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.
- Migrate the missed 6th inline formatter (update_cmd.py backup-size
display) to the shared helper.
- checkpoints._fmt_bytes: plain alias instead of a None-guard wrapper —
every caller feeds ints from checkpoint_manager (all size fields
initialize to 0), so the None path was dead defensive code.
- Drop the fallback= kwarg (zero production callers; '?' default is the
real inherited contract and stays).
- curator_backup + context_references: call format_bytes directly (single
internal call site each, zero external importers — alias was churn
avoidance with nothing to avoid). backup/_format_size and
doctor/_human_bytes keep their aliases (claw.py + tests pin the former;
three call sites use the latter).
- Reshape the loop so the trailing TB return is reachable (no dead line).
- Tests: replace alias-identity assertions (ossified the delegation
mechanism) with behavior-contract equality over a value sweep;
mutation-checked red-green.
- update_cmd parity: byte-identical B-GB vs the old inline loop; gains
the TB tier.
Five modules each carried a private near-identical human-readable byte
formatter (backup._format_size, checkpoints._fmt_bytes,
doctor._human_bytes, context_references._human_bytes,
curator_backup.format_size). Three of them silently topped out at GB and
rendered a 1 TiB value as '1024.0 GB'. All five now alias one shared
format_bytes in hermes_cli/sizefmt.py (sibling of timefmt.py, same
zero-dependency rationale), keeping each module's established local name
so no caller churns.
Deliberately NOT migrated (behavior differs on purpose):
- session_recovery._format_bytes: binary suffixes (KiB/MiB/GiB)
- qqbot chunked_upload.format_size: '100.0 B' one-decimal style, pinned
by its protocol tests
Net -33 production LOC before the new module; parity verified over a
16-value corpus against all five verbatim originals (only divergence:
the TB tier fix). Contract tests mutation-checked red-green.
Follow-up for salvaged PR #69141, addressing the last open review point:
cmd_prune() only set orphan_allowlist inside 'if orphans or pre_v2_orphans',
so a zero-orphan preview passed the unrestricted None sentinel down to
prune_checkpoints(), authorizing deletion of any project that became
orphaned between the preview and the rescan — with zero confirmation
calls. The allowlist is now bound unconditionally for every non-force
run (empty preview => empty allowlist); --force keeps None. Adds the
zero-orphan-preview timing regression plus allowlist-identity tests.
Address P1 from PR review: cmd_prune()'s y/N preview reads
store_status() but the confirmed deletion re-scans both the v2 and
pre-v2 layouts from scratch. A workdir that goes missing while the
human is answering the prompt gets swept in as if it had been shown
and approved.
prune_checkpoints() now accepts orphan_allowlist — a set of v2 project
hashes and/or pre-v2 shadow repo paths. When set, only orphans whose
identity is in the set are deleted; anything newly orphaned since the
scan survives the run. cmd_prune() builds this set from the exact
projects it just displayed and passed confirmation for. --force still
passes None (no preview shown, so nothing to bind to).

store_status()["projects"] only ever covered v2 metadata, so the
`hermes checkpoints prune` confirmation prompt was blind to pre-v2
base/<hash>/HEAD shadow repos that prune_checkpoints() deletes
separately via shutil.rmtree — a pre-v2-only or mixed store could
lose checkpoint history without ever hitting the confirmation.
Extract the pre-v2 scan into _pre_v2_shadow_repos() and have both
store_status() (preview, new pre_v2_projects key) and
prune_checkpoints() (deletion) read from it, so the CLI prompt can
no longer diverge from what actually gets removed.

Builds on this PR's diagnosis by @Frowtek: a missing workdir is
ambiguous (deleted project vs. an unmounted external volume / network
share / VPN not yet up), so it's not safe evidence for a destructive
GC sweep — especially one that runs unattended at startup.
- cli.py / gateway/run.py: the startup auto-maintenance sweep now
always passes delete_orphans=False to maybe_auto_prune_checkpoints().
It still prunes by retention_days, size cap, and legacy archives —
none of which require guessing whether a project was deleted or is
just temporarily unreachable.
- hermes_cli/config.py: drop the now-unused delete_orphans default.
- hermes_cli/checkpoints.py: `hermes checkpoints prune` (the explicit,
human-invoked path) now previews the orphan project list and asks
for confirmation before deleting, unless -f/--force is passed.
- Docs updated (EN + zh-Hans) to match.

Remove unused imports (F401) and duplicate/shadowed import
redefinitions (F811) across the codebase using ruff's safe
autofixes. No behavioral changes -- imports only.
- ~1400 safe autofixes applied across 644 files (net -1072 lines)
- __init__.py re-exports preserved (excluded from F401 removal so
public re-export surfaces stay intact)
- Re-exports that are imported or monkeypatched by tests but look
unused in their defining module are kept with explicit # noqa:
F401 (gateway/run.py load_dotenv; run_agent re-exports from
agent.message_sanitization, agent.context_compressor,
agent.retry_utils, agent.prompt_builder, agent.process_bootstrap,
agent.codex_responses_adapter)
- Unsafe F841 (unused-variable) fixes deliberately skipped -- those
can change behavior when the RHS has side effects
- ruff lints remain disabled in pyproject.toml (only PLW1514 is
selected); this is a one-time cleanup, not a config change
Verification:
- python -m compileall: clean
- pytest --collect-only: all 27161 tests collect (zero import errors)
- core entry points import clean (run_agent, model_tools, cli,
toolsets, hermes_state, batch_runner, gateway)
- static scan: every name any test imports directly from an edited
module still resolves
Replace with for all literal-tuple
membership tests. Set lookup is O(1) vs O(n) for tuple — consistent
micro-optimization across the codebase.
608 instances fixed via `ruff --fix --unsafe-fixes`, 0 remaining.
133 files, +626/-626 (net zero).
Replaces the per-directory shadow-repo design with a single shared shadow
git store at ~/.hermes/checkpoints/store/. Object DB is now deduplicated
across every working directory the agent has ever touched; a dozen
worktrees of the same project cost near-zero in additional disk.
Why
---
Pre-v2 design had three compounding problems that let ~/.hermes/checkpoints/
grow to multi-GB on active machines:
1. Each working directory got its own full shadow git repo — no object
dedup across projects or across worktrees of the same project.
2. _prune() was a documented no-op: max_snapshots only limited the
/rollback listing. Loose objects accumulated forever.
3. Defaults: enabled=True, auto_prune=False — users paid the disk cost
without ever asking for /rollback.
Field report on a single workstation: 847 MB across 47 shadow repos,
mostly redundant clones of the hermes-agent source tree.
Changes
-------
- tools/checkpoint_manager.py: full rewrite. Single bare store, per-project
refs (refs/hermes/<hash>), per-project indexes (store/indexes/<hash>),
per-project metadata (store/projects/<hash>.json with workdir +
created_at + last_touch). On first v2 init, any pre-v2 per-directory
shadow repos are auto-migrated into legacy-<timestamp>/ so the new
store starts clean. _prune() now actually rewrites the per-project ref
to the last max_snapshots commits and runs git gc --prune=now. New
_enforce_size_cap() drops oldest commits round-robin across projects
when the store exceeds max_total_size_mb. _drop_oversize_from_index()
filters any single file larger than max_file_size_mb out of the snapshot.
- hermes_cli/checkpoints.py: new 'hermes checkpoints' CLI
(status / list / prune / clear / clear-legacy) for managing the store
outside a session.
- hermes_cli/config.py: flipped defaults — enabled=False, max_snapshots=20,
auto_prune=True. Added max_total_size_mb=500, max_file_size_mb=10.
Tightened DEFAULT_EXCLUDES (added target/, *.so/*.dylib/*.dll,
*.mp4/*.mov, *.zip/*.tar.gz, .worktrees/, .mypy_cache/, etc.).
- run_agent.py / cli.py / gateway/run.py: thread the new kwargs through
AIAgent and the startup auto_prune hooks.
- Tests rewritten to match v2 storage while keeping backwards-compat
coverage for the pre-v2 prune path (per-directory shadow repos under
base/ are still swept correctly for anyone mid-migration).
- Docs updated: user-guide/checkpoints-and-rollback.md explains the
shared store, new defaults, migration, and the new CLI;
reference/cli-commands.md documents 'hermes checkpoints'.
E2E validated
-------------
- Legacy migration: pre-v2 shadow repos auto-archived into legacy-<ts>/.
- Object dedup: two projects with an identical shared.py blob resolve to
7 total objects in the store (v1 would have stored the blob twice).
- max_snapshots=3 actually enforced: after 6 commits, list shows 3.
- Orphan prune: deleting a project's workdir + 'hermes checkpoints prune
--retention-days 0' removes its ref, index, and metadata; GC reclaims
the objects.
- max_file_size_mb=1 excludes a 2 MB weights.bin while keeping the
tracked source code files.
- hermes checkpoints {status,prune,clear,clear-legacy} all work from the
CLI without an agent running.
Breaking / migration
--------------------
No in-place data migration — legacy per-directory shadow repos are moved
into legacy-<timestamp>/ on first run. Old /rollback history is still
accessible by inspecting the archive with git; run
'hermes checkpoints clear-legacy' to reclaim the space when ready. Users
relying on /rollback must now set checkpoints.enabled=true (or pass
--checkpoints) explicitly.
