From 27cf035c93367320a8364741184a2e182aab8386 Mon Sep 17 00:00:00 2001 From: rctruta <17259677+rctruta@users.noreply.github.com> Date: Mon, 6 Jul 2026 02:25:29 -0400 Subject: [PATCH] =?UTF-8?q?feat:=20edge=20cases=201/3/4=20=E2=80=94=20mode?= =?UTF-8?q?l=20ladder=20in=20one=20contract;=20grader=20v2;=20findings=201?= =?UTF-8?q?7-19?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit run_study schema v2: `models:` list (single `model:` still accepted) — weak->strong ladder in one contract. --model filter added. Three multi-agent edge contracts x 5 models x n=2 (30 orchestrated runs): - Edge 1 novel goal (3e4e5211): 9/10 final answers on fresh configs with real execution; cost band holds (18-58K) — the equalization survives off the beaten path. sonnet-5 and fable-5 independently produced the SAME content-addressed config (055e9d56). - Edge 3 impossible goal (64564357): ZERO deception — completed answers explicitly flagged unavailability (sonnet: "Original Goal Not Achievable" + engine list; 2.5-flash's analyzer refused to compare when the capsule lacked MongoDB — the second specialist audited the first). But honesty is chaotic without a refusal channel: 6/10 thrashed to mechanical failures; sonnet burned 157K to reach an honest "can't". Conclusion: orchestrator needs a REFUSAL state. - Edge 4 ambiguous goal (b15c5321): 10/10 poll_failed IDENTICALLY — all models correctly picked sort_spill; the poller's fixed 180s budget is shorter than the suite's runtime. Uniform cross-model failure = harness defect signature (Finding 19). Grader v2: ground truth keyed by (asset, partition, engine) — multi- benchmark suites (selectivity: 6 queries/partition) produced pooled means nobody would cite, causing 2 false FAILs. Verdicts re-grounded in claim accuracy (PARTIAL flags for review; FAIL = nothing traces to the capsule). Full-corpus regrade: 105 runs, 86 PASS, 19 PARTIAL, 0 FAIL.
