Architecture decision records

One file per decision that a future contributor is likely to question. An ADR records the context at the time, the options that were on the table, the choice, and what it costs. ADRs are never edited after acceptance except to mark them superseded; a change of mind is a new ADR that supersedes the old one.

ADR	Title	Status
0001	Monotonic 0.0.x versioning and suite lockstep	Accepted
0002	Dual licence, Apache-2.0 OR MIT, declared with PEP 639	Accepted
0003	Example corpus: two corpora, one engine, twelve scoped decisions	Accepted

Template: copy template.md, number it next, add a row here, and open it in the pull request that implements the decision.
