Rebuild the Rust coverage LLVM runtime-boundary repair from PR-base snapshot 1131b1bbafb24e455fc8619cdf316813e8721861. Historical PR #816 and every predecessor-head check, review, approval, comment, and synthetic merge result remain non-transferable.
Exact identity and scope repair
exact current head: 7af91fbe22c8db9ee4ec737521a0883fbddfddd2;
independently re-resolved live protected main tip: 6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba;
GitHub state: Ready and mechanically mergeable.
After the previously bounded head c100cca8e2ba5a5c0f7794e088c5a091dc135e8d, unrelated architecture, trusted-lock materializer, temporary repair-workflow, and repair-script commits entered this branch. A non-destructive forward commit now points to the exact previously bounded tree. GitHub compare reports zero changed files between c100cca8... and the current head. No force-push, rebase, history rewrite, predecessor check transfer, or workflow-gate weakening was used.
Every result from all predecessor heads is historical only. The current head must regenerate exact-head evidence.
Test-first lineage and bounded contract
RED head 3887faba96b50f34cff0ad58e5706427d818ec7d established the missing LLVM runtime-boundary contract. The implementation requires:
Debian llvm-19 in the digest-pinned trusted coverage image;
exact LLVM_COV=/usr/bin/llvm-cov-19 and LLVM_PROFDATA=/usr/bin/llvm-profdata-19 bindings;
build-time executable checks before admitting the pinned cargo-llvm-cov archive;
literal propagation through the isolated docker run; and
exact-value plus executable revalidation inside the networkless runtime before Rust coverage.
The repair preserves immutable image and cargo-llvm-cov identities, exact-head materialization, --network=none, credential/Git isolation, native-fuzz separation, reviewer identities, 100% coverage policy, and branch protection. No fallback to unversioned LLVM binaries is permitted.
Verification posture
The previously bounded tree completed the Rust coverage toolchain quality workflow, Strix, CodeQL, Python Security, Semgrep, aggregate Security Scan, Secret Scan, SBOM, Scorecard, and OSV successfully, and its review threads were resolved. Those results prove the prior head only.
Current-head quality, security, supply-chain, and semantic-review evidence must all regenerate. Pending, queued, skipped, cancelled, stale, predecessor-head, local-only, author-only, status-only, synthetic, or model-only evidence is not acceptance.
Merge gate
Merge or auto-merge only after the unchanged current head has terminal-success required gates, zero valid unresolved findings, a qualifying current-head semantic verdict, the independent non-author formal approval required by live rules, a compatible live base, and ordinary expected-head merge authority. No admin bypass, self-approval, synthetic approval, protection weakening, or predecessor evidence transfer is requested.

The PR is intended to enforce LLVM 19 for Rust coverage, but the helper and contract tests still permit or fail to fully verify deviations from that boundary, and earlier dependency-locking and package-verification concerns remain unresolved. The PR is not merge-ready until these bounded correctness and supply-chain controls are addressed.

Complete the bounded Rust coverage runtime-boundary repair on exact current Draft head edddecdfa2b66b61f472db8f754270ffc2fd147c, protected base 1131b1bbafb24e455fc8619cdf316813e8721861. The authoritative .github/workflows/opencode-review-dispatch.yml blob is still b17cf37758abf508d42a7bed8e896bdfb43adc1d; abort and re-read if either identity moves.
Exact-head security/supply-chain workflows are GREEN; only OpenCode Rust Coverage Toolchain Quality CI is RED. The current production diff already satisfies the build-image half of the permanent contract: Debian llvm-19, exact ENV LLVM_COV=/usr/bin/llvm-cov-19, exact ENV LLVM_PROFDATA=/usr/bin/llvm-profdata-19, and build-time executable validation before the pinned cargo-llvm-cov archive. Implement only the remaining runtime-boundary contract:
In the existing isolated docker run --rm ... "$coverage_tool_image" launch, propagate the reviewed constants literally before the image argument: --env LLVM_COV=/usr/bin/llvm-cov-19 and --env LLVM_PROFDATA=/usr/bin/llvm-profdata-19.
Inside the isolated-runtime ensure_rust_toolchain(), fail closed unless ${LLVM_COV:-} is exactly /usr/bin/llvm-cov-19 and ${LLVM_PROFDATA:-} is exactly /usr/bin/llvm-profdata-19.
In that same runtime validation, require test -x "$LLVM_COV" and test -x "$LLVM_PROFDATA" before the first cargo llvm-cov invocation.
Keep tests/test_opencode_rust_coverage_toolchain_contract.py authoritative; do not weaken or bypass it. Preserve the digest-pinned image, pinned cargo-llvm-cov artifact/SHA-256, --network=none, exact-head/base materialization, credential/Git isolation, reviewer identities and credential chain, NVIDIA NIM usage, native-fuzz separation, and existing 100% coverage policy. Do not add any temporary, one-shot, self-modifying, encoded-patch, branch-local repair, competing branch-writer, or write-capable helper workflow.
After the minimal permanent edit, rerun the focused contract plus complete central tests/security/supply-chain gates on the exact new head, and keep Draft until all required exact-head evidence, current automated review, zero actionable threads, qualifying independent non-author approval, and branch protection are satisfied. Do not reuse PR #816 evidence.
@opencode-agent Please repair the exact current RED head only if it is still edddecdfa2b66b61f472db8f754270ffc2fd147c on base 1131b1bbafb24e455fc8619cdf316813e8721861, and only if .github/workflows/opencode-review-dispatch.yml still has blob b17cf37758abf508d42a7bed8e896bdfb43adc1d. Refetch all three identities immediately before writing; if any moved, do not mutate and instead review the new state.
The current exact-head OpenCode Rust Coverage Toolchain Quality CI is RED while the same-head security/supply-chain workflows are green. Preserve the existing test-first contract and make only the minimum production repair for the three remaining assertions:
In the existing isolated docker run --rm --init --network=none invocation, before "$coverage_tool_image", propagate the reviewed constants literally: --env LLVM_COV=/usr/bin/llvm-cov-19 \\ --env LLVM_PROFDATA=/usr/bin/llvm-profdata-19 \\
In isolated-runtime ensure_rust_toolchain(), after the existing cargo-llvm-cov availability check and before ensure_rust_gpu_adapter, fail closed unless ${LLVM_COV:-} is exactly /usr/bin/llvm-cov-19 and ${LLVM_PROFDATA:-} is exactly /usr/bin/llvm-profdata-19.
In that same runtime validation, require literal executable checks test -x "$LLVM_COV" and test -x "$LLVM_PROFDATA" before any cargo llvm-cov invocation. Do not accept unversioned fallbacks.
Keep the digest-pinned tool image, cargo-llvm-cov 0.8.7 artifact/SHA-256, --network=none, credential/Git isolation, reviewer identities/credential chain, and coverage policy unchanged. Run the focused tests/test_opencode_rust_coverage_toolchain_contract.py first, then the relevant complete central suite. If green, update the PR with exact new head evidence; do not self-approve, undraft, merge, or reuse #816 evidence.
Repair the exact current Draft head 4f57decdd3641b54a42ce78253c7c027234d6206 only, on protected base 1131b1bbafb24e455fc8619cdf316813e8721861. Before writing, refetch and require both the PR head and .github/workflows/opencode-review-dispatch.yml blob to remain unchanged; the live workflow blob observed now is b17cf37758abf508d42a7bed8e896bdfb43adc1d.
Exact-head OpenCode Rust Coverage Toolchain Quality CI run 31246896010, job 93076884382, checked out this literal head with persisted credentials disabled and failed exactly the three permanent LLVM runtime-boundary contracts:
only one test -x "$LLVM_COV" / test -x "$LLVM_PROFDATA" pair exists; add the second validation inside the isolated runtime;
propagate literal --env LLVM_COV=/usr/bin/llvm-cov-19 and --env LLVM_PROFDATA=/usr/bin/llvm-profdata-19 through the existing docker run --rm boundary before the trusted coverage image;
inside the isolated-runtime ensure_rust_toolchain(), fail closed unless ${LLVM_COV:-} and ${LLVM_PROFDATA:-} exactly equal /usr/bin/llvm-cov-19 and /usr/bin/llvm-profdata-19, then require both paths executable before any cargo llvm-cov invocation.
Make only the minimum production correction in .github/workflows/opencode-review-dispatch.yml. Preserve the digest-pinned coverage image, installed llvm-19, image-level ENV bindings and build-time checks, cargo-llvm-cov pinned archive/SHA, exact-head materialization, --network=none, credential/Git isolation, reviewer identities and credential chain, native-fuzz separation, and 100% coverage policy. Do not accept unversioned LLVM fallback, weaken the tests, alter branch protection, or broaden the diff.
Run tests/test_opencode_rust_coverage_toolchain_contract.py first, then the complete current-head central/Strix quality contracts and syntax checks. If the head or target blob moved, do not write; reconcile the new state instead.
Exact-head GREEN repair for current Draft head 4f57decdd3641b54a42ce78253c7c027234d6206. Before any write, refetch the PR head/base and .github/workflows/opencode-review-dispatch.yml; the observed workflow blob is b17cf37758abf508d42a7bed8e896bdfb43adc1d. If either moved, do not write.
The exact-head focused quality run 31246896010 / job 93076884382 proves the remaining contract is exactly three RED failures; Security Scan, SAST, CodeQL, Python Security, Secret Scan, OSV, Scorecard, and SBOM are otherwise successful on this head. Preserve the already-green image/build boundary and implement only the missing runtime boundary in .github/workflows/opencode-review-dispatch.yml:
In the existing isolated docker run, before "$coverage_tool_image", propagate literal --env LLVM_COV=/usr/bin/llvm-cov-19 and --env LLVM_PROFDATA=/usr/bin/llvm-profdata-19.
Inside the isolated runtime ensure_rust_toolchain(), fail closed unless ${LLVM_COV:-} equals /usr/bin/llvm-cov-19 and ${LLVM_PROFDATA:-} equals /usr/bin/llvm-profdata-19 exactly.
In that same runtime validation, require test -x "$LLVM_COV" and test -x "$LLVM_PROFDATA" before the first cargo llvm-cov invocation.
Do not add unversioned LLVM fallback, change the digest-pinned coverage image, cargo-llvm-cov artifact/hash, --network=none, credential/Git isolation, reviewer identity/key chain, coverage thresholds, native-fuzz separation, or any workflow entrypoint. Keep the existing RED tests unchanged except for any strictly necessary test maintenance caused by current protected main.
Run python -m pytest -q tests/test_opencode_rust_coverage_toolchain_contract.py, the complete central pytest/coverage/docstring gates, compile/syntax/diff hygiene, and let exact-head Strix/security/supply-chain workflows rerun. Commit normally to the existing branch only after revalidating the pre-write head/blob identities. Keep Draft; do not approve, merge, or create temporary/write-capable repair workflows.
Exact-head bounded GREEN repair for 4f57decdd3641b54a42ce78253c7c027234d6206; target .github/workflows/opencode-review-dispatch.yml blob is b17cf37758abf508d42a7bed8e896bdfb43adc1d. Do not write if either identity has moved.
Current-head OpenCode Rust Coverage Toolchain Quality run 31246896010, job 93076884382, is an intentional RED contract with exactly three failures. The trusted image already satisfies build-time provisioning; finish only the missing runtime boundary:
In the existing isolated docker run --rm --init --network=none invocation, before "$coverage_tool_image", propagate the reviewed literal bindings: --env LLVM_COV=/usr/bin/llvm-cov-19 --env LLVM_PROFDATA=/usr/bin/llvm-profdata-19
Inside the isolated-runtime ensure_rust_toolchain() path, fail closed unless ${LLVM_COV:-} is exactly /usr/bin/llvm-cov-19 and ${LLVM_PROFDATA:-} is exactly /usr/bin/llvm-profdata-19.
In that same runtime validation, require test -x "$LLVM_COV" and test -x "$LLVM_PROFDATA" before the first cargo llvm-cov invocation.
Preserve the digest-pinned image, llvm-19 package, build-time executable checks, pinned cargo-llvm-cov archive/SHA-256, --network=none, credential/Git isolation, sandbox UID/GID, native-fuzz separation, exact-head coverage evidence, reviewer identities/credentials, and branch protection. Do not add unversioned LLVM fallback, move coverage outside the sandbox, change unrelated workflow behavior, weaken the RED tests, or create temporary/self-modifying/write-capable workflows.
Run the focused LLVM contract first, then the complete central pytest suite, bash scripts/ci/test_strix_quick_gate.sh, Bash/Python syntax/compile gates, exact 100% production statement/branch/public-docstring contracts, and all security/supply-chain checks on the resulting unchanged head. Keep Draft until every exact-head gate and current-head review is clean; do not merge or synthesize approval.
@cwl-noema-review @opencode-agent Review only exact current head 7f9c197e2c03e19330a21bcc11d7066d6a9543f1. Protected main is an ancestor at 6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba; all ten exact-head quality/security/supply-chain workflows are successful and no inline thread is open. Verify exact LLVM 19 image installation, literal LLVM_COV/LLVM_PROFDATA propagation through the networkless Docker boundary, in-runtime exact-value/executable revalidation before cargo-llvm-cov, immutable tool/archive pins, no unversioned fallback, and unchanged credential/reviewer authority. Review only; do not modify, merge, retarget, or alter branch protection.
@seonghobae I will review only head 7f9c197e2c03e19330a21bcc11d7066d6a9543f1.
I will verify the LLVM 19 image setup, literal Docker environment propagation, runtime validation before cargo llvm-cov, immutable pins, absence of unversioned fallbacks, and unchanged credential and reviewer authority. I will not modify, merge, retarget, or change branch protection.

Pull request overview
OpenCode reviewed the current-head mergeability evidence and changed-file flow before approval, then found merge conflicts on the affected path.
Findings
1. HIGH Merge Conflict Guidance - Resolve the PR branch against the latest base branch
Problem: GitHub reports mergeStateStatus DIRTY for this pull request.
Root cause: Branch fix/opencode-rust-coverage-runtime-boundary-main cannot be merged cleanly into main; the changed-file flow below shows which review/runtime path is blocked by the conflict.
Fix: Merge or rebase the latest main into fix/opencode-rust-coverage-runtime-boundary-main, resolve conflict markers in the PR branch, rerun the focused checks, and push the same branch.
Repair commands:
gh pr checkout 827 --repo ContextualWisdomLab/.github
git fetch origin main
git merge --no-ff origin/main # or: git rebase origin/main
git status --short
# resolve files, then git add <resolved-files># merge path: git commit# rebase path: git rebase --continue
git push origin HEAD:fix/opencode-rust-coverage-runtime-boundary-main
# rebase path only: git push --force-with-lease origin HEAD:fix/opencode-rust-coverage-runtime-boundary-main
Regression test: Keep OpenCode approval gated on mergeability so model-output failures cannot approve a conflicted PR.
Head branch: fix/opencode-rust-coverage-runtime-boundary-main

Pull request overview
OpenCode reviewed the current-head bounded evidence and requested changes before merge.
Findings
1. P2 .github/workflows/opencode-rust-coverage-toolchain-quality-ci.yml:1 - Workflow paths filter references a documentation file absent at current head
Problem: The new workflow's on.pull_request.paths filter (line 9) references docs/doctoring/opencode-rust-coverage-runtime-boundary.md, but the trusted current-head docs tree contains only docs/doctoring/strix-legal-git-paths.md, docs/doctoring/strix-nvidia-nim-not-found-fallback.md, docs/doctoring/strix-quality-timeout-fixtures.md, and docs/doctoring/trusted-uv-lock-materialization.md. The referenced doc does not exist, so the trigger path is permanently inert and the LLVM 19 runtime-boundary contract implemented by tests/test_opencode_rust_coverage_toolchain_contract.py has no companion documentation.
Root cause: The runtime-boundary documentation intended to accompany the LLVM repair (matching the repo docs/doctoring pattern used for the strix fixture budget) was never committed while the workflow paths filter was written to include it.
Fix: Add docs/doctoring/opencode-rust-coverage-runtime-boundary.md documenting the LLVM_COV/LLVM_PROFDATA bindings, the image RUN test -x verification, the docker --env propagation, and the fail-closed guard; or remove the 'docs/doctoring/opencode-rust-coverage-runtime-boundary.md' entry from the paths filter if the doc is not intended.
Regression test: Extend tests/test_opencode_rust_coverage_toolchain_contract.py to parse the workflow YAML and assert every pull_request paths entry resolves to an existing file, then run: python3 -m pytest tests/test_opencode_rust_coverage_toolchain_contract.py
Suggested diff: posted in this finding's inline review thread.
Summary
Reviewed PR #827 (fix(coverage): replace stale LLVM runtime-boundary repair) on ContextualWisdomLab/.github at head 7f9c197. Inspected .github/workflows/opencode-review-dispatch.yml (llvm-19 apt provisioning, Dockerfile ENV LLVM_COV/LLVM_PROFDATA with RUN test -x build guards, sandbox docker --env propagation, fail-closed guard in ensure_rust_toolchain), the new .github/workflows/opencode-rust-coverage-toolchain-quality-ci.yml, strix-changed-path-quality-ci.yml (step-scoped STRIX_TEST_PROCESS_TIMEOUT_SECONDS=3 / STRIX_TEST_FAKE_SLEEP_SECONDS=5 env), CHANGELOG.md, docs/doctoring/strix-quality-timeout-fixtures.md, tests/test_opencode_rust_coverage_toolchain_contract.py, and tests/test_strix_quality_timeout_fixture_budget.py. Blocking: the new workflow's pull_request paths filter (line 9) names docs/doctoring/opencode-rust-coverage-runtime-boundary.md, absent from the current-head docs tree (only strix-legal-git-paths.md, strix-nvidia-nim-not-found-fallback.md, strix-quality-timeout-fixtures.md, trusted-uv-lock-materialization.md exist under docs/doctoring); add the doc or drop the path. Approval sufficiency: REQUEST_CHANGES - positive evidence supports the LLVM guard and fixture budget, but the dangling doc reference must be resolved first. Verification posture: Coverage execution evidence Result PASS (supported repository test suites passed); no completed failed GitHub Checks at head; no unresolved review threads; mergeStateStatus blocked is branch policy, not conflict. Linter/static: shell blocks use set -euo pipefail, bash -n on strix gate, compileall and git diff --check wired into CI. TDD/regression: test_opencode_rust_coverage_toolchain_contract.py runs in the new workflow; fixture-budget test added to strix paths and compileall. Coverage: coverage execution evidence PASS with --fail-under=100 contract. Docstring coverage: configured docstring gates passed per coverage evidence. DAG: source-backed head flow opencode-review-dispatch.yml coverage image -> LLVM 19 ENV/RUN test -x -> docker --env propagation -> ensure_rust_toolchain fail-closed guard -> new quality workflow contract test. DDD/domain: workflow/CI domain only. CDD/context: new workflow context consistent with sibling quality workflows (harden-runner, exact-head checkout, hash-locked pip). Similar issues: CodeRabbit rate-limited with no substantive claims; historical bot prompts untrusted. Claim/concept check: CHANGELOG entry matches strix env values and docs. Standards search: N/A - no external standard claimed. Compatibility/convention: immutable action pins and multi-word naming (LLVM_COV, LLVM_PROFDATA, STRIX_TEST_PROCESS_TIMEOUT_SECONDS, STRIX_TEST_FAKE_SLEEP_SECONDS) follow repo convention; no schema/API objects changed. Breaking-change/backcompat: no public API changes; env additions additive. Implementation completeness: LLVM guard and fixture budget fully implemented with tests; the referenced runtime-boundary doc is the missing piece. Performance: 3s/5s fixture budgets keep the strix job inside its limit. Developer experience: new workflow automates the LLVM runtime-boundary contract on dispatch workflow changes; DX surfaces judged from workflow files and contract test wiring. User experience: non-web surfaces reviewed - CI step summaries, workflow trigger behavior, docs. Visual/DOM: N/A non-web; reviewed workflow/review-comment surfaces instead. Accessibility/i18n: N/A non-web. Supply-chain/license: hashed pip install, pinned action SHAs, pinned cargo-llvm-cov v0.8.7 sha256; no new dependencies. Packaging: python 3.14 pytest suite present; no unpackaged source surfaces. Security/privacy: contents: read only, egress audit, exact-head checkout with persist-credentials false, fail-closed toolchain validation, no secrets exposed.

Result: REQUEST_CHANGES
Reason: The new OpenCode Rust Coverage Toolchain Quality CI workflow triggers on docs/doctoring/opencode-rust-coverage-runtime-boundary.md, but the trusted current-head docs tree does not contain that file; the trigger path is permanently inert and the LLVM runtime-boundary contract documented by name has no companion doc.

Pull request overview
OpenCode reviewed the current-head evidence but found unresolved reviewer or review-agent threads before approval.
Findings
1. HIGH .github/workflows/opencode-review.yml:1 - Unresolved reviewer thread blocks automated approval
Problem: OpenCode reached an APPROVE control result, but the approval step found unresolved, non-outdated human or review-agent thread evidence on the current pull request.
Root cause: Reviewer and review-agent feedback can arrive after bounded model evidence is prepared, so the approval step must re-query GitHub immediately before publishing an approval.
Fix: Address or resolve the listed reviewer thread(s), then re-run OpenCode on the current head.
Regression test: Keep the approval gate querying reviewThreads(first: 100) after model output and before create_pull_review APPROVE, including bot review agents other than OpenCode itself.

Do not transfer predecessor finding state or infer qualifying independent human approval.
Dismissed because its sole exact-head blocker was the unresolved predecessor finding thread, which is now resolved with exact-head evidence. At c100cca8e2ba5a5c0f7794e088c5a091dc135e8d, the required doctoring file exists, the watched-path regression covers it, and all ten current-head workflows are terminal-success. This dismissal is not approval, qualifying human review, merge authority, base freshness, or protected-main acceptance.

Stale comment
Verdict
REQUEST_CHANGES on 55a7292a. This head is not a Rust coverage repair.
The coverage sandbox measures untrusted current-head source. scripts/ci/ensure_rust_llvm19.sh therefore cannot bind the coverage producer. .github/workflows/opencode-review-dispatch.yml on this head matches main blob 83f6830d5c21a324b4dbcd4e5c21a07968994b81 and contains no llvm-19 package, no ENV LLVM_COV / ENV LLVM_PROFDATA, no Docker --env literals, and no ensure_rust_toolchain guard. cargo llvm-cov still follows ambient PATH.
The previously approved head 2acaa179 already had those trusted 19 lines. Removing them to keep the review-dispatch blob unchanged moved the check into a file the PR can rewrite.
Next action
Restore the trusted producer pin in default-branch opencode-review-dispatch.yml and pair REVIEW_DISPATCH_BLOB_SHA in the same change. Do not merge this head as a coverage fix. The landing vehicle with that restore is the successor opened from this run.
Do not treat predecessor approvals, predecessor checks, or helper string-match tests as current-head evidence.

These defaults are caller-selectable. A pull-request or sandbox environment can set LLVM_COV_PATH / LLVM_PROFDATA_PATH to match LLVM_COV / LLVM_PROFDATA and pass the helper while cargo llvm-cov uses a different producer.
The helper is also current-head source, so even a hardcoded version is not the trust boundary. Restore the llvm-19 image install, ENV, RUN test -x, Docker --env, and ensure_rust_toolchain guard in trusted .github/workflows/opencode-review-dispatch.yml.

This watch list no longer includes .github/workflows/opencode-review-dispatch.yml. Removing the trusted 19-line LLVM binding from that workflow does not retrigger this job, so the permanent contract cannot catch the regression this head introduced.
Add the dispatch workflow back to on.pull_request.paths and assert the image / Docker / ensure_rust_toolchain literals in tests/test_opencode_rust_coverage_toolchain_contract.py.

This record tells operators the helper is the binding and that opencode-review-dispatch.yml must stay byte-for-byte. That is the opposite of the trust boundary: the coverage image and ensure_rust_toolchain guard in the default-branch workflow are the only place a PR cannot retarget the producer.
Rewrite this as producer-selection (path pin + test -x), not package integrity, and tell the operator to rebuild the trusted image when the LLVM 19 path message appears.

LLVM 19 기준 경로를 외부 환경에서 재정의할 수 없게 하세요.
LLVM_COV_PATH와 LLVM_PROFDATA_PATH가 외부 환경에서 덮어써집니다. 호출자가 다른 LLVM 버전 또는 버전이 지정되지 않은 실행 파일을 지정하면, Line 8-11의 검사도 그 경로를 기준으로 통과합니다. 그러면 Rust 커버리지 검사가 LLVM 19를 사용한다는 보장이 사라집니다.
두 경로를 리터럴 상수로 고정하세요. 현재 tests/test_opencode_rust_coverage_toolchain_contract.py도 fallback 대입 문자열을 검사하므로, 고정된 상수와 override 거부를 검사하도록 함께 갱신하세요.

Do not merge this PR
Head still omits the trusted LLVM 19 producer pin in .github/workflows/opencode-review-dispatch.yml. The helper-only extract cannot bind the coverage producer because the sandbox measures untrusted current-head source.
Landing vehicle:#1057a2d4924f restores the trusted 19 lines, pairs REVIEW_DISPATCH_BLOB_SHA=de1c4800d362bda4a90c31a0c8e39687a782afb4, and fail-closes when that pin drifts.
Next operator action
Merge #1057 after its required checks complete, rebuild the trusted coverage image from default-branch opencode-review-dispatch.yml, then close this PR. Do not open a third LLVM-pin PR.
This head (55a7292a) keeps the LLVM 19 boundary in scripts/ci/ensure_rust_llvm19.sh and leaves .github/workflows/opencode-review-dispatch.yml off the hashed review-dispatch identity. The coverage sandbox measures untrusted current-head trees, so a helper-only pin cannot bind the producer.
Next operator action: merge #1057 (a2d4924f) instead. That head restores the trusted 19-line pin in the coverage image, docker run --env, and ensure_rust_toolchain, and fail-closes when REVIEW_DISPATCH_BLOB_SHA drifts. Do not merge this PR while it still omits those trusted lines.

1131b1bbafb24e455fc8619cdf316813e8721861. Historical PR #816 and every predecessor-head check, review, approval, comment, and synthetic merge result remain non-transferable.Exact identity and scope repair
7af91fbe22c8db9ee4ec737521a0883fbddfddd2;1131b1bbafb24e455fc8619cdf316813e8721861;maintip:6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba;After the previously bounded head
c100cca8e2ba5a5c0f7794e088c5a091dc135e8d, unrelated architecture, trusted-lock materializer, temporary repair-workflow, and repair-script commits entered this branch. A non-destructive forward commit now points to the exact previously bounded tree. GitHub compare reports zero changed files betweenc100cca8...and the current head. No force-push, rebase, history rewrite, predecessor check transfer, or workflow-gate weakening was used.Every result from all predecessor heads is historical only. The current head must regenerate exact-head evidence.
Test-first lineage and bounded contract
RED head
3887faba96b50f34cff0ad58e5706427d818ec7destablished the missing LLVM runtime-boundary contract. The implementation requires:llvm-19in the digest-pinned trusted coverage image;LLVM_COV=/usr/bin/llvm-cov-19andLLVM_PROFDATA=/usr/bin/llvm-profdata-19bindings;docker run; andThe repair preserves immutable image and cargo-llvm-cov identities, exact-head materialization,
--network=none, credential/Git isolation, native-fuzz separation, reviewer identities, 100% coverage policy, and branch protection. No fallback to unversioned LLVM binaries is permitted.Verification posture
The previously bounded tree completed the Rust coverage toolchain quality workflow, Strix, CodeQL, Python Security, Semgrep, aggregate Security Scan, Secret Scan, SBOM, Scorecard, and OSV successfully, and its review threads were resolved. Those results prove the prior head only.
Current-head quality, security, supply-chain, and semantic-review evidence must all regenerate. Pending, queued, skipped, cancelled, stale, predecessor-head, local-only, author-only, status-only, synthetic, or model-only evidence is not acceptance.
Merge gate
Merge or auto-merge only after the unchanged current head has terminal-success required gates, zero valid unresolved findings, a qualifying current-head semantic verdict, the independent non-author formal approval required by live rules, a compatible live base, and ordinary expected-head merge authority. No admin bypass, self-approval, synthetic approval, protection weakening, or predecessor evidence transfer is requested.
