+# HexIntFactor performance
+
+## Scope and acceptance
+
+This is the Phase-4 report for `HexIntFactor`. It covers the five input
+families declared in `libraries.yml`: table and balanced semiprimes, smooth and
+unbalanced semiprimes, power forms, certificate replay and order, and
+generalized divisor sums. The exact declared comparator name is
+**PARI factor and GMP-ECM**. Both endpoints are informational: PARI exposes a broader
+factorization portfolio, while GMP-ECM is a separately tuned C implementation.
+
+The compiled scientific track contains seven parametric and 31 fixed targets.
+Every parametric target returned the exact harness verdict
+`consistent_with_declared_complexity`; every fixed target completed its
+preregistered repeats, agreed across hashes, matched its canonical expected
+hash, and passed its collector-owned scientific budget. The benchmark bodies
+contain only generous process timeouts, so `verify` remains a correctness and
+bitrot check rather than a shared-runner timing gate.
+
+The `HexIntFactorMathlib` audit under #9368 classifies the bridge as a
+correspondence-only layer. `HexIntFactor` therefore remains the computational
+performance owner.
+
+## Bench targets
+
+| Declared family | Compiled and kernel targets | Role |

+
+## Factorization decomposition and retained power route
+
+The balanced five-seed family is deliberately three different surfaces. Full
+public `factor?` includes preprocessing, primality rejection, splitting,
+recursive completion, certificate construction, and checked acceptance. Raw
+rho starts from the declared seed and returns only a normalized split. The
+public route advances its generator during primality work before reaching rho,
+so raw rho and full public factorization are separate deterministic executions,
+not a continuous timing decomposition. Completion starts from the exact split
+and advanced generator state produced by the direct-rho execution, factors both
+sides, canonically merges them, and runs checked acceptance. The untimed control
+recomputes that direct-rho trajectory and proves that the stored split/state and
+both complete outputs agree.
+
+| bits | public route | public full | raw rho split | post-split completion | full / rho | full / (rho + completion) |
+|---:|---|---:|---:|---:|---:|---:|
+| 32 | table-complete | 0.561 ms | 0.111 ms | 1.236 ms | 5.035x | 0.417x |
+| 40 | rho-driven | 6.556 ms | 2.322 ms | 3.902 ms | 2.823x | 1.053x |
+| 48 | rho-driven | 13.399 ms | 9.144 ms | 3.778 ms | 1.465x | 1.037x |
+| 56 | rho-driven | 43.405 ms | 38.593 ms | 3.869 ms | 1.125x | 1.022x |
+| 64 | rho-driven | 193.957 ms | 182.306 ms | 4.460 ms | 1.064x | 1.039x |
+| 72 | rho-driven | 716.677 ms | 726.745 ms | 4.577 ms | 0.986x | 0.980x |
+| 80 | rho-driven | 3127.039 ms | 3200.147 ms | 4.764 ms | 0.977x | 0.976x |
+
+The two ratios are explanatory observations, not gates between unequal APIs.
+The 32-bit public operand is fully consumed by the committed prime table, so
+its raw-rho and completion columns are cross-surface diagnostics rather than a
+decomposition of the public route. On the 40--80-bit rho-driven rungs, the
+ratios show fixed completion cost dominating the low rungs and raw rho
+dominating the upper rungs. Ratios below one are possible because the public
+and direct-rho generator trajectories differ. They do not define a second
+algorithm or support an inference about SQUFOF.
+
+The independent table control has identical canonical hashes: public dispatch
+is 0.037249 ms and direct trial division is 0.031543 ms, a 1.181x ratio under
+the preregistered 1.25 gate.
+
+Generic and cyclotomic power factorization use the same target-derived seed,
+the same exponent set 12 through 80 (including 72 and 80), and canonical
+complete-factorization encodings. Both have hash `0x681a285cd74ea124` over
+seven repeats. The split/generic median ratio is 0.946, satisfying the
+preregistered `<= 0.98` retention rule by 3.4 percentage points, so the
+specialized route remains. That margin is real but intentionally modest; the
+seven retained paired repeats make it visible rather than hiding it in one run.
+
+Every one of the 49 default-fuel cases succeeded, including all direct-`Nat`
+balanced, smooth, ECM, and power cases through 80 bits. The maximum observed
+charge is 34 attempts; the maximum committed fuel is 352.
+
+## Mode-3 conversion and absolute budgets
+
+For the fixed families, asymptotic regression detection was explicitly given
+up rather than retrofitting a slope:
+
+- Full balanced factorization was attempted as a five-seed 32--80-bit
+  `2^(bits/4)` schedule. Certificate construction and completion dominate
+  different lower rungs, so only the isolated raw-rho surface retains that
+  model.
+- Integer value is not a useful table parameter because it mixes unrelated
+  factor shapes; the committed uniform batch is the workload.
+- Fixed-bound p-1 crosses word/direct-`Nat` regimes and plateaus in limb count.
+  No single observed parameter gave a stable tight model.
+- ECM has only three word and three direct-`Nat` rungs. That sparse schedule
+  cannot distinguish constant, linear, and multiplication costs.
+- Cyclotomic and power-form cost changes with divisor and factor shape, not
+  monotonically with exponent alone.
+- The downstream order and primitive-root probes are fixed because the chosen
+  50- and 61-bit primes have deliberately short orders; treating operand width
+  as a general order-cost model would be false.
+
+Budgets were preregistered from the preceding clean pinned-host diagnostic,
+rounded upward to coarse 10/20/50/100/200/500/750/2000/6000 ms ceilings. A
+10 ms resolution envelope is the minimum for sub-millisecond targets. The
+slowest target still has 91.9% clean-baseline headroom; all other targets have
+at least 109.9%. `margin` is `(budget / clean median - 1) * 100`.

+
+## External comparator ratios
+
+PARI 2.17.3 times a calibrated in-process `factor` batch. The Hex side is
+normalized from each five-seed batch to one factorization before the ratio is
+formed. PARI does not expose the same route portfolio, so these values are
+context rather than an internal rho or dispatch gate.
+
+| bits | Hex factor per call | PARI `factor` | Hex / PARI |
+|---:|---:|---:|---:|
+| 32 | 0.112 ms | 0.003 ms | 32.84x |
+| 40 | 1.311 ms | 0.006 ms | 223.76x |
+| 48 | 2.680 ms | 0.062 ms | 43.56x |
+| 56 | 8.681 ms | 0.135 ms | 64.42x |
+| 64 | 38.791 ms | 0.119 ms | 325.59x |
+| 72 | 143.335 ms | 0.184 ms | 780.72x |
+| 80 | 625.408 ms | 0.422 ms | 1482.45x |
+
+The low rungs are irregular because the implementations select different
+portfolios. From 48 through 80 bits the ratio grows sharply from 43.56x to
+1482.45x. The accompanying raw-rho profile attributes the Hex-side cost to the
+Brent loop, allocation, and GMP, while the wall ratio also includes an expected
+portfolio and algorithm-class divergence from PARI. It is useful orientation,
+not a standalone unresolved defect and not evidence for a particular
+unobserved PARI route.
+
+GMP-ECM 7.0.6 uses exactly `ecm -q -sigma 0:7 1000 1`: parameterization 0,
+curve sigma 7, B1 1000, and B2 below B1 to disable stage 2. The explicit
+`parameterization:sigma` syntax removes any dependence on GMP-ECM's default;
+verbose probes report `sigma=0:7` for every operand. Every operand and the
+overhead control use the same persistent 256-input batch. The measured floor
+is 0.219 ms/input; a row is ratio-eligible only under the preregistered rule
+that this floor is at most 50% of raw time. Equal discovered factors do not
+imply equal stage-1 wall cost: a curve can reach a gcd checkpoint with the
+whole composite on one cofactor while yielding a nontrivial gcd on another.
+Output reconstruction is checked even for ineligible rows.
+
+| bits | Hex ECM | GMP raw | adjusted | factor found | eligible | Hex / adjusted |
+|---:|---:|---:|---:|:---:|:---:|---:|
+| 48 | 0.060 ms | 0.479 ms | 0.260 ms | yes | yes | 0.23x |
+| 56 | 0.060 ms | 0.258 ms | 0.040 ms | yes | no | -- |

+| 80 | 4.270 ms | 0.374 ms | 0.155 ms | yes | no | -- |
+
+Only the 48-bit row supports a ratio conclusion. No ratio is inferred from the
+five overhead-dominated rows.

+`bb36b862702dfba3cd370f82acd4bb9cdf1d020b1668a1163079f8f35230c547`).
+It records clean source commit `7d0ee1e2a479d08a9eeaf617531a3b113aa43e55`,

+expected axiom inventory `[propext]`. `release_quality` is true: there are no
+violations, preflight failures, or exhausted pairs. Contaminated pair attempts
+were discarded and retried.
+
+Each candidate is a fresh module containing an actual `decide +kernel`
+`checkFactorization` replay; its paired reference imports the same support but
+does not replay the certificate. The last case includes a 61-bit factor.
+
+The two preregistered null controls expose fresh-build noise before the

+The candidate medians are flat across `k = 1..10`; the 61-bit final witness
+does not introduce a visible replay cliff at this resolution. Individual raw
+samples contain large positive excursions mirrored by the null controls, so
+the claim is deliberately limited to the rotated-pair medians and 5000 ms
+budget rather than a fine-grained slope.

+
+The balanced rho profile attributes its dominant cost to allocation and GMP
+underneath the Brent loop. The smooth/unbalanced profile directly exercises
+ECM stage 1 rather than duplicating rho. Power forms are dominated by trial
+division and exact-power removal, order by the repository's private compiled
+order scan, and the large-exponent sigma case by GMP arithmetic. No declared
+family is left with an unattributed dominant cost.
+
+The five analytical summaries are committed as
+`reports/bench-results/hex-int-factor-profile-{balanced,ecm,order,power,sigma}-60230acab-chungus2.json`.
+They retain the complete leaf-category tables, inclusive rankings, calibration
+diagnostics, sensitivity checks, and raw-profile paths; the SHA-256 values in
+the table identify the uncommitted compressed captures themselves.

+The artifact preserves the full benchmark export, controls, all 49 fuel rows,
+seven comparator rounds, external outputs, exact versions and commands, host
+state, and source/executable hashes. Raw profiles and their symbol sidecars
+remain under `/tmp`; their content hashes above make each cited capture
+identifiable. The profiling orchestrator has SHA-256
+`ef0aabd98ef0dee35feb19696e006ef64849cba6140b433024d950c6c7c5e32e`;
+the summarizer has SHA-256

+`f5b5ebb676b6a59188cd59145c5bec78041ceba5845a4b8b819888a552b59069`.
+
+## Concerns
+
+GMP-ECM's specialized stage-1 implementation is externally faster on its one
+eligible row, and PARI's broader factorization portfolio is faster on every
+balanced rung. These are expected algorithm- and implementation-class gaps
+recorded for orientation, not missing attribution or a failed gating
+requirement.
