+
+`ift-ts:p2p:ift:2026q4-dst-automated-workflow`
+
+## Description
+
+Automate deployments of the latest nim-libp2p master to the Lab and execute
+basic regression tests. When results deviate from expected behavior, open an
+issue automatically in the nim-libp2p repository for triage.
+

+* owner: not assigned yet
+* status: not started
+* start-date: 2026/10/01
+* end-date: 2026/12/31
+
+#### Description
+
+Deploy the latest master revision to the Lab and trigger basic regression
+tests. Define expected outcomes and retain the tested revision, configuration,
+and results so failures can be reproduced.
+
+#### Deliverables
+
+- Automated Lab deployment and basic regression workflow
+- Documented expected results and retained run artifacts
+
+
+### Automatic Regression Issues
+
+* fully qualified name: `ift-ts:p2p:ift:2026q4-dst-automated-workflow:issue-reporting`
+* owner: not assigned yet
+* status: not started
+* start-date: 2026/10/01
+* end-date: 2026/12/31
+
+#### Description
+
+Compare regression results with expected outcomes and automatically create
+nim-libp2p issues for deviations. Include the tested revision, failing checks,
+and links to logs, and avoid repeatedly filing the same unresolved failure.
+
+#### Deliverables
+
+- Automatic issue creation for regression deviations
+- Reproducible triage details and duplicate-issue handling
+- Workflow checks demonstrating expected-result and regression-result paths

+description: Expand continuous GossipSub interoperability testing across implementations
+
+---
+
+`ift-ts:p2p:ift:2026q4-gossipsub-interop`
+
+## Description
+
+Evolve the existing GossipSub test plan into a reusable unified-testing
+framework, using [libp2p/test-plans#850](https://github.com/libp2p/test-plans/pull/850)
+as a starting point. Cover Go, Rust, JS, Python, Nim, Zig, and future
+implementations in mixed-language topologies across TCP, WebSocket, and native
+QUIC. Use unified-testing for protocol and transport debugging.
+
+Note that large-scale Shadow simulation seems to not work correctly with QUIC
+
+## Task List
+
+### Implementation And Transport Matrix
+
+* fully qualified name: `ift-ts:p2p:ift:2026q4-gossipsub-interop:matrix`
+* owner: not assigned yet
+* status: not started
+* start-date: 2026/10/01
+* end-date: 2026/12/31
+
+#### Description
+
+Build an extensible test matrix that runs mixed-language topologies and
+automatically exercises transport combinations. Ensure the framework can be
+used continuously by maintainers across implementations.
+
+#### Deliverables
+
+- Mixed-language GossipSub scenarios across the listed implementations
+- Automated TCP, WebSocket, and native QUIC combinations where supported
+- Documented workflow for adding implementations and running tests

+* status: not started
+* start-date: 2026/10/01
+* end-date: 2026/12/31
+
+#### Description
+
+Validate scoring, mesh maintenance, IHAVE/IWANT behavior, duplicate suppression,
+and consistent propagation. Run long-lived scenarios with joins, leaves,
+disconnects, reconnects, and churn, plus delayed peers, partitions, intermittent
+connectivity, and reconnect storms.
+
+#### Deliverables
+
+- Protocol behavior assertions across implementations
+- Long-running mesh stability and fault-injection scenarios
+- Reproducible failure reports for interoperability regressions
+
+
+### Metrics And Dashboard
+
+* fully qualified name: `ift-ts:p2p:ift:2026q4-gossipsub-interop:reporting`
+* owner: not assigned yet
+* status: not started
+* start-date: 2026/10/01
+* end-date: 2026/12/31
+
+#### Description
+
+Collect propagation latency, throughput, duplicate rate, and bandwidth use.
+Present standardized results so maintainers can compare releases and identify
+interoperability regressions.
+
+#### Deliverables
+
+- Comparable performance metrics from framework runs
+- Standardized dashboard with release comparisons and regression visibility

+description: Support Logos Delivery with pluggable libp2p, nim-ffi, and module API integration
+
+---
+
+`ift-ts:p2p:ift:2026q4-logos-delivery-consulting`
+
+## Description
+
+Provide consulting to Logos Delivery as they make libp2p pluggable, tracked in
+[logos-delivery#4341](https://github.com/logos-messaging/logos-delivery/issues/4341).
+Coordinate the integration with the Logos libp2p module, support nim-ffi design
+and code reviews, and help the team understand the API the module offers.
+
+This as an ongoing consulting commitment, adding specific follow-up tasks
+as requirements and priorities become clearer during Q4.

+* end-date: 2026/12/31
+
+#### Description
+
+Work with the Logos Delivery team on the interfaces and integration needs for
+pluggable libp2p. Explain the Logos libp2p module API, identify missing capabilities,
+and review opportunities to modify or simplify it based on Delivery's needs.
+
+Review nim-ffi pull requests and discuss or propose changes where needed,
+including the proposed use of polling instead of callbacks. Coordinate resulting
+API and integration decisions with Delivery and capture concrete follow-up work
+as it is agreed.
+
+#### Deliverables
+
+- Consulting and review support for the pluggable libp2p work in logos-delivery#4341
+- nim-ffi PR reviews and design feedback, including evaluation of polling instead of callbacks
+- Module API guidance and agreed changes or simplifications for Delivery integration
+- Links to reviews, decisions, and follow-up issues or PRs as work is completed

+`ift-ts:p2p:ift:2026q4-nimlibp2p-dht-publication-outcomes`
+
+## Description
+
+Make putValue results distinguish local storage from remote publication.
+Aggregate remote write acknowledgements so callers can identify successful
+peers, quorum failures, and partial or complete success. A mismatching
+acknowledgement must be reflected in the result rather than only logged.
+

+
+Define results that expose whether local storage succeeded, whether publication
+was attempted, which peers acknowledged the record, and whether the requested
+quorum was met. Specify partial success and complete failure semantics.
+
+#### Deliverables
+
+- Documented publication result types and quorum semantics
+- Caller-visible local storage, publication, and successful-peer information
+

+
+#### Description
+
+Aggregate remote write outcomes into the final putValue result. Treat mismatching
+acknowledgements as unsuccessful writes and cover local failures, no publication,
+partial acknowledgements, quorum failure, and complete success.
+
+#### Deliverables
+
+- putValue implementation reporting aggregate publication outcomes
+- Tests for mismatching acknowledgements and each result category
+- Usage examples showing how callers interpret results

+description: Negotiate the multiplexer during the security handshake
+
+---
+
+`ift-ts:p2p:ift:2026q4-nimlibp2p-early-muxer-negotiation`
+
+## Description
+
+Reduce TCP/WebSocket connection establishment by one network round trip by
+selecting the multiplexer during the security handshake. Extend the Noise
+handshake payload and connection upgrader so compatible peers can avoid the
+separate multistream-select exchange that follows the security handshake.
+
+## Task List
+
+### Handshake Negotiation And Upgrade
+
+* fully qualified name: `ift-ts:p2p:ift:2026q4-nimlibp2p-early-muxer-negotiation:implementation`
+* owner: not assigned yet
+* status: not started
+* start-date: 2026/10/01
+* end-date: 2026/12/31
+
+#### Description
+
+Add multiplexer negotiation to the Noise handshake and pass the selection to
+the muxed upgrader. Preserve the separate negotiation path when peers do not
+support early negotiation or no early selection is available.
+
+#### Deliverables
+
+- Noise payload extension and upgrader integration
+- Fallback behavior for existing peers
+- Tests for compatible peers and negotiation fallback
+
+
+### Connection Setup Validation
+
+* fully qualified name: `ift-ts:p2p:ift:2026q4-nimlibp2p-early-muxer-negotiation:validation`
+* owner: not assigned yet

+* end-date: 2026/12/31
+
+#### Description
+
+Exercise TCP and WebSocket connections with early negotiation enabled and with
+legacy peers. Verify that successful early selection removes the separate
+multiplexer negotiation round trip and establishes usable streams.
+
+#### Deliverables
+
+- Interop coverage for early and legacy negotiation paths
+- Connection traces or measurements confirming the saved round trip
