The R09 scholarly hardening routes every hop through check_outbound_url with
block_private=True. On a DNS64/NAT64 network, an IPv4-only host can resolve
through the RFC 6052 Well-Known Prefix. For example, export.arxiv.org resolved
to 64:ff9b::924b:5b2a in the reproduced environment.
CPython classifies that outer IPv6 prefix as reserved, so the URL guard rejected
the request before examining the effective IPv4 destination.
Decode addresses in exactly 64:ff9b::/96 to their embedded IPv4 destination and
evaluate that destination under the strict outbound policy.
The translated target is always checked with private-address blocking enabled.
This prevents the NAT64 prefix from becoming a path to loopback, private,
shared/CGNAT, link-local, multicast, unspecified, or other non-global IPv4
space.
Network-specific translation prefixes are not decoded. In particular,
64:ff9b:1::/48 remains subject to the existing IPv6 policy.
Coverage includes:
- public IPv4 destinations embedded through the RFC 6052 prefix
- loopback, link-local, private, CGNAT, multicast, unspecified, benchmark, and
TEST-NET rejection
- network-specific NAT64 prefixes remaining undecoded
- deterministic scholarly provider tests without live DNS dependence
- redirect query parameter isolation
- relative redirect resolution
- HTTP error fallback behavior
- editor draft GET and DELETE behavior remaining unaffected
R09, R11, and R01 were independently audited and otherwise left unchanged.
- Enforce outbound URL policy on all hops via bounded manual redirects in scholarly lookups
- Guard declared Content-Length in EditorDraftRoute before request body parsing
- Keep scholarly lookup timeouts and budgets as internal constants rather than surface env vars
- Narrow TUI threat-model description around demonstrable host shell bridge behavior
- Add behavioral regression tests for redirect security and pre-parsing body size guards
* refactor(model-routing): centralize explicit foreground fallback policy
Make foreground fallback an explicit per-user, availability-only policy shared by streaming Chat, non-stream Chat, and Agent runs.
Preserve strict defaults, owner/model and credential boundaries, pinned Agent routes, and truthful per-round provenance/accounting. Carry provider-reported model identifiers through native streaming adapters, non-stream responses, and caches, and keep legacy default_model_fallbacks as tombstoned raw storage that generic settings APIs and agent tools cannot expose or mutate.
* fix(agent-loop): restore rebase-dropped qwen routing, workspace prompt, and temperature clamp
* fix(model-routing): thread selected endpoint identity, fix cost classification and fallback eligibility
* fix(chat): restore stream helpers and harden run stop lifecycle
* fix(model-routing): let numeric provider codes win over symbolic rate-limit statuses
* fix(agent-loop): apply qwen temperature and notes-tool clamps per fallback candidate
* fix(chat): honor queued stop across resend and reload canonical terminal on EOF
* fix(chat): track stop queue and cleanup ownership by per-send generation
* fix(agent-loop): preserve requested temperature for non-qwen fallback candidates
* fix(chat): reserve send ownership before any await and scope stop to the current send
* fix(chat): clear the previous run identity at send reservation

Replace substring OpenAI endpoint detection with exact parsed-host matching.
Route gallery image endpoint construction through a constant path allowlist.
Remove client-visible exception and upstream response body leaks from gallery image flows while preserving diagnostics in server logs.
Add focused regression tests for OpenAI host matching, checked endpoint joining, harmonize SSRF hardening, and sanitized client errors.
Add a documentation-only test layout inventory for the first low-risk split of the flat tests directory.
Records the current 28-file area_cli set, including tests/test_research_cli_status.py, and documents validation/non-goals for the future mechanical move.
Closes#3712
Part of #2523
Documentation-only PR continuing #2523. Adds tests/README.md to document helper conventions, validation expectations, and the next test-suite refactor phase.
Test-only refactor continuing #2523. Replaces a repeated core.auth cache eviction pattern in three auth tests with the shared clear_module helper, preserving behavior.
Test-only fix continuing #2523. Updates two stale regression tests so the current broad Python pytest baseline is restored without changing production code.
Test-only fix continuing #2523. Makes the archived-session model-filter test independent of optional multipart packages. The red broad pytest status was classified as unrelated current dev baseline drift before merge.
Test-only refactor continuing #2523. Reuses the shared import-state helper in session-related tests, removes duplicated local save/restore logic, and preserves existing test behavior.
Test-only refactor continuing #2523. Adds a shared import-state isolation helper with focused coverage and migrates two pilot tests that manually preserved sys.modules and parent package attributes.
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.
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.
Restores src.webhook_manager after a review-regression test imports it against a fake src.database. Fixes one focused #2580 CI-baseline pollution bucket.
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.
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.
Removes module-level core.database stubbing from the compare endpoint owner-scope regression test and patches ModelEndpoint per test with monkeypatch. Restores one focused part of the Python CI baseline tracked in #2580.
Updates the stale gallery owner-filter null-user test to match current single-user/auth-disabled behavior. Restores one focused part of the Python CI baseline tracked in #2580.
Updates the PDF marker regression test to check corrupted markers at line level instead of using a broad substring assertion. Restores one focused part of the Python CI baseline tracked in #2580.
Updates the split_chunks containment regression test to use deterministic non-repeating records instead of a repeating fixture that could produce accidental substring matches. Restores one focused part of the Python CI baseline tracked in #2580.
Updates endpoint/model-route test HTTP mocks to accept the verify keyword argument passed by endpoint probing code. Restores one focused part of the Python CI baseline tracked in #2580.
Validate only token-supplied direct base_url values for API-token chat requests, while keeping admin-configured endpoints available for local/LAN providers.
Scope configured endpoint fallback selection to the API token owner, fail closed for unknown token owners, and preserve strict session ownership checks when resuming sessions from chat-scoped API tokens.
Add focused regression coverage for direct base_url SSRF rejection, configured endpoint fallback behavior, token-owner scoping, URL validation, and null-owner session/endpoint handling.
