The Diff detected debug line printed the Go syntax of the whole terraform.InstanceDiff, which is hard to read for resources with many nested attributes. Log the old and the planned values as two flat maps instead, so the two sides can be diffed, with computed values marked and sensitive values redacted.

607-617: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winUse named table cases for the attribute behaviors.
Could you give changed, computed, removed, and sensitive attributes separate named cases with
argsandwantfields? The combined fixture makes a failed redaction assertion harder to attribute to one attribute behavior. It also makes the schema-sensitive regression cases requested above harder to add. Thank you for comparing maps rather than relying on iteration order.As per path instructions, “Enforce table-driven test structure: PascalCase test names (no underscores), args/want pattern.”

934-934: 🔒 Security & Privacy | 🔵 Trivial | 🏗️ Heavy liftRedact schema-sensitive values independently of
ResourceAttrDiff.Sensitive.Terraform Plugin SDK v2.37.0 returns removed diffs before setting
Sensitive. It also builds collection element diffs from element schemas without copying the parent collection’s sensitivity.instanceDiffValuescan therefore add raw schema-sensitive values to the maps passed toDebug.This is not a new leak from this PR. The merge base already emitted raw
OldandNewvalues throughinstanceDiff.GoString(), including values whoseSensitiveflag was set. The new code improves redaction for flagged attributes but leaves this SDK sensitivity gap.Could you check sensitivity along the Terraform schema path and add regression cases for removed sensitive attributes and sensitive collections?

The SDK sets the Sensitive flag of an attribute diff in finalizeDiff, which returns early for removed attributes, and the element schemas it builds for lists and sets copy only ForceNew from the parent. Resolve sensitivity along the schema path as well, so removed secrets and the elements of sensitive collections are redacted in the Diff detected log line. The test is table-driven with a case per attribute behavior. Signed-off-by: Youssef Omar Bouden <youssef.bouden2002@gmail.com>

Could we keep distinct opaque identifiers for set elements that contain sensitive fields? Terraform SDK v2.37.0 emits keys such as
block.<hash>.name.sensitiveKeychanges bothblock.<hash1>.nameandblock.<hash2>.nametoblock.*.name.instanceDiffValuesthen writes both entries to the same map key, so one value can overwrite the other. Go map iteration order makes the retained value unstable.The hash must remain hidden, but replacing every hash with the same
*is not required for redaction. Use collision-free opaque labels, or another representation that retains all entries without emitting the SDK hash. Add a fixture where two set blocks have different values for the same nonsensitive field and assert that both values remain visible in the redacted maps.🤖 Prompt for AI Agents

The SDK derives the identifier of a set element from a hash of the element value, so a logged key such as keys.1234 lets a reader test guesses for a low entropy secret even though the value is redacted. Replace the identifier with * for sets that hold a sensitive value, including sets of blocks with a sensitive field. Signed-off-by: Youssef Omar Bouden <youssef.bouden2002@gmail.com>

Description of your changes
The
Diff detecteddebug line logsinstanceDiff.GoString(), the Go syntax of the wholeterraform.InstanceDiff, which is hard to read for resources with many nested attributes.Log the old and the planned attribute values as two flat maps,
oldandnew, keyed by the Terraform attribute path. Keys removed by the plan are absent fromnew, computed values are shown as<computed>, and sensitive values are shown as<sensitive>on both sides. Sensitivity is resolved along the schema path and not only from theSensitiveflag of the diff: the SDK sets that flag infinalizeDiff, which returns early for removed attributes, and the element schemas it builds for lists and sets copy onlyForceNewfrom the parent, so removed secrets and the elements of sensitive collections would otherwise be logged in clear. With the JSON encoder the two objects have sorted keys and can be diffed directly.Fixes #773
