## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Instance settings collect deployment-wide controls; one of them was
the Heartbeats page, an instance-wide list of scheduler heartbeat agents
with enable/disable toggles
> - The same controls live on each agent's own configuration surface, so
the standalone list duplicates them, and its framing no longer matches
how heartbeat agents are managed
> - Keeping a settings view that no longer makes sense costs every
deployment navigation noise and maintenance
> - This pull request removes the page, its route, its navigation
entries, and its hidden-settings key for all deployments
> - The benefit is a smaller, coherent settings surface, with operator
hidden-settings lists that still mention the retired key continuing to
work unchanged
## Linked Issues or Issue Description
No public issue exists; describing the issue inline per the enhancement
template:
**What existing behavior does this improve?**
The instance settings surface — specifically the Settings → Heartbeats
page, which listed scheduler heartbeat agents instance-wide with
enable/disable toggles. The view no longer makes sense as a standalone
settings page: the same controls are available on each agent's
configuration surface, and the instance-wide list framing does not match
how heartbeat agents are managed.
**Subsystem affected**
Cross-cutting: `ui/` (page, route, navigation), `packages/shared`
(settings-visibility registry), docs.
**Current behavior**
The page renders at `/company/settings/instance/heartbeats`, appears in
the settings sidebar and tab bar, and is hideable by hosting operators
via the `instance.heartbeats` key of `PAPERCLIP_HIDDEN_SETTINGS`.
**Proposed behavior**
The page, route, and navigation entries are removed for every
deployment. The `instance.heartbeats` registry key is retired; operator
lists that still send it are logged and ignored, so mixed-version fleets
keep working. Remembered settings paths pointing at the old page remap
to the settings root. Heartbeat APIs are unchanged.
**Reason and benefit**
A smaller, coherent settings surface with no duplicated controls; less
navigation noise and maintenance for every deployment.
**Breaking changes**
None functional. Bookmarks and remembered paths to the removed page land
on the settings root; `PAPERCLIP_HIDDEN_SETTINGS` lists that still
include `instance.heartbeats` log a warning and are otherwise honored
unchanged.
## What Changed
- Deleted `ui/src/pages/InstanceSettings.tsx` (the Heartbeats view) and
its route in `ui/src/App.tsx`.
- Removed the sidebar entry (`CompanySettingsSidebar`) and tab-bar item
(`CompanySettingsNav`).
- Removed `"/heartbeats"` from the remembered-settings-path allowlist;
remembered heartbeats paths now remap to the settings root.
- Retired the `instance.heartbeats` key from the shared
settings-visibility registry and the environment-variables doc;
documented that retired keys are ignored with a warning.
- Dropped the now-unused UI client wrapper for the instance
scheduler-agent list (`heartbeatsApi.listInstanceSchedulerAgents`); the
server endpoint stays.
- Removed the unused `schedulerHeartbeats` query key.
## Verification
- `npx vitest run packages/shared/src/settings-visibility.test.ts
ui/src/lib/instance-settings.test.ts
ui/src/components/CompanySettingsSidebar.test.tsx
ui/src/components/access/CompanySettingsNav.test.tsx` — 24 tests
passing.
- Full `ui` vitest suite: 4426 tests, 4 failures — all in files this PR
does not touch; 3 were load-induced timeouts that pass on rerun, and
`OnboardingWizard.test.tsx` "renders instead of throwing when the
browser denies storage access" fails identically on a clean master
checkout (pre-existing).
- `pnpm --filter @paperclipai/ui typecheck` and `pnpm --filter
@paperclipai/shared typecheck` — clean.
- Merged `master` to clear a conflict (see below) and re-ran the four
focused suites (24 passing), `ui/src/App.test.tsx` and
`ui/src/plugins/bridge.test.ts` (22 passing), and both typechecks — all
clean. Full CI is green on the merge commit.
## Merge With master
`master` gained the `company` → `organization` copy pass (#12243), which
reworded strings inside `ui/src/pages/InstanceSettings.tsx` — the page
this branch deletes — producing a modify/delete conflict. Resolved by
keeping the deletion: the page is going away, so the rewording of its
copy has nothing to apply to. Every other file merged cleanly, and
`master`'s rewording in `App.tsx`, `App.test.tsx`, and
`CompanySettingsSidebar.tsx` sits away from this branch's structural
removals, so both changes survive. The net diff against `master` is
unchanged from the pre-merge review: the same 13 files, 23 insertions,
330 deletions.
## Risks
- Low. Pure removal of a UI surface; heartbeat data and APIs are
untouched. Operators still listing `instance.heartbeats` in
`PAPERCLIP_HIDDEN_SETTINGS` get a warning log and otherwise unchanged
behavior (covered by the registry's unknown-key handling). Bookmarks and
remembered paths to the old page land on the settings root.
