The idx832/idx853 fork-harness helpers are used only in the POSIX (#else) branch of their tests; on Windows (SKIP_PLATFORM) they are unused → -Werror,-Wunused-function on the CLANG64 leg. Guard the definitions to match their call sites. Signed-off-by: Martin Vogel <martin.vogel.tech@gmail.com>

* resolve_store() opens <cache>/<passed>.db and then requires the internal
|
||
* `projects.name` row to equal the passed name; list_projects /
|
||
* collect_db_project_names derive the advertised name from the .db FILENAME.
|
||
* When a db's filename != its internal name (a legacy '.'-vs-'-' username
|
||
* twin, or a copied/renamed file) it shows up in list_projects under the
|
||
* filename, but every query returns "project not found" — node rows are
|
||
* tagged with the INTERNAL name, so neither the filename nor the resolve
|
||
* path lines up. The fix makes list + resolve both key on the INTERNAL name.
|
||
*
|
||
* Reproduce-first fixture in an isolated CBM_CACHE_DIR:
|
||
* - alpha704.db : filename == internal name "alpha704" (control / fast path)

* beta704.db then renamed → filename != internal name)

* - ghost704.db : 0-byte file (ghost / unresolvable)

* RED on buggy code / GREEN on the fix:
|

* A. list_projects advertises "beta704" (internal), NOT "gamma704" (filename),

* and NOT "ghost704" (0-byte filtered).
|
||
* B. search_graph(project="beta704") resolves via the cache-dir scan and
|
||
* returns the node — not the "project not found" error.
|

* C. control project "alpha704" still resolves on the fast path.
|

* D. the 0-byte ghost is not resolvable.
