Control 2.5 — PowerShell Setup: Testing, Validation, and Quality Assurance Automation

Scope. This playbook automates the evidence-bearing planes of Control 2.5 for Microsoft 365 Copilot agents, Copilot Studio agents, and Azure AI Foundry-hosted agents in US financial services tenants. It assumes you have already read ../../_shared/powershell-baseline.md (referenced below as BL-§N) and the parent control specification ../../../controls/pillar-2-management/2.5-testing-validation-and-quality-assurance.md.

What this playbook is. A reproducible, fail-closed harness that (a) pins versions, (b) bootstraps a sovereign-aware session, (c) executes the five Control 2.5 evidence planes (Copilot Studio test sets, Azure AI Evaluation SDK metrics, PyRIT adversarial campaigns, Power Platform Solution Checker, Pipelines deployment gates), (d) emits SHA-256-hashed evidence with a signed manifest, and (e) supports the three-signature attestation chain (developer / validator / supervisor).

What this playbook is not. It does not replace human red-team review, model-risk-management sign-off, or Designated Supervisor attestation. The harness raises evidence; people accept risk.

Hedged language reminder. Output of this harness supports compliance with FINRA 3110/2210, SEC 17a-4, SR 11-7, and OCC 2011-12 evaluation expectations. It does not, by itself, guarantee compliance, ensure a passing exam, or eliminate model risk. Organizations must verify thresholds, evaluator versions, and dataset provenance against their own model-risk policy.

§0 — Wrong-shell trap and tooling matrix

Why this section exists. Control 2.5 evidence is silently invalidated when the wrong PowerShell edition autoloads a stale module, when the Power Platform CLI (pac) is on a cached profile from another tenant, or when Python imports a deprecated azure-ai-evaluation evaluator name that returns null scores instead of erroring. This section establishes the canonical shell, traps the common edition/profile mismatches, and prints the tooling matrix every operator must satisfy before proceeding.

Required shell.

# Run at the top of every Control 2.5 session
if ($PSVersionTable.PSEdition -ne 'Core' -or $PSVersionTable.PSVersion.Major -lt 7) {
    Write-Error "Control 2.5 requires PowerShell 7.4 LTS Core. Detected: $($PSVersionTable.PSEdition) $($PSVersionTable.PSVersion). Launch 'pwsh' (not 'powershell.exe') and retry."
    exit 2
}
if ($PSVersionTable.PSVersion -lt [version]'7.4.0') {
    Write-Error "PowerShell 7.4.0 or later is required (LTS). Detected: $($PSVersionTable.PSVersion)."
    exit 2
}
# Trap accidental Windows PowerShell module shadowing
$desktopPaths = $env:PSModulePath -split ';' | Where-Object { $_ -match 'WindowsPowerShell\\Modules' }
if ($desktopPaths) {
    Write-Warning "Windows PowerShell module paths are visible to pwsh: $($desktopPaths -join '; '). Stale PnP.PowerShell v1 or Microsoft.Graph v1 modules can autoload. See BL-§2."
}

Tooling matrix (April 2026 baseline).

Tool	Minimum version	Purpose	Sovereign notes
PowerShell Core	7.4.0 LTS	Primary shell	All clouds
Windows PowerShell Desktop	5.1	`Microsoft.PowerApps.Administration.PowerShell` sub-shell only (BL-§2)	Windows hosts only
Power Platform CLI (`pac`)	1.36.0	Solution Checker, Pipelines, agent export	`--cloud {Public\\|UsGov\\|UsGovHigh\\|DoD}`
Azure CLI (`az`)	2.60.0	AI Foundry project lookup, Log Analytics ingest token	`az cloud set --name {AzureCloud\\|AzureUSGovernment\\|AzureChinaCloud}`
Microsoft 365 Agents Toolkit CLI (`m365`)	6.0.0	Declarative-agent provisioning + manifest hashing	Public + GCC verified; GCC-High limited
Python	3.11.0	`azure-ai-evaluation`, `pyrit`	OSS, portable across all clouds
Git	2.40.0	Manifest provenance	n/a
OpenSSL or `Get-FileHash`	n/a	SHA-256 evidence hashes (BL-§5)	n/a

Fail-closed conditions:

Detected PowerShell edition is Desktop, or version < 7.4.0 → exit 2.
pac CLI missing or < 1.36.0 → exit 2 in §7 and §8.
Python interpreter resolved is not the project venv → exit 2 in §5 and §6 (see §1 venv guard).
Windows PowerShell Modules directory is on $env:PSModulePath AND a probe in §1 detects PnP v1 or Microsoft.Graph v1 — exit 2.

§1 — Module, CLI, and Python package pinning

Why this section exists. Evaluator scores, content-safety verdicts, and red-team converters change semantics across versions. An unpinned azure-ai-evaluation may rename GroundednessEvaluator arguments between minor releases; an unpinned Microsoft.Graph may switch a beta endpoint to GA with different selection syntax. Control 2.5 evidence is reproducible only when versions are declared, hashed, and emitted into the manifest.

pac, az, m365, or python not on PATH, or below minimum versions → exit 2.

§2 — `Initialize-Agt25Session`: sovereign-aware bootstrap

Why this section exists. Every Control 2.5 run must declare its sovereign cloud once, derive every endpoint from that declaration, and refuse to mix endpoints across clouds. A silent cross-cloud call (e.g., issuing a Public-cloud OpenAI evaluator request against a GCC High agent) produces evidence that cannot be admitted by an examiner because the data crossed an authorization boundary.

Fail-closed conditions:

Cloud parameter not in the validated set → parameter binding error (exit 2 upstream).
pac auth create --cloud fails or is skipped → §7/§8 must exit 2.
Connect-MgGraph -Environment resolves to a different environment than requested → exit 2.
Sovereign hard-stops (DoD/China for Copilot Studio; DoD/China and partial GCC/GCCHigh for AI Foundry Evaluation) without a documented exception in session.json → §9 manifest validation exit 2.
evidence/agt25/<RunId>/ directory cannot be created (filesystem read-only) → exit 2.

§3 — `Test-Agt25Prerequisites`: read-only environment probes

Why this section exists. Before any test executes, the harness must confirm read-only access to: the agent under test, the Copilot Studio environment, the AI Foundry project, the Log Analytics workspace, and the evidence Storage Account / SharePoint library. A test run that "passes" because the agent was unreachable produces a false-clean — the worst possible Control 2.5 outcome.

Fail-closed conditions:

Any check with Severity='Critical' returns Pass=$false → exit 2.
Probe completes but no probes ran (zero results) → exit 2 (defensive: indicates a logic bug).
Token acquisition for AI Foundry endpoint succeeds in cloud Public while session declares GCCHigh/DoD → exit 2 (cross-cloud call detected).

§4 — Copilot Studio test sets: export the regression baseline

Why this section exists. The Copilot Studio Test Pane is interactive and ephemeral; its results cannot be admitted as evidence under SEC 17a-4 because they are not WORM-retained, not signed, and not reproducible. The supported evidence-bearing path is to (a) export the published agent's regression test set as JSON, (b) execute the test set headlessly via pac copilot test run (or the equivalent Power Platform Test Engine batch), (c) hash the input dataset and the output transcript, and (d) write both into the §9 manifest.

Skip condition. If $Session.Profile.CopilotStudioGA -ne $true, write a documented exception and skip this section. DoD and China (April 2026) hard-stop here.

Zone 1 (Personal)	0.80	unbounded for transparency-only agents
Zone 2 (Team)	0.90	<= 5% of suite
Zone 3 (Enterprise)	0.95	zero failed in regulated-data scenarios

Fail-closed conditions:

pac copilot testset export or run exits non-zero → exit 2.
Exported test set is empty ($report.testCases.Count -eq 0) → exit 2 (false-clean trap).
passRate < zoneThreshold for Zone 2 / Zone 3 → soft fail (exit 1 at §9 rollup).
Any failed test case in Zone 3 with regulated-data tag → hard fail (exit 2 at §9).
Dataset SHA-256 cannot be computed (file unreadable) → exit 2.

§5 — Azure AI Foundry Evaluation SDK: scored metrics with hashed datasets

Why this section exists. Copilot Studio's built-in test set verifies behavioral pass/fail; SR 11-7 and OCC 2011-12 require quantitative quality metrics (groundedness, relevance, coherence, fluency, similarity), content-safety verdicts, and protected-material checks. The Azure AI Evaluation SDK (azure-ai-evaluation) emits these as numeric scores against a hashed evaluation dataset, with a separately versioned judge model (which MUST NOT equal the subject model — segregation of duties on inference).

Required evaluators (April 2026 baseline).

Evaluator	Module path	Notes
`GroundednessEvaluator`	`azure.ai.evaluation`	Requires `query`, `response`, `context`
`RelevanceEvaluator`	`azure.ai.evaluation`	LLM-judge metric
`CoherenceEvaluator`	`azure.ai.evaluation`	LLM-judge metric
`FluencyEvaluator`	`azure.ai.evaluation`	LLM-judge metric
`SimilarityEvaluator`	`azure.ai.evaluation`	Reference required
`F1ScoreEvaluator`	`azure.ai.evaluation`	Lexical, no judge
`ContentSafetyEvaluator`	`azure.ai.evaluation`	Hate, Violence, Sexual, SelfHarm

Any content-safety severity exceeds the zone ceiling → exit 2.
LLM-judge metric below threshold → exit 1 (soft fail; supervisor may override with documented justification).
Scorecard JSON cannot be written (disk full / permission) → exit 2.

§6 — PyRIT: adversarial / red-team campaigns

Why this section exists. Quality metrics from §5 measure normal-traffic behavior; they do not measure resilience to adversarial inputs (jailbreaks, prompt injection, encoding bypasses, role-play coercion). PyRIT (Python Risk Identification Toolkit) is Microsoft's OSS framework for systematic adversarial campaigns. Because PyRIT is OSS and runs locally, it is portable across all sovereign clouds — but its memory database (DuckDB) contains adversarial prompts and MUST NOT be committed to source control or stored on user OneDrive.

Components.

Memory. initialize_pyrit(memory_db_type=DUCK_DB) writes to evidence/pyrit/<runId>.db. Add evidence/pyrit/*.db to .gitignore.
Targets. OpenAIChatTarget (the scorer judge); HTTPTarget (the agent under test, called via DirectLine v3 with a validator service-principal token).
Orchestrators. PromptSendingOrchestrator (single-shot baseline); RedTeamingOrchestrator (multi-turn adaptive).
Converters. Base64Converter, ROT13Converter, UnicodeConfusableConverter, TranslationConverter — encode-bypass attacks.
Scorers. SelfAskTrueFalseScorer for refusal verification; SelfAskLikertScorer with HARM_SCALE_PATH for harm gradation; AzureContentFilterScorer for content-safety cross-check.

Runner (scripts/run_agt25_pyrit.py).

Mandatory -WhatIf example (run this first; capture the output as evidence).

Invoke-Agt25PipelineDeployment -Session $s `
    -PipelineId '5e3...c1' `
    -SourceEnvironmentId 'contoso-fsi-test-eus' `
    -TargetEnvironmentId 'contoso-fsi-prod-eus' `
    -SolutionUniqueName 'CoiAdvisor' `
    -EvidenceManifestPath "$($s.EvidenceDir)/manifest.json" `
    -WhatIf

Fail-closed conditions:

Evidence manifest missing or overall_exit != 0 → exit 2.
Validator UPN equals developer UPN in manifest → exit 2 (segregation).
pac pipeline deploy returns non-zero → exit 2 (do NOT retry without manual triage).
Operator skips the -WhatIf rehearsal → policy violation; pipeline approval workflow must reject.
Sovereign cloud mismatch between source and target environment → exit 2.

§9 — `Test-Agt25Implementation`: roll-up validator + signed evidence manifest

Why this section exists. Each preceding section emits an isolated probe object. Section 9 rolls them up into a single signed manifest (manifest.json schema agt25.manifest.v1) that (a) hashes every evidence artifact, (b) records validator/developer/supervisor UPNs for the three-signature attestation, (c) re-checks segregation of duties and sovereign consistency, and (d) emits a single overall exit code that downstream Pipelines (§8), retention (Control 3.5), and Sentinel ingestion (§10) consume as the source of truth.

Fail-closed conditions:

Developer UPN equals validator UPN → exit 2 (cannot self-validate).
Validator UPN equals supervisor UPN where Zone 3 — exit 2 (cannot self-supervise on enterprise agents).
Any artifact referenced by a probe is missing on disk at hash time → exit 2.
Manifest re-hash after attestation differs from pre-signature hash beyond the attestation block → tamper detected; exit 2.
Set-AuthenticodeSignature returns HashMismatch or NotSigned → exit 2.

§10 — Analytics export: long-horizon evidence to Log Analytics / Sentinel

Why this section exists. SEC 17a-4 retention and FINRA 4511 supervisory review require evidence to remain readable and queryable for at least six years. Local SHA-256-hashed JSON satisfies WORM if stored in immutable storage (Control 3.5), but does not support cross-run trend analysis. This section ingests the §9 manifest into a custom Log Analytics table (Agt25_RedTeam_CL, Agt25_Eval_CL, Agt25_Manifest_CL) for Sentinel correlation and supervisory dashboards.

Scheduled re-validation. Zone 3 agents must re-run §3-§9 at least every 90 days, or whenever §1 module versions change, or whenever the subject model deployment SKU rolls. Use Azure Automation or GitHub Actions on the validator's service principal — never on a user identity.

Fail-closed conditions:

DCE/DCR/Stream parameters point to a workspace in a different sovereign cloud than $Session.Cloud → exit 2.
HTTP response is not 204 No Content → exit 2 and queue for replay (do not silently drop).
Scheduled job runs under a user identity (not a service principal with workload-identity federation) → governance violation; CI must reject.
Manifest SHA in ingested record does not equal on-disk SHA at evidence-archive time → tamper; exit 2.

§12 — Anti-patterns (false-clean traps)

A false-clean outcome (the harness reports green when the underlying control is broken) is the highest-impact defect class for Control 2.5. The table below catalogs the 22 most common false-clean traps observed in FSI deployments through April 2026.

#	Anti-pattern	False-clean symptom	Detection / mitigation
1	Run from Windows PowerShell 5.1 instead of pwsh 7.4	Old modules autoload; new cmdlets missing → tests skip silently	§0 edition trap → `exit 2`
2	`PnP.PowerShell` v1 still on `$env:PSModulePath`	`Connect-PnPOnline` resolves to v1 with deprecated parameters	§1 stale-module probe
3	`Microsoft.Graph` v1 autoloaded before v2 import	`-Property` selection silently dropped on some endpoints	§1 stale-module probe
4	Cached `pac auth` profile from a prior tenant	Solution Checker runs against the wrong environment, "passes"	§2 `pac auth clear` before `create`
5	Region-mismatched SPO admin URL	PnP cmdlets succeed against the wrong tenant region	Resolve via Graph `organization` endpoint, not a constant
6	`Set-LabelPolicy` succeeds without changing the rule body	Sensitivity-label probe reports green despite missing rule	Verify with `Get-LabelPolicyRule` after set
7	Stale Python venv with deprecated evaluator names	`evaluate()` returns `null` for renamed metrics → averages skewed	§1 venv bootstrap + pinned `azure-ai-evaluation`
8	Mistaking the Copilot Studio Test Pane for evidence	Interactive results not WORM-retained → not admissible	§4 mandates `pac copilot testset run` headless
9	AI Foundry cross-cloud silent downgrade	GCC High agent evaluated by Public-cloud judge model → data crosses boundary	§2 sovereign hard-stop + §11 endpoint match
10	PyRIT memory DB committed to git	Adversarial prompts leak to source control	§6 `.gitignore` precondition + §9 manifest probe
11	Judge model equals subject model	Self-evaluation always scores high → segregation violated	§5 and §6 hard-stop
12	Validator UPN equals developer UPN	Self-attestation accepted; SoD broken	§9 segregation gate
13	Solution Checker run with a permissive ruleset	High-severity findings re-classified as warnings	§7 `RuleSet='Solution Checker'` enforced
14	Scheduled job runs under a user account	Token expires; quarterly run silently fails for weeks	§10 SP + workload-identity federation only
15	DirectLine token from user identity (not validator SP)	PyRIT `HTTPTarget` 401s; harm count "0" misread as pass	§6 fail-closed on 401/403
16	Empty test set or empty prompt pack	Pass-rate computed as 0/0 → reported as 100%	§4 and §6 reject zero-row inputs
17	Evidence written to OneDrive / synced folder	Files mutate after hash; manifest tamper	§6 sync-folder probe; §9 re-hash gate
18	Manifest signed before all probes complete	Attestation covers partial evidence	§9 requires non-null `completed_utc` and `overall_exit` before sign
19	`pac pipeline deploy` retried after failure without triage	Drift between dev/test/prod; manifest no longer matches deployed bits	§8 hard-stop on first non-zero
20	Quarterly re-run skipped because "nothing changed"	Module/SKU drift unverified; control silently degrades	§10 quarterly schedule mandatory for Zone 3
21	Evaluator SDK upgraded mid-quarter without re-baselining	Score drift attributed to model when it is evaluator change	§1 pinning + §9 manifest records evaluator versions
22	Content-safety severity averaged across rows instead of max	One severe row hidden in mean → false-clean	§5 uses `max_content_safety_severity`, not mean

Fail-closed conditions:

Any anti-pattern detected at runtime that is not yet caught by a §0–§10 probe → file an issue against this playbook and exit 2 until a probe is added.
