Numeric Conformance Packs (Trinity S3AI / t27)

Version: v2.0 (2026-06-10). License: MIT. Maintainer: Trinity S3AI -- admin@t27.ai -- ORCID 0009-0008-4294-6159. Mirror of: gHashTag/t27 conformance/ and specs/numeric/ subtrees. Companion dataset: playra/numeric-format-catalog (the 80-format ruler this pack instantiates). Linked papers:

TL;DR

Bit-exact conformance vectors for the GoldenFloat (GF) family of phi-structured floating-point formats, plus two reference packs (phi_identity, phi_ratio) that exercise the canonical phi^2 + phi^-2 = 3 identity. The packs let any third-party kernel implementer check binary-level conformance with abs_error instead of "looks close in plots".

Quick start

from datasets import load_dataset

# Pull a single pack
gf16 = load_dataset("playra/numeric-conformance-packs", "gf16", split="vectors")
print(gf16.column_names)

# Verify round-trip on one vector
sample = gf16[0]
hex_bits   = sample["bits_hex"]
expected   = sample["f32_value"]
# Your decoder under test:
recovered  = your_gf16_decoder(int(hex_bits, 16))
abs_error  = abs(recovered - expected)
assert abs_error <= sample["tolerance"], f"GF16 conformance violated: {abs_error}"

The full call-and-response contract is documented per pack in manifest.json.

Provenance

This dataset is a mirror, not a primary source. The primary source of truth is the t27 repository:

  • Specs: gHashTag/t27 -> specs/numeric/ (.t27 SSOT files)
  • Conformance generators: gHashTag/t27 -> conformance/ + tools/gen_*.py
  • Frozen silicon anchor: GF16 is validated end-to-end against the TTGF26a / GF180MCU tape-out (35/35 vectors at 323 MHz, see arXiv:2606.09686 Section 6).

Every JSONL row carries:

  • format_name, format_bits, format_spec -- canonical identity
  • bit_layout / format_spec -- exact field widths
  • seal -- SHA-256 of the row payload for tamper-evidence
  • formal_proof (where applicable) -- Coq lemma name in coq/Kernel/*

How this fits the wider ruler

These packs sit at Tier 1 of a three-tier numeric-format corpus:

  • Tier 0 SSOT: specs/numeric/formats_catalog.t27 (machine-checked, 83 rows live)
  • Tier 1 Portable JSON packs (this dataset)
  • Tier 2 Silicon-validated ROM: tt-trinity-corona 80-format ROM + 19 RTL decoders + 5-layer dossier (TTGF26a / GF180MCU tape-out)

The companion dataset playra/numeric-format-catalog carries the full 80-format catalog with cluster, bit-width, and phi-distance metadata.

Considerations for using the data

Recommended uses

  • Verifying a third-party GF or phi-arithmetic kernel against a fixed reference
  • Cross-checking custom GoldenFloat decoders during silicon bring-up
  • Teaching: bit-exact rounding behaviour for non-IEEE phi-structured formats
  • Audit and reproducibility studies of phi-structured arithmetic

Out of scope

  • IEEE P3109 OFP8 -- cross-walk is documented in p3109_crosswalk.json (mapping only) but not a primary distribution here
  • NF4 / NF8 (NormalFloat) -- adjacent quantisation formats, not covered
  • MXFP4 / MXFP6 -- OCP mixed-precision wrappers, see arXiv:2606.09686 Section 4 for the cross-walk
  • Posit / Takum / LNS -- alternative number systems are catalogued in playra/numeric-format-catalog but no conformance pack here
  • Mixed-precision GEMM -- this is a per-format conformance dataset, not an end-to-end kernel benchmark

Known limitations

  • Pack size is uneven by design. Several packs ship 1 row (anchor); others ship 34-37 rows (sweep). The number of rows reflects how the format is tested in the kernel, not its importance.
  • abs_error only. PCC, FID, and other distributional metrics are explicitly out of scope; this is a pointwise conformance dataset.
  • GF dominance. Reflects the maintainer's research focus. For SOTA AI quantisation formats (NF4, MXFP4, posit), this dataset is not a substitute for OCP or open-compute reference implementations.
  • Single-language schema. All vectors and manifest are English-only. No localisation.
  • No social-bias dimension. Numeric format conformance is not a fairness-sensitive task; if you're using these vectors as part of a downstream model evaluation, fairness considerations live at the model level, not here.

Known biases

  • Equal weight per cluster. The pack distribution mirrors the maintainer's research priorities; it is not a representative sample of the AI accelerator format population.
  • Phi-structured emphasis. All formats with the goldenfloat tag are designed around the closed-form rule e = round((N-1)/phi^2). This is by construction, not a discovered property.

Maintenance and changelog

Date Version Change
2026-04-07 v1.0 Initial 10-pack release
2026-06-10 v2.0 Updated with audit-disclosed schema, SHA-256 manifest, anchor preprints
2026-06-13 v2.1 Added catalog preprint cross-link (arXiv:2606.09686), README upgrade per FAIR / Datasheets / Data Cards

Update cadence. No fixed cadence. New packs are added when (a) a new GF rung is verified, or (b) a new conformance contract is requested via gHashTag/t27 issues. Existing rows are immutable; if a format spec changes, the row is replaced and the SHA-256 manifest tracks the diff.
