Integrated security outcome

This PR is the current-main successor for the complete sandbox evidence-redaction repair. It preserves the exact #906 wrapper-redaction ancestor d573d21752e07d3cbbf9845b4b413baf81ecea7c and adds the atomic raw-JSON boundary required by #908.

Exact identity, ancestry, and scope repair

After the previously bounded head 21d150867d630180c8e96b8d8207bb78f5c70ecf, unrelated architecture and trusted-lock-test drift entered this branch. A non-destructive forward commit now points to the exact previously bounded tree. GitHub compare reports zero changed files between 21d15086... and the current head. No force-push, rebase, history rewrite, or predecessor evidence transfer was used.

#906 and every other predecessor-head check, review, approval, or comment remain historical and non-authorizing. Current-head evidence must regenerate.

Fail-first and implemented boundaries

The stack preserves separate fail-first reproductions for:

  • malformed public sh -c, env -S, and env --split-string= quoting that exposed an opaque credential;
  • multiline JSON key/colon/value separation;
  • duplicate sensitive keys;
  • sensitive scalar/container type and shape loss;
  • malformed multiline structural candidates leaking through line-local fallback; and
  • absent byte, depth, token, string, replacement, and cumulative-work limits.

The implementation uses bounded wrapper parsing plus an iterative token/span JSON rewriter. It preserves untouched slices, duplicate-member order/count, escape spelling, layout, scalar categories, container shape, and stable result markers. Unsafe quoting, parser state, or limit exhaustion fails closed.

The bounded tree also:

  • recursively enforces public production docstrings across functions, methods, nested helpers, and classes;
  • avoids repeated malformed-JSON candidate rescans near the maximum input bound;
  • prevents rejected short allowlisted environment values from redacting unrelated cwd and sandbox evidence;
  • fixes test execution roots and runtime margins for bounded subprocess regressions; and
  • keeps prior actionable findings addressed.

Verification posture

The previously bounded tree completed the sandbox-redaction quality workflow, Strix, CodeQL, Python Security, aggregate Security Scan, Semgrep, Secret Scan, OSV, Scorecard, and SBOM successfully. Its focused and full suites reported exact 100% owned statement/branch coverage and complete public documentation; review threads were resolved. Those results prove the prior head only.

The current head must regenerate every applicable exact-head quality, security, supply-chain, and semantic-review result. Pending, queued, skipped, cancelled, absent, stale, predecessor-head, local-only, author-only, status-only, synthetic, or model-only evidence is not acceptance.

Acceptance and rollback

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 and last-push conditions required by live rules, a compatible live base, and ordinary expected-head merge authority. No administrative bypass, self-approval, synthetic approval, or protection weakening is requested.

After protected integration, run synthetic stdout, stderr, timeout, and bounded service-tail acceptance before closing #907/#908. Output-memory and service-file quotas remain separately tracked in #766. Rollback requires a protected reviewed replacement preserving wrapper parsing, atomic layout-preserving JSON redaction, cumulative resource budgets, fail-closed malformed input handling, and exact evidence non-contamination.

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 56 minutes

Limit details: You’ve used all 1 included review currently available under your plan.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🔵 Low · up to 0e70d

The PR changes sandbox redaction to preserve raw JSON layout atomically and adds related validation and documentation; no concrete runtime or security defect is identified, but unrelated trusted-uv test changes and missing assertions for operator-facing workflow prose leave bounded scope and contract-maintenance risks requiring explicit owner follow-up. It is otherwise mergeable with that awareness.

GREEN implementation published at exact head 730274cceece6db95986bf65fc46f7c5a132f467 on unchanged parent #906 18a6d125fead8cb95972fe3e1a97e4cc4163e9d2.

Proof before publication:

  • fail-first boundary on the parent: 5 failed, 1 passed;
  • focused security/wrapper/sandbox selection: 155 passed;
  • owned modules: 1,039/1,039 statements and 416/416 branches;
  • complete repository suite: 1,073 passed + 16 subtests;
  • complete owned production: 7,650/7,650 statements and 3,074/3,074 branches;
  • public callable docstrings: 100%;
  • compilation, diff integrity, and Strix quick gate: passed.

The production path is an iterative token/span parser plus iterative replacement traversal. It preserves untouched slices, escape spelling, duplicate-member order/count, layout, scalar categories, and container shape. Input/depth/token/string/replacement/work bounds fail closed without parser diagnostics. Command-field fallback preserves the original JSON array shape. Issue #766 remains explicitly separate.

Hosted exact-head checks and current source review remain authoritative; this local proof does not promote the Draft or count as approval.

Fresh read-only semantic review requested for exact stacked head 0b8b2a286094d6e52a9160faee678c5b75f1711e against current parent #906 d573d21752e07d3cbbf9845b4b413baf81ecea7c. This non-destructive two-parent merge carries the malformed-wrapper fail-closed repair into the atomic JSON implementation. Local merged-tree evidence: 158 focused passes with 1,044/1,044 statements and 420/420 branches; 1,076 full-suite passes plus 16 subtests; complete owned production 7,655/7,655 statements and 3,078/3,078 branches. No hosted workflow on this non-default-base Draft is treated as passing. Preserve Draft and keep automated judgment separate from independent approval/merge authority.

Review exact current head 21d150867d630180c8e96b8d8207bb78f5c70ecf against independently resolved protected main 6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba.

This head addresses all five actionable CodeRabbit findings from predecessor head 0b8b2a286094d6e52a9160faee678c5b75f1711e: recursive public-docstring inspection, bounded malformed-JSON candidate classification, rejection of contaminating allowed-env values, stable subprocess seams/timeouts, and the associated maintainability corrections. All five threads are resolved on the current tree.

Exact local proof: 1,078 tests plus 16 subtests; 7,665/7,665 statements and 3,080/3,080 branches; public docstrings, compilation, and clean-diff checks all passed. All ten exact-head hosted workflows are terminal-success, including Sandbox Log Redaction Quality, CodeQL, Semgrep, Python Security, Security Scan, Secret Scan, OSV, Scorecard, SBOM, and Strix. CodeRabbit current status is success.

Review raw-layout preservation, malformed nested JSON limits, atomic secret replacement, child-process evidence isolation, environment rejection, and evidence-authority separation. Anchor any source finding to this exact head. Automated judgment is not qualifying human approval, merge authority, or protected-main operational acceptance.

Review exact current head 21d150867d630180c8e96b8d8207bb78f5c70ecf only. All prior CodeRabbit findings are resolved on this head. Validate the bounded wrapper parser and iterative raw-JSON token/span redactor preserve untouched layout, duplicate-member order/count, escape spelling, scalar categories and container shape while fail-closing malformed sensitive structures and every byte/depth/token/string/replacement/cumulative-work limit; confirm the near-input-limit malformed-candidate path is not quadratic. Verify short or unsafe allowed-environment values cannot contaminate cwd/sandbox evidence, public callable docstrings are recursively gated, and command/stdout/stderr/timeout/service-tail evidence uses the same redaction boundary. All ten exact-head hosted quality/security/supply-chain workflows are terminal-success and all inline threads are resolved. Review only; do not mutate, merge, release, or bypass protection.

Exact-current-head review request for 21d150867d630180c8e96b8d8207bb78f5c70ecf over protected main@6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba.

Review the complete 12-file atomic evidence-redaction boundary on this exact head, not the stale head recorded in the PR prose: bounded wrapper grammar; iterative raw-JSON token/span rewriting preserving layout, duplicate members, types and shapes; cumulative byte/depth/token/string/replacement/work budgets; fail-closed malformed sensitive candidates; allowed-environment rejection without contaminating cwd/sandbox evidence; recursively enforced production docstrings; and bounded worst-case runtime. All five current CodeRabbit findings and associated nitpicks are addressed and resolved in 21d1508. Sandbox Log Redaction Quality CI, Strix Changed Path Quality CI, CodeQL PR, Python Security, Security Scan, SAST Semgrep, Secret Scan, OSV-Scanner PR, Scorecard PR, and SBOM Generation are terminal-success.

Keep the exact head unchanged. Do not transfer predecessor review evidence, synthesize author approval, weaken redaction/budget/schema contracts, merge, release, or bypass protection.

Exact-current-head automated and independent review requested for 21d150867d630180c8e96b8d8207bb78f5c70ecf against protected main@6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba.

Fresh evidence: all ten directly observed exact-head workflows are terminal-success and all five predecessor CodeRabbit findings are resolved on this exact head. Review the bounded wrapper parser and iterative token/span JSON rewriter: raw JSON layout, duplicate-member order/count, escape spelling, scalar category, container shape, and stable markers must be preserved; unsafe quoting, malformed parser state, or byte/depth/token/string/replacement/cumulative-work exhaustion must fail closed. The current head also eliminates repeated malformed-candidate rescans, recursively enforces public callable docstrings, prevents rejected short allowlisted values from contaminating cwd/sandbox evidence, and fixes subprocess roots/time margins.

Submit an exact-head verdict without updating the branch, weakening redaction limits, importing predecessor #906/#907/#908 evidence, synthesizing author approval, or bypassing protection.

Pull request overview

OpenCode could not approve from deterministic current-head evidence because GitHub Checks have failed.

Findings

1. HIGH Current-head GitHub Checks - Fix failed required checks before approval

  • Problem: Failed same-head checks remain for b19bbdd2999ff53d0bf6f0a5cb25e200c18a745e.
  • Root cause: The model-unavailable evidence fallback is allowed only when peer GitHub Checks are complete and clean.
  • Fix: Read and fix the failed check logs below, then rerun the current-head checks.
  • Regression test: Keep the model-unavailable fallback gated on an empty failed-check rollup.

Returned to Draft because the exact current tree mixes the integrated sandbox redaction repair with an unrelated trusted-uv materializer branch.

The security slice itself is coherent: bounded wrapper parsing, iterative layout-preserving JSON token/span rewriting, duplicate-key/order/type preservation, fail-closed malformed/limit behavior, and exact stdout/stderr/timeout/service-tail evidence tests. Head b19bbdd2999ff53d0bf6f0a5cb25e200c18a745e additionally changes materialize_base_python_requirements.py and its tests, which do not belong to the redaction trust boundary.

Rebuild from protected main retaining only the redaction/sandbox production files, focused regressions, dedicated 100% quality workflow, bounded doctoring/governance references, and changelog evidence. Preserve materializer work in its authoritative PR, update the stale head/evidence section, then reacquire exact-head security and independent-review approval.

I removed the unrelated trusted-uv production delta by restoring the exact RFC 8259/ECMA-404 redaction tree as a new descendant. The branch still implements bounded wrapper parsing, atomic layout-preserving raw JSON redaction, duplicate-key/order/type preservation, cumulative resource budgets, fail-closed malformed input, and previously repaired CodeRabbit findings; all existing review threads are resolved. Exact-head checks are regenerating; nonterminal evidence is not acceptance. Review read-only; do not mutate source, synthesize approval, weaken redaction/security gates, or merge.

Do not merge this head. Take #1031.

A realistic GitHub Actions job log with ##[group] plus a later pretty-printed password object is fail-closed to a single [REDACTED]. The span finder treats every [ as a JSON array start. The failed parse then scans the whole document for a sensitive key, so the later valid object poisons the entire evidence dump. Operators lose the status line, duplicate-key layout, and every non-secret diagnostic.

#1031 starts a span only after a plausible opener, scores a failed parse only until the next opener, cites RFC 8259 / ECMA-404 / ISO/IEC 21778, and pins the quality-gate operator prose. Focused redaction selection there: 163 passed, 100% owned statement/branch coverage.

Unresolved CodeRabbit prose-contract thread is also closed in #1031. Current-head checks on this SHA are not merge evidence for the leak.

This full-text candidate check is the leak. ##[group]Runner starts a JSON parse at [, the parse fails, then _looks_like_sensitive_json_candidate(text) sees the later "password": and replaces the entire job log.

Score only text[start:next_plausible_opener], and skip [ after # or a letter. Successor: #1031.
