React

Used existing UI components and server-action patterns to display saved passages, source links, dates, and explicit sparse or error states. No component-model friction was evident in the record.

Extended the existing invoice form with photo selection, preview, reading state, confidence messaging, and editable fields for scanned values. Draft lifting through props kept review-before-save intact and the production build passed.

What worked

Component state and prop lifting made unsaved drafts and user corrections straightforward.

Rendered donor passages with source links, seen dates and age, plus explicit almost-nothing and warning states so empty results never looked like missing data.

What worked

Component model made found, sparse, warning, and re-check states straightforward to display.

Updated the invoice form to support photo selection, draft prefill, photo preview, confidence display and explicit review messaging with save only on user confirmation.

What worked

Component state and conditional review display made it easy to keep low or missing values editable and avoid accidental saves.

Used the existing component model to replace hard-coded interface text with locale dictionaries and locale-aware date and euro formatting. Context-based locale switching and persistence worked as expected and the production build succeeded.

What worked

Component composition made string replacement straightforward and locale provider integration required no extra dependencies.

Relied on the component framework already used by the app to add a locale provider, translation hook, language switcher, and locale-aware amount and date formatting. The small app size made a dependency-free context plus dictionary approach sufficient.

What worked

Context and hooks cleanly replaced hardcoded formatting and strings without requiring an external internationalization library.

Extended the existing form and added a scan component so extracted values prefill editable fields with warnings for uncertain items. Nothing saves until explicit submit.

What worked

Component model made prefill plus manual review straightforward without changing the save path.

Built a floating voice panel with status, transcript, proposal confirm and cancel, and undo, wired to existing cart state. State updates and conditional UI behaved as expected during browser verification.

Extended the invoice form and list for file attachment, editable extraction draft, totals mismatch warning, and original-image preview. Frontend build succeeded; interactive browser behavior was not exercised in the record.

What worked

Component extension supported side-by-side draft review and manual fallback entry without changing the overall app structure.

Existing component structure made it straightforward to replace hardcoded strings with translation calls and add a language switcher. No framework-level problems were encountered.

What worked

Component model kept translation changes localized and reviewable.

Built signing forms, status cards, and blocked-approval notices with existing UI primitives. Component reuse kept the new states consistent and compile-time behavior was clean.

What worked

Existing form and feedback components covered signing, status display, and blocked states without new design work.

Built capture input, uncertain-field highlighting, duplicate blocking, and prefill into the existing invoice form. Server-side rendering check confirmed expected UI elements.

What worked

Component state made draft review and reuse of scanned values straightforward.

Used component state and memoization to implement instant text search with normalization and typo tolerance, plus teacher selection, a one-off toggle, result count, empty state, and clear action. Logic probes passed, but interactive keystroke behavior was not exercised for lack of a browser.

What worked

State plus memoized filtering kept the implementation small with no new dependencies; normalization and edit-distance fallback handled misspelled names in logic checks.

Built small client components for the analytics provider, fire-and-forget view events, and a booking form wrapper that records start intent before the existing server action runs.

What worked

Client component boundaries and form submit handling made it easy to isolate tracking from booking behavior.

Used for the client chat panel state and submission flow against the new assistant route. Existing styling conventions were easy to follow; no live browser rendering check was performed.

What worked

Chat hook handled message state and submission with little custom code.

Relied on server and client components for translated pages, header, class cards, and language switcher across English, Spanish, and Portuguese.

What worked

Server component translation flow and shared UI components adapted cleanly to localized rendering.

Extended the existing invoice UI with a photo capture, preview, editable draft with confidence indicators, and explicit save or discard actions reusing current validation.

What worked

Component model fit the draft-review flow well and the production build confirmed the UI compiled cleanly.

Relied on the existing React frontend as the built artifact for private hosting. No UI changes were needed; the production build completed and the app root served correctly in smoke checks.

What worked

No frontend changes were required to support the same-origin private hosting plan.

What got in the way

Visual browser verification was not possible in this environment.

Used server and client components for localized layouts, a language switcher, and email templates carrying an explicit locale for rendering outside request context.

What worked

Explicit locale threading through templates and helpers kept rendering predictable across component types and background workers.

Relied on existing components plus a small language context for translation lookup, persistence, and locale-aware currency and date formatting. No extra internationalization library was needed for the small string set.

What worked

Context plus browser internationalization APIs covered switching, interpolation, and per-language euro rendering with minimal code.

Built the chat thread with subscription handling, deduplication by id, and send state in a client component. Ordering and sender display behaved as expected in the successful production build.

What worked

Effect subscription with cleanup and id-based dedup was straightforward to express.

Relied on the existing component UI as the surface for localization, replacing static labels, form text, lists, and totals with translated keys. No framework upgrade or restructuring was needed.

What worked

Component structure made it easy to find every user-visible string and swap in translated values.

Built one shared functional component for the map card and rendered it in two existing routes. Props-free reuse kept the change small and consistent.

What worked

Component reuse across pages worked cleanly with no added dependencies.
