fix: caret-parity bug in audit tool; correct future-dated backlog entries

[mixmansoundude]

Summary

• tools/audit_console_messages.py's redirect/separator detection only checked one caret back, so cmd.exe's real parity rule (^^& is a literal caret followed by an ACTIVE separator, not an escaped one) was inverted -- a doubled-caret separator was wrongly treated as escaped, letting a later chained command's redirect wrongly drop the preceding call :log record. Replaced the single-lookbehind regexes (REDIRECT_RE, SEGMENT_END_RE) with an explicit backward caret-count scan (_is_caret_escaped).
• Fixed four 2026-08-01 dates that should read 2026-07-31 (today) in CLAUDE.md and docs/open-questions.md.
• Removed docs/open-questions.md's already-resolved cascade-consent paragraph, which contradicted the file's own "only currently-open items" scope (the decision is already recorded in CLAUDE.md's Known Findings and docs/agent-interconnect.md).

This is a follow-up to #406 (merged) -- that PR's own CI was still running when this fix landed, so it never made it into the squash-merge; re-based onto the now-merged main and opened fresh per the branch-restart protocol.

Test plan

• python -m pytest tests/test_audit_console_messages.py -q -- 21 passed (18 pre-existing + 3 new: ^^&/^^| active-separator cases, ^& escaped contrast case)
• tools/run_sanity_sweep.sh (compileall, pyflakes, delimiter check, markdownlint, yamllint, actionlint, ASCII sweep, PowerShell AST parse sweep, full pytest) -- all green, 458 passed / 2 skipped

📝 Walkthrough

Summary by CodeRabbit

• Bug Fixes

  • Improved console message auditing for command separators and redirects, including complex caret-escape scenarios.
  • More accurately distinguishes escaped separators from active command delimiters.

• Tests

  • Added regression coverage for caret-parity behavior in batch command extraction.

• Documentation

  • Corrected documented dates and streamlined open-question formatting.
  • Added guidance describing review expectations and documentation requirements for tooling.

Walkthrough

The audit tool now applies cmd.exe caret-parity rules when it detects redirects and command separators. Tests cover doubled and single caret escapes. Documentation updates dates, a cross-reference, and tool review classifications.

Changes

Console parsing

Layer / File(s)	Summary
Parity-aware command parsing tools/audit_console_messages.py	Shared helpers detect unescaped redirects and command segments. echo and call :log extraction use the new logic.
Caret-parity regression coverage tests/test_audit_console_messages.py	Tests cover doubled-caret separators and single caret-escaped redirects.

Tools review documentation

Layer / File(s)	Summary
Tools review classification tools/README.md	The documentation classifies CI-integrated, embedded-payload, required, and manual-only tools.

Documentation corrections

Layer / File(s)	Summary
Recorded date and reference updates CLAUDE.md, docs/open-questions.md	Four documented dates changed from 2026-08-01 to 2026-07-31. The cascade-consent reference no longer uses the former item number.

Estimated code review effort: 3 (Moderate) | ~15 minutes

Addressed the outside-diff finding too (CLAUDE.md line 956's stale "closes docs/open-questions.md item 1" reference, now that #406 removed the resolved question and item 1 refers to something else): switched to descriptive wording ("closes the former cascade-consent question in docs/open-questions.md") per the suggested fix. Pushed as 4df04b5 along with the two inline findings.
