docs(mosaic): add sign-in and sign-up next-step design - #10733
Adds the design for how sign-in and sign-up report their next step (packages/mosaic/docs/internals/sign-in-sign-up-flow.md).
Each sign-in and sign-up has a typed next step (first_factor, second_factor, fields, verify_email, …). Clients derive the screen from it instead of rebuilding the flow from status, missing_fields and unverified_fields. Decided for clients; the FAPI side (FAPI sending next_step, FAPI-owned transfer) is a proposal to the FAPI team.
The getNextStep bridge the doc describes is in a stacked PR on carp/signup-next-step-bridge.
Checklist
pnpm test runs as expected.
pnpm build runs as expected.
(If applicable) JSDoc comments have been added or updated for any package exports
The pull request adds a design document for FAPI-derived sign-in and sign-up steps. It describes step-to-route mappings, navigation behavior, entry actions, transfer rules, API-version handling, and rollout phases. It also updates controller guidance to state that these flows derive screens from next-step helpers while retaining route-specific state locally. The changeset file gains two horizontal rules.
clerk/javascript#10742: Implements the next-step helpers and bridge described in the design.
clerk/javascript#10727: Structures sign-in views around step values, matching the design’s step-driven screen selection.
clerk/javascript#10691: Revises controller guidance for multi-step flows, which this change extends with sign-in and sign-up guidance.

Merge Risk: Moderate · up to 39772
This adds a design document and no runtime behavior. If the phase-1 implementation follows the document as written, completed sign-ins would not activate sessions and transferable attempts would only be re-routed. Ticket redemption would also be under-specified. Clarify these points in the design before building on it.

New sign-up returns start
An uncreated sign-up's Future resource still reports missing_requirements, so the bridge returns unknown, not start; the new Entry actions section, which runs tickets on the start screen, inherits this.

- Line 35: Update the sign-up example around signUp.update to check and display
its returned error before routing, and apply the same handling to the sign-in
example so failed updates do not continue to the switch.
- Around line 66-67: Update the sign-up flow around getSignUpNextStep and the
screen selection so the initial route and reset explicitly show the fields
screen before sign-up requirements are available. Preserve the existing
next-step behavior once sign-up has started, and do not rely on the bridge’s
unknown result for the initial state.
- Line 71: Move the FAPI-owned step exception from the sign-in/sign-up flow
guidance into the multi-step flow section of Controllers, where it qualifies the
rule that the machine owns the step. Link to that controller guidance from this
paragraph, preserving the explanation that FAPI-owned steps should not be
duplicated in machine state.

- Around line 101-115: Update the next-step logic for `SignUpNextStepInput` so
an unverified `web3_wallet` produces the supported wallet verification step
instead of falling through to `{ type: 'unknown' }`. Reuse the established step
shape and wallet verification state; do not invent a new step type or
verification API.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Guard the in-flight redemption.
A “not redeemed yet” check remains true while the first request is pending. A StrictMode effect rerun or remount can therefore start a second redemption before the first completes. One request can then fail after the other consumes the ticket. Specify a synchronous in-flight guard that survives remounts, and release it on failure so the user can retry.

Handle email-link return status before routing by step.
An expired or client-mismatch return needs an error state. A link verified on another device needs a switch-tab state. Routing only by the sign-up step can skip those states. Specify how the entry action handles each return before continuing the flow; emailLinkVerification alone does not cover returns without a created session ID.

Preserve sign-up metadata when redeeming a ticket.
If implemented as specified, the callback omits configured unsafeMetadata. The legacy flow passes it to sign-up, so the new flow can lose metadata intended for the user. Read the ticket in the model and pass both values to signUp.ticket().

A ticket is single-use, so the guard is "not redeemed yet", not "first mount". A bare mount effect runs twice under React StrictMode and again on remount. Mosaic has no shared helper for this yet; the first feature that needs one adds it to `src/hooks/`.

Define a phase-1 fallback for per-target sends.
When a user switches to another email or phone with the same strategy, the bridge reports the first target’s sent state for the second target. The new flow can then ask for a code that was never sent. Define a client-side send or resend path for this case rather than waiting for FAPI to add per-target state.

The route decides what shows. The step decides which routes are usable and where to go after a submit. Two pure functions in the feature hold the tables above:
-`routeFor(step)`: the step's route.
-`allowedRoute(route, step)`: `true` for `start`, for the step's own route, and for `continue` while sign-up verifies, so the user can edit a field.

Description
Adds the design for how sign-in and sign-up report their next step (
packages/mosaic/docs/internals/sign-in-sign-up-flow.md).Each sign-in and sign-up has a typed next step (
first_factor,second_factor,fields,verify_email, …). Clients derive the screen from it instead of rebuilding the flow fromstatus,missing_fieldsandunverified_fields. Decided for clients; the FAPI side (FAPI sendingnext_step, FAPI-owned transfer) is a proposal to the FAPI team.The
getNextStepbridge the doc describes is in a stacked PR oncarp/signup-next-step-bridge.Checklist
