+# Voice S2S Second PoC Decision Memo
+
+Date: 2026-06-26
+
+## Decision Boundary
+
+The primary voice architecture remains cascade-first:
+
+```text
+browser audio -> WSS -> STT transcript -> engine -> TTS audio -> browser
+```
+
+This memo does not approve or reject a second s2s PoC. It defines the evidence
+needed before that decision is made. The dashboard decision item remains a human
+decision, because choosing s2s affects auditability, dataset quality, latency,
+cost, and the user experience.
+
+## Current Position
+
+- Cascade is the Phase 1/2 baseline because transcript is a first-class artifact
+  for review, safety checks, audit, cost attribution, and recursive-learning
+  export.
+- S2S is no longer rejected only because of transcript loss. Realtime stacks may
+  expose transcription hooks, so the actual question is whether s2s can preserve
+  the same evidence contract while improving immersion or latency.
+- A second s2s PoC is valid only as a bounded comparison against the cascade
+  path, not as a replacement by assumption.
+
+## Evidence Required To Keep S2S
+
+S2S stays on the roadmap only if a PoC can prove all of the following:
+
+| Area | Required proof |
+|---|---|
+| Transcript | Final transcript is persisted with timestamps and turn boundaries. |
+| Safety | Crisis/safety classifiers receive the same or stronger text signal as cascade. |
+| Review | Learner review and supervisor review can cite exact utterance text. |
+| Audit | Provider, model, token/audio cost, latency, and failure mode are logged per turn. |
+| Latency | Median user-perceived round trip is meaningfully better than cascade on the same network. |
+| Barge-in | Interruptions produce deterministic logs and do not corrupt transcript order. |
+| Failure | STT/TTS/model failures do not save partial learner-only turns as completed dialogue. |
+| Privacy | Browser receives no bearer token; any realtime credential is short-lived and session-scoped. |
+
+## Evidence That Rejects S2S
+
+S2S should be dropped for this release if any of these hold after the PoC:
+
+- Transcript is missing, delayed beyond review usefulness, or cannot be aligned
+  to turn boundaries.
+- Safety classifiers see weaker input than the cascade transcript path.
+- The provider path requires browser-visible long-lived credentials.
+- Cost or latency is worse without a clear user-experience gain.
+- Failure recovery creates ambiguous persisted turns.
+- The PoC requires special-case review/export logic that forks the data model.
+
+## PoC Shape
+
+Minimum acceptable comparison:
+
+1. Use the same P1 persona, same counselor prompt, and same scripted learner
+   utterance set for cascade and s2s.
+2. Record TTFT, full round-trip latency, transcript finalization time, cost, and
+   failure events for at least 20 short turns.
+3. Export a side-by-side report with transcript equality/coverage, safety input,
+   and persisted turn metadata.
+4. Keep cascade as production default until the report satisfies every required
+   proof above.
+
+## Dashboard Mapping
+
+- `s2s 2차 PoC 판단`: this memo satisfies the artifact requirement.
+- `s2s 2차 PoC 채택 여부`: remains `DECIDE` until the comparison report exists
+  and the project owner chooses keep/drop.
