Nicky LeachandClaude Opus 5.5 11ac90e31f fix(build): typecheck server/src/__tests__ and fix every type error (#18739)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The server has about 1,100 test and helper files in
`server/src/__tests__`
> - `server/tsconfig.json` excludes that directory, Vitest does not
check types, and no script runs the tsconfig in that directory
> - So a test can call a function with the wrong arguments and still
pass, and no tool reports it
> - This gap hid 2,168 real type errors, and some of them hid tests that
did not test what they claim
> - This pull request fixes all of these errors and adds the directory
to the server layers from paperclipai/paperclip#18737
> - The benefit is that a type error in a server test now fails the
typecheck, with no baseline and no backlog

## Linked Issues or Issue Description

Refs paperclipai/paperclip#18737, which is merged and added the server
layers. Refs paperclipai/paperclip#18738, which is merged and checks the
test projects outside `pnpm -r`, so it is not a duplicate. Refs
paperclipai/paperclip#18137, which records that this directory has no
check.

**What happened?**

No tool checked the types of 1,074 of the 1,101 files in
`server/src/__tests__`. I searched `package.json`, the workflows, and
all tsconfig files. 27 files are in the program of another tsconfig, and
these 27 have 0 errors. 11 of the 27 are in
`helpers/maintenance/tsconfig.json`. No script ran that project when I
measured this. paperclipai/paperclip#18738 now runs it.

**Expected behavior**

The server typecheck checks these files, and a type error fails the
check.

**Steps to reproduce**

1. On the base commit, run `tsc -p server/src/__tests__/tsconfig.json
--noEmit`. It reports 6,536 errors and needs 12.3 GiB.
2. Add a type error to any file in `server/src/__tests__`.
3. Run `pnpm --filter @paperclipai/server typecheck`. It passes.

**Paperclip version or commit**

I measured the error breakdown below on commit `8dfd632452`, with
TypeScript 7.0.2. The branch now includes master up to
paperclipai/paperclip#18865.

**Deployment mode**

Not applicable. This issue applies to development and CI. No production
source file in the server changes.

### Error breakdown

Each row adds one change to the row above.

| Step | Total errors | Change | Cause |
| --- | --- | --- | --- |
| Config as committed | 6,536 | | |
| Add `src/types/*.d.ts` | 4,447 | -2,089 | Config. The Express request
types were missing. |
| Set `rootDir` to the repository root | 2,436 | -2,011 | Config. |
| Set `allowImportingTsExtensions` | 2,181 | -255 | Config. Vitest
accepts `.ts` imports. |
| Add `ES2024.Promise` to `lib` | 2,138 | -43 | Config. Node 24 has
`Promise.withResolvers`. |
| Set `allowJs` for `.mjs` imports | 2,148 | +10 | Config. It removes 8
`TS7016` errors and shows new real errors. |
| Set `declaration` to false | 2,142 | -6 | Config. Tests emit nothing.
|
| Count only files in `server/src` | 2,058 | -84 | Other packages: 53
Daytona, 29 Runner test, 2 UI. |

So 4,478 of the 6,536 errors (69%) came from config or scope, and 2,058
are real type errors in 314 files. The 29 Runner test errors are also
real, which gives 2,087 errors. Tests that master added after this
measurement had 81 more errors, so this pull request fixes 2,168 errors.

This table classifies the first 2,058 errors.

| Kind of real error | Errors |
| --- | --- |
| Wrong argument or assignment type | 1,023 |
| Stale or partial fixture objects | 525 |
| Property that the type does not have | 317 |
| Missing narrowing of null or unknown | 101 |
| Implicit any | 60 |
| Missing name or module | 16 |
| Other | 16 |

### What the type errors hid

Most errors were stale fixtures and loose mocks. These errors hid real
test problems, and this pull request fixes them:

- **A test that never ran.** `instrumentation.test.ts` required
`sdk-trace-base`, which is not installed. So 3 span tests were skipped.
They now run and pass.
- **Assertions that could not fail.**
- `issue-thread-interactions-service` used a company ID as an issue ID.
- `status-card-evaluation-work` compared `[]` with `[]` in a rollback
check.
- `slack-conversation-lifecycle` read `item.issueId`, which does not
exist.
  - `email-channels` used a permission key that does not exist.
- `heartbeat-project-env` imported `LOW_TRUST_REVIEW_PRESET`, which is
not exported. The value was undefined.
- **Postgres processes that did not stop.** 11 test files called `stop`
on the test database helper. That method does not exist, and the helper
method is `cleanup`.
- **Arguments that the service ignored.**
- `methodKey` is now `connectionMethodKey` in the Daytona, Unikraft,
1Password, and Railway tests.
- 108 calls passed `"owner-user"` to a parameter that expects an options
object.
- 9 chat wizard fixtures passed `managementContext` as `source`, so they
ran `existing_app` and not `manifest`.
  - 2 tests passed a `{ userId }` actor that the function ignores.
- Inserts into `environments` passed a `companyId` column that the table
does not have.
- **Problems in tests that master added during this work.**
- `sandbox-creation-operations` read `database.connectionString` when an
external test database was set. In that mode `database` is undefined, so
the fixture would stop with a TypeError. It now uses the external URL.
- `idle-completed-history` set a Dot operation to `dispatched`. That is
a Muse status, and the Dot type does not have it. The fixture now uses
`admitted`, which is a real in-flight Dot status.

### Possible product problems, not changed

These may be real problems in production code or types. I did not change
them, because this pull request does not change production behavior:

- `decisions-service` `service.create` does not validate the lenient
`cancel_issue_tree` input.
- `createConnection` ignores `input.connectionPurpose`.
- The `createConnection` route schema default stores `{}` for
`transportConfig`.
- `prepareManagedAiRuntime` accepted the invalid value `mode:
"connection"`.
- `createBinding` accepts invalid `projectionClass` strings outside
class 3.
- `ensureManagedProjectWorkspace` forwards an untyped `repoRef` by
spread.
- `routineVariableSchema.label` is optional, but `RoutineVariable.label`
is required.
- `ToolRunContext.projectId` may be too strict.
- `withdrawInteraction` reads `issue.status`, which its type omits.
- `issueService.list` and `reconcileNativeFinalizations` omit fields
that they return at runtime.
- `createGitHubExternalObjectProvider` handles `tokenProvider: null`,
but its type forbids this value.

## What Changed

- Fixed the 2,168 type errors. The diff changes 322 test and helper
files.
- Corrected `server/src/__tests__/tsconfig.json`. Editors and the
typecheck now read the same options and report the same errors.
- Added three `test-tree` layers to
`server/scripts/typecheck-layers.mjs`. They read the server layers as
declarations, and any error fails them. A hash of the path selects the
shard, so a new file does not move other files.
- Added `server/scripts/typecheck-stubs/daytona-sdk.d.ts`. Server tests
reach Daytona plugin source, and the root install does not have
`@daytonaio/sdk`.
- Changed two imports in `ui/src/lib/issue-execution-policy.ts` to use
`.js` extensions, because server tests import this file.
- Made `declarationsConfig` and `--declarations-only` skip the
`test-tree` layers, because these layers emit nothing. Other projects
read only the source layers. Added a test for this.
- Updated `doc/DEVELOPING.md`.

## Verification

Run these commands:

```sh
pnpm --filter @paperclipai/server typecheck
pnpm exec vitest run server/scripts/typecheck-layers.test.mjs
```

Results on macOS (arm64), Node 24, 16 cores. Each check ran after the
merge of paperclipai/paperclip#18738 unless the row says otherwise:

| Check | Commit | Result |
| --- | --- | --- |
| Server typecheck, `PAPERCLIP_TYPECHECK_LOW_MEMORY=1`, all 7 layers |
`6e45a08573` | Exit 0, 0 errors, 62 seconds, peak 3.52 GiB |
| `node scripts/typecheck-test-projects.mjs --low-memory` | `a3306bd13e`
| Exit 0, 0 errors, 42 seconds, peak 3.25 GiB |
| The same script with `--reuse-declarations` | `1b878aabc0` | Exit 0, 0
errors |
| `typecheck-layers.test.mjs` and `live-recovery-work.test.ts` |
`01db5634e4` | 90 passed. These include real compiler runs for a pass, a
type error, and an invalid tsconfig. |
| `tsconfig.declarations.json` after a full server typecheck |
`0fb1e4fb0a` | It references only `below`, `cycle`, and `above`. No
generated config names a `tsconfig.layers.json` file. |
| Owned runtime test in `idle-completed-history` | `e8f2f448ac` |
Passed, with the fix that master later replaced |
| `idle-incoming-wake`, `plugin-idle-manager`, and the changed
`chat-channels` test | `6e45a08573` | 30 passed |
| Runner `native-execution.test.ts` | `eab4dcc1f4` | 114 passed |
| The 19 server test files that changed since `eab4dcc1f4`, and
`typecheck-layers.test.mjs` | `259737b700` | 4,275 of 4,277 passed. The
2 failures are in `chat-channels` and are in the list of 7 below. |

The peak is the largest single process, from `/usr/bin/time -l`. Peaks
for the server typecheck were between 3.42 GiB and 3.56 GiB across 8
runs. Peaks for the test projects were 3.25 GiB and 3.37 GiB across 2
runs. I did not measure a cgroup.

**Runtime check of the fixes.** Types do not prove that a test still
works. So I ran all 309 changed server test files, 11,929 tests, before
the rebase onto paperclipai/paperclip#18737:

| Result | Tests | Detail |
| --- | --- | --- |
| Passed | 11,913 | Includes the 2 tests and the 54 `dot-runner` tests
that passed in a later run, as described below. |
| Failed | 7 | The same 7 tests also fail on the commit before the
fixes. |
| Skipped | 9 | These tests have their own skip conditions: `sentry` 5,
and 1 each in `bundled-plugin-registration`, `customer-success-cloud`,
`onepassword-connection`, and `workspace-runtime-https-live-exercise`. |

The 7 tests that fail with and without this change, on my machine:

- 3 tests in `chat-channels` and `email-channels` stop with `ENOENT` on
a `SKILL.md` file. The path is in the parent checkout, above the git
worktree that I used, so I expect that the worktree is the cause. I did
not prove this.
- `workspace-instance-cleanup` compares `/private/var/...` with
`/var/...`. This is a macOS symlink difference.
- 2 tests in `git-reproducible-managed-checkouts` get
`unknown_base_git_files` and expect `unpushed_managed_checkout`. I did
not find the cause.
- 1 more test in `chat-channels`, `materializes direct external-chat
finals once`, gets `undefined`. I did not find the cause.

CI is the check for these 7 tests. `ci / verify` passed on `eab4dcc1f4`.

Failures during this work:

- My fix to `agent-runtime-connector-access` changed an invalid
permission key in the setup, but not in the assertion. The runtime check
found this. I corrected the assertion, and the file passes.
- `heartbeat-plugin-environment` failed one wait in the full run. It
passed three times alone, so I think that load caused the failure. It
can fail again under load.
- `dot-runner` skipped all 54 tests in the full run because `cargo` was
not on my `PATH`. It then passed 54 of 54 with the toolchain on the
`PATH`.
- My first `lib` value removed the default DOM types, and the error
count went up by 375. I added the DOM libraries.
- My Daytona stub with bare `any` left 48 errors, because generic
helpers then inferred `unknown`. I added shapes that return promises.
- One fix to `agent-secrets-routes` used `class_3_static_lease`, and the
test failed. That class allows only specific paths. I reverted to
`unclassified`.
- `ci / General tests (server (8/12))` failed on `259737b700` because of
the flaky port in `idle-completed-history`. paperclipai/paperclip#18853
fixed this test on master, so this pull request keeps that fix.

**Audit of the diff.** I counted these patterns in added and removed
lines, to find fixes that only hide an error:

| Pattern | Added | Removed |
| --- | --- | --- |
| `@ts-ignore` | 0 | 0 |
| `@ts-expect-error` | 0 | 1 |
| `.skip` | 0 | 0 |
| `as any` | 9 | 9 |
| `: any` | 11 | 2 |
| `as never` | 8 | 2 |
| `as unknown as` | 35 | 4 |
| `Promise<unknown>` | 16 | 5 |
| `expect(` | 128 | 113 |

No hunk removes more `expect(` calls than it adds. Three removals of
test content were intentional, and I checked each one:

- `muse-control` removed `signalToken`. Line 1012 already asserts that
it is absent.
- `merged-pr-confirmation-sweep` removed legacy aliases. Other tests
cover them.
- `heartbeat-workspace-branch-containment` removed a `finalize` branch
that no test row can reach.

Some partial fixtures stay unchecked through `as unknown as` and
`Promise<unknown>`, mostly in `issue-agent-mutation-ownership-routes`
and `issue-comment-reopen-routes`.

**Accuracy of the check.** One program over the tree and the three
shards reported the same errors at the same positions. Memory, as the
peak of the largest process on one thread, was 3.93 GiB for one program
and 2.43 GiB for the largest shard. I measured these two values before
the fixes.

Not run or not proven:

- I did not run the full `pnpm test:run`, or a root `pnpm build`. I
expect CI to run the full suites.
- I did not run the 4 GiB container check, or the full
`scripts/typecheck-low-memory.mjs`. The peaks above come from macOS, so
they are not a Linux cgroup measurement.
- I did not run the UI typecheck after the merges.
- `workspace-runtime-https-live-exercise` is skipped, so its `cleanup`
fix did not run.

## Risks

- **A large diff in test files.** 328 files change. A pull request that
edits the same tests can get merge conflicts. New tests on master can
also add type errors before this merges. Any such error fails this check
and needs a fix here.
- **A higher cost for changes to source types.** A change to a type can
add errors in test files that the author did not touch. The author must
then fix them. This is the purpose of the check, but it is new work.
- **Changed test behavior.** Some tests now run paths that they did not
run before, such as the 9 chat wizard fixtures and the 3 span tests.
They pass here, but they can be more sensitive to timing or to the
environment.
- **The Daytona stub can go stale.** The stub is written by hand. If the
plugin uses a new SDK member, the typecheck reports an error until
someone updates the stub.
- **The release path.** `release-verify.yml` and `scripts/release.sh`
run `pnpm -r typecheck`, so they now run this check.
- **The tsconfig change.** The test transform reads
`server/src/__tests__/tsconfig.json`. The options that I changed are for
type checks, and the runs above passed.
- **A gap that remains.** Tsconfigs in `packages/paperclip-runner` and
in most sandbox provider plugins exclude `*.test.ts`. This check does
not read most of those test files, so they can still drift. That work is
separate from this pull request.

DottaandPaperclip c0550e7010 fix(server): preserve sessions and defer busy overlap recovery (#18552)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - A web server replacement must preserve remote execution and later
task continuation.
> - The active-run handoff now survives deletion of the departing server
home.
> - The next admission still compared disposable instruction and skill
paths as configuration.
> - A native receipt could also settle without the old adapter returning
its terminal metadata.
> - A replacement can also collide with a run row locked by the serving
controller.
> - This change preserves durable session identity and terminal
evidence, and defers locked recovery work so overlap can reach
readiness.

## Linked Issues or Issue Description

Refs #18543, #18366, #9977, #18118.

**What happened?**

A real Codex/Daytona journey replaced both control-plane servers and
deleted their homes. Reads, saves, saved files and active execution
passed. A later useful answer used a new provider session. All four run
records lacked the native terminal contract. The whole qualification
therefore failed. A later attempt also exposed startup failure: the
replacement waited for a row lock held by the serving controller and
aborted on its one-second lock timeout.

**Expected behavior**

An unchanged managed instruction entry and immutable skill version
retain the session across server cache relocation. Actual content and
configuration changes still reset it. A committed native receipt retains
its terminal contract even when the originating adapter never returns. A
busy recovery row defers through the existing scheduler while the
replacement reaches readiness.

**Steps to reproduce**

Run the `rolling-web-deployment.runner-codex.daytona.recover-controller`
Product E2E cell with separate controller homes and shared
PostgreSQL/S3. The focused regressions reproduce the failures without a
model call.

## What Changed

- Read the managed instruction entry digest from the company-scoped
durable file head. Do not restore or read the cache for this check.
- Omit disposable instruction paths only when that durable authority
exists. Fingerprint selected immutable skill versions in both runtime
skill inputs.
- Preserve the existing local and external instruction path checks, and
unversioned skill identity.
- Publish the accepted native terminal contract in the same transaction
as the canonical result receipt.
- Skip locked recovery rows and schedule the same run for retry. Avoid
an audit write that would block on the same row. No ownership is
transferred while busy.
- Keep replacement readiness independent of an in-progress skill
selection; migration and cache eviction still require exact pins.
Missing durable skill versions still refuse startup.
- Project only the instruction digest in SQL instead of loading the
entire agent-file manifest per admission.
- Add real PostgreSQL lock contention tests for the issue, run and
coordinator, including the heartbeat startup caller and later claim.
- Limit native test teardown to its owned database on a shared test
host. The old behavior also fails on clean master.
- Add cache-loss, scope, changed-content, changed-version and
finalization regressions. Update the deployment qualification record.

## Verification

- Both focused regressions failed before the source changes.
- All 249 tests pass across `heartbeat-workspace-session`,
`agent-file-durability`, and `paperclip-control-plane-port`.
- Server typecheck and exact-revision build pass.
- Assembled admission ran 59 passing cases but failed during
native-suite teardown. The teardown failure reproduced on clean master.
All 16 native resumption cases and teardown pass after the
database-scope fix.
- All three row-lock regressions fail with the pre-fix lock timeout and
pass with deferred recovery. The full recovery suite passes 74 cases,
including the startup caller; eight Docker-specific cases were not
enabled.
- The real attempt at `d2165dec5d` failed when B aborted on the run
lock. Its credential and bucket were removed; all three provider
sandboxes were independently confirmed absent. The next real attempt at
`aae8a53d01` failed a different readiness gate while a run was preparing
skill pins. That race now has a failing-before regression; all 33
readiness, durable-file and managed-skill tests pass after the fix. Its
owned resources are cleaned. The `a15a12651c` live attempt passed both
web replacements: 765 reads, 78 saves and 78 verified saves with zero
HTTP probe failures. The first three turns preserved the provider
session and native terminal contract. The fourth continuation failed
because a safely suspended remote Runner was treated as live/idle; that
distinct recovery gap is being handled in a follow-up. All three owned
sandboxes were independently confirmed absent. No claim of full Railway
qualification yet.

## Risks

- The new fingerprint shape may reset a session once when upgrading from
older fingerprint metadata. It is stable across subsequent cache
replacements.
- A versioned skill is identified by its immutable selected version;
materialization and admission still enforce availability. Unversioned
skills retain their existing path boundary.
- A native terminal describes the accepted execution result. Workspace
and issue settlement remain separate authorities.
- This does not yet prove the ten-deploy staging campaign, natural
database autosuspension or the production canary.

## Model Used

OpenAI GPT-6 Codex, with reasoning, repository editing, shell execution
and live integration-test tools. The exact runtime model variant and
context-window size are not exposed in this session.

DottaandPaperclip 006d5691a6 feat(server): support volume-free web server handoff (#18518)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Its web server also owns controller admission and user commands.
> - A rolling deployment starts a replacement before the old server
exits.
> - Shared database state alone does not preserve local agent files,
browser chunks, or in-process commands.
> - This pull request adds an opt-in ephemeral server contract and a
local overlap test.
> - The benefit is a web server that can relinquish traffic and local
files without losing acknowledged work.

## Linked Issues or Issue Description

Refs #18403, #18327, #18335, #18341.

**Current behavior**

The control-plane web server still has local agent-file authority and
local command targets. A new container can miss saved bytes or send a
command to the wrong process. An existing browser tab also needs chunks
from its original build.

**Proposed behavior**

Eligible servers share only PostgreSQL, object storage and stable
secrets. A replacement waits for readiness. The old server drains
admitted requests, keeps owner commands available through handoff, and
releases controller leases. Explicit maintenance adopts existing files
before the volume is removed.

**Reason and benefit**

This is the application prerequisite for rolling app-only deployments.
Schema migrations and permanent multi-replica operation are outside this
change.

## What Changed

- Store agent-file manifests in PostgreSQL and immutable bytes in S3.
Treat local roots as disposable projections. Preserve existing
permission checks and edit conflicts.
- Add an explicit migration, eligibility and object-retention command to
the production runtime bundle.
- Add `/api/ready`, admitted-request drain, browser restart signaling
and retained immutable UI chunks.
- Carry transaction-aware work hints across controllers during handoff
and active execution. Keep listeners closed when idle.
- Deliver durable Stop and runtime responses to the execution owner.
Recheck request lifecycle and access before response dispatch.
- Reject local-only configuration in ephemeral mode. Keep the feature
disabled for existing installations by default.
- Add an isolated PostgreSQL/S3/proxy/browser deployment harness with
independent server homes and retained failure evidence.

## Verification

- All CI checks pass on `ce17b95019d3cf1cabd357d19b6d37f96782cc5c`:
workspace typecheck, build, Runner checks, server/general tests and
browser shards. Greptile reviewed the runtime changes at 5/5 with all
findings resolved; the final commit updates maps and the plan.
- Local targeted checks passed: coordinator 27; Stop/recovery 33;
PostgreSQL command delivery 6; route/workspace regressions 8; bootstrap
Stop 1; restart recovery 75. PostgreSQL command tests simulate the
provider edge.
- Local browser proof passed 91 reads and 19 saves; reconnect took
1,013ms. The tab opened Audit from S3 after deletion of A's whole
home/build. This uses compiled workspace code and local-trusted auth,
not released containers or live agents.
- Local workspace typecheck/build passed; current server and runtime
bundle passed. The earlier broad local suite was stopped after three
hours and is not a passing receipt. Its retained failures and isolated
reruns are documented in the plan.
- Stacked #18526 adds stricter graceful-exit proof, an unready
replacement control, live Runner qualification and a Stop handoff
correction. Hosted enablement remains gated on those results and Cloud
#1096. No hosted stack has been enabled.

## Risks

- Apply migration 0422 before enabling the feature. Existing data must
pass each owner's migration and eligibility checks. Do not discard a
volume based on a single migration page.
- Durable manifests remain authoritative after the opt-in is disabled.
Rolling back to a binary that ignores them is unsupported.
- Cold directory restoration and complete shutdown timing still need
qualification before enabling a hosted stack.
- Retained UI assets must cover the supported browser and rollback
window. Cleanup is explicit; no new idle maintenance polling is
introduced.
- This change does not claim production zero downtime or authorize a
fleet-wide enablement.
