Answer wait: show the sources arriving, and pace them - #2450
Conversation
The rail that shows retrieval's sources during the wait has been built since PR #2437 but invisible: both #100 Phase 1 flags shipped default-off, so the whole wait was a status line and three prose bars. Turn both on. Server emission (RAG_INCREMENTAL_EVIDENCE_PREVIEW) defaults true; the client gate renders unless the value is the literal string "false". Rollback order is unchanged - emission first, then rendering, which is inlined at build time and needs a rebuild. Two defects surfaced while proving the render path, both invisible while the flags were off: - The status line printed the unit's source count, up to twelve, above a rail capped at six. The line's whole contract is that the reader can count its number on screen, so it now reads the rail's cap from one exported place. - The rail shared `.stagger-item`'s 35ms rung, so six cards arrived in 175ms as one movement. Scoped to 90ms, declared unlayered next to the rule it overrides because a layered override loses to it whatever its specificity. And the browser proof #100 has been waiting for: two Chromium journeys drive a stream carrying a real evidence_preview unit and assert the sources are readable during generation, capped at six, counted correctly, ordered line/prose/rail, handed over to the answer's own numbered rail on arrival, paced apart with motion allowed, and simply present with motion suppressed. Retrieval, ranking, selection and the final payload are untouched; no file under src/lib/rag/ is edited.

The rail's 90ms literal tripped the design-system contract's hardcoded-CSS-duration ratchet. A stagger interval is not a duration rung — the ladder times an item's own entrance, these time the gap between entrances — so it gets its own named pair rather than being forced onto --duration-*, and the base rule's existing 35ms literal moves onto the same scale. Hardcoded CSS durations: 26 -> 25. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FhZWF4Bj4LwpPeW82tDfd4

`Production UI (3)` failed twice on this branch at
tests/ui-specifiers.spec.ts:451 with
Locator: getByRole('heading', { name: 'Add episode features' })
Expected: focused Error: element(s) not found
I previously reported this as not caused by this change. That was wrong,
and the PR comment saying so is corrected in the thread. Main's CI run on
3b6e73c — the exact commit this branch merged as its base — has
`Production UI (3)` and `PR required` both green (run 33113246111), so the
failure tracks this branch, not the base.
Root cause is a hydration race that has always been latent here. `gotoApp`
in this spec waits only for `#main-content` to be visible, which is the
server-rendered shell; it does not wait for React to attach handlers. The
step advance is a plain `onClick` on the primary Button, so a click landing
before hydration is silently dropped, the step never changes, and the
step-2 heading the assertion looks for is never rendered — reported as
"element(s) not found" rather than "not focused", which is exactly the
signature seen. Nothing in this diff reaches /specifiers/builder; what it
does change is the client bundle both flags now include, and that moves
hydration timing on every route enough to lose a race that was already
being run.
Fix uses the probe this repository already uses for the same problem in
ui-smoke.spec.ts and ui-stress.spec.ts: poll the element's `__reactProps$`
until the handler is a function, then click. Applied at both
"Continue to features" clicks in this file — the failing reduced-motion
and forced-colors journey, and the copyable-diagnosis journey above it,
which runs the identical unguarded pattern.
No test is skipped, quarantined or weakened; both assertions still run in
full.
Verified locally against a production build on this head:
tests/ui-specifiers.spec.ts — 12 passed (25.6s); typecheck exit 0;
prettier reports the file unchanged.

…ironment
CodeRabbit finding on this PR, verified and correct. The unset case calls
`incrementalEvidencePreviewRenderingEnabled(undefined)`, which falls
through to the default parameter and reads
`NEXT_PUBLIC_RAG_INCREMENTAL_EVIDENCE_PREVIEW_RENDER`. So the assertion
did not pin the documented default at all — it reported whatever the
runner's environment happened to hold, and would go red on any shell
exporting the documented rollback value.
Reproduced before fixing. With `NEXT_PUBLIC_RAG_INCREMENTAL_EVIDENCE_PREVIEW_RENDER=false`
in the environment, the previous test fails:
AssertionError: expected false to be true
Tests 1 failed | 6 passed (7)
The variable is now stubbed away for the assertion and restored after,
using `vi.stubEnv` / `vi.unstubAllEnvs` as elsewhere in this suite, with
an explicit check that it really is unset. The no-argument call is
asserted alongside the explicit `undefined` one, since that is the shape
production code uses. The explicit "true" and "false" assertions are
unchanged.
Same command after the fix:
Test Files 1 passed (1)
Tests 7 passed (7)
typecheck exit 0; eslint clean on the file; prettier reports it unchanged.

trimSourceForClientpolicy the final payload uses; it rides the existingprogressevent as an optional field, so no new stream event name is introduced and an old client ignores it. The stream boundary still rejects any unit failingisDeliverableVerifiedUnit. What changes is when already-permitted source content reaches the screen, not what may reach it.RAG_INCREMENTAL_EVIDENCE_PREVIEW=falseto stop the server emitting the unit at all; then setNEXT_PUBLIC_RAG_INCREMENTAL_EVIDENCE_PREVIEW_RENDER=falseand rebuild, since that value is inlined at build time. No schema or stored-data rollback is involved.false, that overrides the new code default, and the client one must be corrected before a rebuild for the rail to appear on the live site.Clinical Governance Preflight
Required:
scripts/pr-policy.mjsclassifies this PR as clinical-risk because the prebuild regeneratesdata/outstanding-issues-snapshot.json, which sits under the clinical-dataset path (the known friction recorded as#Y090R5). The checklist is answered on its merits regardless, since the change does alter when source content reaches a clinician's screen.Source-backed claims still require linked source verification before clinical use
The preview is explicitly not an answer. Its cards carry a dot rather than a number, its accessible name reads "not yet numbered — the answer decides the final list", and the surface never marks the answer complete. Every card links to the exact page the passage came from. Numbering is what arrival buys.
No patient-identifiable document workflow was introduced or expanded without explicit governance approval
No new data source, no new workflow, no change to document access or owner scope.
Supabase target remains
Clinical KB Database(sjrfecxgysukkwxsowpy)No Supabase file, migration, or environment value is touched.
Service-role keys and private document access remain server-only
The unit crosses the route boundary only through
trimSourceForClient, the same bounded field set the final payload already permits, andisDeliverableVerifiedUnitstill rejects anything outside it.check:client-bundle-secretspassed inside the production build.Demo/synthetic content remains clearly separated from real clinical sources
Sample-document mode is untouched and still returns without emitting a preview.
Source metadata, review status, and outdated/unknown-source behavior remain conservative
Each card shows freshness through
sourceStatusShortLabel, the same helper the arrived answer's rail uses, so the wait and the answer can never disagree about a document's status. Any danger-level source-governance warning suppresses the entire preview — stricter than the final response's own refusal, because at preview time the answer's support level is not yet known.Deployment classification/TGA SaMD impact was checked when clinical decision-support behavior changed
The design doc's SaMD disposition holds: this changes presentation timing, not intended purpose or recommendation logic. Reassessment is required before Phase 2, which remains unbuilt.
Notes
Opened as a draft. Merging to
maindeploys to production automatically, so the timing of that merge is the owner's call.Generated by Claude Code
Note
Low Risk
Preview content is already governance-gated and unchanged in retrieval/ranking; risk is mainly presentation timing and flag defaults, with a two-step env rollback if needed.
Overview
Enables #100 Phase 1 by default so governed source cards show during the answer wait, not only when the final answer lands. Server emission
RAG_INCREMENTAL_EVIDENCE_PREVIEWnow defaults totrueinsrc/lib/env.ts; the client gate insrc/lib/client-env.tsrenders the rail unlessNEXT_PUBLIC_RAG_INCREMENTAL_EVIDENCE_PREVIEW_RENDERis the literal string"false". Rollback order is documented: turn off server emission first, then the build-time client flag.Aligns the wait status line with what’s on screen. The progress message now counts sources using the same six-card cap as
AnswerEvidencePreview(visiblePreviewSourceLimit), so a unit with up to twelve sources cannot print “8 sources found” above six cards.Paces preview cards separately from other cascades. Shared stagger timing moves to
--stagger-cascade(35ms) and--stagger-cascade-wide(90ms);.answer-sources-arriving .stagger-itemuses the wide rung via an unlayered override so six cards read as separate arrivals while skeleton bars and result grids keep the default interval. Reduced-motion rules still force immediate full opacity.Closes the browser proof gap with Playwright journeys (sources visible during generation, handoff to the numbered answer rail, stagger vs suppressed motion) plus CSS/DOM contract tests and updated design/env docs.
