Register-GEEnforce: use SHA-256 instead of MD5 for per-PC jitter offset
FIPS-enforced PCs (System cryptography GPO) reject non-approved algorithms at the .NET crypto API level. MD5 throws "This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms" on .Create(), which aborts Register-GEEnforce before the scheduled task is built. SHA-256 is FIPS 180-4 approved and its default .NET provider is validated, so SHA256.Create() works under FIPS mode. Functionally equivalent for the 0-4 minute modulo we need for jitter. Hit this live on the first production retrofit. Enforcer runtime files were copied and legacy tasks were unregistered, but the new task creation aborted. Rerunning Deploy-GEEnforce.ps1 is idempotent and recovers. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

Stage 2a: unified GE-Enforce framework + share-root mirror
Consolidates per-type enforcers (CMM, Keyence, Machine, Common, Acrobat)
into one dispatcher driven by pc-type.txt + site-config and a share-side
manifest layout. Same share is now the single source of truth for routine
software updates without re-imaging.
Runtime:
common/GE-Enforce.ps1 SYSTEM scheduled task. Reads
common/manifest.json plus optional
<pcType>/manifest.json and
<pcType-subType>/manifest.json.
Dispatches each entry through the lib.
Writes _outputs/logs/<hostname>/status.json
on the share after each cycle for fleet
monitoring.
common/Register-GEEnforce.ps1 Task registration. Triggers: AtLogOn +
every 5 min (jittered per-PC from
hostname hash) + daily at 05:45,
13:45, 21:45 EST shift windows.
Unregisters legacy per-type tasks on
install so the two coexist at most for
the duration of a single enforce cycle.
common/Deploy-GEEnforce.ps1 Retrofit helper for already-imaged PCs
(admin-run; copies runtime + registers
task + optional immediate trigger).
Library (common/lib/Install-FromManifest.ps1):
- New Type values: PS1, BAT, File, Registry, INF
- New DetectionMethod values: Always, MarkerFile, ValueMatches, pnputil
- TargetHostnames filter (exact + -like wildcards, ANDed with PCTypes)
- Schema version check (logs WARN on manifest newer than lib MAJOR)
- Auto-writes MarkerFile on successful one-shot PS1/BAT/CMD runs
- MSI log scan on failure surfaces meaningful install errors
- Lib version bumped 2.0 -> 2.1 for TargetHostnames
Observability:
common/monitor-fleet-status.py Scans _outputs/logs/*/status.json for
stale check-ins, failed scopes, and
version drift. Respects scope (dir-name),
PCTypes, and TargetHostnames filters so
entries excluded from a PC do not
false-flag as drift.
Regression harness:
common/test/ Parameterized VM harness + README
covering every action type plus
rollback, bad/missing SFLD creds, and
schema versioning.
Imaging integration:
Run-ShopfloorSetup.ps1 now stages GE-Enforce.ps1 and lib to
C:\Program Files\GE\Shopfloor\ and invokes Register-GEEnforce.ps1
at the end of setup. Legacy Register-CommonEnforce invocation is
kept for the transition; it and the legacy per-type enforcer files
are dead code once Register-GEEnforce runs and will be removed in a
dedicated cleanup pass.
Standard-Machine manifest:
eDNC entry bumped 6.4.3 -> 6.4.5. DetectionValue pinned to the
4-part FileVersion 6.4.5.0 verified against a fresh install in the
Win11 analyzer VM. UDC DetectionValue pinned to 1.0.34 (registry
stores 3-part for UDC; verified live).
scripts/mirror-from-gold.sh:
Restructured around share-root rsyncs (one pass per Samba share)
to close gaps in the prior per-subdir layout: winpeapps/_shared/
Applications (7.5 GB of Adobe + fonts + Java + Office + OpenText
+ printdrivers + wireless + Zscaler), additional winpeapps image
types, and enrollment flat-layout root files. Adds
--skip-clonezilla and --skip-reports.
Verified end-to-end in the Win11 analyzer VM:
- Every action Type and DetectionMethod round-tripped
- PCTypes filter (Oracle excluded on Shopfloor, Firefox included
on Shopfloor and DESKTOP-*, excluded elsewhere)
- TargetHostnames filter (exact, wildcard, no-match)
- Upgrade path: XML hash bump + fleet re-copy
- Rollback path: history-archive restore propagates via enforcer,
fleet converges back without per-PC intervention
- Status writeback + monitor script drift detection
- Graceful degradation on bad creds, missing creds, share
unreachable (all exit 0, log clearly, retry next cycle)
Not in this commit (follow-ups):
- Retire legacy per-type *-Enforce.ps1 files and simplify
09-Setup-*.ps1 scripts (coordinated multi-file cleanup)
- Stage 2b: InUseCheck close-and-reopen, ApplyMode gating,
UpdateWindow, .apply-now.txt sentinel, BITS pre-staging,
1618 mutex retry, PostInstallCheck, Uninstall action
- Management app (manifest CRUD + deploy + rollback + fleet view)
- ShopFloor autologon persistence bug (deferred for next imaging
attempt with live registry evidence)
