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

Current narrow edit capabilities on main

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

Latest known validation state on main

  • dart analyze clean
  • feature_wordpress tests passing
  • kell_web dashboard tests passing
  • latest reported count for feature_wordpress: 294/294 passed
  • latest reported count for kell_web dashboard tests: 5/5 passed
  • baseline commit: merge of feat/list-efficiency-improvements (2026-05-22)

Next recommended branch

feat/android-app-shell — Stage 4A: Android app shell and bootstrap. Branch from latest main. Stage 3 (web application operator efficiency) is complete.

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 ✅ COMPLETE

Merged feat/description-only-edit → main at cebac4c (2026-04-11). All artifacts delivered: repository contract, fake/WP repo implementations, use case, controller action/result handling, preview panel inline description edit UI, and targeted tests (212 total feature_wordpress tests passing).

Stage 1B — Category-only product edit ✅ COMPLETE

Merged feat/category-only-edit → main at 8e7e4cb (2026-04-11). All artifacts delivered: repository contract, fake/WP repo implementations, use case, controller action/result handling, preview panel inline category edit UI, snack bar feedback, and targeted tests (223 total feature_wordpress tests passing). Stage 1 complete.

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 ✅ COMPLETE

Merged feat/post-write-consistency → main at 7acff83 (2026-04-11). Added _refreshSelection() to ProductPublishingController to preserve/refresh selection after all write-triggered reloads. 11 new post-write consistency tests added (234 total feature_wordpress tests passing).

Stage 2B — Publishing workflow UX hardening ✅ COMPLETE

Merged feat/publishing-ux-hardening → main at b81016d (2026-04-11). Added inline validation error messages for all four single-field edits (name, price, description, category), disabled text fields and save buttons during isUpdating, and appended error detail to failure snack bars. 13 new tests added (247 total feature_wordpress tests passing). Stage 2 complete.

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) ✅ COMPLETE

Merged feat/multi-select-groundwork → main (2026-05-22). Added multi-selection state to ProductPublishingController (toggleMultiSelect, clearMultiSelection, selectAllVisible, isMultiSelected, multiSelectedIds, multiSelectedCount). Updated ProductDraftCard with optional leading checkbox for multi-select mode. Added _MultiSelectBar to ProductPublishingPage with selected-count display, Select All, and Clear actions. Single-item preview selection preserved independently. 15 new multi-select tests added (262 total feature_wordpress tests passing). No bulk writes introduced.

Stage 3B — List efficiency improvements ✅ COMPLETE

Merged feat/list-efficiency-improvements → main (2026-05-22). Added compact/standard view toggle (ListDensity enum), staleness detection (isStale(), staleCount() with 30-day threshold), keyboard navigation (selectNextDraft/selectPreviousDraft with wrapping), description snippet in standard card, and stale indicator icon. Updated ProductDraftCard with compact two-row layout variant and Flexible overflow handling. Page wires up Focus+onKeyEvent for arrow keys and density toggle button. 32 new tests added (294 total feature_wordpress tests passing). Stage 3 complete.

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.
