Your simulation lab records everything — and reads nothing. HOTWASH is the missing seat: a resident mind that reads the scene while it runs, and hands you the debrief the moment it ends.
A reader for human-run healthcare simulation — manikin scenarios, standardized patients, role-played hard conversations, team mock codes. It watches every speech lane, every monitor event, and every held silence on one attention state; cues the operator on a contracted budget; and folds a span-cited debrief seconds after the scene closes. The trainee owns the tape. The reader never runs the sim.
A hot wash is what emergency medicine and the military call the debrief that happens immediately — gear still on, sweat still real — because that is when the truth is still in the room. Every simulation program aspires to it. Almost none can deliver it, because reconstructing what actually happened takes hours of video review the facilitator does not have.
HOTWASH exists to make the name literal: the reconstruction is already done when the scene ends, because something was finally reading while it happened.
At any live instant, a solo sim operator must run the scenario — physiology console, event schedule — perform the counterpart — voice the patient, brief the confederate — and watch the trainee: the missed cue, the filled silence, the moment the training value actually lives. Three incompatible jobs, one human. A mind that is performing is, in that instant, not watching.
Programs compensate two ways, both expensive: a second staff member in the control room, or hours of after-the-fact video review per debrief. The recording rig captures everything and understands none of it — vitals on one system, audio on another, the facilitator's memory holding the timeline together. The field's own verdict on a generation of simulation hardware: the instrument records, but nothing in it reads.
HOTWASH takes exactly one of the three jobs — the watching — and refuses the other two by law.
Two things happened there that no current product can do. The operator got exactly one cue — from the deterministic floor, because an authored plant's response window was expiring — and the nine-second silence was measured and honored as a skill, not treated as dead air. When the scene ends, both are already on the tape, span-cited, waiting in the debrief.
HOTWASH rides FUSOR-1, the open resident-kernel substrate behind everything on this site: one persistent attention state, fed token-by-token as the world arrives, judging at completed thoughts — no poll, no turn, no send key. In this room, residency buys five specific things:
Every utterance, monitor event, and operator mark appends to one resident state the moment it exists. Nothing is ever re-read; there is no scan interval. Being current is not something the reader does — it is what the reader is.
The model already computes where a thought completes Measured — the reader fires its one question exactly there, mid-scene, which is where a human observer's judgment fires too.
Elapsed time enters the stream as world-state, so not speaking becomes a logged, duration-stamped decision with context. In communication training, the held silence is the skill — and turn-based tooling structurally cannot represent it.
The scenario's answer key — plants, expected-response windows — lives only in a deterministic floor the model never sees. Catch-grading is mechanical, and the reader's judgment stays honest, because the mind being asked "what matters here?" was never handed the answers.
A forming observation dies the instant the scene moves past it Measured — so the reader's attention tracks the room, not its own half-written thoughts.
The debrief artifact itself is a deterministic fold over the session tape — and a batch pipeline over the recording could build a similar artifact minutes later. So the residency claim rests on the live console and the silence record, and it races its own null: identical models, run after the fact, over the same recording. If the batch arm matches the live arm on operator outcomes, HOTWASH ships as an honest batch tool and this page will say so. No organ outlives its null — neither does this product.
Seconds after scene end, the cut renders: three time-aligned rails, a catch table, a silence table, and a debrief sheet of neutral, span-cited prompts for the facilitator. Every claim in it cites the tape; a claim that fails span-verification does not render.
Mechanical facts — catches, latencies, silences, protocol clocks — are stated as facts. Semantic observations ship as notes with citations, never scores, until blind concordance with expert scorers is demonstrated at a pre-registered bar. Assessment inflation is the fastest way to lose an education department's trust, and this product's entire posture is built not to earn it that way.
And here is that cut — from a real run. Not a mockup: a live HOTWASH watch-seat on a sepsis resuscitation of the kind a Laerdal SimMan or SimX VR console drives, replayed from its own tape. Every number is read from the tape at load; the tape is downloadable; and the rough edges are printed inside it, because this is P0.
A composite ICU sepsis resuscitation of the kind a Laerdal SimMan or
SimX VR console drives: a human facilitator runs the physiology (the [console]
monitor lane), a team works the patient, and — the third job no facilitator can also do while running
the other two — something watches the trainee. That watcher is HOTWASH. It never speaks to the
team; its only channel is a one-line cue to the operator's console, and its budget is a handful of cues
a scene. Below is a real run of it: every line, monitor event and silence perceived in order, every

And one rule running the opposite direction: the trainee owns their tape — the way a pilot owns a logbook. Sessions append to a portable, tamper-evident growth record that travels with the person, across programs and employers. In a consolidating industry, that record may be the most valuable thing this product produces.
HOTWASH's engine ratings are the FUSOR-1 substrate's bench ratings — measured, dated, receipted in the reference build's public runs ledger:

SUBSTRATE RATINGS, REFERENCE BENCH: ONE CONSUMER RTX GPU · 9B-CLASS OPEN WEIGHTS · WINDOWS. A 30-MINUTE SCENE IS A FEW THOUSAND TOKENS — THE WHOLE SESSION SITS RESIDENT WITH ROOM TO SPARE. HOTWASH-SPECIFIC NUMBERS DO NOT EXIST YET AND THIS PAGE WILL NOT PRETEND THEY DO. THE DESK-TUNED RESTRAINT FIGURE DOES NOT TRANSFER TO SIM-ROOM STREAMS BY ASSUMPTION — WHETHER IT TRANSFERS IS A PRE-REGISTERED BET (§ 07), AND UNTIL IT RESOLVES, EVERY SEMANTIC ORGAN RUNS IN SHADOW: JUDGING, LOGGING, SURFACING NOTHING. THE DETERMINISTIC FLOOR — PLANT WINDOWS, SILENCE METER, PROTOCOL CLOCKS — CARRIES THE LIVE CONSOLE AT LAUNCH, AND NEEDS NO TRUST IN ANY MODEL AT ALL.
| Name | The claim | It loses if |
|---|---|---|
| F-OPERATOR | With the console live, a solo operator misses fewer planted moments and recalls the scene better than solo-without, on matched scenarios | No effect — the live console is decoration, and the cut carries the product alone |
| F-LIVE>BATCH | The resident arm beats identical models run after the fact over the same recording, on operator-facing outcomes | The batch arm matches it — the residency claim dies for this vertical, in print |
| F-PLANT-GRADE | Mechanical catch-grading matches expert graders on authored plants (the closed board should make this near-exact) | Material disagreement — the scenario schema is underspecified and gets fixed before anything else does |
| F-SILENCE | Metered silence durations match ground-truth annotation within stated grain | They don't — the meter or the endpointing is wrong, and the flagship datum is unquotable |
| F-VISE-SIM | The deaf-vs-unlivable overlap measured on desk streams also exists on sim-room streams — i.e., a runtime dial does not suffice | A single dial separates them here — then no sim tune is trained, printed as a result, not a defeat |
| F-CONCORD | Semantic observations reach pre-registered concordance with blind expert scorers | They don't — scores stay off every surface permanently; notes-with-citations remain the ceiling |
| F-KEEPUP | Zero dropped percepts across a full session day; boundary-grain lag inside budget | A percept drops under a delta storm — the gate rule is violated and the build stops |
| F-CONTAINER | The consent gate, stop word, and custody rules survive a published self-attack battery | Any bypass path exists |
EVERY THRESHOLD IS FROZEN BEFORE THE EXPERIMENT THAT USES IT EXISTS. RESULTS PUBLISH EITHER WAY. THE NULL ARMS ARE NAMED: THE STATUS QUO (FACILITATOR + RAW VIDEO), THE BATCH PIPELINE, AND THE INCUMBENT AV-DEBRIEF PLATFORM AS DEPLOYED AT THE SITE.
No manikin integration required: diarized audio, operator marks, the silence meter, and the cut. The approach conversation, the disclosure, the difficult family — read and debriefed, with zero new hardware in the room.
Monitor events fused with the speech lanes on one timeline — the desat and the sentence that ignored it, finally in the same record. Vendor feeds arrive as adapters; the operator-mark floor works everywhere first.
N-way diarization, closed-loop-communication checks, and the coverage question no single observer can hold: who spoke, who was spoken to, and what fell between.
Referral-line drills, huddles, and role-played approach conversations — the highest-stakes communication curriculum in medicine, in the industry moment when demonstrable training is no longer optional. Sibling: IN-FLIGHT, when the counterpart itself goes synthetic.
The substrate is public, measured, and receipted. The architectural specification for HOTWASH is written. The build has not started. This page is the endpoint pitched honestly: what the finished instrument is, what it refuses to be, and the order in which it becomes real — sequenced so the bets die as early and as cheaply as possible.
The tape and the floor, no model. Diarized ASR, tick lane, silence meter, consent gate, session tape, the verifier, the cut v0. Already useful to a standardized-patient program.
The closed board live. Plant schema, mechanical grading, deterministic cues on the console, catch table in the cut — trustworthy at launch because no model judgment is in the loop.
The resident, in shadow. The reader ingests and judges everything, surfaces nothing, and the keep-up and fidelity gates run on real session days.
The valve. Facilitators review shadow observations in the cut, one key each — the labels that decide whether this vertical needs its own tuned disposition or a dial.
Live semantic cues at founder sites. F-OPERATOR and F-LIVE>BATCH run at two or three founding programs, half price, results published either way.
The tune if earned, the logbook formalized, the family unified — one authoring format and one growth record from human-run scenarios to the synthetic counterpart.
