Kell Creations Operations Platform — Master Development Brief

Recommended repo location

Place this document in the repository at:

docs/development/master_development_brief.md

Why this location:

• keeps it versioned with the code
• makes it easy for Cline to read and update
• separates implementation planning from feature code
• works for both web and Android roadmap tracking

If docs/development/ does not exist yet, create it.

---

Purpose

This document is the master implementation brief for continuing development of the Kell Creations Flutter operations platform across web and Android. It is intended for use by Cline in Windows 11 VS Code.

This brief should be treated as the working source of truth for planned development after the current completed slices already landed on main.

---

Working model

Development must proceed in small, reviewable vertical slices.

Rules:

• Branch from current main for each stage or sub-slice.
• Implement on a feature branch.
• Validate locally.
• Open a PR into main.
• Merge only after tests/analyze are clean.
• Do not stack broad unfinished work directly on main.
• After each merged slice, update this brief so it remains aligned to main.

---

Current confirmed baseline on main

Platform structure

• apps/kell_web exists.
• Shared packages include:
  • core
  • design_system
  • feature_inventory
  • feature_wordpress
  • feature_orders
  • feature_policy
• App shell, routing, dashboard, reusable shell widgets, AppServices, and AppScope are implemented.
• Dashboard uses app-composed repository data.
• Vertical slices exist for Inventory, Products/Publishing, Orders, and Policy/Governance.
• Cross-feature navigation handoffs and shared filtering/search/selection persistence are implemented.
• Runtime bootstrap uses:
  • KC_ENV
  • KC_WC_SITE_URL
  • KC_WC_CONSUMER_KEY
  • KC_WC_CONSUMER_SECRET
• App supports FAKE and WP modes with visible shell badge.

Product publishing workflow already landed on main

• Controlled WooCommerce publish action landed.
• ProductDraft.copyWith landed.
• unpublished -> draft UI exposure landed.
• pendingReview -> draft UI exposure landed.
• unpublished semantics clarified as a read-only abstraction.
• Status action success/failure feedback landed.
• Publishing page polish landed.
• Richer read-side detail preview landed.
• Price-only product edit landed.
• Search/filter/sort refinement landed.
• Name-only product edit landed.

Current narrow edit capabilities on main

• update product status through controlled workflow
• update product price only
• update product name only

Latest known validation state on main

• flutter analyze clean
• feature_wordpress tests passing
• kell_web dashboard tests passing
• latest reported count for feature_wordpress: 195/195 passed
• latest reported count for kell_web dashboard tests: 10/10 passed

---

Non-negotiable architectural constraints

These must be preserved in all future work:

• Preserve strict package boundaries.
• Fake repositories remain in feature packages.
• Real integrations are incremental alongside fake ones.
• Runtime selection stays via --dart-define, not a settings UI.
• No credentials hardcoded or committed.
• Do not broaden into generic product editing prematurely.
• Keep WooCommerce details inside the WP repository layer.
• Keep diffs small and reviewable.
• Prefer inspection-first development.
• Android support should reuse shared feature/domain/application layers rather than fork logic.

---

Development stages

Stage 1 — Web application completion: controlled product editing

Objective

Extend the publishing workflow with additional single-field edit capabilities using the same narrow pattern already established by price-only and name-only update.

Branching model

Use one branch per edit slice:

• feat/description-only-edit
• feat/category-only-edit

Stage 1A — Description-only product edit

Goal

Allow updating product description only.

Requirements

• Inspect the existing price-only and name-only edit implementations first.
• Mirror the narrow pattern for description update.
• Add one repository method or equivalent narrow path only if needed.
• Fake and WP repositories evolve in parallel.
• Use existing controller result/feedback patterns.
• Keep WooCommerce payload logic in WP repo only.
• Do not expose any other editable fields.
• Keep description editing plain and controlled.
• Do not add a rich text editor.

Expected artifacts

• repository contract update
• fake repo implementation
• WP repo implementation
• use case
• controller action/result handling
• preview panel inline description edit UI
• targeted repo/controller/widget tests

Definition of done

• product description updates end-to-end in FAKE and WP modes
• no generic update API introduced
• tests/analyze clean

Stage 1B — Category-only product edit

Goal

Allow updating product category only.

Requirements

• Use existing category representation only.
• Do not create full taxonomy management.
• Keep write mapping narrow inside WP repository.
• Use a simple constrained UI.
• Reuse the established narrow single-field edit pattern.

Definition of done

• category can be updated through a controlled workflow
• no taxonomy subsystem added
• tests/analyze clean

---

Stage 2 — Web application operational hardening

Objective

Improve operator consistency, predictability, and usability after writes.

Branches

• feat/post-write-consistency
• feat/publishing-ux-hardening

Stage 2A — Post-write consistency hardening

Goal

Make list/detail behavior predictable after edits and status changes.

Requirements

• preserve selection after update where sensible
• maintain search/filter/sort persistence after writes
• handle item repositioning under active sort cleanly
• ensure latest values refresh correctly
• verify last-modified updates behave consistently

Definition of done

• post-action behavior feels stable and predictable
• focused tests cover persistence and repositioning

Stage 2B — Publishing workflow UX hardening

Goal

Tighten the publishing workflow without broadening scope.

Requirements

• refine success/failure wording if needed
• improve inline validation messaging for single-field edits
• ensure disabled/loading states are consistent
• ensure page-level load errors remain separate from row-level action errors

Definition of done

• status/edit actions feel reliable and operator-friendly
• no architecture broadening

---

Stage 3 — Web application operator efficiency

Objective

Increase throughput for product triage and management using existing data.

Branches

• feat/multi-select-groundwork
• feat/list-efficiency-improvements

Stage 3A — Multi-select groundwork (read/state only first)

Goal

Prepare for future bulk actions without implementing bulk writes yet.

Requirements

• add selection model for multiple items
• show selected-count UI
• allow clear selection
• preserve current single-item preview behavior where appropriate
• do not add bulk publish/edit/delete actions yet

Definition of done

• multi-select state exists and is tested
• no bulk writes introduced

Stage 3B — List efficiency improvements

Goal

Further improve operator productivity.

Candidate scope

• denser list/card presentation if justified
• quick visual indicators for stale products
• lightweight secondary metadata visibility
• improved keyboard/focus handling on web if easy to support

Definition of done

• measurable usability improvement using existing data only

---

Stage 4 — Android application foundation

Objective

Bring the current operations platform capabilities to Android using shared packages first and platform-specific UI only where required.

Key principle

Business logic, domain logic, repositories, and feature application logic should remain shared. Android should primarily add a dedicated app shell and mobile-optimized presentation.

Branches

• feat/android-app-shell
• feat/android-publishing-surface

Stage 4A — Android app shell and bootstrap

Goal

Create the Android app entry and shell for the existing platform.

Requirements

• add or adapt app target for Android
• reuse shared packages and feature modules
• preserve runtime environment selection model
• ensure FAKE mode works cleanly on Android first
• mobile shell/navigation should stay simple and consistent with shared app structure

Definition of done

• app runs on Android emulator/device in FAKE mode
• shell, navigation, and core screens render
• analyze/tests remain clean

Stage 4B — Android publishing surface

Goal

Adapt the publishing workflow for mobile form factor.

Requirements

• reuse shared controller/use case/repository layers
• optimize preview/edit interactions for smaller screens
• keep feature parity for current publishing workflow where feasible
• do not fork business rules for Android

Definition of done

• Android supports browsing, filtering, status changes, and existing narrow edits
• mobile presentation is usable and tested where practical

---

Stage 5 — Android operational maturity

Objective

Harden Android UX after the core feature surface works.

Branches

• feat/android-feedback-polish
• feat/android-mobile-ux-hardening

Stage 5A — Android feedback and action polish

Goal

Ensure action feedback patterns translate cleanly to Android.

Requirements

• reuse shared action result model where possible
• adapt SnackBar/feedback timing and presentation appropriately
• validate status/edit workflows on mobile

Stage 5B — Android mobile workflow hardening

Goal

Improve ergonomics on smaller screens.

Requirements

• verify scrolling/selection/edit flows
• ensure touch targets and inline edit behavior are mobile-friendly
• refine layout without changing shared domain/application contracts

---

Stage 6 — Controlled bulk actions (only after groundwork)

Objective

Add carefully scoped bulk operations once single-item workflows are stable across web and Android.

Branches

• feat/bulk-status-actions
• feat/bulk-operator-workflows

Entry criteria

Do not begin until:

• single-item edit/status flows are stable
• multi-select groundwork is complete
• post-write consistency is hardened
• Android core publishing surface exists

Candidate first bulk action

• bulk move to draft

Explicitly defer

• bulk generic edit
• bulk category management
• destructive bulk deletion unless separately justified

Required development workflow for every slice

For every branch/stage:

1. Start from latest main.
2. Inspect first.
3. Write a brief inspection report.
4. Propose the smallest implementation plan.
5. Implement only the current slice.
6. Run targeted tests.
7. Run flutter analyze or dart analyze as appropriate.
8. Summarize changed files and validation results.
9. Open PR into main.
10. Merge only after clean review and validation.

---

Standard Cline operating prompt

Use this at the start of any new slice:

Continue the Kell Creations Flutter operations platform workstream from current main.

Read docs/development/master_development_brief.md first and follow it as the authoritative planning document.

Constraints:
- Preserve strict package boundaries.
- Fake repositories remain in feature packages.
- Real integrations are incremental alongside fake ones.
- Runtime selection stays via --dart-define, not settings UI.
- No credentials hardcoded or committed.
- Do not broaden into generic product editing prematurely.
- Keep WooCommerce details inside the WP repository layer.
- Use small, reviewable steps only.
- Work is being driven through Cline in Windows 11 VS Code.

Working rules:
1. Inspect first. Do not edit immediately.
2. Summarize current relevant state from main.
3. Propose the smallest implementation plan for the requested slice.
4. Implement only that slice.
5. Add/update focused tests.
6. Run validation.
7. Report changed files and validation results.
