chore(eval): put the evaluation harness, ledger and current results in the repo - #116

Conversation
…n the repo The evaluation rounds produced real findings (#67/#68/#69/#72/#81/#115 ...) but the harness and the numbers lived outside the repo: `jobs/` is gitignored and the reports were uncommitted, so a fresh checkout could neither reproduce a number nor see the trend. What lands here: - `scripts/eval/` — the L1 harness: 25 suites (`sweep.sh`), the mock provider with its fault-injection modes, the JSONL/ACP/trust/workflow/recovery probes, plus `summarize.py`, which turns a Harbor run into the committed per-task summary. New in this round: `workspace_lifetime_probe.py` (the #115 contract) and the `FILIFETIME=/FICMD64=` mock arguments it needs. - `docs/reports/evaluation-ledger.{md,json}` — one row per round with the protocol that makes the numbers comparable (source, harness, model, attempts/concurrency, task set) and the findings that left a permanent test behind. - `docs/reports/2026-09-19-v0.4.32-evaluation.md` + `…-tb2-v0432-summary.json` — the current round: L1 24/24 green, TB2 mean 0.7955 (70/88), and the two issues it filed (#114 argv self-kill, #115 workspace-lifetime service). Raw trajectories and container logs stay out of git (GBs, workspace content); the summary JSON carries one row per task (reward, exception, agent exit, turns, bytes).

Inline comments:
In `@docs/reports/evaluation-ledger.json`:
- Line 54: Update the L1 suite count in the evaluation ledger and the 2026-09-19
report to match the 26 entries executed by scripts/eval/sweep.sh, including both
sandbox_probe.py modes; alternatively, document the two entries added after that
run.
In `@scripts/eval/exit_code_probe.py`:
- Around line 158-160: Update the skipped branch in the probe’s record flow so
the absent musl binary is reported as a distinct informational or excluded
outcome rather than passing `ok=True`; ensure the exit-code-3 contract is
counted as passing only when the sandboxed action is actually exercised, while
preserving the existing skip message.
In `@scripts/eval/fault_injection.py`:
- Around line 305-309: Update the usage lookup in the reporting block to read
the provider_usage field populated by parse_events instead of usage, preserving
the existing fallback and token formatting so input and output token counts are
displayed.
In `@scripts/eval/repo_task.py`:
- Line 690: Update the result artifact lookup in effective_fail_to_pass() to use
the same ten-character SHA prefix that run() uses when writing result
directories. Apply the matching prefix truncation in l3_batch.sh’s
latest_result() lookup so baseline artifacts are found and agent trials proceed.
In `@scripts/eval/sandbox_enforcement_probe.py`:
- Line 94: Update the _mentions_trust assignment to parenthesize the
warning-detection expression and require “trust” to appear with the expected
warning text, rather than allowing any standalone occurrence in lowered.
Preserve the existing detail field and narrow the match to the intended warning
output.
In `@scripts/eval/summarize.py`:
- Around line 144-147: Correct the metric note in the summary construction
around the “note” field so it states that mean_reward uses every scheduled
trial, with unrewarded trials counted as 0, while mean_reward_scored_only
averages only trials that produced a verifier reward. Ensure the corrected note
is propagated to committed summaries generated from this source.
In `@scripts/eval/triage.py`:
- Around line 127-128: Guard the scored-accuracy calculation in the report
generator using len(scored), emitting a placeholder when no trials were scored
while preserving the existing calculation otherwise. Apply this change at
scripts/eval/triage.py lines 127-128 and scripts/eval/milestone_report.py lines
113-114, covering each report’s len(passed) / len(scored) term.

Use the truncated SHA prefix for both result lookups.
run() writes artifacts under {sha[:10]}-{stamp}, but effective_fail_to_pass() searches for {sha}-*/result.json. For a full commit SHA, it loads no baseline result, so fail-to-pass --count returns 0. l3_batch.sh has the same mismatch in latest_result(). It cannot find the artifact after the baseline-only run, reports baseline run failed, and does not start agent trials.

Why
The evaluation rounds produced real product findings (#67, #68, #69, #72, #81, #115 …), but the
things that produced them lived outside the repository:
jobs/is gitignored, the probe harnesswas never committed, and the reports were uncommitted files on one machine. A fresh checkout could
neither reproduce a number nor see the trend, and nothing stopped a fixed defect from silently
regressing.
This PR puts the reusable half in the repo and deliberately leaves the raw half out.
