Module: Insika::Context::Priority

Defined in:

lib/insika/context/priority.rb

Overview

Precedence ladder for context fragments — SINGLE SOURCE of the order (trust boundary). Higher = more authority: appears earlier in the system prompt and survives budget cuts. Providers reference these constants instead of loose numbers, so the boundary is an auditable contract in a single place (trust_boundary_spec locks the order).

Contract: identity and guardrails go PINNED at the top; TURN injections (request_context — the consumer's tenant/vars) sit at the BOTTOM and are sacrificed FIRST under budget. Identity (pinned) is NEVER truncated. A prompt injection riding in via turn data is DATA, not authority — it does not override IDENTITY/SOUL, and security decisions (tool allow/deny, egress, approvals) live in the engine/profile, never in the injected block.
