Verification-first Claude Code consulting

We don't guess.
We verify.

AI Architect is a consulting practice that activates verified AI agents inside your infrastructure — on the same stack we ship in production: 98.20% recall (MRR 0.9166) on LongMemEval, 5 fused retrieval signals, zero LLM-judges-LLM. Every output is traceable, every claim is checked — by deterministic algorithms, not by another model's opinion.

The zetetic standard

Four principles. No exceptions.

Zetetic comes from zētēsis — Greek for inquiry. Truth is something you investigate, not something you assume. Everything we ship enforces this.
i. PROVENANCE

Every claim has a source.

If an agent states a fact, that fact ties back to a memory, a file, a commit, or a citation. No assertion lives without a trail.

ii. ALGORITHM > OPINION

Zero LLM-judges-LLM.

Verification is deterministic: graph analysis, semantic checks, atomic claim decomposition. We don't ask one model whether another model is right.

iii. MEMORY THAT LEARNS

Compounding context.

Cortex applies neuroscience — spreading activation, consolidation cycles, microglial pruning — so agents remember what worked, not just what happened.

iv. AUDITABLE

Built for regulated work.

Every PRD, PR, decision and reasoning step is logged and reviewable. Designed against the same bar as financial-systems software.

Verification, in the open

Watch an agent prove its work.

This is the actual verification report from a generated PRD. 64 atomic claims, decomposed and checked against six independent algorithms. The full audit trail lives next to the deliverable — not buried in a log file.

Tooling of the engagement

The instruments we bring to every engagement. Not the offer — the toolkit.

These aren't what you're buying — they're what we run during an engagement. Cortex remembers, Zetetic reasons, Codebase maps, AI Architect Spec adjudicates. Every one ships open source, so you can inspect exactly what touches your systems.
Two ways to start

Hire us to build it. Or build it yourself with our tools.

Every component is open source, MIT-licensed, and shipping in production. The choice is whether you want the system handed to you — or the keys to do it yourself.

How engagements run

From entry audit to rollout. Four exhibits.

Every engagement runs the same sequence — no slide decks, no "AI transformation" theater. Each stage produces a visible, dated artifact before we ask for the next commitment.

EXHIBIT 01 · ENTRY AUDIT

Entry audit

An inventory of your AI surface — what tooling already exists, what's shadow IT, where knowledge quietly drifts between systems. This document is yours to act on, with or without us.

See how we run this
EXHIBIT 02 · ACTIVATION

Claude Code activation

Scope, deploy, configure, run — the same activation sequence every time. We wire Claude Code into your real repos, your real data, your real review process.

See how we run this
EXHIBIT 03 · PAID PILOT

Paid pilot

A scoped, paid pilot against one real workflow, with deliverables visible as they ship — no black box. You watch the agent work before committing to anything past the pilot.

See how we run this
EXHIBIT 04 · ROLLOUT

Rollout

Two ways to run it in production: the local edition, on your own infrastructure with no dependency on us, or Claude Enterprise, managed with org-wide memory and governance. Either way, you own what ships.

About

I ship critical systems by day. I research how agents should think by night.

By day I build software in financial infrastructure, where "mostly works" never ships. Every system has to be tested, verified, auditable. Or it doesn't go live.

By night I apply that same bar to AI. I started AI Architect because I kept seeing the same anti-pattern: teams treating agents like demos, stacking prompts on prompts, asking another LLM whether the first one got it right, and wondering why nothing held up in production.

The work here is zetetic — every claim is investigated, never assumed. The tools are open source because the frontier should be shared. The consulting exists because some teams need the system built with them, not handed a repo and a prayer.

"An agent without memory isn't intelligent. An agent without verification isn't trustworthy. I'm only interested in building both."

2 papers in review · seeking arXiv endorsement · cs.IR

The papers behind the numbers.
Read them. Help us publish.

arXiv requires an endorser in cs.IR for first-time authors. Two preprints are ready — a third on HALO retrieval is in progress. Both drafts below are the work behind the LongMemEval, LoCoMo, and BEAM results on this page. If you've published in cs.IR and find them useful, a single endorsement gets each to the open scientific record.

Stage-Aware Context Assembly for Long-Context Memory Retrieval

Clément Deust · Independent Researcher
+33.4%MRR · vs BEAM oracle
0.471MRR · BEAM-10M
8 / 10memory abilities improved

A structured context-assembly architecture that recovers the geometric degradation of dense vector retrieval at the 10M-token scale. Two primitives: a priority-budgeted prompt decomposer with domain-aware condensers, and a two-phase stage-aware assembler with submodular coverage selection, Personalized PageRank entity-graph traversal, and schema-structured summary fallback.

On BEAM-10M, the assembler reaches 0.471 MRR — +33.4% over the flat baseline, with 8 of 10 memory abilities improving. Originally designed in September 2025 for Apple Intelligence's 4,096-token window — one month before the BEAM benchmark itself was published.

Looking for an endorser arXiv's policy requires an existing cs.IR author to endorse first-time submitters. If you've published in cs.IR and you find this useful, a single endorsement is enough — the rest is automated. Reach out below or open an issue on the repo.

Thermodynamic Memory vs. Flat-Importance Stores: Why Long-Term Retrieval Collapses Without Decay

Clément Deust · Independent Researcher
98.4%R@10 · LongMemEval
94.2%R@10 · LoCoMo
0.591Overall · BEAM

External memory for LLMs is dominated by flat-importance stores — vector indexes, BM25 corpora, long-context buffers — in which every item carries the same long-term retrieval prior. This design is asymptotically broken: as the corpus grows, top-k retrieval degenerates into near-arbitrary tie-breaking.

This paper formalises the collapse and describes Cortex, a memory architecture that maintains a non-flat priority distribution across N by coupling four mechanisms: continuously decaying heat (Ebbinghaus), a hierarchical predictive-coding write gate (Friston), consolidation cascades (Kandel, McClelland), and WRRF fusion with heat as tie-breaker. The figures above are this paper's own measurement run (May 2026); the live shipped-code numbers on this page (98.20% / 91.35%) come from the v4.14.3 release-tree verification and supersede these as the current benchmark of record.

Looking for an endorser Same endorsement ask as paper #1 — both submissions are independent. If you can endorse only one, this one establishes the underlying principle the other builds on.

Forthcoming — preprint #3: HALO retrieval. Drafting in progress; will join the same endorsement queue once complete.

Common questions

Before you
book a call.

Yes. Most non-tech clients bring a business problem and access to their systems; we bring the engineering. Every check-in uses plain language and working demos, not jargon. The whole point of the verification standard is so you can trust what's shipping without needing to read the code.
Most "AI verification" is one model asking another model whether the first one is right. That's not verification — it's polling. We use deterministic algorithms instead: graph analysis to detect contradictions, atomic claim decomposition, semantic alignment scoring against a fixed corpus, and consensus across independent checks. Math, not vibes.
A typical first engagement is 4–6 weeks, scoped to a single high-value workflow. Pricing depends on integrations and scope — you'll get a concrete number within 48 hours of the discovery call. Not a vague range, not a "starting at."
In your infrastructure — AWS, GCP, on-prem, your call. Cortex is local-first by design (SQLite by default, PostgreSQL + pgvector optional), no GPU. Your data never passes through a server we own. For regulated industries, the deployment plugs into your existing security model.
Please do. Everything is on GitHub, MIT-licensed, and documented. Open an issue if you get stuck — every one of them gets read. The consulting is for teams who'd rather have it implemented with them than figure it out from the README.
Cortex is a biologically-inspired persistent memory MCP server for Claude Code. Verified on the v4.14.3 release tree: LongMemEval-S MRR 0.9166 / Recall@10 98.20% (ICLR 2025), LoCoMo 3-run mean MRR 0.7998 / Recall@10 91.35% (ACL 2024). 50 MCP tools, 9 lifecycle hooks, 36 cited neuroscience mechanisms (predictive coding, LTP/LTD, microglial pruning, neuromodulation, CLS consolidation), a 97-paper bibliography. Runs locally, SQLite by default, PostgreSQL + pgvector optional, no GPU. Install: /plugin marketplace add cdeust/Cortex then /plugin install cortex@cortex-plugins.
AI Architect Spec uses independent deterministic algorithms instead of LLM-as-judge polling: multi-judge consensus across specialized panels (Architecture: Liskov / Alexander / Dijkstra; Performance: Fermi / Carnot / Curie / Erlang; Security: Wu / Ibn al-Haytham; Data model: Mendeleev / DBA / Lavoisier; Acceptance: Toulmin / Popper), atomic claim decomposition, zero-LLM graph analysis with Tarjan SCC for cycles, and Phase 4 closed-loop calibration against externally-grounded falsifiers. The distribution_suspicious flag catches confirmatory bias. NFR claims never receive PASS — only SPEC-COMPLETE or NEEDS-RUNTIME.
Zetetic comes from the Greek zētēsis meaning inquiry. Zetetic AI is verification-first AI: every claim has a source (provenance), verification is deterministic not LLM-judges-LLM (algorithm > opinion), memory learns through neuroscience-backed mechanisms, and every PRD/PR/decision is auditable. AI Architect implements this standard across four independent open-source Claude Code plugins: Cortex memory, zetetic-team-subagents (97 reasoning patterns + 22 specialists), ai-architect-mcp-codebase (Rust codebase intelligence), and ai-architect-mcp-spec.
Cortex's 98.20% Recall@10 on LongMemEval-S (ICLR 2025), verified on the v4.14.3 release tree, exceeds the published paper's best retrieval result of 78.4% by +19.8 percentage points. MRR is 0.9166. The paper used 500 human-curated questions embedded in ~40 sessions of conversation history (~115k tokens). Retrieval-only metrics, no LLM reader in the evaluation loop. Cortex also achieves a 3-run mean of MRR 0.7998 / Recall@10 91.35% on LoCoMo (1,986 questions, 10 conversations). BEAM-100K MRR is 0.5417 — a within-system retrieval proxy; BEAM defines no retrieval MRR of its own (it uses LLM-as-judge nugget scoring), so we make no head-to-head BEAM claim.
97 genius reasoning agents, each citing its primary paper, plus 22 team-role specialists = 119 total. Examples: Pearl (causal inference, do-calculus), Peirce (abductive inference), Feynman (integrity & first principles), Dijkstra (correctness, structured programming), Cochrane (evidence synthesis), Curie (residual analysis), Lamport (concurrency, happens-before), Pāṇini (generative specifications), Gödel (incompleteness limits), Hamilton (priority-displaced scheduling), Taleb (fragile/robust/antifragile), Kahneman (System 1/2 debiasing), Rawls (veil of ignorance), Toulmin (argument structure), Popper (falsifiability). 64 multi-step skills, 19 lifecycle hooks, 288 passing tests. Pre-commit hook blocks UNSOURCED / MAGIC_NUMBER / TODO_NO_REF.
AI Architect Codebase is a Rust MCP server that indexes a codebase across 10 languages (Rust, Python, TypeScript, Java, Kotlin, Swift, Objective-C, C, C++, Go) into a LadybugDB property graph, resolves call chains across files, detects functional communities via Leiden-class community detection, traces processes from entry points, and builds a hybrid BM25 + sparse TF-IDF + RRF search index. 24 MCP tools across 10 stages. Read-only — never writes code, opens PRs, or runs CI. 434 passing tests, zero warnings, 45,000+ lines of Rust. Feeds Cortex (workflow graph) and ai-architect-mcp-spec (call-graph context for verified PRDs).
Each plugin ships in its own Claude Code marketplace — there is no combined monorepo install. MIT-licensed, free, install only the ones you want.

Cortex (persistent memory):
/plugin marketplace add cdeust/Cortex
/plugin install cortex@cortex-plugins
Same marketplace also carries the read-only companion: /plugin install cortex-viz@cortex-plugins

Zetetic Agents (97 reasoning patterns + 22 specialists):
/plugin marketplace add cdeust/zetetic-team-subagents
/plugin install zetetic-team-subagents

AI Architect Codebase (codebase graph + semantic search; Rust toolchain required, builds on first install):
/plugin marketplace add cdeust/ai-architect-mcp-codebase
/plugin install ai-architect-mcp-codebase

AI Architect Spec (PRD pipeline with multi-judge verification; Node 20.x or 22.x):
/plugin marketplace add cdeust/ai-architect-mcp-spec
/plugin install ai-architect-mcp-spec

All four interoperate — memory remembers, reasoning reasons, codebase maps, prd adjudicates the spec.
