+# profile-stats Specification
+
+## Purpose
+TBD - created by archiving change profile-stats. Update Purpose after archive.
+## Requirements
+### Requirement: Lifetime totals on the profile
+The profile page SHALL show a stats header with the owner's lifetime totals: activity count, total distance, total ascent, and total elapsed time.
+
+#### Scenario: Totals shown for an athlete with activities
+- **WHEN** a user views a profile whose owner has activities
+- **THEN** a stats header shows the activity count, total distance, total ascent, and total elapsed time
+
+#### Scenario: Header hidden when there are none
+- **WHEN** the profile owner has no activities the viewer may see
+- **THEN** no stats header is shown
+
+### Requirement: Viewer-scoped roll-ups
+The roll-up SHALL count only the activities the viewer is permitted to see: public-only for other viewers, and all of the owner's activities when the owner views their own profile.
+
+#### Scenario: Visitor sees public-only totals
+- **WHEN** a visitor (not the owner) views a profile
+- **THEN** the totals aggregate only the owner's public activities (unlisted and private are excluded)
+
+#### Scenario: Owner sees their full totals
+- **WHEN** the owner views their own profile
+- **THEN** the totals aggregate all of the owner's activities regardless of visibility
+
+### Requirement: Recent-activity summary
+The stats header SHALL show the count of activities in the last 4 weeks (rolling), under the same viewer scoping as the totals.
+
+#### Scenario: Last-4-weeks count
+- **WHEN** the stats header is shown
+- **THEN** it includes the number of the owner's (viewer-scoped) activities started in the last 28 days
+
+### Requirement: Localized stat labels
+The stats header SHALL render its labels and units through localized strings.
+
+#### Scenario: German labels
+- **WHEN** the UI locale is German
+- **THEN** the stat labels render in German
+

+# profile-weekly-distance Specification
+
+## Purpose
+TBD - created by archiving change profile-weekly-distance. Update Purpose after archive.
+## Requirements
+### Requirement: Weekly distance chart on the profile
+The profile page SHALL show a weekly-distance bar chart beneath the stats header, with one bar per week for the last 12 weeks and bar heights normalized to the busiest week in the window.
+
+#### Scenario: Chart shown when there is recent distance
+- **WHEN** a user views a profile whose owner has distance in the last 12 weeks
+- **THEN** a 12-week bar chart is shown, the tallest bar being the week with the most distance
+
+#### Scenario: Chart hidden without recent distance
+- **WHEN** the owner has no (viewer-visible) distance in the last 12 weeks
+- **THEN** no weekly chart is shown
+
+### Requirement: Contiguous weekly axis
+The chart SHALL render a contiguous run of weeks, including weeks with no activity as zero-height bars, so the axis is stable.
+
+#### Scenario: Empty weeks appear as gaps
+- **WHEN** the owner was active in some weeks of the window but not others
+- **THEN** the inactive weeks render as zero-height bars in their correct position (not omitted)
+
+### Requirement: Viewer-scoped weekly distance
+The weekly distance SHALL be scoped to what the viewer may see: public-only for other viewers, and all of the owner's activities when the owner views their own profile.
+
+#### Scenario: Visitor sees public-only weeks
+- **WHEN** a visitor (not the owner) views a profile
+- **THEN** each week's bar reflects only the owner's public activities
+
+### Requirement: Localized chart labels
+The chart SHALL render its label and per-bar distance readouts through localized strings.
+
+#### Scenario: German labels
+- **WHEN** the UI locale is German
+- **THEN** the chart label and distance readouts render in German
+
