The last of my five batch-core findings, resolved by **not** changing
code. Recording why, because "leave it" is the kind of decision that
rots into "nobody looked".
## What was wrong with the entry
It read `TEMPORARY: core-owned; reported on #2783`. That PR merged
without picking it up, so the entry implied an owner who was going to
act, and none exists. A stale exemption misreports what the project
tolerates — exactly the rot the staleness checks exist to prevent, and
one they cannot catch: the site is genuinely still unsupplied, so
nothing fires.
## Evidence, gathered rather than assumed
- **Zero callers anywhere.** The three dashboard call sites (`Lane`,
`Board`, `ListView`) bind to a **different function of the same name**
in `app/components/taskSorting.ts`. Only its own tests pass the flags.
- **Not reachable externally.** `@fusion/core` is private;
`@runfusion/fusion` declares no `exports` map and re-exports nothing
from core wholesale; it is absent from `plugin-sdk`.
So there is no production behaviour to be wrong, and no supplier to wire
it from.
## Why I did not "fix" it
This check's usual remedy is *wire a supplier, or delete the parameter
and leave the literal counted*. Neither is right here:
- **Deleting the parameter** trades a dormant-but-correct implementation
for a dormant legacy-only one. The parameter is optional and harmless;
the only thing it costs is that the census once counted it as a
conversion when it changed nothing — and that is now recorded rather
than hidden.
- **Deleting the function** discards a well-documented ordering (the
note enumerates three real renamed-board defects) that someone may
plausibly wire later.
Both are churn with no product effect, in a package I do not own.
The actual resolution is **consolidating the duplicate with the
dashboard twin** — that name collision has already cost real time twice
in this lane, including one "fix" `tsc` rejected and one bad cross-batch
report. But that is a refactor with a design question attached, and it
needs an owner rather than a seam-gate cleanup smuggling it in.
