Module gate 

Gate-decision policy over an already-computed warble::BlastRadius (Phase 4a — the mutating guardrail described in blast-radius.md §6). Pure, no I/O: the host computes the radius (via crate::blast_radius_for_project), then this module turns it plus a threshold into a decision the host can act on (allow the apply, escalate to human approval, or hard-block it).

Structs

GateThreshold

The thresholds a gate decision is evaluated against. All fields are optional: an absent max_severity/max_downstream simply never triggers that branch of the policy.

Enums

GateDecision

The outcome of a gate decision — what the host should do with the pending mutating apply.

Functions

decide

Pure policy over an already-computed radius. Returns the decision plus a human-readable reason (surfaced to the operator / logged, not machine-parsed).

parse_severity

Parse a warble::Severity from its human-readable name (the inverse of severity_str). Case-insensitive; returns None for anything else (the caller should reject an unknown flag value rather than silently defaulting).

severity_str

Human-readable name for a warble::Severity (the inverse of parse_severity).
