Accessibility work on the UI layer, all of it rooted in one structural gap:
there were no form primitives, so every field was hand-assembled and every
field got the same details wrong.
Form primitives
- components/ui/Field.tsx (Field/TextField/SelectField/TextareaField) and
Button.tsx. Field generates the control id with useId and derives htmlFor
from it, which is what makes the association impossible to omit rather
than merely conventional.
- 92 labels existed, 4 used htmlFor, and no input carried an id at all: a
screen reader announced an unnamed edit box and clicking a label focused
nothing. Now every label resolves to its control (0 unassociated), and the
input class chain that appeared verbatim 85 times appears zero times.
- Field also takes a render prop, so Lookup, CountryPicker and Picklist get
the same wiring instead of a second, partial solution.
- SearchInput replaces three hand-rolled copies of the icon-in-a-box search
whose input had only a placeholder — not a label — and killed its own
focus ring with outline-none and nothing in its place.
- Toggle groups (workdays, reorg change type) became fieldsets with
aria-pressed; colour alone was carrying the selected state.
Comboboxes
- Lookup and CountryPicker were text inputs with a div of clickable buttons
underneath: typeable, but no keyboard path to a result and nothing telling
a screen reader a list had appeared. Both now carry role=combobox,
aria-expanded/controls/activedescendant and listbox semantics, with arrow
keys, Enter and Escape. Escape stops propagation, or it would close the
surrounding dialog along with the dropdown.
Dialogs
- useDialogFocus centralises what Modal and SlideOver each owed the
keyboard and neither provided beyond Escape: focus into the dialog on
open, Tab and Shift+Tab cycling within it, focus restored to the trigger
on close.
- SlideOver stays mounted for its transition, and aria-hidden does not
remove anything from the tab order — so every closed panel was leaving
invisible tab stops at the end of the page. `inert` fixes that.
Route states
- loading.tsx, error.tsx, not-found.tsx and global-error.tsx. Every page in
the (app) group is server-rendered per request, so without loading.tsx a
navigation showed nothing at all until the server answered, and a render
error dropped the user on Next's own screen with no way back.
Tests
- 22 component tests (vitest jsdom project). Two of them found limits of the
environment rather than of the code: jsdom implements neither `inert` nor
scrollIntoView, so the inert test asserts the attribute and the missing
scrollIntoView — which was taking the whole render down from inside an
effect — is stubbed in the setup file.
Positions
- Removed the "Besetzen" action, the StaffInternallyModal behind it and the
now-unreachable staffPositionInternally server action: a position is filled
through the hire process, not from the positions list. Note that
transfer_employee has no position_id at all and never touched `positions`,
so with staff_position_internally out of the UI, hire_employee is the only
thing that closes a position — a transfer into an open one leaves it open.
The RPC itself is still in the database and still covered by its tests.
SVNR
- Austrian social security numbers are now validated: ten digits, weighted
check digit mod 11, and the TTMMJJ tail cross-checked against birth_date,
which is what catches a transposed date that a valid check digit would let
through. A serial whose weighted sum lands on 11 is rejected rather than
wrapped — those are never issued.
- Applies to Austrian locations only; the German/Czech/Slovenian equivalents
have their own formats and stay free-form.
- Enforced by a trigger, not inside hire_employee/change_employee_data, for
the same reason as the assignment history: both have been redefined by
half a dozen migrations. Only a *newly written* value is checked, so a
legacy number never blocks an unrelated transfer or address change.
- The seed drew a random four-digit prefix, so its check digit was right
only by chance and every seeded Austrian row would now be rejected;
it computes the check digit properly now.
Tech stack
- next 16.2.11 closes nine advisories against 16.2.10, including a
middleware/proxy bypass in App Router apps on Turbopack — proxy.ts is this
app's entry gate. RLS remains the real boundary, so the blast radius was a
blank page rather than data, but it is a patch-level fix. Also react
19.2.8, tailwind 4.3.3, lucide-react 1.26, supabase-js/ssr, postcss.
- CI runs lint, typecheck, schema/type drift, tests and build; a second job
replays every migration onto an empty database and runs the integration
suite against it, so a migration that cannot be replayed from scratch
fails here instead of during a restore.
- scripts/check-schema-types.mjs diffs the hand-written lib/supabase/types.ts
against the migrations. Reading the SQL rather than a live database keeps
Postgres out of the fast CI job. Verified in both directions.
- vitest now runs two projects: node for logic, jsdom for components. The
first component test covers the org chart expand control, which broke
earlier this session when elementsSelectable={false} made React Flow
compute pointer-events:none for the whole node; re-introducing that prop
fails three of these tests.
- Content-Security-Policy is emitted report-only. Enforcing a policy derived
from inspection rather than from violation reports risks blanking the app;
'unsafe-inline' on script-src is required until a nonce is threaded through
proxy.ts, which is a separate change.
- Fixed supabase/seed.ts, which this session's SVNR change had broken: the
extensionless "../lib/svnr" import does not resolve under Node's ESM
loader, so the seed failed at startup.
- engines pinned to node >=22 <25, tsconfig target ES2022, and the dead
test:e2e script removed (no Playwright is installed).
