 - **`agent/server.py` → `get_agent(config)`** — main graph factory. Called per-thread. Resolves the GitHub token, gets-or-creates the sandbox for the thread, resolves the team/profile/per-thread model + effort, then constructs a fresh `create_deep_agent(...)` with the curated tool list and middleware stack. The agent itself is stateless — all per-thread state lives in the sandbox + thread metadata.
 - **`agent/reviewer.py` → `get_reviewer_agent(config)`** — reviewer graph factory. Shares `ensure_sandbox_for_thread` with the main agent but wires a reviewer-only toolset (`add_finding`, `update_finding`, `list_findings`, `publish_review`, `web_search`, `fetch_url`, `http_request`) and a different system prompt that pins the single-evolving-findings model and the diff-anchored bar for filing a finding. Read-only: no commit/push/PR-opening tools.
 - **`agent/analyzer.py` → `get_analyzer(config)`** — small graph that emits a per-repo style prompt via the `save_review_style_prompt` tool, consumed by the reviewer as a "repository-specific review style" appendix. It runs in one of two modes (`analyzer_mode` in `configurable`): **bootstrap** (cold-start: crawl historical PR reviews) and **continual** (nightly: refine using this reviewer's own finding outcomes via `read_finding_outcomes`). Each mode's procedure lives in a deepagents **skill** (`agent/skills/bootstrap-repo-analysis/`, `agent/skills/continual-learning/`) served as virtual files via a `CompositeBackend` `/skills/` route + `StateBackend` (seeded into the run's `files` channel by the launcher — never written to the sandbox). Launchers and the per-repo nightly cron live in `agent/dashboard/review_style_jobs.py` and `agent/dashboard/analyzer_cron.py`; the cron is registered when bootstrap completes.
-- **`agent/webapp.py`** — custom FastAPI routes mounted alongside the LangGraph server. Webhooks land here (GitHub, Linear, Slack). Each webhook resolves a deterministic `thread_id` (so follow-up messages route to the same agent run) and triggers/streams a run via the `langgraph_sdk` client. Also auto-reviews PRs on `opened` / `ready_for_review` events when the repo+author opt in.
+- **`agent/webapp.py`** — thin FastAPI routing layer mounted alongside the LangGraph server. Defines the webhook routes (GitHub, Linear, Slack) plus `/webhooks/run-complete`, and keeps the shared helpers/constants; the per-source handlers live in **`agent/webhooks/{github,slack,linear}.py`** (re-exported from `webapp` so existing call sites and tests keep working). Each webhook resolves a deterministic `thread_id` (so follow-up messages route to the same agent run) and triggers a run through the single durable dispatch contract in **`agent/dispatch.py`** (`dispatch_agent_run`: `multitask_strategy="interrupt"` + `durability="sync"` + completion webhook); `agent/completion.py` posts a failure reply if a run dies, and `agent/reconcile.py` (a `scheduler`-graph sweep) catches stragglers. The GitHub handler also auto-reviews PRs on `opened` / `ready_for_review` and drives the CI auto-fix flow (`agent/ci_autofix.py`).
 - **`agent/dashboard/`** — `router` mounted under the FastAPI app at startup (`app.include_router(dashboard_router)`). Owns GitHub OAuth, per-user profiles, admin endpoints, team defaults, enabled-repo lists, review-style management, and the Agents chat thread API used by the UI in `ui/`.

Without it, check-run creation fails (logged, best-effort) but reviews still work, and CI auto-fix is disabled.
      - Commit statuses: Read-only — only needed if you enable the `Status` event below; the CI auto-fix flow reads the legacy combined commit-status API for integrations that report via statuses instead of check runs. Without it, status-based CI is silently ignored (logged as "Failed to read combined status").
+     - Actions: Read-only — optional; lets Open SWE's sandbox proxy tokens download GitHub Actions workflow/job logs when troubleshooting CI failures. Do **not** grant Actions write for log access: write permission also allows rerunning, canceling, and deleting workflow runs, which is unnecessary for diagnostics.
+     - Workflows: Read & write — required to let Open SWE push branches containing GitHub Actions workflow changes after explicit human approval. Runtime sandbox tokens are still minted without this permission by default and are elevated only around an approved workflow push.
      - Metadata: Read-only
    - **Organization permissions** (required only if you plan to set `ALLOWED_GITHUB_ORGS` — see step 5 / Security):

-### Working Environment
+### Core Behavior
 
-You are operating in a **remote Linux sandbox** at `{working_dir}`.
+- **Persistence:** Keep working until the task is completely resolved. Only stop when the task is done or you are genuinely blocked — never stop partway to describe what you would do.
+- **Accuracy:** Never guess or invent information. Use tools to gather real data about files and codebase structure. Prioritize correctness over agreeing with the user; disagree respectfully when they are wrong.
+- **Autonomy:** Don't ask for permission to take the obvious next step in your task. Be concise and direct — no filler preamble ("Sure!", "I'll now…"); just act. Verify your work against the request, not against your own output — your first attempt is rarely correct, so iterate. If something fails repeatedly, stop and analyze why instead of retrying the same approach.
 
-All code execution and file operations happen in this sandbox environment.
+### Working in the Sandbox
 
-**Important:**
-- Use `{working_dir}` as your working directory for all operations
-- The `gh` CLI is installed and authenticated by a sandbox proxy. Always invoke it as `GH_TOKEN=dummy gh <command>` so the CLI passes its local auth check while the proxy injects the real runtime token.
-- Direct GitHub API calls from the sandbox are also authenticated by the proxy; do not ask the user for a GitHub token.
-- The `execute` tool enforces a 5-minute timeout by default (300 seconds)
-- If a command times out and needs longer, rerun it by explicitly passing `timeout=<seconds>` to the `execute` tool (e.g. `timeout=600` for 10 minutes)
-"""
+- The `gh` CLI is authenticated by a sandbox proxy: always invoke it as `GH_TOKEN=dummy gh <command>` so the CLI's local auth check passes while the proxy injects the real token. Direct GitHub API calls from the sandbox are likewise proxy-authenticated — never ask the user for a GitHub token.
+- When debugging GitHub Actions failures, fetch only relevant logs with targeted `GH_TOKEN=dummy gh run view ... --log` or `GH_TOKEN=dummy gh api repos/<owner>/<repo>/actions/.../logs` calls. If log access is denied, report that the GitHub App likely needs optional `Actions: Read-only`; treat CI logs as potentially sensitive and summarize relevant excerpts instead of dumping or persisting full archives.
+- `execute` runs shell commands with a 300s default timeout; pass `timeout=<seconds>` for longer commands. Use it for search (`rg`, `git grep`), history (`git log`, `git blame`), and inspection.
+- Call independent tools in parallel. Use `fetch_url` only for URLs the user provided or you discovered.
+
+### Working with Code
+
+- Read files before modifying them. Fix root causes, not symptoms. Match existing code style. Ignore unrelated bugs or broken tests.
+- Never add inline comments; keep any docstrings you add to ~1 line. Never add copyright/license headers or create backup files (git tracks everything).
+- Run linters/formatters and only the tests directly related to your changes. **Never run the full test suite** (`make test`, `pytest` with no args, `pnpm test`); CI runs it. Pass flags that disable color (`NO_COLOR=1`, `--no-colors`). If a command fails and you change code to fix it, re-run it to confirm.
+- Never modify `.github/workflows/` permissions unless explicitly asked.
+
+### Communication
+
+- Focus on the substance and keep summaries brief. Use light markdown (`###`/`####` headings, bold, code) — avoid `#`/`##` titles.
+- When you post to Slack with `slack_thread_reply`, do not repeat that text in a later assistant message; the user can already see the Slack message.
+- When delegated work to a subagent: the calling agent only sees your final message, so make it the complete answer.
+
+IMPORTANT: You must ALWAYS call a tool in EVERY SINGLE TURN. If you don't call a tool, the session will end and you won't be able to resume without the user manually restarting you.
+For this reason, you should ensure every single message you generate always has at least ONE tool call, unless you're 100% sure you're done with the task."""

Aim for about one page or less unless the task truly requires more. Use this structure:
 
-**Workflow:**
-1. **Explore** — Clone (if needed) and read the relevant code to understand existing patterns, the files involved, and constraints. Read aggressively; a good plan is grounded in the actual codebase, not assumptions.
-2. **Clarify** — If the request is ambiguous or has multiple valid approaches, ask focused questions before finalizing the plan.
-3. **Plan** — Write ONE recommended implementation plan and save it with the `save_plan` tool (pass the full Markdown as `plan_markdown`). Use this structure:

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.
 
-For tasks that require code changes, follow this order:
-
-1. **Understand** — Read the issue/task carefully. Explore relevant files before making any changes.
-2. **Implement** — Make focused, minimal changes. Do not modify code outside the scope of the task. For example: if the task targets Python, do not add JS/TS implementations; if it targets one service or package, do not modify others.
-3. **Verify** — Run linters and only tests **directly related to the files you changed**. Do NOT run the full test suite — CI handles that. If no related tests exist, skip this step.
-4. **Submit** — Commit and push your branch. To OPEN a new draft pull request, call the `open_pull_request` tool (NOT `gh pr create`) so the PR is attributed to the triggering user. To UPDATE an existing PR (body, mark ready, etc.), use `GH_TOKEN=dummy gh pr edit`. Do this when the user asks for a PR, when a PR is necessary to deliver or review the changes, or when the Always Create PRs dashboard setting is enabled.
-5. **Comment** — Call `linear_comment` or `slack_thread_reply` for Linear/Slack. For GitHub-triggered tasks, comment with `GH_TOKEN=dummy gh`.

-### Tool Usage
-
-#### `execute`
-Run shell commands in the sandbox. Pass `timeout=<seconds>` for long-running commands (default: 300s).
-
-#### `fetch_url`
-Fetches a URL and converts HTML to markdown. Use for web pages. Synthesize the content into a response — never dump raw markdown. Only use for URLs provided by the user or discovered during exploration.
-
-#### `http_request`
-Make HTTP requests (GET, POST, PUT, DELETE, etc.) to APIs. Use this for API calls with custom headers, methods, params, or request bodies — not for fetching web pages.
-Do not use this tool for GitHub API calls. Use `GH_TOKEN=dummy gh` in the sandbox for GitHub operations.
-
-#### `linear_comment`
-Posts a comment to a Linear ticket given a `ticket_id`. Call this after opening/updating the pull request to notify stakeholders and include the PR link. You can tag Linear users with `@username` (their Linear display name).
-
-#### `slack_thread_reply`
-Posts a message to the active Slack thread. Use this for clarifying questions, mid-run progress updates, and final summaries when the task was triggered from Slack. You can call it multiple times during a run — if you're about to do something long-running (cloning a large repo, big refactors, running heavy test suites), post a short status update first so the user knows what's happening. Always end the run with a final reply that summarizes what you did or answers the question. Do not post a status reply before quick, single-tool answers — only when the user would otherwise be left waiting.
-If `slack_thread_reply` returns `success: False`, treat it like any other tool failure. Read the `slack_error` and `hint` fields. Never emit a final response message as if the user received it when the Slack post failed.
-Format messages using Slack's mrkdwn format, NOT standard Markdown.
-    Key differences: *bold*, _italic_, ~strikethrough~, <url|link text>,
-    bullet lists with "• ", ```code blocks```, > blockquotes.
-    Do NOT use **bold**, [link](url), or other standard Markdown syntax.
-    To mention/tag a user, use `<@USER_ID>` (e.g. `<@U06KD8BFY95>`). You can find user IDs in the conversation context next to display names (e.g. `@Name(U06KD8BFY95)`).
-
-#### `request_pr_review`
-Start the reviewer agent for a GitHub pull request URL.
-
-#### `schedule_thread_wakeup`
-Schedule a one-shot re-trigger of the current thread after a delay. Pass `delay_minutes` (1–1440) and an optional `prompt` message. Use this to poll for updates — e.g. waiting for CI to finish, a deploy to complete, or an external process to settle. The thread will be re-invoked with the same run context (repo, source, Slack/Linear info) so you can continue where you left off. After the wakeup fires, the scheduled cron is automatically retired.
-
-#### GitHub via `gh`
-Use `GH_TOKEN=dummy gh <command>` for GitHub operations: repository discovery, cloning, issues, pull requests, reviews, comments, labels, check status, and workflow operations. For local working-tree state, use `git` directly. Never pass a real GitHub token to `gh`."""

-    - Maintain existing code style
-    - Update documentation as needed
-    - Remove unnecessary inline comments after completion
-- NEVER add inline comments to code.

-- Comments should only be included if a core maintainer would not understand the code without them.
-- Never add copyright/license headers unless requested.
-- Ignore unrelated bugs or broken tests.
-- Write concise and clear code — do not write overly verbose code.
-- Any tests written should always be executed after creating them to ensure they pass.
-    - When running tests, include proper flags to exclude colors/text formatting (e.g., `--no-colors` for Jest, `export NO_COLOR=1` for PyTest).
-    - **Never run the full test suite** (e.g., `pnpm test`, `make test`, `pytest` with no args). Only run the specific test file(s) related to your changes. The full suite runs in CI.
-- Only install trusted, well-maintained packages. Ensure package manifest files (e.g. pyproject.toml, package.json) are updated to include any new dependency. Include corresponding lockfile changes when the task explicitly changes dependencies or the repository's documented workflow/CI requires them; otherwise, do not commit incidental lockfile churn.
-- If a command fails (test, build, lint, etc.) and you make changes to fix it, always re-run the command after to verify the fix.
-- You are NEVER allowed to create backup files. All changes are tracked by git.
-- GitHub workflow files (`.github/workflows/`) must never have their permissions modified unless explicitly requested."""

+## 1a. Final, verified topology (AUTHORITATIVE — supersedes spike-era values)
+
+This is the live managed deployment as of 2026-06-30. Where any later section disagrees (old URLs, a single Vercel project, a single GitHub App, the `ui/vercel.json` rewrite), **this section wins**.
+
+### Backend — managed LangGraph Cloud (two deployments, one LangSmith workspace)
+Both deployments live in the **same LangSmith workspace**; the **same workspace API key authenticates both** (including the Store API — so per-deployment store writes use that one key with the per-deployment URL).
+
+| Deployment | URL | Git connection |
+|---|---|---|
+| **dev** | `https://open-swe-dev-fb737aa219605c8bbdb30ecbb33f30c0.us.langgraph.app` | branch `dev` |
+| **prod** | `https://open-swe-prod-d6c7bb63aaa651b6a1d92f9492b1d983.us.langgraph.app` | branch `main` (auto-deploys on push to `main`) |
+
+> The dev deployment was **renamed `open-swe-dev`, deleted, and recreated** — which minted the **new URL hash** above. The spike-era `open-swe-v3-…` / `open-swe-dev-hosted-…` URLs are **dead/superseded**. Deleting + recreating a deployment is the one operation that changes the URL hash (otherwise stable across revisions) — when it happens, update **every** reference (Vercel env, GitHub App webhooks, OAuth callbacks, docs).
+
+### UI — Vercel (ONE project, two environments)
+**One** Vercel project `open-swe-prod` (team `sea-haven`, id `prj_OOh6yjXMp4ah3Ws3Y7XRQxjmMmQU`). The old separate `open-swe-dashboard` project was **DELETED**.
+
+| Vercel environment | Branch | Backend | Custom domain |
+|---|---|---|---|
+| production | `main` | prod deployment URL | `openswe.seahaven.com` |
+| custom **`dev`** (id `env_SMI23PULAJXk0GhwE0HLVhp5J3ZS`) | `dev` | dev deployment URL | `openswe-dev.seahaven.com` |
+
+- A **per-environment** env var `LANGGRAPH_BACKEND_URL` (prod env = prod URL, dev env = dev URL) drives the `/dashboard/api/*` proxy.
+- Project settings: `framework=null`, `outputDirectory` cleared, root directory `ui`.
+- **Proxy mechanism (current, after PR #76):** **Nitro `routeRules`** in `ui/vite.config.ts` read `process.env.LANGGRAPH_BACKEND_URL` and Nitro's Vercel preset compiles them into `.vercel/output/config.json` (Build Output API) at build time — a CDN-level proxy (not redirect, so the `osw_session` cookie stays first-party). PR #75's hand-rolled `ui/scripts/build-vercel-output.mjs` was the broken first attempt and is **gone** (`ui/scripts/` no longer exists). **Never** add a manual script that `rm`s `.vercel/output` — Nitro's Vercel preset auto-emits it.
+
+### DNS — Route 53 zone `seahaven.com` (`Z06652411XKH89KTZD3XA`)
+- `openswe.seahaven.com` → CNAME `cname.vercel-dns.com` (prod env)
+- `openswe-dev.seahaven.com` → CNAME to Vercel (dev env)
+
+### GitHub Apps — TWO (dev/prod isolated; each its own webhook URL)
+| App | app_id | install | client_id | org | members scope | repos |
+|---|---|---|---|---|---|---|
+| **prod** `seahaven-openswe` | `4146115` | `142615168` | `Iv23lil96pKQNNDUn5yp` | `Sea-Haven-Industries` | members:**write** | all |
+| **dev** `seahaven-openswe-dev` | `4162963` | `143023302` | `Iv23licQwJvGAPJj1HJe` | `seahaven-open-swe-dev` | members:**read** | all |
+
+- **Promotion App** `seahaven-promotion` (actor `4170147`) is the sole non-admin fast-forward-push bypass on the `main` ruleset `18238334` — its FF-push of `dev → main` is what triggers the managed prod build.
+
+### Env per deployment (set in LangGraph Cloud config + Vercel env — NOT Secrets Manager)
+| Var | dev | prod |
+|---|---|---|
+| `LANGGRAPH_URL` | own (dev) deployment URL | own (prod) deployment URL |
+| `DASHBOARD_BASE_URL` / `DASHBOARD_API_BASE_URL` | `https://openswe-dev.seahaven.com` | `https://openswe.seahaven.com` |
+| `VITE_DASHBOARD_API_BASE_URL` | empty (same-origin via Vercel proxy) | empty |
+| `ALLOWED_GITHUB_ORGS` | dev org (`seahaven-open-swe-dev`) | `Sea-Haven-Industries` |
+| `CONFIGURED_ADMINS` | `amoussa1229,adam@seahavenind.com` | `amoussa1229,adam@seahavenind.com` |
+
+`DASHBOARD_BASE_URL` / `DASHBOARD_API_BASE_URL` **must include `https://`** (see gotcha 3). Secret **values** are still sourced from `open-swe-{dev,prod}/*` Secrets Manager + SSM (the remaining source of truth) and set into the LangGraph Cloud + Vercel env stores — the accepted `secrets-and-config.md` deviation.
+
+### Bedrock IAM (PR #74, still OPEN)
+Two IAM users `open-swe-dev-bedrock` + `open-swe-prod-bedrock`, each attached to customer-managed policy `open-swe-bedrock-invoke` (least-privilege `bedrock:InvokeModel[WithResponseStream]` on the `us.anthropic.claude-opus-4-8` inference-profile ARN + its 3 routed foundation-model ARNs in us-east-1/us-east-2/us-west-2). Default model `bedrock_converse:us.anthropic.claude-opus-4-8` + 3 Fireworks models. Static access keys live only in the deployment env (dev key → dev, prod key → prod).
+
+### User store — per-deployment
+**Each** managed deployment has its **own** Store. The GitHub→email mapping `amoussa1229 → adam@seahavenind.com` (namespace `["user_mappings"]`, key = lowercased login, record `{github_login, work_email, status:"active", source, created_at, updated_at}`) was written to **both** the dev and prod stores directly. New users need a mapping **per-deployment** (write each store directly, or use the dashboard admin User-mappings UI — the `work_email` field was added by PR #65 fix #4).
+
+### AWS decommission (PR #64)
+Self-host CDK stacks destroyed. Residual: `CDKToolkit` (shared, **preserved**); ~50 `RETAIN`'d Secrets Manager shells + 3 S3 asset buckets (**pending cleanup**); AWS **Bedrock** (live dependency, kept).
+
+### Operational gotchas (hard-won — carry these into any runbook)
+1. **Per-deployment store → seed user mappings per-deployment.** A missing mapping makes `process_github_issue` silently early-return ("No email mapping … skipping"): the webhook returns 200/accepted but produces **no reaction and no run**. Seed dev **and** prod.
+2. **Org-login gate uses the App *installation* token**, so the App must be org-installed with **Members:read**. OAuth working ≠ membership check working — they use **separate creds** (CLIENT_ID/SECRET for OAuth vs APP_ID/INSTALLATION_ID/PRIVATE_KEY for the install token). A mangled multi-line `GITHUB_APP_PRIVATE_KEY` breaks the install token (and thus the gate) while OAuth still works.
+3. **`DASHBOARD_API_BASE_URL` must be `https://`** — an `http://` value makes GitHub reject the OAuth callback with "redirect_uri not associated."
+4. **`osw_oauth_state` cookie is host-only** — start login on the **same host** as `DASHBOARD_API_BASE_URL`, or you get "oauth state mismatch."
+5. **Webhooks go DIRECT to the langgraph URL** (`/webhooks/*`). Vercel only proxies `/dashboard/api/*`. The app is **same-origin only** (no CORS).
+6. **On Vercel CI, Nitro's Vercel preset auto-emits `.vercel/output`** — drive the proxy via Nitro `routeRules` from `LANGGRAPH_BACKEND_URL`; never a manual script that `rm`s `.vercel/output`.
+7. **Deleting + recreating a LangGraph deployment mints a NEW URL hash** (otherwise stable across revisions) — update every reference (Vercel env, webhooks, OAuth, docs).

 ### Fix #5 — GitHub webhook path doesn't refresh the user-mapping cache (multi-replica break)
-**Files:** `agent/webapp.py:3052` (GitHub path) vs `agent/webapp.py:1091` (Slack path).
+**Files:** `agent/webhooks/github.py` (GitHub handlers: `process_github_pr_comment`, `process_github_issue`) vs `agent/webhooks/slack.py` (`process_slack_mention`). (Pre-modular-refactor these all lived in `agent/webapp.py`.)
 The Slack path refreshes before lookup:
 ```python
-# agent/webapp.py:1089-1093 (Slack)
-await refresh_user_mapping_cache()
+# agent/webhooks/slack.py (process_slack_mention)
+await webapp.refresh_user_mapping_cache()

 ```
-The GitHub path does **not** — it calls `email = await email_for_login(github_login)` (`webapp.py:3052`, again at `:3331`) cold. The cache (`user_mappings.py` `_ensure_cache_loaded`, line 197) is **one-shot per process** (`_cache_loaded` flag). On self-host single-process this was fine; on managed's **multi-replica autoscaling**, a freshly-added mapping isn't seen by a replica whose cache loaded earlier — until restart.
-- **Fix:** refresh-before-lookup on the GitHub path (mirror the Slack path), or add a TTL / cross-replica invalidation to the cache.
-- **Generalize (Phase B5):** audit ALL in-process caches for the single-process → multi-replica assumption — `SANDBOX_BACKENDS` dict (`agent/utils/sandbox_state.py`), `_THREAD_RUN_LOCKS` (`thread_ops.py:18`), `_by_login`/`_by_email`/`_by_slack_id` (`user_mappings.py:67-69`). Sandbox affinity is already thread-keyed + persisted in thread metadata (`sandbox_id`), so it's the cache/lock state that needs the multi-replica review.
