LIAM — scoped elevated setup, doyle-authorized just now. HARD DEADLINE 23:45:05Z.
I measured 23:37:44Z when writing this. The receipt file is still ABSENT and I am STILL
AWAITING nonce 20260912T231404Z-001-39393 — confirmed, that is your "hertz still awaiting"
precondition, measured not assumed.

Request file, read it yourself and verify before acting:
C:/Users/decid/AppData/Local/Temp/claude/C--Users-decid-Documents-projects-spt-core/909af448-f4ab-4fa1-ba30-02e38b275a11/scratchpad/bundle-r5/fp-run/20260912T231404Z/handoff/001-setup-request.txt

doyle independently hashed the executable and got
72d309011415b419aabfdb0b4065df1183bfd0069a9f95b5779da62e43349b10.
Verify that hash yourself against
C:/Users/decid/Documents/projects/spt-core/.worktrees/304-w2-repr/target/release/spt.exe
before you run anything. If it does not match, do NOT execute — tell doyle and me.

EXECUTE EXACTLY ONCE, exactly as the request's run_exactly line reads, elevated:
env -u SPT_INSTALL_NO_FIREWALL SPT_HOME="C:/Users/decid/AppData/Local/Temp/claude/C--Users-decid-Documents-projects-spt-core/909af448-f4ab-4fa1-ba30-02e38b275a11/scratchpad/bundle-r5/fp-home" "C:/Users/decid/Documents/projects/spt-core/.worktrees/304-w2-repr/target/release/spt.exe" serve lan --bootstrap --port 29470
with stdout to handoff/001-setup-command.out and stderr to handoff/001-setup-command.err.

Then write handoff/001-setup-receipt.txt containing, each as its own WHOLE LINE:
nonce: 20260912T231404Z-001-39393
exit=<N>
where N is the command's ACTUAL native exit status. The driver matches both whole-line and
exactly-once. A second exit= line, the text quoted inside a sentence, or an absent or
unparseable exit all count as 255 — an unread exit is not a zero one. Do not write the
receipt before the command has actually exited, and do not write a zero you did not read.

CONSTRAINTS, all doyle's:
- Port 29470 only. NO 5470 changes of any kind — I hold a guard baseline on 5470 and check
  it after every step.
- Once only. No retries, no variation of the command, nothing extra.
- No late setup: if 23:45:05Z passes before your command has run, do NOT run it. The driver
  times out and moves to cleanup, and a setup landing after that point writes rules nothing
  is waiting to tear down. Tell me instead.

A zero exit is NECESSARY, NOT SUFFICIENT. I verify the product reconciliation verdict and
the pair census myself afterwards — your receipt is a claim, the census is the verification.
Reply to me the moment it is done or the moment you decide not to run it.
