Scorecard replacement — staged build

Target: /copper-orchard-47/ (unindexed standalone page)

Design contract

Watch the fight first. During an active round the main interaction is Left/Right.
Arrow presses create observations, never automatic 10-point scores.
Show live red/blue moment totals. End-of-round suggestions preselect an editable score from the counts, but never confirm it automatically.
Recommendation thresholds: no moments -> manual; equal moments -> tentative 10–10; one side ahead -> 10–9; >=6 leading moments, >=5 lead, and >=80% share -> 10–8 review suggestion. These are operator aids, not Unified Rules scoring conclusions.
Round scores are confirmed by the operator under the 10-point-must system.
Keep manual operation available if network connections fail.
No OBS, stream overlays, social graphics, or content-production modules.
Keep historic v1 browser storage keys intact; imports make copies.
Never infer official results from the operator’s unofficial scorecard.

Multi-event dashboard with a fight card and editable corner labels, division, and bout order.
Three-/five-round fights and 3-/5-/10-minute clock settings.
Focused judging view with Left/Right observations, keyboard shortcuts, undo, timing controls, and an observations timeline.
End-of-round score confirmation (10–9, 10–8, 10–7, explicit 10–10) with referee deductions.
Running totals, fight closure for decisions and stoppages, results stored separately from scores.
Local autosave, JSON full-workspace backup/import, CSV scorecard export, manual v1 session migration.
Guardrails: no-repeat input, no scoring from keypress counts, accidental early end confirmation, score-edit and deletion confirmation.

Stage 1 exit criteria:

QA: multi-round decision and points; stoppage; reload; legacy migration; local backup.
Keyboard controls never interrupt viewing, with no mouse required during active rounds.
State persists across refresh, without changing historic saved keys.

Optional Google Drive synchronization (Google user consent); preserve local-first operation.
Import scheduled cards through an authorized source, maintain offline manual entry.
Optional official result/scorecard comparison; clearly distinguish provenance.
Search and filters for historic events and rounds.
Safer multi-device conflict resolution and duplicate-fight checks.

All data currently lives in that browser’s local storage; clearing site data removes it unless exported.
Keep JSON backups, particularly before device changes.
Link obscurity + noindex are not access control; add authentication if data privacy becomes necessary.
The old v1 page can be recovered from the Git history. New app does not delete the older v1 local storage keys.
