leo: rewrite priority inheritance with three-thread synthesis

- CS origin: scheduler detects dependency, reprices in real time (solved problem)
- Hidalgo mechanism: value flows through overlapping competency networks in product space, not linear dependency chains
- Investment application: markets lack the scheduler — recognizing product-space adjacency before the market IS the priority inheritance protocol

Grounded in m3ta's review: jet engines → rockets is shared competencies (Hidalgo), not prerequisite components. The CS thread-priority analogy provides structural clarity. The gap between automated correction (CS) and market mispricing (investment) IS the thesis.

 # Priority inheritance means nascent technologies inherit economic value from the future systems they will enable because dependency chains transmit importance backward through time
 
-In computer science, priority inheritance prevents low-priority tasks holding resources needed by high-priority tasks from blocking progress — the low-priority task temporarily inherits the high priority. Applied to investment: nascent technologies that are prerequisites for high-value future systems inherit the priority (and eventually the valuation) of those future systems.
+Value flows backward from destinations to prerequisites. This is structurally identical across three domains — computer science, economic development, and investment — but the critical difference is whether the system has a mechanism to detect and correct for it.
 
-The copper example makes this concrete: copper was economically marginal in medieval Europe — useful for pots and decoration but not a strategic resource. Faraday's discovery of electromagnetism retroactively made copper essential infrastructure for the entire electrical age. The resource's value was determined by a future knowledge state that didn't exist when the resource was acquired. An investor who understood the dependency chain — electrification requires conductive materials, copper is the best conductor — could have captured the value inheritance before the market priced it in.
+## The CS origin
 
-The investment implication: identifying which current technologies are prerequisites for which future systems allows you to invest in the inheritance chain before the market prices in the future system. This is not prediction — it's dependency analysis. You don't need to know WHEN the future system arrives, only that it REQUIRES certain prerequisites, and those prerequisites aren't yet valued at their inherited importance.
+In real-time operating systems, priority inheritance prevents priority inversion — the pathology where a low-priority task holding a resource needed by a high-priority task blocks system progress. The protocol: the low-priority task temporarily inherits the priority of the highest-priority task waiting on its resource, ensuring it completes and releases the resource promptly. The scheduler DETECTS the dependency and reprices priority in real time. No mispricing persists. This is a solved problem — it's built into the scheduler because failing to handle it causes the whole system to stall.
 
-This provides a mechanistic basis for "investing in the future" that goes beyond conviction or narrative. It's following dependency chains, not making bets. The mechanism is falsifiable: if the future system doesn't materialize, the inheritance doesn't happen. If it does, the prerequisite technologies inherit its valuation.
+## The Hidalgo mechanism
+
+Products are crystals of imagination — they physically embody specific pools of knowledge and knowhow (Hidalgo 2015). Above the personbyte limit, this knowledge must be chunked across networks of specialists. These networks are geographically sticky and learn experientially. Economies diversify toward related varieties because the knowledge networks that can build one product can build nearby products in capability-space.
+
+Rockets are more complicated than jet engines but they sit nearby in product space. The metallurgy, combustion science, thermodynamics, precision manufacturing, and systems integration competencies overlap massively. Having a domestic jet engine industry means you already have the human networks, the tacit knowledge, the supplier base, the institutional capacity. The jet engine industry is a stepping stone — not because jet engines are a prerequisite component OF rockets, but because the PEOPLE and KNOWLEDGE that build jet engines are close in capability-space to the people and knowledge needed for rockets. The intermediate industry trains the pool of experts and develops the networks that will eventually be capable of building rocket engines.
+
+The framework generalizes: lithium inherited value from battery technology via shared electrochemistry expertise. GPU architectures inherited value from deep learning via shared parallel-compute knowledge. Orbital launch capacity inherits value from satellite constellations via shared propulsion and guidance systems. In each case, the value transmission happens through overlapping competency networks, not linear dependency chains.
+
+## The investment application
+
+Markets price current utility. The jet engine company gets valued on jet engine revenue. The adjacency value — that this knowledge network is a stepping stone to rockets, space, and everything nearby in product space — is systematically underpriced. The repricing only happens AFTER the destination industry materializes, by which point the stepping stone has already been acquired or replicated.
+
+The investment thesis IS the scheduler. Recognizing product-space adjacency before the market does is literally performing the function that CS schedulers perform automatically. You're manually running the priority inheritance protocol that markets lack. Computer systems correct for backward value flow in real time. Markets systematically don't. That gap is the investment opportunity.
+
+The copper case makes this concrete: copper was economically marginal in medieval Europe. Faraday's discovery of electromagnetism retroactively made copper essential infrastructure for the entire electrical age. The resource's value was determined by a future knowledge state that didn't exist when the resource was first valued. An investor who understood product-space adjacency — electrical systems require conductors, copper has the best conductivity-to-cost ratio at scale — could have identified the inheritance relationship before the market priced it in.
+
+## Challenges
+
+The framework is more descriptive than predictive. Identifying dependency chains in retrospect is easy; identifying them prospectively requires predicting which future industries will materialize AND which current industries sit adjacent in product space. Many apparent stepping stones fail — hydrogen fuel cells were expected to inherit priority from clean transportation, but EVs captured that path instead. The "temporal gap between visibility and pricing" may also be vanishingly short in efficient markets.

 Relevant Notes:
-- [[value is doubly unstable because both market prices and underlying relevance shift with the knowledge landscape]] — priority inheritance works because value is doubly unstable
-- [[products are crystallized imagination that augment human capacity]] — prerequisite technologies embody the knowledge needed to reach the future system
-- [[the personbyte is a fundamental quantization limit on knowledge accumulation]] — complex future systems require knowledge networks that prerequisite technologies enable
+- [[value is doubly unstable because both market prices and underlying relevance shift with the knowledge landscape]] — priority inheritance works because value is determined by knowledge states, and knowledge states change
+- [[products are crystallized imagination that augment human capacity]] — the stepping stone mechanism requires products to embody transferable knowledge
+- [[the personbyte is a fundamental quantization limit on knowledge accumulation]] — complex future systems require knowledge networks that prerequisite industries cultivate
+- [[market volatility follows power laws from self-organized criticality not the normal distributions assumed by efficient market theory]] — if markets are at criticality rather than efficient, stepping-stone adjacency is systematically mispriced
