Hermes v0.11's `hermes profile` feature gives each profile its own
HERMES_HOME directory: the default profile is ~/.hermes, named
profiles live at ~/.hermes/profiles/<name>/. Each has its own
state.db, sessions/, config.yaml, .env, memories/, cron/, etc.
The active profile is recorded in ~/.hermes/active_profile.
Pre-fix Scarf hardcoded ~/.hermes and ignored active_profile, so
`hermes profile use coder` followed by a Scarf relaunch left Scarf
reading the wrong state.db — the new profile's chat sessions
silently never appeared.
Add HermesProfileResolver in ScarfCore that reads active_profile
and returns the effective home path. HermesPathSet.defaultLocalHome
becomes a static var backed by the resolver; every derived path
(stateDB, sessionsDir, configYAML, memoriesDir, cron paths, plugins,
gateway state, auth.json, etc.) automatically follows the active
profile through the existing `home + suffix` plumbing — no
downstream call sites need to change.
Resolver semantics:
- Absent / empty / "default" file → ~/.hermes (today's behavior)
- Valid profile name pointing to an existing dir → that dir
- Invalid name OR missing target → fall back to ~/.hermes with a
one-line os.Logger warning (so worst case is "Scarf shows what
it always showed")
Validation regex mirrors Hermes's hermes_cli/profiles.py exactly
([a-z0-9][a-z0-9_-]{0,63}). 5-second cache via OSAllocatedUnfairLock
keeps hot-path filesystem hits negligible.
SessionInfoBar gains a leftmost profile chip when not "default" so
users can see which profile Scarf is reading from. Tooltip explains
how to switch (`hermes profile use <name>` + relaunch).
Out of scope (deferred):
- In-app profile picker that writes to active_profile. Switching
mid-session is messy (open ACP processes are bound to whichever
HERMES_HOME spawned them); the reporter's "switch + restart" flow
is what we fix here.
- Remote SSH profile awareness. defaultRemoteHome stays "~/.hermes"
— remote profile selection is a separate, larger feature needing
its own UI.
