The Rust ecosystem convention, and what kickscore, xy and saphyr already use —
kickscore being the closest sibling to this crate.
LICENSE-APACHE is the canonical 201-line Apache-2.0 text with the appendix
left as the unfilled template, which is the form Rust crates ship. LICENSE-MIT
carries the copyright line. Both are picked up by cargo automatically and
appear in the packaged crate.
This also unblocks the release workflow. `cargo publish` does not check the
license field when the target is an alternative registry, but cargo-release
does, and refuses outright:
error: trueskill-tt is missing the following fields:
license || license-file
--no-verify does not bypass it. So `just release` was inert without this,
whatever cargo publish alone would have accepted.
README gains the conventional dual-license section and the contribution note
that dedicates inbound contributions under the same terms.

The CLAUDE.md architecture section still described the pre-redesign engine:
its data flow named `Batch`, `Agent`, `Player` and `message.rs`, none of
which have existed since T2, and the public API it listed did not match
`lib.rs`. It is the first thing a fresh session reads, so it was actively
misleading. Rewritten against the current module layout, with the invariants
that are easy to violate — ties needing a positive `p_draw`, NaN never being
convergence, log-space evidence, color contiguity, `forbid(unsafe_code)`,
and ingestion-order equivalence — written down.
The README Todo list had five entries that were already done, including
"Time needs to be an enum": `Time` has been a trait since T2, and the
`batch::compute_elapsed()` it pointed at no longer exists. The genuinely
open item — cross-checking `quality()` against sublee/trueskill — stays.
`benches/ingest.rs` measures one-event-per-call against a single batched
call. The rest of the suite only measured batched construction, which is why
the quadratic fixed earlier on this branch went unnoticed for so long.
`TimeSlice::log_evidence` also hashes its target set once instead of
scanning the slice per player per event, so `log_evidence_for` with many
keys is no longer quadratic.
