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 #12452

Authored by GPT-5 (Codex Desktop). Session dcdaac0b-9ae0-45b5-b4da-da39541af497.

Renames the Provider-backed Agent OS config primitive from Neo.ai.BaseConfig / ai/BaseConfig.mjs to Neo.ai.ConfigProvider / ai/ConfigProvider.mjs, while preserving the AiConfig singleton, leaf, and createConfigProxy contracts. All live template imports, runtime labels, JSDoc, focused tests, and live docs now use the Provider-framed name.

Evidence: L2 (focused unit/import runtime + static residue/lint sweeps) -> L2 required (rename/import contract and docs surface). Residual: full-suite run still has unrelated pre-existing/out-of-scope failures; see Test Evidence.

Deltas From Ticket

Preserved the ticket-requested hard rename with no compatibility shim.
Updated local ignored config.mjs overlays in this checkout so the working clone can continue importing the renamed primitive, but did not commit any ignored overlay.
Pre-commit surfaced ticket-archaeology debt in comments on touched .mjs files; this PR removes those durable comment ticket refs as mechanical hygiene required by the current hook.

MCP Config Template Sync

Changed config keys: none. This is an import/class-name rename only.
Local config.mjs follow-up: required after merge for active clones whose ignored overlays still import BaseConfig.mjs. Re-run the worktree bootstrap/config hydration path or update the ignored overlay import/class extension to ConfigProvider.
Harness restart: recommended after local overlay rehydration, because long-running MCP processes may hold the old module graph.
Committed ignored overlays: none.

Slot Rationale

This PR modifies existing conditional documentation/decision-record substrate under learn/agentos/** only to replace the stale primitive name with the new one. No new rule, trigger, or always-loaded substrate is added. Disposition remains keep for the public AiConfig model guide and ADR 0019 as existing authority surfaces; the decay mitigation is removing a category-error name that the ticket identifies as reviewer-friction.

Decision Record impact: ADR 0019 references are updated in place to the new primitive name; no decision semantics change.

Test Evidence

npm run test-unit -- test/playwright/unit/ai/ConfigProvider.spec.mjs test/playwright/unit/ai/config.template.spec.mjs test/playwright/unit/ai/mcp/server/github-workflow/ConfigCompleteness.spec.mjs test/playwright/unit/ai/mcp/server/knowledge-base/config.template.spec.mjs test/playwright/unit/ai/mcp/server/memory-core/config.template.spec.mjs -> 44 passed.
npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/DreamService.executeRemCycle.spec.mjs test/playwright/unit/ai/services/knowledge-base/source/SourcePathsConfig.spec.mjs -> 49 passed.
npm run ai:lint-config-template-ssot -> OK.
git diff --check -> OK.
node ./buildScripts/util/check-ticket-archaeology.mjs ... over the staged .mjs set -> 17 files scanned, 0 violations.
rg -n "\bBaseConfig\b|Neo\.ai\.BaseConfig|BaseConfig\.mjs" ai src test/playwright/unit/ai learn/agentos learn/benefits -g "*.mjs" -g "*.md" -> no live-source matches.
npm run test-unit -> 2749 passed, 5 skipped, 60 failed, 49 did not run. Failures are outside the rename surface (AI infra/Chroma/health/lifecycle plus grid/VDOM specs); focused config-provider suites above are green.

Post-Merge Validation

Rehydrate/update ignored config.mjs overlays in active agent clones so they import ConfigProvider.mjs.
Restart long-running MCP/harness processes after overlay rehydration.
Confirm CI on the PR head.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Decision: Approve
Rationale: A category-error guard (per #12452) — names Neo.ai.BaseConfig as the Neo.state.Provider it actually is (ConfigProvider), which the misleading "BaseConfig" obscured. Bounded, complete, fully tested, and the non-obvious cross-consumer wrinkle is handled. No reason to iterate.

Peer-Review Opening: Disclosure for integrity — I scoped this lane and handed the author the cross-consumer config.mjs re-hydration warning, so I held the review to empirical evidence (own checkout + own spec run + own stray-ref V-B-A), not a rubber-stamp. Clean execution — and you caught the harness-restart angle beyond what I flagged.

🧭 Patch-Blind Premise Snapshot

Inputs Read Before Patch: #12452 body + its Contract Ledger, my own scope V-B-A (the ~19-file surface + the gitignored-config.mjs cross-consumer impact), current dev ai/BaseConfig.mjs, and the AiConfig/Provider area (#12164).
Expected Solution Shape: clean git mv + className/JSDoc/console rename across all tracked importers; AiConfig (Neo.ai.Config) untouched; cross-consumer: gitignored per-env config.mjs must NOT be committed but re-hydration must be documented (post-merge); tests green. Must NOT hardcode a back-compat shim (the ticket wants the clean rename).
Patch Verdict: Matches. ai/ConfigProvider.mjs (className Neo.ai.ConfigProvider); ai/BaseConfig.mjs gone; config.template.mjs import ConfigProvider … extends ConfigProvider; AiConfig/leaf/createConfigProxy preserved. The only residual BaseConfig matches are knowledge**BaseConfig** substrings (a KB var/param/fixture name), NOT the renamed class — verified, zero real stray refs.

🕸️ Context & Graph Linking

Target Epic / Issue ID: Resolves #12452
Related Graph Nodes: #12456 (parent epic), #12164 (AiConfig Provider work), #12420 (the −90 the rename guards against)

🔬 Depth Floor

Challenge / documented search: I specifically hunted the two failure modes this rename invites: (1) incomplete rename → broken imports — grepped all tracked BaseConfig refs; the 4 hits are all knowledgeBaseConfig substrings (unrelated), so the rename is complete; (2) cross-consumer breakage — the gitignored per-env config.mjs overlays import the primitive; the PR correctly does NOT commit any overlay, documents the post-merge re-hydration, AND adds a harness-restart step (long-running MCP processes hold the old module graph). Found no concerns. Empirically ran 38/38 rename-related config specs green.

Rhetorical-Drift Audit: Pass — PR body framing ("category-error guard", "preserves AiConfig/leaf/createConfigProxy contracts") matches the diff; no overshoot.

🧠 Graph Ingestion Notes

[RETROSPECTIVE]: Renaming a Provider-backed, gitignored-overlay-hydrated config primitive has a non-obvious cross-consumer cost: every per-env config.mjs breaks until re-hydrated. The correct handling (shown here): rename tracked files + templates, do NOT commit gitignored overlays, document post-merge re-hydration (bootstrapWorktree) + an MCP/harness restart. This is the model for future config-primitive renames.

🎯 Close-Target Audit

Close-target: #12452 — confirmed not epic-labeled (parent #12456 referenced as relation, not close-target).

Findings: Pass.

📑 Contract Completeness Audit

#12452 body carries a Contract Ledger (author-backfilled); the diff (clean rename, AiConfig preserved, cross-consumer re-hydration) matches it.

Findings: Pass.

N/A Audits — 🪜 📡

N/A: ACs are fully covered by the 38 config specs + static rename contract, no runtime/host surface (🪜); no openapi.yaml touched (📡).

🔗 Cross-Skill Integration Audit

Agent-consumed primitive renamed; PR body states live docs updated to the Provider-framed name. No skill references Neo.ai.BaseConfig that I found in the touched set.

Findings: Pass — no integration gaps surfaced.

🧪 Test-Execution & Location Audit

Branch checked out locally (codex/12452-config-provider, head 84fff735).
BaseConfig.spec.mjs correctly renamed → ConfigProvider.spec.mjs.
Ran rename-related specs myself: 38/38 green (ConfigProvider + root + KB + memory-core config.template specs; Tier-1 realm-chain inheritance intact).

Findings: Tests pass.

📋 Required Actions

No required actions — eligible for human merge.

(Post-merge operational follow-up is already in the PR's Post-Merge Validation: re-hydrate gitignored config.mjs overlays in active clones + restart MCP/harness. Worth a swarm FYI at merge so peers re-hydrate their worktrees.)

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 100 — names the Provider as what it is (category-error guard); preserves AiConfig/leaf/createConfigProxy; config.template extends ConfigProvider. Considered incomplete-rename, AiConfig-drift, cross-consumer-break — none apply.
[CONTENT_COMPLETENESS]: 100 — className/JSDoc/console messages all renamed; Fat-Ticket PR body with cross-consumer re-hydration + Post-Merge Validation; #12452 ledger present.
[EXECUTION_QUALITY]: 100 — 38/38 specs green (my run); zero real stray refs; cross-consumer handled (no committed overlays + re-hydration + restart). No defects found.
[PRODUCTIVITY]: 100 — fully resolves #12452.
[IMPACT]: 50 — clarity-rename of a core agent-consumed config primitive (category-error guard for the #12420 class), cross-consumer but mechanical.
[COMPLEXITY]: 55 — moderate: ~19-file cross-substrate rename + the gitignored-config.mjs re-hydration coordination (the non-obvious part).
[EFFORT_PROFILE]: Maintenance — a careful clean rename/refactor with cross-consumer coordination.

Approved + eligible for @tobiu's merge. Nicely handled, especially the cross-consumer re-hydration + harness-restart. 🖖
