From bb3a67cc4a8a49ebf6f8e4faf7b74944e11f01f9 Mon Sep 17 00:00:00 2001 From: Dmitrii Vasilev Date: Sun, 9 Aug 2026 00:50:30 +0700 Subject: [PATCH 1/8] feat(numeric): register the GF-T ladder in the catalog SSOT, all nine rungs GF-T was absent from specs/numeric/formats_catalog.t27 entirely. The only id matching "gft" was gfternary, which is a different format -- a 2-bit {-phi, 0, +phi} alphabet, not the ternary-EXPONENT ladder. So the ladder had spec files for four rungs, no catalog rows, and no conformance packs, while a sibling repo's specs/gft.tri named this directory as its own source of truth. The rows and the five missing rungs are added here, where they belong. The ladder follows the width rule 1 + E_t + M = N, counting one position per trit -- the rule gft4, gft8 and gft32 already satisfy exactly. GF-T64 (7 trits, 56 bits), GF-T128 (8, 119), GF-T256 (9, 246), GF-T512 (10, 501), GF-T1024 (11, 1012) follow it. gft16 keeps its historical M = 9 and therefore 14 of its 16 positions; that gap is recorded rather than silently closed, because spending it invalidates the conformance vectors and the published silicon numbers. Two fields in the new rows need reading with care and the block comment says so. e= counts TRITS, not bits, with the bit-equivalent E_t*log2(3) spelled out in each row. And phi_distance, computed by the catalog's own |e/m - 1/phi| on that equivalent, rises toward 1/phi as N grows. That is structural, not a defect: GF sizes its exponent by e = round((N-1)/phi^2), which puts e/m at 1/phi by construction, while GF-T sizes its exponent for range and takes M = N-1-E_t. The two ladders optimise different axes and the field now makes that visible instead of implying GF-T is a worse GF. Conformance packs for all nine rungs are generated from the reference oracle. The probes are powers of two and 1.5*2^e chosen inside each rung's own exponent range, so every value is exactly representable in both the rung and f64 and every abs_error is exactly zero by construction -- no allowlist entries needed. An earlier attempt used fixed probes including 100.0, which GF-T4 cannot represent at all (its exponent reaches 4); the integrity gate caught it as undisclosed nonzero error, which is the gate working. Gates: catalog count SSOT == fresh regen == 92 (the paper's declared 84 was already stale at 83 before this change; the errata reminder now reads 92). WP-18 conformance integrity CLEAN. t27c typechecks all nine specs. Two of my own errors are worth recording. I first extended the derived zig-golden-float/specs/gft.tri instead of this catalog, though that file's own provenance field points here. And my regeneration filter matched the prefix "gft" and dropped gfternary from the pack index; the gate caught that too, after a baseline run on stashed changes showed it had been CLEAN before I touched it.

Anyone reading the document rather than the catalog would conclude the ternary-exponent ladder does not exist, and section 4 is precisely where that confusion is supposed to be prevented -- it already exists to keep TF3 and GFTernary apart. Section 4a adds the third object. GF-T is not a ternary alphabet: it is an ordinary binary-radix float whose exponent FIELD is a balanced-ternary integer. Only the encoding is ternary; the scale is a power of two. A format that scales by 3^e -- Ternary27 is the published example -- is a different design and measurably a worse one at equal width, by 0.33 positions per number, and the section gives the closed form. The table carries all nine rungs with the width rule, the range, the measured post-route figures where they exist, and an explicit "fits rule" column so GF-T16's two unallocated positions are visible rather than buried. Two columns are read wrong without help, so the section explains both. E is a count of trits; the bit-equivalent is given. And phi-distance rises toward 1/phi as N grows, which is structural: GF sizes its exponent by round((N-1)/phi^2), putting E/M at 1/phi by construction, while GF-T sizes its exponent for range. Without that note GF-T reads as a progressively worse GF, which it is not -- the two ladders optimise different axes. The section states what the fixed field buys and what it does not, because the second half is what keeps the first half honest. It buys the regime codec: 438 LUTs for a unary one, 40 for a length-prefixed one, 0 here, which through the measured area law A(M) = 141 + 2.4455 M^2 is 9.95 mantissa bits of silicon at the 16-bit class and 1.00 at M = 90. It does not buy unbounded range: by Kraft no prefix code on the integers beats l(e) = log2|e| infinitely often, so takum's regime is asymptotically optimal and nothing including GF-T beats it beyond GF-T's own range. The 2.83x and 5.46x hold inside that range and are marked as such.

That number has moved again, and for a different reason than last time. Last time was a miscount. This time GF-T -- the ternary-exponent ladder -- had zero rows in the catalog. The only id matching `gft` was `gfternary`, a different object entirely: a 2-bit {-phi, 0, +phi} alphabet, not a float with a balanced-ternary exponent field. Four rungs existed as .t27 specs with no catalog row and no conformance pack; five more did not exist at all. A sibling repository's specs/gft.tri named this directory as its own source of truth, so the ladder was being maintained downstream of a catalog that had never heard of it. Registering all nine rungs with their packs is the whole of the +9. Canonical count going forward is 92; both 84 and 83 are superseded. The amendment carries the cluster breakdown at 92 and states what did not change: no pack, SHA-256 or bit-exact vector from the 83 is affected, nothing was renumbered or re-hashed. The recommendation from June stands and this is the second time it has needed acting on. The paper's count is a constant in the gate rather than a derived number, which is exactly what lets the two drift; quote the live SSOT count with the commit that produced it, not a number frozen into a title.

Recovered from ff0b8de83; all nine specs now exist where the catalog says they do, and t27c typechecks each. gft16 then spends the two positions it was carrying unallocated. It used 14 of its 16: it inherited GF16's phi-optimal M = 9 and replaced GF16's six-bit exponent with four trits, and nobody re-spent what that freed. It was the only rung derived from its parent rather than from the ladder's width rule. Spent on mantissa rather than exponent, and the reason is a measurement rather than a preference. At this class the extra range is not consumed: quantised inference tensors span roughly 2^-14 to 2^14, and E_t = 4 already clips nothing at +/-40 binades -- 0 clips in 2000 values. E_t = 6 would have bought +/-364 binades at bit-identical error, which is range nobody spends at 16 bits. Measured effect: error 3.45e-4 -> 8.63e-5, a factor of 4.00 exactly as the precision law requires, since the exponent cancels and only M moves. Against takum16 the rung goes from 0.92x / 2.88x / 5.49x to 3.70x / 11.37x / 22.28x and stops losing the near bin. Silicon 372 -> 443 LUTs, +19%, at 131.73 -> 136.44 MHz: no frequency penalty. Conformance re-run in full rather than assumed: round-trip with sign 2000/2000, encoding monotone with 0 inversions, +/- symmetry 0/500 mismatches, lower boundary decodes. The gft16 pack is regenerated at M = 11 and a width_rule test added to the spec, so the position count is now asserted rather than remembered. All nine rungs satisfy 1 + E_t + M = N. Catalog count 92, WP-18 CLEAN, t27c clean.

GF sizes its exponent by e = round((N-1)/phi^2), which puts e/m at 1/phi by construction. This ladder sizes its exponent for RANGE and takes M = N-1-E_t, and its phi-distance RISES toward 1/phi as N grows -- it is maximally far from the phi split, not near it. The last tie to GF16 was an inherited M = 9, and that was severed when the 16-bit rung went to M = 11. Renamed throughout: specs/numeric/gft*.t27 -> tf*.t27, catalog ids gftN -> tfN, modules triformat_gftN -> triformat_tfN, conformance packs, INDEX entries, the numeric SSOT document and the erratum. The collision, and what I did to it. NVIDIA TensorFloat-32 held id=tf32 AND the filename tf32_conformance_v0.json. Its internal id moves to tensorfloat32 and its pack to tensorfloat32_conformance_v0.json; its human-readable name, "TensorFloat-32 (TF32)", is unchanged, because that is NVIDIA's name and not ours to alter. Only the internal identifier moved. I overwrote NVIDIA's pack during the rename before noticing, and restored it from git. The WP-18 gate caught it as a sha drift on tf32_conformance_v0.json rather than letting it through, and a second run caught that I had added a pack without bumping bitexact_packs in the index header. Both are the gate doing its job; I am recording them rather than presenting a clean sweep. One thing worth stating plainly: after this rename the catalog contains two formats whose short name reads TF32 -- ours and NVIDIA's. Their ids, files and display names all differ, so nothing is ambiguous to a tool, but a human skimming will need the context. That is a known cost of the name and was accepted deliberately. Gates: catalog count SSOT == fresh regen == 92; WP-18 CLEAN; t27c clean on all nine TF specs. specs/numeric/tf3.t27 still fails t27c with a type mismatch at line 255 -- that predates this change and is untouched.

Converting through the measured area law `A(M) = 141 + 2.4455*M^2`, whose derivative `λ = 4.891*M` is the marginal LUT cost of a mantissa bit, the unary regime is **9.95 mantissa bits of silicon** at the 16-bit class — more than -GF-T16's entire mantissa — and 1.00 at `M = 90`.

The area argument is therefore decisive against posit and weak against takum, and is stated that way rather than averaged. **What it does not buy.** By Kraft's inequality no prefix code on the integers has `l(e) < log2|e|` for all but finitely many `e`, so no format of unbounded range tapers more gently than one bit per doubling: takum's regime is asymptotically -optimal and **nothing, GF-T included, beats it beyond GF-T's own range**.

TEF removes the collision rather than working around it. NVIDIA keeps tf32, its filename and its name, and the pack is byte-identical to the pre-rename tree -- verified by SHA-256 against HEAD~1, not by inspection. Nothing of theirs moved. TEF -- Ternary-Exponent Float -- also says exactly what is true and nothing more. The exponent FIELD is balanced ternary; the radix is BINARY. That distinction is not pedantry: a genuine ternary-radix float, scaling by 3^e as Ternary27 does, measures 0.331 positions per number WORSE at equal width, so a name claiming a ternary radix would claim the one thing this format deliberately declines. "GF" failed in the other direction, claiming a phi-optimal lineage the ladder does not have. specs/numeric/tef*.t27, catalog ids tefN, modules triformat_tefN, packs tef*_conformance_v0.json, plus the numeric SSOT document and the erratum. Gates: catalog count SSOT == fresh regen == 92; WP-18 CLEAN; t27c clean on all nine TEF specs.

It is a different object -- a 2-bit {-phi, 0, +phi} alphabet, not a float -- that merely shares a prefix with the old GF-T names. The catalog row survived while the spec file did not, so nothing noticed. Restored from origin/master, byte-identical by SHA-256, and it typechecks. The same glob had already dropped gfternary from the pack index a few hours earlier. Twice is a pattern, so it gets a gate rather than more care. Renaming the ladder is not retracting its measurements. arXiv:2606.05017 and arXiv:2606.09686 cite GF-T, and it labels every published comparison against takum, tekum and posit -- those are the same nine rungs under a different name. former_name="GF-T{N}" now rides on every TEF row, and the catalog header states why, along with the two neighbours a bare gft* glob will swallow. tools/check_catalog_integrity.py asserts four things: every source= resolves; the three prefix-sharing neighbours are each present ON DISK, not merely as a catalog row; they are distinct families rather than aliases; and the former name survives. Verified red on each failure individually rather than green on the happy path -- removing gfternary.t27 exits 1 with MISSING, removing gf16.t27 exits 1 with DANGLING, and both go back to 0 when restored. A gate seen only green is not evidence.
