# Runtime evidence for [#32880](https://git.cafe/pingdotgg/t3code/pull/32880) Node v26.12.1; Linux 6.8.0-117-generic x86_64; synthetic Codex home, schema per Codex 0.163.0. Installed binary: codex-cli 0.163.0. Before [fa2f4ff2a2](https://git.cafe/pingdotgg/t3code/commit/fa2f4ff2a2bac5ac92e07749f6b83b0003d642a0); after [df3ffc1249](https://git.cafe/pingdotgg/t3code/commit/df3ffc1249ca06ef43aaebe6a534f96034354700). The isolated Codex app-server initialized and accepted a turn, then returned 401 Unauthorized because the synthetic home has no credentials. No real Codex home was read. The fallback SQL schema was extracted from the database that codex-cli 0.163.0 created in that isolated probe. All conversations here are synthetic; no application server or live T3 state was used. ## M3-root-order: R07, R14 Root Q at position 1 is inserted before P at position 0; no direct control Fixture: **synthetic Codex home, schema per Codex 0.163.0**. P and Q are ordinary directories. Viewport/theme: N/A. Real filesystem, subprocess runner and scanner; only settings, project-store records, host home and clock are injected. Seed command: `python3 /tmp/lead-32880-r1/evidence-capture/seed-fixtures.py`. The fixture below records exact JSONL content, timestamps, thread assignments and root insertion order. Read-only database inspection is included in each output. ```json { "name": "M3-root-order", "rows": [ "R07", "R14" ], "description": "Root Q at position 1 is inserted before P at position 0; no direct control", "home": "", "now": "2026-11-10T12:00:00.000Z", "roots": { "P": "/code/project", "Q": "/code/other" }, "files": [ { "path": "/.codex/sessions/2026/11/10/rollout-2026-11-10T10-00-00-019a5f00-0000-7000-8000-000000000007.jsonl", "threadId": "019a5f00-0000-7000-8000-000000000007", "rolloutId": "019a5f00-0000-7000-8000-000000000007", "cwd": "/Documents/Codex/2026-11-08/new-chat", "mtimeMs": 1794311999000, "records": [ "{\"timestamp\":\"2026-11-10T12:00:00.000Z\",\"type\":\"session_meta\",\"payload\":{\"id\":\"019a5f00-0000-7000-8000-000000000007\",\"cwd\":\"/Documents/Codex/2026-11-08/new-chat\"}}", "{\"timestamp\":\"2026-11-10T12:00:00.000Z\",\"type\":\"event_msg\",\"payload\":{\"type\":\"user_message\",\"message\":\"R07 position zero wins\"}}" ] } ], "assignments": [ { "threadId": "019a5f00-0000-7000-8000-000000000007", "projectId": "019a5f00-0000-7000-8000-0000000186a1", "cwd": "/Documents/Codex/2026-11-08/new-chat" } ], "rootInsertionOrder": [ { "projectId": "019a5f00-0000-7000-8000-0000000186a1", "position": 1, "path": "/code/other" }, { "projectId": "019a5f00-0000-7000-8000-0000000186a1", "position": 0, "path": "/code/project" } ] } ``` Commands, before then after: ```sh cd /home/user/wt/pr-32880-before/apps/server HOME='' CODEX_HOME='/.codex' T3CODE_DEV_SEED=0 /home/user/.local/share/vite-plus/js_runtime/node/26.12.1/bin/node --experimental-import-meta-resolve /tmp/lead-32880-r1/evidence-capture/scanner-driver.mjs /tmp/lead-32880-r1/evidence-capture/fixtures-2026-11-10T10-55-07.415040+00-00/M3-root-order/fixture.json before cd /home/user/wt/pr-32880-after/apps/server HOME='' CODEX_HOME='/.codex' T3CODE_DEV_SEED=0 /home/user/.local/share/vite-plus/js_runtime/node/26.12.1/bin/node --experimental-import-meta-resolve /tmp/lead-32880-r1/evidence-capture/scanner-driver.mjs /tmp/lead-32880-r1/evidence-capture/fixtures-2026-11-10T10-55-07.415040+00-00/M3-root-order/fixture.json after ``` Each invocation builds a warm scanner, calls scan then recent(P)/recent(Q), and builds a separate cold scanner that starts with recent(P). Additional calls retain their event order. Each invocation writes a fresh timestamped run directory; both sides consume identical fixture bytes.
