refactor: durable interrupt dispatch + completion webhook (#1621)
* wip(rebuild): core reliability spine

- remove PR-babysitting (ci_autofix + ci_monitor graph + webhook wiring)
- dispatch core: agent/dispatch.py with multitask_strategy=interrupt +
  durability=sync + completion webhook; reroute all webhook + plan triggers;
  drop the racy in-process lock + is_thread_active busy-check
- completion webhook: agent/completion.py + /webhooks/run-complete loopback
  route for failure/timeout replies (idempotent)

* feat(rebuild): async tools, reconcile, shared http timeouts, assembly tuning

Parallel batch on top of the reliability spine:
- async-ify all 24 tools (drop asyncio.run; requests->httpx); re-implement the
  http_request/fetch_url SSRF + DNS-rebinding defense httpx-natively and harden
  the IP check to 'not is_global' (+ IPv4-mapped unwrap)
- reconcile.py: stale pending-run sweep (threads.search -> per-thread runs.list
  -> cancel_many), wired into the scheduler graph via task='reconcile'
- shared DEFAULT_HTTP_TIMEOUT (agent/utils/http.py) on every bare
  httpx.AsyncClient() across utils/dashboard/webapp/middleware
- run budget: MODEL_CALL_RECURSION_LIMIT 5000->250
- fix stale OpenAI->Anthropic fallback id (claude-opus-4-5 -> 4-8)
- drop redundant custom repair middleware (deepagents auto-adds PatchToolCalls)
- confirm tool-result eviction + summarization auto-wired via backend
- slim system prompt ~8% (full harness-profile rewrite deferred)

* feat(rebuild): harness-profile prompt + split webhooks out of webapp

- prompt.py: own the system prompt via a registered harness profile
  (OPEN_SWE_SHARED_BASE, kept neutral so the read-only reviewer/analyzer that
  share it stay safe), registered across all 4 providers; per-thread values
  stay in construct_system_prompt. Assembled main-agent prompt ~6.8k -> ~3.1k
  tokens (~55% smaller); de-duped PR/commit/suite/force-push guidance; dropped
  ALL-CAPS markers.
- webapp.py 3325 -> 1890 LOC: moved 14 per-source handlers into
  agent/webhooks/{linear,slack,github}.py; webapp re-exports them for the
  routes + tests; moved handlers reach shared helpers via the webapp namespace
  to preserve the test suite's monkeypatch targets.

Full suite: 1168 passing, lint clean.

* Restore MODEL_CALL_RECURSION_LIMIT to 5000 for long-running tasks

Reverts the 250 cap from the run-budget change — long-running tasks legitimately
need many model calls. The notify_step_limit_reached safety net still fires if a
run does hit the cap, so runs end with a signal either way.

* fix: address PR review (auth, SSRF, interrupted status, redirect headers)

- completion.py: drop `interrupted` from failure statuses — with
  multitask_strategy=interrupt a follow-up ends the prior run as interrupted,
  which is healthy, not a failure to report. [open-swe]
- /webhooks/run-complete: shared-secret auth — dispatch appends ?token= when
  RUN_COMPLETE_WEBHOOK_SECRET is set; route verifies via hmac.compare_digest.
  [corridor-security]
- SSRF: extract the URL validator to agent/utils/url_safety.py and apply it
  before server-side image fetches in multimodal.fetch_image_block.
  [corridor-security]
- http_request: preserve caller headers/extensions across redirect hops instead
  of dropping them on the first hop. [open-swe]

* chore: remove REBUILD_PLAN.md (planning doc, not needed in the repo)

* fix: fail closed on run-complete webhook auth when secret unset

Corridor follow-up: verify_run_complete_token returns False (not True) when
RUN_COMPLETE_WEBHOOK_SECRET is unset, so the public route is never
unauthenticated. Logs a startup warning when the secret is absent, and dispatch
skips registering the webhook when there's no secret (no rejected callbacks).

fix: keep review check on follow-up commits, drop neutral conclusion (#1486)
* fix: keep review check visible on follow-up commits and stop using neutral

The "Open SWE Review" check completed as `neutral` whenever findings were
surfaced, which GitHub renders as a confusing "neutral check" group. Always
complete it as `success` (informational/non-blocking), matching Devin and
Corridor — the finding count stays in the title and findings post as comments.

Also create a fresh check run on the new head SHA in the push re-review path:
GitHub only shows check runs on a PR's current head, so the check vanished
after a follow-up push (and the stale id settled on an outdated commit).

fix: reviewer resolves GitHub App token at run start, not via cross-process cache (#1409)
Reviewer/push runs execute in a worker process, but the GitHub token was
cached by the webhook handler in the API server process — a different
process — so the worker's in-process cache was always cold. resolve_github_token
then failed (User not authenticated / Unknown source: github_push) and only the
app-token fallback kept reviews working, noisily.

The reviewer always acts as the GitHub App (open-swe[bot]), so resolve the
installation token directly at run start, scoped to the repo. This also bypasses
org SAML enforcement that blocks user OAuth tokens. Drop the now-dead
cross-process cache writes in the webhook reviewer-dispatch handlers, and stop
leave_failure_comment raising on the github_push source.

fix: reviewer publishes against stale head_sha on mid-run re-review (#1393)
* fix: resolve reviewer head_sha from thread metadata, not frozen run config

A push that lands while a reviewer run is in flight is delivered as a
queued message into that run. The run's configurable is frozen at
creation, so its head_sha still names the commit the run was created for
— not the commit just pushed. publish_review then anchored the GitHub
review to the stale commit and regressed last_reviewed_sha to it, and
add_finding/update_finding stamped findings with the stale SHA.

Persist the current head in thread metadata at every reviewer dispatch
(both the ready-for-review and push paths, before they branch to create
a run or queue a message), and add resolve_review_head_sha() which
prefers the metadata head over the run config. Wire it into
publish_review (review commit_id + last_reviewed_sha), add_finding
(first_seen_sha) and update_finding (last_confirmed_sha). Falls back to
the run config when metadata carries no head (first review, eval, tests).

* fix: persist head_sha in manual review dispatch (trigger_pr_review_from_ref)

resolve_review_head_sha prefers metadata[head_sha] over the run config,
and the push/ready dispatchers write it — but trigger_pr_review_from_ref
(Slack/GitHub @open-swe review, request_pr_review tool) created a run
with a freshly-fetched config head while leaving metadata's head stale
from a prior dispatch. A manual re-review at a newer commit would then
resolve to the old head and publish/advance findings against it.

Persist head_sha in that dispatch's metadata write too, so every
run-creating reviewer dispatch keeps metadata in sync with the head its
run targets. Caught by the Open SWE reviewer on this PR.

fix: scope public reviewer tokens (#1389)
* fix: scope public reviewer tokens

Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com>

* refactor: simplify reviewer token wiring; fix push re-scope + red test

- Remove the redundant _check_or_recreate_sandbox_for_proxy /
  _refresh_github_proxy_or_recreate_for_proxy wrappers and call the
  underlying functions directly (they already default the token to None).
- process_github_push_event: re-scope the GitHub App token when the push
  payload lacked repo privacy/id but PR metadata reveals a public repo, so
  reviewer.py never proxies a full-installation token for a public PR.
- Clarify the two-token sequence in trigger_pr_review_from_ref.
- Fix pre-existing failing test test_proxy_refresh_failure_recreates_sandbox
  and add coverage for _reviewer_token_for_repo + push-event scoping.

feat: TTL and revocation handling for cached GitHub OAuth tokens [closes AB-2322] (#1280)
* feat: TTL and revocation handling for cached GitHub OAuth tokens [closes AB-2322]

Persist github_token_expires_at alongside github_token_encrypted, treat
expired cache entries as missing so we re-resolve before kicking off
runs, and invalidate the cached ciphertext on a downstream 401 so the
next invocation gets a fresh token instead of replaying a revoked one.

* webapp: forward installation-token expiry to reviewer cache writes

The three reviewer-thread persist sites in webapp.py were calling
get_github_app_installation_token() (no expiry) and persist_encrypted_github_token
without expires_at, so cached App tokens were treated as never-expiring even
though they actually expire in ~1 hour.

feat: implement reviewer findings, publish_review, and watch mode (#1253)
* feat: implement reviewer findings, publish_review, and watch mode

Build out the reviewer agent end-to-end against the design in
REVIEWER_DESIGN.md:

- Findings as first-class state on the reviewer thread metadata
  (`agent/reviewer_findings.py`): Finding TypedDict with start_line/end_line
  ranges, suggestion text for ```suggestion blocks, github_review_comment_id
  for cross-run reconciliation, diff_hunk for UI rendering. Thread-level
  metadata gets `kind=reviewer`, `pr`, `last_reviewed_sha`, `watch` so a
  future frontend can list reviewer threads via the langgraph SDK.
- Diff utilities (`agent/reviewer_diff.py`): parse_unified_diff,
  compute_diff_line_set for in-diff validation, extract_diff_hunk for
  caching the hunk on a Finding, compute_diff_in_sandbox for SHA-to-SHA
  diffs against the prepped repo.
- Tools: `add_finding` (validates against the diff line set so out-of-diff
  ranges fail at creation, not at GitHub-publish), `update_finding`,
  `list_findings`, `publish_review`. The reviewer agent's tool list is
  swapped from `[]` (direct shell `gh api` calls) to these four.
- Publish path (`agent/reviewer_publish.py` + `agent/tools/publish_review.py`):
  one POST /reviews call with body + inline comments + ```suggestion blocks,
  per-comment IDs stored back on findings, GraphQL `resolveReviewThread`
  fired for findings transitioning open->resolved on a re-review.
- Reviewer graph: deterministic clone-or-fetch + checkout in the factory
  before the agent's first model call (warm- and cold-path symmetric);
  computed diff and in-diff line set passed via runnable config; system
  prompt rewritten for the single-evolving-findings model, severity ladder,
  in-diff-only discipline, and watch-mode reconciliation flow.
- Watch mode in webapp.py: `push` event + `pull_request` closed/reopened
  added to supported events. New `process_github_push_event` resolves the
  open PR for the pushed branch, gates on the reviewer thread's `watch`
  flag, builds a re-review configurable, and triggers a run on the same
  canonical thread. `process_github_pr_close` toggles watch on
  closed/reopened. `set_reviewer_thread_metadata` is called on first
  review to install `kind=reviewer` + PR identity + watch=True.
- Eval harness: target.py now extracts `add_finding` calls (mapped to the
  legacy {file, line, body, severity} shape the judge expects) and passes
  the right configurable so the prep step has base/head SHAs.
- Tests: new unit suites for findings helpers, diff parsing, finding tools,
  publish rendering + GraphQL resolve, and watch-mode webhook handlers
  (push triggers re-review only when watching, idempotent on unchanged
  head SHA, PR close disables watch). Updated existing reviewer-webhook
  tests to mock `set_reviewer_thread_metadata`.
- REVIEWER_EVAL_PLAN.md removed per user request; folded relevant context
  into REVIEWER_DESIGN.md.

* fix(reviewer): correct git diff flags, scope, dedup, and review-comments URL

Address PR #1253 review findings:

- compute_diff_in_sandbox dropped the invalid `--no-prefix=false` flag
  (`option no-prefix takes no value` — every prep run was failing
  silently and the agent saw an empty diff).
- compute_diff_in_sandbox grew a `merge_base` flag. First-review path
  now uses three-dot `base...head` (the merge-base diff GitHub renders
  on Files-changed) so we don't pick up changes that landed on the base
  branch after the PR diverged. Re-review delta keeps two-dot
  `last_reviewed_sha..head` since that's exactly the new commits.
- publish_review skips findings that already carry
  `github_review_comment_id`. Without this, watched re-reviews
  re-posted every previously surfaced finding, and only the most-recent
  duplicate's id would later resolve when the issue got addressed.
- fetch_review_comments URL now includes `{pull_number}` —
  `/repos/{owner}/{repo}/pulls/{pr_number}/reviews/{review_id}/comments`
  is the canonical endpoint; the old form 404s, so comment ids were
  never stored and watch-mode resolution couldn't run.

Three new tests cover: three-dot vs two-dot wiring, no `--no-prefix`
flag in the executed command, and that publish_review does not re-post
findings whose `github_review_comment_id` is set.

* fix(reviewer): default publish cap from 15 to 4

A clean PR with one critical issue padded out by three lower-severity
findings is fine; fifteen is review spam. The agent can override per
call when a PR genuinely warrants more.
