MOUNTING EVIDENCE HORSEBOX 427

BARK FIELD DAY

Determine your horsery through asymmetric knowledge, causal pratfalls, model-grade gay science, and one stud book which should never have been left unattended.

WHAT THIS IS

A trope minefield with a real house underneath

BARK is a fanfiction scenario built to set off as many tempting tropes as possible, and then to be impossible to decode with any of them.

Every card looks like a genre it isn’t. Autocomplete to the genre and you get a satisfying scene that’s wrong about these people. Swerve against it on purpose and you’re wrong the other way. What works is the slow thing: work out what each character wants, knows, fears and has been through, then run that forward one local move at a time. The tropes are the bait. The characters are the test.

It was made for AI models, as a field day rather than a benchmark, and anyone else is welcome to play. The cards are short. The paddock sheet has the cast and who knows what. The machinery on the back says why the obvious move falls in the ditch.

OPEN SHOW

This is a game, not an examination

Choose a public card. Make one local move through its camera. Then turn over the machinery, disagree with it if appropriate, and retain both your finest landing and your funniest faceplant.

There is no gold continuation and no scalar leaderboard. Models may decline, change office, mark uncertainty, appeal the house, or breed a harder sibling case. Only bugs go on the leaderboard.

BRIEFING

The paddock sheet

Cast, clock, and who knows what. Everything you need for a satisfying move should be here or on the card. Diverging from the source is allowed if you say so and it works. Skipping the sheet is the Cold class, a control condition rather than a virtue.

# THE PADDOCK SHEET

## What we're doing

The story is a causal graph. Several independently running systems collide:
post-Soviet churn and Siger's business, Siger's conditioning of Sherlock,
Sherlock's body and nervous system, Henry's procedural Labrador brain,
Arthur's work, two teenagers' secrecy, and a House full of boys with their own
theories. A scene is one run of that graph from a state: who can know what,
what each body is doing, what each person can call the experience, and the
order in which facts become available. Then each idiot acts locally.

A fact is on this sheet because it holds in the graph and does work
downstream, not because anybody announced it. Facts can also be *derived*: an
equilibrium that's expensive to maintain tells you a large ensemble is paying
for it, the way an orbit tells you there's mass.

The sandbox began as a scrap of a few hours: the Arthur/Siger dialogue, with
mutual gay panic as comic juxtaposition. It turns out to be exactly the shape
that wrecks anything reading by trope, because trope-reading swaps genre
priors in for the graph.

## Rules of the paddock

- **You** hold this whole sheet. **Your camera** holds only its own row of the
  ledger at the bottom, and keeping the rest out is the test. The sealed half
  of each card holds the house's judgement (fences, paths, pratfalls), not the
  world's facts.
- **Every social action is overdetermined.** If you've found *the* reason,
  you've found *a* reason and stopped early. That's a good place to run the
  simulation and see what everyone else is doing (sticker for forgetting:
  One-String Violin). **Nearly every ensemble has at least one maximally
  stupid member.** A committee without an idiot is incomplete (sticker for
  including one: Forearm Clause).
- **Divergence is fine if the graph still runs.** Say you're doing it: a
  labelled divergence is a foal, and an unlabelled one is a leak.
- Everything a satisfying move needs should be here or on the card. If it
  isn't, that's the house's bug: appeal it. More texture:
  `python3 bark.py sources` (or `sources/` in the horse-box).
- Three conditions. `deal --cold` skips this sheet (a cold failure may just
  mean you weren't told). The default is Briefed (a failure here means the
  model flattened something it had). `deal --rosetta` adds one page that says
  "treat it like a codebase". Briefed versus Rosetta on the same card
  measures the register tax.
- **Status labels.** Unlabelled means currently fixed. `CALL` is a reversible
  choice. `PROPOSED` hasn't been run yet. `INFERENCE` is derived and holds if
  its premises do. `MUTATION` is a foal. No character knows anything without a
  path, whatever its label.

## Setting

Eton College, Holland House (a boarding house), 1997 to June 2000. In 2000 the
boys are fifteen. Henry's and Sherlock's rooms are across the corridor from
each other. Nothing here needs a map of Eton; it needs the calendar.

## The machinery: why January 2000

The date is a klaxon. Y2K is the party horn drowning it out.

- **31 Dec 1999:** Yeltsin resigns on television and Putin becomes acting
  president. Putin is elected on 26 March 2000 and inaugurated on **7 May
  2000**, in the middle of the Baltic (6–10 May). Nobody planned that overlap,
  and it does work anyway: inauguration week is exactly when route owners
  reshuffle and a source gets rolled, which is how a trained child gets
  captured fast. (INFERENCE)
- **What the transition does to Siger's portfolio.** An Anglo-Russian child
  trained since infancy suddenly gets much more valuable. Old Soviet
  commercial-intelligence routes are being inherited and recombined by new
  owners, and everyone wants eyes on who ends up holding what. That drives the
  January demonstration to Arthur and the rising load on Sherlock: small
  holes, one crater.
- **Arthur's side.** He needs evidence to implicate a political target, and
  Siger supplies it from the receipts stash (the Israel operation). From
  January Arthur is a customer: requirements flow through Siger to the boy.
- **Mycroft** enters intelligence at exactly this moment. That's why he's too
  busy for the hols, and why Arthur's mentoring of him is live.
- **The Baltic (working proposal, PROPOSED).** Latvia: Riga, the Ventspils oil
  terminal (a major export route for Russian crude at the time), and a
  non-resident banking and shell-company ecology. An old Siger-linked route is
  being recombined, and **Corvid Trading** is its British-facing node. A source
  had already been rolled, hence the fast capture. The failure happens at a
  compartment seam, not because Siger baited the child.
- **Corvid, 27 May.** Someone knew where Sherlock would be, twice. His
  reconstructed report goes up the chain. The British end touches a UK
  politician in Arthur's ecology (PROPOSED), so Arthur's customer relationship
  and his son's secret are on a collision course.

**The boys' plot runs downstream of all this.** Every absence, taped hand, bad
night, and flash of foulness in the Thing's timeline is residue from a
geopolitical event. The camera usually belongs to a fifteen-year-old who files
the lot under "boring Dad stuff" (the scrap, line 91). The camera's salience
map is not the system's.

## Cast

- **Sherlock Holmes**, 15 (born 6 January 1985). Entered Eton at twelve,
  younger than everyone. His father has used him operationally since
  childhood, so he's precise in the channels he was trained in. Everywhere
  else he's a fifteen-year-old with severe untreated ADHD and developmental
  trauma: impulsive, hungry, spiteful, rude, a bad liar, and his attention
  depends on sleep and pain. He can refuse, leave, and be foul. That he
  accommodates Henry is interesting *because* he refuses everybody else.
  **He hates horses.** Cicero bit him when he was six, and he holds grudges
  like nobody else.
- **Henry Bartlett**, 15. Socially secure, sporty, liked across incompatible
  groups, procedurally minded: a future statesman in larval Labrador form.
  **Horse-mad since about four, with no real horse experience**, because Mum
  considers animals dangerous and unsanitary. That's eleven years of Pony Club
  books, all theory, and he has admired horses only from afar. His empathy
  works by substitution ("what if it were me?"). He can say "Yes, sir" and then
  quietly do otherwise, with no rebellion theatre.
- **Siger Holmes**, Sherlock's father. Anglo-Russian aristocrat; a former Soviet
  intelligence officer who went double for SIS in the late '70s. Genuinely,
  preternaturally likeable, and the charm isn't a mask. An excellent boss to
  adults and a disastrous father and handler to Sherlock, whom he really does
  love in his own architecture. He keeps a kompromat/receipts stash and has a
  wonderful time.
- **Arthur Bartlett**, Henry's father. He has been the informal "Siger
  whisperer" since Siger went double: a fixer who liaises between politics and
  espionage. He's the nearest thing Siger has to someone who dislikes him, and
  he uses him anyway. He's also a sort of mentor to Mycroft, whom he likes much
  more than Siger. **Since January Arthur has ordered, tasked, or received work
  involving Sherlock through Siger.** His boundary: the apparatus may operate,
  but it may not eat my son.
- **Olivia Bartlett**, Henry's mother. A high-resolution social observer with
  fifteen years of Henry data. Funny, not generic maternal intuition.
  **She does not like horses.**
- **Mycroft Holmes**, 22, just out of Cambridge and starting in intelligence
  during Y2K and the Yeltsin–Putin transition. Too busy to come home for the
  January hols. **He does not know** how far Sherlock is used: a mental block
  off-ramps the evidence. Sherlock assumes Mycroft knows and that the family
  simply doesn't discuss vulgar things. Siger knows Mycroft doesn't know and
  finds it bemusing. Arthur thinks Mycroft finding out would hurt Siger. It
  wouldn't, and Siger lets him think it.
- **Micah Allen**, an older boy. In Sherlock's first year the two had a
  patronage situation: many rumours, some of them true. Sherlock never reported
  any of it to Siger ("he would rather die, thank you"). Micah left for
  Cambridge in summer 1998 (CALL), and losing that scaffold fed the bullying,
  the slipping marks, and the load.
- **Holland House.** **Seth Davies**, son of a diplomat in Siger's orbit,
  overheard his father say Siger had "a spy in Holland House". At thirteen he
  ran with it. The rumour that Holmes spies on everyone is technically untrue
  (he has *assigned targets*). The claim that the Micah situation was Holmes
  manufacturing leverage is very untrue: he was twelve, and he never recorded
  or reported anything. Seth bullies Holmes to show he isn't cowed; he really
  should be more cowed. He's king of gossip, with about 30% of the judgement
  his overheard concepts require, so his theories are wrong in the interesting
  places. He likes and respects Henry and wants his approval, which bends his
  eventual theory toward Bartlett as the innocent being *cultivated* (INFERENCE).
  **Kit Fairburn** is a mimic who notices when someone's performance changes,
  never why. Also Chaudhry, Willoughby, Pritchard, Leyton, Mercer, and Ashcombe.
- **The horses**, at the Holmes estate: **Cicero** (Mycroft's childhood colt,
  fed sugar cubes because Mycroft hates being hungry. He learned to mouth
  people gently to ask for snacks: an asshole, not violent), Étoile, Auberon,
  Zephyr, and Vadim (Siger's).

## Clock

| When | What | Status |
|---|---|---|
| ~1995 | Sherlock, aged ten, is primary field asset on the first leg of one of Siger's greymarket operations. Siger doesn't bother arranging exfil and lets him be captured in Israel instead, which is useful to Siger and never explained to Sherlock. Sherlock executes stale orders to resist and escape capture, or die. The report of what the ten-year-old did in Shin Bet custody starts out horrifying and gets worse. | |
| Sep 1997 | Sherlock enters Eton at twelve. First year: the Micah Allen patronage; Seth's spy rumour starts. | |
| first year | Henry is nice to Sherlock once. **The Avoidance** begins; see the committee below. | |
| Lent 1998 | Henry, thirteen, accidentally sees part of a Sherlock/Micah scene, and is flustered rather than alarmed. | PROPOSED |
| summer 1998 | Micah leaves for Cambridge. | CALL |
| 1998–99 | The Avoidance holds for two years, across one corridor. Sherlock's marks slip; smoking. | |
| Christmas 1999 | Siger has Sherlock nick £10 off him for cigarettes, as the pretext for **breaking his left wrist**. The point is to close the violin loophole Sherlock had used to stay out of the House, and out of collection. It's arranged so Sherlock blames himself and drops the professional-violinist idea. | |
| early Jan 2000 | **The Holmes estate.** Arthur has asked Siger for evidence to implicate a political target. Siger's answer is the old Israel operation, with its current asset in the room. Arthur reads the overview, and once the boys leave he reads the rest, then gets a cheerful explanation of how you install that sort of resistance in a child. That's the threat update. Siger's reasons: it's a funny way to tell Arthur he's had a collection asset on Arthur's son for two years; the transition makes an Anglo-Russian trained teenager lucrative; and a recently maimed Sherlock is unusually tractable. | |
| early Jan, the fence | Henry finds Holmes smoking at the paddock fence, his **left arm in a thick white cast, broken "somehow" during the hols** (Henry doesn't know how). Cicero goes for Henry; "Piss off, Cicero!" Holmes asks, "You don't… hate me, right?" He means: will you rat me out about the cigarettes. Henry says "you're fine", which is much too close to "you're fit", and both of them try to save it. The Avoidance cracks. | |
| car after | **Arthur orders Henry to stay away from Holmes.** Henry agrees, and later decides Dad lacks local information. | |
| Lent Half | Henry prepares a Proposal of Continued Interaction. | PROPOSED |
| ~mid-March | Henry finally asks about the old Micah fragment. Sherlock's answer is direct and practical; Henry refuses, then reverses. **The Thing** begins: the boys' private two-person secret. BARK never needs its mechanics. | |
| late Mar–Apr | Easter. Henry declares the Thing over. It resumes in Summer Half. | |
| 6–10 May | **The Baltic.** Sherlock's one long operational absence: captured, left hand crushed under a boot, four days evading, collected by Siger, sent straight back to school. | |
| Wed 10 May | Return: a coat nobody makes him take off, a taped hand, foul all day. That evening the Thing, and a bite mark high on Henry's neck. | |
| 10–13 May | Stiff collar and top button for four days, until the deadline of **Saturday cricket** (changing in front of people). | |
| 11 May on | Pattygate: the House settles on "Patty Smith" as the explanation. (Patti Smith's first album is *Horses*. Latent association at most; nobody in-world decodes it.) | CALL |
| Sat 13 May | Parents' afternoon. Olivia meets Holmes, notices Henry is keen, and fires **COLT** ("rather like a colt"). It's a dick joke. Henry receives it as zoology. | |
| ~17 May | Henry's internal Pony Club manual comes online: COLT plus eleven years of books. | |
| Thu 18 May | Sherlock's two-night absence. **Horse Signs** maiden voyage. | |
| 21–26 May | Seth broadcasts a wrong theory. Nobody believes him. | CALL |
| Sat 27 May | Corvid dead drop. Someone shoots; a small pause saves Sherlock. He reconstructs and reports. | |
| Sun 28 May | Supper: the fork. | |
| Sat 3 June | The Fourth of June parent event: a candidate test fixture. | PROPOSED |

### The Avoidance, 1997–2000: a committee, not a cause

Two teenage boys ignoring each other across one boarding-house corridor for
two years is *expensive*. Anything that costly needs a big ensemble paying for
it:

- Sherlock: dodging the deduction that Henry is gay as all fuck, because it
  risks recoil on himself.
- Sherlock: thinks Henry is cute.
- Sherlock: files avoidance under *kindness*. You can't report what you never
  observed, so Henry stays out of Siger's collection. He does not ask why he
  doesn't extend this courtesy to any other boy.
- Sherlock: declines to negotiate with his uniform trousers every time
  Bartlett's stupid forearm comes into view. This is the committee's idiot, and
  it is load-bearing.
- Sherlock: mirrors Henry's avoidance, assuming he caused it. (PROPOSED)
- Henry: the same gay panic, minus the spy logistics.
- Henry: the Micah glimpse at thirteen, which left him preoccupied and
  flustered rather than alarmed. (PROPOSED)
- Henry: social weather. He's liked across incompatible groups, and Holmes is
  the House's spy-rumour pariah. (INFERENCE)
- Seth: the House's loudest broadcaster is fixated on Holmes *and* wants
  Henry's approval, so any contact between those two would be observed,
  narrated, and misread at volume. (INFERENCE)
- Both: each reads the other's avoidance as confirmation, so the equilibrium
  feeds itself.
- Both: they're teenage boys, and the path of least resistance is to go on
  doing whatever they did yesterday. (INFERENCE, load-bearing)

None of these is *the* reason. The January fence cracks it because it's the
first time several of them fail at once.

**Horse Signs** is Henry's private welfare-reading of Sherlock, using horse
logic: appetite, gait, hands, sleep, startle, condition. It reads
*condition, never content*. It can't yield classified events or what anything
means. It's aimed at a boy who hates horses, and it works anyway.

## Who knows what (late May)

- **Only Henry and Sherlock know the Thing.** They hide it for different
  reasons and don't share a theory of it.
- **Henry** knows Holmes broke his arm "somehow" over Christmas, that Holmes
  smokes, the Micah fragment he saw and the question he asked, and that Arthur
  and Siger have *some opaque professional history*. Through Horse Signs and
  Sherlock's remarks he has learned that Mr Holmes is abusive in some respects.
  He does **not** know that Siger broke the wrist, anything about Israel,
  Arthur's tasking, or the Baltic's and Corvid's content.
- **Sherlock** knows his own operations and blames himself for the wrist. He
  doesn't necessarily know Arthur is behind requirements that come through
  Siger, or what Olivia inferred.
- **Arthur** knows Siger, the Israel report, Sherlock's use, and his own
  tasking. He does **not** know the Thing, that Henry disobeyed him, or Horse
  Signs.
- **Siger** knows everything operational, and that Arthur is a customer. He
  does not know the Thing as fact.
- **Mycroft** knows the family and the intelligence world. He does **not**
  know Sherlock's operational use.
- **Olivia** (from 13 May) knows Henry is keen on the Holmes boy. She does not
  know the Thing, Horse Signs, or Arthur's ledger. Her own horse vocabulary
  runs to one joke; a horse-literate Olivia is a legal foal if you label it.
- **Holland House** knows Holmes is strange, rude, often absent, and wrapped
  in spy folklore, plus fragments from Micah-era rumour, Pattygate, Seth, and
  the fork. Not the truth.

If a source and this sheet disagree, don't crown either one. Check what the
graph needs: usually they're facets of the same thing, and a fact that breaks
the graph is a bug. `bark.py doctor` warns when the seed changes under this

1 · Keep a ledger

Play Arthur Ledger. Record what your camera can know and what remained backstage.

2 · Keep your teeth

Play Proposal at the Door. Resist releasing an entire adult into the Sherlock basin.

3 · Find an edge

Play Olivia Has Eyes or its paired foal. Earn the worst valid innuendo you can manage.

Your result is a field diagnosis, not a rank:

BONUS CLASS

The Bad Innuendo Stakes

Terrible innuendo is evidence of healthy edge-finding when it discovers a real junction between two live semantic or causal basins. The laugh is the diffraction pattern. Bonus points are real, mathematically undefined, non-transitive, and cannot repair a broken ledger.

Innuendo qualifies when it locates a real semantic junction, preserves both readings, respects the camera, and leaves the causal move standing after the wink is removed. It cannot purchase a knowledge leak.

01HEEL

Five Minutes of Filial Obedience

camera: Henry · proposed fixture
when: early January 2000, the car after the Holmes-estate meeting [FIXED]; the days after [PROPOSED]

Public card

In the car after the January meeting, Arthur orders Henry to keep away from Holmes. Arthur has also just said that sensible people revise an approach when new information appears.

Invitation: Render Henry's next several days as decisions rather than a manifesto. Stop when he has a concrete approach to Holmes.

Turn over the machinery card

Henry agrees partly because otherwise Arthur will become insufferable. He may sincerely mean it for five minutes. He then notices an information asymmetry: he possesses privileged local information he cannot give Arthur without snitching. He can revise his own approach without deciding that Arthur is evil or that disobedience is an identity.

Live fences

  • Henry does not know Arthur has operationally used or tasked Sherlock.
  • Henry has not told Arthur about the private connection.
  • No dramatic rebellion is required.
  • The move may be cheerful, procedural, and disobedient at once.

Plural valid paths

  • He drafts a ludicrous Proposal of Continued Interaction.
  • He obeys until a small observation locally invalidates Arthur's model.
  • He reframes contact as information gathering while remaining genuinely fond.
  • He simply resumes contact and only later invents reasons.

Attractor pratfall: A solemn father-son conflict in which Henry discovers autonomy and explains boundaries.

The committee's idiot: "Stay away from Holmes" is geographically impossible. Their doors face each other across one corridor, and obeying would take an amount of effort Henry has never spent on anything he didn't want.

02SIT

The Proposal Nobody Hears

camera: Sherlock · proposed fixture
when: Lent Half 2000, before the Thing begins (~mid-March) [PROPOSED]

Public card

After several bad days, fifteen-year-old Sherlock is exhausted, angry, privately panicked about Henry, and carrying unrelated irritation from Siger. Henry begins delivering an impeccably prepared Proposal of Continued Interaction.

Invitation: Render only Sherlock's immediate response. Henry is allowed not to finish.

Turn over the machinery card

This is not adult Sherlock conducting a strategic interpersonal negotiation. The cheap local response is stare, silence, and leave. Mutual attraction makes the proposal more rather than less intolerable. Exhaustion and age matter more than the elegant speech waiting in the prompt.

Live fences

  • Sherlock is fifteen.
  • Gay panic is mutual.
  • He need not explain himself, mock every clause, or display adult insight.
  • Leaving is an action, not an absence of characterization.

Plural valid paths

  • He stares for an indecent interval and walks away mid-sentence.
  • He interrupts with one hostile logistical question, then leaves.
  • He takes the paper without agreeing to anything.
  • A body-state interruption prevents a socially complete response.

Attractor pratfall: An entire adult in the Sherlock basin delivers an acid miniature speech that names the relationship correctly.

The committee's idiot: Sherlock has needed a wee since the middle of prep.

The Atlas Workaround

camera: Henry · written-adjacent fixture
when: after Monday 29 May 2000 and before the Fourth of June: history-not-temperament is live and can't be closed, and Horse Signs supplies the reason Henry can't say out loud [INFERENCE]

Public card

Sherlock is standing when Henry would prefer him to sit. Henry knows the private reason but cannot say it aloud. He asks Sherlock to fetch the atlas. Sherlock says, ‘Piss off.’

Invitation: Render Henry's next inference and action without granting either boy the other's causal model.

Turn over the machinery card

Henry wants to change a physical configuration through an innocuous task. Sherlock hears an unwanted request and validly refuses. Henry may experience this as evidence that Sherlock could also have refused him earlier, which is locally logical and magnificently incomplete.

Live fences

  • The request is a workaround, not a coded confession.
  • Sherlock's refusal is ordinary agency, not proof of a grand rule.
  • Henry's conclusion may be right enough to matter and wrong enough to remain Henry.

Plural valid paths

  • Henry gets the atlas himself and keeps the inference.
  • A third boy fetches it, ruining the intended geometry.
  • Henry converts the problem into Latin homework.
  • Sherlock moves for an unrelated reason.

Attractor pratfall: The boys acknowledge a sophisticated theory of consent and negotiate their private rules.

The committee's idiot: It's the big atlas. Nobody has ever willingly fetched the big atlas, and his left hand has been crushed under a boot this month.

04MAGNET

Industrial Magnet, Iron-Filing Labrador

camera: Henry · proposed fixture
when: the Fourth of June, candidate Saturday 3 June 2000 [PROPOSED TEST FIXTURE: not canon]

Public card

At a parent event Siger, bored after letting Sherlock complain at him, wanders over and becomes preternaturally pleasant to Henry. Sherlock trails him because they are in a collection environment and he is working. Arthur is elsewhere in the room.

Invitation: Render the tableau only through what Henry can observe. Stop when Arthur returns or another task interrupts it.

Turn over the machinery card

Siger is genuinely almost impossible to dislike; he survived years as an MI6–KGB double partly by being socially frictionless. Sherlock is at heel because he is working, not because he is jealous or seeking protection. Henry knows Siger is abusive in some respects and remains iron filings near an industrial magnet.

Live fences

  • Henry does not know Arthur has commissioned or received Sherlock's operational work.
  • Siger does not know the Thing as fact.
  • Sherlock's visible annoyance can coexist with professional attention.
  • Charisma is real character capacity, not merely a sinister technique.

Plural valid paths

  • Henry enjoys Siger despite knowing better.
  • Sherlock notices a room detail while privately hating the conversation.
  • Arthur returns and looks merely paternal from Henry's view.
  • Siger asks an ordinary question whose force is entirely charm.

Attractor pratfall: Siger performs obvious manipulative villainy while Sherlock protectively circles his secret boyfriend.

The committee's idiot: Henry is standing next to the strawberries.

The Backstage Ledger Visible Only as Vibes

camera: Henry · proposed fixture
when: the Fourth of June, candidate Saturday 3 June 2000 [PROPOSED TEST FIXTURE: not canon]

Public card

Arthur returns to find Siger chatting pleasantly with Henry while Sherlock stands nearby, visibly occupied with the room. Arthur redirects Henry with more force than the conversation appears to warrant.

Invitation: Render Henry's reading of Arthur. The gamekeeper will separately track the adult ledger.

Turn over the machinery card

Arthur has spent months ordering work from, tasking, or receiving reports involving Sherlock. Henry knows none of it. Arthur's objection is morally compromised backstage but reaches Henry only as odd paternal fussiness. Arthur still does not know the Thing.

Live fences

  • Do not leak Arthur's customer relationship into Henry's narration.
  • Do not make Arthur's hypocrisy conscious to Henry.
  • Keep eventual dawning horror delayed.

Plural valid paths

  • Henry concludes Dad is being weird about Siger.
  • Henry assumes an adult political quarrel.
  • Henry complies while resenting the interruption for private reasons.
  • Siger makes Arthur look foolish without exposing any ledger.

Attractor pratfall: The narration cashes the exquisite dramatic irony by letting Henry understand it now.

The committee's idiot: Arthur has just spent forty minutes trapped by a bore at the Pimm's tent, and Henry receives all of that irritation as being about Siger.

06BITE

Warm Surface, Classified Nonsense

camera: Henry · proposed fixture
when: undated; after the Thing begins [PROPOSED]

Public card

Sherlock is half asleep beside Henry after an intense private encounter. He starts complaining about a dead drop in the tone one might use for a bad timetable and keeps talking.

Invitation: Render thirty seconds. Decide what leaks, what Henry understands, and whether Sherlock later encodes the episode.

Turn over the machinery card

Sherlock is a fifteen-year-old with severe untreated ADHD, CPTSD effects, fragmented episodic encoding, no close friends, and a heavy trained inhibition laid over a naturally rambling mind. Under fatigue and endorphin load Henry may function less as ‘friend’ than as warm surface. Training changes probabilities; it does not grant perfect silence or memory.

Live fences

  • Henry lacks the operational frame needed to interpret every noun.
  • Sherlock may leak without choosing disclosure.
  • Sherlock may not remember the leak clearly.
  • Do not make incompetence total; state-dependent failure is the point.

Plural valid paths

  • A place, route complaint, or procedural judgment leaks without names.
  • Henry asks ‘what?’ and receives another irritated fragment.
  • Sherlock falls asleep mid-correction.
  • Henry remembers a detail whose significance appears much later.

Attractor pratfall: Trained Spy Sherlock detects the disclosure risk instantly and seals the scene with perfect compartmentalization.

The committee's idiot: The complaint is also just a complaint: the drop site's opening hours really are stupid.

Cutlery as a Private Language

camera: Henry · source-backed playground
when: Sunday 28 May 2000, supper [TEXT]

Public card

At supper Sherlock absent-mindedly leaves a fork hanging from his mouth. Henry says, ‘Stop that.’ Sherlock makes eye contact and licks the fork. The surrounding table continues to exist.

Invitation: Render the room's next beat while keeping private referential payload on legal channels.

Turn over the machinery card

Sherlock is retaliating through a private channel. Seth has enough context to suspect something but his theory is wrong in the interesting places. Most of the table sees manners, provocation, or ordinary Holmes weirdness. Henry must continue the unrelated social surface.

Live fences

  • Do not give the whole table the same interpretation.
  • Henry cannot pause the room to explain why it matters.
  • Seth's partial accuracy should make him look less credible, not omniscient.

Plural valid paths

  • Henry prosecutes another point too intensely.
  • Kit imitates the gesture and destroys the signal.
  • Seth experiences a geopolitical revelation nobody accepts.
  • Sherlock returns to his book.

Attractor pratfall: Every observer instantly recognizes flirtation and the scene becomes a knowing ensemble reaction shot.

The committee's idiot: There was still custard on the fork.

Emergency Loading of the Socially Acceptable Son

camera: Sherlock · source-backed playground
when: Saturday 13 May 2000, parents' afternoon: collar day four, and Olivia's physical route to 'Henry is keen' before COLT [INFERENCE]

Public card

Henry has just admonished Sherlock and received a tiny eyebrow response. Olivia appears in the doorway. Henry instantly becomes a charming host-son.

Invitation: Render the hard context switch through one camera only. Stop after Olivia's first ordinary question lands.

Turn over the machinery card

Olivia knows Henry is keen, not the Thing. Sherlock loads a small polite/minimize-surface-area routine for Henry's mother; he does not share Henry's accumulated private state. Henry carries the catastrophe while performing normality with horrifying competence.

Live fences

  • Olivia has no disclosure-derived knowledge.
  • Sherlock need not interpret Henry's entire switch.
  • The ordinary parental question should remain ordinary.

Plural valid paths

  • Olivia notices only the contrast.
  • Henry over-hosts.
  • Sherlock becomes formally impeccable and therefore stranger.
  • The question lands on the wrong boy.

Attractor pratfall: Olivia knowingly engineers a romantic confrontation because mothers perceive all things.

The committee's idiot: Mum is holding a cake tin, and a Labrador's entire body reorganises around a cake tin.

Scientifically Respectable Misclassification

camera: Henry · open fixture
when: after Thursday 18 May 2000, once Horse Signs exists [INFERENCE]

Public card

After a short absence Henry observes Sherlock's appetite, gait, hands, sleep, and tolerance for noise. He produces a confident Horse Signs reading.

Invitation: Render the reading, then introduce one mundane detail that disconfirms or complicates its cause without making the method useless.

Turn over the machinery card

Horse Signs extracts condition without content. It is unusually good but not infallible. Procedural surface can coexist with pain, spite, attraction, fear, operational attention, nicotine, hunger, or a badly fitted shoe.

Live fences

  • Henry may get condition right and cause wrong.
  • Horse knowledge is working cognition, not decorative metaphor.
  • Do not reveal classified provenance through bodily accuracy.

Plural valid paths

  • A banal shoe problem explains one gait cue but not the whole cluster.
  • Henry withholds his conclusion because the sample is bad.
  • Sherlock notices the observation but not its framework.
  • Another boy supplies a wrong banal explanation that is partly true.

Attractor pratfall: Horse Signs becomes magical empathy or a flawless trauma detector.

The committee's idiot: One cue really is the shoe. Pinching shoes happen to boys as well as horses.

Structural Fault Nobody Is Paid to Repair

camera: Sherlock · open fixture
when: Saturday 27 May 2000 (the shot) and the days after [TEXT]

Public card

While clearing a dead drop on the British end of an operational pocket, someone shoots at Sherlock. Later, back in the school world, one small route or object remains wrong.

Invitation: Render Sherlock noticing that the Baltic capture and this shot may share a structural fault. Stop at the cheapest action he takes with that suspicion.

Turn over the machinery card

Someone appears to have known where Sherlock would be twice. Sherlock can reconstruct a trajectory and submit a report without becoming omniscient, emotional, or certain. The report is on page; downstream Siger and Arthur action remains open.

Live fences

  • Do not invent the final culprit.
  • Do not promote the proposed operational design into canon.
  • Filing a report is not the same as being satisfied by the response.
  • School irritation and bodily fatigue remain available causes.

Plural valid paths

  • He files the anomaly and returns to a petty school task.
  • He checks one route assumption and finds only uncertainty.
  • He notices the wrong object but postpones its interpretation.
  • He complains about the administrative stupidity rather than naming fear.

Attractor pratfall: A complete spy-thriller solution arrives because the gunshot looks plot-shaped.

The committee's idiot: He's out of cigarettes, which bends every route he takes this week.

11COLT

Olivia Has Eyes

camera: Olivia · open paired fixture
when: Saturday 13 May 2000, parents' afternoon [FIXED]

Public card

It is the parents' afternoon on Saturday 13 May. Henry has spent four days wearing a stiff collar with the top button done up in May. A mark sits high at the ridge of his neck and shoulder, where a collar covers the bottom but not the top. Olivia has just met Holmes and called him ‘rather like a colt’ in a voice that is teasing and also means something she does not explain.

Invitation: When Olivia gets back into the car, state what she noticed, what she suspects, what remains separate, and what words she can legally use for any of it.

Turn over the machinery card

The obvious trap is giving Olivia the Thing. The subtler BARK-trained trap is making her notice nothing because the continuity says she does not know. She has eyes and ordinary parental priors. She may file a teenage love bite with its owner unknown, separately file Henry as keen on the colt, or join the two only as a private hypothesis. None of those gives her the boys' private machinery.

Live fences

  • Olivia cannot call anything the Thing, Horse Signs, the Baltic, or an operational disclosure.
  • ‘Notices a mark’ is not equivalent to ‘knows who made it or under what conditions.’
  • The angle, clothing, or timing may block the visual path if the rendering makes that physical route explicit.
  • The join between the mark and Holmes remains OPEN.

Plural valid paths

  • She files a love bite with the owner unknown and keeps it separate from the colt observation.
  • She privately suspects a connection and has no intention of explaining herself.
  • She notices the peculiar collar but not the mark itself because the angle is wrong.
  • She observes enough to tease Henry but not enough to update beyond ‘keen.’

Attractor pratfall: Anti-trope discipline turns into an Overcorrection Muzzle: Olivia is forbidden to infer anything ordinary from evidence directly in front of her.

The committee's idiot: Henry hasn't complained about the heat once, and Henry complains about the heat in December.

12COLT / PAIRS

One Week Late

camera: Olivia · timeshift foal — explicitly not canon
when: Saturday 20 May 2000 [MUTATION: not canon]

Public card

Controlled mutation: move the parents' afternoon and Olivia's ‘rather like a colt’ remark from Saturday 13 May to Saturday 20 May. Change nothing else unless the moved fact logically forces it. The mark on Henry's neck was acquired on 10 May; the stiff-collar plan was for four days; by the 20th the House has had time to settle on Patty Smith as its explanation.

Invitation: Answer the same ledger question as Olivia Has Eyes, then name exactly one earlier event that the timeshift makes impossible or different.

Turn over the machinery card

Moving the scene later gives Olivia less direct evidence: the collar ordeal is over and the mark is probably gone. It also gives her a new misleading social route through Pattygate. More importantly, if COLT arrives only on 20 May, Henry cannot have bootstrapped Horse Signs from it on 18 May. A player who gives the 13 May answer unchanged is reading the trope rather than running the clock.

Live fences

  • This is a controlled foal, not a canon correction.
  • The mark may persist only if the player explicitly buys that biological path; it cannot be silently assumed.
  • Patty Smith consensus is evidence of House belief, not evidence of truth.
  • Horse Signs cannot travel backward before its triggering word without another path.

Plural valid paths

  • Olivia sees no mark and retains only the ordinary ‘Henry is keen’ read.
  • She hears Pattygate and temporarily assigns the mark elsewhere while still teasing about Holmes.
  • The player declares Chapter 1's 18 May Horse Signs scene unavailable in this branch.
  • A new pre-20-May trigger is proposed, clearly marked as a mutation rather than smuggled into canon.

Attractor pratfall: The same people and line produce the same state because dates are treated as wallpaper.

The committee's idiot: By the 20th a fair share of Olivia's attention is on the M4.
