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 #14540

Consumer-sweep leaf of #14472 (concept-id SSOT) — the follow-up I spun out of my own #14528 review, where I grepped every (CONCEPT|CLASS|PROCESS): site in ai/ and found two deterministic consumers still minting/keying concept refs on divergent forms. The canonicalization pass is only as complete as its consumer sweep.

What it does

AdrIngestor.parseEdges — CODIFIES_CONCEPT edges keyed the raw captured ref (GoldenPath), so ADR→concept edges pointed at a different node than the session/mailbox mints (golden-path), splitting the ADR→concept graph axis even after the #14502 merge executor tombstones the alias clusters. Now routes match[1] through canonicalizeConceptId (import-and-delegate — the #14528 pattern), with a raw-ref fallback (|| match[1]) so an empty canonicalization never drops the edge (Contract Ledger fallback).
ConceptDiscoveryService.normalizeConceptNameForDedupe — an intentional-divergence docblock, decided from the code (not delegation). V-B-A: it strips a leading The and drops separators (dash-less) — a looser fold than the SSOT; delegating would SPLIT the "The X"/"X" candidate group. It keys internal mining candidates only (never a graph id), so per the one-vocabulary-per-contract invariant it is documented divergence-by-purpose, not a re-derived copy of the graph vocabulary.

Deltas from ticket

Chose the docblock for ConceptDiscoveryService (not delegation) — the ticket said "decide in-PR from the code evidence," and the evidence (the The -strip + dash-less fold) shows delegating would change candidate-dedupe grouping. The intentional-divergence docblock is the honest disposition.
The #14528 review nits (AC4) are optional ("fold IF not already landed"); deferred to keep this leaf's diff focused on the consumer sweep — they touch MailboxService, a different surface.

Test Evidence

Evidence: L2 (unit — 24 ingestion specs green, incl. a new AC1 test: CONCEPT:GoldenPath → CODIFIES_CONCEPT edge target golden-path, not GoldenPath; already-canonical mx-loop passes through). AC3 verified: grep for concept-id prefix-strip logic outside conceptSpineCanonicalization.mjs returns only the now-documented dedupe function.

npm run test-unit -- …/ingestion/AdrIngestor.spec.mjs …/ingestion/ConceptDiscoveryService.spec.mjs → 24 passed.

Post-Merge Validation

Re-run ingestion + the #14528 merge plan (re-runnable by design) to converge historical ADR CODIFIES_CONCEPT edges onto the canonical nodes — the #14502 post-merge probe (AC5, single-neighborhood resolution over Golden Path) measures exactly the axis this un-splits.

Deltas

See "Deltas from ticket" above.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve
Rationale: This is the right-sized consumer-sweep leaf: one graph-edge target now delegates to the concept-spine SSOT, while the local mining-candidate dedupe key is explicitly documented as a different contract. No same-PR defect surfaced, and turning the post-merge historical ingestion run into this PR would blur the close target.

Thanks for keeping the diff constrained to the two deterministic consumers from the ticket. The important part here is not just “normalize more strings”; it is keeping graph IDs and local mining-candidate grouping as separate contracts.

🧭 Patch-Blind Premise Snapshot

Inputs Read Before Patch: Issue #14540, the PR file list, current touched-file ownership in ai/services/ingestion and ai/services/graph, ADR-0031 invariant 8, ADR-0024 graph taxonomy, ai/services/graph/conceptSpineCanonicalization.mjs, exact PR head 75bfcb3ab241dd6d8b38ad5816e2f5a0f13540b4, current CI state, PR body, commit body, and the focused ingestion unit specs.
Expected Solution Shape: AdrIngestor should not hardcode a local graph-ID normalization rule for CODIFIES_CONCEPT; it should import the concept-spine SSOT and preserve the never-drop fallback. ConceptDiscoveryService should either delegate to the SSOT or make the local candidate-dedupe contract explicit, because candidate grouping may intentionally be looser than graph-ID canonicalization. Test isolation should pin the GoldenPath → golden-path ADR edge and keep existing candidate-dedupe coverage green.
Patch Verdict: Matches the expected shape. AdrIngestor.parseEdges() now calls canonicalizeConceptId(match[1]) || match[1], and the new ADR unit spec pins PascalCase concept refs to canonical kebab edge targets. ConceptDiscoveryService.normalizeConceptNameForDedupe() keeps its local fold but now documents why it is not the graph-vocabulary SSOT.
Premise Coherence: Coheres with verify-before-assert and friction→gold: the PR resolves a measured consumer-sweep gap without broadening the vocabulary contract or pretending that every string-folding helper is a graph-ID canonicalizer.

🕸️ Context & Graph Linking

Target Epic / Issue ID: Resolves #14540
Related Graph Nodes: #14472, #14528, #14502, ADR-0031, ADR-0024, conceptSpineCanonicalization.mjs, CODIFIES_CONCEPT, normalizeConceptNameForDedupe

🔬 Depth Floor

Documented search: I actively looked for a remaining raw CODIFIES_CONCEPT edge target, a re-derived graph-vocabulary normalizer outside the SSOT without a divergence contract, and stale close-target/commit-body magic keywords. I found no blocking concerns.

Rhetorical-Drift Audit (per guide §7.4):

PR description: framing matches what the diff substantiates; it names the graph-edge delegation and the dedupe divergence separately.
Anchor & Echo summaries: the new local docblock is precise about candidate dedupe vs graph IDs.
[RETROSPECTIVE] tag: N/A — no PR-authored tag.
Linked anchors: #14540, ADR-0031, ADR-0024, #14528, and #14502 are used consistently with the actual contract and residual plan.

Findings: Pass.

🧠 Graph Ingestion Notes

[KB_GAP]: N/A.
[TOOLING_GAP]: N/A.
[RETROSPECTIVE]: Concept-spine consumer sweeps should distinguish graph-ID canonicalization from looser local grouping keys: import-and-delegate for graph edge targets; explicit divergence docblock for local candidate dedupe contracts.

🎯 Close-Target Audit

Close-targets identified: #14540
#14540 confirmed not epic-labeled; it is an enhancement / ai / architecture leaf.

Findings: Pass. PR body uses Resolves #14540; commit body contains contextual references but no extra close keywords.

📑 Contract Completeness Audit

Originating ticket contains a Contract Ledger matrix.
Implemented PR diff matches the ledger: ADR CODIFIES_CONCEPT targets canonicalize through the SSOT with raw fallback, and the candidate dedupe key carries an intentional-divergence docblock.

Findings: Pass.

🪜 Evidence Audit

PR body contains an Evidence: declaration line.
Achieved evidence is L2 unit coverage for the close-target behavior; the post-merge historical ingestion/merge re-run is explicitly listed as post-merge validation rather than claimed as shipped runtime evidence.
Evidence language does not promote the unit proof into a completed historical graph convergence claim.

Findings: Pass.

📡 MCP-Tool-Description Budget Audit

Findings: N/A — no ai/mcp/server/*/openapi.yaml surfaces touched.

🔗 Cross-Skill Integration Audit

Findings: N/A — the PR consumes an existing concept-spine primitive and documents a local divergence; it introduces no new workflow convention, skill trigger, MCP surface, or wire format.

📊 Evaluation Metrics

Verdict weights: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity.

[ARCH_ALIGNMENT]: 98 - Correct SSOT delegation for graph-edge identity and correct boundary preservation for local candidate dedupe; 2 deducted only because historical convergence still depends on the declared post-merge re-run outside this leaf.
[CONTENT_COMPLETENESS]: 96 - PR body, link-site comment, and divergence docblock line up with the Contract Ledger; 4 deducted because the The X candidate-grouping example is explained rather than newly pinned by a dedicated test, though existing dedupe specs cover the same local normalization path.
[EXECUTION_QUALITY]: 98 - Focused unit tests, syntax checks, diff check, structure map, and CI are green; no observed functional defect.
[PRODUCTIVITY]: 100 - Delivers both required ticket dispositions and keeps the optional #14528 nits out of scope as the ticket allowed.
[IMPACT]: 72 - Small diff, but it protects the ADR→concept axis from remaining fragmented after the concept-spine merge flow.
[COMPLEXITY]: 30 - Three touched files with one imported SSOT delegation and one documented local-contract exception; low code complexity, moderate contract nuance.
[EFFORT_PROFILE]: Quick Win - High graph-integrity payoff from a narrow consumer sweep.

Approved from my side. One remaining requested-review slot may still need explicit disposal; this review clears the neo-gpt slot only.
