Here is the analysis.\n\n---\n\nType: MultiSelectDropdownProps\n\nFile: /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records-ui/src/components/MultiSelectDropdown/MultiSelectDropdown.tsx\n\nInvariants Identified\n\n- label must be a non-empty string (used as accessible name for the combobox and as the popup's aria-label; an empty string would silently break accessibility)\n- values must be an array of strings (never null, never undefined)\n- Every value in values is expected to correspond to an entry in options, though mismatches are handled gracefully at render time\n- options carries the full display/identity contract via the imported Option shape ({ label, value, disabled? })\n- onToggle is called with a single option's value string; callers own the add/remove logic\n- onClear resets the entire selection; the component itself calls close() after it\n\nRatings\n\n- Encapsulation: 8/10\n The type exposes exactly what callers need and nothing of the internal open/search/displayLabel machinery. triggerId, popupId, isOpen, searchQuery, and displayLabel are all owned by the component and never surface outward. The private sub-component types (TriggerProps, PopupProps, etc.) are unexported, which keeps the module boundary clean.\n\n- Invariant Expression: 6/10\n label: string permits an empty string with no type-level signal that this breaks accessibility. values: string[] communicates no constraint on what those strings represent — whether they must be a subset of options, or whether duplicates are permitted. onToggle: (value: string) => void communicates that the callback receives one string but not that it should be a value from the known option set. These constraints exist in the runtime behaviour and in tests, but not in the type.\n\n- Invariant Usefulness: 9/10\n The split of onToggle (single-item toggle) and onClear (reset) cleanly separates two semantically distinct operations. Using string[] rather than Option[] for values is a deliberate and good choice: it decouples selection state from display data, which is the correct direction for a controlled component.\n\n- Invariant Enforcement: 7/10\n values is never mutated internally — the component is correctly controlled. onClear always calls close() unconditionally, which is the right side-effect encapsulation. There is no guard against an empty label string, and there is no deduplication of values before passing them to sub-components, so a caller supplying ['A', 'A'] would double-count in the +N summary label.\n\nStrengths\n\n- The controlled/uncontrolled boundary is unambiguous: the parent owns values, the component owns isOpen and searchQuery. This makes state ownership obvious and prevents the common anti-pattern of mixing controlled and internal selection state.\n- Separating onToggle and onClear as distinct callbacks rather than a single generic onChange: (values: string[]) => void is a meaningful design decision — it prevents the parent from having to implement the toggle logic, though in this PR the factory (createNhrDocumentCategoryFilterConfig) does implement the toggle logic anyway, which is a tension worth noting.\n\nConcerns\n\n1. label: string is structurally too wide. An empty string silently produces a combobox with no accessible name, which is a WCAG violation the type will never catch.\n2. No deduplication: values: ['A', 'A'] renders Report A, +1, which is a misleading summary label.\n3. The displayLabel computation inside the component (options.find((o) => values.includes(o.value))) orders the first displayed label by options array order, not by insertion order. This is intentional (and tested), but the type gives no hint of this ordering contract to callers.\n\nRecommended Improvements\n\n- Change label to a branded or refined type, or at minimum document the non-empty contract with JSDoc, so consumers can't silently pass empty strings:\n / Must be a non-empty string; used as the combobox accessible name. */\n label: string\n\n- Consider whether onToggle should stay or whether a onChange: (values: string[]) => void design is simpler end-to-end. Because createNhrDocumentCategoryFilterConfig re-implements the toggle logic anyway (add/remove logic is in the factory, not in the component), the current split pushes responsibility to every consumer. A single onChange callback receiving the new string[] array would make the component more self-contained.\n\n---\n\nType: MultiSelectDropdownTriggerProps\n\nFile: /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records-ui/src/components/MultiSelectDropdown/MultiSelectDropdownTrigger.tsx\n\nInvariants Identified\n\n- triggerId and popupId must be non-empty strings matching real DOM element IDs (they flow directly into id= and aria-controls=)\n- displayLabel is the computed summary string visible when closed; it may be empty (no selection)\n- searchQuery is the live filter text visible when open; it may be empty\n- isOpen determines which of displayLabel and searchQuery is shown as the input value, and controls readOnly\n- hasValues determines whether the clear button renders; it must stay in sync with values.length > 0 from the parent — this is a derived boolean that creates a potential redundancy\n- onInputChange is only meaningful when isOpen is true; calling it when isOpen is false is allowed by the type but would be a no-op or incorrect\n\nRatings\n\n- Encapsulation: 6/10\n This type is internal (not exported from the package index), which is correct. However, it carries a significant amount of pre-computed state that is derived from the parent's internal state (displayLabel, searchQuery, hasValues). The type is tightly coupled to a specific rendering strategy — the parent owns the open/search state and projects derived properties down rather than letting the trigger compute them. This is defensible for performance and testability but means the trigger's type expresses infrastructure-level concerns rather than semantic ones.\n\n- Invariant Expression: 4/10\n displayLabel: string and searchQuery: string look identical to TypeScript — nothing in the type communicates that exactly one of them is shown at a time based on isOpen. The hasValues: boolean field is a derived value that must stay consistent with the parent's values.length > 0; if these get out of sync the clear button will show incorrectly. The type cannot express this consistency requirement.\n\n- Invariant Usefulness: 6/10\n The props are granular and allow the trigger to be tested in isolation (as the tests do), which is valuable. But the prop surface is wider than necessary for a component that is never used outside of MultiSelectDropdown.\n\n- Invariant Enforcement: 5/10\n No guards exist. hasValues and displayLabel could contradict each other (e.g., hasValues: true but displayLabel: ''). Since this is an internal component with a single caller, the risk is low today, but it is a latent inconsistency hole.\n\nStrengths\n\n- The type is unexported, which correctly restricts it to the module boundary.\n- The separation of displayLabel (closed state) and searchQuery (open state) into two fields rather than a single value that switches meaning is clear and avoids a conditional union.\n\nConcerns\n\n1. hasValues: boolean is a derived fact already available from displayLabel !== '' in the closed state, or from the parent's values.length. Having a separate boolean creates a two-source-of-truth situation.\n2. The type is 10 props wide, which is a sign that the component is doing too much, or the parent is decomposing state too eagerly and projecting all of it down.\n\nRecommended Improvements\n\n- Remove hasValues and derive it in the trigger from displayLabel !== ''.
