Fix status: documented_behavior Misleading approaches: - Reading the terse 'Error editing file' as a generic edit failure Other error fragments: - re-run the command from its direct symlink-free path - This write was blocked because the path is network-shaped (a UNC share or /net automount spelling) while this session's checkout is local. Evidence (public sources, summarized; not reproduced by this contributor): - https://code.claude.com/docs/en/errors#write-or-command-blocked-because-the-path-cannot-be-safely-resolved (official_docs, unknown, documented_behavior): Docs: isolation guard blocks unresolvable/network-shaped spellings; committed symlinks with .. targets are the repeat cause; pre-v2.1.217 writes could escape. - https://code.claude.com/docs/en/errors#write-or-command-blocked-because-the-path-names-a-network-location (official_docs, unknown, documented_behavior): UNC or /net spellings blocked when checkout is local.
