m's 14:56 observation: long Paliadin turns showed "Verbindung verloren —
Antwort wird nachgereicht …" but never delivered. The aichat backend
finished the turn upstream; paliad's HTTP client had given up at 130 s
and the legacy filesystem janitor never ran for the aichat path.
Three intertwined fixes, all shipped together because they share the
same wire shape and the same UI states:
1. Switch the aichat backend to /chat/turn/stream
- new AichatPaliadinService.RunTurnStream relays incremental chunks
- SSE parser handles default `data:` frames (chunk/meta/done/error)
and named `event: heartbeat` frames per the upstream contract
- no more 130 s hard ceiling — stream stays open as long as data or
heartbeats flow; silenceTimeout (90 s) catches a true upstream
stall instead
2. Proof-of-life thinking events
- handler emits `event: thinking` every 5 s while the upstream is
silent (synthesised locally) AND relays aichat's `heartbeat`
events as thinking pings
- frontend renders a lime-dot pulse + monospace counter inside the
assistant bubble — the user can SEE the chat is still working
3. Honest disconnect copy + real late-recovery
- new dispatching endpoint GET /api/paliadin/turns/{id}/recover
- aichat backend: asks aichat via GET /chat/conversations and
/chat/conversations/{id}/turns whether the turn actually finished
- legacy backend: falls through to the local row read (janitor)
- frontend swaps "wird nachgereicht" → "Lade frische Antwort …"
while the recovery polls; on confirmed "lost" swaps to
"Antwort konnte nicht zugestellt werden — bitte erneut stellen"
- migration 118 adds aichat_conversation_id to paliadin_turns so
the recovery has a fast path when the done frame arrived before
the drop
Streaming + recovery are a no-op for PALIADIN_BACKEND=legacy: the
StreamingPaliadin interface is detected via type assertion, the
LocalPaliadinService stays on the one-shot RunTurn + filesystem
janitor path.
13 new unit tests cover the SSE parser, the conversation-API client,
and the match-assistant-response helper.
go build ./... + go test ./internal/... + go test ./cmd/server/...
+ bun run build all clean.
