Summary

Bedrock Claude requests that carry a compact_20260112 edit are now routed to InvokeModel / InvokeModelWithResponseStream with the native Anthropic Messages body, instead of the Converse API. AWS documents compaction as unsupported on Converse, which previously received the edit and silently ignored it. This fix ensures server-side compaction works on bedrock/ models, including keys that pin an inference-profile ARN.

Closes #6825

Changes

  • Routing predicate: usesAnthropicInvokePath detects a compact_20260112 edit in context_management from both the raw Params.ContextManagement field and ExtraParams["context_management"] (typed *anthropic.ContextManagement, plain map, or other JSON-marshalable value), covering the /anthropic/v1/messages ingress path that triggered the original bug.
  • InvokeModel dispatch: ChatCompletion, ChatCompletionStream, Responses, and ResponsesStream on the Bedrock provider now check the predicate before falling through to Converse, and delegate to new invokeAnthropic* methods when it matches.
  • Request body shape: AnthropicProviderRequestDefaultsMap[schemas.Bedrock] is updated to produce the InvokeModel body shape: anthropic_version: "bedrock-2023-05-31", no model field (model is in the URL), no stream field (streaming is selected by the URL), beta features via the anthropic_beta body array, and URL sources inlined. The previous Bedrock entry was a stub that only remapped tool versions; the Mantle entry is unchanged.
  • Event-stream framing: invokeEventStreamReader adapts InvokeModelWithResponseStream's AWS event-stream framing (base64-wrapped Anthropic SSE JSON inside {"bytes":...} chunk frames) to the SSEEventReader contract the shared anthropic streaming handlers consume. It is installed per request via BifrostContextKeySSEReaderFactory.
  • SigV4 signing: SignMantleV4Headers is refactored into a service-agnostic signBedrockV4Headers so the invoke path can sign for bedrock-runtime with the same mechanics.
  • Percent-encoded ARN paths: The mantleFasthttpClient (and its streaming clone) are constructed with DisablePathNormalizing: true so inference-profile ARNs in the model URL segment are not decoded and re-encoded by fasthttp, which would produce a path AWS does not recognise.
  • Compaction test coverage: RunCompactionTest is extended to run on schemas.Bedrock in addition to schemas.Anthropic, captures the outbound raw request body in both streaming and non-streaming sub-tests, and asserts via assertCompactionEgress that the body left on InvokeModel (correct anthropic_version, no model field, compact-2026-01-12 in anthropic_beta) rather than Converse.
  • Unit tests: New packages cover the routing predicate for all input shapes, the InvokeModel URL builder, the event-stream reader (happy path, exception frames, empty chunks), the InvokeModel body shape for both chat and responses builders, and the encoded-path preservation for all three fasthttp handler entry points.
  • Docs: The beta-header support table for Bedrock is updated to note that compact-2026-01-12 routes the request to InvokeModel.
  • UI: The beta badge in pageTitle.tsx receives dark-mode colour overrides.

Type of change

  • Bug fix
  • Feature
  • Refactor
  • Documentation
  • Chore/CI

Affected areas

  • Core (Go)
  • Transports (HTTP)
  • Providers/Integrations
  • Plugins
  • UI (React)
  • Docs

How to test

# Unit tests (routing predicate, event-stream reader, body shape, encoded-path preservation)
go test ./core/providers/bedrock/... ./core/providers/anthropic/...

# Integration compaction test (requires AWS credentials and a Bedrock Claude model on the compaction list)
go test ./core/... -run TestBedrock/Compaction -v

# Full suite
go test ./...

# UI
cd ui
pnpm i
pnpm build

The assertCompactionEgress helper will fail the test if the outbound body does not carry anthropic_version: "bedrock-2023-05-31" or is missing context_management, confirming the request left on InvokeModel rather than Converse.

Breaking changes

  • No

Related issues

Closes #6825

Security considerations

SigV4 signing is reused unchanged; the refactor only parameterises the service name. No new secrets, auth flows, or PII handling are introduced.

Checklist

  • I read docs/contributing/README.md and followed the guidelines
  • I added/updated tests where appropriate
  • I updated documentation where needed
  • I verified builds succeed (Go and UI)
  • I verified the CI pipeline passes locally if applicable

Walkthrough

Bedrock Claude requests with compact_20260112 now use native Anthropic InvokeModel APIs. The change adds request shaping, streaming adaptation, encoded-path preservation, classified error handling, regression tests, documentation updates, and unrelated beta badge styling.

Changes

Bedrock compaction support

Layer / File(s) Summary
InvokeModel request contracts
core/providers/anthropic/requestbuilder.go, core/providers/bedrock/mantle.go
Bedrock InvokeModel requests now use the required Anthropic body fields, tool mappings, beta headers, URL-source inlining, and signed wire content.
Routing and streaming handlers
core/providers/bedrock/bedrock.go
Claude requests with compaction edits use InvokeModel or InvokeModelWithResponseStream. Other requests retain Converse routing. AWS EventStream frames are adapted to Anthropic events.
Stream error and fallback handling
core/providers/utils/utils.go, core/utils.go, core/utils_test.go
Classified stream errors retain their status and retry behavior. Fallback clears the Bedrock EventStream reader factory.
Routing and wire-format validation
core/providers/bedrock/*_test.go, core/providers/anthropic/*_test.go, core/internal/llmtests/compaction.go, tests/e2e/api/collections/provider-harness.json
Tests cover routing, payload fields, encoded inference-profile paths, EventStream conversion, raw egress requests, fallback cleanup, and Bedrock compaction scenarios.

Prompt cache documentation

Layer / File(s) Summary
Cache breakpoint guidance
docs/providers/supported-providers/anthropic.mdx
The documentation describes automatic cache-breakpoint injection and related configuration and override references.

Beta badge styling

Layer / File(s) Summary
Dark-mode badge styling
ui/components/pageTitle.tsx
The beta badge adds dark-mode green border and background classes. Its label and rendering behavior remain unchanged.

Estimated code review effort: 4 (Complex) | ~60 minutes

Severity of issue fixed: High

[Bug]: Bedrock provider silently drops Anthropic compaction (compact_20260112) — capability matrix says supported, but Claude egress is Converse-only
