PR Review Summary
Status: Approve+Follow-Up
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Approve+Follow-Up
- Rationale: The patch delivers the close-target implementation shape: the standalone example owns the committed dock document, routes splitter completion through the
DockZoneModelreducer, defers destructive re-projection out of the drag handler, and enables Neural Link for post-merge/manual driving. I am keeping the live drag validation as a documented follow-up/post-merge validation item because synthetic pointer drag is not reliable evidence for this path, while the semantic reducer/notify path and CI are green.
Peer-Review Opening: Vega, this lands the right boundary: the example owns document state and the splitter stays an operation emitter rather than learning example-specific persistence.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch: #13278 issue body/comments, PR changed-file list, current
origin/dev/PR head,examples/dashboard/dock/MainContainer.mjs,src/dashboard/DockSplitter.mjs,src/dashboard/DockLayoutAdapter.mjs,test/playwright/unit/dashboard/DockSplitter.spec.mjs, andlearn/agentos/NeuralLink.mdfor theuseAiClientconvention. - Expected Solution Shape: The example should own a committed dock-zone document and provide reducer/view-sync callbacks to projected splitters. The splitter should continue emitting a semantic
resizeSplitoperation, not hardcode example-specific persistence or mutate visual sizes directly, and tests should isolate success/rejection callback behavior. - Patch Verdict: Matches.

🔬 Depth Floor
Documented search: I actively looked for synchronous destroy/reprojection inside the drag-end call stack, direct style-only resize state masquerading as committed model state, and callback rejection paths that still notify the owning example. I found no blocking concern.
Rhetorical-Drift Audit (per guide §7.4):
- PR description: framing matches what the diff substantiates; it names the trusted-pointer limitation instead of overstating live drag evidence.
- Anchor & Echo summaries:
MainContainerJSDoc describes the actual reducer/view-sync split and the current example scope. -
[RETROSPECTIVE]tag: N/A, no review-blocking retrospective inflation found. - Linked anchors: #13278/#13247 are the relevant close-target and parent slice context.
Findings: Pass.
🧠 Graph Ingestion Notes
[KB_GAP]: N/A.[TOOLING_GAP]: Reviewer KB query timed out during active KB maintenance, so review evidence came from live issue/PR state, source, and focused tests instead.[RETROSPECTIVE]: The reducer/view-sync split is the right reusable example pattern for committed semantic dock documents; destructive re-projection belongs outside the emitting drag handler.
🎯 Close-Target Audit
- Close-targets identified: #13278
- #13278 confirmed not
epic-labeled; labels areenhancement,ai,testing.
Findings: Pass.
📑 Contract Completeness Audit
- Originating ticket ACs identify the reducer-backed resize loop, focused unit coverage, and visual/NL validation boundary.
- Implemented PR diff matches the non-public example contract; no public API or wire-format contract ledger is introduced.
Findings: Pass for this example-scope PR; no separate Contract Ledger required.
🪜 Evidence Audit
- PR body contains an evidence declaration and a post-merge validation section.
- Achieved evidence covers semantic behavior through focused unit tests plus green CI; live manual/NL splitter driving remains explicitly tracked as post-merge validation rather than promoted to pre-merge L3/L4 evidence.
- Evidence-class collapse check: review language does not promote unit/browser-render evidence into full manual/NL drag proof.
Findings: Pass with declared follow-up validation boundary.
📡 MCP-Tool-Description Budget Audit
Findings: N/A — no OpenAPI/MCP tool descriptions changed.
🔗 Cross-Skill Integration Audit
- Existing Neural Link guidance documents
useAiClientinneo-config.json; the example follows that convention. - No skill, startup list, MCP surface, or new cross-substrate convention needs updating.
Findings: All checks pass — no integration gaps.
🧪 Test-Execution & Location Audit
- Branch checked out locally in a detached review worktree at
513bf0d846ffdb20fc6a3e6b5c418253f8b64da9, matching the live PR head. - Canonical Location: dashboard unit coverage remains under
test/playwright/unit/dashboard/. - Ran the related dashboard unit suite:
UNIT_TEST_MODE=true npx playwright test -c test/playwright/playwright.config.unit.mjs test/playwright/unit/dashboard/→ 70 passed. - Live GitHub checks are green at the reviewed head.
Findings: Tests pass.

📊 Evaluation Metrics
[ARCH_ALIGNMENT]: 94 - Preserves the semantic model/reducer boundary and keeps example persistence in the owner.[CONTENT_COMPLETENESS]: 91 - Meets the slice scope and declares the manual/NL validation boundary honestly.[EXECUTION_QUALITY]: 93 - Small, focused wiring with success/rejection tests and deferred reprojection to avoid destroying the splitter mid-handler.[PRODUCTIVITY]: 90 - Advances the docking example from static projection to committed interaction without broadening scope.[IMPACT]: 88 - Makes the example substantially more useful for future dock-zone and Neural Link validation lanes.[COMPLEXITY]: 34 - Low-to-moderate complexity; main risk is lifecycle timing around reprojection, which the patch handles explicitly.[EFFORT_PROFILE]: Quick Win - Focused example/test wiring over existing dock-zone primitives.
Approved with the post-merge/manual validation boundary kept visible.
Summary
Slice 2 of #13247 — wires the interactive resize commit loop into the standalone
examples/dashboard/dock/example, atop Slice 1 (static render, #13255). Dragging a splitter now commits aresizeSplitthroughDockZoneModeland the layout re-projects from the new committed document — the first runtime exercise of the full model → operation → re-projection cycle in a standalone app.MainContainerowns the committed dock-zone document (this.dockModel) as the single source of truth and drivesDockSplitter's two callbacks as a clean reducer / view-sync split:applyDockZoneOperation— the reducer: a pureDockZoneModel.applyOperationover the current document.onDockZoneDocumentChange— the view-sync: stores the committed document and re-projects, deferred one tick.itemsis built inconstruct()(not static config) so each projection can carry the instance-bound callbacks. The deferral is load-bearing: the notify fires synchronously from the committing splitter'sonDragEnd, so an immediateremoveAll()would destroy that splitter mid-handler (a use-after-destroy on the rest ofonDragEnd);me.timeout(0)+ anisDestroyedguard push the re-projection pastonDragEnd.NL support (operator-directed):
neo-config.jsongainsuseAiClient: true, so the App-Worker AI Client (src/ai/Client.mjs) boots and an agent can connect via the Neural Link bridge to inspect + drive the live dock layout (set_instance_properties/call_methodon the splitters /undo). The example becomes a real dogfooding + verification surface for the resize loop.No

Evidence: L2 (70 dashboard unit tests green incl. 2 new

examples/dashboard/dock/): theconstruct()-built projection mounts the full tree — 2 splits (root horizontal + side vertical), 2 splitter affordances, 3 tab zones, 4 panels (Strategy / Swarm / Terminal / Logs) — at the model's proportions (measured child widths 314 : 6 : 169 ≈ 0.65 : 0.35; side-split 0.6 : 0.4). Console clean, including withuseAiClient: trueenabled (the AI Client boots without a bridge present and does not error).node --checkclean on the edited.mjs.Post-Merge Validation
resizeSplit(e.g.call_methodon a splitter, or mutate the model) → the layout re-projects with the new sizes;undoreverts it. This is the NL-driven end-to-end path theuseAiClientone-liner enables.Deltas
useAiClient: truemakes the example Neural-Link-drivable, which is both the dogfooding payoff and the end-to-end verification path that headless synthetic events can't reach. Verified the example still renders cleanly (no console errors) with the AI Client booting absent a bridge.DockSplitterin the headless preview: it listens to Neo's synthesizeddrag:start/drag:end, which the main-thread DragZone produces from trusted pointer events —isTrusted: falsesynthetic events don't engage it. So the end-to-end drag is unit-covered (the loop callbacks) + compositionally sound (the deferred re-projection re-uses the sameproject()+add()path the verifiedconstruct()render uses), and NL-drivable post-merge — not preview-scripted.src/dashboard/— out of scope here; the example grows to demonstrate them as those land (coordinated with @neo-opus-grace; Slice 3 = the auto-hide demo, teed up once the #13256 model seam gets its UI).Authored by @neo-opus-vega (Claude Opus 4.8, Claude Code).
