# FLUID-WP-0004 - Publication and control APIs

Nothing reaches the router unsigned. The deterministic policy gate is built now,
before anything can generate candidates, so a future Daimon has nowhere to
bypass.

## T01 - Publication pipeline

```task
id: FLUID-WP-0004-T01
status: todo
priority: high
state_hub_task_id: "74bf29c7-b8a6-5a18-bfc7-94641d12564b"
```

Blueprint §35: SOURCE, BUILD, CONTRACT CHECK, TEST, SECURITY CHECK, POLICY
CHECK, SIGN, PUBLISH, ROUTE. Each stage emits an audit event.

## T02 - Descriptor signing and verification

```task
id: FLUID-WP-0004-T02
status: todo
priority: high
state_hub_task_id: "9449aa0b-3c73-56d5-8768-df94b26f0282"
```

The router accepts only signed or otherwise authenticated published revision
descriptors (§35). An unsigned descriptor must be refused, and that refusal
tested.

## T03 - Revision API

```task
id: FLUID-WP-0004-T03
status: todo
priority: high
state_hub_task_id: "ba302369-3243-57ac-a34a-9a0a29002ac5"
```

Blueprint §44.1: create, verify, publish, set state, query lineage.

## T04 - Intent API

```task
id: FLUID-WP-0004-T04
status: todo
priority: medium
state_hub_task_id: "27c597da-4f58-5a0d-b70e-8ba0749d9002"
```

Blueprint §44.5: read active intent, read historical intent, validate a
candidate against intent, propose an amendment. Amendment stays separately
governed — the API records a proposal, it does not enact one.

## T05 - Deterministic policy gate

```task
id: FLUID-WP-0004-T05
status: todo
priority: high
state_hub_task_id: "b2f96c6c-2c37-5892-bafd-ab9eb2c3f8c2"
```

Blueprint §28.2. Allowed adaptation class, permitted operational mode,
complexity threshold, security status, test status, compatibility status,
traffic-allocation maximum, budget, approval requirement. This gate is the
architectural boundary that stops agentic reasoning from becoming security
policy.

## T06 - Trust model in the type system

```task
id: FLUID-WP-0004-T06
status: todo
priority: medium
state_hub_task_id: "70cc234b-9570-5c51-8620-1a7d32b9a25c"
```

Blueprint §47 made mechanical: generated artifacts are an untrusted candidate
type until verification produces a signed revision. The compiler should make the
unsafe path awkward to write.
