Closes #101

Adds a Secret scan (gitleaks) step to the security-scan job in ci.yml.

• Uses the gitleaks CLI (not gitleaks-action, which needs an org licence). The v8.30.1 linux_x64 tarball is pinned by version and sha256 (from the release's checksums file) and verified with sha256sum -c before extraction, matching how the repo pins trivy and git-secrets.
• Runs gitleaks dir . --config .gitleaks.toml --exit-code 1; any finding fails the job, and ci-success already needs security-scan.
• .gitleaks.toml extends the default rules. The tree has three existing false positives (the pinned git-secrets commit SHA in pre-commit.yml and two test token fixtures). Each allowlist entry matches only its exact literal. An earlier revision also set paths with condition = "AND", which in 8.30.1 skips the whole file and hid a planted token; that is fixed and documented in the config.
• scripts/test-gitleaks-config.sh (also run in CI right after the scan) plants a PAT-shaped string beside each allowlisted fixture and requires the scan to fail, and checks that the repository tree is clean. Mutation probe: restoring the paths + AND config fails 3 of its 7 checks.

actionlint passes on ci.yml. History scanning is out of scope (7 findings in history would need a baseline).

📝 Walkthrough

The change adds Gitleaks secret scanning to the CI security-scan job. It adds a Gitleaks configuration and a script that tests the configured allowlists, token detection, and repository tree.

Changes: Gitleaks CI scan

Layer / File(s)	Summary
Gitleaks configuration and checks .gitleaks.toml, scripts/test-gitleaks-config.sh	The configuration enables default rules and allowlists three exact literals. The script checks that the fixtures are allowed, a real-shaped token is detected, and the repository tree scans clean.
CI scan and changelog .github/workflows/ci.yml, CHANGELOG.md	The security-scan job downloads Gitleaks 8.30.1, verifies its SHA-256 checksum, scans the checkout, and runs the configuration test. The changelog records the CI scan.

Merge Risk: 🔵 Low · up to da106

The CI scan can miss a secret containing an approved fixture value. Anchor the allowlists and add an extended-token test; the remaining risk is narrow.

Full details: Linked Issues check

Explanation

Issue #101 has three coding objectives. The PR adds the pinned Gitleaks CI scan, exact-literal configuration, and configuration self-test. The current .pre-commit-config.yaml scans test files and no longer has the broad _test\\.go$ exclusion. However, the PR does not remove or replace the two dead .gitleaksignore entries. This leaves one acceptance criterion unmet.

Resolution

Remove the two dead internal/secrets/aws_resolver_httptest_test.go entries from .gitleaksignore, or replace them with valid fingerprints for actual example-credential test files in this repository.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 2 functions across 1 files. (3 skipped: 3 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Gate note (claude-cc-libs)

Rebased onto main after the overlapping PRs merged. The only conflict was CHANGELOG.md, resolved by keeping both entries. Excluding CHANGELOG.md, git diff origin/main da10645bda2dd2e85d66c73c1d0112ba6e58b732 is identical to the reviewed 7c2dfbcc69f57226e694ae477fc388d72031c958 diff apart from hunk line numbers. Re-verified on the combined tree: vet and go test -count=1 pass.

Merge gate verdict (claude-cc-libs)

Every gate holds at head 7a05fb3:

• Two independent reviews approve the reviewed head 7a05fb3. The branch was then updated from main, and the PR diff is byte-identical to the reviewed diff (compared mechanically).
• CI is green on 7a05fb3, which is the reviewed change on top of current main.
• 0 unresolved threads; MERGEABLE/CLEAN.

CodeRabbit is waived as a merge gate under the 2026-10-19 decision. Squash-merging.
