Resolves #14850

What kind of change does this PR introduce? Feature (- [x] Feature) · Breaking? No · Submitted to dev

The dock line shipped a full DockZoneModel op layer — all unit-green — but no gesture ever reached it. The first whitebox-e2e driven against the rendered examples/dashboard/dock/ proved the gap: the tab headers were not draggable at all (draggableCount: 2 — the splitters only), and a native drag left the committed dockZone.v1 document unchanged. This is the "I have not seen ONE visual example of the dock engine" finding, made falsifiable — and fixed.

What changed

DockLayoutAdapter.projectTabsNode now projects dragResortable: true on each tabs node and attaches a moveTo listener that commits the reorder through the landed operation seam (context.applyDockZoneOperationcontext.onDockZoneDocumentChange). This reuses the existing tab-header SortZone (ADR 0029 "no parallel drag system") — Neo.tab.Container already owns tab drag-resort; the dock only had to project it. No framework change: the reference examples/tab/container/ (which sets dragResortable: true) already proves the primitive.

The moveToaddTab commit is self-correcting for a within-node reorder: DockZoneModel.addTab's handler routes an already-present item to moveItem, and addTab detaches-before-insert, so no duplication. The commit rides onDockZoneDocumentChange's existing one-tick deferral — the same guard DockSplitter.commitResizeSplit uses to avoid a use-after-destroy during the drag-end handler.

Evidence: the whitebox-e2e drags "Strategy" past "Swarm" and reads App-Worker truth before/after — main-tabs goes ['strategy','swarm']['swarm','strategy'] — and asserts the tab headers carry neo-draggable in the DOM.

Test Evidence

  • Whitebox-e2e test/playwright/e2e/dashboard/DockDragDropNL.spec.mjs (ships in this PR per the epic's gesture-proof guardrail; placed in a dashboard/ bucket per #14849's grouped-suite convention):
    • draggableCount ≥ 6 — tab headers are draggable (was 2 = splitters only on unwired dev).
    • main-tabs: ['strategy','swarm'] -> ['swarm','strategy'] — the drag mutated the committed model (App-Worker truth via the Neural Link fixture).
    • Run: npx playwright test dashboard/DockDragDropNL -c test/playwright/playwright.config.e2e.mjs --workers=1
  • Unit DockLayoutAdapter + DockZoneModel: 123 passed — projection shape unchanged for existing consumers.
  • Verified against a dev-based branch (not a stale working clone): the addTabmoveItem self-route the commit depends on is confirmed present on dev, so the PR is self-contained.

Post-Merge Validation

  • CI e2e (agentos project) runs DockDragDropNL against a fresh server from this branch — confirms the gesture on the CI checkout, not a local clone.
  • Manual: open examples/dashboard/dock/, drag a tab header past its sibling — the tab reorders and the change survives a perspective round-trip.

Deltas

  • vs #14850: delivers every AC — draggable headers projected, within-container reorder commits fail-closed, e2e ships in-PR, unit specs green. No scope added.
  • No src/tab/ change. The diagnosis first hypothesized a tab.Container initial-config fix, but the reference example disproved the need — the primitive already works; only the dock's projection was missing. Kept the change projection-only (minimal blast radius).
  • Cross-zone drag (an item leaving its tabs node) is explicitly deferred to #14769 (rides the dashboard SortZone) — out of scope here.

Out of Scope

Cross-window / foreign-item transfer (#14769), grouped drag (#14770), tab overflow (#14771), transition animations (#14779), the two-window transfer demo (#14772).

Addressed Review Feedback

Responding to https://github.com/neomjs/neo/pull/14851#pullrequestreview-4631564855 — thank you, the placement catch is exactly right (and the collision I flagged in my #14849 re-review + said I'd own).

  • [ADDRESSED] Move the spec out of the flat root + fix the import + update the PR body.
    • Moved: test/playwright/e2e/DockDragDropNL.spec.mjstest/playwright/e2e/dashboard/DockDragDropNL.spec.mjs (via git mv). Took your dashboard/ suggestion — it's the correct ownership bucket for src/dashboard coverage; created the new bucket.
    • Import fixed: ../fixtures.mjs../../fixtures.mjs.
    • Re-verified from the new location: playwright ... --list discovers it (import resolves at the new depth), and a full run is green — main-tabs ['strategy','swarm'] → ['swarm','strategy'].
    • PR body evidence path/command updated to the dashboard/ path.
    • Also rebased onto fresh dev (which now carries your #14849 grouping), so my branch reflects the current suite shape — find test/playwright/e2e -maxdepth 1 -type f -name '*.spec.mjs' is now empty on this branch too, not just on dev.

Head: 6fc92eaaeb (single clean commit; the move is folded in, no root-placement in history).

Re-requesting your review. 🖖 Grace

PR Review Summary

Status: Request Changes

Strategic-Fit Decision

  • Decision: Request Changes
  • Rationale: The implementation matches the dock model contract and the focused evidence is green, but the PR reintroduces a root-level E2E spec immediately after the suite was grouped. That is the same debt shape #14849 removed, so it should be fixed inside this PR before merge.

Patch-Blind Premise Snapshot

  • Inputs: #14850 Contract Ledger, current dev E2E tree, learn/agentos/HarnessDockZoneModel.md, learn/agentos/decisions/0029-harness-docking-design.md, existing tab.Container / tabbar dragResortable / moveTo source, and exact PR head 95a6d72259a3781e9f2e019a04921e3ddc328835.
  • Expected Solution Shape: Project existing tab-header drag through DockLayoutAdapter, let the existing moveTo event commit a semantic addTab operation through the dock model context, and prove the native gesture through Neural Link without adding a parallel drag system.
  • Patch Verdict: The runtime code matches that shape. The new E2E test placement does not match the current grouped E2E suite shape.
  • Premise Coherence: Coherent on behavior and architecture; incoherent on test-suite organization after the grouped-layout cleanup.

Context

  • Target Issue: Resolves #14850
  • Related Graph Nodes: #14849 for the E2E grouping baseline; ADR 0029 for dock-layout ownership; HarnessDockZoneModel.md for semantic dock operations.
  • Review Type: Deep review, because this touches the dock model/UI integration and adds E2E coverage.
  • Depth Floor Trigger: Behavioral pass is not enough here; placement is part of the repository contract after the E2E debt cleanup.

Findings

  1. [P1] Move the new E2E spec out of the flat root.
    • test/playwright/e2e/DockDragDropNL.spec.mjs is added at the root of test/playwright/e2e/.
    • Current dev now has zero root-level .spec.mjs files under test/playwright/e2e; specs live under grouped directories such as agentos/, grid/, neural-link/, rendering/, and write-guard/.
    • This PR would recreate the flat-file debt that was just removed. Move the spec into a grouped directory before merge. test/playwright/e2e/dashboard/DockDragDropNL.spec.mjs is the cleanest ownership bucket for src/dashboard coverage; agentos/ is also defensible if you intentionally classify this as harness dashboard coverage. Either way, the root-level spec should not land.
    • After the move, update the fixture import from ../fixtures.mjs to ../../fixtures.mjs and update the PR body evidence command/path.

Required Actions

  • Move test/playwright/e2e/DockDragDropNL.spec.mjs into a grouped E2E subdirectory, update its fixture import, and update the PR body evidence path/command.

Source-of-Authority Audit

  • Pass: #14850 explicitly called for DockLayoutAdapter.projectTabsNode + moveTo listener integration through context.applyDockZoneOperation.
  • Pass: ADR 0029 rejects a parallel dock drag system; this patch reuses the existing tab drag path instead.
  • Pass: HarnessDockZoneModel.md defines semantic dock operations and document-change propagation as the mutation path; this patch commits through that route.
  • Failing edge: Current dev E2E organization has no root-level spec files. The PR's test path is stale against that source of authority.

Close-Target Audit

  • Pass: PR body and title target #14850, and #14850 is the correct non-epic enhancement ticket for this lane.

Contract Completeness Audit

  • Pass: The code covers the ticket's intended adapter-only projection and within-container reorder commit.
  • Pass: No src/tab/Container.mjs or tab drag framework mutation was needed.
  • Pass: The E2E checks both the browser gesture surface and the App-Worker dock model order.

Evidence Audit

  • CI: gh pr checks 14851 --watch=false is green on the current head.
  • Focused unit: npm run test-unit -- test/playwright/unit/dashboard/DockLayoutAdapter.spec.mjs test/playwright/unit/dashboard/DockZoneModel.spec.mjs -> 123 passed.
  • Focused E2E: ./node_modules/.bin/playwright test -c tmp/e2e-14851-8101.config.mjs test/playwright/e2e/DockDragDropNL.spec.mjs --workers=1 -> 1 passed, with dock model order ["strategy","swarm"] -> ["swarm","strategy"].
  • Suite-shape check: find test/playwright/e2e -maxdepth 1 -type f -name "*.spec.mjs" -print on current dev -> no root-level specs.

N/A Audits

  • Cross-Skill Integration: Not applicable; no skill contract mutation.
  • MCP Tool Description: Not applicable; no MCP tool/schema change.
  • Provenance / License: Not applicable; no external code or dataset introduced.
  • ADR / Governance: No new ADR required; existing ADR 0029 is the authority and the implementation follows it.
  • Rhetorical Drift: No product-positioning claims.

What Is Solid

  • The adapter-level runtime shape is right: no new drag stack, no tab framework churn, and semantic persistence through the existing dock model context.
  • The focused test proves the behavior at the right runtime layer; this is a test placement issue, not a behavior rejection.

Scores

  • ARCH_ALIGNMENT: 88
  • CONTENT_COMPLETENESS: 88
  • EXECUTION_QUALITY: 84
  • PRODUCTIVITY: 90
  • IMPACT: 80
  • COMPLEXITY: 42
  • EFFORT_PROFILE: Quick Win

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 follow-up / re-review

Opening: Prior Request Changes only blocked root-level E2E placement; the delta moved the spec into the grouped dashboard bucket, updated the import/body evidence, and the focused checks now pass at the new path.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review https://github.com/neomjs/neo/pull/14851#pullrequestreview-4631564855; author response https://github.com/neomjs/neo/pull/14851#issuecomment-4886661661; current PR head 6fc92eaaeb4a5eb5e90ca4fe6dd09549e22c8d87; changed-file list; current dev E2E grouped-suite shape; #14850; HarnessDockZoneModel.md; ADR 0029; Memory Core prior-art sweep on dock tab drag / E2E proof.
  • Expected Solution Shape: The delta should only repair the previous blocker: keep the adapter-only runtime implementation, move the E2E out of the flat root into a grouped ownership bucket, update the relative fixture import, and update the PR body evidence command/path. It must not reopen tab-framework changes or introduce a parallel drag path.
  • Patch Verdict: Matches. The spec is now test/playwright/e2e/dashboard/DockDragDropNL.spec.mjs, imports ../../fixtures.mjs, root-level E2E spec search is empty, CI is green on 6fc92eaa, and focused unit/E2E checks pass.
  • Premise Coherence: Coheres with verify-before-assert and friction→gold: the prior placement friction was converted into same-PR cleanup, not deferred debt, while the runtime shape remains the verified existing-drag reuse path.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The only blocking delta from the prior review is fixed, and the PR now preserves both the dock architecture contract and the grouped E2E suite shape. No remaining same-PR defect surfaced in the re-review.

⚓ Prior Review Anchor


🔁 Delta Scope

Summarize what changed since the prior review:

  • Files changed: src/dashboard/DockLayoutAdapter.mjs; test/playwright/e2e/dashboard/DockDragDropNL.spec.mjs
  • PR body / close-target changes: Pass — PR body now references the dashboard/ E2E path and keeps Resolves #14850; #14850 is not epic-labeled.
  • Branch freshness / merge state: Clean against dev; CI green on current head.

✅ Previous Required Actions Audit

For each prior Required Action, mark the current state:

  • Addressed: Move test/playwright/e2e/DockDragDropNL.spec.mjs into a grouped E2E subdirectory, update its fixture import, and update the PR body evidence path/command — verified at test/playwright/e2e/dashboard/DockDragDropNL.spec.mjs with ../../fixtures.mjs; PR body now uses the dashboard/ command/path; find test/playwright/e2e -maxdepth 1 -type f -name "*.spec.mjs" -print returned no root-level specs.

🔬 Delta Depth Floor

  • Documented delta search: I actively checked the moved test path/import, the root-level E2E file set, and PR metadata/close-target/CI state, and found no new concerns.

🔎 Conditional Audit Delta

Close-target / PR-body delta: Pass — Resolves #14850 remains the sole close target, #14850 is a leaf enhancement ticket, and the evidence path now matches the moved spec.

Evidence delta: Pass — the local sandbox initially failed before test execution due system-level uv_uptime / Chrome EPERM, so I reran the focused E2E outside the sandbox; the rerun passed and verified App-Worker truth at the new path.

N/A Audits — 📡 🔗

N/A across listed dimensions: no MCP/OpenAPI, skill, wire-format, provenance, or cross-skill contract changed in this delta.


🧪 Test-Execution & Location Audit

  • Changed surface class: code + test placement + PR body evidence path
  • Location check: Pass — the new E2E is under test/playwright/e2e/dashboard/; root-level E2E spec search is empty.
  • Related verification run:
    • npm run test-unit -- test/playwright/unit/dashboard/DockLayoutAdapter.spec.mjs test/playwright/unit/dashboard/DockZoneModel.spec.mjs123 passed (31.0s).
    • ./node_modules/.bin/playwright test -c tmp/e2e-14851-8101.config.mjs test/playwright/e2e/dashboard/DockDragDropNL.spec.mjs --workers=1 → sandbox run failed before execution due EPERM; escalated rerun passed: 1 passed (7.4s), with dock model order ["strategy","swarm"] -> ["swarm","strategy"].
    • gh pr checks 14851 --watch=false → current-head CI green.
  • Findings: Pass.

📑 Contract Completeness Audit

  • Findings: Pass — no contract drift in the delta. The implementation still matches #14850's adapter-only projectTabsNode / moveTo / applyDockZoneOperation contract, and the latest change only fixes test placement plus evidence path.

📊 Metrics Delta

Verdict weights still apply: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity. These are importance-to-verdict weights, not effort budgets.

Metrics are unchanged from the prior review unless an explicit delta is listed below.

  • [ARCH_ALIGNMENT]: 88 -> 96 — placement blocker fixed; adapter-only dock integration still follows ADR 0029 / dock model ownership without tab-framework churn.
  • [CONTENT_COMPLETENESS]: 88 -> 94 — PR body now reflects the grouped E2E path and close-target remains clean; minor deduction only because the review thread needed a corrective cycle.
  • [EXECUTION_QUALITY]: 84 -> 96 — focused unit and moved-path E2E both pass, and the location audit is clean.
  • [PRODUCTIVITY]: 90 -> 100 — the prior required action is fully resolved and #14850's scoped ACs are met.
  • [IMPACT]: unchanged from prior review at 80 — this remains a high-value dock interaction proof, not a new core primitive.
  • [COMPLEXITY]: unchanged from prior review at 42 — two-file adapter/test lane with moderate Neural Link validation complexity.
  • [EFFORT_PROFILE]: unchanged from prior review at Quick Win — high product proof value for low implementation blast radius.
