Chairs disagreeing in writing is the output here, not a problem to be resolved. A blocks verdict opens an impact review; it does not kill anything, and no department holds a veto. Killing is Stage 5 arithmetic over verified claims. converged is not an approval either — the only approval in this repo is a human's, at Stage 6.

The round table

Each chair answers cold, from its own field, without reading the others' position files. What it states is a verdict, the conditions that would change it, and the requests it raises. A condition bound to a claim is a load-bearing statement, which is why it shows up in the register below.

What this opportunity rests on

The assumption register: the subset of claims that are load-bearing, each with who depends on it and what breaks if it is false. Rows arrive two ways — the front end writes one, or a chair binds a condition to a claim, which is the definition of load-bearing.

A1 claim 5: unconfirmed

If it is false: If refuted (the foundational Wake Forest patent US5636643 is not in fact expired): a live enforceable NPWT patent exists that must be checked against this device's mechanism before Legal & IP can move off abstains, and REQ-0006's landscape search has to add it as a candidate blocking patent rather than treating the foundational estate as closed. While it stays unconfirmed on a missing-credential basis, Factor 4 (FTO/IP) cannot move off blank from this line, and Legal's abstains cannot resolve even its cheapest half.

Depends on it: Legal & IP

A2 claim 6: unconfirmed

If it is false: Same mechanism as A1, plus a distinct second failure mode the file already flags: 5,645,081 may be the wrong Wake Forest family member entirely. If a human check shows it is not a Wake Forest NPWT patent, the foundational-estate half of the FTO opinion has no correct second citation and REQ-0006 has to establish the right number from scratch.

Depends on it: Legal & IP

A3 claim 7: unconfirmed

If it is false: Legal's own words: this "is the one that actually decides the question." If a landscape search finds a live Smith & Nephew PICO-family patent reading on canister-free/superabsorbent NPWT or dressing-interface chemistry, the "fast-follower has no regulatory delay" framing (claim 17) inverts into an FTO block — Route A (standalone sale) and Route B (licensing the drape/interface module) both lose the product they would sell or license.

Depends on it: Legal & IP, Commercial (REQ-0009)

A4 claim 12: unconfirmed

If it is false: Market Access's own text: even if C2/C3 resolve favorably, a sub-5% penetration rate bounds how much of the caseload the pet-insurance "offset" leg could ever reach. A materially different true figure resizes the population that needs the offset to afford treatment, feeding directly into Commercial's TAM (claims 13-15) and owner-willingness-to-pay (claim 21).

Depends on it: Market Access (unbound 4th condition), Commercial (context)

A5 claim 13: unconfirmed

If it is false: Commercial's own midpoint (~55k qualifying canine cases/yr) is a Generator estimate with no primary source. If the true caseload sits at or below the 30k floor, the revenue pool behind Routes A/C/D falls below a size worth building tooling and distribution for — the Scorer's note calls this "the hardest to close" component and possibly "permanently unconfirmable inside this pipeline."

Depends on it: Commercial (C1)

A6 claim 14: unconfirmed

If it is false: This price sets both the revenue-per-unit assumption and the ceiling Operations's C2/C6 and Commercial's C7 gross-margin conditions are tested against. If the achievable price is materially lower than $180-$320 — plausible if off-label PICO (claim 25) is cheaper — the COGS-plus-distributor-margin math (claim 27) may not close at any production volume, independent of whether the device can be built at all.

Depends on it: Commercial (C2)

A7 claim 15: unconfirmed

If it is false: The claim's own text concedes the 20-30% obtainable-share figure is "a modeling choice rather than a fact... an argument, not a lookup." If a survey or directory count shows actual specialty/referral concentration is materially lower, obtainable revenue in Routes A/C/D shrinks proportionally even with caseload (A5) and price (A6) both holding.

Depends on it: Commercial (C3)

A8 claim 16: unconfirmed

If it is false: "Patentable" is a prospective legal judgment; Legal's own corroborating check found ~10 new product-code-OMP clearances a year with ongoing drape-specific filing activity from incumbents through 2024. If a prior-art search shows the drape/interface space is already claimed or too crowded to file around, there is nothing to defend in Route A and nothing to license in Route B — Factor 5 (Moat) has no path off blank either way.

Depends on it: Legal & IP (C4), Commercial (REQ-0009, Route B)

A9 claim 18: unconfirmed

If it is false: This is the file's own strongest scored factor (Factor 7, draft 4/5) and the candidate's stated reason for being interesting at all — "no premarket submission, no IDE/IND-equivalent gate... first revenue plausibly at low-single-digit millions." Operations's own read is that the figure is "an under-scoped estimate." If it is confirmed under-scoped, that advantage shrinks or disappears.

Depends on it: Commercial (C8), Operations & NPI (context to C1/C2)

A10 claim 19: unconfirmed

If it is false: Commercial's own "What would change my mind": a negative survey answer here "alone is enough to kill Routes A and C in the existing business case without spending anything further on sizing." If vets will not switch from off-label human PICO, the standalone-hardware business has no customer at any price, caseload, or margin.

Depends on it: Commercial (C5)

A11 claim 21: unconfirmed

If it is false: If owners will not pay several hundred dollars out of pocket on top of the surgical bill, the cash-pay mechanism Market Access's entire verdict rests on has no payer at any price point Commercial has modeled, independent of caseload or margin.

Depends on it: Commercial (C4)

A12 claim 23: unconfirmed

If it is false: If a technician cannot reliably achieve a working seal without specialist training or adhesive spray, the labor/training cost this candidate's model assumes (technician-applied, home-dispensed) is understated, and the device may need a level of in-clinic supervision that undercuts the post-discharge, at-home commercial model it is built around.

Depends on it: Operations & NPI (C8)

A13 claim 26: unconfirmed

If it is false: If no major US veterinary distributor will carry an unbuilt SKU, Route A has no channel into the specialty/referral and equine practices the TAM assumes are reachable, regardless of demand or price.

Depends on it: Commercial (C6)

A14 claim 27: unconfirmed

If it is false: Both chairs bind this independently. Commercial's own business case states the whole Route A sales motion "is killed" if gross margin does not survive dressing COGS and the distributor's own cut — an explicit kill condition already written into the commercial file, not a soft risk.

Depends on it: Operations & NPI (C6), Commercial (C7)

A15 claim 28: unconfirmed

If it is false: Both chairs bind this independently; Technology and Clinical both separately name this as the file's highest-value verification target. The closest existing analog (PICO) is already documented "problematic in maintaining a vacuum" on an easier, clipped, non-weight-bearing surface, and separately unable to complete an open-wound seal study in horses "despite the use of many adjunctive adhesives" (PMID 30841889). If this candidate's drape cannot hold seal at -80 mmHg for 72 hours, the mechanism and the moat fail at the same point.

Depends on it: Technology & R&D (C1), Operations & NPI (C3)

A16 claim 29: unconfirmed

If it is false: Both chairs bind this independently. The closest species/procedure analog already shows this exact failure mode: a dog receiving NPWT over a skin graft (claim 38) had a bandage complication after NPWT cessation that caused partial graft loss.

Depends on it: Technology & R&D (C2), Operations & NPI (C4)

A17 claim 30: unconfirmed

If it is false: Technology names this "the single highest-value item to watch" of its four feasibility claims. The AJVR analog (claim 9) already reports this exact failure mode — "self-limiting skin irritation... hampering attainment of negative pressure" — on a different adhesive/foam interface; if it recurs here, the device cannot hold therapeutic pressure at home, defeating the whole post-discharge value proposition.

Depends on it: Technology & R&D (C3)

A18 claim 31: unconfirmed

If it is false: If sterile packaging and dressing tooling cannot be validated to ISO 11607 absent premarket review, the "no IND/IDE-equivalent required" cost advantage (claim 18/Factor 7) is real on the regulatory side and blocked on the manufacturing side — the device cannot ship regardless of what the market or clinical evidence says.

Depends on it: Operations & NPI (C5)

A19 claim 41: unverified

If it is false: If first revenue is not reachable within a calendar consistent with the low-single-digit-millions capital figure, Factor 7's "cheap and fast" thesis loses the "fast" half even if the dollar figure holds.

Depends on it: Commercial (C8, calendar half)

A20 claim 46: unverified

If it is false: Clinical's own bar for moving off conditional toward supports; Technology names the same study as the cheapest artifact that would move its own C1/C2/C4 together. If the interface fails to avoid the seal-failure mode already documented for PICO in these species, Clinical states this is one of two findings that "would move this verdict toward blocks."

Depends on it: Clinical & Scientific (C1), Technology & R&D (adopts as its own basis)

A21 claim 47: unverified

If it is false: The only controlled comparison that already exists at this candidate's exact site (equine distal limb, claim 20) found NPWT worse than calcium alginate early and no long-term advantage. If a prospective study against this candidate's own device does not show a favorable effect versus standard of care, Clinical has no basis to move off conditional, and per Clinical's pivot note this must resolve favorably in horses specifically before the position can move past conditional for any indication keeping the equine segment.

Depends on it: Clinical & Scientific (C2)

A22 claim 48: unverified

If it is false: The CFR reads (807.81/807.20/807.65) have already returned verified once, quoted inside claim 1's notes, but never on their own claim line. If this does not verify cleanly when run cold on its own line, Regulatory's stated "cheapest move available today" toward supports fails, and the premarket-notification conclusion stays anchored only inside claim 1's attribution notes, which can never verify by design.

Depends on it: Regulatory (C1)

A23 claim 49: unverified

If it is false: Same mechanism as A22 for 814.1(a)/PMA scope. If it does not verify on its own line, the PMA-exemption conclusion has the same unresolved anchoring problem.

Depends on it: Regulatory (C2)

A24 claim 50: unverified

If it is false: Regulatory is explicit: "no premarket review" is not "no regulatory exposure." If post-market misbranding/adulteration authority is confirmed to reach this device's therapeutic-effect language ("reduce edema, promote granulation, and stabilize skin grafts"), that labeling becomes a live enforcement surface — Regulatory warns this must not be read in anyone's head as "label whatever the mechanism plausibly does." Commercial's C8 (claim 18) also inherits this indirectly via claim 1/3.

Depends on it: Regulatory (C3)

A25 claim 51: unverified

If it is false: Technology names this "the integration-risk condition": the drape and the chew-resistant shell have opposing material-property pulls. If the combined assembly fails a bench test even when each component passes alone, C1 and C2 passing independently would be misleading — a working drape and a working shell do not guarantee a working device.

Depends on it: Technology & R&D (C4)

A26 claim 52: unverified

If it is false: If battery/electrical-safety qualification and drape biocompatibility/skin-irritation qualification are not already priced into claim 18, Operations states this is "additional NPI cost and schedule items beyond the two named in claim 18" — a confirmed gap directly under-scopes the capital figure Commercial's C8 and Factor 7 both depend on.

Depends on it: Operations & NPI (C1)

A27 claim 53: unverified

If it is false: This is Market Access's structural premise for the whole reimbursement-side verdict — no HCPCS/CPT/Medicare/Medicaid mechanism can ever apply to an exclusively-veterinary device. If a human read of 42 U.S.C. § 1395c and 42 CFR 400.202 against the HCPCS code-request process shows this is not in fact categorical, Market Access's "revenue is cash-pay, full stop" framing has to be redone, potentially opening a coding/coverage path the commercial model does not contemplate.

Depends on it: Market Access (C1)

A28 claim 54: unverified

If it is false: If the capital estimate funds only pilot-volume tooling that would need re-tooling before any commercial-volume order could be filled, "low-single-digit-millions to first revenue" is not the same figure as "low-single-digit-millions to sustainable $180-$320 unit economics" — Operations's own human check requires a second cost-of-goods build-up at 10x volume before treating claim 18 as a plan.

Depends on it: Operations & NPI (C2)

A29 claim 55: unverified

If it is false: Market Access states this is what converts "optionally offset by pet insurance" from "a hopeful clause" into "a bounded number." If pet insurers in fact adjudicate by matching a procedure code (contrary to this condition), the absence of a CMS code categorically blocks the insurance-offset leg rather than merely bounding it.

Depends on it: Market Access (C2)

A30 claim 56: unverified

If it is false: If a major US pet insurer's policy language does categorically exclude NPWT or wound-care adjunct devices, the insurance-offset leg is foreclosed regardless of penetration rate or adjudication mechanism (claims 12, 55) — Market Access names this as one of its two load-bearing unknowns, alongside C2.

Depends on it: Market Access (C3)

A31 claim 57: unverified

If it is false: Operations names this "a concentration risk worth naming at concept stage." If the drape depends on a single adhesive/coating formulation and a single qualified converter with no second source anywhere in the file, a single supplier disruption stops the entire product's supply chain — a different and more fragile risk than the cost questions in C1/C2/C6.

Depends on it: Operations & NPI (C7)

A32 claim 58: unverified

If it is false: If claim 18's capital estimate excludes ground-up bench/in-vivo development spend for the drape and interface (both unbuilt, both the file's own stated moat), the "cheap and fast" Factor 7 thesis is missing an entire cost bucket upstream of the tooling and packaging validation it does name — compounds with A9 (claim 18) and A26 (claim 52).

Depends on it: Operations & NPI (C9)

A33 claim 59: unverified

If it is false: Raised answering REQ-0008: the closest canister-free analog (Smith & Nephew PICO) has its own recall history naming a sealing/port failure adjacent to a dressing connector. If this candidate's pump-to-dressing joint repeats that failure mode, the device fails at the mechanical connector even if the drape's adhesive chemistry independently holds seal — a second, independent failure point beyond A15-A17.

Depends on it: Technology & R&D (C5)

A34 claim 60: unverified

If it is false: Raised answering REQ-0014: if no design-input spec (battery chemistry/capacity, electrical-safety standard, duty cycle, pressure-control tolerance) exists for the pump subassembly independent of the dressing/drape system, the pump stays an unspecified commodity item and Operations's capital estimate (claim 18/52) cannot be priced against a named standard.

Depends on it: Technology & R&D (C6)

A35 claim 61: unverified

If it is false: Raised answering REQ-0013: Commercial's own reading is that claim 18's capital estimate funds pilot-volume tooling only, not the commercial-scale tooling ordinarily needed to reach the $180-$320 unit economics claim 14 assumes — a second, larger capital raise may be needed before the price claim is reachable at all, independent of what REQ-0018's COGS benchmarking found.

Depends on it: Commercial (C9)

A36 claim 62: unverified

If it is false: Raised answering REQ-0011: no single study in the file yet tests both this candidate's site (distal limb, claim 20) and its form factor (canister-free, claim 9) at once. If the equine study's device is confirmed conventional-canistered rather than canister-free, claim 20's unfavorable finding does not yet establish that the canister-free form factor underperforms at this site — a gap in, not a resolution of, Clinical's conditional verdict.

Depends on it: Clinical & Scientific (C4)

A37 claim 63: unverified

If it is false: Raised answering REQ-0010: the promoted CPG/FD&C Act report found 21 U.S.C. §§ 351/352 apply their misbranding/adulteration grounds to "a drug or device" with no human-use qualifier, unlike the premarket sections' express human-use limitation. If a human read of the full statutory text and FDA's enforcement posture confirms this reading, post-market labeling exposure over the candidate's therapeutic-effect language ("reduce edema, promote granulation, stabilize skin grafts") is live regardless of the confirmed premarket exemption — bears on Commercial's cash-pay marketing latitude (claim 18/Factor 7).

Depends on it: Regulatory (C4)

A38 claim 64: unverified

If it is false: Raised as the actual settling artifact for A1-A3: the promoted patent-landscape report found three live Smith & Nephew canister-free NPWT patents (US9,061,095 B2, US11,395,870 B2, US12,453,658 B2) whose retrieved independent claims recite no species or human-only limitation. This is adverse, not yet dispositive — a public keyword search is not a claim-chart opinion. If a professional claim-chart comparison finds literal or doctrine-of-equivalents infringement with no available design-around, Route A (standalone sale) and Route B (licensing) both lose the product they would sell or license, the exact failure mode A3 named.

Depends on it: Legal & IP (C5)

What failed, and what it cost

When a registered statement comes back refuted or unconfirmed, an impact review fires. It has exactly three available outcomes and check_loop.py refuses a record that invents a fourth.

IR-1 claims 5 and 6 came back unconfirmed (missing credential) — 2026-09-13 commission
  • The statement: [claim 5: unconfirmed] — US Patent 5,636,643 (Argenta/Morykwas, Wake Forest, filed 1993-03-09) has expired. [claim 6: unconfirmed] — US Patent 5,645,081, the claimed companion Wake Forest patent, has also expired.

Nothing was looked up in either direction on either patent — this is a missing-credential gap, not a finding about either patent's status.
  • Who depended on it: A1, A2 — Legal & IP, whose abstains verdict names configuring these credentials as "the cheapest single move" and states plainly it "would not move this verdict off abstains on its own."
  • What it costs: without it, the foundational half of the FTO opinion stays unconfirmed indefinitely, and the file's own caveat that 5,645,081 "may be the wrong family member" stays fully open — a second, distinct failure mode layered on top of the credential gap.
  • Outcome: commission
  • Because: this is a same-day, no-cost tooling fix already named by Legal & IP — configure EPO_OPS_KEY/EPO_OPS_SECRET, then re-run python3 -m connectors patent US5636643 and, once a human confirms the correct family member, US5645081. It is queued for the Verifier's next pass rather than a cross-department research question, so no ledger request was raised against it — it needs configuration, not research.
IR-2 claim 7 unsearched — 2026-09-13 commission
  • The statement: [claim 7: unconfirmed] — FTO risk concentrates in live patents covering canister-free/superabsorbent single-use NPWT (Smith & Nephew PICO family) and dressing- interface chemistry, not in the expired foundational estate.
  • What the check found: no run was possible — the patent connector takes a single patent ID and runs no landscape or assignee search, and this claim names no patent number. Legal & IP's own corroborating check (a 510(k) landscape pull, not a patent search) found 111 clearances under product code OMP over ~10.7 years, with ongoing drape-specific filing activity from incumbents through 2024 — a marketing-authorization record, not a patent finding, and Legal is explicit it should not be read as one.
  • Who depended on it: A3 — Legal & IP (abstains, C3) and Commercial (REQ-0009, which asks whether this claim blocks Route A's moat or Route B's licensing thesis).
  • What it costs: per Legal & IP's own verdict, this is "the one that actually decides the question" of freedom to operate; a live blocking patent would take the product away from both Route A (standalone sale) and Route B (licensing the drape/interface module).
  • Outcome: commission
  • Because: REQ-0006 (legal-ip → research) is already open and asks exactly this — a landscape search on CPC A61M1/90-A61M1/98 against the named assignees, with any resulting numbers run back through the patent connector once found.
IR-3 claim 16 unsearched — 2026-09-13 commission
  • The statement: [claim 16: unconfirmed] — the fur-compatible adhesive drape chemistry and chew/bandage-resistant limb interface are both patentable and both species-specific.
  • What the check found: not checkable — "patentable" is a prospective legal judgment no connector can return, and nothing is filed or built to search prior art around.
  • Who depended on it: A8 — Legal & IP (C4) and, indirectly, Commercial's Route B licensing thesis (REQ-0009).
  • What it costs: if this space is already claimed or too crowded to file around, there is nothing for Route A to defend and nothing for Route B to license — Factor 5 (Moat) has no path off blank either way.
  • Outcome: commission
  • Because: REQ-0007 (legal-ip → research) is already open and asks exactly this — a prior-art/patentability search on animal-skin-compatible adhesive drape chemistry and limb-conforming NPWT interfaces.
IR-4 claim 12 structurally unconfirmable — 2026-09-13 commission
  • The statement: [claim 12: unconfirmed] — pet insurance penetration in the US is under 5% of owned dogs.
  • What the check found: the market connector returned unverifiable by design — no free, authoritative, machine-queryable source; the named source (NAPHIA) is licensed and must be human-attached.
  • Who depended on it: A4 — Market Access, which treats this claim as an unbound fourth condition on its own verdict.
  • What it costs: if the true figure differs materially, the population the pet-insurance offset leg of the revenue model could ever reach changes, which bears directly on Commercial's TAM (claims 13-15) and owner-willingness-to-pay (claim 21) conditions.
  • Outcome: commission
  • Because: unconfirmed here is a licensing gap in the connector surface, not a finding — the underlying number is a purchasable, well-defined statistic. No chair had raised a request against it (Market Access explicitly declined to re-bind it), so Front End raised REQ-0015 (front-end → research) while opening this loop record.
IR-5 claims 13, 14 and 15 structurally unconfirmable — 2026-09-13 commission
  • The statement: [claim 13: unconfirmed] — annual US qualifying canine caseload 30,000-80,000. [claim 14: unconfirmed] — net unit price $180-$320. `[claim 15: unconfirmed]` — obtainable share 20-30%.
  • What the check found: all three returned unverifiable from market by design (no free, authoritative, machine-queryable source), and the usual decomposition route (procedures) is Medicare fee-for-service and structurally blind to animal procedures.
  • Who depended on it: A5, A6, A7 — Commercial (C1, C2, C3), and Operations & NPI's C2 (claim 54) and C6 (claim 27), both of which test the $180-$320 price (claim 14) against a cost-of-goods build-up.
  • What it costs: this is the entire TAM chain — Commercial's own midpoint math (~$3-4M/yr initial obtainable US canine revenue) rests on all three, and the file's own Scorer's note calls claim 13 "the hardest to close" and possibly "permanently unconfirmable inside this pipeline."
  • Outcome: commission
  • Because: these are purchasable, well-defined figures (veterinary epidemiology and pricing data), not findings the connector surface refutes — the textbook unconfirmed-is-a-gap-in-the-check case the protocol names. No request existed for any of the three; Front End raised REQ-0016 (front-end → research) while opening this loop record.
IR-6 claims 19, 21 and 26 unconfirmable, stakeholder-future claims — 2026-09-13 commission
  • The statement: [claim 19: unconfirmed] — vets will choose a purpose-built unit over continuing to buy human PICO off-label. [claim 21: unconfirmed] — owners will pay several hundred dollars out of pocket. [claim 26: unconfirmed] — a major US veterinary distributor will carry the SKU.
  • What the check found: all three returned unverifiable from adoption by design — stakeholder-future claims with no free, authoritative source; the connector's own instruction not to substitute a model's estimate of stakeholder behaviour was followed, and nothing was fabricated in its place.
  • Who depended on it: A10, A11, A13 — Commercial (C5, C4, C6 respectively).
  • What it costs: Commercial's own "What would change my mind" section states a negative survey answer on claim 19 alone "is enough to kill Routes A and C in the existing business case without spending anything further on sizing" — the cheapest and most consequential unresolved question in the file by Commercial's own account.
  • Outcome: commission
  • Because: claims 19 and 21 are already named in REQ-0011 (commercial → clinical) as bearing on the willingness-to-pay conditions, and Commercial's own position names the settling artifact for claim 19 directly (a structured ACVS/AAEP surgeon survey). Claim 26 (distributor listing) is a distinct question REQ-0011 does not reach; Front End raised REQ-0017 (front-end → research) for it while opening this loop record.
IR-7 claim 27 unconfirmable — 2026-09-13 commission
  • The statement: [claim 27: unconfirmed] — gross margin at the proposed practice price supports a distributor sales motion after dressing cost of goods and sterile packaging validation.
  • What the check found: not checkable by any connector — a financial-modeling claim (COGS, packaging-validation cost, distributor margin stack) with no registry or market API behind any of its inputs.
  • Who depended on it: A14 — Operations & NPI (C6) and Commercial (C7), bound independently by both chairs.
  • What it costs: Commercial's own business case states plainly that the whole Route A sales motion "is killed" if gross margin does not survive COGS and the distributor's cut — an explicit kill condition already written into the commercial file, not a soft risk.
  • Outcome: commission
  • Because: REQ-0013 (operations-npi → commercial) already tests whether the $180-$320 price and the claim-18 capital estimate describe the same production volume, but does not itself price COGS or the distributor margin stack; Front End raised REQ-0018 (front-end → research) for the itemized cost-of-goods and margin-schedule question while opening this loop record.
IR-8 claims 23, 28, 29, 30 and 31 — unbuilt-hardware and human-factors claims — 2026-09-13 commission
  • The statement: [claim 28: unconfirmed] — the drape holds seal at ~-80 mmHg for 72 hours. [claim 29: unconfirmed] — the interface survives normal animal behaviour and bandaging. [claim 30: unconfirmed] — irritation stays below the threshold that defeats the vacuum. [claim 31: unconfirmed] — sterile packaging/tooling can be validated absent premarket review. [claim 23: unconfirmed] — a technician can apply the drape and achieve a reliable seal without specialist training.
  • What the check found: none checkable by any connector — the drape and interface do not exist as built hardware, and no registry, regulatory, or literature connector reaches unbuilt-hardware performance or an unrun usability study. The closest existing evidence is negative-direction and on a different interface: [claim 9: unconfirmed] reports "self-limiting skin irritation in all dogs hampering attainment of negative pressure," and [claim 38: unconfirmed] reports a bandage-layer complication causing partial graft loss in the closest species/procedure analog.
  • Who depended on it: A15, A16, A17, A18, A12 — Technology & R&D (C1, C2, C3), which names claim 28 as "the highest-value verification target" jointly with Clinical, and Operations & NPI (C3, C4, C5, C8), which reads these as "the design inputs the whole NPI plan rests on."
  • What it costs: the core engineering bet of the candidate. Technology's own verdict states the moat half of the device "exist[s], right now, only as an intention"; if the combined assembly cannot hold seal, survive normal use, and stay below the irritation threshold, the product has no engineering path to the home-care indication it is built around, regardless of market size, price, or regulatory posture.
  • Outcome: commission
  • Because: this is bench-and-in-vivo work, not a research lookup. Technology names the exact artifact that would settle it — "a single bench report showing a combined drape+interface assembly holding -80 mmHg on a furred, articulating limb model through a simulated wear/chew/re-bandage cycle" — and Operations names the corresponding usability study for claim 23. Neither is a cross-department question a research request could answer; both are named, buildable next steps outside this pipeline's connector surface entirely, the same shape as Clinical's own bound conditions (claims 46/47) below.
IR-9 claim 18 unconfirmed, capital-intensity — 2026-09-13 commission
  • The statement: [claim 18: unconfirmed] — first revenue is achievable for low-single-digit millions, dominated by dressing tooling, sterile packaging validation, and one or two prospective clinical case series, with no IND/IDE-equivalent required.
  • What the check found: not checkable — no connector prices tooling, ISO 11607 validation, or a study protocol, and the "no IND/IDE-equivalent required" half inherits directly from claim 1, itself unconfirmed. Operations & NPI's own reading (context, not a bound claim on this row) is that claim 18 "names a narrower cost bucket... than the device it is pricing."
  • Who depended on it: A9 — Commercial (C8), and Operations & NPI's C1/C2 (bound separately to claims 52 and 54), which test this claim's scope and production-volume assumptions respectively.
  • What it costs: this is the file's own strongest scored factor (Factor 7, draft 4/5) and the candidate's stated reason for being interesting at all; if it is under-scoped, that advantage shrinks or disappears.
  • Outcome: commission
  • Because: three open requests already jointly commission this claim from three angles — REQ-0010 (commercial → regulatory, whether the claim-1 premarket-review premise holds), REQ-0012 (technology → operations-npi, whether the estimate prices the drape/interface development spend), and REQ-0013 (operations-npi → commercial, whether the price and capital figures describe the same production volume). No further commissioning is needed.

How the shape changed

The opportunity is still in its original shape — no pivot has been recorded. That is not the same as being confirmed; it means no failed statement has yet forced a change of shape.

Open questions between departments

Any department may ask any other what it cannot answer itself. The answer must name an artifact that exists — a research report, a position, a dossier — never a summary.
