 ## Features
 
-- **Historical result replay:** 2023 (Without A Fight), 2024 (Knight's Choice) and 2025 (Half Yours). Published finishing orders are fixed; animated sectional motion is synthetic, never claimed as observed.
+- **Historical preservation:** 11 races, spanning **1861–2025**. The 1988 Empire Rose and 2005 Makybe Diva Cups include documented full-field finishing orders. The six other historic additions are explicitly marked **TOP 3**: they depict only verified podium finishers, not entire fields. The 2023–25 replays remain intact. All intermediate motion is synthetic.
 - **What-if races:** seeded synthetic performance profiles coded in balanced ternary (-1/0/+1), Good/Soft/Heavy scenarios and runner-specific aggressive/balanced/conservative tactics. Results are entertainment, not predictions.
 - **Arcade:** 8-bit pixel horses with jockey silks, top-down circuit, leaderboard, commentary, speed, pause, tick advance, seek, and a follow-horse selector.
 - **Proof-friendly:** integer centimetre state, deterministic PRNG, fixed 420-tick horizon, shared-config links, downloadable JSON evidence and SHA-256 of the canonical complete race timeline. Identical settings + model version => identical results.

+**Scope guarantee:** A TOP 3 exhibit shows three verified finishers from a historically larger field. It is *not* a three-runner historical race. No unsourced names or finishing places are invented; what-if mode is disabled for partial fields. Historical movement remains a deterministic visual reconstruction, not observed sectional or tracking data.
+
+**1988 caveat:** The complete 22-place order comes from a secondary published field table. Empire Rose's victory and Natski's runner-up placing are independently corroborated by VRC; the entire order has not yet been reconciled against a primary race-book or Cavanough's complete historical results. [State Library Victoria](https://guides.slv.vic.gov.au/melbournecup/fields) identifies those archival resources. Older Cups also used period-specific distances and track layouts; the app's 3200-metre diagram is a universal schematic display, not an exact restoration.

 - Track visual is an approximate stylized oval and does not claim to match the Flemington geometry or 3200m path precisely.
 - All race positions are monotonic, integer centimetres, bounded by 0..320000. Timelines are 421 states, ticks 0..420. Date, random clock time and real-time networking are not model inputs.
 - Changes to physics, PRNG, source archive, canonical serialization or rounding require an engine version bump and test fixtures to preserve compatibility.

+## Historical archive scope v0.2.0
+- Every race has evidence links, a documented field-size count, and coverage full or podium (legacy 2023–2025 records implicitly full).
+- Podium mode displays **only verified first-three**, without inventing missing horses or treating three as total starters.
+- What-if mode requires full coverage, enforced in engine as well as UI.
+- All historical animation, lane positions and progress are simulated, never claimed GPS or contemporaneous sectionals.
+- The 1988 full result is sourced to a secondary 22-place table with VRC podium corroboration; a complete independent primary-source reconciliation remains outstanding.
+- Earlier Cups may have used different course geometry and nominal distances. The modern 3200m oval remains schematic.
+- The historical archive update does not change the deterministic physics for original 2023–2025 records.
