The streaming adapter had no onClose handling, no reconnect, and it ignored the sendBinary futures. Every later frame was thrown away while the browser still showed "recording". Each provider stream now: - sends Deepgram's KeepAlive text frame every 4 s while idle; - sends frames one at a time through a single queue, since the JDK socket rejects a send issued while another is pending, and treats a failed send as a broken stream; - on an unexpected close, error or failed send, logs a WARN with the session id and close code, then reconnects up to 3 times (0.5/1/2 s backoff). It buffers up to 30 s of audio meanwhile, dropping the oldest first, and replays it after the WhisperLive handshake; - shifts each new connection's transcript offsets by the audio that came before it, so segments stay on one timeline; - reports StreamingTranscriptionPort.Listener#onStreamLost when the attempts run out. SttStreamingWebSocketHandler then closes /ws/stt with 1011 and the client shows its error instead of a silent stall; - cancels the keepalive and any pending reconnect, and closes the provider socket, on pause, stop or client disconnect. --- CHANGELOG.md | 36 + docs/WEBSOCKET_STT.md | 31 + .../port/StreamingTranscriptionPort.java | 18 +- .../AbstractWebSocketStreamingAdapter.java | 631 ++++++++++++++++-- .../strategy/AssemblyAiStreamingAdapter.java | 7 + .../strategy/DeepgramStreamingAdapter.java | 15 + .../strategy/ExecutorStreamScheduler.java | 50 ++ .../strategy/JdkProviderConnector.java | 38 ++ .../streaming/strategy/ProviderConnector.java | 26 + .../streaming/strategy/StreamResilience.java | 38 ++ .../streaming/strategy/StreamScheduler.java | 30 + .../strategy/WhisperLiveStreamingAdapter.java | 27 +- .../stt/SttStreamingWebSocketHandler.java | 26 +- 13 files changed, 901 insertions(+), 72 deletions(-) create mode 100644 src/main/java/com/kntro/reqsai/discovery/infrastructure/ai/transcription/streaming/strategy/ExecutorStreamScheduler.java create mode 100644 src/main/java/com/kntro/reqsai/discovery/infrastructure/ai/transcription/streaming/strategy/JdkProviderConnector.java create mode 100644 src/main/java/com/kntro/reqsai/discovery/infrastructure/ai/transcription/streaming/strategy/ProviderConnector.java create mode 100644 src/main/java/com/kntro/reqsai/discovery/infrastructure/ai/transcription/streaming/strategy/StreamResilience.java create mode 100644 src/main/java/com/kntro/reqsai/discovery/infrastructure/ai/transcription/streaming/strategy/StreamScheduler.java diff --git a/CHANGELOG.md b/CHANGELOG.md index 0b86f586..42417a7e 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -11,6 +11,42 @@ follows [Semantic Versioning](https://semver.org/). _Bounded-context implementation (iam, billing, workspace, discovery, gateway) in progress._ +### Fixed (Live STT stream resilience — `bugfix/stt-stream-resilience`) + +- **Live transcription no longer stalls silently when the provider drops the stream.** In + production, a 15–20 s JVM pause meant Deepgram received no audio for over 10 s.

The tests check that: - the keepalive is scheduled, skipped while a send is pending, moved to the new connection and cancelled on close; - a provider close or error mid-session reconnects and audio continues, including audio buffered during the backoff (bounded, oldest dropped); - transcript offsets continue across a reconnect; - the WhisperLive handshake is resent; - exhausted retries report the stream lost exactly once, and a flapping provider does not loop forever; - a failed send triggers a reconnect and resends its frame, and sends never overlap; - the WebSocket handler closes the client with 1011 when the stream is lost. --- .../strategy/FakeProviderConnector.java | 68 +++ .../strategy/FakeProviderSocket.java | 161 +++++++ .../strategy/LiveStreamResilienceTest.java | 445 ++++++++++++++++++ .../strategy/ManualStreamScheduler.java | 76 +++ .../stt/SttStreamingWebSocketHandlerTest.java | 17 + 5 files changed, 767 insertions(+) create mode 100644 src/test/java/com/kntro/reqsai/discovery/infrastructure/ai/transcription/streaming/strategy/FakeProviderConnector.java create mode 100644 src/test/java/com/kntro/reqsai/discovery/infrastructure/ai/transcription/streaming/strategy/FakeProviderSocket.java create mode 100644 src/test/java/com/kntro/reqsai/discovery/infrastructure/ai/transcription/streaming/strategy/LiveStreamResilienceTest.java create mode 100644 src/test/java/com/kntro/reqsai/discovery/infrastructure/ai/transcription/streaming/strategy/ManualStreamScheduler.java diff --git a/src/test/java/com/kntro/reqsai/discovery/infrastructure/ai/transcription/streaming/strategy/FakeProviderConnector.java b/src/test/java/com/kntro/reqsai/discovery/infrastructure/ai/transcription/streaming/strategy/FakeProviderConnector.java new file mode 100644 index 00000000..f81ec6cd --- /dev/null +++ b/src/test/java/com/kntro/reqsai/discovery/infrastructure/ai/transcription/streaming/strategy/FakeProviderConnector.java @@ -0,0 +1,68 @@ +package com.kntro.reqsai.discovery.infrastructure.ai.transcription.streaming.strategy; + +import java.io.IOException; +import java.net.URI; +import java.net.http.WebSocket; +import java.util.ArrayList; +import java.util.List; +import java.util.concurrent.CompletableFuture; + +/** + * {@link ProviderConnector} that hands out {@link FakeProviderSocket}s instead of opening a network + * connection.

Subject: [PATCH 13/16] fix(discovery): turn stated business rules into stories or criteria A rule such as "si el paciente cancela con menos de veinticuatro horas, se le debe cobrar una penalidad del diez por ciento" often came out only as a clarifying question. Both extraction prompts now state that a condition with its consequence, or an obligation with its percentage, amount or deadline, is testable. It goes into "stories": as a criterion of the backlog story it governs, or as its own NEW_STORY. A question may accompany it, never replace it. An obligation that leaves the actor or amount open still gets a question. The realtime prompt also asks an UPDATE_STORY to carry only new or changed criteria and to copy unchanged fields. The language, off-topic and untrusted-transcript rules are unchanged. --- .../AbstractLlmGenerationAdapter.java | 88 ++++++++++++++++--- .../strategy/GenerationScenarioTest.java | 60 +++++++++++++ 2 files changed, 138 insertions(+), 10 deletions(-) diff --git a/src/main/java/com/kntro/reqsai/discovery/infrastructure/ai/generation/strategy/AbstractLlmGenerationAdapter.java b/src/main/java/com/kntro/reqsai/discovery/infrastructure/ai/generation/strategy/AbstractLlmGenerationAdapter.java index c240aa28..19958626 100644 --- a/src/main/java/com/kntro/reqsai/discovery/infrastructure/ai/generation/strategy/AbstractLlmGenerationAdapter.java +++ b/src/main/java/com/kntro/reqsai/discovery/infrastructure/ai/generation/strategy/AbstractLlmGenerationAdapter.java @@ -53,6 +53,59 @@ no answers to questions asked in the transcript.

Measured with + `nomic-embed-text`: the doctor's e-mail notification vs the appointment booking scored 0.88, a + cancellation vs the booking 0.85, and a synonym paraphrase of the booking 0.83. In production + (OpenAI `text-embedding-3-small`), the 10% cancellation penalty was dropped as a duplicate of the + booking. +- A draft that repeats a story and adds one clause scores like a plain restatement. Adding "… and pay + it online" to the booking scored 0.996 against it; a plain restatement of a login story scored 0.995. + +So a draft is dropped only when it is related **and adds nothing**: no new number (digits or number +words such as "diez por ciento"), no new acceptance criterion (for edge cases and updates), and no new +content word in its title, role or action. A NEW draft becomes an `UPDATE_STORY` of an accepted +story only when it is related and has the same intent (a near-identical title, or the same actor +doing the same action). Because the word checks carry the decision, changing the embedding model +does not change what counts as a duplicate. Only the relatedness bar is model-specific: re-measure +it when you switch models (the real-vector fixture in `SuggestionDedupRealVectorsTest` shows how). + +`UPDATE_STORY` suggestions carry only the acceptance criteria their target story lacks. An update +with the target's own narrative and no new criterion is dropped as noise. The realtime log line +reports these drops as `no-op-update-skipped`. + ## Tips - **Keep models warm**: Ollama unloads idle models — `OLLAMA_KEEP_ALIVE=-1` keeps them resident during a From 1d20efc72a778edba38e24b6f5167c709d0dbf87 Mon Sep 17 00:00:00 2001 From: Gutierrez Soto Jhosepmyr Orlando <jhosepmyrgutierrezsoto@gmail.com> Date: Wed, 7 Oct 2026 08:45:26 -0500 Subject: [PATCH 16/16] ci(deploy): keep the running web image when the API triggers a deploy --- .github/workflows/deploy.yml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/.github/workflows/deploy.yml b/.github/workflows/deploy.yml index 40072a97..e20ffa2a 100644 --- a/.github/workflows/deploy.yml +++ b/.github/workflows/deploy.yml @@ -24,5 +24,5 @@ jobs: echo "::notice title=Deploy not triggered::INFRA_DEPLOY_TOKEN is not set.
