Claude Code encodes underscores as hyphens when building the project directory name under ~/.claude/projects, but encodeComponentForMatch only normalized whitespace. Any path component containing an underscore could therefore never match a readdirSync entry, so resolution stopped at the first such level and the fallback used the entire unresolved tail as the workspace name. A user whose home directory is /home/my_name saw every Claude workspace labeled "my-name-AIOps" instead of "AIOps", which also prevents sessions from aggregating with the same project recorded by other harnesses. Normalize underscores alongside whitespace, and add a regression test covering a path component with underscores.

Contributor License Agreement Contribution License Agreement
This Contribution License Agreement (*“Agreement”*) is agreed to by the
party signing below (*“You”*),
and conveys certain license rights to Microsoft Corporation and its
affiliates (“Microsoft”) for Your
contributions to Microsoft open source projects. This Agreement is
effective as of the latest signature
date below.
1. *Definitions*.
*“Code”* means the computer software code, whether in human-readable
or machine-executable form,
that is delivered by You to Microsoft under this Agreement.
*“Project”* means any of the projects owned or managed by Microsoft
and offered under a license
approved by the Open Source Initiative (www.opensource.org).
*“Submit”* is the act of uploading, submitting, transmitting, or
distributing code or other content to any
Project, including but not limited to communication on electronic
mailing lists, source code control
systems, and issue tracking systems that are managed by, or on behalf
of, the Project for the purpose of
discussing and improving that Project, but excluding communication
that is conspicuously marked or
otherwise designated in writing by You as “Not a Submission.”
*“Submission”* means the Code and any other copyrightable material
Submitted by You, including any
associated comments and documentation.
2. *Your Submission*. You must agree to the terms of this Agreement
before making a Submission to any
Project. This Agreement covers any and all Submissions that You, now
or in the future (except as
described in Section 4 below), Submit to any Project.
3. *Originality of Work*. You represent that each of Your Submissions
is entirely Your original work.
Should You wish to Submit materials that are not Your original work,
You may Submit them separately
to the Project if You (a) retain all copyright and license information
that was in the materials as You
received them, (b) in the description accompanying Your Submission,
include the phrase “Submission
containing materials of a third party:” followed by the names of the
third party and any licenses or other
restrictions of which You are aware, and (c) follow any other
instructions in the Project’s written
guidelines concerning Submissions.
4. *Your Employer*. References to “employer” in this Agreement include
Your employer or anyone else
for whom You are acting in making Your Submission, e.g. as a
contractor, vendor, or agent. If Your
Submission is made in the course of Your work for an employer or Your
employer has intellectual
property rights in Your Submission by contract or applicable law, You
must secure permission from Your
employer to make the Submission before signing this Agreement. In that
case, the term “You” in this
Agreement will refer to You and the employer collectively. If You
change employers in the future and
desire to Submit additional Submissions for the new employer, then You
agree to sign a new Agreement
and secure permission from the new employer before Submitting those
Submissions.
5. *Licenses*.
- *Copyright License*. You grant Microsoft, and those who receive the
Submission directly or
indirectly from Microsoft, a perpetual, worldwide, non-exclusive,
royalty-free, irrevocable license in the
Submission to reproduce, prepare derivative works of, publicly
display, publicly perform, and distribute
the Submission and such derivative works, and to sublicense any or all
of the foregoing rights to third
parties.
- *Patent License*. You grant Microsoft, and those who receive the
Submission directly or
indirectly from Microsoft, a perpetual, worldwide, non-exclusive,
royalty-free, irrevocable license under
Your patent claims that are necessarily infringed by the Submission or
the combination of the
Submission with the Project to which it was Submitted to make, have
made, use, offer to sell, sell and
import or otherwise dispose of the Submission alone or with the
Project.
- *Other Rights Reserved*. Each party reserves all rights not
expressly granted in this Agreement.
No additional licenses or rights whatsoever (including, without
limitation, any implied licenses) are
granted by implication, exhaustion, estoppel or otherwise.
6. *Representations and Warranties*. You represent that You are
legally entitled to grant the above
licenses. You represent that each of Your Submissions is entirely Your
original work (except as You may
have disclosed under Section 3). You represent that You have secured
permission from Your employer to
make the Submission in cases where Your Submission is made in the
course of Your work for Your
employer or Your employer has intellectual property rights in Your
Submission by contract or applicable
law. If You are signing this Agreement on behalf of Your employer, You
represent and warrant that You
have the necessary authority to bind the listed employer to the
obligations contained in this Agreement.
You are not expected to provide support for Your Submission, unless
You choose to do so. UNLESS
REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING, AND EXCEPT FOR THE
WARRANTIES
EXPRESSLY STATED IN SECTIONS 3, 4, AND 6, THE SUBMISSION PROVIDED
UNDER THIS AGREEMENT IS
PROVIDED WITHOUT WARRANTY OF ANY KIND, INCLUDING, BUT NOT LIMITED TO,
ANY WARRANTY OF
NONINFRINGEMENT, MERCHANTABILITY, OR FITNESS FOR A PARTICULAR PURPOSE.
7. *Notice to Microsoft*. You agree to notify Microsoft in writing of
any facts or circumstances of which
You later become aware that would make Your representations in this
Agreement inaccurate in any
respect.
8. *Information about Submissions*. You agree that contributions to
Projects and information about
contributions may be maintained indefinitely and disclosed publicly,
including Your name and other
information that You submit with Your Submission.
9. *Governing Law/Jurisdiction*. This Agreement is governed by the
laws of the State of Washington, and
the parties consent to exclusive jurisdiction and venue in the federal
courts sitting in King County,
Washington, unless no federal subject matter jurisdiction exists, in
which case the parties consent to
exclusive jurisdiction and venue in the Superior Court of King County,
Washington. The parties waive all
defenses of lack of personal jurisdiction and forum non-conveniens.
10. *Entire Agreement/Assignment*. This Agreement is the entire
agreement between the parties, and
supersedes any and all prior agreements, understandings or
communications, written or oral, between
the parties relating to the subject matter hereof. This Agreement may
be assigned by Microsoft.

Problem
Claude Code encodes underscores as hyphens when building the project directory name under
~/.claude/projects, butencodeComponentForMatchinsrc/core/parser-claude.tsonly normalized whitespace:A path component containing an underscore can therefore never match a
readdirSyncentry.projectNameFromEncodedstops resolving at the first such level and falls through toresolved = path.join(resolved, rest), which takes the entire unresolved remainder as one segment.Impact
For a home directory of
/home/my_name, the encoded directory-home-my-name-AIOpsfails to match the real foldermy_name, so resolution dies at/homeand every Claude workspace is labeledmy-name-AIOpsinstead ofAIOps.Beyond the cosmetic mislabeling, this breaks cross-harness aggregation: the Codex and OpenCode parsers derive the plain basename, so the same project is counted as two separate workspaces and never reconciles. On one real log set (1010 sessions), this split
AIOpsinto 330 + 40 andcendien-websiteinto 201 + 50 + 7, and inflated the distinct workspace count from 30 to 38.This affects any user whose username or project path contains an underscore.
Fix
Normalize underscores alongside whitespace:
Ambiguity between sibling directories differing only by
_vs-is already mitigated by the existing longest-encoded-form-first sort.Testing
Adds a regression test mirroring the existing spaces test, covering a path component with underscores. Verified it fails on
main(expected 'my-home-dir-proj' to be 'proj') and passes with the fix.parser-claude.test.tspasses 22/22.npm run typecheckandnpm run lintare clean (0 errors). The 7 failures ingithub-app-analytics.test.tsare pre-existing onmainand unrelated.
