Core Idea

Bloom-and-bust cycle names the structural pattern in which a system undergoes rapid, resource-saturating growth followed by a sharp collapse, where the collapse itself generates secondary stress from the decomposition or aftermath of the boomed population. Its distinctive structural commitments are four: a transient permissive condition allows growth to outrun normal limits; growth is positive-feedback dominated until a limit binds — resource exhaustion, toxin accumulation, or external removal; collapse is rapid relative to the bloom's duration; and the collapse produces an aftermath load in which the dead or departed elements impose their own cost on the substrate that supported the bloom, often surpassing the cost the bloom itself imposed.

The fourth commitment is what distinguishes the pattern from simpler boom-bust or overshoot-collapse shapes: the aftermath is itself an active stressor, not merely a return to baseline. Where overshoot says "you ran out of resource," bloom-and-bust adds "and the carcasses pile up and become a second crisis." Where economic boom-bust names the cyclic profile, bloom-and-bust adds the structural prediction that the worst damage may arrive after the visible peak, when the decomposition or unwinding produces its own load on the same substrate that supported the growth. The prime thus directs attention past the dramatic, visible collapse to the delayed, diffuse cost that follows it.

How would you explain it like I'm…

Boom Then Rotten Mess

Imagine algae spreading super fast all over a pond until it's bright green everywhere. Then it runs out of food and dies almost all at once. But the trouble isn't over — all those dead bits rot and stink and make the water worse, sometimes worse than when the pond was just crowded. The biggest mess comes after the big green peak, not during it.

Crash Plus Cleanup Crisis

A bloom-and-bust cycle is when something grows explosively fast, gobbling up resources, then crashes hard. But there's a twist: after the crash, all the dead or leftover stuff becomes its own new problem. Four things define it — a temporary lucky condition lets growth shoot past the normal limits; growth feeds on itself until something finally runs out (food, space) or poison builds up; the collapse is fast compared to how long the boom lasted; and the aftermath, the rotting carcasses or leftovers, dumps its own cost on the very place that fed the boom. That last part is the surprise: the worst damage can land after the peak, not during it.

The Costly Aftermath

A Bloom-and-Bust Cycle is rapid, resource-saturating growth followed by a sharp collapse, where the collapse itself generates a second wave of stress from the decomposition or aftermath of the boomed population. Four commitments define it: a transient permissive condition lets growth outrun its normal limits; growth is positive-feedback dominated until a limit binds — resource exhaustion, toxin accumulation, or external removal; collapse is rapid relative to the bloom's duration; and the collapse produces an aftermath load, in which the dead or departed elements impose their own cost on the substrate that supported the bloom, often surpassing the bloom's own cost. That fourth commitment is what separates it from a plain boom-bust or overshoot-collapse: the aftermath is an active stressor, not just a return to baseline. Overshoot says 'you ran out of resource'; bloom-and-bust adds 'and the carcasses pile up and become a second crisis,' directing attention to the delayed, diffuse damage after the visible peak.

 

A Bloom-and-Bust Cycle names the structural pattern in which a system undergoes rapid, resource-saturating growth followed by a sharp collapse, where the collapse itself generates secondary stress from the decomposition or aftermath of the boomed population. Its distinctive structural commitments are four: a transient permissive condition allows growth to outrun normal limits; growth is positive-feedback dominated until a limit binds — resource exhaustion, toxin accumulation, or external removal; collapse is rapid relative to the bloom's duration; and the collapse produces an aftermath load in which the dead or departed elements impose their own cost on the substrate that supported the bloom, often surpassing the cost the bloom itself imposed. The fourth commitment is what distinguishes the pattern from simpler boom-bust or overshoot-collapse shapes: the aftermath is itself an active stressor, not merely a return to baseline. Where overshoot says 'you ran out of resource,' bloom-and-bust adds 'and the carcasses pile up and become a second crisis.' Where economic boom-bust names the cyclic profile, bloom-and-bust adds the structural prediction that the worst damage may arrive after the visible peak, when the decomposition or unwinding produces its own load on the same substrate that supported the growth. The prime thus directs attention past the dramatic, visible collapse to the delayed, diffuse cost that follows it.

Structural Signature

the transient permissive condition (pulse) — the positive-feedback-dominated bloom — the binding limit that halts growth — the rapid collapse relative to the bloom — the aftermath load imposed by the collapsed material on the substrate — the peak-scaled magnitude of that load — the recoverable-versus-substrate-damaging fork

A configuration exhibits the bloom-and-bust pattern when each of the following holds:

  • A permissive pulse. A transient condition relaxes the normal limit on growth, allowing a population or activity to expand beyond its usual bound.
  • A positive-feedback bloom. Growth is reinforcing-loop-dominated, running rapidly and resource-saturatingly until a limit binds.
  • A binding limit. Some constraint — resource exhaustion, toxin accumulation, external removal — halts the growth.
  • A rapid collapse. The decline is sharp relative to the bloom's duration: a bust, not a gentle decay.
  • An aftermath load. Critically, the collapsed material itself becomes an active stressor — the dead or departed elements impose a new cost on the same substrate that supported the bloom (decomposition, denuded ground, abandoned infrastructure, released contents). This fourth element distinguishes the pattern from simple overshoot-collapse, where the bust is merely a return to baseline.
  • Peak-scaled aftermath. The aftermath load scales with the peak of the bloom, not its average, so it can exceed the bloom's direct cost and arrives after the visible peak.
  • A recoverable/damaging fork. The bust either returns the substrate cleanly to baseline or damages it enough to prevent the next bloom or shift it to a new regime — a distinction that determines whether the aftermath is a transient or a permanent state change.

Composed, these direct attention past the dramatic visible collapse to the delayed, diffuse, often larger cost the collapse generates — recasting the management question from "prevent the bloom" to "manage the aftermath, sized to the peak."

What It Is Not

  • Not a cascade. A cascade propagates failure outward through a network link by link; bloom-and-bust is a temporal arc in one population — grow, collapse, leave an aftermath load — without the node-to-node transmission a cascade requires.
  • Not a simple oscillation or cycle. A clean cycle returns to baseline each period; bloom-and-bust's distinguishing fourth phase is that the collapse generates an active aftermath stressor, so the bust is not a mere return.
  • Not overfitting of capacity / plain overshoot-collapse. Overshoot says "you ran out of resource and fell back"; bloom-and-bust adds that the dead or departed material imposes a new cost on the same substrate, often exceeding the bloom's direct cost.
  • Not a tipping_points_or_phase_transitions event alone. A phase transition crosses a threshold into a new regime; bloom-and-bust may end in such a regime shift (the substrate-damaging fork) but is centrally the four-phase pulse-bloom-bust-aftermath trajectory.
  • Not critical_mass. Critical mass is the threshold at which a self-sustaining process ignites; it describes only the onset of the bloom, not the collapse or the peak-scaled aftermath the prime centres on.
  • Not bottleneck. A bottleneck is a persistent rate-limiting constraint; bloom-and-bust is a transient permissive pulse that relaxes the normal limit, then a collapse when a limit re-binds.
  • Common misclassification. Treating a system that returns cleanly to baseline as bloom-and-bust and over-provisioning aftermath response. The test is whether the collapsed material does anything to the substrate; if it merely vacates, a simpler cycle or overshoot prime governs.

Broad Use

Marine eutrophication supplies the canonical case — a nutrient pulse fuels an algal bloom, the bloom exhausts its niche and collapses, and bacterial decomposition of the dead biomass depletes the water column's oxygen, killing fish and benthic life over an area larger than the original bloom. The pattern recurs:

  • Locust outbreaks: favourable rains allow a swarm that consumes vegetation and then collapses, with the post-collapse denuded landscape and secondary starvation exceeding the swarm's direct damage.
  • Resource towns: a discovery pulls workers and capital to a remote site that swells and then empties on exhaustion, with abandoned infrastructure and remediation costs outlasting and often exceeding the boom-era gains.
  • Viral content cycles: content blooms across a network, saturates the attention niche, and busts, with the aftermath — overcommitted creators, peak-valuation contracts, orphaned communities — producing secondary stress.
  • Startup hype cycles: capital floods a sector that reaches a valuation peak and collapses, with stranded talent, peak-spec infrastructure, and debt-laden codebases imposing ongoing drag.
  • Tumour proliferation: a resistant clonal population expands, collapses under treatment, and produces tumour lysis — released intracellular contents overwhelming the organism's clearance systems — as a distinct crisis.
  • Imperial overstretch and fermentation: rapid expansion then contraction leaving disrupted zones and displaced populations; a sugar pulse driving yeast growth whose alcohol byproducts collapse the population and sterilise the substrate.

In each, the load-bearing move is to identify the pulse, the saturation limit, the collapse, and the aftermath load generated by the collapse itself.

Clarity

The prime sharpens a confusion that pervades naive boom-bust analyses: that the bust is the worst of it. In many systems the bust is visible, dramatic, and clearly bad — but the aftermath load it generates is delayed, diffuse, and often the larger cost. Reaching for bloom-and-bust forces the analyst to look past the visible collapse and ask: what does the collapse leave behind, and what does the substrate have to do with it?

The prime also distinguishes systems that return cleanly to baseline after collapse — where the right description might be a simple cycle or oscillation — from systems where the path home is itself a crisis. This is a real fork, because the two cases imply different management. A clean-returning system can be left to recover; an aftermath-loaded one requires active management of the post-collapse phase, and mistaking the second for the first leaves the larger, delayed cost unaddressed precisely because attention was spent on the dramatic but lesser peak.

Manages Complexity

The pattern compresses a complex multi-stage trajectory into a diagnostic four-phase template — pulse, bloom, bust, aftermath — and predicts that the fourth phase is where intervention design should focus when the bust is unavoidable. This recasts the policy question from "can we prevent the bloom?" to "can we manage the aftermath?" — which is often far more tractable, because the bloom may be driven by forces outside control while the aftermath is a known, bounded load that can be reserved against.

The compression also calibrates the size of the response. Because the aftermath load scales with the peak of the bloom rather than its average, the template tells the analyst that a cleanup fund, a wind-down plan, or a remediation reserve should be sized to the peak, not the typical case. This is a non-obvious sizing rule that falls directly out of the structure, and it prevents the common under-provisioning that occurs when the post-collapse reserve is calibrated to average conditions and is then overwhelmed by the aftermath of an unusually large bloom.

Abstract Reasoning

Bloom-and-bust composes with several primes. With overshoot and collapse: overshoot describes the bloom-to-bust transition, and bloom-and-bust extends the analysis through the aftermath. With nucleation and threshold: the pulse-to-bloom transition is often threshold-mediated — below threshold no bloom, above it runaway. With critical mass and self-perpetuation: positive feedback maintains the bloom, and the collapse marks the moment self-perpetuation fails as resource exhausts or toxin accumulates. And with delayed cost and externality: the aftermath load is a delayed cost generated by the bloom, often borne by parties who did not benefit from it — an externality shape.

Reasoning about a system suspected of being bloom-and-bust prone asks a four-part question: what permits the bloom; what bounds it; how rapid is the collapse relative to the bloom; and what does the collapsed material do to the substrate? The fourth part is the diagnostic that separates this prime from its neighbours, and it forks into a consequential distinction: some busts return cleanly while others damage the substrate enough that the next bloom cannot occur, or the substrate transitions to a different regime. Surfacing this fork — recoverable versus substrate-damaging bust — is the abstract payoff, because it determines whether the aftermath is a transient to be weathered or a permanent state change to be prevented.

Knowledge Transfer

The roles map across substrates: the permissive pulse is the nutrient runoff, the favourable rain, the resource discovery, the capital inflow, the sugar charge; the positive-feedback bloom is the algal growth, the swarm, the town's swelling, the sector's expansion; the rapid collapse is the die-off, the price crash, the valuation collapse; and the aftermath load is the oxygen-depleting decomposition, the denuded landscape, the abandoned infrastructure, the stranded talent, the tumour lysis. Stripped of ecological vocabulary, the prime is "saturating growth, sharp collapse, and a collapse-generated load on the same substrate that often exceeds the bloom's direct cost."

The intervention pattern is portable as a small set of moves. Do not focus exclusively on bloom suppression: algal-bloom management oxygenates the water during and after collapse, resource-town policy provides closure funds, and tumour-lysis is anticipated with hydration and clearance support — in each, the aftermath is managed, not only the bloom prevented. Anticipate the aftermath shape, which often differs from the bloom's substance — dead algae become an oxygen problem, failed startups a hiring-market problem, abandoned mines a water-table problem — so the analyst asks "what does this bloom become when it dies?" Size the reserve to the peak, not the average. And distinguish recoverable from substrate-damaging busts. A worked instance shows the substance: a coastal estuary receiving a nitrogen pulse blooms twentyfold in ten days, collapses in three to five, and then over the following two weeks the bacterial decomposition produces a hypoxic dead zone of hundreds of square kilometres whose losses exceed the bloom's direct losses by an order of magnitude and whose recovery takes years. The structurally identical analysis applies to a 1980s oil-town boom whose price collapse triggered out-migration, leaving empty subdivisions and a public-finance hangover that defined municipal budgets for fifteen years — the aftermath, not the peak, defining the cost.

Examples

Formal/abstract

Coastal eutrophication is the prime's canonical case, and its four phases can be traced as a worked dynamical instance. The permissive pulse is a nitrogen runoff event that relaxes the nutrient limit normally bounding phytoplankton. The positive-feedback bloom follows: with nutrients unbounded, algal biomass grows near-exponentially, roughly twentyfold in ten days, until a binding limit — nutrient exhaustion or self-shading — halts it. The rapid collapse takes three to five days, far shorter than the bloom's growth phase, a true bust. The phase that distinguishes this prime from simple overshoot is the aftermath load: the dead algal biomass sinks and bacterial decomposition consumes dissolved oxygen, producing a hypoxic dead zone of hundreds of square kilometres that kills fish and benthic life over an area larger than the bloom and persisting for weeks after the visible peak. The prime's peak-scaled prediction is exact — the oxygen debt scales with the biomass peak, not the average, so the dead zone after an unusually large bloom is disproportionately severe. And the recoverable-versus-damaging fork applies: a mild event clears, but a severe one can shift the benthos to a persistent low-oxygen regime. The intervention follows directly — manage the aftermath (oxygenate the water column during and after collapse) rather than only attempting to prevent the bloom, and size the remediation reserve to the peak.

Mapped back: The nitrogen pulse is the permissive condition, exponential algal growth is the positive-feedback bloom, nutrient exhaustion is the binding limit, the die-off is the rapid collapse, and the oxygen-depleting dead zone is the peak-scaled aftermath load that exceeds the bloom's direct cost.

Applied/industry

A resource boomtown runs the prime in a regional-economics substrate, and the fourth phase is where the real cost lives. The permissive pulse is a mineral or oil discovery that relaxes the normal economic constraints on a remote site. The positive-feedback bloom is migration and capital inflow reinforcing each other — workers draw services, services draw more workers — swelling the town far beyond its baseline. The binding limit is resource exhaustion or a price crash, which halts the growth, and the rapid collapse is sharp out-migration once the jobs vanish. The distinguishing aftermath load is what the collapse leaves on the same substrate: abandoned subdivisions, stranded infrastructure, environmental remediation liabilities, and a public-finance hangover — costs that, in the 1980s oil-town busts, defined municipal budgets for fifteen years and exceeded the boom-era gains. The prime's diagnostic recasts policy from "prevent the boom" (often impossible, since the price is exogenous) to "manage the aftermath" — provide closure funds and wind-down plans, sized to the peak population rather than the average, because the remediation load scales with the peak. A structurally identical applied instance is a startup hype cycle, where capital floods a sector, valuations peak and crash, and the aftermath — stranded talent, peak-spec infrastructure, debt-laden codebases — imposes ongoing drag on the labour and capital markets.

Mapped back: The discovery is the pulse, the self-reinforcing in-migration is the bloom, exhaustion or price-crash is the binding limit, out-migration is the collapse, and abandoned infrastructure plus the fiscal hangover is the peak-scaled aftermath load borne by the same substrate.

Structural Tensions

T1 — Aftermath Load versus Clean Return (boundary with a competing prime). The prime's distinguishing fourth commitment is that the collapse generates an active aftermath load — without it, the situation is simple overshoot-collapse or a cycle, where a competing prime applies. The boundary is genuinely hard to place in advance: whether the bust leaves an active stressor or merely returns to baseline is often unknown until after. Failure mode: applying bloom-and-bust's aftermath-management apparatus to a system that returns cleanly, over-provisioning for a crisis that never comes — or worse, missing that a nominal cycle has crossed into substrate damage. Diagnostic: ask whether the collapsed material does anything to the substrate, or merely vacates it; no active aftermath means the simpler prime governs.

T2 — Bloom Prevention versus Aftermath Management (scopal/lever). The prime recasts the policy question from "prevent the bloom" to "manage the aftermath," because the bloom is often driven by exogenous forces while the aftermath is bounded and reservable. But this reframe can over-rotate: some blooms are preventable at the pulse, and surrendering bloom prevention to focus on aftermath forgoes the cheaper upstream fix. Failure mode: building elaborate post-collapse remediation for a bloom whose permissive pulse could simply have been throttled (capping the nutrient runoff, the capital inflow). Diagnostic: ask whether the permissive pulse is genuinely exogenous and uncontrollable; if it is controllable, prevention may dominate aftermath management on cost.

T3 — Peak-Scaled Reserve versus Average Provisioning (scalar/sizing). The prime delivers a sharp sizing rule: the aftermath load scales with the peak, not the average, so reserves must be sized to peak. But peak-sizing is expensive and the peak is a tail event; sizing every reserve to the worst conceivable bloom can be ruinously conservative. The rule that prevents under-provisioning invites over-provisioning. Failure mode: holding a remediation reserve sized to a once-in-a-century bloom against routine cycles, sinking capital that the average case never needs. Diagnostic: weigh the cost of carrying a peak-sized reserve against the distribution of bloom peaks; the rule sets a floor for catastrophe, not a target for every season.

T4 — Visible Peak versus Delayed Cost (temporal/attention). The prime's whole value is redirecting attention from the dramatic visible collapse to the delayed, diffuse aftermath. But attention and resources are finite, and the visible peak often demands genuine response too — the redirection can swing too far, neglecting the immediate crisis to prepare for the delayed one. Failure mode: so fixated on the coming aftermath (the dead zone, the hangover) that the acute collapse phase (the fish kill, the layoffs) is under-resourced as it happens. Diagnostic: confirm the visible collapse is itself adequately handled before reallocating to aftermath; the prime corrects under-attention to the aftermath, not attention to the peak.

T5 — Recoverable versus Substrate-Damaging Bust (modal/irreversibility). The prime forks the aftermath into a transient to be weathered versus a permanent regime shift to be prevented — but which fork obtains is often undecidable until the substrate has either recovered or not. Acting on the wrong fork is costly in both directions. Failure mode: treating a substrate-damaging bust as recoverable (letting it ride, expecting baseline return) when the substrate has tipped to a new regime that no longer supports the next bloom — or pouring prevention into a bust that would have cleared on its own. Diagnostic: look for evidence that the bust degrades the substrate's capacity to support future blooms; reversible busts leave that capacity intact.

T6 — Bloom Substance versus Aftermath Substance (qualitative transform). The prime warns that the aftermath often differs in kind from the bloom — dead algae become an oxygen problem, failed startups a labour-market problem — so the aftermath must be anticipated by transformation, not extrapolation. This is a real reasoning hazard: the analyst who plans for "more of the bloom's problem" prepares for the wrong crisis. Failure mode: provisioning aftermath response in the bloom's own terms (more algae-removal capacity) when the actual load is a transformed quantity (oxygen depletion) that the bloom-shaped response cannot address. Diagnostic: ask "what does this bloom become when it dies?" — if the answer is a different substance on a different subsystem, the response must be designed for the transform, not the original.

Structural–Framed Character

Bloom-and-bust sits firmly on the structural end of the structural–framed spectrum, and its low aggregate reflects a pattern that is essentially a bare dynamical shape — saturating growth, sharp collapse, and a collapse-generated load on the same substrate — with only the faintest residue of its ecological birthplace. Three of the five diagnostics read cleanly structural with no hesitation. Evaluative weight is nil: the four-phase pulse-bloom-bust-aftermath trajectory carries no inherent approval or disapproval. An algal bloom is a nuisance, a tumour's clonal expansion is lethal, a startup boom is celebrated until it isn't — the prime is value-neutral until a substrate specifies what is growing and who bears the aftermath load. Institutional origin is likewise absent: nothing about the pattern depends on human conventions, contracts, or formal rules; the binding limit and the peak-scaled aftermath are properties of a feedback system meeting a constraint. And human-practice-bound scores zero because the pattern runs indifferently across physical, biological, and economic substrates — phytoplankton in a water column, yeast sterilising its own medium with alcohol, a locust swarm denuding vegetation. These run with no human practice present at all; the resource-town and startup cases are merely two more substrates among many, not the home of the pattern.

The two mild half-points — vocabulary travels (0.5) and import versus recognize (0.5) — are what keep the aggregate from bottoming out entirely, and both trace to the same source: the prime's ecological origin in marine eutrophication. "Bloom," "bust," and "aftermath load" carry a faint smell of algae and dead biomass, so a thin layer of translation is needed before the shape reads natively in a capital-markets or oncology substrate — the swarm must be re-described as migration, the decomposition as a hiring-market overhang. But this is mild translation, not a heavy home vocabulary that must travel intact: each domain can and does tell the pattern in its own words (out-migration, tumour lysis, debt-laden codebases), which is exactly why the import-versus- recognize criterion also sits at a half rather than a full point. Invoking bloom-and-bust on a new system does not import an interpretive frame so much as recognise a dynamical structure already wired into it; the only "import" is the nudge to look past the visible collapse to the delayed, peak-scaled load — an attentional reframe, not a normative or institutional one. With evaluative weight, institutional origin, and practice-boundedness all at zero and only a residual ecological-vocabulary tax on the remaining two, every diagnostic that matters points the same way: this is a structural prime that recognises a pattern, lightly dressed in the language of the tide pool where it was first named.

Substrate Independence

Bloom-and-bust is a strongly substrate-independent prime — composite 4 / 5 on the substrate-independence scale. Its domain breadth is wide (4 / 5): the bloom-collapse-with-aftermath-load shape recurs across ecology (algal blooms and the dead-zone load they leave), locust outbreaks, resource boomtowns (the bust leaving stranded infrastructure), viral content (a spike followed by a depleted attention commons), startups (hypergrowth then collapse with obligation overhang), and tumours. Its structural abstraction is high (4 / 5): the distinctive commitment — that the collapse leaves a persistent aftermath load, not a clean return to baseline — is stated in medium-neutral terms, carries no evaluative weight or institutional origin, and is recognised as a pattern already operating in a system rather than projected onto it; the dynamic runs in purely physical and biological substrates. What holds it to a 4 is a residual ecological-vocabulary tax (transfer evidence 4 / 5): the aftermath-load shape ports cleanly and is documented across these domains, but the bloom/bust lexicon is borrowed from the tide pool where it was named.

Not to Be Confused With

The nearest neighbour is cascade, and the two are easy to merge because both describe a system going badly wrong in a way that spreads. But they differ in the direction and topology of the spread. A cascade propagates through connectivity: one failed node tips its neighbours, which tip theirs, so the damage travels link by link across a network in space. Bloom-and-bust propagates through time within a single population: a permissive pulse drives saturating growth, a limit binds, the population collapses, and the collapsed material imposes an aftermath load on the same substrate. There is no node-to-node transmission — the harm is generated by the population's own boom-and-collapse arc, not relayed across a graph. The two can compose (a bloom's aftermath might trigger a downstream cascade), but the prime's distinctive content — the peak-scaled aftermath that arrives after the visible collapse — is a temporal prediction about one population, not a spatial one about a network. A reasoner who reads bloom-and-bust as a cascade will look for the spreading link and miss the delayed, in-place aftermath that is the real cost.

A second confusion is with plain overshoot-collapse and, more broadly, oscillation. An oscillating or simply overshooting system rises past a limit and falls back, and in the clean case it returns to baseline ready for the next cycle. Bloom-and-bust's defining fourth commitment is precisely what these lack: the collapse produces an active stressor — decomposing biomass that depletes oxygen, abandoned infrastructure, tumour lysis — that loads the same substrate and can exceed the bloom's direct cost. The discriminating question is whether the bust is merely a return or itself a crisis. This is a genuinely hard boundary to draw in advance (the prime's own T1 tension), but it is the load-bearing distinction: a clean-returning system can be left to recover, whereas an aftermath-loaded one demands active management of the post-collapse phase, sized to the peak. Treating a bloom-and-bust as a simple oscillation leaves the larger, delayed cost entirely unaddressed.

Finally, bloom-and-bust is distinct from critical_mass, which a reader might invoke because both involve a self-reinforcing process igniting. Critical mass names the threshold of onset — the point at which positive feedback becomes self-sustaining — and says nothing about what follows. Bloom-and-bust includes a critical-mass-like ignition as its pulse-to-bloom transition but extends through the binding limit, the rapid collapse, and the peak-scaled aftermath that is its whole reason for being. Reasoning with critical mass alone captures only why the bloom starts; it misses the collapse and the aftermath load, which is exactly where the prime directs management attention.
