Hand re-key those four; keep the whole vertical (tool + plan_mode + thread_api + 4 test files) on one side. |  |
 | `e51abe14` | #1754 | fix: skip oversized images before model calls (#1754) | Deferred | Desirable: 10MB image size cap + 'image omitted' text block before model calls, prevents oversized-image model failures. Conflicts only because the fork hardened fetch_image_block (SSRF redirect guard, host-only logging) — hunks are compatible; re-key the size check around the fork's guarded fetch and port impl + test together. |  |
 | `0ed560a5` | #1779 | fix: settle review checks after run failures (#1779) | Deferred | Desirable: run-failure completion webhook now settles reviewer check runs left open when the graph dies (_settle_failed_reviewer_check; uses settle_review_check_run + review_check_pending_result, both already in the fork's review/publish.py from the #214/#215 ports). Conflict is fork drift in completion.py (failure-reply customizations); re-key the new helper in and port with its 159-line test. |  |
 | `bedc57b8` | #1796 | fix: cap execute output by making SandboxBackendProxy a BaseSandbox (#1796) | Deferred | Real fix (unbounded execute stdout pulled into the worker → OOM risk) but inapplicable at the fork's deepagents==0.6.12: no capture-offload API exists (ExecuteOffloadResult / execute_accepts_timeout absent; FilesystemMiddleware has no _resolve_capture BaseSandbox gate), so the bug it fixes cannot occur yet. Re-triage together with deferred #1745 (deepagents 0.6.12→0.7.x bump) — landing that bump makes this fix required. Fork's SandboxBackendProxy has diverged (sync-era, bound_repo repo-binding, no reconnect machinery): hand-apply the execute_with_offload/aexecute_with_offload delegation onto the fork proxy rather than cherry-pick. |  |
-| `a77c4e47` | #1799 | fix: show current shared thread in sidebar (#1799) | Deferred | Desirable dashboard fix: sidebar now surfaces the currently-open shared thread (org-member 'Open in Web' links) when it falls outside the caller's own list — _sidebar_active_thread_summary + active_thread_id param; fork has the same include_all/org-member read path in thread_api.py. Cherry-picks CLEAN onto dev (merge-tree probe: zero conflicts); port with its thread-api tests + sandbox_id e2e spec + AgentsSidebar/queries UI as one vertical. |  |
 | `b67215ed` | #1780 | feat: link originating Slack threads (#1780) | Deferred | Desirable for the Slack-heavy fork: dispatch records the originating Slack permalink in thread metadata (webhooks/common.py), open_pull_request embeds an 'Originating Slack thread' link in the PR body (gated to private repos), and the sidebar menu links it. Impl files auto-merge (thread_api / open_pull_request / webhooks/common); conflicts are fork drift in prompt.py (customized prompt constants), tests/e2e/harness.py, tests/slack/test_slack_context.py — hand re-key those; keep backend + UI (AgentsSidebar, types) + e2e dashboard spec as one vertical. |  |
 | `7d79d300` | #1804 | chore(deps): bump deepagents to 0.7.0b1 pin (#1804) | Deferred | Rides the deferred #1745 deepagents bump: 0.7.0a7→0.7.0b1 pin + wcmatch>=11.0 uv override (langchain-e2b's e2b dep still caps wcmatch<11.0). Fork is pinned deepagents==0.6.12 — and langsmith==0.10.10 already satisfies the new >=0.10.9 floor — and never took the a7-era HARNESS_EXCLUDED_MIDDLEWARE code its prompt.py hunk deletes, so nothing applies standalone. Re-triage as one cluster: #1745 (bump, now targeting 0.7.0b1) + #1796 (offload delegation) + this pin/override. |  |
 | `0e2eefbc` | #1801 | chore: bump default sandbox resources and delete-after-stop (#1801) | Deferred | Capacity/cost policy, not a correctness fix: defaults 2→4 vCPU, 7936MiB→16GiB mem, 32→128GiB FS, stopped-sandbox delete 24h→14d. Would materially raise LangSmith sandbox spend on sh-openswe unless prod env already overrides; all five values are env-overridable today. Decide prod sizing first (ops decision), then adopt or reject. Textual conflict is only fork drift in integrations/langsmith.py (sync-era SandboxClient, reconnect constants absent) — the constants re-key trivially; docs hunks auto-merge. |  |
