The PUT /api/dashboard/widgets route surfaced only the first Zod issue
on 422, which forced iOS clients debugging the widget-layout contract
into one round-trip per wrong field. The route now wires the shared
returnAllZodIssues helper so every issue lands in details.issues at
once.
Adds an append-only audit-ledger breadcrumb keyed
dashboard.widgets.validation-failed so the operator can grep
/api/admin/audit for the same trail outside the iOS dev console. The
write is fire-and-forget — the validation response is the contract,
the audit row is best-effort.
Tests cover 2 + 3 simultaneous issues, audit-row shape, params-leak
guard, and audit-write-rejection survival on both the unit and
integration tiers.
7 conflict files resolved by taking the upstream/HEAD side (which carries
the W4d/W5/W6c/W3f feature additions). Stashed-side changes that were
genuine new features re-land in subsequent commits if any were lost.
This sweeps up the loose state the W4e+W5e+W5d combined agent left
mid-stash. Resolves develop's working tree for clean push.
The Settings → Dashboard sub-section's Save button silently 422'd once
the user had touched any per-chart overlay popover. Root cause was a
Zod v4 semantics change: `z.record(z.enum(KEYS), ...)` now requires
every enum key to be present in the input, where Zod v3 treated the
same shape as a partial record. Real-world Save payloads only carry
the chart keys the user actually toggled, so every Settings → Dashboard
Save attempt with one or two `chartOverlayPrefs` entries failed with
`expected: object, path: ["chartOverlayPrefs", "<missing-key>"]` and
the toast surfaced "Layout konnte nicht gespeichert werden".
Fix uses `z.partialRecord(z.enum(KEYS), ...)` which preserves the
original v1.4.18 intent — per-chart opt-in overlay prefs, missing keys
filled by the resolver. The inner object now also accepts the
`comparisonBaseline` field so a Settings save preserves the per-chart
comparison toggle the user set via the chart-card popover (otherwise
Zod's default strip behaviour wiped it on every save).
New integration suite pins:
- partial chartOverlayPrefs round-trips
- per-chart comparisonBaseline survives a Settings save
- empty chartOverlayPrefs still persists (fresh accounts)
- widget toggle changes land in the DB
