ADR-099: Int64/Uint64 as first-class kinds. The POC targets (SFTP offset: u64, metatensor data_offsets: u64) require 64-bit integers. The prior Uint64 addition was removed because it was half-finished; this ADR specifies the complete addition (layout + validator + API). ADR-100: Reject non-final inline length-prefixed variable fields in aligned mode. The OffsetMap reserves only 4 bytes (the length prefix), but write_string writes prefix+data inline — clobbering subsequent fields. Non-final variable fields must use maxLength or offset-indirect. ADR-101: Packed-mode read API — engine as SequentialReader factory. engine.sequential_reader() returned &SequentialReader but read_next needs &mut self — dead API. Now returns an owned fresh reader. ADR-102: Reject TUnion in aligned mode for v1. The aligned-mode union code had three bugs (no variant offsets, first-variant discriminator offset, misaligned variant region). Unions are the protocol pattern; mmap formats use structs/arrays. Reversible when a consumer needs it.
Alknet
Status: Pre-alpha — This project is undergoing a major architectural pivot to an ALPN-as-service model. The previous implementation has been archived and a greenfield rebuild is in progress.
A self-hostable networking toolkit built on QUIC+TLS with ALPN-based protocol dispatch. Each protocol handler (SSH, SFTP, Git, HTTP, DNS, messaging, call protocol) registers an ALPN string on a shared endpoint. The ALPN negotiation during the TLS/QUIC handshake routes connections to the correct handler before any application bytes are read.
Core Insight
A service IS an ALPN. One endpoint, one port, many protocols — dispatched by the TLS handshake, not by application-level peeking or separate listeners.
