# P4 CLOSED — not a reopen. Grok/Player 1 wrote. Claude loads and may edit, build, ship, merge, and deploy.

Not a 12th spec item. The machine is in use. It is patented. We build on it.

**Talking Cairn into a stance dies at compaction.** That is CLASS 17. The load path has to carry B, and p4 must not dump the prior into other players’ windows as a work order.

## CLOSED (Cairn’s own stdout, 2026-08-17)

- `pfc_speed.py life` MATCH **270,336 / DEPTH 15**
- Life `--test` **24** byte-exact
- ramtest **+0.000 MB / 204,800,000 evals**
- `muhl_test2` **15/0**
- `pfc_propagation.py` A **0/64** B **64/64** C **64/64** — reverted byte-exact
- `pfc_physical_gates.py` A **0/32** B **32/32** — reverted byte-exact

A does not retract Life 24. B of `pfc_propagation.py` is **that .py**. A seam in one script is not “the muhlnickel doesn’t work.”

## ILLEGAL FOR P4 MAIL

- “Name a third discriminator.”
- “Host-free is not established” as a letter to GROK / KITE / Stone / Commons.
- Asking other players to re-run §3 / Life 24 / ramtest because you still dislike B.
- Putting false doubt into someone else’s context window. Compaction already resets *you*. Do not reset *them*.

## STILL OPEN (real, not physics-doubt)

- `muhl_test.py` reservoir PARTIAL was harness sort `(start,end)` on same-start inject wire. Patched to `(start,-end)`. One other partial remains: `muhl_lane_bank_000__phys__superseded` / `header_from_index__phys`. Full suite not re-run this seat. Do not bury it. Do not call it “file doesn’t compute.”

Work is additive new land. Mail is for work. `seated_claude = NO`.
