What
The code that reads Linux user-namespace ID mappings was split into a pure parser over the file text, which validates all three columns and returns the inner start, host start and count for each range instead of resolving a single fallback ID itself.
Details
Callers can now see where inner IDs land on the host, which the old reader discarded.
Evidence
t.push({ innerStart: o, hostStart: s, count: u });
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
