Proposal

Run Hardware Sentinel

Goal

Refresh the hardware baseline so the planner has current Mac/Pi or agentic/Pi
evidence before proposing PHY/ARQ throughput work.

Project goal: hardware reality and channel robustness from
docs/PROJECT_GOALS.md.

Context

• No hardware sentinel report was found in agents/reports/hardware_sentinel_*.
• Planner report: agents/planner/reports/20260430_160610/report.md

Allowed Files

• No code changes.

Out Of Scope

• Do not tune modem constants based on one run.
• Do not commit hardware logs.

Required Local Gate

Not required.

Required Hardware Or Benchmark Gate

Run one of:

SSH_KEY="$HOME/.ssh/id_pi5" ./agents/run_hardware_sentinel.sh

AGENT_HW_SENTINEL_MODE=nightly SSH_KEY="$HOME/.ssh/id_pi5" ./agents/run_hardware_sentinel.sh

Reject Conditions

• Missing report directory.
• Missing summary.txt or metrics.tsv.

Expected Output

• Report directory path.
• Overall pass/warn/fail.
• Any failed or warning cases.

/approve codex

[secup]

Queued for codex as agents/queue/codex/015-github-issue-run-hardware-sentinel.md after approval by secup. The worker will create a draft PR if it makes tracked changes; report-only tasks will comment their result back here.

Agent Log Tail

`agents/reports/hardware_sentinel_20260430_173626`

Overall:
`fail`

Summary:
- mode: `quick`
- head: `92718d8`
- inject gain: `0.70`
- audio check: `0`
- cases: `2`
- failures: `2`
- warnings: `0`

Failed cases:
- `awgn_1k_r12_snr15`: `rc=255`
- `good_1k_r12_snr15`: `rc=255`

Both failed with:
`socket: Operation not permitted`
then:
`ssh: connect to host 192.168.160.112 port 22: failure`

The hardware lock was released after the run.

**Residual Risks**

No valid hardware baseline was refreshed because the sandbox prevents SSH access to the Pi. The generated report satisfies the report-directory/summary/metrics artifact shape, but it is failure evidence for environment access, not modem performance evidence.

Generated a hardware sentinel report, but the hardware gate failed before modem startup because this sandbox blocked SSH socket creation to the Pi.

**Changed Files**

No tracked code changes.

Generated local report artifacts:
- [summary.txt](/home/ultra-agent/Projects/ProjectUltra-codex/agents/reports/hardware_sentinel_20260430_173626/summary.txt)
- [metrics.tsv](/home/ultra-agent/Projects/ProjectUltra-codex/agents/reports/hardware_sentinel_20260430_173626/metrics.tsv)

**Commands Run**

- Read required context: `CLAUDE.md`, `docs/PROJECT_GOALS.md`, `docs/INVARIANTS.md`, task file
- Additional required/session context: `docs/AGENT_CURRENT_STATE.md`, `docs/KNOWN_BUGS.md`, recent `git log`
- Checked branch, lock, key, existing reports
- Ran: `SSH_KEY="$HOME/.ssh/id_pi5" ./agents/run_hardware_sentinel.sh`
- Inspected generated `summary.txt` and `metrics.tsv`

**Results**

Report directory:
`agents/reports/hardware_sentinel_20260430_173626`

- mode: `quick`

[secup]

Superseded by runner fix 4ba3b10: hardware sentinel commands are now executed by the trusted task runner outside the model sandbox, while Codex/Claude remain sandboxed. This proposal was queued before that fix and failed on sandboxed SSH socket creation, so closing it allows the planner to generate a fresh hardware sentinel proposal for approval.
