sezgi 0.1.6

Mixed-space hybrid auto-dispatch widened to 17 presets: ParticleSwarm and MothFlameOptimization join the list (since 0.1.6), and DifferentialEvolution(variant = "jde") is now allowed on mixed spaces (float blocks keep the preset's own generator, GA variation on discrete blocks; a space with no float block is all GA).
Engine: gen/pso, gen/de-jde and gen/mfo now own their state (PSO velocity/pbest, jDE per-individual F/CR, MFO flame memory) and are on the gen/compound self-contained allow-list. The companion components (replace/pso-commit, adapter/jde-commit, adapter/mfo-flame-update) are kept for spec compatibility; their state duties moved into the generators. Single-block preset runs are bit-identical to 0.1.5.
Still excluded from hybrid dispatch (structural): shade/lshade, cmaes (+ ipop), abc, sa, harmony_search, nelder_mead, hho.

Mixed-space hybrid auto-dispatch widened to 15 presets: GravitationalSearch and BatAlgorithm join the list (float blocks keep the preset's own generator, GA variation on discrete blocks; a space with no float block is all GA).
Engine (gen/compound): every block now owns a nested blackboard stored in the parent blackboard under cmp{i}/bb, so self-contained stateful generators keep per-block state. An allow-list (SELF_CONTAINED_COMPOUND_KINDS: gen/gsa, gen/ba) admits them; other stateful generators (PSO, CMA-ES, SHADE, ...) stay rejected. Existing stateless compound specs are bit-identical.

Mixed-space hybrid auto-dispatch widened to 13 presets: AntLion and EvolutionStrategy join the 0.1.3 list (float blocks keep the preset's own generator, GA variation on discrete blocks; a space with no float block is all GA). SimulatedAnnealing stays ineligible: its fixed population of 1 cannot host the GA discrete sub-generators.
Engine: the post-adapter genotype shape sweep now runs only for stages that have an adapter.
New R guard tests for .sz_hybrid_wrap_stages (malformed preset specs).
The ineligible-preset error now lists the real preset names (cuckoo_search, alo, es_mu_plus_lambda) instead of "cuckoo-search".

gen/compound now accepts any registered sub-generator that is eligible (stateless, pop-to-pop, no internal evaluation, no nesting) instead of a fixed GA-only table; ineligible kinds are rejected with the reason.
Mixed-space auto-dispatch for 11 presets: DifferentialEvolution (rand_1/best_1), GreyWolfOptimizer, WhaleOptimization, SineCosineAlgorithm, JAYA, GrasshopperOptimization, SalpSwarm, FireflyAlgorithm, FlowerPollination, TLBO, CuckooSearch. The result is a hybrid: the preset's own generator on float blocks, GA variation on binary/int/categorical/permutation blocks. A space with no float block gets zero preset-specific variation (all variation is GA).
New shape guards: the evaluator panics with "genotype shape mismatch:" on a mis-shaped genotype, and the engine re-checks genotype shape after the adapter step.
The multi-block engine error hint now mentions eligible non-GA generators inside gen/compound.
Presets that cannot ride inside gen/compound (stateful, one-offspring, internal-evaluation) raise an error naming why on a mixed space.

GeneticAlgorithm now auto-dispatches multi-block single-kind spaces (e.g. several Float blocks) through gen/compound; mixed-kind spaces still raise. Other flat presets run on a multi-block space now fail fast with an engine genotype-shape error instead of silently corrupting.
