Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 🧰 Additional context used📚 Code guidelines (1)📝 WalkthroughWalkthroughThe admission webhook now looks up original values by JSON Pointer path and logs mutation patch details before returning its response. An additional patch-logging loop at package scope makes the Go file syntactically invalid. ChangesWebhook Mutation Logging
Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~10 minutes Change: Feature Suggested labels: Merge Risk: 🟠 High · up to The webhook source file does not compile, so the scheduler package, including the admission webhook, cannot be built or deployed as submitted. Removing the stray loop that follows the logging helper should restore the build. The intended per-field before-and-after logging is otherwise present. This change is not ready to merge until the build is fixed. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The intended logging exposes original and replacement field values without sensitivity filtering. Logging only mutated paths limits disclosure, but does not guarantee that their values are nonsensitive. No unauthorized disclosure is verified, and a syntax error currently prevents this revision from running. Retained concerns

Log mutation metadata without raw patch values. When a tenant puts confidential data in a valid container name, the Iluvatar mutator copies that name into SOL_CONTINER_NAME. The INFO log then exposes the patch value to log readers. Log only the operation and path.

Include the original field value.
patch.Value supplies the operation value, not the original field value. The linked issue requires both before and after values. Read the prior value from req.Object.Raw and log it as before.

Remove the package-scope patch loop.
logMutationPatches closes at Line 271. The second for loop starts outside any function, so Go cannot compile pkg/scheduler/webhook.go. Remove Lines 272-283; the loop inside logMutationPatches already logs the patches.

What type of PR is this?
/kind feature
What this PR does / why we need it:
This PR adds structured mutation logging to HAMi's admission webhook.
Currently, the webhook silently mutates Pods (e.g., changing
schedulerName, injecting GPU annotations, updating resource limits) and only logs the finalallow/denyoutcome. When a user submits a Pod and it behaves unexpectedly, there is no built-in way to know what HAMi changed without manually diffing the specs.This PR captures the JSON Patch operations automatically computed by
admission.PatchResponseFromRawand emits a structuredklog.InfoSline for every changed field, answering the question: "What did HAMi change in my Pod, and why?"Example output:
This is Phase 1 of the Webhook Observability feature (structured logging). No full Pod specs are stored or logged to avoid exposing sensitive data, only the specific paths that were mutated.
Which issue(s) this PR fixes:
#3163
Special notes for your reviewer:
The diff patch is already computed for free on line 138 (
admission.PatchResponseFromRaw), so we just capture that response array and loop over it. No new JSON-diffing dependencies were required, keeping this extremely lightweight and zero-risk.Does this PR introduce a user-facing change?:
