Topic	Discussion	Notes
Agenda Review	Kevin pasted the agenda into the chat and pinned it, inviting additions and prioritization.	Agenda pinned to chat. Items may be postponed until next week.
Committee Election Outcome	Tex, the TSC secretary, confirmed the re-election of Kevin and the election of Ryan, Udai, Leandro (Leo), and Seung to the committee for the next year.	Congratulations to the newly elected members. Tex sent welcome emails and will help coordinate the transition.
Transition Plan	Kevin emphasized the need to manage the transition between outgoing and incoming members to ensure continuity. The initial step is adding all new members to the relevant Slack channels.	Ensure all incoming members (Leo and Udai confirmed requests) have access to TSC Slack channels.
Thanks to Outgoing Members	Kevin expressed gratitude to the outgoing members for their fantastic contributions over the past year.	Kevin acknowledged and thanked outgoing members for their diligent service.
Intersect Annual Report Request	The TSC was asked to prepare an annual report for presentation by Intersect next week. Kevin asked all members who served last year to provide input.	Annual Report is due very quickly (possibly by Friday/Monday). Requires input from all members who served.
Report Drafting Strategy	Kevin offered to create the first draft in a shared drive by the next day, but requested that members review his initial list of major points to identify any omissions.	Kevin will create a draft document in the shared drive by tomorrow. Tex will share an example report from the product committee.
Volunteer for Report Summary	Sebastian volunteered to take ownership of compiling the final summary of the report, suggesting the use of language models for summarization and focusing on notable points.	Sebastian will compile the report. Tex will help provide access to relevant meeting minutes/notes. Target first report is by end of tomorrow.
Nested Transactions Concerns	Micheel presented his technical concerns regarding nested transactions, arguing they add complexity to the ledger without solving any problems that can't be handled by normal transactions.	Michele cited concerns about added complexity, difficulty in developer tooling/interface, and potential for Value Extraction (MEV) due to signature changes.
Nested Transactions: Atomicity	Neil, Duncan, and Michele debated the core value of nested transactions. Neil and Duncan argued the key is providing atomicity with separate signing, which Michael asserted could be achieved differently.	The core technical dispute is whether nested transactions add unique atomic functionality beyond what is currently possible with normal transactions and off-chain coordination.
Next Steps for Nested Transactions	Kevin proposed that Michele summarize his concerns in a few sentences to organize a focused discussion involving TSC members and the Ledger Working Group for an adjudication of the issues.	Michael to send a summary of concerns to Kevin or Tex. A follow-up discussion with the Ledger Working Group will be organized.
Appeal: Repository Ownership	Neil clarified Marcin's request: the appeal is for IOSIM and Type Protocols repositories to be owned by Intersect instead of IOG. This is primarily to allow non-IOG natural maintainers to be added, ensuring wider participation and continuity.	Marcin confirmed that the repositories are core components of the Ouroboros network/Cardano node and should be under Intersect for better ecosystem support.
OSC Discussion & Scope	Tex noted that the OSC would also be discussing this appeal the next day. Tex also raised a broader issue of setting rules for what is considered relevant for Intersect ownership.	The issue will be discussed by the OSC tomorrow. Sebastian made a case for adopting repos that offer maintainer access for the Cardano node supply chain.
Repository Ownership Vote	The TSC voted on a motion to support the adoption of IOSIM and Type Protocols within the Intersect organization due to their role as dependencies of the Haskell node.	Vote Carried (8 Yes, 0 No). Tex will record the outcome and convey it to the OSC. Duncan (abstaining) noted a colleague applying for maintainership.
Impending Governance Shutdown	Kevin raised the critical issue of the Cardano Atlantic Council resigning from the Constitutional Committee (CC), which will drop the CC size below the minimum of seven, freezing all governance actions (treasury withdrawals, hard forks, parameter updates).	Intersect is holding a snap election to replace the member. Members were encouraged to consider standing individually or collectively as CC members.
