Resolves #15056

The dock example's Perspectives toolbar rendered at 368.5px on a 720px viewport (~51%) with a large empty band above and below its buttons, pushing the dock zones into the bottom half of the screen. Surfaced by the operator during a live review of the #14771 tab-overflow verification.

Root cause: createPerspectiveToolbar() returned the toolbar config with no flex. In the root vbox, the unset toolbar inherited a growing default and split the height ~50/50 with the flex: 1 dock; the toolbar's own hbox align:'center' then vertically centered the buttons inside that over-tall element — the empty band above and below.

Fix: flex: 'none' on the perspective toolbar → it sizes to content and the dock takes the remaining viewport.

AC map

  • Toolbar renders at content height, not a viewport fractionflex: 'none'; verified live 368.5px → 42px.
  • Dock fills the remaining viewport → the flex: 1 dock now owns the freed space.
  • No control/handler regression → config-only change; the toolbar's items, itemDefaults, layout, and handlers are untouched.

Deltas

  • examples/dashboard/dock/MainContainer.mjsflex: 'none' on the perspective toolbar config (one line + a rationale comment).

Test Evidence

Verified via a live runtime probe on the running example: injecting the identical flex reset (.neo-dashboard-dock-perspective-toolbar { flex: 0 0 auto !important }) dropped the toolbar 368.5px → 42px and the dock filled the remainder (before/after screenshots captured). Neo's flex: 'none' config emits the same flex: none on that element.

Checkout note (honest bound): the local dev server on :8080 runs from a different checkout (/Users/Shared/github/neomjs/neo), so a soft reload of the running app does not pick up this branch's source — which is why the source render couldn't be observed locally. The runtime probe is client-side (checkout-independent), so it proves the behavior regardless. A reviewer can confirm the source render by serving this branch (or rebuilding in the serving checkout).

Evidence: L2 (live runtime behavioral probe of the exact fix effect on the real example) — a config-only presentation fix; the measured 368.5px → 42px + corrected layout is the behavior. Residual: source re-render on a checkout that serves this branch (checkout mismatch documented above).

Post-Merge Validation

  • On a checkout that serves this branch, load examples/dashboard/dock and confirm the perspective toolbar is a compact strip with the dock filling the viewport.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The ticket isolates one observable layout defect, and the patch fixes it at the correct flex-participation boundary. It neither hard-codes the measured 42px height nor broadens into the separate visual-polish backlog.

Peer-Review Opening: Nice catch and clean boundary, Grace. The one-line behavior change is small, but the source comment preserves why flex: 'none' is load-bearing beside the growing dock.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #15056; the one-file changed-file list; current dev buildWorkspaceItems() / createPerspectiveToolbar(); the existing dock-model perspective spec; and the root-vbox sibling relationship where the dock alone is assigned flex: 1.
  • Expected Solution Shape: Remove the toolbar from the growing flex pool while leaving the dock as the sole growing child. Do not encode the observed 42px height, change handlers, or move the fix into unrelated dock-model semantics.
  • Patch Verdict: Matches. Exact head f9403c7b5a2949bef219a7daa16ce15cf64760e6 adds only flex: 'none' plus its durable rationale; a direct exact-head probe returned {"toolbarFlex":"none","dockFlex":1,"itemCount":4}.
  • Premise Coherence: N/A — no agent-value surface; this is a scoped example-layout correction whose premise is empirically measured and minimally repaired.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #15056
  • Related Graph Nodes: #13158, #14771, dashboard-dock, perspective-toolbar

🔬 Depth Floor

Documented search: I actively looked for a fixed-pixel-height shortcut, accidental growth on both root-vbox children, and handler/item/config drift; found no concerns.

Rhetorical-Drift Audit: N/A — routine code comment and PR description accurately describe the measured layout defect and the mechanical flex correction.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None.
  • [TOOLING_GAP]: The related DockZoneModel.spec.mjs cannot run in isolation because MainContainer reaches Window.mjs before the spec's setup() establishes Neo.currentWorker; the identical failure reproduces on current dev, so it is not introduced by this PR. CI's full unit job is green.
  • [RETROSPECTIVE]: In a root vbox, intrinsic controls should opt out of growth and the workspace projection should be the explicitly growing child; measuring the symptom helped locate that ownership boundary without hard-coding presentation pixels.

🎯 Close-Target Audit

  • Close-target identified: #15056
  • #15056 is labeled bug + ai, not epic.

Findings: Pass.

🪜 Evidence Audit

  • PR body contains a greppable Evidence: declaration.
  • The author distinguishes the achieved L2 runtime-effect probe from the unobserved source-branch render.
  • The residual source-render check is explicit under Post-Merge Validation.
  • Review language does not promote the CSS injection probe into source-render proof.
  • Exact-head static behavior was independently probed: toolbar flex:'none', sibling dock flex:1, toolbar controls retained.

Findings: Pass with an honest L2 bound; the exact-head probe closes the config contract, while the visual source-render remains the named non-blocking post-merge check.

🧪 Test-Execution & Location Audit

  • Exact head materialized locally from f9403c7b5a2949bef219a7daa16ce15cf64760e6.
  • No test file was added or moved.
  • Related exact-head behavior probe passed.
  • Full CI unit and integration jobs are green.
  • Isolated related-spec failure was reproduced unchanged on dev and classified as pre-existing test-order debt, not PR behavior.

Findings: Pass.
