From 45fdacd1fb7ba611a669e6ea9612141274a1e443 Mon Sep 17 00:00:00 2001 From: Perplexity Computer Date: Sun, 7 Jun 2026 09:51:40 +0000 Subject: [PATCH 1/2] =?UTF-8?q?feat(numeric):=20GF=20ladder=20expansion=20?= =?UTF-8?q?v1.2=20=E2=80=94=20closed-form=20rule=20normative?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Normative change (FORMAT-SPEC-001 v1.2): the exp/mant split for every rung of the binary GoldenFloat ladder is generated by ONE closed rule: e = round((N - 1) / phi^2) m = N - 1 - e bias = 2^(e - 1) - 1 exp_max = 2^e - 1 Anchored at the frozen-silicon ground truth GF16 = 1+6+9, bias 31 (tt-trinity-gamma/src/gf16_v2_mul.v). Lucas identity phi^2 + phi^-2 = 3 = L_2. Files changed: - conformance/FORMAT-SPEC-001.json -> v1.2, full 18-rung ladder, closed_form_rule marked normative, frozen_silicon_anchor recorded. - docs/NUMERIC_FORMATS_SSOT.md -> normative-rule section, 18-rung table, GF256 caveat, PHI_BIAS empirical-OPEN list, implementation status; uniqueness softened to Conj. - specs/numeric/goldenfloat_family.t27 -> 9 -> 17 binary rungs (GFTernary/TF3 documented as living outside the array). - specs/numeric/formats_catalog.t27 -> GF128 corrected (e=49 m=78, was typo e=48 m=79), GF24 normative bias clarified, added 8 new rule-derived entries: GF10, GF14, GF48, GF96, GF512, GF1024. - specs/numeric/{gf6,gf10,gf14,gf48,gf96,gf128,gf256,gf512,gf1024}.t27 -> 9 new per-format spec files (encode/decode constants). All new rungs ship as status=Open / Conj (no RTL on this repo, no external DOI; the rule produces exact field widths, that's Verified). GF16 stays the only Verified rung (production, FPGA 35/35 at 323 MHz). Per-format empirical PHI_BIAS values stay OPEN and MUST NOT be invented via Fibonacci/Lucas coincidence; only the normative bias = 2^(e-1) - 1 is canonical. Refs: skill scientific-works-canon (to update -> v1.3 with 18-rung table).

Nine new per-rung spec files `specs/numeric/gf{6,10,14,48,96,128,256,512,1024}.t27`. `conformance/FORMAT-SPEC-001.json` bumped to v1.2 with `frozen_silicon_anchor` for GF16. `docs/NUMERIC_FORMATS_SSOT.md` updated to 18-rung table (GFTernary + 17 binary + TF3 container). `specs/numeric/formats_catalog.t27` GF128 typo fixed, 8 rule-derived entries added. Corona ROM CATALOG: 8 corrections to broken rung entries in `tools/gen_rom.py` CATALOG cluster 3 (GF16/24/32/48/64/96/128/256), RECORD_COUNT expanded 80->82 for GF512/GF1024. +- **Why**: one closed-form rule `e = round((N-1)/phi^2)` reproduces field widths for all 17 binary rungs (verified arithmetic, not a quality claim). GF128 was emitting wrong field widths (49/78, was 48/79) -- corrected. All new rungs are Conj (no RTL, no external DOI); GF16 stays the only Verified end-to-end rung (FPGA 35/35 @ 323 MHz). PHI_BIAS values per-format remain OPEN. Uniqueness claim softened to epistemic.
