…nterop spec Implements three orchestration improvements: **VeriMAP per-subtask verification predicates (#2269)** - Add `verify_predicate: Option<VerifyPredicate>` and `predicate_outcome: Option<PredicateOutcome>` to `TaskGraph` nodes (`#[serde(default)]`, backward-compatible) - Predicate gate in `dag::ready_tasks()`: blocks downstream dispatch until predicate resolves; failure triggers replan via dedicated `max_predicate_replans` budget (separate from `max_replans`) - `SchedulerAction::VerifyPredicate` emitted idempotently each tick; in-flight dedup via HashSet - `LlmPlanner` prompt updated to emit `verify_criteria` alongside `task_description` - `ContentSanitizer` threaded into `PredicateEvaluator` to prevent prompt injection - `tokio::time::timeout` wraps every predicate LLM call (`predicate_timeout_secs`, default 30s) - New config fields: `verify_predicate_enabled`, `max_predicate_replans`, `predicate_provider`, `predicate_timeout_secs` **Error cascade abort defense (#2407)** - New `lineage.rs` module: `ErrorLineage`, `LineageEntry`, `LineageKind`, `classify_error` - `CascadeDetector::evaluate_abort()` returns `AbortDecision`; new `cascade_failure_rate_abort_threshold` - `DagScheduler::lineage_chains: HashMap<TaskId, ErrorLineage>` side-table (mirrors `cascade_detector`) - Cascade abort on N consecutive chain errors: `OrchestrationError::CascadeAborted { root, chain }` - Lineage entries pruned on task Completed + TTL-based retain on Failed insertion - `inject_tasks()` resets lineage for affected tasks - New config fields: `cascade_chain_threshold` (default 3), `cascade_failure_rate_abort_threshold` (default 0.0, opt-in), `lineage_ttl_secs` **Agent interoperability protocol gap analysis (#2307)** - New `specs/045-interop-protocol-gaps/spec.md`: capability matrix for MCP, ACP, A2A, ANP including capability re-negotiation row; protocol selection guidance; ANP deferred as P4 - Addendums to `specs/013-acp/spec.md` and `specs/014-a2a/spec.md` with positioning notes - ACP 0.11.x capability re-negotiation marked Unverified; P3 follow-up documented in spec Closes #2269, #2407, #2307. NOTE: LLM serialization gate required before merge — PR touches LlmPlanner prompt assembly and new `chat_typed::<EvalResponse>` path. Run live API session test per CLAUDE.md rules.
