💡 What: Hoisted static CSP style strings (cssContent, css) and expensive cryptographic SHA-256 hash generation out of the recursive process_dir function, declaring them as top-level private val properties.
🎯 Why: process_dir is called for every single directory traversed. Re-allocating the large CSS string and re-computing the SHA-256 hash dynamically on every recursive call created severe, unnecessary CPU and memory overhead during tree generation.
📊 Impact: Expected to reduce tree generation CPU time and memory allocation significantly on directories with many subdirectories, as string allocation and cryptographic hashing now only happen once at class load time rather than N times.
🔬 Measurement: Verify tests run properly and memory usage/GC pressure is reduced when running html4tree on large directories (e.g. root file systems).

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

  • Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

  • Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

  • Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

  • Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

  • Result: REQUEST_CHANGES

  • Reason: coverage-evidence result was failure, so required test/docstring evidence was not proven for current head aeaa9c29e50cd2734c035133fc881ecdd9ccee32.

Closing as superseded by canonical #363. The same hoisted stylesheet/hash work is implemented there along with exact CSP source-byte matching, independent generated-output verification, APA 7 doctoring, changelog, and fresh current-head CI/JaCoCo/security evidence. Expected-but-unmeasured runtime claims are not retained. No evidence is reused.

Understood. Acknowledging that this work is now obsolete and stopping work on this task.
