From: Kenny Van de Maele Date: Thu, 4 Jun 2026 17:56:15 +0200 Subject: [PATCH 08/66] fix: live-resume chat stream on session re-entry (#2539) (#2561) * fix: live-resume chat stream on session re-entry (#2539) When a session was re-entered after a page refresh or in a new tab while its agent run was still streaming, the UI showed a frozen "Generating response..." spinner, polled stream_status until the run finished, and then did a full reload. The live tokens were never shown. Add resumeStream() in chat.js: it consumes GET /api/chat/resume/{id} (which replays the run's buffer then streams live), renders reply tokens as they arrive, and reloads the session on completion for the canonical final render. sessions.js _checkServerStream now calls it on re-entry and falls back to the previous spinner+poll path if it is unavailable. * Finalize plain-text resume in place instead of reloading On stream completion, resumeStream() called selectSession(), forcing a full history re-fetch and a visible flicker right as the stream finished. For plain text replies (no tool calls, sources, doc streaming, or multi-round output) the live tokens are already rendered, so finalize in place: replace the live bubble with a canonical single message via chatRenderer.addMessage (markdown + footer actions + metrics, the same renderer history uses), captured from the streamed metrics event. No history refetch, no extra round-trip, no flicker. Rich responses still reload, since their canonical render (tool bubbles, sources, multi-bubble) is rebuilt from the saved DB record. * Use a dedicated set for the resume re-attach lock; fix stale docblock resumeStream() marked its re-attach lock in _backgroundStreams, which checkBackgroundStream() also reads. On a second re-entry of the same session while a resume was still live, checkBackgroundStream() mistook that entry for a same-tab POST stream and spawned its own spinner+poll bubble. Move the lock to a dedicated _resumingStreams set (also covered by hasActiveStream) so the two paths no longer collide. Also update the resumeStream docblock to describe the in-place finalize vs reload split. --- static/js/chat.js | 151 +++++++++++++++++++++++++++++++++++++++++- static/js/sessions.js | 9 ++- 2 files changed, 158 insertions(+), 2 deletions(-) diff --git a/static/js/chat.js b/static/js/chat.js index dd47188..ee347b9 100644 --- a/static/js/chat.js +++ b/static/js/chat.js @@ -82,13 +82,15 @@ import createResearchSynapse from './researchSynapse.js'; // Background streaming support const _backgroundStreams = new Map(); // sessionId -> { status, accumulated, sourcesHtml, abortCtrl, query, metrics } + const _resumingStreams = new Set(); // sessionId -> a resumeStream() reader is live (re-attach lock) let _streamSessionId = null; // Session ID for the currently active reader loop let _lastReaderActivity = 0; // Timestamp of last reader.read() success — used to detect frozen streams let _webLockRelease = null; // Function to release the Web Lock held during streaming /** Check if an SSE reader is still actively connected for a session. */ function hasActiveStream(sessionId) { - return _streamSessionId === sessionId || _backgroundStreams.has(sessionId); + return _streamSessionId === sessionId || _backgroundStreams.has(sessionId) || + _resumingStreams.has(sessionId); } // Sources box builder and toggleSources are now in chatRenderer.js @@ -3045,6 +3047,152 @@ import createResearchSynapse from './researchSynapse.js'; var _notifyStreamComplete = chatStream.notifyStreamComplete; var _insertStreamDoneToast = chatStream.insertStreamDoneToast; + /** + * Live-resume a chat run still streaming detached on the server (#2539). + * + * On session re-entry, GET /api/chat/resume/{id} replays the run's buffer then + * streams live; reply tokens render as they arrive.

Convert it to a sys.modules alias of the canonical services module (matching src/search/core.py, providers.py, ranking.py) so the two cannot drift, and add an identity assertion to test_search_module_consolidation.py. content.py and query.py are intentionally left as-is: the copies have drifted and services lacks fixes that src has, so they need services reconciled first before they can be shimmed safely. * chore: dedupe src/search content.py and query.py into shims Convert src/search/content.py and query.py to sys.modules aliases of the canonical services/search/* (matching cache.py, core.py, providers.py, ranking.py) so the duplicate copies cannot drift. Repoint the two tests that were coupled to the src-copy internals onto the canonical services surface (behaviour is equivalent): - test_src_search_query_nonstring.py: import services.search.query instead of loading the src file by path. - test_security_regressions.py::test_web_fetch_guard_blocks_redirect_into_private: mock httpx.get (services uses the module-level get, not httpx.Client) and assert on the canonical 'Blocked' message. Drop the now-redundant [src_content, service_content] parametrization in test_search_content_extraction_parity.py and test_search_content_url_guards.py (after the shim both params are the same object); add content/query identity assertions to test_search_module_consolidation.py. --- src/search/cache.py | 60 +-- src/search/content.py | 422 +----------------- src/search/query.py | 144 +----- .../test_search_content_extraction_parity.py | 5 +- tests/test_search_content_url_guards.py | 7 +- tests/test_search_module_consolidation.py | 7 + tests/test_security_regressions.py | 11 +- tests/test_src_search_query_nonstring.py | 28 +- 8 files changed, 44 insertions(+), 640 deletions(-) diff --git a/src/search/cache.py b/src/search/cache.py index 11fe722..e66aaff 100644 --- a/src/search/cache.py +++ b/src/search/cache.py @@ -1,57 +1,11 @@ -"""Search and content caching with LRU eviction.""" +"""Compatibility wrapper for the canonical services.search.cache module. -import hashlib -import logging -from datetime import datetime, timedelta -from pathlib import Path -from typing import Dict +``src.search.cache`` stays importable for older agent/deep-research code, but the +implementation now lives in ``services.search.cache`` so the two cannot drift. +""" -logger = logging.getLogger(__name__) +import sys -# Cache directories -CACHE_DIR = Path(__file__).resolve().parent.parent / "cache" -SEARCH_CACHE_DIR = CACHE_DIR / "search" -CONTENT_CACHE_DIR = CACHE_DIR / "content" -CACHE_MAX_ENTRIES = 1000 +from services.search import cache as _cache -# Create cache directories -SEARCH_CACHE_DIR.mkdir(parents=True, exist_ok=True) -CONTENT_CACHE_DIR.mkdir(parents=True, exist_ok=True) -

Subject: [PATCH 10/66] Show the serving provider in the model-info card
 (#2185)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Show the serving provider in the model-info card

The model-info popup (click the model name on a message) shows the model
and pricing, with a logo inferred from the model NAME. But the same model
can be served by different endpoints — e.g. claude-haiku via OpenRouter
vs GitHub Copilot vs Anthropic direct — which the name-based logo can't
distinguish.

Add a 'Provider' line derived from the session's endpoint URL:
- new providerLabel(endpointUrl) in static/js/providers.js maps the host
  to a friendly name (GitHub Copilot, OpenRouter, Anthropic, OpenAI,
  Google, AWS Bedrock, DeepSeek, Mistral, Groq, Together, Fireworks,
  Perplexity, xAI), 'Local' for loopback/LAN, else the bare host.
- static/js/chatRenderer.js renders it under Model in the card, from
  window.sessionModule.getCurrentEndpointUrl().

* Anchor provider-label patterns to the hostname

providerLabel matched its patterns against the full endpoint URL with
unanchored substrings, so a host like max.airlines.com matched /x\.ai/ and was
mislabeled "xAI". Anchor each pattern to the end of the hostname ((^|.)domain$)
and test against the parsed host instead of the raw URL.

Subject: [PATCH 11/66] feat: Add edit_file tool + file-change diffs (#1239)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Add edit_file tool + file-change diffs

edit_file is an exact old_string -> new_string replacement on a file on disk
(fails if old_string is missing or non-unique unless replace_all); write_file
also returns a unified diff. Diffs render collapsed in the tool bubble
(filename + +adds/-dels, theme colors); the raw JSON command box is hidden.

Security: edit_file is a sensitive filesystem-write tool, treated everywhere
write_file is —
  - added to NON_ADMIN_BLOCKED_TOOLS (is_public_blocked_tool / blocked_tools_for_owner),
    so on auth-enabled deployments a non-admin cannot run it; execute_tool_block
    refuses it for non-admin owners.
  - confined by the same path policy as read_file/write_file (allowlist +
    sensitive-file deny) via _resolve_tool_path.

Disambiguation in tool descriptions + bash prompt: edit_file/write_file are the
only way to write files (they show a diff) — never edit_document (editor panel)
or a bash heredoc/redirect.

Tests (tests/test_edit_file.py): non-admin block (policy + execution gate),
successful edit, not-found old_string, non-unique old_string (+ replace_all),
and path outside the allowed roots.

Files: src/tool_execution.py, src/agent_loop.py, src/tool_schemas.py,
src/agent_tools.py, src/tool_index.py, static/js/chat.js, static/style.css,
tests/test_edit_file.py.

* Drop redundant import os in write_file closure

os is already imported at module top.

+NEVER use bash to create or change files — no `>`/`>>` redirects, no heredocs (`cat > f << 'EOF'`), no `tee`, `sed -i`, `awk -i`, no `python -c` that writes. To CREATE or fully rewrite a file use `write_file`; to change part of an existing file use `edit_file`. Those show a diff and are the ONLY allowed way to write files. (bash is for read-only inspection: `ls`, `cat` to READ, `grep`, `git status`/`git diff`, builds, installs.)

Subject: [PATCH 12/66] feat: add code-navigation tools (grep, glob, ls) +
 read_file line ranges (#1670)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Gives the agent first-class code navigation instead of shelling out via bash
(token-heavy, unreliable on weaker models, unstructured). Mirrors the
Grep/Glob/Read primitives that Claude Code / opencode expose.

- grep: regex search over file contents across a tree. Uses ripgrep when
  available (with explicit excludes so junk dirs are skipped even without a
  .gitignore); falls back to a pure-Python walk+regex when rg is absent.
  Returns file:line:match, capped.
- glob: find files by glob pattern (recursive), newest first.
- ls: list a directory (folders first, then files with sizes).
- read_file: optional offset/limit for line-range reads of large files
  (plain-path calls stay back-compatible).

All confined by the same path policy as read_file (_resolve_tool_path:
data/tmp allowlist + sensitive-file deny). Junk dirs (.git, node_modules,
venv, __pycache__, dist/build, …) skipped. Output capped (200 hits,
400 chars/line). Admin-gated like the other filesystem tools.

Wiring: schemas + native arg->content serializer (src/tool_schemas.py), tool
tags (src/agent_tools.py), always-available + descriptions (src/tool_index.py),
admin gate (src/tool_security.py), dispatch + impls (src/tool_execution.py).

Tests: tests/test_code_nav_tools.py — match/skip-junk/ignore-case/glob-filter,
allowlist rejection, glob/ls, read-range, and the no-ripgrep Python fallback.

Subject: [PATCH 18/66] fix(models): make pinned models visible in chat UI
 (#2481)

Two bugs prevented pinned models from appearing in the chat model picker:

1. _fetch_models() only used _cached_model_ids(), ignoring pinned_models.
   Since Fireworks AI doesn't list kimi-k2p6-turbo in /v1/models, the
   cached list was empty, so the endpoint showed as offline with no models.

2. _curate_models() filtered unknown pinned IDs into models_extra, but the
   chat UI only reads models (primary list). Pinned models stayed invisible.

Fix: use _visible_models() to merge cached + pinned, then promote pinned
IDs from models_extra to models so they appear in the dropdown.

Closes #1521 follow-up

Subject: [PATCH 21/66] fix: llm_call_async does not retry on HTTP
 429/502/503/504 (#2364)

The retry loop raised immediately for any non-success HTTP response
regardless of attempt count. For transient upstream errors (rate limit,
bad gateway, gateway timeout) the function should back off and retry
within the existing attempt budget.

Also lets ConnectError / ConnectTimeout retry when the host has not been
cooled and attempts remain, instead of always raising on the first
connect failure.

Subject: [PATCH 22/66] fix: KeyError on missing 'content' key in system
 messages (#2362)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A system message that arrives without a 'content' key — possible via
malformed tool results — raised a KeyError in the hot path of llm_call,
llm_call_async, and stream_llm. Replace m["content"] with
m.get("content") or "" in all three functions so a missing key degrades
to an empty string instead of crashing.

Also removes a redundant .rstrip() after .strip() in _model_activity_key.

Subject: [PATCH 24/66] fix: bool('false') is True coerces endpoint toggles
 incorrectly (#2361)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python's bool('false') returns True because the string is non-empty.
A JS client serialising a boolean as the string 'false' would have
supports_tools or is_enabled silently flipped to True — so 'disable
tool support' would actually enable it.

Use an explicit lookup dict for supports_tools and a case-insensitive
string check for is_enabled so both string and native bool inputs are
handled correctly.

Subject: [PATCH 26/66] fix(hwfit): filter non-GGUF models on Windows (#2530)

Odysseus only supports llama.cpp on Windows (vLLM/SGLang are
explicitly blocked). llama.cpp requires GGUF, so AWQ/GPTQ/FP8
safetensors models without a GGUF alternate should not be
recommended in the Cookbook on Windows hosts.

Changes:
- hardware.py: add 'platform': 'windows' to _detect_windows()
  so downstream logic can identify Windows hosts.
- fit.py: include is_windows in the existing GGUF-only filter
  alongside apple_silicon and consumer_amd.
- tests: add test_hwfit_windows.py with regression tests.

Fixes #122, #614 (root cause: unservable models recommended).

Subject: [PATCH 27/66] fix(agent): default bash/python cwd to data/ to prevent
 ephemeral file loss (#2586)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Agent subprocesses (bash, python) previously inherited the container's default
working directory (/app), so files created with relative paths landed in the
ephemeral container layer and were silently destroyed on any docker compose up
--build or container recreation.

Set cwd=_AGENT_WORKDIR (resolved to <repo_root>/data at import time) and
HOME=_AGENT_WORKDIR on both subprocess launchers so that:
- pwd inside a bash tool returns the persistent data directory
- relative paths and ~ resolve to a location that survives rebuilds
- the agent can still cd to any absolute path it needs

The resolution uses pathlib.Path(__file__).parent.parent / "data", which
works for both Docker (/app/src → /app/data) and manual installs
(<repo>/src → <repo>/data) without requiring a new env var or compose change.

Fixes #2512

Subject: [PATCH 29/66] fix(llm): auto-detect <think> in content stream for
 unregistered thinking models (#2588)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(llm): auto-detect <think> in content stream for unregistered thinking models

_THINKING_MODEL_PATTERNS only covers known model families by name. Qwen3-derived
models with non-standard names (e.g. Qwopus, custom QwQ forks) are not matched,
so their <think>...</think> content streams through as visible chat text instead
of being routed to the thinking display.

When the first content delta opens with <think> and the model was not already
identified as a thinking model, dynamically flag the stream as a thinking model
for the remainder of the response. This enables the existing </think> repair path
(line below) and ensures the frontend receives the full <think>...</think> wrapper
it needs to split thinking from the final answer.

The check is restricted to the very first content delta (_first_content_sent is
False) to avoid misidentifying models that happen to write "<think>" mid-answer.

Fixes #2225

* fix(llm): replace inert _thinking_model flag with _in_think_tag state machine

The original auto-detect set _thinking_model=True on the first <think> chunk
but still emitted it as a regular delta and set _first_content_sent=True
immediately, so no subsequent chunk could enter the repair path.

Replace with _in_think_tag bool: enter thinking mode when first content starts
with <think>, route all chunks to the thinking channel until </think> is found,
then the tail becomes the first regular delta. Adds three regression tests.

* fix(llm): replace _first_content_sent guard with _think_open_stripped

Opening-tag stripping used `not _first_content_sent` as the guard, but
_first_content_sent stays False throughout the entire think block (it only
flips when regular content is emitted). So `find(">")` ran on every
reasoning chunk — not just the first — and silently truncated everything
before the first ">" in any reasoning text containing comparisons, arrows,
or code.

Fix: add `_think_open_stripped = False` alongside `_in_think_tag`. Use it
as the strip guard in both the "still inside <think>" path and the
"</think> found in same chunk" split path. Set it True once the opening
tag is consumed so all subsequent chunks reach the thinking channel
unmolested.

Add regression test: 3-chunk stream where the middle chunk contains
"c > d" — confirms "more c " is not dropped.

Subject: [PATCH 32/66] fix: renaming a user leaves their API tokens resolving
 to the old owner (#1932)

* fix: renaming a user leaves their API tokens resolving to the old owner

* Drive rename token-cache test through the real auth resolver instead of patching a closure

      How it actually started
      
-      
      Odysseus is everything I hate, just making it tolerable.
      
-      
      
-        I started working on the Odysseus project because running local AI felt fun — a step into the future.
-        But the options to actually engage with LLMs felt like taking steps back. Where were
-        features like Memory, Deep Research, Agents, and just basic integrations?!
-      
      
-      
      
-        So I started building my own, for fun — and eventually figured it might be fun to
-        share what I built for myself with others. Doesn't work for you? Well… it runs
-        great on my hardware.

      Get started
      
-        
      Clone it and run
      
-        
      It's open source and free. No sales team, no demo request — just clone the repo.

Subject: [PATCH 41/66] feat(provider): add GitHub Copilot provider with
 device-flow auth (#1480)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat(provider): add GitHub Copilot provider with device-flow auth

Adds GitHub Copilot as a model provider, so Copilot models (gpt-4o/4.1/5,
Claude, Gemini, …) work through the normal chat + agent loop, incl. native
tool calling and vision.

Auth is one-click via the GitHub OAuth device flow; the access token is stored
as the endpoint's (encrypted) api_key and sent directly as `Authorization:
Bearer` (no Copilot-token exchange, no refresh — matching how editors talk to
the Copilot API). Copilot is a normal ModelEndpoint detected by host; the only
provider-specific behaviour is a small set of required request headers,
injected centrally.

Sign-in is available from Settings → model endpoints ("Connect GitHub
Copilot") and from chat via `/setup copilot`.

- src/copilot.py (new), routes/copilot_routes.py (new): constants, header
  builders, device-flow start/poll, model discovery, owner-scoped endpoint
  provisioning.
- src/llm_core.py, src/endpoint_resolver.py: detect `copilot`, inject headers,
  per-request x-initiator/vision.
- src/agent_loop.py: allowlist api.githubcopilot.com for native tool schemas.
- src/model_context.py: known context windows for Copilot (no unauthenticated
  /models probe).
- static/, README, tests/test_copilot*.py.

* Tidy copilot_routes: clarify supports_tools, note _PENDING is per-process

+"""GitHub Copilot device-flow login.
+
+Drives the GitHub OAuth *device flow* and, on success, creates (or refreshes)
+an owner-scoped ``ModelEndpoint`` pointing at the Copilot API with the
+device-flow access token stored as its (encrypted) ``api_key``. After that the
+endpoint behaves like any other OpenAI-compatible provider — the Copilot-
+specific request headers are injected centrally by ``build_headers`` /
+``_provider_headers`` (see :mod:`src.copilot`).
+
+Flow:
+  1. ``POST /api/copilot/device/start`` → returns a ``poll_id`` plus the
+     ``user_code`` + ``verification_uri`` to show the user. The secret
+     ``device_code`` is kept server-side, never sent to the browser.
+  2. The browser polls ``POST /api/copilot/device/poll`` with ``poll_id``.
+     While pending it returns ``{status: "pending"}``; once the user authorises
+     it provisions the endpoint and returns ``{status: "authorized", ...}``.
+
+All routes are admin-gated (endpoint/provider management is an admin action).

+"""GitHub Copilot provider support.
+
+Copilot exposes an OpenAI-compatible API at ``https://api.githubcopilot.com``
+(``/chat/completions`` + ``/models``). Authentication is a GitHub OAuth
+**device flow**: the user authorises a device code in their browser and we
+receive a long-lived ``access_token`` that is sent directly as
+``Authorization: Bearer `` — there is no separate Copilot-token
+exchange and no refresh (mirrors how editors / opencode talk to Copilot).
+
+The only provider-specific wrinkle beyond the bearer token is a handful of
+required request headers (API version, intent, an editor-style User-Agent,
+and ``x-initiator`` for agent-vs-user request accounting). Those live in
+:func:`copilot_headers`.
+
+This module holds the constants + pure helpers; the HTTP device-flow calls
+live in :mod:`routes.copilot_routes` so they can be auth-gated.

Subject: [PATCH 42/66] fix(docker): opt-in INSTALL_OPTIONAL build arg for AGPL
 extras (#2633)

Default image installs requirements.txt only. Set INSTALL_OPTIONAL=true
at build time to add requirements-optional.txt (PyMuPDF, markitdown, etc.)
without baking AGPL into the standard distributed image.

Subject: [PATCH 43/66] Fix truncate_messages persisting an inflated
 message_count (#2052)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

truncate_messages deletes db_messages[keep_count:] (a no-op when
keep_count >= the real message total) then unconditionally wrote
db_session.message_count = keep_count. When keep_count exceeds the
number of messages that actually exist — e.g. the manage_session AI
tool defaults keep_count to 10, and the HTTP truncate endpoint passes
any client value — the persisted count is set too high (10 on a
3-message session), diverging from the real row count. That column
gates lazy DB-hydration in get_session (message_count > 0) and is
surfaced to the history UI, so it is correctness-relevant. Clamp to
min(keep_count, len(db_messages)); the in-memory slice already caps
naturally.

Subject: [PATCH 44/66] fix: exclude slash-command/setup messages from LLM
 context (#2634) (#2640)

Slash-command replies and the echoed /setup command are persisted to session
history so they render in the transcript, but they are UI chatter the user
never meant as conversation. They were sent to the model on the next turn,
which then commented on '/setup ...' and exposed transient values (e.g. the
Copilot device user_code) to the LLM.

- get_context_messages() (the LLM-API view) now skips messages tagged
  metadata.source == 'slash'. Display/history-load paths use raw history and
  are unaffected.
- slashCommands.js tags the echoed user command with source:'slash' too (the
  assistant replies already carried it); the user line was the one untagged
  path that still reached context.

Fixes #2634.

Subject: [PATCH 46/66] fix(tests): isolate session route import stubs

Keeps src.request_models real and restores both sys.modules and parent routes.session_routes package attributes after temporary test stubs. Restores one focused part of the Python CI baseline tracked in #2580.

Subject: [PATCH 47/66] fix(tests): restore src.database after webhook import

Restores both sys.modules and parent src.database package state after the webhook SSRF tests import src.webhook_manager against the real database module. Fixes one focused #2580 CI-baseline pollution bucket.

* feat: round-limit handling — Continue affordance at the cap + configurable cap

When the agent loop runs out of rounds (per-message step cap, default 20)
while still actively using tools, it stopped silently mid-task. Now:

1. The loop emits a `rounds_exhausted` SSE event at the cap, and the UI shows
   a "Continue" pill at the bottom of the chat that resumes the task from where
   it left off. Repeated cap-hits each get a fresh Continue (multiple continues
   in a row).
2. The cap is configurable in Settings → Agent ("Max steps per message"),
   validated on the client, at the save endpoint, and at the read site.

- src/agent_loop.py: track `_exhausted_rounds` (set only when a full
  tool-executing round completes on the last allowed round — i.e. the agent
  wanted to keep going); emit `{"type":"rounds_exhausted","rounds":N}` (logged).
- routes/chat_routes.py: read `agent_max_rounds` (clamped 1..200), pass as
  `max_rounds`; forward the new event through the SSE relay.
- routes/auth_routes.py: validate numeric settings on save (int + clamp;
  agent_max_rounds 1..200, agent_max_tool_calls 0..1000; 400 on non-int).
- src/settings.py: default `agent_max_rounds = 20`.
- static/: Settings input + client-side clamp; the Continue pill (reuses the
  existing .stopped-indicator / .continue-btn classes and theme vars
  --border/--fg/--bg/--accent); appended to the chat container so it survives
  the message re-render at stream finalize. chat.js cache version bumped.

* test: cover rounds_exhausted emission (cap-hit vs normal finish)

Drives the real stream_agent_loop with mocked LLM stream / tool exec / settings:
a tool block every round exhausts the cap and must emit rounds_exhausted; a
plain answer hits the done-break and must not. Guards the for/else logic.

Subject: [PATCH 51/66] Make write_file/edit_file always-available like
 read_file (#2684)

read_file/grep/glob/ls are in ALWAYS_AVAILABLE but the on-disk write tools
(write_file, edit_file) were only surfaced via per-query tool-RAG retrieval.
On a bare 'edit X' request the retriever could miss them, so the model was
never offered edit_file/write_file and wrongly fell back to edit_document
(editor panel) or improvised with bash sed. Add both to ALWAYS_AVAILABLE
next to read_file; they stay admin-gated by tool_security so non-admin
exposure is unchanged.

Fixes #2683

Subject: [PATCH 52/66] feat: Add workspace: confine agent tools to a folder
 (#1103)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat: Add workspace: confine agent tools to a folder

Pick a server folder as the agent's workspace so its file/shell tools work
there and don't touch files outside it. File tools are hard-confined; bash/
python run with cwd set to the folder.

Includes a slash command: `/workspace` (alias `/ws`) — show / `set ` /
`clear` / `pick` (open the directory browser).

- routes/workspace_routes.py: GET /api/workspace/browse (admin-only).
- src/tool_execution.py: hard path confinement for read_file/write_file;
  bash/python cwd. Threaded route → stream_agent_loop → execute_tool_block.
- src/agent_loop.py: workspace note prepended to the system prompt.
- static/: overflow menu item, input-bar pill, directory-browser modal, and
  the /workspace slash command.
- tests/test_workspace_confine.py.

* Wire workspace confinement into tools that landed after this PR

edit_file (#1239) and grep/glob/ls (#1670) merged after workspace-confine was
written, so they bypassed the workspace boundary. Thread the workspace through:
  - edit_file: _do_edit_file resolves via _resolve_tool_path_in_workspace
  - grep/glob/ls: _resolve_search_root confines to the workspace (root + paths)
  - bash/python/bg cwd: workspace or _AGENT_WORKDIR (keep the #2586 data-dir
    default when no workspace is set)
Tests cover edit_file + grep/ls confinement (inside ok, outside rejected).

* Workspace picker: editable path bar + modal style cohesion + cross-platform hardening

- Make the current-folder strip an editable address bar: type/paste a full
  path and press Enter to navigate (also reaches other Windows drives and
  hidden dirs the up-only browser cannot).
- Reuse shared modal CSS: drop bespoke .workspace-modal-content/.workspace-btn*
  in favour of base .modal-content/.modal-body and the .confirm-btn button
  family; separators/hover use var(--border). Net -31 CSS lines.
- Fix the path field overflowing the modal right edge (flex stretch + margin
  vs an overflow:auto scrollbar-feedback loop): full-bleed, no h-margin.
- Cross-platform confinement: normcase the workspace commonpath check so
  containment holds on case-insensitive filesystems (Windows/macOS).
- Make tests OS-portable: sibling temp dirs instead of /etc, python os.getcwd()
  instead of pwd. 5 pass.

Subject: [PATCH 54/66] fix(tests): call live tool_execution module in
 edit-file gate test

Calls execute_tool_block through the live src.tool_execution module in the edit-file admin-gate test so the monkeypatched _owner_is_admin seam and the called function belong to the same module object. Fixes the scoped #2580 CI-order edit-file failure. Remaining Python failure is the unrelated cookbook fallback-chain environment test.

Subject: [PATCH 55/66] fix(tests): make cookbook venv fallback test
 deterministic

Makes the cookbook venv fallback-chain test deterministic by simulating the inside-venv shell state directly instead of depending on the GitHub runner Python environment. Final focused #2580 CI-baseline cleanup.

Subject: [PATCH 56/66] Fix auto-memory vector dedup dropping a user's fact on
 cross-tenant match
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

extract_and_store dedups each extracted fact against the vector store
before the (owner-scoped) text fallback. The vector store is a single
shared ChromaDB collection storing only {"source": "memory"} — no
owner — and find_similar queries it with no owner filter, so it can
return a memory_id belonging to a different tenant. The old code
continue'd (skipped storing) on any vector hit without checking
ownership, so when ChromaDB is healthy (the common path) a user's
freshly-extracted fact was silently dropped because it was merely
semantically similar to another user's memory — the text fallback that
IS owner-scoped never ran. Gate the skip on the matched memory being
this user's own (or legacy unowned), mirroring the text dedup predicate;
cross-tenant or stale matches fall through. Same bug class as #1743.

Subject: [PATCH 60/66] Render emoji shortcodes as icons in chat (#345) (#629)

Chat models often emit GitHub/Slack-style :shortcode: text (e.g. :blush:,
:microphone:) instead of the actual emoji. The renderer only converted real
Unicode emoji to the monochrome line icons, so shortcodes rendered as literal
text.

Add a pure, browser-free shortcode->Unicode map (emojiShortcodes.js) and run it
inside svgifyEmoji ahead of the existing Unicode->SVG pass, skipping /
      so code stays literal. Covers ~430 common shortcodes plus common aliases
(+1/thumbsup, etc.).

Keep the conversion from touching anything it shouldn't:
* Scope it to chat. mdToHtml/svgifyEmoji take a { shortcodes } option (default
  on); document and email body rendering (compose, export, preview) pass it as
  false so author-typed :shortcode: text stays literal. The Unicode->SVG pass
  still runs there exactly as before.
* Only convert a :shortcode: that stands on its own. A word-boundary guard
  leaves embedded colon runs alone, so "1:100:2", "10:30:45", "16:9" and
  host:fire:port are never rewritten.

Tests: extend the node-driven unit test with the boundary/false-positive cases,
and fix the markdown-rendering test loader to resolve the new emojiShortcodes
import.

+// Emoji shortcode → Unicode conversion (issue #345).
+//
+// Chat models frequently emit GitHub/Slack-style `:shortcode:` text — e.g.
+// `:blush:`, `:fire:`, `:microphone:` — instead of the actual emoji character.
+// Nothing in the render pipeline used to translate these, so they showed up as

+// This module turns the common shortcode set into the real Unicode emoji. The

+// same theme-tinted single-color line icon as any other emoji (project rule:
+// never colorful emoji), not as a colored system glyph.
+//
+// Pure and browser-free on purpose: no DOM, no imports, so it can be unit
+// tested with plain `node` (see tests/test_emoji_shortcodes_js.py).
+
+// Canonical map of common shortcode → Unicode emoji. Names follow the GitHub
+// convention (lowercase, underscore-separated). A handful of well-known aliases
+// (`+1`, `thumbsup`, `grinning_face`, …) point at the same glyph so the most

Subject: [PATCH 61/66] feat(mcp): add Streamable HTTP transport with OAuth 2.0
 (#1033)

* feat(mcp): add Streamable HTTP transport with OAuth 2.0

  Odysseus could only reach MCP servers over stdio and SSE, so modern
  remote servers like https://mcp.higgsfield.ai/mcp (Streamable HTTP,
  gated behind OAuth) could not be connected.

  Add an `http` transport that connects via the SDK's
  streamablehttp_client and authenticates with the SDK's
  OAuthClientProvider: RFC 9728 protected-resource discovery, RFC 8414
  authorization-server metadata, Dynamic Client Registration,
  authorization-code + PKCE, and token refresh. A small bridge
  (src/mcp_oauth.py) connects the SDK's blocking callback to the existing
  web callback route via an asyncio.Future keyed by the OAuth `state`,
  and the dynamic client registration plus tokens persist per-server in a
  new encrypted `oauth_tokens` column.

  The connect runs as a bounded background task so the "Add server"
  request returns immediately; redirect_handler publishes needs_auth +
  auth_url to connection state as soon as discovery/DCR completes (which
  can exceed the bounded wait), and the UI polls until connected. Remote
  users finish via the existing paste-back flow. The Google OAuth path is
  left unchanged.

  - core/database.py: encrypted oauth_tokens column + migration
  - src/mcp_oauth.py: OAuth provider, DB-backed TokenStorage, state registry
  - src/mcp_manager.py: http dispatch, background connect, _connect_http
  - routes/mcp_routes.py: http validation, needs_auth/auth_url, callback bridge
  - static/js/settings.js: Streamable HTTP option + OAuth flow with polling
  - tests: 5 new unit tests (transport dispatch, registry, token storage)

  Verified against the live Higgsfield server: discovery, DCR (client_id
  issued), loopback redirect accepted, and a PKCE authorization URL with
  needs_auth status. No regressions (full suite delta is only the 5 added
  passing tests).

* fix(mcp): address PR #1033 review feedback

  - mcp_oauth: derive redirect URI from OAUTH_REDIRECT_BASE_URL/APP_PUBLIC_URL
    (default http://localhost:7000) instead of hardcoding the port
  - mcp_oauth: leave OAuth scope unset so the SDK derives it from the server's
    WWW-Authenticate/protected-resource metadata; hardcoding an OIDC scope broke
    non-OpenID MCP servers (verified: Higgsfield still gets its server-derived
    scope)
  - mcp_oauth: prune abandoned OAuth flows (_prune_stale + _pending_ts) so the
    module-level registries can't grow unbounded
  - mcp_oauth: persist tokens/client-info in a single DB session/commit
    (_update) instead of a load+save double round-trip
  - mcp_manager: cancel and drop the background connect task in
    disconnect_server so a deleted server stops publishing status
  - database: document why the oauth_tokens migration uses TEXT while the model
    declares EncryptedText (encryption is applied at the Python layer)
  - settings.js: surface persistent OAuth-poll failures and an explicit timeout
    message instead of silently swallowing errors
  - tests: cover the stale-flow pruning

* static/js/settings.js now shows an in-flight loading state on the buttons that fire requests:

Subject: [PATCH 62/66] fix(caldav): don't prune locally-created events on sync
 (#2706)

The CalDAV pull prunes events in the synced calendar+window whose UID the
server didn't just return, to propagate upstream deletions. But CalendarEvent
had no field distinguishing a server-pulled row from a locally-created one, so
the prune also deleted events that were never on the server: events created by
the agent / email triage (which never write back to the server) and UI events
whose best-effort write-back failed. Result: silent, unrecoverable loss of the
user's appointments (hard db.delete, no soft-delete).

Add an 'origin' column to calendar_events (lightweight idempotent migration,
mirroring _migrate_add_calendar_is_utc), set origin='caldav' on rows the sync
inserts/updates, and gate the prune on origin == 'caldav'. Locally-created
events carry origin NULL and are never pruned. On the first sync after the
migration nothing is pruned (all rows NULL until re-marked), erring toward
keeping data.

Fixes #2704

Subject: [PATCH 63/66] fix(model-context): key context-window cache by
 (endpoint, model) (#2614)

get_context_length() cached the resolved context window by model id alone,
so two different remote endpoints serving the same model id (e.g. a capped
proxy at 8k vs. the full provider at 200k) collided: the first to resolve
won process-wide and the other endpoint was served the wrong window. That
silently over-trims conversations on the larger-window endpoint (it feeds
context_compactor) or overflows the smaller one (provider 400s).

Key the cache on (endpoint_url, model). Local endpoints already always
re-query, so they are unaffected.

Fixes #2603
