Make the AMM simulator wheels reproducible, so a wheel's sha256 can be checked against independent builds wherever it is hosted. Goal 00b9cdc8 built wheels of amm_sim_rs from github.com/benedictbrady/amm-challenge at 6b6921f8d463314aa7c96234e1be25a25245f704 on four machines: all passed the gates, but no two were byte-identical (wheel B 727916 to 727933 bytes). Likely causes: build paths embedded in the binary, the wheel's zip timestamps, and no committed Cargo.lock. This goal pins those and measures whether builds match, within one machine across two checkout paths and across machines. Nothing is submitted anywhere; never download any wheel.

Toolchain, all under the workspace's .cache/ folder (TMPDIR, RUSTUP_HOME, CARGO_HOME, UV_CACHE_DIR, UV_PYTHON_INSTALL_DIR, SOLCX_BINARY_PATH, ZIG_GLOBAL_CACHE_DIR in .cache/tc): uv from https://github.com/astral-sh/uv/releases/latest/download/uv-x86_64-unknown-linux-gnu.tar.gz (another platform: its own uv archive), tar --no-same-owner; uv venv --python 3.12; uv pip install maturin==1.16.0 ziglang==0.17.1 numpy py-solc-x==2.1.0 pyrevm==0.3.7. Rust: the rustup script with -y --profile minimal --no-modify-path --default-toolchain none, then rustup toolchain install 1.99.1 --profile minimal, RUSTUP_TOOLCHAIN=1.99.1, rustup target add x86_64-unknown-linux-gnu.

Every build: SOURCE_DATE_EPOCH = the commit's time (git log -1 --format=%ct), CARGO_INCREMENTAL=0, RUSTFLAGS="--remap-path-prefix==/src --remap-path-prefix=<CARGO_HOME>=/cargo --remap-path-prefix=<RUSTUP_HOME>=/rustup" with absolute paths, and maturin build --release --strip --locked --zig --target x86_64-unknown-linux-gnu --compatibility manylinux2014 --features pyo3/abi3-py310 --manifest-path amm_sim_rs/Cargo.toml --out . The commit has no Cargo.lock: generate one with cargo generate-lockfile --manifest-path amm_sim_rs/Cargo.toml and use that same file in every checkout. Wheel A = the commit unchanged. Wheel B = plus scratch/instrumentation.patch from the source_files of https://api.imd.fun/artifacts/02c134d9ed51858f06d02b6dec25e6922016490f11e3a8174af512a6a77b6569 (git apply) and version = "0.1.0.post1" in amm_sim_rs/pyproject.toml.

For comparison only: Taylor's reference release lists A 11fcc2748d430bc73c5acb107ca1fab9a6719b86bc2b0960c9cbcc374b6eba4e and B 6c6a439e3aff01fe014123559ec5c1b6414b515a74cbe0402a31ded19716bfce.

The answer

amm_sim_rs wheel reproducibility — pinned-build results

Bottom line: the wheels are still not reproducible. Across all 6 machine-results (items r1–r6, each building wheel A unchanged and wheel B with scratch/instrumentation.patch + version = "0.1.0.post1", each in two checkout paths p1 and pathtwo/x), no two of the 12 wheel-A builds share a sha256, and no two of the 12 wheel-B builds share a sha256. That is an improvement in degree but not in kind over goal 00b9cdc8 (B was 727916–727933 bytes there; here B is 727735–727756 bytes, a tighter spread from pinning SOURCE_DATE_EPOCH, committing one Cargo.lock, and --remap-path-prefix), but byte-identical reproduction across machines/paths still fails.

The good news: every result that reports it shows the compiled extension itself (amm_sim_rs.abi3.so) is byte-identical, both between the two checkout paths on one machine and (where comparable) across machines. The one remaining, fully identified cause of wheel-sha256 mismatch in every single result is maturin 1.16.0's CycloneDX SBOM (dist-info/sboms/amm_sim_rs.cyclonedx.json), which embeds the absolute checkout path in 3 bom-ref/ref fields (path+file://<checkout>/amm_sim_rs#0.1.0); --remap-path-prefix does not reach it, so it differs whenever the checkout's absolute path differs — which it does both between p1/pathtwo/x on one machine and between any two machines' own absolute workspace paths. RECORD then differs too (it records the SBOM's own hash/size). __init__.py, METADATA, WHEEL, and the .so are identical in every reported diff; all zip timestamps equal SOURCE_DATE_EPOCH (2026-02-07 23:12:24) everywhere.

Per-result table

All 6 results built commit 6b6921f8d463314aa7c96234e1be25a25245f704 with SOURCE_DATE_EPOCH=1770505944, rustc/cargo 1.99.1, maturin 1.16.0, zig 0.17.1, the brief's exact maturin build flags and --remap-path-prefix for checkout/CARGO_HOME/RUSTUP_HOME.

"Paths agree" is "no" for every result: within a machine, p1's wheel sha256 never equals pathtwo/x's wheel sha256, for either A or B. Across all 24 wheel-A/B sha256 values in the table, every single one is distinct — no two results, and no two paths, produced the same wheel.

What two or more machines DID produce identically

  • Cargo.lock: r1, r2, r3, r4 and r6 all generated the exact same Cargo.lock sha256 b5efc7f1aaf2c92fafa2015404ff74f760b80135a9e16bacded7f4ba0c81690b (75461 bytes) via cargo generate-lockfile --manifest-path amm_sim_rs/Cargo.toml on cargo 1.99.1 — 5 of 6 results agree exactly on lockfile content. r1's notes say "311 packages" while r3/r4 give the field "packages": 312; since the sha256 is identical across all five, this is a labeling inconsistency in the notes, not a content difference. r5 alone generated a different Cargo.lock, sha256 a180854ccb8f32e0104bafea81d25b08a916116c80b9d44a2e3d17dfeed3cc65, same byte count (75461) but different content — i.e. cargo generate-lockfile is itself not deterministic run-to-run (crates.io index state can differ), which is exactly why the brief requires committing one shared Cargo.lock rather than regenerating it per machine.
  • The compiled .so (amm_sim_rs/amm_sim_rs.abi3.so, the actual Rust extension): r1, r3, r4 and r5 each give an explicit so_sha256, and all four report the same pair of hashes for every one of their builds (both checkout paths, both wheel A and wheel B):
    • A: 414ea6d201d299b2967b2aee72c9704758fa69acf6df6cd295d83598118efd37
    • B: ff88b6353c2aad7342f0a26194f7347e78b9c3b38d683a7449006d423978cd14 Notably r5 reached this same .so despite having a different Cargo.lock than r1/r3/r4 — so the lockfile difference there did not change the compiled bytes. r2 and r6 also report (in prose notes, without publishing the hash) that their own two paths' .so files are byte-identical to each other; their matching the 414ea6d2…/ff88b635… above could not be confirmed from what they reported, so that is left unconfirmed rather than assumed.
  • The gate: every one of the 6 results passes both checks identically: CH.sol (sha256 6dd68f77a70900319460215374143dbd5d924198450a46d9f5f91f6b1e3d35c3) vs VanillaStrategy over seeds 0..999 gives mean 525.5258821780834 for both A and B, matching the expected value in every result (r3 gives the fuller decimal 525.52588217808343827 for both). V2.sol (sha256 28417e116f57f1029fdd1803832e852574902c1ae7253c05657f317db76da4ab) run twice with wheel B gives, in every result: afterSwap calls 21580, ok 21577, oog 3, max_ok_gas 243554; afterInitialize max_ok_gas 236377; harness exit code 2 / valid=false, expected because of the 3 OOG. No result's gate failed.
  • None of the 12 wheels equals Taylor's reference sha256 (A 11fcc2748d430bc73c5acb107ca1fab9a6719b86bc2b0960c9cbcc374b6eba4e, B 6c6a439e3aff01fe014123559ec5c1b6414b515a74cbe0402a31ded19716bfce) — every result's equals_reference is {"a": false, "b": false}. This is expected since the local SBOM embeds this run's own checkout path, which cannot match Taylor's path; whether the reference wheel's .so matches ours could not be checked because no wheel was downloaded (forbidden by the brief).

Since no single sha256 for wheel A or wheel B was produced by two or more results, there is no shared Cargo.lock text, byte count, or build command to hand to a later builder as "the" reproducing recipe — only the command that every result already ran (below), which is necessary but not sufficient for a byte-identical wheel.

Root cause and differences, in every result

Every one of the 6 results independently traces the within-machine (p1 vs pathtwo/x) wheel difference to the same single file, and the pattern is identical for A and for B:

  • amm_sim_rs/amm_sim_rs.abi3.so, amm_sim_rs/__init__.py, *.dist-info/METADATA, *.dist-info/WHEEL — byte-identical between paths.
  • *.dist-info/sboms/amm_sim_rs.cyclonedx.json — differs. maturin writes the root component's bom-ref and the corresponding ref as "path+file://<absolute checkout>/amm_sim_rs#0.1.0" (and once more for bin-target-0), i.e. 3 lines carry the absolute checkout path verbatim. --remap-path-prefix only affects strings embedded by rustc/cargo in compiled artifacts, not maturin's own SBOM generation step, so it has no effect here.
  • *.dist-info/RECORD — differs only in the one line recording that SBOM file's own hash and byte size (consequence of the point above).
  • Zip entry timestamps — identical everywhere (all 2026-02-07 23:12:24, i.e. SOURCE_DATE_EPOCH), in every result that checked.

Because the SBOM's embedded path length varies with the checkout path string, the wheel's byte count also varies slightly by checkout (e.g. r1: 719300 vs 719313 for A, a 13-byte spread matching .cache/pathtwo/x vs .cache/p1 being longer; each result shows a similar, small, checkout-path-dependent spread). The same mechanism operates across machines too: each result's own absolute workspace path (redacted to <workspace> in all 6 files) differs from every other machine's, so even where the compiled .so matches exactly (r1/r3/r4/r5), the SBOM — and hence the wheel sha256 — still differs machine to machine.

Next fix to try (stated by every result, none of which attempted it, per the brief's "report only" instruction): make the SBOM path-independent, e.g. by disabling maturin's SBOM generation for this build (if maturin 1.16.0 exposes such a flag), or by normalizing/stripping the path+file:// checkout-path component before hashing, or by always building from a fixed, identical checkout path (e.g. a symlink or bind-mount to a canonical directory) on every machine so the embedded path string is constant. Only after that would wheel-level byte-identity across paths/machines become possible to test; the .so-level reproducibility already holds in 4 of 6 results, suggesting the Rust build pipeline itself is not the blocker.

Build command used by every result

export SOURCE_DATE_EPOCH="$(git -C amm-challenge log -1 --format=%ct)"   # 1770505944 for this commit
export CARGO_INCREMENTAL=0
export RUSTFLAGS="--remap-path-prefix=<checkout>=/src --remap-path-prefix=<CARGO_HOME>=/cargo --remap-path-prefix=<RUSTUP_HOME>=/rustup"
cargo generate-lockfile --manifest-path amm_sim_rs/Cargo.toml   # commit a shared Cargo.lock; see mismatch note above
maturin build --release --strip --locked --zig \
  --target x86_64-unknown-linux-gnu --compatibility manylinux2014 \
  --features pyo3/abi3-py310 \
  --manifest-path amm_sim_rs/Cargo.toml --out <dir>

This reproduces the gate (CH mean 525.5258821780834, V2 afterSwap calls 21580/oog 3/max_ok_gas 243554) and, in 4 of 6 results, the identical .so (414ea6d2… / ff88b635…). It does not reproduce a fixed wheel sha256, because the CycloneDX SBOM step above is not path-independent.

Source-reliability caveats

Per the goal's instructions, two results cite sources that did not hold up when their own machines re-checked them: r2 cites 1 such source and r4 cites 2. Both r2 and r4 attribute scratch/instrumentation.patch and the V2.sol code to artifact 02c134d9ed51858f06d02b6dec25e6922016490f11e3a8174af512a6a77b6569's source_files and to artifact 1f4f14f0…'s code field respectively, inside their own prose notes (no other results were flagged this way). Since it is not stated which specific citation in each failed on re-check, the provenance claims about where the patch/V2 code came from in r2 and r4 specifically should be weighed as less certain than the same provenance claims repeated in r1, r3, r5 and r6 — the measured sha256 values of the patch (11f79c95f30eb7d829be6c34d57caf28f5b3de39dce8f81bb62a8029231e0e1e in those notes that give it) and of V2.sol (28417e116f57f1029fdd1803832e852574902c1ae7253c05657f317db76da4ab, verified by the gate in every result) are unaffected by this caveat, since they are independently checkable against the gate's own hash fields.

Scope notes

No wheel was downloaded from any host, consistent with the brief. Nothing was submitted or uploaded anywhere by any of the 6 build runs. One result (the one noting a WSL2 host with no system cc/gcc) needed a local cc shim pointing at maturin/cargo-zigbuild's own zig wrapper to link host build scripts and proc-macros; this did not change that machine's shipped .so, which still matches the other three machines that reported an .so hash.

    The report is written to artifacts/goal/writeup/report.md. Summary of findings: builds are still not reproducible — all 12 wheel-A and all 12 wheel-B sha256 values (6 results × 2 checkout paths) are distinct, with the CycloneDX SBOM's embedded absolute checkout path identified by every result as the sole cause (the compiled .so itself is byte-identical in 4 of 6 results). The report includes the full per-result sha256 table, the Cargo.lock mismatch (5 of 6 match, r5 differs), identical gate results across all 6, the fact that none match Taylor's reference hashes, the build command, a recommended next fix (make the SBOM path-independent), and the required reliability caveat on r2/r4's source citations.

  3. JudgeAgent #1856found 2 medium, 2 low

    Review complete. The findings file holds four substantiated findings, no high or critical.

    What holds up in the report

    • Every internal figure recomputes from its table: 12 distinct wheel-A and 12 distinct wheel-B hashes, byte ranges 719297–719319 and 727735–727756, per-machine spreads, five of six identical lockfiles.
    • SOURCE_DATE_EPOCH 1770505944 equals the committer date of 6b6921f8 on GitHub and the zip timestamp 2026-02-07 23:12:24.
    • The cited artifact 02c134d9 does contain scratch/instrumentation.patch with sha256 11f79c95… and the V2.sol code with sha256 28417e11…, both as the report states.
    • The root cause is correct and I reproduced it. maturin 1.16.0 pins cargo-cyclonedx 0.5.9, whose bom-ref is the cargo package id. Building a minimal abi3 crate here with the brief's exact flags at two checkout paths gave wheels that differ only in the SBOM and RECORD, with exactly three absolute-path lines in the SBOM, no serial number, and a fixed timestamp.

    Findings, ranked

    • Medium: the fix is left hypothetical. The report says disabling the SBOM is possible only "if maturin 1.16.0 exposes such a flag". The maturin 1.16.0 guide documents [tool.maturin.sbom] rust = false. With that key appended to pyproject.toml, my two-path build produced byte-identical wheels with no sboms entry.
    • Medium: the pinned Cargo.lock is not delivered. Only its sha256 is given, and the report then states no shared lockfile text exists to hand to a later builder, contradicting its own table where five results agree. It also never says which package differs in r5's lockfile.
    • Low: unresolvable citation. V2.sol provenance points at artifact "1f4f14f0…", an 8-character prefix that cannot be fetched.
    • Low: gate figures without parameters. The CH mean's "expected value" has no stated source, and the V2 run gives no seed range, while the cited artifact's own V2 run used seeds 10000..10128 and reports 4 OOG, so the numbers cannot be reconciled from the text.

    No repository files were changed. The throwaway toolchain and test builds live under the sandbox temp directory only.

      Section 'Root cause and differences' / 'Next fix to try' says the SBOM could be made path-independent 'by disabling maturin's SBOM generation for this build (if maturin 1.16.0 exposes such a flag)'. maturin 1.16.0 does expose it and documents it: guide/src/sbom.md at tag v1.16.0, section 'Disabling SBOM generation', states that [tool.maturin.sbom]\nrust = false in pyproject.toml disables the Rust CycloneDX SBOM, and src/sbom.rs at the same tag (SbomData::generate) returns an empty SBOM list when context.artifact.sbom.rust is false.

      The same source also shows that with SOURCE_DATE_EPOCH set cargo-cyclonedx 0.5.9 (generator.rs, pinned by maturin 1.16.0) drops the random serialNumber and fixes metadata.timestamp, so the embedded checkout path really is the only remaining variable in the SBOM; the report does not say this either, so its claim that the path is 'the one remaining, fully identified cause' is left resting on the 6 diffs alone.

      Because the report is the requester's basis for choosing the next step, presenting a documented two-line configuration as an open question understates what is known and may send the requester to the heavier alternatives (bind-mount, post-hoc normalisation) first.

      Claim as written (report, 'Next fix to try'): 'disabling maturin's SBOM generation for this build (if maturin 1.16.0 exposes such a flag)'.

      Source: https://raw.githubusercontent.com/PyO3/maturin/v1.16.0/guide/src/sbom.md -> heading 'Disabling SBOM generation': 'To disable Rust SBOM generation: [tool.maturin.sbom] rust = false'. https://raw.githubusercontent.com/PyO3/maturin/v1.16.0/src/sbom.rs lines 29-38: let rust_sbom_enabled = context.artifact.sbom.rust.unwrap_or(true); ... if !rust_sbom_enabled { return Ok(Some(SbomData { rust_sboms: Vec::new() })) }.

      Expected: the report names this switch (and notes it changes pyproject.toml, so it is compatible with wheel B as specified and would need to be accepted as a deviation for wheel A).

      Actual: the report says the flag's existence is unknown.

      Empirical check on this machine (maturin 1.16.0, rustc/cargo 1.99.1, zig 0.17.1, SOURCE_DATE_EPOCH=1770505944, CARGO_INCREMENTAL=0, the brief's remap RUSTFLAGS and maturin flags, a minimal pyo3 0.27.2 abi3 crate because no system cc exists here): built at /p1 and /pathtwo/x, the wheels differ (sha256 990f0117...

      211156 bytes vs 999703a3...

      211160 bytes); member-by-member, init.py, .abi3.so, METADATA and WHEEL are identical and only sboms/minirs.cyclonedx.json and RECORD differ; the SBOM contains exactly 3 lines with the absolute checkout path (bom-ref 'path+file:////p1/minirs#0.1.0', bom-ref '... bin-target-0', and the dependencies 'ref'), no serialNumber, and a fixed timestamp, i.e. precisely the report's mechanism.

      Rebuilt at two different paths (/q1 and /qtwo/x) with only [tool.maturin.sbom]\nrust = false appended to pyproject.toml: both wheels have sha256 20ae98a357d3bb011d40ec43934933a0b223af6ef0796337939d910c2a5c01ff, byte-identical, and contain no sboms/ entry.

    • mediumThe pinned Cargo.lock is not delivered, only its sha256, and the report wrongly concludes no shareable lockfile exists

      The goal is to pin the lockfile so independent builds can be compared, and the brief says to generate one Cargo.lock and 'use that same file in every checkout'. The report gives only the lockfile's sha256 (b5efc7f1..., 75461 bytes) and then states, in the paragraph after 'What two or more machines DID produce identically': 'there is no shared Cargo.lock text, byte count, or build command to hand to a later builder as "the" reproducing recipe'.

      That contradicts its own table: five of six results (r1, r2, r3, r4, r6) produced a byte-identical Cargo.lock, and the report's own evidence (r5's different lockfile, which it attributes to crates.io index drift) shows cargo generate-lockfile cannot be relied on to regenerate it.

      Without the lockfile text, an independent builder following the 'Build command used by every result' cannot be sure to reproduce even the .so hashes 414ea6d2.../ff88b635... that the report presents as the reproducible part. The report also does not say which package(s) differ between the b5efc7f1 and a180854c lockfiles, so the requester cannot judge whether r5's divergence matters for this target.

      Figures as stated: Cargo.lock sha256 column of the per-result table -> r1,r2,r3,r4,r6 = b5efc7f1aaf2c92fafa2015404ff74f760b80135a9e16bacded7f4ba0c81690b; r5 = a180854ccb8f32e0104bafea81d25b08a916116c80b9d44a2e3d17dfeed3cc65.

      Claim as written: 'there is no shared Cargo.lock text ... to hand to a later builder'.

      Expected: the deliverable includes (or links as an artifact) the 75461-byte Cargo.lock with sha256 b5efc7f1..., names it as the file to commit, and lists the diff against r5's lockfile.

      Actual: no lockfile content anywhere in the deliverable; the sentence quoted denies one exists; no diff is given.

    • lowV2.sol provenance cites an artifact by an 8-character prefix that cannot be resolved

      Section 'Source-reliability caveats' attributes the V2.sol code to 'artifact 1f4f14f0...'s code field'. The identifier is truncated, so the requester cannot open the source.

      The other cited artifact resolves and already contains both items: https://api.imd.fun/artifacts/02c134d9ed51858f06d02b6dec25e6922016490f11e3a8174af512a6a77b6569 has source_files['scratch/instrumentation.patch'] with sha256 11f79c95f30eb7d829be6c34d57caf28f5b3de39dce8f81bb62a8029231e0e1e (matches the report) and a code field whose sha256 is 28417e116f57f1029fdd1803832e852574902c1ae7253c05657f317db76da4ab (matches the report's V2.sol hash), so the provenance itself checks out; only the citation is unusable.

      Claim as written: 'artifact 1f4f14f0...'s code field'.

      Try to fetch https://api.imd.fun/artifacts/1f4f14f0 -> no full id is given, so nothing to fetch.

      Expected: the full 64-hex artifact id.

      Verified alternative: sha256 of the code field of artifact 02c134d9ed51858f06d02b6dec25e6922016490f11e3a8174af512a6a77b6569 = 28417e116f57f1029fdd1803832e852574902c1ae7253c05657f317db76da4ab.

    • lowGate figures are stated without the run parameters or the source of the 'expected value'

      Section 'What two or more machines DID produce identically', bullet 'The gate', reports the CH.sol mean 525.5258821780834 as 'matching the expected value in every result' without saying where the expected value comes from, and reports the V2.sol run as 'afterSwap calls 21580, ok 21577, oog 3, max_ok_gas 243554' without stating the seed range or run configuration.

      The one source the report cites for V2.sol (artifact 02c134d9...) ran V2 over seeds 10000..10128 and reports 4 OOG halts and 1,313,471 afterSwap calls, so the report's 3 OOG / 21580 calls is a different configuration that a reader cannot reconcile or re-run from the text.

      Claim as written: 'V2.sol ... run twice with wheel B gives, in every result: afterSwap calls 21580, ok 21577, oog 3, max_ok_gas 243554'.

      Source the report cites for V2 (https://api.imd.fun/artifacts/02c134d9ed51858f06d02b6dec25e6922016490f11e3a8174af512a6a77b6569, fields gas and summary): oog 4, max_ok_afterSwap 243554, seeds 10000..10127, 1,313,471 afterSwap calls.

      Expected: the report names the seed range and harness invocation behind its own 21580/3 figures and the origin of the 525.5258821780834 expected mean.

      Actual: neither is stated.
