## What
`full-suite.yml` shard 1 on main fails with **zero test failures** — it
dies on a resolution error:
```
Failed to resolve import "@fusion/core/task-delete-attribution" from "packages/dashboard/app/api/client.ts"
```
**Root cause.** Vite string aliases match by **PREFIX**. So `find:
"@fusion/core"` → `core/src/index.ts` rewrites
`@fusion/core/task-delete-attribution` into
`core/src/index.ts/task-delete-attribution`, which cannot resolve. The
narrower subpath alias has to come *first*.
The module exists and *is* correctly declared in
`packages/core/package.json` exports — this is purely a test-config
trap, and `packages/dashboard/vitest.config.ts` already documents it in
a comment. Six configs alias `@fusion/dashboard` (whose
`app/api/client.ts` imports that browser-safe leaf) while lacking the
narrower alias, so they inherited the trap. This carries the same
one-line pattern to all six.
## Measured
`dependency-graph` — the project actually red on main:
| | Test files | Tests collected |
|---|---|---|
| before | 3 failed \| 17 passed | 147 |
| after | **20 passed** | **180** |
**33 tests were never collected** — neither passing nor reported as
failing. That is the part worth flagging: an unresolved import removes
tests from the run silently, and the shard's own summary printed no
`Tests N failed` line at all, which is why this red looked like
infrastructure noise rather than a real defect.
No regressions: `reports` 110, `cli-printing-press` 41,
`compound-engineering` 317, **gate 726** — all green. `pnpm lint` clean.
`@fusion/desktop` is `1 failed | 264 passed` **both before and after**;
verified pre-existing on clean `origin/main` by reverting just that one
config and re-running. Cause is `@fusion-plugin-examples/roadmap` entry
resolution, unrelated — **flagged, not fixed.**
## Deliberately not changed
Engine's *second* `@fusion/core` alias (the `.gate-bundle/core.mjs`
entry) is untouched: that lane bundles core on purpose, and pointing it
at source would defeat the isolation the gate bundle exists to provide.
## Full-suite triage this came out of (for whoever owns the rest)
Reading the four red shards of the last completed run on main
(`30523568756`):
| Shard | Real cause | Owner |
|---|---|---|
| 1/4 | **this PR** — resolution error, 0 test failures | — |
| 2/4 | 23 failed: `store-wedge-resolution.pg`,
`central-archive-secrets`, `task-delete-caller-attribution`,
`task-delete-nonblocking-cleanup` | #2669 / #2675 cover the first two |
| 3/4 | **watchdog SIGKILL** mid-`@fusion/engine [1/2]` — no test
failures, no summary | unowned |
| 4/4 | 17 failed, all in `@runfusion/fusion` CLI (`project.test.ts` 8,
`task.test.ts` 5, `extension.test.ts` 2, +2) | unowned |
Two of the four shard reds contain **no failing test at all**, so
"main's full-suite failure count" cannot be read off the shard
conclusions — it has to be read off `Tests N failed` summary lines, and
shards 1 and 3 emit none.
