Architecture
One decision layer across the procurement lifecycle.
Six layers. Control does not simply follow reasoning — it constrains it, and gates what reaches a decision. Every layer below is a real boundary in how a decision is produced, not a marketing diagram drawn after the fact.
INPUT LAYER
Raw procurement documents enter the system. Nothing here is treated as structured until the evidence layer has processed it — see Tender Intelligence.
EVIDENCE LAYER
Deterministic, evidence-first extraction. Every finding carries a reference back to the exact source passage — missing evidence is reported as unresolved, never assumed.
REASONING LAYER
Landed-cost, margin and feasibility reasoning over structured evidence — see Commercial Analysis.
CONTROL LAYER
The control layer does not evaluate after the fact — it constrains what the reasoning layer is allowed to conclude. See Principles.
DECISION LAYER
Exactly three outcomes exist. An unrecognized action class resolves to denial, never to a default allow.
AUDIT LAYER
Collects the evidence and decision path produced by every outcome above — direct or escalated.
Decision provenance
Every decision should answer four questions.
What evidence supported it?
What finding was derived?
What rule was applied?
Who or what had authority to approve it?
Brisora is designed around decision provenance rather than black-box output.
Material decisions can be reconstructed from the evidence and rules that produced them.
Why determinism
Identical inputs produce identical decision semantics.
There is no model sampling in the decision path. Extraction is deterministic, evidence-first pattern matching, validated against real public tender documentation — not general-purpose, unqualified document AI. The reasoning and control layers evaluate the same evidence the same way every time, so a decision can be re-run and re-checked rather than merely trusted.

Tender intelligence is the input layer above, in detail — from document to structured, evidence-anchored finding.
