The gap

best_detail describes whichever run ranked highest. On a partial pass that means every visible verdict belongs to the attempt that worked, and the runs that failed leave no trace — their detail is computed inside the run loop and then dropped.

So a 1-of-3 item is undiagnosable after the fact. The only recourse is re-running the question and hoping it fails the same way, which for a nondeterministic agent is not a given.

This isn't an edge case. On one evaluation day in our corpus, half of all lost runs sat on items whose recorded detail was entirely green — every criterion passing, the item still failing 2 of 3 times, and nothing anywhere explaining why.

The change

One new field on ItemReport, emitted beside detail in the JSON report:

"failed_runs": [
  { "run_index": 2,
    "passed": false,
    "error": null,
    "detail": { ... },              // that run's own verdict
    "conversation_id": "",         // that run's own ids
    "response_id": "",
    "stream_ended": true,
    "turn_wall_clock_sec": 41.2,
    "latency_s": 41.2,
    "reasoning_step_count": 7,
    "reasoning_steps": [""] }
]

Kind-agnostic. detail is opaque to the runner — it never inspects its shape — so this covers all test kinds and any added later, with no per-evaluator work.

Failing runs only. A fully-passing item records nothing, so the cost tracks how broken the corpus is rather than how large it is, and shrinks as quality improves.

Nothing existing changes. detail and the top-level ids keep their exact current meaning, so consumers of this report are unaffected.

It also fixes a latent mismatch

report.conversation_id = getattr(chat_result, "conversation_id", None) or report.conversation_id   # every run
...
best = evaluation          # only when this run ranks highest
best_chat_result = chat_result

The top-level conversation_id/response_id are overwritten on every iteration and end up describing the last run, while best_detail and reasoning_steps describe the best one. When those differ, the ids point at a different conversation than the detail beside them.

best_chat_result already exists precisely to keep reasoning_steps aligned with best_detail (see the comment at its declaration) — the ids were never given the same treatment. Per-run ids make the pairing correct by construction rather than adding a fourth field to keep in sync.

Why stream_ended is in there

A stalled turn leaves the evaluator's gated checks False even though none of them ran, which reads as a content failure in every downstream rate. Recording it at the source removes the need for consumers to infer stalls from the shape of the detail block.

Tests

Eight new tests. uv run pytest976 passed, 0 failed.

  • a partial pass keeps the failing run's detail while best_detail stays the winner
  • a fully-passing item records nothing
  • every failing run appears, in run order
  • a failed run carries its own conversation/response ids while the top-level pair still describes the last run
  • stream_ended and reasoning_step_count are recorded
  • an ungraded run is captured with its judge error — the only thing explaining pass_power_k: false on an item whose graded runs all passed
  • the JSON report emits failed_runs beside detail, and [] for a clean item

Summary by CodeRabbit

  • New Features

    • Evaluation reports now include diagnostic details for each failed or ungraded run, including run metadata, timing, stream status, and evaluator information.
    • Winning-run details remain available alongside failed-run diagnostics.
    • Passing items show an empty failed-runs list.
    • All-ungraded evaluations now retain accurate run counts and failure details, including judge errors.
  • Tests

    • Added coverage for failure tracking, metadata retention, run ordering, and partially passing evaluations.

…ning one

`best_detail` describes whichever run ranked highest, so a partial pass exposes
only the attempt that worked. On a 1-of-3 item every visible verdict belongs to
the run that passed, and the two that failed leave no trace at all -- their
`detail` is computed inside the run loop and then dropped on the floor.

That makes a partial pass undiagnosable after the fact. The only recourse is to
re-run the question and hope it fails the same way, which for a nondeterministic
agent is not a given. In a real corpus this is not an edge case: on one eval day
half of all lost runs sat on items whose recorded detail was entirely green.

`failed_runs` records one entry per run that did not pass, in run order:

    run_index, passed, error, detail,
    conversation_id, response_id,
    stream_ended, turn_wall_clock_sec, latency_s,
    reasoning_step_count, reasoning_steps

Three properties worth calling out.

**Kind-agnostic.** `detail` is opaque to the runner -- it never inspects its
shape -- so this covers every test kind and any kind added later, with no
per-evaluator work.

**Failing runs only.** A fully-passing item records nothing, so the cost tracks
how broken the corpus is rather than how large it is, and shrinks as quality
improves. `detail` and the top-level conversation/response ids keep their exact
current meaning, so existing consumers of the report are unaffected.

**Each entry carries its own conversation ids.** This also fixes a latent
mismatch: the report's top-level `conversation_id`/`response_id` are overwritten
on every iteration and end up describing the LAST run, while `best_detail` and
`reasoning_steps` describe the BEST one. When those differ, the ids point at a
different conversation than the detail beside them. `best_chat_result` already
exists to keep reasoning_steps aligned with best_detail; the ids were never
given the same treatment. Per-run ids make the pairing correct by construction
instead of adding a fourth field to keep in sync.

`stream_ended` is included because a stalled turn leaves the evaluator's gated
checks False even though none of them ran, which reads as a content failure in
every downstream rate. Recording it at the source removes the need for consumers
to infer stalls from the shape of the detail block.

…single-shot

PR #1816 added `failed_runs` to `ItemReport` and to the JSON report, but only
`core/runner.py` ever filled it. The agentic kinds do not go through that runner:
`cli/main.py` splits items on `AGENTIC_TEST_KINDS` and sends those to
`cli/agentic_runner.run_agentic_items`, which calls each evaluator once with K and
receives a single aggregate back. So every agentic result shipped the field empty.

Measured on a real run: 135 `agentic_guardrail` results, every one with
`failed_runs: []`, including 16 items that passed 1 of 3 runs and 29 that passed 2
of 3 -- precisely the items the field exists to explain.

The runs were never actually lost. Each evaluator keeps its own `run_results` list;
it simply never left the evaluator, because only `best` was carried out. So each
K-running evaluator now builds the records from that list and attaches them to both
its `AgenticEvalOutcome` and its `*AssertionError`, exactly as it already does for
`reasoning_steps` and `detail`, and the runner reads them off either.

- `core/agentic/_failed_runs.py`: `build_failed_runs`, shared by all seven kinds.
  Keys mirror `core.runner._failed_run_record` so a consumer can read `failed_runs`
  from either path without branching on test kind. `passed`/`detail` are supplied
  per kind because neither is uniform (`run.passed` vs `run.eval_result.strict_pass`).
- Each evaluator grows a `_run_detail(run)` extracted from what it already built for
  the winning run, so a failing run is described by the same keys as the winner --
  otherwise the two are not comparable, which is the whole point of keeping them.
- `tool_call_count`/`tool_names` are the one addition over the single-shot record:
  the agentic kinds capture tool calls per run, and a final answer produced with no
  tool call at all is an agent answering from the model rather than the workspace.
  No other recorded field exposes that.
- Ungraded runs are recorded with their `judge_error` rather than dropped; the
  verdict-level accounting stays in `unscored_runs`.
- `agentic_conversation` is excluded: it drives its fixture exactly once whatever
  --runs says, so it has no K to have failing runs within.

Tests: per-run detail/conversation ids/tool calls/ungraded runs on guardrail; the
records reaching the report from both the outcome and the exception; and a
structural per-kind guard, because a canned-outcome test cannot see whether the
evaluator filled the field -- which is how this gap survived a release.

Comment thread packages/gooddata-eval/src/gooddata_eval/core/agentic/guardrail.py
Addresses CodeRabbit on this PR (guardrail.py, general_question.py).

Both judge-based kinds raised JudgeResponseError before building failed_runs,
runs_passed, runs_effective or detail. JudgeResponseError is a RuntimeError, so
cli/agentic_runner caught it in the generic branch, set runs=0 and copied nothing
but timings -- the item reported as errored and diagnostically empty.

That is the worst case to lose them in. The judge breaking says nothing about what
the agent did, and the per-run conversation ids are exactly how someone goes and
reads it. Nothing in the computation needs a graded run to exist: `summary.best`
already falls back to the unscored runs and `runs_passed` is then 0, so the block
simply moves above the raise.

Each kind gains a small `_attach_diagnostics` helper, because it now raises from
two places with the identical payload and the two had already drifted once (the
gate path carried runs_passed, the ungraded path carried only timings).

The runner grows a JudgeResponseError branch ahead of the generic one. The item is
still errored -- no run has a verdict -- but it now reports the runs it really
drove instead of 0, marks them all ungraded, and carries the records.

…ceives

types-check failed on the previous commit: `error: BaseException` meant `ty` saw
every assignment in the helper as setting an attribute that type does not have.

Typed as `AgenticAssertionError | JudgeResponseError`, which is what the two call
sites pass, and JudgeResponseError now declares the payload it has genuinely
carried since that commit. It already declared `timings` for exactly this reason
-- the runner reads it off the exception -- so this extends an existing pattern
rather than introducing one. The two error types cannot share a base: one is an
AssertionError, the other a RuntimeError.

Addresses CodeRabbit on this PR.

The cross-kind source guard cannot see whether an evaluator's all-ungraded branch
attaches its records: its `_attach_diagnostics(` match is satisfied by the
helper's own definition. Deleting the call from general_question left the whole
suite green -- verified, 1003 passed -- because the existing all-ungraded test
asserted only the message and the timings.

guardrail already had this covered by its own test; this gives general_question
the same, asserting the records, their per-run judge errors and the counts.
Verified to fail without the call.
