📝 Walkthrough

The form package adds a file-upload control with file-list binding, form integration, validation, file removal, accessible feedback, and responsive layouts. The change also adds translations, a file-size utility, Storybook examples, tests, and documentation, and adjusts tag icon alignment and text-field story labels.

Changes: File upload

Layer / File(s)	Summary
Public contract and form registration `src/tedi/components/form/file-upload/file-upload.types.ts`, `src/tedi/components/form/file-upload/index.ts`, `src/tedi/components/form/index.ts`, `skills/tedi-angular/references/forms.md`	Adds public file-upload types and exports. The form-control reference lists `FileUploadComponent` and its value type.
Selection, validation, and form state `src/tedi/components/form/file-upload/file-upload.component.ts`, `src/tedi/utils/file.util.ts`, `src/tedi/utils/index.ts`, `src/tedi/services/translation/translations.ts`, `src/tedi/components/form/file-upload/file-upload.component.spec.ts`	The control processes selections, validates and removes files, updates form state, and announces changes. The size utility formats byte values, and translations provide localized file-upload messages. Tests cover selection, validation, accessibility, and Angular form integration.
Rendering, styling, and usage examples `src/tedi/components/form/file-upload/file-upload.component.html`, `src/tedi/components/form/file-upload/file-upload.component.scss`, `src/tedi/components/form/_field-surface-mixins.scss`, `src/tedi/components/form/file-upload/file-upload.stories.ts`, `skills/tedi-angular/references/components.md`	Adds editable and read-only rendering, responsive styling, and Storybook examples. The component reference documents bindings, validation, and accessibility behavior.

Presentation updates

Layer / File(s)	Summary
Tag alignment and story labels `src/tedi/components/tags/tag/tag.component.scss`, `src/tedi/components/form/text-field/text-field.stories.ts`	The tag icon wrapper uses flex alignment and vertical centering. The “Default” and “Small” labels in the text-field size story use bold styling.

Merge Risk: 🔵 Low · up to dc023

A file marked valid can still display a rejection message. This is a bounded feedback issue; the PR is mergeable with a follow-up to keep the message in sync.

Security architecture risk: 🔵 Low · up to dc023

The new control selects and validates files but does not upload them or grant access to storage. Filenames and validation messages are rendered as text. No introduced security vulnerability was established, but receiving-service controls and downstream integration behavior remain outside the assessed scope.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The demonstrated exposure is selected file objects, form values and feedback in consuming browser applications. The component does not itself transport files or manage credentials or persistent storage; any tenant, service or data-store exposure depends on consumer upload integrations not established here.

Trust Boundaries and Controls

observed — Untrusted filenames and custom rejection messages reach text-only display sinks. Filenames use Angular interpolation; feedback text also uses interpolation; the root-level announcer assigns messages through textContent rather than HTML parsing.
inferred — Selection restrictions and mutable isValid flags provide application-side validation feedback, not proof that file content is safe or that an upload is authorized. The documented consumer-owned upload boundary is therefore decisive when interpreting these checks.

Resilience and Maintainability Implications

observed — Internal removal is blocked when the control is non-editable and emits per-file removal events after committing the remaining value. Consumers can use those events to abort their own upload work. Component destruction clears its pending selection-announcement timer.

Hardening Proposals

proposed — Make the integration guidance explicit that client-side file metadata and validity flags must not authorize uploads. Receiving services should independently enforce authorization, content policy and resource limits. This is a documentation proposal, not evidence that an existing receiving service lacks those controls.

an `afterEach` hook in the reactive-forms test suite, and remove the trailing
`jest.restoreAllMocks()` calls from both tests so cleanup also runs when an
assertion fails.
