Nicky LeachandClaude Opus 5.5 83c6832ccb fix(build): typecheck package, Playwright, and e2e test files in CI (#18839)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Runner, plugin, and Playwright tests verify how those agents run,
connect, and appear in the board
> - Most package tsconfigs exclude tests, and Vitest strips types, so a
type error in those tests fails nothing
> - The tests drifted to 803 real type errors, and some of those errors
hid assertions that checked nothing
> - paperclipai/paperclip#18739 and paperclipai/paperclip#18738 check
the server test tree and four test projects, but not these files
> - This pull request adds a required check for these test files, fixes
every error, and fails CI if a test file is in no program
> - The benefit is that a type error in any test file outside
`server/src` now fails CI

## Linked Issues or Issue Description

Refs #18738

**What happened?**

517 test files were in no program that required CI checks. A type error
in those files did not fail CI.

**Expected behavior**

CI fails on a type error in any test file.

**Steps to reproduce**

Add `export const value: number = "text";` to a test file under
`packages/paperclip-runner/src` on master. CI stays green, because
`tsconfig.json` excludes test files and Vitest strips types.

**Measured gap**

Each row is a program with its tests included, on one thread. File and
error counts are for head `7d4b5e907a`. Memory peaks were measured
before the two latest merges of master.

| Group | Test files | Real errors | Peak |
| --- | ---: | ---: | ---: |
| `paperclip-runner` Node source | 290 | 644 | 1.09 GiB |
| `paperclip-runner` surfaces | 9 | 12 | 0.42 GiB |
| `paperclip-runner` devtools and examples | 14 | 0 | 0.68 GiB |
| `sandbox-providers/kubernetes` | 21 | 65 | 0.44 GiB |
| 8 other sandbox providers and `bridge-template` | 32 | 4 | 0.34 GiB |
| `plugins/sdk` | 22 | 15 | 0.41 GiB |
| `plugin-workspace-diff` | 5 | 0 | 0.37 GiB |
| `plugin-orchestration-smoke-example` | 1 | 1 | 0.15 GiB |
| `kv-demo-mcp-server` | 3 | 0 | 0.13 GiB |
| `packages/db` scripts | 1 | 0 | 1.01 GiB |
| 8 Playwright suites under `tests/` | 52 | 25 | 1.72 GiB |
| `tests/runner-acceptance` | 3 | 0 | 0.58 GiB |
| `tests/e2e`, through layer declarations | 63 | 37 | at most 1.59 GiB |
| `ui` `AttentionInteractionResolver.test.tsx` | 1 | 0 | n/a |
| **Total** | **517** | **803** | |

27 of the 803 errors came from master while this pull request was open.
Each merge of master brought new test code that no check had read.

Errors that were config errors, not real errors:

- One TS2688 for each provider, because the root install does not
install provider dependencies.
- 9 in the Runner Node program (TS7016 and TS6059).
- 2 in `tsconfig.browser.json`. TypeScript 7 removed `baseUrl`, so that
config was invalid.
- 213 in the Playwright suites (`@/*` aliases and Vite types).
- About 60 in `tests/e2e` (import extensions and aliases).

`packages/plugins/create-paperclip-plugin` has no gap. Its tsconfig
excludes its test, but `cli/tsconfig.json` reaches that test through an
import. `server/test-baselines` also has no gap, because
`tests/lifecycle-baseline` reads it.

## What Changed

- Added `scripts/typecheck-test-programs.mjs` and its tests. The
`Typecheck + Release Registry` job runs it. It checks each program in
`PROGRAMS` on one thread.
- The script fails if a tracked `*.test.ts(x)` or `*.spec.ts(x)` file
outside `server/src` is in no program. The compiler file list decides
this, because `include` drops `foo.test.tsx` when `foo.test.ts` exists.
- Added a `tsconfig.test.json` to each uncovered package, and
`tests/tsconfig.playwright.json`.
- Added `tests/e2e` to `PROJECTS` in
`scripts/typecheck-test-projects.mjs`, with a `tsconfig.json` and a
`tsconfig.layers.json`.
- Added `scripts/typecheck-sandbox-providers`. It is a small workspace
that installs provider SDKs from one lockfile. I did not add a lockfile
inside each provider, because
`scripts/build-standalone-public-packages.mjs` uses a frozen install
when one exists, and that changes what a release resolves.
- Corrected `packages/paperclip-runner/tsconfig.browser.json` for
TypeScript 7.
- Set `rootDir` to `..` in
`packages/paperclip-runner/tsconfig.test.json`, because one Runner test
imports from `packages/adapter-utils/src`. The program does not emit
files, so this changes no build output.
- Moved the Kubernetes provider from `vitest ^3.2.4` to `^4.1.8`, the
version the other providers use. Vitest 3 requires `tinypool ^1.1.1`,
which has two critical advisories (GHSA-85c8-ppgw-ccpr and
GHSA-5gmw-xhrv-c9v3). The first patched version is 2.1.2. Its tests have
the same result on both versions: 189 passed, and the same 12
`file-sync` tests failed.
- Moved the Kubernetes provider from `zod ^3.24.2` to `^4.6.6`, and gave
its two `z.record` calls a key schema. This is the only production
change, and it stays in this pull request. See "Production change for
review".
- Renamed `AttentionInteractionResolver.test.ts` to
`AttentionInteractionResolver.replace.test.ts`, so TypeScript reads the
`.test.tsx` beside it.
- Fixed all 803 errors, with changes to test files and test support
only. The fix for `contracts/native-execution.test.ts` is the same as
the fix in paperclipai/paperclip#18739, so those two changes merge
cleanly.
- Updated `doc/DEVELOPING.md`.

This pull request does not edit `server/scripts/typecheck-layers.mjs`.
paperclipai/paperclip#18739 and paperclipai/paperclip#18738 have both
merged, and this branch includes them.

### Production change for review

The new lockfile made dependency review flag `zod@3.25.76` as a
high-severity advisory (GHSA-mrhx-c7xc-m3w5). The first patched version
is 4.6.6, so 3.x has no fix. The published Kubernetes plugin uses zod to
validate operator config. The zod 3 source does not compile against zod
4, so a typecheck-only override cannot fix this.

The existing tests do not prove this change, because they also passed
with the invalid one-argument `z.record`. So I parsed 45 inputs with the
same schema on zod 3.25.76 and zod 4.6.7:

| Result | Inputs | Detail |
| --- | ---: | --- |
| Identical | 23 | Includes defaults, valid config, and a `__proto__`
key |
| Same outcome, new error wording | 21 | For example, `Invalid url` is
now `Invalid URL`. `validateConfig` shows this text to operators. |
| Different outcome | 1 | `jobTtlSecondsAfterFinished: 2 ** 60` was
valid and is now rejected. The new limit is `Number.MAX_SAFE_INTEGER`. |

I did not test this against a real cluster.

The decision is to keep this change in this pull request. Since then,
paperclipai/paperclip#17364 has moved the rest of the repository to zod
4.6.x, so the Kubernetes plugin now matches it.

### Behavior change for review

`reducedMotion` under `use` is not a Playwright option. It had no effect
in 11 configs and 2 `test.use` calls, so those suites ran with
`no-preference`. The options are now under `contextOptions`, so reduced
motion now takes effect. `app-shell-design.spec.ts` asserts a real
transition, so it now asks for `no-preference` itself.

The baseline manifest has `snapshotCount: 0`, so this invalidates no
published baseline. A frozen trial reference PNG can differ.

### Findings

These are product questions. I did not change them, and I did not hide
them with casts:

1. **`PrpEvent` and its schema disagree.** The TypeScript type in
`src/protocol/replay-contract.ts` requires `normalizedSessionId`. The
`required` list in `protocol/schemas/event.schema.json` does not include
it. `validatePrpEvent` accepts events that the type forbids.
2. **`requestCheckboxConfirmation` is stricter than its runtime.** It
uses the output type, so plugin authors must pass `continuationPolicy`
and `allowDeclineReason`, although the schema gives them defaults.
`z.input` would fix this.
3. **`RetainedRunnerdMaintenanceInput.backend.kind` is a free string.**
The quarantine domain comes from `descriptor.kind`, but the release uses
`proof.backend.kind`. If they differ,
`completeRetainedNativeSessionCleanup` returns 0 and the quarantine
stays. The production caller passes `"runner"` today, so this is not a
live bug.
4. **`CodexHarnessSession.close(input?)` is optional, but the contract
requires `{ reason }`.**

These are tests that verified nothing. I corrected them, and they pass:

- `backends/native-instruction-measurement.test.ts` filtered on
`placement === "core"`, which is not a valid placement. It measured an
empty tool list. It now measures 14 tools.
- `drivers/acpx/codex-acpx-driver.test.ts` checked for `usage.updated`,
which is not an event type.
- The `hostFixture()` helper in `drivers/acpx/runtime-host.test.ts`
ignored two overrides, so
`expect(prepareSandbox).not.toHaveBeenCalled()` could not fail.
- `live/live-session.test.ts` set `agent: "pi"` before a spread that
overwrote it.
- `native-distribution-integrity.test.ts` passed an AbortSignal where
`openCommand` expects `{ signal }`.

These are gaps that this pull request does not close:

- **The root lockfile still has some old zod versions.**
paperclipai/paperclip#17364 moved the direct zod dependencies to 4.6.x.
`pnpm-lock.yaml` still resolves `zod@3.25.76`, `4.1.11`, and `4.4.3`,
which are below the patched 4.6.6.
`packages/paperclip-runner/scripts/pi-distribution/package.json` pins
`zod` to `3.25.76`, and some agent SDKs resolve `4.4.3`. Dependency
review does not flag them, because this pull request does not add them.
- **Dead GitHub coverage.** `chat-adapters-ui-providers.spec.ts`
returned early for GitHub, so four later `provider === "github"`
branches never ran. I removed them. They included the private key file
and paste match, and the reconnect flow. Nothing asserts those behaviors
in that spec now.
- **Provider tests do not run in CI.** The root `vitest.config.ts` lists
only Daytona. The other 8 providers, `bridge-template` included, are
typechecked now, but CI does not run their tests.
- **One `packages/db` test never runs.**
`scripts/clean-poisoned-claude-sessions.test.ts` is outside the
`include` of `packages/db/vitest.config.ts`.
- **`plugin-orchestration-smoke-example` does not collect.**
`@paperclipai/shared` is not linked in its `node_modules`. It passes 3
of 3 with an alias.

## Verification

Run these commands:

```sh
node scripts/typecheck-test-programs.mjs --low-memory
pnpm --filter @paperclipai/server typecheck
node scripts/typecheck-test-projects.mjs --low-memory --reuse-declarations
node --test scripts/typecheck-test-programs.test.mjs
```

Results on macOS (arm64), Node 26.12. CI uses Node 24, and its
`Typecheck + Release Registry` job also passes. At head `7d4b5e907a`,
the test programs, `tests/e2e`, and the script tests pass again with 0
errors. The times and peaks below come from the run before the two
latest merges of master:

| Check | Result |
| --- | --- |
| Test programs, `--low-memory` | Exit 0, 0 errors, 42 seconds, peak
1.78 GiB |
| Server layers, low memory | Exit 0, 0 errors, 38 seconds, peak 3.41
GiB |
| Test projects, including `tests/e2e` | Exit 0, 0 errors, 13 seconds,
peak 1.59 GiB |
| Script tests | 12 passed |
| Injected type error in each of 23 places | Each one failed its program
with TS2322 |
| Coverage check | 0 unchecked files, 10 seconds |

I did not run this in a 4 GiB container. The peaks above are `maximum
resident set size` for the largest single process.

**Runtime check of the fixes.** Types do not prove that a test still
works, so I ran the suites before the two latest merges of master:

| Suite | Result |
| --- | --- |
| Runner, full suite | 4,885 passed, 3 failed, 13 skipped |
| Sandbox providers, 10 packages | 939 passed, 12 failed, 36 skipped |
| Plugin SDK | 200 passed |
| `kv-demo-mcp-server` | 12 passed |
| Renamed UI test and its sibling | 4 passed |

All 15 failures exist without these fixes or come from the local
machine:

- **3 Cursor Cloud timeouts.** `artifact-delivery.test.ts` has 1 and
`cursor-cloud-driver.test.ts` has 2. They time out in a full local run,
and all 133 tests in those files with `codex-security-config.test.ts`
pass when run alone. They fail in the same way with those two files at
their unedited versions.
- **12 Kubernetes `file-sync.test.ts` failures.** They fail in the same
way before and after the fixes. The first failure is that
`/proc/self/fd` does not exist on macOS.

After each of the two latest merges of master, I ran only the Runner
test files that I changed:

| Merge | Result |
| --- | --- |
| `885c249cb9`, 8 files | 534 passed |
| `7d4b5e907a`, 7 files | 672 passed, 16 failed |

The 16 failures are in the two `source-reconciliation` test files. They
fail in the same way with master's unedited versions of those files. 15
of them fail with `ACPX sidecar exited at initialize`, so I think my
local build of the Rust and sidecar binaries is out of date. I did not
rebuild them to check. CI builds them from scratch, and all Runner jobs
pass in CI at `7d4b5e907a`.

**Not run:**

- `tests/e2e` and the 8 Playwright suites need a server, so most of them
have only compile checks. `playwright test --list` loads 308 tests from
the main e2e config.
- `packages/plugins/sandbox-providers/kubernetes/test/integration` needs
a cluster, so it has only compile checks.
- I did not run the full `pnpm test:run` or root `pnpm build`. Required
CI runs them.

**Reduced motion.** I ran 6 motion-sensitive Storybook specs in system
Chrome with a temporary config, once with `reduce` and once with
`no-preference`. Both runs had 45 passed and the same 5 failed. So
reduced motion did not change those results. The 5 failures do not
depend on motion. At least one comes from the browser, because system
Chrome prints `oklch(55.6% 0 0)` where the test expects `oklch(0.556 0
0)`. I did not run the other Storybook specs. The `storybook-visual`
label runs that workflow.

## Risks

- **A new lockfile to maintain.** A change to a provider `package.json`
now fails the typecheck job until someone refreshes
`scripts/typecheck-sandbox-providers/pnpm-lock.yaml`. The failure
message gives the command.
- **The job has a new install.** The step downloads provider SDKs, so it
depends on the npm registry. It uses `--frozen-lockfile` and
`--ignore-scripts`.
- **The local install replaces provider `node_modules`.** A contributor
with a standalone provider install must reinstall that provider after
running the script.
- **Reduced motion can change Storybook results.** See "Behavior change
for review". That workflow is not part of required CI.
- **Kubernetes plugin validation changed.** A release of this plugin
ships zod 4. Error wording changes, and very large integers are now
rejected. See "Production change for review".
- **Master moves fast.** Each merge of master brought new test code with
type errors, 27 so far. After this merges, the check reports those
errors in the pull request that adds them.

DottaandPaperclip d38cdf261a perf(ui): speed up Tasks and Inbox startup (#18492)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Tasks and Inbox are the main entry points for that work.
> - Earlier changes made their data reads and row counts smaller.
> - Those changes remain, but shared controls now pull in the whole
task-detail bundle.
> - A cold open can also read a remembered organization before selecting
the one in the URL.
> - This pull request separates collection code and selects the
addressed organization first.
> - It warms task code after collection paint, so the next task open
stays fast.

## Linked Issues or Issue Description

Refs #17756, #18323, #16849, #17041, #17983, #17960, #18461.

**What happened?**

Tasks and Inbox still use their optimized index reads and row budgets.
However, small shared controls and hooks were placed in the task-detail
chunk. A collection had to download that whole chunk. The HTML also
preloaded it on every route. The original production profile loaded
about 6.5 MB of decoded JavaScript before useful rows, or 1.9 MB
transferred with compression.

Company bootstrap could select a different remembered organization
before Layout selected the URL's organization. This started unnecessary
company reads. A retained multi-company browser fixture reproduced two
attention-count requests for different companies.

**Expected behavior**

Show correctly scoped, stable collection rows without waiting for
task-detail code. Keep compact reads, bounded rendering, direct task
preloading, immediate New Task input, and fast follow-on navigation.

**Steps to reproduce**

1. Use a production UI build with Coordinator enabled and two active
organizations.
2. Remember one organization, then cold-open Tasks or Mine in the other.
3. Inspect startup script and company requests before the first useful
row.

The baseline UI revision is `91fdf02e95`. This is a UI change. It has no
API, schema, migration, or authorization changes.

## What Changed

- Group the static collection dependency trees above the task-detail
group. Keep the existing startup and task grouping strategy.
- Preload task detail and its static dependency closure early on direct
task and agent-chat URLs. Keep collection aliases out of that preload.
- Fetch the immutable task chunk at low priority after a collection
paints, or on a same-origin task-link hint. After a successful immutable
response is fully read, module-preload the cached chunk so it can
compile without executing. A failed HTTP probe skips module preload.
- Prefer an addressed active organization during bootstrap. Preserve
manual selection, archived-company handling, and account-scoped company
lists.
- Preserve a task reading anchor when a programmatic scroll event
reports an unchanged offset during restore reflow. Strengthen the Back
journey to wait for a completed collection navigation.
- Add production-browser checks for delayed indexes, correct company
scope, stable row geometry, failed speculation, and early direct-task
preload. Update collection verification notes and the feature map.

## Verification

Final source: `e402ab7fc6`; baseline UI: `91fdf02e95`.

- All **234 focused unit cases** and **44 production-browser journeys**
passed on the final source: 33 task journeys and 11 collection journeys.
Coverage includes compact history, saved cards, draft persistence,
avatar continuity, failed-probe recovery, delayed data, pagination, deep
links, desktop/mobile and reading-position restoration through Back.
Desktop and mobile screenshots were inspected.
- Workspace typecheck, full production build, map checks, token gates
and diff checks passed. The default local `pnpm test:run` still stops
before executing tests because the existing chat-test line selector
reports `No test found` (1,816 skipped). This is not a passed full local
test suite. Focused tests and remote CI remain separate evidence.
- Greptile reviewed the exact final commit at **5/5**, with zero open
review threads. Final code CI passed. The complete check inventory is
**55 successful, 3 skipped, 1 neutral**. The neutral result is the
separate Paperclip Review: its agent finished without completing an
assessment, so it is not a passing review score.

Five alternating baseline/candidate pairs per scenario, Chromium
151.0.7922.34, 1440×900, 4× CPU, 50ms latency, approximately 9Mbps down
/ 1.5Mbps up. Cold cases use fresh browser contexts with normal cache
writes enabled; warm cases use the same context and normal application
query cache. Both previews use the server's immutable hashed-asset cache
policy and uncached HTML, with real local feature settings and no
request interception. All task-owned builds and suites were stopped
during timing; other host activity was uncontrolled. Readiness requires
useful rows and editable search, or the readable task thread and
editable composer, followed by two animation frames.

| Journey | Baseline median (range) | PR median (range) | Median paired
saving |
| --- | --- | --- | --- |
| Cold Tasks | 3239 ms (3189–3333) | 2545 ms (2441–2682) | +752 ms |
| Cold Inbox | 3207 ms (3203–3268) | 2679 ms (2502–3062) | +541 ms |
| Warm Inbox | 717 ms (701–917) | 760 ms (745–768) | -47 ms |
| Warm Tasks | 1150 ms (1126–1207) | 1136 ms (1119–1174) | +18 ms |
| First task click | 943 ms (932–1008) | 1007 ms (976–1098) | -74 ms |
| Back to Tasks | 584 ms (568–617) | 566 ms (559–575) | +10 ms |
| Cold direct task control | 3389 ms (3377–3402) | 3415 ms (3395–3896) |
-13 ms |

All five pairs improved for each cold collection. The signed saving is
baseline minus candidate for each pair; it is distinct from the
difference of medians. Warm navigation is broadly similar. First task
click was 74ms slower by median paired difference. Direct-task median
paired difference was 13ms slower, with one slower 3.90s candidate
sample retained in the range; this is not a claimed direct-task speedup.

Completed script transfers by collection readiness fell from about
**1.91MB to 1.14MB** (Tasks), and **1.90MB to 1.14MB** (Inbox). Task
code warms after rows paint. At the test bandwidth, the removed 0.77MB
critical transfer represents roughly 0.65s of download time; CPU and
network overlap, so their savings are not added. Unthrottled loopback
API control medians stayed about 17–18ms in both variants. All 30 cold
samples had zero browser errors.

Rejected experiments remain separate: automatic splitting produced over
200 startup requests; disabling recursive grouping slowed direct tasks;
HTTP-only warming improved collection startup but slowed first task
opens. The final correction preloads direct dependencies and compiles
successfully cached code after paint. Routing disables HTTP caching, so
intercepted runs were kept as diagnostic evidence rather than used for
warm-cache acceptance; see [Playwright's cache
behavior](https://playwright.dev/docs/api/class-page#page-route). Vite
preview's default asset `no-cache` policy was also corrected to match
the shipped server before final measurement.


## Risks

- Bundle placement affects shared consumers. Browser checks cover
collections and task navigation; the full PR checks also cover other
routes.
- Code warming still transfers the task chunk if the user stays on a
populated collection. It moves that download past first paint and does
not execute it. This is a startup latency improvement, not a claim that
all eventual bytes disappear.
- A direct click before warming finishes still loads code on demand.
Direct task and chat URLs retain early module preload.
- Local browser evidence does not establish a deployed staging speedup.
This PR does not merge or deploy itself.

## Model Used

OpenAI GPT-6 (Codex), with reasoning, tool use and local code execution.
The context-window size is not exposed in this environment.

Devin FoleyandPaperclip faf72cb1d5 fix: preserve company context across browser hot reload (#14482)
## Thinking Path

> - Paperclip uses a shared company context for browser providers and
consumers.
> - Vite can load a new consumer module while an older provider is
mounted.
> - Recreating the context disconnects that consumer from the mounted
provider.
> - The consumer then reports a missing provider even though one is in
its React ancestry.
> - This change preserves the context object across development module
refreshes.
> - Bounded global error diagnostics distinguish development bundles and
otherwise context-free promise rejections.

## Linked Issues or Issue Description

**What happened?**
A refreshed company consumer can throw `useCompany must be used within a
CompanyProvider`. A real Vite and Chromium reproduction confirms that a
retained provider and a refreshed consumer can hold different context
objects. Global promise rejections also lack the bounded document state
already attached to React boundary errors.

**Expected behavior**
A refreshed consumer should read the mounted provider. Error reports
should identify the loaded bundle mode and bounded browser state while
preserving monitoring opt-in, sign-out, and privacy behavior.

**Steps to reproduce**
Run `pnpm test:e2e:browser-context`. The isolated Vite fixture renders
the real CompanyProvider, imports a new timestamped consumer module, and
renders that consumer below the retained provider. The test fails before
the context change and passes after it. The SDK regression invokes its
real unhandled-rejection handler with an undefined reason.

## What Changed

- Keep the React context object in Vite's per-module `hot.data`. Account
values stay in React.
- Add an isolated browser regression with mocked API responses and no
live instance, discovered by the existing Chrome CI shards.
- Add document-state diagnostics to global errors while preserving
earlier boundary snapshots.
- Tag events with development or production bundle mode and the type of
an unhandled rejected value.
- Document the new test command and diagnostic fields.

## Verification

- Company context, browser context, and Sentry suites: 59 passed.
- `pnpm test:e2e:browser-context`: passed in Chromium. The original
context code fails the reproduction.
- Real SDK tests preserve DSN/sign-out behavior and omit request
context, breadcrumbs, and private DOM data.
- `pnpm check:token-gates`: passed.
- `pnpm -r typecheck`: passed.
- `pnpm build`: passed.
- Local `pnpm test:run` exited in the general-server phase: 13,819
passed, 86 skipped, 21 failures in unchanged filesystem and host-port
suites. Cache permission and long-path failures also reproduce on the
unmodified base; seven other failures involve local runtime port
ownership. This is not a full local pass.
- Full Linux CI and review passed at a0b5270662 (53 successful checks;
two conditional checks skipped). Three jobs interrupted by a runner
shutdown passed on rerun. Greptile is 5/5 with no unresolved comments.
The real browser regression also passed in the normal Chrome CI shard
(3.2 seconds).
- Code-owner approval remains required because the dedicated test
command changes `package.json`.
- Scanned the diff and PR text for credentials and private data before
pushing.

## Risks

The context cache applies only to development hot reload. It retains the
context object, not account state. Production continues to create an
ordinary React context. The diagnostic hook adds only bounded state and
type values, preserves boundary snapshots, and returns the original
event if enrichment fails. It does not suppress errors or restore raw
breadcrumbs. The global rejection diagnostics do not identify the
promise's originating operation by themselves.

## Model Used

OpenAI GPT-6 through Codex, with repository inspection, code editing,
and command execution. The runtime does not expose a more specific model
revision or context-window size.
