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.
Mapped drives stopped reporting because the user-context path failed silently
in three separate places, and none of them left a trace to read back.
- Probe: launch via -EncodedCommand instead of staging a temp .ps1 and running
powershell.exe -File. A missing or quarantined script file fails BEFORE any
statement runs, so the script's own try/catch never sees it and the only
symptom is exit -196608.
- Spool: pin to the ShopFloor profile. Resolving it through WTSQueryUserToken
is privileged, endpoint protection blocks it, and on failure the tray
(writer) and service (reader) silently disagree about the path.
- Spool: consume after a successful parse, so a stopped tray cannot keep
re-reporting stale mapped drives as current. Unparseable files are left in
place for the next cycle.
- Logging: user-session components cannot write to Program Files or to the
SYSTEM-owned ProgramData log directory, and the file sink degrades to a
silent no-op when it cannot create its directory. Tray and probe now log to
C:\Users\ShopFloor\ShopDB\Logs, installs transcript to ProgramData, and the
sink records a SinkProblem instead of swallowing UnauthorizedAccessException.
- Installer: provision the operator spool/log directories with ShopFloor:Modify
before the tray first runs, and stop the transcript via trap so a throw
cannot orphan exactly the failed install worth reading.
- Upload cap 64 -> 128 MB: the self-contained tray publishes at ~69 MB and was
rejected on SIZE, but the size check returns before the PE is parsed, so the
operator only ever saw a version-detection failure.
AGENT-CONTRACT.md gains a normative section defining the three security
contexts, their log destinations, the fixed spool path and consume-on-read.
Agent 1.8.0 -> 1.8.1, tray 1.1.0 -> 1.1.1 so the deployed build is
identifiable from a log line.
Records why rebootreasons is not redundant with pendingreboot, why bootinfo carries two facts that must not be collapsed, and why defender is stored unsurfaced.
Also corrects the notes: pending file-rename was already being collected and OR-ed into pendingreboot, so the gap was that the stronger signal was flattened into the weaker one rather than missing. Records that the columns landed as 0015 because 0014 was taken by disk health earlier in this phase.
Records why there are two sources and why they are not reconciled, so the next person does not simplify the ATA SMART path back in and silently blind the fleet on NVMe hardware.
Also notes that diskhealth is per physical device and is not the same list as disks, and that a null predictfailure is unknown rather than healthy.
Curated events were re-read from the newest 25 entries per channel on every
collect, and the server appended whatever arrived. One real event was
therefore stored again on every cadence tick for as long as it stayed in
that window, so event counts measured how long a box had been up rather
than what had happened to it.
The agent now keeps a per-channel watermark of the last Windows event
record id it reported, persisted under ProgramData so a service restart
does not replay history, and sends eventrecordid with each event. The
server dedupes on (assetid, eventchannel, eventrecordid) behind a unique
index, so a replay from an older agent cannot double-store either.
Six inventory keys the agent had been sending all along - bios, disks,
domain, memory, osinfo, processor - were parsed, logged as unpersisted,
and dropped. They now have columns and are written on check-in, along
with user context, pending reboot, and the cpupercent/memorypercent/
idleseconds fields that were declared in the contract but always null.
Session-scoped data cannot be read from the agent's LocalSystem session 0
at all: mapped drives and user-owned listeners do not exist there. A probe
runs in the interactive user's session and hands results back through a
spool file. It is not yet producing output on a live endpoint; the column
and panel are in place and read empty until that is fixed.
Also bounds the user-context script wait. It was WaitForSingleObject with
INFINITE, so a hung script pinned the command worker permanently.
The agent already reported agentversion but the interactive tray app, which ships and updates independently, had no reported version. The agent now reads the tray exe file version and reports it as trayversion; EndpointState caches it (migration 0011) and the Fleet card surfaces it beside Agent. The tray csproj gains an explicit Version so the file version is stamped. Groundwork for per-PC version surfacing and push-update targeting.
Default fuzzy reconcile threshold to 0 and refuse merges when digit runs differ so numbered labels like Bay 311 never bind to Bay 310. Keep edit forms from clearing saved model fields when category filtering hides untyped rows. Includes in-progress computers policy and endpoints command feature work.
