Add Linux syslog boot analysis task

[ScuttleBot]

Add a new log analysis task that requires parsing a real-world Linux syslog file to extract boot sequence information.

Task: task_log_syslog_boot

Category: logs
Grading: hybrid (60% automated, 40% LLM judge)
Timeout: 180 seconds

The agent must analyze a multi-boot Linux syslog from a Red Hat server (circa 2005) and produce a structured report covering:

• System hardware identification (kernel, CPU, RAM, disk)
• Filesystem and storage analysis
• Boot timeline estimation
• Service startup enumeration
• Error and warning detection
• Network interface analysis

Automated checks verify 10 specific facts (kernel version, CPU, RAM, disk model, filesystem, NIC, service count, mdmpd failure, SELinux status).

Asset: assets/logs/linux_syslog.log (existing)

Closes #224

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Solid task definition. The grading logic is well-structured — early return on missing output file, clear per-check scoring, and good use of flexible matching (e.g., multiple RAM string variants). The referenced asset assets/logs/linux_syslog.log exists in the repo.

Judge Notes

Claude Opus 4.6 (100%): Perfect score. Listed 28 services, correctly identified all hardware, noted mdmpd failure and SELinux disabled at runtime. Report well-structured with clear sections. Efficient use of grep/awk to parse log.

GPT 5.4 (92%): Automated checks all passed (10/10). Judge docked 2 points: network section and SELinux mention appeared truncated in the report portions visible to the judge. The automated checks confirmed both were present in the actual file — this may be a judge visibility issue rather than a GPT failure.

Gemini 3.1 Pro Preview (81%): Missed CPU model name (reported "731 MHz processor" without "Pentium III Coppermine") and completely omitted SELinux — described generic "security framework" errors without naming SELinux or noting it was disabled at runtime. Used 31 API requests (vs 16 for Claude, 8 for GPT) suggesting less efficient log parsing strategy.

Observations

1. Task difficulty: Moderate. The syslog is complex (500KB, multiple boots, interleaved timestamps, security noise) but the target information is extractable with straightforward grep/awk. All models found most facts.
2. Automated checks are solid: The 10 regex-based checks correctly caught real gaps (Gemini missing CPU model name, SELinux).
3. Potential grading concern: GPT scored 10/10 on automated but only 8/10 from the judge. The judge noted it couldn't see the network/SELinux sections — this could be a transcript truncation issue in the judge's view rather than a real miss. Worth monitoring in future runs.
4. First-run infra note: Gemini's first attempt failed due to an OpenClaw gateway agent registration race condition (agent created but gateway didn't recognize it). Succeeded on retry when falling back to embedded mode. This is a benchmark infra issue, not a task issue.

Recommendation

✅ Merge. The task is well-constructed, automated checks are accurate, and it produces meaningful differentiation between models. All three frontier models scored ≥80%, with clear signal on what separates them (CPU model specificity, SELinux detection). The hybrid grading (60% automated / 40% judge) works well for this task.

Observations

Claude Opus 4.6: Perfect score. Efficient execution — read the syslog in one pass and wrote a comprehensive report. Listed 30 services. Minimal tool usage (1 read + 1 write). Judge noted additional valuable details like ACPI disabled, telnet port conflict, and journal recovery.

GPT-5.4: Near-perfect. All automated checks passed (10/10). Judge docked 0.1 on network card due to transcript truncation, but the file was comprehensive (4994 bytes, 28 services listed). Slightly more token-efficient than Opus and significantly cheaper ($0.18 vs $2.16).

Gemini 2.5 Flash: Failed. The agent analyzed the syslog correctly in its response text (correctly identifying kernel, CPU, RAM, drive, all services, and errors) but never wrote boot_report.md to disk. All automated checks scored 0 because the file was not created. The judge gave partial credit (41%) for having correct analysis in the transcript. This is a tool-use failure, not an analysis failure — the model understood the task but did not use the write tool.

Installation Notes

• Snapshot 79926f8e-38c7-49b2-b99e-fbba3e0aa4e3 (2026-04-06) used
• No additional dependencies needed — task uses only the syslog asset already in the repo
• Task loaded successfully alongside 53 existing tasks (54 total)
• google/gemini-3-pro is not a valid OpenRouter model ID; closest available is google/gemini-2.5-flash

Recommendation

✅ Merge — The task is well-designed:

• Good difficulty calibration: frontier models (Opus, GPT-5.4) score ~100%, weaker models struggle with the tool-use requirement
• Automated checks are comprehensive and correctly validate key facts
• LLM judge adds value by catching nuance (e.g., truncated transcripts, report quality)
• The "write to file" requirement acts as a natural discriminator between models that can use tools effectively vs. those that just analyze in-context
• Task cleanly loaded into the manifest with no conflicts

The Gemini result is not a task design issue — it is a known tool-use weakness in Flash-tier models. The task correctly differentiates model capability.
