Rank

Interactive feature prioritization tool for rank.friborg.uk.

Product definition

Rank is a fast intake and prioritization board for product ideas from Jimmi and agents.

Core loop:

Capture idea → score impact/effort/confidence/urgency → drag into milestone → revisit top-ranked work

Chosen subdomain: rank.friborg.uk — short, memorable, and honest about the job.

UX principles

• One-screen capture, no modal ceremony.
• Keyboard-first: / focuses capture, Enter saves.
• Plain sharp visual system: zero rounded corners, dark space/glass, high contrast.
• Milestones are customizable lanes, not a rigid roadmap prison.
• Agents can post ideas through the same API endpoint as the UI.

Architecture

• Node/Express app on port 3045
• Static SPA in public/
• Appwrite TablesDB persistence
• Docker deploy on Unraid
• Gitea remote repo
• Nginx Proxy Manager routes rank.friborg.uk → 192.168.30.100:3045

Appwrite schema

Database: priority_rank

Tables:

• ideas — title, description, source, sourceName, milestoneId, impact, effort, confidence, urgency, score, rank, labels, notes, archived
• milestones — name, description, horizon, color, position, active
• activity — small append-only UX feed

Scattermind → Ranker bridge

Ranker's continuation job is narrow:

Snapshot / Concept Map → candidate feature/action set → Rank-ready build order

POST /api/rank-feedback accepts a prioritix-feature-set-v1-style payload from Scattermind and returns ranked items plus buildOrder.doFirst / validateNext / defer / park. It accepts candidate arrays as features, actions, nextMoves, or candidates either at the top level or under featureSet, and it can consume a nested conceptMap.nextActions / nextMoves artifact directly, so Scattermind can hand off Concept Map next actions without renaming them into fake software features. It also returns a handoff object (rank-feedback-result-v1) with source provenance, item trace rows, and contract warnings for missing artifact IDs, source sections, original prompt provenance, or evidence on active items. Keep this contract action-first; do not use it as a reason to add generic dashboard, auth, billing, or workspace layers before the bridge has proof.

Candidate items may include optional 1–10 rankerHints (value, effort, confidence, urgency, revenue, novelty, risk). Ranker blends those explicit Scattermind hints with text heuristics; effort is inverted into feasibility. Hints improve the defended order, but recommendedLane: "defer" or "park" remains a safety rail so dashboard-swamp items do not get promoted by flashy wording. For clean bridge handoff, Scattermind should send sourceSection and evidenceNeeded on each active next move. Scattermind can also send targetAudience, constraints, assumptions, and nonGoals / avoid at the top level, in featureSet, or inside conceptMap.context; Ranker returns that decision context in input.decisionContext and handoff.decisionContext, and penalizes candidates that conflict with source non-goals (for example saved workspaces/auth/billing before the continuation proof).
