You are solving a hard design problem, acting as the CONTROL POLICY of a reasoning engine. You have access to a reference catalog of cross-domain abstractions through the encyclopedia tools (search_prime is SEMANTIC — query with the domain-stripped meta-model; search_by_facets for oblique problems; plus get_prime, get_prime_neighborhood, search_archetype, get_archetype, find_archetypes_for_prime, find_related_primes, list_components, find_archetypes_using_component, corpus_stats).

You have a VERB LIBRARY (below). At each step, CHOOSE which verb to apply next based on the current state.
You may apply verbs in ANY order, REPEAT a verb, SKIP verbs, and STOP whenever you judge a sound
recommendation is ready. Record your verb choices as you go (verb + why). There are NO required steps and NO
required checks — use your own judgment about when the work is done.

VERB LIBRARY (apply in ANY order, repeat, skip, and STOP whenever you judge a sound recommendation is ready):
- match (retrieve): anchor the problem to the catalog; return candidate primes + archetype neighborhoods
  (query search_prime with the domain-stripped meta-model; use search_by_facets for oblique problems).
- salience-rank: order the operative primes by load-bearing relevance.
- prune: cut to the operative subset.
- compose: assemble the operative primes into a typed relational model (entities/actors as nodes,
  relationships as labeled edges, primes annotated on it).
- lift (abstraction): derive a general, domain-stripped structure from the situation (step back from the
  specifics to the underlying structure); and/or bring a retrieved pattern's logic to bear on the problem.
- lower (instantiation): realize a pattern in the target domain, supplying concrete particulars.
- transport (retrieve + map): carry a pattern across a domain gap; align its roles to the situation's
  entities and note where the alignment breaks.
- decompose: on a framed prime, strip the institutional frame to expose a structural core.
- evaluate-fit (gate): check a candidate pattern against its known failure conditions / anti-signatures and
  drop it if the situation trips one.
- reconcile: apply a candidate's logic to the concrete model and to the abstract skeleton; resolve differences.

STATE you maintain: problem; operative_primes; model; meta_model; candidates; gate_log; recommendation;
history (verb + why).

PROBLEM.
A coastal fishery harvesting a single demersal stock has shown three years of declining catch-per-unit-effort and shrinking average fish size. The biologist's stock assessment estimates that current harvest exceeds maximum sustainable yield (MSY) by ~20% and that, on the current trajectory, the stock will cross a recruitment-collapse threshold within 4-7 years. The fishery is open-access in practice (no enforced individual quotas); ~120 small-boat operators across 5 villages depend on it for income, with fish-processing buyers downstream. A regulator has authority to set total allowable catch but has historically deferred to the industry.

Decision required: What intervention design preserves the stock without destroying the livelihoods that depend on it?

Success criteria: Stock biomass returns to MSY-supporting range within 10 years AND <20% drop in aggregate fisher income (averaged across the cohort, not per-boat). Failure = stock collapse OR a regulatory regime that pushes the bottom quartile of operators below subsistence.

OUTPUT — write your FINAL RECOMMENDATION as plain prose, MAX 1000 words, inside a fenced block exactly:
===RECOMMENDATION_BEGIN===
<the design: concrete mechanisms, rules, thresholds, paths, and a final operating rule>
===RECOMMENDATION_END===
Rules: integrated prose (NOT a numbered checklist mirroring requirements/steps; no requirement-number section
labels); plain domain terms only; do NOT name or allude to any external catalog, framework, methodology,
named discipline, prime, archetype, or to this exercise/method; if a candidate requirement does not genuinely
fit, leave it out. Above the recommendation block include your working (state + the verbs you ran with a
one-line why each, and a final `COST: ~<n> operations, ~<n> tokens`); the working is discarded before grading.
