Target-state architecture for the agentic enterprise
Seven planes across fourteen layers.
The components, protocols, control points, and contested choices, with the evidence behind each and the refusals stated plainly. Built for the architects who will design it, and written so that everyone who will live with it can follow: every page opens in plain terms, and every technical word explains itself.

Enforcement and evidence must remain outside the agent’s influence.
Six things every design must get right.
Each one cuts across every layer of the estate. Get these right and the layer-by-layer choices become ordinary engineering.
The four deterministic zones
The identity and delegation chain
Enforcement outside the model
The data-to-memory pipeline
The learning flywheel
The autonomy contract
What you already own, and what changes in each part.
Fourteen deep pages. Each one states the target state, the mechanisms, the contested choices with verdicts, the cross-cutting concerns, and where the evidence runs out.
We ran the experiments. Here is what held.
Five rounds on public corpora with human relevance judgements, seeded and reproducible to the byte. The multi-vector result held, the purpose-view result held under one condition, and the idea the programme was built to prove did not survive. All of it is published, with the reversals.
How we caught our own errorsOne vector per document
0.815 to 0.294
nDCG@10 as a document grows from one aspect to ten. The single-vector index collapses.
Purpose views, aspect-targeted queries
+0.188
Over matched chunks at ten aspects per document, with 25 percent fewer embeddings.
Purpose views, whole-document queries
−0.032
Below matched chunks on human-judged scientific abstracts. The boundary of the method.
Objective conditioning
0 of 5
Forms of telling the index the goal that survived testing, including real human-judged data.
Verdicts, sources, and gaps stated as gaps.
Evidence status on every claim
Verdicts, not surveys
