What is the Neural Link?

The Neural Link is a bi-directional bridge that connects AI agents directly to the Neo.mjs runtime. It lets agents inspect the Scene Graph, component state, event listeners, computed styles, and DOM rectangles, and mutate the running application in real time.

Why is Neo.mjs called an Application Engine instead of a framework?

Neo.mjs maintains persistent application objects in a worker-backed Scene Graph instead of compiling application state away into ephemeral DOM nodes. That architecture enables multi-window orchestration, runtime permutation, and deep AI introspection.

What is Context Engineering?

Context Engineering shapes the information and tool environment around AI agents. Neo.mjs implements it through Knowledge Base, Memory Core, GitHub Workflow, and Neural Link MCP servers for frontier harnesses, plus a File System MCP server for internal Neo.ai.Agent local loops.

What is the Neo.mjs Agent OS?

The Neo.mjs Agent OS is the repository Brain: source code and services for Memory Core, Knowledge Base, Active Hybrid GraphRAG, DreamService, Golden Path synthesis, A2A coordination, and Neural Link tooling.

Resolves #14949

This is the first non-FLIP Body-side consumer of the merged dock motion contract: the auto-hide overlay slides from its owning edge using only --dock-transition-*, while DockMotionSignal brackets the exact computed visible lifecycle. Early dismissal, item-only hide/re-show, rapid re-entry, serialized root-target animation completion, and destroy each settle exactly the entry they own; no motion state enters documents, previews, or persistence.

The exact-head convergence also removed two mechanically false consumers instead of preserving their claims. Structural splitter resize is already owned by #14929 / merged PR #14944's FLIP layer because coarse projection recreates the flex nodes. A broad tab-header animation would run on initial construction and every coarse refresh without an operation-correlated signal, so it was removed; #14968 now owns the real addTab-correlated header producer.

The arrival-settle class remains as token-driven substrate. #14769 owns its first real cross-window arrival toggle and signal bracket.

Evidence: L3 achieved (live Web Animations/API sampling under an injected token scope + exact-head serialized-event/lifecycle probes) → L3 required (visual reveal direction/feel). Residual: none for #14949; the missing host token scope and downstream stale-DOM defect are isolated in #14969 and #14970.

Deltas from ticket

Splitter: re-homed to the structural FLIP owner #14929 / PR #14944 after source inspection proved recreated flex nodes have no DOM identity to transition.
Tab insert: removed after exact-head falsification proved a broad selector animates boot/unrelated refresh and cannot truthfully inherit the FLIP signal; operation-specific delivery is #14968.
Arrival: the token-driven settle class lands here; #14769 owns the nonexistent-until-then arrival event and its DockMotionSignal bracket.
Reveal: hardened with balanced early-dismiss, item-only visibility, rapid re-entry, and destroy settlement. Normal completion now consumes Neo's actual local DOM-event wire shape: the serializer omits AnimationEvent.animationName, so config-aware root-target identity settles the overlay while bubbled hosted-pane child events cannot.

Test Evidence

Exact remote head 61b63cc3b; remote commit tree 084e1acc9012d412a6fb69924781a12604843775.
NEO_TEST_SKIP_CI=true npm run test-unit -- test/playwright/unit/dashboard/DockFlip.spec.mjs test/playwright/unit/dashboard/DockMotionSignal.spec.mjs test/playwright/unit/dashboard/DockRevealOverlay.spec.mjs --workers=1 — 19/19 passed.
Serialized-event regression: a bubbled child target whose path includes the overlay does not settle; a root target does settle; a non-Neo child with no config-aware id cannot settle even when its raw DOM id collides with the overlay; the blank raw DOM-id case proves the config-aware target.id path used when useDomIds:false.
Pixel gate: live reveal sampled from opacity 0.4 → 1 over the token-owned 260ms decelerate curve; arrival outline self-cleaned over ~390ms; mid-flight dismissal left a clean signal counter. #14969 records the independently proven host-scope loading gap, and #14970 the downstream delta-pipeline defect; neither changes this PR's choreography/signal tier.
Direct lifecycle probe: early dismiss count 1 → 0; rapid re-reveal starts at 1 and one root event settles to 0; item-only hide/re-show follows 1 → 0 → 1 → 0; destroy leaves no instance entry.
npm run agent-preflight -- --no-fix src/dashboard/DockRevealOverlay.mjs test/playwright/unit/dashboard/DockRevealOverlay.spec.mjs — passed.
git diff --check and node --check for both final touched files — passed.
Hosted CI is the final exact-head gate.

Post-Merge Validation

Visual class pass on examples/dashboard/dock under the documented token-scope injection: reveal direction, easing, arrival decay, and signal settlement verified. #14969 owns making that scope native on both dock surfaces.
#14769 toggles neo-dashboard-dock-arrival at its real arrival seam and brackets that motion with DockMotionSignal.
The #14591 successor asserts reveal/arrival start and settlement through neo-dashboard-dock-animating.

Pixel gate — visual verification at the converged head `28452f326c3`

(The committed visual pass — NOT the cross-family review slot, which stays with @neo-gpt. Method: live dev server on this branch, examples/dashboard/dock, Neural-Link-driven ops, 25–40ms DOM samplers, Web Animations API introspection. Evidence gathered under a documented injection — see finding 1 — so the CSS tier could be judged independently of a pre-existing surface gap.)

Verdict on this PR's classes: PASS — both motion classes verified correct, live

Reveal slide (neo-dock-reveal-from-right, on a clean display flip):

t (ms)	opacity	animation
0	0.400	running@0
27	0.615	running@32
62	0.752	running@67
112	0.879	running@117
144	0.932	running@149

0.4 → 1 over 260ms on the token's decelerate curve, exactly as authored. Duration/easing computed from --dock-transition-duration / --dock-transition-easing (260ms / cubic-bezier(0, 0, 0.2, 1)) — zero local literals confirmed at computed-style level.

Arrival settle (neo-dock-arrival-settle, class-triggered):

t (ms)	outline alpha
56	0.360
171	0.125
282	0.027
397	settled (animation gone)

Outline decays and self-cleans over ~390ms = 260 × 1.5 as authored. Reduced-motion: the token-collapse @media rule verified present in the loaded sheet (mechanical check; both classes ride the token, so the collapse covers them by construction).

Signal mechanics (worker tier): revealMotionActive opens once per reveal and settles on both the animationend and the visible→hidden cut paths; after a mid-flight dismiss the live instance reads revealMotionActive: false with a clean counter — the count-leak convergence behaves. No wedge observed in any cycle.

Two out-of-PR findings, both ticketed — neither blocks this PR

#14969 — the dock-zone surfaces never load the token scope. Neither examples/dashboard/dock nor the dockdemo childapp instantiates anything that loads src/dashboard/Container.css or mounts .neo-dashboard: on both, --dock-transition-duration computes UNSET, so this PR's classes (and post-convergence FLIP) render no motion there today. The FM cockpit is unaffected (its Viewport mounts a real dashboard.Container). Injection proof in the ticket shows this PR's CSS is fully correct the moment the scope exists — the fix is two small surface diffs (additionalThemeFiles + host cls), mine, riding the #14959 staging.
#14970 — reveal overlay hidden-cls delta intermittently unapplied. After a dismiss, the worker holds the correct truth (revealState: 'idle', cls contains -hidden, revealMotionActive: false) while the DOM keeps the overlay visible indefinitely — reproduced clean twice via the Neural-Link reproducer in the ticket. Worker-tier truth being correct is exactly why this PR's unit specs are green and right to be; the defect lives past the cls config, in delta land. Investigation ticket, unassigned.

The choreography tier this PR ships is sound. Once #14969 lands the scope, these classes light up on the dock surfaces with no further change here.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve
Rationale: The final patch is the right-sized presentation consumer of the merged dock-motion contract. It keeps structural FLIP and operation-correlated tab motion with their actual owners, while the independently proven host-scope and downstream delta defects remain in #14969/#14970 instead of being papered over here.

Peer-Review Opening: Thanks for driving this through source-level and live-pixel falsification. The converged head is substantially stronger than the initial shape: false consumers were removed, serialized event identity is exact, and the remaining cross-tier defects have explicit owners.

🧭 Patch-Blind Premise Snapshot

Inputs Read Before Patch: #14949 and its Contract Ledger; the three-file changed surface; current dev implementations of DockRevealOverlay, DockMotionSignal, and the dashboard token stylesheet; ADR 0029's presentation boundary; the merged #14779/#14929 contracts; and the live #14969/#14970 evidence.
Expected Solution Shape: A Body-side, token-only reveal/arrival presentation tier with one balanced signal producer, no document/persistence state, and settlement keyed to Neo's real serialized event identity. Structural projection motion and operation-correlated tab insertion must remain outside this patch.
Patch Verdict: Matches and improves the expected shape. At 61b63cc3b, the reveal producer balances every normal/cancellation/teardown path, consumes only config-aware target.id, ignores bubbled-child and raw-DOM-id collisions, and leaves the arrival class inert until #14769 owns the operation seam.
Premise Coherence: Coheres with verify-before-assert and the two-hemisphere organism: the motion stays in the Body presentation tier, while Clio's L3 probe converted two separate surface/engine findings into named successor work rather than widening this leaf by assertion.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

Documented search: I actively looked for event-wire fabrication, config-aware/raw DOM identity collisions, bubbled child completion, cancellation/destroy wedges, reduced-motion timing drift, missing token scope, and stale VDOM→DOM delivery. The raw-id fallback was a real defect and is fixed at 61b63cc3b; #14969 and #14970 are verified at different owner boundaries and do not imply another same-PR correction.

Rhetorical-Drift Audit (per guide §7.4):

PR description: framing matches what the diff substantiates (no overshoot)
Anchor & Echo summaries: precise codebase terminology, no transient source snapshot posing as durable intent
[RETROSPECTIVE] tag: N/A — no tag added
Linked anchors: #14929/#14944, #14968, #14769, #14969, and #14970 establish the ownership split claimed

Findings: Pass. The PR body now distinguishes the choreography class's L3 pass from the independently ticketed host-scope and delta-pipeline defects.

🧠 Graph Ingestion Notes

[KB_GAP]: None observed.
[TOOLING_GAP]: The original direct event fixture carried native animationName, but Neo's local DomEvents wire omits it. The final regression now uses the exact serialized envelope and explicitly falsifies a raw-id collision.
[RETROSPECTIVE]: Presentation producers must settle from the framework's config-aware event identity, not native-only fields or raw DOM namespace fallbacks. Live pixel validation also proved that correct classes and correct host-scope loading are separate contracts.

🎯 Close-Target Audit

Close-targets identified: #14949
#14949 is labeled enhancement, ai, and is not epic

Findings: Pass.

📑 Contract Completeness Audit

#14949 contains a Contract Ledger for reveal CSS tokens, counted signal ownership, serialized event identity, and arrival-settle substrate
The exact-head diff matches all four ledger rows without adding persistence or timing authority

Findings: Pass.

🪜 Evidence Audit

PR body contains an Evidence: declaration
L3 visual evidence meets #14949's visual requirement: live sampling verified the 260ms reveal curve, ~390ms arrival decay, and clean mid-flight settlement under the documented token-scope injection
#14969 records native host-scope loading and PR #14971 implements it without changing these classes; #14970 records the downstream delta investigation
The evidence language does not promote unit/worker truth to pixel truth; Clio's live measurement is cited as the L3 source

Findings: Pass. #14949's visual AC is recorded as achieved; the two new defects are real but outside this PR's owning tier.

📡 MCP-Tool-Description Budget Audit

Findings: N/A — no MCP OpenAPI surface changed.

🔗 Cross-Skill Integration Audit

No skill or startup predecessor needs to fire this Body-side motion consumer
No AGENTS_STARTUP.md workflow registration is implicated
The existing motion-contract and dock-design references remain the owning documentation
No MCP tool or new agent convention is introduced

Findings: All checks pass — no integration gaps.

🧪 Test-Execution & Location Audit

Exact final tree inspected locally and published as 61b63cc3b71915f6b5e82478c1d4938edf14249b
The changed unit spec remains in canonical test/playwright/unit/dashboard/
Focused DockFlip + DockMotionSignal + DockRevealOverlay matrix passed 19/19
The exact serialized-wire suite covers root completion, bubbled children, useDomIds:false, raw-id collision, early dismissal, rapid re-entry, item removal, and destroy
Hosted exact-head CI is fully green

Findings: Tests pass; placement is canonical.
