feat(open-swe): explicit-request reviewer verdicts + shell verdict guard (#214)

* feat(reviewer): explicit-request verdicts + shell verdict guard

Mention-triggered reviews that explicitly ask for a verdict now submit a
real APPROVE/REQUEST_CHANGES through publish_review; auto-reviews stay
advisory (COMMENT). Authorization is enforced in code: publish_review
honors a verdict only when the dispatching webhook set verdict_requested,
which only the explicit-mention path does.

- request_pr_review gains instructions (forwarded verbatim into an escaped
  requester_instructions data block) and request_verdict
- self-review guard downgrades verdicts on Open SWE-authored PRs; stale
  APPROVEs are best-effort dismissed when later findings land
- new PullRequestVerdictGuardMiddleware blocks gh pr review
  --approve/-a/--request-changes/-r, gh api, and curl verdict fallbacks on
  both the coding-agent and reviewer graphs
- shared escape helper moved to agent/utils/prompt_data.py

* fix(reviewer): harden verdict path against security-review findings

Adversarial security review (detector fan-out + proof-or-kill verifier)
of the verdict feature surfaced several verdict-integrity gaps; resolve
the confirmed ones:

- head-drift (high): a mid-run push moves the resolved head, so an APPROVE
  could anchor to an unreviewed commit. Downgrade any verdict to a comment
  when the resolved head differs from the reviewed head (verdict_ignored
  reason head_moved); the push's own re-review submits a fresh verdict.
- self-review fail-open: downgrade to comment when the PR author cannot be
  confirmed (author_unknown), and compare bot logins case-insensitively.
- verdict_submitted now reflects GitHub's returned review state, not just
  the event we asked for, so a coerced APPROVE isn't reported as submitted.
- an authorized verdict whose findings all anchor outside the diff now
  posts as a bodied review with zero inline comments instead of failing.
- add finding_reply to the shared data-block escape tag superset.

 **Engineering conventions & attribution (Sea Haven fork):** the main agent's system prompt is tuned to the Sea Haven engineering handbook — branch names are `feature|bug|hotfix/<kebab-desc>` (optional resolvable `<KEY>-` prefix), PR bodies use `## Summary / Validation / Tests / Notes`, and commit messages follow the handbook format (≤50-char imperative subject, *why* over *what*). The **PR title rule is repo-aware**: when the target repo enforces a conventional-commit title (an `amannn/action-semantic-pull-request` workflow, a `commitlint` config, or a documented requirement in `AGENTS.md` / `CONTRIBUTING.md`), the agent emits a conforming `type(scope): …` title that reads the action's allowed types/scopes — this lets it pass gates like this repo's own `PR Title Lint` and upstream `langchain-ai/open-swe` without manual retitling; otherwise it falls back to the Sea Haven imperative style with no `type:` prefix. PRs that resolve a GitHub issue **auto-link it** in the body (`Closes #<n>` for full fixes, `Refs #<n>`/`Part of #<n>` for partial work, `Closes owner/repo#<n>` cross-repo); because the Sea Haven flow targets `dev` rather than the default branch, the issue closes when `dev` is promoted, not at dev-merge. **No agent/AI attribution is added to any artifact** — no `Co-authored-by` bot trailer, no `Made by [Open SWE]` footer, no "generated by an agent" notes. Commits are currently authored as the **triggering user** (the upstream behavior, which keeps Vercel preview deploys resolvable); flipping authorship to the bot account is tracked separately in issue #11 pending the Vercel-resolvability decision.
 
+**PR reviews & verdicts (Sea Haven fork):** a separate read-only **reviewer** graph reviews PRs and publishes findings as a GitHub Review. Auto-reviews (PR opened / ready-for-review / push re-review / finding replies) are always **advisory** (`event=COMMENT`). When a user's `@openswe` mention *explicitly asks for a verdict* ("approve if it meets the bar; request changes if not"), the coding agent forwards the request via `request_pr_review(instructions=..., request_verdict=True)`; the reviewer run is then authorized — enforced in code via `configurable["verdict_requested"]`, not prompt — to submit a real **APPROVE** or **REQUEST_CHANGES** through `publish_review(verdict=...)`. Requester instructions travel as an escaped `<requester_instructions>` data block (untrusted: they may set focus/merge bar, never override safety rules). Safeguards: verdicts on Open SWE's own PRs are downgraded to comment reviews (self-review guard); unauthorized verdicts are dropped with `verdict_ignored`; a recorded APPROVE is best-effort dismissed when a later review surfaces new findings; and `PullRequestVerdictGuardMiddleware` blocks the shell path on both graphs.

Set `request_verdict=True` ONLY when the user explicitly asked for a verdict (approve / request changes) in their own words — never infer it. Never approve or request changes on a PR yourself via `gh pr review` or the GitHub API; that path is blocked, and verdicts are the reviewer run's job.
 
 **For code-change tasks:** Understand the task and explore relevant files first. Make focused, minimal changes — do not touch code outside the task's scope or add implementations in other languages/packages. Verify with linters and only the tests related to your changes. Then commit, push, and (when a PR is warranted) open/update the draft PR — see Committing below.

-| `e826864d` | #1760 | feat: optional separate LangSmith key/endpoint for sandboxes (#1760) | Deferred | optional separate LangSmith key/endpoint for sandboxes; additive to langsmith.py + proxy auth; useful for fork LangSmith sandbox usage. Re-triage (post-reorg 8356eb34 landed): near-clean — path-remap tax gone; remaining work is the additive reconcile against fork's diverged langsmith.py + proxy auth (integrations/ unmoved). | sandbox-config |
-| `dd5b7bec` | #1761 | fix: capitalize dashboard tool labels (#1761) | Deferred | capitalize dashboard tool labels; post-reorg UI paths; stacks on #1732 (d714586c). Re-triage (post-reorg 8356eb34 landed): path-remap blocker removed — clean pick after #1732. | dashboard-ui |
+| `b5e52925` | #1775 | feat: add structured Linear issue filters (#1775) | Deferred | Clean pick: structured filters for linear_search_issues — stacks directly on #1748 (landed PR #206); zero fork drift on all three files. Ready whenever. | linear-tooling |
+| `81d544bc` | #1765 | feat: Expose more specific AGENTS.md context to Open SWE reviewer (#1765) | Deferred | Near-clean: agents_md.py helper + tests are zero-drift; reviewer.py hunk is small (~39 lines) but lands in the fork's heavily-diverged reviewer — hand-apply the scoped_agents_md wiring onto the fork's fetch_agents_md call sites (reviewer.py ~L404/445/1031). | reviewer-context |
+| `8c8e58bc` | #1776 | feat: connect automations to Slack channels (#1776) | Deferred | Moderate reconcile: Slack-channel wiring for automations. Fork helpers exist (post_slack_top_level_message_with_ts, generate_thread_id_from_slack_thread, slack_id_for_login); completion.py (+233 drift) and schedules.py (+167) need hand-merge; UI automations feature present. Keep backend+UI+tests as one vertical. | automations-slack |
+| `f0897479` | #1778 | feat: surface context window usage in agents UI (#1778) | Deferred | Near-clean: context-window indicator UI is all new files (zero drift); options.py hunk must be re-keyed to the fork's Bedrock/Fireworks model map (fork model IDs differ from upstream's) — add context_window per fork entry rather than taking upstream values. | context-usage-ui |
+| `31263f83` | #1785 | Fix: Fix Stored XSS in ReplyCard.tsx (#1785) | Deferred | SECURITY priority, near-clean: diff is urlencode() hardening of the GitHub OAuth authorize URL in dashboard routes.py auth_login (upstream bot title says ReplyCard.tsx — mismatch, trust the diff). Fork auth_login has the identical f-string URL; hunk applies clean. Port promptly. | sec-oauth-urlencode |
+| `3ea29d3f` | #1789 | Fix: Fix Improper privilege management in server.py (#1789) | Deferred | SECURITY priority, near-clean: adds empty-signature reject to verify_github_signature (utils/github_comments.py) + verify_linear_signature (webhooks/common.py) (title says server.py — mismatch, trust the diff). Both fork functions match at the hunk sites; fork-only verify_jira_secret already guards empty token. Real value: None signature currently raises TypeError in compare_digest. Port BOTH hunks together. | sec-webhook-empty-sig |
 
 _Maintenance: after a `git sync`, add new `dev..upstream/main` SHAs as **Untriaged** (edit `triage.jsonl`) and bump "Last synced". A successful `git cherry-pick -x` auto-moves the row to **Landed** via the `post-commit` journal + `make triage-reconcile`._
