get_password_hash() computes PBKDF2-SHA256 with 600k iterations to
hash the HERMES_WEBUI_PASSWORD env var. This is called on nearly every
HTTP request via check_auth -> is_auth_enabled -> get_password_hash.
Before: ~1s of PBKDF2 per request, regardless of how many times the
same env-var value has already been hashed. A page load hitting 5+
API endpoints would burn 5+ seconds purely on password hashing.
After: compute once on first call, cache the hex result in a module-
level variable. Subsequent calls are a single global-variable read
(~50ns). The env var is immutable for the process lifetime, so there
is nothing to invalidate.
Thread-safe: double-checked locking ensures that under a burst of
concurrent requests only one thread computes PBKDF2, while the fast
path (after initialisation) requires zero locks.
10 unit tests covering all branches, cache-lifetime semantics, and
concurrent burst safety (8 threads, exactly 1 PBKDF2 call).
Test isolation: reloads only api.auth via importlib.reload, leaving
api.config untouched so test_pytest_state_isolation.py is unaffected.
Security analysis: zero regression. The hash is derived from a static
env var and a static signing key — both already readable from process
memory. Caching does not introduce any new disclosure or replay
vector. PBKDF2 is still used for the initial computation and for
verify_password() on login.

feat: add manual provider usage refresh (Jordan-SkyLF)
Adds a 'Refresh usage' button on the Provider quota card in Settings → Providers,
with cache: 'no-store' fetch + browser cache-bust query string. Pure browser-side
cache-busting; the server-side /api/provider/quota endpoint has no cache layer
yet (refresh=1 query param is currently a no-op server-side; the win is bypassing
browser/proxy/SW caches).
fix: guard stale stream writebacks (LumenYoung)
Prevents stale WebUI stream workers from writing old results into a session
after that session has already moved on to another stream. Adds new helper
_stream_writeback_is_current() (a token equality check against the session's
active_stream_id) and short-circuits the two finalize/cancel paths when the
worker no longer owns the session writeback.
(1) compress/status no longer pops the job entry on first read of `done` payload.
Second open tab no longer sees `idle` and a stale-job toast.
(2) compress/start no longer short-circuits to a stale `done` payload when
re-invoked within the 10-minute TTL. Re-running /compress always starts
fresh, so closing-and-reopening a tab mid-compress works correctly.
Third SHOULD-FIX (#2135 cfg["model"] fallback tightening when no custom_providers
entry matches) deferred to follow-up — strictly no-worse-than-master behavior.
tests/test_sprint46.py 10/10 still passes.
#2142 (legeantbleu) added the fr locale to static/i18n.js but didn't update:
1. tests/test_issue1488_composer_voice_buttons.py: two TestComposerVoiceButtonI18n + TestVoiceModePreferenceGate LOCALES tuples needed 'fr'
2. api/routes.py: _LOGIN_LOCALE needed an 'fr' block so the login page localizes for French users (issue #1442 parity contract)
3. tests/test_login_locale_parity.py: the test asserting 'fr' falls-back-to-'en' is inverted — fr now resolves to fr, with sibling assertions for fr-FR and fr-CA
Mirrors the stage-340 fix for the it locale (PR #2067 → maintainer adds tuple entries). 46/46 i18n tests pass after fix.
