Enables queries: what changed this week, why this requirement changed, newly introduced risks, recent architectural evolution.

GitHub-issue-style compact card for search results and lists: name, stability chip, meter %, last edited, ref / impl / test counts, urgency flag ( e. g. recently changing ). Composes [stability_meter], [churn_heat_bar], [dependency_pulse] as optional rows — not all at once by default ( token / UI density ).

Segmented meter + percent ( e. g. Stable █ █ █ █ █ █ █ █ █ ░ 91 % ) derived from edit frequency, age, dependency churn, and issue count — not raw git status. AI and humans use it as a confidence cue for change. Pair with [confidence_card] and [risk_signals].

Compact sparkline of edit intensity over time for a requirement, file, folder, or subsystem ( e. g. ▁ ▁ ▂ ▁ ▁ ▇ █ ▆ ▂ ▁ ▁ ). Hover reveals synthesized story ( stable / large rewrite / quiet since ). Consumes [development_history_signals] and [project_activity_signals].

Spatial dependency summary instead of " Parents: 4 / Children: 12 ". Compact compass ( ↑ parents, → children, ← siblings, ↓ dependents ) and / or a filled * * Dependency Load * * bar showing centrality growth. Consumes [requirement_signals] and [relationship_signals]. Surfaced on focus hero and graph node details. Click any arm or the centre toggles a reference table below the compass ( Dir / Role / Idea / Status ) per ["../activitybar-panels/current_context_scope.rq".dependency_pulse_table].

Pre-edit checklist card: High / Medium / Low confidence with check / warn rows ( stable, reviewed, tested, high fanout, … ) and a confidence %. Shown before AI modify workflows ( [features_ai.ai_integration] ) and on focus when synthesis is available.

Prefer actionable history over staged / unstaged alone. development_context ( git reimagined ): current branch, active issue, release version, commits, authors, change frequency / velocity, historical and semantic hotspots, last meaningful modification, first introduction, ownership concentration, refactor / merge likelihood, stability score. First UI consumer beyond create / modify dates: [context_scope_v1.git_context] / ["activitybar-panels/current_context_scope.rq".git_history_lens] — focus commit trail and authors; working-tree staging demoted to secondary.

currently changing subsystem, hot / cold modules, high activity area, merge conflicts nearby, active branch, recent issue cluster, recent requirement churn, release / milestone affected.

related_requirements, parents, children, incoming / outgoing references, linked implementation files, coverage status, requirement age, stability, priority, verification state, orphaned, cycles, missing references.
