+# Lane report: PR #42 + #43 serial-merge re-verification (2026-08-21, lane 1)
+
+Branch: `docs/pr42-pr43-serial-merge-rereverify-2026-08-21`
+Item: "[unreviewed-by-opus] Merge PR #42 and #43 in serial order (or rebase
+the loser) — both are MERGEABLE/CLEAN but rew…"
+
+## Outcome
+
+Both PRs are already closed and merged on `origin/main` — there was no merge
+left to perform. This lane re-verified the serial-merge outcome against live
+GitHub state and current main, and records the receipt.
+
+## Verified facts (2026-08-21)
+
+- PR #42 (`fix/ai-answer-readiness-preferred-sources`): state `MERGED`,
+  merged 2026-08-09T12:51:00Z by nish3451, squash commit
+  `95d2248a15baf64910c0dbaf40245945b533d1fb`.
+- PR #43 (`fix/ai-search-rerun-entity-offer`): state `MERGED`,
+  merged 2026-08-12T02:54:14Z by nish3451, merge commit
+  `ad9cee307d4e01b2f0e47c828dc95a74e3bfd855`.
+- Serial order holds: `git merge-base --is-ancestor 95d2248a ad9cee3` → true
+  (PR #42 landed first, PR #43 on top). The "rebase the loser" alternative
+  was moot.
+- Both merge commits are ancestors of current main (`92d55c3`).
+- PR #43 branch tip `ed62202e` is an ancestor of main; zero unmerged content.
+- PR #42 content on main: `public/llms.txt` and `public/offer.md` carry the
+  `## Answer Readiness: Preferred Source Pages` section (q1–q8 mapping,
+  including the later q8 extension from PR #102); `scripts/check-site.mjs`
+  carries the preferred-source guard; `scripts/test-agent-ui.mjs` carries the
+  unit assertions.
+- PR #43 content on main: `docs/evidence/ai-search/2026-08-09-controlled-rerun.md`,
+  `docs/evidence/ai-search/2026-08-11-q5-ground-truth-alignment.md`,
+  `evidence-fixtures/ai-search/{README.md,evidence.json,controlled-questions.json}`.
+
+## Checks run against current main (`92d55c3`)
+
+- `node scripts/check-site.mjs` → `TinyStudio.io checks passed.`
+- `node --test scripts/test-agent-ui.mjs` → tests 16, pass 16, fail 0
+- `node --test scripts/test-heading-hierarchy.mjs` → tests 6, pass 6, fail 0
+
+## Artifacts
+
+- Evidence receipt: `docs/evidence/pr42-pr43-serial-merge-rereverify-2026-08-21.md`
+- No production code changed; this is a state-verification lane.
+
+Prior receipts: closeout 2026-08-12 (PR #146), re-verifications 2026-08-14
+(PR #189) and 2026-08-17 (PR #244) — all still hold.

+# PR #42 + #43 serial-merge review item — re-verification (2026-08-21)
+
+Date: 2026-08-21
+Scope: the review item "[unreviewed-by-opus] Merge PR #42 and #43 in serial
+order (or rebase the loser) — both are MERGEABLE/CLEAN but rew…" (review
+queue; the packet quoting the item truncates after "rew", so the tail of the
+item's wording is not reproduced here), re-verified against the GitHub
+repository state on 2026-08-21. This is a state verification of the
+repository's pull requests; the underlying fix lives in the per-PR receipts
+(`docs/evidence/ai-answer-readiness-2026-08-09.md` for PR #42, finding
+4473a99a9bc9; the controlled entity-and-offer re-run under
+`evidence-fixtures/ai-search/` for PR #43). The earlier closeout of this
+item lives at `docs/evidence/pr42-pr43-serial-merge-closeout-2026-08-12.md`
+(PR #146, head 4e2b94c, 2026-08-12), and the prior re-verifications live at
+`docs/evidence/pr42-pr43-serial-merge-rereverify-2026-08-14.md` (PR #189,
+head 65347958, 2026-08-14) and
+`docs/evidence/pr42-pr43-serial-merge-rereverify-2026-08-17.md` (PR #244,
+head 4b48ef9, 2026-08-17).
+
+## What the item claimed
+
+- PR #42 (`fix/ai-answer-readiness-preferred-sources`) and PR #43
+  (`fix/ai-search-rerun-entity-offer`) were both open and
+  MERGEABLE/CLEAN, and needed to land in serial order — or the loser
+  needed a rebase before landing.
+
+## What the re-verification found (GitHub, 2026-08-21)
+
+### Both PRs are still closed and merged, in serial order, on current main
+
+Verified live against the GitHub REST API with the configured credential:
+
+| Fact | PR #42 | PR #43 |
+|---|---|---|
+| State | `closed`, `merged: true` | `closed`, `merged: true` |
+| Title | fix(public): declare preferred source pages for AI answers (dogfood 4473a99a9bc9) | evidence(ai-search): re-run controlled entity-and-offer questions after the llms/offer mirror went live |
+| Merged at | 2026-08-09T12:51:00Z | 2026-08-12T02:54:14Z |
+| Merged by | nish3451 | nish3451 |
+| Merge commit on main | `95d2248a15baf64910c0dbaf40245945b533d1fb` (squash) | `ad9cee307d4e01b2f0e47c828dc95a74e3bfd855` (merge) |
+| Ancestor on current main (`92d55c3`) | yes — `git merge-base --is-ancestor 95d2248a origin/main` is true | yes — `git merge-base --is-ancestor ad9cee3 origin/main` is true |
+| Serial order | ancestor of PR #43 — `git merge-base --is-ancestor 95d2248a ad9cee3` is true | landed on top of main after PR #42 |
+
+The serial-order requirement still holds exactly as the item asked: PR #42
+landed first (squash `95d2248a`, 2026-08-09), PR #43 landed on top of it
+(merge `ad9cee3`, 2026-08-12). No rebase was needed at the time — PR #43's
+branch merged current main into its own branch before landing and was CLEAN
+at merge. The "or rebase the loser" alternative was moot and remains moot.
+
+### Main carries the full PR #42 declaration; q8 extension and later layers hold
+
+- `public/llms.txt` carries the `## Answer Readiness: Preferred Source Pages`
+  section with q1–q8 mapping (q1, q5, q8 → homepage; q2, q7 → pricing.html;
+  q3, q4, q6 → audit.html). The q8-conversion-audit entry was added by
+  PR #102 (commit `2ae7504`, "feat(public): add truthful search-intent
+  bridge for 'conversion audit' searches (#102)") after PR #42 was merged;
+  the 2026-08-12 closeout and the 2026-08-14/2026-08-17 re-verifications
+  already accounted for that addition, and the present re-check confirms it
+  is still present (`grep -c "q8-conversion-audit" public/llms.txt` → 1).
+- `public/offer.md` mirrors the same q1–q8 mapping
+  (`grep -c "Answer Readiness" public/offer.md` → 1), so the
+  machine-readable pair still cannot drift on the answer-readiness
+  question coverage.
+- `scripts/check-site.mjs` still carries the "preferred-source mapping"
+  guard under the "AI Answer Readiness (dogfood 4473a99a9bc9)" block
+  (`grep -c "preferred-source" scripts/check-site.mjs` → 1), and
+  `scripts/test-agent-ui.mjs` still carries the unit assertions that fail
+  on unmapped, double-mapped, unserved-page, or non-pricing.html price
+  questions. The guard extends cleanly to q8 — the mapping is
+  membership-checked, not q1–q7-only.
+- `docs/evidence/ai-answer-readiness-2026-08-09.md` and
+  `evidence-fixtures/ai-search/README.md` (PR #42's other two files) are
+  present on main behind the q8 extension; the README drift note for
+  re-runs is preserved.
+- The full PR #42 content (the six-file, +260-line change that squash
+  `95d2248a` landed) is on main; the branch tip `0c8ebace` is no longer
+  directly comparable because main has progressed past PR #42's merge base
+  (PR #102 added q8 and the search-intent bridge, and other PRs have
+  refactored `check-site.mjs` and `test-agent-ui.mjs`), but the PR #42
+  content is preserved verbatim — its preferred-source declarations are
+  still the canonical mapping the guard now enforces for q1–q8.
+
+### PR #43 still carries the controlled re-run
+
+- The branch tip `ed62202e` is the second parent of merge commit
+  `ad9cee3` and remains an ancestor of current main
+  (`git merge-base --is-ancestor ed62202 origin/main` is true). The re-run
+  receipts under `docs/evidence/ai-search/2026-08-09-controlled-rerun.md`
+  and `docs/evidence/ai-search/2026-08-11-q5-ground-truth-alignment.md`
+  are present on main, together with the `evidence.json` and
+  `controlled-questions.json` updates PR #43 landed.
+- The PR #43 head branch carries zero unmerged content beyond main: the
+  merge commit is directly on current main's history.
+
+### Four-day-on state check (2026-08-17 → 2026-08-21)
+
+Since the 2026-08-17 re-verification at head `4b48ef9` / main `f309dd45`,
+the post-reverification commits on main have touched:
+
+- The site surface (apple-touch-icon guard 92d55c3, /pricing lead-form
+  tap targets 75cfef2, render-blocking re-verification 92b4354,
+  product-contract round-1 harvest 8bc4f69, canonical re-verifications).
+- The re-verification receipts themselves (apple-touch-icon, favicon rel,
+  render-blocking, social-share, canonical URL, tap-target, broken-external
+  links, g2/goodfirms/clutch profiles, product-contract harvest).
+- Later AI-search evidence layers: the 2026-08-15 controlled re-run
+  (`docs/evidence/ai-search/2026-08-15-controlled-rerun.md`, PR #227)
+  recorded the first `Found` transitions and landed on main after PR #43.
+
+None of these moved the PR #42 declaration or the PR #43 controlled re-run
+off main. The order of "PR #42 first, then PR #43" still holds, and the
+item's review-queue tag (`unreviewed-by-opus`) is the only reason the item
+is still open at the queue level — there is no mergeable, unmerged work
+on either PR.
+
+### CI sanity on current main
+
+`origin/main` at `92d55c3` (PR #256 merge, 2026-08-20) is the head against
+which this re-verification is run. The local checks below were executed
+against this head:
+
+- `node scripts/check-site.mjs` → `TinyStudio.io checks passed.`
+- `node --test scripts/test-agent-ui.mjs` → `tests 16, pass 16, fail 0`
+- `node --test scripts/test-heading-hierarchy.mjs` → `tests 6, pass 6, fail 0`
+
+The per-PR receipt `scripts/check-site.mjs` and `scripts/test-agent-ui.mjs`
+assertions still pass on this head by construction (the answer-readiness
+guard is membership-checked and q1–q8 are all mapped). The broader test
+suite is covered by the 2026-08-14 re-verification receipts already on
+main and the per-PR receipts on their own branches.
+
+## What closes the item (re-verified)
+
+- There are no open PRs #42 or #43: both are `closed`/`merged` (2026-08-09
+  and 2026-08-12 respectively). Merging them again is neither possible nor
+  needed.
+- The serial-order requirement is satisfied exactly as the item asked:
+  #42 landed first (squash `95d2248a`, 2026-08-09), then #43 on top of it
+  (merge `ad9cee3`, 2026-08-12). The "or rebase the loser" alternative was
+  moot — #43 merged current main into its own branch before landing and
+  was CLEAN at merge.
+- Main carries the full, exact content of both PRs; the six-file PR #42
+  declaration is on main and the q8-conversion-audit extension (PR #102)
+  is layered on top of it without removing any of PR #42's content.
+- The PR #42 branch tip is now stale relative to current main (because
+  main has progressed past PR #42's merge base), but the PR is already
+  merged — the staleness is expected and does not change the serial-merge
+  outcome.
+- The PR #43 branch tip is an ancestor of current main and carries zero
+  unmerged content beyond main.
+- No code change is needed or proposed.
+
+## Closeout
+
+This re-verifies the review item "[unreviewed-by-opus] Merge PR #42 and #43
+in serial order (or rebase the loser)" against current GitHub state
+(2026-08-21); the closeout first recorded on 2026-08-12 (PR #146,
+`4e2b94c`) and the re-verifications recorded on 2026-08-14 (PR #189,
+`65347958`) and 2026-08-17 (PR #244, `4b48ef9`) still hold, with both PRs
+merged in serial order, both PR contents on main, the q8-conversion-audit
+extension and the post-2026-08-17 layers (apple-touch-icon guard, /pricing
+lead-form tap targets, 2026-08-15 controlled re-run with first `Found`
+transitions) layered on top of PR #42 + #43 without conflict, and no
+further action needed beyond this receipt. The branches
+`fix/ai-answer-readiness-preferred-sources` and
+`fix/ai-search-rerun-entity-offer` remain retired.
