+# Native provider configuration acceptance
+
+The dedicated `Native provider configuration acceptance` workflow tests the public `provider-packs` command on disposable GitHub-hosted Windows Server 2022 and 2025, separately under Windows PowerShell 5.1 and PowerShell 7. It complements the read-only manifest inventory and mocked failure tests described in [the provider-pack guide](native-provider-packs.md).
+
+This fixture is destructive to the selected channels' temporary configuration and can discard records when restoring smaller buffers. It requires `-AllowDisposableProviderWrite`, `GITHUB_ACTIONS=true` and `RUNNER_ENVIRONMENT=github-hosted`; do not run it on ordinary machines. Production behavior is unchanged; only this opted-in disposable fixture prepares and restores the temporary test settings.
+
+## Actual public behavior checked
+
+- The real provider/channel registrations and expected event schemas must permit all four explicitly selected client-side packs: `dns-client`, `capi2`, `winrm` and `rdp-client`. Missing or incompatible metadata fails the fixture; it is never replaced with a mock or skipped success.
+- Plan and Configure with `-DryRun` preserve prepared native settings. Unsupported preview and reader-grant options are refused before a recovery directory is created.
+- Configure actually enables the four channels and applies their exact minimum buffers. A prepared 2 GiB WinRM buffer stays larger, and a prepared CAPI2 `Retain` mode stays intact. The complete descriptor is preserved; provider packs never request an Event Log Readers grant.
+- Every Applied result and its original journal entry are compared with independent native before/after observations. Repeated Configure is idempotent and creates no write journal.
+- Both manual DNS packs refuse configuration. The hosted image must genuinely lack the DNS Server service, and `dns-server-audit` must refuse that missing prerequisite. No DNS role is installed or removed to manufacture the result.
+- A mixed CAPI2/manual-DNS invocation performs one real selected change and reports the other failure with a nonzero overall exit and exactly one journal entry. Partial application is explicit.
+
+The fixture does not issue DNS queries, RDP connections or WinRM sessions, change service configuration, or intentionally generate test events. Ordinary background Windows events may occur while the channels are enabled. All rules retain zero Ready credit; enabling a source does not establish event fields, effective reader access, ingestion or matching backend queries.
+
+## Preservation, cleanup and evidence
+
+Before preparation, the fixture captures native settings and complete `wevtutil gl /f:xml` configuration for registered catalog channels and additional unselected Security, System, Application, AppLocker and DriverFrameworks controls. During public configuration it compares every selected XML field except the permitted enabled flag and maximum size; unselected registered channels must remain byte-for-byte equivalent at the XML level. It also compares the state/start type of EventLog, Winmgmt, WinRM, TermService and DNS, and all 59 effective audit masks.
+
+Each selected channel has independent cleanup that restores original enablement, exact byte limit, descriptor and retention/backup mode. A failure restoring one channel does not skip the remaining channels. Final observations compare original full XML, service state and audit masks. Cleanup failure prevents a passing result. Owned child commands have bounded execution and output, and termination failures remain in the cleanup receipt.
+
+`original.json`, public JSON reports, command output, actual journals, `completed.json`, `cleanup.json` and a SHA256 manifest are retained for seven days by the workflow. The manifest binds the fixture, product helpers, catalog, corpus and full reviewed rule-source bytes. Event records are not restored, and no retention-duration, Windows 11, domain/DC/ADCS, positive installed-DNS, forwarding or Sigma acceptance is implied. This advances issues #386 and #366 without closing their broader acceptance work.
+
+The underlying enablement, size, retention and backup options follow Microsoft's [wevtutil command reference](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/wevtutil). The product's existing channel floors and schema gates remain unchanged.
+
+The first native run exposed a WinRM manifest bug: an unrelated event ID `3221734403` overflowed the reader's signed 32-bit cast and made the whole provider schema unknown. The reader now compares [EventMetadata.Id in its native Int64 domain](https://learn.microsoft.com/en-us/dotnet/api/system.diagnostics.eventing.reader.eventmetadata.id), then parses only the exact reviewed event/channel templates. Focused tests also require refusal when only unrelated large IDs exist; schema gates are unchanged.

+# Native collector subscription observations
+
+The existing `wec-collector` Audit and Plan commands now enumerate subscription names through the local Windows Event Collector API and read selected XML through the shared bounded Unicode reader. This avoids treating PowerShell console output, including a BOM-only empty result, as subscription identity. Non-ASCII descriptions and XPath literals remain intact in the report.
+
+```powershell
+.\WELA.ps1 wec-collector -WefAction Audit `
+  -WefConfigPath C:\Reviewed\collector.json -ResultsPath C:\Evidence\collector-audit.json
+.\WELA.ps1 wec-collector -WefAction Plan `
+  -WefConfigPath C:\Reviewed\collector.json -ResultsPath C:\Evidence\collector-plan.json
+```
+
+Use the explicit collector configuration described in [WEF deployment](wef-deployment.md). These commands observe the selected local subscriptions and prerequisites. They do not create, save, enable or delete subscriptions. Existing Configure remains create-only and retains its domain, listener, ingress and hardening prerequisites.
+
+A successful complete enumeration can establish `ObservedSubscription.Exists: false`; its `ObservedEnabled` remains null. An enumeration error, cap, duplicate/invalid native name, vanished or unreadable selected definition, mismatched XML identity or unsupported authorization remains unknown, with `ObservationError` and an `Unknown` control. Failed observations never authorize creation. A valid disabled definition is reported as disabled even when the requested XML says enabled. A readable difference requires manual review rather than a replacement.
+
+Enumeration preserves exact native UTF-16 names, including Unicode and whitespace; it does not trim names or parse localized command output. It is limited to 4,096 names, 1,023 UTF-16 characters per name and 1,048,576 total characters including terminators. Exceeding a bound fails the observation instead of returning a partial list. Selected subscription IDs continue to use the existing supported ASCII ID syntax, and native XML reads retain their ten-MiB and thirty-second bounds. Native API errors are preserved as failures. The loaded enumeration helper is bound to its implementation bytes.
+
+Enumeration and XML readback are sequential observations, not a transaction or protection against another administrator. A disappearing subscription is unknown for that observation; retry with a fresh audit. A complete configuration match still does not establish source identity, effective source access, runtime health, event arrival, bookmark continuity or Sigma coverage. Collector-local channel observations describe only the collector.
+
+The disposable native suite exercises the actual public commands on Server 2022/2025 with Windows PowerShell 5.1 and PowerShell 7. It uses one uniquely owned disabled subscription with Unicode description and XPath, verifies absence, exact observation, requested/observed state separation, changed-description review and authorization-mismatch uncertainty, then removes only the owned subscription and restores original service startup/state. It preserves the destination channel and original subscription inventory. The real standalone fixture remains `Incomplete` with exit 1 for domain deployment prerequisites; those checks are neither mocked nor counted as domain or forwarding proof. Native name-buffer, cap, duplicate and read-failure regressions supplement that Windows acceptance.

 ## Subscription XML and evidence
 
+[Native collector observations](wec-collector-observation.md) use complete bounded WEC name enumeration and strict Unicode XML reads. Failed or partial observations remain unknown; they never become permission to create a subscription. Raw Unicode descriptions/filters and actual disabled state are retained independently of the requested settings.

 The supported input is the native Subscription namespace, SourceInitiated type, native EventLog URI, HTTP transport, ForwardedEvents destination and Normal/MinLatency/MinBandwidth delivery preset. Enabled, ReadExistingEvents, content format and locale must be explicit. QueryList uses unique numeric Query IDs, exact native channel paths and nonempty Select/Suppress XPath expressions. Wildcard/provider channel names, external-provider channels, Sysmon/EMET, DTDs, unknown settings and custom delivery are rejected. This checks supported structure, not Windows XPath execution; native `cs` remains the final syntax validator.
 
 An empty `AllowedSourceDomainComputers` input is filled from the explicit `SourceSids`; a nonempty value must match that authorization exactly. No empty authorization reaches `wecutil`, avoiding Windows' broader default authorization. Non-domain/certificate authorization is not supported. The example Security 4740 filter is illustrative and is not a complete baseline or a recommendation to lock an account for testing.

 `before.jsonl` is written before each mutation. Review its exact Target/Before/Desired and the results before recovery. For a newly created subscription, it records absence and stores the prepared XML; remove that exact ID only after verifying its current definition still belongs to this run. Existing subscriptions are never edited. For the new SubscriptionManager value, compare the current value with Desired before removing only that value; keep other list entries and parent keys. Restore WSMan values and service start/running states only after verifying their present state and current policy authority. Remove only the newly added group SID after comparing the full membership snapshot; DC membership is never changed by this workflow. For channel restoration, use the channel journal and descriptor-preservation guidance. Recovery is deliberately manual so a newer operator/GPO change is not overwritten.

+Safe fixture tests exercise the public command/report, journals, readback failures, occupied slots, explicit authorization, native create failures, configuration drift, DC group protection and blocked prerequisites. Windows PowerShell 5.1/PowerShell 7 CI adds real **read-only** channel, service, WSMan, firewall and ADMX assessment. Those read-only smoke tests do not deploy subscriptions or prove forwarding. The separate [native observation fixture](wec-collector-observation.md) now exercises public Audit/Plan against one owned disabled subscription on standalone Server 2022/2025 runners, preserving real unmet domain prerequisites and exact fixture cleanup; it does not test domain deployment or delivery.
 
 Before closing issue #368, an isolated domain lab must configure a dedicated collector and Windows 11/member-server/DC/AD CS sources, verify source identity/token read access (including any required token/service refresh), preserve runtime status, and demonstrate native events matching each selected query arriving with the expected source identity/timestamps. Include disabled-query, denied-source, absent-channel, GPO refresh, idempotence, drift and recovery cases. Use a deliberately chosen benign native Application/System event or a controlled test account/object relevant to the query; record actual events, not merely a successful command or ACE. Forwarded Sigma coverage remains unassessed until those events and the processing pipeline are validated.

 - Add `outgoing-ntlm` Audit/Plan/Configure to manage the outgoing audit DWORD independently of broad configuration. Preserve existing deny by default, require explicit Audit to replace it, refuse unknown types/values and pre-write drift, and retain typed original journals plus native readback. Native Server 2022/2025 tests verify narrow scope and exact cleanup; authentication/event generation remain unverified. (Related #362) (@Shirofune-Security)
 
+- Fixed collector subscription observations to use complete bounded native name enumeration and strict Unicode XML reads instead of console decoding. Empty inventories, failed reads and actual disabled state remain distinct; Unicode descriptions and XPath are preserved. Disposable public Audit/Plan tests cover both Server 2022/2025 and PowerShell engines with exact cleanup, without domain deployment, forwarding or Sigma claims. (Related #368) (@Shirofune-Security)
+
+- Added disposable native acceptance for public provider-pack Plan, DryRun, Configure, idempotence, missing/manual refusal and partial outcomes on Server 2022/2025 under Windows PowerShell 5.1/PowerShell 7. Actual DNS Client, CAPI2, WinRM and RDP Client configuration preserves descriptors, retention, larger buffers, unrelated channels, services and all audit masks, with journal/hash evidence and exact fixture cleanup; no event or Sigma credit. Fixed WinRM manifest inspection to preserve native Int64 event IDs, so unrelated large IDs no longer block the selected event schema. (@Shirofune-Security)

 - Verify public Security-log warning configuration on disposable Server 2022/2025 hosts under Windows PowerShell 5.1/PowerShell 7: absent/zero/higher thresholds, earlier-threshold preservation, dry run, idempotence, wrong-type refusal and exact cleanup. Preserve unrelated registry values, channel configuration, audit masks and CrashOnAuditFail; no log-exhaustion or warning-event claim. (@Shirofune-Security)
 
 - Added disposable public `targeted-sacl` registry lifecycle validation on Server 2022/2025 and both PowerShell engines. A fixture-owned mounted hive exercises reviewed selection, DryRun, additive configuration, stale/prerequisite refusal and idempotence, followed by one precisely attributed Security4657. Retained native receipts verify unrelated ACE/value preservation and exact audit-policy, token and owned-hive cleanup; production does not load hives or gain Sigma credit.
