What

Comment-only pass (via the /add-comment skill) over agentic/harness_optimizer/, the newest agentic submodule (merged in the last few days via PR #515, "Deep Agents harness phases 6-9"). Three WHY-comments added:

  • agentic/harness_optimizer/core.pyRunReport.has_critical_governance_finding: flags that this property's "critical:" string match is coupled by convention (not by type) to GovernanceFinding.as_gate_string()'s serialization format in governance.py.
  • agentic/harness_optimizer/runners/github_coding_runner.pyFixtureCase.__post_init__: explains the discarded-return-value call to _safe_child(...), which runs purely for its path-escape-validation side effect.
  • agentic/harness_optimizer/runners/github_coding_runner.pyGitHubCodingRunner._overlay_candidate: explains why the current.rglob("*") rescan exists as defense-in-depth against a file landing in current/ outside the tool-mediated write path.

No other lines in agentic/ needed comments — the rest of deepagent_github/ and harness_optimizer/ (and the surrounding agentic/ package) already carries dense WHY-comments at CLAUDE.md's documented density; this pass avoided padding already-explained code.

Why

Readability for newcomers to the newest, most architecturally dense part of the agentic layer (governance gates for the harness-optimizer's candidate-acceptance pipeline). CyClaw is in feature freeze (CLAUDE.md §1); comment-only changes are explicitly in scope as polish.

Risk to monitor

None expected — this is a zero-behavior-change diff (verified below). Watch for: none: comments do not affect runtime, and the two touched functions' surrounding logic is unchanged.

Verification performed:

  • git diff --stat: insertions only, no deletions, no non-comment lines touched
  • ast.parse() on both files: syntax valid
  • ruff check --select E,F,I,B,C4,UP,S: clean
  • python3 .claude/skills/invariant-guard/check_invariants.py: 27/27 passed (all six invariants + supporting guards hold)
  • Full pytest suite not run — this sandbox has no Python deps installed (a fresh clone has none per CLAUDE.md §4) and installing the full stack (torch, chromadb, etc.) was out of scope for a comment-only, timeboxed pass. Given the diff touches only comment lines with zero behavioral change, this is low risk, but a reviewer with a full env may want to run GROK_API_KEY=dummy pytest tests/test_agentic_harness_optimizer.py tests/test_agentic_harness_phase345.py tests/test_agentic_harness_phase679.py -q to confirm.
