Commands: timeout 600 vp i (each checkout); background vp run dev; Playwright 1.60 with /usr/bin/google-chrome.
Main web/server ports: 8693/16733. Main stopped before PR startup.
PR web/server ports: 5733/13773; explicit isolated --home-dir /home/user/t3code/.t3.
Real ACP Registry codex-acp 2.5.0, CODEX_PATH=/home/user/.local/bin/codex, local proxy, gpt-6.1-sol. Project/provider/threads/prompts created through UI. No mocks or fixture turns.

Observer: NODE_OPTIONS --import=/tmp/acp-observer.mjs wraps TextDecoder.decode and records only source callsite and byteLength when stack includes effect-acp/src/protocol.ts. It delegates unchanged to original decoder. No payload content captured.
main: {"172":{"calls":28,"bytes":35620},"711":{"calls":16,"bytes":20735}}
pr: {"172":{"calls":40,"bytes":65560}}
line 172 = actual parser decode; line 711 = redundant raw diagnostic decode. Main observed 16 raw calls; PR observed zero. Totals include startup discovery and turn/session lifecycle; these are not normalized throughput or latency measurements.

Persisted real runs:
{"provider":"acpRegistry_codex_acp_verify","status":"completed","model":"gpt-6.1-sol"}
{"provider":"acpRegistry_codex_acp_verify","status":"completed","model":"gpt-6.1-sol"}

One ACP run above was created on main and copied with stopped state to PR. PR resumed it, then completed a fresh ACP thread and follow-up; normal Codex completed a neighboring turn.
