#   SOURCE OF TRUTH : /c/Users/fight/Documents/Obsidian Vault
#   MIRROR (git)    : C:/Users/fight/AgentOS/memory-systems/agent-os
#   REMOTE          : Tony_tech/personal-agent-os
#
# The mirror is a generated byte copy of the vault, so the Obsidian vault is
# backed up to Gitea without a second *writable* copy that could drift.
# Never edit the mirror by hand — step 2 rebuilds it from the vault.
#
# SCOPE: only the mirror subtree is staged. The AgentOS repo root holds unrelated
# agent work (agent-comms/, knowledge-base/, scripts/, ...) that must not be
# swept into vault commits — a bare `git add -A` would do exactly that.
# ORDER: commit BEFORE `git pull --rebase`; rebase refuses to run on a dirty tree,
# so pulling first is a silent no-op exactly when a pull is needed and the
# following push gets rejected.
# IDENTITY: passed per-commit with `git -c`, never repo-local config — the AgentOS
# repo is shared by every agent profile, so a repo-local user.name would
# attribute every agent's commits to one agent. Override with VAULT_AGENT=<name>.
