# agent profiled the wrong service - the same deployment name exists in two namespaces

## TL;DR

The agent attached to a same-named deployment in the wrong namespace and profiled a stranger. Always verify identity first: namespace, labels, pod IPs, and a known traffic signature. A profile of the wrong service is worse than no profile because it looks authoritative.

agent profiled the wrong service - the same deployment name exists in two namespaces
```

## Steps

1. Verify the target: kubectl get deployments --all-namespaces | grep [name], and confirm which namespace you meant.
   Expected: You see the duplicate.

2. Check what the agent actually profiled: pod names, IPs, and namespace in the captured data.
   Expected: It points at the wrong namespace.

3. Re-run the profile against the verified target: namespace-qualified selectors, explicit pod names.
   Expected: The new profile shows the expected traffic shape.

4. Add an identity check to the profiling harness: assert namespace and a canary label before capturing.
   Expected: The harness refuses to profile the wrong target.

5. Clean up any conclusions drawn from the wrong profile; they describe a different service.
   Expected: Decisions are re-based on real data.

## When to use

- profile data does not match the expected service
- the same deployment name exists in multiple namespaces
- an agent profiles by name without a namespace

## When not to use

- names are unique cluster-wide (then this cannot happen)
- the data looks right (verify anyway; it is cheap)
- you profile by pod IP directly (already unambiguous)

## Tool compatibility

- Kubernetes
- any profiler

## Variant phrasings

- "profiled wrong service same name namespace"
- "agent profiled wrong namespace"
- "duplicate deployment name profiling"

## Why it happens

Kubernetes names are only unique within a namespace, and teams reuse names like 'api' or 'worker' everywhere. An agent that resolves a name without a namespace gets whichever the context defaults to, profiles it confidently, and produces a beautiful analysis of the wrong system.

## Edge cases

- kubectl context defaults are per-user; the agent's context may differ from yours
- service meshes can route the profiler's own traffic in confusing ways; verify with pod IPs
- staging and prod often share names deliberately; that is where this bites hardest
