    "Weight storage and GPU computation precision are separate settings: with GpuOptions omitted (the runtime's default GPU precision) the s128 wfp16 graph compiled on the Galaxy S26 and returned finite logits, but no entities were extracted — the Kotlin block's comment reads 'default precision returns no entities' and HOST_CONTRACT.md 'Numerical and memory limits' says 'Explicit GPU FP32 computation is required; default GPU precision failed entity agreement'. Set GpuOptions(precision = CompiledModel.GpuOptions.Precision.FP32) on every GPU graph (card 'Kotlin'; HOST_CONTRACT.md).",
    "The graphs cover the encoder and the NER head only: the host looks up the word embeddings before the graph (host_assets/word_embeddings_fp32.bin, headerless little-endian float32 [128008,1024], 524,320,768 B, the default; or word_embeddings_fp16.bin, 262,160,384 B, upcast to float32 on lookup — gated at s128 only, longer-window fp16-table accuracy was not gated) and decodes the [1,1,T,15] start/end/inside logits with the upstream pairing decoder after it (threshold 0.5, flat spans). Build the encoded sequence with the pinned gliformer 0.1.2 processor ([SCHEMA] parent token, the five [ENTITY] label pairs, the separator, the text words; right-pad ids with 0 to N): a tokenizer call over a hand-concatenated prompt is not equivalent (HOST_CONTRACT.md 'Prompt, embeddings and routing').",
    "Bind the input buffers by name: the encoder's native buffer order is inputs_embeds [1,256,1024], attention_mask [1,256] (the flatbuffer signature map lists attention_mask first); attention_mask is 1.0 for real encoded tokens and 0.0 for padding; the sole output output_0 [1,1,256,1024] is the hidden state after the embedding LayerNorm and all 24 DeBERTa layers (absolute position embeddings disabled, exact relative-position bucket indices baked in) and passes unchanged to the head graph's encoder_hidden — the host does not gather (HOST_CONTRACT.md 's256', 'Prompt, embeddings and routing'; graph_contract_s256.json).",
    "Fixed windows and a fixed class axis: N = 128 (T = 48 text words) / 256 / 512 encoded tokens including the complete label prompt, exactly five labels in a fixed order (the measured order is person, organization, location, product, date; other five-label sets are accepted by the API but were not numerically gated), batch 1. Inputs above the s512 limits raise an error naming both capacities; nothing is truncated or chunked implicitly — chunk_by_sentences(text, max_words) is a caller-side helper whose entity offsets are local to each chunk (card 'Host contract'; HOST_CONTRACT.md 'One extraction call').",
    "s256 and s512 ship as an encoder graph plus a head graph because the single s256 graph does not compile on the LiteRT 2.2.0 GPU: the checkpoint's word-level BiLSTM is unrolled for T steps and unrolled heads of 6,286 operators or more crash the GPU compiler (the head crashes at 570 MB RSS — a runtime defect reported with reproducers, not a memory limit), while the DeBERTa encoder alone (1,773 operators) compiles at every window. Create two CompiledModels — the encoder with Accelerator.GPU and FP32 precision, the head with Accelerator.CPU — and pass the encoder's [1,1,N,1024] output buffer to the head as its first input; the numbers are exact either way, only the placement differs (card 'What you get', 'Kotlin').",
    "Memory is the cost of this model (Galaxy S26, native CompiledModel processes without the token table, tokenizer or decoder): the 707 MB s128 graph is 2,591,805,440 B resident after loading and peaks at 4,542,996,480 B while the GPU delegate compiles it; the s256 encoder on the GPU with the fp32 head on the CPU in one process is 4,571,271,168 B resident; the s512 head alone is 4,676,505,600 B resident on the CPU — so treat s256 as the practical top window in an app, chunk longer documents by sentence, and plan for flagship-class phones; the token table adds 262 MB (fp16) or 524 MB (fp32) when resident (card 'What you get', memory table).",
    "Cold start: the first call after process start took 5,023 ms (compile 4,708 ms) for the s128 wfp16 graph in a fresh native process and 80 ms afterwards; the Android sample warms the whole pipeline 12 times before Ready and reported launch -> Ready 4,775 ms and a first Extract tap of 168 ms (fifth 155 ms) in a non-debuggable build with the screen on (card 'What you get', 'Kotlin', 'Measured quality and performance').",
    "Returned start / end are Unicode code-point offsets into the original Python string (end exclusive; text[start:end] is the entity text), not UTF-8 bytes and not Kotlin UTF-16 indices — translate them when supplementary characters occur (HOST_CONTRACT.md 'Output decoding').",
    "Validation scope: GPU execution was validated on the Galaxy S26 (SM-S942Q, SM8850 Adreno, Android 16, LiteRT 2.2.0) only — other Android GPU families, lower-memory phones and NPUs were not evaluated; English only, one text per call, the NER path only (classification, relation, structuring and embedding heads are not converted); the quality figures are agreement with the official gliformer 0.1.2 fp32 implementation (micro-F1 1.000, 70/70 identical span sets on desktop CPU; 10/10, 15/15, 20/20 on the phone), not a human-labelled accuracy estimate; latency is a single-device sample at battery 30-41 C with the phone idle — the s512 encoder number was taken at 41 C (card 'Measured quality and performance', 'Provenance, conversion and license')."
