What's Wrong?

When the working directory path contains underscores (e.g., D:\Desktop\workspace\xx_xx_xx), Claude Code encodes the path into the ~/.claude/projects/ folder name by converting underscores to hyphens (result: D--Desktop-xx-xx-xx.

The session file exists on disk and is valid, but claude --resume interactive picker does not list it.

Workaround: claude -r <session-id> works correctly.

Now I'm using claude --resume with the sessionId command to continue my work, but I need to go into the folder to get the session ID, which is very inconvenient.

What Should Happen?

Session appears in the picker regardless of underscores in path.

This is identity-matching fragility at the resume-project boundary.

If the --resume picker does not show a session when the project path contains underscores, then session discovery is depending on a path-handling assumption that treats a normal filesystem character as a lookup hazard.

Why it matters:

underscores are ordinary path characters, so users should not have to sanitize project names just to preserve resumability
when valid sessions disappear from the picker based on path shape, users experience the problem as nondeterministic continuity loss
resume/discovery surfaces need canonical project identity, not brittle string heuristics that collapse on common characters

I would want clarity on:

whether underscores break indexing, serialization, path normalization, fuzzy matching, or UI filtering in the picker path
whether the session is stored correctly but omitted from discovery, or whether the bad path handling corrupts identity earlier in the lifecycle
whether resume matching can be based on canonical path identity / session id first, with display-friendly path text as a separate concern

Continuity features need robust identity semantics. If a normal underscore in the project path can hide a resumable session, the resume boundary is still too fragile for everyday workflows.
