Milestone 4.5.C.4 — Dashboard Integration

Status: Planned
Goal: Track C — Directive Regression Testing
Phase: 4.5 — Intelligence Layer
Estimated effort: 2 days
Track: Track C — Directive Regression Testing

Why This Milestone Exists

Completes the directive management UX from the spec — version timeline, diff viewer, regression scenarios with pass/fail/critical-fail states, and a live rollout progress view that didn't exist in the original UX spec because gradual rollout was never designed with a mechanism until Milestone 4.5.C.3.

Orientation (indicative)

Named paths, package layouts, libraries, schemas, env vars, and commands anywhere on this page are rough sketches for orientation — inspiration and a baseline, not a required change list.

During implementation, expect to:

open the live tree and follow existing patterns before inventing new ones
research current constraints (latency, tenancy, deploy shape, libraries) more deeply than this page can
advance the design beyond the sketch where measurement or code reality says so
land work in different filenames, merged packages, deferred docs, or new surfaces when the situation calls for it

Prefer outcomes over matching any particular file tree or command sequence.

Areas that may be involved (situational — not a checklist):

Directive regression / promotion
Operator dashboard

Success signals

Outcome-oriented signals that the milestone is in good shape. Exact filenames, package layouts, and commands may differ from any sketches above.

Regression scenario list renders pass/fail/critical-fail states with judge disagreement indicator
Rollout progress view polls rollout_percentage and drift metrics live, with pause action
Playwright E2E: full submit-review → regression pass → promote → gradual rollout → auto-advance flow
