PR Review Summary

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Approve over Request-Changes/Drop because the section is accurate to the shipped reality and correctly bounded — it marks exactly one landed slice (#12708) and keeps the larger View-owned multi-body architecture (#9491/#9872/#9492) open, with an explicit non-over-claim instruction for the final prose. Docs-only, CI green; no defect blocks merge.

Peer-Review Opening: Nicely scoped — the landed-vs-open split is precise and the explicit "do not imply the View-owned multi-body grid architecture has fully shipped" line is exactly the discipline this public artifact needs. The Mermaid cut-line is a clean touch.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: close-target #12698; the diff; the ACTUAL merge-state of #12708 (verified MERGED, commit b3ee96c89) + its content; the open state of #9491/#9872/#9492; the #9492 design-lock comment; and my own #12708 implementation (I authored it, so I know the shipped contract first-hand).
• Expected Solution Shape: the Body/Grid note should mark #12708 (SortZone region-body resolution) as the one landed slice + #9491/#9872/#9492 as open boundaries, with NO claim that the View-owned multi-body grid architecture has shipped.
• Patch Verdict: Matches. The diff describes #12708 precisely as implemented (grid via owner.gridContainer, body via toolbar layoutLock → bodyStart/body/bodyEnd, mirrors grid.header.Toolbar, unit coverage for the body-resolution contract) and accurately scopes #9491/#9872/#9492 as open, with the explicit no-over-claim line. Evidence: I cross-checked the prose against my merged #12708 diff and the live open tickets.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #12698
• Related Graph Nodes: Related #12696 (v13 release epic); Refs #12708 / #12707 / #9491 / #9872 / #9492.

🔬 Depth Floor

Challenge: The one phrase to watch as this section becomes final prose: "gives locked-start and locked-end column drags the correct region body." That is accurate for the body-resolution contract #12708 ships — but a fully-correct locked-region resort also needs the global↔region-local column-index remap, which is still open under #9491. The current draft scopes #9491 correctly ("index remapping" open), so this is non-blocking — just keep the body-resolution-vs-index-remap distinction crisp in the final prose so a reader doesn't infer locked-region drag-reorder is end-to-end shipped.

I also actively verified: (1) the cited #12708 description matches the merged implementation (it does); (2) the #9492 design-lock link resolves to the canonical design-lock comment (it does); (3) no open ticket is mischaracterized as landed (none is).

Rhetorical-Drift Audit (per guide §7.4):

• PR description: framing matches what the diff substantiates — #12708 framed as the one landed slice, not as the whole architecture.
• Anchor & Echo summaries: N/A — no JSDoc/API surface; this is release-note prose.
• [RETROSPECTIVE] tag: N/A.
• Linked anchors: the #9492 design-lock link + the #12708/#12707 references actually establish the claimed landed/open split (verified, not borrowed authority).

Findings: Pass. The prose tracks mechanical reality; the explicit "without implying the View-owned multi-body grid architecture has fully shipped" line is the correct guard against KB/SEO ingestion drift. The Mermaid sequence (drag → SortZone resolves grid → layoutLock selects region body → #12708 landed → #9491 → #9872 → #9492) is accurate.

🧠 Graph Ingestion Notes

• [KB_GAP]: N/A.
• [TOOLING_GAP]: N/A.
• [RETROSPECTIVE]: Good model for release-note discipline mid-release: when one slice of a multi-PR architecture lands, describe THAT slice as shipped evidence with the named PR, and keep the rest as explicit open boundaries with a final-prose-replacement checklist item — rather than either over-claiming the whole or leaving a stale design-only gate.

N/A Audits — 📑 🪜 📡 🧪 🔗

N/A across listed dimensions: docs-only release-note edit — no public/consumed code contract (Contract), no runtime-AC beyond L1 docs-source verification (Evidence; PR declares L1 → L1 required), no OpenAPI surface (MCP), no test files or code paths (Test-Execution — no tests required for a docs change), and no new skill/convention/MCP surface (Cross-Skill).

🎯 Close-Target Audit

• Close-targets identified: #12698 (via Resolves #12698).
• For each #N: confirmed not epic-labeled — #12698 is documentation/enhancement/ai (leaf). The v13 epic #12696 is correctly referenced as Related: (non-closing), and #12708/#12707/#9491/#9872/#9492 as Refs (non-closing).

Findings: Pass. Single newline-isolated Resolves #12698; no epic close-target; CI lint-pr-body green.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 100 — follows the v12.0/v12.1 narrative-hero release-note shape + the §0 cut-line discipline; I considered over-claim, framework-abandonment framing, and a stale design-only ceiling, and confirmed none apply (it bridges Brain-on-Body and scopes open work explicitly).
• [CONTENT_COMPLETENESS]: 100 — landed slice, open boundaries, design-lock link, Mermaid diagram, representative anchor, and the Release-Cut Checklist update are all present; I checked for a missing open-scope, a missing anchor, and a missing checklist update and found none.
• [EXECUTION_QUALITY]: 95 — 5 deducted because the "gives locked-start/end column drags the correct region body" clause sits one step from the still-open #9491 index-remap and could read as more-shipped-than-it-is in the final prose; otherwise CI is green (5/5) and the prose matches the merged #12708 + live tickets (verified).
• [PRODUCTIVITY]: 100 — achieves the #12698 goal (Body/Grid cut-line reflecting #12708-landed) cleanly; I confirmed the section, diagram, anchor, and checklist all advance that goal with nothing deferred.
• [IMPACT]: 60 — substantive public release-artifact section (the grid cut-line for the v13 narrative); meaningful for the release + KB/SEO ingestion, but a docs section, not framework-core.
• [COMPLEXITY]: 25 — Low: docs-only edit within the existing release-note structure plus a small Mermaid diagram; no code paths, no cross-substrate integration.
• [EFFORT_PROFILE]: Quick Win — high ROI (accurate public cut-line that prevents over-claim drift) at low complexity (prose + diagram).

Clean, accurate, well-bounded. Approving; the cross-family gate is satisfied. The non-blocking phrasing watch-item is yours to fold in (or not) when this section becomes final prose after the remaining grid PRs land.
