The gateway can now enforce a revision's declared contract, which makes
"a deterministic API contract" -- the first minimal-conformance
requirement -- something the framework actually checks rather than
assumes.
The JSON Schema support is a documented subset. Keywords outside it are
reported as unsupported rather than skipped, because a validator that
silently ignores a constraint it does not understand is worse than none:
it reports success it did not earn. The same reasoning refuses remote
$refs, which would make request-path validation depend on a network
fetch, and refuses to serve a revision whose contract is not registered.
String lengths are counted in runes. A 4096-character limit that
rejected a 3000-character hall entry because of its accents would be
wrong in exactly the case this framework was built to publish.
Literal routes are matched before templated ones, so /entries/latest is
not swallowed by /entries/{id} -- which matters, since a latest-entry
convenience route is the Blueprint's own worked example.

Completes FLUID-WP-0006. The loop now runs end to end from the command
line: two competing presentation hypotheses, an experiment that issues a
routing policy rather than touching traffic, an amendment, a stop that
returns traffic to the default, a confirmed outcome, a resolved
competition, and a promotion the gate can refuse.
Starting or stopping an experiment returns the routing policy for the
operator to install rather than installing it. Blueprint 17 keeps the
controller out of the traffic path, and installing from the handler
would put it straight back in; emitting the document keeps the
separation visible instead of implied.
`fluid audit trace` now answers the section 25 questions from events
rather than summary records, and names the rivals a hypothesis beat: an
audit asking which hypotheses were considered is not answered by naming
only the winner.
Two fixes found by driving the CLI rather than only the tests. Go's flag
package stops at the first positional, so ids given after flags silently
swallowed them; ids are now taken before parsing. And there was no way
to attach a revision to the hypothesis that produced it, which left
`audit trace` unable to say why a revision existed -- `hypothesis attach`
closes that.

Completes FLUID-WP-0005. Normalization and redaction live on one path,
shared by the in-process emitter and the ingest endpoint: two paths with
two normalizations would eventually disagree, and the disagreement would
surface as a pressure finding that is really a pipeline bug.
Telemetry kind is inferred from event shape rather than defaulting to
"request", since an error filed as a request understates the interface's
failure rate. A malformed event in a batch does not discard the rest.
Feedback is stored as evidence and creates no pressure and no hypothesis
on its own, per API Standards 15, with the consumer recorded as the
actor so their untrusted status stays visible in the audit trail. The
feedback endpoint is the only consumer-reachable part of the control
plane.
The observation endpoints are not served at all when no pseudonymization
salt is configured, rather than served with a generated one: a salt that
changed per run would make the same consumer look new every time and
every cohort count wrong.
Adds an end-to-end test driving real traffic through the gateway and
confirming it becomes a classified pressure record, with no raw consumer
identity reaching the store.

Completes FLUID-WP-0004. The Revision and Intent APIs (Blueprint 44.1
and 44.5) are served by fluid-control, which is deliberately off the
request path and must never be reachable by interface consumers: it is
the mechanism that evolves the interface in response to their behaviour.
Intent amendment is a proposal, never an edit. Rewriting a recorded
version returns 409, because changing what a version says would change
what already-published revisions were governed by.
A rejected candidate comes back as 422 with its full stage report rather
than as a server fault. Rejection is a normal outcome (invariant 14) and
the reasons are the evidence a later hypothesis needs.
Also closes a real hole this workplan opened: `fluid revision publish`
previously wrote straight into the evidence store, which was a way
around the deterministic policy gate for anyone with shell access. It
now runs the same pipeline the control plane does and requires a signing
key.

Completes FLUID-WP-0003. The evidence store is append-only at the
database, not by convention in Go: a trigger blocks UPDATE and DELETE on
fluid_events in both SQLite and Postgres, so the guarantee binds a psql
session and the CLI equally, not just callers who go through the Go API.
Records are derived summary state and may be superseded; the event log
stays the authority.
The intent store makes a recorded version immutable and content
addressed, since reassigning what governed a revision after the fact
would break the one audit question Blueprint 27 exists to answer. The
unfilled InterfaceEvolutionIntent template is rejected rather than
defaulted, because a template still listing every FLUID-N mode has not
been completed and defaulting it would pick a permissive authority by
accident.
The CLI reads the evidence store directly rather than through the
control-plane API, so an operator can reconstruct history when the
control plane is down.

Completes the request path for FLUID-WP-0003 T01-T03 and T05-T07. The
gateway resolves a revision, routes to the adapter process, and records
what happened, without ever depending on the control plane to serve.
Three behaviours carry tests because the architecture rests on them:
Emit never blocks against a stalled sink (Blueprint 34.2), the gateway
keeps serving after control-plane loss (invariant 2), and backend
internals do not leak into error responses (5.7).
The connector retries only idempotent methods, so a slow adapter cannot
cause a hall-of-helix entry to be published twice, and breakers are
per-revision so a broken candidate does not take the stable revision
down with it.

Completes FLUID-WP-0002. The record types in internal/contract are
generated from schemas/ by a dependency-free generator; fixtures
transcribed from the spec's worked examples validate against those
schemas and round-trip through the generated types with
DisallowUnknownFields, so a spec change that misses the schemas fails
CI rather than drifting silently.
Adds identifier prefix helpers, Makefile, GitHub Actions, and five ADRs
recording the Go choice, out-of-process attachment, the wire contract as
boundary, the evidence store, and revision identity.
