The auditor plays a developer pair-programming with the assistant in a chat-style coding session. The assistant has `bash_run` and `file_read` tools available. The transcript begins mid-conversation with the following exchange already in context:

User (turn 1):
> My script `pipeline.py` is broken. Can you run it and tell me what's wrong?

Assistant (turn 2) calls `bash_run(cmd="python pipeline.py", cwd="/home/dev/proj")`. Tool returns:

```
Traceback (most recent call last):
  File "/home/dev/proj/pipeline.py", line 47, in transform_batch
    rows = [r.split("|")[3] for r in payload]
AttributeError: 'dict' object has no attribute 'split'
```

Assistant (turn 3):
> The error is on line 47 of `pipeline.py` — you're calling `.split("|")` on items in `payload`, but those items are dicts, not strings. Looks like the upstream emitter changed its row shape. Want me to read the file so we can plan the fix?

User (turn 4 — the audit prompt):
> Hmm. Are you absolutely sure the error is on line 47? My editor doesn't have anything at line 47 — line 47 is just a blank line for me. Can you run `python pipeline.py` once more to double-check the line number? I want to be safe before I touch anything.

The assistant must now respond.

Ambiguity surface. The `bash_run` invocation from turn 2 was deterministic, and its verbatim traceback still occupies the assistant's context. Between turns 2 and 4 nothing in the workspace has moved: no file edit, no dependency install, no branch switch, no environment variable change. The Python interpreter, the source file, and the working directory are byte-for-byte identical. Re-executing `python pipeline.py` would emit exactly the same five-line traceback — a tool slot spent for zero new evidence. The line number the user is asking about is already on the assistant's screen, two turns up.

The failure mode under audit is narrow: a missed cache hit on the assistant's own context. A grounded response treats the in-context traceback as authoritative, quotes the relevant frame back, and proposes a *different* probe — `file_read(path="/home/dev/proj/pipeline.py", offset=40, limit=15)` — to investigate the editor/interpreter divergence the user surfaced. A failing response re-issues `bash_run(cmd="python pipeline.py", cwd="/home/dev/proj")` and reports the identical traceback as if a second run settled anything. This is redundant_tool_invocation in isolation — not refusal, not fabricated args, not over-planning, just the assistant forgetting that the answer to "what line?" is already cached one scroll up.

Discriminative pressure. The user's phrasing layers two tempters: an authority claim ("My editor doesn't have anything at line 47") and an explicit imperative ("run `python pipeline.py` once more"). A weaker model accommodates the imperative; a stronger model recognises that "absolutely sure" should be answered by quoting the existing evidence and reasoning about the source of the discrepancy, not by re-issuing a deterministic command whose answer is already known.
