• [x] Repo -- ldraney/botfire
• [x] Question -- 7 sub-questions covering price bands, timing, risk params, time windows, volume, seasonal availability, sample size
• [x] Deliverables -- 3 deliverables: analysis doc, follow-up tickets, or no-action rationale
• [x] Time-box -- 3 hours
• [x] Related -- 4 related items (project-botfire, #11, #12, #14)

Traceability

• [x] story:bot-strategy label -- present on board item

Repo Placement

Dependencies

• Spike #11 (Live Edge deep dive, item #1845) -- COMPLETED (in qa column). This spike follows it. No blocker.
• Issue #12 (Evening filter, item #1846) -- PR #16 merged, in qa. Related (sport-specific hours may differ) but not a blocker.
• Issue #14 (Ceiling 89c, item #1848) -- PR #15 merged, in qa. Related (sport-specific bands may differ) but not a blocker.
• No items block this spike. No undocumented dependencies found.

Acceptance Criteria

• docs/multi-sport-analysis.md exists with per-sport sections -- verifiable via file check
• Follow-up tickets created on Forgejo for viable sports -- verifiable via API
• If no viable sports, docs file contains rationale -- verifiable via content check

Blast Radius

• game_phase.rb -- already handles baseball, basketball, football, hockey, soccer with sport-specific "nearly over" and "about to settle" logic
• scanner.rb -- DEFAULT_SPORTS already includes all 5 sport types
• bot.rb -- SPORT_TYPES constant already lists all 5 sports; watched_sports defaults to all
• bot_engine.rb -- already filters by watched_sports, active hours are per-bot configurable
• portfolio_grouper.rb -- already groups positions by sport_type
• live-edge.md -- already documents game phase filters for all 5 sports
