footy-data-kit v1.0.0

Summary

Marks the Wikipedia overview pipeline as the v1 source-of-truth path for the supported English league-table dataset: 138 season records from 1888 through 2025 and 232 generated club metadata records.
Turns the release process into a fail-closed workflow with dry-run completeness checks, schema validation, data verification, club-continuity verification, release-note validation, docs generation, and integration coverage reporting.
Clarifies the v1 data contract for consumers: tier keys represent pyramid levels, row-level administrative outcomes are explicit, club metadata fields are documented by stability/caution area, and known historical ambiguity is called out instead of guessed.

None.

Preserved the canonical tierN pyramid-level contract, including Third Division North/South under tier3.divisions[] before 1958 and modern National League North/South under the level-six parallel structure.
Added explicit row-level administrative outcomes with outcomeStatus for reviewed cases including resignation, folded clubs, expulsion, reprieve, points-deduction relegation, and expelled-and-folded rows.
Corrected 1957-58 restructure semantics so Fourth Division placement rows are no longer treated as ordinary relegation outcomes.
Kept generated club metadata at 232 records and documented the v1 meaning of generated observations, curated/source-backed history, derived relationships, and caution areas in docs/v1-metadata-audit.md.
Expanded integration fixtures to 49 of 138 seasons, or 35.5%, with coverage across early Football League seasons, test-match era movement, the first Third Division, Third Division North/South, the 1958 restructure, Premier League and EFL naming eras, COVID/pandemic seasons, administrative club outcomes, tier 5, and modern level 6.

Fixed release verification so directory scans no longer treat non-FootballData JSON sidecars as valid "0 seasons" datasets.
Fixed release dry-run behavior so incomplete regenerated output fails before minification and schema checks can produce a false green.
Fixed administrative/restructure verification gaps around 1957-58 placement rows and 2019-20 Bury, Stevenage, and Macclesfield Town semantics.
Fixed reprieve and canonical tier-label handling inherited from the v0.9.1 prep work.

Release dry-run data generation completed with 138 seasons and 232 club metadata records, then passed data verification, club-continuity verification, and JSON Schema validation.
Integration coverage reports 49 covered seasons, 57 live integration tests, 153 table-row assertions, 218 transition-team assertions, 16 tier-metadata assertions, and 15 season-info assertions.
pnpm -s test:jest, pnpm -s test:integration, pnpm -s verify:data, pnpm -s lint, pnpm -s typecheck, pnpm -s format:check, pnpm -s docs:check, and release-note validation have passed during v1 prep.
Release notes and docs pages are generated from checked-in release metadata, and release-note validation now guards required sections for the active package tag.

The v1 supported scope is the generated English league-table dataset from the maintained wikipedia/ overview pipeline. Legacy rsssf/ code remains outside the active ingestion path.
No schema break is included in v1. Consumers should still treat outcomeStatus and documented metadata fields as the clearer source for administrative outcomes and lifecycle/status interpretation.
trackedFromSeason and trackedToSeason in club metadata are observed coverage bounds in the generated dataset, not founded/dissolved dates.
status.current is a current high-level club metadata status, not a per-season table-row outcome. Use row-level fields such as outcomeStatus, wasRelegated, wasReprieved, and notes for season-specific interpretation.
derived.relationships is an audit/navigation aid for lineage-like records, not legal proof of club continuity.

V1 is source-of-truth ready for the supported generated scope; it is not a claim of exhaustive lower-tier history or complete legal-entity modeling for every club.
Tier 5 and tier 6 are covered by targeted modern fixtures and generated data where source pages expose usable tables, but they are not yet as deeply vetted as tiers 1-4.
Club metadata includes source-backed lifecycle and lineage work for reviewed records, but unresolved historical ambiguity is documented or deferred rather than filled with weak assertions.
TypeScript migration remains partial. The main contracts, output normalization, verification, and release gates are stronger, but parser-heavy modules are still mostly JavaScript.

No season-table changes were detected after regenerating the release data.

Release data is regenerated from the Wikipedia overview pipeline and checked before publishing.
