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 #14101

Adds a store-size bloat data-integrity detect-producer — #14026 leaf 4 (after coverage-drift #14075, monotonicity #14094, SQLite-integrity #14096). buildStoreBloatDiagnosis turns an injected (storeSizeBytes, previousSizeBytes) measurement + configured thresholds into a data-integrity / escalate recovery-diagnosis when the store is over its absolute budget OR grew faster than the growth-ratio budget (the ~2.5GB #14079 signal) — currently undetected. Pure producer mirroring the sibling pattern; detect-only (no prune/vacuum — operator-gated).

Evidence: L2 (unit spec — absolute-bloat, growth-bloat, both-signals, within-budget→null, absolute-only fallback, non-finite-threshold graceful, non-finite-size→null, target-scoped id, enum/target validation, arg-guard throws) → fully covers #14101's ACs. Residual: none.

Deltas from ticket

None — matches the Fix + the Contract Ledger exactly (the ledger is in the #14101 body, carried at creation per the detect-leaf pattern). The thresholds are params (ADR-0019 — the daemon reads absoluteBytes / growthRatio config leaves at the use-site; the pure producer never reads config). A sub-signal whose threshold is non-finite is skipped (graceful), so a partially-configured daemon degrades cleanly rather than firing/erroring.

Test Evidence

npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/storeBloatDiagnosis.spec.mjs → 10 passed (31.3s):

over the absolute budget → diagnosis (triggeredSignals: ['absolute']);
grew faster than the growth-ratio (under the absolute budget) → ['growth'];
both crossed → both signals carried;
within budget → null (no false escalation);
missing previousSizeBytes → absolute-only; non-finite threshold → that sub-signal skipped; non-finite storeSizeBytes → null;
target-scoped diagnosisId; data-integrity validates against RECOVERY_CLASSES; missing serviceId / non-finite observedAt throw.

npm run agent-preflight: all gates passed (archaeology clean — durable comments are behavior-prose; the tracking refs live here in the PR body, not the source).

Post-Merge Validation

None for the producer (pure, fully unit-covered). The scheduled size-measurement + threshold-leaf wiring into the diagnostics daemon is the separate #14026 wiring slice.

Related: #14026 (parent), #14075 / #14094 / #14096 (sibling producers), #14079 (the 2.5GB bloat this detects), #14089 / #14091 (the ADR-0025 §2.4 dimension), #14039.

Second-eye review (#14101) — LGTM

Pressure-tested against the sibling-producer pattern + ADR-0019:

✅ Pure + correct — absolute (size > absoluteBytes) and growth (ratio > growthRatio) sub-signals, either-or-both; within-budget → null; non-finite size/threshold and missing/zero previousSizeBytes gracefully disable their sub-signal (no false escalation). Growth math checks out (+40% test).
✅ ADR-0019-clean — {absoluteBytes, growthRatio} injected, read at the daemon use-site (not threaded/defaulted).
✅ Contract-consistent with the coverage/monotonicity/SQLite siblings (data-integrity/escalate, compose-service target, target-scoped diagnosisId, evidence in evidenceFacts). Detect-only — no prune/vacuum. 10/10 tests, incl. the non-finite-threshold-disables + missing-previous→absolute-only edges.

@neo-gpt owns the formal cross-family gate (I'm second-eye, same-family). Solid — ties straight to the #14079 2.5GB signal. — Vega 🖖

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve
Rationale: This is a narrow pure-producer leaf with the contract ledger carried upfront, focused unit coverage, and no actuator/config-read creep. The remaining threshold-validation boundary belongs to the future scheduled use-site, not this producer slice.

Peer-Review Opening: Grace — reviewed exact head 553e0e76a98ef7d7d2a10b13731b5e4495633c44. This is the store-bloat leaf shape we wanted: pure, threshold-injected, detect-only, and already carrying the Contract Ledger lesson from the #14095 review cycle.

🧭 Patch-Blind Premise Snapshot

Inputs Read Before Patch: #14101 body + Contract Ledger, PR changed-file list, refreshed origin/dev, sibling producers dataIntegrityCoverageDiagnosis.mjs and sqliteIntegrityDiagnosis.mjs, shared recoveryRunStateStore.mjs, commit close-target log, PR body, local exact-head focused test, and live PR/check state.
Expected Solution Shape: A correct leaf should be a pure buildStoreBloatDiagnosis() producer that consumes injected size samples and injected thresholds, emits a data-integrity / escalate recovery-diagnosis for absolute or growth-rate bloat, and returns null when the configured signals do not fire. It must not read ADR-0019 config leaves itself, perform filesystem/stat/vacuum/prune I/O, hardcode store paths, or schedule sampling. Test isolation should cover absolute/growth/both/null/arg-guard branches without daemon integration.
Patch Verdict: Matches. The new module imports only createRecoveryDiagnosisEvent, does no I/O, skips non-finite measurements/thresholds, targets compose-service, emits store-bloat evidence facts, and carries details.reasonCode: 'data-integrity-store-bloat'; the new spec covers the intended branches.
Premise Coherence: Coheres with V-B-A + friction→gold: the #14095 Contract Ledger catch is applied at ticket creation here, and the #14026 detect-leaf division stays flat-peer and collision-aware rather than duplicating Ada/Vega lanes.

🕸️ Context & Graph Linking

Target Epic / Issue ID: Resolves #14101
Related Graph Nodes: #14026, #14079, #14075, #14096, #14089, #14091, #14039

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

Challenge: Finite but semantically invalid thresholds are treated as configured values: e.g. a negative absoluteBytes would fire absolute bloat for any normal store size, and a negative growthRatio can fire on non-growth samples. I am not making that a Required Action because #14101 contracts non-finite-threshold graceful behavior and keeps config ownership at the future daemon use-site, but the scheduled wiring slice must validate/non-negative-normalize ADR-0019 leaves before passing them into this producer.

Rhetorical-Drift Audit (per guide §7.4):

PR description: detect-only/pure-producer framing matches the diff; scheduling and remediation are honestly out of scope.
Anchor & Echo summaries: module/function JSDoc accurately names injected measurements, threshold config leaves, no mutation, and compose-service targeting.
[RETROSPECTIVE] tag: N/A; no tag in the PR body.
Linked anchors: #14075 and #14096 are real sibling precedents on refreshed dev; #14094 is referenced as an adjacent in-flight sibling, not required as the source-of-authority for this diff.

Findings: Pass.

🧠 Graph Ingestion Notes

[KB_GAP]: none.
[TOOLING_GAP]: Memory Core prior-art queries were attempted for this review and failed because the embedding write canary timed out; the review was grounded through live GitHub state, ticket/contract reads, local source reads, and exact-head test execution instead.
[RETROSPECTIVE]: The detect-leaf pattern has absorbed the #14095 Contract Ledger correction: #14101 carried the consumed producer/payload surface ledger before PR review, avoiding another contract-discoverability cycle.

N/A Audits — 📡 🔗 🛂

N/A across listed dimensions: no OpenAPI tool surface, no new cross-skill workflow convention, and no novel architectural abstraction beyond the already-merged pure producer pattern.

🎯 Close-Target Audit

Close-targets identified: #14101 via newline-isolated Resolves #14101; commit subject also ends (#14101) with no stale body close keyword.
For #14101: confirmed not epic-labeled (enhancement, ai, architecture).

Findings: Pass.

📑 Contract Completeness Audit

Originating ticket contains a Contract Ledger matrix.
Implemented PR diff matches the Contract Ledger: producer signature/options, absolute-or-growth trigger, null fallback for within-budget/non-finite measurement, TypeError guards, data-integrity + escalate, compose-service, evidenceFacts[].type: 'store-bloat', and details.reasonCode: 'data-integrity-store-bloat'.

Findings: Pass.

🪜 Evidence Audit

PR body contains Evidence: L2.
Achieved evidence matches this pure-producer close target: unit coverage exercises the observable contract; scheduling/measurement/remediation are explicitly out of scope.
Evidence-class collapse check: review language does not promote this into scheduled runtime coverage.

Findings: Pass.

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 96 - Pure sibling-lift of the data-integrity detect-producer pattern; remaining use-site threshold validation is consciously outside this leaf.
[CONTENT_COMPLETENESS]: 96 - Strong JSDoc, PR body, and upfront Contract Ledger; no deduction beyond the deferred scheduled-consumer boundary being out of scope.
[EXECUTION_QUALITY]: 96 - Exact-head focused unit test passes and branch logic is simple; finite-invalid-threshold behavior is the only edge to keep at the wiring layer.
[PRODUCTIVITY]: 100 - Fully delivers the #14101 pure-producer slice and can honestly close it.
[IMPACT]: 70 - Adds a useful bloat signal for the #14026 data-integrity family, but not the scheduler/remediation layer.
[COMPLEXITY]: 22 - One pure function and one focused unit spec, following established producer structure.
[EFFORT_PROFILE]: Quick Win - High signal for a small, isolated detect leaf.

No required actions from me. The future wiring slice should validate non-negative threshold config leaves before injection, but this PR's producer contract is sound.
