Runway Is Not Survival
Orville Davis·Author
Runway is how long operations can continue at the current net burn before cash is exhausted: cash divided by burn rate, with explicit assumptions. Survival is whether the business can keep meeting obligations (payroll, vendors, debt service, plant continuity) through the next decision horizon — not just whether a runway number is positive. A long runway can still miss survival. A short runway can still survive a decision horizon.
Runway is not survival. Runway is how long operations can continue at the current net burn before cash is exhausted. That duration is cash divided by burn rate, with explicit assumptions. Survival is whether the business can keep meeting obligations (payroll, vendors, debt service, plant continuity) through the next decision horizon — not just whether a runway number is positive. A long runway can still miss survival if burn assumptions are wrong, receivables never convert, a single customer concentration collapses, or critical capacity (people, permits, plant) fails before cash does. A short runway can still survive a decision horizon if cash inflows are contracted, burn is cuttable on a named date, or a financing path is already closed — none of which the runway formula itself proves. Treating a runway figure as survival records a duration as a claim that obligations will be met through the next decision horizon nobody has shown, under the honesty and verification boundary. Sync may surface a runway figure or a survival note beside Evidence, Verification, and the closed outcome. Surfacing is still a read. A long runway with wrong burn assumptions, receivables that never convert, a single customer concentration that collapses, or critical capacity that fails before cash does leaves survival unmet. A short runway with contracted inflows, burn cuttable on a named date, or a financing path already closed can still meet obligations through that horizon. Direct plant execute stays off. CMMS write-back is not a live product path. Billing write-back is not a live product path. Sync does not book revenue. Sync does not recognize revenue. Sync does not measure ARR. Sync does not measure ARR for the customer. Sync does not measure cash. Sync does not measure cash for the customer. Sync does not measure runway. Sync does not measure runway for the customer. Sync does not measure survival. Sync does not measure survival for the customer. Sync does not collect cash. Sync does not attribute a change in cash, risk, or capacity. Sync does not execute plant work.
A runway figure looks like the close of the survival question. The duration is named. Someone reads a positive number and treats the business as able to keep meeting obligations through the next decision horizon. The figure did none of that by itself. It answered how long operations can continue at the current net burn before cash is exhausted, when the figure is that runway and the assumptions are named. It did not state whether payroll, vendors, debt service, and plant continuity can be met through that horizon. It did not show that the burn assumptions hold. It did not show that receivables convert. It did not show that a single customer concentration holds. It did not show that critical capacity (people, permits, plant) lasts until cash does.
The stack is the same kind of refusal this series keeps. Closure is not cash. Cash is not margin. Margin is not profit. Profit is not value. Value is not outcome. Outcome is not impact. Impact is not revenue. Revenue is not ARR. ARR is not cash. Cash is not runway. Runway is not survival. Each word can be true in its own place. None of the earlier words fills the last one. A closed work order, cash collected, a unit remainder, a profit figure, a measured outcome, an attributed change, a recognized sale, an annualized contract, a spendable balance, and a duration at the current net burn are activity, money, accounting, a recorded result, a claim about that result, a period booking, a recurring contract, a balance, and a calculated duration. Runway is how long operations can continue at the current net burn before cash is exhausted. Survival is whether the business can keep meeting obligations through the next decision horizon. A runway number is not that claim.
Sync keeps that split on the signed-in Decision Case. A signed-in user completes the case in a fixed order: Question, Evidence, Recommendation, Human decision, Action, Verification, and Learning. Orville Davis states that order in Field Manual v0. The manuals index lives at /manuals. This essay is why runway cannot be read as survival. The Evidence chapter may hold a runway figure, a note that obligations were named, or a note that someone else stated either record, when the source of that note is named. The Verification chapter records named observation against the criteria the decision named. The Human decision chapter records who accepted the consequence. The Action chapter records intent. The Learning chapter keeps the closed case: achieved, not_achieved, or inconclusive, with measured notes. None of those steps shows survival. None of them treats runway as survival. None of them measures runway for the customer. None of them measures survival for the customer. None of them attributes cash, risk, or capacity.
A duration at the current net burn is not survival
Cash Is Not Runway sits one step earlier. Cash is money received (collected) that can be spent now. Runway is how long operations can continue at the current net burn before cash is exhausted: cash divided by burn rate, with explicit assumptions. A cash balance can look healthy while runway is short if burn is high or collections are lumpy. Runway can look long while cash is trapped in receivables or restricted accounts. This essay starts after that split has been kept. Cash is not runway. The next refusal is that runway is not survival. A duration at the current net burn can be positive, and the business can still fail to meet payroll, vendors, debt service, or plant continuity through the next decision horizon. A short runway can still survive that horizon when the conditions this essay names are already true. Cash is not runway is a different refusal.
ARR Is Not Cash sits one step before that. ARR is the annualized value of recurring contracted subscription revenue that renews. Cash is money received (collected). The ARR is not cash. The cash is not runway. The runway is not survival. An annualized contract is not whether obligations will be met through the next decision horizon.
Revenue Is Not ARR sits one step before that. Recognized revenue is sales booked in a period. ARR is the annualized value of recurring contracted subscription revenue that renews. The revenue is not ARR. The ARR is not cash. The cash is not runway. The runway is not survival. A period booking is not whether the business can keep meeting obligations.
Impact Is Not Revenue sits one step before that. Business impact is attribution that a named decision changed cash, risk, or capacity. Impact is not revenue. The revenue is not ARR. The ARR is not cash. The cash is not runway. The runway is not survival. An attributed change is not survival through the next decision horizon.
Outcome Is Not Impact sits one step before that. A measured outcome is named observation against named criteria, stored as achieved, not_achieved, or inconclusive, with measured notes. The outcome is not the impact. The impact is not the revenue. The revenue is not ARR. The ARR is not cash. The cash is not runway. The runway is not survival.
Value Is Not Outcome keeps a reported outcome off the verified operational outcome the Decision Case was opened to change. A reported outcome, including a favorable KPI move, is not that value unless it is the verified change the case named and authorized. The value is not the outcome. The outcome is not the impact. The impact is not the revenue. The revenue is not ARR. The ARR is not cash. The cash is not runway. The runway is not survival.
Profit Is Not Value keeps the accounting result off the verified operational outcome. Profit is an accounting result under named cost rules. That figure is not the value, the value is not the impact, the impact is not recognized sales, recognized sales in a period are not ARR, ARR is not cash, cash is not runway, and runway is not survival. A profit figure beside a runway number still does not state whether obligations will be met.
Margin Is Not Profit keeps the unit remainder off bottom-line profit. Contribution margin is what remains after the cost to serve. That essay names profitable ARR as a later claim. This essay does not reach that claim. Cash is not margin. Cash is not runway. Runway is not survival. A positive unit remainder beside a runway figure still does not show survival.
Accountability Is Not Closure sits further back in the operating loop. Accountability is the continuing named ownership of results, exceptions, and learning after the plant move. Closure is the verified outcome recorded against that ownership: a measured result, not named intent. A named accountable human can own the result, and survival can still be unshown. A runway figure does not show it.
Runway has a different object than survival. Runway is how long operations can continue at the current net burn before cash is exhausted. Survival is whether the business can keep meeting obligations (payroll, vendors, debt service, plant continuity) through the next decision horizon. A sentence that only states a runway number does not say those obligations will be met. A sentence that only states survival does not say the duration was cash divided by burn rate, with explicit assumptions. The runway number can be long. Burn assumptions can still be wrong. Receivables can still never convert. A single customer concentration can still collapse. Critical capacity can still fail before cash does. The runway number can be short. Contracted inflows, a named cut date, or a financing path already closed can still carry the horizon.
Authorization Is Not Accountability sits further back. A named human decision that accepts consequence and routes intent to authorized execution systems answers who may start. That act is not accountability for the outcome after the work runs, not runway, and not survival. An authorized state can sit beside a runway figure while survival is still unshown. Recommend is not authorize. A recommendation that cites the runway figure does not accept the consequence, and it does not show survival.
Cash discipline earlier in the stack uses the same cash object and a different next refusal. Closure Is Not Cash keeps the operational close off the receipt. Closure is not cash. Cash collected is money received. Revenue recognized, in that essay, is the earning event recorded on the books. Cash Is Not Margin keeps the receipt off the unit remainder. Cash is not margin. Invoices paid means the customer settled the bill. Cash in the bank is money received. It is not contribution margin, and it is not profitable ARR. That refusal stops at the cost to serve. This essay does not repeat it. Cash that can be spent now is still not runway. Runway is still not survival. Margin is not profit. Profit is not value. A shutdown can collect cash, show a margin, print a profit, store a measured outcome, carry an impact claim, recognize a sale, hold an ARR figure, and state a runway — and the runway figure can still fail to state whether obligations will be met through the next decision horizon. None of those earlier records turns the duration into survival.
Action Is Not Execution keeps the write off the case. The Action chapter records intent. ACTION remains a locked disposition until authorized execution systems write the work order or isolate the equipment. A runway figure does not unlock that write. It does not show survival. It does not measure runway. It does not measure survival. It does not attribute cash, risk, or capacity to the decision. Sync does not write the work order. Sync does not clear equipment to run. Sync does not mark the case plant-execute. Sync does not book revenue. Sync does not recognize revenue. Sync does not measure ARR. Sync does not measure cash. Sync does not measure runway. Sync does not measure survival. Sync does not collect cash.
Runway answers how long operations can continue at the current net burn before cash is exhausted. It does not record whether the business can keep meeting obligations through the next decision horizon.
Survival is obligations through the next decision horizon
Survival is not a property of the runway figure. Survival is whether the business can keep meeting obligations (payroll, vendors, debt service, plant continuity) through the next decision horizon — not just whether a runway number is positive. The next decision horizon is the period the named decision has to cover: the time until the next decision that can change burn, inflows, financing, or capacity. The obligations have to be named. Payroll is pay owed to people. Vendors are amounts owed to suppliers. Debt service is amounts owed on debt. Plant continuity is whether the plant can keep operating through that horizon. A survival note that omits those obligations, or that omits the horizon, is a different claim from the survival this essay names.
This essay states no cash amount, no burn rate, no runway length, and no survival length. Stating a runway figure does not show the obligations. Stating that a runway number is positive does not show survival. The runway formula is cash divided by burn rate, with explicit assumptions. That formula does not state whether burn assumptions are wrong, whether receivables never convert, whether a single customer concentration collapses, or whether critical capacity (people, permits, plant) fails before cash does. It also does not state whether cash inflows are contracted, whether burn is cuttable on a named date, or whether a financing path is already closed.
Verification Is Not Optional states the gate for the check. The case stays open until named observation against named criteria is recorded as achieved, not_achieved, or inconclusive, with measured notes. That check is the measured result. It is not, by itself, runway, and it is not, by itself, survival. A recorded outcome without named obligations and a named horizon leaves survival unshown. A runway figure without those records leaves survival unshown. A positive runway number used as survival leaves the obligations unshown.
Learning Requires a Verified Outcome keeps what a later case is allowed to inherit. Learning inherits achieved, not_achieved, or inconclusive, with measured notes. It does not inherit a runway figure in place of that outcome, and it does not inherit survival in place of that outcome. A later shutdown that cites last time as if the runway figure were already survival is citing a duration as a claim about obligations. Sync must not auto-close, auto-authorize, or treat runway as survival as Learning credit.
Verified Is Not Assured keeps a verified stamp off standing confidence. A verified work package, inspection, or AI recommendation closes a claim about the past. Assurance is the standing claim that comes after. Runway, in this essay, is how long operations can continue at the current net burn before cash is exhausted. Survival is whether obligations can be met through the next decision horizon. Neither is a claim that the asset stays known-good, and neither is produced by storing achieved. A verified outcome can be not_achieved or inconclusive. Those results still close the claim about what was observed. They are not survival.
Correlation Is Not Causation is the same refusal one step earlier in the evidence. Two records that move together are not a cause. A survival note that moved in the same period as a runway figure is not, by that movement, proof that the duration is survival, and it is not proof that the obligations were met. The coincidence can inform a recommendation to investigate. It is not survival, and it is not proof the runway formula showed the horizon.
Runway is not survival. Runway is cash divided by burn rate, with explicit assumptions. Survival is whether the business can keep meeting obligations (payroll, vendors, debt service, plant continuity) through the next decision horizon — not just whether a runway number is positive.
A long runway can miss survival, and a short runway can still survive
The failure mode is ordinary after a runway figure is on the books. Runway is recorded, and the record is read as survival. A long runway can still miss survival if burn assumptions are wrong. The formula uses a burn rate. If that rate is not the current net burn, or if the rate is assumed constant when it is not, the duration is not the time operations can continue. The length of the stated runway does not repair a wrong assumption. Receivables never convert is a separate miss: amounts counted as future cash that are not received. A runway figure that depends on those receivables can look long and still miss survival when the cash does not arrive. A single customer concentration collapses is a separate miss: one customer accounts for enough of the inflows that losing that concentration removes the cash the duration assumed. Critical capacity (people, permits, plant) fails before cash does is a separate miss: the people, the permits, or the plant required to keep operating fail while cash remains. Cash still on hand does not meet plant continuity if the plant cannot run. It does not meet payroll if the people required to operate are gone. It does not meet the horizon if a permit required to operate has failed. Survival asks whether those obligations can be met. The runway number does not answer them.
The opposite case is just as ordinary. A short runway can still survive a decision horizon if cash inflows are contracted, burn is cuttable on a named date, or a financing path is already closed — none of which the runway formula itself proves. Cash inflows are contracted means the inflows that cover the horizon are already under contract, not merely assumed inside the burn rate. Burn is cuttable on a named date means a named date already exists on which burn will be reduced, and that date falls inside the horizon. A financing path is already closed means the financing that covers the horizon is already committed. The formula cash divided by burn rate does not record any of those three. A short positive number, or a short number that is still positive, is not proof they exist. A negative or exhausted reading is not proof they are absent. This essay states no savings figure, and it does not turn a long runway or a short runway into one.
Proxy Is Not Outcome already refuses to treat a KPI, a leading indicator, a model score, a green tile, or a closed work-order count as the verified operational outcome. A runway figure is a calculated duration, not that outcome, and not survival. A proxy is not the outcome. A measured outcome is not the impact. An impact claim is not recognized sales. A recognized sale is not ARR. ARR is not cash. Cash is not runway. Runway is not survival.
Green Is Not Go already refuses to treat a green tile as permission to run, clear, start, or leave equipment in service. A survival note painted beside that tile is not a stronger green. It is a display. Go still required a named human decision. The result after the plant move still requires a verified outcome. Runway still requires cash divided by the current net burn, with the assumptions named. Survival still requires named obligations through the next decision horizon. The color supplies none of them.
Complete Is Not Verified keeps a completion label off the check. A completed workflow is a completion label under the criteria someone chose. It is not named observation, not runway, and not survival. Cleared Is Not Complete keeps a clearance stamp off a finished claim. A cleared flag is not proof the work is finished, and it is not proof that a runway figure is survival.
Recommend Is Not Authorize keeps the proposal off the decision. A recommendation may say investigate because burn assumptions are wrong, because receivables never convert, because a single customer concentration collapses, because critical capacity fails before cash does, or because a short runway is being read as if contracted inflows, a named cut date, or a closed financing path were already proved. That proposal does not authorize the work, and it does not show survival. Recommend is not authorize.
Honesty Boundary Is Not Optional is the rule that keeps the words apart under the honesty and verification boundary. Sync states what was checked and what was not claimed. Calling runway survival crosses that boundary. Treating a long runway as survival while burn assumptions are wrong, receivables never convert, a single customer concentration collapses, or critical capacity fails before cash does is the same confusion. Treating a short runway as failure to survive, while cash inflows are contracted, burn is cuttable on a named date, or a financing path is already closed, is the same confusion. Sync refuses false precision. Sync refuses when evidence is insufficient. Sync does not measure runway. Sync does not measure runway for the customer. Sync does not measure survival. Sync does not measure survival for the customer. Sync does not measure cash. Sync does not measure cash for the customer. Sync does not collect cash. Sync does not book revenue. Sync does not recognize revenue. Sync does not measure ARR. Sync does not measure ARR for the customer.
Treating runway as survival records a duration as a claim that obligations will be met. A long runway can still miss survival if burn assumptions are wrong, receivables never convert, a single customer concentration collapses, or critical capacity (people, permits, plant) fails before cash does. A short runway can still survive a decision horizon if cash inflows are contracted, burn is cuttable on a named date, or a financing path is already closed — none of which the runway formula itself proves.
Surfacing a runway figure or a survival note is still a read
Sync may surface a runway figure or a survival note beside Evidence, Verification, and the closed outcome. Surfacing is still a read. The screen can show achieved, not_achieved, or inconclusive next to the criteria the case holds, next to a runway figure someone recorded elsewhere, and next to a note that obligations and a decision horizon were stated. Showing the figure does not write a CMMS work order. Showing the figure does not clear equipment to run. Showing the figure does not treat the case as plant execute. Showing the figure does not book revenue. Showing the figure does not recognize revenue. Showing the figure does not measure ARR. Showing the figure does not measure ARR for the customer. Showing the figure does not measure cash. Showing the figure does not measure cash for the customer. Showing the figure does not measure runway. Showing the figure does not measure runway for the customer. Showing the figure does not measure survival. Showing the figure does not measure survival for the customer. Showing the figure does not collect cash. Showing the figure does not attribute a change in cash, risk, or capacity. A read of a runway figure is still a read. A duration without named obligations and a named decision horizon leaves survival unshown.
Evidence from the plant beats the runway figure when the figure is being used as survival. If the evidence on the case does not support the named observation, the case refuses. If the evidence records a runway figure and does not record the obligations and the horizon, the case may store the figure as runway and must not store the figure as survival. If the evidence records wrong burn assumptions, receivables that never convert, a single customer concentration that collapses, or critical capacity that fails before cash does, the case may cite that record and must not store the runway figure as survival. If the evidence records contracted inflows, burn cuttable on a named date, or a financing path already closed, the case may cite that record and must not treat the runway formula as the proof of it. The label does not fill the gap, and it does not close it.
Stage-1 evidence is the record held on the case. A live connector that pulls historian or control-system tags sits outside this edition. A live connector tag pull is not a claim of this edition. Simulated or seeded telemetry and assets are practice records. A practice record that says runway is survival is not a customer plant release, and it is not a shown survival.
What the Decision Case may store
Evidence may cite a runway figure when the source of that figure is named, and when the citation says it is how long operations can continue at the current net burn before cash is exhausted — cash divided by burn rate, with explicit assumptions — rather than a measurement Sync performed, and rather than survival. Evidence may cite a survival note when the source is named and the obligations and the horizon are named: payroll, vendors, debt service, plant continuity, and the next decision horizon. Those citations are records of statements someone else made. They are not records that Sync measured runway for the customer. They are not records that Sync measured survival for the customer. They are not records that the runway figure is survival. A recommendation may say investigate because burn assumptions are wrong, because receivables never convert, because a single customer concentration collapses, because critical capacity fails before cash does, or because a short runway is being treated as if contracted inflows, a named cut date, or a closed financing path were already proved by the formula. The proposal does not show survival. Recommend is not authorize.
If the named person approves work, the case may store the intent. The intent is not execution, and named intent is not survival. A runway label does not perform the write and does not turn the duration into survival. Authorized execution systems write the work order or the isolation. Sync does not write the work order. Sync does not mark an asset closed. Sync does not write that state back. CMMS write-back is not a live product path. Billing write-back is not a live product path. Direct plant execute stays off.
Verification asks whether the authorized action did what the decision named. The check is named observation against named criteria, stored as achieved, not_achieved, or inconclusive, with measured notes. That record is the outcome the case is allowed to close when the criteria named an operational result. It does not, by itself, turn the outcome into runway, and it does not turn runway into survival. A named human decides. A named human remains accountable after the plant move. Survival stays unshown until the obligations and the next decision horizon are a separate record. Runway stays how long operations can continue at the current net burn before cash is exhausted even when someone calls the number survival. This essay does not supply either record as the other. Sync does not attribute a change in cash, risk, or capacity. Sync does not book revenue. Sync does not recognize revenue. Sync does not measure ARR. Sync does not measure cash. Sync does not measure runway. Sync does not measure survival. Sync does not collect cash.
Sync may surface a runway figure or a survival note beside Evidence, Verification, and the closed outcome. Surfacing is still a read. Sync refuses false precision. Sync refuses when evidence is insufficient. A named human decides. A named human remains accountable after the plant move. Runway stays how long operations can continue at the current net burn before cash is exhausted: cash divided by burn rate, with explicit assumptions. Survival stays whether the business can keep meeting obligations through the next decision horizon — not just whether a runway number is positive. A long runway that misses those obligations leaves survival unmet. A short runway that still meets them through contracted inflows, a named cut date, or a financing path already closed leaves the formula unproved as survival.
Learning keeps the closed case: achieved, not_achieved, or inconclusive, with measured notes. It does not keep runway as survival. A later question that cites a runway figure as if survival were already shown is citing a duration. A later question that cites a long runway while burn assumptions are wrong, receivables never convert, a single customer concentration collapses, or critical capacity fails before cash does is citing a figure that is not survival. A later question that cites a short runway as if survival had failed, while cash inflows are contracted, burn is cuttable on a named date, or a financing path is already closed, is citing a formula that did not prove the horizon. Sync must not auto-close, auto-authorize, or treat runway as survival as Learning credit.
Where the public statement lives
Field Manual v0 is the public contents of this loop. Start at the manuals index or open Sync Field Manual directly. Evidence may hold the runway figure, the survival note, or the measured result that was shown. Human decision may hold who accepted the consequence. Action may hold the intent that decision routed. Verification may hold the named observation. Learning may hold achieved, not_achieved, or inconclusive, with measured notes — the measured outcome, not survival. None of those steps is runway used as survival. The Honesty boundaries keep this edition from treating a runway figure as whether obligations will be met. Later editions can deepen a chapter. The spine stays in this order.
Decision Case spine
The standing rule sits beside the spine: Honesty boundaries.
What this article is not claiming
This is an essay about the Decision Case order, not a customer case study. It names no plant, states no savings figure, states no price, and claims no prevented failure. It states no OEM limit and no operating threshold. It states no cash amount, no burn rate, no runway length, and no survival length. It does not claim that runway is survival, writes a CMMS work order, clears equipment to run, books revenue, recognizes revenue, measures ARR, measures ARR for the customer, measures cash, measures cash for the customer, measures runway, measures runway for the customer, measures survival, measures survival for the customer, collects cash, or attributes a change in cash, risk, or capacity. It does not claim that Sync executes plant work. It does not claim CMMS write-back as a shipped product. It does not claim billing write-back as a shipped product. It does not invent a customer, a price, or a return. It does not treat a cash balance, contribution margin, invoices paid, or profitable ARR as the question. Cash is not runway is a different refusal.
Stage-1 readiness means a signed-in user can complete the Decision Case — question, evidence, recommendation, human decision, action, verification, and learning — and Field Manual v0 describes that journey. Walking those steps is not a claim that runway is survival. The verification step is where named observation against named criteria is stored as achieved, not_achieved, or inconclusive, with measured notes. This edition does not describe plant execute, a live connector tag pull, CMMS write-back, billing write-back, SMTP invite delivery, or automatic revocation of access on expiry as live. It does not describe Sync writing work orders, clearing equipment to run, marking a case plant-execute, starting equipment, releasing a hold, controlling the plant, booking revenue, recognizing revenue, measuring ARR, measuring cash, measuring runway, measuring survival, or collecting cash. Simulated or seeded telemetry and assets are practice records. They are not live plant results. Self-guided onboarding is not claimed as a live product path.
Human Decision Is Not Optional keeps a named person on the decision. The runway figure does not accept, reject, escalate, or return. The survival note does not either. A specific Sync decision, in this essay, is a named human decision recorded on a Sync case. Sync did not make it. A named human decides. A named human remains accountable after the plant move.

A Reliability Assessment asks whether the records can support a conclusion. A Strategic Pilot is a governed proof around one operating decision. The verification chapter records the measured result. The runway figure does not record the survival.
The series continues with Survival Is Not Solvency, on why survival is still not solvency. Survival is whether the business can keep meeting obligations (payroll, vendors, debt service, plant continuity) through the next decision horizon. Solvency is whether assets and claims structure can cover liabilities and pay debts as they come due over a structural horizon — balance-sheet and claim quality, not just near-term obligation continuity. A firm can survive a horizon and still be insolvent, or headed there. A solvent firm can still fail survival in a short horizon when liquidity timing fails or a concentration shock hits.
Read the case, then bring a question
Field Manual v0 states the order and the boundaries. Runway is how long operations can continue at the current net burn before cash is exhausted: cash divided by burn rate, with explicit assumptions. Survival is whether the business can keep meeting obligations (payroll, vendors, debt service, plant continuity) through the next decision horizon — not just whether a runway number is positive. A long runway can still miss survival. A short runway can still survive a decision horizon. The runway formula itself proves neither. The Reliability Engineer workspace is where a signed-in Decision Case is completed. A Reliability Assessment is the bounded review when the question is whether the records can support a conclusion. None of those is a claim that Sync executes plant work, books revenue, recognizes revenue, measures ARR, measures ARR for the customer, measures cash, measures cash for the customer, measures runway, measures runway for the customer, measures survival, measures survival for the customer, collects cash, attributes cash, risk, or capacity, declares a return, that CMMS write-back is live, that billing write-back is live, or that self-guided onboarding is a live product path.
