Session Handoff [review-tooling]: Shared Heading Reduction and Line-Suffix Pairing Released as 2.0.1079, Interleaved Sections Next #3185

Next steps, in priority order

1. Read Every Section of a Kind When Sections Alternate in One Wrapper in pr_review.py #3180: read every section of a kind when sections alternate in one wrapper, in pr_review.py. marker_blocks now chains through same-kind bounds only, so suppressed, then previously missed, then suppressed in one region leaves the third section unread. develop had this gap before Read a Section Heading Through One Reduction in pr_review.py #3179. Done looks like: the constructed body in the issue gives two suppressed blocks and one previously-missed block, and no shape in the test file reads differently. The issue sketches a walk over every bound line.
2. Tell a Timed-Out Node Probe From an Engine Disagreement in test_spec_validate #3182: tell a timed-out Node probe from an engine disagreement in test_spec_validate. It flaked once on the Windows unit test job of Pair a Review Findings Entry With Its Thread Past the Line Suffix in pr_review.py #3181, and a re-run passed. Done looks like: a TimeoutExpired no longer fails the suite as a pattern disagreement.
3. Finish the Incidental Count Sweep, Including Counted Section Titles #3169: finish the incidental-count sweep. Carried over, lower priority.
4. pr_review.py Passes a Clean-Verdict Copilot Round Whose Headline Sentence Names a Finding #2567: a clean-verdict round whose headline names a finding. Needs a design decision on reading headline prose before any code, so ask before starting it.

External blockers

None.

Internal dependencies

• Read Every Section of a Kind When Sections Alternate in One Wrapper in pr_review.py #3180 and Tell a Timed-Out Node Probe From an Engine Disagreement in test_spec_validate #3182 are independent of each other and of Finish the Incidental Count Sweep, Including Counted Section Titles #3169.
• pr_review.py Passes a Clean-Verdict Copilot Round Whose Headline Sentence Names a Finding #2567 waits on the maintainer's design call. It is not filed under the decision label, so raise it as a question when it comes up.

State

• Released 2.0.1079 from main at efaeeee2, the merge of promotion Promote the Shared Heading Reduction and the Line-Suffix Pairing to Main #3183. It carried Read a Section Heading Through One Reduction in pr_review.py #3179 and Pair a Review Findings Entry With Its Thread Past the Line Suffix in pr_review.py #3181, and closed Read a Finding Entry Titled With the Suppressed Marker as No Section in pr_review.py #3173, Read a Section Heading Through One Reduction in pr_review.py #3174, and Pair a Review Findings Entry With Its Thread Past the Line Suffix in pr_review.py #3176.
• This machine's Codex and opencode skills snapshot was refreshed from efaeeee2 and reads current. The host-safety kit reports CURRENT.
• The primary checkout is on develop, clean, and fast-forwarded to 1a511c80. No task worktree or feature branch from this round remains, locally or on the remote.
• No other repository was touched.

The parked decision queue

The queue held 0 open issues with the decision label when this was written. Nothing is parked.

What the last round did

• Read a Section Heading Through One Reduction in pr_review.py #3179 reads a heading through one reduced / spaced reduction and one LEADING_COUNT, shared by normal and heading_count. The vetted-but-unread check now compares which summaries the blocks hold. Two same-kind sections in one wrapper are two blocks, and a finding entry opening on a severity badge is never a section heading.
• Pair a Review Findings Entry With Its Thread Past the Line Suffix in pr_review.py #3181 strips a trailing :LINE or :START-END in entry_paths, so Review findings: and Open findings remain: entries pair with their threads.
• Filed Read Every Section of a Kind When Sections Alternate in One Wrapper in pr_review.py #3180 (pre-existing interleaving gap, found by the local review) and Tell a Timed-Out Node Probe From an Engine Disagreement in test_spec_validate #3182 (Windows probe flake).
• Declined one Copilot P1 on Read a Section Heading Through One Reduction in pr_review.py #3179 with a probe. A quoted summary inside a block counts on both sides of the read check, and its suggested heading_of fix would have brought back the bare-line stand-in.

What not to repeat

• Read a Section Heading Through One Reduction in pr_review.py #3174's "Expected" was half wrong. It called two nested previously-missed sections read as one block "the way develop reads them" and treated the check reporting them as the false positive. In fact the block was counted by its first heading alone, so silencing the report would have hidden an undercount. Read an issue's own claim about acceptable current behavior as a hypothesis, and check the count the digest prints.
• Resuming the scan after a section bound reads prose as a section. The first fix for the undercount let a prose line carrying low confidence and a (N) open a second suppressed block. A further block in a region opens only at the bound the previous block ends at.
• The local strict review took three passes on Read a Section Heading Through One Reduction in pr_review.py #3179 again, each fix making the next finding. It converged once each fix was checked against every shape the test file carries, not only the one it targeted.

New learnings

• None beyond the issues filed. The non-convergence is already local-strict-review's rationale for its edit budget.
