ARCHITECTURE / BOUNDARIES AND AUTHORITY
Keep the source inside the answer.
Six explicit stages connect source collection, representations, hybrid retrieval and response synthesis. Deterministic validation remains a separate acceptance boundary.

INPUT / PROVENANCE
Retain the evidence origin before chunking or representation changes. Usable context and source attribution are part of the lifecycle.
RETRIEVAL / 26AI
Oracle AI Database 26AI and hybrid retrieval belong to the supplied engineering method. This public view contains no private collection or document contents.
What crosses each boundary.
01 / Source
Collect evidence and retain its origin.
02 / Chunk
Keep usable context in bounded units.
03 / Embed
Represent meaning for retrieval.
04 / Retrieve
Find relevant evidence through the available retrieval paths.
05 / Answer
Synthesize a response while retaining source attribution.
06 / Validate
Apply deterministic gates and make unresolved conditions explicit.
SYNTHESIS BOUNDARY
A fluent answer does not establish that the retrieved evidence is complete or that its claims are supported. Keep the route back to the sources.
ACCEPTANCE / VALIDATION
Apply deterministic gates and expose unresolved conditions before accepting the output. Generation and validation have different responsibilities.
PRIVATE KNOWLEDGE
The lifecycle is public; internal documents, private identifiers and the knowledge collection remain outside the portfolio.
EVIDENCE LIMIT
This conceptual provenance view does not establish current database availability, collection completeness, retrieval accuracy or physical acceptance.
