+# Directory diagnosis and recovery lab
+
+The `identity-directory-operations` module covers AD replication versus DFSR/SYSVOL, GPO applicability/precedence, exact delegation and single-object/GPO recovery. Its references route each diagnostic branch without broad repair commands. Ordinary Windows-host CI does **not** exercise a domain, GPO processing, AD object restore or SYSVOL recovery.
+
+## Required separate target
+
+Use an owner-approved disposable `.test` forest with two writable DCs and a domain member/canary on the chosen Server build. Isolate its virtual network from production, disable external trusts and production credential reuse, reserve an independent console/recovery identity, and record exact domain, NTDS and VM identities. Domain creation, Recycle Bin enablement, roles, networking, membership and reboot need their own approved provisioning plan; this repository does not discover or repurpose arbitrary VMs. Test each supported release/topology before claiming it.
+
+Run reviewed source on a protected management host with Windows PowerShell 5.1, AD/GroupPolicy RSAT and a scoped lab management session. Read-only access does not grant mutation authority. Protected execution in platform 0.15 requires an administrator-registered immutable typed task, external signed grant and exact R4 admission; no AD recovery task is shipped or configured here. Local operation_gate results, unsigned requests and owner-run flags are planning-only. Do not give a public PR a domain credential or persistent privileged runner. Run integration manually against the reviewed commit in the isolated lab; publish only redacted receipt/digests. Keep raw GP reports, backup contents and principal/topology data in access-controlled storage.
+
+## Read-only preflight and planned recovery fixtures
+
+The source-only `tests/check_identity_directory_lab.ps1` requires fixtures prepared by the lab owner:
+
+- One dedicated OU and one disabled disposable user directly inside it, both with description `DevopsSkillDisposable:<lab_id>`. The user has no non-primary memberships, SID history, service principal names or protected flags, and primary group 513. Enable Recycle Bin **before** creating/deleting the fixture under its separate approved plan.
+- One dedicated, entirely **unlinked** nondefault GPO with the same description and a String registry setting `HKLM\Software\Policies\DevopsSkillLab`, value name `RecoveryMarker`, value equal to `<lab_id>`. This avoids applying the recovery-test mutation to clients. Do not attach scripts, secrets or production settings to this fixture.
+- An existing local backup parent protected from other writers, with enough space. The child `<backup_parent>/<lab_id>` must not exist. The read-only preflight creates nothing. The external owner drill retains its exact fresh `Backup-GPO` instance and does not automatically delete backups or the OU/GPO/user.
+
+Create a private JSON plan from live read-only inventory. All IDs below are synthetic placeholders to replace; the script rejects empty GUIDs and identity mismatch. `script_sha256` is the lowercase SHA-256 of the reviewed preflight script. Preserve a digest of the saved plan bytes as evidence and, for a future registered task, bind those bytes through its administrator-defined typed parameters. A local plan digest never authorizes execution.
+
+```json
+{
+  "schema_version": "1.0",
+  "lab_id": "directory-lab-20261030-fixture01",
+  "domain_dns": "directory-lab.test",

+  "backup_parent": "D:\\ProtectedDirectoryLab",
+  "script_sha256": "REPLACE_WITH_REVIEWED_SCRIPT_SHA256",
+  "timeout_seconds": 300
+}
+```
+
+The plan is a source-only fixture description, not an execution request. Its `.test` suffix is an explicit harness restriction, not evidence of isolation. Existing domains with another suffix need a separately reviewed fixture plan; do not rename a real domain to satisfy this check.
+
+From the source root, validate the plan without connecting to AD:
+
+```powershell
+powershell.exe -NoProfile -File tests/check_identity_directory_lab.ps1 -PlanPath D:\ProtectedDirectoryLab\plan.json
+```
+
+With approved read-only access, an isolated lab operator can add `-ReadOnly` to inspect exactly those two DCs, replica health/recency, SYSVOL/NETLOGON availability, fixture identities, disabled nonprivileged user, Recycle Bin state and matching GPO AD/SYSVOL version counters. The script creates no backups and changes no directory or policy state. `-Execute` always refuses **before** reading plan metadata or importing AD/GPMC. Neither a forged approval field nor an owner-run flag enables it.
+
+Native LDAP/SMB/GPMC calls can exceed the declared planning deadline: use an external process/session watchdog for read-only probes. Even successful preflight returns `partially_verified`; matching counters and shares do not establish SYSVOL content integrity, client application, effective delegation or recovery.
+
+## External owner-controlled recovery drill
+
+This is a concrete **planned** integration drill, not an executable agent mutation path. The separate lab owner uses their own protected change process and tools. Agent-driven execution remains blocked until an administrator installs an immutable typed AD task on a separately protected worker, reviews its exact target/parameter/risk boundaries, and supplies external signed grant plus exact destructive R4 admission. Do not add that task, signing keys, write credentials, registry or bypass to this public source checkout. The task must journal intent/outcome, enforce the actual lock and recheck admission and fresh state by phase; a local operation_gate ALLOWED result is insufficient.
+
+1. Establish a clean baseline: record domain and both NTDS identities; exact user GUID/SID, original parent/name, disabled state, attributes, memberships and delegation; exact unlinked GPO GUID, marker, report, DACL/WMI and versions. Back up the dedicated GPO in protected storage and record the fresh backup-instance ID and artifact digests. Demonstrate usable independent lab recovery before deleting a fixture.
+2. Immediately before deleting the exact fixture user, re-read its SID/GUID/parent, disposable marker, account/protected state and memberships, and compare the write-DC change metadata with the baseline. Any drift aborts. The owner deletes only that fixture and observes the same tombstone GUID on both DCs within a deadline.
+3. Immediately before exact object restoration, recheck deleted/restorable state, lastKnownParent, Recycle Bin eligibility, original parent GUID/DN/marker and absence of name conflicts. A missing parent, unexpected privilege or changed method requires a new owner decision. After restoration, both DCs must show the original GUID/SID/location, disabled nonprivileged state and intended links; an unrelated fixture must be unchanged.
+4. Immediately before changing the benign GPO marker, re-read its complete policy/permission/WMI/description/version and external links against the original baseline. It must still be dedicated and entirely unlinked. Compare report content after removing only generated ReadTime, and check the exact baseline registry value. An unexpected link, edit, permission or version change aborts before any GPO mutation.
+5. After the owner changes the one benign marker, record the exact expected resulting report/version. Immediately before backup-ID restore, repeat the live checks against that expected state, including the unlinked condition and backup digest. Abort on concurrent changes rather than overwriting them. Restore only the reviewed existing GPO from that exact backup instance; then verify the baseline marker/content and both DCs' GPC/GPT convergence. Deleted-GPO recovery is a separate untested method.
+6. Retain redacted timestamps, elapsed recovery, source/task digests, expected/observed results and partial-state flags. On failed/unknown outcome stop, preserve backups and reconcile state before retrying or cleanup. Never force replication or perform an unapproved automatic rollback. Remove only exact owned fixtures through a separately reviewed cleanup.
+
+Until these steps actually run with acceptance evidence, object and GPO recovery stay `not_run`. This repository currently ships no runnable destructive AD integration task.
+
+## Required domain acceptance matrix
+
+Run each row under an exact owner-approved fixture plan and preserve timestamped source commit, target/build IDs, command results, expected/observed difference, elapsed recovery and artifact hashes. Missing rows remain `not_run`; unknown/failed rows prevent a verified domain claim.
+
+| Scenario | Fault and expected evidence | Recovery/negative check |
+|---|---|---|
+| AD versus SYSVOL | On isolated fixture infrastructure, an owner-controlled network fault makes one serving DC stale; inspect partner result/time, exact object metadata and GPC/GPT independently | Restore the exact network before-state through its owner; normal replication converges before deadline. Never force replication to pass |
+| Non-applied policy | Link a separate benign canary policy only to its pilot OU; demonstrate the intended computer value and fresh computer RSoP/GroupPolicy activity/DC | An excluded canary identity lacks the value and shows the correct filtering reason. WMI false, disabled half and stale token are distinct cases |
+| Inheritance | Separate parent/child fixture OUs and benign conflicting settings show order 1, inheritance block and enforced-ancestor behavior | Remove only the test deltas; verify expected winner on client. Keep default domain/controller policies untouched |
+| Delegation | A dedicated limited identity performs its approved action inside one fixture OU | The same identity is denied the comparable action in a separately named sibling OU and cannot edit/link an unrelated GPO. An admin token is invalid evidence |
+| Single object | External exact-fixture delete/restore drill above | Original GUID/SID/location, disabled state, expected links and no unexpected privilege on both DCs; another fixture remains unchanged |
+| Existing GPO | External marker change/backup-ID restore drill above | Restored setting and AD/GPT convergence, independent permission/link/WMI baseline; a separate canary processing cycle proves the selected settings |
+| Refusal | Current preflight rejects wrong plan/domain/DC/GUID/marker, default GPO, unhealthy baseline or modified script; `-Execute` always refuses. A future external task must additionally reject linked/changed fixtures, expired grants, missing exact admission and drift | Current harness performs zero mutations. External task refusal must occur before its affected write; unknown state is not success |
+
+SYSVOL authoritative/non-authoritative recovery, deleted-GPO recovery, forest/DC disaster recovery, protected objects, trusts and unsupported classes remain specialist rehearsals beyond this fixture. A clean lab, matching versions or an offline fixture cannot substitute for those tests.
+
+## CI and reporting boundary
+
+The existing PR validation remains enabled, including Windows-host native fixtures. New regression tests exercise script parsing, plan/digest boundaries and refusal without connecting to a domain; refusal tests trap all native calls before an execution request can reach AD; evaluation fixtures support independent agent forward-testing and do not automatically grade the agent's behavior. No domain integration success is claimed by those jobs. Until the separate lab is actually executed and the acceptance rows have evidence, report domain behavior as `partially_verified` with each missing scenario listed.

+# Recover one AD object or GPO
+
+Read before restoration. Object/GPO recovery is R4: bind the exact immutable target, artifact and method to the contract-v2 request, independent approvers where required, change lock, current window, backup/restore evidence and recovery owner. A request to diagnose does not approve recovery. Export the current state first, preserve concurrent evidence and confirm healthy replication; restoration of an object is not a domain-wide rollback.
+
+For agent execution, these commands describe the planned method only. Platform 0.15 requires a protected administrator-registered immutable typed task, external signed grant and exact destructive R4 admission. Local gate output or unsigned approval metadata cannot authorize a native command. No such AD task is shipped here: absent that external capability, provide the exact recovery plan and keep execution blocked.
+
+## Deleted directory object
+
+Confirm the forest/domain GUID, writable DC, original objectGUID/SID, class, deletion time, `lastKnownParent`, `msDS-lastKnownRDN`, `isDeleted` and `isRecycled`. Query the exact GUID with `Get-ADObject -Identity <guid> -IncludeDeletedObjects -Server <dc> -Properties ...`; never pipe a wildcard result into restore. Verify the parent still exists and the original name is free. An alternate parent or name changes the plan and requires new approval.
+
+Establish whether Recycle Bin was enabled **before** deletion and whether the object remains within the restorable deleted-object lifetime. Enabling Recycle Bin now does not restore previously stripped attributes and is itself a separate forest-wide, irreversible feature decision. A recycled/expired object, unsupported object class or missing retention evidence requires a topology/version-specific backup recovery handoff; do not guess a tombstone reanimation or authoritative restore procedure.
+
+For a confirmed eligible object use only the approved exact `Restore-ADObject -Identity <guid> -Server <dc> -TargetPath <approved-parent-dn>` slice. Restore a deleted parent before its explicitly listed child, with separate bounded dependencies; never recursively recover an unknown subtree. Verify the original GUID/SID, intended parent/name, required attributes and group links on the relevant replicas. Inspect disabled/account state, protected flags, delegated ACLs and privileged membership before allowing use. Refresh tokens and perform the intended allowed and denied user/service checks. Membership links, trust relationships and applications need their own acceptance; object existence alone is partial evidence. If a restored account would gain unexpected privilege, stop and coordinate containment with the access owner rather than blindly deleting it again.
+
+## GPO setting rollback
+
+Distinguish the GPO GUID from the backup-instance ID. Select one trusted `Backup-GPO` instance by exact backup ID, original domain/GPO GUID, timestamp, protected path and digest; never restore "latest" by display name. Save the current GPO and independently export its links, order/enforcement, security filter/delegation, WMI association and canary baseline. GPO backup is not a backup of the entire directory, linked OUs or WMI-filter definitions.
+
+`Restore-GPO -BackupId <backup-id> -Path <protected-directory> -Domain <original-domain> -Server <dc>` restores a backup to its original domain. The planned isolated fixture scenario is rollback of an **existing**, dedicated GPO; no live recovery result is claimed. The cmdlet documentation states it fails when the original GPO no longer exists: stop and use a separately rehearsed GPMC/specialist recovery plan for a deleted GPO. Do not promise that AD Recycle Bin alone restores a complete GPO: both GPC and GPT are required. Never copy a policy directory or edit GPT.INI to manufacture one.
+
+`Import-GPO` is a different operation: it transfers backed-up settings into a destination GPO, retaining destination links/security filtering, and can need an explicitly reviewed migration table for domain-specific principals/paths. A cross-domain import or recreation changes identity and scope and is not an equivalent fallback for failed restore. Reapprove the exact destination, mapping and canary.
+
+After restore reconcile AD and SYSVOL on both the write DC and relevant serving DCs; version numbers can advance during recovery, so compare intended policy contents as well as convergence. Re-read links, filters, WMI and permissions independently against the approved before-state; recreate a missing external link only as a separate scoped change. Process policy on the approved canary under the host owner's plan and prove both the setting and exclusion/denial. Preserve recovery timing, unresolved state and a compatibility-aware rollback choice. No live domain evidence means `partially_verified`, even when offline or Windows-host tests pass.

+# Policy applicability, inheritance and delegation
+
+Read for a linked policy that does not apply, an unexpected winning setting, or an administration permission failure. Keep the problem distinct: permission to edit a GPO, permission to link it to an OU, and permission for a principal to read/apply it are different rights.
+
+## Trace one policy to one affected identity
+
+1. Confirm the exact user SID, computer SID, their current OUs, GPO GUID, setting and user/computer half, client build, logon/session and processing time. Capture client-selected DC and the user's actual token/group state. A group change may require a new logon or computer authentication context; membership shown in AD does not update an existing token.
+2. Collect a fresh `gpresult /scope computer /r` in the appropriate elevated context and `gpresult /scope user /r` in the affected user's context, or protected HTML/XML reports for that target. Correlate GroupPolicy Operational and System events by the processing activity ID/time. An administrator's user report does not describe another user's session. Reports can contain private paths, names, scripts and settings: redact before sharing, and never execute report content.
+3. With an explicit domain/DC, use `Get-GPInheritance -Target <exact-ou-dn>` to inspect direct and inherited links, enabled state, order, enforced links and block inheritance. Trace local/site/domain/OU processing, including the actual AD site. Within one container, link order 1 has higher precedence. Block inheritance does not defeat an enforced ancestor link. A linked/apparently inherited GPO is still subject to its applicability checks.
+4. Check the GPO's enabled halves, security filtering and effective Read plus Apply Group Policy for the intended target, including explicit deny and nested groups. User policy retrieval also needs the computer's read access under current Windows behavior; distinguish read-only access from Apply. Examine WMI filter result on the actual client, loopback Merge/Replace and Group Policy Preferences item-level targeting. Preferences, tattooed settings and CSE-specific refresh/restart/logon requirements can explain a persistent value even after a GPO disappears.
+5. Check both GPC and GPT replication on the DC actually used by the client using [replication-and-sysvol.md](replication-and-sysvol.md). Then inspect extension failures, network/startup timing, synchronous processing and conflicting management mechanisms. Do not use `gpupdate /force`, reboot, unlink/relink, broad filtering or disabled security as a diagnosis. A refresh can execute settings/scripts and needs approved target scope.
+
+Verification must name the winning setting/value on the intended canary and show a denied or excluded principal does not receive it, after the necessary approved processing cycle. Capture the client DC, policy GUID/version and observation interval. Neither GPMC modeling nor a successful link/edit command proves live application.
+
+## Delegation branch
+
+Read the exact OU/object security descriptor and each affected GPO's `Get-GPPermission -Guid <guid> -All -Domain <domain> -Server <dc>` result. Resolve trustee SIDs, access masks/extended-right GUIDs, object-class/property scope, inheritance flags, explicit/inherited ACEs and deny entries. Check OU Create/Delete Child versus object Write Property rights, GPO edit versus link rights (`gPLink`/`gPOptions`), ownership and group nesting separately. Include protected-object/AdminSDHolder behavior and `adminCount` when inheritance unexpectedly differs; never reset protection or inheritance globally to make delegation work.
+
+Prepare only the exact ACE delta, with its before-state, destination object/class and descendant scope. A generic OU permission template can grant escalation through password resets, group membership or GPO control. Verify using the delegated identity: one allowed action on an approved disposable canary and one meaningful denied action outside the scope. Admin success, an ACL listing or `-WhatIf` is insufficient. Restore only the changed ACEs under the same bounded recovery plan; do not replace a whole OU descriptor over unrelated concurrent changes.

+# AD replication and SYSVOL diagnosis
+
+Read for a replication alert, a DC serving different policy, or missing SYSVOL/NETLOGON. Identify the exact writable DCs, naming contexts, sites, topology, relevant interval, and last known good state. Keep the first pass read-only and bounded to approved servers; raw reports expose topology and principals.
+
+## Separate the two replication paths
+
+AD replication carries the Group Policy Container (GPC), directory objects and links. DFS Replication carries the Group Policy Template (GPT) in SYSVOL. Success in one path does not establish success in the other. An accessible SYSVOL share does not prove up-to-date policy contents.
+
+For each named DC, collect `Get-ADReplicationPartnerMetadata -Target <exact-dc> -Partition <exact-naming-context> -PartnerType Inbound`, `Get-ADReplicationFailure -Target <exact-dc> -Scope Server`, and, for one affected object, `Get-ADReplicationAttributeMetadata -Object <exact-dn> -Server <exact-dc>`. Capture attempted/successful replication times, result codes, failure counts, originating version/time/invocation identity and the naming context. A success before the incident or no returned partners is insufficient. USNs are local to a DC: do not compare their raw values across servers as convergence evidence. Reconcile the chosen object's actual attributes and originating metadata across the relevant replicas, after the normal schedule and within an explicit deadline.
+
+Use `repadmin /showrepl <exact-dc>` and `dcdiag /s:<exact-dc> /test:Replications /test:SysVolCheck /test:NetLogons` when applicable to the installed build. Preserve native exit codes and per-test results. Attribute DNS locator, time/Kerberos, RPC/firewall, unavailable partners and naming-context failures to their owner; do not erase the symptom by forcing synchronization. A forest-wide summary is context, not evidence that this object or GPO converged.
+
+## SYSVOL branch
+
+On each relevant DC inspect SYSVOL and NETLOGON share availability, DFSR service state and bounded DFS Replication events. Investigate 2213 (paused recovery), 4012 (content freshness), and 4614 without subsequent 4604 (initial synchronization not completed); correlate times and current folder state rather than treating an old event ID as a current diagnosis. Confirm whether the domain uses DFSR; do not apply legacy FRS BurFlags recipes to DFSR.
+
+For the exact GPO GUID, compare `Get-GPO -Guid <guid> -Domain <dns-domain> -Server <dc>` user and computer AD/SYSVOL versions on every relevant DC, and inspect that DC's explicit `\\<dc>\SYSVOL\<domain>\Policies\{<guid>}\GPT.INI` and required policy files. A domain DFS path can select a different DC. Matching version counters alone do not prove matching contents or client application; compare protected hashes of the affected files when diagnosing suspected divergence.
+
+Stop policy changes when AD/GPT disagree, a partner is unknown, initial sync is incomplete, or no authoritative healthy copy is established. Preserve copies and metadata before a separately approved recovery. Never delete the DFSR database, set an authoritative flag, edit GPT.INI, change freshness thresholds or use `/syncall` as routine repair. Authoritative/non-authoritative SYSVOL recovery and forest/DC disaster recovery require an exact R4 topology-specific plan, a proven backup, directory owner and independent recovery access.
