3), and upload/rollback routes for shopdbagent.exe and the tray exe. Keep upload under endpoints.agentpackage and declare a distinct endpoints.agentupdate permission for the future live-push pipe so app-deploy rights never imply SYSTEM agent replacement.
Bring in the natural-key import fix, Metrics->Monitors rename, PC detail tabbing and panel groups, guest search grants, and the 2026-08-30 security fixes. Reconcile endpoint packaging/installer, migrations, contract version, and tests; keep the delivery uninstaller and 6-step installer alongside main's permission-based RBAC and pin-drift protection.
install.ps1 carries the live collector key, so it must not linger on the endpoint. Before removing it, the installer now confirms the service reached Running (with retries) and that the tray process is up, failing loudly and keeping install.ps1 in place if the service never starts. Once healthy, it archives the uninstaller, appsettings, README, and cert into C:\ProgramData\ShopDB\EndpointAgent, deletes install.ps1, and prints the uninstaller path.
The tray draws its icon at runtime and has no embedded Win32 icon, so shortcuts showed the generic exe icon. Add a headless --export-icon mode that reuses the same GDI+ drawing to write an .ico, and have install.ps1 export it and set the shortcut IconLocation. Keeps one source of brand truth with no checked-in binary.
The site-agent bundle now includes uninstall-shopdbagent.ps1 so operators can cleanly remove an install without hunting for the repo script. The packaging route reads it from scripts/, which was not mounted into the api container, so add a read-only ./scripts:/app/scripts mount (recreate the container to apply).
install.ps1 now registers the tray to autostart for every user via the HKLM Run value ShopDbEndpointTray, adds an All-Users 'ShopDB Agent' Start Menu shortcut for manual relaunch, and launches the tray once post-install. The tray enforces a single instance via a Global named mutex so repeated launches no longer stack duplicate icons. The uninstaller removes the Start Menu shortcut alongside the existing Run key and credential cleanup.
Ben Baker's installed-software collection, software delivery (run_script and
update_app), agentless adoption tool and command-queue hardening, with his
authorship preserved.
Reviewed before promotion. Fixed: the endpoints plugin tests were never collected
by pytest, the SBOM snapshot table's key would exhaust on MySQL, ingest did not
truncate two columns strict MySQL would reject, and update_app's version branch
pinned a digest for a file that route never serves. Agent packaging moved off
require_role('admin') onto a new endpoints.agentpackage permission.
Contract 0.27.0. Full suite 2231, frontend 314.
Adds the two delivery actions to the endpoints command allowlist, each gated on a new endpoints.deploy permission ON TOP OF endpoints.command so pushing software is a heavier grant than a routine toggle. Enqueue validates update_app appversionid ownership and installer presence before queueing. New collector-authenticated download routes let the agent fetch installer packages and script bodies by digest rather than pre-staging them or sending bodies over the command wire. Wires the scriptsApi client, the siteagent generator routes, and a temporary dev-only Delivery test bench (view/route/nav) for exercising the path while the production UI is built.
