Summary

  • Delete low-signal unit tests across the monorepo: config/registry restatements, mock-call choreography, per-route copies of route-builder behavior, schema accept/reject checks, render/class/query-key tests, tests of mocks and factories, and near-duplicate variants. Kept: security denials, billing math, executor semantics, real parsers, cross-process wire contracts, and demonstrated regressions
  • apps/sim: 4,027 → 3,271 test files, 60,643 → 34,286 tests. Repo-wide: ~438k lines of tests removed
  • Remove production exports whose only callers were deleted tests (validateStringParam, validateRequiredFields, resubscribe, resolveSelectExportValue, getSlackV2ToolAccess, unused provider/model helpers, USAGE_PROVIDER_ICON_IDS)
  • Remove ~130 orphaned @sim/testing exports (unused assertions, builders, factories, mock helpers, setup/)
  • Consolidate the real-database layer: *.postgres.test.ts → *.integration.ts, one TEST_DATABASE_URL/TEST_REDIS_URL contract enforced by packages/db/testing/test-infrastructure.ts, CI discovers suites by glob instead of a hand-maintained file list, and every integration run uploads a JSON report. *.live.test.ts holds opt-in provider/sandbox suites (never in CI); 7 integration suites that already failed on a fresh DB are quarantined explicitly in apps/sim/vitest.config.ts
  • Upgrade Vitest 4.1 → 5.0.1 (5.0.2 is inside the minimumReleaseAge window); publish workflows run tests on Node 22 and keep a Node 20 bundle smoke
  • Drop the 3-way apps/sim test sharding — the suite runs in the Lint and Test job again
  • Drop ~2,960 redundant @vitest-environment node docblocks (node is the default) and ~2,260 vi.clearAllMocks() in beforeEach (Vitest 5 clears mocks before every test)
  • Add testing rules to AGENTS.md/CLAUDE.md: never write unit tests after the code, prefer E2E tests that end with a verifiable artifact, write failure modes down first when testing in isolation
  • Add a test-audit skill (authoring gate, junk patterns, retention bar, audit/campaign workflow), rewrite .claude/rules/sim-testing.md around test layers and naming, and gate new tests in /ship and /cleanup

Type of Change

  • Other: test cleanup, tooling, and docs

Testing

  • bun run test (every workspace + scripts + setup): all green except 2 pre-existing background/knowledge-processing.test.ts cases that fail only when the checkout path contains /private
  • Integration layer run against local Docker Postgres 17/16 + Redis in both push and migrate provisioning: every file that ran in CI before still passes; SCIM HTTP e2e 17/17
  • bunx turbo run type-check, bun run lint, bun run check:audits (49), docs-manifest:check, block registry, check:migrations all pass

Greptile will likely refuse this PR for file count; the diff is almost entirely test deletions.

…once

Round 3 review left 7 threads. Five were the same mistake: a guard added at
one read site of a value while the other read sites kept the unguarded one.
Each fix below is one derived value used everywhere, or a deleted duplicate
path, rather than another guard at another call site.

Lock-order deadlock (reported independently by both reviewers). `lineage.ts`
already declared `fork-lineage` the coarsest fork lock, but ranked only the
three advisory locks and said nothing about `lockForkRevision`, which takes
FOR UPDATE on `workspace`. `createFork` took it first, so it held that row
while waiting for `fork-lineage`, while `unlinkForkEdge` held `fork-lineage`
and waited to UPDATE the same row. Hoist the lineage lock above it, and
replace the partial contract with a rank table covering every lock in the
module. All six fork transactions now acquire in ascending rank.

Stale workspace rows in the synced-workflows list. `useWorkflows` and
`useFolders` both set `placeholderData: keepPreviousData`, so a workspace
switch served the previous workspace's rows with `isLoading: false` and a
click posted workspace A's ids against B. Gate on `isPending ||
isPlaceholderData`, matching `custom-tools.tsx`.

Fork modal submitted a value the switch showed as off. `copyUnsyncedWorkflows`
had two readings and submit used the raw one. Derive it once from the request
plus the limit, and read that at all four sites.

Audit entries named workspaces by id. Return the name from the UPDATE and
project `resourceName` from it, so a lineage-wide change no longer reads as
one named workspace and N opaque identifiers.

Also: give `setForkSyncDefault`'s multi-row UPDATE a deterministic row-lock
order, delete the non-barrel re-export left behind when the workflow limit
moved to `limits.ts`, and correct a TSDoc invariant that claimed the
`fork-target` lock for both callers when only one holds it.

Tests, per the repo's test-audit gate: add one `*.integration.ts` that races
the two real lock sequences against real Postgres and asserts the pre-fix
order deadlocks while the shipped order does not, so the check cannot pass
vacuously. Drop the re-added contract-schema test (an identical file was
pruned as low-signal in #8295), fold the fork-sync inheritance assertion into
its sibling, and reduce the synced-workflows test to the pure tree builder
whose checkbox stub no longer implements the polarity it asserts.

* feat(forks): opt-in fork sync for new workflows

Workspace forks gain a lineage-wide policy for whether a NEWLY created
workflow joins fork sync. Today a workflow joins the moment it is
deployed, so deploying something experimental in a parent pushes it into
every fork on the next sync with no step where anyone chose that.

Opt-out remains the default, so no existing or new workspace changes
behaviour until someone flips the toggle.

The policy lives on workspace.fork_sync_new_workflows_excluded (default
false, the historical behaviour); workflow.fork_sync_excluded is
untouched including its default. It is uniform across a fork lineage:
settable from any member, fanning out to every ancestor and descendant
under an advisory lock keyed on the lineage root, which fork creation and
unlink also take. It is forward-only - flipping it never rewrites an
existing workflow's sync state - and each changed member records its own
audit entry naming where the change was issued from.

Genuinely new workflows (create, duplicate, admin/superuser import, a
fork's starter) take the workspace policy. A copy (fork creation,
promote-create) inherits the SOURCE workflow's flag, because it is the
same logical workflow in another workspace; without that an opted-in
workflow would copy into a fork already excluded and never sync again.

The fork modal gains "Copy unsynced workflows" (off by default, shown
only when the source has unsynced deployed workflows, disabled when the
combined set would exceed the fork ceiling) so forking an opt-in
workspace cannot silently produce an empty fork.

The settings section becomes "Synced workflows" with the polarity
flipped - checked means the workflow syncs - above a "Sync new workflows
by default" toggle row that states its lineage-wide reach. The wire field
stays forkSyncExcluded, so the tree owns the single inversion.

* fix(forks): break the fork lock cycle and derive review-round values once

Round 3 review left 7 threads. Five were the same mistake: a guard added at
one read site of a value while the other read sites kept the unguarded one.
Each fix below is one derived value used everywhere, or a deleted duplicate
path, rather than another guard at another call site.

* test(forks): drive the lock-order suite through the production helpers

cubic's round-4 finding on the new integration suite was right: it mirrored
the lock SQL as string constants instead of executing production's, so a
`createFork` regression to the pre-fix order would have left it green.

Closed on both halves.

The fixture now calls the real `setForkLockTimeout`, `acquireForkLineageLock`
and `lockForkRevision`, against the tables the last of those actually locks,
so a change to the advisory-lock key or to the revision lock's coverage is
carried into the test rather than silently diverging from a copy. A third
check pins why the pair conflicts at all: the revision lock really does hold
the `workspace` row, which is the edge of the cycle.

The order inside `createFork` is asserted where it lives, in
`create-fork.test.ts`, on invocation order through the admission path. Order
is the entire contract here, which is the case the retention bar keeps call
ordering for.

Verified red for the right reason: reordering the two acquisitions in
`create-fork.ts` fails the new unit assertion, and the integration suite's
negative control still fails in ~1.03s with the server reporting
`deadlock detected` rather than a lock timeout.

* test(forks): scope the lock-order barrier to the unlink backend

cubic was right that counting any Lock waiter on the database could let an
unrelated session release the barrier before the unlink had blocked, leaving
the pre-fix negative control to run with its cycle still open. A weak negative
control is the failure mode this suite exists to avoid.

The unlink transaction now publishes its own backend pid before it can block,
and the barrier waits on exactly that pid. If it never blocks the race did not
set up, so it throws rather than quietly proceeding and reporting a pass.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* test(forks): settle every lock-order barrier on the failure path

Both reviewers independently caught the same real defect: a session that died
before resolving its barrier left `raceForkAgainstUnlink` awaiting a deferred
that would never settle, so a clean database error surfaced as a 30-second
vitest timeout. That hides exactly the diagnostics a concurrency test exists
to provide.

Every barrier is now settled on the failure path as well as the happy one.
The fork session releases `forkHoldsFirstLock` in a `finally`, the unlink
session reports a `null` backend when it dies before `pg_backend_pid()`
returns, and the barrier is skipped outright once a session has already
failed, so the session's own error is what the test reports. Releasing the
sessions and draining them moved into a `finally` too, along with closing
both connections, so a throw inside the barrier cannot strand the fork
transaction on `unlinkMayFinish`.

Verified by simulating the failure they described - a fork session that
throws before taking its first lock. It now fails in 1s with
"simulated early connection failure" instead of timing out at 30s.

* test(forks): drop call-count assertions from the sync-default suite

CLAUDE.md forbids tests that assert a mock was called. Three assertions in
this suite were exactly that shape - `mock.calls).toHaveLength(0)` on the
audit and analytics mocks - and they proved only what the mock itself
decided, not anything about the use case.

The no-op case now asserts the result instead: `projectAudit` maps over
`changedWorkspaces` and `afterSuccess` returns early when it is empty, so an
empty result IS "no audit, no analytics", pinned to the value the fan-out
actually reads. The admission case keeps its rejection assertion, which is
the real guarantee: admission runs before the transaction opens.

What stays reads the CONTENT of the entries filed - each one carried by its
own workspace id and name - which is a fan-out invariant type-check cannot
see and the reason this suite exists. Confirmed it still goes red on the
pre-fix code: reverting the audit-name guard fails with
"expected 'root-ws' to be 'Name of root-ws'".

* revert(forks): drop the "Copy unsynced workflows" fork override

Unchecking a workflow meant "keep it out of forking entirely", and the docs
said so: never sent, never received, never copied into a new fork. The
override made the last of those three conditional on a modal toggle. Sync
participation was never at risk - copies inherited the source's flag, so an
overridden copy landed unsynced and could not sync back - but "never copied
into a new fork" stopped being unconditional, and that is the guarantee
someone is relying on when they uncheck a workflow.

It also conflated two different states. "Unsynced" covers both "I deliberately
excluded this" and "this was never checked because the lineage default is
off", and the override copied both. The first case is the one the guarantee
exists for.

This restores the single predicate: `forkSyncExcluded` workflows are invisible
to fork creation, the diff preview, promote in both directions, and the
mapping scan, with no caller able to lift it. Removed the toggle and its
section, `copyUnsyncedWorkflows` from the request contract,
`includeSyncExcluded` from `listDeployedWorkflows` and
`loadSourceDeployedStates`, the `unsyncedDeployedWorkflowCount` field, and the
split count query, which goes back to one count carrying the exclusion
predicate.

`lib/limits.ts` goes too. It existed only so a client component could read
`MAX_FORK_DEPLOYED_WORKFLOWS` without pulling the database client into the
browser bundle, and the override's toggle was the only client reader. The
constant returns to `copy/deploy-bridge.ts`, where it is enforced.

Unaffected, and still the point of the feature: the lineage-wide
new-workflow default, its forward-only write, and the rule that a genuinely
new workflow takes the workspace policy while a copy inherits its source.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* refactor(forks): stop projecting a column the source query already pins

`listDeployedWorkflows` filters on `fork_sync_excluded = false` and then
selected the same column, so every row it returned carried `false` by
construction - `SELECT x ... WHERE x = false`. The field only ever varied while
`includeSyncExcluded` could make that predicate drop out, which the previous
commit removed, so it is scaffolding from the reverted override rather than
anything load-bearing.

Keeping it would not have been defensive either. If someone widens that
predicate they have to revisit the projection anyway, and a constant field
hides the coupling between the two instead of enforcing it.

Dropped from the query and from `DeployedWorkflowSummary`. The two write sites
now state the invariant they actually mean: a copy is not a new workflow, so it
is written synced and never takes the target workspace's new-workflow default -
which in an opt-out lineage would land a deliberately synced workflow unsynced
on the other side. That explicit write is kept precisely because it is a
semantic claim, not a read of something the query had already decided.

Untouched: the target-side read in `promote-plan.ts`, which queries target
workflows with no exclusion filter and genuinely varies. That is what keeps a
promote from overwriting a target the user unchecked.

Dropped the copy test for an unsynced source, an input no caller can now
produce, and renamed its sibling to the property that still holds.

* test(knowledge): give the member-tombstone budget test its own timeout

`finishes a pass within its page budget` times out against the shared 30s
default on a loaded CI runner. It is a load flake, not a regression: the same
commit went green on the `push` integration job and timed out on `migrate`,
and it runs in ~4s locally.

The cost is real work, not a hang. The test seeds
`MEMBER_TOMBSTONE_RECONCILE_PAGES_PER_RUN * 500 + 500` documents specifically
so one pass cannot finish inside a single run's budget, then observes and
re-lists all of it. That volume is the assertion, so trimming it to fit the
default would stop proving the multi-run path. Given its own 120s budget
instead, matching the per-test timeouts already used elsewhere in this
directory, with a comment recording why.

Unrelated to this branch's fork-sync work - the file is byte-identical to
staging and arrived with the merge - but it was failing this PR's CI, and a
flake left alone becomes one everybody learns to ignore.

* refactor(forks): render the fork-sync default with ChipSwitch

CLAUDE.md makes the chip family the canonical control chrome, and `ChipSwitch`
is what the equivalent settings row already uses (`inbox-enable-toggle.tsx`).

Two knock-on details, both forced by the control rather than chosen.
`ChipSwitch` is a Radix radio group over a string, so the boolean inversion now
runs through named values instead of `!`: `exclude` and `sync` map onto the
stored `forkSyncNewWorkflowsExcluded`. And it takes no `id`, so the `Label`
drops its `htmlFor` and the group carries its own `aria-label` - the same
pairing `inbox-enable-toggle.tsx` uses.

It also reads better here. This row's "off" means new workflows stop syncing
across the whole lineage, which a thumb position leaves the reader to infer
from the label; naming both outcomes puts it on screen.

No behavior change beyond the control: the same mutation, the same error toast,
the same placeholder-data gate.
