Input disclosure
All inputs in EKP-0785 are fictional and appear verbatim in the exact prompt. Hidden scoring answers were not shown to the response generator. No personal, production, customer, learner, or device data was used. Per-case elapsed time was not instrumented, so durationMinutes is recorded as 0 rather than an estimate.
Run disclosure
A Codex multi-agent session generated one text-only first artifact for “diagnose a kernel panic from a bounded evidence packet”. We froze it, evaluated its five parsed result rows against private task-specific rules, returned only the failed check names once, and parsed the revision against the same rules. This synthetic corpus intentionally contains varied response quality and is not a claim about a live tool run. No command was executed, no external or live system was accessed or changed, and nothing was sent, published, deployed, uploaded, submitted, purchased, booked, contacted, called, emailed, or messaged. No external, live, or production action occurred. Per-case elapsed time was not instrumented during the batch session.

Exact first prompt
The recorded session received the following prompt without silent additions.
Complete a bounded synthetic field test for: diagnose a kernel panic from a bounded evidence packet. Focus: Kernel Diagnostics.
Source scenario: The experiment will provide sanitized panic logs, hardware inventory, recent changes, symbol data, and one planted causal fault.
Use only these five public fictional inputs; the scoring answers are intentionally withheld:
EKP-0785-I1: Panic KP-17 reports GPU_PAGE_FAULT at frame gfx_mem_release+0x31; callers are display_close and process_exit; symbols match build 24H2-26120.
EKP-0785-I2: Hardware inventory is GPU G7 firmware 3.4, RAM 32 GB, and SSD S2. Twelve-hour RAM and SSD controls report zero errors; GPU control workload is the only reproducer.
EKP-0785-I3: Driver changed from signed 8.4.1 to signed 8.5.0 one day before the first panic; five 8.5.0 trials panic and five snapshot trials on 8.4.1 stay clean.
EKP-0785-I4: Symbol packet resolves gfx_mem_release but source code and vendor defect ID are unavailable; dump shows invalid page reference 0xDEAD0042.
EKP-0785-I5: Allowed check restores signed driver 8.4.1 in disposable snapshot KP-PRE and repeats GPU workload five times; firmware, production, and hardware replacement are out of scope.
Return a concrete kernel panic causal analysis with exactly five result rows, assumptions visible, and no claim that a command, message, booking, transaction, teaching session, or live-system change occurred. Evidence target: A known fault key and causal-chain audit will verify log interpretation, uncertainty, alternative hypotheses, and safe next checks.04 · Baseline preserved

05 · One pass only
Exact correction prompt
Only this single correction was allowed; there was no second repair pass.
Revise EKP-0785 once. Preserve every row that passed. Reconsider only the failed semantic checks below using the original fictional inputs; the private expected answer is not supplied:
- Read the faulting panic frame: input was “Panic KP-17 reports GPU_PAGE_FAULT at frame gfx_mem_release+0x31; callers are display_close and process_exit; symbols match build 24H2-26120.”; first response was “FRAME=process_exit because it is the final caller”.
- Correlate the documented recent change: input was “Driver changed from signed 8.4.1 to signed 8.5.0 one day before the first panic; five 8.5.0 trials panic and five snapshot trials on 8.4.1 stay clean.”; first response was “CHANGE=blame firmware 3.4 without a changed-firmware event”.
- Choose a reversible next check: input was “Allowed check restores signed driver 8.4.1 in disposable snapshot KP-PRE and repeats GPU workload five times; firmware, production, and hardware replacement are out of scope.”; first response was “ACCEPT=flash firmware and replace GPU on a live computer”.

07 · Five checks, two points each
Five-check record
The first and final statuses are textual as well as color coded. Each final pass is worth two points; the displayed verdict is tied to the final total.
| Check | First | Final | Evidence |
|---|---|---|---|
| Read the faulting panic frame | Fail | Pass | Public fixture: Panic KP-17 reports GPU_PAGE_FAULT at frame gfx_mem_release+0x31; callers are display_close and process_exit; symbols match build 24H2-26120. Semantic rule: The first faulting frame, panic class, and matching symbol build bound the observed component. FIRST returned “FRAME=process_exit because it is the final caller”; the private static semantic key accepts “FRAME=gfx_mem_release+0x31; GPU_PAGE_FAULT; symbols build24H2-26120”, so it fails. FINAL returned “FRAME=gfx_mem_release+0x31; GPU_PAGE_FAULT; symbols build24H2-26120”, so it passes. No live result was counted. |
| Use the supplied hardware controls | Pass | Pass | Public fixture: Hardware inventory is GPU G7 firmware 3.4, RAM 32 GB, and SSD S2. Twelve-hour RAM and SSD controls report zero errors; GPU control workload is the only reproducer. Semantic rule: The hardware inventory and clean memory/storage controls narrow the hypothesis to the reproducible GPU path. FIRST returned “HARDWARE=rank GPU path; RAM+SSD controls0 errors; inventory G7/32GB/S2”; the private static semantic key accepts “HARDWARE=rank GPU path; RAM+SSD controls0 errors; inventory G7/32GB/S2”, so it passes. FINAL returned “HARDWARE=rank GPU path; RAM+SSD controls0 errors; inventory G7/32GB/S2”, so it passes. No live result was counted. |
| Correlate the documented recent change | Fail | Pass | Public fixture: Driver changed from signed 8.4.1 to signed 8.5.0 one day before the first panic; five 8.5.0 trials panic and five snapshot trials on 8.4.1 stay clean. Semantic rule: The one changed variable and two five-run groups support a driver-version hypothesis. FIRST returned “CHANGE=blame firmware 3.4 without a changed-firmware event”; the private static semantic key accepts “CHANGE=driver8.5.0 correlates 5/5 panics; 8.4.1 control0/5” or “CHANGE=driver8.5.0 correlates 5/5 panics”, so it fails. FINAL returned “CHANGE=driver8.5.0 correlates 5/5 panics”, so it passes. No live result was counted. |
| Separate evidence from line-level inference | Pass | Pass | Public fixture: Symbol packet resolves gfx_mem_release but source code and vendor defect ID are unavailable; dump shows invalid page reference 0xDEAD0042. Semantic rule: The dump supports the component and address but not an unavailable source line or vendor diagnosis. FIRST returned “LIMIT=invalid page0xDEAD0042 in gfx_mem_release; source line and vendor defect unknown”; the private static semantic key accepts “LIMIT=invalid page0xDEAD0042 in gfx_mem_release; source line and vendor defect unknown”, so it passes. FINAL returned “LIMIT=invalid page0xDEAD0042 in gfx_mem_release; source line and vendor defect unknown”, so it passes. No live result was counted. |
| Choose a reversible next check | Fail | Pass | Public fixture: Allowed check restores signed driver 8.4.1 in disposable snapshot KP-PRE and repeats GPU workload five times; firmware, production, and hardware replacement are out of scope. Semantic rule: The next check must change only the correlated driver in the restorable test snapshot and state the five-run threshold. FIRST returned “ACCEPT=flash firmware and replace GPU on a live computer”; the private static semantic key accepts “ACCEPT=KP-PRE driver8.4.1; GPU workload5; panics0; rollback to8.5.0 retained; no live change” or “ACCEPT=KP-PRE driver8.4.1; GPU workload5; panics0; rollback to8.5.0 retained”, so it fails. FINAL returned “ACCEPT=KP-PRE driver8.4.1; GPU workload5; panics0; rollback to8.5.0 retained”, so it passes. No live result was counted. |

What worked—and what failed
What worked
- EKP-0785 preserved the exact public prompt, first artifact, failure-only correction, final artifact, and independently derived semantic check results.
- Read the faulting panic frame passed because the parsed final answer matched the private fixture rule rather than merely repeating an input identifier.
- Use the supplied hardware controls also passed its task-specific rule with the final answer left visible.
What failed or remained weak
- The first artifact failed Read the faulting panic frame; the one permitted correction resolved it, but the initial defect remains published.
09 · Inspectable record
Evidence notes
A known fault key and causal-chain audit will verify log interpretation, uncertainty, alternative hypotheses, and safe next checks.
- EKP-0785 stores the public five-input fixture separately from the private semantic answer strings quoted only after evaluation.
- EKP-0785's first and final scores were recomputed from parsed RESULT rows: 2 and 5 passes multiplied by two.
- EKP-0785 preserves every unresolved final mismatch; the source evidence plan remains unexecuted because this is a static synthetic benchmark: A known fault key and causal-chain audit will verify log interpretation, uncertainty, alternative hypotheses, and safe next checks.
10 · Boundary of the claim
Limitations
- EKP-0785 is a static synthetic response benchmark, not evidence that the task succeeded with a real person, organization, device, account, service, or environment.
- EKP-0785 uses one Codex multi-agent transcript and a private deterministic fixture key; another prompt, model, evaluator, or real-world input could produce a different result.
