Cleared 4 rule buckets (37 violations, including 5 real bugs) and
silenced 1 informational bucket from the Next 16 / react-hooks v7
upgrade. Cleared rules promoted from `warn` back to `error` so new
regressions block CI.
Real bug fixes:
- `interest-contact-log-tab.tsx`: `useMemo` used for side effects
(5 setState calls inside a memo body); converted to `useEffect`.
- `PieChart.tsx`: cumulative `let angle` mutation in a render-phase
`map`; converted to `reduce` so the slice array is built without
re-assignment.
- `documents-hub.tsx`: `useMemo(() => ({ count: 0 }))` used as a
mutable drag counter; converted to `useRef`.
- `notes-list.tsx`: `Date.now()` read during render for note-edit
countdown (impure) → pinned to a `now` state ticked every 30s.
- `onboarding-checklist.tsx` / `user-profile.tsx` /
`user-settings.tsx`: `useEffect(() => void load(), [])` with the
`load` function declared AFTER the effect — relied on hoisting,
trips Compiler's "access before declared" rule. Declared inside
the effect.
Pattern fixes (intentional cache-via-ref → state or layout-effect):
- 6 `ref.current = x` writes during render moved into layout
effects (`use-realtime-invalidation`, `settings-form-card`,
`inbox`).
- 3 `ref.current` reads during render (search totals cache,
scanner file ref) rewritten to backed-by-state.
- `use-is-mobile.ts` rewritten on `useSyncExternalStore` to avoid
the SSR-then-rehydrate setState dance.
- `use-notifications.ts` rewritten to write socket pushes directly
into the React Query cache via `setQueryData`, removing a local
state mirror.
Rule config (`eslint.config.mjs`):
- `react-hooks/purity` → error (was warn, cleared)
- `react-hooks/set-state-in-render` → error (was warn, cleared)
- `react-hooks/immutability` → error (was warn, cleared)
- `react-hooks/refs` → error (was warn, cleared)
- `react-hooks/incompatible-library` → off (informational only)
- `react-hooks/set-state-in-effect` → warn (51 remaining, all the
useEffect→fetch→setState data-fetch pattern; migration to
useQuery tracked in BACKLOG)
Verified: tsc clean, eslint 0 errors / 69 warnings (down from 105),
vitest 1315/1315, next build green.

Replaces every em-dash and en-dash with regular ASCII hyphens
across comments, JSX strings, and dev-facing logs. Mostly cosmetic
but stops the inconsistent mix that crept in over the last few
months (some files used em-dashes in comments, others didn't,
some used both).
Bundles two small dashboard-layout tweaks that touch a couple of
already-modified files:
- (dashboard)/layout.tsx main padding goes from p-6 to pt-3 px-6
pb-6 so page content sits closer to the topbar.
- Sidebar now receives the ports list it needs for the footer
port switcher.
