The #347 auto-seed worked (the greeting was in the session ledger at seq-0),
but the web UI never showed it: there was no GET /api/sessions/{id}/messages
route and startSession() went straight from create to persona/tools/admin
hydration, so the transcript only filled from the live turn stream + user
echoes — a seeded turn-0 was invisible.
- server: new proxy route GET /api/sessions/{id}/messages -> get_session_messages
(mirrors the tools/bifrost proxies; status-preserving envelope).
- SPA: loadTranscript(sessionId) fetches it on open and renders existing turns
(assistant -> .response .md-body via markdownSafe escape-first; user ->
.prompt-echo via textContent), called after the workspace opens. Best-effort.
web_debug_surface contract amended (endpoint + loadTranscript). 2 web route
tests, suite 617 green. Playwright DOM check proved the render end-to-end
(drive the real UI -> Sindra's greeting bubble appears).
