FLUID-WP-0004 T01, T02, T05, T06. The pipeline is the only path from
Candidate to Verified: no other code constructs a Verified value, and
Publish takes one, so "AI-generated artifacts are untrusted until
verified" is a property of the type signatures rather than a rule people
are asked to remember.
The policy gate is a pure function of the candidate, the governing
intent and configured limits. It cannot consult a model or take an
opinion as input, because a gate that can be argued with is not a gate.
Two behaviours it enforces are worth naming: the tighter of the
descriptor's own traffic ceiling and the gate's wins, so a descriptor
can restrict itself but never widen; and a daimon cannot authorize its
own promotion below FLUID-5, since generation authority is not promotion
authority.
Signatures cover the canonical document with the signature member
removed, so a signed descriptor round-trips and a tampered one does not.
The registry now refuses anything that does not verify, which is what
makes the pipeline's signature mean something at the router.
An unchecked pipeline stage is recorded as unchecked rather than
omitted, so a pipeline with no security check cannot look identical to
one that passed.

The registry is a cached snapshot rather than a control-plane client, so
the data plane keeps serving when the control plane dies (Blueprint
34.6). Routing policy generations are monotonic: a delayed older policy
is refused rather than silently rolling back an in-flight experiment's
allocation.
The resolver implements the Blueprint 5.2 precedence chain and records
why each revision was chosen. Experiment allocation is a deterministic
function of a sticky key namespaced by experiment id, so a consumer
stays in one arm for the experiment's duration and does not land in the
same arm of every concurrent experiment.
