 - Simplicity first: minimal, targeted changes. No temporary fixes — find the root cause.
 - Where architecture is flawed, state is duplicated, or patterns are inconsistent, propose and implement the structural fix. Ask what a perfectionist reviewer would reject, and fix that too.
 - On non-trivial changes, ask whether there is a more elegant way before presenting. Skip it for simple fixes — don't over-engineer.
+- Reuse before you write: search for an existing helper by what it does (its key call, literal or regex), not by a guessed name. Web helpers live in `lib/` (route-only ones in a `lib/` beside the route), backend helpers in `Functions/Helpers/`.
+- Dead and copied code is gated: the .NET build fails on unused private members and parameters (`.editorconfig`), `npm run knip` covers web and MCP, and `npm run dup` in `tools/quality` fails on new clones. CI only reports, so run them before calling a change done.
 - English for code comments and everything that carries knowledge.

+.SYNOPSIS
+    The one place the workflows and the release scripts take their hosts from.
+
+.DESCRIPTION
+    CI's member of the URL registry (Shared Constants.cs, web lib/config.ts, MCP src/config.ts):
+    every own host the workflows and the .github/scripts helpers talk to, plus the Authenticode
+    timestamp server, is defined here once. Assert-HostsFromRegistry.ps1 (Workflow gates) fails
+    on any of these hosts spelled out elsewhere under .github/.
+
+    The storage URLs derive from the account name, so blob and table can never point at two
+    different accounts.
+
+    A file in the repository rather than a GitHub variable: the helpers read it themselves, so
+    they behave the same in every job and in a local run, and bearer tokens are sent to these
+    URLs -- where a token goes stays a reviewed line in git.
+
+.PARAMETER ExportToGitHubEnv

+.SYNOPSIS
+    Checks the bootstrap's folders against a real standard user.
+
+.DESCRIPTION
+    Creates a temporary local standard user and, with that user's token, tries what any local user
+    on an enrolling device could try against the folders the loader and the installer create:
+    write, change, rename and delete files, add entries, move or delete the folder. Every attempt
+    must be denied. Folders the user creates first, or entries the user plants in an unprotected
+    agent folder of an older installer, must make the installer stop instead of installing into
+    them. A control attempt proves the user can write where users may.
+
+    The folders come from the installer's own functions, in a scratch copy of ProgramData that
+    carries the real ProgramData permissions.
+
+    CI only (bootstrap-script-gates.yml): it needs an elevated runner, and it creates a local
+    account and removes it again.

 <#
 .SYNOPSIS
-    Stage 1 of the Autopilot Monitor bootstrap: fetches the current installer and runs it.
+    Downloads the current Autopilot Monitor installer and runs it.
 
 .DESCRIPTION
-    This is the file an administrator assigns in Intune, and the same file the bootstrap MSI
-    installs and runs -- one implementation for both delivery channels; the MSI is only the
-    packaging. It carries no enrollment logic at all: it downloads the published
-    Install-AutopilotMonitor.ps1, proves that it was signed by Autopilot Monitor, and runs it
-    in this process.
+    Assign this script in Intune once; the bootstrap MSI runs the same script. It downloads
+    Install-AutopilotMonitor.ps1 from download.autopilotmonitor.com and runs it only when the
+    file carries a valid signature from glueckkanja AG and is installer version 2.7 or later.
+    Because the installer is fetched on every run, this script does not need replacing when
+    the installer changes.
 
-    Why two stages: the installer holds every guard, relax rule and download path, and those
-    change. Whoever assigns the installer directly has to replace their Intune copy each
-    time; whoever assigns this loader never does, because the part that changes lives on the
-    server. Assigning the installer directly stays supported and unchanged.
+    The download and the log go into %ProgramData%\AutopilotMonitor-Loader-<random>, which only
+    SYSTEM and administrators can change. The loader keeps the downloaded file open from the
+    check to the end of the run, so what it checked is what runs. After a successful run the
+    folder is removed; after a failure it keeps the log for diagnosis, and a later installer
+    run removes it.
 
-    This file is deliberately boring. It is the one piece that cannot be fixed remotely, so
-    it does the least it can: download, verify, invoke, log.
+    The exit code is always 0, so the loader never fails enrollment. Without SYSTEM or
+    administrator rights it stops with an error and changes nothing.
 
-    Verification is by Authenticode publisher, not by hash. A hash oracle would have to be
-    fetched from the same host as the script itself, so it could not survive a compromise of
-    that host, while the expected publisher below travels with this file. It pins the
-    certificate SUBJECT and not a thumbprint, so a certificate renewal does not brick a
-    loader that is already deployed on devices.
-
-    Fail-soft: the loader always exits 0 and never throws into the caller. A device that
-    cannot reach the download endpoint is a device without monitoring, never a failed
-    enrollment step. Verification failures are the same: nothing runs, and the reason is in
-    the log. Refusing to execute unverified code as SYSTEM is the point of this file.
-
-    This file MUST remain pure ASCII (PS 5.1 reads BOM-less files as ANSI).
+    Any other arguments are passed to the installer, for example -MaxBootstrapWindowHours 24.
 
 .PARAMETER BootstrapUrl
-    Installer URL. Defaults to the published stable installer; the -Dev variant of this
-    loader is rendered from that default at publish time.
+    Installer to download. Default: the published installer.
 
 .PARAMETER LogFileName
-    Log file inside the agent log directory. The MSI channel passes bootstrap-msi.log so the
-    delivery channel stays visible in a diagnostics package; the diag tooling keys on these
-    names, so do not rename them.
-
-.PARAMETER BootstrapArguments
-    Everything else is passed through to the installer unchanged, so any parameter the
-    installer accepts can be set here without this file knowing about it.
-
-.EXAMPLE
-    .\Start-AutopilotMonitor.ps1
-
-.EXAMPLE
-    .\Start-AutopilotMonitor.ps1 -MaxBootstrapWindowHours 24
+    Name of the log file. Default: bootstrap-loader.log.

-    Runtime : Windows PowerShell 5.1, SYSTEM context, during Autopilot enrollment
-
-.CHANGELOG
-    2026-09-08  v1.2  Log the signer CN instead of the full EV subject; the full subject is
-                      logged only when the publisher is why a script was rejected.
-    2026-09-08  v1.1  Also used by the bootstrap MSI, which replaced its own copy of this
-                      logic; -LogFileName keeps the channel visible in diagnostics.
-    2026-09-08  v1.0  Initial version: two-stage bootstrap, publisher-pinned verification.
