The slug-migration fallback (used when there is no live symlink to read the previous slug from) recomputed the local-* candidate by lowercasing the basename only, while _agents_repo_slug sanitizes it. The two formulas had drifted, so the fallback silently found nothing for any project directory whose basename needed sanitizing. Extract the formula into a single private helper, _agents_repo_local_slug, and have both _agents_repo_slug's no-remote branch and agents-vault's migration fallback call it, so there is one place left to drift. Also drop two dead lines the review flagged: an unused local, and an unreachable mkdir -p (path dirname ...) — slugs never contain a path separator, so dirname always resolves to a directory that already exists by that point. Widen migration test coverage: the current-entry-present-but-empty case, a remote URL rewrite, a remote removal, and a dirty-basename fallback test that fails without the sanitization fix and passes with it.

# SYNOPSIS
|
|
# _agents_repo_slug <dir>
|
|
#
|
|
# DESCRIPTION
|
|
# Derives the vault slug for a project directory. Prefers the normalized
|
|
# git remote URL so the same project keys identically from any clone on
|
|
# any machine; falls back to a path-derived key when no remote exists.
|
|
#
|
|
# Normalization strips the scheme, userinfo, and a numeric port, rewrites
|
|
# scp-form host:path to host/path, drops a trailing .git, lowercases, and
|
|
# maps every character outside [a-z0-9._-] to a dash. These all yield
|
|
# git.rootiest.dev-rootiest-fish-config:
|
|
#
|
|
# https://git.rootiest.dev/rootiest/fish-config.git
|
|
# git@git.rootiest.dev:rootiest/fish-config.git
|
|
# ssh://git@git.rootiest.dev:22/rootiest/fish-config.git
|
|
#
|
|
# With no remote the slug is local-<sanitized-basename>-<8 hex of sha256(realpath)>,
|
|
# where the basename is lowercased and mapped the same way as the remote form.
|
|
# That key is machine-dependent by construction and is best-effort only;
|
|
# agents-vault --adopt rebinds such an entry by hand.
|
|
#
|
|
# ARGUMENTS
|
|
# dir Absolute path to the project directory
|
|
#
|
|
# EXIT STATUS
|
|
# 0 Slug printed
|
|
# 1 No directory argument given
|
|
#
|
|
# RETURNS
|
|
# The slug, one line on stdout.
|
|
#
|
|
# EXAMPLE
|
|
# set -l slug (_agents_repo_slug /home/user/myproject)
