+catalog RPM, magazine, reload, rated body-hit throughput, and magazine-cycle
+body-hit throughput. Include a visible formula and exclusions block with these
+exact formulas:
+
+- `selected damage × (RPM ÷ 60)` for rated body-hit throughput;
+- `(magazine × selected damage) ÷ ((magazine ÷ (RPM ÷ 60)) + reload seconds)`
+  for magazine-cycle body-hit throughput.
+
+The panel is evidence-only. It excludes inferred or substituted values, combat
+profiles, effects, Talents, Attribute totals, calculation profiles, accuracy,
+critical hits, headshots, enemy mitigation, target count, encounter uptime,
+rotations, and simulation. It must not present these values as actual, expected,
+or encounter DPS. When a required source value is unavailable or invalid, show
+`NOT AVAILABLE` and list the missing source fields under the metric; never
+display zero as a placeholder.

+# Weapon baseline prototype
+
+## Scope
+
+`calculateWeaponBaseline` is a pure, client-safe Builder helper. It records
+weapon ID, name, and label, then reports three evidence-only metrics:
+
+- `selectedDamage`: the supplied positive finite damage value.
+- `ratedBodyHitThroughput`: `selectedDamage × rpm / 60`.
+- `magazineCycleBodyHitThroughput`:
+  `(selectedDamage × magazine) / (magazine / (rpm / 60) + reloadSeconds)`.
+
+Unknown, absent, non-positive, non-finite, or invalid source values make only
+the metrics that depend on them unavailable. The helper preserves decimal inputs
+and does not substitute values.
+
+These are not actual, expected, or encounter DPS. They contain no hit
+probability, critical or headshot outcomes, target state, or encounter timeline.
+The rated metric is nominal continuous body-hit throughput; the magazine-cycle
+metric includes the supplied reload interval.
+
+## Excluded inputs
+
+This helper does not read combat profiles, effects, talents, Attribute totals,
+calculation profiles, encounter assumptions, or any other build inputs. It does
+not call the simulation or combat engines.
+
+`selectedDamage` is already the equipped weapon damage used at this boundary. It
+is consumed exactly once; no additional level scaling or damage scaling is
+applied.
+
+## Missing data for a DPS model
+
+A valid DPS model still needs the authoritative damage calculation and its
+modifiers, hit and critical/headshot assumptions, firing and reload behavior,
+target and encounter assumptions, and the timing and contribution of talents,
+effects, Attributes, skills, and weapon swaps. Those data are outside this
+baseline.
+
+This is Builder-only, local prototype work. It does not define the player DPS
+simulation contract or change the existing calculation architecture.
