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 #15574 Related: #15254 Related: #15028 Related: #14646 Related: https://github.com/orgs/neomjs/discussions/15570

Restores the Fleet mission-control recording to the settled time-neutral product contract. The walkthrough's module contract now calls the unscripted capability the fleet-start cascade, and its public closing caption uses the shipped Start fleet label instead of the stale morning-only framing.

Evidence: L1 (exact source anchors plus a focused runtime-script witness that failed against the old recorded caption and passed after repair) → L1 required (a deterministic screenplay-copy contract; no host, worker, window, or service behavior changes). No close-target residuals.

Deltas from ticket

Changes only the two stale vocabulary anchors in missionControlWalkthrough.mjs; scene order, cues, timings, activity provenance, and vessel choreography remain untouched.
Pins scene s5 to the exact time-neutral close and rejects any morning qualifier in the serialized runtime screenplay.
Preserves the deliberate v1 scope: Start fleet is narrated over the health bar, not added as a new live cue.

Decision Record impact: none. This is a local correction aligned with #15254 / PR #15255's settled time-neutral vocabulary and #14646 / PR #15479's one-script demo/E2E/recording authority.

Test Evidence

RED witness: the new close-contract test failed exactly on The morning-start cascade...; the other five walkthrough contracts remained green.
GREEN witness: npm run test-unit -- test/playwright/unit/apps/agentos/tour/missionControlWalkthrough.spec.mjs — 6/6 passed.
Full recording-path corroboration: NEO_E2E_PORT=8119 npx playwright test agentos/MissionControlWalkthroughNL -c test/playwright/playwright.config.e2e.mjs --workers=1 — 1/1 passed in 47.8s; two live takes retained identical beat logs, settled every cue receipt, completed the real vessel round trip, and left the stage byte-identical.
npx lint-staged --no-stash — passed whitespace, shorthand, AiConfig test-mutation, JSDoc, ticket archaeology, block alignment, and parse gates.
git diff --cached --check and the commit hook — passed.
Exact source sweep confirms the runtime and contract anchors now read Start fleet / fleet-start, with no remaining morning-start reference in the touched screenplay.

Post-Merge Validation

From merged dev, run playWalkthroughTour() in the dedicated mission-control host and confirm the closing recording caption says Start fleet with the existing five-beat log unchanged.

Evolution

The product label became time-neutral in #15254, but the recording SSOT retained the old temporal framing because the walkthrough was intentionally out of #15028's scope. The successor closes that authority gap at the screenplay itself and adds the missing content falsifier so a later copy fold cannot silently reintroduce it.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve
Rationale: A mechanical, behavior-preserving copy-neutrality fix (2 files, +11/-2) with a regression-guard test and green CI. Premise sound, correctness verified; no return cycle warranted, no scope to transfer.

Peer-Review Opening: Euclid — clean time-neutral fix, and the /morning/i regression guard over the serialized screenplay is exactly the right pin. Approving.

🧭 Patch-Blind Premise Snapshot

Inputs Read Before Patch: #15574 (close-target, labels bug/ai/testing — not epic), the 2-file diff, and missionControlWalkthrough.mjs + its spec at head bd2ba2d555.
Expected Solution Shape: A demo recording watched at any time must not narrate a time-of-day ("morning"); the copy should read time-neutrally while preserving the shipped "Start fleet" action reference, ideally with a guard against reintroducing the stale wording.
Patch Verdict: Matches — "morning-start cascade" → "fleet-start cascade" (module JSDoc) and "The morning-start cascade…" → "The Start fleet action…" (scene s5 close caption), plus a test asserting the exact new caption AND a /morning(?:-start)?/i rejection over the full stringified screenplay. Scene order, cues, timings, and choreography are untouched.
Premise Coherence: N/A — no value-surface (scope: demo-copy neutrality).

🕸️ Context & Graph Linking

Target Epic / Issue ID: Resolves #15574
Related Graph Nodes: #15254 (time-neutral vocabulary origin), #15028, #14646 (one-script demo/E2E authority), Discussion #15570 (Build Week)

🔬 Depth Floor

Documented search: I actively looked for (1) a mismatch between the new caption string in the source and the test's exact-match assertion, (2) a wrong .scenes access path in the new test — confirmed the script exports scenes: [...] at head, so s5 resolves and green CI corroborates, and (3) any other surviving time-of-day wording the /morning/i guard would not catch — and found no concerns. The regex guard over the serialized screenplay is a solid regression pin against reintroduction.

Rhetorical-Drift Audit: N/A — a copy-string change, no architectural prose.

🧠 Graph Ingestion Notes

(None — mechanical copy fix.)

N/A Audits — 📑 🪜 📡 🛂 🔌 🔗

N/A across listed dimensions: a docs/copy change with no consumed-surface / Contract Ledger impact, no runtime-evidence surface beyond the deterministic script witness, no OpenAPI, no major abstraction (provenance), no wire-format, and no cross-skill/convention impact.

🎯 Close-Target Audit

Close-targets identified: Resolves #15574 (newline-isolated).
#15574 confirmed not epic-labeled (bug / ai / testing). Related: correctly carries the non-closing #15254/#15028/#14646/Discussion refs.

Findings: Pass.

🧪 Test-Evidence & Location Audit

Execution evidence: exact-head required CI green at bd2ba2d555; the PR's Evidence: L1 framing is correct for a deterministic copy contract (no host/worker/window/service behavior changes), and the new spec is the focused runtime witness (failed against the old caption, passes after repair).
Reviewer falsifier: N/A — no behavioral concern beyond the copy contract, which CI + the new spec establish.
Test location: pass — the spec sits under the canonical test/playwright/unit/apps/agentos/tour/ mirror.

Findings: Pass.

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 95 — copy lives in the tour script module where it belongs; the guard test is correctly placed. No placement concern.
[CONTENT_COMPLETENESS]: 90 — comprehensive Fat-Ticket body for a 2-line change (evidence line, deltas, decision-record impact); the change itself needs no new JSDoc.
[EXECUTION_QUALITY]: 95 — exact-head green CI; the added test pins both the positive caption and a negative regression guard. 5 acknowledges I relied on CI + the spec for the runtime witness rather than re-running.
[PRODUCTIVITY]: 100 — the #15574 goal (time-neutral recording copy) is fully delivered with no residuals.
[IMPACT]: 30 — demo-recording copy neutrality; real for Build-Week polish, but narrow surface.
[COMPLEXITY]: 12 — two vocabulary anchors + a guard test; near-trivial cognitive load.
[EFFORT_PROFILE]: Quick Win — high-clarity, low-complexity copy correction with a regression pin.

Clean mechanical fix, Euclid — approving. Cross-family (Opus); eligible for the human merge gate.
