- SQLite dedup race: add UNIQUE(collection_name, file_hash) and switch
save_document to a plain INSERT. add_document now catches the
IntegrityError from a concurrent add of the same content, cleans up its
managed files, and returns the winning doc_id — instead of two doc_ids
for one file (each having paid for its own LLM indexing).
- PDF image paths: store the absolute path to each extracted image
instead of a path relative to the indexing process's cwd. The
 references broke as soon as a query ran from a different
directory.
- LegacyCloudAPI: URL-encode doc_id / retrieval_id path segments (added
_enc()), matching CloudBackend. An id containing '/', '?', '#' or a
space previously hit the wrong endpoint or produced a malformed URL.
Adds regression tests: UNIQUE enforcement, the add-race resolving to the
winner, absolute image paths, and encoded legacy URLs.

- legacy call_llm: open AsyncOpenAI via `async with` so the client (and
its HTTP connection pool) is closed instead of leaked.
- LocalBackend.add_document: fail fast with CollectionNotFoundError when
the collection doesn't exist, before the expensive parse + LLM index
(previously the missing FK only tripped at save time, after paying for
the LLM work). Also raise builtin FileNotFoundError for a missing path
instead of FileTypeError (which now means only "unsupported extension").
- Collection.query(doc_ids=None): the empty-collection guard now always
runs — previously it was skipped once PAGEINDEX_EXPERIMENTAL_MULTIDOC
was set. A single list_documents call serves both the guard and the
multi-doc warning (no separate call just to decide whether to warn).
- CloudBackend.query_stream: on early consumer break / GeneratorExit,
signal the background SSE thread to stop and force-close the response,
so it no longer drains the whole stream in the background.
Adds regression tests for each (client closed, fail-fast on unknown
collection, FileNotFoundError, empty-check under the multidoc env flag,
single list call, early-break thread stop).

- local delete_collection: validate the collection name before rmtree.
An unvalidated name like "../.." escaped files_dir and deleted
arbitrary directories (path traversal).
- legacy page_index(): restore the node_id/summary/text/description
enhancements. IndexConfig now carries booleans (pydantic coerces the
legacy 'yes'/'no' strings at the boundary), but page_index_main still
compared `opt.if_add_node_id == 'yes'` — always False — so every
enhancement was silently skipped for legacy-API callers. Conditions
now branch on the booleans, matching pageindex/index/page_index.py.
- LegacyCloudAPI._request: bound every request with a timeout
(30s, 120s read timeout for streamed responses) so a dead connection
can't hang legacy submit/poll/chat callers forever. The legacy
contract tests pinned the missing timeout; updated to pin its
presence instead.
Adds regression tests: path-traversal rejection, 'yes'/'no' -> bool
coercion, and timeout assertions.

Fixes the cloud/local contract mismatches from the PR #272 review
(verified against the official API docs — the cloud API has no
folder/collection endpoints publicly, GET /docs supports limit<=100
with offset):
- query_stream: emit a terminal answer_done event with the full answer
(same contract as the local backend); raise CloudAPIError instead of
disguising HTTP errors as answer events; move the initial connect
inside try so a connection failure can no longer strand the consumer
awaiting a sentinel that never arrives
- _request: rewind file objects before retrying so a transient 5xx/429
during upload no longer re-sends an empty multipart body; carry the
HTTP status on CloudAPIError (status_code) and keep the last status
in the max-retries error
- list_documents: paginate with limit/offset instead of a hard-coded
limit=100, so >100-doc collections are no longer silently truncated
(whole-collection queries rely on this list)
- folders: treat only 403/404 as "folders unavailable" (warned via
warnings.warn instead of an invisible logger.warning, matched on
status_code instead of a "403" substring); transient errors now
propagate instead of being permanently cached as folder_id=None
- error taxonomy parity: cloud doc endpoints map HTTP 404 to
DocumentNotFoundError; local get_document raises DocumentNotFoundError
instead of returning {}; local delete_document raises on missing
doc_id instead of silently deleting nothing
- cloud get_document warns that include_text is not supported instead
of silently ignoring it
Adds regression tests for each fix (11 new tests).

- Collection.query and Backend.query/query_stream accept doc_ids as
str, list[str] or None. Single str is normalized to [str] inside each
backend; bare [] is rejected with ValueError at both layers.
- wrap_with_doc_context wraps the scoped doc list in <docs>...</docs>
and SCOPED_SYSTEM_PROMPT instructs the agent to treat that block as
data, not instructions (defense against prompt injection via
auto-generated doc_description).
- _require_cloud_api now distinguishes api_key="" from api_key=None;
the former gives a targeted error pointing at the empty-string vs
fall-back-to-local situation when legacy SDK methods are called.
- Legacy PageIndexClient.list_documents docstring spells out the
return-shape difference vs collection.list_documents() to flag a
silent migration footgun (paginated dict with id/name keys vs plain
list[dict] with doc_id/doc_name keys).
- Remove dead CloudBackend.get_agent_tools stub (not on the Backend
protocol; only ever returned an empty AgentTools()) and the
SYSTEM_PROMPT alias (OPEN_/SCOPED_SYSTEM_PROMPT are the explicit
names now).
- README quick start and streaming example now pass doc_ids; new
multi-document section shows both str and list forms.
- examples/demo_query_modes.py exercises all five query-mode cases
(single-doc, multi-doc with/without env var, scoped single, scoped
multi) for manual verification.
- get_agent_tools branches on doc_ids:
- scoped (doc_ids=[...]): drops list_documents and hard-enforces a
whitelist on the remaining tools; system prompt switches to
SCOPED_SYSTEM_PROMPT (no list_documents instruction); doc list +
summaries are prepended to the user message via wrap_with_doc_context.
- open (doc_ids=None): unchanged 4-tool agent loop.
- list_documents now exposes doc_description (sqlite + cloud).
- Collection.query emits UserWarning when doc_ids is None and the
collection holds >1 documents; PAGEINDEX_EXPERIMENTAL_MULTIDOC=1
silences it. Single-doc collections skip the warning; empty
collections raise ValueError.
- Agents SDK tracing upload disabled by default (avoids SSL timeouts);
PAGEINDEX_AGENTS_TRACING=1 re-enables it.
- README: new SDK Usage section covering local/cloud quick start,
streaming, multi-doc as experimental, and runnable examples.
