-|Adaptation stage|What is inherited|
-|---|---|
-|Grounded evidence QA|15,008 presentations through the selected ancestor|
-|Requested-field extraction|12,115 SNIPS requests|
-|Focused extraction plus replay|5,120 presentations|
-|Native JSON foundation|15,000 source/schema/JSON presentations|
-|Additional extraction SFT|2,048 inherited presentations: 1,536 TRAIN replay + 512 controlled cardinality views|
+The latest full-weight SFT jointly mixes original source/schema/JSON training replay, controlled multiple-value examples and authored natural-language passages across the seven SNIPS domains. The prepared corpus contains **21,144 presentations**: 15,000 original JSON views, 768 cardinality replay views and 5,376 controlled prose presentations (1,753 distinct new texts). The released main checkpoint inherits **19,200 presentations** from one deterministic shuffle: 13,640 original JSON views, 689 cardinality views and 4,871 prose views. It processes **6,153,194 serialized positions**, including **633,561 supervised assistant positions**. Later updates from the completed experiment are not included.
 
-The additional stage completed a 3,072-presentation experiment; the main checkpoint inherits only its selected 2,048-presentation prefix and 600,558 serialized positions. All stages update full model weights. The add-on uses batch 32/micro 2, fresh AdamW, 6-update warmup, peak 2e-6 and a 96-update cosine schedule toward 2e-7. On replay assistant tokens it adds KL from the frozen native JSON foundation; new rows use gold JSON CE alone. No teacher, RL, LoRA or adapter is needed at inference. Exact settings, data separation and stage hashes are in the report/provenance. Newly researched SGD/MIT datasets are not in these weights.
+The run uses full-weight BF16 compute with FP32-master AdamW, batch 64, microbatch 2, betas (0.9, 0.95), epsilon 1e-8, zero weight decay and gradient clipping at 1. A fresh optimizer warms up over 20 updates to 5e-6, then follows a cosine schedule toward 1e-6 over the full 331-update experiment. Only assistant JSON and the turn-ending token contribute to mean per-request token cross-entropy. There is no teacher KL, LoRA or RL in this latest stage. Source text, schema and instruction tokens are masked. The inherited earlier cardinality stage used training-only distillation; no teacher is used at inference.

 ## Limitations
 
-The model remains a focused SNIPS-domain extraction research model. Valid JSON does not prove correct values. It can invent, shorten, omit or misassign names, confuse venue/movie or state/country, and mishandle multiple values or nullable fields. For example, Bergen and Oslo can generate Bergen, Orange and Lake. Broader domains, long documents, corrections, arbitrary schemas, multilingual/chat/coding quality, calibration and prompt-injection robustness are unverified. `success` only means structure-valid natural completion. No blanket reliability/nonregression claim is made.
+A focused English extraction research model for documented flat schemas and mostly SNIPS fields. It can shorten, omit, invent or misassign values, confuse roles, miss list members, and fail on corrections or unfamiliar definitions. Valid JSON does not prove correct extraction. Long documents, nested objects, numeric/boolean outputs, multilingual tasks, general chat and prompt-injection robustness are outside the verified scope. `success` means structural validity and natural completion, not semantic correctness.

 ## 1. Current artifact and behavior
 
 The main checkpoint directly generates JSON from source text and a supplied JSON Schema. A single native autoregressive request emits the entire object. There is no fieldwise extraction-to-JSON assembler, answer repair, constrained decoder or gold-conditioned filling in the current inference path. Parsing and schema validation happen only after generation; the raw generated string is retained even when incorrect or invalid.

+### Latest joint JSON extraction SFT
+
+The latest full-weight SFT jointly mixes original source/schema/JSON training replay, controlled multiple-value examples and authored natural-language passages across the seven SNIPS domains. The prepared corpus contains **21,144 presentations**: 15,000 original JSON views, 768 cardinality replay views and 5,376 controlled prose presentations (1,753 distinct new texts). The released main checkpoint inherits **19,200 presentations** from one deterministic shuffle: 13,640 original JSON views, 689 cardinality views and 4,871 prose views. It processes **6,153,194 serialized positions**, including **633,561 supervised assistant positions**. Later updates from the completed experiment are not included.
+
+The run uses full-weight BF16 compute with FP32-master AdamW, batch 64, microbatch 2, betas (0.9, 0.95), epsilon 1e-8, zero weight decay and gradient clipping at 1. A fresh optimizer warms up over 20 updates to 5e-6, then follows a cosine schedule toward 1e-6 over the full 331-update experiment. Only assistant JSON and the turn-ending token contribute to mean per-request token cross-entropy. There is no teacher KL, LoRA or RL in this latest stage. Source text, schema and instruction tokens are masked. The inherited earlier cardinality stage used training-only distillation; no teacher is used at inference.
+
 ## 8. Prompt, schema and native inference
 
 Supply source text and a flat closed JSON Schema with 1–8 required fields. Supported properties are strings, nullable strings and arrays of strings. Every required key is returned; absent arrays target [] and absent nullable strings target null. Copy case/spelling and complete values; preserve source order. Nested schemas, numbers/booleans, enums and advanced constraints are outside the verified runner contract. The supplied runner rejects overlong inputs without truncation.
 
 The fixed instruction is followed by compact `{"source_text":...,"schema":...}` and native SFT role tokens. It issues exactly one autoregressive whole-object generation with temperature 0, repetition penalty 1 and at most 256 output tokens. No fieldwise assembly, repair, schema-constrained decoder, normalization, reference answer, frozen teacher or secondary model is used at inference. Parsing/schema checks only annotate the raw generated text afterward.
 
-## 9. Evaluation protocol and selection
-
-The continuation checks 404 fixed development requests plus 54 local playground fixtures at its scheduled checkpoints. DEV contains 252 original native JSON controls, 64 previously observed combined-request controls, 8 earlier single-request probes, 32 earlier authored list controls and 48 new cardinality controls. Metrics include exact requests/fields, precision/recall/F1, present/missing fields, false/missed abstentions, unsupported values, strict parsing, schema validity, stopping/budget failures, paired requests and cardinality-group correctness. These panels have prior research exposure; no new blind/general extraction benchmark claim is made.
+## 9. Evaluation and release selection
 
-The main checkpoint is an owner-selected research tradeoff. Strict automatic retention gates did not pass: some domain/variant unsupported values and nullable false abstentions increased. The run's automatic best pointer remains its starting baseline; the published main is explicitly the selected trained checkpoint, not a claim that the automatic gate accepted it. Larger original TEST comparison was performed after the candidate was nominated from development/playground results. Subsequent owner release choice observed that comparison. The original 1,444 panel also has earlier research exposure.

Previous release outputs were identity-checked and rescored from their saved cache. The main checkpoint generated every request, with no dropped cases or token limits. Complete correctness requires natural stopping, strict JSON/schema validity and exact field/value/order agreement. Value scores use(field, value) multisets; literal unsupported-value checks do not detect every wrong association.
+The separate observed 60-case playground scores **49/60 (81.67%)**, compared with 45/60. Its original 54-case subset scores 46/54; the six added three/four/five-item probes score 3/6. Three larger-list probes still fail. The compact 240-request development panel scores 178/240 (74.17%). These panels measure different scopes and must not be pooled. They have prior research exposure and are not fresh blind benchmarks or an external leaderboard.

+The main checkpoint was selected for aggregate improvement despite failing the strict zero-lost-case development gate. Individual regressions remain; improved aggregate scores do not establish universal retention or production reliability.
 
-Complete requests increase 1,191→1,199/1,444 (+8).27 previously wrong requests become correct and 19 previously correct become wrong; those 19 schema views cover 18 unique source texts. Paired source correctness increases 501→512/694. Unsupported values 30→27; false abstentions 111→107; missed missing fields 115→110. Strict parsing remains 1,442/1,444 and schema validity 1,441/1,444. These modest aggregate gains coexist with small F1/precision/recall decreases.

+Greedy temperature 0, repetition penalty 1, maximum 256 output tokens and the unchanged native serialization. Every request supplies only the source text, schema and fixed extraction instruction. References, gold spans and offsets are used after generation only. No prompt truncation, constrained decoding, secondary model, JSON assembly or repair is used. Strict parsing rejects duplicate keys and nonfinite constants. Complete correctness requires a natural stop, valid JSON and schema, and exact agreement of all fields. Lists retain order; value precision/recall/F1 compare extracted values, while field accuracy includes missing fields. The full machine-readable result includes counts, denominators, paired correctness, unsupported values and stopping metrics.
 
-Local field accuracy 124/135(91.85%); value precision 89.53%, recall 91.67%, F190.59%; missing 49/53(92.45%); unsupported values 3; all 54 stop naturally. Local precision declines from 91.03% despite higher recall/correctness. The new 48-pattern panel has only 36/48(75%) schema-valid outputs. All panels remain separate; do not pool them or claim an external leaderboard result.
+The 1,444 requests comprise the original canonical and schema-stress views; some views reuse the same source. Previously observed tests and playground examples informed research and owner selection. They are not a fresh blind holdout. Synthetic prose shares construction families and training entities, so gains do not establish open-domain generalization. The selected checkpoint is a preserved no-pruning replay artifact identified by its exact hash; metrics are recomputed from that artifact's saved generations, not borrowed from an earlier artifact. No claim of bitwise training replay identity is made.
 
 ## 10. Failure audit and limitations
 
-All 19 newly regressed original TEST requests are schema-valid JSON. Manual primary categories: 4 changed/invented values, 3 shortened spans, 8 wrong field assignments, 2 omissions and 2 especially ambiguous source/schema contracts. Examples include Pete Murray becoming Peanut, a complete movie title losing its final phrase, a venue assigned as a movie, and an explicit city becoming null. A bare music title may not specify track versus album; broad entity_name definitions also conflict with exclusive annotation roles. Those ambiguity flags do not change benchmark golds or excuse clearer errors. Full-case evidence is retained in the report archive.
-
-Multiple-value coverage improves, but errors remain: Bergen and Oslo can generate Bergen, Orange and Lake. Correct JSON structure cannot establish correct extraction. The model is primarily SNIPS-domain research software; unfamiliar fields, long documents, corrections/associations, nested schemas, arbitrary-schema reliability, general chat/coding, multilingual behavior, confidence calibration and prompt-injection robustness remain unestablished. No 95% reliability or universal release-readiness claim is made.
+There are 173 entirely incorrect original-test requests and 24 previously correct requests become incorrect. Errors include incomplete copying, wrong roles, missing or extra values and unsupported values. All seven domain totals improve, but per-request retention is not perfect. On the six longer-list probes only three are correct. Flat schema validity is 100% on this test, not a guarantee for arbitrary prompts, schema types or novel domains. No general chat, reasoning, code, multilingual, long-document or safety readiness claim is made. The authored development panel is small and repeatedly observed.
 
 ## 11. Packaging, verification and reproduction
 
-The main package retains BF16 weights, frozen tokenizer and native MLX architecture. Stock-MLX standalone verification compares all 54 raw outputs and stop reasons against the selected saved playground protocol; the receipt specifies achieved coverage/parity and correctness. This is packaging parity, not a fresh blind accuracy estimate or complete 1,444-case cross-runtime parity claim.
+The main package uses BF16 weights, the unchanged tokenizer and the supplied native MLX runner. The verification receipt records stock-MLX raw-string and stop-reason parity on all 60 observed playground fixtures. This establishes packaging parity within the stated scope, not full 1,444-case cross-runtime parity or an independent benchmark. Standard `model.safetensors` and the public model ID remain unchanged. Previous Hub and Git revisions retain rollback identities.
 
-Hugging Face supplies canonical model.safetensors, config, tokenizer, launcher, native_bundle.zip and model/report/results/provenance records. GitHub ships runnable source, curated JSONL records, preparation/training/evaluation code and audit evidence. Optimizer/packed-array binaries, private workspace paths, credentials and host network logs are excluded. Original workspace manifests record excluded files; provenance/SNAPSHOT_MANIFEST.json lists the actual shipped source inventory. Sanitized metadata hashes are separate from original metadata hashes.
+The source archive includes the frozen latest training recipe, prepared JSONL corpus and input hashes, exact prefix counts, saved generated answers, scorer and matched parent comparisons. Public copies sanitize private workspace paths and distinguish original from distributed hashes. Optimizer binaries and packed pretraining pools are omitted. Reproduction requires the specified parent and layout, compatible dependencies, and fresh local preflight receipts; sanitized audit receipts are not resumable optimizer state. See TRAINING_AND_REPRODUCIBILITY.md, provenance/LINEAGE.json, results/JSONLITE_RESULTS.json and pretraining/native_json_128/ in the archive.
 
-The additional stage has frozen paths to historical baseline receipts and prepared-data inputs. Reproduction requires the specified parent weights, original source dependencies/layout, re-packing omitted arrays and regenerating local preflight receipts; published audit receipts are not ready-to-resume optimizer state. Native inference needs none of those training dependencies. The teacher is only used during training.
+## 12. Attribution and licensing
 
-See provenance/LINEAGE.json, results/JSONLITE_RESULTS.json, pretraining/native_json_105/, examples/cases.json and reports/model-design/SFT-105_cardinality_distillation_20261014/ inside the source archive. Prior native JSON release hashes/revisions remain in provenance/RELEASE_HISTORY.json; old Git/Hub revisions remain accessible.
