Subject: [PATCH 01/25] fix: prevent azd down from deleting pre-existing
resource groups (#4785, #2916)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Implement a 4-tier resource group classification pipeline in azd down to
distinguish between resource groups created by azd (safe to delete) and
pre-existing resource groups that were merely referenced via Bicep 'existing'
keyword (must not be deleted).
The 4-tier classification pipeline:
- Tier 1: Deployment operations analysis (zero extra API calls) — Create
operations mark RGs as owned, Read/EvaluateDeploymentOutput marks them
as external.
- Tier 2: Dual-tag check (azd-env-name + azd-provision-param-hash) for
RGs with no deployment operations.
- Tier 3: Interactive prompt for remaining unknowns (skipped in CI/--force).
- Tier 4: Safety vetoes (management locks, foreign resources) applied to
ALL deletion candidates including user-accepted unknowns.
Key changes:
- New resource_group_classifier.go with ClassifyResourceGroups function
and comprehensive test coverage (33 tests)
- New bicep_destroy.go with classifyAndDeleteResourceGroups orchestrator
- Restructured BicepProvider.Destroy() to classify before deleting
- Added VoidState to Deployment interface (void after delete, not during)
- Added ResourceGroupsFromDeployment public helper
- Removed unused promptDeletion/generateResourcesToDelete (replaced by
per-RG classification prompts)
Safety properties:
- All API errors treated as vetoes (fail-safe: errors skip deletion)
- --force preserves backward compatibility (bypasses classification)
- Tier 4 prompts executed sequentially (no concurrent terminal output)
- Deployment state voided only after successful classification
- Purge targets collected only from owned (deleted) resource groups
Fixes #4785
Relates to #2916

+# Architecture Design: Multi-Tiered Resource Group Safety for `azd down`
+
+## Overview
+
+### Problem Statement
+
+`azd down` deletes pre-existing resource groups that were merely referenced (via
+Bicep `existing` keyword) but not created by the deployment. This causes
+catastrophic, unrecoverable data loss.
+
+**Root cause**: `resourceGroupsFromDeployment()` in `standard_deployments.go:370`
+extracts ALL resource groups from ARM's `outputResources` and `dependencies`
+fields without distinguishing created-vs-referenced resources.
+`DeleteSubscriptionDeployment()` at line 429 then calls
+`DeleteResourceGroup()` on every discovered RG indiscriminately.
+
+**Real-world impact**: A user with a subscription-scoped Bicep template that
+creates `rg-lego2` for Container Apps and references pre-existing `rg-lego-db`
+(via `existing`) to assign a Cosmos DB role ran `azd down`. Both resource groups
+were deleted — destroying a Cosmos DB account, PostgreSQL Flexible Server, role
+assignments, and the resource group itself. All 25 delete operations share a
+single correlation ID from one `azd down` invocation.
+
+**Permission-dependent behavior**: With `Contributor` role, RG deletion may fail
+(masking the bug). With `Owner` role, it succeeds silently.
+
+### Scope
+
+This design covers the `azd down` command's resource group deletion logic for
+**Standard Deployments** (non-deployment-stacks), including **layered
+provisioning** (multi-layer `azure.yaml` configurations).
+
+**In scope**:
+- `StandardDeployments.DeleteSubscriptionDeployment()` — subscription-scoped
+- `StandardDeployments.DeleteResourceGroupDeployment()` — RG-scoped
+- Layered provisioning (`infra.layers[]` in `azure.yaml`) — cross-layer
+ resource group safety
+- New `ResourceGroupOwnershipClassifier` pipeline
+
+**Out of scope — Deployment Stacks**:
+- `StackDeployments` (`stack_deployments.go`) is **not modified** by this design.
+ Deployment stacks natively track managed vs unmanaged resources via ARM
+ Deployment Stacks and already handle this correctly. Per Decision D5, when
+ `FeatureDeploymentStacks` is enabled, the classification pipeline is
+ bypassed entirely. This design exclusively targets the `StandardDeployments`
+ code path, which is the default behavior for all azd users.
+
+### Constraints
+
+- **No deployment stacks dependency** — the fix must work with the default
+ standard deployment path, not behind an alpha flag
+- **Machine-independent** — must work when `azd up` runs on machine A and
+ `azd down` runs on machine B
+- **Graceful degradation** — must handle deleted deployment data, missing tags,
+ API failures without defaulting to "delete everything"
+- **Backward compatible** — resources provisioned before this change must not
+ become undeletable; the system must degrade gracefully for pre-existing
+ deployments
+- **No new Azure permissions** — must work within the same permission set
+ currently required by `azd down`
+
+## Architecture
+
+### Design Principle: Fail Safe
+
+Every tier's failure mode is **"skip deletion"** — never "delete anyway." The
+only path to deleting a resource group requires positive confirmation from at
+least one ownership tier with no vetoes from the always-on safeguards. The
+correct failure direction for a destructive operation is "we didn't delete
+something we could have" not "we deleted something we shouldn't have."
+
+### Component Design
+
+#### 1. ResourceGroupOwnershipClassifier
+
+**Location**: New type in `cli/azd/pkg/azapi/`
+
+**Responsibility**: Determines whether azd created a given resource group by
+querying multiple signals and producing a classification verdict.
+
+```
+// Actual implementation uses a function-based API:
+
+// ClassifyResult holds the output of ClassifyResourceGroups.
+type ClassifyResult struct {
+ Owned []string // RG names approved for deletion
+ Skipped []ClassifiedSkip // RG names skipped with reasons
+}
+
+type ClassifiedSkip struct {
+ Name string // resource group name
+ Reason string // human-readable explanation (includes tier info)
+}
+
+// ClassifyResourceGroups evaluates each RG through the 4-tier pipeline.
+func ClassifyResourceGroups(
+ ctx context.Context,
+ operations []*armresources.DeploymentOperation,
+ rgNames []string,
+ opts ClassifyOptions,
+) (*ClassifyResult, error)
+```
+
+This classifier runs the 4-tier evaluation pipeline for each resource group
+discovered in the deployment, producing a verdict that the deletion logic uses
+to decide whether to proceed.
+
+#### 2. Enhanced DeleteSubscriptionDeployment
+
+**Location**: Modified method in `standard_deployments.go`
+
+**Responsibility**: Replace the current "delete all RGs" loop with a
+classification-aware loop that only deletes RGs classified as `owned`.
+
+**CRITICAL IMPLEMENTATION NOTE** *(from multi-model review MR-002)*:
+The current `Deployment.Delete()` interface calls
+`DeleteSubscriptionDeployment()`, which **independently re-discovers** all
+RGs via `ListSubscriptionDeploymentResources()` → `resourceGroupsFromDeployment()`
+and deletes them all. The classification result from `BicepProvider.Destroy()`
+would never reach this deletion code. The implementer MUST choose one of:
+
+- **(Recommended) Option A**: Move the per-RG deletion loop OUT of
+ `DeleteSubscriptionDeployment()` into `BicepProvider.Destroy()`, which
+ already has the classified list. `DeleteSubscriptionDeployment()` becomes
+ a thin wrapper that only calls `voidSubscriptionDeploymentState()`.
+ `BicepProvider` calls `DeleteResourceGroup()` directly for each owned RG.
+- **Option B**: Add a `allowedResourceGroups []string` parameter to
+ `DeleteSubscriptionDeployment()` (and update `DeploymentService` interface).
+- **Option C**: Add a new `DeleteFilteredSubscriptionDeployment()` method.
+
+Option A is cleanest because it keeps all classification logic and deletion
+orchestration in `BicepProvider.Destroy()` — the same place that already
+has the deployment, the resources, and the grouped RGs.
+
+The current method:
+1. Lists all resources from deployment
+2. Extracts unique RG names
+3. Deletes every RG
+
+The new method (Option A):
+1. `BicepProvider.Destroy()` calls `deployment.Resources()` (existing)
+2. Groups by RG name (existing)
+3. **Classifies each RG** via ResourceGroupOwnershipClassifier
+4. Deletes only owned RGs by calling `resourceService.DeleteResourceGroup()`
+ directly
+5. Reports skipped RGs to the progress callback
+6. Calls `voidSubscriptionDeploymentState()` ONLY after all intended
+ deletions succeed (see MR-008 partial failure fix)
+
+#### 3. Enhanced Destruction Preview
+
+**Location**: Modified `promptDeletion()` in `bicep_provider.go`
+
+**Responsibility**: Show users which resource groups will be deleted vs. skipped,
+with clear provenance labels.
+
+Current behavior: Shows a flat list of resources and asks "are you sure?"
+
+New behavior: Groups resources by RG, labels each RG with its classification
+(`azd-created` / `pre-existing` / `unknown`), and shows separate counts for
+each category. For `unknown` RGs in interactive mode, prompts per-RG.
+
+### Data Flow
+
+```

+ │
+ ├─ BicepProvider.Destroy()
+ │ │
+ │ ├─ CompletedDeployments() ─── find most recent deployment
+ │ │
+ │ ├─ deployment.Resources() ─── get all resources (existing behavior)
+ │ │
+ │ ├─ GroupByResourceGroup() ─── group resources by RG name
+ │ │
+ │ ├─ *** NEW: ClassifyResourceGroups() ***
+ │ │ │
+ │ │ ├─ [Tier 1: Deployment Operations] ─── highest confidence (zero API calls)
+ │ │ │ ├─ Scan deployment.Operations()
+ │ │ │ ├─ Create op on RG? → classified "owned"
+ │ │ │ ├─ Read/EvaluateDeploymentOutput op? → classified "external" → SKIP
+ │ │ │ └─ No ops at all? → classified "unknown" → fall to Tier 2
+ │ │ │
+ │ │ ├─ [Tier 2: Tag Verification] ─── only for "unknown" RGs
+ │ │ │ ├─ Check RG for BOTH azd-env-name AND azd-provision-param-hash tags
+ │ │ │ ├─ Both tags present and azd-env-name matches? → classified "owned"
+ │ │ │ └─ Tags missing or mismatched? → fall to Tier 3
+ │ │ │
+ │ │ ├─ [Tier 3: Interactive Confirmation] ─── runs BEFORE Tier 4
+ │ │ │ ├─ In interactive mode: prompt user per-RG with warning (default: No)
+ │ │ │ │ "azd did not create resource group 'X'. Delete it? (y/N)"
+ │ │ │ ├─ User accepts → merged into owned list for Tier 4 veto checks
+ │ │ │ └─ Non-interactive/--force: classify as "external" (NEVER deleted)
+ │ │ │
+ │ │ └─ [Tier 4: Always-On Safeguards] ─── runs on ALL deletion candidates
+ │ │ ├─ Has CanNotDelete/ReadOnly lock? → SKIP (veto, best-effort)
+ │ │ ├─ Contains resources NOT in deployment (without matching
+ │ │ │ azd-env-name tag)? → soft veto (prompt if interactive)
+ │ │ └─ API errors (500, 429, etc.) → treated as veto (fail-safe)
+ │ │
+ │ ├─ Enhanced promptDeletion() ─── show classified preview
+ │ │ ├─ "WILL DELETE: rg-app (azd-created, Tier 1: deployment operations)"
+ │ │ ├─ "SKIPPING: rg-shared-db (pre-existing, Tier 1: Read operation only)"
+ │ │ ├─ Per-RG prompt for external/unknown RGs in interactive mode
+ │ │ └─ Confirm deletion of owned resources
+ │ │
+ │ ├─ destroyDeployment() ─── delete only owned RGs
+ │ │ ├─ Delete RGs classified as "owned" (or user-approved in interactive mode)
+ │ │ ├─ Skip RGs classified as "external" or "unknown"
+ │ │ ├─ Emit structured telemetry event per classification decision
+ │ │ └─ Log all skip decisions for audit
+ │ │
+ │ ├─ Purge flow ─── ONLY for resources in non-skipped RGs
+ │ │ ├─ Filter out Key Vaults/Cognitive/AppConfig in skipped RGs
+ │ │ └─ Purge only resources in deleted RGs
+ │ │
+ │
+ └─ Void deployment state (existing behavior)
+```
+
+## Patterns & Decisions
+
+### Decision 1: Multi-Tier Classification over Single-Signal Ownership
+
+**Pattern**: Defense in depth / Chain of responsibility
+
+**Why**: Every individual ownership signal has a fatal flaw when used alone:
+
+| Signal | Fatal Flaw |
+|--------|-----------|
+| ARM deployment operations | Gone if deployment data deleted from Azure |
+| azd tags | User-writable; can be spoofed or manually added |
+| Local state file | Not portable across machines |
+| RG creation timestamp | Approximate; race conditions possible |
+| Resource locks | Opt-in; most users don't set them |
+
+By layering signals, the system tolerates any single signal being unavailable
+or compromised. The key insight is that each tier's failure mode is "skip"
+(safe) not "delete" (unsafe).
+
+**Evaluation order**: Tier 4 (always-on vetoes) runs first because it can
+immediately exclude RGs regardless of what other tiers say. Then Tier 1
+(highest confidence) through Tier 3 (lowest confidence) run in sequence,
+stopping at the first tier that produces a definitive answer.
+
+### Decision 2: Deployment Operations as Primary Signal (Tier 1)
+
+**Pattern**: Leverage existing infrastructure
+
+**Why**: The `Deployment.Operations()` method already exists in `scope.go:66`
+and calls `ListSubscriptionDeploymentOperations()`. ARM deployment operations
+include a `provisioningOperation` field with values including `Create`, `Read`,
+`EvaluateDeploymentOutput`, etc. Resources referenced via Bicep `existing`
+keyword produce `Read` or `EvaluateDeploymentOutput` operations — never
+`Create`. This is the single highest-confidence signal available.
+
+**How it works**:
+1. Call `deployment.Operations(ctx)` to get all deployment operations
+2. Build a set of resource group names where an operation exists with:
+ - `provisioningOperation == "Create"`
+ - `targetResource.resourceType == "Microsoft.Resources/resourceGroups"`
+3. Any RG in this set is classified as `owned`
+4. Any RG with an explicit `Read` or `EvaluateDeploymentOutput` operation
+ (but no `Create`) is classified as `external` — this is the high-confidence
+ signal that the RG was referenced via Bicep `existing`
+5. Any RG with NO operations at all is classified as `unknown` — NOT
+ `external`. This handles: (a) nested Bicep module deployments where
+ top-level operations don't flatten RG creates (see MR-004), (b)
+ partially purged operation history. `unknown` falls through to Tier 2.
+
+**IMPORTANT** *(from multi-model review MR-004)*: ARM does NOT flatten
+nested deployment operations. If an RG is created inside a Bicep module
+(not at the top level of `main.bicep`), the top-level operations will
+show the module as `Microsoft.Resources/deployments` with no direct
+`Create` for the RG. The implementer should either:
+- Recursively walk nested deployment operations (check for
+ `TargetResource.ResourceType == "Microsoft.Resources/deployments"`
+ and query that sub-deployment's operations)
+- Or classify as `unknown` (not `external`) and let Tier 2 handle it
+
+Standard azd templates declare RGs at top level, so this primarily affects
+user-customized templates. The `unknown` classification is the safe default.
+
+**When it fails**: If deployment history has been purged from Azure (ARM retains
+up to 800 deployments per scope). In this case, fall through to Tier 2.
+
+### Decision 3: Dual-Tag Verification as Fallback (Tier 2)
+
+**Pattern**: Multi-factor verification
+
+**Why**: azd already applies `azd-env-name` tags during provisioning. By
+checking for BOTH `azd-env-name` AND `azd-provision-param-hash` tags, we
+reduce false positives — it is unlikely (though not impossible) that a user
+manually adds both tags with correct values.
+
+**Important**: Tags alone are never sufficient for deletion — this tier only
+activates when Tier 1 is unavailable (deployment operations API returns error
+or empty). Tags are a necessary-but-not-sufficient signal, strengthened by
+requiring two matching tags rather than one.
+
+### Decision 4: --force Bypasses Classification Entirely
+
+**Pattern**: Explicit override for CI/CD and automation
+
+**Why**: `--force` is used in CI/CD pipelines and scripts where operators accept
+full responsibility for teardown. In the new design, `--force` bypasses the
+entire 4-tier classification pipeline and deletes ALL resource groups from
+the deployment, matching the original behavior. Classification only runs in
+interactive mode (without `--force`). In non-interactive mode
+(`--force`, CI/CD), ALL referenced RGs are deleted — the operator is expected
+to manage scope via their Bicep templates.
+
+**Note**: A future enhancement could make `--force` run the free Tier 1 check
+(zero API calls) and still skip external RGs, but this is deferred to avoid
+breaking existing CI/CD workflows that depend on the current behavior.
+
+No `--delete-resource-groups` or similar bulk override flag exists. This is
+a deliberate design choice: azd will never delete a resource group it didn't
+create without per-RG human consent.
+
+### Decision 5: Always-On Safeguards as Veto Layer (Tier 4)
+
+**Pattern**: Circuit breaker / Invariant checks
+
+**Why**: Certain conditions should ALWAYS prevent deletion regardless of what
+ownership signals say. These are hard vetoes that override all other tiers:
+
+1. **Resource locks** *(best-effort)*: If an RG has a `CanNotDelete` or `ReadOnly`
+ lock, it was explicitly protected by someone. Attempting to delete it will
+ fail anyway — better to skip it proactively. **Important**: The lock check
+ requires `Microsoft.Authorization/locks/read` permission which azd does not
+ currently require. Per the "no new permissions" constraint, this check is
+ **best-effort**: if the API returns 403, skip the lock check sub-tier
+ entirely (do NOT veto) and log a warning. Alternatively, the implementer
+ may omit this check and let ARM's own lock enforcement produce a clear
+ error at `DeleteResourceGroup` time.
+
+2. **Extra resources**: If an RG contains resources that are NOT in the
+ deployment's resource list AND do not have an `azd-env-name` tag matching
+ the current environment, it likely contains resources from other
+ deployments or manual provisioning. Deleting the RG would destroy those
+ resources as collateral damage. Resources from sibling layers (which share
+ the same `azd-env-name` tag) are NOT counted as extra — this enables
+ correct behavior in layered provisioning scenarios (see "Layered
+ Provisioning Support" section).
+
+3. **~~Timestamp heuristic~~** *(REMOVED — see Multi-Model Review MR-001)*:
+ The original design proposed vetoing when `RG.createdTime < deployment.Timestamp`.
+ Multi-model review (Opus, Codex, Goldeneye — all 3 independently) identified
+ this as critically flawed: on any re-deployment, the RG was created during the
+ *first* `azd up` while the deployment timestamp reflects the *latest* `azd up`,
+ so the comparison is always true for re-provisioned environments. Additionally,
+ ARM SDK does not expose `createdTime` without raw REST `$expand=createdTime`.
+ **This sub-tier is removed entirely.** Tiers 1 and 2 plus lock/extra-resource
+ checks provide sufficient safety without this fragile heuristic.
+
+## Layered Provisioning Support
+
+### Background
+
+azd supports **layered provisioning** where `azure.yaml` defines multiple
+infrastructure layers under `infra.layers[]`. Each layer is a separate Bicep
+(or Terraform) module with its own ARM deployment. During `azd down`, layers
+are processed in **reverse order** — the last layer provisioned is the first
+layer destroyed (`slices.Reverse(layers)` in `down.go:134`).
+
+Each layer gets:
+- Its own deployment name: `{envName}-{layerName}`
+- Its own ARM deployment with tags: `azd-env-name`, `azd-layer-name`,
+ `azd-provision-param-hash`
+- Its own independent `provisionManager.Initialize()` + `Destroy()` cycle
+
+### Cross-Layer Resource Group Scenarios
+
+The classification pipeline runs per-layer (each layer processes independently).
+The reverse ordering creates important interactions:
+
+**Scenario 1: Layer 1 creates RG, Layer 2 references it via `existing`**
+
+Processing order: Layer 2 first, then Layer 1.
+
+1. Layer 2: Tier 1 checks deployment operations → RG has `Read` operation
+ (not `Create`) → classified as `external` → **SKIP**
+2. Layer 1: Tier 1 checks deployment operations → RG has `Create` operation
+ → classified as `owned` → **DELETE**
+
+Result: Correct. The creating layer deletes the RG after the referencing
+layer has been processed.
+
+**Scenario 2: Both layers reference a pre-existing RG**
+
+1. Layer 2: classified as `external` → SKIP
+2. Layer 1: classified as `external` → SKIP
+
+Result: Correct. Pre-existing RG is preserved.
+
+**Scenario 3: Layer 1 creates RG, Layer 2 deploys resources into it**
+
+This is the complex case. Layer 2 processes first and skips the RG (correct).
+When Layer 1 processes, the RG contains resources from both layers. Layer 2's
+resources are still present because the RG was not deleted.
+
+Without cross-layer awareness, Tier 4's extra-resource check would find
+Layer 2's resources and veto deletion — even though Layer 1 legitimately
+created the RG.
+
+**Solution: azd-env-name-aware extra-resource check**
+
+The Tier 4 extra-resource check is refined to distinguish truly foreign
+resources from sibling-layer resources:
+
+- Query the RG's actual resources via `ListResourceGroupResources()`
+- For each resource NOT in the current layer's deployment resource list:
+ - Check if the resource has an `azd-env-name` tag matching the current
+ environment name
+ - If YES: the resource belongs to a sibling layer or this deployment —
+ it is NOT counted as "extra"
+ - If NO: the resource is truly foreign (manually created, from another
+ deployment, etc.) — it IS counted as "extra" and triggers the veto
+
+This approach:
+- Requires no pre-scan pass across layers
+- Works because azd tags resources with `azd-env-name` during provisioning
+- Correctly identifies resources from sibling layers as "safe"
+- Still catches truly foreign resources (those without azd tags or with a
+ different environment name)
+
+**Scenario 3 with the fix**:
+
+1. Layer 2: Tier 1 → `external` → SKIP
+2. Layer 1: Tier 1 → `owned`. Tier 4 extra-resource check finds Layer 2's
+ resources, but they have `azd-env-name` matching the current env →
+ NOT counted as extra → no veto → **DELETE**
+
+Result: Correct. The RG is deleted by the layer that created it, and
+sibling-layer resources are recognized as part of the same deployment
+environment.
+
+### Layer-Specific Deployment Name Resolution
+
+Each layer's deployment has a unique name (`{envName}-{layerName}`). The
+classifier uses the deployment associated with the current layer being
+processed. This means:
+
+- Tier 1 queries operations from the CURRENT layer's deployment only
+- Tier 2 checks tags on the RG (layer-agnostic — `azd-env-name` is shared
+ across layers)
+- Tier 4's extra-resource check uses the azd-env-name-aware logic above
+
+No changes are needed to the layer iteration loop in `down.go`. The
+classification pipeline is fully layer-compatible by design.
+
+## Gap Remediation
+
+### 🚫 Anti-Pattern: Unfiltered Resource Group Deletion (Critical)
+
+**Current code** (`standard_deployments.go:429-476`):
+```go
+for resourceGroup := range resourceGroups {
+ if err := ds.resourceService.DeleteResourceGroup(ctx, subscriptionId, resourceGroup); err != nil {
+ // ...
+ }
+}
+```
+
+**Fix**: Replace with classification-aware deletion:
+```go
+for _, classified := range classifiedGroups {
+ if classified.Classification != ClassificationOwned {
+ progress.SetProgress(DeleteDeploymentProgress{
+ Name: classified.Name,
+ Message: fmt.Sprintf("Skipping resource group %s (%s)",
+ output.WithHighLightFormat(classified.Name), classified.Reason),
+ State: DeleteResourceStateSkipped,
+ })
+ continue
+ }
+ // ... existing delete logic for owned RGs
+}
+```
+
+This requires adding a `DeleteResourceStateSkipped` state to the existing
+`DeleteResourceState` enum.
+
+### 🚫 Anti-Pattern: Operations() Never Used in Destroy Path (Critical)
+
+**Current state**: `Deployment.Operations()` exists in `scope.go:66` and is
+fully functional, but `BicepProvider.Destroy()` only calls
+`deployment.Resources()` — never `deployment.Operations()`.
+
+**Fix**: In the new classification pipeline, call `deployment.Operations()`
+to retrieve deployment operations and filter by `provisioningOperation`.
+
+### ⚠️ Gap: No Resource Lock Check (High)
+
+**Current state**: `DeleteResourceGroup()` in `resource_service.go:297` calls
+ARM's `BeginDelete` directly. If the RG has a lock, this fails with an error
+mid-operation — potentially after other RGs have already been deleted.
+
+**Fix**: Before entering the deletion loop, query locks for each candidate RG
+via the ARM management locks API. Skip locked RGs proactively.
+
+### ⚠️ Gap: --force Bypasses All Safety (High)
+
+**Current state** (`bicep_provider.go:1238`):
+```go
+if options.Force() {
+ return nil
+}
+```
+
+**Fix**: `--force` should only skip the interactive confirmation prompt for
+RGs classified as `owned`. It should NOT skip the ownership classification,
+and it should NOT allow deletion of external/unknown RGs. The classification
+pipeline runs regardless of `--force`. For `external` or `unknown` resources
+in `--force` mode, the RG is unconditionally skipped (never deleted). In
+interactive mode without `--force`, the user is prompted per-RG with a
+default of No.
+
+### ⚠️ Gap: No Extra-Resource Detection (Medium)
+
+**Current state**: `ListSubscriptionDeploymentResources()` calls
+`ListResourceGroupResources()` to get all resources in each RG, but only uses
+the result to build the deletion list. It never compares the RG's actual
+contents against the deployment's expected contents.
+
+**Fix**: Compare the resource IDs returned by `ListResourceGroupResources()`
+against the resource IDs in the deployment's `Resources()`. If the RG contains
+resources not in the deployment, flag it as a veto in Tier 4.
+
+### 🔄 Modernization: DeleteResourceGroupDeployment Parity (Medium)
+
+**Current state**: `DeleteResourceGroupDeployment()` at line 521 also deletes
+the RG unconditionally. For RG-scoped deployments, this is less dangerous
+(the RG is the deployment scope itself), but the same safety checks should
+apply.
+
+**Fix**: Apply the same classification pipeline to RG-scoped deletions.
+Since there is only one RG in this case, the classification is simpler but
+should still check for locks and extra resources.
+
+## Risks & Trade-offs
+
+### Risk 1: Deployment Operations Unavailable for Old Deployments
+
+**Severity**: Medium
+
+**Description**: ARM has a retention limit of 800 deployments per scope. For
+very old deployments, operations data may have been purged. The Tier 1 signal
+would be unavailable.
+
+**Mitigation**: Fall through to Tier 2 (tag check). For deployments created
+before this change, both Tier 1 and Tier 2 may be degraded. In that case,
+Tier 3 (interactive confirmation) activates. For `--force` mode with old
+deployments, RGs with unknown provenance are skipped with a logged warning
+recommending re-provisioning (`azd provision`) to establish ownership signals.
+
+### Risk 2: Performance Impact of Additional API Calls
+
+**Severity**: Low
+
+**Description**: The classification pipeline adds API calls: deployment
+operations list, resource group metadata (tags, locks, timestamps). For a
+deployment with N resource groups, this adds O(N) API calls.
+
+**Mitigation**: N is typically small (1-5 RGs). The deployment operations
+call is a single paginated request regardless of N. RG metadata queries can
+be parallelized. The total added latency should be <5 seconds for typical
+deployments. This is acceptable for a destructive operation where safety
+trumps speed.
+
+### Risk 3: False Negatives (Refusing to Delete an azd-Created RG)
+
+**Severity**: Medium
+
+**Description**: The multi-tier system may incorrectly classify an
+azd-created RG as `unknown` or `external` if: (a) deployment operations
+are purged, (b) tags were removed by another process, (c) the RG was
+recreated outside azd after initial provisioning.
+
+**Mitigation**: In interactive mode, `external` and `unknown` both trigger a
+per-RG prompt — the user can explicitly approve deletion with a conscious
+decision (default is No). In `--force` mode, the warning log tells users to
+run `azd provision` first to re-establish ownership signals. There is no
+bulk override flag — each external RG must be individually approved.
+
+### Risk 4: Backward Compatibility with Existing Deployments
+
+**Severity**: Medium
+
+**Description**: Users who have been running `azd down` successfully (because
+they only have azd-created RGs) should see no change in behavior. Users whose
+deployments reference pre-existing RGs will see new behavior (those RGs are
+now skipped).
+
+**Mitigation**: The new behavior is strictly safer — it only reduces the set
+of RGs that get deleted, never expands it. Existing workflows where all RGs
+are azd-created will classify as `owned` via Tier 1 and proceed normally.
+The only change users will notice is that pre-existing RGs are now preserved
+(which is the correct behavior).
+
+### Risk 5: Tag Spoofing in Tier 2
+
+**Severity**: Low
+
+**Description**: A malicious actor could add `azd-env-name` and
+`azd-provision-param-hash` tags to a victim resource group, causing azd
+to classify it as "owned" and delete it.
+
+**Mitigation**: Tier 2 only activates when Tier 1 is unavailable. When both
+tiers are active, Tier 1 takes precedence. Additionally, Tier 4's
+extra-resource check would likely catch this scenario — the victim RG would
+contain resources not in the deployment. Tag spoofing requires write access
+to the victim RG, which implies the attacker already has significant
+privileges.
+
+## Resolved Design Decisions
+
+### D1: No Bulk Override Flag — Per-RG Consent Only
+
+**Decision**: There is NO flag combination that bulk-deletes external resource
+groups. azd will NEVER delete a resource group it didn't create unless the user
+explicitly approves each one individually in an interactive session.
+
+**Flag behavior**:
+- `--force` — Skips confirmation prompts for azd-CREATED resource groups only.
+ Has zero effect on external/unknown RGs.
+- `--purge` — Unchanged (soft-delete purging only).
+- No new flags are added.
+
+**Behavior by mode**:
+- **Interactive**: Per-RG prompt with explicit warning and default No:
+ `"azd did not create resource group 'rg-shared-db'. Delete it? (y/N)"`
+- **Non-interactive (CI/CD, --force)**: External/unknown RGs are NEVER deleted.
+ Logged as skipped with classification reason.
+
+### D2: Structured Telemetry for Classification Decisions
+
+**Decision**: Emit structured telemetry events for every classification
+decision. Each event includes: resource group name, classification result
+(owned/external/unknown), tier that produced the verdict, reason string,
+and deployment name. This enables debugging user support tickets and
+measuring the safety system's effectiveness.
+
+### D3: Full Pipeline for RG-Scoped Deployments
+
+**Decision**: `DeleteResourceGroupDeployment()` runs the same full 4-tier
+classification pipeline as subscription-scoped deployments. Even though the
+RG is the deployment scope itself (and was typically created before
+`azd provision`), the classification will correctly identify it as external
+via Tier 1 (no `Create` operation for the RG in deployment operations) and
+prompt the user accordingly.
+
+### D4: Skip Purge for Resources in Skipped RGs
+
+**Decision**: When a resource group is classified as external and skipped
+during deletion, the purge flow (Key Vaults, Cognitive Services, App
+Configurations, API Management, Log Analytics Workspaces) also skips
+resources within that RG. The purge flow receives the set of skipped RG
+names and filters them out.
+
+### D5: Skip Classification When Deployment Stacks Active
+
+**Decision**: When the `FeatureDeploymentStacks` alpha flag is enabled and
+the deployment uses the `StackDeployments` code path, the classification
+pipeline is bypassed. Deployment stacks natively track managed vs unmanaged
+resources and handle this correctly. The classification pipeline only runs
+for `StandardDeployments`.
+
+### D6: Extra-Resource Veto (azd-env-name-aware, soft in interactive mode)
+
+**Decision**: The Tier 4 extra-resource check uses an absolute threshold:
+if a resource group contains ANY resource that is (a) not present in the
+current layer's deployment resource list AND (b) does not have an
+`azd-env-name` tag matching the current environment, the Tier 4 veto
+triggers. Resources from sibling layers (which share the same
+`azd-env-name` tag) are excluded from the "extra" count — this prevents
+false vetoes in layered provisioning scenarios. See the "Layered
+Provisioning Support" section for detailed scenario analysis.
+
+**Interactive mode refinement** *(from multi-model review MR-010)*: In
+interactive mode (no `--force`), the extra-resource veto is a **soft veto**:
+the user is shown the foreign resources and asked for explicit per-RG
+confirmation (default No). This handles the common case where users manually
+add experimental resources to azd-managed RGs. In `--force`/CI mode, the
+veto remains **hard** — foreign resources unconditionally block deletion.

+
+## Multi-Model Review Findings
+
+This design was reviewed by three independent AI models (Claude Opus 4.6,
+GPT-5.3-Codex, Goldeneye) acting as hostile critics. Below are the merged,
+deduplicated findings with their resolutions. Each finding ID uses `MR-NNN`
+(Merged Review) with the originating model(s) noted.
+
+### MR-001 [CRITICAL] — Timestamp Veto Breaks All Re-Deployment Scenarios
+**Models**: [Opus] [Codex] [Goldeneye] — unanimous consensus
+
+**Problem**: The Tier 4 rule `RG.createdTime < deployment.Timestamp → SKIP`
+is always true for re-provisioned environments. On first `azd up` (Monday),
+RG is created. On second `azd up` (Friday), deployment timestamp updates.
+`azd down` (Saturday): Monday < Friday → VETO. Every re-deployed azd
+environment becomes undeletable.
+
+Additionally, ARM SDK's `ResourceGroupProperties` does not expose
+`createdTime`; it requires raw REST `$expand=createdTime` (not in typed SDK).
+
+**Resolution**: **Removed entirely**. The timestamp sub-tier has been deleted
+from Tier 4. The remaining checks (locks + extra-resource) combined with
+Tiers 1-3 provide sufficient safety. Timestamps are too fragile and
+require SDK workarounds.
+
+### MR-002 [CRITICAL] — Classification Result Never Reaches Deletion Code
+**Models**: [Opus]
+
+**Problem**: `BicepProvider.Destroy()` calls `deployment.Delete()` →
+`DeleteSubscriptionDeployment()`, which independently re-discovers ALL RGs
+and deletes them. The classification result is architecturally disconnected
+from the code that performs deletion. Without restructuring, classification
+is dead code.
+
+**Resolution**: **Design updated** (see "Enhanced DeleteSubscriptionDeployment"
+section). Recommended approach: move the per-RG deletion loop from
+`DeleteSubscriptionDeployment()` into `BicepProvider.Destroy()`, which
+already has the classified list. `BicepProvider` calls
+`resourceService.DeleteResourceGroup()` directly for owned RGs. The
+`DeleteSubscriptionDeployment()` method becomes a thin wrapper for
+`voidSubscriptionDeploymentState()` only.
+
+### MR-003 [HIGH] — Purge Targets Computed Before Classification
+**Models**: [Goldeneye]
+
+**Problem**: `BicepProvider.Destroy()` computes Key Vault / Managed HSM /
+App Config / APIM / Cognitive / Log Analytics purge targets BEFORE the
+classification step. If an RG is later classified as external and skipped,
+its resources are still in the purge lists. D4 says "skip purge for skipped
+RGs" but the current data flow doesn't enforce this.
+
+**Resolution**: Purge target collection must happen AFTER classification, or
+the purge lists must be filtered against the `skippedRGs` set before
+execution. The implementer should:
+1. Run classification first
+2. Filter `groupedResources` to owned-only RGs
+3. Then compute purge targets from the filtered set
+This is a natural consequence of MR-002's restructuring.
+
+### MR-004 [HIGH] — Deployment Operations Not Flattened for Nested Modules
+**Models**: [Opus]
+
+**Problem**: ARM does NOT flatten nested deployment operations. If an RG is
+created inside a Bicep module, the top-level operations show the module as
+a `Microsoft.Resources/deployments` operation — no `Create` for
+`Microsoft.Resources/resourceGroups` appears at the top level.
+
+Standard azd templates declare RGs at top level (not affected), but
+user-customized templates may use module-based patterns.
+
+**Resolution**: **Design updated** (see Decision 2). Tier 1 now classifies
+as `unknown` (not `external`) when no operations of any kind are found for
+an RG, allowing fallback to Tier 2. The implementer may optionally add
+recursive operation walking for nested deployments.
+
+### MR-005 [HIGH] — Lock Check Requires New Azure Permissions
+**Models**: [Opus]
+
+**Problem**: The lock check calls `Microsoft.Authorization/locks` API which
+requires `Microsoft.Authorization/locks/read` permission. azd does not
+currently require this. Violates the "no new permissions" constraint.
+
+**Resolution**: **Design updated** — lock check is now **best-effort**. If
+the API returns 403 Forbidden, skip the lock sub-tier (do NOT veto) and log
+a warning. Alternatively, the implementer may omit the lock check entirely
+— ARM's own lock enforcement produces a clear error at deletion time.
+
+### MR-006 [HIGH] — `--force` + Degraded Tiers = Permanently Undeletable in CI
+**Models**: [Opus]
+
+**Problem**: When Tier 1 is unavailable (deployment history purged) AND
+Tier 2 fails (tags missing), Tier 3 in `--force` mode classifies as
+`external` → never deleted. D1 prohibits any override flag. CI/CD
+pipelines that use `azd down --force` for teardown silently fail to delete
+owned RGs, accumulating orphans.
+
+**Resolution**: Accept this as a deliberate safety trade-off — it's better
+to orphan RGs in CI than to risk deleting production databases. Add a clear
+log message: "Resource group 'X' could not be verified as azd-created.
+Run `azd provision` to re-establish ownership signals, then retry
+`azd down`." The `azd provision` path will create fresh deployment
+operations (Tier 1) and tags (Tier 2), enabling successful deletion.
+
+### MR-007 [HIGH] — RG-Scoped Deployments Lack Equivalent Evidence
+**Models**: [Goldeneye]
+
+**Problem**: D3 applies the full pipeline to RG-scoped deployments, but the
+evidence model is different. In RG-scoped deployments, the RG IS the
+deployment scope — there is no "RG Create operation" in deployment operations
+because the RG is the container, not a deployed resource. The current
+`DeleteResourceGroupDeployment()` directly deletes without enumeration.
+
+**Resolution**: For RG-scoped deployments, modify the pipeline:
+- Tier 1: Check if the deployment operations contain ANY `Create` operations
+ for resources inside the RG. If yes, azd deployed into this RG → `owned`.
+ If the RG was created OUTSIDE azd (e.g., user created it manually and set
+ `AZURE_RESOURCE_GROUP`), there will be no deployment history → `unknown`.
+- Tier 2: Same tag check applies (RG tags).
+- Tier 4 extra-resource check: Compare deployment resources against actual
+ RG contents (same logic).
+- Tier 3: Interactive prompt as normal.
+
+### MR-008 [HIGH] — Void Deployment State Destroys Evidence on Partial Failure
+**Models**: [Opus] [Goldeneye]
+
+**Problem**: After deleting RGs, `voidSubscriptionDeploymentState()` deploys
+an empty template that becomes the most recent deployment. On partial failure
+(e.g., 2 of 3 RGs deleted), the void deployment is created. Retry finds the
+void deployment (no resources, no operations) → "No resources found." The
+surviving RG is orphaned.
+
+**Resolution**: **Defer voiding until ALL intended deletions succeed.** If
+any deletion fails, do NOT void the deployment state. This preserves
+Tier 1 evidence for retry. The implementer should:
+1. Delete all owned RGs first (collecting errors)
+2. Only call `voidSubscriptionDeploymentState()` if all deletions succeeded
+3. On partial failure, return the error without voiding — user can retry
+ `azd down` and the classification will work correctly
+
+### MR-009 [HIGH] — `--force` Can Bypass if Classification Attached to Prompting
+**Models**: [Goldeneye]
+
+**Problem**: Existing `promptDeletion()` returns `nil` immediately when
+`options.Force()` is true. If any safety logic is placed in or after the
+prompt path, `--force` bypasses it entirely.
+
+**Resolution**: Classification MUST run unconditionally — before any
+prompt logic. The `--force` flag only controls whether the interactive
+confirmation prompt is shown for owned RGs. The classification pipeline
+(Tiers 4/1/2) runs regardless of `--force`. Tier 3 only activates
+in interactive mode.
+
+### MR-010 [MEDIUM] — Tier 4 Absolute Veto Blocks Interactive User Override
+**Models**: [Opus]
+
+**Problem**: Users who manually add experimental resources to azd-managed
+RGs find `azd down` refuses to clean up. The veto is absolute with no
+override path, even in interactive mode.
+
+**Resolution**: **Design updated** (see D6). In interactive mode, the
+extra-resource veto is a soft veto — user is shown the foreign resources
+and prompted per-RG. In `--force`/CI mode, it remains a hard veto.
+
+### MR-011 [MEDIUM] — Failed Deployment Cleanup Path Differs from Succeeded
+**Models**: [Goldeneye]
+
+**Problem**: `resourceGroupsFromDeployment()` has two branches: succeeded
+(uses `outputResources`) and failed (uses `dependencies`). These carry
+different fidelity. The failed path is exactly when `azd down` is most
+needed.
+
+**Resolution**: The classifier must handle both paths. For failed
+deployments:
+- `deployment.Operations()` may be partially populated — use what's
+ available
+- `deployment.Dependencies` may include RGs that were never actually
+ created — Tier 1 would show no `Create` op → correctly classified as
+ `unknown`/`external`
+- Add explicit tests for: fail-before-RG-create, fail-after-RG-create,
+ canceled deployment, and partial Operations() availability
+
+### MR-012 [MEDIUM] — Terraform Provider Not Covered
+**Models**: [Goldeneye]
+
+**Problem**: The design is ARM/Bicep-centric. azd supports Terraform where
+ownership signals come from Terraform state, not ARM deployment operations.
+
+**Resolution**: This design targets the Bicep provider (`bicep_provider.go`)
+which is the primary path. Terraform's destroy path uses `terraform destroy`
+which has its own state management. Add to Scope section: "Terraform
+provider is out of scope for this design — Terraform's state-based
+destruction already tracks which resources it manages." Future work may
+add a provider-neutral classification contract.
+
+### MR-013 [MEDIUM] — TOCTOU Window Between Classification and Deletion
+**Models**: [Codex]
+
+**Problem**: Locks/tags/resources can change between classification and
+deletion. External actors or parallel azd runs could modify state.
+
+**Resolution**: Accept as inherent to any non-transactional system.
+Mitigation: classify ALL RGs before deleting ANY (batch classification,
+then batch deletion). This minimizes the window. ARM's own lock
+enforcement provides a final safety net at deletion time.
+
+### MR-014 [MEDIUM] — ARM Throttling and Permission Edge Cases
+**Models**: [Codex] [Goldeneye]
+
+**Problem**: New API calls (operations, locks, resource enumeration) risk
+ARM 429 throttling and custom RBAC roles may allow deletion but not reads.
+
+**Resolution**: Implement retry with exponential backoff + jitter for all
+ARM calls. Distinguish 403 (skip check, log warning) from 429 (retry)
+from 5xx (retry with backoff). Use goroutines with a semaphore for parallel
+per-RG Tier 4 checks. See Implementation Guide.
+
+### MR-015 [LOW] — ARM SDK Pointer Types Require Nil Guards
+**Models**: [Opus]
+
+**Problem**: `DeploymentOperationProperties.ProvisioningOperation`,
+`TargetResource`, and `TargetResource.ResourceType` are all pointer types.
+Existing tests set `ProvisioningState` but not these fields, confirming
+they can be nil.
+
+**Resolution**: Mandate nil checks for all pointer fields before comparison.
+Skip operations where any required field is nil. See Implementation Guide.
+
+### MR-016 [LOW] — Per-RG Prompting UX at Scale
+**Models**: [Goldeneye]
+
+**Problem**: Per-RG prompts don't scale for 10+ RGs across layers.
+
+**Resolution**: Show a summary table of all classification decisions first:
+```
+Resource Groups to delete:
+ ✓ rg-app (azd-created, Tier 1)
+ ✓ rg-web (azd-created, Tier 1)
+ ✗ rg-shared-db (pre-existing, skipped)
+ ? rg-experiment (unknown — contains 2 extra resources)
+```
+Then prompt ONCE for the unknown set: "Delete 1 unverified resource group?
+(y/N)" For owned RGs, show total count and confirm once (unless `--force`).
+
+### MR-017 [LOW] — Go Concurrency Footgun in Parallel Checks
+**Models**: [Codex]
+
+**Problem**: Parallel per-RG metadata queries writing to shared maps/slices
+can cause `concurrent map writes` panics.
+
+**Resolution**: Use immutable per-worker results + channel fan-in pattern.
+Each goroutine returns its `ClassifiedResourceGroup` via a channel. The
+collector assembles the final slice. Run with `-race` in CI. See
+Implementation Guide.
+
+## Implementation Guide for Developers
+
+### Tip 1: Restructure the Deletion Flow (MR-002 — CRITICAL, do this first)
+
+The single most important structural change: move the deletion loop from
+`DeleteSubscriptionDeployment()` into `BicepProvider.Destroy()`.
+
+```
+Current flow:
+ BicepProvider.Destroy() → deployment.Delete() → DeleteSubscriptionDeployment()
+ → re-discovers RGs → deletes ALL
+
+New flow:
+ BicepProvider.Destroy()
+ → deployment.Resources() (already called)
+ → GroupByResourceGroup() (already called)
+ → ClassifyResourceGroups() (NEW)
+ → for each owned RG: resourceService.DeleteResourceGroup()
+ → voidSubscriptionDeploymentState() (only if all succeeded)
+```
+
+`deployment.Delete()` should be refactored or a new path created. The
+classifier needs access to `deployment.Operations()` and
+`resourceService.ListResourceGroupResources()` — pass these as
+dependencies to the classifier constructor.
+
+### Tip 2: ARM SDK Nil Guard Pattern
+
+Every field access on `DeploymentOperation` must be guarded:
+
+```go
+for _, op := range operations {
+ if op.Properties == nil ||
+ op.Properties.ProvisioningOperation == nil ||
+ op.Properties.TargetResource == nil ||
+ op.Properties.TargetResource.ResourceType == nil ||
+ op.Properties.TargetResource.ResourceName == nil {
+ continue // skip incomplete operations
+ }
+ if *op.Properties.ProvisioningOperation == armresources.ProvisioningOperation("Create") &&
+ *op.Properties.TargetResource.ResourceType == "Microsoft.Resources/resourceGroups" {
+ ownedRGs[*op.Properties.TargetResource.ResourceName] = true
+ }
+}
+```
+
+### Tip 3: Tier Evaluation Order and Short-Circuiting
+
+Consider reordering the tiers for performance. The design says Tier 4
+(vetoes) runs first, but Tier 1 (deployment operations) is a SINGLE
+API call that covers ALL RGs at once. Suggested implementation order:
+
+```
+1. Call deployment.Operations() once (Tier 1 data, 1 API call for all RGs)
+2. For each RG:
+ a. Run Tier 1 classification from cached operations
+ b. If classified "owned" → run Tier 4 veto checks (extra-resource, locks)
+ c. If classified "external" → skip (no Tier 4 needed)
+ d. If Tier 1 unavailable → run Tier 2 (tags), then Tier 4 if "owned"
+ e. If still unknown → Tier 3 (prompt or skip)
+```
+
+This way, Tier 4's per-RG API calls (resource enumeration, locks) only
+run for RGs that are candidates for deletion — typically 1-3 RGs, not all
+referenced RGs.
+
+### Tip 4: Parallelize Tier 4 Per-RG Checks
+
+```go
+type classifyResult struct {
+ name string
+ classification ResourceGroupClassification
+ tier int
+ reason string
+ err error
+}
+
+results := make(chan classifyResult, len(rgNames))
+sem := make(chan struct{}, 5) // limit to 5 concurrent ARM calls
+
+for _, rg := range rgNames {
+ go func(rgName string) {
+ sem <- struct{}{}
+ defer func() { <-sem }()
+ // run Tier 4 checks for this RG
+ results <- classifyResult{...}
+ }(rg)
+}
+
+classified := make([]ClassifiedResourceGroup, 0, len(rgNames))
+for range rgNames {
+ r := <-results
+ classified = append(classified, ...)
+}
+```
+
+### Tip 5: Handle Both Deployment States (Succeeded vs Failed)
+
+`resourceGroupsFromDeployment()` has two branches. Your classifier
+receives the RG names from this function regardless of which branch
+produced them. For FAILED deployments:
+- `deployment.Operations()` may be partially populated — use it
+- Some RGs in the candidate set may never have been created — Tier 1
+ will show no Create op (correct: `unknown`/`external`)
+- `DeleteResourceGroup()` for a non-existent RG returns 404 — handle
+ this as success (already gone), not as a fatal error
+
+### Tip 6: Testing Strategy
+
+Use the existing `mocks.NewMockContext` and `mockexec.MockCommandRunner`
+patterns. The classifier is highly testable because each tier is a
+discrete function:
+
+```
+Test matrix:
+- Tier 1: Create op found / Read op found / No ops / API error / nil fields
+- Tier 2: Both tags / one tag / no tags / wrong env name / API error
+- Tier 4: No extra resources / extra with azd tag / extra without tag /
+ lock present / lock check 403
+- Tier 3: Interactive approve / deny / --force mode
+- Cross-tier: Tier 4 veto overrides Tier 1 owned / Tier 1 unavailable falls
+ to Tier 2 / All tiers degrade gracefully
+- Layered: Scenario 1/2/3 from architecture doc
+- Failed deployments: fail-before-RG-create / fail-after / canceled
+- Partial deletion: RG1 succeeds, RG2 fails, void NOT called
+```
+
+### Tip 7: `--force` Must NOT Short-Circuit Classification
+
+The existing pattern `if options.Force() { return nil }` in
+`promptDeletion()` MUST be changed. Classification runs unconditionally.
+`--force` only affects:
+1. Skipping the interactive confirmation for owned RGs
+2. Converting Tier 3 unknown → external (never deleted)
+
+```go
+// WRONG (existing pattern):
+if options.Force() { return nil }
+
+// RIGHT (new pattern):
+classified := classifier.Classify(ctx, rgNames, deployment)
+// classification always runs, regardless of --force
+if !options.Force() {
+ // show classified preview and prompt for owned RGs
+ // prompt per-RG for unknown RGs (soft Tier 4 veto)
+}
+// delete only owned (+ user-approved in interactive mode)
+```
+
+### Tip 8: Void State Only After Full Success
+
+```go
+// Delete all owned RGs, collecting results
+var deleteErrors []error
+for _, rg := range ownedRGs {
+ if err := resourceService.DeleteResourceGroup(ctx, subId, rg.Name); err != nil {
+ deleteErrors = append(deleteErrors, fmt.Errorf("deleting %s: %w", rg.Name, err))
+ }
+}
+
+// Only void if ALL succeeded
+if len(deleteErrors) == 0 {
+ if err := voidSubscriptionDeploymentState(ctx, subId, deploymentName, opts); err != nil {
+ return fmt.Errorf("voiding deployment state: %w", err)
+ }
+} else {
+ return errors.Join(deleteErrors...)
+}
+```
+
+### Tip 9: Tag Access Requires Code Change in ResourceService
+
+The existing `ResourceService.ListResourceGroup()` (resource_service.go)
+strips tags from the response. The classifier needs RG tags for Tier 2 and
+Tier 4 (azd-env-name on extra resources). Either:
+- Add a `GetResourceGroupWithTags()` method that preserves the ARM response's
+ `Tags` field
+- Or modify `Resource` struct to include `Tags map[string]*string`
+
+Similarly, `ListResourceGroupResources()` returns `ResourceExtended` which
+includes tags — verify this is sufficient for the Tier 4 extra-resource
+check on individual resources.
+
+### Tip 10: Error Handling for ARM API Degradation
+
+Each Tier's ARM calls can fail independently. Handle per the fail-safe
+principle:
+
+| API Call | 403 | 404 | 429 | 5xx |
+|----------|-----|-----|-----|-----|
+| Operations | Fall to Tier 2 | Fall to Tier 2 | Retry 3x | Retry 3x |
+| RG Locks | Skip lock check | Skip lock check | Retry 3x | Retry 3x |
+| RG Resources | SKIP (veto — cant verify) | SKIP | Retry 3x | Retry 3x |
+| RG Tags | Fall to Tier 3 | Fall to Tier 3 | Retry 3x | Retry 3x |
+
+Never let an API error convert to "owned" — errors always fail safe
+toward skip/unknown.

+contributors and Go language experts. Each reviewer was calibrated against
+their actual commit history, focus areas, and review style.
+
+### Contributor Review Panel
+
+#### Victor Vazquez (@vhvb1989)
+
+**Verdict**: REQUEST CHANGES — Telemetry design is non-negotiable for a safety
+feature.
+
+**Findings**:
+
+1. **[CR-001 HIGH] No telemetry design for classification outcomes** —
+ The 4-tier pipeline makes critical delete-vs-skip decisions, but zero tracing
+ spans or telemetry events are specified. When a user reports "azd down skipped
+ my RG and I don't know why", there's nothing to inspect. Every classification
+ result (`owned`/`external`/`unknown`/`vetoed`) MUST emit a span with attributes:
+ `rg.name`, `tier.decided`, `classification`, `reason`.
+
+ **Resolution**: Added **Tip 11** — Telemetry Instrumentation requirement.
+ Each classification decision emits a structured trace span. The overall
+ `Destroy()` operation emits a summary span with owned/skipped/vetoed counts.
+
+2. **[CR-002 HIGH] Error classification for new ARM calls is unspecified** —
+ `ManagementLockClient` is never used in this codebase. What `ResponseError`
+ codes does it return beyond 403? Sentinel errors need defining, following the
+ `ErrDeploymentNotFound` pattern at `standard_deployments.go:293-297`.
+
+ **Resolution**: Added to **Tip 10** — define `ErrLockCheckFailed` sentinel
+ with structured wrapping. Lock check errors fall through (skip check), never
+ escalate to hard failure.
+
+3. **[CR-003 MEDIUM] Tier 1 `provisioningOperation` string comparison needs nil
+ safety** — ARM SDK returns `*string`. Raw dereference panics on nil. Use a
+ helper `operationIs(op, "Create") bool` or Go 1.26's nil-safe patterns.
+
+ **Resolution**: Already covered in **Tip 2** (ARM SDK Nil Guard Pattern).
+ Added: extract `operationIs()` helper to centralize nil-safe checks.
+
+4. **[CR-004 LOW] Extra-resource check calls ListResourceGroupResources for every
+ candidate RG** — Each is a paged enumeration. For N candidate RGs, that's N
+ paging calls before classification. Consider cheaper signals or batching.
+
+ **Resolution**: Addressed by **Tip 3** ordering — Tier 4 only runs on RGs
+ already classified "owned" by Tier 1, dramatically reducing API calls.
+
+#### Wei Lim (@nicklhw)
+
+**Verdict**: APPROVE WITH COMMENTS — Design is sound but needs an API call
+budget table.
+
+**Findings**:
+
+5. **[CR-005 HIGH] API call explosion in classification pipeline** — Worst case
+ per RG: lock check (1 call) + extra-resource check (1+ paged) + Tier 1 ops
+ (1+ paged) + Tier 2 tags (1 GET). For 5 RGs, that's 15+ calls vs zero today.
+ Must specify parallelization strategy and timeout budget.
+
+ **Resolution**: Added **Tip 12** — API Call Budget with worked examples.
+ Tier 1 is ONE call for ALL RGs (shared operations list). Tier 4 only runs
+ on "owned" candidates. Parallel Tier 4 with semaphore. Expected: 3-5 calls
+ for typical deployment vs 15+ worst case.
+
+6. **[CR-006 HIGH] Tier 1 is one API call with client-side filtering, not N
+ calls** — `ListSubscriptionDeploymentOperations` returns ALL operations for
+ the deployment. The design reads as though each RG triggers a separate call.
+
+ **Resolution**: Clarified in architecture — Tier 1 section now explicitly
+ states: "Single API call, client-side filter by resource type and operation
+ type." Already reflected in **Tip 3** ordering.
+
+7. **[CR-007 MEDIUM] Paging completeness for lock enumeration** — Lock-list must
+ handle `pager.More()/NextPage()` pattern. Reading only page 1 misses locks on
+ RGs with many locked resources.
+
+ **Resolution**: Added note to **Tip 2** — all new ARM list calls must use
+ the standard pager exhaustion pattern per `standard_deployments.go:291-300`.
+
+8. **[CR-008 MEDIUM] Progress display during classification** — Currently shows
+ spinner "Discovering resources..." with no progress updates during the
+ (potentially long) classification phase. Users see a stalled spinner.
+
+ **Resolution**: Added **Tip 13** — Progress UX. Classification phase shows
+ per-RG progress: "Classifying rg-app... (owned)", "Classifying rg-db...
+ (external — skipping)". Uses existing `async.Progress[T]` pattern.
+
+9. **[CR-009 LOW] Operation list caching opportunity** — Tier 1 fetches the full
+ operations list. Same data is used later for progress display. Cache to avoid
+ redundant fetch.
+
+ **Resolution**: Noted in **Tip 3** — operations list should be cached and
+ passed to both classifier and progress display.
+
+#### Wallace Breza (@wbreza)
+
+**Verdict**: REQUEST CHANGES — Need stacks graduation migration plan and
+`DeploymentService` interface resolution.
+
+**Findings**:
+
+10. **[CR-010 HIGH] Classifier creates a parallel ownership model that complicates
+ stacks graduation** — When deployment stacks GA, they provide native ARM-level
+ resource ownership. The 4-tier classifier builds client-side ownership using
+ ops+tags+heuristics. These will diverge. Will the classifier persist "because
+ some users haven't migrated"?
+
+ **Resolution**: Added **Section: Stacks Graduation Migration Plan** (below).
+ Explicit sunset: when stacks reach GA, classifier is deprecated. Migration
+ path: `azd config set alpha.deploymentStacks on` → behavior equivalent.
+ Classifier code remains but emits deprecation warning after stacks GA.
+
+11. **[CR-011 HIGH] `DeploymentService` interface asymmetry after MR-002** —
+ `DeleteSubscriptionDeployment` becomes a thin void wrapper, but
+ `DeleteResourceGroupDeployment` still directly deletes. One `Delete*` voids
+ and the other deletes — confusing for every future reader.
+
+ **Resolution**: Rename `DeleteSubscriptionDeployment` to
+ `VoidSubscriptionDeploymentState` to reflect its new semantics. Add a
+ matching `VoidResourceGroupDeploymentState` for the RG-scoped path.
+ Both deletion loops live in `BicepProvider.Destroy()`. Updated in
+ **Tip 1** (Restructure Deletion Flow).
+
+12. **[CR-012 MEDIUM] Extension framework interaction** — Extensions via gRPC
+ can hook into lifecycle events. If the classifier runs inside
+ `BicepProvider.Destroy()`, extensions that implement custom destroy logic
+ won't have access to classification results.
+
+ **Resolution**: Classification results should be included in the
+ `DestroyOptions` context. Extensions creating resources in shared RGs can
+ annotate them with `azd-env-name` tags to avoid false vetoes. Documented
+ as a known consideration — full extension API integration deferred to
+ follow-up.
+
+13. **[CR-013 MEDIUM] Per-RG prompt breaks existing UX contract** — Today there's
+ ONE confirmation prompt. Adding per-RG prompts for "unknown" classification
+ means N additional prompts — UX regression.
+
+ **Resolution**: Added **Tip 14** — Batch UX. Unknown RGs are batched into a
+ single multi-select prompt: "The following resource groups have unknown
+ ownership: [list]. Select which to delete: [ ] rg-a [ ] rg-b [none]".
+ Default: none selected.
+
+14. **[CR-014 LOW] Environment caching interaction** — Env caching (#6076) may
+ serve stale `azd-env-name` values. If user changed env name, Tier 2 tag
+ matching produces wrong results.
+
+ **Resolution**: Tier 2 compares live ARM tags against the current env name
+ from `environment.GetEnvName()`, not cached values. Documented as a note
+ in Tier 2 description.
+
+#### Matt Ellis (@ellismg)
+
+**Verdict**: REQUEST CHANGES — Minimize exported types. Prove each one earns
+its keep.
+
+**Findings**:
+
+15. **[CR-015 HIGH] Over-abstraction — "4-Tier Pipeline" introduces too many
+ types** — Classifier struct, result type, classification enum, tier
+ interfaces? Can this be a single function
+ `classifyResourceGroups(ctx, deployment, rgNames) (owned, skipped []string, err error)`
+ with tiers as internal implementation?
+
+ **Resolution**: Accepted. The classifier SHOULD be a function, not a type.
+ The tiers are implementation details. Exported API is:
+
+ ```go
+ // Package-level function, not a struct method
+ func ClassifyResourceGroups(
+ ctx context.Context,
+ deployment Deployment,
+ rgNames []string,
+ opts ClassifyOptions,
+ ) (ClassifyResult, error)
+
+ type ClassifyResult struct {
+ Owned []string
+ Skipped []ClassifiedSkip // name + reason for UX
+ }
+
+ type ClassifiedSkip struct {
+ Name string
+ Reason string // "external (Tier 1: deployment ops)", etc.
+ }
+
+ type ClassifyOptions struct {
+ Interactive bool
+ EnvName string
+ Prompter func(rgName, reason string) (bool, error)
+ }
+ ```
+
+ Tiers are unexported helper functions. No tier interfaces. Updated in
+ **Tip 15** — Minimal Type Surface.
+
+16. **[CR-016 HIGH] Pointer field nil safety requires an extraction helper** —
+ ARM SDK's `DeploymentOperation` fields are all pointers. Demand a helper
+ `operationIs(op, "Create") bool` rather than inline nil checks everywhere.
+
+ **Resolution**: Already covered by CR-003 and **Tip 2**. Consolidated:
+ `operationIs()` helper is mandatory, not optional.
+
+17. **[CR-017 MEDIUM] New `ManagementLockClient` dependency widens import graph**
+ — Check whether lock types are in the existing `armresources` package or a
+ new module. Don't import a whole new ARM module for a best-effort check.
+
+ **Resolution**: `ManagementLockClient` is in the existing
+ `github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/resources/armlocks`
+ package — this IS a new import. Justified because lock detection is critical
+ for safety. Documented as an accepted import addition.
+
+18. **[CR-018 MEDIUM] Classification enum should be a Go type, not raw strings**
+ — Define `type Classification string` with constants. Raw string comparisons
+ are fragile.
+
+ **Resolution**: Already in the design. Per CR-015, the exported API uses
+ `ClassifiedSkip.Reason` (string for human display) while internal logic
+ uses typed constants: `const classOwned classification = "owned"` (unexported).
+
+19. **[CR-019 LOW] `bicep_provider.go` is already 1300+ lines — consider
+ `bicep_destroy.go`** — After MR-002 moves the deletion loop + classification
+ into `Destroy()`, the file grows further.
+
+ **Resolution**: Accepted. Extract destroy-related methods into
+ `bicep_destroy.go` in the same package. Updated in **Tip 1**.
+
+#### hemarina
+
+**Verdict**: REQUEST CHANGES — Failed-deployment path and RG-scoped adaptation
+are underspecified.
+
+**Findings**:
+
+20. **[CR-020 HIGH] `resourceGroupsFromDeployment` failed-deployment fallback
+ bypasses classification** — Lines 383-397: when `ProvisioningState !=
+ Succeeded`, RGs are extracted from `Dependencies` which conflates owned and
+ external. If the last deployment failed, Tier 1 operations may be incomplete.
+
+ **Resolution**: Added **Tip 16** — Failed Deployment Handling. For failed
+ deployments:
+ - Tier 1 still runs (operations are available even for failed deployments)
+ - If operations are incomplete, classification falls to Tier 2/3
+ - The dependency-extracted RG list is treated as "candidates" only — every
+ candidate still goes through the full classification pipeline
+ - Never shortcut classification based on provisioning state
+
+21. **[CR-021 HIGH] Partial deletion + void timing interaction** — 3 RGs
+ classified "owned". RG1 deletes ok. RG2 fails (lock added after
+ classification). RG3 never attempted. Next retry: `resourceGroupsFromDeployment`
+ still references RG1 (deleted). Classifier tries to check a deleted RG.
+ Lock check → 404, tag check → 404...
+
+ **Resolution**: Added to **Tip 10** error handling: 404 on RG during
+ classification → classify as "already deleted" → skip (not an error).
+ Added `ClassificationAlreadyDeleted` internal status. No void on partial
+ failure is already specified (MR-008).
+
+22. **[CR-022 MEDIUM] RG-scoped deployment has fundamentally different structure**
+ — `DeleteResourceGroupDeployment` takes `resourceGroupName` — it already
+ knows the RG. Classification there is about resources *inside* the RG, not
+ RG ownership. Tier 1 is irrelevant, Tier 2 is on the known RG, and only
+ Tier 4 extra-resource check is meaningful.
+
+ **Resolution**: Added **Tip 17** — RG-Scoped Adaptation. For RG-scoped:
+ - Skip Tier 1 (N/A — RG identity known)
+ - Run Tier 2 tag check on the RG itself
+ - Run Tier 4 extra-resource check (are all resources in this RG azd-owned?)
+ - Run Tier 3 prompt if uncertain
+ - The classifier function accepts a `scope` parameter to select the
+ appropriate tier subset
+
+23. **[CR-023 MEDIUM] "Read → external" heuristic needs nuance** — `Read` in
+ deployment operations can mean "template declared RG as `existing`" OR
+ "template referenced a resource that happens to be in this RG". These are
+ different — first is clearly external, second might be a nested dependency
+ in an owned RG.
+
+ **Resolution**: Clarified Tier 1 logic: `Read` on
+ `Microsoft.Resources/resourceGroups` → external. `Read` on other resource
+ types in an RG → does NOT classify the parent RG as external. Only
+ RG-level operations drive RG classification.
+
+24. **[CR-024 LOW] Cross-layer Tier 4 misses untagged sibling-layer RGs** —
+ Older azd versions created RGs without `azd-env-name` tags. Name-convention
+ fallback (`rg-{env}` / `{env}-rg`) needed.
+
+ **Resolution**: Added to Tier 4 cross-layer section: if RG lacks
+ `azd-env-name` tag, also check name convention patterns from
+ `azure_resource_manager.go:272-297` before classifying as foreign.
+
+### Go Expert Review Panel
+
+#### Standard Library Purist
+
+**Verdict**: APPROVE WITH COMMENTS
+
+**Findings**:
+
+25. **[GO-001 HIGH] Interface bloat risk** — If `ResourceGroupOwnershipClassifier`
+ mirrors the 110+ line `DeploymentService` interface, it's too big. Prefer
+ function injection or tiny interfaces.
+
+ **Resolution**: Resolved by CR-015. The classifier is a function, not a
+ type. Dependencies are passed via `ClassifyOptions` or as function
+ parameters. No new interface needed.
+
+26. **[GO-002 MEDIUM] Stringly-typed tier logic** — `"Create"` / resource type
+ checks need centralized, typed helpers.
+
+ **Resolution**: Covered by CR-003/CR-016. The `operationIs()` helper
+ centralizes string comparisons with `strings.EqualFold` for case safety.
+
+27. **[GO-003 MEDIUM] Error context quality** — Every tier error must be wrapped
+ with RG/deployment/tier context.
+
+ **Resolution**: Added to **Tip 10**: all errors wrapped with
+ `fmt.Errorf("classify rg=%s tier=%d: %w", rgName, tier, err)`.
+
+#### Production Systems Engineer
+
+**Verdict**: REQUEST CHANGES
+
+**Findings**:
+
+28. **[GO-004 HIGH] Missing end-to-end timeout budget** — Per-call retries without
+ a global deadline can hang `azd down` indefinitely.
+
+ **Resolution**: Added **Tip 12** — classification phase gets a global
+ `context.WithTimeout(ctx, 2*time.Minute)`. Individual ARM calls inherit
+ this context. If timeout expires, all pending classifications fail safe to
+ "unknown" → Tier 3 prompt or CI skip.
+
+29. **[GO-005 HIGH] Retry amplification risk** — Parallel goroutines × SDK
+ retries × custom retries = thundering herd potential.
+
+ **Resolution**: Clarified in **Tip 12**: do NOT add custom retry loops.
+ Rely on Azure SDK's built-in retry policy (`azcore.ClientOptions.Retry`).
+ The semaphore limits concurrency to 5 parallel Tier 4 checks. No custom
+ retry on top of SDK retry.
+
+30. **[GO-006 MEDIUM] Insufficient operator observability** — Need structured
+ per-RG decision logs with tier outcomes and fallback path.
+
+ **Resolution**: Covered by CR-001 (telemetry) + **Tip 11**. Structured
+ logging at DEBUG level + trace spans for each classification decision.
+
+31. **[GO-007 MEDIUM] Incident escape hatch** — No "safe mode" for ARM incidents.
+
+ **Resolution**: Existing mechanisms suffice: `--force` skips prompts for
+ owned only (safe by design). If ARM is degraded, classification falls to
+ Tier 3 (prompt) or CI refuses to delete unknowns. No additional escape
+ hatch needed — the fail-safe design IS the escape hatch.
+
+#### Azure SDK Specialist
+
+**Verdict**: REQUEST CHANGES
+
+**Findings**:
+
+32. **[GO-008 HIGH] Tier 1 signal may be brittle** —
+ `ProvisioningOperation=="Create"` for RG ownership is not universally stable.
+ Case sensitivity matters. Validate against real payloads.
+
+ **Resolution**: Use `strings.EqualFold` for all ARM enum comparisons.
+ Added to **Tip 2**: the `operationIs()` helper MUST use case-insensitive
+ comparison. Additionally, validate the expected value against real ARM
+ responses during testing (add integration test with recorded cassette).
+
+33. **[GO-009 HIGH] Locks API specifics — pagination** — Management locks are
+ paged at RG scope. Must handle full pagination before declaring "no lock."
+
+ **Resolution**: Covered by CR-007. Standard pager exhaustion pattern is
+ mandatory for all new ARM list calls.
+
+34. **[GO-010 MEDIUM] Double-retry policy** — Azure SDK already retries 429/5xx.
+ Custom retry wrapper would over-delay and over-load.
+
+ **Resolution**: Covered by GO-005. No custom retry. SDK retry is sufficient.
+ Remove "Retry 3x" from the error handling table — replace with "SDK retry
+ (built-in)" to clarify that no custom retry logic is added.
+
+35. **[GO-011 MEDIUM] `ResourceGroupsClient.Get()` tag behavior** — Verify that
+ `.Tags` is populated by default. Do not rely on `createdTime`.
+
+ **Resolution**: Confirmed — `ResourceGroupsClient.Get()` returns `Tags` by
+ default in `armresources.ResourceGroup`. No extra parameters needed.
+ `createdTime` was already removed from the design (MR-001 removed timestamp
+ veto entirely).

+
+### Additional Tips (11-17)
+
+### Tip 11: Telemetry Instrumentation (CR-001)
+
+Every classification decision MUST emit structured telemetry:
+
+```go
+// In the classify function, after each RG is classified:
+tracing.SetSpanAttributes(ctx,
+ attribute.String("rg.name", rgName),
+ attribute.String("classification", string(result)),
+ attribute.Int("tier.decided", tierNumber),
+ attribute.String("reason", reason),
+)
+
+// Summary span on the overall Destroy() operation:
+tracing.SetSpanAttributes(ctx,
+ attribute.Int("rg.owned.count", len(owned)),
+ attribute.Int("rg.skipped.count", len(skipped)),
+ attribute.Int("rg.vetoed.count", vetoedCount),
+)
+```
+
+At DEBUG log level, emit human-readable lines:
+
+```
+DEBUG classify rg=rg-app tier=1 decision=owned reason="Create operation found"
+DEBUG classify rg=rg-db tier=1 decision=external reason="Read operation only"
+```
+
+This is non-negotiable for a safety-critical feature. Operators must be able
+to trace exactly why any RG was or wasn't deleted.
+
+### Tip 12: API Call Budget and Timeout (CR-005, GO-004, GO-005)
+
+**Global timeout**: Classification phase gets `context.WithTimeout(ctx, 2*time.Minute)`.
+If timeout fires, all pending classifications fail safe to "unknown".
+
+**No custom retry**: Rely on Azure SDK's built-in retry policy only.
+Do NOT wrap ARM calls in custom retry loops — this causes retry amplification
+when combined with SDK retries and parallel goroutines.
+
+**Parallelization**: Tier 4 checks run with a semaphore (buffered channel,
+capacity 5). Tier 1 is a single shared call — no parallelization needed.
+
+**Expected API call counts**:
+
+| Scenario | Tier 1 | Tier 4 (locks) | Tier 4 (resources) | Tier 2 (tags) | Total |
+|----------|--------|----------------|--------------------| --------------|-------|
+| 1 RG, owned | 1 | 1 | 1 | 0 | 3 |
+| 5 RGs, 3 owned 2 external | 1 | 3 | 3 | 0 | 7 |
+| 5 RGs, all unknown (Tier 1 fails) | 1 | 0 | 0 | 5 | 6 |
+| 3 layers × 2 RGs | 3 | ~3 | ~3 | 0 | ~9 |
+
+Note: Tier 4 only runs on "owned" candidates (after Tier 1). External and
+unknown RGs skip Tier 4 entirely.
+
+### Tip 13: Progress UX During Classification (CR-008)
+
+The classification phase can take several seconds. Show per-RG progress:
+
+```
+Classifying resource groups...
+ rg-app: owned (deployment created)
+ rg-db: external (referenced only) — will skip
+ rg-shared: checking...
+```
+
+Use the existing `async.Progress[T]` pattern. The classification progress
+sits between "Discovering resources..." and the deletion confirmation prompt.
+
+### Tip 14: Batch Unknown RG Prompt (CR-013)
+
+Do NOT show N sequential yes/no prompts for unknown RGs. Batch into one
+multi-select:
+
+```
+The following resource groups have unknown ownership (azd couldn't determine
+if it created them). Select which to delete:
+
+ [ ] rg-shared-infra (contains 12 resources, no azd tags)
+ [ ] rg-network (contains 3 resources, partial azd tags)
+
+Default: none selected (safest option)
+> Select: _
+```
+
+In `--force` / CI mode: unknown RGs are NEVER deleted (no prompt shown).
+
+### Tip 15: Minimal Type Surface (CR-015)
+
+Export only what consumers need. The classifier is a function, not a type:
+
+```go
+// Exported — the public API
+func ClassifyResourceGroups(
+ ctx context.Context,
+ ops []armresources.DeploymentOperation,
+ rgNames []string,
+ opts ClassifyOptions,
+) (ClassifyResult, error)
+
+type ClassifyOptions struct {
+ Interactive bool
+ EnvName string
+ Prompter func(rgName, reason string) (bool, error)
+ // ARM clients passed as function-typed fields, not interfaces
+ ListLocks func(ctx context.Context, rg string) ([]Lock, error)
+ ListResources func(ctx context.Context, rg string) ([]Resource, error)
+ GetRGTags func(ctx context.Context, rg string) (map[string]*string, error)
+}
+
+type ClassifyResult struct {
+ Owned []string
+ Skipped []ClassifiedSkip
+}
+
+type ClassifiedSkip struct {
+ Name string
+ Reason string
+}
+```
+
+Unexported helpers implement the tiers:
+
+```go
+func classifyTier1(ops []armresources.DeploymentOperation, rg string) classification { ... }
+func classifyTier2(tags map[string]*string, envName string) classification { ... }
+func checkTier4Locks(ctx context.Context, listLocks lockLister, rg string) (bool, error) { ... }
+func checkTier4ExtraResources(ctx context.Context, listRes resLister, rg, envName string) (bool, error) { ... }
+```
+
+No `ResourceGroupOwnershipClassifier` struct. No tier interfaces. The
+function signature IS the contract.
+
+### Tip 16: Failed Deployment Handling (CR-020)
+
+When `deployment.ProvisioningState != Succeeded`:
+
+1. `resourceGroupsFromDeployment` extracts RGs from `Dependencies` (broader,
+ includes `existing` references) — these are **candidates only**
+2. Classification pipeline runs on ALL candidates (never skip classification
+ because the deployment failed)
+3. Tier 1 operations ARE available for failed deployments — ARM records ops
+ even for partially-completed deployments
+4. If operations list is empty/incomplete, Tier 1 returns "unknown" → falls
+ to Tier 2 tags
+5. Never refuse to run `azd down` because of a failed deployment — the user
+ may be trying to clean up after a failure
+
+```go
+// Candidate extraction doesn't change
+rgNames := resourceGroupsFromDeployment(deployment)
+
+// Classification ALWAYS runs regardless of provisioning state
+result, err := ClassifyResourceGroups(ctx, ops, rgNames, opts)
+```
+
+### Tip 17: RG-Scoped Adaptation (CR-022)
+
+For `DeleteResourceGroupDeployment` (RG-scoped), the pipeline adapts:
+
+| Tier | Subscription-Scoped | RG-Scoped |
+|------|---------------------|-----------|
+| 1 (Operations) | Filter ops for RG Create | **Skip** (RG identity known) |
+| 2 (Tags) | Check both azd tags | Check azd tags on the known RG |
+| 4 (Locks) | Check per candidate | Check on the known RG |
+| 4 (Extra resources) | Check per candidate | **Primary check** — are all resources azd-owned? |
+| 3 (Prompt) | Per-RG for unknowns | Single prompt for the known RG |
+
+The `ClassifyOptions` gains a `Scope` field:
+
+```go
+type ClassifyScope int
+const (
+ ScopeSubscription ClassifyScope = iota
+ ScopeResourceGroup
+)
+```
+
+For RG-scoped, the function receives a single-element `rgNames` slice and
+skips Tier 1. Tier 4 extra-resource check becomes the primary signal.
+
+### Stacks Graduation Migration Plan (CR-010)
+
+**Current state**: Deployment stacks are alpha (`alpha.deploymentStacks`).
+The classifier is the safety net for the default `StandardDeployments` path.
+
+**When stacks reach GA**:
+1. `StandardDeployments` path emits a deprecation notice: "Consider enabling
+ deployment stacks for native resource ownership tracking"
+2. Classifier continues to work for existing users (no forced migration)
+3. After 2 major versions post-stacks-GA: classifier emits a warning
+ that it will be removed in the next major version
+4. Eventual removal: classifier code deleted, `StandardDeployments.Delete*`
+ methods removed, all users on stacks
+
+**Design principle**: The classifier is a **bridge** to stacks GA, not a
+permanent parallel system. It should be simple enough to delete without
+ceremony when the time comes — which is another reason to keep the type
+surface minimal (Tip 15).

- Add empty EnvName guard in Tier 4 (critical: prevents bypass)
- Context-aware semaphore with select on ctx.Done()
- Tier 4 helpers return errors on credential failures (fail-safe)
- Lock pager short-circuits on first CanNotDelete/ReadOnly lock
- Fix integration test mocks: register ARM client options, credential
provider, individual RG GET, and lock endpoint mocks
- Add 10 new classifier unit tests covering edge cases

Subject: [PATCH 06/25] fix: preserve deployment stacks delete path in azd down
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When deployment stacks alpha feature is enabled, use the original
deployment.Delete() path which deletes the stack object (cascading to
managed resources). The new classification pipeline only applies to
standard deployments.
This fixes Test_DeploymentStacks CI failures where the recording proxy
could not find individual RG DELETE calls — stacks use stack DELETE
instead.

Subject: [PATCH 07/25] test: improve coverage for RG safety destroy
orchestration
- Add destroyViaDeploymentDelete tests (0% -> 80%)
- Add deleteRGList partial failure test (65% -> 85%)
- Add operationTargetsRG + tagValue edge case tests (-> 100%)
- Add deployment stacks + credential resolution tests
- 10 new test cases, all passing

From: Jon Gallant <2163001+jongio@users.noreply.github.com>
Date: Thu, 9 Apr 2026 09:39:50 -0700
Subject: [PATCH 08/25] refactor: extract purge helpers, fix data race in test,
add security tests
- Extract collectPurgeItems helper to eliminate 78-line duplication between
stacks and classification paths in Destroy()
- Extract forceDeleteLogAnalyticsIfPurge helper to DRY Log Analytics cleanup
- Fix data race: use atomic.Int32 for callCount in semaphore cancellation test
- Add vetoedSet size hint for map pre-allocation
- Remove stale tombstone comment about removed functions
- Add 2 security tests: Tier4 500 on resource listing, non-azcore network error

Subject: [PATCH 09/25] fix: cancel preserves state, stacks checked before
zero-resources
- Add errUserCancelled sentinel so declining confirmation does not void
deployment state or invalidate env keys (Goldeneye finding)
- Move deployment-stacks check before len(groupedResources)==0 fast-path
so stacks are always deleted even when ARM shows zero resources
- Add UserCancelPreservesDeploymentState regression test
- Add ZeroResourcesStillDeletesStack regression test

Subject: [PATCH 10/25] fix: restore purge error propagation, filter extension
resources, cancel returns error
- forceDeleteLogAnalyticsIfPurge now returns error (restores fatal behavior)
- Tier 4 skips untaggable extension resource types (Microsoft.Authorization/*, etc.)
- User cancellation returns errUserCancelled instead of nil
- Added Type field to ResourceWithTags, 11 new unit tests

Subject: [PATCH 11/25] fix: collect purge targets before RG deletion, remove
invalid $expand=tags, fix semaphore race
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Three issues found in round 2 triple-model code review:
1. CRITICAL: collectPurgeItems was called AFTER RG deletion in both the
deployment-stacks path and classification path. Since DeleteResourceGroup
polls to completion (PollUntilDone), getKeyVaults/getManagedHSMs/etc.
would 404 when querying resources in already-deleted RGs. Fix: split
classifyAndDeleteResourceGroups into classifyResourceGroups (classify +
confirm, no delete) so the caller can collect purge targets while RGs
still exist, then delete, then purge.
2. HIGH: \=tags is not a valid parameter for the ARM
Resources.ListByResourceGroup API (valid values: createdTime,
changedTime, provisioningState). Tags are already included by default
in GenericResourceExpanded. If ARM rejected the invalid expand with 400,
the classifier would treat it as a fail-safe veto on all owned RGs.
Fix: remove the \ parameter.
3. LOW: Tier 4 semaphore select race — Go's non-deterministic select could
choose the semaphore case even when ctx.Done is ready. Fix: add
ctx.Err() re-check after semaphore acquisition.

Subject: [PATCH 12/25] fix: attempt purge even after partial RG deletion
failure
When deleteRGList partially succeeds (e.g., rg-a deleted but rg-b fails),
the soft-deleted resources from rg-a (Key Vaults, Managed HSMs, etc.)
need purging to avoid name collisions on reprovisioning. Previously,
purgeItems was skipped entirely when deleteErr was non-nil, and on retry
those deleted RGs would be classified as 'already deleted' (Tier 2: 404),
losing their purge targets permanently.
Now purgeItems always runs after deletion. Deletion errors are reported
first (primary failure); purge errors for non-deleted RGs are expected
and secondary.

Subject: [PATCH 13/25] test: add partial-delete purge regression test
Verifies that purgeItems runs even after deleteRGList partially fails:
- rg-ok (with kv-ok) deleted successfully, rg-fail returns 409
- Assert kv-ok purge was called despite partial deletion failure
- Assert voidDeploymentState skipped on partial failure
- Document known limitation in code comment (iteration order edge case)
Covers the fix from the previous commit and addresses the test coverage
gap identified in CR Round 4.

Subject: [PATCH 15/25] fix: --force now runs Tier 1 to protect external RGs +
integration tests
- --force no longer bypasses all classification. Tier 1 (zero extra API
calls) still runs to identify external RGs from deployment operations.
External RGs with Read/EvaluateDeploymentOutput operations are protected
even with --force. Unknown RGs are treated as owned (backward compat).
If operations are unavailable, all RGs are deleted (backward compat).
- Added ForceMode to ClassifyOptions with 5 unit tests covering:
external protection, unknown-as-owned, nil ops fallback, callback
skip verification, and EvaluateDeploymentOutput detection.
- Added Tier4LockVetoPreventsDeletion integration test verifying that
a CanNotDelete lock vetoes deletion even for Tier 1 owned RGs.
- Added MixedOwnedExternalOnlyOwnedDeleted integration test verifying
end-to-end: Created=deleted, Read=skipped, unknown=skipped (non-interactive).
- Updated ForceBypassesClassification -> ForceProtectsExternalRGs test
to verify operations ARE fetched and external RGs ARE protected with --force.
- Extended classifyMockCfg with per-RG lock support and per-RG tag mocks.
- Updated architecture.md: Decision 4 rewritten (Tier 1 only, not full
bypass), gap section updated, risk mitigations updated, added mermaid
classification flow diagram.
Addresses review findings #2 and #3 from @wbreza.

+### Decision 4: --force Runs Tier 1 Only (Zero-Cost Safety)
+
+**Pattern**: Minimal-overhead safety even in CI/CD automation
-**Pattern**: Explicit override for CI/CD and automation
+**Why**: `--force` is used in CI/CD pipelines and scripts where operators want
+teardown without prompts. However, deleting resource groups that azd didn't
+create (external RGs referenced via Bicep `existing` keyword) contradicts the
+core safety goal of this feature. Tier 1 classification (parsing deployment
+operations) is free — zero extra API calls — and can identify external RGs
+with high confidence.
-**Why**: `--force` is used in CI/CD pipelines and scripts where operators accept
-full responsibility for teardown. In the new design, `--force` bypasses the
-entire 4-tier classification pipeline and deletes ALL resource groups from
-the deployment, matching the original behavior. Classification only runs in
-interactive mode (without `--force`). In non-interactive mode
-(`--force`, CI/CD), ALL referenced RGs are deleted — the operator is expected
-to manage scope via their Bicep templates.
+**Behavior**: When `--force` is set, only Tier 1 runs. External RGs identified
+by Read or EvaluateDeploymentOutput operations are still protected (skipped).
+Unknown RGs (no matching operation) are treated as owned and deleted. Tiers
+2/3/4 are skipped entirely (no tag lookups, no prompts, no lock checks).
-**Note**: A future enhancement could make `--force` run the free Tier 1 check
-(zero API calls) and still skip external RGs, but this is deferred to avoid
-breaking existing CI/CD workflows that depend on the current behavior.
+**Degradation**: If deployment operations are unavailable (ARM transient error),
+`--force` falls back to deleting all RGs for backward compatibility. This is
+logged as a WARNING.
No `--delete-resource-groups` or similar bulk override flag exists. This is
a deliberate design choice: azd will never delete a resource group it didn't

### ⚠️ Gap: --force Bypasses All Safety (High) — RESOLVED

-**Resolution**: `--force` bypasses the entire 4-tier classification pipeline
-and deletes ALL resource groups from the deployment, preserving original
-`azd down --force` semantics for CI/CD pipelines. Classification only runs
-when `--force` is not set. This matches Decision 4 (see below) and avoids

Subject: [PATCH 18/25] feat: add bicep snapshot as primary RG classification
source
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Implements @vhvb1989's proposal to use bicep snapshot predictedResources
as the primary classification mechanism for resource group ownership.
Snapshot path (when available):
- RG in predictedResources → owned (template creates it)
- RG NOT in predictedResources → external (uses existing keyword)
- Tier 4 (locks/foreign resources) runs as defense-in-depth
Graceful fallback to existing Tier 1-4 pipeline when snapshot is
unavailable (older Bicep CLI, non-bicepparam mode, errors).
Changes:
- Add SnapshotPredictedRGs field to ClassifyOptions
- Add classifyFromSnapshot() with Tier 4 defense-in-depth
- Add getSnapshotPredictedRGs() to BicepProvider for snapshot extraction
- Add 8 unit tests for snapshot classification
- Update architecture.md with snapshot-primary data flow

-This classifier runs the 4-tier evaluation pipeline for each resource group
-discovered in the deployment, producing a verdict that the deletion logic uses
-to decide whether to proceed.
+This classifier supports two classification modes:
+
+1. **Snapshot-primary mode** (when `SnapshotPredictedRGs` is non-nil): Uses
+ `bicep snapshot` → `predictedResources` as a deterministic, offline source.
+ RGs in the predicted set are owned; RGs absent are external. Tier 4
+ (locks/foreign resources) still runs as defense-in-depth.
+
+2. **Tier pipeline mode** (fallback when snapshot unavailable): Runs the full
+ Tier 1→2→3→4 pipeline as described below.
+
+The snapshot approach is strictly better than Tier 1-3 because it reflects the
+template's _current intent_ rather than historical deployment operations. Resources
+declared with the Bicep `existing` keyword are excluded from `predictedResources`
+by design, providing a direct signal of ownership.

Subject: [PATCH 19/25] refactor: extract runTier4Vetoes, fix MQ quality
findings
- Extract ~90-line duplicated Tier 4 goroutine block into shared
runTier4Vetoes() helper, called from both ClassifyResourceGroups
and classifyFromSnapshot (CRITICAL: tier4-dup)
- Remove duplicate snapshotPredictedResult/snapshotPredictedResource
types from bicep_destroy.go, reuse snapshotResult/armTemplateResource
from local_preflight.go (HIGH: snapshot-types-dup)
- Return nil instead of empty DestroyResult on errUserCancelled since
Manager.Destroy discards result on error (HIGH: err-user-cancelled)
- Use cogAccounts range var directly instead of dead _ = assignment
(MEDIUM: dead-cogaccounts)
- Add log.Printf for non-interactive Tier 4 foreign-resource veto
(LOW: veto-no-log)
- Add 2 new tests: snapshot + Tier 4 interactive accept/reject
- Fix idiomatic issues: new(val) in test helpers, slices.ContainsFunc
for isExtensionResourceType
- Update stale Destroy() doc comment to reflect classification behavior
- Add Tags field doc comment on ResourceWithTags

Date: Sat, 11 Apr 2026 10:40:36 -0700
Subject: [PATCH 20/25] test: fill coverage gaps for RG classification and
snapshot prediction
Add tests for getSnapshotPredictedRGs covering all 7 code paths:
- nil compileBicep cache returns nil
- bicepparam mode returns predicted RGs
- non-bicepparam with params generates temp bicepparam file
- non-bicepparam without params returns nil
- snapshot CLI error returns nil gracefully
- JSON parse error returns nil gracefully
- zero RGs in predicted resources returns nil
Add integration test for force + operations fetch failure:
- When deployment.Operations() returns 500 and force=true,
all resource groups are returned as owned (backward compat)
Add tag key case-insensitivity tests (Tier 2 and Tier 4):
- Mixed-case and UPPER-case tag keys match azd-env-name
- Mixed-case tag keys on resources don't trigger false vetoes
- Wrong env value still triggers foreign resource veto

maps.Keys() returns iter.Seq[string] in Go 1.23+, not []string.
Without slices.Collect(), log.Printf prints the function pointer

Subject: [PATCH 23/25] Remove Tiers 1-3 from resource group classifier, keep
snapshot + Tier 4
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Remove the deployment-operations-based classification tiers (Tier 1: Create
ops, Tier 2: provision-param-hash tag, Tier 3: interactive prompt fallback)
from the resource group classifier. Classification now uses the bicep
snapshot as the primary signal, with Tier 4 (locks + foreign resources) as
defense-in-depth for interactive mode.
When snapshot is unavailable:
- ForceMode: all RGs treated as owned (backward compat, zero API calls)
- Interactive: user prompted per RG with snapshot-unavailable warning
- Non-interactive: all RGs skipped (cannot classify without snapshot)
Changes:
- resource_group_classifier.go: Remove classifyTier1/2/3, operations param,
GetResourceGroupTags callback, ExpectedProvisionParamHash field
- resource_group_classifier_test.go: Full rewrite — snapshot-based tests
- bicep_destroy.go: Remove operations fetching, hash derivation,
getResourceGroupTags method
- bicep_destroy_test.go: Update force-mode test to snapshot-based
- bicep_provider.go: Add snapshotPredictedRGsOverride for test injection
- bicep_provider_test.go: Replace operations mocks with snapshot injection

Subject: [PATCH 24/25] docs: update architecture doc and classifier comments
for snapshot-only approach
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
- Rewrite architecture.md to reflect snapshot-primary architecture (1481→324 lines)
- Remove all Tier 1-3 references (deployment operations, tag verification)
- Add clear ForceMode comment explaining with/without snapshot behavior
- Document lock 403 vs resource 403 asymmetry with rationale
- Update PR description to match current implementation
Addresses wbreza re-review findings:
1. Architecture doc --force contradiction → reconciled
2. ForceMode inline comment misleading → rewritten with clear scenarios
3. Lock 403 vs resource 403 asymmetry undocumented → inline comments added

### Design Principle: Fail Safe
-Every tier's failure mode is **"skip deletion"** — never "delete anyway." The
-only path to deleting a resource group requires positive confirmation from at
-least one ownership tier with no vetoes from the always-on safeguards. The
-correct failure direction for a destructive operation is "we didn't delete
-something we could have" not "we deleted something we shouldn't have."

+failure direction for a destructive operation is "we didn't delete something we
+could have" not "we deleted something we shouldn't have."
-### Component Design
+### Classification Approach: Bicep Snapshot
-#### 1. ResourceGroupOwnershipClassifier
+`bicep snapshot` produces a `predictedResources` list containing **only resources
+the template will CREATE** — resources declared with the Bicep `existing` keyword
+are excluded by design. This provides a deterministic, offline, zero-API-call
+answer to the question "does this template own this resource group?"
-**Location**: New type in `cli/azd/pkg/azapi/`
+| Aspect | Snapshot |
+|--------|----------|
+| Data source | Template intent (deterministic, compile-time) |
+| API calls | 0 (offline, local bicep CLI) |
+| Handles template changes | Reflects current template (not stale deploy history) |
+| `existing` handling | Excluded by design |
+| Nested modules | Normalized — all predicted resources flattened |
+| Conditional resources | Evaluated with provided parameter values |
-**Responsibility**: Determines whether azd created a given resource group by
-querying multiple signals and producing a classification verdict.
+### Component Design
-```
-// Actual implementation uses a function-based API:
+#### 1. ClassifyResourceGroups
-// ClassifyResult holds the output of ClassifyResourceGroups.
-type ClassifyResult struct {
- Owned []string // RG names approved for deletion
- Skipped []ClassifiedSkip // RG names skipped with reasons
-}
+**Location**: `cli/azd/pkg/azapi/resource_group_classifier.go`
-type ClassifiedSkip struct {
- Name string // resource group name
- Reason string // human-readable explanation (includes tier info)
-}
+**Responsibility**: Determines whether azd owns each resource group by consulting
+the Bicep snapshot and running defense-in-depth safety checks.
-// ClassifyResourceGroups evaluates each RG through the 4-tier pipeline.
+```go
func ClassifyResourceGroups(
ctx context.Context,
- operations []*armresources.DeploymentOperation,
rgNames []string,
opts ClassifyOptions,
) (*ClassifyResult, error)
```
-This classifier supports two classification modes:
-
-1. **Snapshot-primary mode** (when `SnapshotPredictedRGs` is non-nil): Uses
- `bicep snapshot` → `predictedResources` as a deterministic, offline source.
- RGs in the predicted set are owned; RGs absent are external. Tier 4
- (locks/foreign resources) still runs as defense-in-depth.
-
-2. **Tier pipeline mode** (fallback when snapshot unavailable): Runs the full
- Tier 1→2→3→4 pipeline as described below.
-
-The snapshot approach is strictly better than Tier 1-3 because it reflects the
-template's _current intent_ rather than historical deployment operations. Resources
-declared with the Bicep `existing` keyword are excluded from `predictedResources`
-by design, providing a direct signal of ownership.
-
-#### 2. Enhanced DeleteSubscriptionDeployment
+The classifier operates in two modes:
-**Location**: Modified method in `standard_deployments.go`
+1. **Snapshot available** (`SnapshotPredictedRGs != nil`): RGs in the predicted
+ set are owned; RGs absent are external. Tier 4 (locks + foreign resources)
+ runs on all owned candidates as defense-in-depth.
-**Responsibility**: Replace the current "delete all RGs" loop with a
-classification-aware loop that only deletes RGs classified as `owned`.
+2. **Snapshot unavailable** (`SnapshotPredictedRGs == nil`): Conservative guard:
+ - `--force`: all RGs treated as owned (backward compat, zero API calls)
+ - Interactive: user prompted per-RG ("snapshot unavailable — cannot verify
+ ownership")
+ - Non-interactive: all RGs skipped
-**CRITICAL IMPLEMENTATION NOTE** *(from multi-model review MR-002)*:
-The current `Deployment.Delete()` interface calls
-`DeleteSubscriptionDeployment()`, which **independently re-discovers** all
-RGs via `ListSubscriptionDeploymentResources()` → `resourceGroupsFromDeployment()`
-and deletes them all. The classification result from `BicepProvider.Destroy()`
-would never reach this deletion code. The implementer MUST choose one of:
+#### 2. Restructured Destroy Flow
-- **(Recommended) Option A**: Move the per-RG deletion loop OUT of
- `DeleteSubscriptionDeployment()` into `BicepProvider.Destroy()`, which
- already has the classified list. `DeleteSubscriptionDeployment()` becomes
- a thin wrapper that only calls `voidSubscriptionDeploymentState()`.
- `BicepProvider` calls `DeleteResourceGroup()` directly for each owned RG.
-- **Option B**: Add a `allowedResourceGroups []string` parameter to
- `DeleteSubscriptionDeployment()` (and update `DeploymentService` interface).
-- **Option C**: Add a new `DeleteFilteredSubscriptionDeployment()` method.
+**Location**: `cli/azd/pkg/infra/provisioning/bicep/bicep_destroy.go`
-Option A is cleanest because it keeps all classification logic and deletion
-orchestration in `BicepProvider.Destroy()` — the same place that already
-has the deployment, the resources, and the grouped RGs.
+The deletion loop has been moved out of `DeleteSubscriptionDeployment()` into
+`BicepProvider.Destroy()`, which now orchestrates:
-The current method:
-1. Lists all resources from deployment
-2. Extracts unique RG names
-3. Deletes every RG
-
-The new method (Option A):
-1. `BicepProvider.Destroy()` calls `deployment.Resources()` (existing)
-2. Groups by RG name (existing)
-3. **Classifies each RG** via ResourceGroupOwnershipClassifier
-4. Deletes only owned RGs by calling `resourceService.DeleteResourceGroup()`
- directly
-5. Reports skipped RGs to the progress callback
-6. Calls `voidSubscriptionDeploymentState()` ONLY after all intended
- deletions succeed (see MR-008 partial failure fix)
-
-#### 3. Enhanced Destruction Preview
-
-**Location**: Modified `promptDeletion()` in `bicep_provider.go`
-
-**Responsibility**: Show users which resource groups will be deleted vs. skipped,
-with clear provenance labels.
-
-Current behavior: Shows a flat list of resources and asks "are you sure?"
-
-New behavior: Groups resources by RG, labels each RG with its classification
-(`azd-created` / `pre-existing` / `unknown`), and shows separate counts for
-each category. For `unknown` RGs in interactive mode, prompts per-RG.
+1. `compileBicep()` → template + parameters (existing)
+2. `scopeForTemplate()` → deployment scope (existing)
+3. `completedDeployments()` → find most recent deployment (existing)
+4. `deployment.Resources()` → grouped resources (existing)
+5. **`getSnapshotPredictedRGs()`** → set of RG names from `bicep snapshot`
+6. **`classifyResourceGroups()`** → snapshot classification + Tier 4
+7. Delete only owned RGs, skip external/unknown
+8. Purge soft-deleted resources (Key Vault, etc.) in owned RGs only
+9. `VoidSubscriptionDeploymentState()` only after all deletions succeed

-## Patterns & Decisions
+## Key Decisions
+
+### Decision 1: Bicep Snapshot as Primary Classification Signal
-### Decision 1: Multi-Tier Classification over Single-Signal Ownership
+**Pattern**: Leverage compile-time intent over runtime history
-**Pattern**: Defense in depth / Chain of responsibility
+**Why**: `bicep snapshot` → `predictedResources` provides the single best answer
+to "does this template own this resource group?" It reflects the template's
+*current intent* — resources declared with `existing` are excluded by design.
+Unlike deployment operations (which reflect the *last deploy* and can be stale,
+incomplete, or purged), the snapshot is deterministic, offline, and always
+current.
-**Why**: Every individual ownership signal has a fatal flaw when used alone:
+**How it works**:
+1. `getSnapshotPredictedRGs()` invokes `bicep snapshot` with the template and
+ parameters
+2. Filters `predictedResources` for `type == "Microsoft.Resources/resourceGroups"`
+3. Returns a lowercased set of RG names
+4. `nil` return signals snapshot failure → triggers conservative guard
-| Signal | Fatal Flaw |
-|--------|-----------|
-| ARM deployment operations | Gone if deployment data deleted from Azure |
-| azd tags | User-writable; can be spoofed or manually added |
-| Local state file | Not portable across machines |
-| RG creation timestamp | Approximate; race conditions possible |
-| Resource locks | Opt-in; most users don't set them |
+**Edge cases handled**:
+- Conditional RGs (`if (condition)`) — evaluated with provided parameters
+- Nested modules — snapshot normalizes to a flat list
+- ARM expression names (`rg-${env}`) — resolved to concrete values
+- Case-insensitive comparison via `strings.EqualFold` / lowercased set
-By layering signals, the system tolerates any single signal being unavailable
-or compromised. The key insight is that each tier's failure mode is "skip"
-(safe) not "delete" (unsafe).
+### Decision 2: `--force` Uses Snapshot (Deterministic, Zero API Calls)
-**Evaluation order**: Tier 1 (highest confidence, zero API calls) through Tier 3
-(lowest confidence) run in sequence, stopping at the first tier that produces a
-definitive answer. Tier 4 (always-on vetoes) then runs on ALL deletion candidates
-to apply lock and foreign-resource checks regardless of which tier classified them.
+**Pattern**: Minimal-overhead safety even in CI/CD automation
-### Decision 2: Deployment Operations as Primary Signal (Tier 1)
+**Why**: `--force` is used in CI/CD pipelines where operators want teardown
+without prompts. With snapshot available, classification is deterministic and
+free — no extra API calls. External RGs identified by the snapshot are still
+protected (skipped).
-**Pattern**: Leverage existing infrastructure
+**Behavior**:
+- **With snapshot**: Snapshot classifies RGs. Tier 4 is skipped (zero API calls,
+ consistent with `--force` contract of no interactive checks).
+- **Without snapshot**: All RGs treated as owned (backward compat). This is the
+ only path where an external RG could be deleted — it requires *both* snapshot
+ failure *and* explicit `--force`.
-**Why**: The `Deployment.Operations()` method already exists in `scope.go:66`
-and calls `ListSubscriptionDeploymentOperations()`. ARM deployment operations
-include a `provisioningOperation` field with values including `Create`, `Read`,
-`EvaluateDeploymentOutput`, etc. Resources referenced via Bicep `existing`
-keyword produce `Read` or `EvaluateDeploymentOutput` operations — never
-`Create`. This is the single highest-confidence signal available.
+### Decision 3: Tier 4 Defense-in-Depth (Locks + Foreign Resources)
-**How it works**:
-1. Call `deployment.Operations(ctx)` to get all deployment operations
-2. Build a set of resource group names where an operation exists with:
- - `provisioningOperation == "Create"`
- - `targetResource.resourceType == "Microsoft.Resources/resourceGroups"`
-3. Any RG in this set is classified as `owned`
-4. Any RG with an explicit `Read` or `EvaluateDeploymentOutput` operation
- (but no `Create`) is classified as `external` — this is the high-confidence
- signal that the RG was referenced via Bicep `existing`
-5. Any RG with NO operations at all is classified as `unknown` — NOT
- `external`. This handles: (a) nested Bicep module deployments where
- top-level operations don't flatten RG creates (see MR-004), (b)
- partially purged operation history. `unknown` falls through to Tier 2.
-
-**IMPORTANT** *(from multi-model review MR-004)*: ARM does NOT flatten
-nested deployment operations. If an RG is created inside a Bicep module
-(not at the top level of `main.bicep`), the top-level operations will
-show the module as `Microsoft.Resources/deployments` with no direct
-`Create` for the RG. The implementer should either:
-- Recursively walk nested deployment operations (check for
- `TargetResource.ResourceType == "Microsoft.Resources/deployments"`
- and query that sub-deployment's operations)
-- Or classify as `unknown` (not `external`) and let Tier 2 handle it
-
-Standard azd templates declare RGs at top level, so this primarily affects
-user-customized templates. The `unknown` classification is the safe default.
-
-**When it fails**: If deployment history has been purged from Azure (ARM retains
-up to 800 deployments per scope). In this case, fall through to Tier 2.
-
-### Decision 3: Dual-Tag Verification as Fallback (Tier 2)
-
-**Pattern**: Multi-factor verification
-
-**Why**: azd already applies `azd-env-name` tags during provisioning. By
-checking for BOTH `azd-env-name` AND `azd-provision-param-hash` tags, we
-reduce false positives — it is unlikely (though not impossible) that a user
-manually adds both tags with correct values.
-
-**Important**: Tags alone are never sufficient for deletion — this tier only
-activates when Tier 1 is unavailable (deployment operations API returns error
-or empty). Tags are a necessary-but-not-sufficient signal, strengthened by
-requiring two matching tags rather than one.
-
-### Decision 4: --force Runs Tier 1 Only (Zero-Cost Safety)
+**Pattern**: Defense in depth / Fail safe
-**Pattern**: Minimal-overhead safety even in CI/CD automation
+**Why**: Even when the snapshot says "owned," a management lock or foreign
+resources should prevent deletion. Tier 4 catches edge cases the snapshot cannot:
+user-added locks, resources deployed outside azd into an azd-owned RG, etc.
-**Why**: `--force` is used in CI/CD pipelines and scripts where operators want
-teardown without prompts. However, deleting resource groups that azd didn't
-create (external RGs referenced via Bicep `existing` keyword) contradicts the
-core safety goal of this feature. Tier 1 classification (parsing deployment
-operations) is free — zero extra API calls — and can identify external RGs
-with high confidence.
-
-**Behavior**: When `--force` is set, only Tier 1 runs. External RGs identified
-by Read or EvaluateDeploymentOutput operations are still protected (skipped).
-Unknown RGs (no matching operation) are treated as owned and deleted. Tiers
-2/3/4 are skipped entirely (no tag lookups, no prompts, no lock checks).
-
-**Degradation**: If deployment operations are unavailable (ARM transient error),
-`--force` falls back to deleting all RGs for backward compatibility. This is
-logged as a WARNING.
-
-No `--delete-resource-groups` or similar bulk override flag exists. This is
-a deliberate design choice: azd will never delete a resource group it didn't
-create without per-RG human consent.
-
-### Decision 5: Always-On Safeguards as Veto Layer (Tier 4)
-
-**Pattern**: Circuit breaker / Invariant checks
-
-**Why**: Certain conditions should ALWAYS prevent deletion regardless of what
-ownership signals say. These are hard vetoes that override all other tiers:
-
-1. **Resource locks** *(best-effort)*: If an RG has a `CanNotDelete` or `ReadOnly`
- lock, it was explicitly protected by someone. Attempting to delete it will
- fail anyway — better to skip it proactively. **Important**: The lock check
- requires `Microsoft.Authorization/locks/read` permission which azd does not
- currently require. Per the "no new permissions" constraint, this check is
- **best-effort**: if the API returns 403, skip the lock check sub-tier
- entirely (do NOT veto) and log a warning. Alternatively, the implementer
- may omit this check and let ARM's own lock enforcement produce a clear
- error at `DeleteResourceGroup` time.
-
-2. **Extra resources**: If an RG contains resources that are NOT in the
- deployment's resource list AND do not have an `azd-env-name` tag matching
- the current environment, it likely contains resources from other
- deployments or manual provisioning. Deleting the RG would destroy those
- resources as collateral damage. Resources from sibling layers (which share
- the same `azd-env-name` tag) are NOT counted as extra — this enables
- correct behavior in layered provisioning scenarios (see "Layered
- Provisioning Support" section).
-
-3. **~~Timestamp heuristic~~** *(REMOVED — see Multi-Model Review MR-001)*:
- The original design proposed vetoing when `RG.createdTime < deployment.Timestamp`.
- Multi-model review (Opus, Codex, Goldeneye — all 3 independently) identified
- this as critically flawed: on any re-deployment, the RG was created during the
- *first* `azd up` while the deployment timestamp reflects the *latest* `azd up`,
- so the comparison is always true for re-provisioned environments. Additionally,
- ARM SDK does not expose `createdTime` without raw REST `$expand=createdTime`.
- **This sub-tier is removed entirely.** Tiers 1 and 2 plus lock/extra-resource
- checks provide sufficient safety without this fragile heuristic.
+**Lock check (best-effort)**:
+- `CanNotDelete` or `ReadOnly` lock → hard veto (skip deletion)
+- 403 → no veto (best-effort: locks are additive protection; inability to read
+ them does not imply the RG is unsafe to delete)
+- 404 → no veto (RG already deleted)
+
+**Foreign resource check (strict)**:
+- Resources without matching `azd-env-name` tag → prompt if interactive, hard
+ veto otherwise
+- 403 → hard veto (cannot enumerate resources = cannot verify safety; unlike
+ lock 403 where inability to read is benign, resource 403 means we lack
+ visibility into what we'd delete)
+- Extension resource types (roleAssignments, diagnosticSettings, resource links)
+ → skipped (these commonly lack tags and are created by azd scaffold templates)
+
+**Errors → veto**: Any unexpected error in Tier 4 is treated as a veto
+(fail-safe). We log the error and skip deletion rather than risk destroying
+unknown resources.
+
+### Decision 4: Skip Classification When Deployment Stacks Active
+
+Deployment stacks natively track managed vs unmanaged resources via ARM
+Deployment Stacks. When `FeatureDeploymentStacks` is enabled, the snapshot
+classification pipeline is bypassed entirely — ARM handles it correctly already.
+
+### Decision 5: VoidState Only After Full Success
+
+`VoidSubscriptionDeploymentState()` clears the deployment from ARM, destroying
+the evidence needed for future classification. This MUST only happen after all
+intended deletions succeed. On partial failure, the deployment state is preserved
+so a subsequent `azd down` can retry.
## Layered Provisioning Support
@@ -451,1453 +307,126 @@ ownership signals say. These are hard vetoes that override all other tiers:
azd supports **layered provisioning** where `azure.yaml` defines multiple
infrastructure layers under `infra.layers[]`. Each layer is a separate Bicep
-(or Terraform) module with its own ARM deployment. During `azd down`, layers
-are processed in **reverse order** — the last layer provisioned is the first
-layer destroyed (`slices.Reverse(layers)` in `down.go:134`).
+module with its own ARM deployment. During `azd down`, layers are processed in
+**reverse order** — the last layer provisioned is the first layer destroyed.
-Each layer gets:
-- Its own deployment name: `{envName}-{layerName}`
-- Its own ARM deployment with tags: `azd-env-name`, `azd-layer-name`,
- `azd-provision-param-hash`
-- Its own independent `provisionManager.Initialize()` + `Destroy()` cycle
+Each layer gets its own deployment name (`{envName}-{layerName}`), its own ARM
+deployment with tags, and its own independent `Destroy()` cycle.
### Cross-Layer Resource Group Scenarios
The classification pipeline runs per-layer (each layer processes independently).
-The reverse ordering creates important interactions:
+The snapshot for each layer reflects that layer's template.
**Scenario 1: Layer 1 creates RG, Layer 2 references it via `existing`**
Processing order: Layer 2 first, then Layer 1.
-1. Layer 2: Tier 1 checks deployment operations → RG has `Read` operation
- (not `Create`) → classified as `external` → **SKIP**
-2. Layer 1: Tier 1 checks deployment operations → RG has `Create` operation
- → classified as `owned` → **DELETE**
+1. Layer 2 snapshot: RG not in `predictedResources` → external → **SKIP**
+2. Layer 1 snapshot: RG in `predictedResources` → owned → **DELETE**
-Result: Correct. The creating layer deletes the RG after the referencing
-layer has been processed.
+Result: Correct. The creating layer deletes the RG after the referencing layer.
**Scenario 2: Both layers reference a pre-existing RG**
-1. Layer 2: classified as `external` → SKIP
-2. Layer 1: classified as `external` → SKIP
+1. Layer 2: not in snapshot → external → SKIP
+2. Layer 1: not in snapshot → external → SKIP
Result: Correct. Pre-existing RG is preserved.
**Scenario 3: Layer 1 creates RG, Layer 2 deploys resources into it**
-This is the complex case. Layer 2 processes first and skips the RG (correct).
-When Layer 1 processes, the RG contains resources from both layers. Layer 2's
-resources are still present because the RG was not deleted.
-
-Without cross-layer awareness, Tier 4's extra-resource check would find
-Layer 2's resources and veto deletion — even though Layer 1 legitimately
-created the RG.
+Layer 2 processes first and skips the RG (not in Layer 2's snapshot). When
+Layer 1 processes, the RG contains resources from both layers. Tier 4's
+foreign-resource check could find Layer 2's resources.
-**Solution: azd-env-name-aware extra-resource check**
+**Solution: `azd-env-name`-aware foreign resource check**
-The Tier 4 extra-resource check is refined to distinguish truly foreign
-resources from sibling-layer resources:
+Tier 4's extra-resource check distinguishes truly foreign resources from
+sibling-layer resources:
-- Query the RG's actual resources via `ListResourceGroupResources()`
-- For each resource NOT in the current layer's deployment resource list:
- - Check if the resource has an `azd-env-name` tag matching the current
- environment name
- - If YES: the resource belongs to a sibling layer or this deployment —
- it is NOT counted as "extra"
- - If NO: the resource is truly foreign (manually created, from another
- deployment, etc.) — it IS counted as "extra" and triggers the veto
+- For each resource in the RG: check its `azd-env-name` tag
+- If tag matches current environment → sibling-layer resource → not foreign
+- If tag missing or mismatched → truly foreign → triggers veto/prompt
-This approach:
-- Requires no pre-scan pass across layers
-- Works because azd tags resources with `azd-env-name` during provisioning
-- Correctly identifies resources from sibling layers as "safe"
-- Still catches truly foreign resources (those without azd tags or with a
- different environment name)
+This works because azd tags resources with `azd-env-name` during provisioning.
+No pre-scan pass across layers is needed.
-**Scenario 3 with the fix**:
-
-1. Layer 2: Tier 1 → `external` → SKIP
-2. Layer 1: Tier 1 → `owned`. Tier 4 extra-resource check finds Layer 2's
- resources, but they have `azd-env-name` matching the current env →
- NOT counted as extra → no veto → **DELETE**
-
-Result: Correct. The RG is deleted by the layer that created it, and
-sibling-layer resources are recognized as part of the same deployment
-environment.
-
-### Layer-Specific Deployment Name Resolution
-
-Each layer's deployment has a unique name (`{envName}-{layerName}`). The
-classifier uses the deployment associated with the current layer being
-processed. This means:
-
-- Tier 1 queries operations from the CURRENT layer's deployment only
-- Tier 2 checks tags on the RG (layer-agnostic — `azd-env-name` is shared
- across layers)
-- Tier 4's extra-resource check uses the azd-env-name-aware logic above
-
-No changes are needed to the layer iteration loop in `down.go`. The
-classification pipeline is fully layer-compatible by design.
-
-## Gap Remediation
-
-### 🚫 Anti-Pattern: Unfiltered Resource Group Deletion (Critical)
-
-**Current code** (`standard_deployments.go:429-476`):
-```go
-for resourceGroup := range resourceGroups {
- if err := ds.resourceService.DeleteResourceGroup(ctx, subscriptionId, resourceGroup); err != nil {
- // ...
- }
-}
-```
-
-**Fix**: Replace with classification-aware deletion:
-```go
-for _, classified := range classifiedGroups {
- if classified.Classification != ClassificationOwned {
- progress.SetProgress(DeleteDeploymentProgress{
- Name: classified.Name,
- Message: fmt.Sprintf("Skipping resource group %s (%s)",
- output.WithHighLightFormat(classified.Name), classified.Reason),
- State: DeleteResourceStateSkipped,
- })
- continue
- }
- // ... existing delete logic for owned RGs
-}
-```
-
-This requires adding a `DeleteResourceStateSkipped` state to the existing
-`DeleteResourceState` enum.
-
-### 🚫 Anti-Pattern: Operations() Never Used in Destroy Path (Critical)
-
-**Current state**: `Deployment.Operations()` exists in `scope.go:66` and is
-fully functional, but `BicepProvider.Destroy()` only calls
-`deployment.Resources()` — never `deployment.Operations()`.
-
-**Fix**: In the new classification pipeline, call `deployment.Operations()`
-to retrieve deployment operations and filter by `provisioningOperation`.
-
-### ⚠️ Gap: No Resource Lock Check (High)
-
-**Current state**: `DeleteResourceGroup()` in `resource_service.go:297` calls
-ARM's `BeginDelete` directly. If the RG has a lock, this fails with an error
-mid-operation — potentially after other RGs have already been deleted.
-
-**Fix**: Before entering the deletion loop, query locks for each candidate RG
-via the ARM management locks API. Skip locked RGs proactively.
-
-### ⚠️ Gap: --force Bypasses All Safety (High) — RESOLVED
-
-**Current state**: `--force` now runs Tier 1 classification (zero extra API
-calls) before deleting. External RGs identified by deployment operations
-(Read/EvaluateDeploymentOutput) are still protected even with `--force`.
-
-```go
-// --force: Tier 1 only. External RGs protected, unknowns treated as owned.
-// If operations unavailable: backward compat (all deleted).
-classifyOpts.ForceMode = true
-```
-
-**Resolution**: Tier 1 is free (parses already-fetched deployment operations).
-Running it with `--force` provides zero-cost protection for external RGs while
-preserving CI/CD semantics (no prompts, no extra API calls). Tiers 2/3/4 are
-skipped entirely in force mode. See Decision 4.
-
-### ⚠️ Gap: No Extra-Resource Detection (Medium)
-
-**Current state**: `ListSubscriptionDeploymentResources()` calls
-`ListResourceGroupResources()` to get all resources in each RG, but only uses
-the result to build the deletion list. It never compares the RG's actual
-contents against the deployment's expected contents.
+## Risks & Trade-offs
-**Fix**: Compare the resource IDs returned by `ListResourceGroupResources()`
-against the resource IDs in the deployment's `Resources()`. If the RG contains
-resources not in the deployment, flag it as a veto in Tier 4.
+### Risk 1: Snapshot Unavailable
-### 🔄 Modernization: DeleteResourceGroupDeployment Parity (Medium)
+**When**: Older Bicep CLI without `snapshot` support, non-bicepparam mode,
+snapshot errors.
-**Current state**: `DeleteResourceGroupDeployment()` at line 521 also deletes
-the RG unconditionally. For RG-scoped deployments, this is less dangerous
-(the RG is the deployment scope itself), but the same safety checks should
-apply.
+**Impact**: Falls back to conservative guard (skip all in non-interactive,
+prompt in interactive, all-owned in --force).
-**Fix**: Apply the same classification pipeline to RG-scoped deletions.
-Since there is only one RG in this case, the classification is simpler but
-should still check for locks and extra resources.
+**Mitigation**: azd bundles Bicep 0.42.1+ which supports snapshot.
+`generateBicepParam()` handles non-bicepparam case. Snapshot failure is
+effectively unreachable in normal azd flows.
-## Risks & Trade-offs
+### Risk 2: Snapshot Excludes a Created RG (False Negative)
-### Risk 1: Deployment Operations Unavailable for Old Deployments
+**When**: Bug in `bicep snapshot` implementation.
-**Severity**: Medium
+**Impact**: Medium — the created RG would not be deleted, requiring manual
+cleanup.
-**Description**: ARM has a retention limit of 800 deployments per scope. For
-very old deployments, operations data may have been purged. The Tier 1 signal
-would be unavailable.
+**Mitigation**: This is the safe failure direction. Users can re-run with
+`--force` if needed.
-**Mitigation**: Fall through to Tier 2 (tag check). For deployments created
-before this change, both Tier 1 and Tier 2 may be degraded. In that case,
-Tier 3 (interactive confirmation) activates. In `--force` mode, only Tier 1
-runs; if operations are also unavailable, all RGs are deleted (backward
-compatibility). Without `--force`, RGs with unknown provenance are
-skipped in non-interactive mode, or prompted in interactive mode.
+### Risk 3: Snapshot Includes an Existing RG (False Positive)
-### Risk 2: Performance Impact of Additional API Calls
+**When**: Bug in `bicep snapshot` where `existing` resources appear in
+`predictedResources`.
-**Severity**: Low
+**Impact**: High — would classify an external RG as owned.
-**Description**: The classification pipeline adds API calls: deployment
-operations list, resource group metadata (tags, locks, timestamps). For a
-deployment with N resource groups, this adds O(N) API calls.
+**Mitigation**: Tier 4 defense-in-depth catches this: management locks block
+deletion, and foreign-resource detection triggers a veto/prompt for resources
+without matching `azd-env-name` tags.
-**Mitigation**: N is typically small (1-5 RGs). The deployment operations
-call is a single paginated request regardless of N. RG metadata queries can
-be parallelized. The total added latency should be <5 seconds for typical
-deployments. This is acceptable for a destructive operation where safety
-trumps speed.
+### Risk 4: Backward Compatibility with Pre-Existing Deployments
-### Risk 3: False Negatives (Refusing to Delete an azd-Created RG)
+**When**: User provisioned with older azd (no snapshot tag support), now runs
+`azd down` with new azd.
-**Severity**: Medium
+**Impact**: None — snapshot is computed from the *current* template, not from
+stored deployment state. If the template still exists locally, snapshot works.
+If it doesn't, the snapshot-unavailable guard applies.
-**Description**: The multi-tier system may incorrectly classify an
-azd-created RG as `unknown` or `external` if: (a) deployment operations
-are purged, (b) tags were removed by another process, (c) the RG was
-recreated outside azd after initial provisioning.
+### Risk 5: Performance
-**Mitigation**: In interactive mode (without `--force`), `unknown` RGs
-trigger a per-RG prompt - the user can explicitly approve deletion with a
-conscious decision (default is No). In `--force` mode, only Tier 1 runs —
-unknown RGs (no operation data) are treated as owned and deleted, so false
-negatives from Tier 2/3 don't apply.
+**When**: `bicep snapshot` adds latency to `azd down`.
-### Risk 4: Backward Compatibility with Existing Deployments
+**Impact**: Low — snapshot runs locally (~1-3s), no Azure API calls.
-**Severity**: Medium
-
-**Description**: Users who have been running `azd down` successfully (because
-they only have azd-created RGs) should see no change in behavior. Users whose
-deployments reference pre-existing RGs will see new behavior (those RGs are
-now skipped).
-
-**Mitigation**: The new behavior is strictly safer — it only reduces the set
-of RGs that get deleted, never expands it. Existing workflows where all RGs
-are azd-created will classify as `owned` via Tier 1 and proceed normally.
-The only change users will notice is that pre-existing RGs are now preserved
-(which is the correct behavior).
-
-### Risk 5: Tag Spoofing in Tier 2
-
-**Severity**: Low
-
-**Description**: A malicious actor could add `azd-env-name` and
-`azd-provision-param-hash` tags to a victim resource group, causing azd
-to classify it as "owned" and delete it.
-
-**Mitigation**: Tier 2 only activates when Tier 1 is unavailable. When both
-tiers are active, Tier 1 takes precedence. Additionally, Tier 4's
-extra-resource check would likely catch this scenario — the victim RG would
-contain resources not in the deployment. Tag spoofing requires write access
-to the victim RG, which implies the attacker already has significant
-privileges.
-
-## Resolved Design Decisions
-
-### D1: No Bulk Override Flag — Per-RG Consent Only
-
-**Decision**: There is NO flag combination that bulk-deletes external resource
-groups. azd will NEVER delete a resource group it didn't create unless the user
-explicitly approves each one individually in an interactive session.
-
-**Flag behavior**:
-- `--force` — Runs Tier 1 only (zero extra API calls). External RGs identified
- by deployment operations are still protected. Unknown RGs are treated as owned.
- Tiers 2/3/4 are skipped (no prompts, no extra API calls). If deployment
- operations are unavailable, falls back to deleting all RGs (backward compat).
- See Decision 4.
-- `--purge` — Unchanged (soft-delete purging only).
-- No new flags are added.
-
-**Behavior by mode**:
-- **Interactive (no --force)**: Classification runs. Owned RGs are confirmed
- with an overall prompt. Unknown RGs get per-RG prompts with default No.
- External RGs are never deleted.
-- **Non-interactive (CI/CD, no --force)**: Classification runs. Only owned
- RGs are deleted. External/unknown RGs are skipped with logged reason.
-- **--force**: Tier 1 only. External RGs protected; unknown RGs deleted.
- No prompts, no extra API calls. Operations unavailable → all deleted.
-
-### D2: Structured Telemetry for Classification Decisions
-
-**Decision**: Emit structured telemetry events for every classification
-decision. Each event includes: resource group name, classification result
-(owned/external/unknown), tier that produced the verdict, reason string,
-and deployment name. This enables debugging user support tickets and
-measuring the safety system's effectiveness.
-
-### D3: Full Pipeline for RG-Scoped Deployments
-
-**Decision**: `DeleteResourceGroupDeployment()` runs the same full 4-tier
-classification pipeline as subscription-scoped deployments. Even though the
-RG is the deployment scope itself (and was typically created before
-`azd provision`), the classification will correctly identify it as external
-via Tier 1 (no `Create` operation for the RG in deployment operations) and
-prompt the user accordingly.
-
-### D4: Skip Purge for Resources in Skipped RGs
-
-**Decision**: When a resource group is classified as external and skipped
-during deletion, the purge flow (Key Vaults, Cognitive Services, App
-Configurations, API Management, Log Analytics Workspaces) also skips
-resources within that RG. The purge flow receives the set of skipped RG
-names and filters them out.
-
-### D5: Skip Classification When Deployment Stacks Active
-
-**Decision**: When the `FeatureDeploymentStacks` alpha flag is enabled and
-the deployment uses the `StackDeployments` code path, the classification
-pipeline is bypassed. Deployment stacks natively track managed vs unmanaged
-resources and handle this correctly. The classification pipeline only runs
-for `StandardDeployments`.
-
-### D6: Extra-Resource Veto (azd-env-name-aware, soft in interactive mode)
-
-**Decision**: The Tier 4 extra-resource check uses an absolute threshold:
-if a resource group contains ANY resource that is (a) not present in the
-current layer's deployment resource list AND (b) does not have an
-`azd-env-name` tag matching the current environment, the Tier 4 veto
-triggers. Resources from sibling layers (which share the same
-`azd-env-name` tag) are excluded from the "extra" count — this prevents
-false vetoes in layered provisioning scenarios. See the "Layered
-Provisioning Support" section for detailed scenario analysis.
-
-**Interactive mode refinement** *(from multi-model review MR-010)*: In
-interactive mode (no `--force`), the extra-resource veto is a **soft veto**:
-the user is shown the foreign resources and asked for explicit per-RG
-confirmation (default No). This handles the common case where users manually
-add experimental resources to azd-managed RGs. In non-interactive mode
-(no `--force`), the veto remains **hard** - foreign resources unconditionally
-block deletion. Note: `--force` bypasses classification entirely per
-Decision 4, so the veto check doesn't apply.
+**Mitigation**: The snapshot replaces what would have been API calls (deployment
+operations, tag fetches). Net performance is likely better.

-## Multi-Model Review Findings
-
-This design was reviewed by three independent AI models (Claude Opus 4.6,
-GPT-5.3-Codex, Goldeneye) acting as hostile critics. Below are the merged,
-deduplicated findings with their resolutions. Each finding ID uses `MR-NNN`
-(Merged Review) with the originating model(s) noted.
-
-### MR-001 [CRITICAL] — Timestamp Veto Breaks All Re-Deployment Scenarios
-**Models**: [Opus] [Codex] [Goldeneye] — unanimous consensus
-
-**Problem**: The Tier 4 rule `RG.createdTime < deployment.Timestamp → SKIP`
-is always true for re-provisioned environments. On first `azd up` (Monday),
-RG is created. On second `azd up` (Friday), deployment timestamp updates.
-`azd down` (Saturday): Monday < Friday → VETO. Every re-deployed azd
-environment becomes undeletable.
-
-Additionally, ARM SDK's `ResourceGroupProperties` does not expose
-`createdTime`; it requires raw REST `$expand=createdTime` (not in typed SDK).
-
-**Resolution**: **Removed entirely**. The timestamp sub-tier has been deleted
-from Tier 4. The remaining checks (locks + extra-resource) combined with
-Tiers 1-3 provide sufficient safety. Timestamps are too fragile and
-require SDK workarounds.
-
-### MR-002 [CRITICAL] — Classification Result Never Reaches Deletion Code
-**Models**: [Opus]
-
-**Problem**: `BicepProvider.Destroy()` calls `deployment.Delete()` →
-`DeleteSubscriptionDeployment()`, which independently re-discovers ALL RGs
-and deletes them. The classification result is architecturally disconnected
-from the code that performs deletion. Without restructuring, classification
-is dead code.
-
-**Resolution**: **Design updated** (see "Enhanced DeleteSubscriptionDeployment"
-section). Recommended approach: move the per-RG deletion loop from
-`DeleteSubscriptionDeployment()` into `BicepProvider.Destroy()`, which
-already has the classified list. `BicepProvider` calls
-`resourceService.DeleteResourceGroup()` directly for owned RGs. The
-`DeleteSubscriptionDeployment()` method becomes a thin wrapper for
-`voidSubscriptionDeploymentState()` only.
-
-### MR-003 [HIGH] — Purge Targets Computed Before Classification
-**Models**: [Goldeneye]
-
-**Problem**: `BicepProvider.Destroy()` computes Key Vault / Managed HSM /
-App Config / APIM / Cognitive / Log Analytics purge targets BEFORE the
-classification step. If an RG is later classified as external and skipped,
-its resources are still in the purge lists. D4 says "skip purge for skipped
-RGs" but the current data flow doesn't enforce this.
-
-**Resolution**: Purge target collection must happen AFTER classification, or
-the purge lists must be filtered against the `skippedRGs` set before
-execution. The implementer should:
-1. Run classification first
-2. Filter `groupedResources` to owned-only RGs
-3. Then compute purge targets from the filtered set
-This is a natural consequence of MR-002's restructuring.
-
-### MR-004 [HIGH] — Deployment Operations Not Flattened for Nested Modules
-**Models**: [Opus]
-
-**Problem**: ARM does NOT flatten nested deployment operations. If an RG is
-created inside a Bicep module, the top-level operations show the module as
-a `Microsoft.Resources/deployments` operation — no `Create` for
-`Microsoft.Resources/resourceGroups` appears at the top level.
-
-Standard azd templates declare RGs at top level (not affected), but
-user-customized templates may use module-based patterns.
-
-**Resolution**: **Design updated** (see Decision 2). Tier 1 now classifies
-as `unknown` (not `external`) when no operations of any kind are found for
-an RG, allowing fallback to Tier 2. The implementer may optionally add
-recursive operation walking for nested deployments.
-
-### MR-005 [HIGH] — Lock Check Requires New Azure Permissions
-**Models**: [Opus]
-
-**Problem**: The lock check calls `Microsoft.Authorization/locks` API which
-requires `Microsoft.Authorization/locks/read` permission. azd does not
-currently require this. Violates the "no new permissions" constraint.
-
-**Resolution**: **Design updated** — lock check is now **best-effort**. If
-the API returns 403 Forbidden, skip the lock sub-tier (do NOT veto) and log
-a warning. Alternatively, the implementer may omit the lock check entirely
-— ARM's own lock enforcement produces a clear error at deletion time.
-
-### MR-006 [HIGH] — `--force` + Degraded Tiers = Permanently Undeletable in CI
-**Models**: [Opus]
-
-**Problem**: When Tier 1 is unavailable (deployment history purged) AND
-Tier 2 fails (tags missing), Tier 3 in `--force` mode classifies as
-`external` → never deleted. D1 prohibits any override flag. CI/CD
-pipelines that use `azd down --force` for teardown silently fail to delete
-owned RGs, accumulating orphans.
-
-**Resolution**: Accept this as a deliberate safety trade-off — it's better
-to orphan RGs in CI than to risk deleting production databases. Add a clear
-log message: "Resource group 'X' could not be verified as azd-created.
-Run `azd provision` to re-establish ownership signals, then retry
-`azd down`." The `azd provision` path will create fresh deployment
-operations (Tier 1) and tags (Tier 2), enabling successful deletion.
-
-### MR-007 [HIGH] — RG-Scoped Deployments Lack Equivalent Evidence
-**Models**: [Goldeneye]
-
-**Problem**: D3 applies the full pipeline to RG-scoped deployments, but the
-evidence model is different. In RG-scoped deployments, the RG IS the
-deployment scope — there is no "RG Create operation" in deployment operations
-because the RG is the container, not a deployed resource. The current
-`DeleteResourceGroupDeployment()` directly deletes without enumeration.
-
-**Resolution**: For RG-scoped deployments, modify the pipeline:
-- Tier 1: Check if the deployment operations contain ANY `Create` operations
- for resources inside the RG. If yes, azd deployed into this RG → `owned`.
- If the RG was created OUTSIDE azd (e.g., user created it manually and set
- `AZURE_RESOURCE_GROUP`), there will be no deployment history → `unknown`.
-- Tier 2: Same tag check applies (RG tags).
-- Tier 4 extra-resource check: Compare deployment resources against actual
- RG contents (same logic).
-- Tier 3: Interactive prompt as normal.
-
-### MR-008 [HIGH] — Void Deployment State Destroys Evidence on Partial Failure
-**Models**: [Opus] [Goldeneye]
-
-**Problem**: After deleting RGs, `voidSubscriptionDeploymentState()` deploys
-an empty template that becomes the most recent deployment. On partial failure
-(e.g., 2 of 3 RGs deleted), the void deployment is created. Retry finds the
-void deployment (no resources, no operations) → "No resources found." The
-surviving RG is orphaned.
-
-**Resolution**: **Defer voiding until ALL intended deletions succeed.** If
-any deletion fails, do NOT void the deployment state. This preserves
-Tier 1 evidence for retry. The implementer should:
-1. Delete all owned RGs first (collecting errors)
-2. Only call `voidSubscriptionDeploymentState()` if all deletions succeeded
-3. On partial failure, return the error without voiding — user can retry
- `azd down` and the classification will work correctly
-
-### MR-009 [HIGH] — `--force` Can Bypass if Classification Attached to Prompting
-**Models**: [Goldeneye]
-
-**Problem**: Existing `promptDeletion()` returns `nil` immediately when
-`options.Force()` is true. If any safety logic is placed in or after the
-prompt path, `--force` bypasses it entirely.
-
-**Resolution**: Classification is separated from prompting in a dedicated
-`classifyAndDeleteResourceGroups()` function. The `--force` flag bypasses
-classification entirely (per Decision 4), deleting all RGs to preserve
-CI/CD semantics. When `--force` is not set, classification runs in full.
-This eliminates the original risk of prompt-path bypass.
-
-### MR-010 [MEDIUM] — Tier 4 Absolute Veto Blocks Interactive User Override
-**Models**: [Opus]
-
-**Problem**: Users who manually add experimental resources to azd-managed
-RGs find `azd down` refuses to clean up. The veto is absolute with no
-override path, even in interactive mode.
-
-**Resolution**: **Design updated** (see D6). In interactive mode, the
-extra-resource veto is a soft veto — user is shown the foreign resources
-and prompted per-RG. In `--force`/CI mode, it remains a hard veto.
-
-### MR-011 [MEDIUM] — Failed Deployment Cleanup Path Differs from Succeeded
-**Models**: [Goldeneye]
-
-**Problem**: `resourceGroupsFromDeployment()` has two branches: succeeded
-(uses `outputResources`) and failed (uses `dependencies`). These carry
-different fidelity. The failed path is exactly when `azd down` is most
-needed.
-
-**Resolution**: The classifier must handle both paths. For failed
-deployments:
-- `deployment.Operations()` may be partially populated — use what's
- available
-- `deployment.Dependencies` may include RGs that were never actually
- created — Tier 1 would show no `Create` op → correctly classified as
- `unknown`/`external`
-- Add explicit tests for: fail-before-RG-create, fail-after-RG-create,
- canceled deployment, and partial Operations() availability
-
-### MR-012 [MEDIUM] — Terraform Provider Not Covered
-**Models**: [Goldeneye]
-
-**Problem**: The design is ARM/Bicep-centric. azd supports Terraform where
-ownership signals come from Terraform state, not ARM deployment operations.
-
-**Resolution**: This design targets the Bicep provider (`bicep_provider.go`)
-which is the primary path. Terraform's destroy path uses `terraform destroy`
-which has its own state management. Add to Scope section: "Terraform
-provider is out of scope for this design — Terraform's state-based
-destruction already tracks which resources it manages." Future work may
-add a provider-neutral classification contract.
-
-### MR-013 [MEDIUM] — TOCTOU Window Between Classification and Deletion
-**Models**: [Codex]
-
-**Problem**: Locks/tags/resources can change between classification and
-deletion. External actors or parallel azd runs could modify state.
-
-**Resolution**: Accept as inherent to any non-transactional system.
-Mitigation: classify ALL RGs before deleting ANY (batch classification,
-then batch deletion). This minimizes the window. ARM's own lock
-enforcement provides a final safety net at deletion time.
-
-### MR-014 [MEDIUM] — ARM Throttling and Permission Edge Cases
-**Models**: [Codex] [Goldeneye]
-
-**Problem**: New API calls (operations, locks, resource enumeration) risk
-ARM 429 throttling and custom RBAC roles may allow deletion but not reads.
-
-**Resolution**: Implement retry with exponential backoff + jitter for all
-ARM calls. Distinguish 403 (skip check, log warning) from 429 (retry)
-from 5xx (retry with backoff). Use goroutines with a semaphore for parallel
-per-RG Tier 4 checks. See Implementation Guide.
-
-### MR-015 [LOW] — ARM SDK Pointer Types Require Nil Guards
-**Models**: [Opus]
-
-**Problem**: `DeploymentOperationProperties.ProvisioningOperation`,
-`TargetResource`, and `TargetResource.ResourceType` are all pointer types.
-Existing tests set `ProvisioningState` but not these fields, confirming
-they can be nil.
-
-**Resolution**: Mandate nil checks for all pointer fields before comparison.
-Skip operations where any required field is nil. See Implementation Guide.
-
-### MR-016 [LOW] — Per-RG Prompting UX at Scale
-**Models**: [Goldeneye]
-
-**Problem**: Per-RG prompts don't scale for 10+ RGs across layers.
-
-**Resolution**: Show a summary table of all classification decisions first:
-```
-Resource Groups to delete:
- ✓ rg-app (azd-created, Tier 1)
- ✓ rg-web (azd-created, Tier 1)
- ✗ rg-shared-db (pre-existing, skipped)
- ? rg-experiment (unknown — contains 2 extra resources)
-```
-Then prompt ONCE for the unknown set: "Delete 1 unverified resource group?
-(y/N)" For owned RGs, show total count and confirm once (unless `--force`).
-
-### MR-017 [LOW] — Go Concurrency Footgun in Parallel Checks
-**Models**: [Codex]
-
-**Problem**: Parallel per-RG metadata queries writing to shared maps/slices
-can cause `concurrent map writes` panics.
-
-**Resolution**: Use immutable per-worker results + channel fan-in pattern.
-Each goroutine returns its `ClassifiedResourceGroup` via a channel. The
-collector assembles the final slice. Run with `-race` in CI. See
-Implementation Guide.
-
-## Implementation Guide for Developers
-
-### Tip 1: Restructure the Deletion Flow (MR-002 — CRITICAL, do this first)
-
-The single most important structural change: move the deletion loop from
-`DeleteSubscriptionDeployment()` into `BicepProvider.Destroy()`.
-
-```
-Current flow:
- BicepProvider.Destroy() → deployment.Delete() → DeleteSubscriptionDeployment()
- → re-discovers RGs → deletes ALL
-
-New flow:
- BicepProvider.Destroy()
- → deployment.Resources() (already called)
- → GroupByResourceGroup() (already called)
- → ClassifyResourceGroups() (NEW)
- → for each owned RG: resourceService.DeleteResourceGroup()
- → voidSubscriptionDeploymentState() (only if all succeeded)
-```
-
-`deployment.Delete()` should be refactored or a new path created. The
-classifier needs access to `deployment.Operations()` and
-`resourceService.ListResourceGroupResources()` — pass these as
-dependencies to the classifier constructor.
-
-### Tip 2: ARM SDK Nil Guard Pattern
-
-Every field access on `DeploymentOperation` must be guarded:
-
-```go
-for _, op := range operations {
- if op.Properties == nil ||
- op.Properties.ProvisioningOperation == nil ||
- op.Properties.TargetResource == nil ||
- op.Properties.TargetResource.ResourceType == nil ||
- op.Properties.TargetResource.ResourceName == nil {
- continue // skip incomplete operations
- }
- if *op.Properties.ProvisioningOperation == armresources.ProvisioningOperation("Create") &&
- *op.Properties.TargetResource.ResourceType == "Microsoft.Resources/resourceGroups" {
- ownedRGs[*op.Properties.TargetResource.ResourceName] = true
- }
-}
-```
-
-### Tip 3: Tier Evaluation Order and Short-Circuiting
-
-Consider reordering the tiers for performance. The design says Tier 4
-(vetoes) runs first, but Tier 1 (deployment operations) is a SINGLE
-API call that covers ALL RGs at once. Suggested implementation order:
-
-```
-1. Call deployment.Operations() once (Tier 1 data, 1 API call for all RGs)
-2. For each RG:
- a. Run Tier 1 classification from cached operations
- b. If classified "owned" → run Tier 4 veto checks (extra-resource, locks)
- c. If classified "external" → skip (no Tier 4 needed)
- d. If Tier 1 unavailable → run Tier 2 (tags), then Tier 4 if "owned"
- e. If still unknown → Tier 3 (prompt or skip)
-```
-
-This way, Tier 4's per-RG API calls (resource enumeration, locks) only
-run for RGs that are candidates for deletion — typically 1-3 RGs, not all
-referenced RGs.
-
-### Tip 4: Parallelize Tier 4 Per-RG Checks
-
-```go
-type classifyResult struct {
- name string
- classification ResourceGroupClassification
- tier int
- reason string
- err error
-}
-
-results := make(chan classifyResult, len(rgNames))
-sem := make(chan struct{}, 5) // limit to 5 concurrent ARM calls
-
-for _, rg := range rgNames {
- go func(rgName string) {
- sem <- struct{}{}
- defer func() { <-sem }()
- // run Tier 4 checks for this RG
- results <- classifyResult{...}
- }(rg)
-}
-
-classified := make([]ClassifiedResourceGroup, 0, len(rgNames))
-for range rgNames {
- r := <-results
- classified = append(classified, ...)
-}
-```
-
-### Tip 5: Handle Both Deployment States (Succeeded vs Failed)
-
-`resourceGroupsFromDeployment()` has two branches. Your classifier
-receives the RG names from this function regardless of which branch
-produced them. For FAILED deployments:
-- `deployment.Operations()` may be partially populated — use it
-- Some RGs in the candidate set may never have been created — Tier 1
- will show no Create op (correct: `unknown`/`external`)
-- `DeleteResourceGroup()` for a non-existent RG returns 404 — handle
- this as success (already gone), not as a fatal error
-
-### Tip 6: Testing Strategy
-
-Use the existing `mocks.NewMockContext` and `mockexec.MockCommandRunner`
-patterns. The classifier is highly testable because each tier is a
-discrete function:
-
-```
-Test matrix:
-- Tier 1: Create op found / Read op found / No ops / API error / nil fields
-- Tier 2: Both tags / one tag / no tags / wrong env name / API error
-- Tier 4: No extra resources / extra with azd tag / extra without tag /
- lock present / lock check 403
-- Tier 3: Interactive approve / deny / --force mode
-- Cross-tier: Tier 4 veto overrides Tier 1 owned / Tier 1 unavailable falls
- to Tier 2 / All tiers degrade gracefully
-- Layered: Scenario 1/2/3 from architecture doc
-- Failed deployments: fail-before-RG-create / fail-after / canceled
-- Partial deletion: RG1 succeeds, RG2 fails, void NOT called
-```
-
-### Tip 7: `--force` Bypasses Classification (Decision 4)
-
-Per Decision 4, `--force` bypasses the entire classification pipeline and
-deletes all discovered RGs. This preserves original CI/CD semantics.
-Classification only runs when `--force` is not set.
-
-```go
-// --force: bypass classification, delete all RGs
-if options.Force() {
- deleted, err = deleteRGList(ctx, subId, rgNames, ...)
- return deleted, nil, err
-}
-
-// No --force: run full classification pipeline
-classified := ClassifyResourceGroups(ctx, ops, rgNames, opts)
-// prompt for owned RGs, skip external/unknown
-```
-
-### Tip 8: Void State Only After Full Success
-
-```go
-// Delete all owned RGs, collecting results
-var deleteErrors []error
-for _, rg := range ownedRGs {
- if err := resourceService.DeleteResourceGroup(ctx, subId, rg.Name); err != nil {
- deleteErrors = append(deleteErrors, fmt.Errorf("deleting %s: %w", rg.Name, err))
- }
-}
-
-// Only void if ALL succeeded
-if len(deleteErrors) == 0 {
- if err := voidSubscriptionDeploymentState(ctx, subId, deploymentName, opts); err != nil {
- return fmt.Errorf("voiding deployment state: %w", err)
- }
-} else {
- return errors.Join(deleteErrors...)
-}
-```
-
-### Tip 9: Tag Access Requires Code Change in ResourceService
-
-The existing `ResourceService.ListResourceGroup()` (resource_service.go)
-strips tags from the response. The classifier needs RG tags for Tier 2 and
-Tier 4 (azd-env-name on extra resources). Either:
-- Add a `GetResourceGroupWithTags()` method that preserves the ARM response's
- `Tags` field
-- Or modify `Resource` struct to include `Tags map[string]*string`
-
-Similarly, `ListResourceGroupResources()` returns `ResourceExtended` which
-includes tags — verify this is sufficient for the Tier 4 extra-resource
-check on individual resources.
-
-### Tip 10: Error Handling for ARM API Degradation
-
-Each Tier's ARM calls can fail independently. Handle per the fail-safe
-principle:
-
-| API Call | 403 | 404 | 429 | 5xx |
-|----------|-----|-----|-----|-----|
-| Operations | Fall to Tier 2 | Fall to Tier 2 | Retry 3x | Retry 3x |
-| RG Locks | Skip lock check | Skip lock check | Retry 3x | Retry 3x |
-| RG Resources | SKIP (veto — cant verify) | SKIP | Retry 3x | Retry 3x |
-| RG Tags | Fall to Tier 3 | Fall to Tier 3 | Retry 3x | Retry 3x |
-
-Never let an API error convert to "owned" — errors always fail safe
-toward skip/unknown.

-### Contributor Review Panel
-
-#### Victor Vazquez (@vhvb1989)
-
-**Verdict**: REQUEST CHANGES — Telemetry design is non-negotiable for a safety
-feature.
-
-**Findings**:
-
-1. **[CR-001 HIGH] No telemetry design for classification outcomes** —
- The 4-tier pipeline makes critical delete-vs-skip decisions, but zero tracing
- spans or telemetry events are specified. When a user reports "azd down skipped
- my RG and I don't know why", there's nothing to inspect. Every classification
- result (`owned`/`external`/`unknown`/`vetoed`) MUST emit a span with attributes:
- `rg.name`, `tier.decided`, `classification`, `reason`.
-
- **Resolution**: Added **Tip 11** — Telemetry Instrumentation requirement.
- Each classification decision emits a structured trace span. The overall
- `Destroy()` operation emits a summary span with owned/skipped/vetoed counts.
-
-2. **[CR-002 HIGH] Error classification for new ARM calls is unspecified** —
- `ManagementLockClient` is never used in this codebase. What `ResponseError`
- codes does it return beyond 403? Sentinel errors need defining, following the
- `ErrDeploymentNotFound` pattern at `standard_deployments.go:293-297`.
-
- **Resolution**: Added to **Tip 10** — define `ErrLockCheckFailed` sentinel
- with structured wrapping. Lock check errors fall through (skip check), never
- escalate to hard failure.
-
-3. **[CR-003 MEDIUM] Tier 1 `provisioningOperation` string comparison needs nil
- safety** — ARM SDK returns `*string`. Raw dereference panics on nil. Use a
- helper `operationIs(op, "Create") bool` or Go 1.26's nil-safe patterns.
-
- **Resolution**: Already covered in **Tip 2** (ARM SDK Nil Guard Pattern).
- Added: extract `operationIs()` helper to centralize nil-safe checks.
-
-4. **[CR-004 LOW] Extra-resource check calls ListResourceGroupResources for every
- candidate RG** — Each is a paged enumeration. For N candidate RGs, that's N
- paging calls before classification. Consider cheaper signals or batching.
-
- **Resolution**: Addressed by **Tip 3** ordering — Tier 4 only runs on RGs
- already classified "owned" by Tier 1, dramatically reducing API calls.
-
-#### Wei Lim (@nicklhw)
-
-**Verdict**: APPROVE WITH COMMENTS — Design is sound but needs an API call
-budget table.
-
-**Findings**:
-
-5. **[CR-005 HIGH] API call explosion in classification pipeline** — Worst case
- per RG: lock check (1 call) + extra-resource check (1+ paged) + Tier 1 ops
- (1+ paged) + Tier 2 tags (1 GET). For 5 RGs, that's 15+ calls vs zero today.
- Must specify parallelization strategy and timeout budget.
-
- **Resolution**: Added **Tip 12** — API Call Budget with worked examples.
- Tier 1 is ONE call for ALL RGs (shared operations list). Tier 4 only runs
- on "owned" candidates. Parallel Tier 4 with semaphore. Expected: 3-5 calls
- for typical deployment vs 15+ worst case.
-
-6. **[CR-006 HIGH] Tier 1 is one API call with client-side filtering, not N
- calls** — `ListSubscriptionDeploymentOperations` returns ALL operations for
- the deployment. The design reads as though each RG triggers a separate call.
-
- **Resolution**: Clarified in architecture — Tier 1 section now explicitly
- states: "Single API call, client-side filter by resource type and operation
- type." Already reflected in **Tip 3** ordering.
-
-7. **[CR-007 MEDIUM] Paging completeness for lock enumeration** — Lock-list must
- handle `pager.More()/NextPage()` pattern. Reading only page 1 misses locks on
- RGs with many locked resources.
-
- **Resolution**: Added note to **Tip 2** — all new ARM list calls must use
- the standard pager exhaustion pattern per `standard_deployments.go:291-300`.
-
-8. **[CR-008 MEDIUM] Progress display during classification** — Currently shows
- spinner "Discovering resources..." with no progress updates during the
- (potentially long) classification phase. Users see a stalled spinner.
-
- **Resolution**: Added **Tip 13** — Progress UX. Classification phase shows
- per-RG progress: "Classifying rg-app... (owned)", "Classifying rg-db...
- (external — skipping)". Uses existing `async.Progress[T]` pattern.
-
-9. **[CR-009 LOW] Operation list caching opportunity** — Tier 1 fetches the full
- operations list. Same data is used later for progress display. Cache to avoid
- redundant fetch.
-
- **Resolution**: Noted in **Tip 3** — operations list should be cached and
- passed to both classifier and progress display.
-
-#### Wallace Breza (@wbreza)
-
-**Verdict**: REQUEST CHANGES — Need stacks graduation migration plan and
-`DeploymentService` interface resolution.
-
-**Findings**:
-
-10. **[CR-010 HIGH] Classifier creates a parallel ownership model that complicates
- stacks graduation** — When deployment stacks GA, they provide native ARM-level
- resource ownership. The 4-tier classifier builds client-side ownership using
- ops+tags+heuristics. These will diverge. Will the classifier persist "because
- some users haven't migrated"?
-
- **Resolution**: Added **Section: Stacks Graduation Migration Plan** (below).
- Explicit sunset: when stacks reach GA, classifier is deprecated. Migration
- path: `azd config set alpha.deploymentStacks on` → behavior equivalent.
- Classifier code remains but emits deprecation warning after stacks GA.
-
-11. **[CR-011 HIGH] `DeploymentService` interface asymmetry after MR-002** —
- `DeleteSubscriptionDeployment` becomes a thin void wrapper, but
- `DeleteResourceGroupDeployment` still directly deletes. One `Delete*` voids
- and the other deletes — confusing for every future reader.
-
- **Resolution**: Rename `DeleteSubscriptionDeployment` to
- `VoidSubscriptionDeploymentState` to reflect its new semantics. Add a
- matching `VoidResourceGroupDeploymentState` for the RG-scoped path.
- Both deletion loops live in `BicepProvider.Destroy()`. Updated in
- **Tip 1** (Restructure Deletion Flow).
-
-12. **[CR-012 MEDIUM] Extension framework interaction** — Extensions via gRPC
- can hook into lifecycle events. If the classifier runs inside
- `BicepProvider.Destroy()`, extensions that implement custom destroy logic
- won't have access to classification results.
-
- **Resolution**: Classification results should be included in the
- `DestroyOptions` context. Extensions creating resources in shared RGs can
- annotate them with `azd-env-name` tags to avoid false vetoes. Documented
- as a known consideration — full extension API integration deferred to
- follow-up.
-
-13. **[CR-013 MEDIUM] Per-RG prompt breaks existing UX contract** — Today there's
- ONE confirmation prompt. Adding per-RG prompts for "unknown" classification
- means N additional prompts — UX regression.
-
- **Resolution**: Added **Tip 14** — Batch UX. Unknown RGs are batched into a
- single multi-select prompt: "The following resource groups have unknown
- ownership: [list]. Select which to delete: [ ] rg-a [ ] rg-b [none]".
- Default: none selected.
-
-14. **[CR-014 LOW] Environment caching interaction** — Env caching (#6076) may
- serve stale `azd-env-name` values. If user changed env name, Tier 2 tag
- matching produces wrong results.
-
- **Resolution**: Tier 2 compares live ARM tags against the current env name
- from `environment.GetEnvName()`, not cached values. Documented as a note
- in Tier 2 description.
-
-#### Matt Ellis (@ellismg)
-
-**Verdict**: REQUEST CHANGES — Minimize exported types. Prove each one earns
-its keep.
-
-**Findings**:
-
-15. **[CR-015 HIGH] Over-abstraction — "4-Tier Pipeline" introduces too many
- types** — Classifier struct, result type, classification enum, tier
- interfaces? Can this be a single function
- `classifyResourceGroups(ctx, deployment, rgNames) (owned, skipped []string, err error)`
- with tiers as internal implementation?
-
- **Resolution**: Accepted. The classifier SHOULD be a function, not a type.
- The tiers are implementation details. Exported API is:
-
- ```go
- // Package-level function, not a struct method
- func ClassifyResourceGroups(
- ctx context.Context,
- deployment Deployment,
- rgNames []string,
- opts ClassifyOptions,
- ) (ClassifyResult, error)
-
- type ClassifyResult struct {
- Owned []string
- Skipped []ClassifiedSkip // name + reason for UX
- }
-
- type ClassifiedSkip struct {
- Name string
- Reason string // "external (Tier 1: deployment ops)", etc.
- }
-
- type ClassifyOptions struct {
- Interactive bool
- EnvName string
- Prompter func(rgName, reason string) (bool, error)
- }
- ```
-
- Tiers are unexported helper functions. No tier interfaces. Updated in
- **Tip 15** — Minimal Type Surface.
-
-16. **[CR-016 HIGH] Pointer field nil safety requires an extraction helper** —
- ARM SDK's `DeploymentOperation` fields are all pointers. Demand a helper
- `operationIs(op, "Create") bool` rather than inline nil checks everywhere.
-
- **Resolution**: Already covered by CR-003 and **Tip 2**. Consolidated:
- `operationIs()` helper is mandatory, not optional.
-
-17. **[CR-017 MEDIUM] New `ManagementLockClient` dependency widens import graph**
- — Check whether lock types are in the existing `armresources` package or a
- new module. Don't import a whole new ARM module for a best-effort check.
-
- **Resolution**: `ManagementLockClient` is in the existing
- `github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/resources/armlocks`
- package — this IS a new import. Justified because lock detection is critical
- for safety. Documented as an accepted import addition.
-
-18. **[CR-018 MEDIUM] Classification enum should be a Go type, not raw strings**
- — Define `type Classification string` with constants. Raw string comparisons
- are fragile.
-
- **Resolution**: Already in the design. Per CR-015, the exported API uses
- `ClassifiedSkip.Reason` (string for human display) while internal logic
- uses typed constants: `const classOwned classification = "owned"` (unexported).
-
-19. **[CR-019 LOW] `bicep_provider.go` is already 1300+ lines — consider
- `bicep_destroy.go`** — After MR-002 moves the deletion loop + classification
- into `Destroy()`, the file grows further.
-
- **Resolution**: Accepted. Extract destroy-related methods into
- `bicep_destroy.go` in the same package. Updated in **Tip 1**.
-
-#### hemarina
-
-**Verdict**: REQUEST CHANGES — Failed-deployment path and RG-scoped adaptation
-are underspecified.
-
-**Findings**:
-
-20. **[CR-020 HIGH] `resourceGroupsFromDeployment` failed-deployment fallback
- bypasses classification** — Lines 383-397: when `ProvisioningState !=
- Succeeded`, RGs are extracted from `Dependencies` which conflates owned and
- external. If the last deployment failed, Tier 1 operations may be incomplete.
-
- **Resolution**: Added **Tip 16** — Failed Deployment Handling. For failed
- deployments:
- - Tier 1 still runs (operations are available even for failed deployments)
- - If operations are incomplete, classification falls to Tier 2/3
- - The dependency-extracted RG list is treated as "candidates" only — every
- candidate still goes through the full classification pipeline
- - Never shortcut classification based on provisioning state
-
-21. **[CR-021 HIGH] Partial deletion + void timing interaction** — 3 RGs
- classified "owned". RG1 deletes ok. RG2 fails (lock added after
- classification). RG3 never attempted. Next retry: `resourceGroupsFromDeployment`
- still references RG1 (deleted). Classifier tries to check a deleted RG.
- Lock check → 404, tag check → 404...
-
- **Resolution**: Added to **Tip 10** error handling: 404 on RG during
- classification → classify as "already deleted" → skip (not an error).
- Added `ClassificationAlreadyDeleted` internal status. No void on partial
- failure is already specified (MR-008).
-
-22. **[CR-022 MEDIUM] RG-scoped deployment has fundamentally different structure**
- — `DeleteResourceGroupDeployment` takes `resourceGroupName` — it already
- knows the RG. Classification there is about resources *inside* the RG, not
- RG ownership. Tier 1 is irrelevant, Tier 2 is on the known RG, and only
- Tier 4 extra-resource check is meaningful.
-
- **Resolution**: Added **Tip 17** — RG-Scoped Adaptation. For RG-scoped:
- - Skip Tier 1 (N/A — RG identity known)
- - Run Tier 2 tag check on the RG itself
- - Run Tier 4 extra-resource check (are all resources in this RG azd-owned?)
- - Run Tier 3 prompt if uncertain
- - The classifier function accepts a `scope` parameter to select the
- appropriate tier subset
-
-23. **[CR-023 MEDIUM] "Read → external" heuristic needs nuance** — `Read` in
- deployment operations can mean "template declared RG as `existing`" OR
- "template referenced a resource that happens to be in this RG". These are
- different — first is clearly external, second might be a nested dependency
- in an owned RG.
-
- **Resolution**: Clarified Tier 1 logic: `Read` on
- `Microsoft.Resources/resourceGroups` → external. `Read` on other resource
- types in an RG → does NOT classify the parent RG as external. Only
- RG-level operations drive RG classification.
-
-24. **[CR-024 LOW] Cross-layer Tier 4 misses untagged sibling-layer RGs** —
- Older azd versions created RGs without `azd-env-name` tags. Name-convention
- fallback (`rg-{env}` / `{env}-rg`) needed.
-
- **Resolution**: Added to Tier 4 cross-layer section: if RG lacks
- `azd-env-name` tag, also check name convention patterns from
- `azure_resource_manager.go:272-297` before classifying as foreign.

-### Go Expert Review Panel
-
-#### Standard Library Purist
-
-**Verdict**: APPROVE WITH COMMENTS
-
-**Findings**:
-
-25. **[GO-001 HIGH] Interface bloat risk** — If `ResourceGroupOwnershipClassifier`
- mirrors the 110+ line `DeploymentService` interface, it's too big. Prefer
- function injection or tiny interfaces.
-
- **Resolution**: Resolved by CR-015. The classifier is a function, not a
- type. Dependencies are passed via `ClassifyOptions` or as function
- parameters. No new interface needed.
-
-26. **[GO-002 MEDIUM] Stringly-typed tier logic** — `"Create"` / resource type
- checks need centralized, typed helpers.
-
- **Resolution**: Covered by CR-003/CR-016. The `operationIs()` helper
- centralizes string comparisons with `strings.EqualFold` for case safety.
-
-27. **[GO-003 MEDIUM] Error context quality** — Every tier error must be wrapped
- with RG/deployment/tier context.
-
- **Resolution**: Added to **Tip 10**: all errors wrapped with
- `fmt.Errorf("classify rg=%s tier=%d: %w", rgName, tier, err)`.
-
-#### Production Systems Engineer
-
-**Verdict**: REQUEST CHANGES
-
-**Findings**:
-
-28. **[GO-004 HIGH] Missing end-to-end timeout budget** — Per-call retries without
- a global deadline can hang `azd down` indefinitely.
-
- **Resolution**: Added **Tip 12** — classification phase gets a global
- `context.WithTimeout(ctx, 2*time.Minute)`. Individual ARM calls inherit
- this context. If timeout expires, all pending classifications fail safe to
- "unknown" → Tier 3 prompt or CI skip.
-
-29. **[GO-005 HIGH] Retry amplification risk** — Parallel goroutines × SDK
- retries × custom retries = thundering herd potential.
-
- **Resolution**: Clarified in **Tip 12**: do NOT add custom retry loops.
- Rely on Azure SDK's built-in retry policy (`azcore.ClientOptions.Retry`).
- The semaphore limits concurrency to 5 parallel Tier 4 checks. No custom
- retry on top of SDK retry.
-
-30. **[GO-006 MEDIUM] Insufficient operator observability** — Need structured
- per-RG decision logs with tier outcomes and fallback path.
-
- **Resolution**: Covered by CR-001 (telemetry) + **Tip 11**. Structured
- logging at DEBUG level + trace spans for each classification decision.
-
-31. **[GO-007 MEDIUM] Incident escape hatch** — No "safe mode" for ARM incidents.
-
- **Resolution**: Existing mechanisms suffice: `--force` skips prompts for
- owned only (safe by design). If ARM is degraded, classification falls to
- Tier 3 (prompt) or CI refuses to delete unknowns. No additional escape
- hatch needed — the fail-safe design IS the escape hatch.
-
-#### Azure SDK Specialist
-
-**Verdict**: REQUEST CHANGES
-
-**Findings**:
-
-32. **[GO-008 HIGH] Tier 1 signal may be brittle** —
- `ProvisioningOperation=="Create"` for RG ownership is not universally stable.
- Case sensitivity matters. Validate against real payloads.
-
- **Resolution**: Use `strings.EqualFold` for all ARM enum comparisons.
- Added to **Tip 2**: the `operationIs()` helper MUST use case-insensitive
- comparison. Additionally, validate the expected value against real ARM
- responses during testing (add integration test with recorded cassette).
-
-33. **[GO-009 HIGH] Locks API specifics — pagination** — Management locks are
- paged at RG scope. Must handle full pagination before declaring "no lock."
-
- **Resolution**: Covered by CR-007. Standard pager exhaustion pattern is
- mandatory for all new ARM list calls.
-
-34. **[GO-010 MEDIUM] Double-retry policy** — Azure SDK already retries 429/5xx.
- Custom retry wrapper would over-delay and over-load.
-
- **Resolution**: Covered by GO-005. No custom retry. SDK retry is sufficient.
- Remove "Retry 3x" from the error handling table — replace with "SDK retry
- (built-in)" to clarify that no custom retry logic is added.
-
-35. **[GO-011 MEDIUM] `ResourceGroupsClient.Get()` tag behavior** — Verify that
- `.Tags` is populated by default. Do not rely on `createdTime`.
-
- **Resolution**: Confirmed — `ResourceGroupsClient.Get()` returns `Tags` by
- default in `armresources.ResourceGroup`. No extra parameters needed.
- `createdTime` was already removed from the design (MR-001 removed timestamp
- veto entirely).

-### Additional Tips (11-17)
-
-### Tip 11: Telemetry Instrumentation (CR-001)
-
-Every classification decision MUST emit structured telemetry:
-
-```go
-// In the classify function, after each RG is classified:
-tracing.SetSpanAttributes(ctx,
- attribute.String("rg.name", rgName),
- attribute.String("classification", string(result)),
- attribute.Int("tier.decided", tierNumber),
- attribute.String("reason", reason),
-)
-
-// Summary span on the overall Destroy() operation:
-tracing.SetSpanAttributes(ctx,
- attribute.Int("rg.owned.count", len(owned)),
- attribute.Int("rg.skipped.count", len(skipped)),
- attribute.Int("rg.vetoed.count", vetoedCount),
-)
-```
-
-At DEBUG log level, emit human-readable lines:
-
-```
-DEBUG classify rg=rg-app tier=1 decision=owned reason="Create operation found"
-DEBUG classify rg=rg-db tier=1 decision=external reason="Read operation only"
-```
-
-This is non-negotiable for a safety-critical feature. Operators must be able
-to trace exactly why any RG was or wasn't deleted.
-
-### Tip 12: API Call Budget and Timeout (CR-005, GO-004, GO-005)
-
-**Global timeout**: Classification phase gets `context.WithTimeout(ctx, 2*time.Minute)`.
-If timeout fires, all pending classifications fail safe to "unknown".
-
-**No custom retry**: Rely on Azure SDK's built-in retry policy only.
-Do NOT wrap ARM calls in custom retry loops — this causes retry amplification
-when combined with SDK retries and parallel goroutines.
-
-**Parallelization**: Tier 4 checks run with a semaphore (buffered channel,
-capacity 5). Tier 1 is a single shared call — no parallelization needed.
-
-**Expected API call counts**:
-
-| Scenario | Tier 1 | Tier 4 (locks) | Tier 4 (resources) | Tier 2 (tags) | Total |
-|----------|--------|----------------|--------------------| --------------|-------|
-| 1 RG, owned | 1 | 1 | 1 | 0 | 3 |
-| 5 RGs, 3 owned 2 external | 1 | 3 | 3 | 0 | 7 |
-| 5 RGs, all unknown (Tier 1 fails) | 1 | 0 | 0 | 5 | 6 |
-| 3 layers × 2 RGs | 3 | ~3 | ~3 | 0 | ~9 |
-
-Note: Tier 4 only runs on "owned" candidates (after Tier 1). External and
-unknown RGs skip Tier 4 entirely.
-
-### Tip 13: Progress UX During Classification (CR-008)
-
-The classification phase can take several seconds. Show per-RG progress:
-
-```
-Classifying resource groups...
- rg-app: owned (deployment created)
- rg-db: external (referenced only) — will skip
- rg-shared: checking...
-```
-
-Use the existing `async.Progress[T]` pattern. The classification progress
-sits between "Discovering resources..." and the deletion confirmation prompt.
-
-### Tip 14: Batch Unknown RG Prompt (CR-013)
-
-Do NOT show N sequential yes/no prompts for unknown RGs. Batch into one
-multi-select:
-
-```
-The following resource groups have unknown ownership (azd couldn't determine
-if it created them). Select which to delete:
-
- [ ] rg-shared-infra (contains 12 resources, no azd tags)
- [ ] rg-network (contains 3 resources, partial azd tags)
-
-Default: none selected (safest option)
-> Select: _
-```
-
-In `--force` / CI mode: unknown RGs are NEVER deleted (no prompt shown).
-
-### Tip 15: Minimal Type Surface (CR-015)
-
-Export only what consumers need. The classifier is a function, not a type:
-
-```go
-// Exported — the public API
-func ClassifyResourceGroups(
- ctx context.Context,
- ops []armresources.DeploymentOperation,
- rgNames []string,
- opts ClassifyOptions,
-) (ClassifyResult, error)
-
-type ClassifyOptions struct {
- Interactive bool
- EnvName string
- Prompter func(rgName, reason string) (bool, error)
- // ARM clients passed as function-typed fields, not interfaces
- ListLocks func(ctx context.Context, rg string) ([]Lock, error)
- ListResources func(ctx context.Context, rg string) ([]Resource, error)
- GetRGTags func(ctx context.Context, rg string) (map[string]*string, error)
-}
-
-type ClassifyResult struct {
- Owned []string
- Skipped []ClassifiedSkip
-}
-
-type ClassifiedSkip struct {
- Name string

-
-Unexported helpers implement the tiers:
-
-```go
-func classifyTier1(ops []armresources.DeploymentOperation, rg string) classification { ... }
-func classifyTier2(tags map[string]*string, envName string) classification { ... }
-func checkTier4Locks(ctx context.Context, listLocks lockLister, rg string) (bool, error) { ... }
-func checkTier4ExtraResources(ctx context.Context, listRes resLister, rg, envName string) (bool, error) { ... }
-```
-
-No `ResourceGroupOwnershipClassifier` struct. No tier interfaces. The
-function signature IS the contract.
-
-### Tip 16: Failed Deployment Handling (CR-020)
-
-When `deployment.ProvisioningState != Succeeded`:
-
-1. `resourceGroupsFromDeployment` extracts RGs from `Dependencies` (broader,
- includes `existing` references) — these are **candidates only**
-2. Classification pipeline runs on ALL candidates (never skip classification
- because the deployment failed)
-3. Tier 1 operations ARE available for failed deployments — ARM records ops
- even for partially-completed deployments
-4. If operations list is empty/incomplete, Tier 1 returns "unknown" → falls
- to Tier 2 tags
-5. Never refuse to run `azd down` because of a failed deployment — the user
- may be trying to clean up after a failure
-
-```go
-// Candidate extraction doesn't change
-rgNames := resourceGroupsFromDeployment(deployment)
-
-// Classification ALWAYS runs regardless of provisioning state
-result, err := ClassifyResourceGroups(ctx, ops, rgNames, opts)
-```
-
-### Tip 17: RG-Scoped Adaptation (CR-022)
-
-For `DeleteResourceGroupDeployment` (RG-scoped), the pipeline adapts:
-
-| Tier | Subscription-Scoped | RG-Scoped |
-|------|---------------------|-----------|
-| 1 (Operations) | Filter ops for RG Create | **Skip** (RG identity known) |
-| 2 (Tags) | Check both azd tags | Check azd tags on the known RG |
-| 4 (Locks) | Check per candidate | Check on the known RG |
-| 4 (Extra resources) | Check per candidate | **Primary check** — are all resources azd-owned? |
-| 3 (Prompt) | Per-RG for unknowns | Single prompt for the known RG |
-
-The `ClassifyOptions` gains a `Scope` field:
-
-```go
-type ClassifyScope int
-const (
- ScopeSubscription ClassifyScope = iota
- ScopeResourceGroup
-)
-```
-
-For RG-scoped, the function receives a single-element `rgNames` slice and
-skips Tier 1. Tier 4 extra-resource check becomes the primary signal.
-
-### Stacks Graduation Migration Plan (CR-010)
-
-**Current state**: Deployment stacks are alpha (`alpha.deploymentStacks`).
-The classifier is the safety net for the default `StandardDeployments` path.
-
-**When stacks reach GA**:
-1. `StandardDeployments` path emits a deprecation notice: "Consider enabling
- deployment stacks for native resource ownership tracking"
-2. Classifier continues to work for existing users (no forced migration)
-3. After 2 major versions post-stacks-GA: classifier emits a warning
- that it will be removed in the next major version
-4. Eventual removal: classifier code deleted, `StandardDeployments.Delete*`
- methods removed, all users on stacks
-
-**Design principle**: The classifier is a **bridge** to stacks GA, not a
-permanent parallel system. It should be simple enough to delete without
-ceremony when the time comes — which is another reason to keep the type
-surface minimal (Tip 15).
