Thinking Path

T3 of #16654 (PR 1 of 3 -- see "Single-issue rationale" below): the search and RAG routes never applied ownership/visibility filtering, so a PRIVATE or SYSTEM fact was returned to any signed-in caller who could reach those paths. #16674's guard (repo_tests/kb_read_visibility_allowlist.py) enumerates every unfiltered KB read call site precisely -- 34 entries tagged TRACKED_GAP #16665 across 15 files, a larger and more precise scope than #16665's own issue text (which names ~11 top-level routes; many of the 34 are the inner helper functions beneath those routes that actually touch the KB).

This PR covers the two canonical search entry points -- api/knowledge_search.py (POST /search) and api/knowledge_search_aggregator.py (/multi-source/search, /context, /graph) -- plus two file extractions the added filtering code required. Remaining files split into two further PRs (CRUD-ish routes; AI/RAG/MCP/lifecycle), per the owner's guidance once this PR's own diff proved large enough to be "a full security review by itself."

Per the owner's decision on #16654 (2026-09-13): explicit read APIs let an admin read any fact.

What Changed

api/knowledge_search.py -- threaded user_id/user_org_id/user_group_ids/is_admin through all three search paths (RAG, aistack/advanced, basic+reranking) down to the three raw-KB-read call sites (_execute_kb_search, _search_with_all_queries, _aistack_search's three branches).

api/knowledge_search_aggregator.py -- same threading through /search, /context, /graph:

  • _search_facts, _get_facts_for_graph: filtered via filter_search_results_by_permission. get_facts_in_category returns flat fact dicts (owner_id/visibility at the top level), unlike kb.search()'s already-metadata-nested results -- wrapped as {**fact, "metadata": fact} before filtering so both shapes work through the one helper.
  • _expand_fact_relations, _process_relations_for_citations: a related fact reached via the relation graph (target_fact/source_fact) is a KB fact like any other. Filtered per-item via a new _related_fact_is_accessible helper (wraps the flat _get_fact_content-shaped dict the same way), since a relation is not an access grant.
  • get_llm_context: filters the fact-search results feeding the LLM prompt itself, not just a display list.
  • _get_fact_relations_for_graph: not modified. Reclassified in the allowlist from TRACKED_GAP #16665 to SCOPED, with the reasoning recorded inline: it receives fact_ids already filtered by _get_facts_for_graph's output (both functions share the one caller, get_multi_source_graph); it re-checks both ends of every returned edge against that same fact_ids set (if target_id not in fact_ids: continue); and it calls kb.get_fact_relations(..., include_fact_details=False), so no fact content is ever fetched here -- only from/to/type/strength. Safe by construction (bounded to an already-vetted ID set), not by an active per-call check. The guard trusts this judgement going forward; flagging clearly so it's checked, not just accepted.

Extractions (both pushed the touched file past its grandfathered file-size ceiling, #14236 -- the exemption freezes the size it was granted for, not a license for more):

  • api/knowledge_search_analytics.py: the 3 analytics endpoints from knowledge_search.py (search_analytics, record_click, expand_query -- none return KB facts).
  • api/knowledge_search_documentation.py: the documentation-search subsystem from knowledge_search_aggregator.py (indexed AutoBot docs, not KB facts -- no visibility concern).
  • Both registered in core_routers.py under their original /knowledge_base prefix, so every URL is unchanged.
  • Both ceilings lowered to the files' new real sizes (820, 937) after extraction, since the ratchet only turns down.

Self-caught bug: both new router files initially imported their response-schema classes from knowledge.schemas (a different, unrelated package) instead of api.schemas_knowledge -- would have broken app startup, since core_routers.py imports both directly. Caught by the pre-push hook's own pytest collection failing, not by manual tracing; fixed in a follow-up commit before this PR left draft.

Shrinks 8 entries from repo_tests/kb_read_visibility_allowlist.py (_aistack_search, _execute_kb_search, _search_with_all_queries, _expand_fact_relations, _get_facts_for_graph, _process_relations_for_citations, _search_facts, get_llm_context) and reclassifies 1 (_get_fact_relations_for_graph, _T3 -> SCOPED). MAX_ALLOWLISTED 84 -> 76.

Verification

  • Two new tests (knowledge_search_visibility_16665_test.py, knowledge_search_aggregator_visibility_16665_test.py) drive the real route functions with a real KnowledgeOwnership.check_access (not mocked), proving the routes' actual wiring:
    • user A's PRIVATE fact is not returned to user B
    • is returned to A
    • is returned to an admin via an explicit read
  • Updated the 3 existing tests in knowledge_search_aggregator_test.py that called the modified functions directly, with placeholder user_id/is_admin values (their kb.search() mocks return empty results, so nothing for the filter to act on -- they still verify the quarantine-filter behavior they were written for).
  • Pre-push hook ran all 4 relevant test files directly at the final head: all pass.
  • Verified no other file imports the moved analytics/documentation functions from their old locations before moving them.

Risks

Low-to-moderate: the diff is one mechanical pattern (thread four params, filter before return) applied at most call sites, but the aggregator's relation-graph functions needed real judgement (the flat-vs-nested shape mismatch, and the SCOPED reclassification) rather than pure mechanics -- both are called out explicitly above for review rather than buried in the diff.

Single-issue rationale

T3 is one sub-issue of the #16654 umbrella; #16665's own scope (34 call sites across 15 files) is large enough that the owner asked for a three-way split once this PR's own diff (2 files + 2 extractions) proved to be "a full security review by itself": this PR (search + aggregator), a CRUD-routes PR, and an AI/RAG/MCP/lifecycle PR. All three Refs #16665; the last lands Closes #16665 once every AC is met with evidence.

Changelog fragment

  • Security fix -- fragment to follow once the full T3 scope lands (partial fix so far, across 3 PRs).

Checklist

  • Code follows AutoBot patterns from CLAUDE.md
  • Tests added or updated
  • Documentation updated if behavior changed (N/A)
  • Pre-commit hooks pass

Summary by CodeRabbit

  • Bug Fixes

    • Search results, related facts, graph data and LLM context are now filtered according to the signed-in user’s permissions.
    • Administrators retain access to authorised private knowledge, while users can access their own permitted content.
  • New Features

    • Knowledge-search analytics endpoints are available for performance metrics, click tracking and query expansion.
    • Documentation search and documentation index statistics are available through dedicated knowledge-base endpoints.

… caller's access (#16665, #16654)

api/knowledge_search.py's canonical search endpoint never applied
ownership/visibility filtering -- any signed-in caller could read
another user's PRIVATE fact through it. Threads user_id/user_org_id/
user_group_ids/is_admin from the route's current_user through all
three search paths (RAG, aistack/advanced, basic+reranking) down to
the three call sites that actually fetch raw results from the KB
(_execute_kb_search, _search_with_all_queries, _aistack_search's three
branches), applying knowledge.search_filters.filter_search_results_by_permission
before any result reaches the caller.

Per the owner's decision on #16654: this is an explicit read API, so
an admin (is_admin_role(current_user.get("role"))) reads any fact,
same as knowledge_ownership.py/knowledge_collaboration.py's existing
correct callers.

Test (real KnowledgeOwnership.check_access, not mocked, so it proves
the route's wiring and not just that a mock was called):
- user A's PRIVATE fact is not returned to user B
- is returned to A
- is returned to an admin via an explicit read

Extracted the three analytics endpoints (search_analytics, record_click,
expand_query -- none of which ever return KB facts) into their own
api/knowledge_search_analytics.py: the added filtering code pushed
knowledge_search.py past its grandfathered file-size ceiling (#14236,
851 lines), and that exemption freezes the size it was granted for
rather than licensing more. Registered the new router in
core_routers.py under the same /knowledge_base prefix, so every route
keeps its existing URL. Lowered the grandfather ceiling to the file's
new real size (820), since the ratchet only turns down.

Shrinks 3 entries from repo_tests/kb_read_visibility_allowlist.py
(_aistack_search, _execute_kb_search, _search_with_all_queries),
MAX_ALLOWLISTED 84 -> 81.

Walkthrough

Knowledge search routes now apply caller-based fact visibility filtering across search, multi-source, context, relation, and graph responses. Analytics and documentation routes moved into separate authenticated modules. Router registration and regression tests were updated.

Changes

Knowledge search access handling

Layer / File(s) Summary
Search permission filtering
autobot-backend/api/knowledge_search.py
The search endpoint extracts user and admin context. All search paths filter results and recalculate result counts before returning them.
Multi-source visibility enforcement
autobot-backend/api/knowledge_search_aggregator.py
Multi-source search, LLM context, relations, and graph results filter facts with the caller’s permissions. JSON metadata is decoded before filtering.
Extracted search routes
autobot-backend/api/knowledge_search_analytics.py, autobot-backend/api/knowledge_search_documentation.py, autobot-backend/initialization/router_registry/core_routers.py
Analytics and documentation endpoints were moved into separate authenticated routers. Both routers are registered under the knowledge-base prefix.
Visibility regression coverage
autobot-backend/api/*visibility_16665_test.py, autobot-backend/api/knowledge_search_aggregator_test.py, repo_tests/kb_read_visibility_allowlist.py
Tests cover private-fact access for users, owners, and admins, metadata decoding, updated parameters, and reduced allowlist entries.

Explanation

The PR applies caller-based filtering to the canonical POST /search, /multi-source/search, /context, and /graph paths. The summary also supports owner, other-user, and admin coverage for search, plus owner coverage for the category-filtered graph path. However, issue #16665 requires every listed route to use the fixed helpers and requires a test per route. The PR leaves the other listed routes, including suggestions, grounding, MCP, AI stack, RAG, graph RAG, librarian, and knowledge graph routes, for later work. The evidence does not show per-route private-fact tests for all four changed canonical routes. This does not meet the issue acceptance criteria.

Resolution

Implement caller-based permission filtering and preserve or add research quarantine filtering on every remaining route listed in issue #16665. Add a regression test for each listed route that verifies a private fact is hidden from another user and visible to its owner and an admin. Add the missing canonical-route tests if existing tests do not provide that coverage.

Notice: 29 open PRs — past the runaway threshold (25)

There is no PR queue limit, and this is not a request to defer this PR. Work proceeds one issue at a time without a cap on open PRs; review capacity is the constraint.

This notice only means the count is high enough to be worth a glance for a runaway — something opening PRs in a loop, or a merge pipeline that has stalled so nothing is draining.

Currently open:

If the queue is draining normally, ignore this. Otherwise:

  1. Check whether CI is dispatching at all — see the ci-dispatch-watchdog status on these PRs
  2. Merge the ones whose CI has finished and review has passed: gh pr merge <number> --squash --delete-branch
  3. Look for a loop opening near-identical PRs

✅ SSOT Configuration Compliance: Passing

🎉 No new hardcoded values of either class — ssot and other both block.

Known backlog in pipeline-scripts/hardcoded_values_baseline.txt is suppressed and tracked in #14371.

…ults by the caller's access (#16665, #16654)

api/knowledge_search_aggregator.py's /multi-source/search, /context and
/graph routes never applied ownership/visibility filtering. Threads
user_id/user_org_id/user_group_ids/is_admin from each route's
current_user through to every call site that fetches raw facts or
relation content from the KB:

- _search_facts, _get_facts_for_graph: filter_search_results_by_permission
  on the raw fact list (get_facts_in_category's flat fact dicts are
  wrapped with a "metadata" view first, since that shape differs from
  kb.search()'s already-nested results).
- _expand_fact_relations, _process_relations_for_citations: a related
  fact reached via the relation graph (target_fact/source_fact) is a KB
  fact like any other -- filtered per-item via the new
  _related_fact_is_accessible helper, since a relation is not an access
  grant.
- get_llm_context: filters the fact-search results feeding the LLM
  prompt itself, not just the display list.
- _get_fact_relations_for_graph: not touched -- reclassified in the
  allowlist as SCOPED rather than removed. It receives fact_ids already
  filtered by _get_facts_for_graph, both ends of every returned edge are
  re-checked against that same set, and include_fact_details=False means
  it never fetches fact content -- safe by construction, not by an
  active check.

Extracted the documentation-search subsystem (indexed AutoBot docs, not
KB facts -- no visibility concern) into a new
api/knowledge_search_documentation.py: the added filtering code pushed
this file past its grandfathered ceiling (#14236, 967 lines). Registered
the new router in core_routers.py under the same /knowledge_base prefix
-- every URL unchanged. Lowered the ceiling to the file's new real size
(937), since the ratchet only turns down.

Updated the 3 existing tests in knowledge_search_aggregator_test.py
that called the modified functions directly with placeholder
user_id/is_admin values (empty kb.search() results, nothing for the
filter to act on). New test
(knowledge_search_aggregator_visibility_16665_test.py, real
KnowledgeOwnership.check_access, not mocked) covers the /search route:
user A's PRIVATE fact hidden from user B, visible to an explicit admin
read.

Shrinks 5 entries from repo_tests/kb_read_visibility_allowlist.py
(_expand_fact_relations, _get_facts_for_graph,
_process_relations_for_citations, _search_facts, get_llm_context) and
reclassifies 1 (_get_fact_relations_for_graph, _T3 -> SCOPED),
MAX_ALLOWLISTED 81 -> 76.

Refs #16665, #16654
… routers (#16665)

Both api/knowledge_search_analytics.py and api/knowledge_search_documentation.py
imported KnowledgeDocumentationSearchResponse/KnowledgeDocumentationStatsResponse/
RecordClickResponse/ExpandQueryResponse/SearchAnalyticsResponse from
knowledge.schemas, a different, unrelated package (knowledge/schemas/,
which exports things like KnowledgeSearchResponse) -- these classes
actually live in api/schemas_knowledge.py, matching the original
knowledge_search_aggregator.py import this code was extracted from.

Broke module import entirely (core_routers.py imports both routers
directly, so this would have failed app startup), caught by the
pre-push hook's own pytest collection failing on
knowledge_search_aggregator_test.py rather than by me tracing it
manually -- CI is still the authority here, this is the fix it asked for.

…act metadata before filtering (#16665)

Two real bugs from the code-reviewer pass on #16691, both confirmed
against source (and the import one against this PR's own CI):

1. knowledge_search_analytics.py's schema import went the wrong
   direction in the earlier "fix" commit -- SearchAnalyticsResponse/
   RecordClickResponse/ExpandQueryResponse actually live in
   knowledge.schemas (matching knowledge_search.py's own still-correct
   KnowledgeSearchResponse import), not api.schemas_knowledge. CI's
   autofix-types job confirmed: "cannot import name 'ExpandQueryResponse'
   from 'api.schemas_knowledge'".

2. _get_facts_for_graph's category-filter branch and
   _related_fact_is_accessible wrapped the raw Redis fact hash's
   "metadata" field directly as the dict filter_search_results_by_permission
   checks -- but knowledge/facts.py writes that field as
   json.dumps(metadata), a STRING, not a dict. check_access() read
   owner_id=None off the un-decoded string every time, defaulting every
   fact to PRIVATE-with-no-owner-match and denying it to everyone,
   including the fact's own owner (fail-closed, not a leak, but a
   silent functional regression on /multi-source/graph's category
   filter and every relation-graph fact). Added _decode_fact_metadata
   to parse the field properly, matching how api/knowledge_ownership.py's
   already-correct kb.get_fact() path handles the same shape.

New regression tests exercise both previously-untested paths directly:
_decode_fact_metadata's own JSON parsing, and _get_facts_for_graph with
a real category_filter proving the owner sees their own fact again.

Lowered knowledge_search_aggregator.py's file-size ceiling to its final
real size (951) rather than the earlier intermediate value (937) set
before this fix's lines were added -- still well under the original
grandfathered 967, and the ratchet's invariant is against what's
merged on main, not against an unmerged PR's own intermediate commits.
Auto-regenerated (py3.14) to match the backend and/or SLM backend
schema so the required verify-generated-types gate(s) pass.
Triggered by auto-fix-generated-types.yml.

Initialise query before the import.

If knowledge.search_quality raises ImportError, execution enters this handler before Line 127 assigns query. Evaluating [query] then raises UnboundLocalError, so the endpoint returns an error instead of its documented unavailable fallback.

Proposed fix
 async def expand_query(request: dict):
+    query = request.get("query", "")
     try:
         from knowledge.search_quality import get_query_expander

         if not query:

Authorization Bypass

Reachability: External
Exploitability: Moderate
CWE: CWE-863 — Incorrect Authorization

Enforce research quarantine in every named retrieval path.

_execute_kb_search, _search_with_all_queries, and both direct branches in _aistack_search call the knowledge base without RESEARCH_QUARANTINE_FILTER. The basic and RAG paths inherit this gap. The category graph branch separately reads Redis facts through get_facts_in_category, which also has no quarantine exclusion. Apply the filter before permission filtering or RAG synthesis, and add equivalent collection exclusion before category facts enter graph construction. Keep the existing filters in _search_facts, get_llm_context, and non-category graph retrieval.

Filter each query result before content deduplication.

_search_with_all_queries records content in seen_content before filter_search_results_by_permission runs. If an inaccessible result precedes an accessible result with the same content, the accessible result is discarded and the final filter removes the inaccessible result. The reachable _rag_search path can therefore lose an accessible document or return no result for that content. This is a narrow result-loss edge case, not an authorisation bypass.

Apply permission filtering to each query_results list before updating seen_content.

_get_fact_relations_for_graph SCOPED reclassification — verified the ID-scoping is correct by construction: `fact_ids` passed in comes only from `_process_facts_into_nodes(facts, ...)`, where `facts` is already permission-filtered by `_get_facts_for_graph` via `filter_search_results_by_permission`. The relation lookup then checks both ends — the loop only iterates `fact_ids` (source already visible) and drops any edge whose `target_id not in fact_ids` (target must also be in the visible set) — combined with `include_fact_details=False`, no fact outside the caller's visible set is exposed, not even its existence via an edge.

get_facts_in_category flat-fact wrapping — `_decode_fact_metadata` fixes a real bug: `get_facts_in_category`'s facts carry metadata as a JSON string (unlike `kb.search()`'s pre-decoded results); previously this silently produced `owner_id=None` for every fact, over-denying even the owner. Fixed with a safe fail-closed decode (bad JSON / non-dict → `{}`, which denies rather than grants).

Per-item relation filtering — `_related_fact_is_accessible` applies the same `filter_search_results_by_permission` check to facts reached via the relation graph, not just direct search hits ("a relation is not an access grant"). Correct.

Also traced every return path in `knowledge_search.py`'s `search()`/`_aistack_search`/`_rag_search`/`_execute_kb_search` — all now funnel through `filter_search_results_by_permission` before returning, including both the VectorSearchEngine and legacy-fallback branches (previously two separate early returns, now unified so a future path can't be added without the filter). The two size-ceiling extractions (`knowledge_search_analytics.py`, `knowledge_search_documentation.py`) are pure moves — the docstring itself states, and the code confirms, that those routes never return KB facts (search-quality metrics / product-doc search), so no visibility concern there. `filter_search_results_by_permission` itself is unmodified by this PR (already fail-closed from #16669).

CI: no FAILURE/ERROR/TIMED_OUT checks. Mergeable.

…t clear (#16665)

repo_tests/kb_read_visibility_guard_test.py's static scan marks a KB read
"filtered" only if one of the 6 recognized filter-helper names is called
directly within the SAME function body (ast.walk(child), where child is
that function's own subtree -- a call into a locally-defined helper one
level down is invisible to it).

_expand_fact_relations and _process_relations_for_citations both filter
every related fact via _related_fact_is_accessible, which itself calls
filter_search_results_by_permission -- genuinely filtered, but through
exactly that one level of indirection the scan doesn't see. Both were
removed from the allowlist in the original fix commit on the (incorrect)
assumption that adding the filtering call was sufficient to clear the
guard; CI's python-suite shard 4/12 caught the gap.

MAX_ALLOWLISTED: 76 -> 78 (two entries restored). Still 84 -> 78 against
main, where nothing in #16665 has landed yet -- the "never rises" ratchet
tracks merged main, not this PR's own intermediate commits.

Delta review at a4ffd53 (from bd54234): approve.

Verified both restored functions genuinely filter every relation on every path, not just the added-then-forgotten-allowlist-entry claim:

  • `_expand_fact_relations`: both the `outgoing` and `incoming` loops gate their only content-producing calls (`_process_outgoing_relation`/`_process_incoming_relation`) behind `if await _related_fact_is_accessible(...)` — no branch skips it.
  • `_process_relations_for_citations`: the only content-producing call (`_build_relation_context`, which appends fact content into the LLM context) is behind the same check inside the `for rel in relations["outgoing"][:2]` loop. The unconditional `context_parts.append("## Related Information\n")` before it is a static header, not fact content, so no leak there even when zero relations pass.

Both correctly reuse `_related_fact_is_accessible`, already verified in my first pass on this PR. Agree with the guard-limitation diagnosis: it's a genuine single-hop-AST blind spot (checks for a filter-helper call in the same function body, not one level of indirection down), not a case where the code stopped filtering.

CI: no FAILURE/ERROR/TIMED_OUT checks. Mergeable.

… can't clear (#16665)

repo_tests/kb_read_visibility_guard_test.py's static scan only recognizes
a KB read as filtered when one of 6 exact helper names
(filter_search_results_by_permission, check_access, etc.) is called
directly in the same function body. _get_or_compute_category_counts
(now api/knowledge_category_counts.py) filters via
_visible_to_every_authenticated_user -- a deliberately caller-independent
predicate, not one of those 6, since the cached count is shared by every
caller and a per-caller check_access() would give a different answer per
caller and break that shared cache. The guard's scan can't tell "filters,
just not with a recognized name" from "doesn't filter," so it still flags
the read; #16691 hit the identical pattern in its own two functions.

Restored the allowlist entry with the reasoning above. MAX_ALLOWLISTED:
83 -> 84 (matches origin/main's current value -- the earlier removal was
premature; against merged main this PR still nets zero real gap-closures
for the guard's own detector, though the fix itself is real and tested).
