What it does

sillage_sim

The model that makes a perfume a shape in time, and the only thing in Sillage that decides whether a formula is good.

A perfume here is never judged as a mixture. Every material has a volatility — a peak and a life — so a formula is a curve that rises, turns and falls, and the client's brief is a shape drawn on the same axes. Two formulas built from exactly the same five materials, in different doses, are different objects and get different answers.

What it holds
Sim.behaviour[id]peak, life, power, price, ceiling for all 36 catalogue materials
Sim.interactionsordered pairs — one material fixes, smothers or sours another
Sim.simulate(formula){ [id] = drops } → a Curve: 96 samples on the log time axis, per-family breakdown, the perfumer's notes on what happened
Sim.brief(n)the nth of six commissions — client, letter, target bands, budget, fee
Sim.judge(brief, curve)per-phase scores and the client's reply, stamped chef-d'œuvre, accepté or refusé

Identity and appearance live in sillage_core — name, family, vial, colour. Only behaviour lives here, keyed on the same id, so the organ, the ledger and the graph can never disagree about what a material is.

The units

Intensity is measured against Sim.reference: 1.0 is a full, properly dosed accord, and every brief's bands are written in those units. Curve.samples[i].norm is in them too, so the graph draws the player's line and the ghosted target on one scale. A drop is Sim.dropGrams of the batch, which is how a dose becomes a spend.

What the other slices call

  • composition — Sim.strike(formula) to get the curve, then emits strip:done; the sim judges and publishes verdict:given itself.
  • drydown — curve.samples for the ink line, sample.byFamily for the colour bands underneath, and Sim.targetBand(brief) for the ghosted shape printed under it.
  • economy — Sim.behaviour[id].price, Sim.dropGrams, Sim.costOf(formula).
  • presentation — Sim.stamp[outcome] for the wording, Sim.count() for the length of a career.

The six

  1. Mme Colette Vaugirard — an eau for the morning: bright, then gone.
  2. M. Étienne Barral, gantier — green, and it must survive the leather.
  3. Mlle Solange Aury — a rose that lasts from the curtain to supper.
  4. La Maison Duvelleroy — a chypre, base heavier than the heart.
  5. Le Comte de Rochefort — an evening thing, largest at midnight.
  6. Maison Perrachon — Sillage itself. The one worth the whole career.

Every one of them can be satisfied by more than one set of materials, and every one of them can be failed while using exactly the materials it asks for. That is the point: the brief states the shape, never the recipe.

Interface

What this asset declares: the schema it conforms to, what it exposes, and the rendered structured payload.

effectiveDrops(drops: number, ceiling: number) → number

Past the ceiling, more is very nearly not more: the extra drops compress into a square root. The cost of overdosing is not the material's own curve, it is what it does to everything standing beside it.

targetBand(brief: Brief) → void

The ghosted target as a list parallel to a curve's samples, so drydown can print the brief's shape under the player's line on one pass.

deliver(curve: Curve?) → Verdict

Judge whatever is on the blotter against the live brief, publish it, and say so once. Idempotent per curve: a slice that would rather call this itself than let the "strip:done" handler do it may, without the client replying twice.

strike(formula: { [string]: number }) → Curve

Convenience for composition: simulate, publish the curve, and hand it back.

haveBrief( ) → boolean

THE CAREER — six commissions, and what closes it A brief is a table carrying an `n`. Core.state.brief begins life as an EMPTY TABLE, which is truthy, so "is there a commission?" cannot be asked by testing the field itself.

advance( ) → string

The player has read the client's reply and put the sheet down. Either the next commission is waiting on the bench, or the career is over — because all six are delivered, or because the reputation is spent.

unbind( ) → void

bind( ) → void

Binding happens at module load, not only in start(), so a hot reload of this file leaves the loop closed rather than silently unjudged.

build(root: any) → void

Did the part work as advertised when consumers tried to drop it in. Separate from upvotes: those are taste; this is "did it function".
