FLUID-WP-0006 - FLUID Science

Hypotheses, experiments, fitness and promotion. Entirely human-driven — the Daimon is deliberately absent. Blueprint §50 says the success criterion is proving this loop works cleanly and safely, not autonomous coding.

T01 - Hypothesis records and lifecycle

id: FLUID-WP-0006-T01
status: todo
priority: high

Schema doc §2: DRAFT, READY, PRIORITIZED, DESIGNING, EXPERIMENTING, EVALUATING, then ACCEPTED, REJECTED, SUPERSEDED or DEFERRED. Keep observation, explanation, prediction, intervention and result separate — schema doc §18 warns that collapsing them into one narrative destroys criticism and auditability.

T02 - Competition groups

id: FLUID-WP-0006-T02
status: todo
priority: medium

Rival explanations of one pressure coexist (schema doc §6). Preserving uncertainty is a feature.

T03 - Hypothesis API

id: FLUID-WP-0006-T03
status: todo
priority: medium

Blueprint §44.3: create, compare, prioritize, attach candidate, record outcome.

T04 - Experiment controller

id: FLUID-WP-0006-T04
status: todo
priority: high

Blueprint §16. Declares hypothesis, control, candidate, cohorts, allocation, metrics, guardrails, start and stop conditions, maximum duration. Per §17 it must not touch traffic directly: it writes routing policy the router consumes. Experiments are interruptible.

T05 - Experiment API

id: FLUID-WP-0006-T05
status: todo
priority: medium

Blueprint §44.4: create, start, change bounded allocation, stop, record metrics, finalize.

T06 - Fitness evaluation against hypotheses

id: FLUID-WP-0006-T06
status: todo
priority: high

Wire the fitness engine to experiments. Success criteria may not be changed after results are visible without recording the amendment (§18).

T07 - Promotion controller

id: FLUID-WP-0006-T07
status: todo
priority: high

PROMOTE, EXPAND_EXPERIMENT, RETAIN_AS_OPTION, MODIFY, REVERT, ABANDON, DEFER recorded as decisions with an authorizing actor (§19). Human authority only.

T08 - Append-only event log

id: FLUID-WP-0006-T08
status: todo
priority: high

Every transition above as a fluid_event (schema doc §15). FLUID evolution is itself a system behavior that must remain reconstructable.

T09 - Audit trace command

id: FLUID-WP-0006-T09
status: todo
priority: high

fluid audit trace <revision> reconstructs pressure, hypothesis, revision, experiment, fitness and decision, answering all eleven questions in API Standards §25.
