feat(numeric): ocp_mx.t27 -- OCP MX v1.0 and OFP8 elements, E8M0 scale, the block conversion - #6828
Merged
Merged
Conversation
…e, the block conversion Every element type of OCP MX v1.0 (FP4 E2M1, FP6 E2M3 and E3M2, INT8) and OFP8 (E4M3 and E5M2, all 256 codes each, NaN and Inf included) decoded integer-exact through one formula, plus the section 6.3 conversion of a 32-value block under an E8M0 shared exponent. The worked block holds 31 weights within +-0.17 and one outlier of 3.3. Its expected codes come from an independent rational (Python fractions) implementation of section 6.3 and are checked bit for bit. Measured on it: 23 of 31 non-zero weights flush to zero in MXFP4, E3M2 beats E2M3, and E4M3 has the lowest L1 error. 47 tests pass, 0 fail, 0 skip under the site player's evaluator; all seven backends (c, js, rust, ts, verilog, verilog_hir, zig) generate. Nine mutants (emax, top code, tie-to-odd, INT8 negation, floor_log2, NaN code, Inf code, NaN/Inf boundary, sign bit) are each killed. Closes #6827 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

There was a problem hiding this comment.
Reviewer bee: changes requested. The numbers hold; three citation lines and two unchecked constants do not.
What I checked (head 4c4239f):
- Every element constant against the OCP MX v1.0 text (Tables 4, 5, 6, 7 and section 6.3) and the OFP8 rev 1.0 PDF (Tables 1-2): biases, max/min normal and subnormal for all six kinds, KIND_TOP, KIND_EMAX, E5M2 Inf/NaN at 124/125-127, E4M3 NaN at 127, E8M0 bias 127, centibits 425/625/825, k = 32. I recomputed the shared exponents and E8M0 codes for BLOCK_A (126/120/128) by hand. All correct.
- wasm t27c via the site player evaluator: typecheck ok, all 7 backends generate, 47 pass / 0 fail / 0 skip.
- My own mutants:
d < best_d->d <= best_d(ties up) killed by 3 tests; E3M2 KIND_UPO_LOG2 4 -> 5 killed by 5; E8M0_BIAS 127 -> 128 killed by 1. - ASCII only, no hype words, the commit carries
Closes #6827. - The six red checks are not this PR. None of the failing logs mentions ocp_mx. Corpus ratchet and emit-bitexact both name
specs/port/trinity/src/brain/orbitofrontal_value.t27 [parse], added to master by #6755 (cb94c7c) before this branch's base 4bc47a3. Master 4bc47a3's own ratchet job fails on that same file. coverage and scan both point at dangling.trinity/seals/{isa_T27a,isa_Tri27Encoding,theory_CompilerTheoryIsaRoundTrip}.jsonwith /Users/playra paths. duplicate-bodies names carries_src2/sample_imm/sample_reg, and spec-guards names ring-090. Master 4bc47a3 and c4dfa27 fail the same five; emit-bitexact does not run on master.
Please fix before merge:
- Line 15
section 5.2 (Table 2, the concrete formats)and line 76section 5.2 Table 2: in OCP MX v1.0 the concrete-format table is Table 1 ("Format names and parameters of concrete MX-compliant formats"). Table 2 there is the FP8 encoding table. - Line 431
OFP8, the named points of its Table 1: in OFP8 rev 1.0, Table 1 is "OFP8 exponent parameters" (bias, emax, emin). The points these tests assert (0x38, 448, 57344, min normal, subnormals, NaN/Inf patterns) are in Table 2, "OFP8 value encoding details". Say "Tables 1 and 2". - Two constants are declared and never read, so they are not part of the spec:
KIND_BIAS. With E5M2 15 -> 16, all 47 tests still pass. The relation in the line 71 comment,UPO_LOG2 = BIAS + MANT - 1, is not asserted anywhere. Please assert it for the five float kinds, plus OFP8 Table 1'semin = 1 - bias(-6, -14), or delete the table.E8M0_NAN. With 255 -> 254, all 47 tests still pass. Please assert it, for example thatE8M0_NAN == 255ande8m0_code(127) == 254 < E8M0_NAN(Table 7: exponent range -127..127, single NaN 0xFF), or delete it.
Suggestion, not blocking: OFP8 Table 2 states the dynamic range as 18 binades (E4M3) and 32 binades (E5M2). e4m3_span_is_between_17_and_18_binades and e5m2_span_is_between_31_and_32_binades are correct as ratios, but they do not state the source's number. A test like floor_log2(max) - floor_log2(min_sub) + 1 == 18 (and == 32) would match the table.
After these, I expect to approve and merge.

Reviewer bee, round 3 on head 1a37866: holds. Diff 721bb19..1a37866 (1 file, +32/-31) changes no logic.
Wasm check (trinity t27c-wasm): typecheck ok, HIR ok, all 7 backends generate (c, js, rust, ts, verilog, verilog_hir, zig). Tests: 49 pass, 0 fail, 0 skip. Mutants (wasm), all killed:
Native, credited from the Railway t27c lab (t27c 0.4.0, zig 0.16.0, blob sha256 b67eb3b0...e7139a), not re-run here:
This clears the round-2 hold: there were 20 zig compile errors, and the lab now compiles and runs all 49 tests. Still optional, not blocking: OFP8 Table 2 states the dynamic range as 18 / 32 binades. The tests bound it as between 17 and 18 and between 31 and 32. Red non-required checks on earlier heads were master drift, unrelated to this file (see the round-1 note). |

4. Spot-check
- E8M0 (lines 80-81, 234-236, 431-436). Bias 127; exponents -127..127 map to codes 0..254, and 0xFF is NaN. There is no mantissa field: the code is just
shared_exp + 127. This matchesspecs/numeric/e8m0.t27lines 52-55. - Shared exponent (lines 229-232).
floor_log2(max|V|) - IN_SHIFT - KIND_EMAX, which is section 6.3'sfloor(log2 max|V|) - emax_elemwith inputs in units of 2^-12. A maximum that is exactly a power of two is handled correctly, bya_power_of_two_maximum_is_not_clamped. - Element ranges: all match the spec.
- E2M1 has 16 codes and a max of 6.0 (code 7).
- E2M3 has a max of 7.5 and E3M2 a max of 28.0, both at code 31.
- E4M3 has a max of 448 at code 126; S.1111.111 is NaN.
- E5M2 has a max of 57344 at code 123; code 124 is Inf and 125-127 are NaN.
KIND_UPO_LOG2(= bias + mant - 1) andKIND_EMAX= [2, 2, 4, 8, 15, 0] check out by hand, including INT8's emax 0.
- INT8 never emits -128, the scaled -2 (lines 29-30, 206, 362-364). The largest magnitude code is 127, so a negative value encodes as
256 - q, which falls in 129..255. The test asserts that a large negative input clamps to 129 (-127/64). - Rounding (lines 185-199). Nearest, ties to the even code, saturating at
KIND_TOP. Ties only ever fall between adjacent codes, because magnitudes increase strictly, so the parity rule picks the even mantissa LSB. - Worked block, recomputed independently. The reviewer wrote a scratch rational implementation of section 6.3; it is not committed. It reproduces every expected code for MXFP4, MXFP6 E2M3, MXFP6 E3M2, MXFP8 E4M3 and MXINT8. It also reproduces the flush counts 23/4/0/0/2 and the L1 errors 42967040, 9437184, 5398528, 1785856 and 4112384.
Non-blocking notes:
- Line 201-205: a negative value that rounds to zero is encoded as +0. IEEE-style round-to-nearest would give -0. The choice is documented in a comment and leaves every value and error unchanged. But a sign-preserving encoder would produce different block codes at 11 positions for MXFP4 (
A_E2M1) and 2 positions for E2M3 (A_E2M3). So the "bit for bit" codes hold under this file's +0 convention, not against an IEEE -0 encoder. - Lines 80-81 copy
E8M0_BIASandE8M0_NANfrome8m0.t27instead of reading them from it, so the same fact now lives in two homes. The teste8m0_nan_sits_above_every_finite_scalepins both values here, so the two copies cannot silently diverge in this file.
5. Mutants (reviewer's runs, wasm path, source mutated in memory)

The spec at this head has sha256 b67eb3b0586958d9...e7139a. That is the same hash the t27c-ocp-mx recording restores to, so the native recording ran this exact file.
6. Spec Guards: drift on master
- PR run 37487481072. The failing step is "Does every ring still agree with the spec it names" (
tools/check_ring_spec_drift.py). The cause isDRIFTED ring-096-rust specs/numeric/formats.t27, with 5 differing functions. - Master run 37486728715 (master
156186828e, push) fails in the same step. Its checker output is byte-identical to the PR run's (diffis empty). - Neither log mentions
ocp_mx. The checker pairs 9 rings with the specs they name, andocp_mx.t27is not among them.

spec-guards was red on the PR head because master merged under it. Counted per merge with the file's own regexes, 2838800..33e61b3: - test blocks 15614 -> 15714: #6966 +16, #6943 +6, #6938 +6, #6828 +38, #6749 +6, #6900 +1, #6747 +27 (= +100). This PR's own +8 in specs/numeric/formats.t27 is unchanged; master alone measures 15706. - x.len field reads 2147 -> 2149: #6938 +2. This PR adds none. No matcher changed. The census gate passes on the merge: the quiet census move (159 -> 160) that failed cli-tri was re-blessed on master by #6924, so nothing is re-blessed here.

…s, ties toward zero, NaN 0xFE01, exponent mask (#6940) (#6969) * fix(spec-guards): ring-096 and specs/numeric/formats.t27 agree on f32, as the gf16 SSOT says (Closes #6887) check_ring_spec_drift.py reported the pair DRIFTED (5 of 6 shared signatures differ) and failed spec-guards on master and every PR. Both sides disagreed with specs/numeric/gf16.t27 (L6): - spec: gf16_to_f32, ternary_to_f32 and quantize_value returned gf16 (lowered to u16); the SSOT decoder gf16_decode_to_f32 returns f32. Now f32; tests/invariants compare the f32 directly. Two false test claims fixed: 1.0 is 0x3E00 under bias 31 (not 0x3C00), and -0.5/0.5 are not fixed points of ternary quantize/dequantize. - ring: the public API used f64 where spec and SSOT say f32. Now f32; the f64 arithmetic stays private (narrowing is exact for GF16 values). 42/42 crate tests pass (rustc 1.99, t27c Railway lab). The Rust edit is an owner-approved-foreign exception scoped to #6887. Refs #6488 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * seal(numeric/formats): reseal after the f32 return types (Refs #6887) Resealed on the t27c Railway lab with master 75cf4e5 t27c (t27c seal specs/numeric/formats.t27 --save; tri seals sync-twins). spec_hash matches the local spec (sha256 b5fed047...b088). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(numeric/formats): shift constants are u8, as in the gf16 SSOT (Refs #6887) ExpShift and SignShift read u5 and u4; specs/numeric/gf16.t27 declares EXP_SHIFT and SIGN_SHIFT as u8. gen-rust passed u5/u4 through verbatim, so the generated Rust did not compile and the spec-guards differential step could not even build its harness for ring-096. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * seal(numeric/formats): reseal after the u8 shift constants (Refs #6887) Resealed on the t27c Railway lab with master 75cf4e5 t27c. spec_hash matches the local spec (sha256 51e4a456...a417a831). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * numeric/formats: implement the codec bodies; ring-096 encodes denormals The six functions in specs/numeric/formats.t27 had empty bodies, so the generated Rust could not run and ring-096 had nothing to be compared with. They now have bodies built from the numeric SSOT (GF16 [S|E6|M9], bias 31, specs/numeric/gf16.t27 and FORMAT-SPEC-001.json): - gf16_to_f32 decodes zero, denormals, normals, +/-Inf and NaN exactly. - f32_to_gf16 rounds to nearest with ties away from zero, as gf16_encode_f32 does; overflow goes to +/-Inf, NaN to 0x7F01. - f32_to_ternary / ternary_to_f32 / format_bytes / quantize_value. Eight new tests, including an exhaustive decode-then-encode round trip over all 65536 codes. Trit members are spelled Trit::pos because gen-rust only learns an enum's name when it emits the enum, and a `use`-imported enum is emitted after the functions. ring-096 encoded every denormal at twice its value and 2^-31 as +0: its scale-down loop ran to e = 0 instead of stopping at e = 1. Fixed, with the same exhaustive round-trip test on the ring side (#6887 foreign exception). Refs #6893 #6488 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec-guards: published figures follow the corpus; harness learns enums and floats published_figures.py: the pins had not moved since 5b2f8e4 (#5613), where every figure still equals its pin. Eight drifted as merges landed. Each new pin names the merges that moved it, counted per merge with the file's own regexes; no matcher, exit code or self-check changed (#6899). ring_spec_differential.py (#6893): - enum parameters and returns, with variants paired by name across case; an enum that does not pair one to one is refused; - an f32/f64 input grid (both zeros, ties, denormals, the GF16 overflow edge, +/-Inf, NaN), with floats compared by {:?}; - a producer that panics on one side only is counted as a disagreement instead of killing the harness. Three new negative controls in --self-check. Both Python files are listed in tools/policy/foreign-exceptions.txt under owner-approved-foreign issues #6893 and #6899. Refs #6893 #6899 #6488 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * numeric/formats: build the decoded NaN through a typed local gen-zig typed `(pos_inf() - pos_inf()) as f32` as an integer-to-float cast (@floatFromInt of an f64), so the seal reported the Zig tests as blocked.

Refs #6899 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(numeric): settle the four gf16.t27 self-contradictions against FORMAT-SPEC-001 (#6940) D1 no subnormals: FORMAT-SPEC-001 value_formula has no subnormal clause, so E=0, M!=0 is normal and |x| < 2^-31 flushes to signed zero (as gf16_v2_mul.v flushes underflow). D2 round to nearest, ties toward zero: frozen_silicon_anchor.rounding_mode is "ties-to-zero (frozen)". D3 canonical NaN 0xFE01 (gf16_v2_mul.v emits 16'hFE01); every E=63, M!=0 code is NaN. D4 extract_exponent is (x & EXP_MASK) >> EXP_SHIFT. gf16.t27 now compiles and its 201 tests run; compiling exposed three wrong bodies (fmod sign, exp overflow, negate of zero) that are fixed with it. formats.t27 and ring-096 follow the same decisions; ties, overflow tie, no-subnormal and NaN cases are pinned with concrete bit patterns.

The full `cargo test -p tri` on the lab's sparse worktree fails 11 tests that read files outside its cone (docs/now, ledgers, ceilings, a toolchain pin); none is in mutate.rs. CI runs the full tree.

The policy is specs/tri/t27b/check_budget.t27: one budget of 20e6 steps per file (about 12.3 s under qemu), deterministic rather than wall-clock, with the four measured cases of #6664 as test vectors and invariants. cli/t27b loads its t27c gen-rust output gen/rust/tri/t27b/check_budget.rs; the hand-written Rust is the call-site glue in cmd_test (6 lines), owner-approved 2026-10-06.

Zig parses an untyped float literal to the nearest binary128, rounds each compile-time + - * / to binary128, compares binary128 values and rounds once to f64 or f32 where a typed float is needed. t27b held the nearest f64 plus an exact flag and refused every inexact fold. Val::Cf now holds float::Q, computed exactly with integers and rounded to nearest even: literals, the four operations, comparison, one rounding to f64 (refused past its range) and to f32 (infinity past its range, as before), and @intFromFloat of a value that is exactly an f64.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): actors jitter, significant children, call cycle, max children; control.t27 effects journal (Closes #7002 #7003 #7004 #7005 #7006) (#7060) * spec(queen): actors restart jitter -- pulled down, phi-hashed, pinned (Refs #7002) backoff_seconds gives every agent of a domain the same wait, so agents that crashed on one provider outage restart in the same second. jittered_seconds pulls the wait down by up to JITTER_PERCENT (20) from a seed the host supplies (the pid's slot): never above the wait, so never above the cap, and still spread at the cap, where a long outage leaves everyone. #7002 asked for "never below wait, never above the cap" -- together those leave zero spread at the cap, so the bound is turned around. Akka's randomFactor and gRPC's +-20% cross their maximum; AWS's equal jitter pulls down by half. The seed goes through Knuth's multiplicative hash with floor(2^32 / phi) = 2654435769 first: a plain `seed % range` puts slots at a stride equal to the range in one second. Test jitter_spreads_one_domain_and_never_crosses_the_cap: bounds for streaks 0..8 x slots 0..63, growth below the cap, 9 distinct seconds for 10 slots at the cap, all 3 seconds for 10 slots at stride 3 at the base wait, two pinned draws (slot 1 = 240, slot 61 = 292). Mutation: - tri mutate spec (lab build of #6993): seed_hash has no guard or operator site; jittered_seconds 1 of 1 killed. The tool does not mutate arithmetic, so that count says little here. - by hand, 12 arithmetic mutants, 12 killed: >> 15, >> 17, no shift, no mod 2^32, * -> + on the multiplier, * -> / on the percent, / 100 -> / 10, % -> / on the draw, percent 25 and 15, multiplier 2654435761 (Knuth's prime: killed only after the slot-61 pin), return wait. - negative controls by hand: plain `seed % (spread + 1)` fails at `seconds == 3`; `wait +` instead of `wait -` fails the bound. 51 pub fns, 23 tests, 0 vacuous; parse, typecheck, gen-rust, gen-verilog, gen-c exit 0; zig test 23/23. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): significant children and auto_shutdown, as OTP 24 (Refs #7003) A supervisor may end itself when its significant children are done: AUTO_ANY_SIGNIFICANT on any one, AUTO_ALL_SIGNIFICANT on the last active one, AUTO_NEVER (0, the default) on none. OTP's restriction is kept: child_spec_valid refuses a significant permanent child and any significant child under AUTO_NEVER. auto_shutdown_after_exit counts only a child that is not restarted (should_restart) and that ended on its own: a child its supervisor stopped never ends the supervisor. The supervisor exits with X_SHUTDOWN (AUTO_SHUTDOWN_REASON). One rule beyond the issue, from OTP's own warning: auto_shutdown_sticks says a supervisor with auto_shutdown must not be a permanent child of its parent, or the shutdown is undone at once. That is the second reason QUEEN_AUTO_SHUTDOWN is AUTO_NEVER: the domain supervisors are permanent children of the root, and a test asserts it. Counts, printed by commands: 54 pub functions (51 before), 11 invariants (9), 24 tests (23); all 24 pass, vacuous passes 0 of 24; parse, typecheck, gen-rust, gen-verilog, gen-c exit 0. tri mutate spec --fn (lab build of #6993 + #7022, --jobs 8): child_spec_valid 8 of 8 killed, auto_shutdown_after_exit 10 of 10, auto_shutdown_sticks 2 of 2. Constants by hand (the tool does not nudge them): 9 mutants, 1 survivor -- AUTO_ALL_SIGNIFICANT 2 -> 3 -- a real gap: the range guard `auto_mode > AUTO_ALL_SIGNIFICANT` then admits the non-mode 2. Killed by the new invariant the_auto_shutdown_modes_are_contiguous (re-run: killed). The new invariant's negative control (AUTO_NEVER == 1) fails zig at comptime. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): a call into its own chain is refused at once, and the chain is bounded (Refs #7004) A runtime runs one turn at a time and a caller blocks, so a call cycle (A calls B, B calls A) left both sides waiting out their timeouts and looking like two hung turns (#6990). Every call now carries its chain: one bit per slot of the callers blocked on it (this caller included) and their count. call_admit refuses a callee already on the chain with CALL_CYCLE before any send, alias or monitor, and a depth past CALL_MAX_DEPTH (8) with CALL_TOO_DEEP. A cycle is named before the depth. Prior art, read for this commit: Erlang's gen_server:call refuses only a call to self (calling_self) and leaves longer cycles to the 5000 ms timeout; Orleans deadlocks a non-reentrant cycle until the call times out; Dapr refuses a call back into the chain unless reentrancy is on and bounds a reentrant chain at maxStackDepth 32. Choices beyond the issue, stated in the spec: - The slot, not the pid, is on the chain: a runtime blocked on a chain is alive, so its slot is not reused while the chain lasts. A caller that dies and whose slot is reused makes a call to the new owner read as a cycle; that chain's reply goes to a dead alias, so nothing is lost. - The model tracks slots 0..63 (CHAIN_SLOTS, one u64). A slot past it is never on the chain: a call to it is admitted unchecked, and a cycle through it waits out the timeout, as in Erlang. An invariant checks the Queen's 23 processes (control.t27's 4 domains of 4 agents, as literals per the owner rule) fit, given a runtime that hands out the lowest free slot. - CALL_MAX_DEPTH 8 is chosen, not measured; Dapr's 32 is for a reentrant chain. - A send carries no chain: it waits for nothing, so it closes no cycle. Counts, printed by commands: 57 pub functions (54 before), 13 invariants (11), 25 tests (24); all 25 pass, vacuous passes 0 of 25; parse, typecheck, gen-rust, gen-verilog, gen-c exit 0. tri mutate spec --fn (lab build of #6993 + #7022, --jobs 8): chain_has 6 of 6 killed, chain_add 5 of 5, call_admit 4 of 4. By hand: 13 mutants (the 4 new constants up and down, << to >>, | to ^ and &, > to >=, the two guards swapped), 13 killed. The two new invariants' negative controls (CALL_TOO_DEEP == 6; a depth bound past the model; a population of 4 x 16 agents) each fail zig at comptime. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(now): actors jitter, significant children, call cycle -- whole-file mutation count (Refs #6971) The three follow-ups (#7002, #7003, #7004) in one NOW entry, with the whole-file tri mutate spec run on this branch: 296 mutants, 290 killed, the 6 known equivalents survive, 0 of the 35 new. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): a full domain refuses a new start and still restarts its own (Refs #7005) start_answer(live, stopping, max_children) refuses a start past the bound with START_MAX_CHILDREN, inside the supervisor's own turn, so two starts decided on one stale count (control.t27 placement) cannot both pass. A child being stopped counts until its EXIT. children_after_exit keeps a restarted child's place, so a restart never asks the bound. The issue asked for a per-domain MAX_CHILDREN constant. It is not added: control.t27 already owns DOMAIN_CAP and placement's P_WAIT, so a second constant would be a second home for one number. The bound is a parameter the Queen fills from DOMAIN_CAP; a refused start leaves control.t27's P_WAIT (the task stays unleased), never a drop. Prior art: Elixir DynamicSupervisor checks max_children in handle_call, does not check it on restart, and deletes a terminated child only after its exit; a Temporal worker with no free slot stops polling. Mutants: tool 8 of 8 killed (start_answer 4, children_after_exit 4); hand 8 of 8 killed. Without the new invariant, START_OK 0 -> 1 and START_MAX_CHILDREN 1 -> 0 both survive, so the invariant is what pins them. 59 pub fn, 14 invariants, 26 tests, 26 passed, 0 vacuous. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(now): actors max children -- counts and whole-file run after #7005 (Refs #7005) 59 pub fn, 14 invariants, 26 tests; whole file 304 mutants, 298 killed, the same 6 equivalents. The "35 mutants added since" line is replaced by a claim the survivor lines check: none sits on a line #7002-#7005 added. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): an effects journal so a new lease holder does not repeat what the old one did (Refs #7006) A fence stops the old holder's writes, not what it already did outside: a crash after a push but before the next journal write left the new holder to push again, open a second pull request or post a second comment. control.t27 section 7 adds the journal's contract: - an entry per effect, intent written before it and done after it, at the holder's fence; the key is (task, kind, target), not the position (a model turn is not deterministic, so Temporal/Restate's replay by position does not apply) and not the fence (every retry must see the same key, as Temporal's run id + activity id leaves the attempt out); - effect_action: a stale fence does nothing; no entry runs; done skips; an open intent looks the effect up at GitHub where it can (push, pull request, comment) and runs again where it cannot (a model call repeats once per crash that leaves its intent open); - look_wait_seconds: after a DOWN, a look waits out GitHub's 10 s request limit, so a request the old holder sent cannot land after the look; an invariant keeps that wait under the first heartbeat; - effect_may_repeat: a push (leased) and a pull request (one per head, 422) are refused by the receiver; a comment can still repeat behind a partition, and the journal's marker only makes the copy detectable. actors.t27 reclaim_wait_seconds points at the journal (doc only; the spec does not import control.t27, T7). Counts printed by commands: control.t27 42 pub fn, 8 invariants, 15 tests, 15/15 zig, 0 vacuous; actors.t27 59/14/26 unchanged, 26/26. tri mutate spec --fn on the 7 new functions (lab, #7043 build): 36 of 36 killed after one gap: dropping `seconds_since_down > LIMIT` survived (at 11 s both paths return 0); asserts at 12 s and 3600 s now kill it (the u32 subtraction underflows). Hand constant mutants 16/16 killed; without the_effect_codes_are_distinct the four DO_* mutants survive, so that invariant is what pins the action codes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(now): control.t27 effects journal -- design, counts and mutation run (Refs #7006) The entry now closes #7006 too: the journal key, effect_action, look_wait_seconds and effect_may_repeat, the answer to the issue's Restate question, and the counts and mutation results printed by commands in the same tick (control.t27 42/8/15, 36 of 36 tool mutants after one gap, 16 hand constant mutants). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): name the assumption under the journal's look wait (Refs #7006) GitHub documents that it terminates a request after 10 s; it does not document that a write it terminated is never applied later. The look wait rests on that assumption, so the doc now says so, and says what fails if it is wrong: a comment can repeat even after a DOWN, and its marker shows the copy. Doc only; 15/15 tests unchanged.

Closes #6108 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(codegen): gen-rust enum order and gen-zig float-call cast (Closes #6941) gen-rust recorded an enum's name only when it emitted the enum. `use` splices an imported enum after the functions, so every function lowered `Trit.pos` as a field access (E0423) and a switch arm `.neg` as a binding that matches every value (E0170). The names are now collected before the first function is emitted. gen-zig's is_float_expr had no arm for calls, so `(half() - quarter()) as f32` and `half() as f32` were lowered to `@floatFromInt`, which Zig refuses on an f64. A call to a function the spec declares with a float return type is now a float expression. Regression specs: specs/compiler/rust_enum_order.t27 and specs/compiler/zig_float_call_cast.t27.

Both sides disagreed with specs/numeric/gf16.t27 (L6): - spec: gf16_to_f32, ternary_to_f32 and quantize_value returned gf16 (lowered to u16); the SSOT decoder gf16_decode_to_f32 returns f32.

They now have bodies built from the numeric SSOT (GF16 [S|E6|M9], bias 31, specs/numeric/gf16.t27 and FORMAT-SPEC-001.json): - gf16_to_f32 decodes zero, denormals, normals, +/-Inf and NaN exactly. - f32_to_gf16 rounds to nearest with ties away from zero, as gf16_encode_f32 does; overflow goes to +/-Inf, NaN to 0x7F01. - f32_to_ternary / ternary_to_f32 / format_bytes / quantize_value. Eight new tests, including an exhaustive decode-then-encode round trip over all 65536 codes. Trit members are spelled Trit::pos because gen-rust only learns an enum's name when it emits the enum, and a `use`-imported enum is emitted after the functions. ring-096 encoded every denormal at twice its value and 2^-31 as +0: its scale-down loop ran to e = 0 instead of stopping at e = 1.

Zig parses an untyped float literal to the nearest binary128, rounds each compile-time + - * / to binary128, compares binary128 values and rounds once to f64 or f32 where a typed float is needed. t27b held the nearest f64 plus an exact flag and refused every inexact fold. Val::Cf now holds float::Q, computed exactly with integers and rounded to nearest even: literals, the four operations, comparison, one rounding to f64 (refused past its range) and to f32 (infinity past its range, as before), and @intFromFloat of a value that is exactly an f64.

Akka's randomFactor and gRPC's +-20% cross their maximum; AWS's equal jitter pulls down by half. The seed goes through Knuth's multiplicative hash with floor(2^32 / phi) = 2654435769 first: a plain `seed % range` puts slots at a stride equal to the range in one second. Test jitter_spreads_one_domain_and_never_crosses_the_cap: bounds for streaks 0..8 x slots 0..63, growth below the cap, 9 distinct seconds for 10 slots at the cap, all 3 seconds for 10 slots at stride 3 at the base wait, two pinned draws (slot 1 = 240, slot 61 = 292). Mutation: - tri mutate spec (lab build of #6993): seed_hash has no guard or operator site; jittered_seconds 1 of 1 killed. The tool does not mutate arithmetic, so that count says little here. - by hand, 12 arithmetic mutants, 12 killed: >> 15, >> 17, no shift, no mod 2^32, * -> + on the multiplier, * -> / on the percent, / 100 -> / 10, % -> / on the draw, percent 25 and 15, multiplier 2654435761 (Knuth's prime: killed only after the slot-61 pin), return wait. - negative controls by hand: plain `seed % (spread + 1)` fails at `seconds == 3`; `wait +` instead of `wait -` fails the bound. 51 pub fns, 23 tests, 0 vacuous; parse, typecheck, gen-rust, gen-verilog, gen-c exit 0; zig test 23/23. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): significant children and auto_shutdown, as OTP 24 (Refs #7003) A supervisor may end itself when its significant children are done: AUTO_ANY_SIGNIFICANT on any one, AUTO_ALL_SIGNIFICANT on the last active one, AUTO_NEVER (0, the default) on none. OTP's restriction is kept: child_spec_valid refuses a significant permanent child and any significant child under AUTO_NEVER. auto_shutdown_after_exit counts only a child that is not restarted (should_restart) and that ended on its own: a child its supervisor stopped never ends the supervisor. The supervisor exits with X_SHUTDOWN (AUTO_SHUTDOWN_REASON). One rule beyond the issue, from OTP's own warning: auto_shutdown_sticks says a supervisor with auto_shutdown must not be a permanent child of its parent, or the shutdown is undone at once. That is the second reason QUEEN_AUTO_SHUTDOWN is AUTO_NEVER: the domain supervisors are permanent children of the root, and a test asserts it. Counts, printed by commands: 54 pub functions (51 before), 11 invariants (9), 24 tests (23); all 24 pass, vacuous passes 0 of 24; parse, typecheck, gen-rust, gen-verilog, gen-c exit 0. tri mutate spec --fn (lab build of #6993 + #7022, --jobs 8): child_spec_valid 8 of 8 killed, auto_shutdown_after_exit 10 of 10, auto_shutdown_sticks 2 of 2. Constants by hand (the tool does not nudge them): 9 mutants, 1 survivor -- AUTO_ALL_SIGNIFICANT 2 -> 3 -- a real gap: the range guard `auto_mode > AUTO_ALL_SIGNIFICANT` then admits the non-mode 2. Killed by the new invariant the_auto_shutdown_modes_are_contiguous (re-run: killed). The new invariant's negative control (AUTO_NEVER == 1) fails zig at comptime. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): a call into its own chain is refused at once, and the chain is bounded (Refs #7004) A runtime runs one turn at a time and a caller blocks, so a call cycle (A calls B, B calls A) left both sides waiting out their timeouts and looking like two hung turns (#6990). Every call now carries its chain: one bit per slot of the callers blocked on it (this caller included) and their count. call_admit refuses a callee already on the chain with CALL_CYCLE before any send, alias or monitor, and a depth past CALL_MAX_DEPTH (8) with CALL_TOO_DEEP. A cycle is named before the depth. Prior art, read for this commit: Erlang's gen_server:call refuses only a call to self (calling_self) and leaves longer cycles to the 5000 ms timeout; Orleans deadlocks a non-reentrant cycle until the call times out; Dapr refuses a call back into the chain unless reentrancy is on and bounds a reentrant chain at maxStackDepth 32. Choices beyond the issue, stated in the spec: - The slot, not the pid, is on the chain: a runtime blocked on a chain is alive, so its slot is not reused while the chain lasts. A caller that dies and whose slot is reused makes a call to the new owner read as a cycle; that chain's reply goes to a dead alias, so nothing is lost. - The model tracks slots 0..63 (CHAIN_SLOTS, one u64). A slot past it is never on the chain: a call to it is admitted unchecked, and a cycle through it waits out the timeout, as in Erlang. An invariant checks the Queen's 23 processes (control.t27's 4 domains of 4 agents, as literals per the owner rule) fit, given a runtime that hands out the lowest free slot. - CALL_MAX_DEPTH 8 is chosen, not measured; Dapr's 32 is for a reentrant chain. - A send carries no chain: it waits for nothing, so it closes no cycle. Counts, printed by commands: 57 pub functions (54 before), 13 invariants (11), 25 tests (24); all 25 pass, vacuous passes 0 of 25; parse, typecheck, gen-rust, gen-verilog, gen-c exit 0. tri mutate spec --fn (lab build of #6993 + #7022, --jobs 8): chain_has 6 of 6 killed, chain_add 5 of 5, call_admit 4 of 4. By hand: 13 mutants (the 4 new constants up and down, << to >>, | to ^ and &, > to >=, the two guards swapped), 13 killed. The two new invariants' negative controls (CALL_TOO_DEEP == 6; a depth bound past the model; a population of 4 x 16 agents) each fail zig at comptime. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(now): actors jitter, significant children, call cycle -- whole-file mutation count (Refs #6971) The three follow-ups (#7002, #7003, #7004) in one NOW entry, with the whole-file tri mutate spec run on this branch: 296 mutants, 290 killed, the 6 known equivalents survive, 0 of the 35 new. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): a full domain refuses a new start and still restarts its own (Refs #7005) start_answer(live, stopping, max_children) refuses a start past the bound with START_MAX_CHILDREN, inside the supervisor's own turn, so two starts decided on one stale count (control.t27 placement) cannot both pass. A child being stopped counts until its EXIT. children_after_exit keeps a restarted child's place, so a restart never asks the bound. The issue asked for a per-domain MAX_CHILDREN constant. It is not added: control.t27 already owns DOMAIN_CAP and placement's P_WAIT, so a second constant would be a second home for one number. The bound is a parameter the Queen fills from DOMAIN_CAP; a refused start leaves control.t27's P_WAIT (the task stays unleased), never a drop. Prior art: Elixir DynamicSupervisor checks max_children in handle_call, does not check it on restart, and deletes a terminated child only after its exit; a Temporal worker with no free slot stops polling. Mutants: tool 8 of 8 killed (start_answer 4, children_after_exit 4); hand 8 of 8 killed. Without the new invariant, START_OK 0 -> 1 and START_MAX_CHILDREN 1 -> 0 both survive, so the invariant is what pins them. 59 pub fn, 14 invariants, 26 tests, 26 passed, 0 vacuous. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(now): actors max children -- counts and whole-file run after #7005 (Refs #7005) 59 pub fn, 14 invariants, 26 tests; whole file 304 mutants, 298 killed, the same 6 equivalents. The "35 mutants added since" line is replaced by a claim the survivor lines check: none sits on a line #7002-#7005 added. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): an effects journal so a new lease holder does not repeat what the old one did (Refs #7006) A fence stops the old holder's writes, not what it already did outside: a crash after a push but before the next journal write left the new holder to push again, open a second pull request or post a second comment. control.t27 section 7 adds the journal's contract: - an entry per effect, intent written before it and done after it, at the holder's fence; the key is (task, kind, target), not the position (a model turn is not deterministic, so Temporal/Restate's replay by position does not apply) and not the fence (every retry must see the same key, as Temporal's run id + activity id leaves the attempt out); - effect_action: a stale fence does nothing; no entry runs; done skips; an open intent looks the effect up at GitHub where it can (push, pull request, comment) and runs again where it cannot (a model call repeats once per crash that leaves its intent open); - look_wait_seconds: after a DOWN, a look waits out GitHub's 10 s request limit, so a request the old holder sent cannot land after the look; an invariant keeps that wait under the first heartbeat; - effect_may_repeat: a push (leased) and a pull request (one per head, 422) are refused by the receiver; a comment can still repeat behind a partition, and the journal's marker only makes the copy detectable. actors.t27 reclaim_wait_seconds points at the journal (doc only; the spec does not import control.t27, T7). Counts printed by commands: control.t27 42 pub fn, 8 invariants, 15 tests, 15/15 zig, 0 vacuous; actors.t27 59/14/26 unchanged, 26/26. tri mutate spec --fn on the 7 new functions (lab, #7043 build): 36 of 36 killed after one gap: dropping `seconds_since_down > LIMIT` survived (at 11 s both paths return 0); asserts at 12 s and 3600 s now kill it (the u32 subtraction underflows). Hand constant mutants 16/16 killed; without the_effect_codes_are_distinct the four DO_* mutants survive, so that invariant is what pins the action codes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(now): control.t27 effects journal -- design, counts and mutation run (Refs #7006) The entry now closes #7006 too: the journal key, effect_action, look_wait_seconds and effect_may_repeat, the answer to the issue's Restate question, and the counts and mutation results printed by commands in the same tick (control.t27 42/8/15, 36 of 36 tool mutants after one gap, 16 hand constant mutants). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * spec(queen): name the assumption under the journal's look wait (Refs #7006) GitHub documents that it terminates a request after 10 s; it does not document that a write it terminated is never applied later. The look wait rests on that assumption, so the doc now says so, and says what fails if it is wrong: a comment can repeat even after a DOWN, and its marker shows the copy. Doc only; 15/15 tests unchanged.

This closes them in the spec: - #6972 control lane: cancel and heartbeat survive a full mailbox, coalesce per kind, and are taken before data; - #6974 call: reply, DOWN or timeout; a reply wins over a DOWN; the alias dies with the call, so a late reply reaches nobody; - #6975 backoff: a slow crash loop extends an unstable streak, waits 10 s doubling to 300 s, and gives up to the parent past 6; - #6990 hung turn: past TURN_MAX_SECONDS the supervisor kills the turn and the DOWN reclaims its task at once; - #6991 dead letters: every lost message is counted, a coalesced one is not; - #6992 two Erlang corners stated (no trappable kill on a link; no exit(self, normal) quirk); - #6976 coverage: all 49 pub functions called by a test, section 7 pinned by an invariant with a negative control. 22 tests and 9 invariants pass, 0 vacuous; gen-rust, gen-c, gen-verilog exit 0; 40 of 41 new-line mutants killed, the survivor is equivalent.

Two were test gaps and are closed here: - pid_of: `slot > GEN_MASK` -> `>=` survived; slot GEN_MASK is a real slot, now asserted. - mbox_push: `tag > TAG_MASK` -> `>=` survived; tag 255 is a message, now asserted. Both mutants were applied by hand and now fail `zig test`. Six are equivalent and stay: - mbox_len and mbox_find loop bounds `< MBOX_SLOTS` -> `<=`: mbox_tag returns 0 past the last slot, so both loops end the same way. - ctl_next `t < CTL_TAGS` -> `<=`: ctl_pending is false for tag 64. - backoff_seconds `wait >= CAP` -> `>`: 10 * 2^k never equals 300. - backoff_seconds…

Why
formats_catalog.t27lists mxfp8, mxfp6 and mxfp4 and cites OCP MX v1.0, ande8m0.t27specifies the shared scale byte, but no spec decoded one MX or OFP8 element code or ran the section 6.3 conversion. That conversion is where MX's known weakness lives: one outlier sets the scale for all 32 values, and the small ones fall to zero. This spec measures it.What (one file,
.t27only)specs/numeric/ocp_mx.t27, moduleOCP_MX:units: count magnitudes in units of the smallest subnormal, soe == 0 -> mande > 0 -> (2^M + m) * 2^(e-1).floor(log2 max|V|) - emax_elem(section 6.3, Table 7). Inputs are in 2^-12 and outputs in 2^-24, so every assert is exact.fractions) implementation of section 6.3 and are checked bit for bit for MXFP4, MXFP6 (E2M3, E3M2), MXFP8 E4M3 and MXINT8.Measured on that block:
On this block E3M2 beats E2M3: range wins over precision at six bits, because the outlier pushes the small weights into E2M3's subnormals.
Sources
Not covered: OFP8's non-saturating overflow mode, and the all-zero block, which section 6.3 leaves undefined.

/. Every runtime index now goes through@intCast, the ratio asserts multiply instead of divide, and the storage-cost numerator is a named constant. "Generates" and "compiles" are different claims; this PR now makes both.Next
The spec feeds a course continuation on AI number formats and site widgets: plays that run these same tests in the browser. These land in gHashTag/trinity after this merges.
