Summary

Brings the engine's common track to the published A2A-T SDK 1.1.0 and restructures the engine around an explicit host-callback contract. 49 commits; all carry DCO signoff.

Key changes

  • SDK 1.1.0 from Maven Central (377973d): drops the pinned unreleased local build (1.0.0-0de5a27) and the CI steps that built it; the engine now consumes the published release directly.
  • Protocol traffic observability (f8acfc0): ObservedHttpClient / WireGrpcInterceptor / WireLog observe the wire at the application boundary after SDK serialization, with redaction guarantees covered by dedicated tests.
  • Host-callback architecture (47005e9): replaces the extension-handler plugin machinery (ExtensionRegistry / TaskTHandler / NegotiationTHandler / A2ATContentFacade / TaskDispatcher) with the ControlPoint callback contract — the engine owns DAG scheduling, the A2A envelope, auth, transport, and task waiting; the host owns message content, schemas, templates, and semantic validation (BusinessInput / TaskResult / NegotiationReply / RouteRequest model layer). Transport state and business content are now mapped independently (ProtocolResultAdapter, FailureMapping).
  • Samples aligned with SDK 1.1.0 (c34d8d3): authorization and negotiation flows follow the current typed APIs and the caller-owned NegotiationContext.
  • Docs (ad205f4, e8794f4): business-callback integration contract (en + zh), refreshed SPN integration guidance, and the canonical Negotiation-T extension URI fix.

Earlier commits in this batch

The remaining commits cover the previously-reviewed incremental track: reusable credential profiles, external AgentCard loading, pre-workflow failure isolation, wire-protocol lifecycle hardening, and the corresponding docs/tests.

Test plan

  • mvn clean verify on the full reactor — 268/268 tests green
  • Direct-OMC SPN demo E2E (embedded OMCs, offline LLM provider) — two overlapping city diagnoses, one merge, negotiation rounds, notification closure, clean shutdown
  • Unit suites for the wire-observation layer (redaction included) and the callback boundary
  • No vendor SDK types in common modules; Order adapter remains dev-only and is not part of this PR

feat(engine): adapt to latest A2A-T SDK content APIs and negotiation …
d1ca753 
…contract

- adopt TemplateUri/StandardTemplates value types on all prompt-generation calls
- rename to validateProposePromptAndDataFilling with explicit NegotiationContext param
- add A2ATContentFacade: full SDK content-layer surface (generation x8, state
  machine x3, validate x4, template queries x4) exposed on A2ATransport
- expose template queries on WorkflowEngineClient (getPrompts/getNegotiationPrompts/getPrompt)
- inject business negotiation param schema via config (engine core stays domain-agnostic)
- negotiation auto-loop: Accept/Reject/Abort terminal rendering via SDK templates,
  round-exhaustion abort flow, rendered follow-up message body (was placeholder)
- fix SSE hang on INPUT_REQUIRED: read propose text+metadata from status message,
  merge status-message metadata into response extraction
- stop re-triggering negotiation on completed replies carrying business results
- constant-ize engine-internal negotiation metadata keys
- refactor autoNegotiate into sub-50-line methods, drop dead code

feat(samples): SDK negotiation content integration for SPN scenario
4436fb6 
- render Negotiation-T propose via SDK templates (negotiationType/buildProposeContent/
  proposeTemplateUri subclass extension points, three negotiation types)
- send propose as INPUT_REQUIRED status message (standalone agent Message closes
  the SSE stream per a2a-java SDK spec behavior)
- validate-and-fill follow-ups with explicit NegotiationContext from metadata;
  render Accept and attach to the result artifact metadata
- SDK-driven needsNegotiation via validateTaskPromptAndDataFilling (blank slot triggers)
- server-side validate full set: validateAuth/validateNotification with compliance fallback
- NegotiationStrategy: structured Accept payload per SDK scenario data (drop legacy
  in-text context extraction removed from templates)
- A2ATProtocolCases demo reproducing the 11 protocol verification cases + template query case
- negotiation E2E integration test (negotiation auto-loop completes over real SSE)
- fix Negotiation-T extension URI casing in agent cards (NEGOTIATION-T -> Negotiation-T/v1)

refactor(samples): remove redundant demo code and deduplicate shared …
ed17eec 
…logic

- delete TransportWorkbenchAgentExecutor: no callers anywhere, only
  Javadoc references (the Spring-managed SpringWorkbenchExecutor is
  the sole workbench executor)
- extract SpnCasePrompts: the ~600-char Task-T private-line complaint
  prompt was hardcoded identically in SpringSpnDemo and three times in
  A2ATProtocolCases; now defined once with well-formed / blank-object /
  unknown-port variants per spec cases 7.1/7.3/7.4
- extract OmcAgentLauncher: the load-agentcard -> resolve-bind-address
  -> start-server boilerplate was duplicated in SpringSpnDemo,
  A2ATProtocolCases and both integration tests
- SpringSpnDemo: only start the HTTP mock gateway (26400) in mock mode;
  order mode routes through the Eastcom Order SDK and its bundled
  protocol simulator (26401), so the 26400 instance sat idle
- update DESIGN-NOTES.md and notification-t-design-analysis.md to the
  current class names

Verified: mvn verify all green (23 samples tests); SpringSpnDemo runs
end-to-end in direct, mock and order+simulator modes; A2ATProtocolCases
case 7.1 completes.

refactor(samples): move SpringWorkbenchExecutor to the workbench package
0b2eea8 
The workbench executor lives with the orchestration it drives. This
restores a clean layering: agents/ now contains only the OMC-side
executors (zero cross-package dependencies), workbench/ is
self-contained, and the agents -> workbench / agents -> gateway
dependency edges disappear.

Update the Javadoc reference in SpringWorkbenchApplication, the class
table in the SpringSpnDemo call-chain doc (also fixes several stale
pre-reorg paths) and the DESIGN-NOTES structure diagram.

Verified: mvn test all green (23 samples tests); SpringSpnDemo
direct mode runs end-to-end.

feat(engine): full A2A-T SDK integration — fromData dual track and th…
53ec6f0 
…e stateful negotiation loop

Close the gaps found in the SDK-usage audit; the engine now exercises
the SDK's full surface per the official demo patterns instead of
degrading to fallback paths.

fromData dual track (E1):
- WorkflowEngineClient.sendMessageFromData(agent, message, data,
  schema, templateUri): deterministic Task-T rendering via
  generateTaskPromptFromDataWithSchema (no scenario recognition, no
  LLM); travels through the a2at.taskData/taskSchema/taskTemplate
  metadata keys consumed by TaskTHandler
- ExtensionSender.sendExtensionMessageFromData: same track for
  Authorization-T / Notification-T pre-positioning
- A2ATContentFacade exposes generateTask/Auth/NotificationFromData

Stateful negotiation loop (E2) — the auto-loop previously degraded on
every round ('must be a string: negotiationType', 'No negotiation
context', 'Unsupported negotiation type'):
- agent propose now carries the startNegotiation payload's context in
  the negotiation_context metadata key (SDK demo convention)
- NegotiationTHandler reads negotiation_context first, hands the raw
  context map to receiveNegotiation, and validates the full propose
  text (not the short parts placeholder) through
  validateProposePromptAndDataFilling
- context synthesis covers both context shapes (raw map and
  receiveNegotiation result) for follow-up rendering
- requires the SDK client-handler fix (a2a-t-sdk-java
  fix/client-negotiation-handlers) to fully run

Follow-up dual track (E3): 'data:{json}' clarification prefix renders
the Accept deterministically via generateAcceptFromData; reject:/abort:
and plain-text (fromText) paths unchanged

Demo passes original data (D1): SpnCasePrompts now holds the raw
complaint fields + schema; SpringSpnDemo and A2ATProtocolCases send
data through the fromData track, letting the SDK render the Task-T
prompt (577 chars via Task-T/private-line-complaint/v1) instead of
hardcoding the rendered prompt text.

Verified: mvn verify all green (105+5+23 tests); SpringSpnDemo
end-to-end in direct/mock/order modes with the full SDK negotiation
chain logged (propose fromData -> receiveNegotiation ->
validatePropose extracted params -> generateAcceptFromText); protocol
case 7.1 completes.

feat(samples): southbound fromData dispatch, fromData pre-positioning…
bc36988 
…, template fixes

Complete the dual-track rollout to every remaining send path and fix the
template mismatches found in the sweep:

- WorkbenchControlPoint.onTask: southbound workbench->OMC task dispatch
  now goes through sendMessageFromData with city-scoped data (city1 =
  blank slots to trigger negotiation, city2 = complete complaint); the
  hand-built City1/City2 Task-T prompt strings are gone
- WorkflowEngineClient.sendMessageFromData gains the extraMetadata
  overload (workbench passes the empty Negotiation-T key to activate the
  extension header alongside the data track)
- ExtensionPrePositioner: Authorization-T / Notification-T pre-positioning
  now renders via sendExtensionMessageFromData /
  sendNotificationFromData with typed policy/subscription data and
  schemas mirroring the bundled SDK slot schemas
- ExtensionSender.sendNotificationFromData implemented (event callback
  preserved; shared stream-open path extracted)
- Template fixes: Notification-T default is SERVICE_RECOVERY (service
  recovery event), not SUBSCRIBE_INCIDENT (incident subscription) — the
  wrong template was rendering the recovery subscription against the
  incident template; agent-side validate schema aligned to the
  service-recovery slots (drop the non-existent 通知主题 slot)
- TaskTHandler: negotiation-follow-up skip now requires a NON-EMPTY
  Negotiation-T value (an empty value only activates the extension
  header on the first send and must not skip fromData rendering);
  engine-internal a2at.taskData keys are stripped on that path so they
  never reach the wire
- advanceStateMachine: the continueNegotiation context is surfaced as
  the top-level negotiation_context key so the agent-side parser finds
  a full stateful map on the follow-up
- NegotiationBaseAgentExecutor.parseNegotiationContext: same fallback
  chain as the engine side (negotiationContext -> negotiation_context,
  both raw and receive-result shapes)

Verified: mvn verify all green; direct and order demos end-to-end with
ZERO degradation warnings — the full chain runs the SDK path: fromData
Task-T render (city1+city2), stateful propose, receiveNegotiation,
validatePropose extracted [id, round, maxRounds, 接入端口名称, 投诉分类],
SDK Accept render on both sides.

refactor(engine): migrate off the SDK's deprecated negotiation state …
2d56c27 
…machine

Per upstream review (a2a-t-sdk-java PR #138): negotiation/{types, store,
runtime, handler} is deprecated demo-era code slated for removal; the
current architecture is content/ + generation/ + resources/ + validation/
exposed via NegotiationContentService. The engine now uses only current
APIs — when the SDK deletes the deprecated packages, nothing here breaks.

Migration (the content layer is stateless by design — session identity
and round tracking stay with the caller, SDK guide §1.10):

- A2ATContentFacade: drop the startNegotiation / receiveNegotiation /
  continueNegotiation pass-throughs; add contextPayload/contextFromMap —
  the engine's serialization of the session context ({id, round,
  maxRounds}) for the negotiation_context metadata key (with legacy
  state-machine-format tolerance in the parser)
- NegotiationTHandler.afterReceive: no receiveNegotiation call — the
  INPUT_REQUIRED task state plus the propose text in metadata already
  signal the pending negotiation; the engine answers directly and
  validates the propose through the current
  validateProposePromptAndDataFilling
- DefaultWorkflowEngineClient.advanceStateMachine: replace the SDK state
  machine with engine-held rounds (core.model.NegotiationContext.
  nextRound(); terminal on reject/abort), re-serialized into
  negotiation_context; drop the NegotiationPayloadMapper /
  types.model dependencies entirely
- samples NegotiationBaseAgentExecutor: agent-owned session context
  (UUID + round 1 + DEFAULT_MAX_ROUNDS) serialized into the propose
  metadata instead of server.startNegotiation; negotiationType()
  extension point replaced by proposeTemplateUri() (the template URI
  encodes the type — no deprecated enum needed)
- NegotiationUtils.negotiationResponseMetadata takes the context map
  directly (no startNegotiation payload extraction)

Verified against clean trunk SDK (823f76a, PR #136 included): mvn verify
all green (105+5+23); direct/order demos end-to-end with the full
negotiation chain on current APIs — propose context (id/round/maxRounds)
→ validatePropose extracted params → engine Context advanced round 1->2
→ SDK accept rendering; A2ATProtocolCases case 7.1 completes.

feat(a2at): adopt SDK 1.0.0-841c575 typed negotiation and task dispatch
1dcb86e 
Pin the A2A-T SDK to revision 841c575 and migrate the engine onto its
current APIs:

- NegotiationContext now carries a mandatory performative; context
  parsing rejects malformed or performative-less wire contexts
- Replace the clarification control-string contract (data:/reject:/
  abort: prefixes) with the typed NegotiationDecision model routed to
  the exact SDK fromText/fromData method; abortData validates the
  termination reason before invoking the SDK
- Introduce NegotiationRequest as the typed business view of an
  INPUT_REQUIRED negotiation, carrying session/round/performative and
  the propose template kind
- Introduce TaskDispatcher and TaskSubmission so business callbacks
  dispatch natural-language or structured Task-T input without
  manipulating protocol metadata
- Update samples and bilingual docs to the typed APIs
