Validated in a combined 3-PR batch worktree off release/v3.8.51 tip (a sibling PR from the same author, #11495, was held out — a typecheck error in zai-web.ts only reproduced with this PR + #11495 boarded together, and cleared without #11495; isolated this PR alone confirmed clean on its own too, so the interaction belonged to #11495's side — see its comment).
- Golden lock: executor-map-golden.test.ts — passes byte-identical (same keys, classes, provider identities, dispatch guards)
- Focused tests part of batch's 94/94 node:test run
- typecheck:core, file-size, changelog-integrity, complexity, cognitive-complexity — all OK
- Full-repo lint: 228 pre-existing dashboard react-hooks/* findings, unrelated to this diff
Thanks for the measured, careful methodology here — the golden-lock contract plus the isolated DATA_DIR benchmarking make this an easy PR to trust despite the wide surface (72 files).
Requests AgentUrlConfig from Cursor with each selected account token and selects the account's actual server-assigned Agent endpoint (agentUrl/agentnUrl) instead of a fixed global/us host, which fails for teams pinned to a different region. Caches validated endpoints by connection+token. Closes#10802.
Validated in an isolated worktree boarded onto origin/release/v3.8.50 (0 conflicts, 4 files):
- 18/18 focused tests pass (cursor-agent-host, cursor-apikey-provider).
- provider-translate-path-golden.test.ts initially failed — traced to a pre-existing base-red (stale golden snapshot left by an earlier freebuff merge, #10531, unrelated to this PR) and confirmed it reproduces on the pure release tip without this PR's changes. Fixed directly on release/v3.8.50 (mechanical key-ordering regen, values unchanged) rather than folding it into this PR's scope; green after merging that fix in.
- check-file-size, check-changelog-integrity: OK.
- typecheck:core: clean.
- check-complexity / check-cognitive-complexity: OK, both under baseline.
- Author additionally validated live: a real Cursor request selected agentn.us.api5.cursor.sh and returned HTTP 200/PING.

Merged via merge-train (release/v3.8.50, batch1 2026-08-20) — static gates (typecheck/file-size/complexity/cognitive/changelog) green on the combined tree; test:unit reds observed in the boarded run were verified pre-existing on the pure release tip (unrelated flake), not caused by this PR. Thanks for the contribution!
