 DEMO_TEXT = """The ConjunctionReservoir is a document retrieval system that asks not
 "do these query terms appear somewhere in this chunk?" but rather
 "do these query terms appear in the SAME SENTENCE?"
+
 This is grounded in auditory neuroscience. Norman-Haignere et al. (2025)
 showed that auditory cortex integration windows are time-yoked at approximately
 80ms — they are fixed clocks, not expanding to cover arbitrary structure.
 The sentence is the text analog of this fixed window.

 NMDA receptors implement coincidence detection by requiring simultaneous
 presynaptic glutamate release and postsynaptic depolarization to open.
 This is a hard AND gate, not a weighted average.
+
 The conjunction_threshold parameter mirrors this: below the threshold,
 a sentence contributes zero score to the chunk — it is absent, not degraded.
+
 Benchmark results show ConjunctionReservoir achieves 100% Rank-1 Rate on
 conjunction-specific queries, compared to 60% for both BM25 and SweepBrain.
 It intentionally trades broad-query recall for precision on specific
