Every PLUGIN-COMPAT __getattr__ now calls hermes_cli.plugin_compat.warn_once(facade, name, target) before
resolving, emitting a HermesPluginCompatWarning (FutureWarning) once per process per name: old path, new
path, removal target. Importing a facade for its live API stays silent; only resolving a moved name warns.
COMPAT_MANIFEST.md documents the warning and how to silence it during migration.
Verified the runtime never routes through a pointer: every entry point (run_agent, cli, hermes_cli.main,
gateway.run, tui_gateway.server, web_server, model_tools + tool discovery, hermes_state, cron.scheduler,
browser_tool, mcp_tool, kanban, auth) imports clean and `hermes doctor` runs end to end with the warning
promoted to an error.
Also restores the check_compat_pointers CI step to .github/workflows/lint.yml, which a0be177aac dropped
when the compat layer was regenerated (the lint script itself was present; the workflow step was not).
hermes_cli/plugin_compat.py, tests/test_plugin_compat_warning.py and the two-line insert per facade are
part of the compat layer and go away with it.
The Sep 2026 decomposition (PR #102117) makes internal import paths a non-API: names now live in
the focused modules that define them. This commit is the ONLY thing keeping the old paths alive,
so external plugins have time to update. It is deliberately a single, unsquashed commit:
git revert <this sha>
removes every shim, stub and manifest at once on the announced date. Nothing in-tree may depend on
these pointers: scripts/check_compat_pointers.py (wired into lint.yml) fails CI if it does.
What it adds (see COMPAT_MANIFEST.md, compat_manifest.json):
- 332 facade modules get one delimited `PLUGIN-COMPAT` block appended at the end of the file
- 1,172 moved names resolved lazily via a module `__getattr__` (PEP 562) — never a top-level import,
so no import cycles; facades that already had `__getattr__` get a chained one
- 592 third-party/stdlib names the old modules used to expose, with their original import statements
- 266 public definitions that had been deleted as unused, restored byte-for-byte from the pre-decomposition
tree (+40 private helpers and 16 imports pulled in only because a restored definition needs them)
- 3 deleted modules recreated as re-export stubs (gateway/startup_watchdog, hermes_cli/observability/
relay_runtime, tools/environments/modal_utils)
- private names (`_x`) get no pointer: they were never API (3,792 skipped)
Verified: all 335 touched modules import under a fresh HERMES_HOME and every manifest name resolves;
the lint reports zero in-tree uses; ruff clean; targeted suites unchanged.
Choosing Computer Use should be a config flip, not a hunt for
'hermes computer-use install'. Three provisioning rungs:
- install.sh / install.ps1 pre-install cua-driver (best-effort,
non-fatal, time-boxed at 660s above the upstream installer's 600s
lock window; --skip-computer-use / -SkipComputerUse to opt out;
Termux and unwritable-/Applications skipped cleanly)
- PUT /api/tools/toolsets/{name} (dashboard + desktop toggle) spawns
the background 'hermes tools post-setup cua_driver' action when the
toolset is enabled while the binary is missing — previously the
toggle 'saved' but the tool never appeared in the schema because
check_computer_use_requirements() couldn't find the binary
- hermes tools interactive flow already installed via
_toolset_needs_configuration_prompt/_POST_SETUP_INSTALLED (unchanged)
Docs: computer-use.md enabling section rewritten around the new flow;
installation.md documents --skip-computer-use.
Two follow-ups to the off-loop move, from external review (both verified,
the second larger than reported):
- Config read-modify-write handlers moved to worker threads could now
interleave — _CONFIG_LOCK covers each load/save individually, never the
span between them; the event loop used to serialize these accidentally.
New _CONFIG_MUTATION_LOCK (worker-threads only, so it can never block
the loop) held across the whole load→mutate→save span in all seven RMW
handlers. update_config_raw skipped: it's a full-document replace with
no server-side read, so a lock cannot close its client-side window.
- The review flagged two skills routes still taking _SKILLS_PROFILE_LOCK
on the event loop; a systematic audit of hermes_cli/web_routers/ found
24 on-loop routes (skills 5, mcp 9, tools 10, cron 1). All moved to the
same inner-_run + asyncio.to_thread pattern, mutating ones under the
mutation lock, uniform lock order (_SKILLS_PROFILE_LOCK →
_CONFIG_MUTATION_LOCK). Await-safe _config_profile_scope routes, plain
def routes, and already-threaded routes unchanged.
Regression tests: concurrent theme+font updates both survive (fails with
the lock nulled: "theme write lost to a concurrent font write"); event
loop stays responsive while the profile lock is held during GET
/api/skills. 214 tests passing across the touched suites.

- hermes_cli/web_routers/sessions.py: 14 routes across 3 routers
(list_router, search_router, manage_router) mounted at the three original
registration points so global route order is preserved exactly.
- hermes_cli/web_routers/mcp.py: 11 routes; OAuth flow registry
(_mcp_oauth_flows/lock/cap) stays in web_server, reached via new
web_deps.LateState live proxies so tests mutating web_server._mcp_oauth_flows
keep working.
- hermes_cli/web_routers/skills.py: 12 routes across hub_router + router
(two original registration points straddle the profiles router include).
- hermes_cli/web_routers/tools.py: 12 routes; toolset/terminal catalogs stay
in web_server (some are defined after the mount point), reached via LateState.
- web_deps.py: add LateState — operation-time proxy for web_server-owned
module state (getattr/item/iter/len/contains/context-manager/comparisons).
- Handler bodies byte-identical; legacy re-exports keep
web_server.<handler> importable for tests.
- Verified: ordered route table (method, path) identical to pre-refactor app
(291 routes); import smoke; ruff; windows-footguns clean.
- test_web_server_sessiondb_eventloop.py: structural AST scan now reads both
web_server.py and web_routers/sessions.py (handlers moved; helpers stayed).
