0dfb4234 made every mode-less atomic write follow the process umask for NEW
targets, restoring what open("w")-based writers did. Ten of the folded sites
were not open("w") writers: they created the file through mkstemp and never
chmod'd, so on main a fresh file was 0600 regardless of umask (bot mailboxes,
relay inbox, turn markers, sessions.json, cron jobs/output, banner snapshot,
plugin toolset cache, presets, shell hooks, install id). CI caught the loosening
in tests/tools/test_bot_live_owner_delivery.py (st_mode 0o077 bits set).
Pass mode=0o600 explicitly at those ten sites; the umask default stays for the
sites that were open("w") on main. Invariant test exercises two real writers.
Each copy re-implemented temp+replace by hand and lacked one or more of
fsync, symlink preservation, atomic_replace's Windows-contention retry and
EXDEV/bind-mount fallback, mode preservation, or interrupt-safe temp
cleanup. Three (gateway/session_persistence, cron/suggestions,
agent/shell_hooks) were verbatim inlines of utils._atomic_write; two
modules defined their own directory-fsync helper, now utils.fsync_directory.
plugins/google_meet/_jsonfile.write_json_atomic is deleted (callers use the
canonical helper directly).
Behavior change: every one of these writers now fsyncs the payload, keeps a
pre-existing target's mode, cleans its temp file on BaseException, and
survives Windows AV/indexer contention and cross-device renames the way
config writes already did. cron/suggestions.json is 0600 from creation
(previously chmod'ed after the replace). Skipped on purpose: cron/jobs.py
two-phase staging, gateway/status._write_json_excl (create-only lock),
kanban_transfer staging (not atomic writers); tools/skill_usage.
_write_suppressed_names lives inside a PLUGIN-COMPAT block.
Two multiplex key/store mismatches in the gateway session layer:
- SessionStore._db_for_key resolved legacy agent:main keys to the AMBIENT
store. Named-profile keys were already pinned to profiles/<x>/state.db
(#97309), but a default-profile session touched inside a secondary's
runtime scope (a coalesced async-delegation drain, a cron mirror into a
default chat, a scoped watcher) was written into the secondary's state.db
— the profile_name='<A>' row inside B's store reported in #102157, after
which the routing index and row disagree and the #54878 self-heal drops a
live conversation. Default keys now resolve to _routing_home/state.db, the
launch home already pinned for the routing index. Single-profile gateways
(multiplex off) keep the ambient store byte-for-byte.
- /undo evicted the cached agent under build_session_key(source) —
agent:main:… — while the cache is keyed by the profile namespace, so on a
secondary profile the eviction missed and the next turn reused an agent
whose in-memory history still held the undone turns. Use
_session_key_for_source like /reset and /retry.
Addresses #102157.
Merge upstream b1f003e186 while preserving PM runtime ownership and
Python 3.14 worker startup, Windows signing, and macOS wait recovery.
Keep retired runtime modules deleted. Port upstream updater preflight
checks into the checkout strategy and preserve live build logging.
Carry checkpoint filename handling and process recovery into the current
module layout. Regenerate locks and adapt incoming platform test markers.
Focused Python and JavaScript tests, desktop and root-test typechecks,
conflict-path lint checks, lock validation, and retired-import checks pass.
The full test suite and packaged release builds were not run.
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).
Re-applies the gateway compat removal byte-for-byte; see 92d0bd0d73 for the
full inventory (30 re-exports/aliases + 2 shim modules dropped, 3 shim-only
names re-removed, 24 callers + 34 test files repointed). No new changes.
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.
