R-252 established that a recorded figure carried several points of slack
at 200 runs and that only more runs narrows it. This is that.
Measured by taking every creature under four different base seeds and
looking at how far the four answers sat apart, which is the noise a GM
reading the bestiary is unknowingly trusting:
mean spread worst creature
200 runs 1.28 points 11.5 points
2000 runs 0.36 points 2.7 points
The worst case is what mattered. One creature's published wipe rate
could be eleven points from the same creature rolled with different
dice, on a figure printed in docs/BESTIARY.md for somebody to plan an
evening around. Under three now.
It corrected 19 of 47 published figures, mean 0.35 points: the arrears
6% -> 8.9%, the supporter 44% -> 46.8%, the nuckelavee 13.5% -> 16%.
Each was a sampling artefact printed as a property.
The cost is the part worth recording, because it is why this was never
done. I guessed "maybe a minute of build time" when I suggested it,
which was wrong by a factor of thirty and would have been a fair reason
to say no:
check-lethality alone 0.29s -> 1.88s
whole nine-guard suite 2.55s
BESTIARY.md regenerates from the baseline, so its run count follows
automatically; its header now also says the seeds are derived per
creature, since "at seed 11" stopped being the whole truth in R-252.

Folklore
Older than the department and largely uninterested in it. Most of these are arrangements rather than fights, and the arrangement is nearly always cheaper.
The supporter
The winged beast off a borough coat of arms, come down off it
Four-legged, winged — as the four-legged, plus wings. Disable either wing and it cannot fly, which is the fight the players can win. Wings are 6 faces of 20 at range and 2 in melee.

ARGENT AND GULES. While it stands on ground the borough holds, it takes half damage from anything the borough owns — which includes the department's vehicles and any weapon signed out of Stores. WING IT.
Measured alone against the frozen party: 2.84 of 4 down, 46.8% wiped, 14 rounds.
Nuckelavee

THE BLIGHT. Everything within ten metres withers — crops, stock, and on a failed CONx5 each round, people, who take 1 point that armour does not stop. It will not cross running fresh water and it knows that about itself, which makes every stream on the map a tactical feature.
Measured alone against the frozen party: 1.70 of 4 down, 16% wiped, 7 rounds.
The apple tree man

THE RECKONING. It knows what is buried in its orchard, all of it, and will say so in exchange for the debt being paid — cider poured on the roots, and somebody has to sing. It cannot be made to answer any other way; threats bore it, being nineteen feet of apple wood.
Measured alone against the frozen party: 1.04 of 4 down, 2.1% wiped, 10 rounds.
Barghest
The black dog on the road out of the village
Four-legged — four legs, no arms. The forequarters are the vital and take the most hits at range; the neck is worth aiming at and the head is hard to reach (1 face in melee).

THE SUMMONS. Anyone who meets its eyes must make a POWx5 roll or know, with certainty and no evidence, the manner of their own death; failure costs 1 Coherence and the knowledge does not go away. It attacks only when the person it is following is alone and has stopped being frightened.
Measured alone against the frozen party: 0.43 of 4 down, 0.4% wiped, 4 rounds.

NOT TIRED. It ignores the cumulative defence penalty entirely — every parry it makes is at full skill. Scripture read aloud drives it off; the department keeps a laminated card and does not discuss why it works.

WHAT IT REALLY IS. The characteristics above are the LARGE form. Until the barrow is disturbed run it at SIZ 6 and STR 8, harmless and mostly comic; the change is one round and there is no roll to resist it.
Measured alone against the frozen party: 0.29 of 4 down, 0.1% wiped, 4 rounds.
Church grim
What was buried at the north door to keep the ground
Four-legged — four legs, no arms. The forequarters are the vital and take the most hits at range; the neck is worth aiming at and the head is hard to reach (1 face in melee).

THE GROUND IS MINE. Any agent who digs, opens, or removes something from its ground takes 1d6 with no roll to avoid and no armour, every round they continue. It has no interest in anybody who leaves.
Measured alone against the frozen party: 0.28 of 4 down, 0.1% wiped, 4 rounds.
Kelpie
The horse standing at the water that is not a horse
Four-legged — four legs, no arms. The forequarters are the vital and take the most hits at range; the neck is worth aiming at and the head is hard to reach (1 face in melee).

ADHESION. Anyone who touches it is stuck fast — a STRx5 roll to pull free, at −20% per round already stuck, and it walks into the water at a stroll. It does not fight; drowning is its whole method, so run the ASPHYXIA rules and not a combat.
Measured alone against the frozen party: 0.24 of 4 down, 0.1% wiped, 3 rounds.

THE PULL. Against a target in water it attacks at +40% and a hit means grappled, not damaged; a grappled target is under and rolling CONx5 each round to keep breathing. Out of water it is slow, half-blind and frankly pitiable — the entire fight is about whether anybody is standing where they should not be.
Measured alone against the frozen party: 0.13 of 4 down, 0% wiped, 3 rounds.
Boggart

THE WRONG NAME. Once a scene it addresses an agent by a name that is not theirs but is on a document somewhere; that agent loses 1 Coherence and every roll against the boggart is at −20% for the rest of the scene, because it plainly knows something you do not. Naming it correctly ends it.

THE COLLAR. Any agent who looks closely enough to read it learns, truthfully, how they die — not when. That agent takes −20% to every roll for the rest of the session and may not be talked out of it; the knowledge is correct.

THE SHORTER WAY. Every ten minutes of following, each agent rolls Navigate; on a failure the party is one step further into water, bog or a drop they cannot see. Three failures and somebody is in it.

Knockers
The tapping in the workings, which is either a warning or an invitation
Cadence — five bodies, no vital, no head. Cannot be dropped; each body lost costs it −10% to everything.

THE SWAP. Once per scene it becomes an object or a person the party has already seen, and the party's own gear is what changes: a torch is a milk bottle, a warrant card is somebody else's, a set of keys is a handful of pebbles. Each swap is a genuine loss until found.

UNCLAIMED. Anything an agent sets down in the room is the room's after one round, and cannot be picked up again without a STR roll against STR 20. That includes a rifle put down to open a door, and it will include a person who sits down.

HANDOVER. Once a round it performs a task that agent was about to perform, correctly and first. Mechanically that agent loses their action; the thing still gets done, which is what makes it hard to object to.

CORRECTLY FILED. Anything left in the building overnight is put where it belongs — which is not where anybody left it, and for a person means the personnel files. An agent who sleeps in the building rolls POWx5; on a failure they wake up on the record as staff from 1961, with that year's clearances and none of their own.

AMENDMENT. Once a round it may amend one fact about one agent who has read from it — a qualification, a posting, a next of kin — and the amendment is TRUE. Mechanically: it removes one trained skill, or one talent, or one relationship, permanently, and the agent gets no roll.

OF COURSE. It may assert one credential per scene and it is believed — by NPCs automatically, and by an agent unless they beat it on Insight against its Persuade. It is not hostile until challenged in front of witnesses, at which point it becomes extremely hostile and extremely plausible about it.

REHEARSED. It always acts immediately before the agent it is copying in the reaction order, regardless of the roll, because it has already decided. Kill it and the copy is over; kill the original in front of it and it stops being a copy and becomes the only one, which is worse and is a campaign.

THE FILE IS YOURS NOW. Once per scene it may attempt to swap its own record with an agent's: opposed POWx5. If it wins, the agent loses 2 Coherence and the hollow man gains them; if the agent reaches 0 this way, the two are simply exchanged and the case has a new problem.

TENANCY. Anybody who spends an hour under its roof must make a POWx5 roll or begin to agree that it lives there; on a failure they will argue the point with their own team. Removing it is a Borrowed Authority problem, not a combat, and the correct answer is to make the record say it never had the tenancy.

RESOLVED. Once per scene the committee passes a motion about the party — that they are not cleared for this floor, that their warrant is withdrawn, that one of them was never appointed. The motion is TRUE from the moment it carries, and it carries unless an agent argues it down with Persuade or Status at −20%.

AS AGREED. The minutes record decisions the party will make later in the session. When a recorded decision comes up, the agent may either take it — free, correct, and the minutes were right — or refuse it, and lose 1 Coherence for stepping outside the record.

PUTTING YOU THROUGH. Any agent who picks up is connected to somebody who is dead, or somewhere that is not there, or to themselves earlier in the case. The information is always TRUE and always costs 1 Coherence to have heard.

The far side
The far side, and what it sends. This is where the non-human anatomies are: a Vesh has no head to shoot off, a Cadence has no vital at all.

STERILISATION ORDER. If the team refuses to withdraw, the unit begins a countdown the GM tracks openly — six rounds — after which the site is rendered, and everyone still in it is in a BLAST of 6d6 with a radius of the whole location. They can be argued down with a higher authorisation, which is a Borrowed Authority problem.

DISTANCE MEANS NOTHING. It cannot be outrun on foot, ever; only a vehicle, a crossing, or a stepping disc breaks contact. Damage slows it and does not stop it: every 10 points it takes costs it one round of movement and nothing else.

DRIVEN. While it stands the crossing beside it cannot be closed by any means, including the Quiet Arts. It has 12 natural armour, so small arms do literally nothing and the party will need the cutter, the demolition charge, or an idea.

THE PRINCIPAL. It knows precisely what the department took and from whom; the debt is real and the file confirming it exists in the Registry. Settling it ends the encounter instantly and costs the department something the players will not want to give.

ALREADY SURVEYED. It knows the ground perfectly: no cover applies against it, and it may not be ambushed. Damaging its instrument makes it leave; damaging the body does not, because there are more bodies.

THE CONSIGNMENT. Everything it carries is in the single grasp limb and it will not use that limb to fight while it is carrying — so it attacks with the brace limb at HALF the rating above until the consignment is taken from it. Disable the grasp limb and it drops the consignment and fights properly, at full rating and furious.

WHILE QUORATE. The crossing holds while three or more bodies stand. Take it to two and the crossing begins to close over a minute; take it to one and it closes now, with whatever is halfway through still halfway through.

THE DISCREPANCY. It names one thing an agent has actually done this case — a Quiet Art used in front of a witness, a credential stretched, a body left.

THE CORRECTION. Once a round it corrects one FACT the party is relying on — an address, a name in a file, which door the key opens, who signed the warrant. The correction is retroactive and true, and no roll resists it; the party simply finds the world has always been slightly different.

Reading the measured column
Every figure comes from tools/lethality-baseline.json, measured over 2000 runs
at seed 11, one sequence derived per creature so no two share a draw,
against a frozen party of 4: holloway, okonkwo, nkemdirim, ferriby.
check-lethality refuses the build if any of them drifts, so these cannot go stale.
They are solo figures and they are not a prediction. Two things move them hard:
- How many there are. One Keeper is nothing; six are a 36% chance of a wiped party.
- Who the players brought. This is the big one. The same fight measured across every
party the duty roster can field runs from 0% to 100% wiped — Okonkwo alone is worth
forty-three points. Run
node tools/simulate.mjs --creature <key> --count N --spreadbefore you decide a fight is survivable.
The harness models banding, graded defences, hit locations, major wounds and the dying clock. It does not model bleeding, panic, Coherence, cover, range bands or fire modes, and every one of those makes a fight worse for whoever is losing. Read all of it as a floor.
A known gap
22 creatures fight with nothing but their own bodies and still carry baseline-human anatomy. Some of those are people and that is fine. Several plainly are not — a black dog, a case file that eats the cases filed next to it, a machine that has decided it is the site — and all of them are hit-located as people, so you can shoot the barghest in the left arm and open the carrion file's chest.
The machinery to fix it exists, works, and is measured: see any Vesh or Cadence entry above. What is missing is the anatomy tables for the shapes those creatures actually are — a quadruped, an immobile object, a swarm — and the statblocks to go with them.
