Installing a memory provider (Honcho, mem0, hindsight, ...) from the dashboard Plugins page failed on hosted deployments with a permission error: the setup endpoint shelled out to `uv pip install --python sys.executable`, which targets the sealed read-only venv under /opt/hermes (immutable hosted image, NS-579/#49113). The correct mechanism already exists: tools/lazy_deps.py redirects installs to the writable durable target on the data volume (HERMES_LAZY_INSTALL_TARGET=/opt/data/lazy-packages) when the venv is sealed (HERMES_DISABLE_LAZY_INSTALLS=1), appends the target to the END of sys.path (core venv always wins collisions), and constrains shared deps to core-venv versions. The dashboard installer simply never used it. Fix: - tools/lazy_deps.py: new public install_specs() — installs arbitrary manifest-declared pip specs through the same environment routing as ensure(): venv-scoped by default, durable-target on sealed images, refused with an actionable reason when gated off (config kill switch or sealed venv without a target — never surfaces raw EROFS/EACCES). Specs are validated with _spec_is_safe(); post-install it invalidates import/metadata caches so availability rechecks in the same process see the new packages without a restart. Never raises. - hermes_cli/web_server.py: _install_memory_provider_pip_dependencies now calls install_specs() instead of building its own uv/pip subprocess. Blocked installs surface the gate reason in the setup results; the response's status block reflects post-install availability (stale 'missing deps' state clears immediately). - hermes_cli/memory_setup.py, plugins/memory/honcho/cli.py, plugins/memory/mem0/_setup.py: CLI setup wizards routed through install_specs() too — same sealed-venv failure mode, same fix. No hosted setup path writes to /opt/hermes anymore; provider discovery and installation now use the same environment (sys.path activation is shared with the lazy-install bootstrap in hermes_bootstrap). Tests: - tests/tools/test_lazy_deps.py: TestInstallSpecs — gating matrix (sealed+no-target blocked with immutable-deployment reason, config kill switch, sealed+target proceeds), spec-safety rejection before any subprocess, venv-scoped vs --target command display, failure stderr passthrough, never-raises contract. - tests/hermes_cli/test_web_server.py: setup endpoint routes pip through lazy_deps (regression guard asserts no direct 'pip install' subprocess), blocked-reason surfacing, same-response availability recheck clears stale missing state. Fixes NS-605 (Plain T-1111). |
