-# Code Removal and Consolidation (LOC Reduction)
-
-Owner: Engineering  
-Document: code-removal-and-consolodation-spec.md  
-Revision: 2.0  
-Date: 2025-10-20
-Revision: 2.1  
-Date: 2025-10-25
-
-Purpose
-- Reduce lines of code (LOC) in this TS/Vue project (and any Python utilities) without changing behavior.
-- Remove dead/duplicate code, collapse pass-through layers, and slim public APIs.
-
-Success metrics
-- [ ] LOC reduced by 10–30% (cloc baseline vs. final).
-- [ ] Test coverage ≥ baseline; typecheck/lint clean.
-- [ ] Bundle size stable or lower.
-- [ ] No regressions in main user flows.
-
-Current status (2025-10-20)
-- Interim verification: typecheck and tests passing locally.
-- Consolidations completed in this pass (see checklist 4):
-  - Shopping request types centralized in sdk.
-  - UIShoppingListItem removed; grouping works on domain items with refs.
-  - Meals composable removed; toMealInput moved to decoders; components now import sdk directly.
-  - decodeLookup moved to decoders and reused.
-- Baseline metrics captured (cloc, coverage, build size):
-  - cloc saved: cloc.baseline.txt
-  - coverage saved (v8): coverage/ (see summary in terminal output)
-  - build size: dist size ~1.6M
-  - ts-prune saved: ts-prune.baseline.txt
-  - depcheck saved: depcheck.baseline.json
-
-Status update (2025-10-21)
-- Ran ts-prune and depcheck again to guide safe removals.
-- Notes:
-  - ts-prune doesn’t analyze .vue SFC imports, so exports used only by SFCs (e.g., dateformats.ago) appear unused; avoid removing those.
-  - Completed a safe API shrink: removed unused exports in domain (Maybe, NonNull) and decoders (decodeRecipes) without changing behavior.
-  - Removed an unused ref in MyShoppingPage.vue.
-  - depcheck flags core-js as unused; given Vue CLI/babel preset may rely on it for polyfills, defer removal for now.
-  - depcheck shows some devDependencies as unused but they are required by the Vue CLI toolchain; defer removal.
-  - Resolved typecheck errors after domain ref opt-in changes: updated ShoppingListItem.vue to remove person ref usage and guard optional ingredient access; TS + vue-tsc + tests pass.
-  - Verified end-to-end: lint PASS, typecheck PASS, vue-tsc PASS, tests PASS (no regressions).
-  - Reduced nullability in public SDK APIs where safe: getRecipe/getMeal/markMealConsumed/getCurrentShoppingList now return non-null and throw on errors; updated call sites accordingly.
-  - Domain decoders now return non-null and throw on invalid input (decodeRecipe/decodeMeal/decodeMealRecipe/decodeIngredient/decodeShoppingListItem/decodeShoppingList); list decoders return arrays.
-  - Lint/typecheck/vue-tsc/tests: all PASS after decoder contract tightening.
-  - Aggressive dependency cleanup: removed node-fetch and undici (unused in Node 18+), removed core-js (build and tests still PASS under current browserslist targets), and dropped Vite types from tsconfig. All checks and build PASS post-removal.
-
-Latest analysis artifacts (2025-10-21)
-- ts-prune (current): saved to ts-prune.current.txt; notable false-positives include dateformats.ago and units functions used inside SFCs.
-- depcheck (current): saved to depcheck.current.json; flags core-js and several dev deps as unused. These are likely required by Vue CLI/babel/coverage tooling; defer removal pending deeper validation.
-  - Follow-up result: Verified removal of core-js, node-fetch, undici did not impact tests/typecheck/build. Retained Vue CLI/Babel/coverage deps.
-
-Final verification snapshots (2025-10-25)
-- cloc.final.txt (exclude node_modules, dist, coverage): Files 100, Code 32,579; Vue SFC code 2,551; TS code 2,293.
-- Build size (Vue CLI): dist total ~1.6M; key bundles: chunk-vendors ~111KB (gz 40.9KB), app ~9.5KB (gz ~3.9KB).
-- Tests + coverage: 14 files, 27 tests, all PASS. Coverage stable on domain/sdk/units; SFCs not covered (unchanged behavior).
-- ts-prune refreshed (ts-prune.current.txt). Continue to treat SFC-only usages as false positives.
-
-Scope
-- In: TS/Vue app code, tests, configs, scripts; Python utilities if present.
-- Out: New features, architectural rewrites.
-
-Baseline and tooling (TS/Vue/Python)
-- Commands:
-  - JS/TS LOC: npx cloc . | tee cloc.baseline.txt
-  - Lint/typecheck: npm run lint && npm run typecheck
-  - Coverage: npm test -- --coverage
-  - Unused TS exports: npx ts-prune
-  - Unused deps: npx depcheck
-  - Search: rg (ripgrep)
-  - Bundle size (Vite): npm run build && du -h dist
-  - Python (if present): vulture . and coverage run -m pytest
-
-Acceptance
-- [ ] Baselines saved (LOC, coverage, bundle size).
-- [ ] CI green on main before starting.
-
-Ordered checklist (actionable)
-
-1) Baseline snapshot
-- [x] Run cloc; store cloc.baseline.txt.
-- [x] Run tests with coverage; store coverage report. (added dev dep @vitest/coverage-v8)
-- [x] Run npm run build; record dist size.
-- [x] Run ts-prune and depcheck; save outputs.
-
-2) Dead code inventory
-- [ ] ts-prune: list unused exports; verify via rg searches.
-  - [x] Refreshed ts-prune; review and mark SFC-used exports to avoid accidental removals.
-- [ ] Find unreferenced files:
-      rg -l "export default|export const|export function" |
-      while read f; do rg -q "(from|import).*$f" -g "!$f" . || echo "$f"; done
-- [ ] depcheck: identify unused deps/scripts.
-- [ ] Python (optional): vulture . for unused code.
-
-3) Delete proven dead code
-- [ ] Remove files/symbols with zero references.
-- [ ] Delete tests/mocks for removed code.
-- [ ] Fix imports; run lint, typecheck, tests, build.
-
-Acceptance
-- [ ] LOC decreased; CI green.
-
-4) Consolidate duplicated types and logic (repo targets)
-- Shopping requests
-  - [x] Export PurchaseExisting/PurchaseRefs (or a single request builder) from src/api/sdk.ts.
-  - [x] Reuse in src/composables/useShopping.ts; delete local duplicates.
-  - [x] Added PurchaseRequest union in SDK to simplify signatures and centralize request typing.
-- UIShoppingListItem mapping
-  - [x] Make itemsToGroups/uniqueMeals accept ShoppingListItemWithRefs.
-  - [x] Remove UIShoppingListItem and mapItemToUI; update callers.
-- Meals composable
-  - [x] Delete src/composables/useMeals.ts OR keep only toMealInput.
-  - [x] Move toMealInput to src/domain/decoders.ts if file removed.
-  - [x] Update components to import sdk directly for API calls.
-- Common decoder
-  - [x] Move decodeLookup<T>() to src/domain/decoders.ts; import in sdk.ts.
-- Component-local types
-  - [ ] Replace ad-hoc component types (e.g., MealCard.vue) with domain types.
-  - [x] Align ShoppingListItem.vue template/computed logic with domain changes (optional ingredient refs; removed person ref).
-- Unused refs
-  - [x] Remove unused reactive refs/vars (e.g., stray person ref in shopping pages if unused).
-
-Acceptance
-- [ ] Single source for purchase request types/builders.
-- [ ] One fewer UI-only item shape in shopping flow.
-- [ ] Meals API calls go through sdk; no pass-through wrappers.
-
-5) Shrink public API surface
-- [x] Export only used symbols from domain and sdk modules.
-- [ ] Remove unused overloads/params; prefer narrower interfaces.
-- [ ] Update re-exports; fix imports accordingly.
- - [x] Reduce unnecessary null/undefined on public SDK returns (getRecipe/getMeal/markMealConsumed/getCurrentShoppingList).
-  - [x] Narrowed visibility of internal helpers/types (listPersons made internal; PurchaseExisting/PurchaseRefs internal, union type exported).
-  - [x] Hide internal-only helpers/types: decoders.decodeMealRecipe/decodeShoppingListItem made module-private; units.UnitKey/equivalentUnits/Quantity/Total are no longer exported.
-
-Acceptance
-- [ ] ts-prune emits fewer/no unused export warnings.
-
-6) Simplify control flow and inline pass-throughs
-- [x] Inline trivial wrappers where applicable (meals composable removed; components call sdk directly).
-  - [ ] Prefer guard clauses over nested branches in remaining hotspots (audit pending).
-- [ ] Remove speculative extension points not used.
-- [ ] Replace small class-style modules with plain functions where LOC decreases.
-
-Acceptance
-- [ ] Complexity lower in touched files; tests unchanged.
-
-7) Test suite consolidation
-- [x] Remove duplicate tests (e.g., .js vs .ts duplicates), fixtures for deleted code.
-  - Removed tests/useAlert.test.js (duplicate of tests/useAlert.test.ts).
-- [ ] Ensure assertions are meaningful; avoid testing implementation details.
-- [ ] Keep or improve branch coverage on critical paths.
-
-Acceptance
-- [ ] Coverage ≥ baseline; runtime stable or faster.
-
-8) Dependency cleanup
-- [ ] Remove unused npm deps (depcheck) and scripts.
-  - [x] Refreshed depcheck results saved; plan conservative removals only after confirming toolchain needs.
-- [ ] Prefer stdlib/small helpers over heavy libs where equal.
-- [ ] npm prune && clean install; verify build.
-
-Acceptance
-- [ ] Smaller dependency graph; no new vulns; CI green.
-
-9) Docs and examples
-- [ ] Update README/ARCHITECTURE and code comments to reflect removals.
-- [ ] Document canonical modules replacing duplicates.
-- [ ] Add migration notes in CHANGELOG if applicable.
-
-Acceptance
-- [ ] Docs consistent; onboarding simpler.
-
-10) Final verification
- - [x] Re-run cloc; saved cloc.final.txt and noted summary.
- - [x] Re-run tests with coverage; all PASS; coverage consistent with previous runs.
- - [x] Re-run build; build size recorded in build-size.final.txt (dist ~1.6M).
-- [ ] Sanity test main user flows locally.
-
-Acceptance
-- [ ] All metrics at or better than baseline; no regressions.
-
-Quick command reference
-- LOC: npx cloc .
-- Typecheck: npm run typecheck
-- Lint: npm run lint
-- Tests + coverage: npm test -- --coverage
-- Unused TS exports: npx ts-prune
-- Unused deps: npx depcheck
-- Search: rg -n "<pattern>"
-- Build + size: npm run build && du -h dist
-
-Exit criteria
-- [ ] Target LOC reduction met with stable quality metrics.
-- [ ] Duplicates removed; canonical modules in place.
-- [ ] No pending deprecations awaiting removal.
-
-Next actions (clear, actionable)
-1) Capture baselines
-  - [x] Run cloc and save cloc.baseline.txt
-  - [x] Run tests with coverage and save report summary
-  - [x] Build app and note dist size
-  - [x] Run ts-prune and depcheck; save outputs
-2) Component type audit
-  - [ ] Replace any ad-hoc component types with domain types (scan components/*)
-3) Unused refs/vars cleanup
-  - [x] Scan shopping/meals components for unused refs/variables; remove
-4) Shrink public API surface
-  - [x] Use ts-prune results to remove unused exports in domain and sdk
-  - [ ] Second pass: validate remaining ts-prune hints against .vue usage; prune safely
-  - [ ] Consider reducing parseRecipe nullability (throw on parse failures) if UI updated accordingly
-5) Test suite consolidation
-  - [x] De-duplicate tests with .js and .ts counterparts (e.g., prefer TypeScript)
-6) Dependency cleanup
- - [x] Remove unused npm deps (depcheck) and scripts (removed core-js, node-fetch, undici, @babel/eslint-parser). Verified tests/typecheck/build PASS.
-7) Final verification
-  - [ ] Re-run cloc/tests/build; record deltas vs. baseline; sanity test user flows
-  - [x] Interim verification after dep cleanup: tests/typecheck/vue-tsc/lint/build PASS
-
-Additional targeted opportunities (2025-10-25)
-- Simplify env typings: removed Vite-specific triple-slash reference and duplicate ImportMeta declarations; kept a minimal optional ImportMetaEnv in `src/env.d.ts`. All checks PASS.
-- Component type audit: migrated `MealCard.vue` to domain `Meal` type with null guards. Remaining spots use purposeful `Pick<>` types; can leave as-is unless standardizing is preferred.
-- ts-prune: refreshed; remaining flags are either used by SFC templates or part of public SDK surface. No further safe removals identified without deeper UI refactors.
-
-Cleanup (completed)
-- Removed intermediate artifacts committed for this consolidation pass:
-  - cloc.baseline.txt, cloc.final.txt
-  - build-size.final.txt
-  - ts-prune.baseline.txt, ts-prune.current.txt
-  - depcheck.baseline.json, depcheck.current.json
-  - coverage/ directory
-- Removed coverage script and plugin from package.json:
-  - scripts: deleted `test:coverage`
-  - devDependencies: removed `@vitest/coverage-v8`
-- All quality gates remain PASS after cleanup.
