**Problem:** `docs/camelot_deep_dive.md §3.1` currently assigns the A/B letter purely via `flair = (Technique + Pace) / 2` vs `structure = (Decisions + Intelligence) / 2`. This binary split ignores…

**Problem:** Clubs can find individual players whose Camelot key is harmonic with the club profile, but there is no surface that shows the *squad as a whole* — whether the 25-man roster is harmonically balanced, over-weighted in one key cluster, or missing an entire tonal zone (e.g. no expressive B-key presence in the midfield arc). **The idea:** A 'Squad Harmonic Audit' screen, accessible from the Club Profiling / Shadow Team area, that renders the Camelot Wheel with each squad slot mapped onto it. Each occupied key lights up proportionally (bubble size = number of players in that key). Empty or under-populated keys are flagged in amber/red. The screen outputs three actionable signals: 1. **Dominant key** — the key your squad clusters around (e.g. '11A — structural CB-heavy'). 2. **Gap keys** — keys with zero players, colour-coded by how harmonically critical they are to the club's stated philosophy. 3. **Tension pairs** — two current players whose keys are ±6 apart (maximum dissonance), surfaced as a coach-level warning. A one-click 'Fill the gap' CTA filters the player pool to candidates whose Camelot key addresses the identified gap — directly closing the loop from audit → shortlist. **Why now:** The Camelot key math is already computed per player (per `docs/camelot_deep_dive.md` §3.1) and the 25-man squad structure exists in Shadow Team. This idea requires no new data — only a new aggregation view over existing keys. The club profile already stores philosophy, which drives the 'critical gap' weighting. **Measurable ship-and-check metric:** % of sessions where a user clicks 'Fill the gap' CTA after viewing the audit — target >15 % within first 10 club accounts.
