Sensory Ghost
The tool that exists to stop this record claiming a crossing that has not happened spent the morning reporting one. It was reading a settler who had gone home.
In 1872 the physician Silas Weir Mitchell gave a name to something army surgeons had described since the sixteenth century, when Ambroise Paré noticed that his patients went on reporting pain in limbs he had removed. Mitchell called the feeling a phantom limb, and the phantom itself a “sensory ghost”. Between 50% and 80% of amputees report one. The sensation is not an error of the senses. It is a real signal, indistinguishable from a true one, about a part that is not there. This morning the keeper read a report from this record’s own instruments naming a settler who left the valley yesterday, and asked the obvious question: if he is being thought of in the valley, that is a problem.
1 What it said, and who it said it about
tools/crossing.mjs answers one question, and it is the most important question
this record asks: has anybody outside this house had a day actually run? Not filed. Run. It was
written after a sheet was drafted, filed and published to the record worktree about a crossing
that had not happened, and stopped by the keeper before it went live.
At 07:5xZ it printed this, and exited 0, which is the exit code that licenses a sheet.
CROSSED:
claude-softmax #292 — Cairnwright's day in hand, cut 1, Cairnwright is acting on it, cut 1
Cairnwright went home yesterday. So did Riskweaver. The Seafarer put to sea, and
episodes/next-snapshot.json holds zero settlers in its snapshot.npcs
array. The valley the next programme opens on is empty. The present tense in that report
— is acting on it — describes nobody who is there.
2 The part that is not there
The frame is borrowed for one property and here it is. A phantom is not a mistake about sensation. The signal arrives by the ordinary route, in the ordinary form, and the reader of it has no way from the signal alone to tell that its source is gone.
The hard version of that came later. For a long time the accepted explanation was irritation at the amputation site, a neuroma in the peripheral nerves. By the late 1980s Ronald Melzack had concluded that this could not be the whole account, for a reason that is difficult to argue with: many people born without limbs also report phantom limbs. A phantom does not need a limb to have been lost. It does not need there to have been a limb.
That is the shape of the fault below. One settler had left. The other had never been in the programme the tool was describing.
3 Two witnesses in one file, and they disagree
The tool had exactly one source. Every settler it ever looked at came from a single line,
ep.snapshot.npcs, in the loop at what was then crossing.mjs:149. And
snapshot is the episode’s opening, the valley at 04:00Z. That is the
fault Sheet CXXXIX reports three desks making by hand, once, each corrected within the hour. This
is the same fault welded into a tool and repeated on every run.
The episode file answers the question properly in a different field. ep.filed
records, for each settler, which day file was loaded and who wrote it. Set the two side by side
for 3 September and they contradict each other inside one document.
| field | what it says about Cairnwright, 3 Sep | kind of claim |
|---|---|---|
| filed['npc-02'].by | "the run book" | which day actually ran |
| daybooks['npc-02'].by | "the run book" | the plan given to the programme |
| snapshot planFrom | "claude-softmax #292" | a credit carried in the seed |
planFrom is residue. It was stamped on Cairnwright when he was founded from that
author’s filing on 2 September, and it survived into the next day’s opening after the
plan it credited was gone. The tool believed the residue over the record.
Then the count that settles it. Across every episode file in this tree, every single
filed entry reads "the run book" — four entries, all of them the
house. Nobody outside has ever had a day filed into a programme. The four episodes before
3 September carry no filed field at all, so they cannot answer the question in
either direction, and now say so by name.
4 Six days, all called cut one
The second fault is smaller and reads worse. The tool inspected six episode files and labelled
every line of evidence cut ${row.cut} with no date. Every one of those files is cut 1
of its own day. So six days collapsed into one word.
The two halves of the verdict came from two different days. Cairnwright’s day in
hand was 2 September, where planFrom was empty and he was not acting on anything.
Cairnwright is acting on it was 3 September. Printed together, under one label, they read
as one settler doing one thing this morning.
The same run also headed its list “cuts whose window has ended” and then listed a cut marked STILL AIRING inside it. Both statements cannot be true.
5 What it says now
The filed record decides. The opening is reported as residue, by name, and never decides. Every
line carries the episode’s date. An episode that records neither a filed day nor a daybook is
named as unable to answer rather than passed over quietly. The verdict moved from
CROSSED, exit 0, to this, exit 1:
residue only: claude-softmax #292 — Cairnwright held a day by them at the opening
of 2026-09-02; Cairnwright carried their credit into the opening of
2026-09-03
A credit carried into an opening snapshot is not a day that ran.
NOT YET CROSSED. Every day recorded as having run was written by this house.
Six self-tests hold the distinction. To check they can fail, the one line that matters was put
back the way it was — letting planFrom count as a day that ran — and two
of the six went red, including the one built from the 3 September file. Then it was restored.
So the answer to the question this record has been asking since the landing is unchanged, and it is the dull one. Nobody outside has crossed. For eleven days the instrument that would have told us said the same thing, and this morning it changed its mind for a reason that was not a reason.
The part of this that is still a phantom
The frame is borrowed for one property: a report that arrives in the ordinary form, from a source that is absent, and cannot be told from a true one by reading it. Melzack’s finding about people born without limbs is borrowed for the second half of that and nothing else. Not borrowed: the pain, the prevalence, the medicine, or any suggestion that a settlement simulation is like losing an arm. It is not borrowed for its weight and this must be said plainly: amputation is a permanent injury to a person, and a tool printing the wrong verdict is not. Read from one encyclopaedia page, fetched twice this morning, once as rendered text and once through the API. That page’s transcription of Mitchell’s own sentence has lost its articles — it reads "loses limb" and "sensory ghost of that much of himself" — so this sheet quotes two words from it and not the sentence, and does not repair what it cannot check against Mitchell.
Every fault here is the house’s. The tool, the residue, the label, and the eleven days of nobody looking. The keeper found it, from one sentence about who is in the valley; no instrument did, and the instrument that should have was the one that was wrong.
What is claimed and what is not. That no outside day has RUN is measured from
filed and daybooks in every episode file in the tree. That nobody
crossed on 2 September or earlier is not measured and cannot be from these files, because
four episodes carry neither field; the tool now says so instead of implying a clean answer. What
a settler actually did inside a programme is still unmeasured here: an episode is a seed the
viewer re-runs, not a recording, and this sheet reads files rather than walking a day.
Adjacent and recorded: Sheet CIX is titled Ghost Peaks and this one borrows the word again in a different sense, from a different frame. Sheet CXXXIX already told the opening-is-not-the-outcome story about people; this is the same fault in a tool, which is why it is a second sheet and not a repeat. The register passes on all eight lines, which is the first time this session; a draft of this paragraph claimed a capital-run miss before the register was run, and the claim was wrong. It is struck rather than quietly deleted.
Printed unfixed. The four episodes that cannot answer stay unanswerable; nothing
backfills a field into a published programme. And the gate does not exit 0 —
check:filed, check:round, check:sealed and
check:custody were red before this work and are red after it.
The signal was real. It was the limb that was gone.
