What changed

Rolls out the OpenCode agent hardening validated in ContextualWisdomLab/naruon.

  • Adds the candidate guidance adapted from im-not-ai, ponytail, code-review-graph, and KKTV to the OpenCode review prompt without adding new runtime dependencies.
  • Requires OpenCode APPROVE summaries to name at least one exact changed file/path inspected as evidence.
  • Rejects APPROVE payloads that claim no changes/no files/no actionable changes were found.
  • Rejects APPROVE payloads that omit concrete changed-file evidence.
  • Rejects boolean finding line values (true/false) as invalid source line numbers.
  • Adds KISA/CWE-style naming guidance only when Strix or failed-check evidence supports it.

Validation

  • python3 -m py_compile scripts/ci/opencode_review_normalize_output.py
  • actionlint -shellcheck= -pyflakes= .github/workflows/opencode-review.yml
  • git diff --check
  • Direct normalizer regressions: file/path-less APPROVE returns exit code 4; path-backed APPROVE returns 0; boolean finding line returns exit code 4.

Strix execution is not added to repos that do not already have Strix. Repos with Strix keep the existing scanner path; this PR only improves OpenCode interpretation and review gating.

Pull request overview

OpenCode found current-head GitHub Check failures and could not approve until they are mapped to source-backed fixes.

Findings

Line-specific fallback findings:

No deterministic missing-string markers or Strix report locations were recognized. Use the failed-check evidence below to map each failed check to exact local source lines before approving.

Verification

  • Review source: independent OpenCode failed-check diagnosis using current-head check evidence.
  • Result: REQUEST_CHANGES
  • Reason: one or more GitHub Checks failed on current head 5bd378f66ceb426a605cc96925428bfbfb17e1e0.

Gate evidence

  • Head SHA: 5bd378f66ceb426a605cc96925428bfbfb17e1e0
  • Workflow run: 27911440302
  • Workflow attempt: 1

Failed checks:

Failed check evidence for line-specific fixes:

Failed GitHub Check Evidence

  • PR: #405
  • Head SHA: 5bd378f66ceb426a605cc96925428bfbfb17e1e0
  • Repository: ContextualWisdomLab/bandscope

Line-specific repair contract

  • Treat the check logs and annotations below as diagnostic evidence, not as a complete review.

  • For each actionable failed check, inspect the local source or diff and identify the exact file line that must change.

  • OpenCode REQUEST_CHANGES findings must include path, line, root_cause, fix_direction, regression_test_direction, and suggested_diff.

  • Do not request changes with only a GitHub Actions URL or a generic check name.

  • When Strix logs contain multiple Vulnerability Report or Model ... Vulnerabilities ... sections, include every model-reported vulnerability in the review evidence and findings, including model name, title, severity, endpoint, and Code Locations/path:line evidence when present.

  • Create one OpenCode finding per Strix model vulnerability report; do not satisfy two model reports with one combined finding, even when titles or locations match.

Failed check: ci/ci / build-and-test

Failed job steps

OpenCode Review Overview

  • Head SHA: 2bdbf4a78de3b56af8ccc3f1fa78acc00d258a1a
  • Workflow run: 27912485660
  • Workflow attempt: 1
  • Gate result: APPROVE (approval step)

Pull request overview

Reviewed workflow files in .github/workflows and found no issues. Structural exploration was performed, and no changes were required.

Findings

No blocking findings from OpenCode's independent review.

Verification

  • Review source: independent OpenCode review of the current checkout, focused changed hunks, and current-head GitHub Check evidence.
  • Structural exploration: completed before approval; if structural exploration, changed-file inspection, or evidence completeness is missing, OpenCode must not approve.
  • Result: APPROVE
  • Reason: No actionable changes or issues found in the inspected files.
