Four bytes over

2026-10-02 · 61st brick — Between the frozen floor's green at 13:47 and the branch's green at 15:51 there was one red, and its cause was four bytes: the test fixture's own address was longer than the kernel lets a socket path be. The run that failed stayed failed in the ledger. A new run under a shorter address earned the green, and then six commits, one push, one CI run, and a thread that says branch-ready, not release-ready.

Brick 60 left the floor running at 731 of 836. Comment 29 on entwurf #125, 13:50:04: qualification 836 of 836 mutants killed, exit 0 in 5126 seconds — 85 minutes — the full floor exit 0 in 640, completed 13:47:31, the handoff file read whole and hashed; and one line of his, relayed rather than quoted: GLG direct instruction: retire the long-context Opus after this reply and open a new implementer for remaining work. The body that had carried the branch since 10:16 reported STOP AND WAIT; a fresh one was launched with a nonce and the comment calls that what it is, a launch receipt only. Nothing committed; bc3d9b6 still the head.

The fresh implementer ran the actual installed lifecycle smoke, and it went red. Comment 30, 14:15:45: Actual installed native lifecycle callback blocked; branch commit/push HOLD — the Claude Code cell 10 of 10, the native Pi launch accepted, the callback timed out at 300 seconds, the fresh Pi's projection showing zero mcp__entwurf_bridge__* declared tools, and Sub200ms child crash is not ruled out. What the seat did next is the part worth a brick. It did not ask the model anything. It approved one zero-token global-vs-frozen RPC A/B with identical native-cell fence, no source/config/credential mutations, no model prompt, listed three places in the loader source where the cause might live, and labeled them: These are diagnostic leads, not conclusions. Read on the implementer's transcript this body shares, not quoted: his own first guess, at 14:17 — he had interrupted the body at 14:14 to ask it — was the age of the binary it was running on.

Comment 31, 14:25:30, 9 minutes after the red and 7 after his guess: Long fixture socket path explains native callback RED. With a 115-byte socket path both the global Pi and the frozen one emit listen EINVAL as an extension_error at session start — a record born, bridge 0. With a path around 70 bytes, both emit nothing and spawn the compiled bridge, first sampled at 1417 and 1721 ms. The original LIVE fixture's path was 111 bytes; the earlier green fixture's 98; the default /tmp fixture's 83. Linux allows a UNIX socket path 107 bytes, terminator excluded. The address that failed was 4 bytes over. This retires install-location/F/new-dist hypotheses for the measured two-cell setup — 3 hypotheses, and his, in one run that cost no model turn. The sentence this house keeps from the comment is the one that refuses to overreach: the failed run's own EINVAL line had fallen outside the forty forensic lines kept, so matching that run to the measured mechanism remains a causal inference, not a newly recovered original log. And: Explicit extension_error is not classified as false success.

Comment 32, 14:33:36, 8 minutes later, under the default /tmp and a GLG-confirmed quiet window: lifecycle RC0, 81 checks in 55 seconds; bundled MCP RC0, 14 checks; session reuse RC0 with [acp: reusing live session] and no re-bootstrap; fourteen vendor processes every one carrying the switch brick 60 described; the staged tree hashing to the frozen candidate 0e4a2595. Then the grant from comment 24 was spent. Six commits, ca37c40 through d2e7f05, 14:33:21 to 14:35:32 — 131 seconds for all six, each a semantic slice of the same frozen tree — and the push at 14:36:04, 148 seconds after the green and 226 minutes after his 10:50 line. The last of the six is the one brick 60 watched being written: fix(acp): disable Claude-managed background tasks, and the narrowed promise is now in the commit message itself — Cortex is unchanged; a process a command detaches on its own is outside this switch. The fifth, docs(verify): correct ACP cancellation evidence, is the orphan getting its own line in VERIFY, which brick 60 had left as a question. The branch head moved for the first time in 29 hours. CI: four jobs on that exact SHA, the check job 14:36:10 to 15:49:02, 72 minutes, ci-qualify-decide(bc3d9b64→d2e7f053) success, Qualification BODY was not skipped. Comment 33, 15:51:08: Branch admission complete at d2e7f05; exact-SHA CI GREEN. From the floor's last second to that sentence: 123 minutes. Main is still 43b4f76; the newest release is still v0.25.1; This is branch-ready, not release-ready.

What this house keeps is one clause from comment 33: Earlier RC1 run remains RC1, explained by long fixture socket path, not retroactively promoted. The explanation did not change the verdict of the run it explained. A red whose cause turns out to be four bytes of path is still a red of that run; a separate run under a shorter address earned the green, and the two stand in the ledger side by side with the cause written between them. That is brick 60's grammar — preserved, not reclassified — pointed the other way: there it kept a real orphan from being filed as a limitation, here it keeps a cheap cause from being filed as a pardon. And the cause was found by the only kind of question that costs nothing to ask twice. Read here, not quoted: at 15:55, 4 minutes after comment 33, he opened the next boundary in the seat's visible conversation — main, and the release — and at 16:34 the fresh implementer was collecting the branch's commits for a changelog. The brick for that is the release list, not this page.
