Support Markdown variants for follow-up headings

[wwind123]

Summary

• Share conservative follow-up heading regex construction across same-PR, future, and legacy sections
• Accept full-heading bold markers and a single trailing colon or period for known follow-up headings
• Add regression coverage for bolded headings, period headings, and unrelated bold heading termination

Tests

• python3 -m pytest tests/test_agent_loop.py -k followups
• python3 -m pytest

Closes #80

[wwind123]

Implemented issue #80 and opened PR #81:

#81

Changed protocol.py to recognize approved follow-up headings with full-heading bold markers and a single trailing : or ., while keeping matching limited to the known section names. Added regression tests for bolded headings, period headings, bold-plus-punctuation variants, and unrelated bold heading termination.

Tests passed:
python3 -m pytest tests/test_agent_loop.py -k followups
python3 -m pytest

Review: Support Markdown variants for follow-up headings (#81)

The implementation cleanly addresses issue #80. Here's my analysis:

Regex correctness

The _followup_heading_re helper generates a three-way alternation for each known heading title:

1. {title}[:.]? — plain text with optional trailing : or .
2. \*\*{title}\*\*[:.]? — bold (**title**) with optional punctuation outside the bold markers
3. \*\*{title}[:.]?\*\* — bold with optional punctuation inside the bold markers

All eight meaningful variants are covered: plain (no punct, :, .), bold-outside-punct (no punct, :, .), and bold-inside-punct (:, .). The overlap on the no-punctuation bold case (matched by both alt 2 and alt 3) is harmless.

The #{{2,6}} in the f-string correctly collapses to the literal #{2,6} in the compiled pattern. The [:.] character class is correct — . loses its special meaning inside [], so it matches a literal period only.

Interaction with ANY_HEADING_RE

ANY_HEADING_RE = re.compile(r"^\s*#{1,6}\s+\S") correctly stops parsing at unrelated bold headings like ### **Notes** because ** starts with \S. The new test test_parse_approved_followups_stops_at_unrelated_bold_heading verifies this boundary condition, which is the key risk area.

Test coverage

The parametrized test covers three representative variant groups (plain bold, bold with mixed punctuation positions, and plain-with-period), and the stop test verifies the parse-termination behavior. This is sufficient coverage for the feature as specified.

Title injection concern

The title parameter is an internal regex fragment, not user-controlled input. No escaping is needed, and the type annotation title: str adequately documents the contract for maintainers.

No blocking issues found.

The changes in PR #81 correctly implement support for Markdown variants in follow-up headings, specifically addressing bolded headings and common punctuation (colons and periods).

Analysis

• Regex Robustness: The _followup_heading_re helper function effectively handles various combinations of bolding and punctuation. It supports both ### **Title**: and ### **Title:**, which are common patterns when LLMs generate Markdown.
• Surgical Implementation: The refactor from static regexes to a helper function reduces duplication and makes the code more maintainable while precisely targeting the requested variants.
• Test Coverage: The new test cases in tests/test_agent_loop.py comprehensively cover the reported scenarios, including different combinations of bolding and punctuation, as well as verifying that unrelated bolded headings correctly stop the follow-up parsing.
• Verification: Verified that all 141 tests pass in the PR branch.

The implementation is clean, well-tested, and directly fulfills the requirements of Issue #80.
