Log a dropped event instead of continuing silently.

When sonic.Marshal fails, the loop skips the event with no log line. If the skipped event is the terminal done or error frame, the stream ends with no terminal frame, and the client cannot tell success from failure.

Log the failure, and emit a terminal error frame when the skipped event was terminal.

Avoid mutating the caller's slice during trimming.

append(messages[:1], ...) writes into the backing array of the input slice. The copy is safe today because the destination indices always trail the source indices, and the caller passes a freshly unmarshalled slice. The behavior depends on both facts and breaks quietly if either changes.

Build a new slice instead.

 	if len(messages) > odinMaxHistoryMessages {
 		// Trim from the front, keeping the first turn. The opening question
 		// usually carries the framing everything after it depends on, so dropping

Bound the computed budget.

budget is maxIterations * EffectiveRequestTimeoutSeconds() seconds. validateOdinConfigInput in transports/bifrost-http/handlers/odin.go rejects a negative request_timeout_seconds but sets no upper bound. max_iterations reaches schemas.OdinMaxIterationsCeiling. A large stored timeout therefore holds an SSE connection open for a very long period, and an extreme value overflows the time.Duration multiplication.

Clamp the budget to a maximum, or add an upper bound to request_timeout_seconds validation.

around response.Usage and preserve the existing output contract. In
docs/openapi/schemas/management/odin.yaml lines 191-197, retain the “whole

agent.

In `@transports/bifrost-http/handlers/odinclient.go`:
- Around line 149-155: Update the old-instance replacement logic around
current.Swap and previous.client.Shutdown so active requests are allowed to
complete within one request budget before teardown, or revise the nearby comment
to accurately state that shutdown cancels in-flight work; preserve the existing
replacement behavior and avoid implying graceful completion unless the
implementation enforces it.
- Around line 138-144: Update the bifrost.Init call in the Odin client setup to
use a server-scoped context rather than the per-request ctx, so the cached
instance is not canceled by request termination. Remove the nearby comment
claiming that in-flight requests finish during Shutdown, since shutdown cancels
the instance context and aborts them.
- Around line 40-61: Update odinAccount.GetKeysForProvider to resolve
a.config.APIKeyID through the deployment’s provider-key pool and copy the
referenced key’s Value into the returned key.Value, rather than wrapping the ID
with NewSecretVar. Preserve the empty-APIKeyID behavior and keep the returned
key ID usable for Odin routing.

57-57: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Replace the undefined default constants.

schemas.WarpDefaultMaxIterations and schemas.WarpDefaultRequestTimeoutSeconds are not exported by the resolved core module; core/schemas/warp.go names them only in doc comments. golangci-lint reports undefined: schemas.WarpDefaultMaxIterations here. The framework/warp test package does not compile, so all Warp tests in this cohort stop running.

Derive the expectation from the accessors the production code uses.

🐛 Proposed fix
-	expected := time.Duration(schemas.WarpDefaultMaxIterations*schemas.WarpDefaultRequestTimeoutSeconds) * time.Second
+	expected := time.Duration(defaults.EffectiveMaxIterations()*defaults.EffectiveRequestTimeoutSeconds()) * time.Second

164-172: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Schedule retirement using the retired instance's own grace.

instanceFor computes the delay from config, which belongs to the replacement instance. A turn already running on previous was budgeted from the previous config. If an operator saves a smaller MaxIterations or RequestTimeoutSeconds, the new grace is shorter than that turn's Turn.Budget, and Shutdown cancels the old Bifrost context while the turn is still running.

Store the grace on clientInstance when it is built, then use the stored value when scheduling the shutdown.

🛠️ Proposed fix
 type clientInstance struct {
 	client *bifrost.Bifrost
 	// signature identifies the config the instance was built from, so a settings
 	// save that did not touch the model does not tear down a working client.
 	signature string
+	// grace is the retirement delay derived from this instance's own config, so a
+	// later replacement with a shorter budget cannot cut a running turn short.
+	grace time.Duration
 }
-	previous := c.current.Swap(&clientInstance{client: client, signature: signature})
+	previous := c.current.Swap(&clientInstance{
+		client:    client,
+		signature: signature,
+		grace:     retirementGrace(config),
+	})
 	if previous != nil {
-		time.AfterFunc(retirementGrace(config), previous.client.Shutdown)
+		time.AfterFunc(previous.grace, previous.client.Shutdown)
 	}

- Around line 405-420: The addUsage function currently merges only scalar token
counters, causing later Warp chat turns to lose nested token details and cost
data. Replace its manual merge logic with schemas.MergeBifrostLLMUsage(total,
turn), while preserving the existing nil handling and cumulative EventDone.Usage
behavior.

In `@transports/bifrost-http/handlers/warp.go`:
- Around line 54-56: Update WarpHandler.RegisterRoutes to register
/api/warp/chat unconditionally, and have the chat handler return HTTP 503 with
the appropriate schemas.WarpUnavailableReason when h.service.CanChat() is false.
Update BifrostHTTPServer.ReloadPlugin and the Warp service/handler lifecycle so
a logging-plugin reload rebinds or recreates the service with the current log
manager, allowing the endpoint to become usable after logging is enabled.

no-log-store behavior into the 503 response description, and remove or restate

by syntheticToolCallID(iteration, i) is stored in a local variable and its

Ensure the reader is cleared after removal so Warp no longer retains or serves

🟠 Major · Shut down Warp when Serve returns an error. · server.go:3245-3252

transports/bifrost-http/server/server.go:3245-3252
🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Shut down Warp when Serve returns an error.

The errChan branch closes other resources and returns the error without calling s.WarpHandler.Shutdown(). The dedicated Warp service and its worker pool can remain active.

Move shared cleanup into one helper, or shut down WarpHandler before returning from this branch.

POST /api/warp/chat: the tool-calling loop, its SSE and buffered transports, and
Warp's own model client. Also adds doc comments across the Warp Go files.

The loop emits events onto a channel rather than writing SSE directly, so the
streaming and non-streaming endpoints share one implementation and the loop is
testable without a socket. stream selects the transport, not the behaviour.

Two failure-mode decisions, both tested:

An error frame is terminal and never followed by done, including when the
iteration cap is hit. A client keyed on done would otherwise read a failed
request as a successful one with a short answer.

A failing tool is reported back to the model as a tool result rather than
aborting the request. A bad filter name is recoverable - the model reads the
error and retries - and aborting would turn that into a dead end.

Warp runs a dedicated Bifrost instance rather than the gateway's shared client.
The deciding reason is self-pollution: the gateway client runs the logging
plugin, so Warp's own calls would be written into the very table Warp reads, and
asking 'how many requests today' twice would give different answers. BaseURL
being account-level and governance budgets throttling the dashboard are the other
two. The cost is that Warp's spend is invisible to gateway logs, so usage is
reported on the done event.

The context snapshot is the security-critical part. fasthttp recycles RequestCtx
once the handler returns and the agent goroutine outlives it, while
queryscope.FromContext treats a missing scope as no restriction - so a dropped
scope would silently return every row in the deployment with nothing erroring.
snapshotWarpContext lifts the scope out before the goroutine starts.

Client-supplied system turns are rejected: they would let a caller displace the
instructions that keep Warp from inventing numbers.

Fixes an ordering bug in this stack: Bootstrap constructs WarpService before
plugins load, so the nil guard in RegisterAPIRoutes would have skipped attaching
the log manager and the chat route would never have registered.

The system prompt tells Warp to name Bifrost rather than "the gateway". Bifrost
is the product the person asking runs; naming the category instead reads like
Warp is describing someone else's system.

Warp's account passes the stored key reference through as the key value. With
the default base URL that reference reaches this Bifrost, which resolves it
against its own key pool and substitutes the real credential - so Warp never
holds one.

Guards nil message content. ChatMessage.Content is a pointer and providers leave
it nil on a turn that is purely tool calls - which is the most common shape in
this loop, since Warp's first move is almost always a tool call. Dereferencing
it panicked, and because the loop runs in a goroutine that panic took the whole
server down rather than failing one request. Two tests cover it: a tool-only
turn and a final turn, both with nil content.

Warp now admits what it cannot answer. Its tools cover traffic, not
configuration, cluster state, guardrails or routing - and asked about one of
those it was reporting traffic statistics instead, which is worse than saying
nothing because it looks like an answer and is read as one. The prompt now
requires saying so in one sentence, stopping, and offering a GitHub issue link
so the gap can be reported.

The link is offered only for things genuinely out of reach: an empty result is a
real answer, not an unanswerable question, and conflating them would train
people to file tickets for their own typos.
