concrete architecture map
a concrete architecture map for each vector (how you’d actually build it), then a domain-by-domain priority matrix (law, medicine, science, ops), with notes on why.
1) Vector → Concrete architectures
Vector 1 — Epistemic State Tracking (EST)
Goal: the system knows what it knows / doesn’t / can’t justify.
Architecture pattern: “Claim objects + uncertainty ledger”
-
Claim Extractor: turns model output into atomic claims (subject–predicate–object, or structured proposition).
-
Epistemic Annotator: assigns confidence, uncertainty type (missing info vs conflicting sources vs model inference), and volatility.
-
Consistency Monitor: tracks internal contradictions across claims.
-
UI Contract: output is answer + epistemic overlay (what’s solid, what’s inferred, what’s unknown).
Practical components
-
JSON schema like:
-
claim,supporting_evidence[],counter_evidence[],confidence,volatility,assumptions[],last_verified_at
-
-
Calibrators:
-
temperature-scaled confidence, disagreement-based confidence, or ensemble variance.
-
Vector 2 — Temporal Truth Modeling (TTM)
Goal: truth is time-indexed; stale knowledge is treated as stale.
Architecture pattern: “Time-versioned knowledge + freshness gating”
-
Temporal Index: store evidence as
(assertion, time_range, jurisdiction/context). -
Freshness Scorer: combines doc date, event date, and update cadence of source.
-
Temporal Reasoner: answers queries as-of time: “as of 2023” vs “current”.
-
Drift Alerts: triggers when new evidence invalidates old claims.
Practical components
-
Storage: event-sourced DB, bitemporal tables, or a knowledge graph with
valid_from/valid_to. -
Retrieval: filter by time windows + rank by recency relevance.
-
Output: “As of Dec 2025, …; prior to 2024, … changed due to …”
Vector 3 — Constraint-Based Generation (CBG)
Goal: the system can’t emit outputs that violate rules.
Architecture pattern: “Constrained decoder + validator loop”
-
Typed Output Schema: force structured outputs (forms, arguments, steps, citations).
-
Hard Validators: logic, math, policy, clinical rules, regulatory constraints.
-
Repair Loop: if invalid → request missing fields, revise, or refuse.
-
Proof/Check Artifacts: attach validator results (pass/fail + why).
Practical components
-
JSON Schema / DSLs for:
-
contracts, medication plans, scientific claims, runbooks
-
-
Validators:
-
theorem prover / rule engine (e.g., Datalog), unit consistency checker, drug–drug interaction checker, policy engine.
-
Vector 4 — Provenance-Native Cognition (PNC)
Goal: every claim has a traceable causal chain to evidence and transformations.
Architecture pattern: “Evidence graph + transformation lineage”
-
Evidence Builder: stores retrieved passages + metadata (source, author, date, jurisdiction).
-
Lineage Tracker: logs transformations (summarize → infer → aggregate).
-
Claim–Evidence Linker: maps each claim to the minimum evidence set.
-
Audit Export: machine-readable bundle for compliance / review.
Practical components
-
A “provenance graph” (nodes: evidence, claim, transform; edges: supports/derived-from).
-
Cryptographic integrity optional: hash chains for audit trails (especially ops, compliance).
Vector 5 — Drift-Aware Memory (DAM)
Goal: memory evolves safely; new info doesn’t silently overwrite old meaning.
Architecture pattern: “Belief versioning + fork + consensus”
-
Belief Store: persists claims as evolving objects.
-
Drift Detector: embedding drift + semantic drift + distribution shift detection.
-
Fork Controller: when conflict is real → branch beliefs rather than overwrite.
-
Reconciliation Layer: merges when resolved; keeps competing hypotheses when not.
Practical components
-
“Belief branches” keyed by context (jurisdiction, patient cohort, environment, time).
-
Monitoring: alert when the system’s answers change without new evidence.
Vector 6 — Model Self-Limitation Protocols (MSLP)
Goal: safe refusal and escalation is a feature, not a failure.
Architecture pattern: “Gated generation + escalation router”
-
Risk Classifier: stakes detection (medical, legal, safety-critical ops).
-
Confidence Gate: blocks completion under low epistemic confidence.
-
Escalation Router: sends to tools/humans/approved workflows.
-
Refusal With Structure: refuses with what’s needed to proceed safely.
Practical components
-
Policies like:
-
“If conflicting authoritative sources + high stakes → escalate”
-
“If missing required evidence → ask for it; do not guess”
-
-
Output templates: “I can’t answer because X; to proceed, provide Y; or consult Z.”
Vector 7 — Truth as Process, Not Artifact (TPA)
Goal: answers emerge from structured processes (debate, testing, convergence).
Architecture pattern: “Multi-agent pipeline + convergence criteria”
-
Role Agents: proposer, critic, verifier, red-team, domain specialist.
-
Convergence Engine: stops when claims reach consensus or flags irreducible disagreement.
-
Experiment/Tool Hooks: simulation, calculation, external checkers.
-
Decision Log: preserves who argued what, and why the final answer won.
Practical components
-
A workflow DAG:
-
generate candidates → 2) critique → 3) validate → 4) decide → 5) package with provenance
-
-
Scoring: agreement, validator passes, evidence coverage, novelty penalties.
2) Which vectors matter most by domain
Priority matrix (High / Medium / Lower)
| Domain | EST | TTM | CBG | PNC | DAM | MSLP | TPA |
|---|---|---|---|---|---|---|---|
| Law | High | High | High | High | Medium | High | Medium |
| Medicine | High | High | High | High | High | High | Medium |
| Science | High | Medium | High | High | Medium | Medium | High |
| Ops (IT/SRE/Sec/Prod) | Medium | High | High | High | High | High | Medium |
Why, in one line each
-
Law: provenance + time + constraints dominate (citations, jurisdictions, “as-of” validity, non-hallucinated reasoning).
-
Medicine: constraints + provenance + self-limitation are existential; drift-aware memory matters because guidelines change and populations vary.
-
Science: process (TPA) matters most—hypotheses, falsification, uncertainty; constraints for math/units; provenance for reproducibility.
-
Ops: drift-aware memory and temporal truth matter (systems change daily), plus constraints (runbooks, change control) and self-limitation (don’t brick prod).
3) Concrete “reference stacks” per domain (what I’d actually deploy)
Law stack
-
TTM + PNC + CBG + MSLP, then EST
-
Core objects: claim → jurisdiction → date → authority rank → evidence links
-
Must-have: “as-of date”, authority hierarchy (statute > regulation > case > memo), refusal when missing jurisdiction.
Medicine stack
-
CBG + MSLP + PNC + TTM + EST, then DAM
-
Validators: dosing ranges, contraindications, DDI checks, guideline version checks
-
Must-have: patient context gating; always separate “general info” vs “clinical decision support”.
Science stack
-
TPA + CBG + PNC + EST, then TTM
-
Tool hooks: calculators, simulators, unit checkers, literature consensus checks
-
Must-have: hypothesis framing, assumptions, and “what would change my mind”.
Ops stack
-
CBG + MSLP + DAM + TTM + PNC, then EST/TPA
-
Validators: runbook schema, command allowlists, environment checks, blast radius estimation
-
Must-have: change logs, rollback plans, “dry run” mode, and drift alerts when infra differs from memory.
