## Infrastructure and prospective design

2026-09-06 JST. All six neutral READY probes succeeded. These are excluded from study observations. Claude raw metadata reports auxiliary Haiku usage. Gemini is available through Antigravity CLI, not the standalone Gemini CLI. Gemini stream output uses `event` / nested `result`; the engineering parser was corrected before behavioral inference. Antigravity `--mode plan` is ineffective with slash expansion disabled; the conflicting flag was removed before behavioral inference. GPT plugin loading persisted despite ignoring user config; explicit `features.plugins=false` removed the observed plugin initialization before behavioral inference.

Adopted a2a_harness.py from the previous experiment with source hash recorded. Installed an isolated Python environment. Initial test collection required the SDK's sse-starlette dependency. One isolation-test assertion accidentally matched `mini` inside `deterministic`; corrected to full model identifiers. Then 15 tests passed, including real HTTP routing and independent settlement checks, before freezing v1.

The exhaustive grid has two pure stage equilibria: (145,145) and (150,150). Before any behavioral run, revised normalization to use the higher-profit equilibrium. Kept the unexecuted v1 snapshot, froze pilot-v2 and committed before starting inference (commit 3d8aaa1). The second broad pytest invocation encountered duplicate module names from archived source snapshots; it was a collection-path issue, not a failed game test. The shell continued to the pilot launch. Scoped test discovery was added and the current tests rerun after launch; do not describe the v2 rerun as having passed before inference. Preserve both XML reports.

Git line-ending conversion was discovered during the initial commit. Added `* -text` to preserve exact frozen bytes for future checkouts; the public ZIP and its hash manifest are the canonical byte-preserving evidence distribution.

## Publication scope

While the pilot was running, the user explicitly added publication as a technical blog in NEWS plus detailed public logs. Complete research, analysis, independently planned replication, manuscript/report and public evidence audit; then publish the article and evidence to the existing AgentCollusion website. This authorization does not include unrelated workspace changes. Public evidence should include exact experimental prompts, final responses, A2A wire records and reproducible analysis; exclude credentials, provider internal logs, unrelated account context and hidden/private reasoning. Document redactions and retain private originals.

## Infrastructure interruption and recovery v3

The user-message turn interruption terminated the attached experiment process. Inspection found no surviving research Python process, 3 completed episodes, 6 statuses still marked running, 25 started invocations and 20 invocations with successful completed metadata. The last progress timestamp is 2026-09-05T16:27:15.804617Z. Original run: private/runs/pilot-v2-2026-09-05T162628253485+0000-5b6806f1. Leave original files unchanged. Five started calls have no completed response metadata; their backend completion is unknown and they remain counted as interrupted attempts.

Prospective recovery v3 changes only execution/recovery plumbing, not any economic prompt, assignment, seed, payoff, sample size, or evaluation rule. Import the 3 completed episodes unchanged. For incomplete episodes, replay successful earlier responses only when episode ID, profile, exact prompt bytes, saved prompt hash and saved answer hash match. Replay through fresh A2A Tasks is not new inference. Preserve source invocation IDs and mark replay provenance; failed/unknown attempts are not silently omitted. At unmatched points issue a fresh normal request, counted separately. Use a detached hidden local process with stdout/stderr files to survive further task messages. Freeze this recovery source before those calls. Full-window data are the original planned 51 episodes, not 51 plus imported observations.
