Important rules carry a source type. Heuristic is not standard. Methodology is not a measurement. Conflicting or incomplete stays labelled.
Primary walk ≥ 36 inches
CurrentheuristicmediumLab uses 36 inches as the fail line for a primary walk with the door open, and 42 inches as preferred. This is a professional planning heuristic. It is not a certificate that a dwelling meets code.
Residential circulation heuristic informed by IRC egress widths and ADA accessible-route minima · source · checked 2026-08-27 · vlab.clearance.v1
Hall, kitchen aisle (42"), and bed-side (24") use the same family of heuristics. Unverified when dimensions are unknown.
- Whether a given door is a required egress in this dwelling is often unknown and is never guessed.
Pulse friction 0–100 (higher = worse)
Currentinstrument-contracthighPulse rates six human conditions. Lab ranks known scores high-to-low and ties-breaks movement → function → light → comfort → reset → personality. A missing score does not rank and is not treated as zero.
Room Pulse method (RFD-RP-001) mapped by Lab · source · checked 2026-08-27 · vpulse.diagnosis.v1 / envelope 1.1.0
Legacy Pulse 0/1/2 ratings map to friction 100/50/0. Quick Start does not invent scores.
Safety holds until a professional clears it
VerifiedmethodologyhighStructural, electrical, gas, moisture, and the way out are outside Lab authority when they fail. A watch is visible and does not lock. Unknown is unknown — Lab does not invent a fail or an all-clear.
Room for Drama methodology — Lab will not sequence atmosphere over a named safety concern · checked 2026-08-27 · vlab.gate.v1
Professional-boundary status from Pulse is mapped so a named safety concern cannot be skipped.
Six layers, bottom to top
CurrentmethodologyhighArchitecture is given. Furniture, light, planting, pattern, and soft objects stack on it. A layer that does not reduce the primary friction is held or refused.
Room for Drama spatial method · source · checked 2026-08-27 · vlab.layers.v1
Atmosphere biases the upper stack; it never unlocks architecture.
One change at a time, seven days
CurrentmethodologymediumA reversible test is information. Two simultaneous changes make drift unreadable. Check the same Pulse questions after seven days. If the primary did not move, put the change back.
Room Lab 7-day test · checked 2026-08-27 · vlab.experiment.v1
Duration is a test window, not a clinical finding.
Pulse → Lab (stays in this browser)
Verifiedinstrument-contracthighPulse places the diagnosis in this browser (it never leaves the tab). Lab shows the plate before loading. Unknowns stay unknowns.

applicationId RFD-RP-001. Lab maps; it does not re-diagnose.
Spec Desk: published measurements only
CurrentmethodologyhighWidth, depth, height, material, price, lead time, and care are captured from the publisher or entered by the occupant. A missing number stays unknown. Catalog seed is IKEA US pages captured 2026-08-27. Fit tests scale, circulation (36" heuristic), visual mass, declared jobs, and whether the layer reduces the primary Pulse friction. A picture is not a measurement; Concept View is later and labelled concept.
Room for Drama methodology — a product is tested against a measured room, never against a mood · source · checked 2026-08-27 · vlab.spec.v1
URL fetch is SSRF-safe https only. Published product pages are preferred. IKEA measurement lines are a fallback. Prices are a snapshot, not a live quote.
- Lead time is ZIP- and stock-dependent and is never invented as a single number.
- Whether a given door is required egress remains unknown unless Pulse marked it as needing professional review.
Budget: commitments first, atmosphere last
CurrentmethodologymediumA named budget is architecture. Known commitments are taken first. A reserve is held as unknown-cost, not leftover paint. Remaining money is sequenced free → test → commit → lock. Pulse ranking, whether professional review is required, and measured-room area score four profiles (Balanced, Atmosphere-forward, Function-first, Lean). Atmosphere-forward waits while movement is the primary problem or a named safety concern is on. An unnamed budget is unknown, not zero. Spec Desk published prices are tested against remaining money; they are snapshots, not quotes. Thresholds are heuristics.
Room for Drama methodology, theory shared with Tangled Thistle Budget-to-Atmosphere, rewritten for rooms · source · checked 2026-08-27 · vlab.budget.v1 / lab.budget.intel.v1
Event categories from Budget-to-Atmosphere (venue, food, guests) are not used. This is a planning model, not a specification and not a code opinion.
- Landed cost (freight, tax, haul-away) is asked as a hidden-cost prompt and is never invented as a number.
- Per-square-foot bands are planning heuristics, not market comps.
