- Removed definitive "No files found" message when glob scans time out to prevent misleading claims of file absence.
- Updated timeout notice to explicitly state that results are incomplete and provide actionable guidance on scoping the search.
- Modified TUI renderer to display "No matches before timeout (scan incomplete)" status instead of "No files found" for timed-out scans.
- Implemented a try/catch envelope for browser evaluations to surface detailed page-side JS exceptions and detect unsupported Promise returns.

Fixes#5081

- Added regressions for lease renewal and CAS storage failure propagation.
Fixes#5081
- Added durable SQLite refresh ownership for stored OAuth rows, with canonical re-read before refresh and compare-and-set persistence.
- Routed MCP proactive and forced OAuth refresh through the shared owner so waiters reuse the winner's rotated credential.
- Added MCP regression tests for shared SQLite refresh ownership and stale invalid_grant losers.
Fixes#5081
Rebase onto 16.4.1 landed the entry under the released section; keep
release intent under Unreleased. Dropped the broad models.json regen
that conflicted — surgical xai-oauth-only catalog edits remain.
Drive image-detail clamping from resolved model compat instead of a
provider hardcode, clamp input_image only on known paths, and skip
custom-tool adaptation when freeform is supported.
Seed supportsImageDetailOriginal=false for curated and dynamic xai-oauth
compat, and set the same flag on the eight bundled models.json entries
without regenerating the rest of the catalog.
Fixes#5002
Convert freeform custom_tool_call history to function_call pairs and
clamp input_image.detail original to auto when replaying into xAI OAuth
Responses, so session continuations stop 422ing.
Fixes#5002
