After a successful password change, revoke all browser sessions for the
same user except the one that submitted the request. This prevents stale
sessions on other devices from remaining valid after credentials are
updated.
Keep API-token behavior unchanged. The current browser session is
preserved so the user can continue from the tab that changed the
password.
Add focused regression tests for preserving the current session, revoking
other sessions, persisting revocation, and avoiding revocation when the
current password is incorrect.
`core.middleware.require_admin` grants admin to any request whose
`request.state.current_user == "internal-tool"` — the sentinel meant only
for the in-process tool-loopback path. But the normal cookie auth path
(app.py) sets `current_user` to the raw username, and neither `create_user`
nor the signup route reserved that name. As a result an account literally
named "internal-tool" was silently treated as admin by every
`require_admin`-gated route. With self-service signup enabled this is an
anonymous -> admin privilege escalation.
Reserve the full synthetic-owner set the codebase already special-cases —
"internal-tool", "api", "demo", "system" (see `_SYNTHETIC_OWNERS` in
routes/assistant_routes.py and the matching guards in src/task_scheduler.py
and routes/research_routes.py). "api" collides with the bearer-token owner
sentinel; "demo"/"system" would leave a real account denied an assistant
and inconsistently owner-scoped.
Refuse to create or rename into any reserved name (case/space-normalized),
and reject empty usernames while we're here. Adds a regression test.

Require admin access before serving provider discovery data from
GET /api/providers. This prevents normal authenticated users from
triggering provider discovery or receiving cached provider host data.
Keep GET /api/models available to normal users and leave the existing
admin-only GET /api/discover behavior unchanged.
Add a focused regression test to ensure unauthorized callers cannot
trigger discovery and cannot receive cached provider data.
The synchronous llm_call() runs in FastAPI's threadpool (sync route
handlers such as POST /sessions/auto-sort), while llm_call_async() runs
on the event loop. Both mutate the module-level _response_cache,
_host_fails and _dead_hosts dicts, so these are touched from multiple OS
threads concurrently. Two races result:
- _set_cached_response() snapshots 64 keys then deletes them with
`del _response_cache[key]`; if another thread evicts the same key
first, the del raises KeyError mid-eviction. Switched to
pop(key, None).
- _mark_host_dead() does get()+1+set() on _host_fails with no lock, so
concurrent connect failures lose increments and a genuinely dead host
can stay under its cooldown threshold. Guarded the host-health maps
with a threading.Lock (also applied to _is_host_dead / _clear_host_dead
for consistent reads).
Adds tests/test_llm_core_concurrency.py with deterministic regression
tests (phantom snapshot key for the eviction race; a slow-read dict that
forces the lost-update window for the counter). Both fail on the
unpatched code and pass with the fix.
The email auto-calendar pass (settings.email_auto_calendar / the
extract_email_events task) scans recently received mail and lets an LLM
create / update / cancel calendar events. Two problems made it a cross-tenant,
remotely triggerable hole:
1. No owner scoping. _auto_summarize_pass(account_id=None) fans out over EVERY
enabled account of EVERY user. For each message it fetched an upcoming-events
snapshot with NO owner filter (all tenants' events) and handed those uids +
titles to the extraction LLM, then executed the model's ops via
do_manage_calendar(...) with owner=None. do_manage_calendar only filters by
owner when owner is not None, so create/update/delete ran across ALL users'
calendars. Net: every user's event titles/times were disclosed to the model,
and the model could cancel/move/duplicate any tenant's events by uid.
2. No prompt-injection wrapping. The raw email From/Subject/body were
interpolated straight into an instruction-shaped extraction prompt (unlike
the chat path, which wraps external text via src/prompt_security). Anyone
who can email a user whose instance has auto-calendar enabled could inject
operations: create attacker-controlled "meeting" events (the path even
auto-harvests URLs from the body into the event location/description — a
phishing primitive) or cancel/modify the victim's real events, with zero
human in the loop.
Fix:
- Add core.database.get_upcoming_events(owner) and use it for the snapshot, so
the LLM only ever sees the processed account owner's events.
- Look up the EmailAccount owner in _auto_summarize_pass_single and pass owner=
to every do_manage_calendar call, so create/update/delete are scoped to that
user (owner=None stays the single-user / legacy escape hatch).
- Tell the extraction model the email is untrusted data and not to follow
instructions inside it (defense-in-depth against injection).
Add tests/test_calendar_owner_scope.py: get_upcoming_events returns only the
given owner's events (and everything when owner is None). Fails against the old
unscoped query.
* fix: run bcrypt off the event loop in auth routes
The auth routes are async, but each bcrypt call ran synchronously on the event
loop. bcrypt (checkpw/hashpw) is intentionally CPU-expensive (~100-300 ms), so
every login / signup / setup / change-password froze the single event loop for
that window, stalling all other in-flight requests (chat streams, polling, ...).
/api/auth/login is the worst case: it is reachable unauthenticated, runs bcrypt
twice (verify_password, then create_session re-verifies), and is rate-limited
only per-IP. A burst of login attempts serializes the whole server — cheap
DoS amplification.
Offload the bcrypt-bearing AuthManager calls (setup, signup/create_user,
login's verify_password + create_session, change_password) via
asyncio.to_thread, matching how the codebase already offloads blocking work
(e.g. src/builtin_actions._run_subprocess, email summarize). The event loop
stays responsive while bcrypt runs on a worker thread.
Add tests/test_auth_event_loop.py: asserts login runs verify_password and
create_session on a worker thread, not the loop thread. Fails if those calls
are awaited inline again.
* test: isolate auth event-loop test from heavy core/* import chain
The regression test imported routes.auth_routes, which pulls in
core.auth and so triggers core/__init__.py — transitively importing
src.llm_core (hangs at import under the project venv) and the SQLAlchemy
declarative models (metaclass error on a bare core.database import / under
the conftest sqlalchemy stubs). Reported by the maintainer: collection
failed on system Python and hung under the venv.
Stub core.auth/core.database before the import, mirroring the existing
_ensure_stub pattern in test_auth_regressions.py and test_null_owner_gates.py.
AuthManager is only a type hint here and the handler is exercised with a
MagicMock, so no real core machinery is needed. Test now imports cleanly
and passes in <0.3s without bcrypt/sqlalchemy installed.
/api/auth/settings is auth-exempt (the frontend + the pre-login page read it for
keybinds/TTS prefs), so non-admin and unauthenticated callers get a scrubbed
copy. The previous scrub only blanked TOP-LEVEL string values whose key matched a
short suffix list — so a secret nested under a non-secret parent key, or stored
under a key outside the list, would leak. A real exposure when the app is
reachable over a Cloudflare tunnel / reverse proxy.
- src/settings_scrub.py: NEW stdlib-only module with the scrub helpers (deep/
recursive; broadened secret-key patterns). Kept separate from auth_routes so it
imports + unit-tests WITHOUT pulling the FastAPI / auth / database chain
(addresses review: the test no longer fails at collection on the DB import).
- routes/auth_routes.py: import scrub_settings from the module.
- tests/test_settings_scrub.py: import the tiny module directly.
Ran: pytest tests/test_settings_scrub.py (8 passed); verified the test pulls no
db/auth modules into sys.modules; py_compile routes/auth_routes.py.

Hardens issues found in a security review of the current tree (separate from
the cookbook SSH PR):
- Email thread rendering (static/js/emailLibrary.js): the flat read path runs
inbound HTML through the allowlist sanitizer, but the two threaded paths
(_renderTurnsAsBubbles / _renderTurnsFromServer — the default view) injected
server-parsed `body_html` raw into the DOM. A crafted inbound email could
inject arbitrary markup (phishing/form/credential-capture/tracking; full XSS
if a deployment relaxes the script CSP). Now sanitized on all paths.
- Attachment extraction (routes/email_routes.py, routes/email_helpers.py): the
on-disk extraction dir was `ATTACHMENTS_DIR / f"{folder}_{uid}"` with
user-controlled folder/uid and no containment, so a folder like `../../tmp`
could escape ATTACHMENTS_DIR. New attachment_extract_dir() flattens both to a
single safe segment and asserts containment.
- Diagnostics routes (routes/diagnostics_routes.py): /api/db/stats,
/api/rag/stats, /api/test/youtube, /api/test-research relied only on the
global session check (any logged-in user). Now require_admin-gated.
- Defense-in-depth HTML escaping: session HTML export escapes the session name
(routes/session_routes.py); the MCP OAuth page escapes the reflected Host
header / server_id (routes/mcp_routes.py).
- Internal-tool token now compared with secrets.compare_digest (constant time)
in core/middleware.py and app.py.

hardware.py detects Apple Silicon locally and over SSH, reporting
backend=metal, the chip name, and a RAM-scaled fraction of unified

table for realistic tok/s and drops vLLM-only formats (AWQ/GPTQ/FP8)
that can't be served on Metal.

* Generate macOS/Metal serve commands and surface the Metal GPU
cookbook_routes.py adds a macOS serve path (Ollama, Metal-aware
llama.cpp build using `sysctl hw.ncpu` instead of `nproc`, and a clear
error if vLLM is attempted). The frontend defaults Metal serving to
llama.cpp and offers llama.cpp/Ollama instead of vLLM/SGLang. The
odysseus-cookbook CLI's `gpus` command reports the Metal GPU via
sysctl/vm_stat.

* Add downloadable macOS launcher app builder
build-macos-app.sh generates dist/Odysseus.app and a drag-to-Applications
dist/Odysseus.dmg. The app starts the local server from this repo's venv and
opens the UI in a chrome-less app window (Chromium --app mode, falling back to
the default browser). It's a launcher wrapper — it drives the venv rather than
bundling Python — so the install path is baked in at build time.

* Harden macOS Cookbook support: hide MLX, fix Metal build cache
Builds on the adopted PR #213 macOS/Metal work with two fixes and tests:
- fit.py: always drop MLX-quantized models. Odysseus only generates serve
commands for llama.cpp/Ollama (Metal) and vLLM/SGLang (CUDA); MLX needs the
mlx_lm runtime and the catalog's MLX repos ship no GGUF alternative, so they
were surfaced on Apple Silicon but could never be served.
- cookbook_routes.py (macOS branch only): `rm -rf build` before configure so a
poisoned CMakeCache from a prior failed CUDA attempt can't make every later
build fail; explicit -DCMAKE_BUILD_TYPE=Release; a clear "brew install cmake"
hint if cmake is missing. Linux/CUDA path unchanged.
- tests/test_hwfit_macos.py: MLX hidden on metal, MLX still hidden on CUDA
(regression guard), Metal detection on Apple Silicon, and skipped on
Linux/Intel (proves non-macOS detection is untouched).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* Propagate unified_memory flag and document macOS GPU/Docker caveat
- hardware.py: detect_system now carries the unified_memory flag from GPU
detection into the system dict (it was set by _detect_apple_silicon / AMD-APU
detection but dropped during result assembly, so the API always reported
null). Lets callers distinguish unified from discrete VRAM.
- README: prominent warning that Docker on Apple Silicon can't reach the Metal
GPU (runs a Linux VM) — Cookbook must run natively for GPU serving; fix stale
text that said Cookbook recommends MLX models (now hidden as unservable).
- test: detect_system propagates unified_memory.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* Put Odysseus's venv bin on PATH for cookbook runners
Native (non-Docker) installs run from a virtualenv whose bin holds the `hf` CLI
and `python3` the cookbook download/serve tmux scripts shell out to. Those
scripts start in a fresh login shell with the venv NOT activated, so on a native
macOS install `hf download` failed with "hf: command not found" — and the
`pip --user` self-heal missed because macOS has no bare `pip` command.
- cookbook_helpers.py: _local_tooling_path_export() — pure helper returning a
PATH export for the running interpreter's bin dir (escaped for double quotes).
- cookbook_routes.py: download + serve runners prepend that dir on local runs
(gated off SSH/Windows); swap the `pip` install fallbacks to `python3 -m pip`.
- tests: helper output for normal and spaced paths.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* Document macOS llama.cpp serving prerequisites
Clarify the two serving paths on Apple Silicon: the recommended zero-build
route (brew install llama.cpp ships a Metal llama-server Cookbook finds on PATH),
and the from-source fallback, which requires cmake + Xcode Command Line Tools.
Without those the build is skipped and serving silently degrades to a slow CPU
build, so new users now know to install them (or use the prebuilt) up front.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* Recommend only GGUF-servable models on Metal
Apple Silicon's only serving engines are llama.cpp and Ollama, both GGUF-only
(vLLM/SGLang are CUDA/ROCm and don't run on macOS). The catalog tags raw
safetensors repos with a default Q4_K_M quant, so the fit-ranking was
recommending ~397/501 models that have no GGUF and fail to serve on Metal with
"No GGUF found" (e.g. microsoft/Phi-mini-MoE-instruct).
Drop any model without a real GGUF (is_gguf/gguf_sources) on Apple Silicon —
subsumes the previous AWQ/GPTQ/FP8 special-case into one rule. On CUDA these
stay visible since vLLM serves safetensors directly. Metal recommendations go
501 -> 104, all actually servable.

* Remove macOS launchd LaunchAgent (cherry-picked extra)
Drop the launchd service from the PR #213 cherry-picks: the
install-service-macos.sh installer, the com.odysseus.ui.plist template, and the
README section documenting them. Tangential to the core Cookbook/Metal support
and not wanted. The build-macos-app.sh launcher is kept.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* Add one-command macOS quick start (start-macos.sh)
Running Odysseus natively on a Mac previously meant ~7 manual terminal steps
(brew deps, venv, activate, pip, setup.py, uvicorn with the right port) — not
friendly for a generic macOS user, and the native run is required because Docker
on macOS can't reach the Metal GPU.
- start-macos.sh: installs Homebrew deps (python@3.11, tmux, prebuilt Metal
llama.cpp), creates the venv, installs requirements, runs setup, and launches
on a non-AirPlay port (7860). Idempotent; re-run to start again.
- README: the Apple Silicon section now leads with this one-command quick start
and the clickable .app, with engine/port/manual details folded into a
collapsible block. Added a pointer at the top of the manual-install section.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* macOS quick start: auto-open browser when ready
The "open this URL" line scrolled out of view as uvicorn kept logging after it,
so users missed it. Now start-macos.sh waits (in the background) until the
server accepts connections, prints a boxed "ready" banner at that point (i.e.
after the startup burst, not before), and opens the URL in the default browser
automatically. Skippable with ODYSSEUS_NO_OPEN=1 for headless/SSH use.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* Don't assume/force a specific Python version on macOS
The README claimed "system Python is 3.9" — a machine-specific generalization
that's often wrong (macOS ships no recent Python by default; many users already
have 3.11+). Make it generic, and make start-macos.sh detect an existing
Python 3.11+ and use it, only installing python@3.11 when none is found instead
of forcing it on top of the user's Python.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* Align start-macos.sh venv path with build-macos-app.sh
start-macos.sh created the environment in .venv/, but build-macos-app.sh and
the manual install steps use venv/ — so the clickable .app wouldn't reuse the
quick-start's environment and would rebuild a second one. Use venv/ everywhere.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* README: state clearly that MLX is unsupported on Apple Silicon
Odysseus has no mlx_lm runtime; it serves GGUF (llama.cpp/Ollama) and CUDA
(vLLM/SGLang) only. MLX-only models can't run on a Mac and are hidden from
Cookbook — make that explicit in both the quick start and the details.

* start-macos.sh: build the venv with an arm64 Python on Apple Silicon
A clean-room run surfaced this: with a universal2/x86 Python (e.g. the
python.org installer under /usr/local), the venv's compiled extensions install
as arm64 but get loaded as x86_64 when launched from the .app bundle, so it
crashes with "incompatible architecture (have arm64, need x86_64)". The terminal
run happened to work only because a universal binary defaults to arm64 there.
On Apple Silicon, look only under /opt/homebrew (arm64-only) for the build
Python, and install Homebrew's python@3.11 if none is present — so the venv is
arm64-only and launches correctly from both the terminal and the .app. Intel
and non-mac paths are unchanged. Verified end-to-end in a clean clone: .app now
boots on Metal with no arch error.

* Address dev-exp review: macOS setup robustness + doc/UX fixes
From the voltagent dev-exp review of the branch:
- README: fix broken anchor links (the em-dash heading produced a slug the links
didn't match); simplify the heading to a stable slug.
- cookbook_routes.py: add /opt/homebrew/bin and /usr/local/bin to the serve PATH
so a brew-installed llama-server/ollama is found instead of falling back to a
slow source build.
- start-macos.sh: guard against an empty Python path; fail fast with a clear
message on port-in-use; ERR trap with a "safe to re-run" message; show pip
progress (drop --quiet on the slow requirements install); stop the background
browser-opener cleanly on exit/Ctrl+C (no orphaned poller).
- setup.py: bind hint to 127.0.0.1; suppress the manual run-hint when launched
by start-macos.sh (ODYSSEUS_SKIP_RUN_HINT) so the URL isn't contradictory.
- build-macos-app.sh: the .app only opens the browser once the server is
actually ready (not after the readiness timeout).
- cookbookServe.js: drop "Diffusers" from the Metal backend picker —
diffusion_server.py is CUDA-only, so it was an unservable option on macOS.

chat_routes.py persisted a session's "mode" in three best-effort spots —
reading the current mode, writing the effective mode, and setting
research_pending on the stream path. Each opened a session with SessionLocal()
and called .close() as the LAST statement inside a try/except, so if anything
before close() raised (e.g. a SQLite "database is locked" under concurrent chat
streams) the except only logged and the connection was never returned to the
pool.
DATABASE_URL defaults to file-backed SQLite, whose engine uses SQLAlchemy's
default QueuePool (5 connections + 10 overflow). Repeated leaks on these hot
paths exhaust the pool; later requests then block for pool_timeout and fail
with "QueuePool limit ... reached", taking the app down until restart.
Move the logic into two best-effort helpers in core.database, next to the
existing session helpers (update_session_last_accessed, get_session_by_id):
- get_session_mode(session_id) -> Optional[str]
- set_session_mode(session_id, mode) -> bool
Both route through the existing get_db_session() context manager, which commits
on success, rolls back on error, and always closes in a finally, so the
connection is returned to the pool on every path. chat_routes.py now calls
these instead of hand-rolling sessions, also removing three copies of the same
try/except.
Add tests/test_session_mode_helpers.py: the helpers commit+close on success
and, on a mid-operation DB error, swallow + roll back + close (no leak). The
error-path tests fail against the old close()-inside-try pattern.
* Fix YEARLY recurring CalDAV events only showing on DTSTART year (#170)
Recurring events with RRULE:FREQ=YEARLY only appeared in the calendar
on the year matching DTSTART, not in subsequent years. The list_events
query filtered by , which excludes
recurring events whose original dtend (e.g. 2019-07-22) falls before
the requested window (e.g. 2026).
Fix: split the query into two branches — non-recurring events still
require window overlap, but recurring events (with non-empty RRULE)
are fetched by dtstart < end_dt alone. A new helper,
_expand_rrule_occurrences(), uses dateutil.rrule to expand each
recurring event into individual occurrence dicts within the requested
date range, so YEARLY/WEEKLY/MONTHLY events render correctly across
all years.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* recurrence: compound UIDs, frontend fixes, python-dateutil req, tests
- Replace _expand_rrule_occurrences with _expand_rrule that emits stable
compound UIDs ({base_uid}::{date_or_datetime}) so the frontend can
distinguish occurrences from the same series. Non-recurring events
pass through with is_recurrence=false and series_uid=uid.
- Add _resolve_base_uid() to extract the base series UID from compound
UIDs — used by PUT/DELETE /api/calendar/events/{uid} and the
manage_calendar tool so edits/deletes always target the base row.
- Update manage_calendar tool to import and use _resolve_base_uid.
- Frontend _updateEvent / _deleteEvent: detect compound UIDs and
invalidate localStorage cache after success so stale sibling
occurrences aren't shown.
- Add python-dateutil to requirements.txt as an explicit dependency.
- Add 14 regression tests in tests/test_calendar_recurrence.py
covering _resolve_base_uid edge cases, _expand_rrule with
yearly/weekly/monthly/all-day/bad-rrule, unique UIDs, and
metadata inheritance.
- Merge upstream's cleaner SQLAlchemy or_/and_ query pattern.
* recurrence: overlapping malformed-RRULE, exclusive end, multi-day crossings
Fix three edge cases in _expand_rrule:
1. Malformed-RRULE fallback now checks window overlap. list_events
fetches recurring rows with only dtstart < end_dt, so a broken
old recurring event could appear in unrelated future windows.
Now fallback returns [] unless the base event's dtstart/dtend
actually intersect [start, end).
2. Exclusive end boundary. rule.between(start, end, inc=True) was
inclusive on end, but the route contract and non-recurring SQL
filter both use [start, end). Added occ_start >= end guard.
3. Multi-day crossings. A recurring occurrence that starts before
the window but ends inside it was missed (only occ_start was
checked). Now expands from start - duration and filters by
occ_start < end AND occ_end > start, matching non-recurring
overlap behavior.
Tests: +4 tests for these cases (18 total)

An image attachment only got through if the model name was on a short
built-in list. Anything else was treated as text-only and the image was
quietly dropped, so the model never saw it. That left out a lot of the
smaller vision models you can run locally (moondream was the one I hit).
Pulled the check into is_vision_model() in chat_helpers, broadened it to
cover those, and added a test. Models that already worked are unaffected.
Fixes#124.
