Fix-in-lane for the two Task-4 review findings, red-first TDD, inside the
existing nine-file fence.
M-A: the composer now filters model <option>s to the intentionally selected
provider (harness.providerId). With no provider chosen the model select offers
only its placeholder, so a user can never pick a model that belongs to a
different provider.
M-B: the model <option> value is now the collision-safe composite
`${providerId}:${modelId}` (was the bare modelId), the controlled select value
mirrors that same identity so the exact catalog row highlights, and the change
handler resolves the composite back to the exact catalog row and persists that
row's own {harnessId, providerId, modelId}. selectModel(providerId, modelId) no
longer combines a bare model id with ambient provider state, so two providers
exposing the same modelId stay distinct.
New red-first tests prove: cross-provider models absent, identical modelIds
under two providers stay distinct and resolve to the intended tuple, a provider
change invalidates the old model and keeps send disabled until the new tuple
persists, and a model pick does not enable send until its exact PUT resolves.
The four existing anti-masking invariants and the 422 tuple-preservation test
are intact.

Add the Slice-Zero catalog and selection HTTP surfaces for P3 Task 3:
GET /api/harnesses, GET /api/harnesses/:harnessId/catalog,
GET+PUT /api/chat/preferences/selection. Scope is always server-derived
via scopeFromUser(CurrentUser); selection tuples are validated against the
live catalog with no fallback substitution and persisted in a transitional
owner-scoped in-memory store. HarnessModule is wired into AppModule.

root cause: emitDecoratorMetadata reflected the third constructor parameter as Function and Nest attempted to resolve it
fix: optional HANDOFF_ID_FACTORY injection token, no production provider, preserving undefined -> crypto.randomUUID() default and unchanged positional construction
TDD: real CoordModule red at Function index [2], then green; test overrides only unrelated AuthGuard because its AUTH provider comes from AppModule's global AuthModule context
Closes#1145
Bring the chat experience into the Vite/React-Router SPA on the exact typed
Socket.IO /chat contract from @mosaicstack/types, replacing the /chat
placeholder behind AuthGuard. Surfaces message:ack (with an accessible
status), agent:start, streamed agent:text/agent:thinking, tool start/end
status, agent:end with usage, session:info (thinking controls + routing
decision), commands:manifest, command:result, command:approval (with a
one-time approved-run affordance), system:reload (refreshing the rendered
manifest), and error, and emits message/abort/set:thinking/command:execute/
command:approve with exact payloads.
The gateway does not guarantee message:ack is the first event for a new
conversation (session:info, and error on auth/session-creation failure, can
both arrive first) — conversation-scoped events now adopt the conversation
from whichever scoped event names it first while a send is pending, then
filter everything else against that established conversation. A typed error
stops streaming instead of leaving Stop stuck active; agent:end no longer
appends an empty assistant turn when there is no text or thinking; and a
second message can no longer be sent while a turn is streaming.
Command approval is now integrity-checked end to end: only one
command:approve request may be outstanding at a time (a concurrent request
is ignored rather than overwriting the pending command/args), a stale or
mismatched command:approval response cannot replace active approval state,
and running an approved command clears its approval state immediately (via
a ref, before React re-renders) so a double-click cannot replay
command:execute.
The `/chat` socket is now typed at a single boundary: apps/web/src/lib/
socket.ts narrows socket.io-client's untyped `io()` return value to
`ChatSocket` (Socket<ServerToClientEvents, ClientToServerEvents>) once, at
creation, via the one assertion the library's types force; every consumer
(use-chat-connection.ts) then gets fully checked `on`/`emit` calls with no
further casts. The shared contract types live in the new
apps/web/src/lib/chat-contract.ts (replacing the old spa/chat/types.ts
shim), which re-exports them via type-only imports resolved directly
against packages/types/src (apps/web has no @mosaicstack/types package
dependency, so this stays source-only and is erased at compile time —
no package manifest or lockfile is touched). The two recorded-event test
suites now drive a shared, typed fake socket
(spa/chat/test-support/fake-chat-socket.ts) instead of an untyped
`(event: string, payload: unknown)` harness, so a wrong event name or
malformed payload fails to compile.
First increment of the approved Phase P RFC (webui-mission). Adds a Vite + React
Router SPA scaffold coexisting with the Next app: index.html with the theme
anti-flash script, src/main.tsx entry, the v1 parity route table under Guest/Auth
guard shells, and a dev proxy (/api, /socket.io ws) to the gateway on 14242 so the
SPA is same-origin in dev. vitest bumped to v3 (vite 8 pairing); existing specs
pass unchanged. Next remains the served app until the P5 cutover.

CaService hard-requires STEP_CA_URL/provisioner config at construction, so an
unconditional FederationModule import makes every standalone/local boot die at
DI time. Gate the module on loadConfig().tier === federated, matching the
documented intent of the federation compose profile (must not start in
non-federated dev).
Verified in mosaic-dev box: standalone tier boots to "Gateway listening on
port 14242" with bootstrap/socket.io/auth surfaces responding; federated tier
path unchanged.
