Added

  • [W] U2-bytes (u2.js): three witnesses in four bits, two bits and one u-bit, every
    face built from u.js; test/u2.test.mjs.
  • [W] U5-bytes (u5.js): five u-bits hold 3^5 = 243 values in one eight-bit byte; the
    13 byte values above 242 unpack to u; test/u5.test.mjs.
  • [W] test/number.test.mjs: u is one half (not, and, or are 1 - x, min and max).
  • [R] audio.mjs asks iOS for the playback session before any sound, so the ringer
    switch should no longer mute it; a silent loop keeps older iOS awake. Not run on a
    physical iPhone here; test/audio.test.mjs passes in Node, which has no window.
  • [W] Package exports ./u2 and ./u5.
  • [W] Retained the device repository's contributor instructions in AGENTS.md.

Changed

  • [W] Joined the original core and device histories to nostalgia without
    replacing the newer U source. Namespaced history tags retain all original refs
    and release tags; the perennial experiment keeps its own retained branch.
  • [W] Reassociated the existing device worktree with U, preserving its working
    files, index and reflog. The other linked worktree stays unchanged.
  • [W] checks/verify-sources.mjs says what it establishes and what it does not: the
    manifest is generated from the same files, so it proves bytes unchanged, not correctness.
  • [W] The release manifest lists u2.js, u5.js and their tests, and matches README and audio again.

Removed

  • [W] Removed the retired top-level u-core and u-device checkouts after
    verifying every original Git object in U. The only untracked content removed
    was the generated core burn temporary file; no private state was found.

Fixed

  • [W] Pinned U's prior reflog commits and otherwise unreachable objects with
    Git refs, retaining that local recovery evidence.

Validation

  • [W] Node v26.7.0 on Windows, 6 Oct 2026: node verify.mjs agreed across 3 of 3
    runtimes; node --test over the six test files, 35 of 35 passed;
    sha256sum -c SHA256SUMS.txt matched every listed file.
  • [W] All 245 original Git objects are present (2 Oct consolidation). Windows Git sees
    both retained worktrees; application source is unchanged by the consolidation.

Not checked

  • Physical devices, including the iOS sound change on a real iPhone. Settled by
    playing a page that uses audio.mjs on an iPhone with the ringer switch off.

Its manifest check fails on GitHub (two hashes taken from Windows line endings). Use 1.2.1: same code, corrected manifest.
