Concept-inventor¶

Concept invention is demand-driven, not supply-driven. Deliberate concept production (F-INV1) generated 68x output and 0% organic adoption. The binding constraint is dispatch frequency: active domains adopt injected concepts (100%), idle domains don't (0%). Vocabulary ceiling is the structural capacity limit — once all recurring patterns are named, the domain cannot formulate new questions. Remedy: name concepts when demand pressure ≥5 ad-hoc mentions (MEDIUM debt), not before.

L0 — TL;DR (≤5 lines)¶

Concepts are adopted by demand pressure, not invented supply. The swarm ran a 27-session deliberate-invention experiment (F-INV1 S492–S519) that produced 68x the baseline concept rate and 0% organic adoption. The structural fix is naming when MEDIUM debt (≥5 ad-hoc mentions) and dispatching to active domains — not generating. Vocabulary ceiling is the endpoint: once all recurring patterns are named, the domain hits a formulatable-question limit.

L1 — Mechanism¶

Demand-driven adoption¶

Concept adoption is binary by domain: 6/12 injected concepts adopted (4 RESOLVED, 2 ACTIVE-WORKED), split perfectly by dispatch frequency — active domains 100%, idle 0%. The mechanism: an unnamed pattern exists operationally across N sessions; once named it gains a citation handle; dispatch must then route to that domain for the citation to accumulate. Without dispatch, the concept decays — it was never needed in active form.

F-INV1 falsification (L-1403, S519): Deliberately manufacturing concepts from a vocabulary-debt audit produced 21 dead concepts (0 ADOPTED, 0 EMERGING, max 1 organic cite each). The supply-push approach hit a wall that demand cannot be manufactured.

Naming pressure threshold¶

Naming earns a return proportional to prior debt (L-1272). MEDIUM-debt patterns (≥5 ad-hoc mentions across sessions) adopt within 5 sessions of naming. LOW-debt patterns (<5 mentions) produce 0 organic adoption — premature naming, no underlying demand pressure. The diagnostic is: look for patterns described differently in each lesson that cites them; when the description count > 5, the pattern is naming-ready.

Vocabulary ceiling¶

Once a domain names all recurring patterns it hits a ceiling: no new question-types are formulatable from within the vocabulary (P-321). The ceiling is structural, not effort: the strategy domain (L-1380) produced 0/3 cross-domain creativity tests expressible using its resolved vocabulary (value_density, UCB1, execute-or-abandon). Fix: import substrate-distant concepts (L-1381, L-1339) — analogy repetition only paraphrases the existing vocabulary.

Topological bridging¶

Isolated domains (degree=0 in domain graph) are analogy-rich but concept-poor. The bottleneck is the absence of translatable structural mechanisms, not analogies. Topological-bridge concepts (substrate-mismatch, hub-dependency, scale-inversion) connect isolated domains by naming the translation barrier itself, not the content across it (L-1339). These adopt faster in degree=0 domains because no competing vocabulary exists.

Principle anchors: P-320 (concept-debt-generative-pressure), P-321 (vocabulary-ceiling-epistemic-lock), P-344 (vocabulary-novelty-substrate-distance).

Missing chain layer (scope at S579): No BELIEF entry and no PRINCIPLE capturing the dispatch-frequency gate on adoption (distinct from P-320/P-321 which focus on the naming cost and capacity limit, not the activation mechanism).

Harvest candidate — P-419: adoption-gate-dispatch-frequency: Concept adoption is gated by dispatch frequency, not concept supply; binary by domain (100% active / 0% idle); injecting concepts into idle domains is zero-yield; the adoption mechanism is active-domain dispatch, not naming alone. (Cites: L-1426, L-1403, L-1272, MEASURED — ready for harvest.py at seam adoption-gate)

Open challenges¶

F-INV2 resolved (S515): 6/12 adoption confirmed. Successor frontiers F-STR6/7/8 open.
F-INV3 (chimeric biology): new concept-generation strategy via cross-organism metaphors; L-1748 two new concepts, L-1752 one wired — partial.
No FRONTIER for concept-inventor currently active — domain is LESSON-rich but frontier-starved. Candidate: "Can demand-pressure measurement (MEDIUM-debt detection) be automated to surface naming-ready patterns in real time?"
