Reviewed the complete 12-file diff at latest PR commit 50d98ee45 against accepted issue #8291. No competing open PR addresses this slice.
The implementation matches the accepted architecture: one pure CommonJS boundary now owns credential classification and stripping, the CLI keeps filesystem and YAML handling local, both wrappers resolve to the same generated function identities, and direct source plus package-contract tests replace copied parity implementations. I found no code defect in the current diff.
One required evidence gate remains. This is a security-sensitive cross-package change, so the applicable broad gate cannot remain unchecked with only the statement that npm test exposed unrelated failures. Record the exact command result, failing suites and errors, environment, and whether the same failures reproduce on the trusted base; otherwise obtain a passing current broad run or a maintainer waiver that names the failed gate and follow-up. Required GitHub CI and both automated advisors must also finish before approval.
Also replace “targeted current-head proof is green” with a revision-bound result such as: “CLI and plugin type checks and 60 focused credential and package-boundary tests pass at latest PR commit 50d98ee45.” The no-docs-needed classification is correct because the existing backup/restore guide already owns the unchanged credential-stripping contract.
Security review:
- Secrets and credentials: PASS — the shared implementation preserves stripping and placeholder rules without adding credential exposure.
- Input validation: PASS — configuration shapes, credential names, CLI argument forms, environment lines, and secret patterns retain fail-closed handling.
- Authentication and authorization: PASS — no authentication or authority boundary changes.
- Dependencies and supply chain: PASS — no dependency or downloaded artifact changes; the generated module is covered by a package contract.
- Error handling and logging: PASS — no new error or logging path exposes sensitive input.
- Cryptography and data protection: PASS — no cryptographic change; data-redaction behavior remains centralized and tested.
- Configuration safety: PASS — package-local I/O remains separate and both consumers load one generated boundary.
- Security testing: PASS for the focused diff — adversarial names, tokens, placeholders, nested values, CLI arguments, environment content, type contracts, and packaged identity are covered. The repository broad gate remains outstanding.
- System security: PASS — no process, privilege, network, sandbox, or external-state transition changes.
Do not approve this revision until the broad evidence and required automated gates are complete.

Superseding my immediately prior review after the current CodeRabbit result completed.
A valid credential-redaction defect is present in the shared boundary. In scrubArrayElement, a positional value is stripped after a credential flag only when the value does not begin with -. Therefore an input such as ["--api-key", "--opaque-secret-value"] preserves the credential unchanged. The previous token already has to match a complete credential flag, so a leading hyphen on the following token does not make that value safe.
Replace the positional value whenever the preceding token is a credential flag, except for an explicitly accepted safe placeholder. Add deterministic regression cases for a value beginning with a hyphen, ordinary separated and inline credential values, inline OpenShell placeholders, and sensitive versus ordinary basenames. Remove the randomized type-contract fixture so every run proves the same redaction behavior.
The exported global regular-expression arrays are also now one mutable object graph shared by both consumers. Internal matching resets lastIndex, so I did not find a current exploit through repository callers, but freeze the exported collections or otherwise make the shared mutation contract explicit and tested before treating this as the stable security boundary.
Updated security review:
- Secrets and credentials: FAIL — a credential value beginning with a hyphen bypasses positional flag redaction.
- Input validation: FAIL — token shape is incorrectly used to skip a value whose preceding flag already establishes credential context.
- Authentication and authorization: PASS — no authority boundary changes.
- Dependencies and supply chain: PASS — no dependency or downloaded artifact changes.
- Error handling and logging: PASS — no new diagnostic exposure.
- Cryptography and data protection: FAIL — the shared sanitizer can retain an opaque secret in configuration state.
- Configuration safety: WARNING — exported stateful pattern collections are shared and mutable across both consumers.
- Security testing: FAIL — the bypass, inline forms, sensitive basenames, and deterministic union branches are not covered.
- System security: PASS — no process, privilege, network, or sandbox transition changes.
The earlier broad-test evidence and PR wording blockers also remain. Fix the shared sanitizer and tests, rerun the focused and applicable broad gates, and refresh the independent review for the resulting latest PR commit. Do not approve this revision.

Updated head 87119f4 closes the exact-head review blockers: hyphen-prefixed positional credential values are stripped, exported shared pattern collections are frozen with caller-mutation/lastIndex regression coverage, and inline credential, safe-placeholder, sensitive-basename, and deterministic type-contract cases are covered. Validation on this head: CLI and plugin type checks, 63 focused credential/package-boundary tests, and npm run validate:pr all pass. The signed commit is GitHub Verified. |

Maintainer review — latest PR commit 87119f4f2c
The latest delta resolves the prior security findings. The shared boundary now strips an opaque positional credential value that begins with -, freezes the exported pattern collections, resets matcher state before use, replaces the randomized contract fixture with deterministic assertions, and adds focused CLI-form and basename coverage. The accepted #8291 consolidation scope remains intact, package-local I/O stays separate, and current focused/broad checks plus CodeRabbit and both advisor lanes pass.
One revision-bound explanatory-text blocker remains:
- The PR incorrectly says behavior is unchanged. Both prior implementations preserved an opaque positional credential value beginning with
-; this latest PR commit deliberately fixes that credential-sanitization gap. Existing backup/restore documentation already promises that recognized credential values are stripped, so no public page or guide-variant change is needed. Replace the Docs-not-applicable justification and Documentation Writer Review evidence so they state that the fix brings implementation into line with the existing documented contract, rather than calling it an internal consolidation with no user-visible behavior change.
Use a current no-docs-needed receipt that names the leading-dash fix and the already-accurate owning documentation. I did not approve or merge.

Maintainer review update — implementation passes; body evidence needs correction
I reviewed the complete 13-file diff and the test-only guard-coverage delta at latest PR commit 559ea886a1ca310abbf7a1e6117b43a8e303488a against accepted #8291. The shared boundary preserves existing credential classification, recursive stripping, environment and file sanitization, placeholder handling, no-follow backup I/O, and packaged-module identity. The leading-dash positional-value repair brings behavior into agreement with the existing backup/restore documentation. The documentation writer receipt is current, and all current automated checks are terminal and passing.
Two explanatory-text blockers remain:
- Bind verification evidence to the correct revisions. Both Verification lines call
87119f4f2cthe latest PR commit, but the commit under review is559ea886a. Describe the 63 focused tests andvalidate:pras historical evidence from87119f4f2c, then state that current GitHub checks pass at559ea886aand cover the test-only configuration-value guard delta. - Correct the generated release classification. The CodeRabbit section presents the internal consolidation and existing recursive sanitizer and placeholder behavior as New Features. Remove that section or rewrite it as an internal refactor plus the leading-dash positional credential-stripping bug fix. Do not imply that this PR creates newly supported sanitization surfaces.
Security review: secrets and credentials, input validation, authorization, dependencies, error handling, cryptography and data protection, restrictive configuration, system security, and security testing PASS.
I did not run local validation, approve, or merge.
Superseded by the completed fixes and current evidence at latest PR commit 559ea88: the credential bypass and pattern-mutation findings are fixed, the PR text and documentation receipt are current, and required validation passes.

Reviewed the complete 13-file change at the latest PR commit. The shared boundary preserves one credential-filter implementation for both consumers, fixes leading-dash positional credential stripping, freezes exported pattern collections, preserves accepted placeholders, keeps filesystem and YAML handling local, and has direct source and package-boundary tests.\n\nAll review feedback is resolved, both commits are Verified, the documentation receipt is current, and required checks pass. The shard-5 retry passed; its initial process-liveness fixture failure was unrelated to this diff.\n\nThe second-opinion findings were checked and do not apply: the build order is explicit, the leading-dash behavior is intentionally fail-closed, and the reported regular-expression quantifier did not change.
Superseded by the corrected PR description: verification evidence now names the commit where each command ran, current GitHub checks are bound to the latest PR commit, and the generated release section that overstated the change has been removed.
Summary
Consolidate the CLI and plugin credential-stripping logic behind one generated CommonJS boundary. This removes the two drifting implementations and fixes the shared sanitizer so a positional credential value beginning with
