Heavy-Appliance Mobility
Nishi vs the field — every Nishi cell is measured against real organ source at emit time; each gap names the watch contract that will close it.
Nishi glide-base plus stair-module appliance mover (designed from the first bit up) vs Airsled air film and Escalera StairCat and PowerMate motorized climbers and tracked crawler dollies -- Aug-2026 field
Layer 1 · Executive
Where we are. MEASURED 2026-08-19: no Nishi hardware exists in this domain. What IS measured in tree: the product decomposer (pd_parse), the sovereign STL-to-G-code slicer (printed fixtures), the landed-cost corridor engine (lc_calc) and the sourcing-mix reshore pricer (sp_mix) -- the design-to-business substrate every physical product inherits. The Aug-2026 field is mapped and mirrored: air film for floors, dealer-priced motorized climbers at 1200 to 1,500 lb, consumer tracked crawlers in the 330 lb class.
Where we need to go. OPERATOR ASK (2026-08-19): easy-glide wheels for heavy appliances that can even go up stairs. The wedge no incumbent spans: a PERMANENT under-appliance glide base that mates with a detachable stair-climb module. Ship the design organs first and prove them by gates, steel second -- the physics and costing organs are reusable across every physical product that follows.
The unit. 1 u = one measured session-leg (organ plus gate plus live flip), the mangagen and comms calibration.
Cost to a proven design engine: 4 u. AM1 stair envelope, AM2 load margins, AM3 tipover, AM4 brake energy -- each a gated organ with a pre-declared refusal rule; pure organ work on the existing substrate.
Cost to a priced BOM and a buy-vs-build verdict: 2 u more. AM5 composes lc_calc corridors and sp_mix reshore paths over the real part list; the biz table below regenerates from it. 6 u cumulative.
Cost to a field-proven first article: 4 u more plus hardware. AM6 glide-base pack and AM7 field gate; cash exposure before steel is one crawler teardown unit [crawler] and printed fixture stock. 10 u cumulative.
Research bar. PowerMate automatic braking, the field safety bar is measured on operator-release lock behaviour documented across the powered-climber field. Theirs: the load locks in place the instant the operator releases the controls [@powermate]. Ours: our AM4 contract adopts lock-on-release as a REFUSAL rule -- a design that cannot lock does not pass its gate.
Business case
| Axis | Position | Figures | Decision |
|---|---|---|---|
| Investment | The design-engine leg is pure organ work on the existing substrate; hardware spend begins at one consumer crawler teardown unit in the 330 lb class [crawler] plus printed fixtures | estimated 10 u to a field-proven article; cash before steel is bounded by the teardown unit and fixture stock | fund the organ leg now, gate hardware spend on the M1 BOM verdict |
| Market | Three incumbent formats and none spans the ask: air film for finished floors [airsled], dealer-channel motorized climbers at 1200 to 1,500 lb [escalera] [powermate] [liftkar], consumer tracked crawlers [crawler] | the permanent glide base plus stair module covers a gap no format serves | position retrofit-first: the base addresses every appliance owner, the module addresses movers and property managers |
| Opportunity cost | The same 10 u could extend an existing revenue lane; the offset is that AM1-AM5 are reusable physics and costing organs every later physical product inherits | the first product pays the substrate tax for the whole physical lane | charge the substrate to the physical-products program, not to this product alone |
| Go to market | Movers, appliance dealers and property managers buy outcomes, not tools; the incumbent climbers sell through dealers and rentals [liftkar] | house-call service pricing per move is the proven channel shape | start with the service wedge to fund the product wedge; the GTM facade ranks channels once cotton-style channel rows are admitted |
| Buy vs build | Air film, powered climbers and crawlers are mature BUYS for internal moving needs today [airsled] [powermate] | nothing on the market is a permanent under-appliance base with a stair module | buy one crawler for teardown reference; build only the wedge |

Layer 3 · Engineering
How this is scored. Every Nishi mark is measured: the generator reads the real organ source on disk and requires the implementing symbol to exist (no self-grading). A watching tag names the organ and symbol contracted to close a gap — the mark flips itself on the next compare beat when that workstream ships, and the
comparewatch- plane row flips with it. The flip is necessary, not sufficient: it proves the symbol exists, never that the capability is good. The bar is the rung's pre-declared done-rule, proven by its gate — a symbol shipped without the behaviour behind it is a defect, and the flip is exactly what makes that defect visible instead of quiet. Competitor marks record documented capability presence — presence, not depth or scale. Adoption is measured too: every measured row carries where its organ stands on the estate's ladder (source → built → promoted → registered → invoked; libraries by importer reach minus validation importers; gates by the execution surfaces that run them). A row is fully adopted only at the top of its ladder; anything short is tagged partial with the exact remedy, so a build nobody promoted can no longer read as shipped. Census stamps: importers asof 1787849099, gate census asof 1787855507 (unix seconds; -1 = census absent).Capability matrix — measured against source

On these two registers. Rows are declared in the domain's plan file and carry the debt id, which is the join key back to the sovereign debt plane — that plane, not this page, is the authority on state. Reconciling them automatically (the regen reading the plane and refreshing these rows) is a named, owed rung; until it lands, treat an id here as a pointer to look up, not a status to trust.
Honest verdict. The Aug-2026 field splits into three formats and none spans the whole ask. Air-film movers glide heavy appliances over finished floors on a micro-thin air cushion -- the force to move the load drops to roughly 1 percent of its weight [@airsled] -- but cannot touch a stair. Motorized stair climbers own the stairs: Escalera StairCat lifts to 1200 lb on tempered-aluminum frames [@escalera], the PowerMate M-1 class reaches 1,500 lb with an automatic brake that locks the load the instant the operator releases the controls [@powermate], and the Magliner-distributed Liftkar line covers the ergonomic mid-range [@liftkar] -- all dealer-channel, none of which stays under the appliance. Tracked crawler dollies in the 330 lb class automate the climb at consumer prices on rubber non-marking tracks [@crawler]. The Nishi wedge no incumbent spans: a PERMANENT under-appliance glide base that mates with a detachable stair-climb module, engineered against the published stair envelope (OSHA 1910.25 fixes riser and tread geometry for general-industry stairs, risers capped at 9.5 inches [@oshastairs]), with tipover, load-margin and descent-brake models proven as gated organs BEFORE steel is cut, and the BOM priced through the estate landed-cost and sourcing engines.
