What

Write the canonical estate secret-scanner caller to .github/workflows/secret-scanner.yml so this repo emits scan / gitleaks, the context the estate Secret-Scan-Floor ruleset (D243/D244) requires. The previous inline scanner jobs emitted bare contexts (e.g. gitleaks) that cannot satisfy the floor; the reusable deliberately drops TruffleHog as redundant with gitleaks.

Job key scan; reusable hyperpolymath/standards/.github/workflows/secret-scanner-reusable.yml@74d2f66f575246cf6e313ae7775f44df6e097ff2; push trigger on main. actionlint clean (previous file findings: 1). Commit via GraphQL createCommitOnBranch (GitHub-signed, valid: true).

Deferred red checks

Secret-Scan-Floor (D243/D244) requires the context `scan / gitleaks` estate-wide. The previous inline scanner jobs emitted bare contexts (e.g. `gitleaks`) that cannot satisfy the floor; the reusable deliberately drops TruffleHog as redundant with gitleaks. Write the canonical caller: job key `scan`, reusable pinned to standards@74d2f66, push trigger on the default branch `main`.

actionlint: new file clean (findings in previous file: 1).

📝 Summary

Summary by CodeRabbit

  • Chores
    • Updated the automated secret-scanning checks used for pull requests and changes to the main branch. These checks now use a shared scanning workflow; the previous local scanning steps and conditional Rust-secret check have been removed. There are no changes to user-facing features or functionality.

Walkthrough

The secret-scanner workflow now calls a pinned reusable workflow and passes inherited secrets. It grants contents: read and retains pull-request and main-push triggers with per-ref cancellation. The local TruffleHog and conditional Rust scan jobs have been removed.

Changes

Secret scanning

Layer / File(s) Summary
Delegate scanning to the reusable workflow
.github/workflows/secret-scanner.yml
The workflow calls the pinned reusable scanner and passes inherited secrets. It grants contents: read, retains its triggers and per-ref cancellation, and removes the local scanning jobs and steps.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 3c427

The secret scanner workflow forwards every repository secret to a reusable workflow that does not appear to need any. Removing secrets: inherit is a small change that reduces exposure; otherwise the PR is low risk.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 3c427

The new scanner unnecessarily inherits all eligible caller secrets. Its fixed revision, read-only token permissions, and lack of explicit inherited-secret use limit the demonstrated risk; credential theft was not established.

Retained concerns

  • Low · security · observed: The caller newly delegates every eligible caller secret to an external reusable workflow even though its pinned executable implementation contains no inherited-secret references. The stated Gitleaks token dependency exists only in obsolete comments. This unnecessarily broadens credential authority across the repository boundary; no credential theft or additional write authority was established.
Security review details

Security Blast Radius

  • inferred — The credential-delegation scope is the secrets eligible for this caller's runs, potentially including repository and organization credentials with authority beyond repository contents. Their inventory and privileges are unknown. This single caller change does not establish exposure across other estate repositories.

Security Findings and Attack Paths

  • observed — The retained misconfiguration concerns unnecessary secret inheritance. The exact callee directly invokes Gitleaks and contains no executable inherited-secret references. Source inspection establishes over-delegation, but not an attacker-controlled path that extracts those credentials.

Trust Boundaries and Controls

  • observed — The new trust boundary delegates execution and eligible secrets to hyperpolymath/standards. Immutable revisions, checksum verification, read-only token grants, and data-only repository scanning are meaningful counterevidence against a broad authority-escalation claim.

Resilience and Maintainability Implications

  • inferred — Retained per-ref cancellation and read-only hosted-runner scans limit interruption and rerun recovery to transient scan work rather than deployment or persistent-state rollback. Cancellation is not evidence that the required check passed; enforcement remains dependent on the unverified ruleset.

Hardening Proposals

  • proposed — Remove broad secret inheritance from this credential-independent scanner, or explicitly pass only credentials required by a future implementation. Validate the intended required-check behavior without relying on the obsolete token-dependency comment.

The reusable at standards@74d2f66 references no secrets: gitleaks runs as a checksum-verified binary, not gitleaks-action, so `secrets: inherit` only forwarded every repository and organisation secret to it (CWE-250, flagged by CodeRabbit and Hypatia WH008). The earlier comment calling it REQUIRED was copied from the reusable's own stale header note and is corrected here.
