RoleStatusWhat it actually does
MENTORconectadoThe only role a normal zaynor chat/serve run actually invokes; explains an already-sealed result, never re-invokes the engine.
INVESTIGATORimplementado, sin invocación automáticaCollects a bounded evidence window and re-verifies custody hashes; real and tested, no CLI/API command calls it yet.
FLEET_COMMANDERimplementado, sin invocación automáticaWrites to the investigation log; real and tested, no caller wired yet.
DETECTION_ENGINEERimplementado, sin invocación automáticaDrafts a candidate detection rule anchored to a real sealed finding; real and tested, not wired to a command yet.
DISPATCHERimplementado, sin invocación automáticaCatalog of evidence types the engine can actually analyze; real and tested, not wired to a command yet.
ENDPOINT_HUNTER / PERSISTENCE_HUNTERout of scopeWould need a live EDR collection backend this project does not have.
THREAT_INTELout of scope, for nowA portable VirusTotal/GTI enrichment exists but is not wired in — external network dependency, pending decision.

Findings themselves come from ZAYNOR's own deterministic Mode 1 engine, not from a named agent above — no per-finding agent attribution exists in the sealed contract (AuthoritativeFinding has no agent field). This table names what ZAYNOR's own local, Ollama-driven agent layer does around that sealed result.

Methodology

The deterministic engine produces and seals the result before any language model is invoked. The model receives a compressed, read-only summary and narrates it; it cannot alter a verdict, a finding, or the seal. Every claim in a narration is checked against this sealed result before being shown (zaynor chat/serve). result_sha256 is the canonical SHA-256 seal of the authoritative result: recompute it independently with `zaynor audit` to confirm this report was not altered after the fact.
