parse_markdown_to_values — the read-back path for export-pdf, the export
preview, and prepare-signed-reply — matched the bold field label with [^*]+, so
it could not match a label containing '*' (the near-universal required-field
marker: "Email *", "State *", "Signature *"). The value then stayed empty, so
the exported PDF and the signed-reply attachment came out blank for that field
with no error — a whole form of required fields could export completely empty.
Match the label non-greedily (.+?) so '*' in labels is tolerated while still
splitting at the first ':**' / '**[', which also preserves a value that itself
contains ':**'.
Adds tests/test_form_markdown_roundtrip.py (render -> parse roundtrip): asterisk
text/choice/signature labels survive (fail before, pass after); plain labels and
colon-bearing values are unaffected.

If session.initialize() or list_tools() raises after the stdio
subprocess or SSE connection is already open, the AsyncExitStack is
never closed — leaking the child process or HTTP connection. Wrap the
setup phase in try/except to aclose() the stack before re-raising.
PermissionError was not in the except tuple so an unreadable settings.json
would crash the app instead of falling back to defaults. Added alongside the
existing FileNotFoundError/JSONDecodeError/ValueError catches.
Also adds test_settings_error_paths.py covering all four failure modes:
missing file, corrupted JSON, wrong type, and permission denied.
Gemma 4 returns reasoning_content in streaming responses via
llama-server, but the model wasn't listed in _THINKING_MODEL_PATTERNS,
causing reasoning tokens to be mishandled. Add "gemma" to the pattern
list and register Gemma 4's 128K context window in KNOWN_CONTEXT_WINDOWS
so the agent loop budgets context correctly.

A native function/tool call whose `arguments` field is valid JSON but not an
object — a bare array like ["ls -la"], or a string/number/bool/null — parsed
fine in function_call_to_tool_block and then every branch called args.get(...),
raising AttributeError ('list'/'str' object has no attribute 'get'). That
propagated out of the streamed agent loop (no surrounding try/except at the
call site in stream_agent_loop) and aborted the user's entire turn. Weaker and
local models routinely emit malformed args like this.
Coerce non-dict parsed arguments to {} (mirrors the existing empty-arguments
behavior), so the tool runs with empty args instead of killing the stream.
Adds tests/test_function_call_non_object_args.py covering array/string/number/
bool/null arguments — they fail before this change and pass after.
datetime.utcnow() is deprecated in Python 3.12 and removed in 3.14.
Swap the five calls in src/cleanup_service.py for a local _utcnow()
helper returning naive UTC, matching the naive DateTime columns the
archive/delete cutoffs compare against (same approach as the
task-scheduler and core-database slices). Add a regression test
asserting the helper stays naive so the cutoff math can't hit a
naive/aware TypeError.
Part of #1116
* fix: context_compactor token helpers crash on non-string message text
* fix: _truncate_text_to_token_budget returns an empty string for non-string text, not the raw value
compute_next_run parsed scheduled_time as "HH:MM" with int(parts[0]),
int(parts[1]) and no validation, so "9", "9am", "25:00", "9:" or ":30" raised
IndexError/ValueError. The POST /tasks create route passes the user/LLM-supplied
scheduled_time before its try block (and only validates the cron field), so a
bad value surfaced as an unhandled 500 rather than the clean 400 used for other
invalid fields — and the same crash could fire inside the scheduler loop when
recomputing next_run for an already-stored bad row.
Guard the parse and fail closed (warn + return None), matching the existing
invalid-cron handling in the same function.
Adds tests/test_scheduler_scheduled_time_validation.py — malformed values return
None (fail before with IndexError/ValueError), valid HH:MM still computes.
* fix: is_public_blocked_tool crashes on a truthy non-string tool name
* fix: is_public_blocked_tool fails closed (blocks) on a malformed non-string tool name
Gemma 4 and Phi-4 multimodal are natively vision-capable but their Ollama
tags ("gemma4:12b", "phi-4", "phi4") did not match any keyword in
_VISION_MODEL_KEYWORDS. The image was silently routed to the VL fallback
path instead of being passed directly to the model — users saw the model
respond to a placeholder like "[VL model unavailable - image not analyzed]"
rather than the actual image.
Adds "gemma-4"/"gemma4" and "phi-4"/"phi4" to the keyword list, following
the existing err-toward-True policy (#124): a text-only variant being
treated as vision is the safer failure than dropping a real image.
Fixes#1274 (partial — covers the Gemma 4 + Phi-4 case; the OpenRouter/free
vision fallback path is a separate issue).
The fallback helpers (llm_call_with_fallback, llm_call_async_with_fallback,
stream_llm_with_fallback) build their candidate list as the primary target
followed by the configured fallbacks. Callers prepend the session's live
(url, model) to default_model_fallbacks, so if the user also lists their current
model among the fallbacks — a common misconfiguration — the chain re-attempts
the very route that just failed: a wasted round-trip (and, for the streaming
path, a spurious 'fallback' notice for a switch that didn't actually happen).
Add a small _dedupe_candidates() helper that filters malformed entries and drops
a later repeat of an already-seen (url, model), preserving order (first wins,
keeping its headers). Apply it in all three fallback chains.

The agent tool-RAG force-includes a keyword hint's tools whenever any of its
keywords appears in the query (word-boundary match). The email-intent hint listed
"tell", which matches a huge fraction of requests — e.g. "visit <url> and tell
me the title" — so the whole email toolset was force-included and crowded out the
relevant tools. The model then saw a prompt dominated by email tools and reported
it had no web search / could not visit the URL.
Remove "tell" from the email keyword set. Genuine email intent still fires on
email/mail/gmail/inbox/unread/message/send/reply.
Test drives get_tools_for_query directly with retrieval stubbed (the keyword
hints are deterministic, no embeddings needed): a "...tell me..." web query no
longer pulls in email tools, a real email request still does.

VectorRAG.search() filters with ChromaDB where={"owner": owner}, returning only
documents whose owner equals the requesting user. The keyword fallback
(_keyword_search_fallback, used when the primary query raises) guarded with
`if doc_owner and doc_owner != owner: continue`, so a document with a
missing/empty owner fell through and was returned to whichever user issued the
query — a cross-user information leak on the fallback path.
Match the primary path's strict filter: skip any doc whose owner != the
requested owner, including owner-less docs.

lstrip("\n[PDF content]:") treats the argument as a character set,
not a prefix, so it chews into the following [Page N text]: marker —
e.g. turning [Page 1 text]: into "age 1 text]:". The correct helper
strip_pdf_content_marker (which uses removeprefix) already exists in
the same file and is used by other call sites.
Fixes#1663

Removing one RAG directory destroyed the whole shared ChromaDB collection
(all owners + base index) instead of just that directory's chunks. Shared
root cause: PersonalDocsManager.remove_directory called rebuild_index()
(delete_collection + recreate) then re-indexed only the remaining tracked
dirs (ownerless, never personal_dir). The targeted VectorRAG.remove_directory
that should have been used was itself broken (where={"source":{"$contains":dir}}
selects nothing on scalar metadata and would over-delete siblings), and the
dead do_manage_rag path fired a second unconditional rebuild.
- VectorRAG.remove_directory: select chunks in Python by a path-boundary match
on the stored absolute `source` (dir or dir+os.sep), abspath-normalized.
Keys on `source` (always written), never `owner` -- no migration.
- PersonalDocsManager.remove_directory: call the targeted remove instead of
rebuild_index() + partial reindex.
- do_manage_rag (dead code): drop the second rebuild_index() (hygiene).
- rag_server.py add path: abspath so indexed `source` matches the remove.
No schema change. Prevents future wipes (does not recover already-wiped
vectors). Adds hermetic regression tests at three layers.

Anthropic's Messages API rejects temperature > 1.0 with HTTP 400, but
_build_anthropic_payload forwarded it verbatim. The shipped "Nietzsche" preset
uses temperature 1.2 and the UI slider allows up to 2.0, so every Claude request
under such a preset hard-broke. Clamp into [0.0, 1.0] in the Anthropic builder
only (OpenAI keeps its wider 0.0-2.0 range). Covers all three Anthropic call
paths, which build through this one function. None is passed through unchanged.

context_compactor.maybe_compact built its summary text with
msg.get('content', '')[:2000], which raised
TypeError: 'NoneType' object is not subscriptable on assistant turns
whose content is None (turns that carried only native tool_calls).
Once a conversation crossed the 85% compaction threshold — reached
after only a few turns on small-context local models plus the large
agent prompt — every subsequent message failed ("send more than three
messages and it stops working").
Flatten message content to text first via a _content_as_text helper
(str passthrough, multimodal list blocks joined, None -> "") and
tolerate a missing role. Adds tests/test_context_compactor.py covering
the helper and a >=4-message conversation that forces compaction with
a None-content tool-call turn (fails before this change, passes after).
