Move the general-vs-memory hook ownership logic out of the memory collector into
PluginLedgerMixin (_drop_fallback_hooks / _register_fallback_hook) so the collector
and the loader each call one manager method instead of reaching into manager privates.
Hoist hashlib to module scope. Trim the new suite to the three invariant cases
(run-once across load orders, distinct sources not suppressed, re-exported register).
The plugin loader pre-registers empty shells in sys.modules before
executing any submodule. When _setup.py ran 'from . import _read_mem0_json'
at module level, Python found the empty parent shell (init not yet executed),
so the import failed silently. This left _setup.py partially loaded and
post_setup undefined, causing 'cannot import name post_setup' during
hermes memory setup mem0.
Move the import inside the three functions that use it, matching the
late-import pattern __init__.py already uses for post_setup.
Fixes: hermes memory setup mem0 crashing with ImportError
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.
Review findings on #102117 (independent reviewer + itsflownium):
* hermes_cli.kanban_db.connect / connect_closing pointed at hermes_cli.projects_db (different DB, no
board= parameter). The compat generator ranked candidate homes by path proximity when a name is
defined in several modules. Now it requires shape compatibility with the BASE definition (same
literal for constants, superset of parameter names for defs) and prefers the facade's own
<stem>_* sibling. Same class fixed for tools.tts_tool.DEFAULT_XAI_BASE_URL (-> tts_tool_providers),
and 17 constants/defs that had been pointed at same-named strangers (Matrix MAX_MESSAGE_LENGTH ->
Signal's 8000, tts MAX_TEXT_LENGTH -> BlueBubbles', honcho/retaindb/supermemory *_SCHEMA -> another
plugin's schema, ...) are now restored from BASE verbatim instead.
* send_yuanbao_direct (restored-def): body called adapter._outbound.send_direct, which HEAD moved to
the sender; rewritten to adapter._outbound.sender.send_direct.
* COMPAT_MANIFEST.md states the scope explicitly: public top-level names only; private names and
test monkeypatch seams are not preserved.
* scripts/check_subprocess_stdin.py: _splat_carries_stdin looked 30 lines ahead in the file text
and was satisfied by an unrelated later stdin=; it now finds the splatted name's definition via AST
and requires stdin inside that expression/body.
Tests: tests/test_compat_manifest_targets.py (pointer identity vs the facade's sibling; kanban
connect(board=) opens a Kanban DB, not projects.db; both FAIL on the previous layer),
test_subprocess_stdin_guard gains the false-negative probe, and the MoA -Q quiet-output contract
tests are back (tests/agent/test_moa_quiet_reference_output.py) against build_moa_facade.
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.
No runtime consumer read the proxy (terminal_tool/environments call is_interrupted()/set_interrupt()
directly); its only users were tests patching tools.interrupt._interrupt_event, which had no effect on
the code under test. tools/terminal_tool.py's own re-export of the name is owned by another worker.
hermes_state.py: delete every '# noqa: F401 (re-exported...)' import block (hermes_state_common/errors/guard/
readpool/sessions/fts/dbfile/wal/repair/registry + agent.context_compressor _DB_PERSISTED_MARKER_KEY); keep
only the names hermes_state.py itself uses, without noqa.
hermes_state_registry.py: drop get_shared_session_db/release_shared_session_db/close_shared_session_dbs
aliases; every caller (gateway/, tools/, tui_gateway/, cron/, mcp_serve, run_agent, tests) now imports
acquire/release/close_all/release_or_close from hermes_state_registry.
hermes_state_titles.py: drop set_auto_title_if_empty shim (title_generator keeps its getattr fallback).
Re-remove shim-only names restored by 34abf954bd: latest_user_message_row_id (tests call
latest_message_row_id(key, role='user'); role-targeting assertions kept) and get_session_activity (tests
build the snapshot via agent.session_activity.build_activity_snapshot over db.get_session(sid)).
hermes_state_wal._log_once resolves its dedupe sets as module globals instead of via hermes_state;
hermes_state_repair helpers call module globals directly (tests patch hermes_state_repair.<name>).
Frozen updater surface untouched (update_cmd_maint imports only SessionDB from hermes_state).
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
Repo scanners (check_subprocess_stdin, check-windows-footguns --all) flagged 21 sites where
the r3 single-line collapses lost stdin=DEVNULL, encoding='utf-8'/errors='replace', the
'# windows-footgun: ok' same-line marker, or the getattr(os, 'geteuid') gate. Each guard is
restored at the call site (real portability/hang fixes, not suppressions).
