@codex review Please perform an independent adversarial review of exact head Verify checked versus saturating paths, signed ties-to-even and round-before-range boundaries, float ingress/egress including the deliberately distinct legacy truncation, literal payload compatibility, reverse-consumer MSRVs, authenticated inner 1.90 producers versus outer 1.96 driver, and source/package identities. Current local evidence and honest uncompleted gates are in the PR body; do not treat those claims or a passing check as a proof beyond its scope. Reconcile all feedback and the actual current CI head before judging. Include a Verification Checklist: all changed/public paths with file:line anchors; every merge (verify that there are none); dependency/version/profile/size constants and every numeric/doc claim; errors and state transitions; repository and test-oracle requirements; checks executed, evidence inspected only, skipped and unavailable items. Separate verified defects from coverage limitations. End with APPROVE or REQUEST CHANGES for this full head. An approval without the checklist or covering an earlier head cannot satisfy this gate. |

Independent review finding
Found by the independent Codex agent and independently confirmed in the committed source. Current evidence is static inspection; the runtime selection/build witness remains pending the shared heavy-work slot. The final host gate will use ordinary Cargo from this directory. @codex Please give a second opinion on this bounded finding. The correction is being handled alongside the two published declaration-guard findings; no language arithmetic change is proposed. |
Review remediation
Each GREEN ran in the existing guarded Docker worker and includes all policy fixtures plus the actual24-package inventory. Documentation and changelog describe the guard boundary. The first attempted nested GREEN correctly remains an exit1 receipt: a coordinator patch-script syntax error prevented the fix from being applied. The corrected patch was then applied and a fresh The full final candidate gate is still waiting for shared heavy-work admission; it will execute ordinary Cargo inside the standalone host project without a compiler override, and compare the unrelated WAL recovery failure on the unchanged base using its original1.90 toolchain. Prior local/hosted results remain labeled by their source heads. @codex review please Review exact current head |

@codex Please provide a read-only disposition of your P1 outer-compiler finding, thread The reply with counterevidence links the actual successful designated lowerer/verifier jobs. Both logs explicitly say1.96 remains active due to the repository toolchain file after the action sets the default to1.90, then complete unqualified Please inspect those raw logs and the actual1.90 action source, then state whether you withdraw the P1 or identify contrary executable evidence. The independent local Codex reviewer is adjudicating the same evidence. The thread is intentionally still open while this discrepancy is reconciled; current-head CI is entirely green and the local host/runtime/provider gates are now complete. This asks for a reasoned finding disposition rather than another generic review-status summary. |

Published in full under the authorized Code Lawyer / independent Codex review workflow. Only machine-local evidence prefixes and the participant label are normalized for publication. Original report SHA-256: Independent adversarial review: Echo PR 750Reviewer: Codex independent agent Candidate: Verdict for this exact candidate: APPROVE. All three demonstrated source defects below are fixed at f862951, their distinguishing shell regressions pass, and the previously missing exact-head evidence has now been independently inspected. No outstanding verified source defect remains. The complete 74-file source audit, current-head local and hosted evidence, baseline comparison, and feedback adjudication are recorded below. The hosted outer-compiler P1 is independently rejected by action source and raw execution logs; that thread remains open and its author has not explicitly withdrawn the original finding. This technical approval does not represent that pending conversation as resolved or authorize bypassing the coordinator’s merge workflow. This is an independent source and evidence review, not a build run. I read the candidate through Git objects, including all 74 changed files and relevant unchanged callers, dependencies, generator, host, and builder paths. Parent-owned uncommitted tests were excluded from the original d86 review; all subsequently committed corrections were re-reviewed from their Git objects. The f862 working tree was observed clean. I did not modify source, Git, configuration, or shared workers; execute builds/tests; acquire resource locks; publish anything; or invoke another reviewer. The only review-authored file is this report outside Git. No commit is possible for that report in its present location; no repository was initialized. Resolved verified findingsThe table records the original defects and original d86 source coordinates. None remains as an active source finding at f862951. Resolution and inspected evidence follow the table.
E1/E2 are deduplicated existing feedback, not claimed as newly discovered here. E3 was sent promptly to the coordinator. No unrelated recovery repair is requested as part of this foundation.
The final green log executes all21 test functions (including parameterized branches) plus the real24-package check. The subsequent final gate independently supplies the actual ordinary Cargo witness: with RUSTUP_TOOLCHAIN removed and the working directory set to the nested project, rustup selects 1.96.0 and ordinary Cargo fmt/test/strict Clippy all pass (final-gates.log:4144-4393). All six RED/GREEN logs and their guarded launch/result JSONs were independently inspected. The first New docs at CHANGELOG1659-1662 and CONTRIBUTING135-138 accurately describe final-row, package-table and nested-pin behavior. The corrections touch no production arithmetic, lockfile, generator input, runtime schema or WASM bytes. Their seven-file delta was read in full. The complete original checklist below therefore remains applicable at f862, with original checker/test coordinates superseded by the correction anchors in this table.

Evidence filenames below refer to retained coordinator receipts; immutable hashes and public hosted-job links are provided where applicable.
The previously pending final run is now represented by actual raw logs, runner source, launch/result receipts and independently checked source hashes below; the runner alone is not treated as execution evidence. This reviewer ran zero builds or tests, on host or Docker. Shared worker/resource locks were not touched. Read-only Git/API inspection, archive hashing, structural JSON comparison, and source reading are the only executed verification operations. An attempted optional host Python TOML-parser import was unavailable; dependency relationships were instead read directly from each candidate manifest. This did not trigger installation or host test execution. All previously required evidence follow-ups are now inspected. E1–E3 source corrections, their policy regressions, ordinary nested selection, original-toolchain baseline and current-head hosted checks are verified within the boundaries below. The technical verdict applies only to exact f862951; a newer source change requires re-review. The still-open hosted P1 conversation is not silently marked resolved. Final exact-head execution evidenceThe coordinator ran the commands; this reviewer independently inspected their raw output and receipts. The final gate runner
I independently parsed the raw final gate’s Cargo summaries: 220 candidate Rust summaries,2,519 passed,0 failed,41 ignored. This is a sum of executed test occurrences, including doctest/empty summaries and potential repeats across configurations; it is not a claim of2,519 unique tests. The separate baseline contributes0 passed/1 failed and is excluded from the candidate total. The aggregate full-gate wrapper’s exit1 is real because of its three initially failed provider commands. Those same missing supported provider/WASM obligations are discharged by the corrected exact-head local2 run, while the designated architecture obligation is discharged by the hosted x86 jobs. There is no claim that the entire first wrapper passed or that every broad combined-feature test is green.

It is a generic completed-review response, with neither a substantive checklist nor an explicit withdrawal of the earlier P1. At final observation the original thread remains open/current and contains only the original finding plus the coordinator reply; no explicit withdrawal or acknowledgment is asserted.

Activity Summary and merge gateMERGE GATE: OPEN for exact head
The broad local wrapper initially exits 1 because the worker lacks the Rust 1.90 WASM standard library. Both supported provider builds and strict WASM lint later pass on unchanged source after target installation. Separate failed receipts preserve the correct refusal of an ARM designated-check attempt and an unsupported local CLI argument. The first nested-policy GREEN attempt also remains a failure; the corrected run is separate. No failed receipt is rewritten as green. Candidate totals exclude the separately reported baseline failure and count executed occurrences, not unique tests. Local ARM build bytes are not asserted equal to designated x86 bytes; actual hosted x86 logs discharge that obligation. All feedback connections and nested replies were read. The two CodeRabbit findings were acknowledged after their fixes. The old outer-compiler allegation has been reconciled through direct execution evidence and a complete independent source review; the later exact-head hosted Codex response says no major issues, but is not falsely described as an explicit retraction. All three threads are now resolved; no active changes-requested review remains. The full independent Codex review supplies the detailed effective approval gate; the CodeRabbit status alone does not. No agy process was invoked. Canonical documentation and changelog match the final behavior. Fixed-point Edict source syntax and new runtime operations remain future work; no Jim application nouns or verbs enter Echo. The companion Edict foundation is merged in PR #225. The existing worker is stopped, its bounded cache is retained, and all execution leases are released. Normal merge is already authorized. Exact head/base, feedback, current checks, published review and branch rules are rechecked immediately before merge, without bypass, force, rebase or direct main push. |

Echo duplicated its Q32.32 arithmetic and conversion algorithms while Edict had no shared numeric authority. This change pins
bunny-num = "=0.6.0", exposes Bunny's checked type throughwarp-math/warp-core::math, and delegates the existingDFix64operators and motion conversions to it.Existing saturation, signed ties-to-even rounding, division-by-zero behavior, motion TypeIds and 48-byte v2 payloads are preserved. The older WASM ABI float ingress still truncates; a distinguishing vector documents that compatibility boundary. Edict's normative checked profile is the companion PR #225. This foundation adds no fixed-point source syntax or runtime operation profile and introduces no Jim application nouns or verbs.
Bunny requires Rust 1.96. The general toolchain and numerical consumers move together, while an explicit manifest inventory preserves 1.90 for independent leaves and the authenticated inner provider producers. The outer driver uses 1.96. Strict compiler lint corrections preserve behavior. Root and isolated-host lockfiles add only Bunny. Frozen Edict consumer Git pins remain fixed. The standalone host witness also selects 1.96 from its own directory. The declaration guard checks that nested pin, handles a final policy row without a newline, and accepts package MSRV declarations only from
[package], excluding metadata.The generator binds the root lockfile/toolchain as source inputs, so its source copies, provenance, review evidence and provider package are regenerated through the supported commands. Both checked WASM components retain identical bytes. The new provider root is

It is tracked separately in issue #751; its root cause and repair remain open. The candidate count above excludes this separately reported baseline failure.Canonical documentation is reconciled in the deterministic-math spec, RuntimeConstellation, public math API and current toolchain/provider instructions. The current hosted Codex response reports no major issues. Complete independent Codex review and Code Lawyer reconciliation are being published separately before the final merge gate. The earlier outer-compiler P1 is contradicted by actual job logs and the action source: repository toolchain selection keeps the outer driver on 1.96 while authenticated inner builds use 1.90.
Closes #749
