danusha2345andClaude Fable 5.1 2521b49a9a fix(resolution): fuzzy reachability rejects a unique guess, never manufactures one
A function nested inside another function is only callable from inside its
container (#1230). matchByExactName already declined such candidates; the
fuzzy fallback did not, so a builtin method call (`res.text()`) whose only
same-named project symbol was some file's closure resolved onto that
closure at 0.5 (#1708).

and on vitejs/vite@8492422 that traded 12 correct removals for 59 wrong
additions: the repo has a dozen `resolve` definitions, most nested, so the
filter left exactly one reachable `resolve` method and the strategy
committed every `import { resolve } from 'node:path'` call in the
playground configs to it. Filtering a crowd down to one survivor is not
evidence the survivor was ever the target.

So the check sits on the ONE candidate matchFuzzy would commit to: a
unique candidate the call cannot reach is declined; a crowd stays a crowd.
Same tree, measured against this branch's own base b9ca4b7: 12 edges lost
(all fuzzy, all onto nested functions — the same 12 #1709 removes), 0
gained, fuzzy 13 -> 1, every other resolvedBy row at zero.

The two-file fixture is #1709's, credited in the previous commit; four
direct tests pin the shape: a lone unreachable closure declines, the same
closure resolves from inside its container, closure + method is ambiguous
and declines (the candidate-set filter fails exactly this one), a lone
reachable method resolves as before.
