The bar's chip clicks POST a payload shaped as `predicates: {<source>:
<per-source>}` — flat, one entry per data source. Go declared
`Predicates map[DataSource]Predicates` — a doubled-nested wrapper where
each map value was itself a Predicates struct with named per-source
fields. The JSON shape Go expected was
`{"deadline": {"deadline": {"status": [...]}}}`; the shape the bar
emitted was `{"deadline": {"status": [...]}}`. Go silently unmarshalled
the bar's payload as `Predicates{}` (all source fields nil), so every
chip click on /views/any was a server-side no-op — the regression in
#115.
The latent contract bug was present since t-paliad-144 A1 (b516201) but
only surfaced now: /inbox uses the InboxSystemView's code-resident
predicates (built in Go directly, doubled shape works) and saved views
never carried predicates in the DB, so chip-click overlays were the
only path that exercised the wire-format wrong way. /views/any made
that path visible because all four sources need narrowing.
Fix: align Go to the flat shape the frontend already emits.
- FilterSpec.Predicates: `map[DataSource]Predicates` → `*Predicates`.
- All `spec.Predicates[SourceX]` access sites in view_service.go +
approvalStatusMatches + allowed* helpers + system_views literals
+ tests rewritten to `spec.Predicates.X` with a nil-spec.Predicates
guard.
- Frontend FilterSpec.predicates type tightened from
`Partial<Record<DataSource, Predicates>>` (which silently allowed
the wrong runtime write) to `Predicates`.
Regression coverage:
- `filter_spec_predicates_test.go` (new, Go) pins three contracts:
the bar's exact wire payload unmarshals into a non-nil per-source
predicate; marshalling a Go-constructed spec produces the same flat
shape; the "Erledigt" chip's request narrows to completed deadlines.
- `compute-effective.test.ts` (new, bun:test) pins 12 chip-overlay
cases for /views/any (every axis the saved view's sources expose).
Build hygiene:
- `go build ./...` clean.
- `go test ./... -count 1` clean (existing inbox + filter_spec tests
updated for the new struct shape; new tests pass).
- `cd frontend && bun run build` clean.
- `cd frontend && bun test src/` — 169 pass, 0 fail.
No migration: paliad.user_views.filter_spec jsonb rows live with
`predicates: {}` or no predicates field; both unmarshal as nil
*Predicates under the new type, identical to the no-narrowing behaviour
the old map type produced for the same rows.
