The builder operates on four files in the consumer repository:
.typos-oxendict-base.tomlis the untracked local cache of the shared dictionary..typos-oxendict-base.jsonis untracked refresh metadata.typos.local.tomlis the tracked repository-specific overlay.typos.tomlis the tracked, deterministic generated output.
The shared dictionary remains authoritative for estate-wide Oxford spellings. The local overlay is only for repository-specific accepted terms, corrections, patterns, and file exclusions. It must not weaken or contradict the shared policy.
