aprender 0.65.2 — the parity-instrument release, fully published

0.65.0 was cut at 587ad0797 and its crates.io cascade stopped at 48 of 74 crates: five sibling dev-dependencies carried a version through the workspace alias, so aprender-core (needs aprender-data) could not be uploaded before aprender-test-lib (needs aprender-core). 0.65.1 (cut at 752f55346) fixed that and reached 64 of 74 crates before aprender-test-lib failed its publish verification (an include_str! of a file outside the crate). 0.65.2 supersedes both for every crate (74/74 on crates.io, drained 2026-09-04 23:20Z); v0.65.0 and v0.65.1 stay where they were cut.

Fixed since 0.65.0

  • Packaging (PMAT-958, #2866). aprender-test-lib embeds scripts/perf-matrix.yaml through build.rs and a vendored copy that may never drift; the CB-510 guard now reports any include_str!/include_bytes! in host-compiled code whose target escapes the crate.
  • Publish cycle (PMAT-955, #2864). The five dev-dependencies are path-only; check_publish_preflight.sh rule R6 refuses any sibling dev-dependency that carries a version (fixture on both polarities, mutation RED).
  • Drain log (PMAT-954, #2864). cascade-drain.sh keeps the DEFER lines that say why a crate did not publish.
  • wgpu init deadlock (PMAT-952, #2862). The shared_instance initializer no longer takes DEVICE_INIT_LOCK, which GpuDevice::new already holds while calling it (ABBA on a process's first initialization; the 0.65.0 release clean-room parked 49 threads on it).
  • stdio MCP transport (PMAT-953, #2863; PMAT-950, #2860). A server that answers and exits before reading the request keeps its response and its exit status instead of surfacing write stdin: Broken pipe.

What 0.65.x is

PP-LLAMA-001 v3.1: the parity spec and the instrument it describes — perf_gate.sh with merge and release phases, paired/interleaved receipts with bootstrap statistics, the PP-26 batch-invariance witness, the PP-9 spend ledger with its scanner (PMAT-930..935), the F-9 publish preflight, and UNMEASURED cells with owners and expiries instead of numbers. No parity ratio is published in this release; every c>1 band is INVALID-CORRECTNESS until the witness passes on the release hosts (see docs/specifications/0.66-performance-parity-report.md for the 0.66 plan).

Known

  • CHANGELOG.md has no 0.65.1 or 0.65.2 entry: the claim-literal baseline is line-keyed and refuses the coordinate shift a changelog insert causes (PMAT-956); the entry lands with that guard fix.
